-Subject: [PATCH] Refuse dbus message paths longer than BUS_PATH_SIZE_MAX
- limit.
-
-Even though the dbus specification does not enforce any length limit on the
-path of a dbus message, having to analyze too long strings in PID1 may be
-time-consuming and it may have security impacts.
-
-In any case, the limit is set so high that real-life applications should not
-have a problem with it.
-
-(cherry picked from commit 61397a60d98e368a5720b37e83f3169e3eb511c4)

++ * enum net_device_flags - &struct net_device flags
++ *
++ * These are the &struct net_device flags, they can be set by drivers, the
++ * kernel and some can be triggered by userspace. Userspace can query and
++ * set these flags using userspace utilities but there is also a sysfs
++ * entry available for all dev flags which can be queried and set. These flags
++ * are shared for all types of net_devices. The sysfs entries are available
++ * via /sys/class/net/<dev>/flags. Flags which can be toggled through sysfs
++ * are annotated below, note that only a few flags can be toggled and some
++ * other flags are always preserved from the original net_device flags
++ * even if you try to set them via sysfs. Flags which are always preserved
++ * are kept under the flag grouping @IFF_VOLATILE. Flags which are volatile
++ * are annotated below as such.
++ *
++ * You should have a pretty good reason to be extending these flags.
++ *
++ * @IFF_UP: interface is up. Can be toggled through sysfs.
++ * @IFF_BROADCAST: broadcast address valid. Volatile.
++ * @IFF_DEBUG: turn on debugging. Can be toggled through sysfs.
++ * @IFF_LOOPBACK: is a loopback net. Volatile.
++ * @IFF_POINTOPOINT: interface is has p-p link. Volatile.
++ * @IFF_NOTRAILERS: avoid use of trailers. Can be toggled through sysfs.
++ * Volatile.
++ * @IFF_RUNNING: interface RFC2863 OPER_UP. Volatile.
++ * @IFF_NOARP: no ARP protocol. Can be toggled through sysfs. Volatile.
++ * @IFF_PROMISC: receive all packets. Can be toggled through sysfs.
++ * @IFF_ALLMULTI: receive all multicast packets. Can be toggled through
++ * sysfs.
++ * @IFF_MASTER: master of a load balancer. Volatile.
++ * @IFF_SLAVE: slave of a load balancer. Volatile.
++ * @IFF_MULTICAST: Supports multicast. Can be toggled through sysfs.
++ * @IFF_PORTSEL: can set media type. Can be toggled through sysfs.
++ * @IFF_AUTOMEDIA: auto media select active. Can be toggled through sysfs.
++ * @IFF_DYNAMIC: dialup device with changing addresses. Can be toggled
++ * through sysfs.
++ * @IFF_LOWER_UP: driver signals L1 up. Volatile.
++ * @IFF_DORMANT: driver signals dormant. Volatile.
++ * @IFF_ECHO: echo sent packets. Volatile.

++ * Compatibility interface for userspace libc header coordination:
++ *
++ * Define compatibility macros that are used to control the inclusion or
++ * exclusion of UAPI structures and definitions in coordination with another
++ * userspace C library.
++ *
++ * This header is intended to solve the problem of UAPI definitions that
++ * conflict with userspace definitions. If a UAPI header has such conflicting
++ * definitions then the solution is as follows:
++ *
++ * * Synchronize the UAPI header and the libc headers so either one can be
++ * used and such that the ABI is preserved. If this is not possible then
++ * no simple compatibility interface exists (you need to write translating
++ * wrappers and rename things) and you can't use this interface.
++ *
++ * Then follow this process:
++ *
++ * (a) Include libc-compat.h in the UAPI header.
++ * e.g. #include <linux/libc-compat.h>
++ * This include must be as early as possible.
++ *
++ * (b) In libc-compat.h add enough code to detect that the comflicting
++ * userspace libc header has been included first.
++ *
++ * (c) If the userspace libc header has been included first define a set of
++ * guard macros of the form __UAPI_DEF_FOO and set their values to 1, else
++ * set their values to 0.
++ *
++ * (d) Back in the UAPI header with the conflicting definitions, guard the
++ * definitions with:
++ * #if __UAPI_DEF_FOO
++ * ...
++ * #endif
++ *
++ * This fixes the situation where the linux headers are included *after* the
++ * libc headers. To fix the problem with the inclusion in the other order the
++ * userspace libc headers must be fixed like this:
++ *
++ * * For all definitions that conflict with kernel definitions wrap those
++ * defines in the following:
++ * #if !__UAPI_DEF_FOO
++ * ...
++ * #endif
++ *
++ * This prevents the redefinition of a construct already defined by the kernel.

++ *
++ * Documentation
++ * =============
++ *
++ * The below enums and macros are for interfacing with WireGuard, using generic
++ * netlink, with family WG_GENL_NAME and version WG_GENL_VERSION. It defines two
++ * methods: get and set. Note that while they share many common attributes,
++ * these two functions actually accept a slightly different set of inputs and
++ * outputs.
++ *
++ * WG_CMD_GET_DEVICE
++ * -----------------
++ *
++ * May only be called via NLM_F_REQUEST | NLM_F_DUMP. The command should contain
++ * one but not both of:
++ *
++ * WGDEVICE_A_IFINDEX: NLA_U32
++ * WGDEVICE_A_IFNAME: NLA_NUL_STRING, maxlen IFNAMESIZ - 1
++ *
++ * The kernel will then return several messages (NLM_F_MULTI) containing the
++ * following tree of nested items:
++ *
++ * WGDEVICE_A_IFINDEX: NLA_U32
++ * WGDEVICE_A_IFNAME: NLA_NUL_STRING, maxlen IFNAMESIZ - 1
++ * WGDEVICE_A_PRIVATE_KEY: len WG_KEY_LEN
++ * WGDEVICE_A_PUBLIC_KEY: len WG_KEY_LEN
++ * WGDEVICE_A_LISTEN_PORT: NLA_U16
++ * WGDEVICE_A_FWMARK: NLA_U32
++ * WGDEVICE_A_PEERS: NLA_NESTED
++ * 0: NLA_NESTED
++ * WGPEER_A_PUBLIC_KEY: len WG_KEY_LEN
++ * WGPEER_A_PRESHARED_KEY: len WG_KEY_LEN
++ * WGPEER_A_ENDPOINT: struct sockaddr_in or struct sockaddr_in6
++ * WGPEER_A_PERSISTENT_KEEPALIVE_INTERVAL: NLA_U16
++ * WGPEER_A_LAST_HANDSHAKE_TIME: struct __kernel_timespec
++ * WGPEER_A_RX_BYTES: NLA_U64
++ * WGPEER_A_TX_BYTES: NLA_U64
++ * WGPEER_A_ALLOWEDIPS: NLA_NESTED
++ * 0: NLA_NESTED
++ * WGALLOWEDIP_A_FAMILY: NLA_U16
++ * WGALLOWEDIP_A_IPADDR: struct in_addr or struct in6_addr
++ * WGALLOWEDIP_A_CIDR_MASK: NLA_U8
++ * 0: NLA_NESTED
++ * ...
++ * 0: NLA_NESTED
++ * ...
++ * ...
++ * WGPEER_A_PROTOCOL_VERSION: NLA_U32
++ * 0: NLA_NESTED
++ * ...
++ * ...
++ *
++ * It is possible that all of the allowed IPs of a single peer will not
++ * fit within a single netlink message. In that case, the same peer will
++ * be written in the following message, except it will only contain
++ * WGPEER_A_PUBLIC_KEY and WGPEER_A_ALLOWEDIPS. This may occur several
++ * times in a row for the same peer. It is then up to the receiver to
++ * coalesce adjacent peers. Likewise, it is possible that all peers will
++ * not fit within a single message. So, subsequent peers will be sent
++ * in following messages, except those will only contain WGDEVICE_A_IFNAME
++ * and WGDEVICE_A_PEERS. It is then up to the receiver to coalesce these
++ * messages to form the complete list of peers.
++ *
++ * Since this is an NLA_F_DUMP command, the final message will always be
++ * NLMSG_DONE, even if an error occurs. However, this NLMSG_DONE message
++ * contains an integer error code. It is either zero or a negative error
++ * code corresponding to the errno.
++ *
++ * WG_CMD_SET_DEVICE
++ * -----------------
++ *
++ * May only be called via NLM_F_REQUEST. The command should contain the
++ * following tree of nested items, containing one but not both of
++ * WGDEVICE_A_IFINDEX and WGDEVICE_A_IFNAME:
++ *
++ * WGDEVICE_A_IFINDEX: NLA_U32
++ * WGDEVICE_A_IFNAME: NLA_NUL_STRING, maxlen IFNAMESIZ - 1
++ * WGDEVICE_A_FLAGS: NLA_U32, 0 or WGDEVICE_F_REPLACE_PEERS if all current
++ * peers should be removed prior to adding the list below.
++ * WGDEVICE_A_PRIVATE_KEY: len WG_KEY_LEN, all zeros to remove
++ * WGDEVICE_A_LISTEN_PORT: NLA_U16, 0 to choose randomly
++ * WGDEVICE_A_FWMARK: NLA_U32, 0 to disable
++ * WGDEVICE_A_PEERS: NLA_NESTED
++ * 0: NLA_NESTED
++ * WGPEER_A_PUBLIC_KEY: len WG_KEY_LEN
++ * WGPEER_A_FLAGS: NLA_U32, 0 and/or WGPEER_F_REMOVE_ME if the
++ * specified peer should be removed rather than
++ * added/updated and/or WGPEER_F_REPLACE_ALLOWEDIPS
++ * if all current allowed IPs of this peer should be
++ * removed prior to adding the list below.
++ * WGPEER_A_PRESHARED_KEY: len WG_KEY_LEN, all zeros to remove
++ * WGPEER_A_ENDPOINT: struct sockaddr_in or struct sockaddr_in6
++ * WGPEER_A_PERSISTENT_KEEPALIVE_INTERVAL: NLA_U16, 0 to disable
++ * WGPEER_A_ALLOWEDIPS: NLA_NESTED
++ * 0: NLA_NESTED
++ * WGALLOWEDIP_A_FAMILY: NLA_U16
++ * WGALLOWEDIP_A_IPADDR: struct in_addr or struct in6_addr
++ * WGALLOWEDIP_A_CIDR_MASK: NLA_U8
++ * 0: NLA_NESTED
++ * ...
++ * 0: NLA_NESTED
++ * ...
++ * ...
++ * WGPEER_A_PROTOCOL_VERSION: NLA_U32, should not be set or used at
++ * all by most users of this API, as the
++ * most recent protocol will be used when
++ * this is unset. Otherwise, must be set
++ * to 1.
++ * 0: NLA_NESTED
++ * ...
++ * ...
++ *
++ * It is possible that the amount of configuration data exceeds that of
++ * the maximum message length accepted by the kernel. In that case, several
++ * messages should be sent one after another, with each successive one
++ * filling in information not contained in the prior. Note that if
++ * WGDEVICE_F_REPLACE_PEERS is specified in the first message, it probably
++ * should not be specified in fragments that come after, so that the list
++ * of peers is only cleared the first time but appened after. Likewise for
++ * peers, if WGPEER_F_REPLACE_ALLOWEDIPS is specified in the first message
++ * of a peer, it likely should not be specified in subsequent fragments.
++ *
++ * If an error occurs, NLMSG_ERROR will reply containing an errno.

+- * A traditional ioctl interface for the device mapper.
+- *
+- * Each device can have two tables associated with it, an
+- * 'active' table which is the one currently used by io passing
+- * through the device, and an 'inactive' one which is a table
+- * that is being prepared as a replacement for the 'active' one.
+- *
+- * DM_VERSION:
+- * Just get the version information for the ioctl interface.
+- *
+- * DM_REMOVE_ALL:
+- * Remove all dm devices, destroy all tables. Only really used
+- * for debug.
+- *
+- * DM_LIST_DEVICES:
+- * Get a list of all the dm device names.
+- *
+- * DM_DEV_CREATE:
+- * Create a new device, neither the 'active' or 'inactive' table
+- * slots will be filled. The device will be in suspended state
+- * after creation, however any io to the device will get errored
+- * since it will be out-of-bounds.
+- *
+- * DM_DEV_REMOVE:
+- * Remove a device, destroy any tables.
+- *
+- * DM_DEV_RENAME:
+- * Rename a device or set its uuid if none was previously supplied.
+- *
+- * DM_SUSPEND:
+- * This performs both suspend and resume, depending which flag is
+- * passed in.
+- * Suspend: This command will not return until all pending io to
+- * the device has completed. Further io will be deferred until
+- * the device is resumed.
+- * Resume: It is no longer an error to issue this command on an
+- * unsuspended device. If a table is present in the 'inactive'
+- * slot, it will be moved to the active slot, then the old table
+- * from the active slot will be _destroyed_. Finally the device
+- * is resumed.
+- *
+- * DM_DEV_STATUS:
+- * Retrieves the status for the table in the 'active' slot.
+- *
+- * DM_DEV_WAIT:
+- * Wait for a significant event to occur to the device. This
+- * could either be caused by an event triggered by one of the
+- * targets of the table in the 'active' slot, or a table change.
+- *
+- * DM_TABLE_LOAD:
+- * Load a table into the 'inactive' slot for the device. The
+- * device does _not_ need to be suspended prior to this command.
+- *
+- * DM_TABLE_CLEAR:
+- * Destroy any table in the 'inactive' slot (ie. abort).
+- *
+- * DM_TABLE_DEPS:
+- * Return a set of device dependencies for the 'active' table.
+- *
+- * DM_TABLE_STATUS:
+- * Return the targets status for the 'active' table.
+- *
+- * DM_TARGET_MSG:
+- * Pass a message string to the target at a specific offset of a device.
+- *
+- * DM_DEV_SET_GEOMETRY:
+- * Set the geometry of a device by passing in a string in this format:
+- *
+- * "cylinders heads sectors_per_track start_sector"
+- *
+- * Beware that CHS geometry is nearly obsolete and only provided
+- * for compatibility with dm devices that can be booted by a PC
+- * BIOS. See struct hd_geometry for range limits. Also note that
+- * the geometry is erased if the device size changes.

++ *
++ * int bpf_trace_printk(const char *fmt, u32 fmt_size, ...)
++ * Description
++ * This helper is a "printk()-like" facility for debugging. It
++ * prints a message defined by format *fmt* (of size *fmt_size*)
++ * to file *\/sys/kernel/debug/tracing/trace* from DebugFS, if
++ * available. It can take up to three additional **u64**
++ * arguments (as an eBPF helpers, the total number of arguments is
++ * limited to five).
++ *
++ * Each time the helper is called, it appends a line to the trace.
++ * The format of the trace is customizable, and the exact output
++ * one will get depends on the options set in
++ * *\/sys/kernel/debug/tracing/trace_options* (see also the
++ * *README* file under the same directory). However, it usually
++ * defaults to something like:
++ *
++ * ::
++ *
++ * telnet-470 [001] .N.. 419421.045894: 0x00000001: <formatted msg>
++ *
++ * In the above:
++ *
++ * * ``telnet`` is the name of the current task.
++ * * ``470`` is the PID of the current task.
++ * * ``001`` is the CPU number on which the task is
++ * running.
++ * * In ``.N..``, each character refers to a set of
++ * options (whether irqs are enabled, scheduling
++ * options, whether hard/softirqs are running, level of
++ * preempt_disabled respectively). **N** means that
++ * **TIF_NEED_RESCHED** and **PREEMPT_NEED_RESCHED**
++ * are set.
++ * * ``419421.045894`` is a timestamp.
++ * * ``0x00000001`` is a fake value used by BPF for the
++ * instruction pointer register.
++ * * ``<formatted msg>`` is the message formatted with
++ * *fmt*.
++ *
++ * The conversion specifiers supported by *fmt* are similar, but
++ * more limited than for printk(). They are **%d**, **%i**,
++ * **%u**, **%x**, **%ld**, **%li**, **%lu**, **%lx**, **%lld**,
++ * **%lli**, **%llu**, **%llx**, **%p**, **%s**. No modifier (size
++ * of field, padding with zeroes, etc.) is available, and the
++ * helper will return **-EINVAL** (but print nothing) if it
++ * encounters an unknown specifier.
++ *
++ * Also, note that **bpf_trace_printk**\ () is slow, and should
++ * only be used for debugging purposes. For this reason, a notice
++ * bloc (spanning several lines) is printed to kernel logs and
++ * states that the helper should not be used "for production use"
++ * the first time this helper is used (or more precisely, when
++ * **trace_printk**\ () buffers are allocated). For passing values
++ * to user space, perf events should be preferred.
++ * Return
++ * The number of bytes written to the buffer, or a negative error
++ * in case of failure.
++ *
++ * u32 bpf_get_prandom_u32(void)
++ * Description
++ * Get a pseudo-random number.
++ *
++ * From a security point of view, this helper uses its own
++ * pseudo-random internal state, and cannot be used to infer the
++ * seed of other random functions in the kernel. However, it is
++ * essential to note that the generator used by the helper is not
++ * cryptographically secure.
++ * Return
++ * A random 32-bit unsigned value.
++ *
++ * u32 bpf_get_smp_processor_id(void)
++ * Description
++ * Get the SMP (symmetric multiprocessing) processor id. Note that
++ * all programs run with preemption disabled, which means that the
++ * SMP processor id is stable during all the execution of the
++ * program.
++ * Return
++ * The SMP id of the processor running the program.
++ *
++ * int bpf_skb_store_bytes(struct sk_buff *skb, u32 offset, const void *from, u32 len, u64 flags)
++ * Description
++ * Store *len* bytes from address *from* into the packet
++ * associated to *skb*, at *offset*. *flags* are a combination of
++ * **BPF_F_RECOMPUTE_CSUM** (automatically recompute the
++ * checksum for the packet after storing the bytes) and
++ * **BPF_F_INVALIDATE_HASH** (set *skb*\ **->hash**, *skb*\
++ * **->swhash** and *skb*\ **->l4hash** to 0).
++ *
++ * A call to this helper is susceptible to change the underlaying
++ * packet buffer. Therefore, at load time, all checks on pointers
++ * previously done by the verifier are invalidated and must be
++ * performed again, if the helper is used in combination with
++ * direct packet access.
++ * Return
++ * 0 on success, or a negative error in case of failure.
++ *
++ * int bpf_l3_csum_replace(struct sk_buff *skb, u32 offset, u64 from, u64 to, u64 size)
++ * Description
++ * Recompute the layer 3 (e.g. IP) checksum for the packet
++ * associated to *skb*. Computation is incremental, so the helper
++ * must know the former value of the header field that was
++ * modified (*from*), the new value of this field (*to*), and the
++ * number of bytes (2 or 4) for this field, stored in *size*.
++ * Alternatively, it is possible to store the difference between
++ * the previous and the new values of the header field in *to*, by
++ * setting *from* and *size* to 0. For both methods, *offset*
++ * indicates the location of the IP checksum within the packet.
++ *
++ * This helper works in combination with **bpf_csum_diff**\ (),
++ * which does not update the checksum in-place, but offers more
++ * flexibility and can handle sizes larger than 2 or 4 for the
++ * checksum to update.
++ *
++ * A call to this helper is susceptible to change the underlaying
++ * packet buffer. Therefore, at load time, all checks on pointers
++ * previously done by the verifier are invalidated and must be
++ * performed again, if the helper is used in combination with
++ * direct packet access.
++ * Return
++ * 0 on success, or a negative error in case of failure.
++ *
++ * int bpf_l4_csum_replace(struct sk_buff *skb, u32 offset, u64 from, u64 to, u64 flags)
++ * Description
++ * Recompute the layer 4 (e.g. TCP, UDP or ICMP) checksum for the
++ * packet associated to *skb*. Computation is incremental, so the
++ * helper must know the former value of the header field that was
++ * modified (*from*), the new value of this field (*to*), and the
++ * number of bytes (2 or 4) for this field, stored on the lowest
++ * four bits of *flags*. Alternatively, it is possible to store
++ * the difference between the previous and the new values of the
++ * header field in *to*, by setting *from* and the four lowest
++ * bits of *flags* to 0. For both methods, *offset* indicates the
++ * location of the IP checksum within the packet. In addition to
++ * the size of the field, *flags* can be added (bitwise OR) actual
++ * flags. With **BPF_F_MARK_MANGLED_0**, a null checksum is left
++ * untouched (unless **BPF_F_MARK_ENFORCE** is added as well), and
++ * for updates resulting in a null checksum the value is set to
++ * **CSUM_MANGLED_0** instead. Flag **BPF_F_PSEUDO_HDR** indicates
++ * the checksum is to be computed against a pseudo-header.
++ *
++ * This helper works in combination with **bpf_csum_diff**\ (),
++ * which does not update the checksum in-place, but offers more
++ * flexibility and can handle sizes larger than 2 or 4 for the
++ * checksum to update.
++ *
++ * A call to this helper is susceptible to change the underlaying
++ * packet buffer. Therefore, at load time, all checks on pointers
++ * previously done by the verifier are invalidated and must be
++ * performed again, if the helper is used in combination with
++ * direct packet access.
++ * Return
++ * 0 on success, or a negative error in case of failure.
++ *
++ * int bpf_tail_call(void *ctx, struct bpf_map *prog_array_map, u32 index)
++ * Description
++ * This special helper is used to trigger a "tail call", or in
++ * other words, to jump into another eBPF program. The same stack
++ * frame is used (but values on stack and in registers for the
++ * caller are not accessible to the callee). This mechanism allows
++ * for program chaining, either for raising the maximum number of
++ * available eBPF instructions, or to execute given programs in
++ * conditional blocks. For security reasons, there is an upper
++ * limit to the number of successive tail calls that can be
++ * performed.
++ *
++ * Upon call of this helper, the program attempts to jump into a
++ * program referenced at index *index* in *prog_array_map*, a
++ * special map of type **BPF_MAP_TYPE_PROG_ARRAY**, and passes
++ * *ctx*, a pointer to the context.
++ *
++ * If the call succeeds, the kernel immediately runs the first
++ * instruction of the new program. This is not a function call,
++ * and it never returns to the previous program. If the call
++ * fails, then the helper has no effect, and the caller continues
++ * to run its subsequent instructions. A call can fail if the
++ * destination program for the jump does not exist (i.e. *index*
++ * is superior to the number of entries in *prog_array_map*), or
++ * if the maximum number of tail calls has been reached for this
++ * chain of programs. This limit is defined in the kernel by the
++ * macro **MAX_TAIL_CALL_CNT** (not accessible to user space),
++ * which is currently set to 32.
++ * Return
++ * 0 on success, or a negative error in case of failure.
++ *
++ * int bpf_clone_redirect(struct sk_buff *skb, u32 ifindex, u64 flags)
++ * Description
++ * Clone and redirect the packet associated to *skb* to another
++ * net device of index *ifindex*. Both ingress and egress
++ * interfaces can be used for redirection. The **BPF_F_INGRESS**
++ * value in *flags* is used to make the distinction (ingress path
++ * is selected if the flag is present, egress path otherwise).
++ * This is the only flag supported for now.
++ *
++ * In comparison with **bpf_redirect**\ () helper,
++ * **bpf_clone_redirect**\ () has the associated cost of
++ * duplicating the packet buffer, but this can be executed out of
++ * the eBPF program. Conversely, **bpf_redirect**\ () is more
++ * efficient, but it is handled through an action code where the
++ * redirection happens only after the eBPF program has returned.
++ *
++ * A call to this helper is susceptible to change the underlaying
++ * packet buffer. Therefore, at load time, all checks on pointers
++ * previously done by the verifier are invalidated and must be
++ * performed again, if the helper is used in combination with
++ * direct packet access.
++ * Return
++ * 0 on success, or a negative error in case of failure.
+ *

++ *
++ * int bpf_get_current_comm(char *buf, u32 size_of_buf)
++ * Description
++ * Copy the **comm** attribute of the current task into *buf* of
++ * *size_of_buf*. The **comm** attribute contains the name of
++ * the executable (excluding the path) for the current task. The
++ * *size_of_buf* must be strictly positive. On success, the
++ * helper makes sure that the *buf* is NUL-terminated. On failure,
++ * it is filled with zeroes.
++ * Return
++ * 0 on success, or a negative error in case of failure.
++ *
++ * u32 bpf_get_cgroup_classid(struct sk_buff *skb)
++ * Description
++ * Retrieve the classid for the current task, i.e. for the net_cls
++ * cgroup to which *skb* belongs.
++ *
++ * This helper can be used on TC egress path, but not on ingress.
++ *
++ * The net_cls cgroup provides an interface to tag network packets
++ * based on a user-provided identifier for all traffic coming from
++ * the tasks belonging to the related cgroup. See also the related
++ * kernel documentation, available from the Linux sources in file
++ * *Documentation/cgroup-v1/net_cls.txt*.
++ *
++ * The Linux kernel has two versions for cgroups: there are
++ * cgroups v1 and cgroups v2. Both are available to users, who can
++ * use a mixture of them, but note that the net_cls cgroup is for
++ * cgroup v1 only. This makes it incompatible with BPF programs
++ * run on cgroups, which is a cgroup-v2-only feature (a socket can
++ * only hold data for one version of cgroups at a time).
++ *
++ * This helper is only available is the kernel was compiled with
++ * the **CONFIG_CGROUP_NET_CLASSID** configuration option set to
++ * "**y**" or to "**m**".
++ * Return
++ * The classid, or 0 for the default unconfigured classid.
++ *
++ * int bpf_skb_vlan_push(struct sk_buff *skb, __be16 vlan_proto, u16 vlan_tci)
++ * Description
++ * Push a *vlan_tci* (VLAN tag control information) of protocol
++ * *vlan_proto* to the packet associated to *skb*, then update
++ * the checksum. Note that if *vlan_proto* is different from
++ * **ETH_P_8021Q** and **ETH_P_8021AD**, it is considered to
++ * be **ETH_P_8021Q**.
++ *
++ * A call to this helper is susceptible to change the underlaying
++ * packet buffer. Therefore, at load time, all checks on pointers
++ * previously done by the verifier are invalidated and must be
++ * performed again, if the helper is used in combination with
++ * direct packet access.
++ * Return
++ * 0 on success, or a negative error in case of failure.
++ *
++ * int bpf_skb_vlan_pop(struct sk_buff *skb)
++ * Description
++ * Pop a VLAN header from the packet associated to *skb*.
++ *
++ * A call to this helper is susceptible to change the underlaying
++ * packet buffer. Therefore, at load time, all checks on pointers
++ * previously done by the verifier are invalidated and must be
++ * performed again, if the helper is used in combination with
++ * direct packet access.
++ * Return
++ * 0 on success, or a negative error in case of failure.
++ *
++ * int bpf_skb_get_tunnel_key(struct sk_buff *skb, struct bpf_tunnel_key *key, u32 size, u64 flags)
++ * Description
++ * Get tunnel metadata. This helper takes a pointer *key* to an
++ * empty **struct bpf_tunnel_key** of **size**, that will be
++ * filled with tunnel metadata for the packet associated to *skb*.
++ * The *flags* can be set to **BPF_F_TUNINFO_IPV6**, which
++ * indicates that the tunnel is based on IPv6 protocol instead of
++ * IPv4.
++ *
++ * The **struct bpf_tunnel_key** is an object that generalizes the
++ * principal parameters used by various tunneling protocols into a
++ * single struct. This way, it can be used to easily make a
++ * decision based on the contents of the encapsulation header,
++ * "summarized" in this struct. In particular, it holds the IP
++ * address of the remote end (IPv4 or IPv6, depending on the case)
++ * in *key*\ **->remote_ipv4** or *key*\ **->remote_ipv6**. Also,
++ * this struct exposes the *key*\ **->tunnel_id**, which is
++ * generally mapped to a VNI (Virtual Network Identifier), making
++ * it programmable together with the **bpf_skb_set_tunnel_key**\
++ * () helper.
++ *
++ * Let's imagine that the following code is part of a program
++ * attached to the TC ingress interface, on one end of a GRE
++ * tunnel, and is supposed to filter out all messages coming from
++ * remote ends with IPv4 address other than 10.0.0.1:
++ *
++ * ::
++ *
++ * int ret;
++ * struct bpf_tunnel_key key = {};
++ *
++ * ret = bpf_skb_get_tunnel_key(skb, &key, sizeof(key), 0);
++ * if (ret < 0)
++ * return TC_ACT_SHOT; // drop packet
++ *
++ * if (key.remote_ipv4 != 0x0a000001)
++ * return TC_ACT_SHOT; // drop packet
++ *
++ * return TC_ACT_OK; // accept packet
++ *
++ * This interface can also be used with all encapsulation devices
++ * that can operate in "collect metadata" mode: instead of having
++ * one network device per specific configuration, the "collect
++ * metadata" mode only requires a single device where the
++ * configuration can be extracted from this helper.
++ *
++ * This can be used together with various tunnels such as VXLan,
++ * Geneve, GRE or IP in IP (IPIP).
++ * Return
++ * 0 on success, or a negative error in case of failure.
++ *
++ * int bpf_skb_set_tunnel_key(struct sk_buff *skb, struct bpf_tunnel_key *key, u32 size, u64 flags)
++ * Description
++ * Populate tunnel metadata for packet associated to *skb.* The
++ * tunnel metadata is set to the contents of *key*, of *size*. The
++ * *flags* can be set to a combination of the following values:
++ *
++ * **BPF_F_TUNINFO_IPV6**
++ * Indicate that the tunnel is based on IPv6 protocol
++ * instead of IPv4.
++ * **BPF_F_ZERO_CSUM_TX**
++ * For IPv4 packets, add a flag to tunnel metadata
++ * indicating that checksum computation should be skipped
++ * and checksum set to zeroes.
++ * **BPF_F_DONT_FRAGMENT**
++ * Add a flag to tunnel metadata indicating that the
++ * packet should not be fragmented.
++ * **BPF_F_SEQ_NUMBER**
++ * Add a flag to tunnel metadata indicating that a
++ * sequence number should be added to tunnel header before
++ * sending the packet. This flag was added for GRE
++ * encapsulation, but might be used with other protocols
++ * as well in the future.
++ *
++ * Here is a typical usage on the transmit path:
++ *
++ * ::
++ *
++ * struct bpf_tunnel_key key;
++ * populate key ...
++ * bpf_skb_set_tunnel_key(skb, &key, sizeof(key), 0);
++ * bpf_clone_redirect(skb, vxlan_dev_ifindex, 0);
++ *
++ * See also the description of the **bpf_skb_get_tunnel_key**\ ()
++ * helper for additional information.
++ * Return
++ * 0 on success, or a negative error in case of failure.
++ *
++ * u64 bpf_perf_event_read(struct bpf_map *map, u64 flags)
++ * Description
++ * Read the value of a perf event counter. This helper relies on a
++ * *map* of type **BPF_MAP_TYPE_PERF_EVENT_ARRAY**. The nature of
++ * the perf event counter is selected when *map* is updated with
++ * perf event file descriptors. The *map* is an array whose size
++ * is the number of available CPUs, and each cell contains a value
++ * relative to one CPU. The value to retrieve is indicated by
++ * *flags*, that contains the index of the CPU to look up, masked
++ * with **BPF_F_INDEX_MASK**. Alternatively, *flags* can be set to
++ * **BPF_F_CURRENT_CPU** to indicate that the value for the
++ * current CPU should be retrieved.
++ *
++ * Note that before Linux 4.13, only hardware perf event can be
++ * retrieved.
++ *
++ * Also, be aware that the newer helper
++ * **bpf_perf_event_read_value**\ () is recommended over
++ * **bpf_perf_event_read**\ () in general. The latter has some ABI
++ * quirks where error and counter value are used as a return code
++ * (which is wrong to do since ranges may overlap). This issue is
++ * fixed with **bpf_perf_event_read_value**\ (), which at the same
++ * time provides more features over the **bpf_perf_event_read**\
++ * () interface. Please refer to the description of
++ * **bpf_perf_event_read_value**\ () for details.
++ * Return
++ * The value of the perf event counter read from the map, or a
++ * negative error code in case of failure.
++ *
++ * int bpf_redirect(u32 ifindex, u64 flags)
++ * Description
++ * Redirect the packet to another net device of index *ifindex*.
++ * This helper is somewhat similar to **bpf_clone_redirect**\
++ * (), except that the packet is not cloned, which provides
++ * increased performance.
++ *
++ * Except for XDP, both ingress and egress interfaces can be used
++ * for redirection. The **BPF_F_INGRESS** value in *flags* is used
++ * to make the distinction (ingress path is selected if the flag
++ * is present, egress path otherwise). Currently, XDP only
++ * supports redirection to the egress interface, and accepts no
++ * flag at all.
++ *
++ * The same effect can be attained with the more generic
++ * **bpf_redirect_map**\ (), which requires specific maps to be
++ * used but offers better performance.
++ * Return
++ * For XDP, the helper returns **XDP_REDIRECT** on success or
++ * **XDP_ABORTED** on error. For other program types, the values
++ * are **TC_ACT_REDIRECT** on success or **TC_ACT_SHOT** on
++ * error.
++ *
++ * u32 bpf_get_route_realm(struct sk_buff *skb)
++ * Description
++ * Retrieve the realm or the route, that is to say the
++ * **tclassid** field of the destination for the *skb*. The
++ * indentifier retrieved is a user-provided tag, similar to the
++ * one used with the net_cls cgroup (see description for
++ * **bpf_get_cgroup_classid**\ () helper), but here this tag is
++ * held by a route (a destination entry), not by a task.
++ *
++ * Retrieving this identifier works with the clsact TC egress hook
++ * (see also **tc-bpf(8)**), or alternatively on conventional
++ * classful egress qdiscs, but not on TC ingress path. In case of
++ * clsact TC egress hook, this has the advantage that, internally,
++ * the destination entry has not been dropped yet in the transmit
++ * path. Therefore, the destination entry does not need to be
++ * artificially held via **netif_keep_dst**\ () for a classful
++ * qdisc until the *skb* is freed.
++ *
++ * This helper is available only if the kernel was compiled with
++ * **CONFIG_IP_ROUTE_CLASSID** configuration option.
++ * Return
++ * The realm of the route for the packet associated to *skb*, or 0
++ * if none was found.
++ *
++ * int bpf_perf_event_output(struct pt_reg *ctx, struct bpf_map *map, u64 flags, void *data, u64 size)
++ * Description
++ * Write raw *data* blob into a special BPF perf event held by
++ * *map* of type **BPF_MAP_TYPE_PERF_EVENT_ARRAY**. This perf
++ * event must have the following attributes: **PERF_SAMPLE_RAW**
++ * as **sample_type**, **PERF_TYPE_SOFTWARE** as **type**, and
++ * **PERF_COUNT_SW_BPF_OUTPUT** as **config**.
++ *
++ * The *flags* are used to indicate the index in *map* for which
++ * the value must be put, masked with **BPF_F_INDEX_MASK**.
++ * Alternatively, *flags* can be set to **BPF_F_CURRENT_CPU**
++ * to indicate that the index of the current CPU core should be
++ * used.
++ *
++ * The value to write, of *size*, is passed through eBPF stack and
++ * pointed by *data*.
++ *
++ * The context of the program *ctx* needs also be passed to the
++ * helper.
++ *
++ * On user space, a program willing to read the values needs to
++ * call **perf_event_open**\ () on the perf event (either for
++ * one or for all CPUs) and to store the file descriptor into the
++ * *map*. This must be done before the eBPF program can send data
++ * into it. An example is available in file
++ * *samples/bpf/trace_output_user.c* in the Linux kernel source
++ * tree (the eBPF program counterpart is in
++ * *samples/bpf/trace_output_kern.c*).
++ *
++ * **bpf_perf_event_output**\ () achieves better performance
++ * than **bpf_trace_printk**\ () for sharing data with user
++ * space, and is much better suitable for streaming data from eBPF
++ * programs.
++ *
++ * Note that this helper is not restricted to tracing use cases
++ * and can be used with programs attached to TC or XDP as well,
++ * where it allows for passing data to user space listeners. Data
++ * can be:
++ *
++ * * Only custom structs,
++ * * Only the packet payload, or
++ * * A combination of both.
++ * Return
++ * 0 on success, or a negative error in case of failure.
++ *
++ * int bpf_skb_load_bytes(const struct sk_buff *skb, u32 offset, void *to, u32 len)
++ * Description
++ * This helper was provided as an easy way to load data from a
++ * packet. It can be used to load *len* bytes from *offset* from
++ * the packet associated to *skb*, into the buffer pointed by
++ * *to*.
++ *
++ * Since Linux 4.7, usage of this helper has mostly been replaced
++ * by "direct packet access", enabling packet data to be
++ * manipulated with *skb*\ **->data** and *skb*\ **->data_end**
++ * pointing respectively to the first byte of packet data and to
++ * the byte after the last byte of packet data. However, it
++ * remains useful if one wishes to read large quantities of data
++ * at once from a packet into the eBPF stack.
++ * Return
++ * 0 on success, or a negative error in case of failure.
++ *
++ * int bpf_get_stackid(struct pt_reg *ctx, struct bpf_map *map, u64 flags)
++ * Description
++ * Walk a user or a kernel stack and return its id. To achieve
++ * this, the helper needs *ctx*, which is a pointer to the context
++ * on which the tracing program is executed, and a pointer to a
++ * *map* of type **BPF_MAP_TYPE_STACK_TRACE**.
++ *
++ * The last argument, *flags*, holds the number of stack frames to
++ * skip (from 0 to 255), masked with
++ * **BPF_F_SKIP_FIELD_MASK**. The next bits can be used to set
++ * a combination of the following flags:
++ *
++ * **BPF_F_USER_STACK**
++ * Collect a user space stack instead of a kernel stack.
++ * **BPF_F_FAST_STACK_CMP**
++ * Compare stacks by hash only.
++ * **BPF_F_REUSE_STACKID**
++ * If two different stacks hash into the same *stackid*,
++ * discard the old one.
++ *
++ * The stack id retrieved is a 32 bit long integer handle which
++ * can be further combined with other data (including other stack
++ * ids) and used as a key into maps. This can be useful for
++ * generating a variety of graphs (such as flame graphs or off-cpu
++ * graphs).
++ *
++ * For walking a stack, this helper is an improvement over
++ * **bpf_probe_read**\ (), which can be used with unrolled loops
++ * but is not efficient and consumes a lot of eBPF instructions.
++ * Instead, **bpf_get_stackid**\ () can collect up to
++ * **PERF_MAX_STACK_DEPTH** both kernel and user frames. Note that
++ * this limit can be controlled with the **sysctl** program, and
++ * that it should be manually increased in order to profile long
++ * user stacks (such as stacks for Java programs). To do so, use:
++ *
++ * ::
++ *
++ * # sysctl kernel.perf_event_max_stack=<new value>
++ * Return
++ * The positive or null stack id on success, or a negative error
++ * in case of failure.
++ *
++ * s64 bpf_csum_diff(__be32 *from, u32 from_size, __be32 *to, u32 to_size, __wsum seed)
++ * Description
++ * Compute a checksum difference, from the raw buffer pointed by
++ * *from*, of length *from_size* (that must be a multiple of 4),
++ * towards the raw buffer pointed by *to*, of size *to_size*
++ * (same remark). An optional *seed* can be added to the value
++ * (this can be cascaded, the seed may come from a previous call
++ * to the helper).
++ *
++ * This is flexible enough to be used in several ways:
++ *
++ * * With *from_size* == 0, *to_size* > 0 and *seed* set to
++ * checksum, it can be used when pushing new data.
++ * * With *from_size* > 0, *to_size* == 0 and *seed* set to
++ * checksum, it can be used when removing data from a packet.
++ * * With *from_size* > 0, *to_size* > 0 and *seed* set to 0, it
++ * can be used to compute a diff. Note that *from_size* and
++ * *to_size* do not need to be equal.
++ *
++ * This helper can be used in combination with
++ * **bpf_l3_csum_replace**\ () and **bpf_l4_csum_replace**\ (), to
++ * which one can feed in the difference computed with
++ * **bpf_csum_diff**\ ().
++ * Return
++ * The checksum result, or a negative error code in case of
++ * failure.
++ *
++ * int bpf_skb_get_tunnel_opt(struct sk_buff *skb, u8 *opt, u32 size)
++ * Description
++ * Retrieve tunnel options metadata for the packet associated to
++ * *skb*, and store the raw tunnel option data to the buffer *opt*
++ * of *size*.
++ *
++ * This helper can be used with encapsulation devices that can
++ * operate in "collect metadata" mode (please refer to the related
++ * note in the description of **bpf_skb_get_tunnel_key**\ () for
++ * more details). A particular example where this can be used is
++ * in combination with the Geneve encapsulation protocol, where it
++ * allows for pushing (with **bpf_skb_get_tunnel_opt**\ () helper)
++ * and retrieving arbitrary TLVs (Type-Length-Value headers) from
++ * the eBPF program. This allows for full customization of these
++ * headers.
++ * Return
++ * The size of the option data retrieved.
++ *
++ * int bpf_skb_set_tunnel_opt(struct sk_buff *skb, u8 *opt, u32 size)
++ * Description
++ * Set tunnel options metadata for the packet associated to *skb*
++ * to the option data contained in the raw buffer *opt* of *size*.
++ *
++ * See also the description of the **bpf_skb_get_tunnel_opt**\ ()
++ * helper for additional information.
++ * Return
++ * 0 on success, or a negative error in case of failure.
++ *
++ * int bpf_skb_change_proto(struct sk_buff *skb, __be16 proto, u64 flags)
++ * Description
++ * Change the protocol of the *skb* to *proto*. Currently
++ * supported are transition from IPv4 to IPv6, and from IPv6 to
++ * IPv4. The helper takes care of the groundwork for the
++ * transition, including resizing the socket buffer. The eBPF
++ * program is expected to fill the new headers, if any, via
++ * **skb_store_bytes**\ () and to recompute the checksums with
++ * **bpf_l3_csum_replace**\ () and **bpf_l4_csum_replace**\
++ * (). The main case for this helper is to perform NAT64
++ * operations out of an eBPF program.
++ *
++ * Internally, the GSO type is marked as dodgy so that headers are
++ * checked and segments are recalculated by the GSO/GRO engine.
++ * The size for GSO target is adapted as well.
++ *
++ * All values for *flags* are reserved for future usage, and must
++ * be left at zero.
++ *
++ * A call to this helper is susceptible to change the underlaying
++ * packet buffer. Therefore, at load time, all checks on pointers
++ * previously done by the verifier are invalidated and must be
++ * performed again, if the helper is used in combination with
++ * direct packet access.
++ * Return
++ * 0 on success, or a negative error in case of failure.
++ *
++ * int bpf_skb_change_type(struct sk_buff *skb, u32 type)
++ * Description
++ * Change the packet type for the packet associated to *skb*. This
++ * comes down to setting *skb*\ **->pkt_type** to *type*, except
++ * the eBPF program does not have a write access to *skb*\
++ * **->pkt_type** beside this helper. Using a helper here allows
++ * for graceful handling of errors.
++ *
++ * The major use case is to change incoming *skb*s to
++ * **PACKET_HOST** in a programmatic way instead of having to
++ * recirculate via **redirect**\ (..., **BPF_F_INGRESS**), for
++ * example.
++ *
++ * Note that *type* only allows certain values. At this time, they
++ * are:
++ *
++ * **PACKET_HOST**
++ * Packet is for us.
++ * **PACKET_BROADCAST**
++ * Send packet to all.
++ * **PACKET_MULTICAST**
++ * Send packet to group.
++ * **PACKET_OTHERHOST**
++ * Send packet to someone else.
++ * Return
++ * 0 on success, or a negative error in case of failure.
++ *
++ * int bpf_skb_under_cgroup(struct sk_buff *skb, struct bpf_map *map, u32 index)
++ * Description
++ * Check whether *skb* is a descendant of the cgroup2 held by
++ * *map* of type **BPF_MAP_TYPE_CGROUP_ARRAY**, at *index*.
++ * Return
++ * The return value depends on the result of the test, and can be:
++ *
++ * * 0, if the *skb* failed the cgroup2 descendant test.
++ * * 1, if the *skb* succeeded the cgroup2 descendant test.
++ * * A negative error code, if an error occurred.
++ *
++ * u32 bpf_get_hash_recalc(struct sk_buff *skb)
++ * Description
++ * Retrieve the hash of the packet, *skb*\ **->hash**. If it is
++ * not set, in particular if the hash was cleared due to mangling,
++ * recompute this hash. Later accesses to the hash can be done
++ * directly with *skb*\ **->hash**.
++ *
++ * Calling **bpf_set_hash_invalid**\ (), changing a packet
++ * prototype with **bpf_skb_change_proto**\ (), or calling
++ * **bpf_skb_store_bytes**\ () with the
++ * **BPF_F_INVALIDATE_HASH** are actions susceptible to clear
++ * the hash and to trigger a new computation for the next call to
++ * **bpf_get_hash_recalc**\ ().
++ * Return
++ * The 32-bit hash.
+ *
+ * u64 bpf_get_current_task(void)

+- * Return: 0 on success or negative error

+- * @delta: An positive/negative integer to be added to xdp_md.data
+- * Return: 0 on success or negative on error
++ * Return
++ * A pointer to the current task struct.
++ *
++ * int bpf_probe_write_user(void *dst, const void *src, u32 len)
++ * Description
++ * Attempt in a safe way to write *len* bytes from the buffer
++ * *src* to *dst* in memory. It only works for threads that are in
++ * user context, and *dst* must be a valid user space address.
++ *
++ * This helper should not be used to implement any kind of
++ * security mechanism because of TOC-TOU attacks, but rather to
++ * debug, divert, and manipulate execution of semi-cooperative
++ * processes.
++ *
++ * Keep in mind that this feature is meant for experiments, and it
++ * has a risk of crashing the system and running programs.
++ * Therefore, when an eBPF program using this helper is attached,
++ * a warning including PID and process name is printed to kernel
++ * logs.
++ * Return
++ * 0 on success, or a negative error in case of failure.
++ *
++ * int bpf_current_task_under_cgroup(struct bpf_map *map, u32 index)
++ * Description
++ * Check whether the probe is being run is the context of a given
++ * subset of the cgroup2 hierarchy. The cgroup2 to test is held by
++ * *map* of type **BPF_MAP_TYPE_CGROUP_ARRAY**, at *index*.
++ * Return
++ * The return value depends on the result of the test, and can be:
++ *
++ * * 0, if the *skb* task belongs to the cgroup2.
++ * * 1, if the *skb* task does not belong to the cgroup2.
++ * * A negative error code, if an error occurred.
++ *
++ * int bpf_skb_change_tail(struct sk_buff *skb, u32 len, u64 flags)
++ * Description
++ * Resize (trim or grow) the packet associated to *skb* to the
++ * new *len*. The *flags* are reserved for future usage, and must
++ * be left at zero.
++ *
++ * The basic idea is that the helper performs the needed work to
++ * change the size of the packet, then the eBPF program rewrites
++ * the rest via helpers like **bpf_skb_store_bytes**\ (),
++ * **bpf_l3_csum_replace**\ (), **bpf_l3_csum_replace**\ ()
++ * and others. This helper is a slow path utility intended for
++ * replies with control messages. And because it is targeted for
++ * slow path, the helper itself can afford to be slow: it
++ * implicitly linearizes, unclones and drops offloads from the
++ * *skb*.
++ *
++ * A call to this helper is susceptible to change the underlaying
++ * packet buffer. Therefore, at load time, all checks on pointers
++ * previously done by the verifier are invalidated and must be
++ * performed again, if the helper is used in combination with
++ * direct packet access.
++ * Return
++ * 0 on success, or a negative error in case of failure.
++ *
++ * int bpf_skb_pull_data(struct sk_buff *skb, u32 len)
++ * Description
++ * Pull in non-linear data in case the *skb* is non-linear and not
++ * all of *len* are part of the linear section. Make *len* bytes
++ * from *skb* readable and writable. If a zero value is passed for
++ * *len*, then the whole length of the *skb* is pulled.
++ *
++ * This helper is only needed for reading and writing with direct
++ * packet access.
++ *
++ * For direct packet access, testing that offsets to access
++ * are within packet boundaries (test on *skb*\ **->data_end**) is
++ * susceptible to fail if offsets are invalid, or if the requested
++ * data is in non-linear parts of the *skb*. On failure the
++ * program can just bail out, or in the case of a non-linear
++ * buffer, use a helper to make the data available. The
++ * **bpf_skb_load_bytes**\ () helper is a first solution to access
++ * the data. Another one consists in using **bpf_skb_pull_data**
++ * to pull in once the non-linear parts, then retesting and
++ * eventually access the data.
++ *
++ * At the same time, this also makes sure the *skb* is uncloned,
++ * which is a necessary condition for direct write. As this needs
++ * to be an invariant for the write part only, the verifier
++ * detects writes and adds a prologue that is calling
++ * **bpf_skb_pull_data()** to effectively unclone the *skb* from
++ * the very beginning in case it is indeed cloned.
++ *
++ * A call to this helper is susceptible to change the underlaying
++ * packet buffer. Therefore, at load time, all checks on pointers
++ * previously done by the verifier are invalidated and must be
++ * performed again, if the helper is used in combination with
++ * direct packet access.
++ * Return
++ * 0 on success, or a negative error in case of failure.
++ *
++ * s64 bpf_csum_update(struct sk_buff *skb, __wsum csum)
++ * Description
++ * Add the checksum *csum* into *skb*\ **->csum** in case the
++ * driver has supplied a checksum for the entire packet into that
++ * field. Return an error otherwise. This helper is intended to be
++ * used in combination with **bpf_csum_diff**\ (), in particular
++ * when the checksum needs to be updated after data has been
++ * written into the packet through direct packet access.
++ * Return
++ * The checksum on success, or a negative error code in case of
++ * failure.
++ *
++ * void bpf_set_hash_invalid(struct sk_buff *skb)
++ * Description
++ * Invalidate the current *skb*\ **->hash**. It can be used after
++ * mangling on headers through direct packet access, in order to
++ * indicate that the hash is outdated and to trigger a
++ * recalculation the next time the kernel tries to access this
++ * hash or when the **bpf_get_hash_recalc**\ () helper is called.
++ *
++ * int bpf_get_numa_node_id(void)
++ * Description
++ * Return the id of the current NUMA node. The primary use case
++ * for this helper is the selection of sockets for the local NUMA
++ * node, when the program is attached to sockets using the
++ * **SO_ATTACH_REUSEPORT_EBPF** option (see also **socket(7)**),
++ * but the helper is also available to other eBPF program types,
++ * similarly to **bpf_get_smp_processor_id**\ ().
++ * Return
++ * The id of current NUMA node.
++ *
++ * int bpf_skb_change_head(struct sk_buff *skb, u32 len, u64 flags)
++ * Description
++ * Grows headroom of packet associated to *skb* and adjusts the
++ * offset of the MAC header accordingly, adding *len* bytes of
++ * space. It automatically extends and reallocates memory as
++ * required.
++ *
++ * This helper can be used on a layer 3 *skb* to push a MAC header
++ * for redirection into a layer 2 device.
++ *
++ * All values for *flags* are reserved for future usage, and must
++ * be left at zero.
++ *
++ * A call to this helper is susceptible to change the underlaying
++ * packet buffer. Therefore, at load time, all checks on pointers
++ * previously done by the verifier are invalidated and must be
++ * performed again, if the helper is used in combination with
++ * direct packet access.
++ * Return
++ * 0 on success, or a negative error in case of failure.
++ *
++ * int bpf_xdp_adjust_head(struct xdp_buff *xdp_md, int delta)
++ * Description
++ * Adjust (move) *xdp_md*\ **->data** by *delta* bytes. Note that
++ * it is possible to use a negative value for *delta*. This helper
++ * can be used to prepare the packet for pushing or popping
++ * headers.
++ *
++ * A call to this helper is susceptible to change the underlaying
++ * packet buffer. Therefore, at load time, all checks on pointers
++ * previously done by the verifier are invalidated and must be
++ * performed again, if the helper is used in combination with
++ * direct packet access.
++ * Return
++ * 0 on success, or a negative error in case of failure.
+ *
+ * int bpf_probe_read_str(void *dst, int size, const void *unsafe_ptr)
+- * Copy a NUL terminated string from unsafe address. In case the string

+- * @delta: An positive/negative integer to be added to xdp_md.data_meta
+- * Return: 0 on success or negative on error

+- * read perf prog attached perf event counter and enabled/running time
+- * @ctx: pointer to ctx
+- * @buf: buf to fill

+- *
+- * int bpf_override_return(pt_regs, rc)
+- * @pt_regs: pointer to struct pt_regs
+- * @rc: the return value to set
++ * Description
++ * Copy a NUL terminated string from an unsafe address
++ * *unsafe_ptr* to *dst*. The *size* should include the
++ * terminating NUL byte. In case the string length is smaller than
++ * *size*, the target is not padded with further NUL bytes. If the
++ * string length is larger than *size*, just *size*-1 bytes are
++ * copied and the last byte is set to NUL.
++ *
++ * On success, the length of the copied string is returned. This
++ * makes this helper useful in tracing programs for reading
++ * strings, and more importantly to get its length at runtime. See
++ * the following snippet:
++ *
++ * ::
++ *
++ * SEC("kprobe/sys_open")
++ * void bpf_sys_open(struct pt_regs *ctx)
++ * {
++ * char buf[PATHLEN]; // PATHLEN is defined to 256
++ * int res = bpf_probe_read_str(buf, sizeof(buf),
++ * ctx->di);
++ *
++ * // Consume buf, for example push it to
++ * // userspace via bpf_perf_event_output(); we
++ * // can use res (the string length) as event
++ * // size, after checking its boundaries.
++ * }
++ *
++ * In comparison, using **bpf_probe_read()** helper here instead
++ * to read the string would require to estimate the length at
++ * compile time, and would often result in copying more memory
++ * than necessary.
++ *
++ * Another useful use case is when parsing individual process
++ * arguments or individual environment variables navigating
++ * *current*\ **->mm->arg_start** and *current*\
++ * **->mm->env_start**: using this helper and the return value,
++ * one can quickly iterate at the right offset of the memory area.
++ * Return
++ * On success, the strictly positive length of the string,
++ * including the trailing NUL character. On error, a negative
++ * value.
++ *
++ * u64 bpf_get_socket_cookie(struct sk_buff *skb)
++ * Description
++ * If the **struct sk_buff** pointed by *skb* has a known socket,
++ * retrieve the cookie (generated by the kernel) of this socket.
++ * If no cookie has been set yet, generate a new cookie. Once
++ * generated, the socket cookie remains stable for the life of the
++ * socket. This helper can be useful for monitoring per socket
++ * networking traffic statistics as it provides a unique socket
++ * identifier per namespace.
++ * Return
++ * A 8-byte long non-decreasing number on success, or 0 if the
++ * socket field is missing inside *skb*.
++ *
++ * u64 bpf_get_socket_cookie(struct bpf_sock_addr *ctx)
++ * Description
++ * Equivalent to bpf_get_socket_cookie() helper that accepts
++ * *skb*, but gets socket from **struct bpf_sock_addr** contex.
++ * Return
++ * A 8-byte long non-decreasing number.
++ *
++ * u64 bpf_get_socket_cookie(struct bpf_sock_ops *ctx)
++ * Description
++ * Equivalent to bpf_get_socket_cookie() helper that accepts
++ * *skb*, but gets socket from **struct bpf_sock_ops** contex.
++ * Return
++ * A 8-byte long non-decreasing number.
++ *
++ * u32 bpf_get_socket_uid(struct sk_buff *skb)
++ * Return
++ * The owner UID of the socket associated to *skb*. If the socket
++ * is **NULL**, or if it is not a full socket (i.e. if it is a
++ * time-wait or a request socket instead), **overflowuid** value
++ * is returned (note that **overflowuid** might also be the actual
++ * UID value for the socket).
++ *
++ * u32 bpf_set_hash(struct sk_buff *skb, u32 hash)
++ * Description
++ * Set the full hash for *skb* (set the field *skb*\ **->hash**)
++ * to value *hash*.
++ * Return
++ * 0
++ *
++ * int bpf_setsockopt(struct bpf_sock_ops *bpf_socket, int level, int optname, char *optval, int optlen)
++ * Description
++ * Emulate a call to **setsockopt()** on the socket associated to
++ * *bpf_socket*, which must be a full socket. The *level* at
++ * which the option resides and the name *optname* of the option
++ * must be specified, see **setsockopt(2)** for more information.
++ * The option value of length *optlen* is pointed by *optval*.
++ *
++ * This helper actually implements a subset of **setsockopt()**.
++ * It supports the following *level*\ s:
++ *
++ * * **SOL_SOCKET**, which supports the following *optname*\ s:
++ * **SO_RCVBUF**, **SO_SNDBUF**, **SO_MAX_PACING_RATE**,
++ * **SO_PRIORITY**, **SO_RCVLOWAT**, **SO_MARK**.
++ * * **IPPROTO_TCP**, which supports the following *optname*\ s:
++ * **TCP_CONGESTION**, **TCP_BPF_IW**,
++ * **TCP_BPF_SNDCWND_CLAMP**.
++ * * **IPPROTO_IP**, which supports *optname* **IP_TOS**.
++ * * **IPPROTO_IPV6**, which supports *optname* **IPV6_TCLASS**.
++ * Return
++ * 0 on success, or a negative error in case of failure.
++ *
++ * int bpf_skb_adjust_room(struct sk_buff *skb, s32 len_diff, u32 mode, u64 flags)
++ * Description
++ * Grow or shrink the room for data in the packet associated to
++ * *skb* by *len_diff*, and according to the selected *mode*.
++ *
++ * There is a single supported mode at this time:
++ *
++ * * **BPF_ADJ_ROOM_NET**: Adjust room at the network layer
++ * (room space is added or removed below the layer 3 header).
++ *
++ * All values for *flags* are reserved for future usage, and must
++ * be left at zero.
++ *
++ * A call to this helper is susceptible to change the underlaying
++ * packet buffer. Therefore, at load time, all checks on pointers
++ * previously done by the verifier are invalidated and must be
++ * performed again, if the helper is used in combination with
++ * direct packet access.
++ * Return
++ * 0 on success, or a negative error in case of failure.
++ *
++ * int bpf_redirect_map(struct bpf_map *map, u32 key, u64 flags)
++ * Description
++ * Redirect the packet to the endpoint referenced by *map* at
++ * index *key*. Depending on its type, this *map* can contain
++ * references to net devices (for forwarding packets through other
++ * ports), or to CPUs (for redirecting XDP frames to another CPU;
++ * but this is only implemented for native XDP (with driver
++ * support) as of this writing).
++ *
++ * All values for *flags* are reserved for future usage, and must
++ * be left at zero.
++ *
++ * When used to redirect packets to net devices, this helper
++ * provides a high performance increase over **bpf_redirect**\ ().
++ * This is due to various implementation details of the underlying
++ * mechanisms, one of which is the fact that **bpf_redirect_map**\
++ * () tries to send packet as a "bulk" to the device.
++ * Return
++ * **XDP_REDIRECT** on success, or **XDP_ABORTED** on error.
++ *
++ * int bpf_sk_redirect_map(struct bpf_map *map, u32 key, u64 flags)
++ * Description
++ * Redirect the packet to the socket referenced by *map* (of type
++ * **BPF_MAP_TYPE_SOCKMAP**) at index *key*. Both ingress and
++ * egress interfaces can be used for redirection. The
++ * **BPF_F_INGRESS** value in *flags* is used to make the
++ * distinction (ingress path is selected if the flag is present,
++ * egress path otherwise). This is the only flag supported for now.
++ * Return
++ * **SK_PASS** on success, or **SK_DROP** on error.
++ *
++ * int bpf_sock_map_update(struct bpf_sock_ops *skops, struct bpf_map *map, void *key, u64 flags)
++ * Description
++ * Add an entry to, or update a *map* referencing sockets. The
++ * *skops* is used as a new value for the entry associated to
++ * *key*. *flags* is one of:
++ *
++ * **BPF_NOEXIST**
++ * The entry for *key* must not exist in the map.
++ * **BPF_EXIST**
++ * The entry for *key* must already exist in the map.
++ * **BPF_ANY**
++ * No condition on the existence of the entry for *key*.
++ *
++ * If the *map* has eBPF programs (parser and verdict), those will
++ * be inherited by the socket being added. If the socket is
++ * already attached to eBPF programs, this results in an error.
++ * Return
++ * 0 on success, or a negative error in case of failure.
++ *
++ * int bpf_xdp_adjust_meta(struct xdp_buff *xdp_md, int delta)
++ * Description
++ * Adjust the address pointed by *xdp_md*\ **->data_meta** by
++ * *delta* (which can be positive or negative). Note that this
++ * operation modifies the address stored in *xdp_md*\ **->data**,
++ * so the latter must be loaded only after the helper has been
++ * called.
++ *
++ * The use of *xdp_md*\ **->data_meta** is optional and programs
++ * are not required to use it. The rationale is that when the
++ * packet is processed with XDP (e.g. as DoS filter), it is
++ * possible to push further meta data along with it before passing
++ * to the stack, and to give the guarantee that an ingress eBPF
++ * program attached as a TC classifier on the same device can pick
++ * this up for further post-processing. Since TC works with socket
++ * buffers, it remains possible to set from XDP the **mark** or
++ * **priority** pointers, or other pointers for the socket buffer.
++ * Having this scratch space generic and programmable allows for
++ * more flexibility as the user is free to store whatever meta
++ * data they need.
++ *
++ * A call to this helper is susceptible to change the underlaying
++ * packet buffer. Therefore, at load time, all checks on pointers
++ * previously done by the verifier are invalidated and must be
++ * performed again, if the helper is used in combination with
++ * direct packet access.
++ * Return
++ * 0 on success, or a negative error in case of failure.
++ *
++ * int bpf_perf_event_read_value(struct bpf_map *map, u64 flags, struct bpf_perf_event_value *buf, u32 buf_size)
++ * Description
++ * Read the value of a perf event counter, and store it into *buf*
++ * of size *buf_size*. This helper relies on a *map* of type
++ * **BPF_MAP_TYPE_PERF_EVENT_ARRAY**. The nature of the perf event
++ * counter is selected when *map* is updated with perf event file
++ * descriptors. The *map* is an array whose size is the number of
++ * available CPUs, and each cell contains a value relative to one
++ * CPU. The value to retrieve is indicated by *flags*, that
++ * contains the index of the CPU to look up, masked with
++ * **BPF_F_INDEX_MASK**. Alternatively, *flags* can be set to
++ * **BPF_F_CURRENT_CPU** to indicate that the value for the
++ * current CPU should be retrieved.
++ *
++ * This helper behaves in a way close to
++ * **bpf_perf_event_read**\ () helper, save that instead of
++ * just returning the value observed, it fills the *buf*
++ * structure. This allows for additional data to be retrieved: in
++ * particular, the enabled and running times (in *buf*\
++ * **->enabled** and *buf*\ **->running**, respectively) are
++ * copied. In general, **bpf_perf_event_read_value**\ () is
++ * recommended over **bpf_perf_event_read**\ (), which has some
++ * ABI issues and provides fewer functionalities.
++ *
++ * These values are interesting, because hardware PMU (Performance
++ * Monitoring Unit) counters are limited resources. When there are
++ * more PMU based perf events opened than available counters,
++ * kernel will multiplex these events so each event gets certain
++ * percentage (but not all) of the PMU time. In case that
++ * multiplexing happens, the number of samples or counter value
++ * will not reflect the case compared to when no multiplexing
++ * occurs. This makes comparison between different runs difficult.
++ * Typically, the counter value should be normalized before
++ * comparing to other experiments. The usual normalization is done
++ * as follows.
++ *
++ * ::
++ *
++ * normalized_counter = counter * t_enabled / t_running
++ *
++ * Where t_enabled is the time enabled for event and t_running is
++ * the time running for event since last normalization. The
++ * enabled and running times are accumulated since the perf event
++ * open. To achieve scaling factor between two invocations of an
++ * eBPF program, users can can use CPU id as the key (which is
++ * typical for perf array usage model) to remember the previous
++ * value and do the calculation inside the eBPF program.
++ * Return
++ * 0 on success, or a negative error in case of failure.
++ *
++ * int bpf_perf_prog_read_value(struct bpf_perf_event_data *ctx, struct bpf_perf_event_value *buf, u32 buf_size)
++ * Description
++ * For en eBPF program attached to a perf event, retrieve the
++ * value of the event counter associated to *ctx* and store it in
++ * the structure pointed by *buf* and of size *buf_size*. Enabled
++ * and running times are also stored in the structure (see
++ * description of helper **bpf_perf_event_read_value**\ () for
++ * more details).
++ * Return
++ * 0 on success, or a negative error in case of failure.
++ *
++ * int bpf_getsockopt(struct bpf_sock_ops *bpf_socket, int level, int optname, char *optval, int optlen)
++ * Description
++ * Emulate a call to **getsockopt()** on the socket associated to
++ * *bpf_socket*, which must be a full socket. The *level* at
++ * which the option resides and the name *optname* of the option
++ * must be specified, see **getsockopt(2)** for more information.
++ * The retrieved value is stored in the structure pointed by
++ * *opval* and of length *optlen*.
++ *
++ * This helper actually implements a subset of **getsockopt()**.
++ * It supports the following *level*\ s:
++ *
++ * * **IPPROTO_TCP**, which supports *optname*
++ * **TCP_CONGESTION**.
++ * * **IPPROTO_IP**, which supports *optname* **IP_TOS**.
++ * * **IPPROTO_IPV6**, which supports *optname* **IPV6_TCLASS**.
++ * Return
++ * 0 on success, or a negative error in case of failure.
++ *
++ * int bpf_override_return(struct pt_reg *regs, u64 rc)
++ * Description
++ * Used for error injection, this helper uses kprobes to override
++ * the return value of the probed function, and to set it to *rc*.
++ * The first argument is the context *regs* on which the kprobe
++ * works.
++ *
++ * This helper works by setting setting the PC (program counter)
++ * to an override function which is run in place of the original
++ * probed function. This means the probed function is not run at
++ * all. The replacement function just returns with the required
++ * value.
++ *
++ * This helper has security implications, and thus is subject to
++ * restrictions. It is only available if the kernel was compiled
++ * with the **CONFIG_BPF_KPROBE_OVERRIDE** configuration
++ * option, and in this case it only works on functions tagged with
++ * **ALLOW_ERROR_INJECTION** in the kernel code.
++ *
++ * Also, the helper is only available for the architectures having
++ * the CONFIG_FUNCTION_ERROR_INJECTION option. As of this writing,
++ * x86 architecture is the only one to support this feature.
++ * Return
++ * 0
++ *
++ * int bpf_sock_ops_cb_flags_set(struct bpf_sock_ops *bpf_sock, int argval)
++ * Description
++ * Attempt to set the value of the **bpf_sock_ops_cb_flags** field
++ * for the full TCP socket associated to *bpf_sock_ops* to
++ * *argval*.
++ *
++ * The primary use of this field is to determine if there should
++ * be calls to eBPF programs of type
++ * **BPF_PROG_TYPE_SOCK_OPS** at various points in the TCP
++ * code. A program of the same type can change its value, per
++ * connection and as necessary, when the connection is
++ * established. This field is directly accessible for reading, but
++ * this helper must be used for updates in order to return an
++ * error if an eBPF program tries to set a callback that is not
++ * supported in the current kernel.
++ *
++ * The supported callback values that *argval* can combine are:
++ *
++ * * **BPF_SOCK_OPS_RTO_CB_FLAG** (retransmission time out)
++ * * **BPF_SOCK_OPS_RETRANS_CB_FLAG** (retransmission)
++ * * **BPF_SOCK_OPS_STATE_CB_FLAG** (TCP state change)
++ *
++ * Here are some examples of where one could call such eBPF
++ * program:
++ *
++ * * When RTO fires.
++ * * When a packet is retransmitted.
++ * * When the connection terminates.
++ * * When a packet is sent.
++ * * When a packet is received.
++ * Return

++ *
++ * int bpf_msg_redirect_map(struct sk_msg_buff *msg, struct bpf_map *map, u32 key, u64 flags)
++ * Description
++ * This helper is used in programs implementing policies at the
++ * socket level. If the message *msg* is allowed to pass (i.e. if
++ * the verdict eBPF program returns **SK_PASS**), redirect it to
++ * the socket referenced by *map* (of type
++ * **BPF_MAP_TYPE_SOCKMAP**) at index *key*. Both ingress and
++ * egress interfaces can be used for redirection. The
++ * **BPF_F_INGRESS** value in *flags* is used to make the
++ * distinction (ingress path is selected if the flag is present,
++ * egress path otherwise). This is the only flag supported for now.
++ * Return
++ * **SK_PASS** on success, or **SK_DROP** on error.
++ *
++ * int bpf_msg_apply_bytes(struct sk_msg_buff *msg, u32 bytes)
++ * Description
++ * For socket policies, apply the verdict of the eBPF program to
++ * the next *bytes* (number of bytes) of message *msg*.
++ *
++ * For example, this helper can be used in the following cases:
++ *
++ * * A single **sendmsg**\ () or **sendfile**\ () system call
++ * contains multiple logical messages that the eBPF program is
++ * supposed to read and for which it should apply a verdict.
++ * * An eBPF program only cares to read the first *bytes* of a
++ * *msg*. If the message has a large payload, then setting up
++ * and calling the eBPF program repeatedly for all bytes, even
++ * though the verdict is already known, would create unnecessary
++ * overhead.
++ *
++ * When called from within an eBPF program, the helper sets a
++ * counter internal to the BPF infrastructure, that is used to
++ * apply the last verdict to the next *bytes*. If *bytes* is
++ * smaller than the current data being processed from a
++ * **sendmsg**\ () or **sendfile**\ () system call, the first
++ * *bytes* will be sent and the eBPF program will be re-run with
++ * the pointer for start of data pointing to byte number *bytes*
++ * **+ 1**. If *bytes* is larger than the current data being
++ * processed, then the eBPF verdict will be applied to multiple
++ * **sendmsg**\ () or **sendfile**\ () calls until *bytes* are
++ * consumed.
++ *
++ * Note that if a socket closes with the internal counter holding
++ * a non-zero value, this is not a problem because data is not
++ * being buffered for *bytes* and is sent as it is received.
++ * Return
++ * 0
++ *
++ * int bpf_msg_cork_bytes(struct sk_msg_buff *msg, u32 bytes)
++ * Description
++ * For socket policies, prevent the execution of the verdict eBPF
++ * program for message *msg* until *bytes* (byte number) have been
++ * accumulated.
++ *
++ * This can be used when one needs a specific number of bytes
++ * before a verdict can be assigned, even if the data spans
++ * multiple **sendmsg**\ () or **sendfile**\ () calls. The extreme
++ * case would be a user calling **sendmsg**\ () repeatedly with
++ * 1-byte long message segments. Obviously, this is bad for
++ * performance, but it is still valid. If the eBPF program needs
++ * *bytes* bytes to validate a header, this helper can be used to
++ * prevent the eBPF program to be called again until *bytes* have
++ * been accumulated.
++ * Return
++ * 0
++ *
++ * int bpf_msg_pull_data(struct sk_msg_buff *msg, u32 start, u32 end, u64 flags)
++ * Description
++ * For socket policies, pull in non-linear data from user space
++ * for *msg* and set pointers *msg*\ **->data** and *msg*\
++ * **->data_end** to *start* and *end* bytes offsets into *msg*,
++ * respectively.
++ *
++ * If a program of type **BPF_PROG_TYPE_SK_MSG** is run on a
++ * *msg* it can only parse data that the (**data**, **data_end**)
++ * pointers have already consumed. For **sendmsg**\ () hooks this
++ * is likely the first scatterlist element. But for calls relying
++ * on the **sendpage** handler (e.g. **sendfile**\ ()) this will
++ * be the range (**0**, **0**) because the data is shared with
++ * user space and by default the objective is to avoid allowing
++ * user space to modify data while (or after) eBPF verdict is
++ * being decided. This helper can be used to pull in data and to
++ * set the start and end pointer to given values. Data will be
++ * copied if necessary (i.e. if data was not linear and if start
++ * and end pointers do not point to the same chunk).
++ *
++ * A call to this helper is susceptible to change the underlaying
++ * packet buffer. Therefore, at load time, all checks on pointers
++ * previously done by the verifier are invalidated and must be
++ * performed again, if the helper is used in combination with
++ * direct packet access.
++ *
++ * All values for *flags* are reserved for future usage, and must
++ * be left at zero.
++ * Return
++ * 0 on success, or a negative error in case of failure.
++ *
++ * int bpf_bind(struct bpf_sock_addr *ctx, struct sockaddr *addr, int addr_len)
++ * Description
++ * Bind the socket associated to *ctx* to the address pointed by
++ * *addr*, of length *addr_len*. This allows for making outgoing
++ * connection from the desired IP address, which can be useful for
++ * example when all processes inside a cgroup should use one
++ * single IP address on a host that has multiple IP configured.
++ *
++ * This helper works for IPv4 and IPv6, TCP and UDP sockets. The
++ * domain (*addr*\ **->sa_family**) must be **AF_INET** (or
++ * **AF_INET6**). Looking for a free port to bind to can be
++ * expensive, therefore binding to port is not permitted by the
++ * helper: *addr*\ **->sin_port** (or **sin6_port**, respectively)
++ * must be set to zero.
++ * Return
++ * 0 on success, or a negative error in case of failure.
++ *
++ * int bpf_xdp_adjust_tail(struct xdp_buff *xdp_md, int delta)
++ * Description
++ * Adjust (move) *xdp_md*\ **->data_end** by *delta* bytes. It is
++ * only possible to shrink the packet as of this writing,
++ * therefore *delta* must be a negative integer.
++ *
++ * A call to this helper is susceptible to change the underlaying
++ * packet buffer. Therefore, at load time, all checks on pointers
++ * previously done by the verifier are invalidated and must be
++ * performed again, if the helper is used in combination with
++ * direct packet access.
++ * Return
++ * 0 on success, or a negative error in case of failure.
++ *
++ * int bpf_skb_get_xfrm_state(struct sk_buff *skb, u32 index, struct bpf_xfrm_state *xfrm_state, u32 size, u64 flags)
++ * Description
++ * Retrieve the XFRM state (IP transform framework, see also
++ * **ip-xfrm(8)**) at *index* in XFRM "security path" for *skb*.
++ *
++ * The retrieved value is stored in the **struct bpf_xfrm_state**
++ * pointed by *xfrm_state* and of length *size*.
++ *
++ * All values for *flags* are reserved for future usage, and must
++ * be left at zero.
++ *
++ * This helper is available only if the kernel was compiled with
++ * **CONFIG_XFRM** configuration option.
++ * Return
++ * 0 on success, or a negative error in case of failure.
++ *
++ * int bpf_get_stack(struct pt_regs *regs, void *buf, u32 size, u64 flags)
++ * Description
++ * Return a user or a kernel stack in bpf program provided buffer.
++ * To achieve this, the helper needs *ctx*, which is a pointer
++ * to the context on which the tracing program is executed.
++ * To store the stacktrace, the bpf program provides *buf* with
++ * a nonnegative *size*.
++ *
++ * The last argument, *flags*, holds the number of stack frames to
++ * skip (from 0 to 255), masked with
++ * **BPF_F_SKIP_FIELD_MASK**. The next bits can be used to set
++ * the following flags:
++ *
++ * **BPF_F_USER_STACK**
++ * Collect a user space stack instead of a kernel stack.
++ * **BPF_F_USER_BUILD_ID**
++ * Collect buildid+offset instead of ips for user stack,
++ * only valid if **BPF_F_USER_STACK** is also specified.
++ *
++ * **bpf_get_stack**\ () can collect up to
++ * **PERF_MAX_STACK_DEPTH** both kernel and user frames, subject
++ * to sufficient large buffer size. Note that
++ * this limit can be controlled with the **sysctl** program, and
++ * that it should be manually increased in order to profile long
++ * user stacks (such as stacks for Java programs). To do so, use:
++ *
++ * ::
++ *
++ * # sysctl kernel.perf_event_max_stack=<new value>
++ * Return
++ * A non-negative value equal to or less than *size* on success,
++ * or a negative error in case of failure.
++ *
++ * int bpf_skb_load_bytes_relative(const struct sk_buff *skb, u32 offset, void *to, u32 len, u32 start_header)
++ * Description
++ * This helper is similar to **bpf_skb_load_bytes**\ () in that
++ * it provides an easy way to load *len* bytes from *offset*
++ * from the packet associated to *skb*, into the buffer pointed
++ * by *to*. The difference to **bpf_skb_load_bytes**\ () is that
++ * a fifth argument *start_header* exists in order to select a
++ * base offset to start from. *start_header* can be one of:
++ *
++ * **BPF_HDR_START_MAC**
++ * Base offset to load data from is *skb*'s mac header.
++ * **BPF_HDR_START_NET**
++ * Base offset to load data from is *skb*'s network header.
++ *
++ * In general, "direct packet access" is the preferred method to
++ * access packet data, however, this helper is in particular useful
++ * in socket filters where *skb*\ **->data** does not always point
++ * to the start of the mac header and where "direct packet access"
++ * is not available.
++ * Return
++ * 0 on success, or a negative error in case of failure.
++ *
++ * int bpf_fib_lookup(void *ctx, struct bpf_fib_lookup *params, int plen, u32 flags)
++ * Description
++ * Do FIB lookup in kernel tables using parameters in *params*.
++ * If lookup is successful and result shows packet is to be
++ * forwarded, the neighbor tables are searched for the nexthop.
++ * If successful (ie., FIB lookup shows forwarding and nexthop
++ * is resolved), the nexthop address is returned in ipv4_dst
++ * or ipv6_dst based on family, smac is set to mac address of
++ * egress device, dmac is set to nexthop mac address, rt_metric
++ * is set to metric from route (IPv4/IPv6 only), and ifindex
++ * is set to the device index of the nexthop from the FIB lookup.
++ *
++ * *plen* argument is the size of the passed in struct.
++ * *flags* argument can be a combination of one or more of the
++ * following values:
++ *
++ * **BPF_FIB_LOOKUP_DIRECT**
++ * Do a direct table lookup vs full lookup using FIB
++ * rules.
++ * **BPF_FIB_LOOKUP_OUTPUT**
++ * Perform lookup from an egress perspective (default is
++ * ingress).
++ *
++ * *ctx* is either **struct xdp_md** for XDP programs or
++ * **struct sk_buff** tc cls_act programs.
++ * Return
++ * * < 0 if any input argument is invalid
++ * * 0 on success (packet is forwarded, nexthop neighbor exists)
++ * * > 0 one of **BPF_FIB_LKUP_RET_** codes explaining why the
++ * packet is not forwarded or needs assist from full stack
++ *
++ * int bpf_sock_hash_update(struct bpf_sock_ops_kern *skops, struct bpf_map *map, void *key, u64 flags)
++ * Description
++ * Add an entry to, or update a sockhash *map* referencing sockets.
++ * The *skops* is used as a new value for the entry associated to
++ * *key*. *flags* is one of:
++ *
++ * **BPF_NOEXIST**
++ * The entry for *key* must not exist in the map.
++ * **BPF_EXIST**
++ * The entry for *key* must already exist in the map.
++ * **BPF_ANY**
++ * No condition on the existence of the entry for *key*.
++ *
++ * If the *map* has eBPF programs (parser and verdict), those will
++ * be inherited by the socket being added. If the socket is
++ * already attached to eBPF programs, this results in an error.
++ * Return
++ * 0 on success, or a negative error in case of failure.
++ *
++ * int bpf_msg_redirect_hash(struct sk_msg_buff *msg, struct bpf_map *map, void *key, u64 flags)
++ * Description
++ * This helper is used in programs implementing policies at the
++ * socket level. If the message *msg* is allowed to pass (i.e. if
++ * the verdict eBPF program returns **SK_PASS**), redirect it to
++ * the socket referenced by *map* (of type
++ * **BPF_MAP_TYPE_SOCKHASH**) using hash *key*. Both ingress and
++ * egress interfaces can be used for redirection. The
++ * **BPF_F_INGRESS** value in *flags* is used to make the
++ * distinction (ingress path is selected if the flag is present,
++ * egress path otherwise). This is the only flag supported for now.
++ * Return
++ * **SK_PASS** on success, or **SK_DROP** on error.
++ *
++ * int bpf_sk_redirect_hash(struct sk_buff *skb, struct bpf_map *map, void *key, u64 flags)
++ * Description
++ * This helper is used in programs implementing policies at the
++ * skb socket level. If the sk_buff *skb* is allowed to pass (i.e.
++ * if the verdeict eBPF program returns **SK_PASS**), redirect it
++ * to the socket referenced by *map* (of type
++ * **BPF_MAP_TYPE_SOCKHASH**) using hash *key*. Both ingress and
++ * egress interfaces can be used for redirection. The
++ * **BPF_F_INGRESS** value in *flags* is used to make the
++ * distinction (ingress path is selected if the flag is present,
++ * egress otherwise). This is the only flag supported for now.
++ * Return
++ * **SK_PASS** on success, or **SK_DROP** on error.
++ *
++ * int bpf_lwt_push_encap(struct sk_buff *skb, u32 type, void *hdr, u32 len)
++ * Description
++ * Encapsulate the packet associated to *skb* within a Layer 3
++ * protocol header. This header is provided in the buffer at
++ * address *hdr*, with *len* its size in bytes. *type* indicates
++ * the protocol of the header and can be one of:
++ *
++ * **BPF_LWT_ENCAP_SEG6**
++ * IPv6 encapsulation with Segment Routing Header
++ * (**struct ipv6_sr_hdr**). *hdr* only contains the SRH,
++ * the IPv6 header is computed by the kernel.
++ * **BPF_LWT_ENCAP_SEG6_INLINE**
++ * Only works if *skb* contains an IPv6 packet. Insert a
++ * Segment Routing Header (**struct ipv6_sr_hdr**) inside
++ * the IPv6 header.
++ *
++ * A call to this helper is susceptible to change the underlaying
++ * packet buffer. Therefore, at load time, all checks on pointers
++ * previously done by the verifier are invalidated and must be
++ * performed again, if the helper is used in combination with
++ * direct packet access.
++ * Return
++ * 0 on success, or a negative error in case of failure.
++ *
++ * int bpf_lwt_seg6_store_bytes(struct sk_buff *skb, u32 offset, const void *from, u32 len)
++ * Description
++ * Store *len* bytes from address *from* into the packet
++ * associated to *skb*, at *offset*. Only the flags, tag and TLVs
++ * inside the outermost IPv6 Segment Routing Header can be
++ * modified through this helper.
++ *
++ * A call to this helper is susceptible to change the underlaying
++ * packet buffer. Therefore, at load time, all checks on pointers

++ * Description
++ * Adjust the size allocated to TLVs in the outermost IPv6
++ * Segment Routing Header contained in the packet associated to
++ * *skb*, at position *offset* by *delta* bytes. Only offsets
++ * after the segments are accepted. *delta* can be as well
++ * positive (growing) as negative (shrinking).
++ *
++ * A call to this helper is susceptible to change the underlaying
++ * packet buffer. Therefore, at load time, all checks on pointers
++ * previously done by the verifier are invalidated and must be

++ * Description
++ * Apply an IPv6 Segment Routing action of type *action* to the
++ * packet associated to *skb*. Each action takes a parameter
++ * contained at address *param*, and of length *param_len* bytes.
++ * *action* can be one of:
++ *
++ * **SEG6_LOCAL_ACTION_END_X**
++ * End.X action: Endpoint with Layer-3 cross-connect.

++ * **SEG6_LOCAL_ACTION_END_B6_ENCAP**
++ * End.B6.Encap action: Endpoint bound to an SRv6
++ * encapsulation policy.
++ * Type of param: **struct ipv6_sr_hdr**.
++ *
++ * A call to this helper is susceptible to change the underlaying

++ * Return
++ * 0 on success, or a negative error in case of failure.
++ *
++ * int bpf_rc_keydown(void *ctx, u32 protocol, u64 scancode, u32 toggle)
++ * Description
++ * This helper is used in programs implementing IR decoding, to
++ * report a successfully decoded key press with *scancode*,
++ * *toggle* value in the given *protocol*. The scancode will be
++ * translated to a keycode using the rc keymap, and reported as
++ * an input key down event. After a period a key up event is
++ * generated. This period can be extended by calling either
++ * **bpf_rc_keydown**\ () again with the same values, or calling
++ * **bpf_rc_repeat**\ ().
++ *
++ * Some protocols include a toggle bit, in case the button was
++ * released and pressed again between consecutive scancodes.
++ *
++ * The *ctx* should point to the lirc sample as passed into
++ * the program.
++ *
++ * The *protocol* is the decoded protocol number (see
++ * **enum rc_proto** for some predefined values).
++ *
++ * This helper is only available is the kernel was compiled with
++ * the **CONFIG_BPF_LIRC_MODE2** configuration option set to
++ * "**y**".
++ * Return
++ * 0
++ *
++ * int bpf_rc_repeat(void *ctx)
++ * Description
++ * This helper is used in programs implementing IR decoding, to
++ * report a successfully decoded repeat key message. This delays
++ * the generation of a key up event for previously generated
++ * key down event.
++ *
++ * Some IR protocols like NEC have a special IR message for
++ * repeating last button, for when a button is held down.
++ *
++ * The *ctx* should point to the lirc sample as passed into
++ * the program.
++ *
++ * This helper is only available is the kernel was compiled with
++ * the **CONFIG_BPF_LIRC_MODE2** configuration option set to
++ * "**y**".
++ * Return
++ * 0
++ *
++ * uint64_t bpf_skb_cgroup_id(struct sk_buff *skb)
++ * Description
++ * Return the cgroup v2 id of the socket associated with the *skb*.
++ * This is roughly similar to the **bpf_get_cgroup_classid**\ ()
++ * helper for cgroup v1 by providing a tag resp. identifier that
++ * can be matched on or used for map lookups e.g. to implement
++ * policy. The cgroup v2 id of a given path in the hierarchy is
++ * exposed in user space through the f_handle API in order to get
++ * to the same 64-bit id.
++ *
++ * This helper can be used on TC egress path, but not on ingress,
++ * and is available only if the kernel was compiled with the
++ * **CONFIG_SOCK_CGROUP_DATA** configuration option.
++ * Return
++ * The id is returned or 0 in case the id could not be retrieved.
++ *
++ * u64 bpf_skb_ancestor_cgroup_id(struct sk_buff *skb, int ancestor_level)
++ * Description
++ * Return id of cgroup v2 that is ancestor of cgroup associated
++ * with the *skb* at the *ancestor_level*. The root cgroup is at
++ * *ancestor_level* zero and each step down the hierarchy
++ * increments the level. If *ancestor_level* == level of cgroup
++ * associated with *skb*, then return value will be same as that
++ * of **bpf_skb_cgroup_id**\ ().
++ *
++ * The helper is useful to implement policies based on cgroups
++ * that are upper in hierarchy than immediate cgroup associated
++ * with *skb*.
++ *
++ * The format of returned id and helper limitations are same as in
++ * **bpf_skb_cgroup_id**\ ().
++ * Return
++ * The id is returned or 0 in case the id could not be retrieved.
++ *
++ * u64 bpf_get_current_cgroup_id(void)
++ * Return
++ * A 64-bit integer containing the current cgroup id based
++ * on the cgroup within which the current task is running.
++ *
++ * void* get_local_storage(void *map, u64 flags)
++ * Description
++ * Get the pointer to the local storage area.
++ * The type and the size of the local storage is defined
++ * by the *map* argument.
++ * The *flags* meaning is specific for each map type,
++ * and has to be 0 for cgroup local storage.
++ *
++ * Depending on the BPF program type, a local storage area
++ * can be shared between multiple instances of the BPF program,
++ * running simultaneously.
++ *
++ * A user should care about the synchronization by himself.
++ * For example, by using the **BPF_STX_XADD** instruction to alter
++ * the shared data.
++ * Return
++ * A pointer to the local storage area.
++ *
++ * int bpf_sk_select_reuseport(struct sk_reuseport_md *reuse, struct bpf_map *map, void *key, u64 flags)
++ * Description
++ * Select a **SO_REUSEPORT** socket from a

++ *
++ * struct bpf_sock *bpf_sk_lookup_tcp(void *ctx, struct bpf_sock_tuple *tuple, u32 tuple_size, u64 netns, u64 flags)
++ * Description
++ * Look for TCP socket matching *tuple*, optionally in a child
++ * network namespace *netns*. The return value must be checked,
++ * and if non-**NULL**, released via **bpf_sk_release**\ ().
++ *
++ * The *ctx* should point to the context of the program, such as
++ * the skb or socket (depending on the hook in use). This is used
++ * to determine the base network namespace for the lookup.
++ *
++ * *tuple_size* must be one of:
++ *
++ * **sizeof**\ (*tuple*\ **->ipv4**)
++ * Look for an IPv4 socket.
++ * **sizeof**\ (*tuple*\ **->ipv6**)
++ * Look for an IPv6 socket.
++ *
++ * If the *netns* is a negative signed 32-bit integer, then the
++ * socket lookup table in the netns associated with the *ctx* will
++ * will be used. For the TC hooks, this is the netns of the device
++ * in the skb. For socket hooks, this is the netns of the socket.
++ * If *netns* is any other signed 32-bit value greater than or
++ * equal to zero then it specifies the ID of the netns relative to
++ * the netns associated with the *ctx*. *netns* values beyond the
++ * range of 32-bit integers are reserved for future use.
++ *
++ * All values for *flags* are reserved for future usage, and must
++ * be left at zero.
++ *
++ * This helper is available only if the kernel was compiled with
++ * **CONFIG_NET** configuration option.
++ * Return
++ * Pointer to **struct bpf_sock**, or **NULL** in case of failure.

++ * network namespace *netns*. The return value must be checked,
++ * and if non-**NULL**, released via **bpf_sk_release**\ ().
++ *
++ * The *ctx* should point to the context of the program, such as

++ * *tuple_size* must be one of:
++ *
++ * **sizeof**\ (*tuple*\ **->ipv4**)
++ * Look for an IPv4 socket.
++ * **sizeof**\ (*tuple*\ **->ipv6**)
++ * Look for an IPv6 socket.
++ *
++ * If the *netns* is a negative signed 32-bit integer, then the

++ * int bpf_msg_push_data(struct sk_buff *skb, u32 start, u32 len, u64 flags)
++ * Description
++ * For socket policies, insert *len* bytes into *msg* at offset
++ * *start*.
++ *
++ * If a program of type **BPF_PROG_TYPE_SK_MSG** is run on a
++ * *msg* it may want to insert metadata or options into the *msg*.
++ * This can later be read and used by any of the lower layer BPF
++ * hooks.
++ *
++ * This helper may fail if under memory pressure (a malloc
++ * fails) in these cases BPF programs will get an appropriate
++ * error and BPF programs will need to handle them.
++ * Return
++ * 0 on success, or a negative error in case of failure.
++ *
++ * int bpf_msg_pop_data(struct sk_msg_buff *msg, u32 start, u32 pop, u64 flags)
++ * Description
++ * Will remove *pop* bytes from a *msg* starting at byte *start*.
++ * This may result in **ENOMEM** errors under certain situations if
++ * an allocation and copy are required due to a full ring buffer.
++ * However, the helper will try to avoid doing the allocation
++ * if possible. Other errors can occur if input parameters are
++ * invalid either due to *start* byte not being valid part of *msg*
++ * payload and/or *pop* value being to large.
++ * Return
++ * 0 on success, or a negative error in case of failure.
++ *
++ * int bpf_rc_pointer_rel(void *ctx, s32 rel_x, s32 rel_y)
++ * Description
++ * This helper is used in programs implementing IR decoding, to
++ * report a successfully decoded pointer movement.
++ *
++ * The *ctx* should point to the lirc sample as passed into
++ * the program.
++ *
++ * This helper is only available is the kernel was compiled with
++ * the **CONFIG_BPF_LIRC_MODE2** configuration option set to
++ * "**y**".
++ * Return
++ * 0

++ * A traditional ioctl interface for the device mapper.
++ *
++ * Each device can have two tables associated with it, an
++ * 'active' table which is the one currently used by io passing
++ * through the device, and an 'inactive' one which is a table
++ * that is being prepared as a replacement for the 'active' one.
++ *
++ * DM_VERSION:
++ * Just get the version information for the ioctl interface.
++ *
++ * DM_REMOVE_ALL:
++ * Remove all dm devices, destroy all tables. Only really used
++ * for debug.
++ *
++ * DM_LIST_DEVICES:
++ * Get a list of all the dm device names.
++ *
++ * DM_DEV_CREATE:
++ * Create a new device, neither the 'active' or 'inactive' table
++ * slots will be filled. The device will be in suspended state
++ * after creation, however any io to the device will get errored
++ * since it will be out-of-bounds.
++ *
++ * DM_DEV_REMOVE:
++ * Remove a device, destroy any tables.
++ *
++ * DM_DEV_RENAME:
++ * Rename a device or set its uuid if none was previously supplied.
++ *
++ * DM_SUSPEND:
++ * This performs both suspend and resume, depending which flag is
++ * passed in.
++ * Suspend: This command will not return until all pending io to
++ * the device has completed. Further io will be deferred until
++ * the device is resumed.
++ * Resume: It is no longer an error to issue this command on an
++ * unsuspended device. If a table is present in the 'inactive'
++ * slot, it will be moved to the active slot, then the old table
++ * from the active slot will be _destroyed_. Finally the device
++ * is resumed.
++ *
++ * DM_DEV_STATUS:
++ * Retrieves the status for the table in the 'active' slot.
++ *
++ * DM_DEV_WAIT:

++ * struct ethtool_cmd - DEPRECATED, link control and status
++ * This structure is DEPRECATED, please use struct ethtool_link_settings.
++ * @cmd: Command number = %ETHTOOL_GSET or %ETHTOOL_SSET
++ * @supported: Bitmask of %SUPPORTED_* flags for the link modes,
++ * physical connectors and other link features for which the
++ * interface supports autonegotiation or auto-detection.
++ * Read-only.
++ * @advertising: Bitmask of %ADVERTISED_* flags for the link modes,
++ * physical connectors and other link features that are
++ * advertised through autonegotiation or enabled for
++ * auto-detection.
++ * @speed: Low bits of the speed, 1Mb units, 0 to INT_MAX or SPEED_UNKNOWN
++ * @duplex: Duplex mode; one of %DUPLEX_*
++ * @port: Physical connector type; one of %PORT_*
++ * @phy_address: MDIO address of PHY (transceiver); 0 or 255 if not
++ * applicable. For clause 45 PHYs this is the PRTAD.
++ * @transceiver: Historically used to distinguish different possible
++ * PHY types, but not in a consistent way. Deprecated.
++ * @autoneg: Enable/disable autonegotiation and auto-detection;
++ * either %AUTONEG_DISABLE or %AUTONEG_ENABLE
++ * @mdio_support: Bitmask of %ETH_MDIO_SUPPORTS_* flags for the MDIO
++ * protocols supported by the interface; 0 if unknown.
++ * Read-only.
++ * @maxtxpkt: Historically used to report TX IRQ coalescing; now
++ * obsoleted by &struct ethtool_coalesce. Read-only; deprecated.
++ * @maxrxpkt: Historically used to report RX IRQ coalescing; now
++ * obsoleted by &struct ethtool_coalesce. Read-only; deprecated.
++ * @speed_hi: High bits of the speed, 1Mb units, 0 to INT_MAX or SPEED_UNKNOWN
++ * @eth_tp_mdix: Ethernet twisted-pair MDI(-X) status; one of
++ * %ETH_TP_MDI_*. If the status is unknown or not applicable, the
++ * value will be %ETH_TP_MDI_INVALID. Read-only.
++ * @eth_tp_mdix_ctrl: Ethernet twisted pair MDI(-X) control; one of
++ * %ETH_TP_MDI_*. If MDI(-X) control is not implemented, reads
++ * yield %ETH_TP_MDI_INVALID and writes may be ignored or rejected.
++ * When written successfully, the link should be renegotiated if
++ * necessary.
++ * @lp_advertising: Bitmask of %ADVERTISED_* flags for the link modes
++ * and other link features that the link partner advertised
++ * through autonegotiation; 0 if unknown or not applicable.
++ * Read-only.
++ *
++ * The link speed in Mbps is split between @speed and @speed_hi. Use
++ * the ethtool_cmd_speed() and ethtool_cmd_speed_set() functions to
++ * access it.
++ *
++ * If autonegotiation is disabled, the speed and @duplex represent the
++ * fixed link mode and are writable if the driver supports multiple
++ * link modes. If it is enabled then they are read-only; if the link
++ * is up they represent the negotiated link mode; if the link is down,
++ * the speed is 0, %SPEED_UNKNOWN or the highest enabled speed and
++ * @duplex is %DUPLEX_UNKNOWN or the best enabled duplex mode.
++ *
++ * Some hardware interfaces may have multiple PHYs and/or physical
++ * connectors fitted or do not allow the driver to detect which are
++ * fitted. For these interfaces @port and/or @phy_address may be
++ * writable, possibly dependent on @autoneg being %AUTONEG_DISABLE.
++ * Otherwise, attempts to write different values may be ignored or
++ * rejected.
++ *
++ * Users should assume that all fields not marked read-only are
++ * writable and subject to validation by the driver. They should use
++ * %ETHTOOL_GSET to get the current values before making specific
++ * changes and then applying them with %ETHTOOL_SSET.
++ *
++ * Deprecated fields should be ignored by both users and drivers.

++ * struct ethtool_coalesce - coalescing parameters for IRQs and stats updates
++ * @cmd: ETHTOOL_{G,S}COALESCE
++ * @rx_coalesce_usecs: How many usecs to delay an RX interrupt after

++ * @rx_max_coalesced_frames: Maximum number of packets to receive

++ * @rx_max_coalesced_frames_irq: Same as @rx_max_coalesced_frames,
++ * except that this value applies while an IRQ is being serviced
++ * by the host.
++ * @tx_coalesce_usecs: How many usecs to delay a TX interrupt after
++ * a packet is sent.
++ * @tx_max_coalesced_frames: Maximum number of packets to be sent
++ * before a TX interrupt.
++ * @tx_coalesce_usecs_irq: Same as @tx_coalesce_usecs, except that
++ * this value applies while an IRQ is being serviced by the host.
++ * @tx_max_coalesced_frames_irq: Same as @tx_max_coalesced_frames,
++ * except that this value applies while an IRQ is being serviced
++ * by the host.
++ * @stats_block_coalesce_usecs: How many usecs to delay in-memory
++ * statistics block updates. Some drivers do not have an
++ * in-memory statistic block, and in such cases this value is
++ * ignored. This value must not be zero.
++ * @use_adaptive_rx_coalesce: Enable adaptive RX coalescing.
++ * @use_adaptive_tx_coalesce: Enable adaptive TX coalescing.
++ * @pkt_rate_low: Threshold for low packet rate (packets per second).
++ * @rx_coalesce_usecs_low: How many usecs to delay an RX interrupt after
++ * a packet arrives, when the packet rate is below @pkt_rate_low.
++ * @rx_max_coalesced_frames_low: Maximum number of packets to be received
++ * before an RX interrupt, when the packet rate is below @pkt_rate_low.
++ * @tx_coalesce_usecs_low: How many usecs to delay a TX interrupt after
++ * a packet is sent, when the packet rate is below @pkt_rate_low.
++ * @tx_max_coalesced_frames_low: Maximum nuumber of packets to be sent before
++ * a TX interrupt, when the packet rate is below @pkt_rate_low.
++ * @pkt_rate_high: Threshold for high packet rate (packets per second).
++ * @rx_coalesce_usecs_high: How many usecs to delay an RX interrupt after
++ * a packet arrives, when the packet rate is above @pkt_rate_high.
++ * @rx_max_coalesced_frames_high: Maximum number of packets to be received
++ * before an RX interrupt, when the packet rate is above @pkt_rate_high.
++ * @tx_coalesce_usecs_high: How many usecs to delay a TX interrupt after
++ * a packet is sent, when the packet rate is above @pkt_rate_high.
++ * @tx_max_coalesced_frames_high: Maximum number of packets to be sent before
++ * a TX interrupt, when the packet rate is above @pkt_rate_high.
++ * @rate_sample_interval: How often to do adaptive coalescing packet rate
++ * sampling, measured in seconds. Must not be zero.
++ *
++ * Each pair of (usecs, max_frames) fields specifies that interrupts
++ * should be coalesced until
++ * (usecs > 0 && time_since_first_completion >= usecs) ||
++ * (max_frames > 0 && completed_frames >= max_frames)
++ *
++ * It is illegal to set both usecs and max_frames to zero as this
++ * would cause interrupts to never be generated. To disable
++ * coalescing, set usecs = 0 and max_frames = 1.
++ *
++ * Some implementations ignore the value of max_frames and use the
++ * condition time_since_first_completion >= usecs
++ *
++ * This is deprecated. Drivers for hardware that does not support
++ * counting completions should validate that max_frames == !rx_usecs.
++ *
++ * Adaptive RX/TX coalescing is an algorithm implemented by some
++ * drivers to improve latency under low packet rates and improve
++ * throughput under high packet rates. Some drivers only implement
++ * one of RX or TX adaptive coalescing. Anything not implemented by
++ * the driver causes these values to be silently ignored.
++ *
++ * When the packet rate is below @pkt_rate_high but above
++ * @pkt_rate_low (both measured in packets per second) the
++ * normal {rx,tx}_* coalescing parameters are used.

++ *
++ * IMPORTANT, Backward compatibility notice: When implementing new

++ * if it succeeds use %ETHTOOL_SLINKSETTINGS to change link
++ * settings; do not use %ETHTOOL_SSET if %ETHTOOL_GLINKSETTINGS
++ * succeeded: stick to %ETHTOOL_GLINKSETTINGS/%SLINKSETTINGS in
++ * that case. Conversely, if %ETHTOOL_GLINKSETTINGS fails, use
++ * %ETHTOOL_GSET to query and %ETHTOOL_SSET to change link
++ * settings; do not use %ETHTOOL_SLINKSETTINGS if
++ * %ETHTOOL_GLINKSETTINGS failed: stick to
++ * %ETHTOOL_GSET/%ETHTOOL_SSET in that case.
++ *
++ * @cmd: Command number = %ETHTOOL_GLINKSETTINGS or %ETHTOOL_SLINKSETTINGS
++ * @speed: Link speed (Mbps)
++ * @duplex: Duplex mode; one of %DUPLEX_*
++ * @port: Physical connector type; one of %PORT_*
++ * @phy_address: MDIO address of PHY (transceiver); 0 or 255 if not
++ * applicable. For clause 45 PHYs this is the PRTAD.
++ * @autoneg: Enable/disable autonegotiation and auto-detection;
++ * either %AUTONEG_DISABLE or %AUTONEG_ENABLE
++ * @mdio_support: Bitmask of %ETH_MDIO_SUPPORTS_* flags for the MDIO
++ * protocols supported by the interface; 0 if unknown.
++ * Read-only.
++ * @eth_tp_mdix: Ethernet twisted-pair MDI(-X) status; one of
++ * %ETH_TP_MDI_*. If the status is unknown or not applicable, the
++ * value will be %ETH_TP_MDI_INVALID. Read-only.
++ * @eth_tp_mdix_ctrl: Ethernet twisted pair MDI(-X) control; one of
++ * %ETH_TP_MDI_*. If MDI(-X) control is not implemented, reads
++ * yield %ETH_TP_MDI_INVALID and writes may be ignored or rejected.
++ * When written successfully, the link should be renegotiated if
++ * necessary.
++ * @link_mode_masks_nwords: Number of 32-bit words for each of the
++ * supported, advertising, lp_advertising link mode bitmaps. For
++ * %ETHTOOL_GLINKSETTINGS: on entry, number of words passed by user
++ * (>= 0); on return, if handshake in progress, negative if
++ * request size unsupported by kernel: absolute value indicates
++ * kernel expected size and all the other fields but cmd
++ * are 0; otherwise (handshake completed), strictly positive
++ * to indicate size used by kernel and cmd field stays
++ * %ETHTOOL_GLINKSETTINGS, all other fields populated by driver. For
++ * %ETHTOOL_SLINKSETTINGS: must be valid on entry, ie. a positive
++ * value returned previously by %ETHTOOL_GLINKSETTINGS, otherwise
++ * refused. For drivers: ignore this field (use kernel's
++ * __ETHTOOL_LINK_MODE_MASK_NBITS instead), any change to it will
++ * be overwritten by kernel.
++ * @supported: Bitmap with each bit meaning given by
++ * %ethtool_link_mode_bit_indices for the link modes, physical
++ * connectors and other link features for which the interface
++ * supports autonegotiation or auto-detection. Read-only.
++ * @advertising: Bitmap with each bit meaning given by
++ * %ethtool_link_mode_bit_indices for the link modes, physical
++ * connectors and other link features that are advertised through
++ * autonegotiation or enabled for auto-detection.
++ * @lp_advertising: Bitmap with each bit meaning given by
++ * %ethtool_link_mode_bit_indices for the link modes, and other
++ * link features that the link partner advertised through
++ * autonegotiation; 0 if unknown or not applicable. Read-only.
++ * @transceiver: Used to distinguish different possible PHY types,
++ * reported consistently by PHYLIB. Read-only.
++ *
++ * If autonegotiation is disabled, the speed and @duplex represent the
++ * fixed link mode and are writable if the driver supports multiple
++ * link modes. If it is enabled then they are read-only; if the link
++ * is up they represent the negotiated link mode; if the link is down,
++ * the speed is 0, %SPEED_UNKNOWN or the highest enabled speed and
++ * @duplex is %DUPLEX_UNKNOWN or the best enabled duplex mode.
++ *
++ * Some hardware interfaces may have multiple PHYs and/or physical
++ * connectors fitted or do not allow the driver to detect which are
++ * fitted. For these interfaces @port and/or @phy_address may be
++ * writable, possibly dependent on @autoneg being %AUTONEG_DISABLE.
++ * Otherwise, attempts to write different values may be ignored or
++ * rejected.
++ *
++ * Deprecated %ethtool_cmd fields transceiver, maxtxpkt and maxrxpkt
++ * are not available in %ethtool_link_settings. These fields will be
++ * always set to zero in %ETHTOOL_GSET reply and %ETHTOOL_SSET will
++ * fail if any of them is set to non-zero value.
++ *
++ * Users should assume that all fields not marked read-only are
++ * writable and subject to validation by the driver. They should use
++ * %ETHTOOL_GLINKSETTINGS to get the current values before making specific
++ * changes and then applying them with %ETHTOOL_SLINKSETTINGS.
++ *
++ * Drivers that implement %get_link_ksettings and/or
++ * %set_link_ksettings should ignore the @cmd
++ * and @link_mode_masks_nwords fields (any change to them overwritten
++ * by kernel), and rely only on kernel's internal
++ * %__ETHTOOL_LINK_MODE_MASK_NBITS and
++ * %ethtool_link_mode_mask_t. Drivers that implement
++ * %set_link_ksettings() should validate all fields other than @cmd
++ * and @link_mode_masks_nwords that are not described as read-only or
++ * deprecated, and must ignore all fields described as read-only.

+- *
+- * Documentation
+- * =============
+- *
+- * The below enums and macros are for interfacing with WireGuard, using generic
+- * netlink, with family WG_GENL_NAME and version WG_GENL_VERSION. It defines two
+- * methods: get and set. Note that while they share many common attributes, these
+- * two functions actually accept a slightly different set of inputs and outputs.
+- *
+- * WG_CMD_GET_DEVICE
+- * -----------------
+- *
+- * May only be called via NLM_F_REQUEST | NLM_F_DUMP. The command should contain
+- * one but not both of:
+- *
+- * WGDEVICE_A_IFINDEX: NLA_U32
+- * WGDEVICE_A_IFNAME: NLA_NUL_STRING, maxlen IFNAMESIZ - 1
+- *
+- * The kernel will then return several messages (NLM_F_MULTI) containing the following
+- * tree of nested items:
+- *
+- * WGDEVICE_A_IFINDEX: NLA_U32
+- * WGDEVICE_A_IFNAME: NLA_NUL_STRING, maxlen IFNAMESIZ - 1
+- * WGDEVICE_A_PRIVATE_KEY: len WG_KEY_LEN
+- * WGDEVICE_A_PUBLIC_KEY: len WG_KEY_LEN
+- * WGDEVICE_A_LISTEN_PORT: NLA_U16
+- * WGDEVICE_A_FWMARK: NLA_U32
+- * WGDEVICE_A_PEERS: NLA_NESTED
+- * 0: NLA_NESTED
+- * WGPEER_A_PUBLIC_KEY: len WG_KEY_LEN
+- * WGPEER_A_PRESHARED_KEY: len WG_KEY_LEN
+- * WGPEER_A_ENDPOINT: struct sockaddr_in or struct sockaddr_in6
+- * WGPEER_A_PERSISTENT_KEEPALIVE_INTERVAL: NLA_U16
+- * WGPEER_A_LAST_HANDSHAKE_TIME: struct timespec
+- * WGPEER_A_RX_BYTES: NLA_U64
+- * WGPEER_A_TX_BYTES: NLA_U64
+- * WGPEER_A_ALLOWEDIPS: NLA_NESTED
+- * 0: NLA_NESTED
+- * WGALLOWEDIP_A_FAMILY: NLA_U16
+- * WGALLOWEDIP_A_IPADDR: struct in_addr or struct in6_addr
+- * WGALLOWEDIP_A_CIDR_MASK: NLA_U8
+- * 1: NLA_NESTED
+- * ...
+- * 2: NLA_NESTED
+- * ...
+- * ...
+- * 1: NLA_NESTED
+- * ...
+- * ...
+- *
+- * It is possible that all of the allowed IPs of a single peer will not
+- * fit within a single netlink message. In that case, the same peer will
+- * be written in the following message, except it will only contain
+- * WGPEER_A_PUBLIC_KEY and WGPEER_A_ALLOWEDIPS. This may occur several
+- * times in a row for the same peer. It is then up to the receiver to
+- * coalesce adjacent peers. Likewise, it is possible that all peers will
+- * not fit within a single message. So, subsequent peers will be sent
+- * in following messages, except those will only contain WGDEVICE_A_IFNAME
+- * and WGDEVICE_A_PEERS. It is then up to the receiver to coalesce these
+- * messages to form the complete list of peers.
+- *
+- * Since this is an NLA_F_DUMP command, the final message will always be
+- * NLMSG_DONE, even if an error occurs. However, this NLMSG_DONE message
+- * contains an integer error code. It is either zero or a negative error
+- * code corresponding to the errno.
+- *
+- * WG_CMD_SET_DEVICE
+- * -----------------
+- *
+- * May only be called via NLM_F_REQUEST. The command should contain the following
+- * tree of nested items, containing one but not both of WGDEVICE_A_IFINDEX
+- * and WGDEVICE_A_IFNAME:
+- *
+- * WGDEVICE_A_IFINDEX: NLA_U32
+- * WGDEVICE_A_IFNAME: NLA_NUL_STRING, maxlen IFNAMESIZ - 1
+- * WGDEVICE_A_FLAGS: NLA_U32, 0 or WGDEVICE_F_REPLACE_PEERS if all current
+- * peers should be removed prior to adding the list below.
+- * WGDEVICE_A_PRIVATE_KEY: len WG_KEY_LEN, all zeros to remove
+- * WGDEVICE_A_LISTEN_PORT: NLA_U16, 0 to choose randomly
+- * WGDEVICE_A_FWMARK: NLA_U32, 0 to disable
+- * WGDEVICE_A_PEERS: NLA_NESTED
+- * 0: NLA_NESTED
+- * WGPEER_A_PUBLIC_KEY: len WG_KEY_LEN
+- * WGPEER_A_FLAGS: NLA_U32, 0 and/or WGPEER_F_REMOVE_ME if the specified peer
+- * should be removed rather than added/updated and/or
+- * WGPEER_F_REPLACE_ALLOWEDIPS if all current allowed IPs of
+- * this peer should be removed prior to adding the list below.
+- * WGPEER_A_PRESHARED_KEY: len WG_KEY_LEN, all zeros to remove
+- * WGPEER_A_ENDPOINT: struct sockaddr_in or struct sockaddr_in6
+- * WGPEER_A_PERSISTENT_KEEPALIVE_INTERVAL: NLA_U16, 0 to disable
+- * WGPEER_A_ALLOWEDIPS: NLA_NESTED
+- * 0: NLA_NESTED
+- * WGALLOWEDIP_A_FAMILY: NLA_U16
+- * WGALLOWEDIP_A_IPADDR: struct in_addr or struct in6_addr
+- * WGALLOWEDIP_A_CIDR_MASK: NLA_U8
+- * 1: NLA_NESTED
+- * ...
+- * 2: NLA_NESTED
+- * ...
+- * ...
+- * 1: NLA_NESTED
+- * ...
+- * ...
+- *
+- * It is possible that the amount of configuration data exceeds that of
+- * the maximum message length accepted by the kernel. In that case,
+- * several messages should be sent one after another, with each
+- * successive one filling in information not contained in the prior. Note
+- * that if WGDEVICE_F_REPLACE_PEERS is specified in the first message, it
+- * probably should not be specified in fragments that come after, so that
+- * the list of peers is only cleared the first time but appened after.
+- * Likewise for peers, if WGPEER_F_REPLACE_ALLOWEDIPS is specified in the
+- * first message of a peer, it likely should not be specified in subsequent
+- * fragments.
+- *
+- * If an error occurs, NLMSG_ERROR will reply containing an errno.

-Subject: [PATCH] Allocate temporary strings to hold dbus paths on the heap
-
-Paths are limited to BUS_PATH_SIZE_MAX but the maximum size is anyway too big
-to be allocated on the stack, so let's switch to the heap where there is a
-clear way to understand if the allocation fails.

+Subject: [PATCH] linux: also import linux/in.h and in6.h from kernel-5.0
+
+Now linux/in.h has better conflict detection with glibc's
+netinet/in.h. So, let's import the headers.
+
+Note that our code already have many workarounds for the conflict,
+but in this commit does not drop them. Let's do that in the later
+commits if this really helps.

-Subject: [PATCH] meson: drop misplaced -Wl,--undefined argument
-
-Ld's man page says the following:
-
- -u symbol
- --undefined=symbol
-
- Force symbol to be entered in the output file as an undefined symbol. Doing
- this may, for example, trigger linking of additional modules from standard
- libraries. -u may be repeated with different option arguments to enter
- additional undefined symbols. This option is equivalent to the "EXTERN"
- linker script command.
-
- If this option is being used to force additional modules to be pulled into
- the link, and if it is an error for the symbol to remain undefined, then the
- option --require-defined should be used instead.
-
-This would imply that it always requires an argument, which this does not
-pass. Thus it will grab the next argument on the command line as its
-argument. Before it took one of the many -lrt args (presumably) and now it
-grabs something other random linker argument and things break.
-
-[zj: this line was added in the first version of the meson configuration back
-in 5c23128daba7236a6080383b2a5649033cfef85c. AFAICT, this was a mistake. No
-such flag appeared in Makefile.am at the time.]

+Subject: [PATCH] linux: also import l2tp.h from kernel-5.0
+
+The L2TP_ATTR_UDP_ZERO_CSUM6_{TX,RX} attributes are introduced by
+6b649feafe10b293f4bd5a74aca95faf625ae525, which is included in
+kernel-3.16. To support older kernel, let's import the header.
+
+Fixes #12300.

Removed patches that have been committed upstream. Backport patches required to build systemd on older kernels. Added symlinks required to enable some services. After extensive discussion with upstream it does not seem there is any acceptable option to have symlink installation handled on their side. The recommended solution from upstream is to have systemctl handle service installation, however this has a number of downsides such as requiring us to build a host-systemd just to install a few symlinks. Since we already customize service installation it is simpler for us to create the symlinks ourselves, this will also simplify service customization on our side as we will not need to disable any systemd default services in cases where we need to make customizations. In addition using systemctl would introduce a minimum host headers dependency in which we don't have the infrastructure to handle properly. The downside to this approach is that we need to track service creation changes from upstream ourselves, however this is relatively straightforward and since upstream service file locations are relatively stable regressions should be limited. This will mostly be a concern in regards to adding support for new systemd features.
