A more complex rule\ncan be added by user to specify that for a specific interface, a packet\nshould be look up at either an arbitrary table or according to the l3mdev\nof the interface.\n\nFor drivers willing to offload the ipmr logic into a hardware but don't\nwant to offload all the FIB rules functionality, provide a function that\ncan indicate whether the FIB rule is the default multicast rule, thus only\none routing table is needed.\n\nThis way, a driver can register to the FIB notification chain, get\nnotifications about FIB rules added and trigger some kind of an internal\nabort mechanism when a non default rule is added by the user.\n\nSigned-off-by: Yotam Gigi <yotamg@mellanox.com>\nReviewed-by: Ido Schimmel <idosch@mellanox.com>\nSigned-off-by: Jiri Pirko <jiri@mellanox.com>\n---\n include/linux/mroute.h | 7 +++++++\n net/ipv4/ipmr.c | 10 ++++++++++\n 2 files changed, 17 insertions(+)", "diff": "diff --git a/include/linux/mroute.h b/include/linux/mroute.h\nindex 5566580..b072a84 100644\n--- a/include/linux/mroute.h\n+++ b/include/linux/mroute.h\n@@ -5,6 +5,7 @@\n #include <linux/pim.h>\n #include <linux/rhashtable.h>\n #include <net/sock.h>\n+#include <net/fib_rules.h>\n #include <net/fib_notifier.h>\n #include <uapi/linux/mroute.h>\n \n@@ -19,6 +20,7 @@ int ip_mroute_getsockopt(struct sock *, int, char __user *, int __user *);\n int ipmr_ioctl(struct sock *sk, int cmd, void __user *arg);\n int ipmr_compat_ioctl(struct sock *sk, unsigned int cmd, void __user *arg);\n int ip_mr_init(void);\n+bool ipmr_rule_default(const struct fib_rule *rule);\n #else\n static inline int ip_mroute_setsockopt(struct sock *sock, int optname,\n \t\t\t\t char __user *optval, unsigned int optlen)\n@@ -46,6 +48,11 @@ static inline int ip_mroute_opt(int opt)\n {\n \treturn 0;\n }\n+\n+static inline bool ipmr_rule_default(const struct fib_rule *rule)\n+{\n+\treturn true;\n+}\n #endif\n \n struct vif_device {\ndiff --git a/net/ipv4/ipmr.c b/net/ipv4/ipmr.c\nindex 2a795d2..a714f55 100644\n--- a/net/ipv4/ipmr.c\n+++ b/net/ipv4/ipmr.c\n@@ -320,6 +320,16 @@ static unsigned int ipmr_rules_seq_read(struct net *net)\n }\n #endif\n \n+bool ipmr_rule_default(const struct fib_rule *rule)\n+{\n+#if IS_ENABLED(CONFIG_FIB_RULES)\n+\treturn fib_rule_matchall(rule) && rule->table == RT_TABLE_DEFAULT;\n+#else\n+\treturn true;\n+#endif\n+}\n+EXPORT_SYMBOL(ipmr_rule_default);\n+\n static inline int ipmr_hash_cmp(struct rhashtable_compare_arg *arg,\n \t\t\t\tconst void *ptr)\n {\n", "prefixes": [ "net-next", "v2", "06/12" ] }
