When booting a Linux kernel via network, it's sometimes more convenient to load the kernel and initrd separately instead of having to create a joint kernel + initrd file. The most common "standard" for doing such network boots are the so-called pxelinux.cfg config files, initially introduced by the PXELINUX bootloader on x86, but nowadays also used on ppc64 by petitboot for example. So let's support booting via these config files in SLOF, too! v3: - Addressed Alexey's review feedback from v2 v2: - Added support for UUID-based file names (last two patches) - Addressed Greg's feedback from v1 Thomas Huth (8): libnet: Pass ip_version via struct filename_ip libc: Add the snprintf() function libnet: Put code for determing TFTP error strings into a separate function libnet: Add functions for downloading and parsing pxelinux.cfg files libnet: Wire up pxelinux.cfg network booting libnet: Add support for DHCPv4 options 209 and 210 slof: Add a helper function to get the contents of a property in C code libnet: Support UUID-based pxelinux.cfg file names include/helpers.h | 4 + lib/libc/include/stdio.h | 1 + lib/libc/stdio/Makefile.inc | 2 +- lib/libc/stdio/snprintf.c | 28 +++++ lib/libnet/Makefile | 2 +- lib/libnet/dhcp.c | 33 ++++++ lib/libnet/netload.c | 189 +++++++++++++++++++-------------- lib/libnet/ping.c | 14 ++- lib/libnet/pxelinux.c | 248 ++++++++++++++++++++++++++++++++++++++++++++ lib/libnet/pxelinux.h | 33 ++++++ lib/libnet/tftp.c | 105 ++++++++++++++++++- lib/libnet/tftp.h | 14 ++- slof/helpers.c | 30 +++++- 13 files changed, 608 insertions(+), 95 deletions(-) create mode 100644 lib/libc/stdio/snprintf.c create mode 100644 lib/libnet/pxelinux.c create mode 100644 lib/libnet/pxelinux.h
