Hello, This series contains patches that come from the SUSE package that adds a net_bootp6 command to auto configure the network interfaces by using the DHCPv6 protocol. They also add support to do the auto configuration when GRUB is booted from UEFI IPv6 PXE.
We have been carrying these for a long time in our grub2 package and is also used by other distros such as Debian and Ubuntu. Michael Chang posted them in 2016 but were never merged: https://lists.gnu.org/archive/html/grub-devel/2016-08/msg00000.html Without these patches, booting GRUB from a UEFI PXEv6 boot entry leads to a wrong network configuration and GRUB not being able to fetch its config file over TFTP. For example, the following variables are incorrectly set: cmdpath=(tftp,0.5.0.24)d:beef:a::1]/netboot net_default_ip=0.0.0.0 net_default_mac=be:ef:00:0a:00:00 net_default_server=0.5.0.24 net_efinet0_boot_file=d:beef:a::1]/netboot/grubx64.efi net_efinet0_ip=0.0.0.0 net_efinet0_mac=be:ef:00:0a:00:00 net_efinet0_next_server=0.5.0.24 prefix=(tftp,0.5.0.24)/netboot pxe_default_server=0.5.0.24 root=tftp,0.5.0.24 With these changes, the network interface is correctly configured and GRUB is able to fetch its config file. The network variables are correctly set: cmdpath=(tftp,2000:dead:beef:a::1)/netboot net_default_ip=2000:dead:beef:a:0:0:0:2000 net_default_mac=52:54:00:2c:dc:9e net_default_server=2000:dead:beef:a::1 net_efinet0_boot_file=/netboot/grubx64.efi net_efinet0_ip=2000:dead:beef:a:0:0:0:2000 net_efinet0_mac=52:54:00:2c:dc:9e prefix=(tftp,2000:dead:beef:a::1)/netboot pxe_default_server=2000:dead:beef:a::1 root=tftp,2000:dead:beef:a::1 Aaron Miller (1): net: read bracketed ipv6 addrs and port numbers Michael Chang (3): bootp: New net_bootp6 command efinet: UEFI IPv6 PXE support grub.texi: Add net_bootp6 document docs/grub.texi | 19 + grub-core/net/bootp.c | 914 ++++++++++++++++++++++++++++- grub-core/net/drivers/efi/efinet.c | 45 +- grub-core/net/http.c | 25 +- grub-core/net/ip.c | 39 ++ grub-core/net/net.c | 159 ++++- grub-core/net/tftp.c | 10 +- include/grub/efi/api.h | 146 ++++- include/grub/net.h | 80 +++ 9 files changed, 1411 insertions(+), 26 deletions(-) -- 2.26.2 _______________________________________________ Grub-devel mailing list Grub-devel@gnu.org https://lists.gnu.org/mailman/listinfo/grub-devel
