Hi David, hi Jakub, The following pull-request contains BPF updates for your *net* tree. We've added 14 non-merge commits during the last 6 day(s) which contain a total of 13 files changed, 137 insertions(+), 64 deletions(-). Note that when you merge net into net-next, there is a small merge conflict between 9f2470fbc4cb ("skmsg: Improve udp_bpf_recvmsg() accuracy") from bpf with c49661aa6f70 ("skmsg: Remove unused parameters of sk_msg_wait_data()") from net-next. Resolution is to: i) net/ipv4/udp_bpf.c: take udp_msg_wait_data() and remove err parameter from the function, ii) net/ipv4/tcp_bpf.c: take tcp_msg_wait_data() and remove err parameter from the function, iii) for net/core/skmsg.c and include/linux/skmsg.h: remove the sk_msg_wait_data() implementation and its prototype in header. The main changes are: 1) Fix BPF poke descriptor adjustments after insn rewrite, from John Fastabend. 2) Fix regression when using BPF_OBJ_GET with non-O_RDWR flags, from Maciej Żenczykowski. 3) Various bug and error handling fixes for UDP-related sock_map, from Cong Wang. 4) Fix patching of vmlinux BTF IDs with correct endianness, from Tony Ambardar. 5) Two fixes for TX descriptor validation in AF_XDP, from Magnus Karlsson. 6) Fix overflow in size calculation for bpf_map_area_alloc(), from Bui Quang Minh.
