====================
pull-request: bpf 2021-06-23

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 9f2470fbc4 ("skmsg: Improve udp_bpf_recvmsg() accuracy") from bpf
with c49661aa6f ("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.
