Hello: This series was applied to bpf/bpf.git (master) by Daniel Borkmann [off-list ref]: On Mon, 25 Sep 2023 20:52:57 -0700 you wrote:
With e5c6de5fa0258 ("bpf, sockmap: Incorrectly handling copied_seq") we
started fixing the available bytes accounting by moving copied_seq to
where the user actually reads the bytes.
However we missed handling MSG_PEEK correctly and we need to ensure
that we don't kfree_skb() a skb off the receive_queue when the
copied_seq number is not incremented by user reads for some time.
[...]
Here is the summary with links:
- [bpf,v3,1/3] bpf: tcp_read_skb needs to pop skb regardless of seq
https://git.kernel.org/bpf/bpf/c/9b7177b1df64
- [bpf,v3,2/3] bpf: sockmap, do not inc copied_seq when PEEK flag set
https://git.kernel.org/bpf/bpf/c/da9e915eaf5d
- [bpf,v3,3/3] bpf: sockmap, add tests for MSG_F_PEEK

You are awesome, thank you!
