Subject: [PATCH v5 bpf-next 0/4] BPF iterator for UNIX domain socket.
Date: Fri, 13 Aug 2021 01:45:53 +0900 [thread overview]
Message-ID: <20210812164557.79046-1-kuniyu@amazon.co.jp> (raw)
This patch set adds BPF iterator support for UNIX domain socket. The first
patch implements it, and the second adds "%c" support for BPF_SEQ_PRINTF().
Changelog:
v5:
- Align header line of bpf_iter_unix.c
- Add test for "%c"
v4:
https://lore.kernel.org/netdev/20210810092807.13190-1-kuniyu@amazon.co.jp/
- Check IS_BUILTIN(CONFIG_UNIX)
- Support "%c" in BPF_SEQ_PRINTF()
- Uncomment the code to print the name of the abstract socket
- Mention the LLVM fix in README.rst
- Remove the 'aligned' attribute in bpf_iter.h
- Keep the format string on a single line
v3:
https://lore.kernel.org/netdev/20210804070851.97834-1-kuniyu@amazon.co.jp/
- Export some functions for CONFIG_UNIX=m
v2:
https://lore.kernel.org/netdev/20210803011110.21205-1-kuniyu@amazon.co.jp/
- Implement bpf_iter specific seq_ops->stop()
- Add bpf_iter__unix in bpf_iter.h
- Move common definitions in selftest to bpf_tracing_net.h
- Include the code for abstract UNIX domain socket as comment in selftest
- Use ASSERT_OK_PTR() instead of CHECK()
- Make ternary operators on single line
v1:
https://lore.kernel.org/netdev/20210729233645.4869-1-kuniyu@amazon.co.jp/
Kuniyuki Iwashima (4):
bpf: af_unix: Implement BPF iterator for UNIX domain socket.
bpf: Support "%c" in bpf_bprintf_prepare().
selftest/bpf: Implement sample UNIX domain socket iterator program.
selftest/bpf: Extend the bpf_snprintf() test for "%c".
