tools headers: Sync linux/socket.h with kernel sources

2025-12-24T19:43:29+00:00

To pick up changes from:

  d73c167708739137 ("socket: Split out a getsockname helper for io_uring")
  4677e78800bbde62 ("socket: Unify getsockname and getpeername implementation")
  bf33247a90d3e85d ("net: Add struct sockaddr_unsized for sockaddr of unknown length")

This should be used to beautify socket syscall arguments and it addresses
these tools/perf build warnings:

  Warning: Kernel ABI header differences:
    diff -u tools/perf/trace/beauty/include/linux/socket.h include/linux/socket.h

Please see tools/include/uapi/README.

net: Convert struct sockaddr to fixed-size "sa_data[14]"

2025-11-05T03:10:33+00:00

Revert struct sockaddr from flexible array to fixed 14-byte "sa_data",
to solve over 36,000 -Wflex-array-member-not-at-end warnings, since
struct sockaddr is embedded within many network structs.

With socket/proto sockaddr-based internal APIs switched to use struct
sockaddr_unsized, there should be no more uses of struct sockaddr that
depend on reading beyond the end of struct sockaddr::sa_data that might
trigger bounds checking.

Comparing an x86_64 "allyesconfig" vmlinux build before and after this
patch showed no new "ud1" instructions from CONFIG_UBSAN_BOUNDS nor any
new "field-spanning" memcpy CONFIG_FORTIFY_SOURCE instrumentations.

perf beauty: Update copy of linux/socket.h with the kernel sources

2025-06-16T17:05:11+00:00

To pick the changes in:

  b1e904999542ad67 ("net: pass const to msg_data_left()")

That don't result in any changes in the tables generated from that
header.

This silences this perf build warning:

  Warning: Kernel ABI header differences:

perf beauty: Update copy of linux/socket.h with the kernel sources

2024-09-30T20:23:38+00:00

To pick the changes in:

  8f0b3cc9a4c102c2 ("tcp: RX path for devmem TCP")

That don't result in any changes in the tables generated from that
header.

But while updating I noticed we need to support the new MSG_SOCK_DEVMEM
flag in the hard coded table for the msg flags table, add it.

perf beauty: Update copy of linux/socket.h with the kernel sources

2024-05-27T15:49:18+00:00

To pick up the fixes in:

  0645fbe760afcc53 ("net: have do_accept() take a struct proto_accept_arg argument")

That just changes a function prototype, not touching things used by the
perf scrape scripts such as:

  $ tools/perf/trace/beauty/sockaddr.sh | head -5
  static const char *socket_families[] = {
  	[0] = "UNSPEC",
  	[1] = "LOCAL",
  	[2] = "INET",
  	[3] = "AX25",
  $

net: remove {revc,send}msg_copy_msghdr() from exports

2024-03-14T23:48:53+00:00

The only user of these was io_uring, and it's not using them anymore.
Make them static and remove them from the socket header file.

tools headers: Update tools's copy of socket.h header

2023-11-22T18:57:47+00:00

tldr; Just FYI, I'm carrying this on the perf tools tree.

Full explanation:

There used to be no copies, with tools/ code using kernel headers
directly. From time to time tools/perf/ broke due to legitimate kernel
hacking. At some point Linus complained about such direct usage. Then we
adopted the current model.

The way these headers are used in perf are not restricted to just
including them to compile something.

There are sometimes used in scripts that convert defines into string
tables, etc, so some change may break one of these scripts, or new MSRs
may use some different #define pattern, etc.

E.g.:

  $ ls -1 tools/perf/trace/beauty/*.sh | head -5
  tools/perf/trace/beauty/arch_errno_names.sh
  tools/perf/trace/beauty/drm_ioctl.sh
  tools/perf/trace/beauty/fadvise.sh
  tools/perf/trace/beauty/fsconfig.sh
  tools/perf/trace/beauty/fsmount.sh
  $
  $ tools/perf/trace/beauty/fadvise.sh
  static const char *fadvise_advices[] = {
        [0] = "NORMAL",
        [1] = "RANDOM",
        [2] = "SEQUENTIAL",
        [3] = "WILLNEED",
        [4] = "DONTNEED",
        [5] = "NOREUSE",
  };
  $

The tools/perf/check-headers.sh script, part of the tools/ build
process, points out changes in the original files.

So its important not to touch the copies in tools/ when doing changes in
the original kernel headers, that will be done later, when
check-headers.sh inform about the change to the perf tools hackers.

perf beauty: Update copy of linux/socket.h with the kernel sources

2023-07-14T12:59:56+00:00

To pick the changes in:

  b848b26c6672c9b9 ("net: Kill MSG_SENDPAGE_NOTLAST")
  5e2ff6704a275be0 ("scm: add SO_PASSPIDFD and SCM_PIDFD")
  4fe38acdac8a71f7 ("net: Block MSG_SENDPAGE_* from being passed to sendmsg() by userspace")
  b841b901c452d926 ("net: Declare MSG_SPLICE_PAGES internal sendmsg() flag")

That don't result in any changes in the tables generated from that
header.

But while updating I noticed we were not handling MSG_BATCH and MSG_ZEROCOPY in the
hard coded table for the msg flags table, add them.

This silences this perf build warning:
