perf beauty: Add socket level scnprintf that handles ARCH specific SOL_SOCKET

2021-11-12T13:40:34+00:00

SOL_SOCKET has a different value according to the architecture, some
have it as 0xffff while all the others have it as 1, so a simple string
array isn't usable, add a scnprintf routine that treats it as a special
case, using the array for other values.

perf beauty socket: Sort the ipproto array entries

perf beauty socket: Rename 'regex' to 'ipproto_regex'

Paving the way for more regexps to be used here.

perf beauty socket: Prep to receive more input header files

2021-11-12T13:40:34+00:00

Move from ternary like expression to an if block, this way we'll
have just the extra lines for new files in the following patches.

perf beauty socket: Rename header_dir to uapi_header_dir

2021-11-12T13:40:34+00:00

Paving the way to pass more headers to be consumed, like
tools/perf/trace/beauty/include/linux/socket.h in addition to the
current tools/include/uapi/linux/in.h, to get the SOL_* defines.

perf beauty: Rename socket_ipproto.sh to socket.sh to hold more socket table generators

2021-11-12T13:40:34+00:00

To avoid having to add new entries to tools/perf/Makefile.perf prep
socket.sh so that it can generate other socket table generators, such as
the upcoming SOL_ socket level one.

perf beauty: Make all sockaddr files use a common naming scheme

2021-11-12T13:40:34+00:00

The script that generates the tables was named 'socket.sh', which is
confusing, rename it to sockaddr.sh and make sure the related
Makefile.perf targets also use the 'sockaddr' namespace.

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

2021-11-06T20:54:42+00:00

To pick the changes in:

  99ce45d5e7dbde39 ("mctp: Implement extended addressing")
  55c42fa7fa331f98 ("mptcp: add MPTCP_INFO getsockopt")

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

A table generator for setsockopt is needed, probably will be done in the
5.16 cycle.

This silences this perf build warning:

  Warning: Kernel ABI header at 'tools/perf/trace/beauty/include/linux/socket.h' differs from latest version at 'include/linux/socket.h'
  diff -u tools/perf/trace/beauty/include/linux/socket.h include/linux/socket.h

perf beauty: Cover more flags in the move_mount syscall argument beautifier

2021-09-10T21:15:22+00:00

Previously the regext expected MOVE_MOUNT_[FT]_*, but in the next patch
a flag that doesn't match that expression will be added, MOVE_MOUNT_SET_GROUP

To make this more future proof, take advantage of the fact that the only
one we don't need to cover is MOVE_MOUNT__MASK and use MOVE_MOUNT_[^_]+_*_.
