prctl: cfi: change the branch landing pad prctl()s to be more descriptive

2026-04-05T00:40:58+00:00

Per Linus' comments requesting the replacement of "INDIR_BR_LP" in the
indirect branch tracking prctl()s with something more readable, and
suggesting the use of the speculation control prctl()s as an exemplar,
reimplement the prctl()s and related constants that control per-task
forward-edge control flow integrity.

This primarily involves two changes.  First, the prctls are
restructured to resemble the style of the speculative execution
workaround control prctls PR_{GET,SET}_SPECULATION_CTRL, to make them
easier to extend in the future.  Second, the "indir_br_lp" abbrevation
is expanded to "branch_landing_pads" to be less telegraphic.  The
kselftest and documentation is adjusted accordingly.

perf beauty: Sync UAPI linux/fs.h with kernel sources

2026-03-04T14:46:01+00:00

To pick up changes from:

  0e6b7eae1fded85f ("fs: add FS_XFLAG_VERITY for fs-verity files")

These are used to beautify fs syscall arguments, albeit the changes in
this update are not affecting those beautifiers.

This addresses these tools/perf build warnings:

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

Please see tools/include/uapi/README.

perf beauty: Sync linux/mount.h copy with the kernel sources

2026-03-04T14:41:12+00:00

To pick the changes from:

  9b8a0ba68246a61d ("mount: add OPEN_TREE_NAMESPACE")
  0e5032237ee55301 ("statmount: accept fd as a parameter")

That doesn't change anything in tools this time as nothing that is
harvested by the beauty scripts got changed:

  $ ls -1 tools/perf/trace/beauty/*mount*sh
  tools/perf/trace/beauty/fsmount.sh
  tools/perf/trace/beauty/mount_flags.sh
  tools/perf/trace/beauty/move_mount_flags.sh
  $

This addresses this perf build warning.

  Warning: Kernel ABI header differences:

That don't introduced these new prctls:
