      perf lock contention: Factor out lock_type_table · 59119c09
      Namhyung Kim authored
      Move it out of get_type_str() so that we can reuse the table for others
      later.

      perf probe: Check -v and -q options in the right place · 8b269b75
      Yang Jihong authored
      Check the -q and -v options first to return earlier on error.
      
      Before:
      
        # perf probe -q -v test
        probe-definition(0): test

          Error: -v and -q are exclusive.
      
      After:
      
        # perf probe -q -v test
          Error: -v and -q are exclusive.

      perf debug: Set debug_peo_args and redirect_to_stderr variable to correct... · 188ac720
      Yang Jihong authored
      perf debug: Set debug_peo_args and redirect_to_stderr variable to correct values in perf_quiet_option()
      
      When perf uses quiet mode, perf_quiet_option() sets the 'debug_peo_args'
      variable to -1, and display_attr() incorrectly determines the value of
      'debug_peo_args'.  As a result, unexpected information is displayed.
      
      Before:

      tools headers UAPI: Sync linux/kvm.h with the kernel sources · b235e5b5
      Arnaldo Carvalho de Melo authored
      To pick the changes in:
      
        86bdf3eb ("KVM: Support dirty ring in conjunction with bitmap")
      
      That just rebuilds perf, as these patches don't add any new KVM ioctl to
      be harvested for the the 'perf trace' ioctl syscall argument
      beautifiers.
      
      This is also by now used by tools/testing/selftests/kvm/, a simple test
      build didn't succeed, but for another reason:
      
        lib/kvm_util.c: In function ‘vm_enable_dirty_ring’:
        lib/kvm_util.c:125:30: error: ‘KVM_CAP_DIRTY_LOG_RING_ACQ_REL’ undeclared (first use in this function); did you mean ‘KVM_CAP_DIRTY_LOG_RING’?
          125 |         if (vm_check_cap(vm, KVM_CAP_DIRTY_LOG_RING_ACQ_REL))
              |                              ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
              |                              KVM_CAP_DIRTY_LOG_RING
      
      I'll send a separate patch for that.
      
      This silences this perf build warning:

      Now one can trace systemwide asking to see backtraces to where that MSR
      is being read/written, see this example with a previous update:

        ^C#
      
      If we use -v (verbose mode) we can see what it does behind the scenes:
      
        # perf trace -v -e msr:*_msr/max-stack=32/ --filter="msr>=IA32_U_CET && msr<=IA32_INT_SSP_TAB"

      perf python: Don't stop building if python setuptools isn't installed · 66dfc517
      Arnaldo Carvalho de Melo authored
      The python3-setuptools package is needed to build the python binding, so
      that one can use things like:
      
        # ~acme/git/perf/tools/perf/python/twatch.py
        cpu: 6, pid: 4573, tid: 2184618 { type: exit, pid: 4573, ppid: 4172, tid: 2184618, ptid: 4172, time: 12563190090107}
        cpu: 24, pid: 4573, tid: 4573 { type: fork, pid: 4573, ppid: 4573, tid: 2190991e, ptid: 4573, time: 12563415289331}
        cpu: 29, pid: 4573, tid: 2190991e { type: comm, pid: 4573, tid: 2190991e, comm: StreamT~ns #401 }
        cpu: 29, pid: 4573, tid: 2190991e { type: comm, pid: 4573, tid: 2190991e, comm: StreamT~ns #401 }
        ^CTraceback (most recent call last):
          File "/var/home/acme/git/perf/tools/perf/python/twatch.py", line 61, in <module>
            main()
          File "/var/home/acme/git/perf/tools/perf/python/twatch.py", line 33, in main
            evlist.poll(timeout = -1)
        KeyboardInterrupt
      
        #
      
      That have 'import perf;'.
      
      But distros don't always have that python3-setuptools (or equivalent)
      installed, which was breaking the build. Just check if it is installed
      and emit a warning that such binding isn't being built and continue the
      build without it:
      
      With it:
      
        $ rpm -q python3-setuptools
        python3-setuptools-59.6.0-3.fc36.noarch
        $ rm -rf /tmp/build/perf; mkdir -p /tmp/build/perf
        $ make O=/tmp/build/perf -C tools/perf install-bin
        make: Entering directory '/var/home/acme/git/perf/tools/perf'

        <SNIP>
          GEN     /tmp/build/perf/python/perf.cpython-310-x86_64-linux-gnu.so

        $
      
      Without it:
      
        $ sudo rpm -e python3-setuptools
        $ rm -rf /tmp/build/perf ; mkdir -p /tmp/build/perf
        $ make O=/tmp/build/perf -C tools/perf install-bin

       "This contains a number of crasher fixes that were not ready for the
        initial pull request last week.
      
        In particular, Jeff's patch attempts to address reference count
        underflows in NFSD's filecache, which have been very difficult to
        track down because there is no reliable reproducer.
      
        Common failure modes:

            https://bugzilla.redhat.com/show_bug.cgi?id=2138605
      
        The race windows were found by inspection and the clean-ups appear
        sensible and pass regression testing, so we include them here in the
        hope that they address the problem. However we remain vigilant because
        we don't have 100% certainty yet that the problem is fully addressed.
      
        Summary:
      
         - Address numerous reports of refcount underflows in NFSD's filecache
      
         - Address a UAF in callback setup error handling
