      perf session: Return error code for perf_session__new() function on failure · 6ef81c55
      Mamatha Inamdar authored 
      

This patch is to return error code of perf_new_session function on
failure instead of NULL.

Test Results:

Before Fix:

  $ perf c2c report -input
  failed to open nput: No such file or directory

  $ echo $?
  0
  $

After Fix:

  $ perf c2c report -input
  failed to open nput: No such file or directory

  $ echo $?
  254
  $

Committer notes:

Fix 'perf tests topology' case, where we use that TEST_ASSERT_VAL(...,
session), i.e. we need to pass zero in case of failure, which was the
case before when NULL was returned by perf_session__new() for failure,
but now we need to negate the result of IS_ERR(session) to respect that
TEST_ASSERT_VAL) expectation of zero meaning failure.

      perf probe: Fix to clear tev->nargs in clear_probe_trace_event() · 9e6124d9
      Masami Hiramatsu authored 
      Since add_probe_trace_event() can reuse tf->tevs[i] after calling
clear_probe_trace_event(), this can make perf-probe crash if the 1st
attempt of probe event finding fails to find an event argument, and the
2nd attempt fails to find probe point.

E.g.
  $ perf probe -D "task_pid_nr tsk"
  Failed to find 'tsk' in this function.
  Failed to get entry address of warn_bad_vsyscall
  Segmentation fault (core dumped)

Committer testing:

After the patch:

  $ perf probe -D "task_pid_nr tsk"
  Failed to find 'tsk' in this function.
  Failed to get entry address of warn_bad_vsyscall
  Failed to get entry address of signal_fault
  Failed to get entry address of show_signal
  Failed to get entry address of umip_printk
  Failed to get entry address of __bad_area_nosemaphore

  Failed to get entry address of sock_set_timeout
  Failed to get entry address of tcp_recvmsg
  Probe point 'task_pid_nr' not found.

      perf probe: Skip same probe address for a given line · 1a375ae7
      Masami Hiramatsu authored 
      

Fix to skip making a same probe address on given line.

Since a DWARF line info contains several entries for one line with
different column, perf probe will make a different probe on same address
if user specifies a probe point by "function:line" or "file:line".

e.g.
 $ perf probe -D kernel_read:8
 p:probe/kernel_read_L8 kernel_read+39
 p:probe/kernel_read_L8_1 kernel_read+39

This skips such duplicated probe addresses.

Being able to pass something like:

  # perf record -e syscalls:sys_enter_prctl --filter="option=*TAGGED_ADDR*"

Should be easy enough, first using tracepoint filters, then via the
augmented_raw_syscalls.c BPF method.

 "Timers and timekeeping updates:

   - A large overhaul of the posix CPU timer code which is a preparation

     properly accounted on the task/process.

     An update to the bogus permission checks will come later during the
     merge window as feedback was not complete before heading of for
     travel.

   - Switch the timerqueue code to use cached rbtrees and get rid of the
     homebrewn caching of the leftmost node.

   - Consolidate hrtimer_init() + hrtimer_init_sleeper() calls into a
     single function

   - Implement the separation of hrtimers to be forced to expire in hard
     interrupt context even when PREEMPT_RT is enabled and mark the
     affected timers accordingly.

   - Implement a mechanism for hrtimers and the timer wheel to protect
     RT against priority inversion and live lock issues when a (hr)timer
     which should be canceled is currently executing the callback.
     Instead of infinitely spinning, the task which tries to cancel the
     timer blocks on a per cpu base expiry lock which is held and
     released by the (hr)timer expiry code.

   - Enable the Hyper-V TSC page based sched_clock for Hyper-V guests
     resulting in faster access to timekeeping functions.

   - Updates to various clocksource/clockevent drivers and their device
     tree bindings.

 - Cleanup the apic IPI implementation by removing duplicated code and
   consolidating the functions into the APIC core.

 - Implement a safe variant of the IPI broadcast mode. Contrary to
   earlier attempts this uses the core tracking of which CPUs have been
   brought online at least once so that a broadcast does not end up in
   some dead end in BIOS/SMM code when the CPU is still waiting for
   init. Once all CPUs have been brought up once, IPI broadcasting is
   enabled. Before that regular one by one IPIs are issued.

 - Drop the paravirt CR8 related functions as they have no user anymore

 - Initialize the APIC TPR to block interrupt 16-31 as they are reserved
   for CPU exceptions and should never be raised by any well behaving
   device.

 - Emit a warning when vector space exhaustion breaks the admin set
   affinity of an interrupt.

 - Make sure to use the NMI fallback when shutdown via reboot vector IPI
   fails. The original code had conditions which prevent the code path
   to be reached.

 - Annotate various APIC config variables as RO after init.

      Merge branch 'irq-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip · a572ba63
      Linus Torvalds authored 
      Pull core irq updates from Thomas Gleixner:
 "Updates from the irq departement:

   - Update the interrupt spreading code so it handles numa node with
     different CPU counts properly.

   - A large overhaul of the ARM GiCv3 driver to support new PPI and SPI
     ranges.

   - Conversion of all alloc_fwnode() users to use physical addresses
     instead of virtual addresses so the virtual addresses are not
     leaked. The physical address is sufficient to identify the
     associated interrupt chip.

   - Add support for Marvel MMP3, Amlogic Meson SM1 interrupt chips.

   - Enforce interrupt threading at compile time if RT is enabled.

   - Small updates and improvements all over the place"
