git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core
Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:
perf trace: (Arnaldo Carvalho de Melo)
- Do not require --no-syscalls to suppress strace like output, i.e.
# perf trace -e sched:*switch
will show just sched:sched_switch events, not strace-like formatted
syscall events, use --syscalls to get the previous behaviour.
If instead:
# perf trace
is used, i.e. no events specified, then --syscalls is implied and
system wide strace like formatting will be applied to all syscalls.
The behaviour when just a syscall subset is used with '-e' is unchanged:
# perf trace -e *sleep,sched:*switch
will work as before: just the 'nanosleep' syscall will be strace-like
formatted plus the sched:sched_switch tracepoint event, system wide.
- Allow string table generators to use a default header dir, allowing
use of them without parameters to see the table it generates on
stdout, e.g.:
$ tools/perf/trace/beauty/kvm_ioctl.sh
static const char *kvm_ioctl_cmds[] = {
[0x00] = "GET_API_VERSION",
[0x01] = "CREATE_VM",
[0x02] = "GET_MSR_INDEX_LIST",
[0x03] = "CHECK_EXTENSION",
<BIG SNIP>
[0xe0] = "CREATE_DEVICE",
[0xe1] = "SET_DEVICE_ATTR",
[0xe2] = "GET_DEVICE_ATTR",
[0xe3] = "HAS_DEVICE_ATTR",
};
$
See 'ls tools/perf/trace/beauty/*.sh' to see the available string
table generators.
- Add a generator for IPPROTO_ socket's protocol constants.
perf record: (Kan Liang)
- Fix error out while applying initial delay and using LBR, due to
the use of a PERF_TYPE_SOFTWARE/PERF_COUNT_SW_DUMMY event to track
PERF_RECORD_MMAP events while waiting for the initial delay. Such
events fail when configured asking PERF_SAMPLE_BRANCH_STACK in
perf_event_attr.sample_type.
perf c2c: (Jiri Olsa)
- Fix report crash for empty browser, when processing a perf.data file
without events of interest, either because not asked for in
'perf record' or because the workload didn't triggered such events.
perf list: (Michael Petlan)
- Align metric group description format with PMU event description.
perf tests: (Sandipan Das)
- Fix indexing when invoking subtests, which caused BPF tests to
get results for the next test in the list, with the last one
reporting a failure.
eBPF:
- Fix installation directory for header files included from eBPF proggies,
avoiding clashing with relative paths used to build other software projects
such as glibc. (Thomas Richter)
- Show better message when failing to load an object. (Arnaldo Carvalho de Melo)
General: (Christophe Leroy)
- Allow overriding MAX_NR_CPUS at compile time, to make the tooling
usable in systems with less memory, in time this has to be changed
to properly allocate based on _NPROCESSORS_ONLN.
Architecture specific:
- Update arm64's ThunderX2 implementation defined pmu core events (Ganapatrao Kulkarni)
- Fix complex event name parsing in 'perf test' for PowerPC, where the 'umask' event
modifier isn't present. (Sandipan Das)
CoreSight ARM hardware tracing: (Leo Yan)
- Fix start tracing packet handling.
- Support dummy address value for CS_ETM_TRACE_ON packet.
- Generate branch sample when receiving a CS_ETM_TRACE_ON packet.
- Generate branch sample for CS_ETM_TRACE_ON packet.

The periphery can't be accessed before we set the
INIT_DONE bit which initializes the device.
A previous patch added a reconfiguration of the MSI-X
tables upon resume, but at that point in the flow,
INIT_DONE wasn't set. Since the reconfiguration of the
MSI-X tables require periphery access, it failed.
The difference between WoWLAN and without WoWLAN is that
in WoWLAN, iwl_trans_pcie_d3_suspend clears the INIT_DONE
without clearing the STATUS_DEVICE_ENABLED bit in the
software status. Because of that, the resume code thinks
that the device is enabled, but the INIT_DONE bit has been
cleared.
To fix this, don't reconfigure the MSI-X tables in case
WoWLAN is enabled. It will be done in
iwl_trans_pcie_d3_resume anyway.

The rfh for 22560 devices has changed so it supports now
the same arch of using used and free lists, but different
structures to support the last.
Use the new structures, hw dependent, to manage the lists.
bd, the free list, uses the iwl_rx_transfer_desc,
in which the vid is stored in the structs' rbid
field, and the page address in the addr field.
used_bd, the used list, uses the iwl_rx_completion_desc
struct, in which the vid is stored in the structs' rbid
field.
rb_stts, the hw "write" pointer of rx is stored in a
__le16 array, in which each entry represents the write
pointer per queue.

'ac->ac_g_ex.fe_len' is a user-controlled value which is used in the
derivation of 'ac->ac_2order'. 'ac->ac_2order', in turn, is used to
index arrays which makes it a potential spectre gadget. Fix this by
sanitizing the value assigned to 'ac->ac2_order'. This covers the
following accesses found with the help of smatch:
* fs/ext4/mballoc.c:1896 ext4_mb_simple_scan_group() warn: potential
spectre issue 'grp->bb_counters' [w] (local cap)

The only user is fuse_create_new_entry(), and there it's used to
mitigate the same mkdir/open-by-handle race as in nfs_mkdir().
The same solution applies - unhash the mkdir argument, then
call d_splice_alias() and if that returns a reference to preexisting
alias, dput() and report success. ->mkdir() argument left unhashed
negative with the preexisting alias moved in the right place is just
fine from the ->mkdir() callers point of view.

The patch to fix the case where a lock request was interrupted ended up
changing default handling of errors such as NFS4ERR_DENIED and caused the
client to immediately resend the lock request. Let's do a partial revert
of that request so that the default is now to exit, but change the way
we handle resends to take into account the fact that the user may have
interrupted the request.

The sequencer core module doesn't call some destructors in the error
path of the init code, which may leave some resources.
This patch mainly fix these leaks by calling the destructors
appropriately at alsa_seq_init(). Also the patch brings a few
cleanups along with it, namely:
- Expand the old "if ((err = xxx) < 0)" coding style
- Get rid of empty seq_queue_init() and its caller
- Change snd_seq_info_done() to void
Last but not least, a couple of functions lose __exit annotation since
they are called also in alsa_seq_init().
No functional changes but minor code cleanups.
