fsnotify: optimize FS_MODIFY events with no ignored masks
fsnotify() treats FS_MODIFY events specially - it does not skip them even if the FS_MODIFY event does not apear in the object's fsnotify mask. This is because send_to_group() checks if FS_MODIFY needs to clear ignored mask of marks. The common case is that an object does not have any mark with ignored mask and in particular, that it does not have a mark with ignored mask and without the FSNOTIFY_MARK_FLAG_IGNORED_SURV_MODIFY flag. Set FS_MODIFY in object's fsnotify mask during fsnotify_recalc_mask() if object has a mark with an ignored mask and without the FSNOTIFY_MARK_FLAG_IGNORED_SURV_MODIFY flag and remove the special treatment of FS_MODIFY in fsnotify(), so that FS_MODIFY events could be optimized in the common case. Call fsnotify_recalc_mask() from fanotify after adding or removing an ignored mask from a mark without FSNOTIFY_MARK_FLAG_IGNORED_SURV_MODIFY or when adding the FSNOTIFY_MARK_FLAG_IGNORED_SURV_MODIFY flag to a mark with ignored mask (the flag cannot be removed by fanotify uapi). Performance results for doing 10000000 write(2)s to tmpfs: vanilla patched without notification mark 25.486+-1.054 24.965+-0.244 with notification mark 30.111+-0.139 26.891+-1.355 So we can see the overhead of notification subsystem has been drastically reduced.

fsnotify: fix merge with parent's ignored mask
fsnotify_parent() does not consider the parent's mark at all unless the parent inode shows interest in events on children and in the specific event. So unless parent added an event to both its mark mask and ignored mask, the event will not be ignored. Fix this by declaring the interest of an object in an event when the event is in either a mark mask or ignored mask.

perf/urgent contains 3 fixups:
- Intel/PT: filters could crash the kernel
- Intel: default disable the PMU for SMM, some new-ish EFI firmware has
started using CPL3 and the PMU CPL filters don't discriminate against
SMM, meaning that CPL3 (userspace only) events now also count EFI/SMM
cycles.
- Fixup for perf_event_attr::sig_data

perf stat: Fix display of grouped aliased events
An event may have a number of uncore aliases that when added to the
evlist are consecutive.
If there are multiple uncore events in a group then
parse_events__set_leader_for_uncore_aliase will reorder the evlist so
that events on the same PMU are adjacent.
The collect_all_aliases function assumes that aliases are in blocks so
that only the first counter is printed and all others are marked merged.
The reordering for groups breaks the assumption and so all counts are
printed.
This change removes the assumption from collect_all_aliases
that the events are in blocks and instead processes the entire evlist.

perf synthetic-events: Return error if procfs isn't mounted for PID namespaces
For perf recording, it retrieves process info by iterating nodes in proc fs. If we run perf in a non-root PID namespace with command: # unshare --fork --pid perf record -e cycles -a -- test_program ... in this case, unshare command creates a child PID namespace and launches perf tool in it, but the issue is the proc fs is not mounted for the non-root PID namespace, this leads to the perf tool gathering process info from its parent PID namespace. We can use below command to observe the process nodes under proc fs: # unshare --pid --fork ls /proc 1 137 1968 2128 3 342 48 62 78 crypto kcore net uptime 10 138 2 2142 30 35 49 63 8 devices keys pagetypeinfo version 11 139 20 2143 304 36 50 64 82 device-tree key-users partitions vmallocinfo 12 14 2011 22 305 37 51 65 83 diskstats kmsg self vmstat 128 140 2038 23 307 39 52 656 84 driver kpagecgroup slabinfo zoneinfo 129 15 2074 24 309 4 53 67 9 execdomains kpagecount softirqs 13 16 2094 241 31 40 54 68 asound fb kpageflags stat 130 164 2096 242 310 41 55 69 buddyinfo filesystems loadavg swaps 131 17 2098 25 317 42 56 70 bus fs locks sys 132 175 21 26 32 43 57 71 cgroups interrupts meminfo sysrq-trigger 133 179 2102 263 329 44 58 75 cmdline iomem misc sysvipc 134 1875 2103 27 330 45 59 76 config.gz ioports modules thread-self 135 19 2117 29 333 46 6 77 consoles irq mounts timer_list 136 1941 2121 298 34 47 60 773 cpuinfo kallsyms mtd tty So it shows many existed tasks, since unshared command has not mounted the proc fs for the new created PID namespace, it still accesses the proc fs of the root PID namespace. This leads to two prominent issues: - Firstly, PID values are mismatched between thread info and samples. The gathered thread info are coming from the proc fs of the root PID namespace, but samples record its PID from the child PID namespace. - The second issue is profiled program 'test_program' returns its forked PID number from the child PID namespace, perf tool wrongly uses this PID number to retrieve the process info via the proc fs of the root PID namespace. To avoid issues, we need to mount proc fs for the child PID namespace with the option '--mount-proc' when use unshare command: # unshare --fork --pid --mount-proc perf record -e cycles -a -- test_program Conversely, when the proc fs of the root PID namespace is used by child namespace, perf tool can detect the multiple PID levels and nsinfo__is_in_root_namespace() returns false, this patch reports error for this case: # unshare --fork --pid perf record -e cycles -a -- test_program Couldn't synthesize bpf events. Perf runs in non-root PID namespace but it tries to gather process info from its parent PID namespace. Please mount the proc file system properly, e.g. add the option '--mount-proc' for unshare command.

Merge tag 'vfs-5.17-fixes-2' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux
Pull vfs fixes from Darrick Wong:
"I was auditing the sync_fs code paths recently and noticed that most
callers of ->sync_fs ignore its return value (and many implementations
never return nonzero even if the fs is broken!), which means that
internal fs errors and corruption are not passed up to userspace
callers of syncfs(2) or FIFREEZE. Hence fixing the common code and
XFS, and I'll start working on the ext4/btrfs folks if this is merged.
Summary:
- Fix a bug where callers of ->sync_fs (e.g. sync_filesystem and
syncfs(2)) ignore the return value.
- Fix a bug where callers of sync_filesystem (e.g. fs freeze) ignore
the return value.
- Fix a bug in XFS where xfs_fs_sync_fs never passed back error
returns"
* tag 'vfs-5.17-fixes-2' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux:
xfs: return errors in xfs_fs_sync_fs

Pull random number generator fixes from Jason Donenfeld:
"For this week, we have:
- A fix to make more frequent use of hwgenerator randomness, from
Dominik.
- More cleanups to the boot initialization sequence, from Dominik.
- A fix for an old shortcoming with the ZAP ioctl, from me.
- A workaround for a still unfixed Clang CFI/FullLTO compiler bug,
from me. On one hand, it's a bummer to commit workarounds for
experimental compiler features that have bugs. But on the other, I
think this actually improves the code somewhat, independent of the
bug. So a win-win"

random: only call crng_finalize_init() for primary_crng
crng_finalize_init() returns instantly if it is called for another pool than primary_crng. The test whether crng_finalize_init() is still required can be moved to the relevant caller in crng_reseed(), and crng_need_final_init can be reset to false if crng_finalize_init() is called with workqueues ready. Then, no previous callsite will call crng_finalize_init() unless it is needed, and we can get rid of the superfluous function parameter.

random: wake up /dev/random writers after zap
When account() is called, and the amount of entropy dips below random_write_wakeup_bits, we wake up the random writers, so that they can write some more in. However, the RNDZAPENTCNT/RNDCLEARPOOL ioctl sets the entropy count to zero -- a potential reduction just like account() -- but does not unblock writers. This commit adds the missing logic to that ioctl to unblock waiting writers. Reviewed-by: Dominik Brodowski <linux@dominikbrodowski.net> Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com> |

random: continually use hwgenerator randomness
The rngd kernel thread may sleep indefinitely if the entropy count is kept above random_write_wakeup_bits by other entropy sources. To make best use of multiple sources of randomness, mix entropy from hardware RNGs into the pool at least once within CRNG_RESEED_INTERVAL. Cc: Herbert Xu <herbert@gondor.apana.org.au> Cc: Jason A.

lib/crypto: blake2s: avoid indirect calls to compression function for Clang CFI
blake2s_compress_generic is weakly aliased by blake2s_compress. The
current harness for function selection uses a function pointer, which is
ordinarily inlined and resolved at compile time. But when Clang's CFI is
enabled, CFI still triggers when making an indirect call via a weak
symbol. This seems like a bug in Clang's CFI, as though it's bucketing
weak symbols and strong symbols differently. It also only seems to
trigger when "full LTO" mode is used, rather than "thin LTO".

Nonetheless, the function pointer method isn't so terrific anyway, so
this patch replaces it with a simple boolean, which also gets inlined
away. This successfully works around the Clang bug.
In general, I'm not too keen on all of the indirection involved here; it
clearly does more harm than good. Hopefully the whole thing can get
cleaned up down the road when lib/crypto is overhauled more
comprehensively. But for now, we go with a simple bandaid.
