If slots isn't with a topdown event then moving it is unnecessary. For example {instructions, slots} is re-ordered: $ perf stat -e '{instructions,slots}' -a sleep 1 Performance counter stats for 'system wide': 936,600,825 slots 144,440,968 instructions 1.006061423 seconds time elapsed Which can break tools expecting the command line order to match the printed order. It is necessary to move the slots event first when it appears with topdown events. Add extra checking so that the slots event is only moved in the case of there being a topdown event like: $ perf stat -e '{instructions,slots,topdown-fe-bound}' -a sleep 1 Performance counter stats for 'system wide': 2427568570 slots 300927614 instructions 551021649 topdown-fe-bound 1.001771803 seconds time elapsed Fixes: 94dbfd67 ("perf parse-events: Architecture specific leader override") Reported-by:Kan Liang <kan.liang@linux.intel.com> Signed-off-by:

Generating the version kernel tag relies on "git describe" command to get the latest Linus kernel tag. However, when working from clones of Linus' git we may not have the latest tag. For example, when working on Arnaldo's acme.git, we can have this: $ git branch perf/core $ head -n 5 ../../Makefile | tail -n 4 VERSION = 5 PATCHLEVEL = 17 SUBLEVEL = 0 EXTRAVERSION = -rc3 $ git describe --abbrev=0 --match "v[0-9].[0-9]*" v4.13-rc5 Indeed using tags is a problem as it relies on tags being pulled from Linus' git (and pushed to the clone). In commit a4147f0f ("perf tools: Fix perf version generation") Robert introduced a change to use the kernelversion rule to generate the kernel tag when no git tags are available. However, as mentioned above, the tag we generate may be incorrect, so just always use kernelversion to get the tag (apart from building perf out of tree). Signed-off-by:

Pull btrfs updates from David Sterba: "This contains feature updates, performance improvements, preparatory and core work and some related VFS updates: Features: - encoded read/write ioctls, allows user space to read or write raw data directly to extents (now compressed, encrypted in the future), will be used by send/receive v2 where it saves processing time - zoned mode now works with metadata DUP (the mkfs.btrfs default) - error message header updates: - print error state: transaction abort, other error, log tree errors - print transient filesystem state: remount, device replace, ignored checksum verifications - tree-checker: verify the transaction id of the to-be-written dirty extent buffer Performance improvements for fsync: - directory logging speedups (up to -90% run time) - avoid logging all directory changes during renames (up to -60% run time) - avoid inode logging during rename and link when possible (up to -60% run time) - prepare extents to be logged before locking a log tree path (throughput +7%) - stop copying old file extents when doing a full fsync() - improved logging of old extents after truncate Core, fixes: - improved stale device identification by dev_t and not just path (for devices that are behind other layers like device mapper) - continued extent tree v2 preparatory work - disable features that won't work yet - add wrappers and abstractions for new tree roots - improved error handling - add super block write annotations around background block group reclaim - fix device scanning messages potentially accessing stale pointer - cleanups and refactoring VFS: - allow reflinks/deduplication from two different mounts of the same filesystem - export and add helpers for read/write range verification, for the encoded ioctls" * tag 'for-5.18-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux: (98 commits) btrfs: zoned: put block group after final usage btrfs: don't access possibly stale fs_info data in device_list_add btrfs: add lockdep_assert_held to need_preemptive_reclaim btrfs: verify the tranisd of the to-be-written dirty extent buffer btrfs: unify the error handling of btrfs_read_buffer() btrfs: unify the error handling pattern for read_tree_block() btrfs: factor out do_free_extent_accounting helper btrfs: remove last_ref from the extent freeing code btrfs: add a alloc_reserved_extent helper btrfs: remove BUG_ON(ret) in alloc_reserved_tree_block btrfs: add and use helper for unlinking inode during log replay btrfs: extend locking to all space_info members accesses btrfs: zoned: mark relocation as writing fs: allow cross-vfsmount reflink/dedupe btrfs: remove the cross file system checks from remap btrfs: pass btrfs_fs_info to btrfs_recover_relocation btrfs: pass btrfs_fs_info for deleting snapshots and cleaner btrfs: add filesystems state details to error messages btrfs: deal with unexpected extent type during reflinking btrfs: fix unexpected error path when reflinking an inline extent ... -

This reverts commit 6f98a4bf. It turns out we still can't do this. Way too many platforms that don't have any real source of randomness at boot and no jitter entropy because they don't even have a cycle counter. As reported by Guenter Roeck: "This causes a large number of qemu boot test failures for various architectures (arm, m68k, microblaze, sparc32, xtensa are the ones I observed). Common denominator is that boot hangs at 'Saving random seed:'" This isn't hugely unexpected - we tried it, it failed, so now we'll revert it.

We also correct the SELinux hook implementation so that it returns zero on success. - In addition to a few SELinux mount option parsing fixes, we simplified the parsing by moving it earlier in the process. The logic was that it was unlikely an admin/user would use the new mount API and not have the policy loaded before passing the SELinux options. - Properly fixed the LSM/SELinux/SCTP hooks with the addition of the security_sctp_assoc_established() hook. This work was done in conjunction with the netdev folks and should complete the move of the SCTP labeling from the endpoints to the associations. - Fixed a variety of sparse warnings caused by changes in the "__rcu" markings of some core kernel structures. - Ensure we access the superblock's LSM security blob using the stacking-safe accessors. - Added the ability for the kernel to always allow FIOCLEX and FIONCLEX if the "ioctl_skip_cloexec" policy capability is specified. - Various constifications improvements, type casting improvements, additional return value checks, and dead code/parameter removal. - Documentation fixes" * tag 'selinux-pr-20220321' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux: (23 commits) selinux: shorten the policy capability enum names docs: fix 'make htmldocs' warning in SCTP.rst selinux: allow FIOCLEX and FIONCLEX with policy capability selinux: use correct type for context length selinux: drop return statement at end of void functions security: implement sctp_assoc_established hook in selinux security: add sctp_assoc_established hook selinux: parse contexts for mount options early selinux: various sparse fixes selinux: try to use preparsed sid before calling parse_sid() selinux: Fix selinux_sb_mnt_opts_compat() LSM: general protection fault in legacy_parse_param selinux: fix a type cast problem in cred_init_security() selinux: drop unused macro selinux: simplify cred_init_security selinux: do not discard const qualifier in cast selinux: drop unused parameter of avtab_insert_node selinux: drop cast to same type selinux: enclose macro arguments in parenthesis selinux: declare name parameter of hash_eval const ... -

Pull random number generator updates from Jason Donenfeld: "There have been a few important changes to the RNG's crypto, but the intent for 5.18 has been to shore up the existing design as much as possible with modern cryptographic functions and proven constructions, rather than actually changing up anything fundamental to the RNG's design. So it's still the same old RNG at its core as before: it still counts entropy bits, and collects from the various sources with the same heuristics as before, and so forth. However, the cryptographic algorithms that transform that entropic data into safe random numbers have been modernized. Just as important, if not more, is that the code has been cleaned up and re-documented. As one of the first drivers in Linux, going back to 1.3.30, its general style and organization was showing its age and becoming both a maintenance burden and an auditability impediment. Hopefully this provides a more solid foundation to build on for the future. I encourage you to open up the file in full, and maybe you'll remark, "oh, that's what it's doing," and enjoy reading it. That, at least, is the eventual goal, which this pull begins working toward. Here's a summary of the various patches in this pull: - /dev/urandom and /dev/random now do the same thing, per the patch we discussed on the list. I think this is worth trying out. If it does appear problematic, I've made sure to keep it standalone and revertible without any conflicts. - Fixes and cleanups for numerous integer type problems, locking issues, and general code quality concerns. - The input pool's LFSR has been replaced with a cryptographically secure hash function, which has security and performance benefits alike, and consequently allows us to count entropy bits linearly. - The pre-init injection now uses a real hash function too, instead of an LFSR or vanilla xor. - The interrupt handler's fast_mix() function now uses one round of SipHash, rather than the fake crypto that was there before. - All additions of RDRAND and RDSEED now go through the input pool's hash function, in part to mitigate ridiculous hypothetical CPU backdoors, but more so to have a consistent interface for ingesting entropy that's easy to analyze, making everything happen one way, instead of a potpourri of different ways. - The crng now works on per-cpu data, while also being in accordance with the actual "fast key erasure RNG" design. This allows us to fix several boot-time race complications associated with the prior dynamically allocated model, eliminates much locking, and makes our backtrack protection more robust. - Batched entropy now erases doled out values so that it's backtrack resistant. - Working closely with Sebastian, the interrupt handler no longer needs to take any locks at all, as we punt the synchronized/expensive operations to a workqueue. This is especially nice for PREEMPT_RT, where taking spinlocks in irq context is problematic. It also makes the handler faster for the rest of us. - Also working with Sebastian, we now do the right thing on CPU hotplug, so that we don't use stale entropy or fail to accumulate new entropy when CPUs come back online. - We handle virtual machines that fork / clone / snapshot, using the "vmgenid" ACPI specification for retrieving a unique new RNG seed, which we can use to also make WireGuard (and in the future, other things) safe across VM forks. - Around boot time, we now try to reseed more often if enough entropy is available, before settling on the usual 5 minute schedule. - Last, but certainly not least, the documentation in the file has been updated considerably" * tag 'random-5.18-rc1-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random: (60 commits) random: check for signal and try earlier when generating entropy random: reseed more often immediately after booting random: make consistent usage of crng_ready() random: use SipHash as interrupt entropy accumulator wireguard: device: clear keys on VM fork random: provide notifier for VM fork random: replace custom notifier chain with standard one random: do not export add_vmfork_randomness() unless needed virt: vmgenid: notify RNG of VM fork and supply generation ID ACPI: allow longer device IDs random: add mechanism for VM forks to reinitialize crng random: don't let 644 read-only sysctls be written to random: give sysctl_random_min_urandom_seed a more sensible value random: block in /dev/urandom random: do crng pre-init loading in worker rather than irq random: unify cycles_t and jiffies usage and types random: cleanup UUID handling random: only wake up writers after zap if threshold was passed random: round-robin registers as ulong, not u32 random: clear fast pool, crng, and batches in cpuhp bring up ... -
