We additionally need to be going inconsistent if passed an invalid snapshot ID; that patch will need more thorough testing. Reported-by: syzbot+1c9fca23fe478633b305@syzkaller.appspotmail.com Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

We can't disallow unknown data_types in verify() - we have to preserve them unchanged for backwards compat; that means we have to add a few more guards. Reported-by: syzbot+249018ea545364f78d04@syzkaller.appspotmail.com Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

Since commit a2ad63da ("VFS: add FMODE_CAN_ODIRECT file flag") file systems can just set the FMODE_CAN_ODIRECT flag at open time instead of wiring up a dummy direct_IO method to indicate support for direct I/O. Do that for bcachefs so that noop_direct_IO can eventually be removed. Similar to commit b2943499 ("xfs: set FMODE_CAN_ODIRECT instead of a dummy direct_IO method").

Pull bcachefs updates from Kent Overstreet: - More safety fixes, primarily found by syzbot - Run the upgrade/downgrade paths in nochnages mode. Nochanges mode is primarily for testing fsck/recovery in dry run mode, so it shouldn't change anything besides disabling writes and holding dirty metadata in memory. The idea here was to reduce the amount of activity if we can't write anything out, so that bringing up a filesystem in "super ro" mode would be more lilkely to work for data recovery - but norecovery is the correct option for this. - btree_trans->locked; we now track whether a btree_trans has any btree nodes locked, and this is used for improved assertions related to trans_unlock() and trans_relock(). We'll also be using it for improving how we work with lockdep in the future: we don't want lockdep to be tracking individual btree node locks because we take too many for lockdep to track, and it's not necessary since we have a cycle detector. - Trigger improvements that are prep work for online fsck - BTREE_TRIGGER_check_repair; this regularizes how we do some repair work for extents that goes with running triggers in fsck, and fixes some subtle issues with transaction restarts there. - bch2_snapshot_equiv() has now been ripped out of fsck.c; snapshot equivalence classes are for when snapshot deletion leaves behind redundant snapshot nodes, but snapshot deletion now cleans this up right away, so the abstraction doesn't need to leak. - Improvements to how we resume writing to the journal in recovery. The code for picking the new place to write when reading the journal is greatly simplified and we also store the position in the superblock for when we don't read the journal; this means that we preserve more of the journal for list_journal debugging. - Improvements to sysfs btree_cache and btree_node_cache, for debugging memory reclaim. - We now detect when we've blocked for 10 seconds on the allocator in the write path and dump some useful info. - Safety fixes for devices references: this is a big series that changes almost all device lookups to properly check if the device exists and take a reference to it. Previously we assumed that if a bkey exists that references a device then the device must exist, and this was enforced in .invalid methods, but this was incorrect because it meant device removal relied on accounting being correct to not leave keys pointing to invalid devices, and that's not something we can assume. Getting the "pointer to invalid device" checks out of our .invalid() methods fixes some long standing device removal bugs; the only outstanding bug with device removal now is a race between the discard path and deleting alloc info, which should be easily fixed. - The allocator now prefers not to expand the new member_info.btree_allocated bitmap, meaning if repair ever requires scanning for btree nodes (because of a corrupt interior nodes) we won't have to scan the whole device(s). - New coding style document, which among other things talks about the correct usage of assertions * tag 'bcachefs-2024-05-19' of https://evilpiepirate.org/git/bcachefs: (155 commits) bcachefs: add no_invalid_checks flag bcachefs: add counters for failed shrinker reclaim bcachefs: Fix sb_field_downgrade validation bcachefs: Plumb bch_validate_flags to sb_field_ops.validate() bcachefs: s/bkey_invalid_flags/bch_validate_flags bcachefs: fsync() should not return -EROFS bcachefs: Invalid devices are now checked for by fsck, not .invalid methods bcachefs: kill bch2_dev_bkey_exists() in bch2_check_fix_ptrs() bcachefs: kill bch2_dev_bkey_exists() in bch2_read_endio() bcachefs: bch2_dev_get_ioref() checks for device not present bcachefs: bch2_dev_get_ioref2(); io_read.c bcachefs: bch2_dev_get_ioref2(); debug.c bcachefs: bch2_dev_get_ioref2(); journal_io.c bcachefs: bch2_dev_get_ioref2(); io_write.c bcachefs: bch2_dev_get_ioref2(); btree_io.c bcachefs: bch2_dev_get_ioref2(); backpointers.c bcachefs: bch2_dev_get_ioref2(); alloc_background.c bcachefs: for_each_bset() declares loop iter bcachefs: Move BCACHEFS_STATFS_MAGIC value to UAPI magic.h bcachefs: Improve sysfs internal/btree_cache ...

Beyond those big diffs there's the usual updates to various clk drivers for incorrect parent descriptions or mising MODULE_DEVICE_TABLE()s, etc. Nothing in particular stands out as super interesting here.

Pull tracing tool updates from Steven Rostedt: "Specific for timerlat: - Improve the output of timerlat top by adding a missing \n, and by avoiding printing color-formatting characters where they are translated to regular characters. - Improve timerlat auto-analysis output by replacing '\t' with spaces to avoid copy-and-paste issues when reporting problems. - Make the user-space (-u) option the default, as it is the most complete test. Add a -k option to use the in-kernel workload. - On timerlat top and hist, add a summary with the overall results. For instance, the minimum value for all CPUs, the overall average and the maximum value from all CPUs. - timerlat hist was printing initial values (i.e., 0 as max, and ~0 as min) if the trace stopped before the first Ret-User event. This problem was fixed by printing the " - " no value string to the output if that was the case. For all RTLA tools: - Add a --warm-up <seconds> option, allowing the workload to run for <seconds> before starting to collect results. - Add a --trace-buffer-size option, allowing the user to set the tracing buffer size for -t option. This option is mainly useful for reducing the trace file.

But the parsing expected at least one space to be there (which was incorrect). Fix the reading of the string to handle fields separated by semicolons but no space between them. This does extend the API sightly as now "field;field" will now be parsed and not cause an error. But it should not cause any regressions as no logic should expect it to fail. Note, that the logic that parses the event fields to create the trace_event works with no spaces after the semi-colon. It is the logic that tests against existing events that is inconsistent. This causes registering an event without using spaces to succeed if it doesn't exist, but makes the same call that tries to register to the same event, but doesn't use spaces, fail. * tag 'trace-user-events-v6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: selftests/user_events: Add non-spacing separator check tracing/user_events: Fix non-spaced field matching

Merge tag 'trace-ringbuffer-v6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing ring buffer updates from Steven Rostedt: "Add ring_buffer memory mappings. The tracing ring buffer was created based on being mostly used with the splice system call. It is broken up into page ordered sub-buffers and the reader swaps a new sub-buffer with an existing sub-buffer that's part of the write buffer. It then has total access to the swapped out sub-buffer and can do copyless movements of the memory into other mediums (file system, network, etc). The buffer is great for passing around the ring buffer contents in the kernel, but is not so good for when the consumer is the user space task itself. A new interface is added that allows user space to memory map the ring buffer. It will get all the write sub-buffers as well as reader sub-buffer (that is not written to). It can send an ioctl to change which sub-buffer is the new reader sub-buffer. The ring buffer is read only to user space. It only needs to call the ioctl when it is finished with a sub-buffer and needs a new sub-buffer that the writer will not write over. A self test program was also created for testing and can be used as an example for the interface to user space. The libtracefs (external to the kernel) also has code that interacts with this, although it is disabled until the interface is in a official release. It can be enabled by compiling the library with a special flag. This was used for testing applications that perform better with the buffer being mapped. Memory mapped buffers have limitations. The main one is that it can not be used with the snapshot logic. If the buffer is mapped, snapshots will be disabled. If any logic is set to trigger snapshots on a buffer, that buffer will not be allowed to be mapped" * tag 'trace-ringbuffer-v6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: ring-buffer: Add cast to unsigned long addr passed to virt_to_page() ring-buffer: Have mmapped ring buffer keep track of missed events ring-buffer/selftest: Add ring-buffer mapping test Documentation: tracing: Add ring-buffer mapping tracing: Allow user-space mapping of the ring-buffer ring-buffer: Introducing ring-buffer mapping functions ring-buffer: Allocate sub-buffers with __GFP_COMP

Adjust the initialization sequence of KSZ88x3 switches to enable 802.1p priority control on Port 2 before configuring Port 1. This change ensures the apptrust functionality on Port 1 operates correctly, as it depends on the priority settings of Port 2. The prior initialization sequence incorrectly configured Port 1 first, which could lead to functional discrepancies.
