2023-04-26nfsd: allow reaping files still under writebackJeff Layton
On most filesystems, there is no reason to delay reaping an nfsd_file just because its underlying inode is still under writeback. nfsd just relies on client activity or the local flusher threads to do writeback. The main exception is NFS, which flushes all of its dirty data on last close. Add a new EXPORT_OP_FLUSH_ON_CLOSE flag to allow filesystems to signal that they do this, and only skip closing files under writeback on such filesystems. Also, remove a redundant NULL file pointer check in nfsd_file_check_writeback, and clean up nfs's export op flag definitions.

2023-04-26nfsd: NFSD_FILE_KEY_INODE only needs to find GC'ed entriesJeff Layton
Since v4 files are expected to be long-lived, there's little value in closing them out of the cache when there is conflicting access. Change the comparator to also match the gc value in the key.

2023-04-26net: phy: hide the PHYLIB_LEDS knobPaolo Abeni
commit 4bb7aac70b5d ("net: phy: fix circular LEDS_CLASS dependencies") solved a build failure, but introduces a new config knob with a default 'y' value: PHYLIB_LEDS. The latter is against the current new config policy. The exception was raised to allow the user to catch bad configurations without led support. Anyway the current definition of PHYLIB_LEDS does not fit the above goal: if LEDS_CLASS is disabled, the new config will be available only with PHYLIB disabled, too. Hide the mentioned config, to preserve the randconfig testing done so far, while respecting the mentioned policy.

When event enablement changes, user_events attempts to update a bit in the user process. If a fault is hit, an attempt to fault-in the page and the write is retried if the page made it in. While this normally requires a couple attempts, it is possible a bad user process could attempt to cause infinite loops. Ensure fault-in attempts either sync or async are limited to a max of 10 attempts for each update. When the max is hit, return -EFAULT so another attempt is not made in all cases.

2023-04-25tracing/user_events: Prevent same address and bit per processBeau Belgrave
User processes register an address and bit pair for events. If the same address and bit pair are registered multiple times in the same process, it can cause undefined behavior when events are enabled/disabled. When more than one are used, the bit could be turned off by another event being disabled, while the original event is still enabled. Prevent undefined behavior by checking the current mm to see if any event has already been registered for the address and bit pair. Return EADDRINUSE back to the user process if it's already being used. Update ftrace self-test to ensure this occurs properly.

2023-04-25seq_buf: Add seq_buf_do_printk() helperSergey Senozhatsky
Sometimes we use seq_buf to format a string buffer, which we then pass to printk(). However, in certain situations the seq_buf string buffer can get too big, exceeding the PRINTKRB_RECORD_MAX bytes limit, and causing printk() to truncate the string. Add a new seq_buf helper. This helper prints the seq_buf string buffer line by line, using \n as a delimiter, rather than passing the whole string buffer to printk() at once.

2023-04-25tracing: Fix print_fields() for __dyn_loc/__rel_locBeau Belgrave
Both print_fields() and print_array() do not handle if dynamic data ends at the last byte of the payload for both __dyn_loc and __rel_loc field types. For __rel_loc, the offset was off by 4 bytes, leading to incorrect strings and data being printed out. In print_array() the buffer pos was missed from being advanced, which results in the first payload byte being used as the offset base instead of the field offset. Advance __rel_loc offset by 4 to ensure correct offset and advance pos to the field offset to ensure correct data is displayed when printing arrays. Change >= to > when checking if data is in-bounds, since it's valid for dynamic data to include the last byte of the payload. Example outputs for event format: field:unsigned short common_type; offset:0; size:2; signed:0; field:unsigned char common_flags; offset:2; size:1; signed:0; field:unsigned char common_preempt_count; offset:3; size:1; signed:0; field:int common_pid; offset:4; size:4; signed:1; field:__rel_loc char text[]; offset:8; size:4; signed:1; Output before: tp_rel_loc: text=<OVERFLOW> Output after: tp_rel_loc: text=Test Link: https://lkml.kernel.org/r/20230419214140.4158-3-beaub@linux.microsoft.com Fixes: 80a76994b2d8 ("tracing: Add "fields" option to show raw trace event fields") Reported-by: Doug Cook <dcook@linux.microsoft.com> Signed-off-by: Beau Belgrave <beaub@linux.microsoft.com> Signed-off-by: Steven Rostedt (Google) <rostedt@goodmis.org>

git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap Pull regmap updates from Mark Brown: "This is a much bigger change for regmap than is normal, the main things being the addition of some KUnit coverage and a maple tree based register cache which longer term is likely to replace the rbtree cache except possibly for very small register maps. While it's complete overkill for most applications the code for maple trees is there and there are some larger, sparser devices where the data structure is a better fit. The maple tree support is still a work in progress but already useful, there's some conversions of drivers ready to go after the merge window. Summary: - Support for shifting register addresses up as well as down, there's a use cases with memory mapped MDIO. - Refactoring of the type configuration in regmap-irq to allow access to driver data in the handler, needed by some GPIO devices. - Some initial KUnit coverage, the bulk of the driver facing API is covered but there's holes and things like the data marshalling for bytestream buses are just not covered in the slightest. - Removal of the compressed cache type, it had zero users and was getting in the way of KUnit. - Addition of a maple tree based register cache, there's more work to do but it's already useful for some devices with a flatter data structure than rbtree and getting to use all the optimisation work Liam is doing" * tag 'regmap-v6.4' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap: regmap: allow upshifting register addresses before performing operations regmap: Pass irq_drv_data as a parameter for set_type_config() regmap: Use mas_walk() instead of mas_find() regmap: Fix double unlock in the maple cache regmap: Add maple tree based register cache regmap: Factor out single value register syncing regmap: Add some basic kunit tests regmap: Add RAM backed register map regmap: Removed compressed cache support regmap: Support paging for buses with reg_read()/reg_write() regmap: Clarify error for unknown cache types regmap: Handle sparse caches in the default sync regmap: add a helper to translate the register address regmap: cache: Silence checkpatch warning regmap: cache: Return error in cache sync operations for REGCACHE_NONE regmap-irq: Place kernel doc of struct regmap_irq_chip in order regmap-irq: Add no_status support regmap: sdw: Remove 8-bit value size restriction regmap: sdw: Update misleading comment

2023-04-25rtla/timerlat: Add auto-analysis only optionDaniel Bristot de Oliveira
Parsing and formating timerlat data might consume a reasonable amount of CPU time on very large systems, or when timerlat has a too short period. Add an option to run timerlat with auto-analysis enabled while skipping the statistics parsing. In this mode, rtla timerlat periodically checks if the tracing is on, going to sleep waiting for the stop tracing condition to stop tracing, or for the tracing session to finish. If the stop tracing condition is hit, the tool prints the auto analysis. Otherwise, the tool prints the max observed latency and exit. The max observed latency is captured via tracing_max_latency.

Since its deprecation in 6.2 I've seen no complaints so hopefully SLUB_(TINY) works well for everyone and we can proceed. Besides the code cleanup, the main immediate benefit will be allowing kfree() family of function to work on kmem_cache_alloc() objects, which was incompatible with SLOB. This includes kfree_rcu() which had no kmem_cache_free_rcu() counterpart yet and now it shouldn't be necessary anymore.
