sys: Use membar_release/acquire around reference drop. This just goes through my recent reference count membar audit and changes membar_exit to membar_release and membar_enter to membar_acquire -- this should make everything cheaper on most CPUs without hurting correctness, because membar_acquire is generally cheaper than membar_enter.

sys: Membar audit around reference count releases. If two threads are using an object that is freed when the reference count goes to zero, we need to ensure that all memory operations related to the object happen before freeing the object. Using an atomic_dec_uint_nv(&refcnt) == 0 ensures that only one thread takes responsibility for freeing, but it's not enough to ensure that the other thread's memory operations happen before the freeing. Consider: Thread A Thread B obj->foo = 42; obj->baz = 73; mumble(&obj->bar); grumble(&obj->quux); /* membar_exit(); */ /* membar_exit(); */ atomic_dec -- not last atomic_dec -- last /* membar_enter(); */ KASSERT(invariant(obj->foo, obj->bar)); free_stuff(obj); The memory barriers ensure that obj->foo = 42; mumble(&obj->bar); in thread A happens before KASSERT(invariant(obj->foo, obj->bar)); free_stuff(obj); in thread B. Without them, this ordering is not guaranteed. So in general it is necessary to do membar_exit(); if (atomic_dec_uint_nv(&obj->refcnt) != 0) return; membar_enter(); to release a reference, for the `last one out hit the lights' style of reference counting. (This is in contrast to the style where one thread blocks new references and then waits under a lock for existing ones to drain with a condvar -- no membar needed thanks to mutex(9).) I searched for atomic_dec to find all these. Obviously we ought to have a better abstraction for this because there's so much copypasta. This is a stop-gap measure to fix actual bugs until we have that. It would be nice if an abstraction could gracefully handle the different styles of reference counting in use -- some years ago I drafted an API for this, but making it cover everything got a little out of hand (particularly with struct vnode::v_usecount) and I ended up setting it aside to work on psref/localcount instead for better scalability. I got bored of adding #ifdef __HAVE_ATOMIC_AS_MEMBAR everywhere, so I only put it on things that look performance-critical on 5sec review. We should really adopt membar_enter_preatomic/membar_exit_postatomic or something (except they are applicable only to atomic r/m/w, not to atomic_load/store_*, making the naming annoying) and get rid of all the ifdefs.

fix race between wapbl_discard() and wapbl_biodone() on forced unmount on shutdown with slow I/O device wapbl_discard() needs to hold both wl_mtx and bufcache_lock while manipulating wl_entries - the rw lock is not enough, because wapbl_biodone() only takes wl_mtx while removing the finished entry from list wapbl_biodone() must take bufcache_lock before reading we->we_wapbl, so it's blocked until wapbl_discard() finishes, and takes !wl path appropriately this is supposed to fix panic on shutdown: [ 67549.6304123] forcefully unmounting / (/dev/wd0a)... ...

Welcome to 5.99.53! Merge rmind-uvmplock branch: - Reorganize locking in UVM and provide extra serialisation for pmap(9). New lock order: [vmpage-owner-lock] -> pmap-lock. - Simplify locking in some pmap(9) modules by removing P->V locking. - Use lock object on vmobjlock (and thus vnode_t::v_interlock) to share the locks amongst UVM objects where necessary (tmpfs, layerfs, unionfs). - Rewrite and optimise x86 TLB shootdown code, make it simpler and cleaner. Add TLBSTATS option for x86 to collect statistics about TLB shootdowns. - Unify /dev/mem et al in MI code and provide required locking (removes kernel-lock on some ports). Also, avoid cache-aliasing issues. Thanks to Andrew Doran and Joerg Sonnenberger, as their initial patches formed the core changes of this branch.

Set the limit for deallocations in one transaction to a more realistic (and much lower) value. When flushing the log these deallocations will produce new blocks and that may execeed the journal size resulting in a "wapbl_flush: current transaction too big to flush" panic. Seen when removing a large snapshot. Adresses PR #44568 (WAPBL doens't play nice with snapshots).

Use correct offset to block number calculations. Also change access to filesystem blocks to be done by fragment instead of by physical block. Fragments are the fundamental blocks of the filesystem. For a theoretical filesystem that accesses the disk in smaller units than stored in mp->mnt_fs_bshift, the assumption might be wrong. But this will also break other subsystems. The value mp->mnt_dev_bshift which formerly represents the physical sector size is currently only virtual in NetBSD (always DEV_BSIZE).

Problem discovered and patch by dholland@. - If the syncer fails to lazily sync a vnode due to lock contention, retry 1 second later instead of 30 seconds later. - Flush inode atime updates every ~10 seconds (this makes most sense with logging). Presently they didn't hit the disk for read-only files or devices until the file system was unmounted. It would be better to trickle the updates out but that would require more extensive changes. - Fix issues with file system corruption, busy looping and other nasty problems when logging and non-logging file systems are intermixed, with one being the root file system. - For logging, do not flush metadata on an inode-at-a-time basis if the sync has been requested by ioflush. Previously, we could try hundreds of log sync operations a second due to inode update activity, causing the syncer to fall behind and metadata updates to be serialized across the entire file system. Instead, burst out metadata and log flushes at a minimum interval of every 10 seconds on an active file system (happens more often if the log becomes full). Note this does not change the operation of fsync() etc. - With the flush issue fixed, re-enable concurrent metadata updates in vfs_wapbl.c.

Decouple journal operation from replay header by copying the interesting fields into wapbl_replay as opposed to embedding wapbl_wc_header.

Refact wapbl_replay_prescan to use a function for each WAPBL record. Merge wapbl_replay_get_inodes into wapbl_replay_prescan. Change the logic to determine the head: It doesn't make sense to update it if the last inode record seen was not the beginning of the journal, as the beginning of the journal might not be 0, so always update inodeshead.

In wapbl_replay_write just iterate over the hash table and not the transactions. The initial prescan has already sorted out what blocks are in the journal and removed any revoced blocks, so the hash table is authorative.

Move WAPL replay handling from bread() into ufs_strategy. This changes the order of hook processing as the copy-on-write handlers are called after the journal processing. This makes more sense as the journal overwrite is logically part of the disk IO.
