13d593a5 - Fix a race in fusefs that can corrupt a file's size.

Mon, 29 Nov 2021 02:17:34 +0000

Fix a race in fusefs that can corrupt a file's size.VOPs like VOP_SETATTR can change a file's size, with the vnodeexclusively locked. But VOPs like VOP_LOOKUP look up the file size fromthe server without the vnode locked. So a race is possible. Forexample:1) One thread calls VOP_SETATTR to truncate a file. It locks the vnode and sends FUSE_SETATTR to the server.2) A second thread calls VOP_LOOKUP and fetches the file's attributes from the server. Then it blocks trying to acquire the vnode lock.3) FUSE_SETATTR returns and the first thread releases the vnode lock.4) The second thread acquires the vnode lock and caches the file's attributes, which are now out-of-date.Fix this race by recording a timestamp in the vnode of the last timethat its filesize was modified. Check that timestamp during VOP_LOOKUPand VFS_VGET. If it's newer than the time at which FUSE_LOOKUP wasissued to the server, ignore the attributes returned by FUSE_LOOKUP.PR: 259071Reported by: Agata Reviewed by: pfgMFC after: 2 weeksDifferential Revision: https://reviews.freebsd.org/D33158 List of files: /freebsd-14.2/tests/sys/fs/fusefs/Makefile

7cc42f6d - Do a sweep and remove most WARNS=6 settings

Thu, 01 Oct 2020 01:10:51 +0000

Do a sweep and remove most WARNS=6 settingsRepeating the default WARNS here makes it slightly more difficult toexperiment with default WARNS changes, e.g. if we did something absolutelybananas and introduced a WARNS=7 and wanted to try lifting the default tothat.Drop most of them; there is one in the blake2 kernel module, but I suspectit should be dropped -- the default WARNS in the rest of the build doesn'tcurrently apply to kernel modules, and I haven't put too much thought intowhether it makes sense to make it so.

b0ecfb42 - fusefs: avoid cache corruption with buggy fuse servers

Wed, 11 Mar 2020 04:29:45 +0000

fusefs: avoid cache corruption with buggy fuse serversThe FUSE protocol allows the client (kernel) to cache a file's size, if theserver (userspace daemon) allows it. A well-behaved daemon obviously shouldnot change a file's size while a client has it cached. But a buggy daemonmight. If the kernel ever detects that that has happened, then it shouldinvalidate the entire cache for that file. Previously, we would not onlycache stale data, but in the case of a file extension while we had the sizecached, we accidentally extended the cache with zeros.PR: 244178Reported by: Ben RUBSON Reviewed by: cemMFC after: 2 weeksDifferential Revision: https://reviews.freebsd.org/D24012 List of files: /freebsd-14.2/tests/sys/fs/fusefs/Makefile

Report large valuesfor runp and runb in order to maximize read clustering and minimize upcalls,even if we don't know the true layout.The major result of this change is that sequential reads to FUSE files willnow usually happen 128KB at a time instead of 64KB.Sponsored by: The FreeBSD Foundation List of files: /freebsd-14.2/tests/sys/fs/fusefs/Makefile

a87e0831 - fusefs: WIP fixing writeback cacheing

Tue, 11 Jun 2019 16:32:33 +0000

fusefs: WIP fixing writeback cacheingThe current "writeback" cache mode, selected by thevfs.fusefs.data_cache_mode sysctl, doesn't do writeback cacheing at all. Itmerely goes through the motions of using buf(9), but then writes everybuffer synchronously. This commit:* Enables delayed writes when the sysctl is set to writeback cacheing* Fixes a cache-coherency problem when extending a file whose last page has just been written.* Removes the "sync" mount option, which had been set unconditionally.* Adjusts some SDT probes* Adds several new tests that mimic what fsx does but with more control and without a real file system. As I discover failures with fsx, I add regression tests to this file.* Adds a test that ensures we can append to a file without reading any data from it.This change is still incomplete. Clustered writing is not yet supported,and there are frequent "panic: vm_fault_hold: fault on nofault entry" panicsthat I need to fix.Sponsored by: The FreeBSD Foundation List of files: /freebsd-14.2/tests/sys/fs/fusefs/Makefile

fusefs: Make fuse file systems NFS-exportableThis commit adds the VOPs needed by userspace NFS servers (tested withnet/unfs3). More work is needed to make the in-kernel nfsd work, because ofits stateless nature. It doesn't open files prior to doing I/O. Also, theNFS-related VOPs currently ignore the entry cache.Sponsored by: The FreeBSD Foundation List of files: /freebsd-14.2/tests/sys/fs/fusefs/Makefile
