fusefrontend: expose birth time via statx

2026-07-22T19:57:57+00:00

Forward the backing filesystem's STATX_BTIME on Linux while preserving existing metadata translations and fallback behavior. On Linux 6.6 and newer, this allows statx consumers such as GNU stat to report birth time when the backing filesystem provides it. Older kernels and backing filesystems without birth-time support retain the existing behavior. No on-disk format change or migration is required. Reverse mode remains unchanged. Fixes #868. Related context: #732

fusefrontend: sharedstorage: use byte-range lock on file header creation

2026-07-16T20:07:54+00:00

Multiple host writing to the same empty file at the same time could have overwritten each other's newly created file header, leading to data corruption. Fix the race by placing a byte-range lock on the file when creating the file header.

Added basic support for FreeBSD.

Freebsd-support: Change bash shebang to use /usr/bin/env Freebsd-support: Fix go vet "undefined" fixes when running make ci freebsd: stub xattr functions /proc/PID/fd does not exist on freebsd. freebsd-support: modify FchmodatNofollow for FreeBSD FreeBSD supports the Fchmodat system call, with the AT_SYMLINK_NOFOLLOW flag. FchmodatNofollow has been modified to use this system call and flag. freebsd-support: PR changes and fixes * Functions in fusefrontend_reverse/node_xattr_freebsd.go have been stubbed for now. * asuser_freebsd.go updated to only run f() when context is nil; otherwise log a warning and return an error. * emulate.go build flags updated, and FreeBSD specific version added. * sys_freebsd.go bug in Renameat2 with RENAME_EXCHANGE flag fixed. FreeBSD does not support atomic file swapping, so this flag now returns an error. * unix2syscall and atime is identical between FreeBSD and Darwin, updated filenames so Go will build the file for FreeBSD and Mac OS. freebsd-support: Addressed more PR comments and fixed build tags

darwin: syscallcompat: Openat: use O_SYMLINK

2026-02-09T20:20:13+00:00

Also add tests that opening a symlink (using unix.O_PATH | unix.O_NOFOLLOW) works. https://github.com/rfjakob/gocryptfs/issues/993

Fix all staticcheck errors in gocryptfs codebase

This fix properly handles nil pointers by using unix.UTIME_OMIT while still using the non-deprecated unix.TimeToTimespec function.

It's only used there, so move it.
