2024-12-04fusefrontend: sharedstorage: add file content byte-range locksJakob Unterwurzacher
As we must write complete ciphertext blocks (except at EOF), non-overlapping plaintext writes can overlap in the ciphertext. And because overlapping writes can turn the data into data soup (see TestPoCTornWrite) we serialize them using fcntl locking.

2024-12-04tests/cluster: add TestPoCTornWriteJakob Unterwurzacher
Scary. But explains why TestConcurrentCreate fails. gocryptfs/tests/cluster$ go test -run TestPoCTornWrite --- FAIL: TestPoCTornWrite (0.00s) poc_test.go:210: iteration 214: inconsistent block: d6d6d6d6d6d6d6d6d1d1d1d1d1d1d1d1d1d1d1d1d1d1d1d1d1d1d1d1d1d1d1d1d1d1d1d1d1d1d1d1d1d1 FAIL
2024-12-04fusefrontend: sharedstorage: keep file header on truncateJakob Unterwurzacher
With -sharedstorage, we keep the on-disk file header. Other mounts may have the file ID cached so we cannot mess with it. This makes TestOpenTruncate pass.

2024-12-04tests/cluster: add TestPoCHeaderCreationJakob Unterwurzacher
2024-12-04tests/cluster: add TestConcurrentCreateJakob Unterwurzacher
This exercises the byte-range locks we just added.
2024-12-04fusefrontend: sharedstorage: use byte-range lock on file header creationJakob Unterwurzacher
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.
2024-12-04tests: ignore pidfd in fd leak testJakob Unterwurzacher
This is not a real leak: fd leak in test process? before, after: [0r=/dev/null 3r=/proc/940141/fd 5rw=anon_inode:[eventfd] (filtered: pipe:[2454797], pipe:[2454797], anon_inode:[eventpoll])] [0r=/dev/null 3r=/proc/940141/fd 5rw=anon_inode:[eventfd] 12rw=anon_inode:[pidfd] (filtered: pipe:[2454797], pipe:[2454797], anon_inode:[eventpoll], pipe:[2460158])] Ignore pidfd.
2024-12-04gocryptfs -passwd: fix the tests I just brokeJakob Unterwurzacher
Turns out at least the tests depended on the old behavoir. Fixes d5bd98eb3f4cbfb8dd9d0b2eb64dbff69c3c88b1
2024-12-04gocryptfs -passwd: ignore -extpass and -passfile for new passwordJakob Unterwurzacher
Using the same "-extpass" or "-passfile" for both old and new password makes little sense, and it causes real problems as seen here: https://github.com/rfjakob/gocryptfs/discussions/882 I hope nobody depends on this or I'll have to revert. Fixes https://github.com/rfjakob/gocryptfs/issues/287 Fixes https://github.com/rfjakob/gocryptfs/discussions/882

2024-07-27cli: deduplicate kernel optionsJoker
Merge stock kernel options with user-provided ones before passing to go-fuse. Before: `-ko volname=custom` would result in `-o volname=mountpoint,volname=custom` to macFUSE. After: `-ko volname=custom` would produce `-o volname=custom` with no duplicates. Fixes #854 and #557

We used to present gocryptfs.longname.*.name files for hardlinked files as hardlinked to the kernel (same Node ID) which is wrong. Fix this by using a unique generation number for all nodes, which also fixes possible issues with inode reuse. Basically what 1bc1db620b061aabf59469a5eb4fb60e3e1701a3 did for forward mode with -sharedstorage. Fixes https://github.com/rfjakob/gocryptfs/issues/802
