It passes *most of the time*. If it fails, it's like this, and the reason is that there is no fcntl locks in the READ path yet. gocryptfs/tests/cluster$ go test -run TestClusterConcurrentRW -v === RUN TestClusterConcurrentRW doRead 2895433: corrupt block #0: cipher: message authentication failed doRead 2895433: corrupt block #0: cipher: message authentication failed doRead 2895433: corrupt block #0: cipher: message authentication failed cluster_test.go:98: readThread iteration 9165: ReadAt failed: read /var/tmp/gocryptfs-test-parent-1026/3021427391/TestClusterConcurrentRW.366469887.mnt1/foo: input/output error --- FAIL: TestClusterConcurrentRW (0.40s) FAIL exit status 1 FAIL github.com/rfjakob/gocryptfs/v2/tests/cluster 0.406s 2026-07-16T20:07:54+00:00 Jakob Unterwurzacher 2023-06-09T12:33:07+00:00 urn:sha1:e5e594829c7f9bb71cd80ef055c212e09658457a 2026-07-16T20:07:54+00:00 Jakob Unterwurzacher 2023-06-09T05:50:11+00:00 urn:sha1:e16b80c01d655b1fce26183ca3ca72059472d494 2026-07-16T20:07:54+00:00 Jakob Unterwurzacher 2023-06-08T13:50:05+00:00 urn:sha1:2ca5ba9e69bccce27638fa0525cc5f66837dc047 Scary.

Fix the race by placing a byte-range lock on the file when creating the file header.
