Crash after file writing using gocrypts

[libor13]

We are using gocryptfs with fuse-t version 1.0.33 MacOS Sonoma 14.2.1 When trying to change an office document stored on a virtual disk, the process freezes and after a while crashes and restarts the entire MacOS. I am attaching the crash log:

Does it happen on older OSes? Do you have a reliable way to reproduce it and send me instructions? PS: It seems to be related to this https://github.com/macos-fuse-t/fuse-t/issues/45.

[libor13]

I tested on MacOS Big Sur 11.7.8 now and everything seems ok.

[libor13]

Instruction for reproduce crash:

Environment: MacOS Sonoma 14.2.1 (Intel processor) FUSE-T 1.0.33 gocryptfs 2.3 with forked macos-fuse-t/go-fuse

1. Create virtual disk gocryptfs -init /tmp/secure

2. Mount virtual disk gocryptfs /tmp/secure $HOME/mnt

3. Create MS Word docx document on virtual disk and work with it - save, close, open .... While saving the docx, one or more temporary folders are displayed and deleted again on virtual drive, for example with name name.docx.sb-86e266ea-2G7Zgn Randomly during working with docx computer crashes and restarts. (crash report in attachment) panic-full-2024-01-03-120833.0003.ips.zip

After restart folder /tmp/secure will disappear.

[macos-fuse-t]

I wasn't able to reproduce your crash by following the instructions but I encourage you to fill a bug report with apple. Mention that a crash happens when you try to save a word doc to an NFS mounted folder. Unfortunately I'm powerless to resolve such issues because it caused by a sh*tty macOS kernel code and all my previous bug reports got silently ignored.

[libor13]

I installed version 1.0.34 and it seems that saving the docx file works without problems. Thanks

[macos-fuse-t]

I'm in doubt that 1.0.34 has any effect on this. Nevertheless closing this for now, you're welcome to re-open if needed
