Package: file
Version: 1:5.37-4
Severity: normal

With seccomp enabled, --mime-type is no longer working on arm64.  It
still works on other architectures.

Looking at straces, it seems to be because arm64 is using fsaccessat()
instead of access(). (It's my understanding that arm64 doesn't implement
access()).

Is it possible/reasonable to adjust the seccomp rules to allow
fsaccessat() to restore this functionality on arm64 and bring it back in
line with the other architectures?


To reproduce on sid:

/usr/bin/file --mime-type '/usr/share/icons/hicolor/48x48/apps/xterm.png'

On arm64 this produces "bad system call"

On other archs this produces the expected output, including mimetype.


I have also attached the aforementioned sample straces for amd64, arm64
when failing, and arm64 when run (successfully) with --no-sandbox.

Best regards,

Bill
