Comment (by Jigsaw52):
I made a small program which uses the same code as tor to setup seccomp
rules and then opens a file and I get the same behavior as I do with tor
(crash before the #25440 fix, success after). It also prints the pseudo-
code for the rules generated by libseccomp.
The code is here: https://pastebin.com/zQz1sf22
Compile with: gcc test.c -o test -l seccomp
Run without arguments to use the rule after the #25440 fix: ./test
Run with any arguments to use the rule before the #25440 fix: ./test foo
If someone affected by this, could run the program with and without
arguments and post both outputs maybe that could help finding out whats
different between our systems.
