Package: tor Version: 0.3.3.7-1 Severity: normal Tags: patch upstream Dear Maintainer,
when trying to run an instance of Tor with a custom config file, e.g. tor -f ~/myconf, it will fail due to a (buggy) seccomp filter: ============================================================ T= 1531579290 (Sandbox) Caught a bad syscall attempt (syscall openat) tor(+0x1a689a)[0x56184d39189a] /lib/x86_64-linux-gnu/libpthread.so.0(open64+0x4b)[0x7f548fb333ab] /lib/x86_64-linux-gnu/libpthread.so.0(open64+0x4b)[0x7f548fb333ab] tor(tor_open_cloexec+0x40)[0x56184d377920] tor(start_writing_to_file+0x17a)[0x56184d38b39a] tor(+0x1a047b)[0x56184d38b47b] tor(+0x1a05c8)[0x56184d38b5c8] tor(or_state_save+0x15b)[0x56184d2a97ab] tor(+0x5497b)[0x56184d23f97b] /usr/lib/x86_64-linux-gnu/libevent-2.1.so.6(+0x229ba)[0x7f5490d549ba] /usr/lib/x86_64-linux-gnu/libevent-2.1.so.6(event_base_loop+0x5a7)[0x7f5490d55537] tor(do_main_loop+0x2b4)[0x56184d2406f4] tor(tor_run_main+0x1025)[0x56184d242bd5] tor(tor_main+0x3a)[0x56184d23b18a] tor(main+0x19)[0x56184d23af19] /lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xe7)[0x7f548f585a87] tor(_start+0x2a)[0x56184d23af6a] The fix [1] mentioned in the discussion of the bug on Tor's bugtracker [2] solves the problem. Regards, Jan PS: I'm unsure whether bugs like this are supposed to be reported here. My apologies if they shouldn't be. However, I figured it will 1) help others encountering the bug and 2) make sure the package maintainer is aware of it.
