weasel reported the following sandxbox warnings on his relay: ``` (Sandbox) Caught a bad syscall attempt (syscall eventfd2) /usr/bin/tor(+0x1328b6)[0x7f71180d18b6] /lib/x86_64-linux-gnu/libc.so.6(eventfd+0xd)[0x7f711649e2fd] /lib/x86_64-linux-gnu/libc.so.6(eventfd+0xd)[0x7f711649e2fd] /usr/bin/tor(alert_sockets_create+0xec)[0x7f71180bef9c] ``` ``` (Sandbox) Caught a bad syscall attempt (syscall open) /usr/bin/tor(+0x1328b6)[0x7f653db158b6] /lib/x86_64-linux-gnu/libpthread.so.0(open64+0x10)[0x7f653c3b81d0] /lib/x86_64-linux-gnu/libpthread.so.0(open64+0x10)[0x7f653c3b81d0] /usr/bin/tor(tor_open_cloexec+0x40)[0x7f653daff5e0] /usr/bin/tor(start_writing_to_file+0xf2)[0x7f653db10732] /usr/bin/tor(+0x12d89b)[0x7f653db1089b] /usr/bin/tor(+0x12d9e8)[0x7f653db109e8] /usr/bin/tor(crypto_pk_write_private_key_to_filename+0xcb)[0x7f653db1f57b] ``` We should probably test the sandbox more thoroughly on relay-mode. Here is the torrc used (to reproduce this): ``` Sandbox 1 PublishServerDescriptor 0 OrPort 9031 ```
