Unsupported syscall number 220 (getdents64)
Using torsocks with the patch from legacy/trac#28861 (moved) reportbug shows this warning:
WARNING torsocks[7469]: [syscall] Unsupported syscall number 220. Denying the call (in tsocks_syscall() at syscall.c:568)
According to the syscall table this is
220 i386 getdents64 sys_getdents64 compat_sys_getdents64 I assume it wouldn't leak information over the internet, but not sure.
