Comment (by onirony):
As a side note for why I think this merits whitelisting (unless there's a
security issue with torsocks enabling getdents that I'm not aware of): A
quick Google of the error msg plus the getdents and getdents64 syscall
numbers reveals that a lot of people complain about applications failing
bc of lack of getdents support in torsocks.
Pretty lengthy threads can be found on a number of forums in which people
unsuccessfully guess at why torsocks fails on some system call, to the
point where it seems prudent that we amend the error message to include a
link to some torsocks documentation explaining the nature of the whitelist
system. Most forum threads I found re the error message came to
''incorrect'' conclusions about the cause of the error. But for now,
considering getdents/getdents64 seem to be a very major cause of
application incompatibility I think it's a great candidate for inclusion
in the whitelist.
