MIPS: scall: Always run the seccomp syscall filters

2015-10-04T10:10:56+00:00

The MIPS syscall handler code used to return -ENOSYS on invalid
syscalls. Whilst this is expected, it caused problems for seccomp
filters because the said filters never had the change to run since
the code returned -ENOSYS before triggering them. This caused
problems on the chromium testsuite for filters looking for invalid
syscalls. This has now changed and the seccomp filters are always
run even if the syscall is invalid. We return -ENOSYS once we
return from the seccomp filters. Moreover, similar codepaths have
been merged in the process which simplifies somewhat the overall
syscall code.

MIPS: Fix seccomp syscall argument for MIPS64

2015-08-16T13:00:59+00:00

Commit 4c21b8fd8f14 ("MIPS: seccomp: Handle indirect system calls (o32)")
fixed indirect system calls on O32 but it also introduced a bug for MIPS64
where it erroneously modified the v0 (syscall) register with the assumption
that the sycall offset hasn't been taken into consideration. This breaks
seccomp on MIPS64 n64 and n32 ABIs. We fix this by replacing the addition
with a move instruction.

MIPS: N32: Use compat getsockopt syscall

2014-08-01T15:32:23+00:00

The IP_PKTOPTIONS sockopt puts control messages in option_values, these
need to be handled differently in the compat case. This is already done
through the MSG_CMSG_COMPAT flag, we just need to use
compat_sys_getsockopt which sets that flag.
