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.

MIPS: Add numa api support

Enable sys_mbind()/sys_get_mempolicy()/sys_set_mempolicy() for O32, N32, and N64 ABIs. By the way, O32/N32 should use the compat version of sys_migrate_pages()/sys_move_pages(), so fix that.
