Hi, This patch improves the existing seccomp-bpf support for MIPS. It fixes a bug when copying system call arguments for the filter checks and it also moves away from strict filtering to actually use the filter supplied by the userspace process. This patchset has been tested with libseccomp (MIPS support not upstream yet) on mips, mipsel and mips64 and with Chromium test suite (MIPS support not upstream yet) on mipsel. This patchset is based on the upstream-sfr/mips-for-linux-next tree.
