 > Currently seccomp_audit_arch is set to AUDIT_ARCH_MIPS64 or

 > n32 ABI defined in seccomp.h are AUDIT_ARCH_MIPS64N32 and
 > AUDIT_ARCH_MIPSEL64N32, for big and little endian respectively.

 > Because of that an sshd built for MIPS64 n32 rejects connection attempts
 > and the output of strace reveals that the problem is related to seccomp
