+Subject: [PATCH] configure.ac: properly set seccomp_audit_arch for MIPS64
+
+Currently seccomp_audit_arch is set to AUDIT_ARCH_MIPS64 or
+AUDIT_ARCH_MIPSEL64 (depending on the endinness) when openssh is built
+for MIPS64. However, that's only valid for n64 ABI. The right macros for
+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
+audit:
+
+[pid   194] prctl(PR_SET_SECCOMP, SECCOMP_MODE_FILTER, {len=57,
+filter=0x555d5da0}) = 0
+[pid   194] write(7, "\0\0\0]\0\0\0\5\0\0\0Ulist_hostkey_types: "..., 97) = ?
+[pid   193] <... poll resumed> )        = 2 ([{fd=5, revents=POLLIN|POLLHUP},
+{fd=6, revents=POLLHUP}])
+[pid   194] +++ killed by SIGSYS +++
+
+This patch fixes that problem by setting the right value to
+seccomp_audit_arch taking into account the MIPS64 ABI.
