openssh: fix sshd for MIPS64 n32
This patch backports two patches that have been sent upstream as a pull request in order to fix sshd for MIPS64 n32. The first patch adds support for detecting the MIPS ABI during the configure phase. The second patch sets the right value to seccomp_audit_arch taking into account the MIPS64 ABI. 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 +++ Pull request: https://github.com/openssh/openssh-portable/pull/71 Signed-off-by: Vicente Olivert Riera <Vincent.Riera@imgtec.com> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
