Subject[PATCH 00/15] selftests/seccomp: Refactor change_syscall()

This refactors the seccomp selftest macros used in change_syscall(),
in an effort to remove special cases for mips, arm, arm64, and xtensa,
which paves the way for powerpc fixes.

I'm not entirely done testing, but all-arch build tests and x86_64
selftests pass. I'll be doing arm, arm64, and i386 selftests shortly,
but I currently don't have an easy way to check xtensa, mips, nor
powerpc. Any help there would be appreciated!

(FWIW, I expect to take these via the seccomp tree.)



Kees Cook (15):
selftests/seccomp: Refactor arch register macros to avoid xtensa
special case
selftests/seccomp: Provide generic syscall setting macro
selftests/seccomp: mips: Define SYSCALL_NUM_SET macro
selftests/seccomp: arm: Define SYSCALL_NUM_SET macro
selftests/seccomp: arm64: Define SYSCALL_NUM_SET macro
selftests/seccomp: mips: Remove O32-specific macro
selftests/seccomp: Remove syscall setting #ifdefs
selftests/seccomp: Convert HAVE_GETREG into ARCH_GETREG/ARCH_SETREG
selftests/seccomp: Convert REGSET calls into ARCH_GETREG/ARCH_SETREG
selftests/seccomp: Avoid redundant register flushes
selftests/seccomp: Remove SYSCALL_NUM_RET_SHARE_REG in favor of
selftests/seccomp: powerpc: Fix seccomp return value testing
selftests/seccomp: powerpc: Set syscall return during ptrace syscall
selftests/clone3: Avoid OS-defined clone_args
selftests/seccomp: Use __NR_mknodat instead of __NR_mknod
