Re: [PATCH 0/2] riscv: add audit support

This patchset adds system call audit support on riscv (riscv32 & riscv64). The pachset was prepared on top of v4.19 tag. audit-userspace changes were submitted. See: https://github.com/linux-audit/audit-userspace/pull/73 Tested the following manually: - auditctl (checked several different example rules from internet) - aulast - aulastlog - ausearch - ausyscall - aureport - autrace (compared some syscalls to strace: order and return value/input arguments seem to be correct) - /proc/self/loginuid (required by DNF [package manager]) I looked into audit-testsuite and with some adjustments results are: Failed 4/14 test programs. 19/88 subtests failed. The failing tests were due to missing CONFIG_IP_NF_MANGLE, 'id -Z' not printing categories (don't know why), not having loadable kernel module support enablled and syscall_socketcall not being relevant for new arches. audit-testsuite with adjustments: https://github.com/davidlt/audit-testsuite/tree/riscv64 Depends on: [PATCH 1/2] Move EM_RISCV into elf-em.h http://lists.infradead.org/pipermail/linux-riscv/2018-October/001885.html This should solve DNF issues in Fedora 29/RISCV.
