[PATCH 0/2] riscv: add audit support

From: David Abdurachmanov
Date: Mon Oct 29 2018 - 06:49:19 EST


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:

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.
