Subject: [PATCH v2 00/10] Kernel Userspace protection for PPC32
Date: Mon, 11 Mar 2019 08:30:26 +0000 (UTC) [thread overview]
Message-ID: <cover.1552292207.git.christophe.leroy@c-s.fr> (raw)
This series intend to implement Kernel Userspace protection for PPC32.
It comes on top of the v5 series for Radix.
The first patch of the series is a fix which is expected to be merged soon.
The second patch is a squash of Russel/Michael series for Radix.
Tested on:
- 8xx
- 83xx (ie book3s32 without hash table)
- QEMU MAC99 (ie book3s32 with hash table)
v2:
- Rebased/adapted the series on top of the v5 series for Radix.
- Reordered the patches so that we first have the ones common to 32 bits, then the 8xx, then book3s32
- Fixed lockup on bad data write (unauthorised write to user) on book3s32 hash.
- Added KUEP for book3s32

powerpc/32: Remove MSR_PR test when returning from syscall
powerpc/32: Prepare for Kernel Userspace Access Protection
powerpc/8xx: Only define APG0 and APG1
powerpc/8xx: Add Kernel Userspace Execution Prevention
powerpc/8xx: Add Kernel Userspace Access Protection
powerpc/32s: Implement Kernel Userspace Execution Prevention.
