Subject: [PATCH v5 0/8] set_memory() routines and STRICT_MODULE_RWX
Date: Wed, 26 Feb 2020 17:35:43 +1100 [thread overview]
Message-ID: <20200226063551.65363-1-ruscur@russell.cc> (raw)
Repost from v4 because I somehow missed half of the final patch.
Picking up from Christophe's last series, including the following changes:
- [6/8] Cast "data" to unsigned long instead of int to fix build
- [8/8] New, to fix an issue reported by Jordan Niethe
Christophe's last series is here:
https://patchwork.ozlabs.org/project/linuxppc-dev/list/?series=156428
Christophe Leroy (4):
powerpc/mm: Implement set_memory() routines
powerpc/kprobes: Mark newly allocated probes as RO
powerpc/mm: implement set_memory_attr()
powerpc/32: use set_memory_attr()
Russell Currey (4):
powerpc/mm/ptdump: debugfs handler for W+X checks at runtime
powerpc: Set ARCH_HAS_STRICT_MODULE_RWX
powerpc/configs: Enable STRICT_MODULE_RWX in skiroot_defconfig
powerpc/mm: Disable set_memory() routines when strict RWX isn't
enabled
