Re: [kernel-hardening] [PATCH] add the option of fortified string.h functions

Hi Daniel and ppc people, (ppc people: this does some compile and run time bounds checking on string functions. It's cool - currently it picks up a lot of random things so it will require some more work across the tree, but hopefully it will eventually hit mainline.) I've tested this on ppc with

Re: [PATCH v8 05/10] powerpc/perf: IMC pmu cpumask and cpuhotplug support

Hi all, I've had a look at the API as it was a big thing I didn't like in the earlier version. I am much happier with this one. Some comments: - I'm no longer subscribed to skiboot but I've had a look at the patches on that side: * in patch 9 should opal_imc_counters_init return

[PATCH] powerpc: fix distclean with Makefile.postlink

Makefile.postlink always includes include/config/auto.conf, however this file is not present in a clean kernel tree, causing make to fail: arch/powerpc/Makefile.postlink:10: include/config/auto.conf: No such file or directory make[1]: *** No rule to make target `include/config/auto.conf'. Stop.

[PATCH 2/2] selftests/powerpc: Test TM and VMX register state

Test that the VMX checkpointed register state is maintained when a VMX unavailable exception is taken during a transaction. Thanks to Breno Leitao and Gustavo Bueno Romero for the original test this is based heavily on. Signed-off-by: Michael Neuling

[PATCH 1/2] powerpc/tm: Fix FP and VMX register corruption

In this commit: commit dc3106690b20305c3df06b42456fe386dd632ac9 Author: Cyril Bur powerpc: tm: Always use fp_state and vr_state to store live registers A section of code was removed that copied the current state to checkpointed state. This should not have been removed.

[PATCH] powerpc: Fix asm offsets to point to actual FP and VMX regs

The asm code assumes the FP regs are at the start of fp_state. While this is true now, it may not always be the case and there is nothing enforcing it. This fixes the asm-offsets to point to the actual FP registers inside the fp_state. Similarly for VMX. Signed-off-by: Michael Neuling
