Pull gcc-plugins fix from Kees Cook:
 "Fixes a typo in sancov plugin, exposed in earlier compiler versions"

* tag 'gcc-plugins-v4.11-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux:
  gcc-plugins: fix sancov_plugin for gcc-5

gcc-plugins: fix sancov_plugin for gcc-5

2017-02-27T22:10:10+00:00

The name of the local variable was inadvertantly changed from
sancov_plugin_pass_info to sancov_pass_info:

scripts/gcc-plugins/sancov_plugin.c: In function ‘int plugin_init(plugin_name_args*, plugin_gcc_version*)’:
scripts/gcc-plugins/sancov_plugin.c:136:67: error: ‘sancov_plugin_pass_info’ was not declared in this scope

This changes the conditional reference to this variable as well.

gcc-plugins: Add structleak for more stack initialization

2017-01-18T20:02:35+00:00

This plugin detects any structures that contain __user attributes and
makes sure it is being fully initialized so that a specific class of
information exposure is eliminated. (This plugin was originally designed
to block the exposure of siginfo in CVE-2013-2141.)

Ported from grsecurity/PaX. This version adds a verbose option to the
plugin and the Kconfig.

gcc-plugins: consolidate on PASS_INFO macro

2017-01-13T22:20:03+00:00

Now that PASS_INFO() exists, use it in the other existing gcc plugins,
instead of always open coding the same thing.

Based on updates to the grsecurity/PaX gcc plugins.

gcc-plugins: add PASS_INFO and build_const_char_string()

2017-01-11T00:50:57+00:00

This updates the GCC plugins gcc-common.h from PaX Team to include
more helpers and header files, specifically adds the PASS_INFO()
macro to make plugin declarations nicer and a helper for proper
const string building.

by Kugan and Arnd. Build tested with gcc 5.4 and 7 snapshot.

latent_entropy: fix ARM build error on earlier gcc

2017-01-03T20:08:59+00:00

This fixes build errors seen on gcc-4.9.3 or gcc-5.3.1 for an ARM:

arm-soc/init/initramfs.c: In function 'error':
arm-soc/init/initramfs.c:50:1: error: unrecognizable insn:

latent_entropy: Fix wrong gcc code generation with 64 bit variables

2016-10-31T18:30:41+00:00

The stack frame size could grow too large when the plugin used long long
on 32-bit architectures when the given function had too many basic blocks.

The gcc warning was:

drivers/pci/hotplug/ibmphp_ebda.c: In function 'ibmphp_access_ebda':
drivers/pci/hotplug/ibmphp_ebda.c:409:1: warning: the frame size of 1108 bytes is larger than 1024 bytes [-Wframe-larger-than=]

This switches latent_entropy from u64 to unsigned long.

Thanks to PaX Team and Emese Revfy for the patch.
