From 615829a03dc729e78372d40d95ba40e2ad51783b Mon Sep 17 00:00:00 2001
From: Paolo Bonzini <pbonzini@redhat.com>
Date: Thu, 31 Mar 2016 09:38:51 +0200
Subject: compiler-gcc: disable -ftracer for __noclone functions
commit 95272c29378ee7dc15f43fa2758cb28a5913a06d upstream.
-ftracer can duplicate asm blocks causing compilation to fail in
noclone functions. For example, KVM declares a global variable
in an asm like
asm("2: ... \n
.pushsection data \n
.global vmx_return \n
vmx_return: .long 2b");
and -ftracer causes a double declaration.

From: Joe Perches <joe@perches.com>
Date: Thu, 25 Jun 2015 15:01:02 -0700
Subject: compiler-gcc: integrate the various compiler-gcc[345].h files
commit f320793e52aee78f0fbb8bcaf10e6614d2e67bfc upstream.
[ Upstream commit cb984d101b30eb7478d32df56a0023e4603cba7f ]
As gcc major version numbers are going to advance rather rapidly in the
future, there's no real value in separate files for each compiler
version.
Deduplicate some of the macros #defined in each file too.
Neaten comments using normal kernel commenting style.

From 23567fd052a9abb6d67fe8e7a9ccdd9800a540f2 Mon Sep 17 00:00:00 2001
From: Yevgeny Pats <yevgeny@perception-point.io>

Subject: KEYS: Fix keyring ref leak in join_session_keyring()
This fixes CVE-2016-0728.
If a thread is asked to join as a session keyring the keyring that's already
set as its session, we leak a keyring reference.
This can be tested with the following program:
#include <stddef.h>
#include <stdio.h>
#include <sys/types.h>
#include <keyutils.h>
int main(int argc, const char *argv[])
{
int i = 0;
key_serial_t serial;
serial = keyctl(KEYCTL_JOIN_SESSION_KEYRING,
"leaked-keyring");
if (serial < 0) {
perror("keyctl");
return -1;
}
if (keyctl(KEYCTL_SETPERM, serial,
KEY_POS_ALL | KEY_USR_ALL) < 0) {
perror("keyctl");
return -1;
}
for (i = 0; i < 100; i++) {
serial = keyctl(KEYCTL_JOIN_SESSION_KEYRING,
"leaked-keyring");
if (serial < 0) {
perror("keyctl");
return -1;
}
}
return 0;
}
If, after the program has run, there something like the following line in
/proc/keys:
3f3d898f I--Q--- 100 perm 3f3f0000 0 0 keyring leaked-keyring: empty
with a usage count of 100 * the number of times the program has been run,
then the kernel is malfunctioning. If leaked-keyring has zero usages or
has been garbage collected, then the problem is fixed.
