This changes the stack protector config option into a choice of
"None", "Regular", and "Strong":
CONFIG_CC_STACKPROTECTOR_NONE
CONFIG_CC_STACKPROTECTOR_REGULAR
CONFIG_CC_STACKPROTECTOR_STRONG
"Regular" means the old CONFIG_CC_STACKPROTECTOR=y option.
"Strong" is a new mode introduced by this patch. With "Strong" the
kernel is built with -fstack-protector-strong (available in
gcc 4.9 and later). This option increases the coverage of the stack
protector without the heavy performance hit of -fstack-protector-all.
For reference, the stack protector options available in gcc are:
-fstack-protector-all:
Adds the stack-canary saving prefix and stack-canary checking
suffix to _all_ function entry and exit. Results in substantial
use of stack space for saving the canary for deep stack users
(e.g. historically xfs), and measurable (though shockingly still
low) performance hit due to all the saving/checking. Really not
suitable for sane systems, and was entirely removed as an option
from the kernel many years ago.
-fstack-protector:
Adds the canary save/check to functions that define an 8
(--param=ssp-buffer-size=N, N=8 by default) or more byte local
char array. Traditionally, stack overflows happened with
string-based manipulations, so this was a way to find those
functions. Very few total functions actually get the canary; no
measurable performance or size overhead.
-fstack-protector-strong
Adds the canary for a wider set of functions, since it's not
just those with strings that have ultimately been vulnerable to
stack-busting. With this superset, more functions end up with a
canary, but it still remains small compared to all functions
with only a small change in performance. Based on the original
design document, a function gets the canary when it contains any
of:
- local variable's address used as part of the right hand side
of an assignment or function argument
- local variable is an array (or union containing an array),
regardless of array type or length
- uses register local variables
https://docs.google.com/a/google.com/document/d/1xXBH6rRZue4f296vGt9YQcuLVQHeE516stHwt8M9xyU
Find below a comparison of "size" and "objdump" output when built with
gcc-4.9 in three configurations:
- defconfig
11430641 kernel text size
36110 function bodies
- defconfig + CONFIG_CC_STACKPROTECTOR_REGULAR
11468490 kernel text size (+0.33%)
1015 of 36110 functions are stack-protected (2.81%)
- defconfig + CONFIG_CC_STACKPROTECTOR_STRONG via this patch
11692790 kernel text size (+2.24%)
7401 of 36110 functions are stack-protected (20.5%)
With -strong, ARM's compressed boot code now triggers stack
protection, so a static guard was added. Since this is only used
during decompression and was never used before, the exposure
here is very small. Once it switches to the full kernel, the
stack guard is back to normal.
Chrome OS has been using -fstack-protector-strong for its kernel
builds for the last 8 months with no problems.

This patch removes a bug in enlarge_buffer() that can make a
read or write fail under special conditions.
After changing TRY_DIRECT_IO to 0 and ST_MAX_SG to 32 in
st_options.h, a program that writes a first block of 128k and
than a second bigger block (e.g. 256k) fails. The second write
returns errno EOVERFLOW, as enlarge_buffer() checks the sg list
and detects that it already is full.
As enlarge_buffer uses different page allocation orders
depending on the size of the buffer needed, the check does not
make sense.

Intel Wired LAN Driver Updates
This series contains updates to net, ixgbe and e1000e.
David provides compiler fixes for e1000e.
Don provides a fix for ixgbe to resolve a compile warning.
John provides a fix to net where it is useful to be able to walk all
upper devices when bringing a device online where the RTNL lock is held.
In this case, it is safe to walk the all_adj_list because the RTNL lock is
used to protect the write side as well. This patch adds a check to see
if the RTNL lock is held before throwing a warning in
netdev_all_upper_get_next_dev_rcu().

This version corrects the whitespace issue.
orion_mdio_wait_ready uses wait_event_timeout to wait for the
SMI interrupt to fire. wait_event_timeout waits for between
"timeout - 1" and "timeout" jiffies. In this case a 1ms timeout
when HZ is 1000 results in a wait of 0 to 1 jiffies, causing
premature timeouts.
This fix ensures a minimum timeout of 2 jiffies, ensuring
wait_event_timeout will always wait at least 1 jiffie.

Prior to subitting this, Colin reworked the compat_ioctl support
for the ion_test driver, moving the structure to be the same size
on both 32 and 64 bit architectures.
Two small things were left out. The compat_ioctl ptr assignment,
and the fact that despite having uniform sized types in the
structure, the structure pads out to different sizes on different
arches.
This patch resolves this issue by adding a padding entry after
the write flag, and adding the compat_ioctl ptr.
Changes in v2:
- Add a padding int rather then making write a u64

ip6_rt_copy only sets dst.from if ort has flag RTF_ADDRCONF and RTF_DEFAULT.
but the prefix routes which did get installed by hand locally can have an
expiration, and no any flag combination which can ensure a potential from
does never expire, so we should always set the new created dst's from.
This also fixes the new created dst is always expired since the ort, which
is created by RA, maybe has RTF_EXPIRES and RTF_ADDRCONF, but no RTF_DEFAULT.

The PCI MSI sysfs code is a mess with kobjects for things that don't really
need to be kobjects. This patch creates attributes dynamically for the MSI
interrupts instead of using kobjects.
Note, this removes a directory from sysfs. Old MSI kobjects:
pci_device
└── msi_irqs
└── 40
└── mode
New MSI attributes:
pci_device
└── msi_irqs
└── 40
As there was only one file "mode" with the kobject model, the interrupt
number is now a file that returns the "mode" of the interrupt (msi vs.
msix).

The addr_location struct should fully qualify an address, and to do that
it should have in it the machine where the thread was found.
Thus all functions that receive an addr_location now don't need to also
receive a 'machine', those functions just need to access al->machine
instead, just like it does with the other parts of an address location:
al->thread, al->map, etc.

Commit 7ea6c6c1 ("Move cper.c from drivers/acpi/apei to
drivers/firmware/efi") results in CONFIG_EFI being enabled even
when the user doesn't want this. Since ACPI APEI used to build
fine without UEFI (and as far as I know also has no functional
depency on it), at least in that case using a reverse dependency
is wrong (and a straight one isn't needed).
Whether the same is true for ACPI_EXTLOG I don't know - if there
is a functional dependency, it should depend on EFI rather than
selecting it. It certainly has (currently) no build dependency.
Adjust Kconfig and build logic so that the bad dependency gets
avoided.

The yam_ioctl() code fails to initialise the cmd field
of the struct yamdrv_ioctl_cfg. Add an explicit memset(0)
before filling the structure to avoid the 4-byte info leak.

The 'evsel' parameter is not used, ditch it, reducing the function
signature.

The local variable 'bi' comes from userspace. If userspace passed a
large number to 'bi.data.calibrate', there would be an integer overflow
in the following line:
s->hdlctx.calibrate = bi.data.calibrate * s->par.bitrate / 16;
