UAPI Disintegration 2012-10-09
|
|
This is to complete part of the Userspace API (UAPI) disintegration for which
the preparatory patches were pulled recently. After these patches, userspace
headers will be segregated into:
include/uapi/linux/.../foo.h
for the userspace interface stuff, and:
include/linux/.../foo.h
for the strictly kernel internal stuff.

Reverted, as requested by Laurent:
I don't consider it as being ready yet, as Sakari pointed out we need
to investigate whether the right fix shouldn't be at the OMAP3 clocks
level instead.
This reverts commit 947c48086623d9ca2207dd0434bd58458af4ba86.

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes
From Tony Lindgren:
This branch contains regression fixes for omap4/5 ASoC
audio that were caused by the fact that u-boot stopped
muxing non essential pins.
As omap audio and dmaengine development happens on
these platforms, let's make sure they are usable.
Of course this should have been fixed earlier and
not during the -rc cycle.

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes
From Tony Lindgren:
These were agreed to be merged via arm soc tree as Rafael
is on vacation.
From Kevin Hilman <khilman@deeprootsystems.com>:
This series a couple bug fixes and a couple fixes that make this
driver support recently added OMAP-based SoCs.
The 'get_cpu_device' patch is needed due to a change in the OMAP
OMAP PM core code which enforces use of get_cpu_device() instead of
a deprecated OMAP-specific API.
The usage of plat/*.h headers breaks single zImage, so platforms are
cleaning up and/or removing plat/*.h so the driver needs to be fixed
accordingly.
This series is based on the merge of Rafael's pm-for-3.7-rc1 tag into
Linus' master branch: commit 16642a2e7be23bbda013fc32d8f6c68982eab603.

This is the ext3 version of the same patch applied to Ext4, where such goal is
to audit the usage of ext3_bread() due a possible misinterpretion of its return
value.
Focused on directory blocks, a NULL value returned from ext3_bread() means a
hole, which cannot exist into a directory inode. It can pass undetected after a
fix in an uninitialized error variable.
The (now) initialized variable into ext3_getblk() may lead to a zero'ed return
value of ext3_bread() to its callers, which can make the caller do not detect
the hole in the directory inode.
This patch creates a new wrapper function ext3_dir_bread() which checks for
holes properly, reports error, and returns EIO in that case.

This is a backport of ext4 commit 90b0a9732 which fixes a possible
non-initialized variable on htree_dirblock_to_tree().
Ext3 has the same non initialized variable, but, in any case it will be
initialized by ext3_get_blocks_handle(), which will avoid the bug to be
triggered, but, the non-initialized variable by htree_dirblock_to_tree() is
still a bug.

In case of error, the function get_inode() returns ERR_PTR().
But the users hppfs_lookup() and hppfs_fill_super() use NULL
test for check the return value, not IS_ERR(), so we'd better
change the return value of get_inode() to NULL instead of
ERR_PTR().

The definition of ARCH_SLAB_MINALIGN is architecture dependent
and can be either of type size_t or int. Comparing that value
with ARCH_KMALLOC_MINALIGN can cause harmless warnings on
platforms where they are different. Since both are always
small positive integer numbers, using the size_t type to compare
them is safe and gets rid of the warning.

Adding two (or more) timers with large values for "expires" (they have
to reside within tv5 in the same list) leads to endless looping
between cascade() and internal_add_timer() in case CONFIG_BASE_SMALL
is one and jiffies are crossing the value 1 << 18. The bug was
introduced between 2.6.11 and 2.6.12 (and survived for quite some
time).
This patch ensures that when cascade() is called timers within tv5 are
not added endlessly to their own list again, instead they are added to
the next lower tv level tv4 (as expected).

The Linaro cross toolchain and probably others nowadays default to
building in THUMB2 mode. When building a kernel for a CPU that does
not support THUMB2, the compiler complains about incorrect flags.
We can work around this by setting -marm for all non-T2 builds.
-marm was passed unconditionally for C files previously, but nothing was
passed to the gcc frontend when processing .S files, resulting in a
warning. The assembler never defaults to ARM unless -Wa,-mthumb is
supplied explicitly, so the files were still assembled correctly.
This patch makes sure that -marm is passed for .S files too, and also
avoids the redundant gcc -marm -mthumb in Thumb kernels.

This is the revised patch for fixing rds-ping spinlock recursion
according to Venkat's suggestions.
RDS ping/pong over TCP feature has been broken for years(2.6.39 to
3.6.0) since we have to set TCP cork and call kernel_sendmsg() between
ping/pong which both need to lock "struct sock *sk". However, this
lock has already been hold before rds_tcp_data_ready() callback is
triggerred. As a result, we always facing spinlock resursion which
would resulting in system panic.
Given that RDS ping is only used to test the connectivity and not for
serious performance measurements, we can queue the pong transmit to
rds_wq as a delayed response.

Fengguang reported a kernel build failure as following:

pch_gbe_main.c:(.text+0x5103b3): undefined reference to `pch_ch_control_write'
...
It's a regression by commit da1586461. The root cause is that
the CONFIG_PPS is not set there, consequently CONFIG_PTP_1588_CLOCK
can not be set anyway, which finally causes ptp_pch and pch_gbe_main
build failures.
As David prefers to use *select* to fix such module co-dependency issues,
this patch explicitly selects all the possible dependencies of PCH_PTP.

Pulled mainline in order to get the UAPI infrastructure already
merged before I pull in David Howells's UAPI trees for networking.

Fix two bugs of the /dev/fw* character device concerning the
FW_CDEV_IOC_GET_INFO ioctl with nonzero fw_cdev_get_info.bus_reset.
(Practically all /dev/fw* clients issue this ioctl right after opening
the device.)
Both bugs are caused by sizeof(struct fw_cdev_event_bus_reset) being 36
without natural alignment and 40 with natural alignment.
1) Memory corruption, affecting i386 userland on amd64 kernel:
Userland reserves a 36 bytes large buffer, kernel writes 40 bytes.
This has been first found and reported against libraw1394 if
compiled with gcc 4.7 which happens to order libraw1394's stack such
that the bug became visible as data corruption.
2) Information leak, affecting all kernel architectures except i386:
4 bytes of random kernel stack data were leaked to userspace.
Hence limit the respective copy_to_user() to the 32-bit aligned size of
struct fw_cdev_event_bus_reset.

Three more warnings fixes from Arnd Bergmann:
* fixes2:
ARM: integrator: use __iomem pointers for MMIO, part 2
ARM: assabet: fix bogus warning in get_assabet_scr (again)
ARM: shmobile: mark shmobile_init_late as __init
|
|
Due to some interesting merges in the integrator code, not
all users of mmio pointers were converted before, this
fixes all warnings that got introduced as a consequence.
