Forbid user from changing file flags on quota files. User has no bussiness
in playing with these flags when quota is on. Furthermore there is a
remote possibility of deadlock due to a lock inversion between quota file's
i_mutex and transaction's start (i_mutex for quota file is locked only when
trasaction is started in quota operations) in ext3 and ext4.Signed-off-by: Jan Kara

pud_clear wasn't setting the _PAGE_NEWPAGE bit, fooling tlb_flush into
thinking that this area of the address space was up-to-date and not unmapping
whatever was covered by the pud.This manifested itself as ldconfig on x86_64 complaining about the first
library it looked at not being a valid ELF file. A config file is mapped at
0x4000000, as the only thing mapped under its pud, and unmapped. The
unmapping caused a pud_clear, which, due to this bug, didn't actually unmap
the config file data on the host. The first library is then mapped at the
same location, but is not actually mapped on the host because accesses to it
cause no page faults. As a result, ldconfig sees the old config file data.[akpm@linux-foundation.org: coding-style cleanups]

Stupid bug - we need to compare the return value of recvmsg to the value of
iov_len, not its size. This caused port_helper processes not to be killed on
shutdown on x86_64 because the pids weren't being passed out properly.Signed-off-by: Jeff Dike

Instruction pointer returned by profile_pc() can be a random value. This
break the assumption than we can safely set struct op_sample.eip field to a
magic value to signal to the per-cpu buffer reader side special event like
task switch ending up in a segfault in get_task_mm() when profile_pc()
return ~0UL. Fixed by sanitizing the sampled eip and reject/log invalid
eip.Problem reported by Sami Farin, patch tested by him.

mac80211 has a reference to __bitmap_empty() via bitmap_empty(). In
lib/bitmap.c this is flagged with an EXPORT_SYMBOL(), but this is
ultimately ineffective due to bitmap.o being linked in lib-y, resulting in:ERROR: "__bitmap_empty" [net/mac80211/mac80211.ko] undefined!
Moving bitmap.o to obj-y fixes this up.

When PCMCIA_DEBUG is set, cm40x0_cs.c and cm4000_cs.c don't build because the
definition of reader_to_dev uses a non-existent handle field of the struct
pcmcia_device in the call to handle_to_dev. As handle_to_dev works on struct
pcmcia_device, the fix is quite trivial.Signed-off-by: Pascal Terjan

Export the NVRAM on DS1307 and DS1338 chips, like several of the

Signed-off-by: Linus Torvalds -
Several of the RTC drivers are exporting binary "nvram" files in sysfs. Such
NVRAM (or on many systems, EEPROM) data is often initialized during system
manufacture to hold data about identity (serial numbers, Ethernet addresses,
etc), configuration, calibration, and so forth.This patch improves integrity and security of those files:
- Correctly initializes the size in one of the two cases where
that was not yet being done.- Improves system security/integrity by making this state not
be world-writable by default.Letting arbitrary userspace code mangle such state by default is at least Not
A Good Thing; and it could sometimes be worse, depending on the particular
data that might be corrupted. (I disregard the paranoiac "don't let anyone
read it either" approach. Anyone storing passwords in such memory doesn't
really care about security.)Signed-off-by: David Brownell

The RTC "hctosys" mechanism expects that RTC clock will use UTC, not local
time (e.g. PST). Say so in Kconfig and in the kernel message.(Strictly speaking, the RTC clock should be tracking the POSIX epoch. That's
not worth going into here. Goofing timezones means clocks are wrong by many
hours; the POSIX-v-UTC differences just cost seconds.)Signed-off-by: David Brownell

This reverts commit 7c9e69faa28027913ee059c285a5ea8382e24b5d, fixing up
conflicts in fs/ext4/balloc.c manually.The cost of doing the bitmap validation on each lookup - even when the
bitmap is cached - is absolutely prohibitive. We could, and probably
should, do it only when adding the bitmap to the buffer cache. However,
right now we are better off just reverting it.Peter Zijlstra measured the cost of this extra validation as a 85%
decrease in cached iozone, and while I had a patch that took it down to
just 17% by not being _quite_ so stupid in the validation, it was still
a big slowdown that could have been avoided by just doing it right.Cc: Peter Zijlstra

If CONFIG_NET_NS is not set, the only namespace is possible.
This patch removes list of pernet_operations and cleanups code a bit.
This list is not needed if there are no namespaces. We should just call
->init method.Additionally, the ->exit will be called on module unloading only. This
case is safe - the code is not discarded. For the in/kernel code, ->exit
should never be called.Signed-off-by: Denis V. Lunev
