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.

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:

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. Signed-off-by:

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. Signed-off-by:

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:

David Brownell authored
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.)

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:

This reverts commit 7c9e69fa, 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.

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:
