* fs/affs/file.c: fix direct IO writes beyond EOFFabian Frederick2015-02-171-0/+7
| | | | | | | | | | | | | | | | | | | | | Use the same fallback to normal IO in case of write operations beyond EOF as fat direct IO. This patch fixes fsx file -d -Z -r 4096 -w 4096 Report: 129(129 mod 256): TRUNCATE DOWN from 0x3ff01 to 0xb3f6 130(130 mod 256): WRITE 0x22000 thru 0x2dfff (0xc000 bytes) HOLE Thanks to Jan for helping me on this problem. The ideal solution suggested by Jan Kara would be to use cont_write_begin() but affs direct_IO shouldn't be used a lot anyway...

* eventfd: don't take the spinlock in eventfd_pollChris Mason2015-02-171-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | The spinlock in eventfd_poll is trying to protect the count of events so it can decide if it should return POLLIN, POLLERR, or POLLOUT. But, because of the way we drop the lock after calling poll_wait, and drop it again before returning, we have the same pile of races with the lock as we do with a single read of ctx->count(). This replaces the lock with a read barrier and single read. eventfd_write does a single bump of ctx->count, so this should not add new races with adding events. eventfd_read is similar, it will do a single decrement with the lock held, and so we're making the race with concurrent readers slightly larger. This spinlock is the top CPU user in kernel code during one of our workloads. Removing it gives us a ~2% boost.

* vmcore: fix PT_NOTE n_namesz, n_descsz overflow issueWANG Chao2015-02-171-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When updating PT_NOTE header size (ie. p_memsz), an overflow issue happens with the following bogus note entry: n_namesz = 0xFFFFFFFF n_descsz = 0x0 n_type = 0x0 This kind of note entry should be dropped during updating p_memsz. But because n_namesz is 32bit, after (n_namesz + 3) & (~3), it's overflow to 0x0, the note entry size looks sane and reserved. When userspace (eg. crash utility) is trying to access such bogus note, it could lead to an unexpected behavior (eg. crash utility segment fault because it's reading bogus address). The source of bogus note hasn't been identified yet. At least we could drop the bogus note so user space wouldn't be surprised.

* kexec: add IND_FLAGS macroGeoff Levand2015-02-172-2/+1
| | | | | | | | | | | | | | | | | | | Add a new kexec preprocessor macro IND_FLAGS, which is the bitwise OR of all the possible kexec IND_ kimage_entry indirection flags.

* kexec: add bit definitions for kimage entry flagsGeoff Levand2015-02-171-4/+15
| | | | | | | | | | | | | | | | | | | | | | | | | Define new kexec preprocessor macros IND_*_BIT that define the bit position of the kimage entry flags. Change the existing IND_* flag macros to be defined as bit shifts of the corresponding IND_*_BIT macros. Also wrap all C language code in kexec.h with #if !defined(__ASSEMBLY__) so assembly files can include kexec.h to get the IND_* and IND_*_BIT macros. Some CPU instruction sets have tests for bit position which are convenient in implementing routines that operate on the kimage entry list. The addition of these bit position macros in a common location will avoid duplicate definitions and the chance that changes to the IND_* flags will not be propagated to assembly files.

| | | | | | | | | | | | | | | | | | | | | Simplify the code around one of the conditionals in the kexec_load syscall routine. The original code was confusing with a redundant check on KEXEC_ON_CRASH and comments outside of the conditional block.

| | | | | | | | | | | | | | | | | | | struct kimage has a member destination which is used to store the real destination address of each page when load segment from user space buffer to kernel. But we never retrieve the value stored in kimage->destination, so this member variable in kimage and its assignment operation are redundent code.
