2009-04-15GFS2: Fix symlink creation raceSteven Whitehouse
In certain cases symlinks can appear to have zero size if a lookup on the inode occurs within a certain (very short) time after the symlink has been created. The symlink is correctly created on disk but appears to have zero size when stat()ed. This patch closes the race and prevents incorrect sizes appearing.

2009-04-14x86 microcode: revert some work_on_cpuHugh Dickins
Revert part of af5c820a3169e81af869c113e18ec7588836cd50 ("x86: cpumask: use work_on_cpu in arch/x86/kernel/microcode_core.c") That change is causing only one Intel CPU's microcode to be updated e.g. microcode: CPU3 updated from revision 0x9 to 0x17, date = 2005-04-22 where before it announced that also for CPU0 and CPU1 and CPU2. We cannot use work_on_cpu() in the CONFIG_MICROCODE_OLD_INTERFACE code, because Intel's request_microcode_user() involves a copy_from_user() from /sbin/microcode_ctl, which therefore needs to be on that CPU at the time.

2009-04-14Fix lpfc_parse_bg_err()'s use of do_div()David Howells
Fix lpfc_parse_bg_err()'s use of do_div(). It should be passing a 64-bit variable as the first parameter. However, since it's only using a 32-bit variable, it doesn't need to use do_div() at all, but can instead use the division operator.

The traditional place is in system.h but the more logical point for it is in atomic.h - where most architectures (especially new ones) have it defined. These architecture also still offer it via system.h. Some, such as Sparc or s390 only have it in asm/system.h and not available via asm/atomic.h at all.

2009-04-13ext2: fix data corruption for racing writesJan Kara
If two writers allocating blocks to file race with each other (e.g. because writepages races with ordinary write or two writepages race with each other), ext2_getblock() can be called on the same inode in parallel. Before we are going to allocate new blocks, we have to recheck the block chain we have obtained so far without holding truncate_mutex. Otherwise we could overwrite the indirect block pointer set by the other writer leading to data loss. The below test program by Ying is able to reproduce the data loss with ext2 on in BRD in a few minutes if the machine is under memory pressure: long kMemSize = 50 << 20; int kPageSize = 4096; int main(int argc, char **argv) { int status; int count = 0; int i; char *fname = "/mnt/test.mmap"; char *mem; unlink(fname); int fd = open(fname, O_CREAT | O_EXCL | O_RDWR, 0600); status = ftruncate(fd, kMemSize); mem = mmap(0, kMemSize, PROT_READ | PROT_WRITE, MAP_SHARED, fd, 0); // Fill the memory with 1s. memset(mem, 1, kMemSize); sleep(2); for (i = 0; i < kMemSize; i++) { int byte_good = mem[i] != 0; if (!byte_good && ((i % kPageSize) == 0)) { //printf("%d ", i / kPageSize); count++; } } munmap(mem, kMemSize); close(fd); unlink(fname); if (count > 0) { printf("Running %d bad page\n", count); return 1; } return 0; } Cc: Ying Han <yinghan@google.com> Cc: Nick Piggin <nickpiggin@yahoo.com.au> Signed-off-by: Jan Kara <jack@suse.cz> Cc: Mingming Cao <cmm@us.ibm.com> Cc: <linux-ext4@vger.kernel.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2009-04-13shmem: respect MAX_LFS_FILESIZEHugh Dickins
SHMEM_MAX_BYTES was derived from the maximum size of its triple-indirect swap vector, forgetting to take the MAX_LFS_FILESIZE limit into account. Never mind 256kB pages, even 8kB pages on 32-bit kernels allowed files to grow slightly bigger than that supposed maximum. Fix this by using the min of both (at build time not run time). And it happens that this calculation is good as far as 8MB pages on 32-bit or 16MB pages on 64-bit: though SHMSWP_MAX_INDEX gets truncated before that, it's truncated to such large numbers that we don't need to care.

2009-04-13shmem: fix division by zeroYuri Tikhonov
Fix a division by zero which we have in shmem_truncate_range() and shmem_unuse_inode() when using big PAGE_SIZE values (e.g. 256kB on ppc44x). With 256kB PAGE_SIZE, the ENTRIES_PER_PAGEPAGE constant becomes too large (0x1.0000.0000) on a 32-bit kernel, so this patch just changes its type from 'unsigned long' to 'unsigned long long'. Hugh: reverted its unsigned long longs in shmem_truncate_range() and shmem_getpage(): the pagecache index cannot be more than an unsigned long, so the divisions by zero occurred in unreached code. It's a pity we need any ULL arithmetic here, but I found no pretty way to avoid it.
