2009-04-14lockdep: warn about lockdep disabling after kernel taint, fixIngo Molnar1-0/+1
Impact: build fix for Sparc and s390 Stephen Rothwell reported that the Sparc build broke: In file included from kernel/panic.c:12: include/linux/debug_locks.h: In function '__debug_locks_off': include/linux/debug_locks.h:15: error: implicit declaration of function 'xchg' due to: 9eeba61: lockdep: warn about lockdep disabling after kernel taint There is some inconsistency between architectures about where exactly xchg() is defined. 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. Use the widest set of headers in debug_locks.h and also include asm/system.h. Reported-by: Stephen Rothwell <sfr@canb.auug.org.au> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: "David S.

2009-04-14ext2: fix data corruption for racing writesJan Kara1-11/+33
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>
2009-04-14shmem: respect MAX_LFS_FILESIZEHugh Dickins1-5/+20
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.

2009-04-14shmem: fix division by zeroYuri Tikhonov1-1/+1
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.

2009-04-14initramfs: fix initramfs to work with hardlinked initRandy Robertson1-1/+2
Change cb6ff208076b5f434db1b8c983429269d719cef5 ("NOMMU: Support XIP on initramfs") seems to have broken booting from initramfs with /sbin/init being a hardlink. It seems like the logic required for XIP on nommu, i.e. ftruncate to reported cpio header file size (body_len) is broken for hardlinks, which have a reported size of 0, and the truncate thus nukes the contents of the file (in my case busybox), making boot impossible and ending with runaway loop modprobe binfmt-0000 - and of course 0000 is not a valid binary format. My fix is to only call ftruncate if size is non-zero which fixes things for me, but I'm not certain whether this will break XIP for those files on nommu systems, although I would guess not.

2009-04-14ptrace: fix exit_ptrace() vs ptrace_traceme() raceOleg Nesterov1-3/+4
Pointed out by Roland. The bug was recently introduced by me in "forget_original_parent: split out the un-ptrace part", commit 39c626ae47c469abdfd30c6e42eff884931380d6. Since that patch we have a window after exit_ptrace() drops tasklist and before forget_original_parent() takes it again. In this window the child can do ptrace(PTRACE_TRACEME) and nobody can untrace this child after that. Change ptrace_traceme() to not attach to the exiting ->real_parent. We don't report the error in this case, we pretend we attach right before ->real_parent calls exit_ptrace() which should untrace us anyway.

2009-04-14spi: spi_write_then_read() bugfixesDavid Brownell1-8/+14
The "simplify spi_write_then_read()" patch included two regressions from the 2.6.27 behaviors: - The data it wrote out during the (full duplex) read side of the transfer was not zeroed. - It fails completely on half duplex hardware, such as Microwire and most "3-wire" SPI variants. So, revert that patch. A revised version should be submitted at some point, which can get the speedup on standard hardware (full duplex) without breaking on less-capable half-duplex stuff.

2009-04-14asm-generic/siginfo.h: update NSIGTRAP definitionAndi Kleen1-1/+1
Impact: (nearly) trivial The patch commit da654b74bda14c45a7d98c731bf3c1a43b6b74e2 Author: Srinivasa Ds <srinivasa@in.ibm.com> Date: Tue Sep 23 15:23:52 2008 +0530 signals: demultiplexing SIGTRAP signal forgot to update the NSIGTRAP define in asm-generic/siginfo.h to the new number of sigtrap subcodes. Nothing in the tree seems to use it, but presumably something in user space might. So update it.
