* NFS: Fix a spinlock recursion inside nfs_update_inode()Trond Myklebust2005-11-25
| | | | | | | | | | | | | | | | | In cases where the server has gone insane, nfs_update_inode() may end up calling nfs_invalidate_inode(), which again calls stuff that takes the inode->i_lock that we're already holding. In addition, given the sort of things we have in NFS these days that need to be cleaned up on inode release, I'm not sure we should ever be calling make_bad_inode(). Fix up spinlock recursion, and limit nfs_invalidate_inode() to clearing the caches, and marking the inode as being stale. Thanks to Steve Dickson <SteveD@redhat.com> for spotting this.

* [PATCH] fix do_wait() vs exec() raceOleg Nesterov2005-11-23
| | | | | | | | | | | | | | | | | | When non-leader thread does exec, de_thread adds old leader to the init's ->children list in EXIT_ZOMBIE state and drops tasklist_lock. This means that release_task(leader) in de_thread() is racy vs do_wait() from init task. I think de_thread() should set old leader's state to EXIT_DEAD instead.

* [PATCH] Fix hugetlbfs_statfs() reporting of block limitsDavid Gibson2005-11-22
| | | | | | | | | | | | | | | | | Currently, if a hugetlbfs is mounted without limits (the default), statfs() will return -1 for max/free/used blocks. This does not appear to be in line with normal convention: simple_statfs() and shmem_statfs() both return 0 in similar cases. Worse, it confuses the translation logic in put_compat_statfs(), causing it to return -EOVERFLOW on such a mount. This patch alters hugetlbfs_statfs() to return 0 for max/free/used blocks on a mount without limits. Note that we need the test in the patch below, rather than just using 0 in the sbinfo structure, because the -1 marked in the free blocks field is used internally to tell the Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] Fix error handling with put_compat_statfs()David Gibson2005-11-22
| | | | | | | | | | | | | | | | | | | | | | In fs/compat.c, whenever put_compat_statfs() returns an error, the containing syscall returns -EFAULT. This is presumably by analogy with the non-compat case, where any non-zero code from copy_to_user() should be translated into an EFAULT. However, put_compat_statfs() is also return -EOVERFLOW. The same applies for put_compat_statfs64(). This bug can be observed with a statfs() on a hugetlbfs directory. hugetlbfs, when mounted without limits reports available, free and total blocks as -1 (itself a bug, another patch coming). statfs() will mysteriously return EFAULT although it's parameters are perfectly valid addresses. This patch causes the compat versions of statfs() and statfs64() to correctly propogate the return values from put_compat_statfs() and put_compat_statfs64().

I do not think that this problem is exploitable, but any data corruption may lead to security problems. Following code demonstrates the problem #include <stdint.h> #include <stdio.h> #include <sys/time.h> #include <sys/socket.h> #include <net/if.h> #include <sys/ioctl.h> char buf[256]; main() { int s = socket(AF_INET, SOCK_DGRAM, 0); struct ifconf req; int i; req.ifc_buf = buf; req.ifc_len = 41; printf("Result %d\n", ioctl(s, SIOCGIFCONF, &req)); printf("Len %d\n", req.ifc_len); for (i = 41; i < 256; i++) if (buf[i] != 0) printf("Byte %d is corrupted\n", i); } Steps to reproduce: Compile the code above into 32-bit elf and run it. You'll get Result 0 Len 32 Byte 48 is corrupted Byte 52 is corrupted Byte 53 is corrupted Byte 54 is corrupted Byte 55 is corrupted Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: David S.

They call ->readv/->writev which we now always implemente. - add the filemap_fdatawrite calls to writev/aio_write which were missing previously compared to plain write. no idea what the point behind them is, but let's be consistent at least..

| * [PATCH] aio: remove kioctx from mm_structZach Brown2005-11-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sync iocbs have a life cycle that don't need a kioctx. Their retrying, if any, is done in the context of their owner who has allocated them on the stack. The sole user of a sync iocb's ctx reference was aio_complete() checking for an elevated iocb ref count that could never happen. No path which grabs an iocb ref has access to sync iocbs. If we were to implement sync iocb cancelation it would be done by the owner of the iocb using its on-stack reference. Removing this chunk from aio_complete allows us to remove the entire kioctx instance from mm_struct, reducing its size by a third. On a i386 testing box the slab size went from 768 to 504 bytes and from 5 to 8 per page.

When freeing the lease, the code in locks_delete_lock() will correctly clean up the fasync queue, but when we return to fcntl_setlease(), the freed fasync entry will be reinstated.
