* [PATCH] fuse: fix Oops in lookupMiklos Szeredi2006-11-251-14/+38
| | | | | | | | | | | | | | | | | | Fix bug in certain error paths of lookup routines. The request object was reused for sending FORGET, which is illegal. This bug could cause an Oops in 2.6.18. In earlier versions it might silently corrupt memory, but this is very unlikely. These error paths are never triggered by libfuse, so this wasn't noticed even with the 2.6.18 kernel, only with a filesystem using the raw kernel interface. Thanks to Russ Cox for the bug report and test filesystem.

* [PATCH] hugetlb: prepare_hugepage_range check offset tooHugh Dickins2006-11-141-13/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (David:) If hugetlbfs_file_mmap() returns a failure to do_mmap_pgoff() - for example, because the given file offset is not hugepage aligned - then do_mmap_pgoff will go to the unmap_and_free_vma backout path. But at this stage the vma hasn't been marked as hugepage, and the backout path will call unmap_region() on it. That will eventually call down to the non-hugepage version of unmap_page_range(). On ppc64, at least, that will cause serious problems if there are any existing hugepage pagetable entries in the vicinity - for example if there are any other hugepage mappings under the same PUD. unmap_page_range() will trigger a bad_pud() on the hugepage pud entries. I suspect this will also cause bad problems on ia64, though I don't have a machine to test it on. (Hugh:) prepare_hugepage_range() should check file offset alignment when it checks virtual address and length, to stop MAP_FIXED with a bad huge offset from unmapping before it fails further down. PowerPC should apply the same prepare_hugepage_range alignment checks as ia64 and all the others do. Then none of the alignment checks in hugetlbfs_file_mmap are required (nor is the check for too small a mapping); but even so, move up setting of VM_HUGETLB and add a comment to warn of what David Gibson discovered - if hugetlbfs_file_mmap fails before setting it, do_mmap_pgoff's unmap_region when unwinding from error will go the non-huge way, which may cause bad behaviour on architectures (powerpc and ia64) which segregate their huge mappings into a separate region of the address space.

| | | | | | | | | | | | | | Resolve the panic on failed mount of an autofs filesystem originally reported by Mao Bibo. It addresses two issues that happen after the mount fail.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The previous fixes for the use after free in xfs_iunpin left a nasty log deadlock when xfslogd unpinned the inode and dropped the last reference to the inode. the ->clear_inode() method can issue transactions, and if the log was full, the transaction could push on the log and get stuck trying to push the inode it was currently unpinning. To fix this, we provide xfs_iunpin a guarantee that it will always have a valid xfs_inode <-> linux inode link or a particular flag will be set on the inode. We then use log forces during lookup to ensure transactions are completed before we recycle the inode. This ensures that xfs_iunpin will never use the linux inode after it is being freed, and any lookup on an inode on the reclaim list will wait until it is safe to attach a new linux inode to the xfs inode.

| * [DLM] fix oops in kref_put when removing a lockspacePatrick Caulfield2006-11-061-0/+5
| | | | | | | | | | | | | | | | | | | | Now that the lockspace struct is freed when the last sysfs object is released this patch prevents use of that lockspace by sysfs. We attempt to re-get the lockspace from the lockspace list and fail the request if it has been removed.

| * [DLM] Fix kref_put oopsPatrick Caulfield2006-11-061-1/+8
| | | | | | | | | | | | | | | | | | | | This patch fixes the recounting on the lockspace kobject. Previously the lockspace was freed while userspace could have had a reference to one of its sysfs files, causing an oops in kref_put. Now the lockspace kfree is moved into the kobject release() function Signed-Off-By: Patrick Caulfield <pcaulfie@redhat.com> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
| * [GFS2] Fix OOM error handlingSteven Whitehouse2006-11-061-0/+3

| * [GFS2] Fix incorrect fs sync behaviour.Steven Whitehouse2006-11-061-16/+28
| | | | | | | | | | | | | | | | | | | | | | | | This adds a sync_fs superblock operation for GFS2 and removes the journal flush from write_super in favour of sync_fs where it ought to be. This is more or less identical to the way in which ext3 does this.

* | [PATCH] sysctl: implement CTL_UNNUMBEREDEric W. Biederman2006-11-062-8/+0
|/ | | | | | | | | | | | | | This patch takes the CTL_UNNUMBERD concept from NFS and makes it available to all new sysctl users. At the same time the sysctl binary interface maintenance documentation is updated to mention and to describe what is needed to successfully maintain the sysctl binary interface.

| | | | | | | | | | | | | | | | The vfs handles most permissions for setting and retrieving xattrs. This patch removes a redundant and wrong check so that it won't override the correct behavior which is being fixed in the vfs. Signed-off-by: Dave Kleikamp <shaggy@austin.ibm.com>
