* [PATCH] hugetlb: prepare_hugepage_range check offset tooHugh Dickins2006-11-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (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.

* [PATCH] autofs4: panic after mount failIan Kent2006-11-14
| | | | | | | | | | | | | | 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 first a NULL pointer reference to a field (pipe) in the autofs superblock info structure and second the lack of super block cleanup by the autofs and autofs4 modules.

| * [XFS] Prevent a deadlock when xfslogd unpins inodes.David Chinner2006-11-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

I ran into this too because of an old source tree, but my fix would look quite a bit different to Andi's fix. The reason is that the compat function IMHO should behave the very same as the non-compat function if possible. Since sys_pselect7 does not return -EFAULT in this specific case, change the compat code so it behaves like sys_pselect7.

* | [PATCH] eCryptfs: Consolidate lower dentry_open'sMichael Halcrow2006-10-31
| | | | | | | | | | | | | | | | | | | | Opens on lower dentry objects happen in several places in eCryptfs, and they all involve the same steps (dget, mntget, dentry_open). This patch consolidates the lower open events into a single function call.

* | [PATCH] clean up add_bd_holder()Jun'ichi Nomura2006-10-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | add_bd_holder() is called from bd_claim_by_kobject to put a given struct bd_holder in the list if there is no matching entry. There are 3 possible results of add_bd_holder(): 1. there is no matching entry and add the given one to the list 2. there is matching entry, so just increment reference count of the existing one 3. something failed during its course 1 and 2 are successful cases. But for case 2, someone has to free the unused struct bd_holder. The current code frees it inside of add_bd_holder and returns same value 0 for both cases 1 and 2. However, it's natural and less error-prone if caller frees it since it's allocated by the caller.
