* Only send SIGXFSZ when exceeding rlimits.Micah Cowan2007-07-161-1/+0
| | | | | | | | | | | | | | | | | Some users have been having problems with utilities like cp or dd dumping core when they try to copy a file that's too large for the destination filesystem (typically, > 4gb). Apparently, some defunct standards required SIGXFSZ to be sent in such circumstances, but SUS only requires/allows it for when a written file exceeds the process's resource limits. I'd like to limit SIGXFSZs to the bare minimum required by SUS.

* slab allocators: Remove SLAB_DEBUG_INITIAL flagChristoph Lameter2007-05-071-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I have never seen a use of SLAB_DEBUG_INITIAL. It is only supported by SLAB. I think its purpose was to have a callback after an object has been freed to verify that the state is the constructor state again? The callback is performed before each freeing of an object. I would think that it is much easier to check the object state manually before the free. That also places the check near the code object manipulation of the object. Also the SLAB_DEBUG_INITIAL callback is only performed if the kernel was compiled with SLAB debugging on. If there would be code in a constructor handling SLAB_DEBUG_INITIAL then it would have to be conditional on SLAB_DEBUG otherwise it would just be dead code. But there is no such code in the kernel. I think SLUB_DEBUG_INITIAL is too problematic to make real use of, difficult to understand and there are easier ways to accomplish the same effect (i.e. add debug code before kfree). There is a related flag SLAB_CTOR_VERIFY that is frequently checked to be clear in fs inode caches. Remove the pointless checks (they would even be pointless without removeal of SLAB_DEBUG_INITIAL) from the fs constructors. This is the last slab flag that SLUB did not support. Remove the check for unimplemented flags from SLUB.

* mm: make read_cache_page synchronousNick Piggin2007-05-071-4/+0
| | | | | | | | | | | | | | | | Ensure pages are uptodate after returning from read_cache_page, which allows us to cut out most of the filesystem-internal PageUptodate calls. I didn't have a great look down the call chains, but this appears to fixes 7 possible use-before uptodate in hfs, 2 in hfsplus, 1 in jfs, a few in ecryptfs, 1 in jffs2, and a possible cleared data overwritten with readpage in block2mtd. All depending on whether the filler is async and/or can return with a !uptodate page.

* reiserfs: fix xattr root locking/refcount bugJeff Mahoney2007-04-241-68/+24
| | | | | | | | | | | | | | | | | | | | | | The listxattr() and getxattr() operations are only protected by a read lock. As a result, if either of these operations run in parallel, a race condition exists where the xattr_root will end up being cached twice, which results in the leaking of a reference and a BUG() on umount. This patch refactors get_xa_root(), __get_xa_root(), and create_xa_root(), into one get_xa_root() function that takes the appropriate locking around the entire critical section.

* [PATCH] reiserfs: fix key decrementingVladimir Saveliev2007-04-121-1/+1
| | | | | | | | | | | | | | | | This patch fixes a bug in function decrementing a key of stat data item. Offset of reiserfs keys are compared as signed values. To set key offset to maximal possible value maximal signed value has to be used.

* [PATCH] resierfs: avoid tail packing if an inode was ever mmappedVladimir Saveliev2007-01-232-1/+21
| | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes a confusion reiserfs has for a long time. On release file operation reiserfs used to try to pack file data stored in last incomplete page of some files into metadata blocks. After packing the page got cleared with clear_page_dirty. It did not take into account that the page may be mmaped into other process's address space. Recent replacement for clear_page_dirty cancel_dirty_page found the confusion with sanity check that page has to be not mapped. The patch fixes the confusion by making reiserfs avoid tail packing if an inode was ever mmapped. reiserfs_mmap and reiserfs_file_release are serialized with mutex in reiserfs specific inode. reiserfs_mmap locks the mutex and sets a bit in reiserfs specific inode flags. reiserfs_file_release checks the bit having the mutex locked. If bit is set - tail packing is avoided. This eliminates a possibility that mmapped page gets cancel_page_dirty-ed.

* [PATCH] reiserfs: reset errval after initializing bitmap cacheJeff Mahoney2006-11-031-0/+1
| | | | | | | | | | | | | | Callers after reiserfs_init_bitmap_cache() expect errval to contain -EINVAL until much later. If a condition fails before errval is reset later, reiserfs_fill_super() will mistakenly return 0, causing an Oops in do_add_mount(). This patch resets errval to -EINVAL after the call. I view this as a temporary fix and real error codes should be used throughout reiserfs_fill_super().

* [PATCH] separate bdi congestion functions from queue congestion functionsAndrew Morton2006-10-201-1/+2
| | | | | | | | | | | | | | | | | | | Separate out the concept of "queue congestion" from "backing-dev congestion". Congestion is a backing-dev concept, not a queue concept. The blk_* congestion functions are retained, as wrappers around the core backing-dev congestion functions. This proper layering is needed so that NFS can cleanly use the congestion functions, and so that CONFIG_BLOCK=n actually links.

* [PATCH] ReiserFS: Make sure all dentries refs are released before calling ↵David Howells2006-10-111-11/+20
| | | | | | | | | | | | | | | | | | | | | | kill_block_super() Make sure all dentries refs are released before calling kill_block_super() so that the assumption that generic_shutdown_super() can completely destroy the dentry tree for there will be no external references holds true. What was being done in the put_super() superblock op, is now done in the kill_sb() filesystem op instead, prior to calling kill_block_super(). Changes made in [try #2]: (*) reiserfs_kill_sb() now checks that the superblock FS info pointer is set before trying to dereference it.

* [PATCH] VFS: Make filldir_t and struct kstat deal in 64-bit inode numbersDavid Howells2006-10-031-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These patches make the kernel pass 64-bit inode numbers internally when communicating to userspace, even on a 32-bit system. They are required because some filesystems have intrinsic 64-bit inode numbers: NFS3+ and XFS for example. The 64-bit inode numbers are then propagated to userspace automatically where the arch supports it. Problems have been seen with userspace (eg: ld.so) using the 64-bit inode number returned by stat64() or getdents64() to differentiate files, and failing because the 64-bit inode number space was compressed to 32-bits, and so overlaps occur. This patch: Make filldir_t take a 64-bit inode number and struct kstat carry a 64-bit inode number so that 64-bit inode numbers can be passed back to userspace. The stat functions then returns the full 64-bit inode number where available and where possible. If it is not possible to represent the inode number supplied by the filesystem in the field provided by userspace, then error EOVERFLOW will be issued. Similarly, the getdents/readdir functions now pass the full 64-bit inode number to userspace where possible, returning EOVERFLOW instead when a directory entry is encountered that can't be properly represented. Note that this means that some inodes will not be stat'able on a 32-bit system with old libraries where they were before - but it does mean that there will be no ambiguity over what a 32-bit inode number refers to. Note similarly that directory scans may be cut short with an error on a 32-bit system with old libraries where the scan would work before for the same reasons. It is judged unlikely that this situation will occur because modern glibc uses 64-bit capable versions of stat and getdents class functions exclusively, and that older systems are unlikely to encounter unrepresentable inode numbers anyway.

* [PATCH] r/o bind mounts: unlink: monitor i_nlinkDave Hansen2006-10-011-3/+3
| | | | | | | | | | | | | | | | | When a filesystem decrements i_nlink to zero, it means that a write must be performed in order to drop the inode from the filesystem. We're shortly going to have keep filesystems from being remounted r/o between the time that this i_nlink decrement and that write occurs. So, add a little helper function to do the decrements. We'll tie into it in a bit to note when i_nlink hits zero.
