* reiserfs: strip trailing whitespaceJeff Mahoney2009-03-3019-184/+184
| | | | | | | This patch strips trailing whitespace from the reiserfs code. Signed-off-by: Jeff Mahoney <jeffm@suse.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* reiserfs: cleanup path functionsJeff Mahoney2009-03-302-74/+43
| | | | | | | | | | | | | | | This patch cleans up some redundancies in the reiserfs tree path code. decrement_bcount() is essentially the same function as brelse(), so we use that instead. decrement_counters_in_path() is exactly the same function as pathrelse(), so we kill that and use pathrelse() instead. There's also a bit of cleanup that makes the code a bit more readable. Signed-off-by: Jeff Mahoney <jeffm@suse.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* reiserfs: factor out buffer_info initializationJeff Mahoney2009-03-301-115/+60
| | | | | | | | | | | This is the first in a series of patches to make balance_leaf() not quite so insane. This patch factors out the open coded initializations of buffer_info structures and defines a few initializers for the 4 cases they're used.

* reiserfs: add atomic addition of selinux attributes during inode creationJeff Mahoney2009-03-305-6/+137
| | | | | | | | | | | | | Some time ago, some changes were made to make security inode attributes be atomically written during inode creation. ReiserFS fell behind in this area, but with the reworking of the xattr code, it's now fairly easy to add. The following patch adds the ability for security attributes to be added automatically during inode creation.

* reiserfs: use generic readdir for operations across all xattrsJeff Mahoney2009-03-303-300/+131
| | | | | | | | | | | | | | | | | | | | | | | | The current reiserfs xattr implementation open codes reiserfs_readdir and frees the path before calling the filldir function. Typically, the filldir function is something that modifies the file system, such as a chown or an inode deletion that also require reading of an inode associated with each direntry. Since the file system is modified, the path retained becomes invalid for the next run. In addition, it runs backwards in attempt to minimize activity. This is clearly suboptimal from a code cleanliness perspective as well as performance-wise. This patch implements a generic reiserfs_for_each_xattr that uses the generic readdir and a specific filldir routine that simply populates an array of dentries and then performs a specific operation on them. When all files have been operated on, it then calls the operation on the directory itself. The result is a noticable code reduction and better performance.

* reiserfs: journaled xattrsJeff Mahoney2009-03-307-49/+159
| | | | | | | | | | | | | | | | | | | Deadlocks are possible in the xattr code between the journal lock and the xattr sems. This patch implements journalling for xattr operations. The benefit is twofold: * It gets rid of the deadlock possibility by always ensuring that xattr write operations are initiated inside a transaction. * It corrects the problem where xattr backing files aren't considered any differently than normal files, despite the fact they are metadata. I discussed the added journal load with Chris Mason, and we decided that since xattrs (versus other journal activity) is fairly rare, the introduction of larger transactions to support journaled xattrs wouldn't be too big a deal.

* reiserfs: use generic xattr handlersJeff Mahoney2009-03-309-441/+258
| | | | | | | | | | | | | | | | | | | Christoph Hellwig had asked me quite some time ago to port the reiserfs xattrs to the generic xattr interface. This patch replaces the reiserfs-specific xattr handling code with the generic struct xattr_handler. However, since reiserfs doesn't split the prefix and name when accessing xattrs, it can't leverage generic_{set,get,list,remove}xattr without needlessly reconstructing the name on the back end. Update 7/26/07: Added missing dput() to deletion path. Update 8/30/07: Added missing mark_inode_dirty when i_mode is used to represent an ACL and no previous ACL existed.

* reiserfs: make per-inode xattr locking more fine grainedJeff Mahoney2009-03-304-90/+55
| | | | | | | | | | The per-inode locking can be made more fine-grained to surround just the interaction with the filesystem itself. This really only applies to protecting reads during a write, since concurrent writes are barred with inode->i_mutex at the vfs level.

* reiserfs: Clean up xattrs when REISERFS_FS_XATTR is unsetJeff Mahoney2009-03-304-357/+367
| | | | | | | | | | | | | | The current reiserfs xattr implementation will not clean up old xattr files if files are deleted when REISERFS_FS_XATTR is unset. This results in inaccessible lost files, wasting space. This patch compiles in basic xattr knowledge, such as how to delete them and change ownership for quota tracking. If the file system has never used xattrs, then the operation is quite fast: it returns immediately when it sees there is no .reiserfs_priv directory.

* reiserfs: audit transaction ids to always be unsigned intsJeff Mahoney2009-03-305-31/+31
| | | | | | | | | | | | | | | | | | This patch fixes up the reiserfs code such that transaction ids are always unsigned ints. In places they can currently be signed ints or unsigned longs. The former just causes an annoying clm-2200 warning and may join a transaction when it should wait. The latter is just for correctness since the disk format uses a 32-bit transaction id. There aren't any runtime problems that result from it not wrapping at the correct location since the value is truncated correctly even on big endian systems. The 0 value might make it to disk, but the mount-time checks will bump it to 10 itself. Signed-off-by: Jeff Mahoney <jeffm@suse.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a locking bug in the dm9000 driver. It calls request_irq() without setting IRQF_DISABLED ... which is correct for handlers that support IRQ sharing, since that behavior is not guaranteed for shared IRQs. However, its IRQ handler then wrongly assumes that IRQs are blocked. So the fix just uses the right spinlock primitives in the IRQ handler. NOTE: this is a classic example of the type of bug which lockdep currently masks by forcibly setting IRQF_DISABLED on IRQ handlers that did not request that flag.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | smsc911x_phy_adjust_link is called periodically by the phy layer (as it's run in polling mode), and it only updates the hardware when it sees a change in duplex or carrier. This patch clears the last known values every time the interface is brought up, instead of only when the module is loaded. Without this patch the adjust_link function never updates the hardware after an ifconfig down; ifconfig up. On a full duplex link this causes the tx error counter to increment, even though packets are correctly transmitted, as the default MAC_CR register setting is for half duplex. The tx errors are "no carrier" errors, which should be ignored in full-duplex mode. When MAC_CR is set to "full duplex" mode they are correctly ignored by the hardware. Note that even with this patch the tx error counter can increment if packets are transmitted between "ifconfig up" and the first phy poll interval. An improved solution would use the phy interrupt with phylib, but I haven't managed to make this work 100% robustly yet.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | dev can be NULL in ip[6]_frag_reasm for skb's coming from RAW sockets. Quagga's OSPFD sends fragmented packets on a RAW socket, when netfilter conntrack reassembles them on the OUTPUT path you hit this code path. You can test it with something like "hping2 -0 -d 2000 -f AA.BB.CC.DD" With help from Jarek Poplawski. Signed-off-by: Jorge Boncompte [DTI2] <jorge@dti2.net> Signed-off-by: David S.
