if kmalloc fails, we still need to drop the inode, as we do on other failure exits. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2010-08-09Fix reiserfs_file_release()Al Viro
a) count file openers correctly; i_count use was completely wrong b) use new mutex for exclusion between final close/open/truncate, to protect tailpacking logics. i_mutex use was wrong and resulted in deadlocks. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2010-08-09ecryptfs: dont call lookup_one_len to avoid NULL nameidataLino Sanfilippo
I have encountered the same problem that Eric Sandeen described in this post http://lkml.org/lkml/fancy/2010/4/23/467 while experimenting with stackable filesystems. The reason seems to be that ecryptfs calls lookup_one_len() to get the lower dentry, which in turn calls the lower parent dirs d_revalidate() with a NULL nameidata object. If ecryptfs is the underlaying filesystem, the NULL pointer dereference occurs, since ecryptfs is not prepared to handle a NULL nameidata. I know that this cant happen any more, since it is no longer allowed to mount ecryptfs upon itself. But maybe this patch it useful nevertheless, since the problem would still apply for an underlaying filesystem that implements d_revalidate() and is not prepared to handle a NULL nameidata (I dont know if there actually is such a fs). With this patch (against 2.6.35-rc5) ecryptfs uses the vfs_lookup_path() function instead of lookup_one_len() which ensures that the nameidata passed to the lower filesystems d_revalidate().

2010-08-09[S390] dasd: allocate fallback cqr for reserve/releaseStefan Weinhuber
The DASD reserve and release ioctls use the preallocated memory pool of the respective device to build their CCW requests. However, when the device is busy, the pool may already be empty and the ioctl fails. Usually this can be recovered by calling the ioctl again, but in a situation in which we need to issue an unconditional reserve to make a device operational again, this would be not recoverable. To avoid a failure due to lack of memory, DASD device driver will preallocate enough memory for a single reserve/release request, which can be used if normal allocation fails.

Commit 991ea75c (drm: use workqueue instead of slow-work), which made drm to use wq instead of slow-work, didn't account for the return value difference between delayed_slow_work_enqueue() and queue_delayed_work(). The former returns 0 on success and -errno on failures while the latter never fails and only uses the return value to indicate whether the work was already pending or not.

2010-08-08e100/e1000*/igb*/ixgb*: Add missing read memory barrierJeff Kirsher
Based on patches from Sonny Rao and Milton Miller... Combined the patches to fix up clean_tx_irq and clean_rx_irq. The PowerPC architecture does not require loads to independent bytes to be ordered without adding an explicit barrier. In ixgbe_clean_rx_irq we load the status bit then load the packet data. With packet split disabled if these loads go out of order we get a stale packet, but we will notice the bad sequence numbers and drop it. The problem occurs with packet split enabled where the TCP/IP header and data are in different descriptors. If the reads go out of order we may have data that doesn't match the TCP/IP header. Since we use hardware checksumming this bad data is never verified and it makes it all the way to the application. This bug was found during stress testing and adding this barrier has been shown to fix it. The bug can manifest as a data integrity issue (bad payload data) or as a BUG in skb_pull(). This was a nasty bug to hunt down, if people agree with the fix I think it's a candidate for stable. Previously Submitted to e1000-devel only for ixgbe http://marc.info/?l=e1000-devel&m=126593062701537&w=3 We've now seen this problem hit with other device drivers (e1000e mostly) So I'm resubmitting with fixes for other Intel Device Drivers with similar issues.
