2013-09-03vfs: allow umount to handle mountpoints without revalidating themJeff Layton3-1/+184
Christopher reported a regression where he was unable to unmount a NFS filesystem where the root had gone stale. The problem is that d_revalidate handles the root of the filesystem differently from other dentries, but d_weak_revalidate does not. We could simply fix this by making d_weak_revalidate return success on IS_ROOT dentries, but there are cases where we do want to revalidate the root of the fs. A umount is really a special case. We generally aren't interested in anything but the dentry and vfsmount that's attached at that point. If the inode turns out to be stale we just don't care since the intent is to stop using it anyway. Try to handle this situation better by treating umount as a special case in the lookup code. Have it resolve the parent using normal means, and then do a lookup of the final dentry without revalidating it. In most cases, the final lookup will come out of the dcache, but the case where there's a trailing symlink or !LAST_NORM entry on the end complicates things a bit.

2013-09-03vfs: call d_op->d_prune() before unhashing dentryYan, Zheng1-2/+11
The d_prune dentry operation is used to notify filesystem when VFS about to prune a hashed dentry from the dcache. There are three code paths that prune dentries: shrink_dcache_for_umount_subtree(), prune_dcache_sb() and d_prune_aliases(). For the d_prune_aliases() case, VFS unhashes the dentry first, then call the d_prune dentry operation. This confuses ceph_d_prune() (ceph uses the d_prune dentry operation to maintain a flag indicating whether the complete contents of a directory are in the dcache, pruning unhashed dentry does not affect dir's completeness) This patch fixes the issue by calling the d_prune dentry operation in d_prune_aliases(), before unhashing the dentry. Also make VFS only call the d_prune dentry operation for hashed dentry, to avoid calling the d_prune dentry operation twice when dentry is pruned by d_prune_aliases().

2013-09-03vhost_net: correctly limit the max pending buffersJason Wang1-11/+7
As Michael point out, We used to limit the max pending DMAs to get better cache utilization. But it was not done correctly since it was one done when there's no new buffers submitted from guest. Guest can easily exceeds the limitation by keeping sending packets. So this patch moves the check into main loop. Tests shows about 5%-10% improvement on per cpu throughput for guest tx.

We tend to batch the used adding and signaling in vhost_zerocopy_callback() which may result more than 100 used buffers to be updated in vhost_zerocopy_signal_used() in some cases. So switch to use vhost_add_used_and_signal_n() to avoid multiple calls to vhost_add_used_and_signal(). Which means much less times of used index updating and memory barriers. 2% performance improvement were seen on netperf TCP_RR test.

2013-09-03net: calxedaxgmac: fix various errors in xgmac_set_rx_modeRob Herring1-4/+13
Fix xgmac_set_rx_mode to handle several conditions that were not handled correctly as Lennert Buytenhek describes: If we have, say, 100 unicast addresses, and 5 multicast addresses, the unicast address count check will evaluate to true, and set use_hash to true. The multicast address check will however evaluate to false, and use_hash won't be set to true again, and XGMAC_FRAME_FILTER_HMC won't be OR'd into XGMAC_FRAME_FILTER, but since use_hash was still true from the unicast check, netdev_for_each_mc_addr() will program the multicast addresses into the hash table instead of using the MAC address registers, but since the HMC bit wasn't set, the hash table won't be checked for multicast addresses on receive, and we'll stop receiving multicast packets entirely. Also, there is no code that zeroes out MAC address registers reg..31 at the end of this function, meaning that under the right conditions, unicast/multicast addresses that were previously in the filter but were then deleted won't be cleared out.

2013-09-03net: calxedaxgmac: fix race with tx queue stop/wakeRob Herring1-5/+15
Since the xgmac transmit start and completion work locklessly, it is possible for xgmac_xmit to stop the tx queue after the xgmac_tx_complete has run resulting in the tx queue never being woken up. Fix this by ensuring that ring buffer index updates are visible and recheck the ring space after stopping the queue. Also fix an off-by-one bug where we need to stop the queue when the ring buffer space is equal to MAX_SKB_FRAGS. The implementation used here was copied from drivers/net/ethernet/broadcom/tg3.c.

Now set the skb pointer on every entry in the ring, not just the head of the sg list. We then use the FS (first segment) bit in the descriptors to determine skb head vs. fragment.

2013-09-03gianfar: Fix reported number of sent bytes to BQLClaudiu Manoil2-8/+12
Fix the amount of sent bytes reported to BQL by reporting the number of bytes on wire in the xmit routine, and recording that value for each skb in order to be correctly confirmed on Tx confirmation cleanup. Reporting skb->len to BQL just before exiting xmit is not correct due to possible insertions of TOE block and alignment bytes in the skb->data, which are being stripped off by the controller before transmission on wire. This led to mismatch of (incorrectly) reported bytes to BQL b/w xmit and Tx confirmation, resulting in Tx timeout firing, for the h/w tx timestamping acceleration case. There's no easy way to obtain the number of bytes on wire in the Tx confirmation routine, so skb->cb is used to convey that information from xmit to Tx confirmation, for now (as proposed by Eric).

When my 'ifup eth' script was fired multiple times and ran concurrent on my laptop, for some obscure /etc scripting reason, it was revealed that the store_enabled() function in netconsole doesn't handle it nicely, as recorded by the Oops below (a syslog paste, but not mangled too much to prevent from discerning the traceback). On Linux 3.10.4, this patch seeks to remedy the problem, and it has been running stable on my laptop for a few days.
