git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-next Jeff Kirsher says: ==================== This series contains updates to e1000, e1000e, igb, igbvf and ixgbe. The e1000, e1000e, igb and igbvf are single patch changes and the remaining 11 patches are all against ixgbe. The e1000 patch is a comment cleanup to align e1000 with the code commenting style for /drivers/net. It also contains a few other white space cleanups (i.e. fix lines over 80 char, remove unnecessary blank lines and fix the use of tabs/spaces). The e1000e patch from Koki (Fujitsu) adds a warning when link speed is downgraded due to SmartSpeed. The igb patch from Stefan (Red Hat) increases the timeout in the ethtool offline self-test because some i350 adapters would sometimes fail the self-test because link auto negotiation may take longer than the current 4 second timeout. The igbvf patch from Alex is meant to address several race issues that become possible because next_to_watch could possibly be set to a value that shows that the descriptor is done when it is not. In order to correct that we instead make next_to_watch a pointer that is set to NULL during cleanup, and set to the eop_desc after the descriptor rings have been written. The remaining patches for ixgbe are a mix of fixes and added support as well as some cleanup. Most notably is the added support for displaying the number of Tx/Rx channels via ethtool by Alex. Also Aurélien adds the ability for reading data from SFP+ modules over i2c for diagnostic monitoring. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2013-02-18cgroup: fail if monitored file and event_control are in different cgroupLi Zefan1-0/+11
If we pass fd of memory.usage_in_bytes of cgroup A to cgroup.event_control of cgroup B, then we won't get memory usage notification from A but B!

This is is the case only for drivers that don't support TDLS, where any kind of change, even just the change of authorized flag that is required for normal operation, was rejected now.

2013-02-18cgroup: fix cgroup_rmdir() vs close(eventfd) raceLi Zefan1-16/+25
commit 205a872bd6f9a9a09ef035ef1e90185a8245cc58 ("cgroup: fix lockdep warning for event_control") solved a deadlock by introducing a new bug. Move cgrp->event_list to a temporary list doesn't mean you can traverse this list locklessly, because at the same time cgroup_event_wake() can be called and remove the event from the list. The result of this race is disastrous. We adopt the way how kvm irqfd code implements race-free event removal, which is now described in the comments in cgroup_event_wake(). v3: - call eventfd_signal() no matter it's eventfd close or cgroup removal that removes the cgroup event.

The result of this race can be worse than seeing partially rewritten name, but we might access a stale pointer because rename() will re-allocate memory to hold a longer name.

2013-02-18NFSv4.1: Don't decode skipped layoutgetsWeston Andros Adamson1-1/+2
layoutget's prepare hook can call rpc_exit with status = NFS4_OK (0). Because of this, nfs4_proc_layoutget can't depend on a 0 status to mean that the RPC was successfully sent, received and parsed. To fix this, use the result's len member to see if parsing took place. This fixes the following OOPS -- calling xdr_init_decode() with a buffer length 0 doesn't set the stream's 'p' member and ends up using uninitialized memory in filelayout_decode_layout.

2013-02-18Revert "of: use platform_device_add"Grant Likely1-11/+2
This reverts commit aac73f34542bc7ae4317928d2eabfeb21d247323. That commit causes two kinds of breakage; it breaks registration of AMBA devices when one of the parent nodes already contains overlapping resource regions, and it breaks calls to request_region() by device drivers in certain conditions where there are overlapping memory regions. Both of these problems can probably be fixed, but it is better to back out the commit and get a proper fix designed before trying again. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

2013-02-17generic-adc-battery: Fix forever loop in gab_remove()Dan Carpenter1-7/+9
There is a forever loop calling iio_channel_release() because the "chan < " part of the "chan < ARRAY_SIZE()" is missing. This is in both the error handling on probe and also in the remove function. The other thing is that it's possible for some of the elements of the adc_bat->channel[chan] array to be an ERR_PTR(). I've changed them to be NULL instead. We're still not allowed to pass NULLs to iio_channel_release() so I've added a check. Finally, I removed an unused "chan = ARRAY_SIZE(gab_chan_name);" statement as a small cleanup.
