2011-07-14net: remove NETIF_F_ALL_TX_OFFLOADSMichał Mirosław
There is no software fallback implemented for SCTP or FCoE checksumming, and so it should not be passed on by software devices like bridge or bonding. For VLAN devices, this is different. First, the driver for underlying device should be prepared to get offloaded packets even when the feature is disabled (especially if it advertises it in vlan_features). Second, devices under VLANs do not get replaced without tearing down the VLAN first. This fixes a mess I accidentally introduced while converting bonding to ndo_fix_features. NETIF_F_SOFT_FEATURES are removed from BOND_VLAN_FEATURES because they are unused as of commit 712ae51afd. Signed-off-by: Michał Mirosław <mirq-linux@rere.qmqm.pl> Signed-off-by: David S.

2011-07-14net: sctp: fix checksum marking for outgoing packetsMichał Mirosław
Packets to devices without NETIF_F_SCTP_CSUM (including NETIF_F_NO_CSUM) should be properly checksummed because the packets can be diverted or rerouted after construction. This still leaves packets diverted from NETIF_F_SCTP_CSUM-enabled devices with broken checksums. Fixing this needs implementing software offload fallback in networking core. For users of sctp_checksum_disable, skb->ip_summed should be left as CHECKSUM_NONE and not CHECKSUM_UNNECESSARY as per include/linux/skbuff.h.

2011-07-14GFS2: Resolve inode eviction and ail list interaction bugSteven Whitehouse
This patch contains a few misc fixes which resolve a recently reported issue. This patch has been a real team effort and has received a lot of testing. The first issue is that the ail lock needs to be held over a few more operations. The lock thats added into gfs2_releasepage() may possibly be a candidate for replacing with RCU at some future point, but at this stage we've gone for the obvious fix. The second issue is that gfs2_write_inode() can end up calling a glock recursively when called from gfs2_evict_inode() via the syncing code, so it needs a guard added. The third issue is that we either need to not truncate the metadata pages of inodes which have zero link count, but which we cannot deallocate due to them still being in use by other nodes, or we need to ensure that those pages have all made it through the journal and ail lists first. This patch takes the former approach, but the latter has also been tested and there is nothing to choose between them performance-wise. So again, we could revise that decision in the future. Also, the inode eviction process is now better documented.

2011-07-13[media] dvb_frontend: fix race condition in stopping/starting frontendDevin Heitmueller
Attached is a patch which addresses a race condition in the DVB core related to closing/reopening the DVB frontend device in quick succession. This is the reason that devices such as the HVR-1300, HVR-3000, and HVR-4000 have been failing to scan properly under MythTV and w_scan. The gory details of the race are described in the patch. Devin There is a race condition exhibited when channel scanners such as w_scan and MythTV quickly close and then reopen the frontend device node. Under normal conditions, the behavior is as follows: 1. Application closes the device node 2. DVB frontend ioctl calls dvb_frontend_release which sets fepriv->release_jiffies 3. DVB frontend thread *eventually* calls dvb_frontend_is_exiting() which compares fepriv->release_jiffies, and shuts down the thread if timeout has expired 4. Thread goes away 5. Application opens frontend device 6. DVB frontend ioctl() calls ts_bus_ctrl(1) 7. DVB frontend ioctl() creates new frontend thread, which calls dvb_frontend_init(), which has demod driver init() routine setup initial register state for demod chip. 8. Tuning request is issued. The race occurs when the application in step 5 performs the new open() call before the frontend thread is shutdown. In this case the ts_bus_ctrl() call is made, which strobes the RESET pin on the demodulator, but the dvb_frontend_init() function never gets called because the frontend thread hasn't gone away yet. As a result, the initial register config for the demod is *never* setup, causing subsequent tuning requests to fail. If there is time between the close and open (enough for the dvb frontend thread to be torn down), then in that case the new frontend thread is created and thus the dvb_frontend_init() function does get called. The fix is to set the flag which forces reinitialization if we did in fact call ts_bus_ctrl(). This problem has been seen on the HVR-1300, HVR-3000, and HVR-4000, and is likely occuring on other designs as well where ts_bus_ctrl() actually strobes the reset pin on the demodulator. Note that this patch should supercede any patches submitted for the 1300/3000/4000 which remove the code that removes GPIO code in cx8802_dvb_advise_acquire(), which have been circulating by users for some time now...

2011-07-13ACPI: Fix lockdep false positives in acpi_power_off()Rafael J. Wysocki
All ACPICA locks are allocated by the same function, acpi_os_create_lock(), with the help of a local variable called "lock". Thus, when lockdep is enabled, it uses "lock" as the name of all those locks and regards them as instances of the same lock, which causes it to report possible locking problems with them when there aren't any. To work around this problem, define acpi_os_create_lock() as a macro and make it pass its argument to spin_lock_init(), so that lockdep uses it as the name of the new lock. Define this macron in a Linux-specific file, to minimize the resulting modifications of the OS-independent ACPICA parts. This change is based on an earlier patch from Andrea Righi and it addresses a regression from 2.6.39 tracked as https://bugzilla.kernel.org/show_bug.cgi?id=38152 Signed-off-by: Rafael J.

2011-07-13rcu: Prevent RCU callbacks from executing before scheduler initializedPaul E. McKenney
Under some rare but real combinations of configuration parameters, RCU callbacks are posted during early boot that use kernel facilities that are not yet initialized. Therefore, when these callbacks are invoked, hard hangs and crashes ensue. This commit therefore prevents RCU callbacks from being invoked until after the scheduler is fully up and running, as in after multiple tasks have been spawned. It might well turn out that a better approach is to identify the specific RCU callbacks that are causing this problem, but that discussion will wait until such time as someone really needs an RCU callback to be invoked (as opposed to merely registered) during early boot.
