2010-06-16Clear IFF_XMIT_DST_RELEASE for teql interfacesTom Hughes
https://bugzilla.kernel.org/show_bug.cgi?id=16183 The sch_teql module, which can be used to load balance over a set of underlying interfaces, stopped working after 2.6.30 and has been broken in all kernels since then for any underlying interface which requires the addition of link level headers. The problem is that the transmit routine relies on being able to access the destination address in the skb in order to do address resolution once it has decided which underlying interface it is going to transmit through. In 2.6.31 the IFF_XMIT_DST_RELEASE flag was introduced, and set by default for all interfaces, which causes the destination address to be released before the transmit routine for the interface is called. The solution is to clear that flag for teql interfaces. Signed-off-by: Tom Hughes <tom@compton.nu> Acked-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2010-06-16gianfar: Fix setup of RX time stampingManfred Rudigier
Previously the RCTRL_TS_ENABLE bit was set unconditionally. However, if the RCTRL_TS_ENABLE is set without TMR_CTRL[TE], the driver does not work properly on some boards (Anton had problems with the MPC8313ERDB and MPC8568EMDS). With this patch the bit will only be set if requested from user space with the SIOCSHWTSTAMP ioctl command, meaning that time stamping is disabled during normal operation. Users who are not interested in time stamps will not experience problems with buggy CPU revisions or performance drops any more. The setting of TMR_CTRL[TE] is still up to the user. This is considered safe because users wanting HW timestamps must initialize the eTSEC clock first anyway, e.g. with the recently submitted PTP clock driver.

2010-06-16cifs: remove bogus first_time check in NTLMv2 session setup codeJeff Layton
This bug appears to be the result of a cut-and-paste mistake from the NTLMv1 code. The function to generate the MAC key was commented out, but not the conditional above it. The conditional then ended up causing the session setup key not to be copied to the buffer unless this was the first session on the socket, and that made all but the first NTLMv2 session setup fail. Fix this by removing the conditional and all of the commented clutter that made it difficult to see.

2010-06-16cifs: don't call cifs_new_fileinfo unless cifs_open succeedsJeff Layton
It's currently possible for cifs_open to fail after it has already called cifs_new_fileinfo. In that situation, the new fileinfo will be leaked as the caller doesn't call fput. That in turn leads to a busy inodes after umount problem since the fileinfo holds an extra inode reference now. Shuffle cifs_open around a bit so that it only calls cifs_new_fileinfo if it's going to succeed.

2010-06-16cifs: pass instantiated filp back after open callJeff Layton
The current scheme of sticking open files on a list and assuming that cifs_open will scoop them off of it is broken and leads to "Busy inodes after umount..." errors at unmount time. The problem is that there is no guarantee that cifs_open will always be called after a ->lookup or ->create operation. If there are permissions or other problems, then it's quite likely that it *won't* be called. Fix this by fully instantiating the filp whenever the file is created and pass that filp back to the VFS. If there is a problem, the VFS can clean up the references. Signed-off-by: Jeff Layton <jlayton@redhat.com> Reviewed-and-Tested-by: Suresh Jayaraman <sjayaraman@suse.de>
2010-06-16cifs: move cifs_new_fileinfo call out of cifs_posix_openJeff Layton
Having cifs_posix_open call cifs_new_fileinfo is problematic and inconsistent with how "regular" opens work. It's also buggy as cifs_reopen_file calls this function on a reconnect, which creates a new struct cifsFileInfo that just gets leaked. Push it out into the callers. This also allows us to get rid of the "mnt" arg to cifs_posix_open. Finally, in the event that a cifsFileInfo isn't or can't be created, we always want to close the filehandle out on the server as the client won't have a record of the filehandle and can't actually use it. Make sure that CIFSSMBClose is called in those cases. Signed-off-by: Jeff Layton <jlayton@redhat.com> Reviewed-and-Tested-by: Suresh Jayaraman <sjayaraman@suse.de>
2010-06-16OMAP4: clock: Fix multi-omap boot with reset un-used clocksSantosh Shilimkar
This patch uses "ENABLE_ON_INIT" flag on the emif clock nodes to avoid the emif clk getting cut as part of reset un-used clock routine which prevents boot. Since "omap4xxx_clk_init()" calls "clk_enable_init_clocks()" which increases the usecount on all ENABLE_ON_INIT clocks, it prevents "omap2_clk_disable_unused()" from disabling the clock. The real fix is to have driver for EMIF and do clock get/enable as part of it. The EMIF driver is planned to be done HWMOD way so till that available to keep omap3_defconfig booting on OMAP4430, this patch is necessary.

In commit 6b82021b9e91cd689fdffadbcdb9a42597bbe764, we increase our local alloc size and calculate how much megabytes we can get according to group size and volume size. But we also need to check the maximum bits a local alloc block bitmap can have. With a bs=512, cs=32K, local volume with 160G, it calculate 96MB while the maximum local alloc size is only 76M. So the bitmap will overflow and corrupt the system truncate log file.

2010-06-15ocfs2: Move orphan scan work to ocfs2_wq.Tao Ma
We used to let orphan scan work in the default work queue, but there is a corner case which will make the system deadlock. The scenario is like this: 1. set heartbeat threadshold to 200. this will allow us to have a great chance to have a orphan scan work before our quorum decision. 2. mount node 1. 3. after 1~2 minutes, mount node 2(in order to make the bug easier to reproduce, better add maxcpus=1 to kernel command line). 4. node 1 do orphan scan work. 5. node 2 do orphan scan work. 6. node 1 do orphan scan work. After this, node 1 hold the orphan scan lock while node 2 know node 1 is the master. 7. ifdown eth2 in node 2(eth2 is what we do ocfs2 interconnection). Now when node 2 begins orphan scan, the system queue is blocked. The root cause is that both orphan scan work and quorum decision work will use the system event work queue. orphan scan has a chance of blocking the event work queue(in dlm_wait_for_node_death) so that there is no chance for quorum decision work to proceed. This patch resolve it by moving orphan scan work to ocfs2_wq. Signed-off-by: Tao Ma <tao.ma@oracle.com> Signed-off-by: Joel Becker <joel.becker@oracle.com>

2010-06-15ASoC: DaVinci: Fix McASP hardware FIFO configurationSudhakar Rajashekhara
On DA830/OMAP-L137 and DA850/OMAP-L138 SoCs, the McASP peripheral has FIFO support. This FIFO provides additional data buffering. It also provides tolerance to variation in host/DMA controller response times. More details of the FIFO operation can be found at http://focus.ti.com/general/docs/lit/getliterature.tsp?literatureNumber=sprufm1&fileType=pdf Existing sequence of steps for audio playback/capture are: a. DMA configuration b. McASP configuration (configures and enables FIFO) c. Start DMA d. Start McASP (enables FIFO) During McASP configuration, while FIFO was being configured, FIFO was being enabled in davinci_hw_common_param() function of sound/soc/davinci/davinci-mcasp.c file. This generated a transmit DMA event, which gets serviced when DMA is started. https://patchwork.kernel.org/patch/84611/ patch clears the DMA events before starting DMA, which is the right thing to do. But this resulted in a state where DMA was waiting for an event from McASP (after step c above), but the event which was already there, has got cleared (because of step b above). The fix is not to enable the FIFO during McASP configuration as FIFO was being enabled as part of McASP start.

2010-06-15kbuild: fix LOCALVERSION handling to match descriptionAndy Whitcroft
In the commit below the version string handling was modified, adding a '+' where no other version information was supplied: commit 85a256d8e0116c8f5ad276730830f5d4d473344d Author: David Rientjes <rientjes@google.com> Date: Wed Jan 13 13:01:05 2010 -0800 From the commit the intent was as below: - when CONFIG_LOCALVERSION_AUTO is disabled, a `+' is appended if the repository has been revised beyond a tagged commit and LOCALVERSION= was not passed to "make". However if the user supplies an empty LOCALVERSION on the command line the plus suffix is still added. This form is useful in the case where the build environment knows that the version as specified is correct and complete but does not correspond to a specific tag. This patch changes the implementation to match the documentation such that specifying LOCALVERSION= on the build line is sufficient to suppress any suffix.
