commit 2363d196 upstream. This patch fixes a iser-target specific regression introduced in v3.15-rc6 with: commit 14f4b54f Author: Sagi Grimberg <sagig@mellanox.com> Date: Tue Apr 29 13:13:47 2014 +0300 Target/iscsi,iser: Avoid accepting transport connections during stop stage where the change to set iscsi_np->enabled = false within iscsit_clear_tpg_np_login_thread() meant that a iscsi_np with two iscsi_tpg_np exports would have it's parent iscsi_np set to a disabled state, even if other iscsi_tpg_np exports still existed. This patch changes iscsit_clear_tpg_np_login_thread() to only set iscsi_np->enabled = false when shutdown = true, and also changes iscsit_del_np() to set iscsi_np->enabled = true when iscsi_np->np_exports is non zero.

commit 14f4b54f upstream. When the target is in stop stage, iSER transport initiates RDMA disconnects. The iSER initiator may wish to establish a new connection over the still existing network portal. In this case iSER transport should not accept and resume new RDMA connections. In order to learn that, iscsi_np is added with enabled flag so the iSER transport can check when deciding weather to accept and resume a new connection request. The iscsi_np is enabled after successful transport setup, and disabled before iscsi_np login threads are cleaned up. (Fix up context changes for v3.10.y - nab) Signed-off-by:

commit 895162b1 upstream. else we may fail to forward skb even if original fragments do fit outgoing link mtu: 1. remote sends 2k packets in two 1000 byte frags, DF set 2. we want to forward but only see '2k > mtu and DF set' 3. we then send icmp error saying that outgoing link is 1500 But original sender never sent a packet that would not fit the outgoing link. Setting local_df makes outgoing path test size vs. IPCB(skb)->frag_max_size, so we will still send the correct error in case the largest original size did not fit outgoing link mtu. Reported-by:

commit 6e20bae8 upstream. The mvebu-devbus driver had a serious bug, which lead to a 8 bits bus width declared in the Device Tree being considered as a 16 bits bus width when configuring the hardware. This bug in mvebu-devbus driver was compensated by a symetric mistake in the Armada XP OpenBlocks AX3 Device Tree: a 8 bits bus width was declared, even though the hardware actually has a 16 bits bus width connection with the NOR flash. Now that we have fixed the mvebu-devbus driver to behave according to its Device Tree binding, this commit fixes the problematic Device Tree files as well. This bug was introduced in commit a7d4f818 ('ARM: mvebu: Add support for NOR flash device on Openblocks AX3 board') which was merged in v3.10. Signed-off-by:

commit 23adbe12 upstream. The kernel has no concept of capabilities with respect to inodes; inodes exist independently of namespaces. For example, inode_capable(inode, CAP_LINUX_IMMUTABLE) would be nonsense. This patch changes inode_capable to check for uid and gid mappings and renames it to capable_wrt_inode_uidgid, which should make it more obvious what it does. Fixes CVE-2014-4014.

It returns the remainder of the division and this was not what the function expected leading to disabling the interrupt latency watchdog.

commit 14c63f17 upstream. This patch keeps track of how long perf's NMI handler is taking, and also calculates how many samples perf can take a second. If the sample length times the expected max number of samples exceeds a configurable threshold, it drops the sample rate. This way, we don't have a runaway sampling process eating up the CPU. This patch can tend to drop the sample rate down to level where perf doesn't work very well. *BUT* the alternative is that my system hangs because it spends all of its time handling NMIs. I'll take a busted performance tool over an entire system that's busted and undebuggable any day. BTW, my suspicion is that there's still an underlying bug here. Using the HPET instead of the TSC is definitely a contributing factor, but I suspect there are some other things going on. But, I can't go dig down on a bug like that with my machine hanging all the time. Signed-off-by:

commit 6cc44a6f upstream. This patch addresses a bug where an early exception for SCSI WRITE with ImmediateData=Yes was missing the target_put_sess_cmd() call to drop the extra se_cmd->cmd_kref reference obtained during the normal iscsit_setup_scsi_cmd() codepath execution. This bug was manifesting itself during session shutdown within isert_cq_rx_comp_err() where target_wait_for_sess_cmds() would end up waiting indefinately for the last se_cmd->cmd_kref put to occur for the failed SCSI WRITE + ImmediateData descriptors. This fix follows what traditional iscsi-target code already does for the same failure case within iscsit_get_immediate_data(). Reported-by:

commit 624483f3 upstream. While working address sanitizer for kernel I've discovered use-after-free bug in __put_anon_vma. For the last anon_vma, anon_vma->root freed before child anon_vma. Later in anon_vma_free(anon_vma) we are referencing to already freed anon_vma->root to check rwsem. This fixes it by freeing the child anon_vma before freeing anon_vma->root. Signed-off-by:

commit 8ef42ddd upstream. Not all host controller drivers have bus-suspend and bus-resume methods. When one doesn't, it will cause problems if runtime PM is enabled in the kernel. The PM core will attempt to suspend the controller's root hub, the suspend will fail because there is no bus-suspend routine, and a -EBUSY error code will be returned to the PM core. This will cause the suspend attempt to be repeated shortly thereafter, in a never-ending loop. Part of the problem is that the original error code -ENOENT gets changed to -EBUSY in usb_runtime_suspend(), on the grounds that the PM core will interpret -ENOENT as meaning that the root hub has gotten into a runtime-PM error state. While this change is appropriate for real USB devices, it's not such a good idea for a root hub. In fact, considering the root hub to be in a runtime-PM error state would not be far from the truth. Therefore this patch updates usb_runtime_suspend() so that it adjusts error codes only for non-root-hub devices. Furthermore, the patch attempts to prevent the problem from occurring in the first place by not enabling runtime PM by default for root hubs whose host controller driver doesn't have bus_suspend and bus_resume methods.

commit c03890ff upstream. A recent patch that purported to fix firmware download on big-endian machines failed to add the corresponding sparse annotation to the i2c-header. This was reported by the kbuild test robot. Adding the appropriate annotation revealed another endianess bug related to the i2c-header Size-field in a code path that is exercised when the firmware is actually being downloaded (and not just verified and left untouched unless older than the firmware at hand). This patch adds the required sparse annotation to the i2c-header and makes sure that the Size-field is sent in little-endian byte order during firmware download also on big-endian machines. Note that this patch is only compile-tested, but that there is no functional change for little-endian systems. Reported-by:

commit d7500135 upstream.

commit 2ac295a5 upstream. Commit 8313b8e5 md: fix problem when adding device to read-only array with bitmap. added a called to md_reap_sync_thread() which cause a reshape thread to be interrupted (in particular, it could cause md_thread() to never even call md_do_sync()). However it didn't set MD_RECOVERY_INTR so ->finish_reshape() would not know that the reshape didn't complete. This only happens when mddev->ro is set and normally reshape threads don't run in that situation. But raid5 and raid10 can start a reshape thread during "run" is the array is in the middle of a reshape. They do this even if ->ro is set. So it is best to set MD_RECOVERY_INTR before abortingg the sync thread, just in case. Though it rare for this to trigger a problem it can cause data corruption because the reshape isn't finished properly. So it is suitable for any stable which the offending commit was applied to.

commit 3991b31e upstream. If mddev->ro is set, md_to_sync will (correctly) abort. However in that case MD_RECOVERY_INTR isn't set. If a RESHAPE had been requested, then ->finish_reshape() will be called and it will think the reshape was successful even though nothing happened. Normally a resync will not be requested if ->ro is set, but if an array is stopped while a reshape is on-going, then when the array is started, the reshape will be restarted. If the array is also set read-only at this point, the reshape will instantly appear to success, resulting in data corruption. Consequently, this patch is suitable for any -stable kernel.

commit 9aab8bff upstream. We only want to modifiy a single field in the userspace view of the execbuffer command buffer, so explicitly change that rather than copy everything back again. This serves two purposes: 1. The single fields are much cheaper to copy (constant size so the copy uses special case code) and much smaller than the whole array. 2. We modify the array for internal use that need to be masked from the user. Note: We need this backported since without it the next bugfix will blow up when userspace recycles batchbuffers and relocations. Signed-off-by:

commit 4b353a70 upstream. On OMAP4 panda board, there have been several bug reports about boot hang and lock-ups with CPU_IDLE enabled. The root cause of the issue is missing interrupts while in idle state. Commit cb7094e8 {cpuidle / omap4 : use CPUIDLE_FLAG_TIMER_STOP flag} moved the broadcast notifiers to common code for right reasons but on OMAP4 which suffers from a nasty ROM code bug with GIC, commit ff999b8a {ARM: OMAP4460: Workaround for ROM bug ..}, we loose interrupts which leads to issues like lock-up, hangs etc. Patch reverts commit cb7094 {cpuidle / omap4 : use CPUIDLE_FLAG_TIMER_STOP flag} and 54769d65 {cpuidle: OMAP4: remove timer broadcast initialization} to avoid the issue. With this change, OMAP4 panda boards, the mentioned issues are getting fixed. We no longer loose interrupts which was the cause of the regression.

commit ead82d67 upstream. The mapping from OF device IDs to platform device IDs is wrong. TYPE_NCPXXWB473 is 0, TYPE_NCPXXWL333 is 1, so ntc_thermistor_id[TYPE_NCPXXWB473] is { "ncp15wb473", TYPE_NCPXXWB473 } while ntc_thermistor_id[TYPE_NCPXXWL333] is { "ncp18wb473", TYPE_NCPXXWB473 }. So the name is wrong for all but the "ntc,ncp15wb473" entry, and the type is wrong for the "ntc,ncp15wl333" entry. So map the entries by index, it is neither elegant nor robust but at least it is correct. Signed-off-by:

commit 59cf4243 upstream. In commit 9e8269de, support was added for ntc_thermistor devices being declared in the device tree and implemented on top of IIO. With that change, a dependency was added to the ntc_thermistor driver: depends on (!OF && !IIO) || (OF && IIO) This construct has the drawback that the driver can no longer be selected when OF is set and IIO isn't, nor when IIO is set and OF is not. This is a regression for the original users of the driver. As the new code depends on IIO and is useless without OF, include it only if both are enabled, and set the dependencies accordingly. This is clearer, more simple and more correct. Signed-off-by:
