commit df150ed1 upstream. We don't log remote attribute contents, and instead write them synchronously before we commit the block allocation and attribute tree update transaction. As a result we are writing to the allocated space before the allcoation has been made permanent. As a result, we cannot consider this allocation to be a metadata allocation. Metadata allocation can take blocks from the free list and so reuse them before the transaction that freed the block is committed to disk. This behaviour is perfectly fine for journalled metadata changes as log recovery will ensure the free operation is replayed before the overwrite, but for remote attribute writes this is not the case. Hence we have to consider the remote attribute blocks to contain data and allocate accordingly. We do this by dropping the XFS_BMAPI_METADATA flag from the block allocation. This means the allocation will not use blocks that are on the busy list without first ensuring that the freeing transaction has been committed to disk and the blocks removed from the busy list. This ensures we will never overwrite a freed block without first ensuring that it is really free. Signed-off-by:

commit b9d9c9ef upstream. Toshiba Satellite S50D has another model with a different PCI SSID (1179:fa93) while the previous fixup was for 1179:fa91. Adjust the fixup entry with SND_PCI_QUIRK_MASK() to match with both devices. Reported-by:

commit 007d038b upstream. This patch fixes a regression introduced with the following commit in v4.0-rc1 code, where an explicit iser-target logout would result in ->tx_thread_active being incorrectly cleared by the logout post handler, and subsequent TX kthread leak: commit 88dcd2da Author: Nicholas Bellinger <nab@linux-iscsi.org> Date: Thu Feb 26 22:19:15 2015 -0800 iscsi-target: Convert iscsi_thread_set usage to kthread.h To address this bug, change iscsit_logout_post_handler_closesession() and iscsit_logout_post_handler_samecid() to only cmpxchg() on ->tx_thread_active for traditional iscsi/tcp connections. This is required because iscsi/tcp connections are invoking logout post handler logic directly from TX kthread context, while iser connections are invoking logout post handler logic from a seperate workqueue context.

commit e5419865 upstream. This patch fixes a regression introduced with the following commit in v4.0-rc1 code, where a iscsit_start_kthreads() failure triggers a NULL pointer dereference OOPs: commit 88dcd2da Author: Nicholas Bellinger <nab@linux-iscsi.org> Date: Thu Feb 26 22:19:15 2015 -0800 iscsi-target: Convert iscsi_thread_set usage to kthread.h To address this bug, move iscsit_start_kthreads() immediately preceeding the transmit of last login response, before signaling a successful transition into full-feature-phase within existing iscsi_target_do_tx_login_io() logic. This ensures that no target-side resource allocation failures can occur after the final login response has been successfully sent. Also, it adds a iscsi_conn->rx_login_comp to allow the RX thread to sleep to prevent other socket related failures until the final iscsi_post_login_handler() call is able to complete.

commit 417c20a9 upstream. This patch fixes a use-after-free bug in iscsit_release_sessions_for_tpg() where se_portal_group->session_lock was incorrectly released/re-acquired while walking the active se_portal_group->tpg_sess_list. The can result in a NULL pointer dereference when iscsit_close_session() shutdown happens in the normal path asynchronously to this code, causing a bogus dereference of an already freed list entry to occur. To address this bug, walk the session list checking for the same state as before, but move entries to a local list to avoid dropping the lock while walking the active list. As before, signal using iscsi_session->session_restatement=1 for those list entries to be released locally by iscsit_free_session() code. Reported-by:

commit 9a258afa upstream. For hwmods without sysc, _init_mpu_rt_base(oh) won't be called and so _find_mpu_rt_port(oh) will return NULL thus preventing ready state check on those modules after the module is enabled. This can potentially cause a bus access error if the module is accessed before the module is ready. Fix this by unconditionally calling _init_mpu_rt_base() during hwmod _init(). Do ioremap only if we need SYSC access. Eventhough _wait_target_ready() check doesn't really need MPU RT port but just the PRCM registers, we still mandate that the hwmod must have an MPU RT port if ready state check needs to be done. Else it would mean that the module is not accessible by MPU so there is no point in waiting for target to be ready. e.g. this fixes the below DCAN bus access error on AM437x-gp-evm.

commit 06f6d109 upstream.

commit 0848f642 upstream. When ip_frag_queue() computes positions, it assumes that the passed sk_buff does not contain L2 headers. However, when PACKET_FANOUT_FLAG_DEFRAG is used, IP reassembly functions can be called on outgoing packets that contain L2 headers. Also, IPv4 checksum is not corrected after reassembly.

commit 738ac1eb upstream. Shared skbs must not be modified and this is crucial for broadcast and/or multicast paths where we use it as an optimisation to avoid unnecessary cloning. The function skb_recv_datagram breaks this rule by setting peeked without cloning the skb first. This causes funky races which leads to double-free. This patch fixes this by cloning the skb and replacing the skb in the list when setting skb->peeked. Fixes: a59322be ("[UDP]: Only increment counter on first peek/recv") Reported-by:

commit 7d5cd2ce upstream. If the bond is enslaving a device with different type it will be setup by it, but if after being setup the enslave fails the bond doesn't switch back its type and also keeps pointers to foreign structures that can be long gone. Thus revert back any type changes if the enslave failed and the bond had to change its type. Example: Before patch: $ echo lo > bond0/bonding/slaves -bash: echo: write error: Cannot assign requested address $ ip l sh bond0 20: bond0: <BROADCAST,MULTICAST,MASTER> mtu 1500 qdisc noop state DOWN mode DEFAULT group default link/loopback 16:54:78:34:bd:41 brd 00:00:00:00:00:00 $ echo +eth1 > bond0/bonding/slaves $ ip l sh bond0 20: bond0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000 link/ether 52:54:00:3f:47:69 brd ff:ff:ff:ff:ff:ff (notice the MASTER flag is gone) After patch: $ echo lo > bond0/bonding/slaves -bash: echo: write error: Cannot assign requested address $ ip l sh bond0 21: bond0: <BROADCAST,MULTICAST,MASTER> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000 link/ether 6e:66:94:f6:07:fc brd ff:ff:ff:ff:ff:ff $ echo +eth1 > bond0/bonding/slaves $ ip l sh bond0 21: bond0: <BROADCAST,MULTICAST,MASTER> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000 link/ether 52:54:00:3f:47:69 brd ff:ff:ff:ff:ff:ff Signed-off-by:

commit fd98e941 upstream. Commit 79901317 ("n_tty: Don't flush buffer when closing ldisc"), first merged in kernel release 3.10, caused the following regression in the Gigaset M101 driver: Before that commit, when closing the N_TTY line discipline in preparation to switching to N_GIGASET_M101, receive_room would be reset to a non-zero value by the call to n_tty_flush_buffer() in n_tty's close method. With the removal of that call, receive_room might be left at zero, blocking data reception on the serial line. The present patch fixes that regression by setting receive_room to an appropriate value in the ldisc open method. Fixes: 79901317 ("n_tty: Don't flush buffer when closing ldisc") Signed-off-by:

commit 408806f7 upstream. DTO/DCRC errors were not being informed to the mmc core since commit ae4bf788 ("mmc: omap_hsmmc: consolidate error report handling of HSMMC IRQ"). This commit made sure 'end_trans' is never set on DTO/DCRC errors. This is because after this commit 'host->data' is checked after it has been cleared to NULL by omap_hsmmc_dma_cleanup(). Because 'end_trans' is never set, omap_hsmmc_xfer_done() is never invoked making core layer not to be aware of DTO/DCRC errors. Because of this any command invoked after DTO/DCRC error leads to a hang. Fix this by checking for 'host->data' before it is actually cleared.

commit 34cab6f4 upstream. When we get a read error from the last working device, we don't try to repair it, and don't fail the device. We simple report a read error to the caller. However the current test for 'is this the last working device' is wrong. When there is only one fully working device, it assumes that a non-faulty device is that device. However a spare which is rebuilding would be non-faulty but so not the only working device. So change the test from "!Faulty" to "In_sync". If ->degraded says there is only one fully working device and this device is in_sync, this must be the one. This bug has existed since we allowed read_balance to read from a recovering spare in v3.0 Reported-and-tested-by:

commit 96849170 upstream. This patch fixes a problem in the usbtouchscreen driver for DMC TSC-30 touch screen. Due to a missing delay between the RESET and SET_RATE commands, the touch screen may become unresponsive during system startup or driver loading. According to the DMC documentation, a delay is needed after the RESET command to allow the chip to complete its internal initialization. As this delay is not guaranteed, we had a system where the touch screen occasionally did not send any touch data. There was no other indication of the problem. The patch fixes the problem by adding a 150ms delay between the RESET and SET_RATE commands. Suggested-by:

commit 5fb2c782 upstream. This device automatically switches itself to another mode (0x1405) unless the specific access pattern of Windows is followed in its initial mode. That makes a dirty unmount of the internal storage devices inevitable if they are mounted. So the card reader of such a device should be ignored, lest an unclean removal become inevitable. This replaces an earlier patch that ignored all LUNs of this device. That patch was overly broad. Signed-off-by:

commit 7d8021c9 upstream. This patch fixes a bug introduced by commit 977dcfdc ("USB: OHCI: don't lose track of EDs when a controller dies"). The commit changed ed_state from ED_UNLINK to ED_IDLE too early, before finish_urb() had been called. The user-visible consequence is that the driver occasionally crashes or locks up when an URB is submitted while another URB for the same endpoint is being unlinked. This patch moves the ED state change later, to the right place. The drawback is that now we may unnecessarily execute some instructions multiple times when a controller dies. Since controllers dying is an exceptional occurrence, a little wasted time won't matter. Signed-off-by:

commit fac4271d upstream. When the link is just waken, it's in Resume state, and driver sets PLS to U0. This refers to Phase 1. Phase 2 refers to when the link has completed the transition from Resume state to U0. With the fix of xhci: report U3 when link is in resume state, it also exposes an issue that usb3 roothub and controller can suspend right after phase 1, and this causes a hard hang in controller. To fix the issue, we need to prevent usb3 bus suspend if any port is resuming in phase 1. [merge separate USB2 and USB3 port resume checking to one -Mathias] Signed-off-by:

commit 243292a2 upstream. xhci_hub_report_usb3_link_state() returns pls as U0 when the link is in resume state, and this causes usb core to think the link is in U0 while actually it's in resume state. When usb core transfers control request on the link, it fails with TRB error as the link is not ready for transfer. To fix the issue, report U3 when the link is in resume state, thus usb core knows the link it's not ready for transfer. Signed-off-by:

commit 326124a0 upstream. When resetting a device the number of active TTs may need to be corrected by xhci_update_tt_active_eps, but the number of old active endpoints supplied to it was always zero, so the number of TTs and the bandwidth reserved for them was not updated, and could rise unnecessarily. This affected systems using Intel's Patherpoint chipset, which rely on software bandwidth checking. For example, a Lenovo X230 would lose the ability to use ports on the docking station after enough suspend/resume cycles because the bandwidth calculated would rise with every cycle when a suitable device is attached. The correct number of active endpoints is calculated in the same way as in xhci_reserve_bandwidth. Signed-off-by:

commit 34968106 upstream. virt_dev->num_cached_rings counts on freed ring and is not updated correctly. In xhci_free_or_cache_endpoint_ring() function, the free ring is added into cache and then num_rings_cache is incremented as below: virt_dev->ring_cache[rings_cached] = virt_dev->eps[ep_index].ring; virt_dev->num_rings_cached++; here, free ring pointer is added to a current index and then index is incremented. So current index always points to empty location in the ring cache. For getting available free ring, current index should be decremented first and then corresponding ring buffer value should be taken from ring cache. But In function xhci_endpoint_init(), the num_rings_cached index is accessed before decrement. virt_dev->eps[ep_index].new_ring = virt_dev->ring_cache[virt_dev->num_rings_cached]; virt_dev->ring_cache[virt_dev->num_rings_cached] = NULL; virt_dev->num_rings_cached--; This is bug in manipulating the index of ring cache. And it should be as below: virt_dev->num_rings_cached--; virt_dev->eps[ep_index].new_ring = virt_dev->ring_cache[virt_dev->num_rings_cached]; virt_dev->ring_cache[virt_dev->num_rings_cached] = NULL; Signed-off-by:

commit aebda618 upstream. This fixes an issue introduced in commit b23c8439 (usb: dwc3: gadget: fix DEPSTARTCFG for non-EP0 EPs) that made sure we would only use DEPSTARTCFG once per SetConfig. The trick is that we should use one DEPSTARTCFG per SetConfig *OR* SetInterface. SetInterface was completely missed from the original patch. This problem became aparent after commit 76e838c9 (usb: dwc3: gadget: return error if command sent to DEPCMD register fails) added checking of the return status of device endpoint commands. 'Set Endpoint Transfer Resource' command was caught failing occasionally. This is because the Transfer Resource Index was not getting reset during a SET_INTERFACE request. Finally, to fix the issue, was we have to do is make sure that our start_config_issued flag gets reset whenever we receive a SetInterface request. To verify the problem (and its fix), all we have to do is run test 9 from testusb with 'testusb -t 9 -s 2048 -a -c 5000'. Tested-by:

But current i915 code isn't doing that any more, and no one else really uses reset on resume. So instead just keep the old state around.
