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:

Alan Stern authored
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:

It's causing piles of issues since we've stopped forcing full detect cycles in the sysfs interfaces with commit c484f02d Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Fri Mar 6 12:36:42 2015 +0000 drm: Lighten sysfs connector 'status' The original justification for this was that the hpd handlers could use the unknown state as a hint to force a full detection. 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.

commit e9e4dd32 upstream. commit 381c759d ("ipv4: Avoid crashing in ip_error") fixes a problem where processed packet comes from device with destroyed inetdev (dev->ip_ptr). This is not expected because inetdev_destroy is called in NETDEV_UNREGISTER phase and packets should not be processed after dev_close_many() and synchronize_net(). Above fix is still required because inetdev_destroy can be called for other reasons. But it shows the real problem: backlog can keep packets for long time and they do not hold reference to device. Such packets are then delivered to upper levels at the same time when device is unregistered. Calling flush_backlog after NETDEV_UNREGISTER_FINAL still accounts all packets from backlog but before that some packets continue to be delivered to upper levels long after the synchronize_net call which is supposed to wait the last ones. Also, as Eric pointed out, processed packets, mostly from other devices, can continue to add new packets to backlog. Fix the problem by moving flush_backlog early, after the device driver is stopped and before the synchronize_net() call. Then use netif_running check to make sure we do not add more packets to backlog. We have to do it in enqueue_to_backlog context when the local IRQ is disabled. As result, after the flush_backlog and synchronize_net sequence all packets should be accounted. Thanks to Eric W. Biederman for the test script and his valuable feedback! Reported-by:

commit f1158b74 upstream. Since commit b0e9a30d ("bridge: Add vlan id to multicast groups") there's a check in br_ip_equal() for a matching vlan id, but the mdb functions were not modified to use (or at least zero it) so when an entry was added it would have a garbage vlan id (from the local br_ip variable in __br_mdb_add/del) and this would prevent it from being matched and also deleted. So zero out the whole local ip var to protect ourselves from future changes and also to fix the current bug, since there's no vlan id support in the mdb uapi - use always vlan id 0.

commit 75a06189 upstream. The resend mechanism happily calls the interrupt handler of interrupts which are marked IRQ_NESTED_THREAD from softirq context. This can result in crashes because the interrupt handler is not the proper way to invoke the device handlers. They must be invoked via handle_nested_irq. Prevent the resend even if the interrupt has no valid parent irq set. Its better to have a lost interrupt than a crashing machine. Reported-by:

When the GPU is powered up again, radeon_gart_table_vram_pin flushes the TLB after setting rdev->gart.ptr to non-NULL. Fixes panic on powering off R7xx GPUs.
