commit 1965f66e upstream. For bridges with "secondary > subordinate", i.e., invalid bus number apertures, we don't enumerate anything behind the bridge unless the user specified "pci=assign-busses". This patch makes us automatically try to reassign the downstream bus numbers in this case (just for that bridge, not for all bridges as "pci=assign-busses" does). We don't discover all the devices on the Intel DP43BF motherboard without this change (or "pci=assign-busses") because its BIOS configures a bridge as: pci 0000:00:1e.0: PCI bridge to [bus 20-08] (subtractive decode) [bhelgaas: changelog, change message to dev_info] Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=18412 Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=625754Reported-by:

commit 3aa62497 upstream. Currently, when try_to_grab_pending() grabs a delayed work item, it leaves its linked work items alone on the delayed_works. The linked work items are always NO_COLOR and will cause future cwq_activate_first_delayed() increase cwq->nr_active incorrectly, and may cause the whole cwq to stall. For example, state: cwq->max_active = 1, cwq->nr_active = 1 one work in cwq->pool, many in cwq->delayed_works. step1: try_to_grab_pending() removes a work item from delayed_works but leaves its NO_COLOR linked work items on it. step2: Later on, cwq_activate_first_delayed() activates the linked work item increasing ->nr_active. step3: cwq->nr_active = 1, but all activated work items of the cwq are NO_COLOR. When they finish, cwq->nr_active will not be decreased due to NO_COLOR, and no further work items will be activated from cwq->delayed_works. the cwq stalls. Fix it by ensuring the target work item is activated before stealing PENDING in try_to_grab_pending(). This ensures that all the linked work items are activated without incorrectly bumping cwq->nr_active. tj: Updated comment and description. Signed-off-by:

commit 2e12bc29 upstream. domain_update_iommu_coherency() currently defaults to setting domains as coherent when the domain is not attached to any iommus. This allows for a window in domain_context_mapping_one() where such a domain can update context entries non-coherently, and only after update the domain capability to clear iommu_coherency. This can be seen using KVM device assignment on VT-d systems that do not support coherency in the ecap register. When a device is added to a guest, a domain is created (iommu_coherency = 0), the device is attached, and ranges are mapped. If we then hot unplug the device, the coherency is updated and set to the default (1) since no iommus are attached to the domain. A subsequent attach of a device makes use of the same dmar domain (now marked coherent) updates context entries with coherency enabled, and only disables coherency as the last step in the process. To fix this, switch domain_update_iommu_coherency() to use the safer, non-coherent default for domains not attached to iommus. Signed-off-by:

commit feadf7c0 upstream. The EEH core is talking with the PCI device driver to determine the action (purely reset, or PCI device removal).

commit 37bb7899 upstream. This patch fixes error cases within target_core_init_configfs() to properly set ret = -ENOMEM before jumping to the out_global exception path. This was originally discovered with the following Coccinelle semantic match information: Convert a nonnegative error return code to a negative one, as returned elsewhere in the function. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> ( if@p1 (\(ret < 0\|ret != 0\)) { ... return ret; } | ret@p1 = 0 ) ... when != ret = e1 when != &ret *if(...) { ... when != ret = e2 when forall return ret; } // </smpl> Signed-off-by:

commit 40fe4f89 upstream. softsynth_read() reads a character at a time from the init string; when it finds the null terminator it sets the initialized flag but then repeats the last character. Additionally, if the read() buffer is not big enough for the init string, the next read() will start reading from the beginning again. So the caller may never progress to reading anything else. Replace the simple initialized flag with the current position in the init string, carried over between calls. Switch to reading real data once this reaches the null terminator. (This assumes that the length of the init string can't change, which seems to be the case. Really, the string and position belong together in a per-file private struct.) Tested-by:

If a newly registered device is opened quickly enough, we may enable interrupts and try to use ite_dev::rdev before it has been initialised.

commit 21e89afd upstream. It turns out Smart Array logical drives do not support target reset and when the target reset fails, the logical drive will be taken off line. Symptoms look like this: hpsa 0000:03:00.0: Abort request on C1:B0:T0:L0 hpsa 0000:03:00.0: resetting device 1:0:0:0 hpsa 0000:03:00.0: cp ffff880037c56000 is reported invalid (probably means target device no longer present) hpsa 0000:03:00.0: resetting device failed. sd 1:0:0:0: Device offlined - not ready after error recovery sd 1:0:0:0: rejecting I/O to offline device EXT3-fs error (device sdb1): read_block_bitmap: LUN reset is supported though, and is what we should be using. Target reset is also disruptive in shared SAS situations, for example, an external MSA1210m which does support target reset attached to Smart Arrays in multiple hosts -- a target reset from one host is disruptive to other hosts as all LUNs on the target will be reset and will abort all outstanding i/os back to all the attached hosts. So we should use LUN reset, not target reset. Tested this with Smart Array logical drives and with tape drives. Not sure how this bug survived since 2009, except it must be very rare for a Smart Array to require more than 30s to complete a request. Signed-off-by:

commit b92cc66c upstream. Software have to abort command ring and cancel command when a command is failed or hang. Otherwise, the command ring will hang up and can't handle the others. An example of a command that may hang is the Address Device Command, because waiting for a SET_ADDRESS request to be acknowledged by a USB device is outside of the xHC's ability to control. To cancel a command, software will initialize a command descriptor for the cancel command, and add it into a cancel_cmd_list of xhci. Sarah: Fixed missing newline on "Have the command ring been stopped?" debugging statement. This patch should be backported to kernels as old as 3.0, that contain the commit 7ed603ec "xhci: Add an assertion to check for virt_dev=0 bug."

commit c181bc5b upstream. Adding cmd_ring_state for command ring. It helps to verify the current command ring state for controlling the command ring operations. This patch should be backported to kernels as old as 3.0. The commit 7ed603ec "xhci: Add an assertion to check for virt_dev=0 bug." papers over the NULL pointer dereference that I now believe is related to a timed out Set Address command. This (and the four patches that follow it) contain the real fix that also allows VIA USB 3.0 hubs to consistently re-enumerate during the plug/unplug stress tests. Signed-off-by:

commit 5af98bb0 upstream. Eric Fu reports a problem with his VIA host controller fetching a zeroed event ring pointer on resume from suspend. The host should have been halted, but we can't be sure because that code ignores the return value from xhci_halt(). Print a warning when the host controller refuses to halt within XHCI_MAX_HALT_USEC (currently 16 seconds). (Update: it turns out that the VIA host controller is reporting a halted state when it fetches the zeroed event ring pointer. However, we still need this warning for other host controllers.)

commit 947ca185 upstream. DEADLOCK will be report while running a kernel with NUMA and LOCKDEP enabled, the process of this fake report is: kmem_cache_free() //free obj in cachep -> cache_free_alien() //acquire cachep's l3 alien lock -> __drain_alien_cache() -> free_block() -> slab_destroy() -> kmem_cache_free() //free slab in cachep->slabp_cache -> cache_free_alien() //acquire cachep->slabp_cache's l3 alien lock Since the cachep and cachep->slabp_cache's l3 alien are in the same lock class, fake report generated. This should not happen since we already have init_lock_keys() which will reassign the lock class for both l3 list and l3 alien. However, init_lock_keys() was invoked at a wrong position which is before we invoke enable_cpucache() on each cache. Since until set slab_state to be FULL, we won't invoke enable_cpucache() on caches to build their l3 alien while creating them, so although we invoked init_lock_keys(), the l3 alien lock class won't change since we don't have them until invoked enable_cpucache() later. This patch will invoke init_lock_keys() after we done enable_cpucache() instead of before to avoid the fake DEADLOCK report.

commit 10c6c383 upstream. The design of uplink flow control in the mux driver is that for constipated channels data will backup into the per-channel fifos, and any messages that make it to the outbound message queue will still go out. Code was added to also stop messages that were in the outbound queue but this requires filtering through all the messages on the queue for stopped dlcis and changes some of the mux logic unneccessarily. The message fiiltering was removed to be in line w/ the original design as the message filtering does not provide any solution. Extra debug messages used during investigation were also removed.

This patch implement 5.8.1 in MUX level, it make sure DLC0 is the first channel to be setup.

commit 959d1af8 upstream. WORK_STRUCT_PENDING is used to claim ownership of a work item and process_one_work() releases it before starting execution. When someone else grabs PENDING, all pre-release updates to the work item should be visible and all updates made by the new owner should happen afterwards. Grabbing PENDING uses test_and_set_bit() and thus has a full barrier; however, clearing doesn't have a matching wmb. Given the preceding spin_unlock and use of clear_bit, I don't believe this can be a problem on an actual machine and there hasn't been any related report but it still is theretically possible for clear_pending to permeate upwards and happen before work->entry update. Add an explicit smp_wmb() before work_clear_pending(). Signed-off-by:

[ Upstream commit cf9ecf4b ] On the earliest TSO capable devices, TSO was accomplished through firmware. The TSO cannot coexist with ASF management firmware though. The tg3 driver determines whether or not ASF is enabled by calling tg3_get_eeprom_hw_cfg(), which checks a particular bit of NIC memory. Commit dabc5c67, entitled "tg3: Move TSO_CAPABLE assignment", accidentally moved the code that determines TSO capabilities earlier than the call to tg3_get_eeprom_hw_cfg(). As a consequence, the driver was attempting to determine TSO capabilities before it had all the data it needed to make the decision. This patch fixes the problem by revisiting and reevaluating the decision after tg3_get_eeprom_hw_cfg() is called. Signed-off-by:
