commit b0494532 upstream. This commit does two things. First, if there are any homeless lingering requests, we now request a new osdmap even if the osdmap that is being processed brought no changes, i.e. if a given lingering request turned homeless in one of the previous epochs and remained homeless in the current epoch. Not doing so leaves us with a stale osdmap and as a result we may miss our window for reestablishing the watch and lose notifies. MON=1 OSD=1: # cat linger-needmap.sh #!/bin/bash rbd create --size 1 test DEV=$(rbd map test) ceph osd out 0 rbd map dne/dne # obtain a new osdmap as a side effect (!) sleep 1 ceph osd in 0 rbd resize --size 2 test # rbd info test | grep size -> 2M # blockdev --getsize $DEV -> 1M N.B.: Not obtaining a new osdmap in between "osd out" and "osd in" above is enough to make it miss that resize notify, but that is a bug^Wlimitation of ceph watch/notify v1. Second, homeless lingering requests are now kicked just like those lingering requests whose mapping has changed. This is mainly to recognize that a homeless lingering request makes no sense and to preserve the invariant that a registered lingering request is not sitting on any of r_req_lru_item lists. This spares us a WARN_ON, which commit ba9d114e ("libceph: clear r_req_lru_item in __unregister_linger_request()") tried to fix the _wrong_ way. Signed-off-by:

commit 3c0213d1 upstream. When the v3 hardware sees more than one finger, it uses the semi-mt protocol to report the touches. However, it currently works when num_fingers is 0, 1 or 2, but when it is 3 and above, it sends only 1 finger as if num_fingers was 1.

commit 96c1d058 upstream. BugLink: http://bugs.launchpad.net/bugs/1463584 Hyper-V allows a guest to notify the Hyper-V host that a panic condition occured. This notification can include up to five 64 bit values. These 64 bit values are written into crash MSRs. Once the data has been written into the crash MSRs, the host is then notified by writing into a Crash Control MSR. On the Hyper-V host, the panic notification data is captured in the Windows Event log as a 18590 event. Crash MSRs are defined in appendix H of the Hypervisor Top Level Functional Specification. At the time of this patch, v4.0 is the current functional spec.

ARM: net: delegate filter to kernel interpreter when imm_offset() return value can't fit into 12bits. commit 0b59d880 upstream. The ARM JIT code emits "ldr rX, [pc, #offset]" to access the literal pool. #offset maximum value is 4095 and if the generated code is too large, the #offset value can overflow and not point to the expected slot in the literal pool. Additionally, when overflow occurs, bits of the overflow can end up changing the destination register of the ldr instruction. Fix that by detecting the overflow in imm_offset() and setting a flag that is checked for each BPF instructions converted in build_body(). As of now it can only be detected in the second pass. As a result the second build_body() call can now fail, so add the corresponding cleanup code in that case. Using multiple literal pools in the JITed code is going to require lots of intrusive changes to the JIT code (which would better be done as a feature instead of fix), just delegating to the kernel BPF interpreter in that case is a more straight forward, minimal fix and easy to backport.

commit b0dc2b9b upstream. NUMA balancing is meant to be disabled by default on UMA machines but the check is using nr_node_ids (highest node) instead of num_online_nodes (online nodes). The consequences are that a UMA machine with a node ID of 1 or higher will enable NUMA balancing. This will incur useless overhead due to minor faults with the impact depending on the workload. These are the impact on the stats when running a kernel build on a single node machine whose node ID happened to be 1: vanilla patched NUMA base PTE updates 5113158 0 NUMA huge PMD updates 643 0 NUMA page range updates 5442374 0 NUMA hint faults 2109622 0 NUMA hint local faults 2109622 0 NUMA hint local percent 100 100 NUMA pages migrated 0 0 Signed-off-by:

commit e531d0bc upstream. The journal revoke block recovery code does not check r_count for sanity, which means that an evil value of r_count could result in the kernel reading off the end of the revoke table and into whatever garbage lies beyond. This could crash the kernel, so fix that. However, in testing this fix, I discovered that the code to write out the revoke tables also was not correctly checking to see if the block was full -- the current offset check is fine so long as the revoke table space size is a multiple of the record size, but this is not true when either journal_csum_v[23] are set.

commit 9d506594 upstream. Currently when journal restart fails, we'll have the h_transaction of the handle set to NULL to indicate that the handle has been effectively aborted. We handle this situation quietly in the jbd2_journal_stop() and just free the handle and exit because everything else has been done before we attempted (and failed) to restart the journal. Unfortunately there are a number of problems with that approach introduced with commit 41a5b913 "jbd2: invalidate handle if jbd2_journal_restart() fails" First of all in ext4 jbd2_journal_stop() will be called through __ext4_journal_stop() where we would try to get a hold of the superblock by dereferencing h_transaction which in this case would lead to NULL pointer dereference and crash. In addition we're going to free the handle regardless of the refcount which is bad as well, because others up the call chain will still reference the handle so we might potentially reference already freed memory. Moreover it's expected that we'll get aborted handle as well as detached handle in some of the journalling function as the error propagates up the stack, so it's unnecessary to call WARN_ON every time we get detached handle. And finally we might leak some memory by forgetting to free reserved handle in jbd2_journal_stop() in the case where handle was detached from the transaction (h_transaction is NULL). Fix the NULL pointer dereference in __ext4_journal_stop() by just calling jbd2_journal_stop() quietly as suggested by Jan Kara. Also fix the potential memory leak in jbd2_journal_stop() and use proper handle refcounting before we attempt to free it to avoid use-after-free issues. And finally remove all WARN_ON(!transaction) from the code so that we do not get random traces when something goes wrong because when journal restart fails we will get to some of those functions.

commit 5c1ac56b upstream. In function dmi_present(), dmi_walk_early() calls dmi_table(), which calls dmi_decode(), which ultimately calls dmi_save_uuid(). This last function makes a decision based on the value of global variable dmi_ver. The problem is that this variable is set right _after_ dmi_walk_early() returns. So dmi_save_uuid() always sees dmi_ver == 0 regardless of the actual version implemented. This causes /sys/class/dmi/id/product_uuid to always use the old ordering even on systems implementing DMI/SMBIOS 2.6 or later, which should use the new ordering. This is broken since kernel v3.8 for legacy DMI implementations and since kernel v3.10 for SMBIOS 2 implementations. SMBIOS 3 implementations with the 64-bit entry point are not affected. The first breakage does not matter much as in practice legacy DMI implementations are always for versions older than 2.6, which is when the UUID ordering changed. The second breakage is more problematic as it affects the vast majority of x86 systems manufactured since 2009. Signed-off-by:

commit 18cc2f4c upstream. Our event ring consists of only one segment, and we risk filling the event ring in case we get isoc transfers with short intervals such as webcams that fill a TD every microframe (125us) With 64 TRB segment size one usb camera could fill the event ring in 8ms. A setup with several cameras and other devices can fill up the event ring as it is shared between all devices. This has occurred when uvcvideo queues 5 * 32TD URBs which then get cancelled when the video mode changes. The cancelled URBs are returned in the xhci interrupt context and blocks the interrupt handler from handling the new events. A full event ring will block xhci from scheduling traffic and affect all devices conneted to the xhci, will see errors such as Missed Service Intervals for isoc devices, and and Split transaction errors for LS/FS interrupt devices. Increasing the TRB_PER_SEGMENT will also increase the default endpoint ring size, which is welcome as for most isoc transfer we had to dynamically expand the endpoint ring anyway to be able to queue the 5 * 32TDs uvcvideo queues. The default size used to be 64 TRBs per segment Signed-off-by:

commit d104d015 upstream. Isoc TDs usually consist of one TRB, sometimes two. When all goes well we receive only one success event for a TD, and move the dequeue pointer to the next TD. This fails if the TD consists of two TRBs and we get a transfer error on the first TRB, we will then see two events for that TD. Fix this by making sure the event we get is for the last TRB in that TD before moving the dequeue pointer to the next TD. This will resolve some of the uvc and dvb issues with the "ERROR Transfer event TRB DMA ptr not part of current TD" error message Signed-off-by:

commit b9a5e5e1 upstream. Since acpi_reserve_resources() is defined as a device_initcall(), there's no guarantee that it will be executed in the right order with respect to the rest of the ACPI initialization code. On some systems this leads to breakage if, for example, the address range that should be reserved for the ACPI fixed registers is given to the PCI host bridge instead if the race is won by the wrong code path. Fix this by turning acpi_reserve_resources() into a void function and calling it directly from within the ACPI initialization sequence. Reported-and-tested-by:

commit 82ee3aeb upstream. Samsung has just released a portable USB3 SSD, coming in a very small and nice form factor. It's USB ID is 04e8:8001, which unfortunately is already used by the Palm Visor driver for the Samsung I330 phone cradle. Having pl2303 or visor pick up this device ID results in conflicts with the usb-storage driver, which handles the newly released portable USB3 SSD. To work around this conflict, I've dug up a mailing list post [1] from a long time ago, in which a user posts the full USB descriptor information. The most specific value in this appears to be the interface class, which has value 255 (0xff). Since usb-storage requires an interface class of 0x8, I believe it's correct to disambiguate the two devices by matching on 0xff inside visor.
