commit ae4bedf0 upstream. Newer elantech touchpads are not recognized by the current driver, since it fails to detect their firmware version number. This prevents more advanced touchpad features from being usable such as two-finger scrolling. This patch allows newer touchpads to be detected and be fully functional. Tested on Sony Vaio SVF13N17PXB. Signed-off-by:

commit 9cb80b96 upstream. Added detection for newer Elantech touchpads, so that kernel doesn't fall-back to default PS/2 driver. Supports touchpads released after ~August 2013.

commit 9eebed7d upstream. * Fix version recognition in elantech_set_properties The new hardware reports itself as v7 but the packets' structure is unaltered. * Fix packet type recognition in elantech_packet_check_v4 The bitmask used for v6 is too wide, only the last three bits of the third byte in a packet (packet[3] & 0x03) are actually used to distinguish between packet types. Starting from v7, additional information (to be interpreted) is stored in the remaining bits (packets[3] & 0x1c). In addition, the value stored in (packet[0] & 0x0c) is no longer a constant but contains additional information yet to be deciphered. This change should be backwards compatible with v6 hardware.

commit ea114fc2 upstream. The driver worked around an error in the MAYA44 USB(+)'s mixer unit descriptor by aborting before parsing the missing field. However, aborting parsing too early prevented parsing of the other units connected to this unit, so the capture mixer controls would be missing. Fix this by moving the check for this descriptor error after the parsing of the unit's input pins. Reported-by:

commit 161f873b upstream. We used to read file_handle twice. Once to get the amount of extra bytes, and once to fetch the entire structure. This may be problematic since we do size verifications only after the first read, so if the number of extra bytes changes in userspace between the first and second calls, we'll have an incoherent view of file_handle. Instead, read the constant size once, and copy that over to the final structure without having to re-read it again. Signed-off-by:

commit 3f7352bf upstream. x86 has variable length encoding. x86 JIT compiler is trying to pick the shortest encoding for given bpf instruction. While doing so the jump targets are changing, so JIT is doing multiple passes over the program. Typical program needs 3 passes. Some very short programs converge with 2 passes. Large programs may need 4 or 5. But specially crafted bpf programs may hit the pass limit and if the program converges on the last iteration the JIT compiler will be producing an image full of 'int 3' insns. Fix this corner case by doing final iteration over bpf program. Fixes: 0a14842f ("net: filter: Just In Time compiler for x86-64") Reported-by:

commit 47cc84ce upstream. When more than a multicast address is present in a MLDv2 report, all but the first address is ignored, because the code breaks out of the loop if there has not been an error adding that address. This has caused failures when two guests connected through the bridge tried to communicate using IPv6. Neighbor discoveries would not be transmitted to the other guest when both used a link-local address and a static address. This only happens when there is a MLDv2 querier in the network. The fix will only break out of the loop when there is a failure adding a multicast address.

commit 77bb3dfd upstream. A non-percpu VIRQ (e.g., VIRQ_CONSOLE) may be freed on a different VCPU than it is bound to. This can result in a race between handle_percpu_irq() and removing the action in __free_irq() because handle_percpu_irq() does not take desc->lock. The interrupt handler sees a NULL action and oopses. Only use the percpu chip/handler for per-CPU VIRQs (like VIRQ_TIMER). # cat /proc/interrupts | grep virq 40: 87246 0 xen-percpu-virq timer0 44: 0 0 xen-percpu-virq debug0 47: 0 20995 xen-percpu-virq timer1 51: 0 0 xen-percpu-virq debug1 69: 0 0 xen-dyn-virq xen-pcpu 74: 0 0 xen-dyn-virq mce 75: 29 0 xen-dyn-virq hvc_console 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 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 79bae42d upstream. Move the calls to memcpy_fromio() up into the loop in dmi_scan_machine(), and move the signature checks back down into dmi_decode(). We need to check at 16-byte intervals but keep a 32-byte buffer for an SMBIOS entry, so shift the buffer after each iteration. Merge smbios_present() into dmi_present(), so we look for an SMBIOS signature at the beginning of the given buffer and then for a DMI signature at an offset of 16 bytes.

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 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:
