2015-06-08fix: align closely to AOSP.Sumit Semwal
To support Android on a member platform, LMG carry forwarded quiet a few (200+) aosp/android-3.10 patches to linaro-android-3.14-lsk tree when aosp/android-3.14 was not announced. There are few gaps in our forward-ported branch from 3.10->3.14, and how AOSP is maintaining the patches. This consolidated patch help align our tree with AOSP, unless we've added some fixes. Listed below are file-wise changes and rationale behind them: - arch/arm/Kconfig: c0cc1d84: seccomp revert is missing from AOSP, potentially because of cleaner seccomp patches => Align with AOSP. - arch/arm/mm/mmu.c: 97b095e5: "ARM: mm: Split memory banks that span multiple sections when sparsemem is enabled" doesn't seem required anymore, and isn't added to AOSP => Align with AOSP. - arch/arm64/Kconfig: 27aa5398: "arm64: a backwards compatible config option", and 8354fc2d: "arm64: cpuinfo: ARMv7 compatable cpuinfo option" are reverted in AOSP trees => Remove and align with AOSP - arch/arm64/include/asm/debug-monitors.h: Minor differences with AOSP merge v/s ours => Align with AOSP - arch/mips/include/uapi/asm/unistd.h: 598966e MIPS: add seccomp syscall has merge differences between AOSP and ours => Align with AOSP. - drivers/mmc/core/core.c: drivers/mmc/core/host.c: include/linux/mmc/host.h: 2f76feb mmc: core: host: only use wakelock for detect work by Colin Cross: was present in 3.10,and so in fwd-port; Missing from 3.14/3.18; it als introduced a memory leak w/ TI => Align with AOSP by reverting the above commit - drivers/usb/gadget/f_accessory.c: feee075e: "usb: gadget: f_accessory: fix missing NULL pointer check" by Amit Pundir that was being carried in linaro-fixes isn't required anymore due to the AOSP merged fix. => Align with AOSP. - drivers/usb/gadget/u_ether.c: minor code rearrangement during our merge => ALIGN with AOSP. - include/net/bluetooth/hci.h: include/net/bluetooth/hci_core.h: net/bluetooth/hci_conn.c: net/bluetooth/hci_event.c: net/bluetooth/rfcomm/core.c: => BT Patches not in 3.14/3.18; ALIGN with AOSP. - include/net/netfilter/ipv4/nf_reject.h: include/net/netfilter/ipv6/nf_reject.h: net/ipv4/netfilter/Kconfig: net/ipv6/netfilter/Kconfig: 8d83a89758: netfilter: have ip*t REJECT set the sock err when an icmp is to be sent: NOT in 3.14/3.18 => ALIGN with AOSP - include/uapi/asm-generic/unistd.h: 08f6b117d: seccomp: add "seccomp" syscall has merge differences between our merge and AOSP's => ALIGN with AOSP - kernel/irq/pm.c: c2d35c6 irq: pm: Remove unused variable by Dmitry Shmidt => ALIGN with AOSP. - kernel/power/wakelock.c: 11388c8 PM / Sleep: Require CAP_BLOCK_SUSPEND to use wake_lock/wake_unlock by Rafael J.

2015-06-06USB: visor: Match I330 phone more preciselyJason A. Donenfeld
commit 82ee3aeb9295c5fc37fd2ddf20f13ac2b40ec97d 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.

2015-06-06xhci: Solve full event ring by increasing TRBS_PER_SEGMENT to 256Mathias Nyman
commit 18cc2f4cbbaf825a4fedcf2d60fd388d291e0a38 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: Mathias Nyman <mathias.nyman@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2015-06-06xhci: fix isoc endpoint dequeue from advancing too far on transaction errorMathias Nyman
commit d104d0152a97fade389f47635b73a9ccc7295d0b 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: Mathias Nyman <mathias.nyman@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2015-05-13usb: gadget: printer: enqueue printer's response for setup requestAndrzej Pietrasiewicz
commit eb132ccbdec5df46e29c9814adf76075ce83576b upstream. Function-specific setup requests should be handled in such a way, that apart from filling in the data buffer, the requests are also actually enqueued: if function-specific setup is called from composte_setup(), the "usb_ep_queue()" block of code in composite_setup() is skipped. The printer function lacks this part and it results in e.g. get device id requests failing: the host expects some response, the device prepares it but does not equeue it for sending to the host, so the host finally asserts timeout. This patch adds enqueueing the prepared responses.

2015-04-19usb: xhci: apply XHCI_AVOID_BEI quirk to all Intel xHCI controllersLu Baolu
commit 227a4fd801c8a9fa2c4700ab98ec1aec06e3b44d upstream. When a device with an isochronous endpoint is plugged into the Intel xHCI host controller, and the driver submits multiple frames per URB, the xHCI driver will set the Block Event Interrupt (BEI) flag on all but the last TD for the URB. This causes the host controller to place an event on the event ring, but not send an interrupt. When the last TD for the URB completes, BEI is cleared, and we get an interrupt for the whole URB. However, under Intel xHCI host controllers, if the event ring is full of events from transfers with BEI set, an "Event Ring is Full" event will be posted to the last entry of the event ring, but no interrupt is generated. Host will cease all transfer and command executions and wait until software completes handling the pending events in the event ring. That means xHC stops, but event of "event ring is full" is not notified. As the result, the xHC looks like dead to user. This patch is to apply XHCI_AVOID_BEI quirk to Intel xHC devices. And it should be backported to kernels as old as 3.0, that contains the commit 69e848c2090a ("Intel xhci: Support EHCI/xHCI port switching.").

2015-04-19usb: xhci: handle Config Error Change (CEC) in xhci driverLu Baolu
commit 9425183d177aa4a2f09d01a74925124f0778b595 upstream. Linux xHCI driver doesn't report and handle port cofig error change. If Port Configure Error for root hub port occurs, CEC bit in PORTSC would be set by xHC and remains 1. This happends when the root port fails to configure its link partner, e.g. the port fails to exchange port capabilities information using Port Capability LMPs. Then the Port Status Change Events will be blocked until all status change bits(CEC is one of the change bits) are cleared('0') (refer to xHCI spec 4.19.2). Otherwise, the port status change event for this root port will not be generated anymore, then root port would look like dead for user and can't be recovered until a Host Controller Reset(HCRST). This patch is to check CEC bit in PORTSC in xhci_get_port_status() and set a Config Error in the return status if CEC is set. This will cause a ClearPortFeature request, where CEC bit is cleared in xhci_clear_port_change_bit().

2015-03-18xhci: fix reporting of 0-sized URBs in control endpointAleksander Morgado
commit 45ba2154d12fc43b70312198ec47085f10be801a upstream. When a control transfer has a short data stage, the xHCI controller generates two transfer events: a COMP_SHORT_TX event that specifies the untransferred amount, and a COMP_SUCCESS event. But when the data stage is not short, only the COMP_SUCCESS event occurs. Therefore, xhci-hcd must set urb->actual_length to urb->transfer_buffer_length while processing the COMP_SUCCESS event, unless urb->actual_length was set already by a previous COMP_SHORT_TX event. The driver checks this by seeing whether urb->actual_length == 0, but this alone is the wrong test, as it is entirely possible for a short transfer to have an urb->actual_length = 0. This patch changes the xhci driver to rely on a new td->urb_length_set flag, which is set to true when a COMP_SHORT_TX event is received and the URB length updated at that stage. This fixes a bug which affected the HSO plugin, which relies on URBs with urb->actual_length == 0 to halt re-submitting the RX URB in the control endpoint.
