2014-07-02target: Explicitly clear ramdisk_mcp backend pagesNicholas A. Bellinger
[Note that a different patch to address the same issue went in during v3.15-rc1 (commit 4442dc8a), but includes a bunch of other changes that don't strictly apply to fixing the bug] This patch changes rd_allocate_sgl_table() to explicitly clear ramdisk_mcp backend memory pages by passing __GFP_ZERO into alloc_pages(). This addresses a potential security issue where reading from a ramdisk_mcp could return sensitive information, and follows what >= v3.15 does to explicitly clear ramdisk_mcp memory at backend device initialization time.

2014-07-02target: Report correct response length for some commandsRoland Dreier
commit 2426bd456a61407388b6e61fc5f98dbcbebc50e2 upstream. When an initiator sends an allocation length bigger than what its command consumes, the target should only return the actual response data and set the residual length to the unused part of the allocation length. Add a helper function that command handlers (INQUIRY, READ CAPACITY, etc) can use to do this correctly, and use this code to get the correct residual for commands that don't use the full initiator allocation in the handlers for READ CAPACITY, READ CAPACITY(16), INQUIRY, MODE SENSE and REPORT LUNS.

commit 22c7aaa57e80853b4904a46c18f97db0036a3b97 upstream. In case the transport is iser we should not include the iscsi target info in the sendtargets text response pdu.

2014-07-02iscsi-target: Fix ABORT_TASK + connection reset iscsi_queue_req memory leakNicholas Bellinger
commit bbc050488525e1ab1194c27355f63c66814385b8 upstream. This patch fixes a iscsi_queue_req memory leak when ABORT_TASK response has been queued by TFO->queue_tm_rsp() -> lio_queue_tm_rsp() after a long standing I/O completes, but the connection has already reset and waiting for cleanup to complete in iscsit_release_commands_from_conn() -> transport_generic_free_cmd() -> transport_wait_for_tasks() code. It moves iscsit_free_queue_reqs_for_conn() after the per-connection command list has been released, so that the associated se_cmd tag can be completed + released by target-core before freeing any remaining iscsi_queue_req memory for the connection generated by lio_queue_tm_rsp().

commit a95d6511303b848da45ee27b35018bb58087bdc6 upstream. This patch fixes a bug where multiple waiters on ->t_transport_stop_comp occurs due to a concurrent ABORT_TASK and session reset both invoking transport_wait_for_tasks(), while waiting for the associated se_cmd descriptor backend processing to complete. For this case, complete_all() should be invoked in order to wake up both waiters in core_tmr_abort_task() + transport_generic_free_cmd() process contexts.

commit 88c4015fda6d014392f76d3b1688347950d7a12d upstream. There are 4 RDMA_CM events that all basically mean that the user should teardown the IB connection: - DISCONNECTED - ADDR_CHANGE - DEVICE_REMOVAL - TIMEWAIT_EXIT Only in DISCONNECTED/ADDR_CHANGE it makes sense to call rdma_disconnect (send DREQ/DREP to our initiator). So we keep the same teardown handler for all of them but only indicate calling rdma_disconnect for the relevant events.

2014-07-02Target/iser: Fix hangs in connection teardownSagi Grimberg
commit 9d49f5e284e700576f3b65f1e28dea8539da6661 upstream. In ungraceful teardowns isert close flows seem racy such that isert_wait_conn hangs as RDMA_CM_EVENT_DISCONNECTED never gets invoked (no one called rdma_disconnect). Both graceful and ungraceful teardowns will have rx flush errors (isert posts a batch once connection is established). Once all flush errors are consumed we invoke isert_wait_conn and it will be responsible for calling rdma_disconnect. This way it can be sure that rdma_disconnect was called and it won't wait forever. This patch also removes the logout_posted indicator. either the logout completion was consumed and no problem decrementing the post_send_buf_count, or it was consumed as a flush error. no point of keeping it for isert_wait_conn as there is no danger that isert_conn will be accidentally removed while it is running.

commit 85ac1a1772bb41da895bad83a81f6a62c8f293f6 upstream. Currently stk1160_read_reg() uses a stack-allocated char to get the read control value. This is wrong because usb_control_msg() requires a kmalloc-ed buffer. This commit fixes such issue by kmalloc'ating a 1-byte buffer to receive the read value. While here, let's remove the urb_buf array which was meant for a similar purpose, but never really used.

commit 80cc0fcbdaeaf10d04ba27779a2d7ceb73d2717a upstream. Make sure that needs_remote_wake up is always set when there are open ports. Currently close() would unconditionally set needs_remote_wakeup to 0 even though there might still be open ports. This could lead to blocked input and possibly dropped data on devices that do not support remote wakeup (and which must therefore not be runtime suspended while open).

commit 7fdd26a01eb7b6cb6855ff8f69ef4a720720dfcb upstream. Neither the transfer buffer or the urb itself were released in the resume error path for delayed writes. Also on errors, the remainder of the queue was not even processed, which leads to further urb and buffer leaks. The same error path also failed to balance the outstanding-urb counter, something which results in degraded throughput or completely blocked writes.

commit fb7ad4f93d9f0f7d49beda32f5e7becb94b29a4d upstream. Keep trying to submit urbs rather than bail out on first read-urb submission error, which would also prevent I/O for any further ports from being resumed. Instead keep an error count, for all types of failed submissions, and let USB core know that something went wrong. Also make sure to always clear the suspended flag. Currently a failed read-urb submission would prevent cached writes as well as any subsequent writes from being submitted until next suspend-resume cycle, something which may not even necessarily happen.

2014-07-02matroxfb: perform a dummy read of M_STATUSMikulas Patocka
commit 972754cfaee94d6e25acf94a497bc0a864d91b7e upstream. I had occasional screen corruption with the matrox framebuffer driver and I found out that the reason for the corruption is that the hardware blitter accesses the videoram while it is being written to. The matrox driver has a macro WaitTillIdle() that should wait until the blitter is idle, but it sometimes doesn't work. I added a dummy read mga_inl(M_STATUS) to WaitTillIdle() to fix the problem. The dummy read will flush the write buffer in the PCI chipset, and the next read of M_STATUS will return the hardware status. Since applying this patch, I had no screen corruption at all.

2014-07-02USB: EHCI: avoid BIOS handover on the HASEE E200Alan Stern
commit b0a50e92bda3c4aeb8017d4e6c6e92146ebd5c9b upstream. Leandro Liptak reports that his HASEE E200 computer hangs when we ask the BIOS to hand over control of the EHCI host controller. This definitely sounds like a bug in the BIOS, but at the moment there is no way to fix it. This patch works around the problem by avoiding the handoff whenever the motherboard and BIOS version match those of Leandro's computer.

2014-07-02ARM: OMAP: replace checks for CONFIG_USB_GADGET_OMAPPaul Bolle
commit 77c2f02edbeda9409a7cf3fd66233015820c213a upstream. Commit 193ab2a60700 ("usb: gadget: allow multiple gadgets to be built") apparently required that checks for CONFIG_USB_GADGET_OMAP would be replaced with checks for CONFIG_USB_OMAP. Do so now for the remaining checks for CONFIG_USB_GADGET_OMAP, even though these checks have basically been broken since v3.1. And, since we're touching this code, use the IS_ENABLED() macro, so things will now (hopefully) also work if USB_OMAP is modular.

commit 32b36eeae6a859670d2939a7d6136cb5e9ed64f8 upstream. In usbtest, tests 5 - 8 use the scatter-gather library in usbcore without any sort of timeout. If there's a problem in the gadget or host controller being tested, the test can hang. This patch adds a 10-second timeout to the tests, so that they will fail gracefully with an ETIMEDOUT error instead of hanging.

2014-07-02usb: usbtest: fix unlink write error with pattern 1Huang Rui
commit e4d58f5dcb7d7be45df8def31881ebfae99c75da upstream. TEST 12 and TEST 24 unlinks the URB write request for N times. When host and gadget both initialize pattern 1 (mod 63) data series to transfer, the gadget side will complain the wrong data which is not expected. Because in host side, usbtest doesn't fill the data buffer as mod 63 and this patch fixed it.
