* SCSI: sd: fix crash when UA received on DIF enabled deviceEwan D. Milne2013-08-04
| | | | | | | | | | | | | | | | | | | | | | | | commit 085b513f97d8d799d28491239be4b451bcd8c2c5 upstream. sd_prep_fn will allocate a larger CDB for the command via mempool_alloc for devices using DIF type 2 protection. This CDB was being freed in sd_done, which results in a kernel crash if the command is retried due to a UNIT ATTENTION. This change moves the code to free the larger CDB into sd_unprep_fn instead, which is invoked after the request is complete. It is no longer necessary to call scsi_print_command separately for this case as the ->cmnd will no longer be NULL in the normal code path. Also removed conditional test for DIF type 2 when freeing the larger CDB because the protection_type could have been changed via sysfs while the command was executing. Signed-off-by: Ewan D.

* SCSI: isci: Fix a race condition in the SSP task management pathJeff Skirvin2013-08-04
| | | | | | | | | | | | | | | | | commit 96f15f29038e58e1b0a96483e2b369ff446becf1 upstream. This commit fixes a race condition in the isci driver abort task and SSP device task management path. The race is caused when an I/O termination in the SCU hardware is necessary because of an SSP target timeout condition, and the check of the I/O end state races against the HW-termination-driven end state. The failure of the race meant that no TMF was sent to the device to clean-up the pending I/O.

* ARM: 7722/1: zImage: Convert 32bits memory size and address from ATAG to ↵Gregory CLEMENT2013-08-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 64bits DTB commit faefd550c45d8d314e8f260f21565320355c947f upstream. When CONFIG_ARM_APPENDED_DTB is selected, if the bootloader provides an ATAG_MEM it replaces the memory size and the memory address in the memory node of the device tree. In the case of a system which can handle more than 4GB, the memory node cell size is 4: each data (memory size and memory address) are 64 bits and then use 2 cells. The current code in atags_to_fdt.c made the assumption of a cell size of 2 (one cell for the memory size and one cell for the memory address), this leads to an improper write of the data and ends with a boot hang. This patch writes the memory size and the memory address on the memory node in the device tree depending of the size of the memory node (32 bits or 64 bits). It has been tested in the 2 cases: - with a dtb using skeleton.dtsi - and with a dtb using skeleton64.dtsi Signed-off-by: Gregory CLEMENT <gregory.clement@free-electrons.com> Acked-by: Nicolas Pitre <nico@linaro.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> Cc: Willy Tarreau <w@1wt.eu> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

Commit 18d627113b83 (firewire: prevent dropping of completed iso packet header data) was intended to be an obvious bug fix, but libdc1394 and FlyCap2 depend on the old behaviour by ignoring all returned information and thus not noticing that not all packets have been received yet. The result was that the video frame buffers would be saved before they contained the correct data. Reintroduce the old behaviour for old clients.

* ALSA: hda - Remove NO_PRESENCE bit override for Dell 1420n LaptopTakashi Iwai2013-07-28
| | | | | | | | | | | | | | | | | | | | commit f3e351eef3a7fd1e36a3e18d4f2f069b00deb23c upstream. The quirk for Dell laptops with STAC9228 overrides the pin default config of NID 0x0f to the value with AC_DEFCFG_MISC_NO_PRESENCE bit on. I'm not quite sure why this was done so, but can guess that this was introduced for avoiding this to be muted by another headphone plug. Now, after transition to the generic parser, this workaround rather causes a problem (notably as unexpected speaker mutes) because the pin is seen as if it's always plugged in. Since the generic parser can handle multiple headphone plugging gracefully, we can get rid of this override now.

* hrtimers: Move SMP function call to thread contextThomas Gleixner2013-07-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 5ec2481b7b47a4005bb446d176e5d0257400c77d upstream. smp_call_function_* must not be called from softirq context. But clock_was_set() which calls on_each_cpu() is called from softirq context to implement a delayed clock_was_set() for the timer interrupt handler. Though that almost never gets invoked. A recent change in the resume code uses the softirq based delayed clock_was_set to support Xens resume mechanism. linux-next contains a new warning which warns if smp_call_function_* is called from softirq context which gets triggered by that Xen change. Fix this by moving the delayed clock_was_set() call to a work context.

* lockd: protect nlm_blocked access in nlmsvc_retry_blockedDavid Jeffery2013-07-28
| | | | | | | | | | | | | | | | | | | | | | | | | commit 1c327d962fc420aea046c16215a552710bde8231 upstream. In nlmsvc_retry_blocked, the check that the list is non-empty and acquiring the pointer of the first entry is unprotected by any lock. This allows a rare race condition when there is only one entry on the list. A function such as nlmsvc_grant_callback() can be called, which will temporarily remove the entry from the list. Between the list_empty() and list_entry(),the list may become empty, causing an invalid pointer to be used as an nlm_block, leading to a possible crash. This patch adds the nlm_block_lock around these calls to prevent concurrent use of the nlm_blocked list. This was a regression introduced by f904be9cc77f361d37d71468b13ff3d1a1823dea "lockd: Mostly remove BKL from the server".

This prevents the following breakage from happening (scenario from Zhang Yanmin): Kernel starts shutdown and calls all device driver's shutdown callback. When a driver's shutdown is called, the last wakelock is released and suspend-to-ram starts. However, as some driver's shut down callbacks already shut down devices and disabled runtime pm, the suspend-to-ram calls driver's suspend callback without noticing that device is already off and causes crash.

* ARM: S3C24XX: Add missing clkdev entries for s3c2440 UARTSylwester Nawrocki2013-07-28
| | | | | | | | | | | | | | | | | | | | | | | | | | commit d817468c4b2892b9468e2a0c92116e38a3a61370 upstream. This patch restores serial port operation which has been broken since commit 60e93575476f ("serial: samsung: enable clock before clearing pending interrupts during init") That commit only uncovered the real issue which was missing clkdev entries for the "uart" clocks on S3C2440. It went unnoticed so far because return value of clk API calls were not being checked at all in the samsung serial port driver. This patch should be backported to at least 3.10 stable kernel, since the serial port has not been working on s3c2440 since 3.10-rc5.

With some enclosures when LUN 0 is not created but LUN 1 or LUN X is created then SCSI scan procedure calls target_alloc, slave_alloc call back functions for LUN 0 and slave_destory() for same LUN 0. In these kind of cases within slave_destroy, pointer to scsi_target in _sas_device structure is set to NULL, following which when slave_alloc for LUN 1 is called then starget would not be set properly for this LUN. So, scsi_target pointer pointing to NULL value would lead to a crash later in the discovery procedure. To solve this issue set the sas_device's scsi_target pointer to scsi_device's scsi_target if it is NULL earlier in slave_alloc callback function.

| | | | | | | | | | | | | | | | | | | | commit faa5673617656ee58369a3cfe4a312cfcdc59c81 upstream. The journal replay code starts by finding something that looks like a valid journal entry, then it does a binary search over the unchecked region of the journal for the journal entries with the highest sequence numbers. Trouble is, the logic was wrong - journal_read_bucket() returns true if it found journal entries we need, but if the range of journal entries we're looking for loops around the end of the journal - in that case journal_read_bucket() could return true when it hadn't found the highest sequence number we'd seen yet, and in that case the binary search did the wrong thing.

Part of the job of garbage collection is to add up however many sectors of live data it finds in each bucket, but that doesn't work very well if it doesn't reset GC_SECTORS_USED() when it starts. Whoops. This wouldn't have broken anything horribly, but allocation tries to preferentially reclaim buckets that are mostly empty and that's not gonna work with an incorrect GC_SECTORS_USED() value.

In the far-too-complicated closure code - closures can have destructors, for probably dubious reasons; they get run after the closure is no longer waiting on anything but before dropping the parent ref, intended just for freeing whatever memory the closure is embedded in. Trouble is, when remaining goes to 0 and we've got nothing more to run - we also have to unlock the closure, setting remaining to -1. If there's a destructor, that unlock isn't doing anything - nobody could be trying to lock it if we're about to free it - but if the unlock _is needed... that check for a destructor was racy. Argh.
