2012-03-14AppArmor: Move path failure information into aa_get_name and renameJohn Johansen
Move the path name lookup failure messages into the main path name lookup routine, as the information is useful in more than just aa_path_perm. Also rename aa_get_name to aa_path_name as it is not getting a reference counted object with a corresponding put fn.

2012-03-14AppArmor: Fix oops in policy unpack auditingJohn Johansen
Post unpacking of policy a verification pass is made on x transition indexes. When this fails a call to audit_iface is made resulting in an oops, because audit_iface is expecting a valid buffer position but since the failure comes from post unpack verification there is none. Make the position argument optional so that audit_iface can be called from post unpack verification. Signed-off-by: John Johansen <john.johansen@canonical.com>
2012-03-14AppArmor: Fix error returned when a path lookup is disconnectedJohn Johansen
The returning of -ESATLE when a path lookup fails as disconnected is wrong. Since AppArmor is rejecting the access return -EACCES instead. This also fixes a bug in complain (learning) mode where disconnected paths are denied because -ESTALE errors are not ignored causing failures that can change application behavior.

2012-03-14genirq: Flush the irq thread on synchronizationIdo Yariv
The current implementation does not always flush the threaded handler when disabling the irq. In case the irq handler was called, but the threaded handler hasn't started running yet, the interrupt will be flagged as pending, and the handler will not run. This implementation has some issues: First, if the interrupt is a wake source and flagged as pending, the system will not be able to suspend. Second, when quickly disabling and re-enabling the irq, the threaded handler might continue to run after the irq is re-enabled without the irq handler being called first. This might be an unexpected behavior. In addition, it might be counter-intuitive that the threaded handler will not be called even though the irq handler was called and returned IRQ_WAKE_THREAD. Fix this by always waiting for the threaded handler to complete in synchronize_irq().

2012-03-14padata: Fix race on sequence number wrapSteffen Klassert
When padata_do_parallel() is called from multiple cpus for the same padata instance, we can get object reordering on sequence number wrap because testing for sequence number wrap and reseting the sequence number must happen atomically but is implemented with two atomic operations. This patch fixes this by converting the sequence number from atomic_t to an unsigned int and protect the access with a spin_lock. As a side effect, we get rid of the sequence number wrap handling because the seqence number wraps back to null now without the need to do anything.

2012-03-14crypto: camellia - add assembler implementation for x86_64Jussi Kivilinna
Patch adds x86_64 assembler implementation of Camellia block cipher. Two set of functions are provided. First set is regular 'one-block at time' encrypt/decrypt functions. Second is 'two-block at time' functions that gain performance increase on out-of-order CPUs. Performance of 2-way functions should be equal to 1-way functions with in-order CPUs. Patch has been tested with tcrypt and automated filesystem tests.

2012-03-13iscsi-target: Fix reservation conflict -EBUSY response handling bugNicholas Bellinger
This patch addresses a iscsi-target specific bug related to reservation conflict handling in iscsit_handle_scsi_cmd() that has been causing reservation conflicts to complete and not fail as expected due to incorrect errno checking. The problem occured with the change to return -EBUSY from transport_generic_cmd_sequencer() -> transport_generic_allocate_tasks() failures, that broke iscsit_handle_scsi_cmd() checking for -EINVAL in order to invoke a non GOOD status response. This was manifesting itself as data corruption with legacy SPC-2 reservations, but also effects iscsi-target LUNs with SPC-3 persistent reservations. This bug was originally introduced in lio-core commit: commit 03e98c9eb916f3f0868c1dc344dde2a60287ff72 Author: Nicholas Bellinger <nab@linux-iscsi.org> Date: Fri Nov 4 02:36:16 2011 -0700 target: Address legacy PYX_TRANSPORT_* return code breakage Reported-by: Martin Svec <martin.svec@zoner.cz> Cc: Martin Svec <martin.svec@zoner.cz> Cc: Christoph Hellwig <hch@lst.de> Cc: stable@vger.kernel.org Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>

Also explictly set cmd->scsi_status = SAM_STAT_RESERVATION_CONFLICT during the early non reservation holder failure from pr_ops->t10_seq_non_holder() check in transport_generic_cmd_sequencer() for fabrics that already expect it to be set.

2012-03-13regulator: tps65910: Provide settling time for enabling railsLaxman Dewangan
There is settling time for each rails when it is switched to ON. Implementing enable time for returning proper settling time of regulator rails when it is enabled. Filling the on-time for each rail as per tps65910/tps65911 datasheets. Signed-off-by: Laxman Dewangan <ldewangan@nvidia.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

2012-03-13regulator: tps65912: Use simple equations to get register addressAxel Lin
The address of ctrl and sel registers can be calculated by simple equations. This patch simplifies the implementation in tps65912_get_ctrl_register and implements tps65912_get_sel_register to replace tps65912_get_dcdc_sel_register and tps65912_get_ldo_sel_register.

2012-03-13usb: Don't make USB_ARCH_HAS_{XHCI,OHCI,EHCI} depend on USB_SUPPORT.David Daney
The fact that an architecture/board has XHCI, OHCI or EHCI does not depend on the fact that the kernel is configured with USB_SUPPORT. Make the Kconfig reflect this fact thus avoiding ugly messages like: warning: (MIPS_ALCHEMY && CAVIUM_OCTEON_REFERENCE_BOARD && SOC_AR71XX && SOC_AR724X && SOC_AR913X && SOC_AR933X) selects USB_ARCH_HAS_EHCI which has unmet direct dependencies (USB_SUPPORT) Signed-off-by: David Daney <david.daney@cavium.com> Cc: Paul Gortmaker <paul.gortmaker@windriver.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2012-03-13regulator: Fix the logic of tps65910_get_modeAxel Lin
We actually clear LDO_ST_ON_BIT for standby mode in tps65910_set_mode. Fix the logic in tps65910_get_mode. Supply state (EEPROM bits): ST[1:0] = 00 : Off ST[1:0] = 01 : On high power (ACTIVE) ST[1:0] = 10 : Off ST[1:0] = 11 : On low power (SLEEP) Signed-off-by: Axel Lin <axel.lin@gmail.com> Acked-by: Laxman Dewangan <ldewangan@nvidia.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

2012-03-13staging: drm/omap: use current time for page-flip eventRob Clark
Because we don't have vblank hooked up via drm_irq (which is a bit awkward due to separation between omapdss (which knows the irq #) and omapdrm, for now use gettimeofday to have a semi-sane timestamp in the page-flip event. Otherwise apps like weston drm compositor, which use the timestamp in it's animations, get highly confused.

2012-03-13staging: drm/omap: send page-flip event after endwinRob Clark
The endwin irq indicates that DSS has finished scanning out a buffer. Use this to trigger page-flip event to userspace, so this happens only *after* the previous buffer is finished. Signed-off-by: Rob Clark <rob@ti.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
