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>
2012-03-13target: Fix compatible reservation handling (CRH=1) with legacy RESERVE/RELEASENicholas Bellinger
This patch addresses a bug with target_check_scsi2_reservation_conflict() return checking in target_scsi2_reservation_[reserve,release]() that was preventing CRH=1 operation from silently succeeding in the two special cases defined by SPC-3, and not failing with reservation conflict status when dealing with legacy RESERVE/RELEASE + active SPC-3 PR logic. 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.

Since then any use of "variable length arrays" has become blasphemous. Even in perfectly good, beautiful, perfectly safe code like the one below where the variable length arrays are only used as a sizeof() parameter, for type-safe dynamic structure allocations. GCC is not executing any stack allocation code. I have produced a small file which defines two functions main1(unsigned numdevs) and main2(unsigned numdevs). main1 uses code as before with call to malloc and main2 uses code as of after this patch. I compiled it as: gcc -O2 -S see_asm.c and here is what I get: <see_asm.s> main1: .LFB7: .cfi_startproc mov %edi, %edi leaq 4(%rdi,%rdi), %rdi salq $3, %rdi jmp malloc .cfi_endproc .LFE7: .size main1, .-main1 .p2align 4,,15 .globl main2 .type main2, @function main2: .LFB8: .cfi_startproc mov %edi, %edi addq $2, %rdi salq $4, %rdi jmp malloc .cfi_endproc .LFE8: .size main2, .-main2 .section .text.startup,"ax",@progbits .p2align 4,,15 </see_asm.s> *Exact* same code !!!

2012-03-13xen/xenbus: ignore console/0Stefano Stabellini
Unfortunately xend creates a bogus console/0 frotend/backend entry pair on xenstore that console backends cannot properly cope with. Any guest behavior that is not completely ignoring console/0 is going to either cause problems with xenconsoled or qemu. Returning 0 or -ENODEV from xencons_probe is not enough because it is going to cause the frontend state to become 4 or 6 respectively. The best possible thing we can do here is just ignore the entry from xenbus_probe_frontend.

2012-03-13PM / QoS: Make it possible to expose PM QoS latency constraintsRafael J. Wysocki
A runtime suspend of a device (e.g. an MMC controller) belonging to a power domain or, in a more complicated scenario, a runtime suspend of another device in the same power domain, may cause power to be removed from the entire domain. In that case, the amount of time necessary to runtime-resume the given device (e.g. the MMC controller) is often substantially greater than the time needed to run its driver's runtime resume callback. That may hurt performance in some situations, because user data may need to wait for the device to become operational, so we should make it possible to prevent that from happening. For this reason, introduce a new sysfs attribute for devices, power/pm_qos_resume_latency_us, allowing user space to specify the upper bound of the time necessary to bring the (runtime-suspended) device up after the resume of it has been requested. However, make that attribute appear only for the devices whose drivers declare support for it by calling the (new) dev_pm_qos_expose_latency_limit() helper function with the appropriate initial value of the attribute.

git://git.kernel.org/pub/scm/linux/kernel/git/sarah/xhci into usb-next Hi Greg, Here's my final pull request for 3.4. All the patches have been under review for some time (months in some cases). The ring expansion patches in particular have been tested by both me and Paul Zimmerman from Synopsis. They add support for: - Dynamic ring expansion - New USB 2.1 link PM errata (BESL) - xHCI host controller support for the Synopsis DesignWare 3 IP The dynamic ring expansion patches finally make test 10 of the host-side test pass, instead of failing due to no room on the endpoint ring for the larger transfers. I would have hoped that the ring expansion patchset would make the Point Grey USB 3.0 camera work, but sadly it fails to respond to a control transfer on my test system. This doesn't seem to be a driver bug, but it could be a device or host bug. Felipe has tested the patches to add a platform device to the xHCI driver on the Synopsis DesignWare 3 IP in the TI OMAP5 board. Please pull. Thanks, Sarah Sharp
