This includes the following highlights: - Fix long-standing qla2xxx target bug where certain fc_port_t state transitions could cause the internal session b-tree list to become out-of-sync. (Roland) - Fix task management double free of se_cmd descriptor in exception path for users of target_submit_tmr(). (nab) - Re-introduce simple NOP emulation of REZERO_UNIT, SEEK_6, and SEEK_10 SCSI-2 commands in order to support legacy initiators that still require them. (Bernhard) Note these three patches are also CC'ed to stable. Also, there a couple of outstanding (external) regressions that are still being tracked down for tcm_fc(FCoE) and tcm_vhost fabrics for v3.7.0 code, so please expect another PULL as these issues identified -> resolved." * git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending: target: reintroduce some obsolete SCSI-2 commands target: Fix double-free of se_cmd in target_complete_tmr_failure qla2xxx: Update target lookup session tables when a target session changes tcm_qla2xxx: Format VPD page 83h SCSI name string according to SPC qla2xxx: Add missing ->vport_slock while calling qlt_update_vp_map

There are still clients out there which use these old SCSI-2 commands. This mainly happens when running VMs with legacy guest systems, connected via SCSI command pass-through to iSCSI targets. Make them happy and return status GOOD. Many real SCSI disks or external iSCSI storage devices still support these old commands. So let's make LIO backward compatible as well. This patch adds support for the previously removed SEEK_10 and additionally the SEEK_6 and REZERO_UNIT commands.

| | * target: Fix double-free of se_cmd in target_complete_tmr_failureNicholas Bellinger2012-10-271-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fabric drivers currently expect to internally release se_cmd in the event of a TMR failure during target_submit_tmr(), which means the immediate call to transport_generic_free_cmd() after TFO->queue_tm_rsp() from within target_complete_tmr_failure() workqueue context is wrong. This is done as some fabrics expect TMR operations to be acknowledged before releasing the descriptor, so the assumption that core is releasing se_cmd associated TMR memory is incorrect. This fixes a OOPs where transport_generic_free_cmd() was being called more than once. This bug was originally observed with tcm_qla2xxx fabric ports.

| | * qla2xxx: Update target lookup session tables when a target session changesRoland Dreier2012-10-263-14/+85
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is possible for the target code to change the loop_id or s_id of a target session in reaction to an FC fabric change. However, the session structures are stored in tables that are indexed by these two keys, and if we just change the session structure but leave the pointers to it in the old places in the table, havoc can ensue. For example, a new session might come along that should go in the old slot in the table and overwrite the old session pointer. To handle this, add a new tgt_ops->update_sess() method that also updates the "by loop_id" and "by s_id" lookup tables when a session changes, so that the keys where a session pointer is stored in these tables always matches the keys in the session structure itself.

| | * tcm_qla2xxx: Format VPD page 83h SCSI name string according to SPCRoland Dreier2012-10-262-1/+5

The first hexadecimal digit shall be the most significant four bits of the first byte (i.e., most significant byte) of the EUI-64 based identifier; b) the four UTF-8 characters 'naa.' concatenated with 16 or 32 hexadecimal digits for an NAA identifier (see 7.8.6.6). The first hexadecimal digit shall be the most significant four bits of the first byte (i.e., most significant byte) of the NAA identifier; or c) the four UTF-8 characters 'iqn.' concatenated with an iSCSI Name for an iSCSI-name based identifier (see iSCSI). However, the .tpg_get_wwn method for tcm_qla2xxx formats the WWN so the SCSI name string looks like "52:4a:93:7d:24:5f:b2:12,t,0x0001". This patch corrects the code so that VPD 83h gives a SPC-compliant SCSI name string like "naa.524a937d245fb212,t,0x0001" while leavig other uses alone (so configfs will still work with ':' separated WWNs).

It is used when including 'Replacement' devices. The consequence is that assembling an array which contains a replacement will misbehave and either not include the replacement, or not include the device being replaced. Though this doesn't lead directly to data corruption, it could lead to reduced data safety. So use mddev->raid_disks, which is initialised, instead.

That was on an older kernel, and I can't reproduce exactly the same thing upstream, but I think the fix is appropriate in any case. Thanks to Mike Snitzer for pointing out the problem.

The driver has its own implementation of these functions, which can pick the correct register depending on the CPU being used. The functions do however use the gc->mask_cache value. The call to irq_setup_generic_chip() was passing IRQ_GC_INIT_MASK_CACHE, which caused the gc->mask_cache to be initialized to the contents of some random register. This resulted in unexpected interrupts been delivered from random GPIO lines.

The title has been updated slightly to reflect (what should be) the final fix. When a GPIO is freed or shutdown, we need to ensure that any debounce settings are cleared and if the GPIO is the only GPIO in the bank that is currently using debounce, then disable the debounce clock as well to save power. Currently, the debounce settings are not cleared on a GPIO free or shutdown and so during a context restore on subsequent off-mode transition, the previous debounce values are restored from the shadow copies (bank->context.debounce*) leading to mismatch state between driver state and hardware state. This was discovered when board code was doing gpio_request_one() gpio_set_debounce() gpio_free() which was leaving the GPIO debounce settings in a confused state. If that GPIO bank is subsequently used with off-mode enabled, bogus state would be restored, leaving GPIO debounce enabled which then prevented the CORE powerdomain from transitioning. To fix this, introduce a new function called _clear_gpio_debounce() to clear any debounce settings when the GPIO is freed or shutdown. If this GPIO is the last debounce-enabled GPIO in the bank, the debounce will also be cut. Please note that we cannot use _gpio_dbck_disable() to disable the debounce clock because this has been specifically created for the gpio suspend path and is intended to shutdown the debounce clock while debounce is enabled. Special thanks to Kevin Hilman for root causing the bug. This fix is a collaborative effort with inputs from Kevin Hilman, Grazvydas Ignotas and Santosh Shilimkar. Testing: - This has been unit tested on an OMAP3430 Beagle board, by requesting a gpio, enabling debounce and then freeing the gpio and checking the register contents, the saved register context and the debounce clock state. - Kevin Hilman tested on 37xx/EVM board which configures GPIO debounce for the ads7846 touchscreen in its board file using the above sequence, and so was failing off-mode tests in dynamic idle. Verified that off-mode tests are passing with this patch.

Unfortunately, this last part was not done until now, causing for example the LEDs to not be properly set to their default initial value. This patch fixes this by calling the mvebu_gpio_set() function from mvebu_gpio_direction_output() before configuring the GPIO as an output GPIO.

This causes test runs to immediately stop. Over the past 6 or 7 years we've added hacks like explicit unmount -d commands for loop mounts, losetup -d after unmount -d fails, etc, but still the problems persist. Recently, the frequency of loop related failures increased again to the point that xfstests 259 will reliably fail with a stray loop device that was not torn down. That is despite the fact the test is above as simple as it gets - loop 5 or 6 times running mkfs.xfs with different paramters: lofile=$(losetup -f) losetup $lofile "$testfile" "$MKFS_XFS_PROG" -b size=512 $lofile >/dev/null || echo "mkfs failed!" sync losetup -d $lofile And losteup -d $lofile is failing with EBUSY on 1-3 of these loops every time the test is run. Turns out that blkid is running simultaneously with losetup -d, and so it sees an elevated reference count and returns EBUSY. But why is blkid running? It's obvious, isn't it? udev has decided to try and find out what is on the block device as a result of a creation notification. And it is racing with mkfs, so might still be scanning the device when mkfs finishes and we try to tear it down. So, make losetup -d force autoremove behaviour. That is, when the last reference goes away, tear down the device. xfstests wants it *gone*, not causing random teardown failures when we know that all the operations the tests have specifically run on the device have completed and are no longer referencing the loop device.

Just moved the allocation of floppy_wq before the loop, and adjusted the code accordingly.
