The pointer to the sense buffer is fetched by transport_get_sense_data, but this is called by target_complete_ok_work long after pscsi_req_done has freed the struct that contains it. Pass instead the fabric's sense buffer to transport_complete, and copy the data to it directly in transport_complete. Setting SCF_TRANSPORT_TASK_SENSE also becomes a duty of transport_complete.

Paolo Bonzini authored
The error conditions in transport_get_sense_data are superfluous and complicate the code unnecessarily: * SCF_TRANSPORT_TASK_SENSE is checked in the caller; * it's simply part of the invariants of dev->transport->get_sense_buffer that it must be there if transport_complete ever returns 1, and that it must not return NULL. Besides, the entire callback will disappear with the next patch. * similarly in the caller we can expect that sense data is only sent for non-zero cmd->scsi_status.

This patch fixes a long-standing bug with SCSI overflow handling where se_cmd->data_length was incorrectly being re-assigned to the larger CDB extracted allocation length, resulting in a number of fabric level errors that would end up causing a session reset in most cases. So instead now: - Only re-assign se_cmd->data_length durining UNDERFLOW (to use the smaller value) - Use existing se_cmd->data_length for OVERFLOW (to use the smaller value) This fix has been tested with the following CDB to generate an SCSI overflow: sg_raw -r512 /dev/sdc 28 0 0 0 0 0 0 0 9 0 Tested using iscsi-target, tcm_qla2xxx, loopback and tcm_vhost fabric ports. Here is a bit more detail on each case: - iscsi-target: Bug with open-iscsi with overflow, sg_raw returns -3584 bytes of data. - tcm_qla2xxx: Working as expected, returnins 512 bytes of data - loopback: sg_raw returns CHECK_CONDITION, from overflow rejection in transport_generic_map_mem_to_cmd() - tcm_vhost: Same as loopback Reported-by: Roland Dreier <roland@purestorage.com> Cc: Roland Dreier <roland@purestorage.com> Cc: Christoph Hellwig <hch@lst.de> Cc: Boaz Harrosh <bharrosh@panasas.com> Cc: <stable@vger.kernel.org> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>

Here TRANSPORT_IQN_LEN is 224, which is a multiple of 4. Since vhost_tpgt is 2 bytes and abi_version is 4, the total size would be 230. But gcc needs struct size be aligned to first field size, which is 4 bytes, so it pads the structure by extra 2 bytes to the total of 232. This padding is very undesirable in an ABI: - it can not be initialized easily - it can not be checked easily - it can leak information between kernel and userspace Simplest solution is probably just to make the padding explicit.

This patch fixes a regression bug with the handling of zero-length data CDBs within transport_generic_new_cmd() code. The bug was introduced with the following commit as part of the single task conversion work: commit 4101f0a8 Author: Christoph Hellwig <hch@infradead.org> Date: Tue Apr 24 00:25:03 2012 -0400 target: always allocate a single task where the zero-length check for SCF_SCSI_DATA_SG_IO_CDB was incorrectly changed to SCF_SCSI_CONTROL_SG_IO_CDB because of the seperate comment in transport_generic_new_cmd() wrt to control CDBs zero-length handling introduced in: commit 91ec1d35 Author: Nicholas Bellinger <nab@linux-iscsi.org> Date: Fri Jan 13 12:01:34 2012 -0800 target: Add workaround for zero-length control CDB handling So go ahead and change transport_generic_new_cmd() to handle control+data zero-length CDBs in the same manner for this special case. Tested with iscsi-target + loopback fabric port LUNs on 3.6-rc0 code. This patch will also need to be picked up for 3.5-stable.

Following a report of a crash during an automount expire I found that the locking in fs/autofs4/expire.c:get_next_positive_subdir() was wrong. Not only is the locking wrong but the function is more complex than it needs to be. The function is meant to calculate (and dget) the next entry in the list of directories contained in the root of an autofs mount point (an autofs indirect mount to be precise). The main problem was that the d_lock of the owner of the list was not being taken when walking the list, which lead to list corruption under load. The only other lock that needs to be taken is against the next dentry candidate so it can be checked for usability.

On a 2-node machine with 256GB of ram we get 512 lines of console output, which is just too much. This mimicks Yinghai Lu's x86 commit c2b91e2e (x86_64/mm: check and print vmemmap allocation continuous) except that we aren't ever going to get contiguous block pointers in between calls so just print when the virtual address or node changes.

eDP is tons of fun. It turns out that at least the new MacBook Air 5,1 model absolutely doesn't like the new force vdd dance we've introduced in commit 6cb49835 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Sun May 20 17:14:50 2012 +0200 drm/i915: enable vdd when switching off the eDP panel But that patch also tried to fix some neat edp sequence issue with the force_vdd timings. Closer inspection reveals that we've raised force_vdd only to do the aux channel communication dp_sink_dpms. If we move the edp_panel_off below that, we don't need any force_vdd for the disable sequence, which makes the Air happy. Unfortunately the reporter of the original bug that the above commit fixed is travelling, so we can't test whether this regresses things. But my theory is that since we don't check for any power-off -> force_vdd-on delays in edp_panel_vdd_on, this was the actual root-cause of this failure. With that force_vdd dance completely eliminated, I'm hopeful the original bug stays fixed, too. For reference the old bug, which hopefully doesn't get broken by this: https://bugzilla.kernel.org/show_bug.cgi?id=43163 In any case, regression fixers win over plain bugfixes, so this needs to go in asap. v2: The crucial pieces seems to be to clear the force_vdd flag uncoditionally, too, in edp_panel_off. Looks like this is left behind by the firmware somehow. v3: The Apple firmware seems to switch off the panel on it's own, hence we still need to keep force_vdd on, but properly clear it when switching the panel off.
