| | | | | | | | | | | | | | | | | | | | | | | | | | | | All ->execute_task instances now need to complete the I/O explicitly, which can either happen synchronously or asynchronously. Note that a lot of the CDB emulations appear to return success even if some lowlevel operations failed. Given that this is an existing issue this patch doesn't change that fact.

| * target: Add generic active I/O shutdown logicNicholas Bellinger2011-11-041-5/+127
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds the initial pieces of generic active I/O shutdown logic. This is intended to be a 'opt-in' feature for fabric modules that includes the following functions to provide a mechinism for fabric modules to track se_cmd via se_session->sess_cmd_list: *) target_get_sess_cmd() - Add se_cmd to sess->sess_cmd_list, called from fabric module incoming I/O path. *) target_put_sess_cmd() - Check for completion or drop se_cmd from ->sess_cmd_list *) target_splice_sess_cmd_list() - Splice active I/O list from ->sess_cmd_list to ->sess_wait_list, can called with HW fabric lock held. *) target_wait_for_sess_cmds() - Walk ->sess_wait_list waiting on individual ->cmd_wait_comp. Optional transport_wait_for_tasks() call. target_splice_sess_cmd_list() is allowed to be called under HW fabric lock, and performs the splice into se_sess->sess_wait_list and set se_cmd->cmd_wait_set. Then target_wait_for_sess_cmds() walks the list waiting for individual target_put_sess_cmd() fabric callbacks to complete. It also adds TFO->check_release_cmd() to split the completion and memory release calls, where a fabric module uses target_put_sess_cmd() to check for I/O completion during session shutdown. This is currently pushed out into fabric modules as current fabric code may sleep here waiting for TFO->check_stop_free() to complete in main response path, and because target_wait_for_sess_cmds() calling TFO->release_cmd() to free fabric descriptor memory directly.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch drops TRANSPORT_FREE_CMD_INTR usage from target core, which includes the removal of transport_generic_free_cmd_intr() symbol, TRANSPORT_FREE_CMD_INTR usage in transport_processing_thread(), and special case LUN_RESET handling to skip TRANSPORT_FREE_CMD_INTR processing in core_tmr_drain_cmd_list(). We now expect that fabric modules will use an internal workqueue to provide process context when releasing se_cmd descriptor resources via transport_generic_free_cmd().

| * target: Make TFO->check_stop_free return free statusNicholas Bellinger2011-11-024-6/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch converts target_core_fabric_ops->check_stop_free() usage in transport_cmd_check_stop() and associated fabric module usage to return '1' when the passed se_cmd has been released directly within ->check_stop_free(), or return '0' when the passed se_cmd has not been released. This addresses an issue where transport_cmd_finish_abort() -> transport_cmd_check_stop_to_fabric() was leaking descriptors during LUN_RESET for modules using ->check_stop_free(), but not directly releasing se_cmd in all cases.

| * iscsi-target: Fix non-immediate TMR handlingNicholas Bellinger2011-11-021-4/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch addresses two issues with non immediate TMR handling in iscsit_handle_task_mgt_cmd(). The first involves breakage due to v3.1-rc conversion of iscsit_sequence_cmd(), which upon good status would hit the iscsit_add_reject_from_cmd() block of code. This patch adds an explict check for CMDSN_ERROR_CANNOT_RECOVER. The second adds a check to return when non immediate TMR operation is detected after iscsit_ack_from_expstatsn(), as iscsit_sequence_cmd() -> iscsit_execute_cmd() will have called transport_generic_handle_tmr() for the non immediate TMR case already.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After the list_del() in core_tmr_drain_tmr_list(), core_tmr_release_req() would list_del() the same object again. Call graph: core_tmr_drain_tmr_list transport_cmd_finish_abort_tmr transport_generic_remove transport_free_se_cmd core_tmr_release_req So use list_del_init(), as list_del() of an initialized list_head is safe and essentially a nop. In the CONFIG_DEBUG_LIST case, list_del() actually poisons the list_head, but that is fine as we free the object directly afterwards.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch changes target core to also check for -ENOMEM from fabric callbacks to signal QUEUE_FULL status, instead of just -EAGAIN in order to catch a larger set of fabric failure cases that want to trigger QUEUE_FULL logic. This includes the callbacks for ->write_pending(), ->queue_data_in() and ->queue_status(). It also makes transport_generic_write_pending() return zero upon QUEUE_FULL, and removes two unnecessary -EAGAIN checks to catch write pending QUEUE_FULL cases from transport_generic_new_cmd() failures in transport_handle_cdb_direct() and transport_processing_thread():TRANSPORT_NEW_CMD_MAP state.

| * tcm_loop: Add explict read buffer memset for SCF_SCSI_CONTROL_SG_IO_CDBNicholas Bellinger2011-10-261-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch addresses an issue with buggy userspace code sending I/O via scsi-generic that does not explictly clear their associated read buffers. It adds an explict memset of the first SGL entry within tcm_loop_new_cmd_map() for SCF_SCSI_CONTROL_SG_IO_CDB payloads that are currently guaranteed to be a single SGL by target-core code. This issue is a side effect of the v3.1-rc1 merge to remove the extra memcpy between certain control CDB types using a contigious + cleared buffer in target-core, and performing a memcpy into the SGL list within tcm_loop. It was originally mainfesting itself by udev + scsi_id + scsi-generic not properly setting up the expected /dev/disk/by-id/ symlinks because the INQUIRY payload was containing extra bogus data preventing the proper NAA IEEE WWN from being parsed by userspace.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This removes the use of the special "macbookair_fn_keys" keyboard translation table for the MacBookAir4,x models (ie the 2011 refresh). They use the standard apple_fn_keys[] translation. Apparently only the old MacBook Air's need a different translation table. This mirrors the change that commit da617c7cb915 ("HID: consolidate MacbookAir 4,1 mappings") did for the WELLSPRING6A ones, but does it for the WELLSPRING6 model used on the MacBookAir4,2.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Interrupt handler in MPC8xxx GPIO driver is missing the call to PIC EOI (end of interrupt) handler. As a result, at least on 85XX systems, GPIO interrupt is delivered only once. This patch adds the missing EOI call. Tested on custom P1022 board.

| * | | | | powerpc/85xx: Add 'fsl,pq3-gpio' compatiable for GPIO driverKumar Gala2011-11-031-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Support MPC85xx platforms outside of MPC8572/MPC8536. The MPC8572/MPC8536 have an erratum that is worked around based on having "fsl,mpc8572-gpio" in the compatiable list. All other MPC85xx SoCs don't require this workaround and thus utilize the 'fsl,pq3-gpio' compatiable. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

Finally, move selection of REQUIRE_GPIOLIB or WANTS_OPTIONAL_GPIOLIB to the platforms, because this option is per-platform and not per-driver.

On OPAL v1 we have hvc0 mapped to whatever console the system was configured for (network or hvsi serial port) via the service processor. On OPAL v2 we have hvcN mapped to the Nth console provided by OPAL which generally corresponds to: hvc0 : network console (raw protocol) hvc1 : serial port S1 (hvsi) hvc2 : serial port S2 (hvsi) Note: At this point, early debug console only works with OPAL v1 and shouldn't be enabled in a normal kernel.

Instead change that to overwrite if "data" is non empty after the bootargs check. It allows arch code to have other mechanisms to retrieve the command line prior to parsing the device-tree. Note: CONFIG_CMDLINE_FORCE case should ideally be handled elsewhere as it won't work as it-is if the device-tree has no /chosen node Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> CC: devicetree-discuss@lists-ozlabs.org CC: Grant Likely <grant.likely@secretlab.ca> Acked-by: Grant Likely <grant.likely@secretlab.ca>

The concern is that it's getting these definitions via mach/system.h, which is supposed to only be included by arch/arm/kernel/process.c. As this header is scheduled for cleanup (and elimination) keeping the status quo will cause build errors. So lets fix properly and independent of the future work.
