2013-12-19[SCSI] be2iscsi: fix memory leak in error pathGeyslan G. Bem1-5/+3
There are two memory leaks in cases 'ISCSI_NET_PARAM_VLAN_ID' and 'ISCSI_NET_PARAM_VLAN_PRIORITY' and also a potential junk pointer free if mgmt_get_if_info() returns error because if_info will be unset and it is stack allocated.

do_div() is meant for divisions of 64-bit number by 32-bit numbers.

2013-12-19[SCSI] Set the minimum valid value of 'eh_deadline' as 0Ren Mingxin3-28/+59
The former minimum valid value of 'eh_deadline' is 1s, which means the earliest occasion to shorten EH is 1 second later since a command is failed or timed out. But if we want to skip EH steps ASAP, we have to wait until the first EH step is finished. If the duration of the first EH step is long, this waiting time is excruciating. So, it is necessary to accept 0 as the minimum valid value for 'eh_deadline'. According to my test, with Hannes' patchset 'New EH command timeout handler' as well, the minimum IO time is improved from 73s (eh_deadline = 1) to 43s(eh_deadline = 0) when commands are timed out by disabling RSCN and target port.

2013-12-19[SCSI] Unlock accesses to eh_deadlineHannes Reinecke1-35/+9
32bit accesses are guaranteed to be atomic, so we can remove the spinlock when checking for eh_deadline. We only need to make sure to catch any updates which might happened during the call to time_before(); if so we just recheck with the correct value.

2013-12-19[SCSI] improved eh timeout handlerHannes Reinecke4-14/+156
When a command runs into a timeout we need to send an 'ABORT TASK' TMF. This is typically done by the 'eh_abort_handler' LLDD callback. Conceptually, however, this function is a normal SCSI command, so there is no need to enter the error handler. This patch implements a new scsi_abort_command() function which invokes an asynchronous function scsi_eh_abort_handler() to abort the commands via the usual 'eh_abort_handler'. If abort succeeds the command is either retried or terminated, depending on the number of allowed retries. However, 'eh_eflags' records the abort, so if the retry would fail again the command is pushed onto the error handler without trying to abort it (again); it'll be cleared up from SCSI EH.

2013-12-19[SCSI] Fix erratic device offline during EHJames Bottomley2-23/+29
Commit 18a4d0a22ed6c54b67af7718c305cd010f09ddf8 (Handle disk devices which can not process medium access commands) was introduced to offline any device which cannot process medium access commands. However, commit 3eef6257de48ff84a5d98ca533685df8a3beaeb8 (Reduce error recovery time by reducing use of TURs) reduced the number of TURs by sending it only on the first failing command, which might or might not be a medium access command. So in combination this results in an erratic device offlining during EH; if the command where the TUR was sent upon happens to be a medium access command the device will be set offline, if not everything proceeds as normal. This patch moves the check to the final test, eliminating this problem. Signed-off-by: Hannes Reinecke <hare@suse.de> Signed-off-by: James Bottomley <JBottomley@Parallels.com>
2013-12-19[SCSI] aci7xxx_old: delete decade+ obsolete driverPaul Gortmaker11-16059/+0
After getting warnings in an allyesconfig build[1] from this driver, I decided to remind myself just how old it was, and whether it warranted fixing. In the Kconfig help text, I found: "This driver will eventually be phased out entirely" Going back to the history archive, I see the line was added[2] in Feb 2002, when we moved from v2.4.2.1 ---> v2.4.2.2 So, with over a decade of notification, and multiple major releases since then, I think we can justify removing this. Currently we have people wasting time building it during routine testing, and then wasting more time re-researching the known reported warnings, only to find that nobody really is willing to integrate the fixes[3] for it. A quick search didn't seem to indicate any active user base for it. If someone happens to have a quirky _old_ card that the eleven year old "new" driver doesn't work with, then it is entirely reasonable that they stick with a kernel version that predates this removal.

If we become disconnected from the PCI bus/PCIe fabric, there can be long delays in register reads which can cause erroneous decisions to be made and cause a soft lockup if a lock is held too long. As a preventative measure, check for a disconnection (register reads that return -1) and then disable the board if we find ourselves in this condition. For now, check in our interrupt handlers and the per adapter one second timer.

2013-12-19[SCSI] hpsa: prevent stalled i/oStephen M. Cameron2-2/+31
If a fifo full condition is encountered, i/o requests will stack up in the h->reqQ queue. The only thing which empties this queue is start_io, which only gets called when new i/o requests come in. If none are forthcoming, i/o in h->reqQ will be stalled. To fix this, whenever fifo full condition is encountered, this is recorded, and the interrupt handler examines this to see if a fifo full condition was recently encountered when a command completes and will call start_io to prevent i/o's in h->reqQ from getting stuck. I've only ever seen this problem occur when running specialized test programs that pound on the the CCISS_PASSTHRU ioctl. Signed-off-by: Stephen M.
