This patch removes a bug in enlarge_buffer() that can make a read or write fail under special conditions. After changing TRY_DIRECT_IO to 0 and ST_MAX_SG to 32 in st_options.h, a program that writes a first block of 128k and than a second bigger block (e.g. 256k) fails. The second write returns errno EOVERFLOW, as enlarge_buffer() checks the sg list and detects that it already is full. As enlarge_buffer uses different page allocation orders depending on the size of the buffer needed, the check does not make sense. Signed-off-by:

In direct attach mode, if port features like QoS/Trunk/FEC/CR are enabled, driver can receive PLOGI from the target before firmware notifies lport online to the driver. In case the lport is not yet online and a PLOGI is received, send a reject to the peer port, instead of dropping it on the floor. Signed-off-by:

This patch includes change to enable firmware patch simplication feature. This feature is targeted to address the requirement to have independent patch release for firmware. Prior to 3.2.3, releasing a patch fix for firmware requires changes to bfa, to use new firmware images. But with these changes, if the new firmware is flashed on to the HBA with brocade adapter management utilites, driver uses the new firmware after checking the patch release byte in the firmware version.

do_div() is meant for divisions of 64-bit number by 32-bit numbers. Passing 64-bit divisor types caused issues in the past on 32-bit platforms, cfr. commit ea077b1b ("m68k: Truncate base in do_div()"). As scsi_device.sector_size is unsigned (int), factor should be unsigned int, too. Signed-off-by:

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.

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. Signed-off-by:

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.

Commit 18a4d0a2 (Handle disk devices which can not process medium access commands) was introduced to offline any device which cannot process medium access commands. However, commit 3eef6257 (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:

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.
