2010-04-11[SCSI] bnx2i: Bug fixes related to MTU change issue when there are active ↵Anil Veerabhadrappa
iscsi sessions bnx2i driver has to wait and cleanup all iscsi endpoints before returning from bnx2i_stop(). This is to make sure all chip resources are freed before chip is reset. As the requirements for 1G and 10G chipsets is different, added per-device 'hba_shutdown_tmo' parameter to adapter structure If the connections are not torn down by the daemon within this timeout period, 'cid's will be leaked in 10G device. 1G devices are more flexible and do not leak any resources because the whole chip ports gets reset when MTU is changed or ethtool selftest is run fixed a minor issue in bnx2i_ep_poll() which unnecessarily forced error return code when driver timed out waiting for TCP connect request to complete Signed-off-by: Anil Veerabhadrappa <anilgv@broadcom.com> Reviewed-by: Mike Christie <michaelc@cs.wisc.edu> Signed-off-by: James Bottomley <James.Bottomley@suse.de>

When I made this patch: b64e77f70b8c11766e967e3485331a9e6ef01390 it was to solve a problem where we were already on the waitqueue becuase a connection problem/logout caused us to be on there when we were cleaning up the session. If we happen to get on queue for more normal reasons like their just does not happen to be any send space at the same time we are closing the connection we hit a race and get stuck in the wait. We should not check if the waitqueue is active because we could race with the network code. If the network xmit code is just about to enter the prepare to wait when we check for the waitqueue to be active then we will miss each other and the network code will fall into the wait and we will not run wake_up.

2010-03-30include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo
implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

2010-03-27[SCSI] qla1280: retain firmware for error recoveryMichael Reed
The qla1280 driver acquires its firmware via udev. During boot the firmware is located in the initrd. If, after root is mounted, the adapter needs to reload firmware (host reset), the firmware load may fail if the root device is on the adapter being reset. This patch modifies qla1280 to retain the firmware loaded via the initial request_firmware() for use during error recovery.

2010-03-27[SCSI] advansys: fix regression with request_firmware changeHerton Ronaldo Krzesinski
On newer kernels users of advansys module are reporting system hang when trying to load it without firmware files present. After looking closely at description on https://qa.mandriva.com/show_bug.cgi?id=53220, I think this is related to commit "[SCSI] advansys: use request_firmware". The problem is that after switch to request_firmware, asc_dvc->err_code isn't being set when firmware files aren't found or loading fails. err_code is used by the driver to judge if there was a fatal error or not, as can be seen for example on advansys_board_found, which will only return -ENODEV when err_code is set. Because err_code isn't being set when request_firmware fails, this is a change of behaviour of the code before request_firmware addition, making it continue to load and it fails later as the firmware wasn't really loaded.

2010-03-27[SCSI] libiscsi: Fix recovery slowdown regressionMike Christie
We could be failing/stopping a connection due to libiscsi starting recovery/cleanup, but the xmit path or scsi eh thread path could be dropping the connection at the same time. As a result the session->state gets set to failed instead of in recovery. We end up not blocking the session and so the replacement timeout never gets started and we only end up failing the IO when scsi_softirq_done sees that the cmd has been running for (cmd->allowed + 1) * rq->timeout secs. We used to fail the IO right away so users are seeing a long delay when using dm-multipath. This problem was added in 2.6.28.

2010-03-08[SCSI] scsi_transport_fc: Fix synchronization issue while deleting vportGal Rosen
The issue occur while deleting 60 virtual ports through the sys interface /sys/class/fc_vports/vport-X/vport_delete. It happen while in a mistake each request sent twice for the same vport. This interface is asynchronous, entering the delete request into a work queue, allowing more than one request to enter to the delete work queue. The result is a NULL pointer. The first request already delete the vport, while the second request got a pointer to the vport before the device destroyed. Re-create vport later cause system freeze. Solution: Check vport flags before entering the request to the work queue.

Otherwise (if also having HOTPLUG=y) unbinding and binding a device to the driver via sysfs will result in an oops as does a device being registered late.
