| * PCI: Rework config space blocking servicesJan Kiszka2012-01-062-7/+61
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | pci_block_user_cfg_access was designed for the use case that a single context, the IPR driver, temporarily delays user space accesses to the config space via sysfs. This assumption became invalid by the time pci_dev_reset was added as locking instance. Today, if you run two loops in parallel that reset the same device via sysfs, you end up with a kernel BUG as pci_block_user_cfg_access detect the broken assumption. This reworks the pci_block_user_cfg_access to a sleeping service pci_cfg_access_lock and an atomic-compatible variant called pci_cfg_access_trylock. The former not only blocks user space access as before but also waits if access was already locked. The latter service just returns false in this case, allowing the caller to resolve the conflict instead of raising a BUG. Adaptions of the ipr driver were originally written by Brian King.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There could be multiple userspace entities creating/destroying/ recoverying sessions and also the kernel's iscsi drivers could be doing this too. If the userspace apps do try to manage the kernel ones it can get the driver/fw out of sync and cause the user to loose the root disk, oopses or ping ponging becasue userspace wants to do one thing but the kernel manager thought we are trying to do another. This patch fixes the problem by just exporting the pid of the entity that created the session. Userspace programs like iscsid, iscsiadm, iscsistart, qlogic's tools, etc, can then figure out which sessions they own and only manage them.

| * | [SCSI] mpt2sas : Fix for memory allocation error for large host creditsnagalakshmi.nandigama@lsi.com2011-12-152-58/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The amount of memory required for tracking chain buffers is rather large, and when the host credit count is big, memory allocation failure occurs inside __get_free_pages. The fix is to limit the number of chains to 100,000. In addition, the number of host credits is limited to 30,000 IOs. However this limitation can be overridden this using the command line option max_queue_depth. The algorithm for calculating the reply_post_queue_depth is changed so that it is equal to (reply_free_queue_depth + 16), previously it was (reply_free_queue_depth * 2).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When an I/O request to a WarpDrive is timed out by SML and if the I/O request to the WarpDrive is sent as direct I/O then the aborted direct I/O will be retried as normal Volume I/O and which results in failure of Target Reset and results in host reset. The fix is to not retry a failed IO to volume when the original IO was sent as direct IO with an ioc status MPI2_IOCSTATUS_SCSI_TASK_TERMINATED.

| * | [SCSI] be2iscsi: cleanup a min_t() callDan Carpenter2011-12-151-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | "sense_len" was declared as int type but actually it only stores a u16 value that comes from hardware. The cast to u16 in min_t() confuses static analysis because it truncates the int to u16 so I've fixed the declaration to reflect that "sense_len" is just a u16. Also there was a call to cpu_to_be16() which I've changed to be16_to_cpu(). The functions are equivalent, but obviously the hardware is big endian and we're doing the min_t() comparison on CPU endian values. This whole patch is just a cleanup and doesn't affect how the code works.
