* LSM/Audit: Introduce generic Audit LSM hooksAhmed S. Darwish2008-04-18
| | | | | | | | | | | | | | | | | Introduce a generic Audit interface for security modules by adding the following new LSM hooks: audit_rule_init(field, op, rulestr, lsmrule) audit_rule_known(krule) audit_rule_match(secid, field, op, rule, actx) audit_rule_free(rule) Those hooks are only available if CONFIG_AUDIT is enabled.

| | | | | | | | | | | | | | | | Introduce inode_getsecid(inode, secid) and ipc_getsecid(ipcp, secid) LSM hooks. These hooks will be used instead of similar exported SELinux interfaces. Let {inode,ipc,task}_getsecid hooks set the secid to 0 by default if CONFIG_SECURITY is not defined or if the hook is set to NULL (dummy).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | bsg_register_queue() takes a ref to struct device that a caller passes. For example, bsg takes a ref to the sdev_gendev for scsi devices. However, bsg doesn't inrease the refcount in fops->open. So while an application opens a bsg device, the scsi device that the bsg device holds can go away (bsg also takes a ref to a queue, but it doesn't prevent the device from going away). With this patch, bsg increases the refcount of struct device in fops->open and decreases it in fops->release.

| * [SCSI] qla2xxx: Add midlayer target/device reset support.Andrew Vasquez2008-04-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that infrastructure is present within the midlayer and there is a clear distinction between what is expected from a device and target reset, convert the current device-reset codes to a target-reset, and add codes to perform a proper device-reset (LUN reset). In the process of adding reset support, collapse and consolidate large sections of mailbox-command (TMF issuance) codes, generalize the two 'wait-for-commands-to-complete' functions, and add a generic-reset routine for use by midlayer reset functions.

| * [SCSI] qla2xxx: Add Flash Descriptor Table layout support.Andrew Vasquez2008-04-07
| | | | | | | | | | | | | | | | | | | | | | The Flash Descriptor Table (FDT) present on many recent HBAs encodes flash accessing characteristics of the flash-part used on the HBA. Use this information during flash manipulation (writes) rather than using specific hard-coded values based on queried manufacturer and device IDs.

Another step in the migration towards a cleaner (less-crusty) driver. Signed-off-by: Andrew Vasquez <andrew.vasquez@qlogic.com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>

| | | | | | | | | | | | | | | | | | | | Recent ISPs have a region within FLASH which acts as a repository for the logging of serious hardware and software failures. Currently, the region is large enough to support up to 255 entries. Signed-off-by: Andrew Vasquez <andrew.vasquez@qlogic.com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
| * [SCSI] qla2xxx: Add FC-transport Asynchronous Event Notification support.Andrew Vasquez2008-04-07
| | | | | | | | | | | | | | | | | | | | | | | | | | Supported events include LIP, LIP reset, RSCN, link up, and link down. To support AEN (and additional forthcoming features), we also introduce a simple deferred-work construct to manage events which require a non-atomic sleeping-capable context. This work-list is processed as part of the driver's standard DPC routine.

| | | | | | | | | | | | | | | | | | | | | | There's no need to use the heavier (albiet safer) *_irq[save|restore]() locking primitives within the driver's interrupt handlers, interrupts are guaranteed to be non-reentrant.
