Problem: HW DDP context was not invalidated in case of ABORTS, etc... This leads to the problem where memory pages which are used for DDP as user descriptor could get reused for some other purpose (such as to satisfy new memory allocation request either by kernel or user mode threads) and since HW DDP context was not invalidated, HW continue to write to those pages, hence causing memory corruption. Fix: Either on incoming ABORTS or due to exchange time out, allowed the target to cleanup HW DDP context if it was setup for respective ft_cmd. Added new function to perform this cleanup, furthur it can be enhanced for other cleanup activity. Fix ft_recv_write_data() to properly handle fc_frame_payload_get to return pointer to payload if it exist. If there is no payload which is most common case (+ve case in case if DDP is working as expected, it will return NULL. Yes, scope of buf is limited to printk. Invalidation of HW context (which is done inside ft_invl_hw_context() is necessary in SUCCESS and FAILURE case of DDP. Hence invalidation is DONE as long as there was DDP setup (whether it worked correctly or not, NOTE: For some reason, if there is any error w.r.t DDP such as out of order packet reception, HW simply post the full packet in rx queue.

This patch fixes a bug in transport_handle_cdb_direct() usage with target_core where transport_generic_wait_for_tasks() was bypassing active I/O + usage of cmd->t_transport_stop_comp because cmd->t_transport_active=1 was not being set before dispatching with transport_generic_new_cmd(). The fix follows existing usage in transport_generic_handle_cdb*() -> transport_add_cmd_to_queue() and set these directly, as well as handle transport_generic_new_cmd() exceptions for QUEUE_FULL and CHECK_CONDITION instead of propigating up to RX context fabric code. The bug was manifesting itself with the following SLUB poison overwritten warnings with iscsi-target v4.1 LUNs using the new process context direct operation during session reinstatement with active I/O exception handling: [885410.498267] ============================================================================= [885410.621622] BUG lio_cmd_cache: Poison overwritten [885410.621791] ----------------------------------------------------------------------------- [885410.621792] [885410.623420] INFO: 0xffff880000cf3750-0xffff880000cf378d.

The Linux-iSCSI.org target module is a full featured in-kernel software implementation of iSCSI target mode (RFC-3720) for the current WIP mainline target v4.1 infrastructure code for the v3.1 kernel. More information can be found here: http://linux-iscsi.org/wiki/ISCSI This includes support for: * RFC-3720 defined request / response state machines and support for all defined iSCSI operation codes from Section 10.2.1.2 using libiscsi include/scsi/iscsi_proto.h PDU definitions * Target v4.1 compatible control plane using the generic layout in target_core_fabric_configfs.c and fabric dependent attributes within /sys/kernel/config/target/iscsi/ subdirectories. * Target v4.1 compatible iSCSI statistics based on RFC-4544 (iSCSI MIBS) * Support for IPv6 and IPv4 network portals in M:N mapping to TPGs * iSCSI Error Recovery Hierarchy support * Per iSCSI connection RX/TX thread pair scheduling affinity * crc32c + crc32c_intel SSEv4 instruction offload support using libcrypto * CHAP Authentication support using libcrypto * Conversion to use internal SGl allocation with iscsit_alloc_buffs() -> transport_generic_map_mem_to_cmd() (nab: Fix iscsi_proto.h struct scsi_lun usage from linux-next in commit: iscsi: Use struct scsi_lun in iscsi structs instead of u8[8]) (nab: Fix 32-bit compile warnings) Reviewed-by:

sbi->s_mutex isn't needed for isofs at all so we can just remove it. Generally, since isofs is always mounted read-only, filesystem structure cannot change under us. So buffer_head contents stays constant after it's filled in. That leaves us with possible changes of global data structures. Superblock changes only during filesystem mount (even remount does not change it), inodes are only filled in during reading from disk. So there are no changes of these structures to bother about. Arguments why sbi->s_mutex can be removed at each place: isofs_readdir: Accesses sb, inode, filp, local variables => s_mutex not needed isofs_lookup: Protected by directory's i_mutex. Accesses sb, inode, dentry, local variables => s_mutex not needed rock_ridge_symlink_readpage: Protected by page lock. Accesses sb, inode, local variables => s_mutex not needed. Signed-off-by:

We don't generate IN_DELETE_SELF on victim of overwriting rename() if it happens to be a directory. Trivially fixed by doing to ->i_nlink what we do ->pino_nlink a couple of lines later in jffs2_rename(). Signed-off-by:
