The check for module state MODULE_STATE_LIVE is no longer required for LLDs, as libfcoe transport takes care of it. Reference: http://marc.info/?l=linux-scsi&m=129989565903046&w=2Signed-off-by:

bnx2x now uses seperate MTUs for networking and FCoE. FCoE MTU is fixed to 2500 and bnx2fc now needs to match this logic by using FCOE_MTU instead of netdev->mtu. Signed-off-by:

bnx2fc only operates on bnx2x hardware devices and not master bonding devices, so there is no need to check for bonding. Even if the bnx2x device is "enslaved" into a bonding device, FCoE is unaffected as it has its own MAC address and queues. Signed-off-by:

Cleanup commands are issued to the firmware to cleanup any stuck ios that are supposed to be implicitly aborted. In the worst case we can have all scsi ios filling up the free_list and we may not be able to allocate cleanup tasks. So the driver has to reserve free_list entries to be able to allocate the cleanup tasks. This reserve free_list common to all cpus is allocated as one additional entry in the per cpu free_lists. In bnx2fc_cmd_alloc(), there is a related fix to use get_cpu() for the free_list_index. This will prevent using the wrong index if the CPU is preempted. Signed-off-by:

With kernel debugging enabled, holding cq_lock when calling bnx2fc_free_session_resc() which calls iounmap() leads to a warning stack trace [INFO: HARDIRQ-safe -> HARDIRQ-unsafe lock order detected]. iounmap() grabs a HARDIRQ-unsafe vmlist lock, so holding spin_lock_bh(cq_lock) when calling iounmap() will trigger the LOCKDEP warning. Since cq_lock is required only to guard against deletion, hold the lock just before freeing the cq. Signed-off-by:

Added new hardware device 0x28b interface for PMC-Sierra's SRC based controller family. - new src.c file for 0x28b specific functions - new XPORT header required - sync. command interface: doorbell bits shifted (SRC_ODR_SHIFT, SRC_IDR_SHIFT) - async. Interface: different inbound queue handling, no outbound I2O queue available, using doorbell ("PmDoorBellResponseSent") and response buffer on the host ("host_rrq") for status - changed AIF (adapter initiated FIBs) interface: "DoorBellAifPending" bit to inform about pending AIF, "AifRequest" command to read AIF, "NoMoreAifDataAvailable" to mark the end of the AIFs Signed-off-by:Mahesh Rajashekhara <aacraid@pmc-sierra.com> Signed-off-by:

In drivers/target/target_core_transport.c::transport_generic_get_mem() there are a few potential memory leaks in the error paths. This patch makes sure that we free previously allocated memory when other allocations fail. It also moves some work (INIT_LIST_HEAD() and assignment to se_mem->se_len) below all the allocations so that if something fails we don't do the work at all. Signed-off-by:

This patch addresses the majority of sparse warnings and adds proper locking annotations. It also fixes the dubious one-bit signed bitfield, for which the signed one-bit types can be 0 or -1 which can cause a problem if someone ever checks if (foo->lu_gp_assoc == 1). The current code is fine because everyone just checks zero vs non-zero. But Sparse complains about it so lets change it. The warnings look like this: include/target/target_core_base.h:228:26: error: dubious one-bit signed bitfield Signed-off-by:

This patch removes a legacy struct se_hba->hba_dev_list -> se_release_device_for_hba() list walk in core_delete_hba(), which is no longer required while using configfs VFS level parent/child struct config_group dependency referencing. The reason is because any struct se_hba->hba_dev_list-> struct se_device members are going to have to be released via: rmdir /sys/kernel/config/target/core/$HBA/* before rmdir release of struct se_hba via target_core_configfs.c: target_core_call_delhbafromtarget() -> core_delete_hba() rmdir /sys/kernel/config/target/core/$HBA to release struct se_hba in core_delete_hba(). This patch also removes the legacy se_clear_dev_ports() function, which is left-over pre-configfs shutdown logic for when se_free_virtual_device() was responsible for walking struct se_device->dev_sep_list and calling core_dev_del_lun() for each individual active struct se_port->se_lun. The reason this can be removed is because all struct se_device->dev_sep_list -> struct se_port communication is done via configfs symlinks, which means that an target fabric module's endpoints containg active struct se_port(s) will have to be released via target_core_fabric_configfs.c: target_fabric_port_unlink() via: unlink /sys/kernel/config/target/$FABRIC_MOD/$ENDPOINT/tpgt_$TPGT/lun/lun_$LUN_ID/<symlink> before rmdir release of struct se_device in target_core_configfs.c: target_core_drop_subdev() -> se_free_virtual_device() can happen via: rmdir /sys/kernel/config/target/core/$HBA/* to release struct se_subsystem_dev in target_core_drop_subdev() Reported-by:

This patch converts the target_core_store_dev_enable() -> struct se_subsystem_api->create_virtdevice() call to return proper ERR_PTR values back up to configfs logic during backend dependent struct se_device ENABLE exception conditions. Along with the change to target_core_configfs.c, this includes converting IBLOCK, FILEIO, pSCSI, and RAMDISK_* backend subsystem plugins to obtain upper level PTR_ERR return codes (where available), and return via ERR_PTR during a *_create_virtdev() failure.

match_strdup() dynamically allocates memory and it is the responsabillity of the caller to free that memory. The following three cases: drivers/target/target_core_file.c:fd_set_configfs_dev_params() drivers/target/target_core_iblock.c:iblock_set_configfs_dev_params() drivers/target/target_core_configfs.c:target_core_dev_pr_store_attr_res_aptpl_metadata() should be kfree()'ing the allocated memory once it is no longer needed. It also makes sure to return -ENOMEM if the memory allocation in match_strdup() should fail. For target_core_configfs.c, this patch adds kfree()'s around Opt_initiator_fabric, Opt_initiator_node, Opt_initiator_sid, Opt_sa_res_key, Opt_target_fabric, and Opt_target_node for the Persistent Reservations Activate Persistence across Target Power Loss (APTPL=1) token parsing.

During device discovery, scsi mid layer sends INQUIRY command to LUN 0. If the LUN 0 is not mapped to host, it creates a temporary scsi_device with LUN id 0 and sends REPORT_LUNS command to it. After the REPORT_LUNS succeeds, it walks through the LUN table and adds each LUN found to sysfs. At the end of REPORT_LUNS lun table scan, it will delete the temporary scsi_device of LUN 0. When scsi devices are added to sysfs, it calls add_dev function of all the registered class interfaces. If ses driver has been registered, ses_intf_add() of ses module will be called. This function calls scsi_device_enclosure() to check the inquiry data for EncServ bit. Since inquiry was not allocated for temporary LUN 0 scsi_device, it will cause NULL pointer exception. To fix the problem, sdev->inquiry is checked for NULL before reading it. Signed-off-by:

enclosure page 7 gives us the "pretty" names of the enclosure slots. Without a page 7, we can still use the enclosure code as long as we make up numeric names for the slots. Unfortunately, the current code fails to add any devices because the check for page 10 is in the wrong place if we have no page 7. Fix it so that devices show up even if the enclosure has no page 7.

A conflict between 52c50567 ("mm: swap: unlock swapfile inode mutex before closing file on bad swapfiles") and 83ef99be ("sys_swapon: remove did_down variable") caused a double unlock of the inode mutex (once in bad_swap: before the filp_close, once at the end just before returning). The patch which added the extra unlock cleared did_down to avoid unlocking twice, but the other patch removed the did_down variable. To fix, set inode to NULL after the first unlock, since it will be used after that point only for the final unlock. While checking this patch, I found a path which could unlock without locking, in case the same inode was added as a swapfile twice. To fix, move the setting of the inode variable further down, to just before claim_swapfile, which will lock the inode before doing anything else.
