2020-03-11scsi: iscsi: Add support for asynchronous iSCSI session destructionFrank Mayhar1-0/+38
iSCSI session destruction can be arbitrarily slow, since it might require network operations and serialization inside the SCSI layer. This patch adds a new user event to trigger the destruction work asynchronously, releasing the rx_queue_mutex as soon as the operation is queued and before it is performed. This change allows other operations to run in other sessions in the meantime, removing one of the major iSCSI bottlenecks for us. To prevent the session from being used after the destruction request, we remove it immediately from the sesslist. This simplifies the locking required during the asynchronous removal.

2020-03-11scsi: ibmvfc: Avoid loss of all paths during SVC node rebootBrian King2-37/+173
When an SVC node goes down as part of a node reboot, its WWPNs are moved to the remaining node. When the node is back online, its WWPNs are moved back. The result is that the WWPN moves from one NPort_ID to another, then back again. The ibmvfc driver was forcing the old port to be removed, but not sending an implicit logout. When the WWPN showed up at the new location, the PLOGI failed as there was already a login established for the old scsi id. The patch below fixes this by ensuring we always send an implicit logout for any scsi id associated with an rport prior to calling fc_remote_port_delete.

2020-03-11scsi: Replace zero-length array with flexible-array memberGustavo A. R. Silva9-12/+12
The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.

Replace the open-coded implementation for reading the PCIe DSN with pci_get_dsn(). The original code used a for-loop that looped over each of the 8 bytes and copied them into a temporary buffer. pci_get_dsn() uses two calls to pci_read_config_dword, and correctly bitwise ORs them into a u64.

There is no need to wait for outstanding write commands on synchronize cache; the block layer is responsible for I/O scheduling, no need to out-guess it in the driver layer.

2020-02-28scsi: dpt_i2o: use scsi_host_complete_all_commands() to abort outstanding commandsHannes Reinecke2-20/+1
Rather than traversing all outstanding commands manually, use the scsi_host_complete_all_commands() helper to terminate all commands during reset. With that we can drop the cmd_list usage from the midlayer.

Rename the badly named function into adpt_i2o_scsi_complete(), and make it a void function as the return value is never used. This also fixes a potential use-after-free as the return value might be evaluated from the command result after the command has been freed.
