Very similar to how it went with local_sockaddr. It was embedded in iscsi_login_stats so some changes there, and we needed to copy in a sockaddr_storage comparison function. Hopefully the kernel will get a standard one soon, our implementation makes the 3rd. isert_set_conn_info() became much smaller. IPV6_ADDRESS_SPACE define goes away, had to modify a call to in6_pton(), can just use -1 since we are sure string is null-terminated. Signed-off-by:

This is a more natural format that lets us format it with the appropriate printk specifier as needed. This also lets us handle v4-mapped ipv6 addresses a little more nicely, by storing the addr as an actual v4 sockaddr in conn->local_sockaddr. Finally, we no longer need to maintain variables for port, since this is contained in sockaddr. Remove iscsi_np.np_port and iscsi_conn.local_port. Signed-off-by:

Revert commit 1997e625, which causes double brackets on ipv6 inaddr_any addresses. Since we have np_sockaddr, if we need a textual representation we can use "%pISc". Change iscsit_add_network_portal() and iscsit_add_np() signatures to remove *ip_str parameter. Fix and extend some comments earlier in the function. Tested to work for :: and ::1 via iscsiadm, previously :: failed, see https://bugzilla.redhat.com/show_bug.cgi?id=1249107 . CC: stable@vger.kernel.org Signed-off-by:

In a performance profile, taking a mutex in iscsit_increment_maxcmdsn() shows up very high. However taking a mutex around "sess->max_cmd_sn += 1" seems pretty silly: we're not serializing against other contexts in any useful way. I did a quick audit and there don't appear to be any other places that use max_cmd_sn within the mutex more than once, so this lock can't be providing any useful serialization.

This patch adds a new tpg_enabled_sendtargets configfs attribute to allow in-band sendtargets discovery information to include target-portal-groups (TPGs) in !TPG_STATE_ACTIVE state. This functionality is useful for clustered iSCSI targets, where TPGTs handled on remote cluster nodes should be advertised in the SendTargets response. By default, this new attribute retains the default behaviour of existing code which to ignore portal-groups in !TPG_STATE_ACTIVE state. Signed-off-by:

It's not necessarily a fatal error if a command with a data-out phase has a data length that differs from the transport data length (e.g. PERSISTENT RESERVE OUT might have a parameter list length in the CDB that's smaller than the FC_DL field), so allow these commands.

Current implementation assumes that all the buffers of an IO are linked with a single SG list, which is OK because target-core is only allocating a contigious scatterlist region. However, this assumption is wrong for se_cmd descriptors that want to use chaining across multiple SGL regions. Fix this up by using proper SGL accessors for digest payload computation.

Commit 835a6a2f ("Bluetooth: Stop sabotaging list poisoning") thought that the code was sabotaging the list poisoning when NULL'ing out the list pointers and removed it. But what was going on was that the bluetooth code was using NULL pointers for the list as a way to mark it empty, and that commit just broke it (and replaced the test with NULL with a "list_empty()" test on a uninitialized list instead, breaking things even further). So fix it all up to use the regular and real list_empty() handling (which does not use NULL, but a pointer to itself), also making sure to initialize the list properly (the previous NULL case was initialized implicitly by the session being allocated with kzalloc()) This is a combination of patches by Marcel Holtmann and Tedd Ho-Jeong An. [ I would normally expect to get this through the bt tree, but I'm going to release -rc1, so I'm just committing this directly - Linus ] Reported-and-tested-by:

Pull SCSI target updates from Nicholas Bellinger: "It's been a busy development cycle for target-core in a number of different areas. The fabric API usage for se_node_acl allocation is now within target-core code, dropping the external API callers for all fabric drivers tree-wide. There is a new conversion to RCU hlists for se_node_acl and se_portal_group LUN mappings, that turns fast-past LUN lookup into a completely lockless code-path. It also removes the original hard-coded limitation of 256 LUNs per fabric endpoint. The configfs attributes for backends can now be shared between core and driver code, allowing existing drivers to use common code while still allowing flexibility for new backend provided attributes. The highlights include: - Merge sbc_verify_dif_* into common code (sagi) - Remove iscsi-target support for obsolete IFMarker/OFMarker (Christophe Vu-Brugier) - Add bidi support in target/user backend (ilias + vangelis + agover) - Move se_node_acl allocation into target-core code (hch) - Add crc_t10dif_update common helper (akinobu + mkp) - Handle target-core odd SGL mapping for data transfer memory (akinobu) - Move transport ID handling into target-core (hch) - Move task tag into struct se_cmd + support 64-bit tags (bart) - Convert se_node_acl->device_list[] to RCU hlist (nab + hch + paulmck) - Convert se_portal_group->tpg_lun_list[] to RCU hlist (nab + hch + paulmck) - Simplify target backend driver registration (hch) - Consolidate + simplify target backend attribute implementations (hch + nab) - Subsume se_port + t10_alua_tg_pt_gp_member into se_lun (hch) - Drop lun_sep_lock for se_lun->lun_se_dev RCU usage (hch + nab) - Drop unnecessary core_tpg_register TFO parameter (nab) - Use 64-bit LUNs tree-wide (hannes) - Drop left-over TARGET_MAX_LUNS_PER_TRANSPORT limit (hannes)" * 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending: (76 commits) target: Bump core version to v5.0 target: remove target_core_configfs.h target: remove unused TARGET_CORE_CONFIG_ROOT define target: consolidate version defines target: implement WRITE_SAME with UNMAP bit using ->execute_unmap target: simplify UNMAP handling target: replace se_cmd->execute_rw with a protocol_data field target/user: Fix inconsistent kmap_atomic/kunmap_atomic target: Send UA when changing LUN inventory target: Send UA upon LUN RESET tmr completion target: Send UA on ALUA target port group change target: Convert se_lun->lun_deve_lock to normal spinlock target: use 'se_dev_entry' when allocating UAs target: Remove 'ua_nacl' pointer from se_ua structure target_core_alua: Correct UA handling when switching states xen-scsiback: Fix compile warning for 64-bit LUN target: Remove TARGET_MAX_LUNS_PER_TRANSPORT target: use 64-bit LUNs target: Drop duplicate + unused se_dev_check_wce target: Drop unnecessary core_tpg_register TFO parameter ...
