2013-11-21iscsi-target: chap auth shouldn't match username with trailing garbageEric Seppanen1-1/+4
In iSCSI negotiations with initiator CHAP enabled, usernames with trailing garbage are permitted, because the string comparison only checks the strlen of the configured username. e.g. "usernameXXXXX" will be permitted to match "username". Just check one more byte so the trailing null char is also matched.

2013-11-21iscsi-target: fix extract_param to handle buffer length corner caseEric Seppanen1-1/+1
extract_param() is called with max_length set to the total size of the output buffer. It's not safe to allow a parameter length equal to the buffer size as the terminating null would be written one byte past the end of the output buffer.

2013-11-20iscsi-target: Do not reject non-immediate CmdSNs exceeding MaxCmdSNNicholas Bellinger2-8/+11
This patch changes iscsit_sequence_cmd() logic to no longer reject non-immediate CmdSNs that exceed MaxCmdSN with a protocol error, but instead silently ignore them. This is done to correctly follow RFC-3720 Section 3.2.2.1: For non-immediate commands, the CmdSN field can take any value from ExpCmdSN to MaxCmdSN inclusive. The target MUST silently ignore any non-immediate command outside of this range or non- immediate duplicates within the range.

This patch converts a handful of iscsi_session statistics to type atomic_long_t, instead of using iscsi_session->session_stats_lock when incrementing these values. More importantly, go ahead and drop the spinlock usage within iscsit_setup_scsi_cmd(), iscsit_check_dataout_hdr(), iscsit_send_datain(), and iscsit_build_rsp_pdu() fast-path code.

2013-11-14target: Fix delayed Task Aborted Status (TAS) handling bugNicholas Bellinger1-0/+2
This patch fixes a bug in delayed Task Aborted Status (TAS) handling, where transport_send_task_abort() was not returning for the case when the se_tfo->write_pending() callback indicated that last fabric specific WRITE PDU had not yet been received. It also adds an explicit cmd->scsi_status = SAM_STAT_TASK_ABORTED assignment within transport_check_aborted_status() to avoid the case where se_tfo->queue_status() is called when the SAM_STAT_TASK_ABORTED assignment + ->queue_status() in transport_send_task_abort() does not occur once SCF_SENT_DELAYED_TAS has been set.

2013-11-14iscsi-target: Reject unsupported multi PDU text command sequenceNicholas Bellinger1-0/+7
This patch adds a check to reject text commands with F_BIT=0 || C_BIT=1, as multi PDU text command sequences are currently unsupported. This avoids the case where a text command received with F_BIT=0, was generating a text response with F_BIT=1 which is a protocol error according to RFC-3720 Section 10.11.1.

2013-11-13ib_isert: Avoid duplicate iscsit_increment_maxcmdsn callNicholas Bellinger1-5/+1
This patch avoids a duplicate iscsit_increment_maxcmdsn() call for ISER_IB_RDMA_WRITE within isert_map_rdma() + isert_reg_rdma_frwr(), which will already be occuring once during isert_put_datain() -> iscsit_build_rsp_pdu() operation. It also removes the local conn->stat_sn assignment + increment, and changes the third parameter to iscsit_build_rsp_pdu() to signal this should be done by iscsi_target_mode code.

2013-11-13iscsi-target: Fix mutex_trylock usage in iscsit_increment_maxcmdsnNicholas Bellinger2-5/+6
This patch fixes a >= v3.10 regression bug with mutex_trylock() usage within iscsit_increment_maxcmdsn(), that was originally added to allow for a special case where ->cmdsn_mutex was already held from the iscsit_execute_cmd() exception path for ib_isert. When !mutex_trylock() was occuring under contention during normal RX/TX process context codepaths, the bug was manifesting itself as the following protocol error: Received CmdSN: 0x000fcbb7 is greater than MaxCmdSN: 0x000fcbb6, protocol error. Received CmdSN: 0x000fcbb8 is greater than MaxCmdSN: 0x000fcbb6, protocol error. This patch simply avoids the direct ib_isert callback in lio_queue_status() for the special iscsi_execute_cmd() exception cases, that allows the problematic mutex_trylock() usage in iscsit_increment_maxcmdsn() to go away.

In addition to block size (already implemented), passing through alignment offset, logical-to-phys block exponent, I/O granularity and optimal I/O length will allow initiators to properly handle layout on LUNs with 4K block sizes. Tested with various weird values via scsi_debug module. One thing to look at with this patch is the new block limits values -- instead of granularity 1 optimal 8192, Lio will now be returning whatever the block device says, which may affect performance.

This patch changes isert_reg_rdma_frwr() to not use FRMR for single dma entry requests from small I/Os, in order to avoid the associated memory registration overhead.

Now with percpu refcounting for se_lun in place, go ahead and drop the legacy per se_cmd accounting for se_lun shutdown.

2013-11-08target: Add percpu refcounting for se_lun accessNicholas Bellinger6-18/+45
This patch adds percpu refcounting for se_lun access that allows the association of an se_lun + se_cmd in transport_lookup_cmd_lun() to occur without an extra list_head for tracking outstanding I/O during se_lun shutdown. This effectively changes se_lun shutdown logic to wait for outstanding I/O percpu references to complete in transport_lun_remove_cmd() using se_lun->lun_ref_comp, instead of explicitly draining the per se_lun command list and waiting for individual se_cmd descriptor processing to complete.

This patch changes iscsit_check_dataout_hdr() to no longer generate REJECTs for zero-length DataOUTs, and instead simply ignore these requests. This follows RFC-3720, Section 10.7.7. DataSegmentLength "This is the data payload length of a SCSI Data-In or SCSI Data-Out PDU. The sending of 0 length data segments should be avoided, but initiators and targets MUST be able to properly receive 0 length data segments."

2013-11-07ib_isert: Add support for completion interrupt coalescingNicholas Bellinger2-12/+57
This patch adds support for completion interrupt coalescing that allows only every ISERT_COMP_BATCH_COUNT (8) to set IB_SEND_SIGNALED, thus avoiding completion interrupts for every posted iser_tx_desc. The batch processing is done using a per isert_conn llist that once IB_SEND_SIGNALED has been set is saved to tx_desc->comp_llnode_batch, and completion processing of previously posted iser_tx_descs is done in a single shot from within isert_send_completion() code. Note this is only done for response PDUs from ISCSI_OP_SCSI_CMD, and all other control type of PDU responses will force an implicit batch drain to occur.

2013-09-29Revert "perf symbols: Demangle cloned functions"Ingo Molnar1-26/+1
This reverts commit de95ab53645a2f0015e0f68ee723f18dce2b8b51. Markus Trippelsdorf reported that this commit broke 'perf top': > I just see a gray screen with no text at all. Sometimes the > following error messages are printed: > > *** Error in `perf': invalid fastbin entry (free): 0x00000000029b18c0 > *** > *** Error in `perf': malloc(): memory corruption (fast): 0x0000000000ee0b10 *** While this code is fixable, the commit itself fails on several levels: - it should have been a separate helper function - why the heck does it do strchr() twice - it casts a const char * over into char * - sloppy style - it's not even a regression fix! So lets revert it and re-try the patch in v3.13.
