  • 596fee74a4 Don't try and stop a kernel thread that hasn't started- this will fix some reported oopses. Dotan Barak 2009-09-08 01:45:52 +00:00
  • 72d038f1b6 If we're running newer than 3.0.16 firmware and are in target mode, tell the firmware to not automatically issue a PRLI after a PLOGI. This should solve the problem of being in N-port topology where we have to issue a PLOGI which by default is followed by a PRLI, which makes us an illegal target. Dotan Barak 2009-09-08 01:40:39 +00:00

  • 28cb02f78b Minor documentation updates. Bart Van Assche 2009-08-15 13:54:36 +00:00
  • 1e1b800f8b - Changed the identification string displayed by the ibsrpdm tool from "Mellanox OFED SRP target" to "SCST SRP target" to reflect that this version of the SRP target is distributed through the SCST project. - Added kernel parameter use_port_guid_in_session_name that allows to use the original session naming scheme of the SRP target. This should make it again possible to connect to a multiport SRP target by masking out redundant paths on the target. - Made sure that whenever a login is rejected that a kernel message is generated (printk()) such that this information ends up in /var/log/messages. Bart Van Assche 2009-08-15 13:48:12 +00:00
  • 6f191159e9 Added more comments. Bart Van Assche 2009-08-15 13:33:24 +00:00

Bart Van Assche 2009-08-14 18:26:58 +00:00

  • 64f93b6add - Implemented kernel module parameter one_guid_per_ioc. Setting this parameter to true should make it possible to connect from a WinOF initiator to an SRP target when there is more than one IB path between initiator and target. - Renamed mellanox_ioc_guid into global_ioc_guid.

  • 3d227b8f73 - Added consistency checking for the SRPT command state management introduced in r1026. - Removed WARN_ON() statements that could trigger a warning when nothing was wrong because these were reading uninitialized memory. These statements were introduced in r1026. The call stack of the warning logged in the kernel log is as follows: <IRQ> [<ffffffffa057f578>] ? srpt_handle_new_iu+0x818/0xaf0 [ib_srpt] [<ffffffff80243f18>] warn_slowpath_common+0x78/0xd0 [<ffffffff80243f7f>] warn_slowpath_null+0xf/0x20 [<ffffffffa057f578>] srpt_handle_new_iu+0x818/0xaf0 [ib_srpt] [<ffffffffa057f9ab>] srpt_completion+0x15b/0x230 [ib_srpt] [<ffffffffa04351f2>] mlx4_ib_cq_comp+0x12/0x20 [mlx4_ib] [<ffffffffa01eb1aa>] mlx4_cq_completion+0x3a/0x80 [mlx4_core] [<ffffffffa01ec475>] mlx4_eq_int+0x2a5/0x2e0 [mlx4_core] [<ffffffffa01ec59a>] mlx4_msi_x_interrupt+0x6a/0x90 [mlx4_core] [<ffffffff8027c0aa>] handle_IRQ_event+0x3a/0xf0 [<ffffffff8027dee1>] handle_edge_irq+0xc1/0x160 [<ffffffff8020ec3f>] handle_irq+0x1f/0x30 [<ffffffff8020e37a>] do_IRQ+0x6a/0xf0 [<ffffffff8020c7d3>] ret_from_intr+0x0/0xa <EOI> [<ffffffffa0012e52>] ? acpi_idle_enter_simple+0x159/0x187 [processor] [<ffffffffa0012e48>] ? acpi_idle_enter_simple+0x14f/0x187 [processor] [<ffffffff804323e5>] ? cpuidle_idle_call+0xa5/0x100 [<ffffffff8020b0a2>] ? cpu_idle+0x62/0xd0 [<ffffffff804be614>] ? rest_init+0x84/0x90 [<ffffffff8067ecc5>] ? start_kernel+0x35a/0x415 [<ffffffff8067e289>] ? x86_64_start_reservations+0x99/0xb9 [<ffffffff8067e389>] ? x86_64_start_kernel+0xe0/0xf2 Bart Van Assche 2009-08-10 09:57:30 +00:00
  • bbad4dfcaa - Fixed memory leak in srpt_handle_tsk_mgmt() error path. - Modified srpt_build_cmd_rsp() and srpt_build_tskmgmt_rsp() such that these two functions now return the number of bytes of the response PDU built. - Converted a printk() statement to TRACE_DBG(). Bart Van Assche 2009-08-08 15:02:19 +00:00
  • 375a72b685 Added more comments. Bart Van Assche 2009-08-08 14:59:28 +00:00

  • 7286d22319 Fixed data races on manipulation of the srpt_devices list by eliminating this list. Only the number of IB devices is relevant for the SRPT implementation. Introduced a new counter that tracks the number of IB devices. Bart Van Assche 2009-08-06 10:05:10 +00:00
  • e9feb2e818 - Refactoring: split srpt_ch_qp_rtr_rts() into two functions, namely srpt_ch_qp_rtr() and srpt_ch_qp_rts(). - Replaced dynamic memory allocation (kmalloc()/kfree()) in the aforementioned two functions by stack allocation. - Compiles again on pre-2.6.22 kernels (RHEL / CentOS systems). Bart Van Assche 2009-08-06 09:12:37 +00:00
  • 8ca3e36e99 - Fixed race conditions related to channel state manipulation. - Inlined srpt_disconnect_channel(). - Modified error handling coding style in srpt_cm_req_recv() to the usual kernel coding style: upon error, jump to the error handling code. - Added more comments. Bart Van Assche 2009-08-05 19:48:16 +00:00
  • 0e1890f3c7 Minor docs update Vladislav Bolkhovitin 2009-08-05 09:50:11 +00:00
  • 6dc8835e7e - Bug fix: if processing of any of the SRP task management functions by the SCST core fails (abort task, LUN reset, ...), an SRP_RSP PDU is now sent back to the initiator. - Added more debug tracing statements. - Improved readability of some parts of the source code. - Added more comments. - Partially reverted one hunk of r1003: while casting an unsigned 64-bit value to the type u64 and printing such values via %llx works fine on x86 systems, the same code triggers a compiler warning on PowerPC systems. So while r1003 changed some (unsigned long long) casts to (u64) casts, this revision changes these back to (unsigned long long) casts. Bart Van Assche 2009-08-04 18:45:46 +00:00
  • b06a932d2c Web updates Vladislav Bolkhovitin 2009-08-04 17:50:43 +00:00

  • 70110ec078 Fixed race conditions on RDMA channel manipulations found via source reading: - Added a second argument to srpt_find_channel() that specified whether or not the channel should be removed from the channel list if found. - Moved list_del() statement from the body of the srpt_release_channel() function to its callers. Bart Van Assche 2009-08-03 16:00:36 +00:00
  • 7234de012f Multiple cosmetic source code changes. Bart Van Assche 2009-08-03 15:06:00 +00:00
  • 47d7742f4e - Enabled the LUN reset task management function. - Changed return type of srpt_release_channel() from int to void because the return value did depend in a trivial way on the function arguments. Changed the return type of srpt_find_and_release_channel() and several of its callers also from int to void. Instead srpt_cm_handler() now directly sets its own return value. - Converted a list_for_each_entry_safe() into a list_for_each_entry() loop because no elements are added or deleted in the loop body. - Converted debug-printk() statements into TRACE_DBG(). - Changed indentation of one statement from 12 to 16 (was not reported by checkpatch). Bart Van Assche 2009-08-02 18:57:48 +00:00

  • ec9041654c Upgraded kernel versions 2.6.27.28 and 2.6.30.3 to 2.6.27.29 and 2.6.30.4 respectively. Bart Van Assche 2009-07-31 06:21:31 +00:00
  • 745a852fbe - Fixed a buffer overrun: a service entry name occupying 35 bytes was written into a buffer with a size of 32 bytes. Enlarged the buffer to 36 bytes. - Converted sprintf() calls to snprintf() calls. - Added more TRACE_ENTRY() / TRACE_EXIT() statements. Bart Van Assche 2009-07-30 12:48:06 +00:00
  • 57f4019ed5 Moved /sys/class/infiniband_srpt/trace_level to /proc/scsi_tgt/ib_srpt/trace_level such that the behavior of the ib_srpt target is consistent with that of other SCST drivers. Bart Van Assche 2009-07-30 08:32:23 +00:00

  • 3e18defd73 Should have been included in the previous commit (r988). Bart Van Assche 2009-07-29 18:14:41 +00:00
  • 5d67fefe37 - Fixed a race condition found via source reading: srpt_remove_one() did not wait until srpt_refresh_port_work() finished. This race condition could be triggered during module removal. - Added a kernel module parameter called "trace_flag" that allows to set the trace flags for the ib_srpt module before module initialization starts. - Added sysfs variable /sys/class/infiniband_srpt/trace_level that allows to display and to modify the enabled trace flags in a human-readable form. - Added several TRACE_ENTRY() / TRACE_EXIT() statements. - Added more comments.
