Version 2.2.0 (not yet released)
|
|
-------------
|
|
Changes compared to version 2.1.0:
|
|
- Changed default value of the kernel module parameter srp_max_req_size from
|
|
2116 into 4148. That last value corresponds to a table size of 255 elements.
|
|
- "make debug2release" etc. now also affects ib_srpt.
|
|
- Slightly reduced the number of IB interrupts caused by SRP traffic.
|
|
- Fixed a bug that could cause unloading ib_srpt to take up to 120s.
|
|
- Fixed a crash in the I/O context ring allocation that was triggered when
|
|
trying to allocate more memory than available.

Version 1.0.1 (released on April 28, 2009)
|
|
-------------
|
|
|
|
Changes compared to version 1.0.0:
|
|
- Performance has been improved. I/O requests are now handled in soft IRQ
|
|
context instead of on a separate thread, which drastically reduces the
|
|
number of context switches needed for processing I/O (r594).
|
|
- Added support for building SCST-SRPT against the OFED InfiniBand drivers
|
|
(r814:838).
|
|
- Compiles now without further patches on RHEL 5.x / CentOS 5.x systems (r638).
|
|
- Compiles now against 2.6.26 and later kernels (r516).
|
|
- Fixed incorrect SCST state used on error path (r557).
|
|
- Fixed memory leak triggered by rejecting SRP login requests (r800).
|
|
- Fixed kernel oops triggered by reception of an asynchronous InfiniBand event.
|
|
Asynchronous events are triggered by e.g. resetting an InfiniBand switch or
|
|
reconnecting an InfiniBand cable (r878:880). The call stack of the oops is
|
|
as follows:
|
|
queue_work+0x1a/0x20
|
|
schedule_work+0x16/0x20
|
|
srpt_event_handler+0xda/0xe0 [ib_srpt]
|
|
ib_dispatch_event+0x39/0x70 [ib_core]
|
|
mlx4_ib_process_mad+0x3e6/0x430 [mlx4_ib]
|
|
ib_post_send_mad+0x374/0x6f0 [ib_mad]
|
|
? futex_wake+0x105/0x120
|
|
ib_umad_write+0x4a8/0x5c0 [ib_umad]
|
|
vfs_write+0xcb/0x170
|
|
sys_write+0x50/0x90
|
|
system_call_fastpath+0x16/0x1b
|
|
- The login information for HCA's with more than two ports is now displayed
|
|
correctly. Note: no such devices exist yet (r799).
|
|
|
|
|
|
Version 1.0.0 (released on July 14, 2008)
|
|
-------------
|
|
Almost identical to trunk r440 (only the variables SCST_DIR and EXTRA_CFLAGS
|
|
in the Makefiles are different from trunk r440).
