+ Open Fabrics Enterprise Distribution (OFED)
+ ib_srp Release Notes
+ May 2014
+
+========
+Overview
+========
+
+The ib_srp kernel driver is a SCSI low-level initiator driver (LLD). This
+means that this kernel driver makes communication via the SCSI protocol
with
+an SRP target system possible. The version of the SRP initiator included in
+OFED 3.12 is derived from the upstream v3.12 Linux kernel SRP initiator
driver
+and has been ported to RHEL 6 and SLES 11. Lockless operation is enabled in
+combination with RHEL 6.2 and later, with SLES 11 and also with upstream
+kernel v2.6.37 and later but not with RHEL 6.0 nor with RHEL 6.1. For more
+information about lockless dispatching of SCSI commands, see also the
RHEL 6.2
+release notes
+(https://access.redhat.com/site/documentation/en-US/Red_Hat_Enterprise_Linux/6/html-single/6.2_Release_Notes/).
+
+
+=========
+Changelog
+=========
+
+OFED 3.12
+.........
+
+- A new sysfs attribute has been added that allows to disconnect the
+ initiator from a target port
(/sys/class/srp_remote_ports/${port}/delete).
+- Robustness of the driver with regard to cable pulling has been improved.
+
+
+OFED 3.5
+........
+
+The SRP initiator driver in OFED 3.5 was based on the ib_srp driver in the
+upstream Linux 3.5 kernel.

+ Open Fabrics Enterprise Distribution (OFED)
+ srptools Release Notes
+ May 2014
+
+========
+Overview
+========
+
+The srptools package contains tools for discovering SRP target ports in an
+InfiniBand network. The best known software component in this package is
+srp_daemon, a process that runs in the background, periodically scans a
fabric
+for SRP target ports and makes the SRP initiator kernel driver (ib_srp)
log in
+to the SRP target ports enabled in the srp_daemon.conf configuration file.
+
+
+=========
+Changelog
+=========
+
+Version 1.0.2 (February 20, 2014)
+.................................
+
+- Added support for specifying tl_retry_count in srp_daemon.conf. Changed
+ default behavior for tl_retry_timeout parameter from setting it to 2 into
+ leaving it at its default value (7). This makes srp_daemon again
compatible
+ with the SRP initiator driver from kernel 3.12 and before.
+
+Version 1.0.1 (February 4, 2014)
+................................
+
+- Make process uniqueness check work.
+- Unsubscribe from subnet manager for traps before exiting.
+- Added support for the comp_vector and queue_size configuration file
options.
+
+Version 1.0.0 (October 1, 2012)
+...............................
+
+- srp_daemon keeps working even if the LID changes of the port it is
using to
+ scan the fabric or if a P_Key change occurs.
+- Added P_Key support to srp_daemon and ibsrpdm.
+- Fixed month in srp_daemon.log (OFED bug #2281). srp_daemon now uses
syslog
+ and logrotate for logging.
+- srp_daemon is now only started for InfiniBand ports. It is no longer
+ attempted to start srp_daemon on Ethernet ports.
+- Added support for specifying the tl_retry_count parameter. By default use
+ tl_retry_count=2.
+- Allow srp_daemon to be started without configuration file.
+- Fixed a memory leak in srp_daemon that was triggered once during
every fabric
+ rescan.
+- Reduced memory consumption of the srp_daemon process.
+- MAD transaction ID 0 is skipped after 2**32 rescans.
+- Installation: SRPHA_ENABLE=no / SRP_DAEMON_ENABLE=no is only added to
+ /etc/infiniband/openibd.conf if these variables did not yet exist in that
+ file.
+- Changed range of the srp_daemon and ibsrpdm exit codes from 0..127
into 0..1.
+- Changed ibsrpdm such that it uses the new umad P_Key ABI. Running ibsrpdm
+ does no longer cause a warning to be logged ("user_mad: process
ibsrpdm did
+ not enable P_Key index support / user_mad:
+ Documentation/infiniband/user_mad.txt has info on the new ABI").
+- Fixed spelling of several help texts and diagnostic messages.
+
+Version 0.0.4 (August 30, 2009)
+...............................
+
+This is the version that was included in previous OFED versions, e.g.
OFED 3.5.
