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. diff --git a/release_notes/srptools_release_notes.txt b/release_notes/srptools_release_notes.txt new file mode 100644 index 0000000..22bed7b --- /dev/null +++ b/release_notes/srptools_release_notes.txt @@ -0,0 +1,72 @@ + 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. + + +=========== +Source Code +=========== + +See also https://www.openfabrics.org/downloads/srptools/. -- 2.41.0
