1. After attr was found in the attrs_list, it is inserted again back into the same list. As a result the list becomes corrupted.
The bug can be reproduced for example by the following sequence:
$ echo add_attribute IncomingUser user secret111111 > /sys/kernel/scst_tgt/targets/iscsi/mgmt
$ echo user secret222222 > /sys/kernel/scst_tgt/targets/iscsi/IncomingUser
$ echo del_attribute IncomingUser user > /sys/kernel/scst_tgt/targets/iscsi/mgmt
$ iscsiadm -m discovery -t st -p 127.0.0.1
Discovery fails and in syslog there is a message
Oct 2 18:58:37 vsa-00000611 iscsi-scstd: [1059] cmnd_exec_login:940: ERROR: Authentication of initiator iqn.2011-04.com.zadarastorage:1553:vc-0 failed
2. Small memory leak in error recovery path.

This is the SCST development repository. It contains not a single project SCST as one can think, but a number of them, which are divided as the following: 1. SCST core in scst/ subdirectory 2. Administration utility for SCST core scstadmin in scstadmin/ 3. Target drivers in own subdirectories qla2x00t/, iscsi-scst/, etc. 4. User space programs in usr/ subdirectory, like fileio_tgt. 5. Some various docs in doc/ subdirectory. Those subprojects are in most cases independent from each other, although some of them depend from the SCST core. They put in the single repository only to simplify their development, they are released independently. Thus, use "make all" only if you really need to build everything. Otherwise build only what you need, like for iSCSI-SCST: make scst scst_install iscsi iscsi_install For more information about each subproject see their README files.
