| |
| Summary of changes in iSCSI-SCST between versions 1.0.0 and 1.0.1 |
| ----------------------------------------------------------------- |
| |
| - Support for variable length CDB added |
| |
| - Sending and receiving padding bytes as well as sesnse data |
| reimplemented to make it more reliable |
| |
| - Support for SCSI Async. Event Notifications added |
| |
| - Sessions and connections reinstatement reimplemented to be conforming |
| to iSCSI RFC |
| |
| - iscsi-scst-adm fixed |
| |
| - Removed artificial limitation of sg_tablesize. It isn't needed, |
| because the regular iSCSI negotiated MaxRecvDataSegmentLength-related |
| facilities do all the job pretty well. |
| |
| - Merge with IET r170-211: |
| |
| * Update MaxConnections documentation |
| |
| * Remove isns config description from man page |
| |
| * Check return values of chdir(), ftruncate() and write(), because |
| recent versions of the glibc insist on the return value being |
| checked by introducing __attribute__((warn_unused_result)) to these |
| functions. |
| |
| * Fix snprintf use in isns.c |
| |
| * Take \0-termination into account when passing strings to |
| isns_tlv_set() to solve incompatibility with MS iSNS 3.0 as IQN |
| length is multiple of 4 |
| |
| * Fix list corruption if SCST target registration fails |
| |
| * Register the target port actually used instead of the default iSCSI port. |
| |
| * Remove unused connection->pad |
| |
| * Refactor cmnd_execute() |
| |
| * Introduce min*/max*() and more list_* macros |
| |
| * Multipart PDU support for discovery sessions |
| |
| * Add support for Reject PDUs and make use of them in appropriate places. |
| |
| * Ignore SIGPIPE in iscsi-scstd |
| |
| * Allow removal of kernel target objects if the user space object does not exist |
| |
| * Use netlink_socket_release() to clean up netlink sockets correctly |
| (taking care of namespaces) |
| |
| * More scalable proc seq_file implementation |
| |
| * Segfault in ietd buffer overrun in dump_line |
| |
| * Add iscsi-scst-adm support to display list of CHAP accounts and their data |
| |
| * Fixed compilation on glibc 2.8 |
| |
| * Fix CHAP account handling bugs |
| |
| * Fix bugs in multi PDU handling code |
| |
| - Support for CentOS 5.2 added (Bart Van Assche) |
| |
| - Fixed NOP-Out with payload handling |
| |
| - Several minor iSCSI RFC violations fixed |
| |
| - Update for kernels up to 2.6.29 |
| |
| - Zero-copy feature, introduced by put_page_callback patch made |
| kernel compile time configurable via |
| CONFIG_TCP_ZERO_COPY_TRANSFER_COMPLETION_NOTIFICATION option. If you |
| upgrade from earlier versions, see the corresponding "[CAUTION]" |
| e-mail in scst-devel mailing list about possible compatibility |
| problems. |
| |
| - A lot of cleanups and minor fixes |
| |
| Summary of changes in iSCSI-SCST since it was IET |
| ------------------------------------------------- |
| |
| - Commands processing flow changed to work with SCST. Significant |
| cleanup was done. Modules and config files were renamed to allow to |
| run with IET on the same host. |
| |
| - In IET the iSCSI negotiation isn't fully iSCSI RFC confirmed: it doesn't |
| support ranges of values and, more important, violates RFC in case |
| when in the IET config file some value for some parameter is set and |
| a remote initiator doesn't initiate the negotiation for this |
| parameter or declare its value. According to RFC, in this case IET |
| shall use the RFC-specified default value, but it uses config file |
| specified one instead. Looks like the implementation confuses IET |
| config file default values and iSCSI RFC ones. The default values |
| handling was fixed. But support for ranges remains unfixed (see ToDo |
| file). |
| |
| - All shutdown/restart problems (resource leaks, hangups, etc.), especially |
| under load, were fixed. |
| |
| - Full duplex network IO implemented. |
| |
| - Threading model reimplemented. |
| |
| - Digests calculation made multi-threaded. |
| |
| - TX data digest errors handling iSCSI RFC violation was fixed. Another one |
| (SNACK handling) remains unfixed. |
| |
| - Ability to send data with sense in a single response added. |
| |
| - Ability to handle initiators misbehavior a bit improved: several BUG()'s |
| were replaced by the proper handling. However, there is a plenty of work in |
| this area left, IET is known to have a lot of weaknesses here. |
| |
| - Task management made more robust. Particularly, possible data |
| corruption scenarios were fixed. |
| |
| - Implemented SN based iSCSI IO flow control |
| |
| - Response data send timeout implemented: now if initiator doesn't |
| accept data for too long (30 sec), target closes connection |
| |
| - A lot of other bugfixes and code cleanups. |
