| * [SCSI] libiscsi: do not block session during logoutMike Christie2008-01-112-0/+3
| | | | | | | | | | | | | | | | | | There is not need to block the session during logout. Since we are going to fail the commands that were blocked just fail them immediately instead.

| * [SCSI] libiscsi, iscsi_tcp: iscsi pool cleanupOlaf Kirch2008-01-111-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | iscsi_pool_init simplified iscsi_pool_init currently has a lot of duplicate kfree() calls it does when some allocation fails. This patch simplifies the code a little by using iscsi_pool_free to tear down the pool in case of an error. iscsi_pool_init also returns a copy of the item array to the caller. Not all callers use this array, so we make it optional. Instead of allocating a second array and return that, allocate just one array, of twice the size. Update users of iscsi_pool_{init,free} This patch drops the (now useless) second argument to iscsi_pool_free, and updates all callers. It also removes the ctask->r2ts array, which was never used anyway. Since the items argument to iscsi_pool_init is now optional, we can pass NULL instead.

| * [SCSI] iscsi_tcp, libiscsi: initial AHS SupportBoaz Harrosh2008-01-112-3/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | at libiscsi generic code - currently code assumes a storage space of pdu header is allocated at llds ctask and is pointed to by iscsi_cmd_task->hdr. Here I add a hdr_max field pertaining to that storage, and an hdr_len that accumulates the current use of the pdu-header. - Add an iscsi_next_hdr() inline which returns the next free space to write new Header at. Also iscsi_next_hdr() is used to retrieve the address at which to write the header-digest. - Add iscsi_add_hdr(length). What the user do is calls iscsi_next_hdr() for address of the new header, than calls iscsi_add_hdr(length) with the size of the new header. iscsi_add_hdr() will check if space is available and update to the new size. length must be padded according to standard. - Add 2 padding inline helpers thanks to Olaf. Current patch does not use them but Following patches will. Also moved definition of ISCSI_PAD_LEN to iscsi_proto.h which had PAD_WORD_LEN that was never used anywhere. - Let iscsi_prep_scsi_cmd_pdu() signal an Error return since now it is possible that it will fail. - I was tired of yet again writing a "this is a digest" comment next to sizeof(__u32) so I defined a new ISCSI_DIGEST_SIZE. Now I don't need any comments. Changed all places that used sizeof(__u32) or "4" in connection to a digest. iscsi_tcp specific code - At struct iscsi_tcp_cmd_task allocate maximum space allowed in standard for all headers following the iscsi_cmd header. and mark it so in iscsi_tcp_session_create() - At iscsi_send_cmd_hdr() retrieve the correct headers size and write header digest at iscsi_next_hdr().

| * [SCSI] move single_lun flag from scsi_device to scsi_targetTony Battersby2008-01-111-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some SCSI tape medium changers that need the BLIST_SINGLELUN flag have the medium changer at one LUN and the tape drive at a different LUN. The inquiry string of the tape drive may be different from that of the medium changer. In order for single_lun to be effective, every scsi_device under a given scsi_target must have it set. This means that there needs to be a blacklist entry for BOTH the medium changer AND the tape drive, which is impractical because some medium changers may be paired with a variety of different tape drive models. It makes more sense to put the single_lun flag in scsi_target instead of scsi_device, which causes every device at a given target ID to inherit the single_lun flag from one LUN. This makes it possible to blacklist just the medium changer and not the tape drive.

As this represents the actual length of buffer available to the controller and the controller must be able to deal with short transfers for ATAPI commands which can transfer variable length, this shouldn't break any controllers while making problems like rounding-down and controllers choking up on odd transfer bytes much less likely.

This means that an ATA8 TCG drive is going to trigger 32bit I/O on some systems which will be funny. Anyway we need to sort this out ready for ATA8 so: - Reorder the ata.h header a bit so the ata_version function occurs early in it - Make dword_io check the ATA version - Add an ATA8 version checking TCG presence test While we are at it the current drafts have a flaw where it may not be possible to disable TCG features at boot (and opt out of the trusted model) as TCG intends because it relies on presence of a different optional feature (DCS). Handle this in software by refusing the TCG commands if libata.allow_tpm is not set. (We must make it possible as some environments such as proprietary VDR devices will doubtless want to use it to lock up content) Finally as with CPRM print a warning so that the user knows they may not be able to full access and use the device.

| * | | | IPoIB: improve IPv4/IPv6 to IB mcast mapping functionsRolf Manderscheid2008-01-252-8/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | An IPoIB subnet on an IB fabric that spans multiple IB subnets can't use link-local scope in multicast GIDs. The existing routines that map IP/IPv6 multicast addresses into IB link-level addresses hard-code the scope to link-local, and they also leave the partition key field uninitialised. This patch adds a parameter (the link-level broadcast address) to the mapping routines, allowing them to initialise both the scope and the P_Key appropriately, and fixes up the call sites. The next step will be to add a way to configure the scope for an IPoIB interface. Signed-off-by: Rolf Manderscheid <rvm@obsidianresearch.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>

Connection request events are reported on the event channel associated with the listen. When the connection is accepted, a new rdma_cm_id is created and automatically uses the listen event channel. This is suboptimal where the user only wants listen events on that channel. Additionally, it may be desirable to have events related to connection establishment use a different event channel than those related to already established connections. Allow the user to migrate an rdma_cm_id between event channels. All pending events associated with the rdma_cm_id are moved to the new event channel.
