2009-12-04[SCSI] osd_protocol.h: Add missing #includeMartin Michlmayr
include/scsi/osd_protocol.h uses ALIGN() without an #include <linux/kernel.h>, leading to: | include/scsi/osd_protocol.h:362: error: implicit declaration of function 'ALIGN' Signed-off-by: Martin Michlmayr <tbm@cyrius.com> Signed-off-by: Boaz Harrosh <bharrosh@panasas.com> Cc: Stable Tree <stable@kernel.org> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
2009-06-10[SCSI] libosd: OSD2r05: Additional command enumsBoaz Harrosh
Add all constant definitions of new OSD commands added in revision 4 & 5. Mainly for creating snapshots and clones. Signed-off-by: Boaz Harrosh <bharrosh@panasas.com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
2009-04-27[SCSI] libosd: OSD2r05: on-the-wire changes for latest OSD2 revision 5.Boaz Harrosh
OSC's OSD2 target: [git clone git://git.open-osd.org/osc-osd/ master] (Initiator code prior to this patch must use: "git checkout CDB_VER_OSD2r01" in the target tree above) This is a summery of the wire changes: * OSDv2_ADDITIONAL_CDB_LENGTH == 192 => 228 (Total CDB is now 236 bytes) * Attributes List Element Header grew, so attribute values are 8 bytes aligned. * Cryptographic keys and signatures are 20 => 32 * Few new definitions. (Still missing new standard definitions attribute values, these do not change wire format and will be added later when needed) Signed-off-by: Boaz Harrosh <bharrosh@panasas.com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
2009-04-27[SCSI] libosd: OSD2r05: OSD_CRYPTO_KEYID_SIZE will grow 20 => 32 bytesBoaz Harrosh
In OSD2r04 draft, cryptographic key size changed to 32 bytes from OSD1's 20 bytes. This causes a couple of on-the-wire structures to change, including the CDB. In this patch the OSD1/OSD2 handling is separated out in regard to affected structures, but on-the-wire is still the same. All on the wire changes will be submitted in one patch for bisect-ability.

2009-04-27[SCSI] libosd: OSD2r05: Prepare for rev5 attribute list changesBoaz Harrosh
In OSD2r05 draft each attribute list element header was changed so attribute-value would be 8 bytes aligned. In OSD2r01-r04 it was aligned on 2 bytes. (This is because in OSD2r01 the complete element was 8 bytes padded at end but the header was not adjusted and caused permanent miss-alignment.) OSD1 elements are not padded and might be or might not be aligned. OSD1 is still supported. In this code we do all the code re-factoring to separate OSD1/OSD2 differences but do not change actual wire format. All wire format changes will happen in one patch later, for bisect-ability.

2009-03-12[SCSI] libosd: OSD version 2 SupportBoaz Harrosh
Add support for OSD2 at run time. It is now possible to run with both OSDv1 and OSDv2 targets at the same time. The actual detection should be preformed by the security manager, as the version is encoded in the capability structure.

2009-03-12[SCSI] libosd: OSDv1 HeadersBoaz Harrosh
Headers only patch. osd_protocol.h Contains a C-fied definition of the T10 OSD standard osd_types.h Contains CPU order common used types osd_initiator.h API definition of the osd_initiator library osd_sec.h Contains High level API for the security manager.
