From e9da4d7f731dafc2b93ce7b31aa09c4d935ef978 Mon Sep 17 00:00:00 2001 From: Boaz Harrosh Date: Sun, 19 Apr 2009 19:17:54 +0300 Subject: [SCSI] libosd: OSD2r05: on-the-wire changes for latest OSD2 revision 5. 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 Signed-off-by: James Bottomley --- include/scsi/osd_protocol.h | 23 +++++++++++++---------- 1 file changed, 13 insertions(+), 10 deletions(-) (limited to 'include/scsi') diff --git a/include/scsi/osd_protocol.h b/include/scsi/osd_protocol.h index bbeceeb0e553..62b2ab8c69d4 100644 --- a/include/scsi/osd_protocol.h +++ b/include/scsi/osd_protocol.h @@ -24,18 +24,17 @@ enum { OSDv1_ADDITIONAL_CDB_LENGTH = 192, OSDv1_TOTAL_CDB_LEN = OSDv1_ADDITIONAL_CDB_LENGTH + 8, OSDv1_CAP_LEN = 80, + /* Latest supported version */ -/* OSD_ADDITIONAL_CDB_LENGTH = 216,*/ + OSDv2_ADDITIONAL_CDB_LENGTH = 228, OSD_ADDITIONAL_CDB_LENGTH = - OSDv1_ADDITIONAL_CDB_LENGTH, /* FIXME: Pete rev-001 sup */ + OSDv2_ADDITIONAL_CDB_LENGTH, OSD_TOTAL_CDB_LEN = OSD_ADDITIONAL_CDB_LENGTH + 8, -/* OSD_CAP_LEN = 104,*/ - OSD_CAP_LEN = OSDv1_CAP_LEN,/* FIXME: Pete rev-001 sup */ + OSD_CAP_LEN = 104, OSD_SYSTEMID_LEN = 20, OSDv1_CRYPTO_KEYID_SIZE = 20, - /*FIXME: OSDv2_CRYPTO_KEYID_SIZE = 32,*/ - OSDv2_CRYPTO_KEYID_SIZE = 20, + OSDv2_CRYPTO_KEYID_SIZE = 32, OSD_CRYPTO_KEYID_SIZE = OSDv2_CRYPTO_KEYID_SIZE, OSD_CRYPTO_SEED_SIZE = 4, OSD_CRYPTO_NONCE_SIZE = 12, @@ -166,7 +165,11 @@ struct osd_cdb_head { /* called allocation_length in some commands */ /*32*/ __be64 length; /*40*/ __be64 start_address; -/*48*/ __be32 list_identifier;/* Rarely used */ + union { +/*48*/ __be32 list_identifier;/* Rarely used */ + /* OSD2r05 5.2.5 CDB continuation length */ +/*48*/ __be32 cdb_continuation_length; + }; } __packed v2; }; /*52*/ union { /* selected attributes mode Page/List/Single */ @@ -331,6 +334,7 @@ struct osdv1_attributes_list_element { struct osdv2_attributes_list_element { __be32 attr_page; __be32 attr_id; + u8 reserved[6]; __be16 attr_bytes; /* valid bytes at attr_val without padding */ u8 attr_val[0]; } __packed; @@ -520,7 +524,7 @@ enum osd_capability_bit_masks { OSD_SEC_CAP_NONE1 = BIT(8), OSD_SEC_CAP_NONE2 = BIT(9), - OSD_SEC_CAP_NONE3 = BIT(10), + OSD_SEC_GBL_REM = BIT(10), /*v2 only*/ OSD_SEC_CAP_QUERY = BIT(11), /*v2 only*/ OSD_SEC_CAP_M_OBJECT = BIT(12), /*v2 only*/ OSD_SEC_CAP_POL_SEC = BIT(13), @@ -595,8 +599,7 @@ struct osdv1_capability { struct osd_capability { struct osd_capability_head h; -/* struct osd_cap_object_descriptor od;*/ - struct osdv1_cap_object_descriptor od; /* FIXME: Pete rev-001 sup */ + struct osd_cap_object_descriptor od; } __packed; /** -- cgit v1.2.1
