2009-10-14firewire: sbp2: provide fallback if mgt_ORB_timeout is missingStefan Richter
The Unit_Characteristics entry of an SBP-2 unit directory is not mandatory as far as I can tell. If it is missing, we would probably fail to log in into the target because firewire-sbp2 would not wait for status after it sent the login request. The fix moves the cleanup of tgt->mgt_orb_timeout into a place where it is executed exactly once before login, rather than 0..n times depending on the target's config ROM. With targets with one or more Unit_Characteristics entries, the result is the same as before. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

The inquiry delay does more harm than good in tests on a recent kernel. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
2009-09-12firewire: sbp2: fix status receptionStefan Richter
Per SBP-2 clause 5.3, a target shall store 8...32 bytes of status information. Trailing zeros after the first 8 bytes don't need to be stored, they are implicit. Fix the status write handler to clear all unwritten status data. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

2009-09-05firewire: sbp2: fix freeing of unallocated memoryStefan Richter
If a target writes invalid status (typically status of a command that already timed out), firewire-sbp2 attempts to put away an ORB that doesn't exist. https://bugzilla.redhat.com/show_bug.cgi?id=519772 Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

Increase the command ORB data structure to transport up to 16 bytes long CDBs (instead of 12 bytes), and tell the SCSI mid layer about it. This is notably necessary for READ CAPACITY(16) and friends, i.e. support of large disks. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

2009-06-06firewire: add parent-of-unit accessorStefan Richter
Retrieval of an fw_unit's parent is a common pattern in high-level code. Wrap it up as device = fw_parent_device(unit). Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
2009-06-05firewire: rename source filesStefan Richter
The source files of firewire-core, firewire-ohci, firewire-sbp2, i.e. "drivers/firewire/fw-*.c" are renamed to "drivers/firewire/core-*.c", "drivers/firewire/ohci.c", "drivers/firewire/sbp2.c". The old fw- prefix was redundant to the directory name. The new core- prefix distinguishes the files according to which driver they belong to. This change comes a little late, but still before further firewire drivers are added as anticipated RSN. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
