I spent the last couple of days rebasing my working set of kernel
patches from 2.6.22-rc5 to 2.6.24-rc6. I want to use the BSG
interface from userspace to submit variable-length bidirectional
SCSI commands to targets via iSCSI TCP.
Many thanks to all the work with scsi data accessors and iscsi that
makes this much easier, and to Boaz for continuing to maintain
patches. Here's what I needed to do to make it work.
Start with linus-2.6.24-rc6.
Merge scsi-misc.
Apply the following outstanding patches from Boaz:
bidi
scsi: scsi_data_buffer
http://marc.info/?l=linux-scsi&m=119754650614813&w=2
scsi: bidi support
http://marc.info/?l=linux-scsi&m=119754667915055&w=2
varlen
[PATCH 1/3] Let scsi_cmnd->cmnd use request->cmd buffer
http://marc.info/?l=linux-scsi&m=119798523823750&w=2
[PATCH 2/2] block layer varlen-cdb
http://marc.info/?l=linux-scsi&m=119798548624218&w=2
[PATCH 3/3] scsi: varlen extended and vendor-specific cdbs
http://marc.info/?l=linux-scsi&m=119798563924476&w=2
Then a few more, two modified from earlier Boaz patches, and three
new ones by me, mainly to make bsg work. They follow.
1. iscsi: extended cdb support
Adapted from Boaz
http://marc.info/?l=linux-scsi&m=119394074127857&w=2
2. iscsi: bidi support
Adapted from two old Boaz patches that can be found in this git:
http://www.bhalevy.com/git/gitweb.cgi?p=open-osd/.git;a=commitdiff;h=b5a97649eadb9434acbc4170a8aebd962af6d960

3. bsg: accept varlen commands
4. bsg: bidi fix
5. iscsi tcp: bidi capable
Suggestions: Boaz is probably the best qualified to shepherd his
outstanding five patches plus the two others I mention above (#1,
#2). The first bsg patch (#3) won't apply without the varlen
patches. The last two (#4, #5) are harmless and can go in now, but
won't matter until the bidi patches are in. Comments on these
welcome.
Hope this is helpful. I'm definitely looking forward to seeing
all this merged into mainline eventually.
