SCSI advansys: Fix bug in AdvLoadMicrocode

2008-03-24T18:48:30+00:00

commit: 951b62c11e86acf8c55d9828aa8c921575023c29

buf[i] can be up to 0xfd, so doubling it and assigning the result to an
unsigned char truncates the value.  Just use an unsigned int instead;
it's only a temporary.

SCSI: gdth: fix to internal commands execution

2008-03-24T18:47:41+00:00

commit: ee54cc6af95a7fa09da298493b853a9e64fa8abd

The recent patch named:
  [SCSI] gdth: !use_sg cleanup and use of scsi accessors

has done a bad job in handling internal commands issued by gdth_execute().

Internal commands are issued with device gdth_cmd_str ready made directly
to the card, without any mapping or translations of scsi commands. So here
I added a gdth_cmd_str pointer to the gdth_cmndinfo private structure which
is then copied directly to host.

following this patch is a cleanup that removes the home cooked accessors
and reverts them to regular scsi_cmnd accessors. Since they are not used
anymore. After review maybe the 2 patches should be squashed together.

FIXME: There is still a problem with gdth_get_info(). as reported there
   is a WARN_ON trigerd in dma_free_coherent() when doing:
   $ cat /proc/sys/gdth/0

SCSI: gdth: bugfix for the at-exit problems

2008-03-24T18:47:41+00:00

commit: b31ddd31c266c2ad1b708cad0d3d8e0aa7fa2737

gdth_exit would first remove all cards then stop the timer
and would not sync with the timer function. This caused a crash
in gdth_timer() when module was unloaded.
So del_timer_sync the timer before we delete the cards.

also the reboot notifier function would crash. So clean
that up and fix the crashes.

Fix default compose table initialization

2008-03-24T18:47:40+00:00

commit: 5ce2087ed0eb424e0889bdc9102727f65d2ecdde

Oddly enough, unsigned int c = '\300'; puts a "negative" value in c, not
0300...  This fixes the default unicode compose table by using integers
instead of character constants.

SCSI: fix BUG when sum(scatterlist) > bufflen

2008-03-24T18:47:38+00:00

commit: 4d2de3a50ce19af2008a90636436a1bf5b3b697b

When sending a SCSI command to a tape drive via the SCSI Generic (sg)
driver, if the command has a data transfer length more than
scatter_elem_sz (32 KB default) and not a multiple of 512, then I either
hit BUG_ON(!valid_dma_direction(direction)) in dma_unmap_sg() or else
the command never completes (depending on the LLDD).

When constructing scatterlists, the sg driver rounds up the scatterlist
element sizes to be a multiple of 512.  This can result in
sum(scatterlist lengths) > bufflen.  In this case, scsi_req_map_sg()
incorrectly sets bio->bi_size to sum(scatterlist lengths) rather than to
bufflen.  When the command completes, req_bio_endio() detects that
bio->bi_size != 0, and so it doesn't call bio_endio().  This causes the
command to be resubmitted, resulting in BUG_ON or the command never
completing.

This patch makes scsi_req_map_sg() set bio->bi_size to bufflen rather
than to sum(scatterlist lengths), which fixes the problem.

USB: ehci: handle large bulk URBs correctly (again)

2008-03-24T18:47:36+00:00

commit: b5f7a0ec11694e60c99d682549dfaf8a03d7ad97

USB: ehci: Fixes completion for multi-qtd URB the short read case

When use of urb->status in the EHCI driver was reworked last August
(commit 14c04c0f88f228fee1f412be91d6edcb935c78aa), a bug was inserted
in the handling of early completion for bulk transactions that need
more than one qTD (e.g. more than 20KB in one URB).

This patch resolves that problem by ensuring that the early completion
status is preserved until the URB is handed back to its submitter,
instead of resetting it after each qTD.

VT notifier fix for VT switch

2008-03-24T18:47:34+00:00

commit: 8182ec49a73729334f5a6c65a607ba7009ebd6d6

VT notifier callbacks need to be aware of console switches.  This is already
partially done from console_callback(), but at that time fg_console, cursor
positions, etc.  are not yet updated and hence screen readers fetch the old
values.

This adds an update notify after all of the values are updated in
redraw_screen(vc, 1).
