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.

Fold in upstream commit 10a7f3135ac4937a3dc8ed11614a2b70cbd44728 (Build
fix for drivers/s390/char/defkeymap.c) from Tony Breeds.

Commit 5ce2087ed0eb424e0889bdc9102727f65d2ecdde (Fix default compose
table initialization) left a trailing quote.

  CC      drivers/s390/char/defkeymap.o

drivers/s390/char/defkeymap.c:156: error: syntax error before ';' token
make[3]: *** [drivers/s390/char/defkeymap.o] Error 1

Fix that.

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).

drm: the drm really should call pci_set_master..

2008-02-08T19:46:29+00:00

(submitted upstream as 19a8f59ab8ceee751ea720085098355d53f727d6)

perhaps bonghits could turn on my bus-mastering because the drm
certainly never bothered doing it before.

vm audit: add VM_DONTEXPAND to mmap for drivers that need it (CVE-2008-0007)

2008-02-08T19:46:21+00:00

Drivers that register a ->fault handler, but do not range-check the
offset argument, must set VM_DONTEXPAND in the vm_flags in order to
prevent an expanding mremap from overflowing the resource.

I've audited the tree and attempted to fix these problems (usually by
adding VM_DONTEXPAND where it is not obvious).

TPM: fix suspend and resume failure

2008-01-14T16:52:22+00:00

The savestate command structure was being overwritten by the result of
running the TPM_SaveState command after one run, so make it a local
variable to the function instead of a global variable that gets
overwritten.

pl2303: Fix mode switching regression

2008-01-09T00:16:34+00:00

Cleaning out all the incorrect 'no change made' checks for termios
settings showed up a problem with the PL2303. The hardware here seems to
lose sync and bits if you tell it to make no changes. This shows up with
a real world application.

To fix this the driver check for meaningful hardware changes is restored
but doing the tests correctly and as a tty layer function so it doesn't
get duplicated wrongly everywhere if other drivers turn out to need it.

tty: fix logic change introduced by wait_event_interruptible_timeout()

2007-12-23T20:54:37+00:00

Commit 5a52bd4a2dcb570333ce6fe2e16cd311650dbdc8 introduced a subtle logic
change in tty_wait_until_sent().  The original version would only error out
of the 'do { ...  } while (timeout)' loop if signal_pending() evaluated to
true; a timeout or break due to an empty buffer would fall out of the loop
and into the tty->driver->wait_until_sent handling.  The current
implementation will error out on either a pending signal or an empty
buffer, falling through to the tty->driver->wait_until_sent handling only
on a timeout.

The ->wait_until_sent() will not be reached if the buffer empties before
timeout jiffies have elapsed.  This behavior differs from that prior to commit
5a52bd4a2dcb570333ce6fe2e16cd311650dbdc8.

I turned this up while using a little serial download utility to bootstrap an
ARM-based eval board.  The util worked fine on 2.6.22.x, but consistently
failed on 2.6.23.x.  Once I'd determined that, I narrowed things down with git
bisect, and found the above difference in logic in tty_wait_until_sent() by
inspection.

This change reverts the logic flow in tty_wait_until_sent() to match that
prior to the aforementioned commit.
