[PATCH] IPMI: fix handling of OEM flags

2006-09-16T19:54:31+00:00

If one of the OEM flags becomes set in the flags from the hardware, the
driver could hang if no OEM handler was set.  Fix the code to handle this.
This was tested by setting the flags by hand after they were fetched.

[PATCH] IPMI: Fix oops on ipmi_msghandler removal for non ipmi systems

2006-09-16T19:54:30+00:00

When the ipmi_si module is loaded on a system without any ipmi device, it
fails with nodev.  It would be fine if all resources were freed.  A call to
device_unregister() is missing, resulting to a oops when you remove the
ipmi_msghandler.

[PATCH] IPMI: fix occasional oops on module unload

2006-09-01T18:39:09+00:00

Olaf Kirch of SuSE tracked down a problem where module unloads of the IPMI
driver would occasionally result in Oopses.  He tracked that down to a
variable that wasn't always initialized properly in some situations.  This
patch initializes that variable.  Olaf sent a patch that kzalloc-ed the
data, but this structure is large enough that I would perfer to not do
that.  Thanks Olaf!

[PATCH] synclink_gt: fix receive tty error handling

2006-09-01T18:39:08+00:00

Fix receive tty error handling in synclink_gt driver.  Adrian reported
compiler warning for incorrect bit test against char variable.  I
determined these and other device specific error bits were incorrectly
defined.

[PATCH] Fix tty layer DoS and comment relevant code

2006-08-27T18:01:34+00:00

Unlike the other tty comment patch this one has code changes.  Specifically
it limits the queue size for a tty to 64K characters (128Kbytes) worst case
even if the tty is ignoring tty->throttle.  This is because certain drivers
don't honour the throttle value correctly, although it is a useful
safeguard anyway.

[PATCH] vcsa attribute bits -> ioctl(VT_GETHIFONTMASK)

2006-08-27T18:01:29+00:00

When reading /dev/vcsa while a font with more than 256 characters is
loaded, one of the attribute bits records the 9th bit of the character.
But depending on the console driver (vgacon or fbcon for instance), that's
bit 3 or bit 0.  And there is no way for userland to know that, thus no way
for userland to safely grab the screen content.  So here is a (tested)
patch:

Add a VT_GETHIFONTMASK ioctl for knowing which bit is the 9th bit for VC
text (vc_hi_font_mask field of the vc_data structure).
