[PATCH] USB: ub oops in block_uevent

2006-05-09T06:43:55+00:00

In kernel 2.6.16, if a mounted storage device is removed, an oops happens
because ub supplies an interface device (and kobject) to the block layer,
but neglects to pin it. And apparently, the block layer expects its users
to pin device structures.

The code in ub was broken this way for years. But the bug was exposed only
by 2.6.16 when it started to call block_uevent on close, which traverses
device structures (kobjects actually).

[PATCH] powerpc: Use check_legacy_ioport() on ppc32 too.

2006-04-28T11:04:55+00:00

Some people report that we die on some Macs when we are expecting to
catch machine checks after poking at some random I/O address. I'd seen
it happen on my dual G4 with serial ports until we fixed those to use
OF, but now other users are reporting it with i8042.

This expands the use of check_legacy_ioport() to avoid that situation
even on 32-bit kernels.

[PATCH] cciss: bug fix for crash when running hpacucli

2006-04-17T21:24:57+00:00

Fix a crash when running hpacucli with multiple logical volumes on a cciss
controller.  We were not properly initializing the disk->queue and causing
a fault.

Thanks to Hasso Tepper for reporting the problem.  Thanks to Steve Cameron
for root causing the problem.  Most of the patch just moves things around.
The fix is a one-liner.

[PATCH] Don't pass boot parameters to argv_init[]

2006-03-31T20:18:53+00:00

The boot cmdline is parsed in parse_early_param() and
parse_args(,unknown_bootoption).

And __setup() is used in obsolete_checksetup().

	start_kernel()
		-> parse_args()
			-> unknown_bootoption()
				-> obsolete_checksetup()

If __setup()'s callback (->setup_func()) returns 1 in
obsolete_checksetup(), obsolete_checksetup() thinks a parameter was
handled.

If ->setup_func() returns 0, obsolete_checksetup() tries other
->setup_func().  If all ->setup_func() that matched a parameter returns 0,
a parameter is seted to argv_init[].

Then, when runing /sbin/init or init=app, argv_init[] is passed to the app.
If the app doesn't ignore those arguments, it will warning and exit.

This patch fixes a wrong usage of it, however fixes obvious one only.

2006-03-28T17:16:02+00:00

If the user specified `major=0' (odd thing to do), pt.c will use dynamic
allocation.  We need to pick up that major for subsequent unregister_chrdev().
