ODonnell, Michael [Wed, 11 Jan 2006 19:26:22 +0000 (11:26 -0800)]
[PATCH] corruption during e100 MDI register access

We have identified two related bugs in the e100 driver.

Both bugs are related to manipulation of the MDI control register.

The first problem is that the Ready bit is being ignored when writing to
the Control register; we noticed this because the Linux bonding driver
would occasionally come to the spurious conclusion that the link was down
when querying Link State.  It turned out that by failing to wait for a
previous command to complete it was selecting what was essentially a random
register in the MDI register set.  When we added code that waits for the
Ready bit (as shown in the patch file below) all such problems ceased.

The second problem is that, although access to the MDI registers involves
multiple steps which must not be intermixed, nothing was defending against
two or more threads attempting simultaneous access.  The most obvious
situation where such interference could occur involves the watchdog versus
ioctl paths, but there are probably others, so we recommend the locking
shown in our patch file.

[ARM] Allow r2 to be passed through the decompressor to the kernel

This is part of a patch from Marc Singer to allow r2 to be
passed to the kernel.  Marc's original comments follow:

This revised R2 (atags pointer) patch incorporates comments from Nico
Pitre and Ben Dooks. It modifies the head.S files such that the R2
value set by the bootloader is conveyed to the kernel startup code.
The kernel head.S heuristically validates the pointer. It will set R2
to zero if it believes the pointer is invalid. Presently, it requires
that the ATAGS list reside in the first 16KiB of physical RAM.
Relaxing this contraint may be both desirable as well as tricky.

[PATCH] m68k: oktagon makefile fix

oktagon_esp is described as modular.  However, drivers/scsi/Makefile doesn't
handle it right - it's multi-object module, with one of the parts being built
from .S.  Current makefile tries to declare each part a module of its own;
that not only wouldn't work (oktagon_io.o doesn't have the right parts for
that), it actually doesn't even build since kbuild doesn't believe in
single-object modules built from .S.  Turned into proper multi-object
module...

18 years ago[PATCH] missing helper - task_stack_page()
Al Viro [Thu, 12 Jan 2006 09:05:34 +0000 (01:05 -0800)]
[PATCH] missing helper - task_stack_page()

Patchset annotates arch/* uses of ->thread_info.  Ones that really are about
access of thread_info of given process are simply switched to
task_thread_info(task); ones that deal with access to objects on stack are
switched to new helper - task_stack_page().  A _lot_ of the latter are
actually open-coded instances of "find where pt_regs are"; those are
consolidated into task_pt_regs(task) (many architectures actually have such
helper already).

Note that these annotations are not mandatory - any code not converted to
these helpers still works.  However, they clean up a lot of places and have
actually caught a number of bugs, so converting out of tree ports would be a
good idea...

As an example of breakage caught by that stuff, see i386 pt_regs mess - we
used to have it open-coded in a bunch of places and when back in April Stas
had fixed a bug in copy_thread(), the rest had been left out of sync.  That
required two followup patches (the latest - just before 2.6.15) _and_ still
had left /proc/*/stat eip field broken.  Try ps -eo eip on i386 and watch the
junk...

This patch:

new helper - task_stack_page(task).  Returns pointer to the memory object
containing task stack; usually thread_info of task sits in the beginning
of that object.
