Bryan Wu [Tue, 18 Nov 2008 09:48:22 +0000]
Blackfin arch: fix bug - gpio_bank() macros messed up bank number caculating with positioning a gpio

The whole story:

Before BF51x merged, all the MAX_BLACKFIN_GPIOS are integral multiple of GPIO_BANKSIZE (= 16).
But BF51x provides MAX_BLACKFIN_GPIOS = 40 which includes 3 banks and the 3rd bank has only 8
GPIO pins.

Therefore, gpio_bank() macros is correct when you try to find a GPIO in which bank (GPIO_35 is
in bank 2). But on BF51x gpio_bank(MAX_BLACKFIN_GPIOS) only gives out 2 banks instead of 3
banks for some static array initialization.

This patch add a new macros gpio_bank_n() and GPIO_BANK_NUM to do bank number caculating and
remain the gpio_bank() macros for positioning a gpio in which bank.

11 years agobyteorder: only use linux/swab.h
Harvey Harrison [Tue, 6 Jan 2009 22:56:21 +0000]
byteorder: only use linux/swab.h

The first step to make swab.h a regular header that will
include an asm/swab.h with arch overrides.

Avoid the gratuitous differences introduced in the new
linux/swab.h by naming the ___constant_swabXX bits and
__fswabXX bits exactly as found in the old implementation
in byteorder/swab[b].h

Use this new swab.h in byteorder/[big|little]_endian.h and
remove the two old swab headers.

Although the inclusion of asm/byteorder.h looks strange in
linux/swab.h, this will allow each arch to move the actual
arch overrides for the swab bits in an asm file and then
the includes can be cleaned up without requiring a flag day
for all arches at once.

Keep providing __fswabXX in case some userspace was using them
directly, but the revised __swabXX should be used instead in
any new code and will always do constant folding not dependent
on the optimization level, which means the __constant versions
can be phased out in-kernel.

Arches that use the old-style arch macros will lose their
optimized versions until they move to the new style, but at
least they will still compile.  Many arches have already moved
and the patches to move the remaining arches are trivial.

parport: ieee1284: use del_timer_sync() in parport_wait_event()

Use del_timer_sync() instead of del_timer() to make sure the timer won't
be running when we return from parport_wait_event(), because this would
crash due to destruction of timer_list.

This is untested and just based on a code review.  Just think about the
following sequence of events:

- add_timer()

- down_interruptible() is interrupted by a signal.

- we enter the timer callback handler on another CPU.

- del_timer(), but the timer callback is still running.

- eturn from parport_wait_even, which destroys the automatic variable
  "timer" while the callback is running on another CPU.

Since all sanity checks rely on the validity of s_start which gets only
checked to be smaller than s_end, we should also check if s_end is sane.
Now we also try to retrieve the last block of the filesystem, which is

bfs_fill_super() already touches all inodes, so we can easily add some
cheap sanity checks and check if the inode start and end blocks are
smaller than the maximum number of blocks, the inode start block lies
behind the end block or the file end offset is behind the end of the
filesystem.  Also check if the start of data offset in the super block
fits the filesystem.

The added sanity checks catch softlockup issues early when we try to
sb_bread() lots of blocks in a loop in bfs_readdir() and bfs_find_entry().
 In addition an oom issue in bfs_fill_super() is prevented by this when
s_start is corrupted, which influences imap_len and we try to allocate a
huge info->si_imap.

11 years agodma-coherent: catch oversized requests to dma_alloc_from_coherent()

dma-coherent: catch oversized requests to dma_alloc_from_coherent()

Prevent passing an order to bitmap_find_free_region() that is larger than
the actual bitmap can represent.

These requests can come from device drivers that have no idea how big the
dma region is and need to rely on dma_alloc_from_coherent() to sort it out
for them.

11 years agodma_alloc_from_coherent(): fix fallback to generic memory
Andrew Morton [Tue, 6 Jan 2009 22:43:08 +0000]
dma_alloc_from_coherent(): fix fallback to generic memory

If bitmap_find_free_region() fails and DMA_MEMORY_EXCLUSIVE is not set,
the function will fail to write anything to *ret and will return 1.             This will cause dma_alloc_coherent() to return an uninitialised value,
crashing the kernel, perhaps via DMA to a random address.

Fix that by changing it to return zero in this case, so the caller will
proceed to allocate the memory from the generic memory allocator.

random: don't try to look at entropy_count outside the lock

As a non-atomic value, it's only safe to look at entropy_count when the
pool lock is held, so we move the BUG_ON inside the lock for correctness.

Also remove the spurious comment.  It's ok for entropy_count to
temporarily exceed POOLBITS so long as it's left in a consistent state
when the lock is released.

This is a more correct, simple, and idiomatic fix for the bug in

SEND_SIG_NOINFO: set si_pid to tgid instead of pid

POSIX requires the si_pid to be the process id of the sender, so ->si_pid
should really be set to 'tgid'.  This change does have following changes
in behavior:

- When sending pdeath_signal on re-parent to a sub-thread, ->si_pid
  cannot be used to identify the thread that did the re-parent since
  it will now show the tgid instead of thread id.

- A multi-threaded application that expects to find the specific
  thread that encountered a SIGPIPE using the ->si_pid will now
  break.
