David Brownell [Sat, 30 Dec 2006 00:48:39 +0000 (16:48 -0800)]
[PATCH] SPI: define null tx_buf to mean "shift out zeroes"

Some issues were recently turned up with the current specification of what
it means for spi_transfer.tx_buf to be null, as part of transfers which are
(from the SPI protocol driver perspective) pure reads.

Specifically, that it seems better to change the TX behaviour there from
"undefined" to "will shift zeroes".  This lets protocol drivers (like the
ads7846 driver) depend on that behavior.  It's what most controller drivers
in the tree are already doing (with one exception and one case of driver
wanting-to-oops), it's what Microwire hardware will necessarily be doing,
and it removes an issue whereby certain security audits would need to
define such a value anyway as part of removing covert channels.

This patch changes the specification to require shifting zeroes, and
updates all currently merged SPI controller drivers to do so.

[PATCH] sched: fix cond_resched_softirq() offset

Remove the __resched_legal() check: it is conceptually broken.  The biggest
problem it had is that it can mask buggy cond_resched() calls.  A
cond_resched() call is only legal if we are not in an atomic context, with
two narrow exceptions:

 - if the system is booting
 - a reacquire_kernel_lock() down() done while PREEMPT_ACTIVE is set

But __resched_legal() hid this and just silently returned whenever
these primitives were called from invalid contexts. (Same goes for
cond_resched_locked() and cond_resched_softirq()).

Furthermore, the __legal_resched(0) call was buggy in that it caused
unnecessarily long softirq latencies via cond_resched_softirq().  (which is
only called from softirq-off sections, hence the code did nothing.)

The fix is to resurrect the efficiency of the might_sleep checks and to
only allow the narrow exceptions.

[PATCH] Fix lock inversion aio_kick_handler()

1) The task struct's alloc_lock (A) is acquired in process context with
   interrupts enabled.  An interrupt might arrive and call wake_up() which
   grabs the wait queue's q->lock (B).

2) When performing retry-based AIO the AIO core registers
   aio_wake_function() as the wake funtion for iocb->ki_wait.  It is called
   with the wait queue's q->lock (B) held and then tries to add the iocb to
   the run list after acquiring the ctx_lock (C).

3) aio_kick_handler() holds the ctx_lock (C) while acquiring the
   alloc_lock (A) via lock_task() and unuse_mm().  Lockdep emits a warning
   saying that we're trying to connect the irq-safe q->lock to the
   irq-unsafe alloc_lock via ctx_lock.

This fixes the inversion by calling unuse_mm() in the AIO kick handing path
after we've released the ctx_lock.  As Ben LaHaise pointed out __put_ioctx
could set ctx->mm to NULL, so we must only access ctx->mm while we have the
lock.

17 years agoVM: Fix nasty and subtle race in shared mmap'ed page writeback
Linus Torvalds [Fri, 29 Dec 2006 18:00:58 +0000 (10:00 -0800)]
VM: Fix nasty and subtle race in shared mmap'ed page writeback

The VM layer (on the face of it, fairly reasonably) expected that when
it does a ->writepage() call to the filesystem, it would write out the
full page at that point in time.  Especially since it had earlier marked
the whole page dirty with "set_page_dirty()".

But that isn't actually the case: ->writepage() does not actually write
a page, it writes the parts of the page that have been explicitly marked
dirty before, *and* that had not got written out for other reasons since
the last time we told it they were dirty.

That last caveat is the important one.

Which _most_ of the time ends up being the whole page (since we had
called "set_page_dirty()" on the page earlier), but if the filesystem
had done any dirty flushing of its own (for example, to honor some
internal write ordering guarantees), it might end up doing only a
partial page IO (or none at all) when ->writepage() is actually called.

That is the correct thing in general (since we actually often _want_
only the known-dirty parts of the page to be written out), but the
shared dirty page handling had implicitly forgotten about these details,
and had a number of cases where it was doing just the "->writepage()"
part, without telling the low-level filesystem that the whole page might
have been re-dirtied as part of being mapped writably into user space.

Since most of the time the FS did actually write out the full page, we
didn't notice this for a loong time, and this needed some really odd
patterns to trigger.  But it caused occasional corruption with rtorrent
and with the Debian "apt" database, because both use shared mmaps to
update the end result.

This fixes it. Finally. After way too much hair-pulling.

17 years agoe1000: Do not truncate TSO TCP header with 82544 workaround
Herbert Xu [Sat, 16 Dec 2006 01:04:33 +0000 (12:04 +1100)]
e1000: Do not truncate TSO TCP header with 82544 workaround

The e1000 driver has a workaround for 82544 on PCI-X where if the
terminating byte of a buffer is at addresses 0-3 mod 8, then 4 bytes
are shaved off it and defered to a new segment.  This is due to an
erratum that could otherwise cause TX hangs.

Unfortunately this breaks TSO because it may cause the TCP header to
be split over two segments which itself causes TX hangs.  The solution
is to pull 4 bytes of data up from the next segment rather than pushing
4 bytes off.  This ensures the TCP header remains in one piece and
works around the PCI-X hang.

This patch is based on one from Jesse Brandeburg.

This bug has been trigered by both CONFIG_DEBUG_SLAB as well as Xen.

Note that the only reason we don't see this normally is because the
TCP stack starts writing from the end, i.e., it writes the TCP header
first then slaps on the IP header, etc.  So the end of the TCP header
(skb->tail - 1 here) is always aligned correctly.

Had we made the start of the IP header (e.g., IPv6) 8-byte aligned
instead, this would happen for normal TCP traffic as well.

[PATCH] e1000: Make the copybreak value a module parameter

Allow the user to vary the size that copybreak works. Currently cb is enabled
for packets < 256 bytes, but various tests indicate that this should be
configurable for specific use cases. In addition, this parameter allows us
to force never/always during testing to get full and predictable coverage of
both code paths.

[PATCH] e1000: Fix PBA allocation calculations

Assign the PBA to be large enough to contain at least 2 jumbo frames on
all adapters. This dramatically increases performance on several adapters
and fixes TX performance degradation issues where the PBA was misallocated
in the old algorithm.
