14 years ago[PATCH] tmpfs: time granularity fix for [acm]time going backwards
Robin H. Johnson [Mon, 12 Jun 2006 20:50:25 +0000]
[PATCH] tmpfs: time granularity fix for [acm]time going backwards

I noticed a strange behavior in a tmpfs file system the other day, while
building packages - occasionally, and seemingly at random, make decided to
rebuild a target. However, only on tmpfs.

A file would be created, and if checked, it had a sub-second timestamp.
However, after an utimes related call where sub-seconds should be set, they
were zeroed instead. In the case that a file was created, and utimes(...,NULL)
was used on it in the same second, the timestamp on the file moved backwards.

After some digging, I found that this was being caused by tmpfs not having a
time granularity set, thus inheriting the default 1 second granularity.

Hugh adds: yes, we missed tmpfs when the s_time_gran mods went into 2.6.11.
Unfortunately, the granularity of CURRENT_TIME, often used in filesystems,
does not match the default granularity set by alloc_super.  A few more such
discrepancies have been found, but this is the most important to fix now.

Aki M Nyrhinen [Mon, 12 Jun 2006 04:18:56 +0000]
[TCP]: continued: reno sacked_out count fix

From: Aki M Nyrhinen <anyrhine@cs.helsinki.fi>

IMHO the current fix to the problem (in_flight underflow in reno)
is incorrect.  it treats the symptons but ignores the problem. the
problem is timing out packets other than the head packet when we
don't have sack. i try to explain (sorry if explaining the obvious).

with sack, scanning the retransmit queue for timed out packets is
fine because we know which packets in our retransmit queue have been
acked by the receiver.

without sack, we know only how many packets in our retransmit queue the
receiver has acknowledged, but no idea which packets.

think of a "typical" slow-start overshoot case, where for example
every third packet in a window get lost because a router buffer gets
full.

with sack, we check for timeouts on those every third packet (as the
rest have been sacked). the packet counting works out and if there
is no reordering, we'll retransmit exactly the packets that were
lost.

without sack, however, we check for timeout on every packet and end up
retransmitting consecutive packets in the retransmit queue. in our
slow-start example, 2/3 of those retransmissions are unnecessary. these
unnecessary retransmissions eat the congestion window and evetually
prevent fast recovery from continuing, if enough packets were lost.

Paul Mackerras [Mon, 12 Jun 2006 02:16:26 +0000]
[PATCH] Fix for the PPTP hangs that have been reported

People have been reporting that PPP connections over ptys, such as
used with PPTP, will hang randomly when transferring large amounts of
data, for instance in http://bugzilla.kernel.org/show_bug.cgi?id=6530.
I have managed to reproduce the problem, and the patch below fixes the
actual cause.

The problem is not in fact in ppp_async.c but in n_tty.c.  What
happens is that when pptp reads from the pty, we call read_chan() in
drivers/char/n_tty.c on the master side of the pty.  That copies all
the characters out of its buffer to userspace and then calls
check_unthrottle(), which calls the pty unthrottle routine, which
calls tty_wakeup on the slave side, which calls ppp_asynctty_wakeup,
which calls tasklet_schedule.  So far so good.  Since we are in
process context, the tasklet runs immediately and calls
ppp_async_process(), which calls ppp_async_push, which calls the
tty->driver->write function to send some more output.

However, tty->driver->write() returns zero, because the master
tty->receive_room is still zero.  We haven't returned from
check_unthrottle() yet, and read_chan() only updates tty->receive_room
_after_ calling check_unthrottle.  That means that the driver->write
call in ppp_async_process() returns 0.  That would be fine if we were
going to get a subsequent wakeup call, but we aren't (we just had it,
and the buffer is now empty).

The solution is for n_tty.c to update tty->receive_room _before_
calling the driver unthrottle routine.  The patch below does this.
With this patch I was able to transfer a 900MB file over a PPTP
connection (taking about 25 minutes), whereas without the patch the
connection would always stall in under a minute.

[PATCH] PCI: reverse pci config space restore order

According to Intel ICH spec, there are several rules that Base Address
should be programmed before IOSE  (PCICMD register ) enabled.

For example ICH7:

12.1.3  SATA : the base address register for the bus master register
               should be programmed before this bit is set.

11.1.3:  PCICMD (USB): The base address register for USB should be
                       programmed before this bit is set.
....

To make sure kernel code follow this rule , and prevent unnecessary
confusion. I proposal this patch.

[PATCH] Further alterations for memory barrier document

From: David Howells <dhowells@redhat.com>

Apply some alterations to the memory barrier document that I worked out
with Paul McKenney of IBM, plus some of the alterations suggested by Alan
Stern.

The following changes were made:

 (*) One of the examples given for what can happen with overlapping memory
     barriers was wrong.

 (*) The description of general memory barriers said that a general barrier is
     a combination of a read barrier and a write barrier.  This isn't entirely
     true: it implies both, but is more than a combination of both.

 (*) The first example in the "SMP Barrier Pairing" section was wrong: the
     loads around the read barrier need to touch the memory locations in the
     opposite order to the stores around the write barrier.

 (*) Added a note to make explicit that the loads should be in reverse order to
     the stores.

 (*) Adjusted the diagrams in the "Examples Of Memory Barrier Sequences"
     section to make them clearer.  Added a couple of diagrams to make it more
     clear as to how it could go wrong without the barrier.

 (*) Added a section on memory speculation.

 (*) Dropped any references to memory allocation routines doing memory
     barriers.  They may do sometimes, but it can't be relied on.  This may be
     worthy of further documentation later.

 (*) Made the fact that a LOCK followed by an UNLOCK should not be considered a
     full memory barrier more explicit and gave an example.

   timeouts.

2) Always try to sync with the firmware, if there is no
   firmware running do not treat it as an error and instead
   just report it the first time we notice this condition.

3) If there is no valid SRAM signature, assume the device
   is onboard by setting TG3_FLAG_EEPROM_WRITE_PROT.

[PATCH] elevator switching race

There's a race between shutting down one io scheduler and firing up the
next, in which a new io could enter and cause the io scheduler to be
invoked with bad or NULL data.

To fix this, we need to maintain the queue lock for a bit longer.
Unfortunately we cannot do that, since the elevator init requires to be
run without the lock held.  This isn't easily fixable, without also
changing the mempool API.  So split the initialization into two parts,
and alloc-init operation and an attach operation.  Then we can
preallocate the io scheduler and related structures, and run the attach
inside the lock after we detach the old one.

This patch has survived 30 minutes of 1 second io scheduler switching
with a very busy io load.

14 years ago[ARM] 3546/1: PATCH: subtle lost interrupts bug on i.MX
Matt Reimer [Thu, 8 Jun 2006 21:46:48 +0000]
[ARM] 3546/1: PATCH: subtle lost interrupts bug on i.MX

Patch from Matt Reimer

There is a subtle bug in the GPIO interrupt status register
handling in arch/arm/mach-imx/irq.c:imx_gpio_ack_irq(). The
documentation states that a 1 should be written to the relevant bit to
acknowledge a GPIO interrupt, but that is not what the code does.

The problem is that the |= writes back 1s for all the *other*
interrupts represented in the register, so interrupts could get lost.
For example, if interrupts are pending for GPIO B10 and B12, ISR_B
would have the value 0x00001400. Then when the interrupt code handles
GPIO B10, it eventually calls imx_gpio_ack_irq(IRQ_GPIOB(10)), which
effectively does this:

ISR_B |= 1 << 10;

with the result that (0x00001400 | 0x00000400) is written, clearing
the interrupt status bits for *both* GPIO B10 and B12.

The fix is to write 1s only for the interrupts we want to clear.

The same problem seems to be occurring in the DMA code; this patch
does not address those issues.

[ARM] Fix Neponset IRQ handling

While testing the genirq code on ARM, a condition was found whereby
the Neponset IRQ handler was being re-entered, causing the system
to deadlock.

Under the ARM IRQ code, this would not have been a visible problem
because the "simple" IRQ handling had no re-entrancy protection.

Resolve this by acknowledging the parent interrupt after we mask it
when we are going to handle one of our "special" level-based sources
(from ethernet or USAR chip.)

14 years ago[TCP]: Avoid skb_pull if possible when trimming head
Herbert Xu ~{PmVHI~} [Mon, 5 Jun 2006 22:03:37 +0000]
[TCP]: Avoid skb_pull if possible when trimming head

Trimming the head of an skb by calling skb_pull can cause the packet
to become unaligned if the length pulled is odd.  Since the length is
entirely arbitrary for a FIN packet carrying data, this is actually
quite common.

Unaligned data is not the end of the world, but we should avoid it if
it's easily done.  In this case it is trivial.  Since we're discarding
all of the head data it doesn't matter whether we move skb->data forward
or back.

However, it is still possible to have unaligned skb->data in general.
So network drivers should be prepared to handle it instead of crashing.

This patch also adds an unlikely marking on len < headlen since partial
ACKs on head data are extremely rare in the wild.  As the return value
of __pskb_trim_head is no longer ever NULL that has been removed.

From: Ivan Kokshaysky <ink@jurassic.park.msu.ru>

After removal of fixup_cpu_present_map() function Alpha ended up with an empty
cpu_present_map, so secondary CPUs on SMP systems are not being started.

Worse, on some platforms we route interrupts to secondary CPUs using
cpu_possible_map which is still populated properly.  As a result, these
interrupts go nowhere so the machines like DP264 aren't able to boot even with
a primary CPU.

Fixed basically by s/cpu_present_mask/cpu_present_map/.

[PATCH] Sparsemem build fix

From: Ralf Baechle <ralf@linux-mips.org>

<linux/mmzone.h> uses PAGE_SIZE, PAGE_SHIFT from <asm/page.h> without
including that header itself.  For some sparsemem configurations this may
result in build errors like:

14 years ago[PATCH] s390: cio non-unique path group ids
Peter Oberparleiter [Sun, 4 Jun 2006 09:51:28 +0000]
[PATCH] s390: cio non-unique path group ids

From: Peter Oberparleiter <peter.oberparleiter@de.ibm.com>

The path grouping can fail due to non-unique pathgroup-IDs.  The source for
the CPU-ID part of the ID was incorrectly specified on 64 bit systems.
Additionally, the length of the ID was too large due to incorrect data packing
declaration.  Fix CPU-ID lowcore address and add missing packing declaration.
