12 years agoCPU online file permission
Ulrich Drepper [Tue, 31 Jul 2007 07:38:16 +0000]
CPU online file permission

Is there a reason why the "online" file in the subdirectories for the CPUs
in /sys/devices/system isn't world-readable?  I cannot imagine it to be
security relevant especially now that a getcpu() syscall can be used to
determine what CPUa thread runs on.

The file is useful to correctly implement the sysconf() function to return
the number of online CPUs.  In the presence of hotplug we currently cannot
provide this information.  The patch below should to it.

Andrew Morton [Tue, 31 Jul 2007 07:38:02 +0000]
revert "x86, serial: convert legacy COM ports to platform devices"

Revert 7e92b4fc345f5b6f57585fbe5ffdb0f24d7c9b26.  It broke Sébastien Dugué's
machine and Jeff said (persuasively)

  This seems like it will break decades-long-working stuff, in favor of
  breaking new ground in our favorite area, "trusting the BIOS."

  It's just not worth it for serial ports, IMO.  Serial ports are something
  that just shouldn't break at this late stage in the game.  My new Intel
  platform boxes don't even have serial ports, so I question the value of
  messing with serial port probing even more...  because...  just wait a year,
  and your box won't have a serial port either!  :)

  I certainly don't object to the use of platform devices (or isa_driver),
  but the probe change seems questionable.  That's sorta analagous to
  rewriting the floppy driver probe routine.  Sure you could do it...  but why
  risk all that damage and go through debugging all over again?

  It seems clear from this report that we cannot, should not, trust BIOS for
  something (a) so simple and (b) that has been working for over a decade.

Much discussion ensued and we've decided to have another go at all of this.

knfsd: eliminate unnecessary -ENOENT returns on export downcalls

A succesful downcall with a negative result (which indicates that the given
filesystem is not exported to the given user) should not return an error.

Currently mountd is depending on stdio to write these downcalls.  With some
versions of libc this appears to cause subsequent writes to attempt to write
all accumulated data (for which writes previously failed) along with any new
data.  This can prevent the kernel from seeing responses to later downcalls.
Symptoms will be that nfsd fails to respond to certain requests.

RFC 3530 says:

 If the server uses an attribute to store the exclusive create verifier, it
 will signify which attribute by setting the appropriate bit in the attribute
 mask that is returned in the results.

Linux uses the atime and mtime to store the verifier, but sends a zeroed out
bitmask back to the client.  This patch makes sure that we set the correct

12 years agoDo not trigger OOM-killer for high-order allocation failures
Mel Gorman [Tue, 31 Jul 2007 07:37:30 +0000]
Do not trigger OOM-killer for high-order allocation failures

out_of_memory() may be called when an allocation is failing and the direct
reclaim is not making any progress.  This does not take into account the
requested order of the allocation.  If the request if for an order larger
than PAGE_ALLOC_COSTLY_ORDER, it is reasonable to fail the allocation
because the kernel makes no guarantees about those allocations succeeding.

This false OOM situation can occur if a user is trying to grow the hugepage
pool in a script like;

#!/bin/bash
REQUIRED=$1
echo 1 > /proc/sys/vm/hugepages_treat_as_movable
echo $REQUIRED > /proc/sys/vm/nr_hugepages
ACTUAL=`cat /proc/sys/vm/nr_hugepages`
while [ $REQUIRED -ne $ACTUAL ]; do
echo Huge page pool at $ACTUAL growing to $REQUIRED
echo $REQUIRED > /proc/sys/vm/nr_hugepages
ACTUAL=`cat /proc/sys/vm/nr_hugepages`
sleep 1
done

This is a reasonable scenario when ZONE_MOVABLE is in use but triggers OOM
easily on 2.6.23-rc1. This patch will fail an allocation for an order above
PAGE_ALLOC_COSTLY_ORDER instead of killing processes and retrying.

overhead).  Because intstatus was not read, we could miss the error

12 years agonetxen: drop redudant spinlock
Dhananjay Phadke [Fri, 27 Jul 2007 17:42:11 +0000]
netxen: drop redudant spinlock

Some leftover code that makes use of adapter->lock in tx_timeout function,
which resets the interface under this lock. In close() when the workqueue
is flushed, prints the warning about sleeping with interrupts disabled
(when spinlock debug is enabled). The lock was required with private netxen
IOCTLs, which were removed a while ago.

12 years agonetxen: Fix interrupt handling for multiport adapters

netxen: Fix interrupt handling for multiport adapters

This patch fixes masking of interrupts on multiport adapters. Also disables
interrupts upon ifdown interface. The wrong mask could result in interrupt
flood after interface is down.
