lowmem: get rid of the percentages

The purpose of this patch is to get rid of the lame percentage calculations in
lowmem.c. Currently, the limits (measured in pages) are calculated from
percentages every time somebody from userspace requests some memory. With this
patch, the limits are in pages and furthermore, they are specified as minimum
amount of "free pages", instead of as maximum amount of "used pages". "Free"
means free pages or such pages that can easily be freed by the VM system.

This patch changes the names of the lowmem sysctl limits in /proc/sys/vm:
lowmem_deny_watermark        => lowmem_deny_watermark_pages
lowmem_notify_low      => lowmem_notify_low_pages
lowmem_notify_high       => lowmem_notify_high_pages

The following read only value disappears:
lowmem_used_pages

The following read only value is introduced:
lowmem_free_pages

The old value can be calculated from userspace with the following pseudocode:

if lowmem_free_pages < lowmem_allowed_pages
   lowmem_used_pages = lowmem_allowed_pages - lowmem_free_pages
else
   lowmem_used_pages = 0;

Note that the value of lowmem_free_pages is only accurate when the system is
rather low on memory (otherwise it's a bit too pessimistic), this was true also
for the lowmem_used_pages metric.

twl4030: improve rtc device setup

Make the twl4030 RTC initialization follow the driver model better.
The platform device is created (if needed) as part of twl4030 setup
instead of as a board-specific thing, and fits properly into the
driver model tree.

The only minor glitch here is on boards using platform_data to pass
MSECURE initialization hooks to the RTC driver.  The right solution
probably just removes that platform_data, and might even make Linux
follow the principle of "least privilege" (at the hardware level!)
instead of always holding this signal high.

Pending better handling of MSECURE, this patch just does what the
RTC init does, but earlier:  MSECURE is always high, so the RTC time
and calendar registers can be updated (and presumably a bunch of
non-RTC privileged operations will be allowed too).

Yet to be done:  set up the IRQ resource; make the rtc driver use
that IRQ resource; and properly issue wakeup alarms.

Marcel Holtmann [Tue, 9 Sep 2008 05:19:20 +0000 (07:19 +0200)]
[Bluetooth] Reject L2CAP connections on an insecure ACL link

The Security Mode 4 of the Bluetooth 2.1 specification has strict
authentication and encryption requirements. It is the initiators job
to create a secure ACL link. However in case of malicious devices, the
acceptor has to make sure that the ACL is encrypted before allowing
any kind of L2CAP connection. The only exception here is the PSM 1 for
the service discovery protocol, because that is allowed to run on an
insecure ACL link.

Previously it was enough to reject a L2CAP connection during the
connection setup phase, but with Bluetooth 2.1 it is forbidden to
do any L2CAP protocol exchange on an insecure link (except SDP).

The new hci_conn_check_link_mode() function can be used to check the
integrity of an ACL link. This functions also takes care of the cases
where Security Mode 4 is disabled or one of the devices is based on
an older specification.

Marcel Holtmann [Tue, 9 Sep 2008 05:19:20 +0000 (07:19 +0200)]
[Bluetooth] Enforce correct authentication requirements

With the introduction of Security Mode 4 and Simple Pairing from the
Bluetooth 2.1 specification it became mandatory that the initiator
requires authentication and encryption before any L2CAP channel can
be established. The only exception here is PSM 1 for the service
discovery protocol (SDP). It is meant to be used without any encryption
since it contains only public information. This is how Bluetooth 2.0
and before handle connections on PSM 1.

For Bluetooth 2.1 devices the pairing procedure differentiates between
no bonding, general bonding and dedicated bonding. The L2CAP layer
wrongly uses always general bonding when creating new connections, but it
should not do this for SDP connections. In this case the authentication
requirement should be no bonding and the just-works model should be used,
but in case of non-SDP connection it is required to use general bonding.

If the new connection requires man-in-the-middle (MITM) protection, it
also first wrongly creates an unauthenticated link key and then later on
requests an upgrade to an authenticated link key to provide full MITM
protection. With Simple Pairing the link key generation is an expensive
operation (compared to Bluetooth 2.0 and before) and doing this twice
during a connection setup causes a noticeable delay when establishing
a new connection. This should be avoided to not regress from the expected
Bluetooth 2.0 connection times. The authentication requirements are known
up-front and so enforce them.

To fulfill these requirements the hci_connect() function has been extended
with an authentication requirement parameter that will be stored inside
the connection information and can be retrieved by userspace at any
time. This allows the correct IO capabilities exchange and results in
the expected behavior.

The ACL config stage keeps holding a reference count on incoming

the Bluetooth specification doesn't define an ownership of the ACL
link and thus it can happen that the implementation on the initiator

16 years agoNFS: Restore missing hunk in NFS mount option parser
Chuck Lever [Mon, 8 Sep 2008 15:58:13 +0000 (11:58 -0400)]
NFS: Restore missing hunk in NFS mount option parser

Automounter maps can contain mount options valid for other NFS
implementations but not for Linux.  The Linux automounter uses the
mount command's "-s" command line option ("s" for "sloppy") so that
mount requests containing such options are not rejected.

Commit f45663ce5fb30f76a3414ab3ac69f4dd320e760a attempted to address a
known regression with text-based NFS mount option parsing.  Unrecognized
mount options would cause mount requests to fail, even if the "-s"
option was used on the mount command line.

Unfortunately, this commit was not complete as submitted.  It adds a
new mount option, "sloppy".  But it is missing a hunk, so it now allows
NFS mounts with unrecognized mount options, even if the "sloppy" option
is not present.  This could be a problem if a required critical mount
option such as "sync" is misspelled, for example, and is considered a
regression from 2.6.26.

This patch restores the missing hunk.  Now, the default behavior of
text-based NFS mount options is as before: any unrecognized mount option
will cause the mount to fail.

Please include this in 2.6.27-rc.

Thanks to Neil Brown for reporting this.

16 years agobridge: don't allow setting hello time to zero
Stephen Hemminger [Mon, 8 Sep 2008 20:44:40 +0000 (13:44 -0700)]
bridge: don't allow setting hello time to zero

Dushan Tcholich reports that on his system ksoftirqd can consume
between %6 to %10 of cpu time, and cause ~200 context switches per
second.

He then correlated this with a report by bdupree@techfinesse.com:

http://marc.info/?l=linux-kernel&m=119613299024398&w=2

and the culprit cause seems to be starting the bridge interface.
In particular, when starting the bridge interface, his scripts
are specifying a hello timer interval of "0".

The bridge hello time can't be safely set to values less than 1
second, otherwise it is possible to end up with a runaway timer.

This patch provides a function to purge all timewait sockets related
to a network namespace. The timewait sockets life cycle is not tied with
the network namespace, that means the timewait sockets stay alive while
the network namespace dies. The timewait sockets are for avoiding to
receive a duplicate packet from the network, if the network namespace is
freed, the network stack is removed, so no chance to receive any packets
from the outside world. Furthermore, having a pending destruction timer
on these sockets with a network namespace freed is not safe and will lead
to an oops if the timer callback which try to access data belonging to
the namespace like for example in:
inet_twdr_do_twkill_work
-> NET_INC_STATS_BH(twsk_net(tw), LINUX_MIB_TIMEWAITED);

Purging the timewait sockets at the network namespace destruction will:
 1) speed up memory freeing for the namespace
 2) fix kernel panic on asynchronous timewait destruction

16 years agox86: disable static NOPLs on 32 bits

x86: disable static NOPLs on 32 bits

On 32-bit, at least the generic nops are fairly reasonable, but the
default nops for 64-bit really look pretty sad, and the P6 nops really do
look better.

So I would suggest perhaps moving the static P6 nop selection into the
CONFIG_X86_64 thing.

The alternative is to just get rid of that static nop selection, and just
have two cases: 32-bit and 64-bit, and just pick obviously safe cases for
them.
