10 years agoxfrm: SAD entries do not expire correctly after suspend-resume
Yury Polyanskiy [Mon, 9 Nov 2009 04:58:41 +0000]
xfrm: SAD entries do not expire correctly after suspend-resume

  This fixes the following bug in the current implementation of
net/xfrm: SAD entries timeouts do not count the time spent by the machine
in the suspended state. This leads to the connectivity problems because
after resuming local machine thinks that the SAD entry is still valid, while
it has already been expired on the remote server.

  The cause of this is very simple: the timeouts in the net/xfrm are bound to
the old mod_timer() timers. This patch reassigns them to the
CLOCK_REALTIME hrtimer.

  I have been using this version of the patch for a few months on my
machines without any problems. Also run a few stress tests w/o any
issues.

  This version of the patch uses tasklet_hrtimer by Peter Zijlstra
(commit 9ba5f0).

  This patch is against 2.6.31.4. Please CC me.

Extends udp_table to contain a secondary hash table.

socket anchor for this second hash is free, because UDP

udp_lib_unhash() deletes socket from second hash chain
(additional cost of one atomic op)

net: Support specifying the network namespace upon device creation.

There is no good reason to not support userspace specifying the
network namespace during device creation, and it makes it easier
to create a network device and pass it to a child network namespace
with a well known name.

We have to be careful to ensure that the target network namespace
for the new device exists through the life of the call.  To keep
that logic clear I have factored out the network namespace grabbing
logic into rtnl_link_get_net.

In addtion we need to continue to pass the source network namespace
to the rtnl_link_ops.newlink method so that we can find the base
device source network namespace.

These warnings are not easy to fix without ugly __force casts. So,
instead of introducing the casts, rework the code to substitute an
offset from an already mapped area. This makes the code a lot simpler

Plus, from now on we don't actually map reserved registers on

Slip and a few other drivers use the same ioctl numbers on

to handle the conversion itself so we can contain the

This also fixes a bug in the handling of invalid ioctl
numbers on an unbound tun device. The driver treats this
as a TUNSETIFF in native mode, but there is no way for
the generic compat_ioctl() function to emulate this
behaviour. Possibly the driver was only doing this
accidentally anyway, but if any code relies on this
misfeature, it now also works in compat mode.

Herbert Xu [Fri, 6 Nov 2009 10:37:41 +0000]
ipip: Fix handling of DF packets when pmtudisc is OFF

RFC 2003 requires the outer header to have DF set if DF is set
on the inner header, even when PMTU discovery is off for the
tunnel.  Our implementation does exactly that.

For this to work properly the IPIP gateway also needs to engate
in PMTU when the inner DF bit is set.  As otherwise the original
host would not be able to carry out its PMTU successfully since
part of the path is only visible to the gateway.

Unfortunately when the tunnel PMTU discovery setting is off, we
do not collect the necessary soft state, resulting in blackholes
when the original host tries to perform PMTU discovery.

This problem is not reproducible on the IPIP gateway itself as
the inner packet usually has skb->local_df set.  This is not
correctly cleared (an unrelated bug) when the packet passes
through the tunnel, which allows fragmentation to occur.  For
hosts behind the IPIP gateway it is readily visible with a simple
ping.

This patch fixes the problem by performing PMTU discovery for
all packets with the inner DF bit set, regardless of the PMTU
discovery setting on the tunnel itself.

10 years agomac80211: async station powersave handling
Johannes Berg [Fri, 6 Nov 2009 10:35:50 +0000]
mac80211: async station powersave handling

Some devices require that all frames to a station
are flushed when that station goes into powersave
mode before being able to send frames to that
station again when it wakes up or polls -- all in
order to avoid reordering and too many or too few
frames being sent to the station when it polls.

Normally, this is the case unless the station
goes to sleep and wakes up very quickly again.
But in that case, frames for it may be pending
on the hardware queues, and thus races could
happen in the case of multiple hardware queues
used for QoS/WMM. Normally this isn't a problem,
but with the iwlwifi mechanism we need to make
sure the race doesn't happen.

This makes mac80211 able to cope with the race
with driver help by a new WLAN_STA_PS_DRIVER
per-station flag that can be controlled by the
driver and tells mac80211 whether it can transmit
frames or not. This flag must be set according to
very specific rules outlined in the documentation
for the function that controls it.

When we buffer new frames for the station, we
normally set the TIM bit right away, but while
the driver has blocked transmission to that sta
we need to avoid that as well since we cannot
respond to the station if it wakes up due to the
TIM bit. Once the driver unblocks, we can set
the TIM bit.

Similarly, when the station just wakes up, we
need to wait until all other frames are flushed
before we can transmit frames to that station,
so the same applies here, we need to wait for
the driver to give the OK.
