pkt_sched: cls_u32: Fix locking in u32_change()

2009-01-25T00:41:42+00:00

[ Upstream commit: 6f57321422e0d359e83c978c2b03db77b967b7d5 ]

New nodes are inserted in u32_change() under rtnl_lock() with wmb(),
so without tcf_tree_lock() like in other classifiers (e.g. cls_fw).
This isn't enough without rmb() on the read side, but on the other
hand adding such barriers doesn't give any savings, so the lock is
added instead.

pkt_sched: sch_htb: Fix deadlock in hrtimers triggered by HTB

2009-01-25T00:41:42+00:00

[ Upstream commit: none

  This is a quick fix for -stable purposes.  Upstream fixes these
  problems via a large set of invasive hrtimer changes.  ]

Most probably there is a (still unproven) race in hrtimers (before
2.6.29 kernels), which causes a corruption of hrtimers rbtree. This
patch doesn't fix it, but should let HTB avoid triggering the bug.

The netem simulator is no longer limited by Linux timer resolution HZ.
Not since Patrick McHardy changed the QoS system to use hrtimer.

net: Do not fire linkwatch events until the device is registered.

2008-11-19T23:33:54+00:00

Several device drivers try to do things like netif_carrier_off()
before register_netdev() is invoked.  This is bogus, but too many
drivers do this to fix them all up in one go.

pkt_sched: sch_generic: Fix oops in sch_teql

2008-10-20T06:37:47+00:00

After these commands:
# modprobe sch_teql
# tc qdisc add dev eth0 root teql0
# tc qdisc del dev eth0 root
we get an oops in teql_destroy() when spin_lock is taken from a null
qdisc_sleeping pointer. It's because at the moment teql0 dev haven't
been activated yet, and a qdisc_root_sleeping() is pointing to noop
qdisc's netdev_queue with qdisc_sleeping uninitialized. This patch
fixes this both for noop and noqueue netdev_queues to avoid similar
problems in the future.

net: Remove CONFIG_KMOD from net/ (towards removing CONFIG_KMOD entirely)

2008-10-16T22:24:51+00:00

Some code here depends on CONFIG_KMOD to not try to load
protocol modules or similar, replace by CONFIG_MODULES
where more than just request_module depends on CONFIG_KMOD
and and also use try_then_request_module in ebtables.

pkt_sched: Update qdisc requeue stats in dev_requeue_skb()

2008-10-08T18:36:22+00:00

After the last change of requeuing there is no info about such
incidents in tc stats. This patch updates the counter, but we should
consider this should differ from previous stats because of additional
checks preventing to repeat this. On the other hand, previous stats
didn't include requeuing of gso_segmented skbs.
