2011-05-24igmp: call ip_mc_clear_src() only when we have no users of ip_mc_listVeaceslav Falico1-5/+5
In igmp_group_dropped() we call ip_mc_clear_src(), which resets the number of source filters per mulitcast. However, igmp_group_dropped() is also called on NETDEV_DOWN, NETDEV_PRE_TYPE_CHANGE and NETDEV_UNREGISTER, which means that the group might get added back on NETDEV_UP, NETDEV_REGISTER and NETDEV_POST_TYPE_CHANGE respectively, leaving us with broken source filters. To fix that, we must clear the source filters only when there are no users in the ip_mc_list, i.e. in ip_mc_dec_group() and on device destroy.

2011-05-24net: convert %p usage to %pKDan Rosenberg14-22/+22
The %pK format specifier is designed to hide exposed kernel pointers, specifically via /proc interfaces. Exposing these pointers provides an easy target for kernel write vulnerabilities, since they reveal the locations of writable structures containing easily triggerable function pointers. The behavior of %pK depends on the kptr_restrict sysctl. If kptr_restrict is set to 0, no deviation from the standard %p behavior occurs. If kptr_restrict is set to 1, the default, if the current user (intended to be a reader via seq_printf(), etc.) does not have CAP_SYSLOG (currently in the LSM tree), kernel pointers using %pK are printed as 0's. If kptr_restrict is set to 2, kernel pointers using %pK are printed as 0's regardless of privileges. Replacing with 0's was chosen over the default "(null)", which cannot be parsed by userland %p, which expects "(nil)". The supporting code for kptr_restrict and %pK are currently in the -mm tree. This patch converts users of %p in net/ to %pK. Cases of printing pointers to the syslog are not covered, since this would eliminate useful information for postmortem debugging and the reading of the syslog is already optionally protected by the dmesg_restrict sysctl.

2011-05-23sch_sfq: avoid giving spurious NET_XMIT_CN signalsEric Dumazet1-2/+6
While chasing a possible net_sched bug, I found that IP fragments have litle chance to pass a congestioned SFQ qdisc : - Say SFQ qdisc is full because one flow is non responsive. - ip_fragment() wants to send two fragments belonging to an idle flow. - sfq_enqueue() queues first packet, but see queue limit reached : - sfq_enqueue() drops one packet from 'big consumer', and returns NET_XMIT_CN. - ip_fragment() cancel remaining fragments. This patch restores fairness, making sure we return NET_XMIT_CN only if we dropped a packet from the same flow.

2011-05-22net: avoid synchronize_rcu() in dev_deactivate_manyEric Dumazet1-2/+15
dev_deactivate_many() issues one synchronize_rcu() call after qdiscs set to noop_qdisc. This call is here to make sure they are no outstanding qdisc-less dev_queue_xmit calls before returning to caller. But in dismantle phase, we dont have to wait, because we wont activate again the device, and we are going to wait one rcu grace period later in rollback_registered_many(). After this patch, device dismantle uses one synchronize_net() and one rcu_barrier() call only, so we have a ~30% speedup and a smaller RTNL latency.

So one synchronize_net() call was needed in netdev_set_master() to make sure another cpu could not use old master while/after we release it. We now use netdev_rx_handler infrastructure and added one synchronize_net() call in bond_release()/bond_release_all() Remove the obsolete synchronize_net() from netdev_set_master() and add one in bridge del_nbp() after its netdev_rx_handler_unregister() call.
