2010-11-24af_unix: limit unix_tot_inflightEric Dumazet1-0/+7
Vegard Nossum found a unix socket OOM was possible, posting an exploit program. My analysis is we can eat all LOWMEM memory before unix_gc() being called from unix_release_sock(). Moreover, the thread blocked in unix_gc() can consume huge amount of time to perform cleanup because of huge working set. One way to handle this is to have a sensible limit on unix_tot_inflight, tested from wait_for_unix_gc() and to force a call to unix_gc() if this limit is hit. This solves the OOM and also reduce overall latencies, and should not slowdown normal workloads.

2010-11-18net: zero kobject in rx_queue_releaseJohn Fastabend1-2/+8
netif_set_real_num_rx_queues() can decrement and increment the number of rx queues. For example ixgbe does this as features and offloads are toggled. Presumably this could also happen across down/up on most devices if the available resources changed (cpu offlined). The kobject needs to be zero'd in this case so that the state is not preserved across kobject_put()/kobject_init_and_add(). This resolves the following error report. ixgbe 0000:03:00.0: eth2: NIC Link is Up 10 Gbps, Flow Control: RX/TX kobject (ffff880324b83210): tried to init an initialized object, something is seriously wrong.

2010-11-12ipv6: addrconf: don't remove address state on ifdown if the address is being ↵Lorenzo Colitti1-16/+8
kept Currently, addrconf_ifdown does not delete statically configured IPv6 addresses when the interface is brought down. The intent is that when the interface comes back up the address will be usable again. However, this doesn't actually work, because the system stops listening on the corresponding solicited-node multicast address, so the address cannot respond to neighbor solicitations and thus receive traffic. Also, the code notifies the rest of the system that the address is being deleted (e.g, RTM_DELADDR), even though it is not. Fix it so that none of this state is updated if the address is being kept on the interface. Tested: Added a statically configured IPv6 address to an interface, started ping, brought link down, brought link up again. When link came up ping kept on going and "ip -6 maddr" showed that the host was still subscribed to there Signed-off-by: Lorenzo Colitti <lorenzo@google.com> Signed-off-by: David S.

There is a possibility malicious users can get limited information about uninitialized stack mem array. Even if sk_run_filter() result is bound to packet length (0 .. 65535), we could imagine this can be used by hostile user. Initializing mem[] array, like Dan Rosenberg suggested in his patch is expensive since most filters dont even use this array. Its hard to make the filter validation in sk_chk_filter(), because of the jumps. This might be done later. In this patch, I use a bitmap (a single long var) so that only filters using mem[] loads/stores pay the price of added security checks. For other filters, additional cost is a single instruction.

2010-11-09Bluetooth: Fix non-SSP auth request for HIGH security level socketsJohan Hedberg1-0/+6
When initiating dedicated bonding a L2CAP raw socket with HIGH security level is used. The kernel is supposed to trigger the authentication request in this case but this doesn't happen currently for non-SSP (pre-2.1) devices. The reason is that the authentication request happens in the remote extended features callback which never gets called for non-SSP devices. This patch fixes the issue by requesting also authentiation in the (normal) remote features callback in the case of non-SSP devices. This rule is applied only for HIGH security level which might at first seem unintuitive since on the server socket side MEDIUM is already enough for authentication. However, for the clients we really want to prefer the server side to decide the authentication requrement in most cases, and since most client sockets use MEDIUM it's better to be avoided on the kernel side for these sockets. The important socket to request it for is the dedicated bonding one and that socket uses HIGH security level. The patch is based on the initial investigation and patch proposal from Andrei Emeltchenko <endrei.emeltchenko@nokia.com>.

2010-11-08mac80211: unset SDATA_STATE_OFFCHANNEL when cancelling a scanBrian Cavagnolo1-3/+3
For client STA interfaces, ieee80211_do_stop unsets the relevant interface's SDATA_STATE_RUNNING state bit prior to cancelling an interrupted scan. When ieee80211_offchannel_return is invoked as part of cancelling the scan, it doesn't bother unsetting the SDATA_STATE_OFFCHANNEL bit because it sees that the interface is down. Normally this doesn't matter because when the client STA interface is brought back up, it will probably issue a scan. But in some cases (e.g., the user changes the interface type while it is down), the SDATA_STATE_OFFCHANNEL bit will remain set. This prevents the interface queues from being started. So we cancel the scan before unsetting the SDATA_STATE_RUNNING bit. Signed-off-by: Brian Cavagnolo <brian@cozybit.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2010-11-08ipv6: fix overlap check for fragmentsShan Wei1-1/+1
The type of FRAG6_CB(prev)->offset is int, skb->len is *unsigned* int, and offset is int. Without this patch, type conversion occurred to this expression, when (FRAG6_CB(prev)->offset + prev->len) is less than offset.

2010-11-08classifier: report statistics for basic classifierstephen hemminger1-0/+4
The basic classifier keeps statistics but does not report it to user space. This showed up when using basic classifier (with police) as a default catch all on ingress; no statistics were reported.
