physoutdev is only set on purely bridged packet, when nfnetlink_log is used in the OUTPUT/FORWARD/POSTROUTING hooks on packets forwarded from or to a bridge it crashes when trying to dereference skb->nf_bridge->physoutdev. Reported by Holger Eitzenberger <heitzenberger@astaro.com> Signed-off-by:

The individual fragments of a packet reassembled by conntrack have the conntrack reference from the reassembled packet attached, but nfctinfo is not copied. This leaves it initialized to 0, which unfortunately is the value of IP_CT_ESTABLISHED. The result is that all IPv6 fragments are tracked as ESTABLISHED, allowing them to bypass a usual ruleset which accepts ESTABLISHED packets early. Signed-off-by:

When the packet counter of a connection is zero a division by zero occurs in div64_64(). Fix that by using zero as average value, which is correct as long as the packet counter didn't overflow, at which point we have lost anyway.

When IPv6 connection tracking splits up a defragmented packet into its original fragments, the packets are taken from a list and are passed to the network stack with skb->next still set. This causes dev_hard_start_xmit to treat them as GSO fragments, resulting in a use after free when connection tracking handles the next fragment. Signed-off-by:

With the introduction of x_tables we accidentally broke compatibility by defining IPT_TABLE_MAXNAMELEN to XT_FUNCTION_MAXNAMELEN instead of XT_TABLE_MAXNAMELEN, which is two bytes larger. On most architectures it doesn't really matter since we don't have any tables with names that long in the kernel and the structure layout didn't change because of alignment requirements of following members. On CRIS however (and other architectures that don't align data) this changed the structure layout and thus broke compatibility with old iptables binaries. Changing it back will break compatibility with binaries compiled against recent kernels again, but since the breakage has only been there for three releases this seems like the better choice.

Invoking load_module() before param_sysfs_init() is called crashes in mod_sysfs_setup(), since the kset in module_subsys is not initialized yet. In my case, net-pf-1 is getting modprobed as a result of hotplug trying to create a UNIX socket. Calls to hotplug begin after the topology_init initcall. Another patch for the same symptom (module_subsys-initialize-earlier.patch) moves param_sysfs_init() to the subsys initcalls, but this is still not early enough in the boot process in some cases. In particular, topology_init() causes /sbin/hotplug to run, which requests net-pf-1 (the UNIX socket protocol) which can be compiled as a module. Moving param_sysfs_init() to the postcore initcalls fixes this particular race, but there might well be other cases where a usermodehelper causes a module to load earlier still. The patch makes load_module() return an error rather than crashing the kernel if invoked before module_subsys is initialized. Signed-off-by: -

The ipv6_fl_socklist from listening socket is inadvertently shared with new socket created for connection. This leads to a variety of interesting, but fatal, bugs. For example, removing one of the sockets may lead to the other socket's encountering a page fault when the now freed list is referenced. The fix is to not share the flow label list with the new socket. Signed-off-by:

Hello, Just discussed this Patrick... We have two users of trie_leaf_remove, fn_trie_flush and fn_trie_delete both are holding RTNL. So there shouldn't be need for this preempt stuff. This is assumed to a leftover from an older RCU-take. > Mhh ..

I noticed that in xfrm_state_add we look for the larval SA in a few places without checking for protocol match. So when using both AH and ESP, whichever one gets added first, deletes the larval SA. It seems AH always gets added first and ESP is always the larval SA's protocol since the xfrm->tmpl has it first. Thus causing the additional km_query() Adding the check eliminates accidental double SA creation. Signed-off-by:

Based on a patch from Don Howard <dhoward@redhat.com> When calling write() with a buffer larger than 512 bytes, the driver's write buffer overflows, allowing to overwrite the EIP and execute arbitrary code with kernel privileges. In read(), there exists a similar problem, but coming from the device. A malicous or buggy device sending more than 512 bytes can overflow of the driver's read buffer, with the same effects as above.

From: Michael S. Tsirkin <mst@mellanox.co.il> mthca_table_find() will return the wrong address when the table entry being searched for is exactly at the beginning of a sglist entry (other than the first), because it uses >= when it should use >. Example: assume we have 2 entries in scatterlist, 4K each, offset is 4K. The current code will return first entry + 4K when we really want the second entry. In particular this means mapping an FMR on a memfree HCA may end up writing the page table into the wrong place, leading to memory corruption and also causing the HCA to use an incorrect address translation table.

When ipoib_ib_dev_flush() is called because of a port event, the driver needs to rejoin all multicast groups, since the flush will call ipoib_mcast_dev_flush() (via ipoib_ib_dev_down()). Otherwise no (non-broadcast) multicast groups will be rejoined until the networking core calls ->set_multicast_list again, and so multicast reception will be broken for potentially a long time.

We discovered a problem when running IPoIB applications on multiple CPUs on an Altix system. Many messages such as: ib_mthca 0002:01:00.0: SQ 000014 full (19941644 head, 19941707 tail, 64 max, 0 nreq) appear in syslog, and the driver wedges up. Apparently this is because writes to the doorbells from different CPUs reach the device out of order. The following patch adds mmiowb() calls after doorbell rings to ensure the doorbell writes are ordered. Signed-off-by:
