* ipvs: Fix reuse connection if real server is deadGrzegorz Lyczba2013-05-271-0/+35
| | | | | | | | | | | | Expire cached connection for new TCP/SCTP connection if real server is down. Otherwise, IPVS uses the dead server for the reused connection, instead of a new working one.

* netfilter: ipt_ULOG: fix non-null terminated string in the nf_log pathChen Gang2013-05-231-2/+4
| | | | | | | | | | | | | If nf_log uses ipt_ULOG as logging output, we can deliver non-null terminated strings to user-space since the maximum length of the prefix that is passed by nf_log is NF_LOG_PREFIXLEN but pm->prefix is 32 bytes long (ULOG_PREFIX_LEN). This is actually happening already from nf_conntrack_tcp if ipt_ULOG is used, since it is passing strings longer than 32 bytes.

* netfilter: add nf_ipv6_ops hook to fix xt_addrtype with IPv6Florian Westphal2013-05-234-12/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Quoting https://bugzilla.netfilter.org/show_bug.cgi?id=812: [ ip6tables -m addrtype ] When I tried to use in the nat/PREROUTING it messes up the routing cache even if the rule didn't matched at all. [..] If I remove the --limit-iface-in from the non-working scenario, so just use the -m addrtype --dst-type LOCAL it works! This happens when LOCAL type matching is requested with --limit-iface-in, and the default ipv6 route is via the interface the packet we test arrived on. Because xt_addrtype uses ip6_route_output, the ipv6 routing implementation creates an unwanted cached entry, and the packet won't make it to the real/expected destination. Silently ignoring --limit-iface-in makes the routing work but it breaks rule matching (--dst-type LOCAL with limit-iface-in is supposed to only match if the dst address is configured on the incoming interface; without --limit-iface-in it will match if the address is reachable via lo). The test should call ipv6_chk_addr() instead. However, this would add a link-time dependency on ipv6. There are two possible solutions: 1) Revert the commit that moved ipt_addrtype to xt_addrtype, and put ipv6 specific code into ip6t_addrtype. 2) add new "nf_ipv6_ops" struct to register pointers to ipv6 functions. While the former might seem preferable, Pablo pointed out that there are more xt modules with link-time dependeny issues regarding ipv6, so lets go for 2).

* xfrm: properly handle invalid states as an errorTimo Teräs2013-05-231-0/+1

* tcp: bug fix in proportional rate reduction.Nandita Dukkipati2013-05-231-10/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is a fix for a bug triggering newly_acked_sacked < 0 in tcp_ack(.). The bug is triggered by sacked_out decreasing relative to prior_sacked, but packets_out remaining the same as pior_packets. This is because the snapshot of prior_packets is taken after tcp_sacktag_write_queue() while prior_sacked is captured before tcp_sacktag_write_queue(). The problem is: tcp_sacktag_write_queue (tcp_match_skb_to_sack() -> tcp_fragment) adjusts the pcount for packets_out and sacked_out (MSS change or other reason). As a result, this delta in pcount is reflected in (prior_sacked - sacked_out) but not in (prior_packets - packets_out). This patch does the following: 1) initializes prior_packets at the start of tcp_ack() so as to capture the delta in packets_out created by tcp_fragment. 2) introduces a new "previous_packets_out" variable that snapshots packets_out right before tcp_clean_rtx_queue, so pkts_acked can be correctly computed as before. 3) Computes pkts_acked using previous_packets_out, and computes newly_acked_sacked using prior_packets.

| | | | | | | | | | | On errors in batadv_mesh_init(), bat_counters will be freed in both batadv_mesh_free() and batadv_softif_init_late().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When an HT AP is advertising channel switch in a beacon, it doesn't (and shouldn't, according to 802.11-2012 Table 8-20) include a secondary channel offset element. The only possible interpretation is that the previous secondary channel offset remains valid, so use that when switching channel based only on beacon information. VHT requires the Wide Bandwidth Channel Switch subelement to be present in the Channel Switch Wrapper element, so the code for that is probably ok (see 802.11ac Draft 4, 8.4.2.165.)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 'discovery->data.info' length is 22, NICKNAME_MAX_LEN is 21, so the strncpy() will always left the last byte of 'discovery->data.info' uninitialized. When 'text' length is longer than 21 (NICKNAME_MAX_LEN), if still left the last byte of 'discovery->data.info' uninitialized, the next strlen() will cause issue. Also 'discovery->data' is 'struct irda_device_info' which defined in "include/uapi/...", it may copy to user mode, so need whole initialized.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The net/netlabel/netlabel_domainhash.c:netlbl_domhsh_add() function does not properly validate new domain hash entries resulting in potential problems when an administrator attempts to add an invalid entry. One such problem, as reported by Vlad Halilov, is a kernel BUG (found in netlabel_domainhash.c:netlbl_domhsh_audit_add()) when adding an IPv6 outbound mapping with a CIPSO configuration. This patch corrects this problem by adding the necessary validation code to netlbl_domhsh_add() via the newly created netlbl_domhsh_validate() function. Ideally this patch should also be pushed to the currently active -stable trees.

* | batman-adv: Fix rcu_barrier() miss due to double call_rcu() in TT codeLinus Lüssing2013-05-173-1/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | rcu_barrier() only waits for the currently scheduled rcu functions to finish - it won't wait for any function scheduled via another call_rcu() within an rcu scheduled function. Unfortunately our batadv_tt_orig_list_entry_free_ref() does just that, via a batadv_orig_node_free_ref() call, leading to our rcu_barrier() call potentially missing such a batadv_orig_node_free_ref(). This patch fixes this issue by calling the batadv_orig_node_free_rcu() directly from the rcu callback, removing the unnecessary, additional call_rcu() layer here.

* | tcp: gso: do not generate out of order packetsEric Dumazet2013-05-161-1/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | GSO TCP handler has following issues : 1) ooo_okay from original GSO packet is duplicated to all segments 2) segments (but the last one) are orphaned, so transmit path can not get transmit queue number from the socket. This happens if GSO segmentation is done before stacked device for example. Result is we can send packets from a given TCP flow to different TX queues (if using multiqueue NICS). This generates OOO problems and spurious SACK & retransmits. Fix this by keeping socket pointer set for all segments. This means that every segment must also have a destructor, and the original gso skb truesize must be split on all segments, to keep precise sk->sk_wmem_alloc accounting.

Bug was added in linux-2.6.29 when RCU lookups were introduced in UDP and TCP stacks. Once an IPv6 socket, using SLAB_DESTROY_BY_RCU is inserted in a hash table, we no longer can clear pinet6 field. This patch extends logic used in commit fcbdf09d9652c891 ("net: fix nulls list corruptions in sk_prot_alloc") TCP/UDP/UDPLite IPv6 protocols provide their own .clear_sk() method to make sure we do not clear pinet6 field. At socket clone phase, we do not really care, as cloning the parent (non NULL) pinet6 is not adding a fatal race. Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.

Fix this by killing the worker (in nc_free) before freeing the originator table. Moreover tidy up the entire clean up routine by running all the subcomponents freeing procedures first and then killing the TT and the originator tables at the end.
