* ipv6: Fix ipv6_getsockopt for IPV6_2292PKTOPTIONSDaniel Baluta2011-08-191-4/+5
| | | | | | | | | | | | | IPV6_2292PKTOPTIONS is broken for 32-bit applications running in COMPAT mode on 64-bit kernels. The same problem was fixed for IPv4 with the patch: ipv4: Fix ip_getsockopt for IP_PKTOPTIONS, commit dd23198e58cd35259dd09e8892bbdb90f1d57748 Signed-off-by: Sorin Dumitru <sdumitru@ixiacom.com> Signed-off-by: Daniel Baluta <dbaluta@ixiacom.com> Signed-off-by: David S.

* vlan: reset headers on accel emulation pathJiri Pirko2011-08-181-0/+2
| | | | | | | | | | | | | | It's after all necessary to do reset headers here. The reason is we cannot depend that it gets reseted in __netif_receive_skb once skb is reinjected. For incoming vlanids without vlan_dev, vlan_do_receive() returns false with skb != NULL and __netif_reveive_skb continues, skb is not reinjected.

* sit tunnels: propagate IPv6 transport class to IPv4 Type of ServiceLionel Elie Mamane2011-08-161-0/+3
| | | | | | | | | | | | | | | sit tunnels (IPv6 tunnel over IPv4) do not implement the "tos inherit" case to copy the IPv6 transport class byte from the inner packet to the IPv4 type of service byte in the outer packet. By contrast, ipip tunnels and GRE tunnels do. This patch, adapted from the similar code in net/ipv4/ipip.c and net/ipv4/ip_gre.c, implements that. This patch applies to 3.0.1, and has been tested on that version. Signed-off-by: Lionel Elie Mamane <lionel@mamane.lu> Signed-off-by: David S. Miller <davem@davemloft.net>
* ipv4: some rt_iif -> rt_route_iif conversionsJulian Anastasov2011-08-111-5/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | As rt_iif represents input device even for packets coming from loopback with output route, it is not an unique key specific to input routes. Now rt_route_iif has such role, it was fl.iif in 2.6.38, so better to change the checks at some places to save CPU cycles and to restore 2.6.38 semantics. compare_keys: - input routes: only rt_route_iif matters, rt_iif is same - output routes: only rt_oif matters, rt_iif is not used for matching in __ip_route_output_key - now we are back to 2.6.38 state ip_route_input_common: - matching rt_route_iif implies input route - compared to 2.6.38 we eliminated one rth->fl.oif check because it was not needed even for 2.6.38 compare_hash_inputs: Only the change here is not an optimization, it has effect only for output routes. I assume I'm restoring the original intention to ignore oif, it was using fl.iif - now we are back to 2.6.38 state Signed-off-by: Julian Anastasov <ja@ssi.bg> Signed-off-by: David S.

* net_sched: prio: use qdisc_dequeue_peekedFlorian Westphal2011-08-091-1/+1
| | | | | | | | | | | | | | | | | | | | | | commit 07bd8df5df4369487812bf85a237322ff3569b77 (sch_sfq: fix peek() implementation) changed sfq to use generic peek helper. This makes HFSC complain about a non-work-conserving child qdisc, if prio with sfq child is used within hfsc: hfsc peeks into prio qdisc, which will then peek into sfq. returned skb is stashed in sch->gso_skb. Next, hfsc tries to dequeue from prio, but prio will call sfq dequeue directly, which may return NULL instead of previously peeked-at skb. Have prio call qdisc_dequeue_peeked, so sfq->dequeue() is not called in this case. Cc: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: David S.

* netfilter: TCP and raw fix for ip_route_me_harderJulian Anastasov2011-08-071-10/+8
| | | | | | | | | | | | | | | | | | | TCP in some cases uses different global (raw) socket to send RST and ACK. The transparent flag is not set there. Currently, it is a problem for rerouting after the previous change. Fix it by simplifying the checks in ip_route_me_harder and use FLOWI_FLAG_ANYSRC even for sockets. It looks safe because the initial routing allowed this source address to be used and now we just have to make sure the packet is rerouted. As a side effect this also allows rerouting for normal raw sockets that use spoofed source addresses which was not possible even before we eliminated the ip_route_input call.

| | | | | | | | | | | | | | | | | | | | compare_keys and ip_route_input_common rely on rt_oif for distinguishing of input and output routes with same keys values. But sometimes the input route has also same hash chain (keyed by iif != 0) with the output routes (keyed by orig_oif=0). Problem visible if running with small number of rhash_entries. Fix them to use rt_route_iif instead. By this way input route can not be returned to users that request output route.

* net: Compute protocol sequence numbers and fragment IDs using MD5.David S. Miller2011-08-0611-8/+195
| | | | | | | | | | | | | | | | | | | | Computers have become a lot faster since we compromised on the partial MD4 hash which we use currently for performance reasons. MD5 is a much safer choice, and is inline with both RFC1948 and other ISS generators (OpenBSD, Solaris, etc.) Furthermore, only having 24-bits of the sequence number be truly unpredictable is a very serious limitation. So the periodic regeneration and 8-bit counter have been removed. We compute and use a full 32-bit sequence number. For ipv6, DCCP was found to use a 32-bit truncated initial sequence number (it needs 43-bits) and that is fixed here as well.

| | | | | | | | | | | | | | | When support for binding to 'mapped INADDR_ANY (::ffff.0.0.0.0)' was added in 0f8d3c7ac3693d7b6c731bf2159273a59bf70e12 the rest of the code wasn't told so now it's possible to bind IPv6 datagram socket to ::ffff.0.0.0.0, connect it to another IPv4 address and it will all work except for getsockhame() which does not return the local address as expected. To give getsockname() something to work with check for 'mapped INADDR_ANY' when connecting and update the in-core source addresses appropriately.

* net: Fix security_socket_sendmsg() bypass problem.Tetsuo Handa2011-08-051-9/+34
| | | | | | | | | | | | | | | | | | | | | | The sendmmsg() introduced by commit 228e548e "net: Add sendmmsg socket system call" is capable of sending to multiple different destination addresses. SMACK is using destination's address for checking sendmsg() permission. However, security_socket_sendmsg() is called for only once even if multiple different destination addresses are passed to sendmmsg(). Therefore, we need to call security_socket_sendmsg() for each destination address rather than only the first destination address. Since calling security_socket_sendmsg() every time when only single destination address was passed to sendmmsg() is a waste of time, omit calling security_socket_sendmsg() unless destination address of previous datagram and that of current datagram differs.

* net: Cap number of elements for sendmmsgAnton Blanchard2011-08-051-0/+3
| | | | | | | | | | | | | To limit the amount of time we can spend in sendmmsg, cap the number of elements to UIO_MAXIOV (currently 1024). For error handling an application using sendmmsg needs to retry at the first unsent message, so capping is simpler and requires less application logic than returning EINVAL.

* net: sendmmsg should only return an error if no messages were sentAnton Blanchard2011-08-051-24/+3
| | | | | | | | | | | | | | | | | | | | | sendmmsg uses a similar error return strategy as recvmmsg but it turns out to be a confusing way to communicate errors. The current code stores the error code away and returns it on the next sendmmsg call. This means a call with completely valid arguments could get an error from a previous call. Change things so we only return an error if no datagrams could be sent. If less than the requested number of messages were sent, the application must retry starting at the first failed one and if the problem is persistent the error will be returned. This matches the behaviour of other syscalls like read/write - it is not an error if less than the requested number of elements are sent.

It appears commit f39925dbde778 (ipv4: Cache learned redirect information in inetpeer.) added a race, leading to possible NULL ptr dereference. Since we can now change dst neighbour, we should make sure a reader can safely use a neighbour. Add RCU protection to dst neighbour, and make sure check_peer_redir() can be called safely by different cpus in parallel. As neighbours are already freed after one RCU grace period, this patch should not add typical RCU penalty (cache cold effects) Many thanks to Gergely for providing a pretty report pointing to the bug.

Then the request is sent to the driver nevertheless. This happens even if last_request points to NULL, leading to a crash in the driver: [<bf01d864>] (lbs_set_11d_domain_info+0x28/0x1e4 [libertas]) from [<c03b714c>] (wiphy_update_regulatory+0x4d0/0x4f4) [<c03b714c>] (wiphy_update_regulatory+0x4d0/0x4f4) from [<c03b4008>] (wiphy_register+0x354/0x420) [<c03b4008>] (wiphy_register+0x354/0x420) from [<bf01b17c>] (lbs_cfg_register+0x80/0x164 [libertas]) [<bf01b17c>] (lbs_cfg_register+0x80/0x164 [libertas]) from [<bf020e64>] (lbs_start_card+0x20/0x88 [libertas]) [<bf020e64>] (lbs_start_card+0x20/0x88 [libertas]) from [<bf02cbd8>] (if_sdio_probe+0x898/0x9c0 [libertas_sdio]) Fix this by returning early.

"Disable router anycast address for /127 prefixes" says: | No need for matching code in addrconf_leave_anycast() as it | will silently ignore any attempt to leave an unknown anycast | address. After analysis, because 1) we may add two or more prefixes on the same interface, or 2)user may have manually joined that anycast, we may hit chances to have anycast address which as if we had generated one by /127 prefix and we should not leave from subnet- router anycast address unconditionally.
