2013-10-22Revert "bridge: only expire the mdb entry when query is received"Linus Lüssing3-22/+28
While this commit was a good attempt to fix issues occuring when no multicast querier is present, this commit still has two more issues: 1) There are cases where mdb entries do not expire even if there is a querier present. The bridge will unnecessarily continue flooding multicast packets on the according ports. 2) Never removing an mdb entry could be exploited for a Denial of Service by an attacker on the local link, slowly, but steadily eating up all memory. Actually, this commit became obsolete with "bridge: disable snooping if there is no querier" (b00589af3b) which included fixes for a few more cases. Therefore reverting the following commits (the commit stated in the commit message plus three of its follow up fixes): ==================== Revert "bridge: update mdb expiration timer upon reports." This reverts commit f144febd93d5ee534fdf23505ab091b2b9088edc. Revert "bridge: do not call setup_timer() multiple times" This reverts commit 1faabf2aab1fdaa1ace4e8c829d1b9cf7bfec2f1.

2013-10-21tcp: initialize passive-side sk_pacing_rate after 3WHSNeal Cardwell1-0/+2
For passive TCP connections, upon receiving the ACK that completes the 3WHS, make sure we set our pacing rate after we get our first RTT sample. On passive TCP connections, when we receive the ACK completing the 3WHS we do not take an RTT sample in tcp_ack(), but rather in tcp_synack_rtt_meas(). So upon receiving the ACK that completes the 3WHS, tcp_ack() leaves sk_pacing_rate at its initial value. Originally the initial sk_pacing_rate value was 0, so passive-side connections defaulted to sysctl_tcp_min_tso_segs (2 segs) in skbuffs made in the first RTT. With a default initial cwnd of 10 packets, this happened to be correct for RTTs 5ms or bigger, so it was hard to see problems in WAN or emulated WAN testing. Since 7eec4174ff ("pkt_sched: fq: fix non TCP flows pacing"), the initial sk_pacing_rate is 0xffffffff. So after that change, passive TCP connections were keeping this value (and using large numbers of segments per skbuff) until receiving an ACK for data.

2013-10-21davinci_emac.c: Fix IFF_ALLMULTI setupMariusz Ceier1-2/+1
When IFF_ALLMULTI flag is set on interface and IFF_PROMISC isn't, emac_dev_mcast_set should only enable RX of multicasts and reset MACHASH registers. It does this, but afterwards it either sets up multicast MACs filtering or disables RX of multicasts and resets MACHASH registers again, rendering IFF_ALLMULTI flag useless. This patch fixes emac_dev_mcast_set, so that multicast MACs filtering and disabling of RX of multicasts are skipped when IFF_ALLMULTI flag is set. Tested with kernel 2.6.37.

2013-10-21Merge branch 'rt6i_gateway'David S. Miller4-10/+12
Julian Anastasov says: ==================== ipv6: use rt6i_gateway as nexthop The following patchset makes sure that rt6i_gateway contains valid nexthop information in all cases, so that we can use different nexthop for sending. The first patch is a simple fix that makes IPVS, TEE, RAW(hdrincl) and RTF_DYNAMIC(without RTF_GATEWAY) work as before 3.9. There is a single corner case not solved by this patch: RAW(hdrincl) or TEE using local address for nexthop, a silly feature, I guess. In this case we see zeroes in rt6i_gateway because we get route that is not cloned. This is solved only with patch 2. The second patch is an optimization that makes sure all resulting routes have rt6i_gateway filled, so that we can avoid the complex ipv6_addr_any() call added to rt6_nexthop() by patch 1. And it sets rt6i_gateway for local routes, a case not handled by patch 1. The third patch uses the new rt6_nexthop() function to fix the matching of gateways in the same way as commit bbb5823cf742a7 ("netfilter: nf_conntrack: fix rt_gateway checks for H.323 helper") fixes nf_conntrack_h323_main.c for IPv4. Currently, it depends on the new definition of rt6_nexthop() in patch 2. Actually, if patch 2 is applied, patch 3 becomes a cosmetic change. I see the following two alternatives for applying these patches: 1. Linger patch 2 in net-next to avoid surprises in the upcoming release. In this case patch 3 can be reworked not to depend on the new rt6_nexthop() definition in patch 2. I guess this is a better option, so that patch 2 can be reviewed and tested for longer time. 2. Include all 3 patches in net tree - more risky because this is my first attempt to change IPv6. Here is the situation as handled by patch 2: In IPv6 the resolved routes are always host routes (/128 with DST_HOST), mostly cloned ones. We allow routes in FIB to contain rt6i_gateway with zeroes (eg. for local subnets) but on cloning we can fill the rt6i_gateway field in result. This works even without this patchset. There is a single special case where dst is provided as skb_dst directly without a routing call: icmp6_dst_alloc(). It is a private dst allocated just for the particular ICMP packet. Patch 2 fills rt6i_gateway in this case, needed for the new rt6_nexthop() simplification. The last case is addrconf_dst_alloc(), it can put in FIB local/anycast routes when addresses are added. Patch 2 needs to fill rt6i_gateway in this case because such routes are returned without cloning. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2013-10-21ipv6: always prefer rt6i_gateway if presentJulian Anastasov1-1/+1
In v3.9 6fd6ce2056de2709 ("ipv6: Do not depend on rt->n in ip6_finish_output2()." changed the behaviour of ip6_finish_output2() such that the recently introduced rt6_nexthop() is used instead of an assigned neighbor. As rt6_nexthop() prefers rt6i_gateway only for gatewayed routes this causes a problem for users like IPVS, xt_TEE and RAW(hdrincl) if they want to use different address for routing compared to the destination address. Another case is when redirect can create RTF_DYNAMIC route without RTF_GATEWAY flag, we ignore the rt6i_gateway in rt6_nexthop(). Fix the above problems by considering the rt6i_gateway if present, so that traffic routed to address on local subnet is not wrongly diverted to the destination address.

2013-10-21bnx2x: Don't pretend during register dumpDmitry Kravkov3-205/+201
As part of a register dump, the interface pretends to have the identity of other interfaces of the same physical device in order to perform HW configuration for them - specifically, it needs to prevent attentions from generating on those functions as the register dump accesses registers in common blocks which whose reading might generate an attention. However, such pretension is unsafe - unlike other flows in which the driver uses pretend, during register dump there is no guarantee no other HW access will take place (by other flows). If such access will take place, the HW will be accessed by the wrong interface, and leave both functions in an incorrect state. This patch removes all pretensions from the register dump flow. Instead, it changes initial configuration of attentions such that no fatal attention will be generated for other functions as a result of the register dump (notice however, a debug print claiming an attention from other functions IS possible during the register dump) Signed-off-by: Dmitry Kravkov <dmitry@broadcom.com> Signed-off-by: Yuval Mintz <yuvalmin@broadcom.com> Signed-off-by: Ariel Elior <ariele@broadcom.com> Signed-off-by: Eilon Greenstein <eilong@broadcom.com> Signed-off-by: David S.

2013-10-21bnx2x: Lock DMAE when used by statistic flowAriel Elior4-10/+11
bnx2x has several clients to its DMAE machines - all of them with the exception of the statistics flow used the same locking mechanisms to synchronize the DMAE machines' usage. Since statistics (which are periodically entered) use DMAE without taking the locks, they may erase the commands which were previously set - e.g., it may cause a VF to timeout while waiting for a PF answer on the VF-PF channel as that command header would have been overwritten by the statistics' header. This patch makes certain that all flows utilizing DMAE will use the same API, assuring that the locking scheme will be kept by all said flows.

2013-10-21bnx2x: Prevent an illegal pointer dereference during panicYuval Mintz2-7/+29
During a panic, the driver tries to print the Management FW buffer of recent commands. To do so, the driver reads the address of that buffer from a known address. If the buffer is unavailable (e.g., PCI reads don't work, MCP is failing, etc.), the driver will try to access the address it has read, possibly causing a kernel panic. This check 'sanitizes' the access, validating the read value is indeed a valid address inside the management FW's buffers. The patch also removes a read outside the scope of the buffer, which resulted in some unrelated chraracters appearing in the log.

2013-10-19net: unix: inherit SOCK_PASS{CRED, SEC} flags from socket to fix raceDaniel Borkmann1-0/+10
In the case of credentials passing in unix stream sockets (dgram sockets seem not affected), we get a rather sparse race after commit 16e5726 ("af_unix: dont send SCM_CREDENTIALS by default"). We have a stream server on receiver side that requests credential passing from senders (e.g. nc -U). Since we need to set SO_PASSCRED on each spawned/accepted socket on server side to 1 first (as it's not inherited), it can happen that in the time between accept() and setsockopt() we get interrupted, the sender is being scheduled and continues with passing data to our receiver. At that time SO_PASSCRED is neither set on sender nor receiver side, hence in cmsg's SCM_CREDENTIALS we get eventually pid:0, uid:65534, gid:65534 (== overflow{u,g}id) instead of what we actually would like to see. On the sender side, here nc -U, the tests in maybe_add_creds() invoked through unix_stream_sendmsg() would fail, as at that exact time, as mentioned, the sender has neither SO_PASSCRED on his side nor sees it on the server side, and we have a valid 'other' socket in place. Thus, sender believes it would just look like a normal connection, not needing/requesting SO_PASSCRED at that time. As reverting 16e5726 would not be an option due to the significant performance regression reported when having creds always passed, one way/trade-off to prevent that would be to set SO_PASSCRED on the listener socket and allow inheriting these flags to the spawned socket on server side in accept(). It seems also logical to do so if we'd tell the listener socket to pass those flags onwards, and would fix the race.
