2008-06-16udp: add struct net argument to udp_hashfnPavel Emelyanov
Every caller already has this one. The new argument is currently unused, but this will be fixed shortly. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-06-16udp: provide a struct net pointer for __udp[46]_lib_mcast_deliverPavel Emelyanov
They both calculate the hash chain, but currently do not have a struct net pointer, so pass one there via additional argument, all the more so their callers already have such. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-06-16udp: introduce a udp_hashfn functionPavel Emelyanov
Currently the chain to store a UDP socket is calculated with simple (x & (UDP_HTABLE_SIZE - 1)). But taking net into account would make this calculation a bit more complex, so moving it into a function would help. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S.

2008-06-14mac80211: eliminate IBSS warning in rate_lowest_index()Vladimir Koutny
In IBSS mode prior to join/creation of new IBSS it is possible that a frame from unknown station is received and an ibss_add_sta() is called. This will cause a warning in rate_lowest_index() since the list of supported rates of our station is not initialized yet. The fix is to add ibss stations with a rate we received that frame at; this single-element set will be extended later based on beacon data. Also there is no need to store stations from a foreign IBSS. Signed-off-by: Vladimir Koutny <vlado@ksp.sk> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2008-06-12tcp: Revert 'process defer accept as established' changes.David S. Miller
This reverts two changesets, ec3c0982a2dd1e671bad8e9d26c28dcba0039d87 ("[TCP]: TCP_DEFER_ACCEPT updates - process as established") and the follow-on bug fix 9ae27e0adbf471c7a6b80102e38e1d5a346b3b38 ("tcp: Fix slab corruption with ipv6 and tcp6fuzz"). This change causes several problems, first reported by Ingo Molnar as a distcc-over-loopback regression where connections were getting stuck. Ilpo Järvinen first spotted the locking problems. The new function added by this code, tcp_defer_accept_check(), only has the child socket locked, yet it is modifying state of the parent listening socket. Fixing that is non-trivial at best, because we can't simply just grab the parent listening socket lock at this point, because it would create an ABBA deadlock. The normal ordering is parent listening socket --> child socket, but this code path would require the reverse lock ordering. Next is a problem noticed by Vitaliy Gusev, he noted: ---------------------------------------- >--- a/net/ipv4/tcp_timer.c >+++ b/net/ipv4/tcp_timer.c >@@ -481,6 +481,11 @@ static void tcp_keepalive_timer (unsigned long data) > goto death; > } > >+ if (tp->defer_tcp_accept.request && sk->sk_state == TCP_ESTABLISHED) { >+ tcp_send_active_reset(sk, GFP_ATOMIC); >+ goto death; Here socket sk is not attached to listening socket's request queue. tcp_done() will not call inet_csk_destroy_sock() (and tcp_v4_destroy_sock() which should release this sk) as socket is not DEAD. Therefore socket sk will be lost for freeing. ---------------------------------------- Finally, Alexey Kuznetsov argues that there might not even be any real value or advantage to these new semantics even if we fix all of the bugs: ---------------------------------------- Hiding from accept() sockets with only out-of-order data only is the only thing which is impossible with old approach. Is this really so valuable? My opinion: no, this is nothing but a new loophole to consume memory without control. ---------------------------------------- So revert this thing for now.

2008-06-12ipv6: Fix duplicate initialization of rawv6_prot.destroyDavid S. Miller
In changeset 22dd485022f3d0b162ceb5e67d85de7c3806aa20 ("raw: Raw socket leak.") code was added so that we flush pending frames on raw sockets to avoid leaks. The ipv4 part was fine, but the ipv6 part was not done correctly. Unlike the ipv4 side, the ipv6 code already has a .destroy method for rawv6_prot. So now there were two assignments to this member, and what the compiler does is use the last one, effectively making the ipv6 parts of that changeset a NOP. Fix this by removing the: .destroy = inet6_destroy_sock, line, and adding an inet6_destroy_sock() call to the end of raw6_destroy(). Noticed by Al Viro. Signed-off-by: David S.

When creation of a new conntrack entry in ctnetlink fails after having set up the NAT mappings, the conntrack has an extension area allocated that is not getting properly destroyed when freeing the conntrack again. This means the NAT extension is still in the bysource hash, causing a crash when walking over the hash chain the next time: BUG: unable to handle kernel paging request at 00120fbd IP: [<c03d394b>] nf_nat_setup_info+0x221/0x58a *pde = 00000000 Oops: 0000 [#1] PREEMPT SMP Pid: 2795, comm: conntrackd Not tainted (2.6.26-rc5 #1) EIP: 0060:[<c03d394b>] EFLAGS: 00010206 CPU: 1 EIP is at nf_nat_setup_info+0x221/0x58a EAX: 00120fbd EBX: 00120fbd ECX: 00000001 EDX: 00000000 ESI: 0000019e EDI: e853bbb4 EBP: e853bbc8 ESP: e853bb78 DS: 007b ES: 007b FS: 00d8 GS: 0033 SS: 0068 Process conntrackd (pid: 2795, ti=e853a000 task=f7de10f0 task.ti=e853a000) Stack: 00000000 e853bc2c e85672ec 00000008 c0561084 63c1db4a 00000000 00000000 00000000 0002e109 61d2b1c3 00000000 00000000 00000000 01114e22 61d2b1c3 00000000 00000000 f7444674 e853bc04 00000008 c038e728 0000000a f7444674 Call Trace: [<c038e728>] nla_parse+0x5c/0xb0 [<c0397c1b>] ctnetlink_change_status+0x190/0x1c6 [<c0397eec>] ctnetlink_new_conntrack+0x189/0x61f [<c0119aee>] update_curr+0x3d/0x52 [<c03902d1>] nfnetlink_rcv_msg+0xc1/0xd8 [<c0390228>] nfnetlink_rcv_msg+0x18/0xd8 [<c0390210>] nfnetlink_rcv_msg+0x0/0xd8 [<c038d2ce>] netlink_rcv_skb+0x2d/0x71 [<c0390205>] nfnetlink_rcv+0x19/0x24 [<c038d0f5>] netlink_unicast+0x1b3/0x216 ...

This pacth makes IPv6 address labels per network namespace. It keeps the global label tables, ip6addrlbl_table, but adds a 'net' member to each ip6addrlbl_entry. This new member is taken into account when matching labels. Changelog ========= * v1: Initial version * v2: * Minize the penalty when network namespaces are not configured: * the 'net' member is added only if CONFIG_NET_NS is defined. This saves space when network namespaces are not configured. * 'net' value is retrieved with the inlined function ip6addrlbl_net() that always return &init_net when CONFIG_NET_NS is not defined. * 'net' member in ip6addrlbl_entry renamed to the less generic 'lbl_net' name (helps code search).

2008-06-11dccp ccid-3: X truncated due to type conversionGerrit Renker

2008-06-11dccp ccid-3: TFRC reverse-lookup Bug-FixGerrit Renker
This fixes a bug in the reverse lookup of p: given a value f(p), instead of p, the function returned the smallest tabulated value f(p). The smallest tabulated value of 10^6 * f(p) = sqrt(2*p/3) + 12 * sqrt(3*p/8) * (32 * p^3 + p) for p=0.0001 is 8172. Since this value is scaled by 10^6, the outcome of this bug is that a loss of 8172/10^6 = 0.8172% was reported whenever the input was below the table resolution of 0.01%. This means that the value was over 80 times too high, resulting in large spikes of the initial loss interval, thus unnecessarily reducing the throughput. Also corrected the printk format (%u for u32). Signed-off-by: Gerrit Renker <gerrit@erg.abdn.ac.uk>
2008-06-11dccp ccid-2: Bug-Fix - Ack Vectors need to be ignored on request socketsGerrit Renker
This fixes an oversight from an earlier patch, ensuring that Ack Vectors are not processed on request sockets. The issue is that Ack Vectors must not be parsed on request sockets, since the Ack Vector feature depends on the selection of the (TX) CCID. During the initial handshake the CCIDs are undefined, and so RFC 4340, 10.3 applies: "Using CCID-specific options and feature options during a negotiation for the corresponding CCID feature is NOT RECOMMENDED [...]" And it is not even possible: when the server receives the Request from the client, the CCID and Ack vector features are undefined; when the Ack finalising the 3-way hanshake arrives, the request socket has not been cloned yet into a full socket. (This order is necessary, since otherwise the newly created socket would have to be destroyed whenever an option error occurred - a malicious hacker could simply send garbage options and exploit this.)
