* [DECNET]: Fix for routing bugPatrick Caulfield2006-08-02
| | | | | | | | | | | This patch fixes a bug in the DECnet routing code where we were selecting a loopback device in preference to an outward facing device even when the destination was known non-local. This patch should fix the problem. Signed-off-by: Patrick Caulfield <patrick@tykepenguin.com> Signed-off-by: Steven Whitehouse <steve@chygwyn.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* [AF_UNIX]: Kernel memory leak fix for af_unix datagram getpeersec patchCatherine Zhang2006-08-02
| | | | | | | | | | | | | | | | | | | | From: Catherine Zhang <cxzhang@watson.ibm.com> This patch implements a cleaner fix for the memory leak problem of the original unix datagram getpeersec patch. Instead of creating a security context each time a unix datagram is sent, we only create the security context when the receiver requests it. This new design requires modification of the current unix_getsecpeer_dgram LSM hook and addition of two new hooks, namely, secid_to_secctx and release_secctx. The former retrieves the security context and the latter releases it. A hook is required for releasing the security context because it is up to the security module to decide how that's done. In the case of Selinux, it's a simple kfree operation. Acked-by: Stephen Smalley <sds@tycho.nsa.gov> Signed-off-by: David S. Miller <davem@davemloft.net>

* [IPV6]: SNMPv2 "ipv6IfStatsOutFragCreates" counter errorWei Dong2006-08-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When I tested linux kernel 2.6.71.7 about statistics "ipv6IfStatsOutFragCreates", and found that it couldn't increase correctly. The criteria is RFC 2465: ipv6IfStatsOutFragCreates OBJECT-TYPE SYNTAX Counter32 MAX-ACCESS read-only STATUS current DESCRIPTION "The number of output datagram fragments that have been generated as a result of fragmentation at this output interface." ::= { ipv6IfStatsEntry 15 } I think there are two issues in Linux kernel. 1st: RFC2465 specifies the counter is "The number of output datagram fragments...". I think increasing this counter after output a fragment successfully is better. And it should not be increased even though a fragment is created but failed to output. 2nd: If we send a big ICMP/ICMPv6 echo request to a host, and receive ICMP/ICMPv6 echo reply consisted of some fragments. As we know that in Linux kernel first fragmentation occurs in ICMP layer(maybe saying transport layer is better), but this is not the "real" fragmentation,just do some "pre-fragment" -- allocate space for date, and form a frag_list, etc. The "real" fragmentation happens in IP layer -- set offset and MF flag and so on. So I think in "fast path" for ip_fragment/ip6_fragment, if we send a fragment which "pre-fragment" by upper layer we should also increase "ipv6IfStatsOutFragCreates".

* [NET]: Kill the WARN_ON() calls for checksum fixups.David S. Miller2006-08-02
| | | | | | | | | | | | | | | | | We have a more complete solution in the works, involving the seperation of CHECKSUM_HW on input vs. output, and having netfilter properly do incremental checksums. But that is a very involved patch and is thus 2.6.19 material. What we have now is infinitely better than the past, wherein all TSO packets were dropped due to corrupt checksums as soon at the NAT module was loaded. At least now, the checksums do get fixed up, it just isn't the cleanest nor most optimal solution. Signed-off-by: David S. Miller <davem@davemloft.net>

* [TCP]: Process linger2 timeout consistently.David S. Miller2006-08-02
| | | | | | | | | | | | | | | | | | | Based upon guidance from Alexey Kuznetsov. When linger2 is active, we check to see if the fin_wait2 timeout is longer than the timewait. If it is, we schedule the keepalive timer for the difference between the timewait timeout and the fin_wait2 timeout. When this orphan socket is seen by tcp_keepalive_timer() it will try to transform this fin_wait2 socket into a fin_wait2 mini-socket, again if linger2 is active. Not all paths were setting this initial keepalive timer correctly. The tcp input path was doing it correctly, but tcp_close() wasn't, potentially making the socket linger longer than it really needs to. Signed-off-by: David S. Miller <davem@davemloft.net>
* [SECURITY] secmark: nul-terminate secdataJames Morris2006-08-02
| | | | | | | | | | | | | | | | | The patch below fixes a problem in the iptables SECMARK target, where the user-supplied 'selctx' string may not be nul-terminated. From initial analysis, it seems that the strlen() called from selinux_string_to_sid() could run until it arbitrarily finds a zero, and possibly cause a kernel oops before then. The impact of this appears limited because the operation requires CAP_NET_ADMIN, which is essentially always root. Also, the module is not yet in wide use.

* [IPV6]: Audit all ip6_dst_lookup/ip6_dst_store callsHerbert Xu2006-08-02
| | | | | | | | | | | | | | | | | | | The current users of ip6_dst_lookup can be divided into two classes: 1) The caller holds no locks and is in user-context (UDP). 2) The caller does not want to lookup the dst cache at all. The second class covers everyone except UDP because most people do the cache lookup directly before calling ip6_dst_lookup. This patch adds ip6_sk_dst_lookup for the first class. Similarly ip6_dst_store users can be divded into those that need to take the socket dst lock and those that don't. This patch adds __ip6_dst_store for those (everyone except UDP/datagram) that don't need an extra lock. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.
