* [NETNS]: icmp(v6)_sk should not pin a namespace.Denis V. Lunev2008-02-291-6/+5
| | | | | | | | | | | | | So, change icmp(v6)_sk creation/disposal to the scheme used in the netlink for rtnl, i.e. create a socket in the context of the init_net and assign the namespace without getting a referrence later. Also use sk_release_kernel instead of sock_release to properly destroy such sockets. Signed-off-by: Denis V.

* [ICMP]: Allocate data for __icmp(v6)_sk dynamically.Denis V. Lunev2008-02-291-5/+9
| | | | | | | | | | | | | Own __icmp(v6)_sk should be present in each namespace. So, it should be allocated dynamically. Though, alloc_percpu does not fit the case as it implies additional dereferrence for no bonus.

| | | | | | | | | | | | | | | | | | | | We have to get socket lock inside icmp(v6)_xmit_lock/unlock. The socket is get from global variable now. When this code became namespaces, one should pass a namespace and get socket from it. Though, above is useless. Socket is available in the caller, just pass it inside.

| | | | | | | | | | | This patch moves the icmpv6_time sysctl to the network namespace structure.

* [NETNS][IPV6]: Make multiple instance of sysctl tables.Daniel Lezcano2008-01-281-1/+11
| | | | | | | | | | | | | Each network namespace wants its own set of sysctl value, eg. we should not be able from a namespace to set a sysctl value for another namespace , especially for the initial network namespace.

* [IPSEC]: Add ICMP host relookup supportHerbert Xu2008-01-281-4/+56
| | | | | | | | | | | | | | | RFC 4301 requires us to relookup ICMP traffic that does not match any policies using the reverse of its payload. This patch implements this for ICMP traffic that originates from or terminates on localhost. This is activated on outbound with the new policy flag XFRM_POLICY_ICMP, and on inbound by the new state flag XFRM_STATE_ICMP. On inbound the policy check is now performed by the ICMP protocol so that it can repeat the policy check where necessary.

* [IPV6]: Add ICMPMsgStats MIB (RFC 4293) [rev 2]David L Stevens2007-10-101-9/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Background: RFC 4293 deprecates existing individual, named ICMP type counters to be replaced with the ICMPMsgStatsTable. This table includes entries for both IPv4 and IPv6, and requires counting of all ICMP types, whether or not the machine implements the type. These patches "remove" (but not really) the existing counters, and replace them with the ICMPMsgStats tables for v4 and v6. It includes the named counters in the /proc places they were, but gets the values for them from the new tables. It also counts packets generated from raw socket output (e.g., OutEchoes, MLD queries, RA's from radvd, etc). Changes: 1) create icmpmsg_statistics mib 2) create icmpv6msg_statistics mib 3) modify existing counters to use these 4) modify /proc/net/snmp to add "IcmpMsg" with all ICMP types listed by number for easy SNMP parsing 5) modify /proc/net/snmp printing for "Icmp" to get the named data from new counters. [new to 2nd revision] 6) support per-interface ICMP stats 7) use common macro for per-device stat macros Signed-off-by: David L Stevens <dlstevens@us.ibm.com> Signed-off-by: David S.

* [IPV6]: MSG_ERRQUEUE messages do not pass to connected raw socketsDmitry Butskoy2007-07-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From: Dmitry Butskoy <dmitry@butskoy.name> Taken from http://bugzilla.kernel.org/show_bug.cgi?id=8747 Problem Description: It is related to the possibility to obtain MSG_ERRQUEUE messages from the udp and raw sockets, both connected and unconnected. There is a little typo in net/ipv6/icmp.c code, which prevents such messages to be delivered to the errqueue of the correspond raw socket, when the socket is CONNECTED. The typo is due to swap of local/remote addresses. Consider __raw_v6_lookup() function from net/ipv6/raw.c. When a raw socket is looked up usual way, it is something like: sk = __raw_v6_lookup(sk, nexthdr, daddr, saddr, IP6CB(skb)->iif); where "daddr" is a destination address of the incoming packet (IOW our local address), "saddr" is a source address of the incoming packet (the remote end). But when the raw socket is looked up for some icmp error report, in net/ipv6/icmp.c:icmpv6_notify() , daddr/saddr are obtained from the echoed fragment of the "bad" packet, i.e. "daddr" is the original destination address of that packet, "saddr" is our local address. Hence, for icmpv6_notify() must use "saddr, daddr" in its arguments, not "daddr, saddr" ... Steps to reproduce: Create some raw socket, connect it to an address, and cause some error situation: f.e. set ttl=1 where the remote address is more than 1 hop to reach. Set IPV6_RECVERR . Then send something and wait for the error (f.e. poll() with POLLERR|POLLIN). You should receive "time exceeded" icmp message (because of "ttl=1"), but the socket do not receive it. If you do not connect your raw socket, you will receive MSG_ERRQUEUE successfully. (The reason is that for unconnected socket there are no actual checks for local/remote addresses).

* [IPV6] MIP6: Loadable module support for MIPv6.Masahide NAKAMURA2007-07-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes MIPv6 loadable module named "mip6". Here is a modprobe.conf(5) example to load it automatically when user application uses XFRM state for MIPv6: alias xfrm-type-10-43 mip6 alias xfrm-type-10-60 mip6 Some MIPv6 feature is not included by this modular, however, it should not be affected to other features like either IPsec or IPv6 with and without the patch. We may discuss XFRM, MH (RAW socket) and ancillary data/sockopt separately for future work. Loadable features: * MH receiving check (to send ICMP error back) * RO header parsing and building (i.e. RH2 and HAO in DSTOPTS) * XFRM policy/state database handling for RO These are NOT covered as loadable: * Home Address flags and its rule on source address selection * XFRM sub policy (depends on its own kernel option) * XFRM functions to receive RO as IPv6 extension header * MH sending/receiving through raw socket if user application opens it (since raw socket allows to do so) * RH2 sending as ancillary data * RH2 operation with setsockopt(2) Signed-off-by: Masahide NAKAMURA <nakam@linux-ipv6.org> Signed-off-by: David S.

* [PATCH] remove many unneeded #includes of sched.hTim Schmielau2007-02-141-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).

* [IPV6]: Move nextheader offset to the IP6CBPatrick McHardy2006-01-071-2/+2
| | | | | | | | | | Move nextheader offset to the IP6CB to make it possible to pass a packet to ip6_input_finish multiple times and have it skip already parsed headers. As a nice side effect this gets rid of the manual hopopts skipping in ip6_input_finish. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>

* [NET]: Add const markers to various variables.Arjan van de Ven2005-11-291-1/+1
| | | | | | | | | | | the patch below marks various variables const in net/; the goal is to move them to the .rodata section so that they can't false-share cachelines with things that get written to, as well as potentially helping gcc a bit with optimisations. (these were found using a gcc patch to warn about such variables) Signed-off-by: Arjan van de Ven <arjan@infradead.org> Signed-off-by: David S. Miller <davem@davemloft.net>
