2008-01-25IPoIB: improve IPv4/IPv6 to IB mcast mapping functionsRolf Manderscheid
An IPoIB subnet on an IB fabric that spans multiple IB subnets can't use link-local scope in multicast GIDs. The existing routines that map IP/IPv6 multicast addresses into IB link-level addresses hard-code the scope to link-local, and they also leave the partition key field uninitialised. This patch adds a parameter (the link-level broadcast address) to the mapping routines, allowing them to initialise both the scope and the P_Key appropriately, and fixes up the call sites. The next step will be to add a way to configure the scope for an IPoIB interface. Signed-off-by: Rolf Manderscheid <rvm@obsidianresearch.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2007-10-10[IPV6]: Add ICMPMsgStats MIB (RFC 4293) [rev 2]David L Stevens
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.

2006-03-20[IPV6]: ADDRCONF: Use our standard algorithm for randomized ifid.YOSHIFUJI Hideaki
RFC 3041 describes an algorithm to generate random interface identifier. In RFC 3041bis, it is allowed to use different algorithm than one described in RFC 3041. So, let's use our standard pseudo random algorithm to simplify our implementation. Signed-off-by: YOSHIFUJI Hideaki <yoshfuji@linux-ipv6.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2005-12-27[IPV6] mcast: Fix multiple issues in MLDv2 reports.David L Stevens
The below "jumbo" patch fixes the following problems in MLDv2. 1) Add necessary "ntohs" to recent "pskb_may_pull" check [breaks all nonzero source queries on little-endian (!)] 2) Add locking to source filter list [resend of prior patch] 3) fix "mld_marksources()" to a) send nothing when all queried sources are excluded b) send full exclude report when source queried sources are not excluded c) don't schedule a timer when there's nothing to report NOTE: RFC 3810 specifies the source list should be saved and each source reported individually as an IS_IN. This is an obvious DOS path, requiring the host to store and then multicast as many sources as are queried (e.g., millions...). This alternative sends a full, relevant report that's limited to number of sources present on the machine. 4) fix "add_grec()" to send empty-source records when it should The original check doesn't account for a non-empty source list with all sources inactive; the new code keeps that short-circuit case, and also generates the group header with an empty list if needed. 5) fix mca_crcount decrement to be after add_grec(), which needs its original value These issues (other than item #1 ;-) ) were all found by Yan Zheng, much thanks!

2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
