* [NET/IPV4/IPV6]: Change some sysctl variables to __read_mostlyBrian Haley2006-09-22
| | | | | | | | | | Change net/core, ipv4 and ipv6 sysctl variables to __read_mostly. Couldn't actually measure any performance increase while testing (.3% I consider noise), but seems like the right thing to do. Signed-off-by: Brian Haley <brian.haley@hp.com> Signed-off-by: David S.

* [NET]: Replace CHECKSUM_HW by CHECKSUM_PARTIAL/CHECKSUM_COMPLETEPatrick McHardy2006-09-22
| | | | | | | | | | | Replace CHECKSUM_HW by CHECKSUM_PARTIAL (for outgoing packets, whose checksum still needs to be completed) and CHECKSUM_COMPLETE (for incoming packets, device supplied full checksum).

* [IPV4]: Fix multiple bugs in IGMPv3David L Stevens2006-01-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1) 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 2) 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. 3) fix mca_crcount decrement to be after add_grec(), which needs its original value 4) add/remove delete records and prevent current advertisements when an exclude-mode filter moves from "active" to "inactive" or vice versa based on new filter additions. Items 1-3 are just IPv4 versions of the IPv6 bugs found by Yan Zheng and fixed earlier. Item #4 is a related bug that affects exclude-mode change records only (but not queries) and also occurs in IPv6 (IPv6 version coming soon).

* [IGMP]: workaround for IGMP v1/v2 bugDavid Stevens2005-12-02
| | | | | | | | | | | | | | | | | From: David Stevens <dlstevens@us.ibm.com> As explained at: http://www.cs.ucsb.edu/~krishna/igmp_dos/ With IGMP version 1 and 2 it is possible to inject a unicast report to a client which will make it ignore multicast reports sent later by the router. The fix is to only accept the report if is was sent to a multicast or unicast address. Signed-off-by: David S. Miller <davem@davemloft.net>
* [NET]: Detect hardware rx checksum faults correctlyHerbert Xu2005-11-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | Here is the patch that introduces the generic skb_checksum_complete which also checks for hardware RX checksum faults. If that happens, it'll call netdev_rx_csum_fault which currently prints out a stack trace with the device name. In future it can turn off RX checksum. I've converted every spot under net/ that does RX checksum checks to use skb_checksum_complete or __skb_checksum_complete with the exceptions of: * Those places where checksums are done bit by bit. These will call netdev_rx_csum_fault directly. * The following have not been completely checked/converted: ipmr ip_vs netfilter dccp This patch is based on patches and suggestions from Stephen Hemminger and David S. Miller. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
* [MCAST]: ip[6]_mc_add_src should be called when number of sources is zeroYan Zheng2005-11-02
| | | | | | | | | | | | | | | | | | And filter mode is exclude. Further explanation by David Stevens: Multicast source filters aren't widely used yet, and that's really the only feature that's affected if an application actually exercises this bug, as far as I can tell. An ordinary filter-less multicast join should still work, and only forwarded multicast traffic making use of filters and doing empty-source filters with the MSFILTER ioctl would be at risk of not getting multicast traffic forwarded to them because the reports generated would not be based on the correct counts.

* [IPV4]: Replace __in_dev_get with __in_dev_get_rcu/rtnlHerbert Xu2005-10-03
| | | | | | | | | | | | | | | | | | The following patch renames __in_dev_get() to __in_dev_get_rtnl() and introduces __in_dev_get_rcu() to cover the second case. 1) RCU with refcnt should use in_dev_get(). 2) RCU without refcnt should use __in_dev_get_rcu(). 3) All others must hold RTNL and use __in_dev_get_rtnl(). There is one exception in net/ipv4/route.c which is in fact a pre-existing race condition. I've marked it as such so that we remember to fix it.

* [IPV4]: fix IPv4 leave-group group matchingDavid L Stevens2005-07-08
| | | | | | | | | | | | This patch fixes the multicast group matching for IP_DROP_MEMBERSHIP, similar to the IP_ADD_MEMBERSHIP fix in a prior patch. Groups are identifiedby <group address,interface> and including the interface address in the match will fail if a leave-group is done by address when the join was done by index, or if different addresses on the same interface are used in the join and leave.

* [IPV4]: multicast API "join" issuesDavid L Stevens2005-07-08
| | | | | | | | | | | | | | | 1) Changes IP_ADD_SOURCE_MEMBERSHIP and MCAST_JOIN_SOURCE_GROUP to ignore EADDRINUSE errors on a "courtesy join" -- prior membership or not is ok for these. 2) Adds "leave group" equivalence of (INCLUDE, empty) filters in the delta-based API. Without this, mixing delta-based API calls that end in an (INCLUDE, empty) filter would not allow a subsequent regular IP_ADD_MEMBERSHIP. It also frees socket buffer memory that isn't needed for both the multicast group record and source filter. Signed-off-by: David L Stevens <dlstevens@us.ibm.com> Signed-off-by: David S.

* [IPV4]: multicast API "join" issuesDavid L Stevens2005-07-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch corrects a few problems with the IP_ADD_MEMBERSHIP socket option: 1) The existing code makes an attempt at reference counting joins when using the ip_mreqn/imr_ifindex interface. Joining the same group on the same socket is an error, whatever the API. This leads to unexpected results when mixing ip_mreqn by index with ip_mreqn by address, ip_mreq, or other API's. For example, ip_mreq followed by ip_mreqn of the same group will "work" while the same two reversed will not. Fixed to always return EADDRINUSE on a duplicate join and removed the (now unused) reference count in ip_mc_socklist. 2) The group-search list in ip_mc_join_group() is comparing a full ip_mreqn structure and all of it must match for it to find the group. This doesn't correctly match a group that was joined with ip_mreq or ip_mreqn with an address (with or without an index). It also doesn't match groups that are joined by different addresses on the same interface. All of these are the same multicast group, which is identified by group address and interface index. Fixed the check to correctly match groups so we don't get duplicate group entries on the ip_mc_socklist. 3) The old code allocates a multicast address before searching for duplicates requiring it to free in various error cases. This patch moves the allocate until after the search and igmp_max_memberships check, so never a need to allocate, then free an entry.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-16
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!
