2010-08-05DNS: Separate out CIFS DNS Resolver codeWang Lei
Separate out the DNS resolver key type from the CIFS filesystem into its own module so that it can be made available for general use, including the AFS filesystem module. This facility makes it possible for the kernel to upcall to userspace to have it issue DNS requests, package up the replies and present them to the kernel in a useful form. The kernel is then able to cache the DNS replies as keys can be retained in keyrings. Resolver keys are of type "dns_resolver" and have a case-insensitive description that is of the form "[<type>:]<domain_name>". The optional <type> indicates the particular DNS lookup and packaging that's required. The <domain_name> is the query to be made. If <type> isn't given, a basic hostname to IP address lookup is made, and the result is stored in the key in the form of a printable string consisting of a comma-separated list of IPv4 and IPv6 addresses. This key type is supported by userspace helpers driven from /sbin/request-key and configured through /etc/request-key.conf. The cifs.upcall utility is invoked for UNC path server name to IP address resolution. The CIFS functionality is encapsulated by the dns_resolve_unc_to_ip() function, which is used to resolve a UNC path to an IP address for CIFS filesystem. This part remains in the CIFS module for now. See the added Documentation/networking/dns_resolver.txt for more information.

Below you will find an updated version from the original series bunching all patches into one big patch updating broken web addresses that are located in Documentation/* Some of the addresses date as far far back as 1995 etc... so searching became a bit difficult, the best way to deal with these is to use web.archive.org to locate these addresses that are outdated. Now there are also some addresses pointing to .spec files some are located, but some(after searching on the companies site)where still no where to be found.

2010-06-05bonding: allow user-controlled output slave selectionAndy Gospodarek
v2: changed bonding module version, modified to apply on top of changes from previous patch in series, and updated documentation to elaborate on multiqueue awareness that now exists in bonding driver. This patch give the user the ability to control the output slave for round-robin and active-backup bonding. Similar functionality was discussed in the past, but Jay Vosburgh indicated he would rather see a feature like this added to existing modes rather than creating a completely new mode. Jay's thoughts as well as Neil's input surrounding some of the issues with the first implementation pushed us toward a design that relied on the queue_mapping rather than skb marks. Round-robin and active-backup modes were chosen as the first users of this slave selection as they seemed like the most logical choices when considering a multi-switch environment. Round-robin mode works without any modification, but active-backup does require inclusion of the first patch in this series and setting the 'all_slaves_active' flag. This will allow reception of unicast traffic on any of the backup interfaces. This was tested with IPv4-based filters as well as VLAN-based filters with good results. More information as well as a configuration example is available in the patch to Documentation/networking/bonding.txt.

2010-06-02packet_mmap: expose hw packet timestamps to network packet capture utilitiesScott McMillan
This patch adds a setting, PACKET_TIMESTAMP, to specify the packet timestamp source that is exported to capture utilities like tcpdump by packet_mmap. PACKET_TIMESTAMP accepts the same integer bit field as SO_TIMESTAMPING. However, only the SOF_TIMESTAMPING_SYS_HARDWARE and SOF_TIMESTAMPING_RAW_HARDWARE values are currently recognized by PACKET_TIMESTAMP. SOF_TIMESTAMPING_SYS_HARDWARE takes precedence over SOF_TIMESTAMPING_RAW_HARDWARE if both bits are set. If PACKET_TIMESTAMP is not set, a software timestamp generated inside the networking stack is used (the behavior before this setting was added).

2010-03-02USB: cxacru: remove cxacru-cf.bin loaderSimon Arlott
This has never worked properly because wsize passed to cxacru_cm() is incorrectly set to the number of values instead of the data bytes. The maximum number of values that can be set at once is 7 which means the device will not get enough data to work with and none of the configuration values will be used. At least one existing cxacru-cf.bin file contains invalid data which will prevent the modem from syncing properly. Fixing it is likely to break existing systems, and the new sysfs interface for setting configuration parameters can provide the same functionality.

2010-02-12dccp: allow probing of CCID-array lengthGerrit Renker
This fixes a problem in the DCCP getsockopt() API: currently there is no way for a user to a priori know the number of built-in CCIDs, other than trying DCCP_SOCKOPT_AVAILABLE_CCIDS in a loop, incrementing the option length until EINVAL is no longer returned. This patch truncates the array to the user-provided length. No copy is made when the length is <= 0. Due to the length restriction in do_dccp_getsockopt() to sizeof(int), the minimum array length remains 4, which is a reasonable default (only 3 CCIDs, CCID-2..4, are currently defined).

This is to be used together with switch technologies, like RFC3069, that where the individual ports are not allowed to communicate with each other, but they are allowed to talk to the upstream router. As described in RFC 3069, it is possible to allow these hosts to communicate through the upstream router by proxy_arp'ing. This patch basically allow proxy arp replies back to the same interface (from which the ARP request/solicitation was received). Tunable per device via proc "proxy_arp_pvlan": /proc/sys/net/ipv4/conf/*/proxy_arp_pvlan This switch technology is known by different vendor names: - In RFC 3069 it is called VLAN Aggregation. - Cisco and Allied Telesyn call it Private VLAN. - Hewlett-Packard call it Source-Port filtering or port-isolation. - Ericsson call it MAC-Forced Forwarding (RFC Draft).

Ah, I knew I forgot something :) Here is v4. tavi >From 24d96d825b9fa832b22878cc6c990d5711968734 Mon Sep 17 00:00:00 2001 From: Octavian Purdila <opurdila@ixiacom.com> Date: Fri, 2 Oct 2009 00:51:15 +0300 Subject: [PATCH] ipv6: new sysctl for sending TLLAO with unicast NAs Neighbor advertisements responding to unicast neighbor solicitations did not include the target link-layer address option. This patch adds a new sysctl option (disabled by default) which controls whether this option should be sent even with unicast NAs. The need for this arose because certain routers expect the TLLAO in some situations even as a response to unicast NS packets. Moreover, RFC 2461 recommends sending this to avoid a race condition (section 4.4, Target link-layer address) Signed-off-by: Cosmin Ratiu <cratiu@ixiacom.com> Signed-off-by: Octavian Purdila <opurdila@ixiacom.com> Signed-off-by: David S.

2009-10-07bonding: introduce primary_reselect optionJiri Pirko
In some cases there is not desirable to switch back to primary interface when it's link recovers and rather stay with currently active one. We need to avoid packetloss as much as we can in some cases. This is solved by introducing primary_reselect option. Note that enslaved primary slave is set as current active no matter what. Patch modified by Jay Vosburgh as follows: fixed bug in action after change of option setting via sysfs, revised the documentation update, and bumped the bonding version number.

2009-10-04pktgen: Fix multiqueue handlingEric Dumazet
It is not currently possible to instruct pktgen to use one selected tx queue. When Robert added multiqueue support in commit 45b270f8, he added an interval (queue_map_min, queue_map_max), and his code doesnt take into account the case of min = max, to select one tx queue exactly. I suspect a high performance setup on a eight txqueue device wants to use exactly eight cpus, and assign one tx queue to each sender. This patchs makes pktgen select the right tx queue, not the first one. Also updates Documentation to reflect Robert changes.
