Adds code to release any unsent broadcast messages in the broadcast link transmit queue if TIPC loses contact with its only neighboring node. Previously, a broadcast link that was in the congested state would hold on to the unsent messages, even though the messages were now undeliverable.

The two broadcast link statistics fields that are used to derive the average length of that link's transmit queue are now updated only after a successful attempt to send a broadcast message, since there is no need to update these values when an unsuccessful send attempt leaves the queue unchanged.

Adds a check to detect when an attempt is made to send a message via the broadcast link and no neighboring nodes are currently available to receive it. Rather than wasting effort passing the message to the broadcast link and broadcast bearer, who will only throw it away, TIPC now frees the message immediately and reports success (i.e. the message has been delivered to all available destinations).

Fixes oversight that allowed broadcast link node map to be updated without first taking the broadcast link spinlock that protects the map. As part of this fix the node map has been incorporated into the broadcast link structure to make the need for such protection more evident.

Creates global variables to hold the broadcast link's pseudo-bearer and pseudo-link structures, rather than allocating them dynamically. There is only a single instance of each structure, and changing over to static allocation allows elimination of code to handle the cases where dynamic allocation was unsuccessful. The memset in the teardown code may look like they aren't used, but the same teardown code is run when there is a non-fatal error at init-time, so that stale data isn't present when the user fixes the cause of the soft error.

Gets rid of two pointless operations that zero out the array used to record information about TIPC's Ethernet bearers. There is no need to initialize the array on start up since it is a global variable that is already zero'd out, and there is no need to zero it out on exit because the array is never referenced again.

Modifies Ethernet bearer disable logic to break the association between the bearer and its device driver at the time the bearer is disabled, rather than when the TIPC module is unloaded.

Permits run-time alteration of default link settings on a per-media and per-bearer basis, in addition to the existing per-link basis. The following syntax can now be used: tipc-config -lt=<link-name|bearer-name|media-name>/<tolerance> tipc-config -lp=<link-name|bearer-name|media-name>/<priority> tipc-config -lw=<link-name|bearer-name|media-name>/<window> Note that changes to the default settings for a given media type has no effect on the default settings used by existing bearers. Similarly, changes to default bearer settings has no effect on existing link endpoints that utilize that interface.

Reworks TIPC's media address data structure and associated processing routines to transfer all media-specific details of address conversion to the associated TIPC media adaptation code. TIPC's generic bearer code now only needs to know which media type an address is associated with and whether or not it is a broadcast address, and totally ignores the "value" field that contains the actual media-specific addressing info. These changes eliminate the need for a number of endianness conversion operations and will make it easier for TIPC to support new media types in the future.

Simplifies error handling performed during media registration, since TIPC no longer supports the dynamic addition of new media types that are potentially error-prone. These simplifications include the following: 1) No longer check for premature registration of a new media type. 2) No longer check for negative link priority values (which was pointless since such values are unsigned, and could cause a compiler warning). 3) No longer generate a warning describing the exact cause of any registration failure (just warns that overall registration failed).

We currently have two ways to account traffic in netfilter: - iptables chain and rule counters: # iptables -L -n -v Chain INPUT (policy DROP 3 packets, 867 bytes) pkts bytes target prot opt in out source destination 8 1104 ACCEPT all -- lo * 0.0.0.0/0 0.0.0.0/0 - use flow-based accounting provided by ctnetlink: # conntrack -L tcp 6 431999 ESTABLISHED src=192.168.1.130 dst=212.106.219.168 sport=58152 dport=80 packets=47 bytes=7654 src=212.106.219.168 dst=192.168.1.130 sport=80 dport=58152 packets=49 bytes=66340 [ASSURED] mark=0 use=1 While trying to display real-time accounting statistics, we require to pool the kernel periodically to obtain this information. This is OK if the number of flows is relatively low. However, in case that the number of flows is huge, we can spend a considerable amount of cycles to iterate over the list of flows that have been obtained. Moreover, if we want to obtain the sum of the flow accounting results that match some criteria, we have to iterate over the whole list of existing flows, look for matchings and update the counters. This patch adds the extended accounting infrastructure for nfnetlink which aims to allow displaying real-time traffic accounting without the need of complicated and resource-consuming implementation in user-space. Basically, this new infrastructure allows you to create accounting objects. One accounting object is composed of packet and byte counters. In order to manipulate create accounting objects, you require the new libnetfilter_acct library. It contains several examples of use: libnetfilter_acct/examples# ./nfacct-add http-traffic libnetfilter_acct/examples# ./nfacct-get http-traffic = { pkts = 000000000000, bytes = 000000000000 }; Then, you can use one of this accounting objects in several iptables rules using the new nfacct match (which comes in a follow-up patch): # iptables -I INPUT -p tcp --sport 80 -m nfacct --nfacct-name http-traffic # iptables -I OUTPUT -p tcp --dport 80 -m nfacct --nfacct-name http-traffic The idea is simple: if one packet matches the rule, the nfacct match updates the counters.
