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. This allows the array entry used by the disabled bearer to be re-used if the same bearer (or a different one) is subsequently enabled.

Change TIPC's shutdown code to deactivate generic networking support before terminating Ethernet media support. The deactivation of generic networking support causes all existing bearers to be destroyed, meaning the Ethernet media termination routine no longer has to bother marking them as unavailable.

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. Thanks to Florian Westphal <fw@strlen.de> for his contributions to the development of this enhancement.

Adds a check to ensure that TIPC ignores an incoming neighbor discovery message that specifies an invalid media address as its source. The check ensures that the source address is a valid, non-broadcast address that could legally be used by a neighboring link endpoint.

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.

Enhances TIPC's Ethernet media support to provide 3 new address conversion routines, which allow TIPC to interpret an address that is in string form and to convert an address to and from the 20 byte format used in TIPC's neighbor discovery messages. These routines are pre-requisites to a follow on commit that hides all media-specific addressing details from TIPC's generic bearer code.

Enhances conversion of a media address to printable form so that an unconvertable address will be displayed as a string of hex digits, rather than not being displayed at all.

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.

"! --connbytes 23:42" should match if the packet/byte count is not in range. As there is no explict "invert match" toggle in the match structure, userspace swaps the from and to arguments (i.e., as if "--connbytes 42:23" were given). However, "what <= 23 && what >= 42" will always be false. Change things so we use "||" in case "from" is larger than "to". This change may look like it breaks backwards compatibility when "to" is 0. However, older iptables binaries will refuse "connbytes 42:0", and current releases treat it to mean "! --connbytes 0:42", so we should be fine.
