The Transparent Inter Process Communication (TIPC) protocol is
specially designed for intra cluster communication. This protocol
originates from Ericsson where it has been used in carrier grade
cluster applications for many years.
tipc: Clean up configuration file This patch addresses a number of minor (mostly cosmetic) issues relating to the configuration of TIPC, including the following: - Corrects range limits for maximum number of ports per node - Adds missing range limits for size of log buffer - Removes configuration setting relating to unsupported slave node capability - Standardizes description and help text wording for configuration settings - Removes unneeded blank spaces Signed-off-by: Allan Stephens <allan.stephens@windriver.com> Signed-off-by: David S.

This protocol support is also available as a module ( = code which
can be inserted in and removed from the running kernel whenever you
want). The module will be called tipc. If you want to compile it
docs: kbuild: convert docs to ReST and rename to *.rst The kbuild documentation clearly shows that the documents there are written at different times: some use markdown, some use their own peculiar logic to split sections. Convert everything to ReST without affecting too much the author's style and avoiding adding uneeded markups. The conversion is actually: - add blank lines and identation in order to identify paragraphs; - fix tables markups; - add some lists markups; - mark literal blocks; - adjust title markups. At its new index.rst, let's add a :orphan: while this is not linked to the main index.rst file, in order to avoid build warnings.

tipc: add InfiniBand media type Add InfiniBand media type based on the ethernet media type. The only real difference is that in case of InfiniBand, we need the entire 20 bytes of space reserved for media addresses, so the TIPC media type ID is not explicitly stored in the packet payload.

tipc: add ip/udp media type The ip/udp bearer can be configured in a point-to-point mode by specifying both local and remote ip/hostname, or it can be enabled in multicast mode, where links are established to all tipc nodes that have joined the same multicast group. The multicast IP address is generated based on the TIPC network ID, but can be overridden by using another multicast address as remote ip.

tipc: introduce TIPC encryption & authentication This commit offers an option to encrypt and authenticate all messaging, including the neighbor discovery messages. The currently most advanced algorithm supported is the AEAD AES-GCM (like IPSec or TLS). All encryption/decryption is done at the bearer layer, just before leaving or after entering TIPC. Supported features: - Encryption & authentication of all TIPC messages (header + data); - Two symmetric-key modes: Cluster and Per-node; - Automatic key switching; - Key-expired revoking (sequence number wrapped); - Lock-free encryption/decryption (RCU); - Asynchronous crypto, Intel AES-NI supported; - Multiple cipher transforms; - Logs & statistics; Two key modes: - Cluster key mode: One single key is used for both TX & RX in all nodes in the cluster. - Per-node key mode: Each nodes in the cluster has one specific TX key. For RX, a node requires its peers' TX key to be able to decrypt the messages from those peers. Key setting from user-space is performed via netlink by a user program (e.g. the iproute2 'tipc' tool). Internal key state machine: Attach Align(RX) +-+ +-+ | V | V +---------+ Attach +---------+ | IDLE |---------------->| PENDING |(user = 0) +---------+ +---------+ A A Switch| A | | | | | | Free(switch/revoked) | | (Free)| +----------------------+ | |Timeout | (TX) | | |(RX) | | | | | | v | +---------+ Switch +---------+ | PASSIVE |<----------------| ACTIVE | +---------+ (RX) +---------+ (user = 1) (user >= 1) The number of TFMs is 10 by default and can be changed via the procfs 'net/tipc/max_tfms'. At this moment, as for simplicity, this file is also used to print the crypto statistics at runtime: echo 0xfff1 > /proc/sys/net/tipc/max_tfms The patch defines a new TIPC version (v7) for the encryption message (- backward compatibility as well). The message is basically encapsulated as follows: +----------------------------------------------------------+ | TIPCv7 encryption | Original TIPCv2 | Authentication | | header | packet (encrypted) | Tag | +----------------------------------------------------------+ The throughput is about ~40% for small messages (compared with non- encryption) and ~9% for large messages. With the support from hardware crypto i.e. the Intel AES-NI CPU instructions, the throughput increases upto ~85% for small messages and ~55% for large messages. By default, the new feature is inactive (i.e. no encryption) until user sets a key for TIPC. There is however also a new option - "TIPC_CRYPTO" in the kernel configuration to enable/disable the new code when needed.

tipc: implement socket diagnostics for AF_TIPC This commit adds socket diagnostics capability for AF_TIPC in netlink family NETLINK_SOCK_DIAG in a new kernel module (diag.ko). The following are key design considerations: - config TIPC_DIAG has default y, like INET_DIAG. - only requests with flag NLM_F_DUMP is supported (dump all). - tipc_sock_diag_req message is introduced to send filter parameters. - the response attributes are of TLV, some nested. To avoid exposing data structures between diag and tipc modules and avoid code duplication, the following additions are required: - export tipc_nl_sk_walk function to reuse socket iterator. - export tipc_sk_fill_sock_diag to fill the tipc diag attributes. - create a sock_diag response message in __tipc_add_sock_diag defined in diag.c and use the above exported tipc_sk_fill_sock_diag to fill response.
