c5301899 - tipc: not enable tipc when ipv6 works as a module

Sun, 16 Aug 2020 09:32:03 +0000

tipc: not enable tipc when ipv6 works as a moduleWhen using ipv6_dev_find() in one module, it requires ipv6 not towork as a module. Otherwise, this error occurs in build: undefined reference to `ipv6_dev_find'.So fix it by adding "depends on IPV6 || IPV6=n" to tipc/Kconfig,as it does in sctp/Kconfig.Fixes: 5a6f6f579178 ("tipc: set ub->ifindex for local ipv6 address")Reported-by: kernel test robot Acked-by: Randy Dunlap Signed-off-by: Xin Long Signed-off-by: David S.

fc1b6d6d - tipc: introduce TIPC encryption & authentication

Fri, 08 Nov 2019 05:05:11 +0000

tipc: introduce TIPC encryption & authenticationThis commit offers an option to encrypt and authenticate all messaging,including the neighbor discovery messages. The currently most advancedalgorithm supported is the AEAD AES-GCM (like IPSec or TLS). Allencryption/decryption is done at the bearer layer, just before leavingor 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 allnodes 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 themessages 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 isalso used to print the crypto statistics at runtime:echo 0xfff1 > /proc/sys/net/tipc/max_tfmsThe patch defines a new TIPC version (v7) for the encryption message (-backward compatibility as well). The message is basically encapsulatedas 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 hardwarecrypto i.e. the Intel AES-NI CPU instructions, the throughput increasesupto ~85% for small messages and ~55% for large messages.By default, the new feature is inactive (i.e. no encryption) until usersets 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.MAINTAINERS | add two new files 'crypto.h' & 'crypto.c' in tipcAcked-by: Ying Xue Acked-by: Jon Maloy Signed-off-by: Tuong Lien Signed-off-by: David S.

c30b70de - tipc: implement socket diagnostics for AF_TIPC

tipc: implement socket diagnostics for AF_TIPCThis commit adds socket diagnostics capability for AF_TIPC in netlinkfamily 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 andavoid 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.Acked-by: Jon Maloy Acked-by: Ying Xue Signed-off-by: GhantaKrishnamurthy MohanKrishna Signed-off-by: Parthasarathy Bhuvaragan Signed-off-by: David S.

07f6c4bc - tipc: convert tipc reference table to use generic rhashtable

Wed, 07 Jan 2015 05:41:58 +0000

tipc: convert tipc reference table to use generic rhashtableAs tipc reference table is statically allocated, its memory sizerequested on stack initialization stage is quite big even if themaximum port number is just restricted to 8191 currently, however,the number already becomes insufficient in practice. But if themaximum ports is allowed to its theory value - 2^32, its consumedmemory size will reach a ridiculously unacceptable value. Apart fromthis, heavy tipc users spend a considerable amount of time intipc_sk_get() due to the read-lock on ref_table_lock.If tipc reference table is converted with generic rhashtable, abovementioned both disadvantages would be resolved respectively: makinguse of the new resizable hash table can avoid locking on the lookup;smaller memory size is required at initial stage, for example, 256hash bucket slots are requested at the beginning phase instead ofallocating the entire 8191 slots in old mode. The hash table willgrow if entries exceeds 75% of table size up to a total table sizeof 1M, and it will automatically shrink if usage falls below 30%,but the minimum table size is allowed down to 256.Also converts ref_table_lock to a separate mutex to protect hash tablemutations on write side. Lastly defers the release of the socketreference using call_rcu() to allow using an RCU read-side protectedcall to rhashtable_lookup().Signed-off-by: Ying Xue Acked-by: Jon Maloy Acked-by: Erik Hugne Cc: Thomas Graf Acked-by: Thomas Graf Signed-off-by: David S.
