Jon Maloy says: ==================== tipc: introduce 128-bit auto-configurable node id We introduce a 128-bit free-format node identity as an alternative to the legacy <Zone.Cluster.Node> structured 32-bit node address. We also make configuration of this identity optional; if a bearer is enabled without a pre-configured node id it will be set automatically based on the used interface's MAC or IP address. ==================== Signed-off-by: -
Jon Maloy authored
Selecting and explicitly configuring a TIPC node identity may be unwanted in some cases. In this commit we introduce a default setting if the identity has not been set at the moment the first bearer is enabled. We do this by using a raw copy of a unique identifier from the used interface: MAC address in the case of an L2 bearer, IPv4/IPv6 address in the case of a UDP bearer. Acked-by:

When a 32-bit node address is generated from a 128-bit identifier, there is a risk of collisions which must be discovered and handled. We do this as follows: - We don't apply the generated address immediately to the node, but do instead initiate a 1 sec trial period to allow other cluster members to discover and handle such collisions. - During the trial period the node periodically sends out a new type of message, DSC_TRIAL_MSG, using broadcast or emulated broadcast, to all the other nodes in the cluster. - When a node is receiving such a message, it must check that the presented 32-bit identifier either is unused, or was used by the very same peer in a previous session. In both cases it accepts the request by not responding to it. - If it finds that the same node has been up before using a different address, it responds with a DSC_TRIAL_FAIL_MSG containing that address. - If it finds that the address has already been taken by some other node, it generates a new, unused address and returns it to the requester. - During the trial period the requesting node must always be prepared to accept a failure message, i.e., a message where a peer suggests a different (or equal) address to the one tried. In those cases it must apply the suggested value as trial address and restart the trial period. This algorithm ensures that in the vast majority of cases a node will have the same address before and after a reboot. If a legacy user configures the address explicitly, there will be no trial period and messages, so this protocol addition is completely backwards compatible. Acked-by:

We add a 128-bit node identity, as an alternative to the currently used 32-bit node address. For the sake of compatibility and to minimize message header changes we retain the existing 32-bit address field. When not set explicitly by the user, this field will be filled with a hash value generated from the much longer node identity, and be used as a shorthand value for the latter. We permit either the address or the identity to be set by configuration, but not both, so when the address value is set by a legacy user the corresponding 128-bit node identity is generated based on the that value.

As a preparation to changing the addressing structure of TIPC we replace all direct accesses to the tipc_net::own_addr field with the function dedicated for this, tipc_own_addr(). There are no changes to program logics in this commit. Acked-by:

Jon Maloy authored
The removal of an internal structure of the node address has an unwanted side effect. - Currently, if a user is sending an anycast message with destination domain 0, the tipc_namebl_translate() function will use the 'closest- first' algorithm to first look for a node local destination, and only when no such is found, will it resort to the cluster global 'round- robin' lookup algorithm. - Current users can get around this, and enforce unconditional use of global round-robin by indicating a destination as Z.0.0 or Z.C.0. - This option disappears when we make the node address flat, since the lookup algorithm has no way of recognizing this case. So, as long as there are node local destinations, the algorithm will always select one of those, and there is nothing the sender can do to change this. We solve this by eliminating the 'closest-first' option, which was never a good idea anyway, for non-legacy users, but only for those. To distinguish between legacy users and non-legacy users we introduce a new flag 'legacy_addr_format' in struct tipc_core, to be set when the user configures a legacy-style Z.C.N node address. Hence, when a legacy user indicates a zero lookup domain 'closest-first' is selected, and in all other cases we use 'round-robin'. Acked-by:

Nominally, TIPC organizes network nodes into a three-level network hierarchy consisting of the levels 'zone', 'cluster' and 'node'. This hierarchy is reflected in the node address format, - it is sub-divided into an 8-bit zone id, and 12 bit cluster id, and a 12-bit node id. However, the 'zone' and 'cluster' levels have in reality never been fully implemented,and never will be. The result of this has been that the first 20 bits the node identity structure have been wasted, and the usable node identity range within a cluster has been limited to 12 bits. This is starting to become a problem. In the following commits, we will need to be able to connect between nodes which are using the whole 32-bit value space of the node address. We therefore remove the restrictions on which values can be assigned to node identity, -it is from now on only a 32-bit integer with no assumed internal structure. Isolation between clusters is now achieved only by setting different values for the 'network id' field used during neighbor discovery, in practice leading to the latter becoming the new cluster identity. The rules for accepting discovery requests/responses from neighboring nodes now become: - If the user is using legacy address format on both peers, reception of discovery messages is subject to the legacy lookup domain check in addition to the cluster id check. - Otherwise, the discovery request/response is always accepted, provided both peers have the same network id. This secures backwards compatibility for users who have been using zone or cluster identities as cluster separators, instead of the intended 'network id'. Acked-by:

To facilitate the coming changes in the neighbor discovery functionality we make some renaming and refactoring of that code. The functional changes in this commit are trivial, e.g., that we move the message sending call in tipc_disc_timeout() outside the spinlock protected region. Acked-by:

Dave Watson says: ==================== TLS Rx TLS tcp socket RX implementation, to match existing TX code. This patchset completes the software TLS socket, allowing full bi-directional communication over TLS using normal socket syscalls, after the handshake has been done in userspace. Only the symmetric encryption is done in the kernel. This allows usage of TLS sockets from within the kernel (for example with network block device, or from bpf). Performance can be better than userspace, with appropriate crypto routines [1]. sk->sk_socket->ops must be overridden to implement splice_read and poll, but otherwise the interface & implementation match TX closely. strparser is used to parse TLS framing on receive. There are Openssl RX patches that work with this interface [2], as well as a testing tool using the socket interface directly (without cmsg support) [3]. An example tcp socket setup is: // Normal tcp socket connect/accept, and TLS handshake // using any TLS library. setsockopt(sock, SOL_TCP, TCP_ULP, "tls", sizeof("tls")); struct tls12_crypto_info_aes_gcm_128 crypto_info_rx; // Fill in crypto_info based on negotiated keys. setsockopt(sock, SOL_TLS, TLS_RX, &crypto_info, sizeof(crypto_info_rx)); // You can optionally TLX_TX as well. char buffer[16384]; int ret = recv(sock, buffer, 16384); // cmsg can be received using recvmsg and a msg_control // of type TLS_GET_RECORD_TYPE will be set. V1 -> V2 * For too-small framing errors, return EBADMSG, to match openssl error code semantics. Docs and commit logs about this also updated. RFC -> V1 * Refactor 'tx' variable names to drop tx * Error return codes changed per discussion * Only call skb_cow_data based on in-place decryption, drop unnecessary frag list check.

Add rx path for tls software implementation. recvmsg, splice_read, and poll implemented. An additional sockopt TLS_RX is added, with the same interface as TLS_TX. Either TLX_RX or TLX_TX may be provided separately, or together (with two different setsockopt calls with appropriate keys). Control messages are passed via CMSG in a similar way to transmit. If no cmsg buffer is passed, then only application data records will be passed to userspace, and EIO is returned for other types of alerts. EBADMSG is passed for decryption errors, and EMSGSIZE is passed for framing too big, and EBADMSG for framing too small (matching openssl semantics). EINVAL is returned for TLS versions that do not match the original setsockopt call. All are unrecoverable. strparser is used to parse TLS framing. Decryption is done directly in to userspace buffers if they are large enough to support it, otherwise sk_cow_data is called (similar to ipsec), and buffers are decrypted in place and copied. splice_read always decrypts in place, since no buffers are provided to decrypt in to. sk_poll is overridden, and only returns POLLIN if a full TLS message is received. Otherwise we wait for strparser to finish reading a full frame. Actual decryption is only done during recvmsg or splice_read calls. Signed-off-by:
