2019-10-30tls: fix on tcp connection resetZeyu Zhang1-1/+2
VPP would fail in tcp_connection_reset() if the tls or app session was just created. Type: fix Change-Id: I45d107f57e4f3fc468c15ca3392d5e1c413bd690 Signed-off-by: Zeyu Zhang <zeyu.zhang@intel.com>

2019-10-17session tcp: infra for transports to send buffersFlorin Coras2-0/+29
Type: feature Add infra that allows transpors to enqueue pending buffers without the need to build and manage their own pending frames. An important benefit is the fact that buffer wire/tx ordering is ensured by session layer. Change-Id: I764fd1693d610b321a1d0c84b648a314f14583db Signed-off-by: Florin Coras <fcoras@cisco.com>

Type: feature This changes the behavior of both API calls APPLICATION_TLS_CERT_ADD & APPLICATION_TLS_KEY_ADD certificates and keys aren't bound to an app, they are passed to it via connect / listen using the message queue. This should be followed by a per protocol (QUIC/TLS) crypto_context store to save devrived structs Change-Id: I36873bc8b63b5c72776c69e8cd9febc9cae31882 Signed-off-by: Nathan Skrzypczak <nathan.skrzypczak@gmail.com>

For instance show session thread 1 proto tcp state ready range 0 20 verbose Shows the session ids for the first 20 tcp sessions in thread 1 that are in ready state. To avoid excessive output that could reasult in the worker barrier being held by the main thread for long periods of time, the session cli will only output: - session ids (verbose == 1) for a maximum of 50 sessions / worker - verbose > 1 details for a maximum of 10 sessions Change-Id: I2cfb351b548e2e0a1d5b4345810be613e2917d17 Signed-off-by: Florin Coras <fcoras@cisco.com>

2019-09-03api: enforce vla is last and fixed string typeOle Troan1-1/+1
Enforce that variable length fields are the last element of API messages. Add a 'fixed' version of string type, since dealing with multiple variable length strings turned out too painful for the C language bindings. The string type is now: { string name[64]; // NUL terminated C-string. Essentially decays to u8 name[64] string name[]; // Variable length string with embedded len field (vl_api_string_t) }; The latter notation could be made available to other types as well. e.g. { vl_api_address_t addresses[]; } instead of { u32 n_addr; vl_api_address_t addresses[n_addr]; }; Type: fix Change-Id: I18fa17ef47227633752ab50453e8d20a652a9f9b Signed-off-by: Ole Troan <ot@cisco.com>

2019-08-27session: move ctrl messages from bapi to mqFlorin Coras9-106/+675
Type:refactor Moves connect, disconnect, bind, unbind and app detach to message queue from binary api. Simplifies app/vcl interaction with the session layer since all session control messages are now handled over the mq. Add/del segment messages require internal C api changes which affect all builtin applications. They'll be moved in a different patch and might not be back portable to 19.08.

2019-08-09session: allow closed transports to sendFlorin Coras1-4/+16
Type:fix Transports like tcp may notify session layer of a close but they may defer the connection's deletion (e.g., tcp time-wait). During that time, transports may still want to send packets. So, unless the session has no transport (transport-deleted state), allow the transport to send. Change-Id: I3ae335c7b951ff64be8529a5e3f3ad790feddc84 Signed-off-by: Florin Coras <fcoras@cisco.com>

2019-08-01vppinfra: refactor clib_rwlock_t to use single condition variablejaszha031-1/+0
Previous implementation of clib_rwlock_t used two spinlocks: one writer lock, and one to guard the counter for the number of readers. This implementation uses a single condition variable rw_cnt which has the following properties: if a writer has the rwlock, rw_cnt = -1 if the rwlock is free, rw_cnt = 0 otherwise, rw_cnt > 0 and rw_cnt = number of readers rw_cnt will never be less than -1 Benchmarking: The results below are the cycle counts from test_rwlock.c, configured so that for 10000 iterations, 6 reader and 6 writer threads on separate cores are spawned such that each writer thread increments a global counter 10000 times in each iteration. For Taishan, 4 reader and 4 writer threads are spawned in each test. x86 Xeon old rwlock: 12.473e8, 11.655e8, 13.201e8, 11.347e8, 13.182e8 x86 Xeon new rwlock: 5.881e8, 5.796e8, 6.536e8, 5.540e8, 5.890e8 Aarch64 ThX2* old rwlock: 9.263e7, 8.933e7, 9.074e7, 8.979e7, 9.378e7 Aarch64 ThX2* new rwlock: 7.221e7, 8.107e7, 7.515e7, 7.672e7, 7.386e7 A72 old rwlock: 3.268e6, 3.200e6, 3.086e6, 3.176e6, 3.170e6 A72 new rwlock: 1.261e6, 1.288e6, 1.251e6, 1.229e6, 1.234e6 *ThunderX2 used additional gcc options "-march=armv8.1-a+crc+crypto+lse" Type: refactor Change-Id: I7c347d3037b36205ab532cbcb52a374c846eb275 Signed-off-by: Jason Zhang <jason.zhang2@arm.com> Reviewed-by: Honnappa Nagarahalli <honnappa.nagarahalli@arm.com> Reviewed-by: Lijian Zhang <Lijian.Zhang@arm.com>
