2020-09-14session: del app worker on socket detachFlorin Coras1-5/+11
Type: improvement Signed-off-by: Florin Coras <fcoras@cisco.com> Change-Id: Ic904abedcd270c95e782159170d457bc396424a0
2020-09-14session: add unix socket api for app attachmentFlorin Coras1-3/+504
This is an af_unix socket alternative to the binary api. To enable it, add use-app-socket-api under session stanza in startup.conf. When the socket api is enabled, attachments through the binary api are disabled. The socket api only works with memfd fifo segments, i.e., shm segments are not supported.

2020-05-04misc: binary api fuzz test fixesDave Barach1-2/+2
Add a hook to src/vlibapi/api_shared.c to fuzz (screw up) binary API messages, e.g. by xoring random data into them before processing. We specifically exempt client connection messages, and inband debug CLI messages. We step over msg_id, client index, client context, and sw_if_index. Otherwise, "make test" vectors fail too rapidly to learn anything. The goal is to reduce the number of crashes caused to zero. We're fairly close with this patch. Add vl_msg_api_max_length(void *mp), which returns the maximum plausible length for a binary API message. Use it to hardern vl_api_from_api_to_new_vec(...) which takes an additional argument - message pointer - so it can verify that astr->length is sane. If it's not sane, return a u8 *vector of the form "insane astr->length nnnn\0". Verify array lengths in vl_api_dhcp6_send_client_message_t_handler(...) and vl_api_dhcp6_pd_send_client_message_t_handler(...). Add a fairly effective binary API fuzz hook to the unittest plugin, and modify the "make test" framework.py to pass "api-fuzz { on|off }" to enable API fuzzing: "make API_FUZZ=on TEST=xxx test-debug" or similar Type: improvement Signed-off-by: Dave Barach <dave@barachs.net> Change-Id: I0157267652a163c01553d5267620f719cc6c3bde

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.

2019-08-27session: move ctrl messages from bapi to mqFlorin Coras1-26/+138
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.
