From 59b2565cd91a67ced650739f36129650830211ac Mon Sep 17 00:00:00 2001 From: Dave Barach Date: Sun, 10 Sep 2017 15:04:27 -0400 Subject: Repair vlib API socket server - Teach vpp_api_test to send/receive API messages over sockets - Add memfd-based shared memory - Add api messages to create memfd-based shared memory segments - vpp_api_test supports both socket and shared memory segment connections - vpp_api_test pivot from socket to shared memory API messaging - add socket client support to libvlibclient.so - dead client reaper sends ping messages, container-friendly - dead client reaper falls back to kill (, 0) live checking if e.g. a python app goes silent for tens of seconds - handle ping messages in python client support code - teach show api ring about pairwise shared-memory segments - fix ip probing of already resolved destinations (VPP-998) We'll need this work to implement proper host-stack client isolation Change-Id: Ic23b65f75c854d0393d9a2e9d6b122a9551be769 Signed-off-by: Dave Barach Signed-off-by: Dave Wallace Signed-off-by: Florin Coras --- src/vlibapi/api_common.h | 9 +++++++++ 1 file changed, 9 insertions(+) (limited to 'src/vlibapi/api_common.h') diff --git a/src/vlibapi/api_common.h b/src/vlibapi/api_common.h index 8e6ab0ff094..324b260ecc6 100644 --- a/src/vlibapi/api_common.h +++ b/src/vlibapi/api_common.h @@ -50,14 +50,22 @@ typedef struct vl_api_registration_ u8 *name; /**< Client name */ + /* Zombie apocalypse checking */ + f64 last_heard; + int last_queue_head; + int unanswered_pings; + /** shared memory only: pointer to client input queue */ unix_shared_memory_queue_t *vl_input_queue; + svm_region_t *vlib_rp; + void *shmem_hdr; /* socket server and client */ u32 clib_file_index; /**< Socket only: file index */ i8 *unprocessed_input; /**< Socket only: pending input */ u32 unprocessed_msg_length; /**< Socket only: unprocssed length */ u8 *output_vector; /**< Socket only: output vecto */ + int *additional_fds_to_close; /* socket client only */ u32 server_handle; /**< Socket client only: server handle */ @@ -235,6 +243,7 @@ typedef struct svm_region_t *vlib_rp; /** Vector of all mapped shared-VM segments */ + svm_region_t **vlib_private_rps; svm_region_t **mapped_shmem_regions; /** Binary API shared-memory segment header pointer */ -- cgit 1.2.3-korg
