2021-12-16api: Fix reaper functions for socket clientsNeale Ranns1-1/+2
Type: fix The pub_sub_handler() stores registrations key'd with the message's client_index (which is in network-order). The socket-client invokes the reaper function (to cleanup these registrations) using the pool index of the registration. hence the pub-sub registration is not removed. change the socket-client to pass the network-order client_index. This approach was chosen in preference to chaning the way the registrations are key'd since the memory-client also uses this registration, and correclty passes the client_index to the reaper.

2021-12-14api: verify message size on receiptKlement Sekera4-31/+58
When a message is received, verify that it's sufficiently large to accomodate any VLAs within message. To do that, we need a way to calculate message size including any VLAs. This patch adds such funcionality to vppapigen and necessary C code to use those to validate message size on receipt. Drop messages which are malformed.

2021-03-19api: Avoid the usage of the freed registration by the API callsAndrew Yourtchenko1-23/+51
This issue happens if: - the API client connects via Unix socket - the client issues the *_dump API call and immediately disconnects What happens after is that the API handler keeps sending the *_details messages, however at some point the write fails, and the socket is deleted. The attempt of a use of the registration pointer results in interpreting the socket as a shared memory socket. This results in a crash, because the data in this structure then does not make sense, like the below: | |Thread 1 "vpp_main" received signal SIGSEGV, Segmentation fault. |__GI___pthread_mutex_lock (mutex=0x0) at ../nptl/pthread_mutex_lock.c:67 |67 ../nptl/pthread_mutex_lock.c: No such file or directory. |(gdb) bt |#0 __GI___pthread_mutex_lock (mutex=0x0) at ../nptl/pthread_mutex_lock.c:67 |#1 0x00007ffff500f957 in svm_queue_lock (q=0x0) at /home/ubuntu/vpp/src/svm/queue.c:101 |#2 svm_queue_add (q=0x0, elem=0x7fffa76c2de0 "\210\365\006\060\001", nowait=0) at /home/ubuntu/vpp/src/svm/queue.c:274 |#3 0x00007ffff6e131e3 in vl_api_send_msg (rp=<optimized out>, elem=<optimized out>) at /home/ubuntu/vpp/src/vlibmemory/api.h:43 |#4 send_sw_interface_details (am=<optimized out>, rp=<optimized out>, swif=0x7fffb957a0bc, interface_name=<optimized out>, context=<optimized out>) | at /home/ubuntu/vpp/src/vnet/interface_api.c:353 |#5 0x00007ffff6e0edeb in vl_api_sw_interface_dump_t_handler (mp=<optimized out>) at /home/ubuntu/vpp/src/vnet/interface_api.c:412 |#6 0x00007ffff7daeb48 in msg_handler_internal (am=<optimized out>, the_msg=0x7fffb839a5e0, trace_it=<optimized out>, do_it=1, free_it=0) | at /home/ubuntu/vpp/src/vlibapi/api_shared.c:501 |#7 vl_msg_api_socket_handler (the_msg=0x7fffb839a5e0) at /home/ubuntu/vpp/src/vlibapi/api_shared.c:790 |#8 0x00007ffff7d7c608 in vl_socket_process_api_msg (rp=<optimized out>, input_v=0x7fffa76c2de0 "\210\365\006\060\001") at /home/ubuntu/vpp/src/vlibmemory/socket_api.c:212 |#9 0x00007ffff7d89ff1 in vl_api_clnt_process (vm=<optimized out>, node=<optimized out>, f=<optimized out>) at /home/ubuntu/vpp/src/vlibmemory/vlib_api.c:405 |#10 0x00007ffff53bf9a7 in vlib_process_bootstrap (_a=<optimized out>) at /home/ubuntu/vpp/src/vlib/main.c:1490 |#11 0x00007ffff4da0b2c in clib_calljmp () from /home/ayourtch/vpp/build-root/install-vpp-native/vpp/lib/libvppinfra.so.21.06 |#12 0x00007fffa99a4d90 in ??

2020-05-25api: add new stream message conventionOle Troan1-0/+22
Instead of having to wrap dump/detail calls in control ping, send details messages in between a normal reply / request pair. As expressed in the below service statement. Example: service { rpc map_domains_gets returns map_domains_get_reply stream map_domain_details; }; define map_domains_get { u32 client_index; u32 context; u32 cursor; }; define map_domains_get_reply { u32 context; i32 retval; u32 cursor; }; To avoid blocking the main thread for too long, the replies are now sent in client message queue size chunks. The reply message returns VNET_API_ERROR_EAGAIN when there is more to read. The API handler must also include a "cursor" that is used to the next call to the get function. API handler example: REPLY_AND_DETAILS_MACRO (VL_API_MAP_DOMAINS_GET_REPLY, mm->domains, ({ send_domain_details (cursor, rp, mp->context); })); The macro starts from cursor and iterates through the pool until vl_api_process_may_suspend() returns true or the iteration reaches the end of the list. Client Example: cursor = 0 d = [] while True: rv, details = map_domains_get(cursor=cursor) d += details if rv.retval == 0 or rv.retval != -165: break cursor = rv.cursor or the convenience iterator: for x in vpp.details_iter(vpp.api.map_domains_get): pass or list(details_iter(map_domains_get)) Change-Id: Iad9f6b41b0ef886adb584c97708dd91cf552749e Type: feature Signed-off-by: Ole Troan <ot@cisco.com>
