2021-03-29svm session vcl: per app rx message queuesFlorin Coras11-104/+518
Add option to use per app private segments for app to vpp message queues, as opposed to exposing internal message queues segment. When so configured, internal message queues are still polled by the session queue node but external app message queues are handled by a new input node (appsl-rx-mqs-input) that runs in interrupt state. Signaling of the node, when mqs receive new messages, is done through eventfds epolled by worker epoll input nodes.

Sending the bogus acl_add_replace message with count=~0 will result in an overflow of "expected_len" field which is a u32, thus the message will pass the validation when it should not.

2021-03-25stats: python vpp_stats rewrite to access stat segment directlyOle Troan11-419/+567
This module implement Python access to the VPP statistics segment. It accesses the data structures directly in shared memory. VPP uses optimistic locking, so data structures may change underneath us while we are reading. Data is copied out and it's important to spend as little time as possible "holding the lock". Counters are stored in VPP as a two dimensional array. Index by thread and index (typically sw_if_index). Simple counters count only packets, Combined counters count packets and octets. Counters can be accessed in either dimension. stat['/if/rx'] - returns 2D lists stat['/if/rx'][0] - returns counters for all interfaces for thread 0 stat['/if/rx'][0][1] - returns counter for interface 1 on thread 0 stat['/if/rx'][0][1]['packets'] - returns the packet counter for interface 1 on thread 0 stat['/if/rx'][:, 1] - returns the counters for interface 1 on all threads stat['/if/rx'][:, 1].packets() - returns the packet counters for interface 1 on all threads stat['/if/rx'][:, 1].sum_packets() - returns the sum of packet counters for interface 1 on all threads stat['/if/rx-miss'][:, 1].sum() - returns the sum of packet counters for interface 1 on all threads for simple counters Type: refactor Signed-off-by: Ole Troan <ot@cisco.com> Change-Id: I1fe7f7c7d11378d06be8276db5e1900ecdb8f515 Signed-off-by: Ole Troan <ot@cisco.com>
2021-03-24tests: add vpp test dirs to PYTHONPATHDave Wallace1-4/+10
- Required to relocate test infra modules to be co-located in feature test directory. - Remove/regenerate build-root/build-test/src/ soft links when running make test to allow re-running 'make test' after moving source files. - Suppress annoying 'ls' error message when gathering test source files caused by 'c' test application directory being named 'test'. - Use PYTHONPYCACHEPREFIX to generate all compiled source under build-root/build-test. This only works for python 3.8 or greater, but existing 'make test-wipe' target cleans up in-situ __pycache__ directories for older python versions.

2021-03-19api: Avoid the usage of the freed registration by the API callsAndrew Yourtchenko2-23/+52
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 ??
