2024-09-26vlib: process node scheduler reworkDamjan Marion1-10/+11
This commit allow use od cooperative multitasking with multiple descheduling reasons (i.e. event wait and suspend) inside the same process node. In previus code remote node will wake up process node by sending event evein if process node is waiting in vlib_process_ssupend(). This change also allowed new vlib_process_yield() API which deschedules current process and it puts it into the end of queue.

2024-05-07api: add to_net parameter to endian messagesOle Troan3-6/+6
The VPP API auto-generated endian conversion functions are intended to be symmetrical. They are used both by the API client and the API server. Called on send to convert from host endian to network endian and on receive to convert back. For variable length arrays, we have to iterate over the array and call a more specific handler for the array type. Unfortunately the length of the array is part of the api definition, and if it's endian swapped prior to the for loop, unexpected behaviour will ensue. There was an earlier fix, for some specific messages, but unfortunately that only fixed the problem from the VPP (server) side. This adds a new parameters to the endian handler, so the boundary argument to the loop can be treated differently depending on if this message is to the network or from the network.

2024-01-29api: provide api definition over apiOle Troan1-0/+2
This patch allows a client to bootstrap itself by downloading the JSON API definitions over the API itself. This patch enables it for Python (probably need a dynamic language). Call VPPApiClient with the new bootstrapapi=True parameter. Example (Python): from vpp_papi import VPPApiClient vpp = VPPApiClient(bootstrapapi=True) rv = vpp.connect("foobar") assert rv == 0 print(f'SHOW VERSION: {vpp.api.show_version()}') vpp.disconnect() Type: feature Change-Id: Id903fdccc82b2e22aa1994331d2c150253f2ccae Signed-off-by: Ole Troan <otroan@employees.org>

2021-03-19api: Avoid the usage of the freed registration by the API callsAndrew Yourtchenko1-0/+1
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/+37
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>

2020-05-04misc: binary api fuzz test fixesDave Barach3-2/+28
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

vat_socket_connect(...) needs to set the api main client index. The M2 helper macro needed to allocate a buffer of size sizeof(*mp) + n, not sizeof(*mp). Type: fix Signed-off-by: Dave Barach <dave@barachs.net> Change-Id: I7abf35d2ba045d82765bd27f88899287fd351602
2020-02-26api: add macro that zeros out api reply bufferPaul Vinciguerra1-0/+32
Add macros REPLY_MACRO2_ZERO, REPLY_MACRO3_ZERO that zeros the buffer before the values are set. This way if say, a u8[64] field is only filled with 10 octets, the previous buffers trailing contents are not sent.

2020-02-26api: improve api string safetyJakub Grajciar2-13/+34
- Remove vl_api_from_api_string to prevent use of not nul-terminated strings. - Rename vl_api_from_api_to_vec -> vl_api_from_api_to_new_vec to imply a new vector is created. NOT nul terminated. - Add vl_api_from_api_to_new_c_string. Returns nul terminated string in a new vector. - Add vl_api_c_string_to_api_string. Convert nul terminated string to vl_api_string_t - Add vl_api_vec_to_api_string. Convert NON nul terminated vector to vl_api_string_t Type: fix Signed-off-by: Jakub Grajciar <jgrajcia@cisco.com> Change-Id: Iadd59b612c0d960a34ad0dd07a9d17f56435c6ea Signed-off-by: Jakub Grajciar <jgrajcia@cisco.com>
