2021-12-14api: verify message size on receiptKlement Sekera1-8/+21
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.

Add vl_client_connect_to_vlib_thread_fn (...) and export the memory_client_main_t definition. If you use this new API, make sure not to miss the setjmp / longjmp dance shown in .../src/vlibmemory/memory_client.c:rx_thread_fn(...), which is required for the rx pthread to terminate cleanly; please process client delete reply messages in the rx thread...

2019-08-02vppinfra: Expose function setting __os_thread_indexNathan Skrzypczak1-20/+1
Type: feature This is needed when creating pthreads in client applications, they need a way to set __os_thread_index per thread that does not conflict with the binary API thread index. If __os_thread_index is left to 0 in two client pthreads and they call vl_msg_api_alloc and vec_resize at the same time it can fail due to them sharing (and push/poping) the same clib_per_cpu_mheaps slot.

2019-04-16API: Handle pthread cond signal case where signal is missed.Ole Troan1-2/+2
Especially on a single core setup the RX thread could signal the main thread that it was done, before main thread listened to the signal. Change-Id: Ib70337b21bcf77787ce4ee0aa9cf80c6da2215af Signed-off-by: Ole Troan <ot@cisco.com>
2019-04-10API: Fix shared memory only action handlers.Ole Troan1-0/+1
Some API action handlers called vl_msg_ai_send_shmem() directly. That breaks Unix domain socket API transport. A couple (bond / vhost) also tried to send a sw_interface_event directly, but did not send the message to all that had registred interest. That scheme never worked correctly. Refactored and improved the interface event code. Change-Id: Idb90edfd8703c6ae593b36b4eeb4d3ed7da5c808 Signed-off-by: Ole Troan <ot@cisco.com>

2018-12-05bapi: add options to have vpp cleanup client registrationFlorin Coras1-2/+3
A client can send a memclnt delete message and ask vpp to cleanup the shared memory queue. Obviously, in this case no delete reply is sent back to the client. Change-Id: I9c8375093f8607680ad498a6bed0690ba02a7c3b Signed-off-by: Florin Coras <fcoras@cisco.com>

2018-06-05VPP API: Memory traceOle Troan1-16/+27
if you plan to put a hash into shared memory, the key sum and key equal functions MUST be set to constants such as KEY_FUNC_STRING, KEY_FUNC_MEM, etc. -lvppinfra is PIC, which means that the process which set up the hash won't have the same idea where the key sum and key compare functions live in other processes.

2018-02-02vlmemory/svm: fix client detach from svm regionFlorin Coras1-3/+4
Clients cannot know at svm region detach time if the shm backing files have been recreated (e.g., if vpp restarts) and therefore should not try to unlink them. Otherwise, terminating clients attached to previous instantiations of a re-allocated region end up making the new instance un-mappable by removing its backing file.

2018-01-22svm: queue sub: Add conditional timed waitMohsin Kazmi1-2/+2
On reviece side svm queue only permits blocking and non-blocking calls. This patch adds timed wait blocking functionality which returns either on signal/event or on given time out. It also preserves the original behavior, so it will not hurt client applications which are using svm queue.

2017-10-18CSIT-844: fix binary api rx pthread heap push/popDave Barach1-3/+22
We need to push/pop the rx pthread's heap without affecting other thread(s). Search clib_per_cpu_mheaps, locate an unused slot. Duplicate the main thread heap pointer in that slot, and set __os_thread_index appropriately. Miscellaneous cleanups. Print exec_inband results as a vector, instead of as a format string. Don't bail out of vpp_api_test with results pending, e.g. at the end of a vpp_api_test script. Even though vpp will eventuallly garbage-collect them, We don't want to leave allocated reply messages lurking in the api message allocation rings...
