2018-08-03svm: add support for eventfd signaling to queueFlorin Coras2-11/+9
Support the use of eventfds to signal queue updates between consumer and producer pairs. Change-Id: Idb6133be2b731fff78ed520daf9d2e0399642aab Signed-off-by: Florin Coras <fcoras@cisco.com>

2018-06-27gcc8 and Wstringop-truncationMarco Varlese1-4/+6
gcc8 introduced a new warning (Wstringop-truncation) which in our case is being treated as error. Disabling the warning globally might introduce bugs related to string truncation which are not desired by the developer (e.g. bug). Instead, this patch disables the warning only for those occurences which have been verified to be non-bugs but the desired behaviour as per developer will.

2018-06-26Fix api trace replay of handler to pass vm parameterJohn Lo1-2/+2
I suppose most API handlers do not use vm parameter so it has not been a problem so far. Now vl_api_vnet_set_ip6_ethernet_neighbor() was crashing when called from api trace replay because either of ip_neighbor_add_del_t_handler() vnet_arp_set_ip4_over_ethernet() need vm to be correct when it calls vlin_time_now() to update the neighbor timestamp.

2018-06-05VPP API: Memory traceOle Troan2-16/+28
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 Coras4-8/+23
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.

2018-01-23VPPAPIGEN: vppapigen replacement in Python PLY.Ole Troan1-1/+1
This is a version of the VPP API generator in Python PLY. It supports the existing language, and has a plugin architecture for generators. Currently C and JSON are supported. Changes: - vl_api_version to option version = "major.minor.patch" - enum support - Added error checking and reporting - import support (removed the C pre-processor) - services (tying request/reply together) Version: option version = "1.0.0"; Enum: enum colours { RED, BLUE = 50, }; define foo { vl_api_colours_t colours; }; Services: service { rpc foo returns foo_reply; rpc foo_dump returns stream foo_details; rpc want_stats returns want_stats_reply events ip4_counters, ip6_counters; }; Future planned features: - unions - bool, text - array support (including length) - proto3 output plugin - Refactor C/C++ generator as a plugin - Refactor Java generator as a plugin Change-Id: Ifa289966c790e1b1a8e2938a91e69331e3a58bdf Signed-off-by: Ole Troan <ot@cisco.com>
2018-01-22svm: queue sub: Add conditional timed waitMohsin Kazmi2-3/+3
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.

2018-01-11api: remove transport specific code from handlersFlorin Coras1-4/+4
This does not update api client code. In other words, if the client assumes the transport is shmem based, this patch does not change that. Furthermore, code that checks queue size, for tail dropping, is not updated. Done for the following apis: Plugins - acl - gtpu - memif - nat - pppoe VNET - bfd - bier - tapv2 - vhost user - dhcp - flow - geneve - ip - punt - ipsec/ipsec-gre - l2 - l2tp - lisp-cp/one-cp - lisp-gpe - map - mpls - policer - session - span - udp - tap - vxlan/vxlan-gpe - interface VPP - api/api.c OAM - oam_api.c Stats - stats.c Change-Id: I0e33ecefb2bdab0295698c0add948068a5a83345 Signed-off-by: Florin Coras <fcoras@cisco.com>

2017-12-15VPP-1102: fix dangling references in RPC handlingDave Barach2-27/+40
Queue RPC calls and send them from the main dispatch loop. As things stood, if the vpp main input queue filled, worker threads could enter a barrier-sync spin-wait in the middle of processing a frame. If thread 0 decided to recreate worker thread data structures, the worker thread(s) could easily crash. Legislate the problem out of existence by enqueueing RPC messages only from the main dispatch loop. At that point, doing a barrier-sync wait is perfectly OK.

2017-10-18CSIT-844: fix binary api rx pthread heap push/popDave Barach2-6/+27
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...

- Coverity whines about a zero-length field not being initialized. Change the struct setup to an initializer which will implicitly zero all unused fields, and add the coverity notation that should stop it whining. One or both of these should shut it up! - Fix some incorrect use of ntohl that was tainting values; in these cases htonl should have been used, and avoid a double-swap.

2017-09-25Fix sending GARP/NA on Bonded Interface Active/Backup Link Up/DownJohn Lo1-3/+27
For bonded interface in Active/Backup mode (mode 1), we need to send a GARP/NA packet, if IP address is present, on slave link state change to up or down to help with route convergence. The callback from DPDK happens in a separate thread so we need to make sure RPC call is used to signal the send_garp_na process in the main thread. Also need to fix DPDK polling so the slave links are not polled. Change-Id: If5fd8ea2d28c54dd28726ac403ad366386ce9651 Signed-off-by: John Lo <loj@cisco.com>
