Hi,
I am planning to use the VPP Host stack for the SSL Proxy solution.
Currently doing a few prototypes to understand internal details of Host
Stack.I have written 2 simple Apps (Server) with POSIX APIs (Please find
the attached files). one is with single threaded and another is with Multi
threaded.Client connects the APP and downloads the test.html file.(curl -v http://10.10.10.10:8080/test.html). With a single threaded app able to download the file multiple times without any issue. With a Multithreaded app , able to connect only once and download the file, if I try to connect again it is stuck at TCP-ESTABLISHED state.Not getting HTTP/1.1 GET payload to the application. vpp# show event-logger 5 of 131072 events in buffer, logger running 14991.353354343: lcl: 10.10.10.10:8080 14991.353354689: rmt: 192.168.10.1:42272 14991.353354769: syn-rx: cidx 1 sidx 0 irs 4130977040 14991.353354795: state: syn-rcvd 14991.353558089: state: established vcl { heapsize 64M segment-size 4000000000 add-segment-size 4000000000 rx-fifo-size 4000000 tx-fifo-size 4000000 max-workers 25 app-scope-local app-scope-global app-socket-api /var/run/vpp/app_ns_sockets/default use-mq-eventfd } session { use-app-socket-api enable evt_qs_memfd_seg } Am I missing any configuration for Multithreaded App ? Is there any document where I can find which POSIX calls are supported ? VPP Main thread and APPlication are running on 2 different CPUs. I am using the VPP Latest Version. vpp# show threads ID Name Type LWP Sched Policy (Priority) lcore Core Socket State 0 vpp_main 163832 other (0) 2 0 0 1 vpp_wk_0 workers 163834 other (0) 3 0 0 vpp# show version vpp v26.02-rc0~246-gc9d32e020 built by root on ubuntu at 2025-11-29T04:05:56 How to enable the debugging logs for VCL? with VPP_VCL_ELOG enabled, did not see the logs. Thanks Farooq.
