[kamailio/kamailio] Write Buffer too small (#2240)
by Natzy 06 Mar '20

06 Mar '20

### Description  We're trying to connect the same subscriber with Kamailio for load testing. Sometimes it registers successfully but sometimes it throws the following error. ### Troubleshooting >From my understanding by checking the source code, TLS_WR_MBUF_SZ is set as 65536 by default. This is the reason for "write buffer too small". Can someone help me with how to change that? #### Reproduction  I don't exactly know how to reproduce as some the clients pass and some fail. #### Debugging Data  ``` (paste your debugging data here) ``` #### Log Messages  BUG: tls [tls_server.c:849]: tls_encode_f(): write buffer too small (65536/65536 bytes) ERROR: websocket [ws_frame.c:300]: encode_and_send_ws_frame(): sending WebSocket frame ERROR: websocket [ws_frame.c:800]: ws_frame_transmit(): sending message NOTICE: <script>: WebSocket connection from a.b.c.d:1234 has closed ERROR: registrar [reply.c:745]: reg_send_reply(): failed to send 200 OK ERROR: <core> [core/tcp_main.c:3502]: handle_ser_child(): received CON_ERROR for 0x7f9472eec990 (id 100), refcnt 4, flags 0x4018 NOTICE: <script>: Error in saving location data WARNING: sl [../../core/forward.h:173]: msg_send_buffer(): TCP/TLS connection for WebSocket could not be found ERROR: sl [sl_funcs.c:362]: sl_reply_error(): stateless error reply used: I'm terribly sorry, server error occurred (1/SL) WARNING: <core> [core/tcp_read.c:1716]: handle_io(): F_TCPCONN connection marked as bad: 0x7f9472eec990 id 100 refcnt 1 #### SIP Traffic  ### Possible Solutions  Need to increase the default tls write buffer size from 65536. I think it is set as "#define TLS_WR_MBUF_SZ 65536" ### Additional Information * **Kamailio Version** - output of `kamailio -v` version: kamailio 5.0.8 (x86_64/linux) c35e69 flags: STATS: Off, USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, Q_MALLOC, F_MALLOC, TLSF_MALLOC, DBG_SR_MEMORY, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLACKLIST, HAVE_RESOLV_RES ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144, MAX_LISTEN 16, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: c35e69 compiled on 05:04:45 Nov 25 2019 with gcc 4.8.5 * **Operating System**:  Linux 3.10.0-957.21.3.el7.x86_64 #1 SMP Tue Jun 18 16:35:19 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux CentOS Linux release 7.7.1908 (Core) -- You are receiving this because you are subscribed to this thread.

dev question related to generate_avps()
by Stefan Mititelu 06 Mar '20

06 Mar '20

Hi, I want to ask you if it would make sense for kamailio upstream code to generate_avps() (got from the database) also when the user failed to register? Please have a look in src/modules/auth_db/authorize.c line 303. If it makes sense, I'll do a pull request for it. Thank you, Stefan

Re: [sr-dev] Regarding MIPS Compilation
by Henning Westerholt 06 Mar '20

Hello, please keep the list in CC. it looks that it still tries to compile the x86 code, and not the MIPS one. What do you get when you execute “make cfg” on your system – this is what I get on 64 Linux: henning@static:~/repositories/kamailio/src$ make cfg target architecture <x86_64>, host architecture <x86_64> If you have the possibility to test a native compilation on the platform, maybe this is easier to do as well. It will take some time to compile, but still not too much.
