[kamailio] escape transformation chokes on UTF characters (#549)

by apogrebennyk

Version 4.3.4 fails to escape the string that contains Unicode characters: $var(test) = "Foobar s.à.r.l."; $var(test_escaped) = $(var(test){s.escape.user}); Mar 23 16:00:28 sp1 (local7.err) proxy[27853]: ERROR: <core> [strcommon.c:241]: escape_user(): invalid escaped character <4294967235> Mar 23 16:00:28 sp1 (local7.err) proxy[27853]: ERROR: <core> [lvalue.c:345]: lval_pvar_assign(): non existing right pvar Mar 23 16:00:28 sp1 (local7.err) proxy[27853]: ERROR: <core> [lvalue.c:405]: lval_assign(): assignment failed at pos: (701,35-701,97) is there a way to ignore those characters or is it something we have to live with? Some background: we are storing some user-defined data as custom attributes in acc src_leg/dst_leg. As you know the fields in src/dst_leg are pipe-separated. In order to prevent the user from hijacking the attributes we have devided to escape the user-provided fields. This is when we realized that this is limited to latin1 encoding. In theory we can escape it using lua just wanted to avoid the overhead of calling the interpreter too often. --- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] QMalloc: TCP Memory Allocation Failures (#562)

by Phil Lavin

Experiencing an issue with QMalloc when Kamailio receives a lot of subscriptions (dialog-info) in a short period of time. The following is reported in logs and the TCP (TLS) connection fails: ```Apr 4 18:06:04 ua-proxy-01 /usr/local/sbin/kamailio[28456]: ERROR: <core> [tcp_main.c:959]: tcpconn_new(): mem. allocation failure Apr 4 18:06:04 ua-proxy-01 /usr/local/sbin/kamailio[28456]: ERROR: <core> [tcp_main.c:3977]: handle_new_connect(): tcpconn_new failed, closing socket``` A snapshot of SHM usage from around the time of the connection is as follows: ```shmem:fragments = 39604 shmem:free_size = 49473400 shmem:max_used_size = 67108696 shmem:real_used_size = 17635464 shmem:total_size = 67108864 shmem:used_size = 9423760``` Kamailio `-I` output is as follows: ```Print out of kamailio internals Version: kamailio 4.3.4 (x86_64/linux) b2843e Default config: /usr/local/etc/kamailio/kamailio.cfg Default paths to modules: /usr/local/lib64/kamailio/modules Compile 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, DBG_QM_MALLOC, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLACKLIST, HAVE_RESOLV_RES MAX_RECV_BUFFER_SIZE=262144 MAX_LISTEN=16 MAX_URI_SIZE=1024 BUF_SIZE=65535 DEFAULT PKG_SIZE=8MB DEFAULT SHM_SIZE=64MB ADAPTIVE_WAIT_LOOPS=1024 TCP poll methods: poll, epoll_lt, epoll_et, sigio_rt, select Source code revision ID: b2843e Compiled with: gcc 4.7.2 Compiled on: 17:56:04 Apr 4 2016 Thank you for flying kamailio!``` Once it has gotten in this state, TCP connections will no longer work, regardless of how low the SHM gets. Other connections (UDP) and subscriptions (dialog-info) work correctly at this time. There are no other OOM errors in the logs. The only thing that will resolve the issue is to restart Kamailio. Compiling to use FMalloc (`MEMMNG=0 MEMDBG=1 make cfg`) appears to resolve the issue. Kamailio `-I` output as follows: ```Print out of kamailio internals Version: kamailio 4.3.4 (x86_64/linux) b2843e Default config: /usr/local/etc/kamailio/kamailio.cfg Default paths to modules: /usr/local/lib64/kamailio/modules Compile 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, F_MALLOC, DBG_F_MALLOC, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLACKLIST, HAVE_RESOLV_RES MAX_RECV_BUFFER_SIZE=262144 MAX_LISTEN=16 MAX_URI_SIZE=1024 BUF_SIZE=65535 DEFAULT PKG_SIZE=8MB DEFAULT SHM_SIZE=64MB ADAPTIVE_WAIT_LOOPS=1024 TCP poll methods: poll, epoll_lt, epoll_et, sigio_rt, select Source code revision ID: b2843e Compiled with: gcc 4.7.2 Compiled on: 18:07:19 Apr 4 2016 Thank you for flying kamailio!``` At the time the TCP connection works correctly, the SHM usage is: ```shmem:fragments = 40669 shmem:free_size = 51558136 shmem:max_used_size = 67107816 shmem:real_used_size = 15550728 shmem:total_size = 67108864 shmem:used_size = 10045520``` --- You are receiving this because you are subscribed to this thread.

shared memory between multiple forks in custom module

by Cockhootec Yahrabee

Hi guys! I am developing custom kamailio module in which I am parsing some properties from incoming SIP messages and I am persisting them within linked list of my custom structure. I am also accessing this linked list and I am deciding on the data which part of my program will be executed. I am also at some point removing items from linked list. I was testing my module only in single fork while I was developing it but now I want to use it with multiple forks. My linked list is allocated via `shm_malloc` function and all data within it as well. I assumed that I need to allocate some lock as well so at the time of creation single node I am allocating lock by http://www.asipto.com/pub/kamailio-devel-guide/#c03lock_init Unfortunately I didn't find anywhere how should I access this kind of data. Do I need to check every time I want to access my structure if the lock is unlocked and if I am accessing it I need to lock it? Or are these actions performed by kamailio internally? Another question is if it is sufficient to have one lock per structure or I need to lock every structure within that structure? For instance: typedef struct node { char *some_property; another_node_t *some_other_property; another_node_t *another_property; struct node *prev; struct node *next; gen_lock_t *lock; } node_t; In this scenario do I need create `gen_lock_t` also within `another_node_t` structure? Thanks in advance for any help
