eXosip2 (5.3.0) - 2021-11-22 * rewrite socket error management in order to apply them to all pending ICT and NICT transactions - with previous code, some transactions won't see the transport-error and will fail with unnecessary delay. * add time information in cb_xixt_kill_transaction callback for debugging * eXosip_lock will now include read on sockets * [TLS] allow to accept wildcard with a new bit in tls_verify_client_certificate * [TLS] disable loading OS certifiate with a new bit in tls_verify_client_certificate * [TLS] I beleive there is no reason to cut packet in 500 bytes chunks on ios * [EXOSIP_OPT_SET_CONTACT_DIALOG_EXTRA_PARAMS] new option to set Contact parameters in request/answers dialogs * [AMSIP_OPTION_SET_SIP_INSTANCE] allow any value inside +sip.instance instead of only urn:uuid * [epoll] fix eXosip_event_wait when using epoll implementation where events are distributed in the next eXosip_event_wait call eXosip2 (5.2.1) - 2020-05-21 * [ENABLE_MAIN_SOCKET] fix epoll mechanism for server socket with TCP and TLS * [crash] check scheme upon processing 3xx * [ssl] fix to be compatible with libressl * [ssl] https://savannah.nongnu.org/patch/?10046 compatibility with openssl below 1.1.0 * fix when Content-Type indicates application/sdp, but there is no body * [TLS] modify the code for TLS validation in order to improve logs and details on the connection * use time_t instead of int for r_retry_after_delay variable [fix 1367a34ca commited on March 1st] * eXosip_default_action will return OSIP_RETRY_LIMIT when limit is reached * make sure to obey the Retry-After header from REGISTER reply * use newer osip_timersub MACRO * [bug#60024] fix openssl usage to always use callback mode for private key password, even when missing * eXosip_reset_transports was not effective any more since [5.1.2] [commit 705643fa 2020-07-07] [do not use unless you understand it] * [windows] a HANDLE is leaked when loading trusted certificates * dp layer: handle WSAEMSGSIZE when buffer is too short for complete incoming messag * cleaner code to retreive an SDP from a SIP message * fix crash when ENABLE_MAIN_SOCKET is defined and epoll is used eXosip2 (5.2.0) - 2020-11-10 * fix memory and socket leak [major] [affected TCP, TLS, UDP: since 5.1.2, need update asap] * fix to make sure a non yet established TLS descriptor with read descriptor set will be processed when no outgoing transaction is in a state to handle it [since 5.1.2] * fix SRV rotation for TLS [was rotating TCP records instead of TLS] [since 5.1.2] * fix duplicate packets for TCP and TLS when several outgoing NICT are happening at the same time [since 5.1.2] * add outbound proxy parameter in sip_monitor tool * ABI update: modification of "eXosip_tls_ctx_t" extend the structure to set - cipher list - add TLS openssl flags (to disable TLSv1, TLSv1.1, etc...) - add DTLS openssl flags (to disable DTLSv1, etc...) eXosip2 (5.1.3) - 2020-08-25 * EXOSIP_OPT_FORCE_CONNECTIONREUSE; new option to force reusing established socket for ACK and dialog message * tls: fix building DH parameter with 5.1.2 and openssl < 1.1.0 eXosip2 (5.1.2) - 2020-08-20 * tls: use RFC 5114 dh param with 2048 bits size. * tls: use 2048 bits for ephemeral RSA key genearation. * tls: use SSL_OP_NO_COMPRESSION to make sure it's disabled. * tls: use SSL_OP_NO_TICKET to disable ticket. * tls: use HIGH:!COMPLEMENTOFDEFAULT:!kRSA:!PSK:!SRP cipher list for higher security and less ciphers * fix possible race condition in sample code [sip_reg and sip_monitor] * new format style using clang-format. * reduce and rewrite logs for readability. * fix broken epoll implementation. (DO NOT USE 5.1.1 with epoll) * rewrite UDP/TCP/TLS (and DTLS untested) for both select and epoll mode. complete rewrite of socket (c-ares and UDP/TCP/TLS) in order to accelerate socket esablishement, and correctly handle socket failure. The change also help to recover faster after a socket failure and to switch to the next SRV record available. This last feature was previously broken. * Fix NAPTR/SRV on windows when CARES is not used. (not advised) * ACK sent out of transaction with no existing connection may be sent later. (TCP/TLS) * Upon TLS loss, try to use domain or NAPTR SNI when TLS connection is not initiated by an outgoing transaction. * sip_monitor: new tool to monitor sip service * add support for authentication using SHA-256 (openssl required) * only use first supported proposed authentication when same realm is used * fix: upon UDP errors, like ICMP buffer size may reach abnormal values (avoid useless reallocation) eXosip2 (5.1.1) - 2020-01-16 * new API: Generate random string: (low entropy, only hexa) int eXosip_hexa_generate_random(char *val, int val_size); Generate random string: (high entropy when compiled with openssl) int eXosip_byte_generate_random(char *val, int val_size) * provide more entropy with eXosip_byte_generate_random (with openssl when available). * fix TLS security issue reported by Alexander Traud regarding hostname validation when using NAPTR/SRV. * add support for epoll (detected by configured) // becomes the default on linux platforms with autotools * fix bug #56839: The cnonce should not be static -this is identified as replay attack by some services-. * fix tcp and tls connection failure detection (accelerate error detection and recovery) * fix: fixed a crash with DTLS eXosip2 (5.1.0) - 2019-03-27 * minor API update: API parameter change: eXosip_call_build_ack/eXosip_call_send_ack API to use tid instead of did as parameter. * new API: add an API to insert one extra header in BYE: int eXosip_call_terminate_with_header(struct eXosip_t *excontext, int cid, int did, const char *header_name, const char *header_value); void eXosip_dnsutils_release(struct osip_naptr *naptr_record); required after usage of eXosip_dnsutils_naptr. * new OPTION: EXOSIP_OPT_SET_SESSIONTIMERS_FORCE option to force session timer to be used when remote side does not support it. * structure change: new param in eXosip_tls_credentials_t for pinning: "public_key_pinned". A file with the expected public key of server. If you use eXosip_tls_ctx_t/eXosip_tls_credentials_t/EXOSIP_OPT_SET_TLS_CERTIFICATES_INFO, you need to recompile. * fix processing response out of transaction. (avoid incorrect logs and extra work) * fix https://savannah.nongnu.org/bugs/?54628 where ACK was only retransmitted for initial outgoing INVITE. fix: retransmit ACK for both initial INVITE and re-INVITE. fix: retransmit ACK for 2xx from forking (with a BYE) even if call does not exist. ACK for "old transaction" within the established dialog won't be retransmitted because the parameter only hold the latest ACK. * fix bug report: https://savannah.nongnu.org/bugs/index.php?54624 another patch to fix more issue related to cseq & PRACK. The newer code better handle forking use-case with PRACK. The newer code better handle several 1xx from same user. * fix bug report: https://savannah.nongnu.org/bugs/index.php?54624 cseq wasn't increasing after a PRACK. * improve portability code, detection of headers, windows compilation detection, sockaddr_storage was not correctly defined. * fix udp layer: set ipbuf before using it. * fix: allow socket descriptor to be 0 (posix requirement). * fix: compile with any openssl version. * allow compilation with OPENSSL_NO_DH, OPENSSL_NO_RSA, OPENSSL_NO_ECDH and/or OPENSSL_NO_DEPRECATED. * remove old windows specific RSA obsolete code. * add in eXtl_tls.c some explanations on usage of TLS with eXosip2. READ THEM. * improve reliability for naptr/srv lookup (but still a short time). * fix/improve _eXosip_mark_registration_expired: it was working correctly only if registration had previously failed. * fix: attach call/dialog to CANCEL transaction (so EXOSIP_CALL_MESSAGE_ANSWERED will be received instead of EXOSIP_MESSAGE_ANSWERED). * windows: fix DnsQuery to use UTF8 even if compiled without UNICODE (not applicable if you use c-ares). * windows: add ENUM capability and improve NAPTR/SRV record (not applicable if you use c-ares). * windows: you should use c-ares AND you should compile with UNICODE. (much better). * add ability to define a dnsserver when doing NAPTR and SRV record (c-ares only). * format of domain string for "eXosip_dnsutils_naptr" is "domain.com!+AUS|IP_DNSSERVER". * fix for on android, DNS are not available any more (restricted access) (c-ares only). * add support ENUM and regex for res_query API (not applicable if you use c-ares). * sync with newer osip: use newer osip_naptr & osip_srv_record structures to hold ENUM sip result and improvements to retreive (and release) it via eXosip_dnsutils_naptr and eXosip_dnsutils_release APIs. * TLS improvments: simplify client and server config, add ECDH cipher suite if missing, password for private key is optional, add support for public key pinning. * improve to report EXOSIP_CALL_NOANSWER upon transport error for INVITE for faster detection. * fix possible memory leak for X509 server certificate. * fix crash if dialog has been already closed between 200ok and a received BYE. * improve windows pipe replacement (use a free allocated port automatically). * fix to optimize detection of TCP or TLS establishement, fix to optimize sending REGISTER after establishement. * patch for call transfer to keep dialog after BYE, in order to be able to handle incoming/outgoing NOTIFY within calls after BYE. * handle incoming UPDATE from alternative dialogs in early dialog mode. * fix to reject any NOTIFY without established dialog coming later than 64 seconds after initial SUBSCRIBE. * After a NAPTR query, some DNS server returns SUCCESS without NAPTR answers. In such use-case, fallback to manual SRV records. * add SOCK_CLOEXEC option to sockets // add missing SO_KEEPALIVE options on TLS socket. * EXOSIP_OPT_ENABLE_IPV6 now support 0(ipv4 only), 1(ipv6 only) and 2(ipv4 OR ipv6). With option 2, choice is made based on DNS and the stack can fallback between IPv4 and IPv6. * fix possible memory leak when using wrong tid for eXosip_insubscription_send_answer. * fix possible memory leak upon allocation error. * fix leak upon syntax error in parameters provided for PUBLISH. * fix leak upon syntax error in parameters provided for REGISTER. * increase size of proto_ifs for IPv6 local address. * RFC 2617 erratum: Errata ID: 1649 (minor issue). * _exosip_isipv4addr: fix checking IPv4 address (minor issue). * other minor updates. eXosip2 (5.0.0) * major API update: add a new parameter to eXosip_call_build_prack in order to create the PRACK for this specific response and not for the latest. * major API update: removal of eX_refer.h API.
