Default is "A" (same format used so far). - enables the ability to follow recommedations of RFC5952, section 4.3 - GH #2488 --- Modified: src/core/cfg.lex Modified: src/core/cfg.y Modified: src/core/globals.h Modified: src/core/ip_addr.c Modified: src/core/ip_addr.h --- Diff: https://github.com/kamailio/kamailio/commit/d48ce56dcd382786d9e81c5477341a8… Patch: https://github.com/kamailio/kamailio/commit/d48ce56dcd382786d9e81c5477341a8… --- diff --git a/src/core/cfg.lex b/src/core/cfg.lex index d5ac31ddd8..cc565b0151 100644 --- a/src/core/cfg.lex +++ b/src/core/cfg.lex @@ -331,6 +331,8 @@ DNS_CACHE_REC_PREF dns_cache_rec_pref /* ipv6 auto bind */ AUTO_BIND_IPV6 auto_bind_ipv6 BIND_IPV6_LINK_LOCAL bind_ipv6_link_local +IPV6_HEX_STYLE ipv6_hex_style + /* blacklist */ DST_BLST_INIT dst_blacklist_init USE_DST_BLST use_dst_blacklist @@ -775,6 +777,8 @@ IMPORTFILE "import_file" return AUTO_BIND_IPV6; } <INITIAL>{BIND_IPV6_LINK_LOCAL} { count(); yylval.strval=yytext; return BIND_IPV6_LINK_LOCAL; } +<INITIAL>{IPV6_HEX_STYLE} { count(); yylval.strval=yytext; + return IPV6_HEX_STYLE; } <INITIAL>{DST_BLST_INIT} { count(); yylval.strval=yytext; return DST_BLST_INIT; } <INITIAL>{USE_DST_BLST} { count(); yylval.strval=yytext; diff --git a/src/core/cfg.y b/src/core/cfg.y index d17540de72..7fc9817a6f 100644 --- a/src/core/cfg.y +++ b/src/core/cfg.y @@ -360,6 +360,8 @@ extern char *default_routename; %token AUTO_BIND_IPV6 %token BIND_IPV6_LINK_LOCAL +%token IPV6_HEX_STYLE + /*blacklist*/ %token DST_BLST_INIT %token USE_DST_BLST @@ -875,6 +877,13 @@ assign_stm: | DNS_CACHE_REC_PREF error { yyerror("boolean value expected"); } | AUTO_BIND_IPV6 EQUAL NUMBER {IF_AUTO_BIND_IPV6(auto_bind_ipv6 = $3);} | AUTO_BIND_IPV6 error { yyerror("boolean value expected"); } + | IPV6_HEX_STYLE EQUAL STRING { + ksr_ipv6_hex_style = $3; + if(ksr_ipv6_hex_style[0]!='a' && ksr_ipv6_hex_style[0]!='A') { + yyerror("expected \"a\" or \"A\" value"); + } + } + | IPV6_HEX_STYLE error { yyerror("string value expected"); } | BIND_IPV6_LINK_LOCAL EQUAL NUMBER {sr_bind_ipv6_link_local = $3;} | BIND_IPV6_LINK_LOCAL error { yyerror("boolean value expected"); } | DST_BLST_INIT EQUAL NUMBER { IF_DST_BLACKLIST(dst_blacklist_init=$3); } diff --git a/src/core/globals.h b/src/core/globals.h index ea16f3ae29..6e5b234353 100644 --- a/src/core/globals.h +++ b/src/core/globals.h @@ -219,6 +219,7 @@ extern char *_sr_uri_host_extra_chars; extern unsigned char *_ksr_hname_extra_chars; extern char *ksr_stats_namesep; +extern char *ksr_ipv6_hex_style; #ifdef USE_DNS_CACHE extern int dns_cache_init; /* if 0, the DNS cache is not initialized at startup */ diff --git a/src/core/ip_addr.c b/src/core/ip_addr.c index 9989063fff..4dada18ddc 100644 --- a/src/core/ip_addr.c +++ b/src/core/ip_addr.c @@ -36,6 +36,7 @@ #include "resolve.h" #include "trim.h" +char *ksr_ipv6_hex_style = "A"; struct net* mk_new_net(struct ip_addr* ip, struct ip_addr* mask) { diff --git a/src/core/ip_addr.h b/src/core/ip_addr.h index bfde61cdec..53880b0059 100644 --- a/src/core/ip_addr.h +++ b/src/core/ip_addr.h @@ -41,6 +41,8 @@ #include "dprint.h" +extern char *ksr_ipv6_hex_style; + enum sip_protos { PROTO_NONE, PROTO_UDP, PROTO_TCP, PROTO_TLS, PROTO_SCTP, PROTO_WS, PROTO_WSS, PROTO_OTHER }; #define PROTO_LAST PROTO_OTHER @@ -530,7 +532,7 @@ static inline int ip6tosbuf(unsigned char* ip6, char* buff, int len) register unsigned short hex4; int r; -#define HEXDIG(x) (((x)>=10)?(x)-10+'A':(x)+'0') +#define HEXDIG(x) (((x)>=10)?(x)-10+ksr_ipv6_hex_style[0]:(x)+'0') offset=0; if (unlikely(len<IP6_MAX_STR_SIZE))
