git:master: Kamailio compatibility: Parse and store integer message id in cseq.

by Jan Janak

Module: sip-router Branch: master Commit: ae232eca582e48f93b5a7145b52b12ce484b47ad URL: http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=ae232ec… Author: Jan Janak <jan(a)iptel.org> Committer: Jan Janak <jan(a)iptel.org> Date: Sun Mar 15 21:17:30 2009 +0100 Kamailio compatibility: Parse and store integer message id in cseq.

git:master: Kamailio compatibility: script flags

by Jan Janak

Module: sip-router Branch: master Commit: 7c7704130af7a25d3301376cc08b1eaa670d0e77 URL: http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=7c77041… Author: Jan Janak <jan(a)iptel.org> Committer: Jan Janak <jan(a)iptel.org> Date: Sun Mar 15 20:45:53 2009 +0100 Kamailio compatibility: script flags This patch adds support for script flags identical to those present in the kamailio core. Script flags is a global set of flags which preserve their value for the duration of script processing. Script flags are kept in a global variable in the sip-router core. There are several functions that can be used to manipulate the value of script flags: * setflagsval - This function sets the value of _all_ script flags at once. The new value of all the flags must be combined in the single function parameter. * setsflag - This function sets one particular script flag to 1. The function gets the index of the flag (counting from 0) as a parameter. * resetsflag - This function sets one particular script flag to 0. The function gets the index of the flag (counting from 0) as a parameter. * issflagset - Test the value of a script flag. Returns 1 if the flag is set and -1 otherwise. * getsflags - Returns the value of all script flags combined into a single variable of type flag_t. This function can be used to make a backup copy of script flags. --- flags.c | 37 +++++++++++++++++++++++++++++++++++++ flags.h | 20 ++++++++++++++++++++ 2 files changed, 57 insertions(+), 0 deletions(-) diff --git a/flags.c b/flags.c index e9f559e..70c3333 100644 --- a/flags.c +++ b/flags.c @@ -43,6 +43,10 @@ #include "clist.h" #include "mem/mem.h" +/* Script flags */ +static flag_t sflags = 0; + + int setflag( struct sip_msg* msg, flag_t flag ) { msg->flags |= 1 << flag; return 1; @@ -72,6 +76,39 @@ int flag_in_range( flag_t flag ) { } +int setsflagsval(flag_t val) +{ + sflags = val; + return 1; +} + + +int setsflag(flag_t flag) +{ + sflags |= 1 << flag; + return 1; +} + + +int resetsflag(flag_t flag) +{ + sflags &= ~ (1 << flag); + return 1; +} + + +int issflagset(flag_t flag) +{ + return (sflags & (1<<flag)) ? 1 : -1; +} + + +flag_t getsflags(void) +{ + return sflags; +} + + /* use 2^k */ #define FLAGS_NAME_HASH_ENTRIES 32 diff --git a/flags.h b/flags.h index 62b3235..30809fe 100644 --- a/flags.h +++ b/flags.h @@ -43,6 +43,26 @@ int setflag( struct sip_msg* msg, flag_t flag ); int resetflag( struct sip_msg* msg, flag_t flag ); int isflagset( struct sip_msg* msg, flag_t flag ); + +/* Script flag functions.

git:master: Functions to set/reset/test per-branch flags.

by Jan Janak

Module: sip-router Branch: master Commit: 0202608d607019077e69f432343c767f96db9372 URL: http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=0202608… Author: Jan Janak <jan(a)iptel.org> Committer: Jan Janak <jan(a)iptel.org> Date: Sat Mar 14 19:23:07 2009 +0100 Functions to set/reset/test per-branch flags. This patch adds support for setbflag,resetbflag, and isbflagset functions, these functions can be used to manipulate branch flags and they are inspired by similar functions in kamailio. There is a small difference compared to their counterparts in kamailio though. The second parameter of all these functions is of type flag_t and it is the index (counting from 0) of the flag to be manipulated. This is better aligned with how normal flags (flags.[ch]) in sip-router work. Similar functions in kamailio took the mask as the second parameter with values of flags to be manipulated. This also prevents users from modifying multiple flags at the same time accidental (note that it is not obvious from the function name that the function could do it). --- dset.c | 44 ++++++++++++++++++++++++++++++++++++++++++-- dset.h | 30 ++++++++++++++++++++++++++++++ 2 files changed, 72 insertions(+), 2 deletions(-) diff --git a/dset.c b/dset.c index e4e995a..a3a6fff 100644 --- a/dset.c +++ b/dset.c @@ -66,7 +66,7 @@ struct branch struct socket_info* force_send_socket; /* Branch flags */ - unsigned int flags; + flag_t flags; }; @@ -83,7 +83,47 @@ unsigned int nr_branches = 0; static int branch_iterator = 0; /* The q parameter of the Request-URI */ -static qvalue_t ruri_q = Q_UNSPECIFIED; +static qvalue_t ruri_q = Q_UNSPECIFIED; + +/* Branch flags of the Request-URI */ +static flag_t ruri_bflags; + + +static inline flag_t* get_bflags_ptr(unsigned int branch) +{ + if (branch == 0) return &ruri_bflags; + if (branch - 1 < nr_branches) return &branches[branch - 1].flags; + return NULL; +} + + +int setbflag(unsigned int branch, flag_t flag) +{ + flag_t* flags; + + if ((flags = get_bflags_ptr(branch)) == NULL) return -1; + (*flags) |= 1 << flag; + return 1; +} + + +int isbflagset(unsigned int branch, flag_t flag) +{ + flag_t* flags; + + if ((flags = get_bflags_ptr(branch)) == NULL) return -1; + return ((*flags) & (1 << flag)) ? 1 : -1; +} + + +int resetbflag(unsigned int branch, flag_t flag) +{ + flag_t* flags; + + if ((flags = get_bflags_ptr(branch)) == NULL) return -1; + (*flags) &= ~ (1 << flag); + return 1; +} /* diff --git a/dset.h b/dset.h index c23d4ce..a4b4f7c 100644 --- a/dset.h +++ b/dset.h @@ -30,6 +30,7 @@ #include "ip_addr.h" #include "qvalue.h" +#include "flags.h" struct sip_msg; @@ -82,5 +83,34 @@ qvalue_t get_ruri_q(void); int get_request_uri(struct sip_msg* _m, str* _u); int rewrite_uri(struct sip_msg* _m, str* _s); +/** + * Set a per-branch flag to 1. + * + * This function sets the value of one particular branch flag to 1. + * @param branch Number of the branch (0 for the main Request-URI branch) + * @param flag Number of the flag to be set (starting with 0) + * @return 1 on success, -1 on failure. + */ +int setbflag(unsigned int branch, flag_t flag); + +/** + * Reset a per-branch flag value to 0. + * + * This function resets the value of one particular branch flag to 0. + * @param branch Number of the branch (0 for the main Request-URI branch) + * @param flag Number of the flag to be reset (starting with 0) + * @return 1 on success, -1 on failure. + */ +int resetbflag(unsigned int branch, flag_t flag); + +/** + * Determine if a branch flag is set. + * + * This function tests the value of one particular per-branch flag. + * @param branch Number of the branch (0 for the main Request-URI branch) + * @param flag Number of the flag to be tested (starting with 0) + * @return 1 if the branch flag is set, -1 if not or on failure. + */ +int isbflagset(unsigned int branch, flag_t flag); #endif /* _DSET_H */

sip_resolvehost and dns_sip_resolvehost

by Ovidiu Sas

In sr core, sip_resolvehost is pointing to dns_sip_resolvehost: resolve.h:#define sip_resolvehost dns_sip_resolvehost but in k core, sip_resolvehost is a standalone method. This is creating issues due to different signatures for the two methods: k core: struct hostent* sip_resolvehost(str* name, unsigned short* port, unsigned short *proto, int is_sips, struct dns_node **dn); sr core: struct hostent* dns_sip_resolvehost(str* name, unsigned short* port, char* proto); Modules affected by this: - enum - nat_traversal - nathelper Regards, Ovidiu Sas
