git:sr_3.0: event parser: Add missing string boundary checks to event_parser func.

by Jan Janak

Module: sip-router Branch: sr_3.0 Commit: 9cb346dec84f191a53d1dbe5895f2e4276da67fe URL: http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=9cb346d… Author: Jan Janak <jan(a)ryngle.com> Committer: Jan Janak <jan(a)ryngle.com> Date: Sun Oct 18 20:49:39 2009 +0200 event parser: Add missing string boundary checks to event_parser func. The function event_parser needs to check that there is still some text left in the input string before it attempts to read the text. In addition to that the function also needs to skip any possible leading whitespace before it calls parse_params, because parse_params expects that there is no leading whitespace at the beginning of the input string.

$du stopped working

by jh＠tutpro.com

i tested with an older version of sr and found that $du setting in branch_route has not effect also there. so looks like this has nothing to do with jan's t_serial commit. anyway, this is a serious issue and should get fixed. -- juha

$du stopped working

by jh＠tutpro.com

i started testing serial forking, but before i got that far, i noticed that $du that i set in branch route, has stopped working. in branch_route i have: $du = "sip:127.0.0.1:5070"; xlog("L_INFO", "du is <$du>\n"); and i get to syslog Oct 18 14:54:54 localhost /usr/sbin/sip-proxy[18707]: INFO: du is <sip:127.0.0.1:5070> but wireshark shows that the request is not routed to $du, but according to r-uri. i'm pretty sure that this worked earlier. -- juha

git:sr_3.0: tm: Number of fixes in code and documentation for serial forking.

by Jan Janak

Module: sip-router Branch: sr_3.0 Commit: 2ea8963512096cbb54e6fdf54e7b44eacc371f34 URL: http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=2ea8963… Author: Jan Janak <jan(a)ryngle.com> Committer: Jan Janak <jan(a)ryngle.com> Date: Sun Oct 18 00:39:31 2009 +0200 tm: Number of fixes in code and documentation for serial forking. This patch improves the serial forking related code and documentation. The original code suffers from shortcommits, some of which were result of the migration to the new core. The function that decodes destination sets encoded in AVPs has been improved, because the original version did not handle properly strings with missing elements. In such case the original implementation was likely to overwrite memory, because it did not check the return value of strchr properly. The new implementation tries to handle this situation. It continues parsing as long as it can, it only requires that the request-uri string is present, all other fields are made optional and their variables are properly initialized if their values cannot be found in the AVP. There was a bug in the implementation of fr_inv_timer_next modparam in the original version, changes to the parameter value were ignored by the serial forking code. This was reported by Andrei and is now fixed by this commit. The parameter fr_inv_timer_next can now be configured at runtime with the configuration framework. Its value is in milliseconds and unlike fr_inv_timer, this timer cannot be configured separately for individual branches. Obsolete definition of INV_FR_TIME_OUT_FIRST has been removed. That macro is not used anywhere in the code, thus it is not needed. There were several places where LM_DBG printed a string and relied on the string being zero terminated, this may or may not be true in the future and this patch uses the macro STR_FMT where appropriate, which is safer. Function t_next_contacts now checks if the function decode_branch_info really returned values for the dst_uri and the path vector. If not then it calls reset_dst_uri and reset_path_vector. Previous version of the code crashed sip-router, this is likely due to the merge and updates in the sip-router core. We now use t_set_fr in t_next_contacts for setting the fr_inv_timer value to fr_inv_timer_next. This is much more efficient than creating AVPs with new timer values. Also the new value of the timer is now taken from a variable in the configuration framework, instead of just a regular global variable configured through modparam. This way we can adjust the value of the timer on the fly. Configuring it through modparam is, of course, possible too. The value of of fr_inv_timer_next is now in milliseconds, instead of seconds. That's the only possibly incompatible change. However, this is consistent with all other timers in tm module, it is more efficient and it offers better granularity. A missing call to destroy_avp has been added to t_next_contacts, in the code which is executed when no transaction exists. There, the avp should also be destroyed if all values have been exhausted and none of them had Q_FLAG set. This is a corner case which should not happen under normal circumstances, because that situation only happens if all branches have the same q value. Such AVP would not have been created by t_load_contacts and therefore t_next_contacts should not be called, but this bug may be triggered if someone uses t_next_contacts in an unexpected way and it is probably better to have it fixed. Also the code which restores the value of fr_inv_timer at the end of t_next_contacts did not work properly. This patch fixes that. It first tries to retrieve a value configured with t_set_fr, but that is not guaranteed to succeed. After that it also tries the timer AVP and finally the configuration framework. The configuration framework always yields a value, so we can always restore the timer value, but we may fail to restore individual transaction timer values set by t_set_fr. If that fails then the global value from the configuration framework is used. This is documented as a shortcomming in the README and in the code. In addition to code changes this patch also expands documentation on functions t_load_contacts and t_next_contacts, describing their operation in more detail. Also the format of the contacts AVP is now documented. Finally, there is a whole new section in the README which describes how serial/parallel forking can be achieved with t_load_contacts and t_next_contacts and provides a number of examples. --- modules/tm/README | 592 +++++++++++++++++++++++++++--------------- modules/tm/config.c | 7 +- modules/tm/config.h | 3 +- modules/tm/doc/functions.xml | 129 ++++++++-- modules/tm/doc/params.xml | 83 +++++-- modules/tm/doc/tm.xml | 218 ++++++++++++++++ modules/tm/t_serial.c | 208 ++++++++++------ modules/tm/tm.c | 2 +- 8 files changed, 900 insertions(+), 342 deletions(-) Diff: http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commitdiff;h=2ea…
