[Serusers] Re: nathelper and natping interval

[Vitali Nikolaev]

Hello Vitali,


ok.. nobody answering. or i asked something really stuped or nobody
knows :)


i traced get_all_ucontacts from dlist.c from usrloc. this function
supposed to give all contact that has specified flag set. and it
trying to compare flag in the database with: 1074111736 in :

                for (r = p->d->d_ll.first; r != NULL; r = r->d_ll.next) {
                        for (c = r->contacts; c != NULL; c = c->next) {
                                if (c->c.len <= 0)
                                        continue;
                                     /*
                                      * List only contacts that have all requested
                                      * flags set
                                      */
                                if ((c->flags & flags) != flags) {
                                ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
                                        LOG(L_ERR, "Usrloc, get_all_ucontacts: flags != flags %d != %d\n", c->flags, flags);
//                                      continue;
                                }

I am still trying to find out how it happend.. please stop me from
reading sources if I forget something really important. just
commenting "continue" is really bad in my opinion
