    • Property Summary changed from Various fixes for DNS IPv6 to Various fixes for DNS, primarily for IPv6

  • Ticket #1974 – Description

    v2 v4  
    33334. Fixed bug of premature app callback invocation for SRV resolver by applying the same method in r5369. 
    3434 
     355. Remove DNS cache entry from resolver's hash table when app callback has a reference.[[br]] 
     36 In resolver.c {{{update_res_cache()}}}, if app callback has a reference, we only decrement the reference count of the cache entry. However, since it's not removed from the hash table, later the call to {{{pj_hash_set_np()}}} will overwrite this old entry (instead of using the newly allocated cache->hbuf), which will later be freed.
