  • Ticket #560 – Description

    initial v1  
    33With the new approach, each DNS answer cache entry will have it's own pool, and when the answer/entry expires, the pool will be destroyed, thus releasing the memory back to the OS.

     5Also change the pool type used to store the entry. Previously entry uses a fixed size buffer to allocate the memory from, using fixed buffer pool ({{{pool_buf.h}}}. Because of this, entry is created with buffer that must be large enough to parse DNS answer, and if the answer is larger than the buffer size, parsing will fail.

     7This limitation will be gone when we change the pool type to use normal pool instead.
