commit 1e50e2ad4813c037b0fbc5559381ec22776225d7
Author: Stefan Sperling <ssperling at sysmocom.de>
Date:   Mon Jan 8 19:20:02 2018 +0100

    TLVP_PRESENT() should not return TRUE after tlv_parse() fails.
    
    If the length provided in the patcket exceeds the buffer length,
    tlv_parse() returns -2 but leaves tlv.val and tlv.len initializd.
    
    Many callers of tlv_parse() do not check its return value, but
    rely on TLVP_PRESENT() to see if a particular TLV was parsed
    successfully. By clearing tlv.val and tlv.len we make it less
    likely that those callers will use an overlong TLV length value.
