+ Don't report 5005 (DIAMETER_AVP_MISSING) errors + unnecessarily.

+

+ An AVP whose decode failed was reported as missing, + despite having been reported with another error as a + consequence of the failure.

+

+ Own Id: OTP-12871

+ + +

+ Fix relay encode of nested, Grouped AVPs.

+

+ A fault in OTP-12475 caused encode to fail if the first + AVP in a Grouped AVP was itself Grouped.

+ Improve decode performance.

+

+ The time required to decode a message increased + quadratically with the number of AVPs in the worst case, + leading to extremely long execution times.

+

+ Own Id: OTP-12891

+ + +

+ Match acceptable peer addresses case insensitively.

+

+ Regular expressions passed in an 'accept' tuple to + diameter_tcp or diameter_sctp inappropriately matched + case.

+

+ Own Id: OTP-12902

+ + +

+ Improve watchdog and statistics performance.

+

+ Inefficient use of timers contributed to poor performance + at high load, as did ordering of the table statistics are + written to.

+

+ Own Id: OTP-12912

+ + +

+ Fix start order of alternate transports.

+

+ A transport configured with diameter:add_transport/2 can + be passed multiple transport_module/transport_config + tuples in order to specify alternate configuration, + modules being attempted in order until one succeeds. This + is primarily for the connecting case; for example, to + allow a transport to be configured to first attempt + connection over SCTP, and then TCP in case SCTP fails. + Multiple module tuples can be paired with a single config + tuple, but in this case the start order was reversed + relative to the order in which the modules were specifed.

+

+ Own Id: OTP-12929

+ + +

+ Fix decode of Grouped AVPs containing errors.

+

+ RFC 6733 says this of Failed-AVP in 7.5:

+

+

In the case where the offending AVP + is embedded within a Grouped AVP, the Failed-AVP MAY + contain the grouped AVP, which in turn contains the + single offending AVP. The same method MAY be employed if + the grouped AVP itself is embedded in yet another grouped + AVP and so on. In this case, the Failed-AVP MAY contain + the grouped AVP hierarchy up to the single offending AVP. + This enables the recipient to detect the location of the + offending AVP when embedded in a + group.

+

+ It says this of DIAMETER_INVALID_AVP_LENGTH in 7.1.5:

+

+

The request contained an AVP with + an invalid length. A Diameter message indicating this + error MUST include the offending AVPs within a Failed-AVP + AVP. In cases where the erroneous AVP length value + exceeds the message length or is less than the minimum + AVP header length, it is sufficient to include the + offending AVP header and a zero filled payload of the + minimum required length for the payloads data type. If + the AVP is a Grouped AVP, the Grouped AVP header with an + empty payload would be sufficient to indicate the + offending AVP. In the case where the offending AVP header + cannot be fully decoded when the AVP length is less than + the minimum AVP header length, it is sufficient to + include an offending AVP header that is formulated by + padding the incomplete AVP header with zero up to the + minimum AVP header length.

+

+ The AVPs placed in the errors field of a diameter_packet + record are intended to be appropriate for inclusion in a + Failed-AVP, but neither of the above paragraphs has been + followed in the Grouped case: the entire faulty AVP + (non-faulty components and all) has been included. This + made it difficult to identify the actual faulty AVP in + all but simple cases.

+

+ The decode is now adapted to the RFC, and implements the + suggested single faulty AVP, nested in as many Grouped + containers as required.
