[S] Change in osmo-mgw[master]: mgcp: fix "L: a:" header parsing: heed ";" separator

by neels

neels has uploaded this change for review. ( https://gerrit.osmocom.org/c/osmo-mgw/+/33534 ) Change subject: mgcp: fix "L: a:" header parsing: heed ";" separator ...................................................................... mgcp: fix "L: a:" header parsing: heed ";" separator In the "L: a:" header, read the first codec name only up to the ";" separator, and ignore the rest. According to RFC-2705, the "L: a:" header may include multiple codecs like "GSM-EFR;GSM" in: L: p:20, a:GSM-EFR;GSM, nt:IN osmo-mgw can handle only a single codec here. Since recently, osmo-msc is our first client that may actually send more than one codec. This uncovered a bug that leads to failing voice calls: * osmo-mgw parses the entire list "GSM-EFR;GSM" as a single codec name, * puts that into the ptmap without scrutiny, * and even sends it back in the OK response, in the *SDP* part, as a single "GSM-EFR;GSM" codec entry. We do not care very much about the "a:" codec list, because we always establish codecs via SDP later. So all we need to fix this is: parse the first codec done correctly, and ignore the rest.
