[lwip-devel] [bug #48359] dns entries are not set to state DONE

[Douglas]

Follow-up Comment #2, bug #48359 (project lwip):

Have seen a problem with the 1.4.1 code after setting the state to DONE and
then calling the 'found' callback. If this callback re-enters the dns code
then dns_equeue might reuse the entry but after the return from this callback
the state might be set to UNUSED. It is not clear if this could happen in the
current code but it seems possible?
