evdns: accept domains up to 254 long (previosly only 63 long was accepted) Previously evdns was using HOST_NAME_MAX, and define it to 255 *only* if it not set, however it does set on linux: $ egrep -r define.*HOST_NAME_MAX /usr/include/bits /usr/include/bits/local_lim.h:#define HOST_NAME_MAX 64 /usr/include/bits/posix1_lim.h:#define _POSIX_HOST_NAME_MAX 255 /usr/include/bits/confname.h:#define _SC_HOST_NAME_MAX _SC_HOST_NAME_MAX But 64 should be the limit of the host component, not for the whole hostname, as also noted by @ploxiln So use our own EVDNS_NAME_MAX const, which is set to 255. Fixes: #1280
