The dns_catz_generate_zonecfg() function generates a zone configuration string to use with a new catalog zone member zone. The buffer for the string is 512 bytes initially (ISC_BUFFER_INCR), but can be reallocated when required, when using corresponding isc_buffer functions like isc_buffer_reserve(), isc_buffer_putstr(), isc_buffer_copyregion(), etc. However, the dns_name_totext() function, which expects the buffer as an argument, doesn't automatically resize it if the name doesn't fit there, but instead just returns ISC_R_NOSPACE. The chance of this occurring increases when the configuration string is large due to, for example, long zone name, long list of primary servers which have keys configured and/or TLS configured. Use dns_name_format() accompanied with isc_buffer_putstr() instead of dns_name_totext(). |
