[BZ #20593]
|
||||
Update DNS RR type definitions.

||||
* scripts/gen-rrtypes.py: New file.
|
||||
* resolv/arpa/nameser.h (ns_type): Remove ns_t_zxfr, a
|
||||
BIND-internal RR type not used on the Internet. Add ns_t_ds,
|
||||
ns_t_sshfp, ns_t_ipseckey, ns_t_rrsig, ns_t_nsec, ns_t_dnskey,
|
||||
ns_t_dhcid, ns_t_nsec3, ns_t_nsec3param, ns_t_tlsa, ns_t_smimea,
|
||||
ns_t_hip, ns_t_ninfo, ns_t_rkey, ns_t_talink, ns_t_cds,
|

ns_t_cdnskey, ns_t_openpgpkey, ns_t_csync, ns_t_spf, ns_t_uinfo,
|
||||
ns_t_uid, ns_t_gid, ns_t_unspec, ns_t_nid, ns_t_l32, ns_t_l64,
|
||||
ns_t_lp, ns_t_eui48, ns_t_eui64, ns_t_uri, ns_t_caa, ns_t_avc,
|
||||
ns_t_ta, ns_t_dlv.
|
||||
* resolv/arpa/nameser_compat.h (T_KX, T_CERT, T_SINK, T_OPT)
|
||||
(T_APL, T_DS, T_SSHFP, T_IPSECKEY, T_RRSIG, T_NSEC, T_DNSKEY)
|

(T_DHCID, T_NSEC3, T_NSEC3PARAM, T_TLSA, T_SMIMEA, T_HIP, T_NINFO)

|
||||
(T_EUI48, T_EUI64, T_TKEY, T_URI, T_CAA, T_AVC, T_TA, T_DLV):
|
||||
Define.
|

"""Generate DNS RR type constants for resolv header files.
|
||||
|
||||
resolv/arpa/nameser.h and resolv/arpa/nameser_compat.h contain lists
|
||||
of RR type constants. This script downloads the current definitions
|
||||
from the IANA DNS Parameters protocol registry and translates it into
|
||||
the two different lists.
|
||||
|
||||
Two lists are written to standard output. The first one contains enum
|
||||
constants for resolv/arpa/nameser.h. The second one lists the
|
||||
preprocessor macros for resolv/arpa/nameser_compat.h.
