(nscd-modules): Add aicache. * nscd/aicache.c: New file. * nscd/nscd_getai.c: New file. * nscd/cache.c (prune_cache): Handle GETAI request type. * nscd/connections.c: Add GETAI support in request handling. * nscd/nscd-client.h (request_type): Add GETAI. Define ai_response_header and struct nscd_ai_result types. (struct datahead): Add aidata field. Declare __nscd_getai. * nscd/nscd.c: Add getaddrinfo definition to catch problems. * nscd/nscd.h: Declare addhstai and readdhstai. * sysdeps/posix/getaddrinfo.c: Add support for using cached results. * nscd/nscd-client.h (struct datahead): Use uint8_t instead of bool. --- nscd/nscd-client.h | 32 ++++++++++++++++++++++++++++++-- 1 file changed, 30 insertions(+), 2 deletions(-) (limited to 'nscd/nscd-client.h') diff --git a/nscd/nscd-client.h b/nscd/nscd-client.h index 8f3f3a11d7..1a0dd732db 100644 --- a/nscd/nscd-client.h +++ b/nscd/nscd-client.h @@ -61,6 +61,7 @@ typedef enum GETFDPW, GETFDGR, GETFDHST, + GETAI, LASTREQ } request_type; @@ -118,6 +119,28 @@ typedef struct } hst_response_header; +/* Structure sent in reply to addrinfo query.
