* MFH r190382,190416,190525:Hajimu UMEMOTO2009-04-121-90/+197
| | | | | | | | | | | | | | | | | | - getaddrinfo(3) should accept numeric when ai_socktype is not specified in hint or hints is NULL. - Add support for SCTP to getaddrinfo(3). Now, getaddrinfo(3) returns two SOCK_STREAMs, IPPROTO_TCP and IPPROTO_SCTP. It confuses some programs. If getaddrinfo(3) returns IPPROTO_SCTP when SOCK_STREAM is specified by hints.ai_socktype, at least Apache doesn't work. So, I made getaddrinfo(3) to return IPPROTO_SCTP with SOCK_STREAM only when IPPROTO_SCTP is specified explicitly by hints.ai_protocol. - Query DNS only once per an address family.

* Update the resolver in libc to BIND9's one.Hajimu UMEMOTO2006-03-211-75/+83
| | | | | | | | | | | | | | | | | | | | | | | | | Since, res_sendsigned(3) and the friends use MD5 functions, it is hard to include them without having MD5 functions in libc. So, res_sendsigned(3) is not merged into libc. Since, res_update(3) in BIND9 is not binary compatible with our res_update(3), res_update(3) is leaved as is, except some necessary modifications. The res_update(3) and the friends are not essential part of the resolver. They are not defined in resolv.h but defined in res_update.h separately in BIND9. Further, they are not called from our tree. So, I hide them from our resolv.h, but leave them only for binary backward compatibility (perhaps, no one calls them). Since, struct __res_state_ext is not exposed in BIND9, I hide it from our resolv.h. And, global variable _res_ext is removed. It breaks binary backward compatibility. But, since it is not used from outside of our libc, I think it is safe. Reviewed by: arch@ (no objection) Notes: svn path=/head/; revision=156960

| | | | | | | | | | | | | | | | | | | RFC 2553. In XNS5.2, and subsequently in POSIX-2001 and RFC 3493, it was changed to a socklen_t. And, the n_net of a struct netent used to be an unsigned long integer. In XNS5, and subsequently in POSIX-2001, it was changed to an uint32_t. To accomodate for this while preserving ABI compatibility with the old interface, we need to prepend or append 32 bits of padding, depending on the (LP64) architecture's endianness. - Correct 1st argument of getnetbyaddr() to uint32_t on 32 bit arch.

* Make the resolver(3) and many associated interfaces much more reentrant.Brian Feldman2004-02-251-12/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The getaddrinfo(3), getipnodebyname(3) and resolver(3) can coincide now with what should be totally reentrant, and h_errno values will now be preserved correctly, but this does not affect interfaces such as gethostbyname(3) which are still mostly non-reentrant. In all of these relevant functions, the thread-safety has been pushed down as far as it seems possible right now. This means that operations that are selected via nsdispatch(3) (i.e. files, yp, dns) are protected still under global locks that getaddrinfo(3) defines, but where possible the locking is greatly reduced. The most noticeable improvement is that multiple DNS lookups can now be run at the same time, and this shows major improvement in performance of DNS-lookup threaded programs, and solves the "Mozilla tab serialization" problem. No single-threaded applications need to be recompiled. Multi-threaded applications that reference "_res" to change resolver(3) options will need to be recompiled, and ones which reference "h_errno" will also if they desire the correct h_errno values. If the applications already understood that _res and h_errno were not thread-safe and had their own locking, they will see no performance improvement but will not actually break in any way. Please note that when NSS modules are used, or when nsdispatch(3) defaults to adding any lookups of its own to the individual libc _nsdispatch() calls, those MUST be reentrant as well.
