* Update the resolver in libc to BIND9's one.ume2006-03-211-26/+43
| | | | | | | | | | | | | | | | | | | | | | 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)
* - Remove padding for ABI compatibility of n_net member from structume2005-06-031-6/+0
| | | | | | | | | | | | | netent. - Change 1st argument of getnetbyaddr() to an uint32_t on 64 bit arch as well to confirm to POSIX-2001. These changes break ABI compatibility on 64 bit arch. There is similar padding issue for ai_addrlen of struct addrinfo. However, it is leaved as is for now. Discussed on: arch@, standards@ and current@ X-MFC after: never
* - The ai_addrlen of a struct addrinfo used to be a size_t, perume2005-05-151-8/+12
| | | | | | | | | | | | | | | | 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. Stay as is on 64 bit arch for ABI backward compatibility for now. Reviewed by: das, peter MFC after: 2 weeks

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | adding (weak definitions to) stubs for some of the pthread functions. If the threads library is linked in, the real pthread functions will pulled in. Use the following convention for system calls wrapped by the threads library: __sys_foo - actual system call _foo - weak definition to __sys_foo foo - weak definition to __sys_foo Change all libc uses of system calls wrapped by the threads library from foo to _foo. In order to define the prototypes for _foo(), we introduce namespace.h and un-namespace.h (suggested by bde). All files that need to reference these system calls, should include namespace.h before any standard includes, then include un-namespace.h after the standard includes and before any local includes. <db.h> is an exception and shouldn't be included in between namespace.h and un-namespace.h namespace.h will define foo to _foo, and un-namespace.h will undefine foo. Try to eliminate some of the recursive calls to MT-safe functions in libc/stdio in preparation for adding a mutex to FILE. We have recursive mutexes, but would like to avoid using them if possible. Remove uneeded includes of <errno.h> from a few files. Add $FreeBSD$ to a few files in order to pass commitprep. Approved by: -arch
