* getrrsetyname() only uses ERRSET_* and is not supposed to set errno.eric2012-08-182-12/+12

* Improve error reporting in getnameinfo_async() and getaddrinfo_async().eric2012-08-183-57/+46
| | | | | | | | | | They do not have to deal with h_errno at all. Also, errno is only kept for EAI_SYSTEM. Small code cleanup while there. Adapt getnameinfo() and getaddrinfo() wrappers to correctly save errno and overwrite it in the EAI_SYSTEM case. General errno handling issue reported by mikeb@.
* within Rs/Re reference blocks, use %U instead of %O (or any otherjmc2012-08-181-3/+3

* A couple small but long anticipated changes:matthew2012-08-151-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | - Link libpthread.so with -znodlopen. Because libpthread overrides the weak symbols in libc, we can't allow it to be dynamically loaded or else libc's weak symbols might have already been resolved by ld.so. (Also, major bump because this is technically a backwards incompat change in behavior, although dlopen()ing libpthread never really worked.) - Link libc.so with -nodefaultlibs -lgcc. This ensures that libc doesn't try to link against itself (which ld.so wouldn't like). - Change GCC 4 to link shared objects with -lpthread and -lc as appropriate, now that there's no issues with doing so. This means that it's no longer necessary to patch software to use -pthread instead of -lpthread. (Ports tree rejoice!) Also, to preemptively answer this question: No, this does not eliminate the need for LD_PRELOAD=libpthread.so. That's a separate issue that won't be resolved until we eliminate libc's weak symbols. Discussed extensively on email and icb over the past few months. ok deraadt

* Fix almost ten-years old bug in siglongjmp(), which would not restore a signalmiod2012-08-123-87/+57
| | | | | | | | | | | | | mask of zero (because of flawed logic assuming finding zero in the sigjmp_buf signal mask means sigsetjmp was invoked with a zero `savemask' argument). While there, clean comments of all *{set,long}jmp routines, and shave a few instructions by using bcnd insead of cmp + bb to test for zero values. Passes the regress tests, and now devel/libsigsegv configure siglongjmp test will not spin (this test is however flawed as it expects a signal handler declared as running on the sigaltstack and `returning' through siglongjmp to be invoked on the signal stack the next time the signal is raised).

* Use nl_langinfo(RADIXCHAR) instead of localeconv()->decimal_point inmatthew2012-06-262-4/+10
| | | | | | | | | | | | | | | | printf() and avoid calling it unless needed (i.e., when we have a floating point value to print). This isn't a big concern currently due to our limited locale support and current localeconv() implementation, but it's still technically a data race and implementing POSIX 2008 per-thread locales is likely to make it worse. nl_langinfo() isn't guaranteed by POSIX to be thread-safe either, but at least our current implementation is thread-safe and it's a simpler interface to keep that way. Printing floating point values isn't async-signal-safe anyway due to gdtoa()'s use of malloc(), so that's not an issue. ok deraadt, stsp, millert

Simplifies the code and makes it the same on both ILP32 and LP64 architectures, and also slightly faster on LP64 architectures by using a 32-bit remainder instead of a 64-bit remainder.
