* When building picobsd, define WITHOUT_OPENSSL and WITHOUT_KERBEROS andimp2014-06-061-3/+0
| | | | | | | | | remove the now-redundant checks for RELEASE_CRUNCH. This originally was defined for building smaller sysinstall images, but was later also used by picobsd builds for a similar purpose. Now that we've moved away from sysinstall, picobsd is the only remaining consumer of this interface. Adding these two options reduces the RELEASE_CRUNCH special cases in the tree by half.
* Change libatf-c and libatf-c++ to be private libraries.jmmv2014-05-251-2/+2
| | | | | | | | | | | | | | We should not be leaking these interfaces to the outside world given that it's much easier for third-party components to use the devel/atf package from ports. As a side-effect, we can also drop the ATF pkgconfig and aclocal files from the base system. Nothing in the base system needs these, and it was quite ugly to have to get them installed only so that a few ports could build. The offending ports have been fixed to depend on devel/atf explicitly. Reviewed by: bapt
* Right now, the rtld prefork hook locks the rtld bind lock in the readkib2014-05-241-1/+15
| | | | | | | | | | | | | | | | | | mode. This allows the binder to be functional in the child after the fork (assuming no lazy loading of a filter is needed), but other rtld services which require write lock on rtld_bind_lock cause deadlock, if called by child. Change the _rtld_atfork() to lock the bind lock in write mode, making the rtld fully functional after the fork. Pre-resolve the symbols which are called by the libthr' fork() interposer, since dynamic resolution causes deadlock due to the rtld_bind_lock already owned in the write mode.

* Before calling mmap() on a shared library's text and data sections, rtldalc2014-04-114-25/+67
| | | | | | | | | | | | | | | | | | | | | | | | | | first calls mmap() with the arguments PROT_NONE and MAP_ANON to reserve a single, contiguous range of virtual addresses for the entire shared library. Later, rtld calls mmap() with the the shared library's file descriptor and the argument MAP_FIXED to place the text and data sections within the reserved range. The rationale for mapping shared libraries in this way is explained in the commit message for Revision 190885. However, this approach does have an unintended, negative consequence. Since the first call to mmap() specifies MAP_ANON and not the shared library's file descriptor, the kernel has no idea what alignment the vm object backing the file prefers. As a result, the reserved range's alignment is unlikely to be the same as the vm object's, and so mapping with superpages becomes impossible. To address this problem, this revision adds the argument MAP_ALIGNED_SUPER to the first call to mmap() if the text section is larger than the smallest superpage size. To determine if the text section is larger than the smallest superpage size, rtld must always fetch the page size information. As a result, the private code for fetching the base page size in rtld's builtin malloc is redundant. Eliminate it.

* Make bsd.test.mk the only public mk fragment for the building of tests.jmmv2014-03-141-1/+1
| | | | | | | | | | | | | | Change {atf,plain,tap}.test.mk to be internal implementation details of bsd.test.mk. Makefiles that build tests should now only include bsd.test.mk and declaratively specify what they want to build, without worrying about the internal implementation of the mk files. The reason for this change is to permit building test programs of different interfaces from a single directory, which is something I had a need for while porting tests over from src/tools/regression/. Additionally, this change makes it possible to perform some other requested changes to bsd.test.mk in an easier manner. Coming soon.

This is wrong, because origin_subst_one() performs the substitution on the whole rpath and similar strings, which contain several pathes separated by colon. As result, long (but correct) rpath consisting of many path elements is rejected by the function. Correct the problem by rewriting the origin_subst_one() to perform two passes, first pass to calculate the number of substitutions to be performed, and second pass to generate the resulting string. Second pass allocates the memory for the result based on the count from the first pass, without enforcing a limit. Reported and tested by: pgj Sponsored by: The FreeBSD Foundation MFC after: 2 weeks
