MFC r304012: Fill phdr and phsize for rtld object.

Approved by: re (gjb) 2016-05-25T18:10:44Z Konstantin Belousov kib@FreeBSD.org 2016-05-25T18:10:44Z urn:sha1:360ba6bc13d1d194f1b3a345d4afc150aba0c6ae Check that the dirlist path string specification does not cause overflow and is fully contained in the hints file. Check that the dirlist string is nul-terminated. Make 'hdr' static variable, so that hdr.dirlistlen is available when hints cached value is used on next function calls. Reset hdr.dirlistlen to zero if error was detected, so that allocations use reasonable size. Use 'hints', and not 'p' in the body, since p is only initialized on the first call.

According to gABI spec, presence of the tag indicates that dynamic linker must be prepared to handle relocations against any read-only segment, not only the segment which we, somewhat arbitrary, declared the text. For each read-only segment, add write permission before relocs are processed, and return to the mapping mode requested by the phdr, after relocs are done.

This was fixed once already in r178807, but accidentally got reverted in r294373. 2016-01-20T23:26:35Z Alexander Kabaev kan@FreeBSD.org 2016-01-20T23:26:35Z urn:sha1:832b9473057a675a90b4b1e7929ef3c5b82904f6 The tail parameter should point to the last object for which dependencies should be processed. In most cases, this is the object itself. 2016-01-20T07:21:33Z Konstantin Belousov kib@FreeBSD.org 2016-01-20T07:21:33Z urn:sha1:9fee0541f2815c1ea70ccc13402f3ed6c4ed9fdf phdr locks locked. This allows to call rtld services from the callback, which is only reasonable for dlopen(path, RTLD_NOLOAD) to test existence of the library in the image, and for dlsym(). The later might still be not quite safe, due to the lazy resolution of filters. To allow dropping the locks around iteration in dl_iterate_phdr(3), we insert markers to track current position between relocks. The global objects list is converted to tailq and all iterators skip markers, globallist_next() and globallist_curr() helpers are added.

When we've fully transitioned, it will make no sense to do this stat, and it will be removed.
