MFC r270802: Only do the second pass over non-plt relocations when the first pass found IFUNCs. Approved by: re (gjb) 2014-08-07T18:36:47Z Mark Johnston markj@FreeBSD.org 2014-08-07T18:36:47Z urn:sha1:9a144e56762b3c60389cccea617146c642d6ffd9 Add a postinit debugger hook to rtld. This will be used by dtrace(1) to halt the victim process before its entry point is called, at which point probes and DOF data are registered with the kernel. The r_debug_state hook cannot be used for this purpose, as it is called before the program's init routines are invoked and in particular before DOF data is registered (via drti.o). 2013-12-13T06:06:08Z Konstantin Belousov kib@FreeBSD.org 2013-12-13T06:06:08Z urn:sha1:10edd290095848624879d9e664293bd6504977cd For variant II static TLS, properly align tls segments.

Instead, a special section .rld_map is used.

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.

No other threads are expected to be running during parsing of the hints and libmap files but the file descriptors need not be passed to child processes so add O_CLOEXEC there as well. This change will break fdlopen() (as used by OpenPAM) on kernels without F_DUPFD_CLOEXEC (added in July). Note that running new userland on old kernels is not supported.
