* libexec: adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-274-3/+11
| | | | | | | | | | | | | | | | | Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. No functional change intended.

* 64-bit clean + WARNS=6:Xin LI2005-01-142-5/+4
| | | | | | | | | | | | | | | | | | | | - Convert the (char *) cast+cast backs magic to memcpy(3). Without this, the resulting code is potentially risky with higher optimization levels. - Avoid same name when calling local variables, as well as global symbols. This reduces confusion for both human and compiler. - Add necessary casts, consts - Use new style function defination. - Minor style.Makefile(5) tweak - Bump WARNS?= from 0 to 6 ** for the aout code: changes are intentionally limited to ease maintaince.

* Fix a bug in the handling of minor version numbers. Formerly, theJohn Polstra1998-11-071-13/+34
| | | | | | | | | | | | | | | | | | | rtld would accept the first shared library it found with the right major version number, even if the minor version number was too low. If a different version of the shared library with an adequate minor version number appeared later in the search path, it would not be found. Now the rtld searches all locations first looking for a library with a minor version that is high enough. Only if such a library is not found will it fall back to accepting a minor version number that is too low. As before, a warning comes out in that case. This solves some problems encountered when building an older world on a -current system. Notes: svn path=/head/; revision=40983
* Don't recognize a file as an a.out shared library unless it has atJohn Polstra1998-09-051-6/+4
| | | | | | | | | | | | | | | least 2 version numbers. This fixes the bug where the dynamic linker would try to load an ELF shared library if it found one. Note, this change also fixes the same thing in "ld", because the code is shared. For "ld" there is still a problem with ".a" libraries, which cannot be distinguished by name. I haven't decided what, if anything, to do about that. Notes: svn path=/head/; revision=38870

| | | | | | | | | | | | | | | alternative, I present .. ta! da! .. the __error() hack. This patch to the a.out dynamic loader provides old a.out binaries with __error() if they are linked with an older libc that lacks it, but are also linked against a library that needs it. There is a smaller, tricker hack that takes advantage of the fact that ld.so has __error() too, courtesy of the new libc, but this hack is the straightforward version.

Make ldconfig reject /usr/lib as an a.out library path. Fix various Makefiles for LIBDIR!=/usr/lib breakage. This will after a make world & reboot give a system that no longer uses /usr/lib/*, infact one could remove all the old libraries there, they are not used anymore. We are getting close to an ELF make world, but I'll let this all settle for a week or two... Notes: svn path=/head/; revision=36397

| | | | | | | | | | | | | | | | | | | | | | | emacs a.out file, self-generated by emacs's "unexec" function in "unexsunos4.c", is invalid. In particular, its "_end" symbol has the wrong value. The dynamic linker was using the value of that symbol to initialize its sbrk break level. The workaround is to peek at the executable's a.out header in memory, and calculate what "_end" should be based on the segment sizes. I will work out a fix for emacs and send it to the FSF. This dynamic linker workaround is still worthwhile, if only to avoid forcing all emacs users to build a new version. Note: xemacs gives a bogus warning at startup, for related reasons. The warning is harmless and can safely be ignored. I will send a patch to the xemacs maintainers to get rid of it, and meanwhile add a patch file to our port. Notes: svn path=/head/; revision=31546
* Get rid of the dynamic linker's internal malloc package, and arrangeJohn Polstra1997-11-292-267/+474
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | things so that it uses the same malloc as is used by the program being executed. This has several advantages, the big one being that you can now debug core dumps from dynamically linked programs and get useful information out of them. Until now, that didn't work. The internal malloc package placed the tables describing the loaded shared libraries in a mapped region of high memory that was not written to core files. Thus the debugger had no way of determining what was loaded where in memory. Now that the dynamic linker uses the application's malloc package (normally, but not necessarily, the system malloc), its tables end up in the regular heap area where they will be included in core dumps. The debugger now works very well indeed, thank you very much. Also ... Bring the program a little closer to conformance with style(9). There is still a long way to go. Add minimal const correctness changes to get rid of compiler warnings caused by the recent const changes in <dlfcn.h> and <link.h>. Improve performance by eliminating redundant calculations of symbols' hash values. Notes: svn path=/head/; revision=31445

| | | | | | | | | | | | | | ld-specific flags. LDFLAGS is really for ld-related flags for cc, not for ld, and some flags, e.g., -Bshareable, mean completely different things to cc and ld. Having the wrong things in LDFLAGS also broke the standard ${PROG} target. This was kludged around by using a special rule that depended on LDFLAGS being bogus. Fixing `make depend' broke the special rule but fixed the standard rule (except in the DESTDIR case, which was handled more strictly here than elsewhere). Notes: svn path=/head/; revision=24979
