* ldconfig: remove ignored -v (verbose) optionStefan Eßer2024-03-011-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | The -v option used to print useful information when operating on a.out format libraries. After the removal of a.out support, it was accepted but did not have any effect. Remove the option and update the man-page. While here mention the set of historic options that are accepted but ignored: "-elf", "-s", and "-v". The FILES section contained outdated information and did not mention the way library directories of optional ports and packages are included in the library search path recorded in the hints file. The description of the "-B" option was incorrect (described a planned change) for big-endian platforms (powerpc64). These do still default to big-endian hints files, since the current version of the "pkg" program expects the hints file to be in native byte-order.

* ldconfig: support hints files of either byte-orderStefan Eßer2024-02-281-5/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make the ldconfig program accept hints files in little-endian and big-endian format on all architectures. The default format is the native byte-order of the respective host. This is expected to change when a version of the pkg command is available that implements support for either byte-order in its internal ldconfig function. (Already committed in the development tree of the pkg utility, a release is expected at the end of Q1/2024). This update adds the -B option to the ldconfig program. It enforces the creation of a big-endian hints file on a little-endian host. The main purpose to is support of tests with non-native byte-order files on little-endian hosts. It will be removed when all supported FreeBSD releases use little-endian hints files by default. When little-endian hints files are generally used, support of either byte-order in libexec/rtld can also be removed. When support for big-endian hints files is no longer required, the COND_SWAP macro in ldconfig and rtld shall be replaced by le32toh(), which just return their argument on little-endian architectures.

* ldconfig(8): check for no-args command line after options are parsedKonstantin Belousov2021-11-241-5/+6
| | | | | | | | | | | | | | | | | | | Default action for ldconfig is specified as -R AKA 'append', and for no-args (without options changing default actions), ldconfig should append empty list of directories to current list. But because the check was done before options were parsed out, presence of any option turned off default rescan. As result, innocently-looked commands like `ldconfig -v' were interpreted as setting directory hints list to one specified on the command line, i.e. empty.

| | | | | | | | | | | | | | | | | 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.

* Implement ldconfig functionality for ELF. The hints are stored inJohn Polstra1998-09-051-9/+92
| | | | | | | | | | | | | | | | | | | | | | | | | | a different file than the a.out hints, namely, "/var/run/ld-elf.so.hints". These hints consist only of the directory search path. There is no hash table as in the a.out hints, because ELF doesn't have to search for the file with the highest minor version number. (It doesn't have minor version numbers at all.) A single run of ldconfig updates either the a.out hints or the ELF hints, but not both. The set of hints to process is selected in the usual way, via /etc/objformat, or ${OBJFORMAT}, or the "-aout" or "-elf" command line option. The rationale is that you probably want to search different directories for ELF than for a.out. "ldconfig -r" is faked up to produce output like we are used to, except that for ELF there are no minor version numbers. This should enable "ldconfig -r" to be used for checking LIB_DEPENDS in ports even for ELF. I implemented the ELF functionality in a new source file, with an eye toward eliminating the a.out code entirely at some point in the future. Notes: svn path=/head/; revision=38836

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

This is an ideal way of updating the hints list after adding or removing a shlib since it will remove entries that are gone and doesn't need to have all the directories spelled out each time. (eg: rm -f /usr/lib/libtcl75*; ldconfig -R) This only works for version 2 hints files (which we've been generating for a year or so) which store the path. Notes: svn path=/head/; revision=28559
