* Remove the SYMVER build option.John Baldwin2020-04-301-4/+2
| | | | | | | | | | | | | | This option was added as a transition aide when symbol versioning was first added. It was enabled by default in 2007 and is supported even by the old GPLv2 binutils. Trying to disable it currently fails to build in libc and at this point it isn't worth fixing the build.

* libc: further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-251-0/+2
| | | | | | | | | | | | | | | Mainly focus on files that use BSD 2-Clause license, however the tool I was using mis-identified 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. Notes: svn path=/head/; revision=326193
* General further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-2046-0/+92

* Renumber copyright clause 4Warner Losh2017-02-2851-51/+51
| | | | | | | | | | | | Renumber cluase 4 to 3, per what everybody else did when BSD granted them permission to remove clause 3. My insistance on keeping the same numbering for legal reasons is too pedantic, so give up on that point.

* Switch libc from using _sig{procmask,action,suspend} symbols, whichKonstantin Belousov2015-08-292-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | are aliases for the syscall stubs and are plt-interposed, to the libc-private aliases of internally interposed sigprocmask() etc. Since e.g. _sigaction is not interposed by libthr, calling signal() removes thr_sighandler() from the handler slot etc. The result was breaking signal semantic and rtld locking. The added __libc_sigprocmask and other symbols are hidden, they are not exported and cannot be called through PLT. The setjmp/longjmp functions for x86 were changed to use direct calls, and since PIC_PROLOGUE only needed for functional PLT indirection on i386, it is removed as well. The PowerPC bug of calling the syscall directly in the setjmp/longjmp implementation is kept as is.

| | | | | | | | | | | | | | | | This fix mostly matters after r206129 that made it possible for st_blksize to be greater than 4K. For this reason, this change should be MFC-ed before r206129. Also, it seems that all FreeBSD uitlities that use db(3) hash databases and create new databases in files, specify their own block size value and thus do not depend on block size autotuning.
