* General further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-201-0/+2
| | | | | | | | | | | | | | | | | Mainly focus on files that use BSD 3-Clause license. 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. Special thanks to Wind River for providing access to "The Duke of Highlander" tool: an older (2014) run over FreeBSD tree was useful as a starting point. Notes: svn path=/head/; revision=326025

My insistance on keeping the same numbering for legal reasons is too pedantic, so give up on that point.

* libc/i386: Do not export .cerror.Jilles Tjoelker2012-09-051-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | For some reason, libc exports the symbol .cerror (HIDENAME(cerror)), albeit in the FBSDprivate_1.0 version. It looks like there is no reason for this since it is not used from other libraries. Given that it cannot be accessed from C and its strange calling convention, it is rather unlikely that other things rely on it. Perhaps it is from a time when symbols could not be hidden. Not exporting .cerror causes it to be jumped to directly instead of via the PLT. This change also takes advantage of .cerror's new status by not saving and loading %ebx before jumping to it. (Therefore, .cerror now saves and loads %ebx itself.) Where there was a conditional jump to a jump to .cerror, the conditional jump has been changed to jump to .cerror directly (many modern CPUs don't do static prediction and in any case it is not much of a benefit anyway). This change makes libc.so.7 a few kilobytes smaller. Reviewed by: kib Notes: svn path=/head/; revision=240152

* Adjust the syscall stub macros to be consistent in their meaning. InPeter Wemm2007-07-041-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | particular: SYSCALL() makes a syscall, with errno handling, and continues execution directly after the macro in the non-error case. RSYSCALL() is just like SYSCALL(), but returns after success. Both SYSCALL(name) and RSYSCALL(name) export "__sys_name" as a strong symbol, with "_name" and "name" as weak aliases. PSEUDO() is just like RSYSCALL(), but skipping the "name" weak alias. It still does "__sys_name" and "_name". Change i386 to add errno handling to PSEUDO. The same for amd64 and sparc64, with appear to have copied the behavior. ia64 was correct (as was alpha). Just remove some apparently unused variants of the macros. (untested!) I believe powerpc is correct. Fix arm to not export "name" from the PSEUDO case. Remove apparently extra unused variants. (untested!) The errno problem manifested on i386/amd64/sparc64 by having "PSEUDO" classified syscalls return without setting errno. eg: "addr = mmap()" could return with "addr" = 22 instead of setting errno to 22 and returning -1.

* Clean up syscall generation in libc by removing HIDDEN_SYSCALLSDaniel Eischen2001-01-291-31/+6

* Remove _THREAD_SAFE and make libc thread-safe by default byDaniel Eischen2001-01-241-17/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | adding (weak definitions to) stubs for some of the pthread functions. If the threads library is linked in, the real pthread functions will pulled in. Use the following convention for system calls wrapped by the threads library: __sys_foo - actual system call _foo - weak definition to __sys_foo foo - weak definition to __sys_foo Change all libc uses of system calls wrapped by the threads library from foo to _foo. In order to define the prototypes for _foo(), we introduce namespace.h and un-namespace.h (suggested by bde). All files that need to reference these system calls, should include namespace.h before any standard includes, then include un-namespace.h after the standard includes and before any local includes. <db.h> is an exception and shouldn't be included in between namespace.h and un-namespace.h namespace.h will define foo to _foo, and un-namespace.h will undefine foo. Try to eliminate some of the recursive calls to MT-safe functions in libc/stdio in preparation for adding a mutex to FILE. We have recursive mutexes, but would like to avoid using them if possible. Remove uneeded includes of <errno.h> from a few files. Add $FreeBSD$ to a few files in order to pass commitprep. Approved by: -arch Notes: svn path=/head/; revision=71579

* Undo the ill-conceived breakage of the previous commit and really fix:Jason Evans2000-01-291-9/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | For libc_r renamed syscalls, correct symbol naming from _thread_sys_foo() <-- _foo() to _thread_sys_foo() <-- _foo() <-- foo(). This is necessary for system calls which libc_r doesn't define foo(). Some weak symbols such as poll() are defined twice. From what I understand, depending on one weak symbol or the other to be used is a bad idea. All such weak symbols defined in the libc_r-specific code should therefore be made strong (non-weak?). Simplify PSEUDO() to not define any weak symbols, since they aren't ever needed. alpha/SYS.h: Correct reversed usage of WEAK_ALIAS(), which has reversed arguments from __weak_reference(). Also, fix reversal of symbols, so that syscall foo() is a weak alias for _foo(). Add WEAK_ALIAS() call to PRSYSCALL(), which unlike the i386 version of PRSYSCALL(), is not defined in terms of PSYSCALL(). Make PSEUDO() equivalent to the i386 version.

| | | | | | | | | | | | | | | | | | | | just use _foo() <-- foo(). In the case of a libpthread that doesn't do call conversion (such as linuxthreads and our upcoming libpthread), this is adequate. In the case of libc_r, we still need three names, which are now _thread_sys_foo() <-- _foo() <-- foo(). Convert all internal libc usage of: aio_suspend(), close(), fsync(), msync(), nanosleep(), open(), fcntl(), read(), and write() to _foo() instead of foo(). Remove all internal libc usage of: creat(), pause(), sleep(), system(), tcdrain(), wait(), and waitpid(). Make thread cancellation fully POSIX-compliant.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Here are the diffs for libc_r to get it one step closer to P1003.1c These make most of the thread/mutex/condvar structures opaque to the user. There are three functions which have been renamed with _np suffixes because they are extensions to P1003.1c (I did them for JAVA, which needs to suspend/resume threads and also start threads suspended). I've created a new header (pthread_np.h) for the non-POSIX stuff. The egrep tags stuff in /usr/src/lib/libc_r/Makefile that I uncommented doesn't work. I think its best to delete it. I don't think libc_r needs tags anyway, 'cause most of the source is in libc which does have tags. also: Here's the first batch of man pages for the thread functions. The diff to /usr/src/lib/libc_r/Makefile removes some stuff that was inherited from /usr/src/lib/libc/Makefile that should only be done with libc. also: I should have sent this diff with the pthread(3) man page. It allows people to type make -DWANT_LIBC_R world to get libc_r built with the rest of the world. I put this in the pthread(3) man page. The default is still not to build libc_r. also: The diff attached adds a pthread(3) man page to /usr/src/share/man/man3. The idea is that without libc_r installed, this man page will give people enough info to know that they have to build libc_r. Notes: svn path=/head/; revision=17706
* Add support to enable libc to be compiled in ELF format. (#ifdef __ELF__)Peter Wemm1996-05-051-17/+16
| | | | | | | | | | | | | | In a nutshell, this macroizes the local/global symbol scoping rules that are different in a.out and ELF. It also makes the i386 assembler stubs conform to i386 PIC calling conventions - the a.out ld.so didn't object, but the ELF one needs it as it implements PIC jumps via PLT's as well as calls. The a.out rtld only worked because it was accidently snooping the grandparent calling function's return address off the stack.. This also affects the libc_r code a little, because of cpp macro nesting. Notes: svn path=/head/; revision=15634
