* mpool/mpool_get.c: Avoid clobbering 'errno' when handling 'pread' errorsBojan Novković2026-02-251-0/+4
| | | | | | | | | | | | | | POSIX.1-2024 states that the 'free' function "shall not modify errno if ptr is a null pointer or a pointer previously returned as if by malloc() and not yet deallocated". However this is a fairly recent addition and non-compliant allocators might still clobber 'errno', causing 'mpool_get' to return the wrong error code. Fix this by saving and restoring 'errno' after calling 'free'. Sponsored by: Klara, Inc. Reviewed by: obiwac Differential Revision: https://reviews.freebsd.org/D55463 MFC after: 1 week

* 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. Giffuni2017-11-201-0/+2

* Renumber copyright clause 4Warner Losh2017-02-281-1/+1
| | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | all; before freeing memory, zero out them before we release it as free heap. This will eliminate some potential information leak issue. While there, remove the PURIFY option. There is a slight difference between the new behavior and the old -DPURIFY behavior, with the latter initializes memory with 0xff's.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
* Fix a tailq conversion bug that resulted in, e.g., nvi crashing uponBrian Feldman2000-12-301-1/+2

In any case, the CORRECT way to do it is a loop of TAILQ_EMPTY() checks and TAILQ_REMOVE()al of TAILQ_FIRST(). This bug wouldn't have happened if the loop wasn't hard-coded... There may be more bugs of this type from the conversion. Notes: svn path=/head/; revision=70512

* Simplify sytem call renaming. Instead of _foo() <-- _libc_foo <-- foo(),Jason Evans2000-01-271-3/+3
| | | | | | | | | | | | | | | | | | | | 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.
