Clean up the vcs ID strings in libc's gen/ directory. - Move CSRG IDs into __SCCSID(). - When a file has been copied, consistently use 'From: <tag>' for strings referencing the version of the source file copied from in the license block comment. - Some of the 'From:' tags were using $FreeBSD$ that was being expanded on each checkout. Fix those to hardcode the FreeBSD tag from the file that was copied at the time of the copy. - When multiple strings are present list them in "chronological" order, so CSRG (__SCCSID) before FreeBSD (__FBSDID). If a file came from OtherBSD and contains a CSRG ID from the OtherBSD file, use the order CSRG -> OtherBSD -> FreeBSD. Reviewed by: imp Differential Revision: https://reviews.freebsd.org/D15831

General further adoption of SPDX licensing ID tags. 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.

popen(): Try to prevent inappropriate fd passing even if 'e' is not used. Even though not all race conditions can be fixed if the 'e' option is not used, still fix some race conditions using pipe2(): * Prevent both ends of the pipe from leaking to a concurrent popen(). * Prevent the child process's end of the pipe from leaking to any concurrent fork and exec. This change also simplifies the code.

popen(): Add 'e' mode character to set close-on-exec on the new fd. If 'e' is used, the kernel must support the recently added pipe2() system call. The use of pipe2() with O_CLOEXEC also fixes race conditions between concurrent popen() calls from different threads, even if the close-on-exec flag on the fd of the returned FILE is later cleared (because popen() closes all file descriptors from earlier popen() calls in the child process). Therefore, this approach should be used in all cases when pipe2() can be assumed present. The old version of popen() rejects "re" and "we" but treats "r+e" like "r+".

Create the altix project branch. The altix project will add support for the SGI Altix 350 to FreeBSD/ia64. The hardware used for porting is a two-module system, consisting of a base compute module and a CPU expansion module. SGI's NUMAFlex architecture can be an excellent platform to test CPU affinity and NUMA-aware features in FreeBSD.

Rename the queue macros I introduced last year. Last year I added SLIST_REMOVE_NEXT and STAILQ_REMOVE_NEXT, to remove entries behind an element in the list, using O(1) time. I recently discovered NetBSD also has a similar macro, called SLIST_REMOVE_AFTER. In my opinion this approach is a lot better: - It doesn't have the unused first argument of the list pointer. I added this, mainly because OpenBSD also had it. - The _AFTER suffix makes a lot more sense, because it is related to SLIST_INSERT_AFTER. _NEXT is only used to iterate through the list. The reason why I want to rename this now, is to make sure we don't release a major version with the badly named macros.

Convert popen()'s `pidlist' to a SLIST, for consistency. I guess the original author of the popen() code didn't want to use our <sys/queue.h> macro's, because the single linked list macro's didn't offer O(1) deletion. Because I introduced SLIST_REMOVE_NEXT() some time ago, we can now use the macro's here. By converting the code to an SLIST, it is more consistent with other parts of the C library and the operating system. Reviewed by: csjp Approved by: philip (mentor, implicit)

Protect pidlist with a mutex to avoid a race causing a duplicate free() when the same pipe FILE is pclosed()'d in different threads, and to avoid corrupting the linked list when adding or removing items. The symptoms of the linked list getting corrupted were pclose() either not finding the pipe on the list, or the list becoming circular and pclose() looping infinitely.

Remove _THREAD_SAFE and make libc thread-safe by default by 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

Simplify sytem call renaming. Instead of _foo() <-- _libc_foo <-- foo(), 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. Suggested by: deischen

vfork -> fork. The child calls execl() which calls malloc(), so vfork() can't be used. We could use alloca() in execl() so that it can be called between vfork() and execve(), but a "portable" popen() shouldn't depend on this. Calling execle() instead of execl() should be fairly safe, since execle() is supposed to be callable from signal handlers and signal handlers can't call malloc(). However, execle() is broken.
