Approved by: jake o Clean up <machine/endian.h> files. o Remove unused __uint16_swap_uint32() from i386's <machine/endian.h>. o Remove prototypes for non-existent bswapXX() functions. o Include <machine/endian.h> in <arpa/inet.h> to define the POSIX-required ntohl() family of functions. o Do similar things to expose the ntohl() family in libstand, <netinet/in.h>, and <sys/param.h>. o Prepend underscores to the ntohl() family to help deal with complexities associated with having MD (asm and inline) versions, and having to prevent exposure of these functions in other headers that happen to make use of endian-specific defines. o Create weak aliases to the canonical function name to help deal with third-party software forgetting to include an appropriate header. o Remove some now unneeded pollution from <sys/types.h>. o Add missing <arpa/inet.h> includes in userland.

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

It is impossible to do this without assembler glue to reset the stack for the new child process. int rfork_thread(flags, stack_addr, start_fnc, start_arg) int flags; Flags to rfork system call. See rfork(2). void *stack_addr; Top of stack for thread. int (*start_fnc)(void *); Address of thread function to call in child. void *start_arg; Argument to pass to the thread function in child. This is deliberately not documented or prototyped in includes until the corresponding alpha version is written.

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

* Simplify sytem call renaming. Instead of _foo() <-- _libc_foo <-- foo(),jasone2000-01-271-6/+7
| | | | | | | | | | | | | | | | | 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

* Creating weak symbols doesn't work correctly when building an aout libc.jasone1999-12-242-8/+4
| | | | | | | | | | | | Doing the "right thing" here is difficult, so create two ENTRY points for each function (for example, __setjmp and setjmp are equivalent). This isn't pretty, but it works for both aout and ELF. libc symbol naming needs an overhaul in order to properly support function wrapping, specifically in the case of a real libpthread, and these duplicate entry points should be fixed as part of that overhaul.

| | | | | | | | __setjmp, __longjmp, __sigsetjmp, and __siglongjmp, respectively. This supports cancellation in the linuxthreads port. In the long run, a much more comprehensive solution will necessitate more dramatic changes to libc symbol naming, and these aliases will probably need modification at that time.

* \begin{quote}marcel1999-10-101-1/+1
| | | | | | | | | | | setjmp() gets the jmp_buf pointer from the wrong place (the place where the return address is) in the shlib case, and uses it (only) to fetch the current signal mask to address (return_address + 28). This address is normally read-only (I hope), so the sigprocmask() call has no effect except to return an error code. \end{quote} Submitted by: bde
