syscall: clock_systimer() is no longer a system call. It has been replaced with the equivalent, standard interface clock() as the system call. sched/clock: Move the implementation of clock() from libs/libc/time to sched/clock. This is necessary because it calls the (now) internal OS function clock_systimer. clock() is now accessed only via a system call in certain configuratins. libs/libc/wqueue: Replace calls to clock_systimer() with calls to the equivalent clock().

syscall/ and include/sys/syscall.h: Fix an inconsistency. In someplaces, getitimer() and setitimer() depend on CONFIG_DISABLE_POSIX_TIMERS=n and in other places they depend on nothing. As a result, there are link failures when CONFIG_DISABLE_POSIX_TIMERS=y. Which is correct? On one hand, these interfaces are not POSIX timers, so conditioning them on on CONFIG_DISABLE_POSIX_TIMERS. I opted to keep the dependence and just apply it consistently. I did this because setitimer() and getitimer() are seldom used so it is really best if a system call is no generated for them in all cases.

sched/signal: Add support for disabling all signal functions Signals in NuttX serve two primary purposes: 1. Synchronization and wake-up: Signals can be used to block threads on specific signal sets and later wake them up by delivering the corresponding signals to those threads. 2. Asynchronous notification: Signals can also be used to install callback handlers for specific signals, allowing threads to asynchronously invoke those handlers when the signals are delivered. This change introduces the ability to disable all signal functionality to reduce footprint for NuttX. Signed-off-by: Chengdong Wang wangchengdong@lixiang.com

move readv/writev to the kernel currently, nuttx implements readv/writev on the top of read/write. while it might work for the simplest cases, it's broken by design. for example, it's impossible to make it work correctly for files which need to preserve data boundaries without allocating a single contiguous buffer. (udp socket, some character devices, etc) this change is a start of the migration to a better design. that is, implement read/write on the top of readv/writev. to avoid a single huge change, following things will NOT be done in this commit: * fix actual bugs caused by the original readv-based-on-read design. (cf. https://github.com/apache/nuttx/pull/12674) * adapt filesystems/drivers to actually benefit from the new interface. (except a few trivial examples) * eventually retire the old interface. * retire read/write syscalls. implement them in libc instead. * pread/pwrite/preadv/pwritev (except the introduction of struct uio, which is a preparation to back these variations with the new interface.)

sched/signal: Add support for partially disabling signals Signals in NuttX serve two primary purposes: 1. Synchronization and wake-up: Signals can be used to block threads on specific signal sets and later wake them up by delivering the corresponding signals to those threads. 2. Asynchronous notification: Signals can also be used to install callback handlers for specific signals, allowing threads to asynchronously invoke those handlers when the signals are delivered. This change introduces the ability to partially disable signal functionality: to disable only signal functions for Asynchronous notification, keeping functions for Synchronization and wake-up. This enables finer-grained control over signal usage while preserving existing behavior for supported use cases.

As a result, there are link failures when CONFIG_DISABLE_POSIX_TIMERS=y. Which is correct? On one hand, these interfaces are not POSIX timers, so conditioning them on on CONFIG_DISABLE_POSIX_TIMERS. I opted to keep the dependence and just apply it consistently. I did this because setitimer() and getitimer() are seldom used so it is really best if a system call is no generated for them in all cases.

!sched/arch/libc: Give fork() and vfork() their real, separate semantics. NuttX implemented fork() and vfork() as the same function. Both were libc wrappers around a single up_fork() syscall; vfork() differed only by a trailing waitpid(). Underneath, the child joined the parent's address environment -- the same addrenv_join() that pthread_create() uses -- and got a private copy of the stack. So the child shared .data, .bss and the heap with its parent and ran concurrently with it. That is not fork(). It is vfork()-with-a-private-stack under fork()'s name, and the history says so: today's fork() is NuttX's old vfork(), renamed in c33d1c9c97 (2023) without any change of behaviour. The failure was silent -- a program written against POSIX fork() compiled, ran, and had its child's writes land in the parent's variables. Separate them into two primitives, chosen by which function the caller called rather than by what the hardware happens to be: fork() child gets its own copy of the parent's memory at the same virtual addresses; runs concurrently. Only where an address environment can be duplicated -- elsewhere it is not declared at all, so calling it is a build error naming the function. vfork() child shares the parent's memory; parent suspended until the child _exit()s or exec()s. Implementable everywhere. Below libc there is still one syscall. up_fork() gains a bool saying which primitive the caller used, since the per-architecture register snapshot is the same for both, and passes it to nxtask_setup_fork(), which is the single place the memory semantics are decided. The argument arrives in the first argument register and is never touched: each architecture's snapshot takes some other call-clobbered register for its scratch, so the flag is simply still there when the C worker is called. The vfork() parent suspension moves out of libc into nxtask_start_fork(), released from nxsched_release_tcb() by nxtask_resume_vfork(). Two things follow: the parent is resumed at exec(), since exec_swap() has already handed the child's pid to the loaded program by the time the vfork stub exits, and vfork() no longer depends on CONFIG_SCHED_WAITPID. Releasing there requires one fix in nxtask_exit(). It raises rtcb->lockcount directly rather than through sched_lock() while it tears the TCB down, so the nxsem_post() that wakes the vfork() parent leaves it queued where a blocked task collects while pre-emption is off -- g_pendingtasks, or g_readytorun on SMP -- and the matching raw lockcount-- does not publish it the way sched_unlock() would, leaving the parent stranded with nothing to move it on. The fix mirrors sched_unlock() for each case: nxsched_merge_pending(), or nxsched_deliver_task() under CONFIG_SMP. Both are no-ops while pre-emption is still disabled, and up_exit() re-reads this_task() afterwards, so a change of the ready-to-run head is honoured. Without it vfork() deadlocks wherever no other task happens to call sched_unlock() afterwards -- rv-virt:nsh64 and rv-virt:pnsh64, where NSH is blocked in waitpid() holding the lock, and qemu-armv8a:citest_smp, which hangs the moment the vfork() test runs. fork() is built on a new addrenv_fork(), backed by an up_addrenv_fork() hook that duplicates an address environment into freshly allocated pages mapped at the same virtual addresses -- unlike up_addrenv_clone(), which copies only the representation and leaves both pointing at the same page tables. The child then adopts the parent's stack geometry rather than being given a relocated copy: a pointer to a stack local taken before fork() must name the same object in the child that it named in the parent, and the parent's stack is already in the duplicate, with its contents, at the parent's address. No architecture implements up_addrenv_fork() yet, so this commit leaves fork() unavailable everywhere. That is the intended state. It withdraws fork() from ARCH_ARM, flat ARCH_ARM64, ARCH_RISCV, ARCH_SIM and ARCH_X86_64, where until now it named the sharing primitive; per-architecture patches restore it, with POSIX semantics, as up_addrenv_fork() lands. In the meantime the sharing primitive is still there under the name that describes it: vfork() for a child that runs a program, pthread_create() for a second flow of control that shares memory, posix_spawn() for both at once. Kconfig: ARCH_HAVE_VFORK inherits ARCH_HAVE_FORK's select lines, conditions included, so no configuration gains machinery; ARCH_HAVE_FORK is redefined to mean "can provide POSIX fork() semantics" and now depends on ARCH_ADDRENV. There is one deliberate departure from "verbatim". ARCH_ARM selected the fork family unconditionally, BUILD_KERNEL included, and that has never worked: on a kernel build the architecture's fork entry point sees the kernel's return address and stack pointer rather than the caller's, so the child resumes at a kernel address. On qemu-armv7a:knsh master faults in ostest's fork case with "Child did not run" and then a data abort; without the condition this change faults the same way through vfork(). ARCH_ARM64 and ARCH_X86_64 already carried "if !BUILD_KERNEL" for exactly this reason -- ARM was the outlier. Conditioning it turns a runtime fault into an honest absence, which is the whole point of the change; arch/arm takes the condition off again in the patch that adds its saved-syscall-frame path. Only the MMU-capable ARM ports are affected, since Cortex-M cannot build BUILD_KERNEL at all. Also fixes two latent syntax errors found on the way: a missing comma in riscv_fork.c and mips_fork.c, both in *_FRAMEPOINTER && !SAVE_GP branches that are never compiled today. BREAKING CHANGE: fork() is withdrawn from every architecture. It is no longer declared in unistd.h, so code that calls it fails to build with an error naming the function, and the sharing behaviour it used to have is gone rather than renamed. CONFIG_ARCH_HAVE_FORK no longer means "fork() exists"; it means "this configuration can provide POSIX fork() semantics", and no architecture selects it yet. Quick fix, chosen by why the call was made: to run a program vfork() + exec*(), or better posix_spawn() a second flow of control that pthread_create() shares the caller's memory a genuinely independent copy keep fork(), and wait for the per-arch patch of the process that implements up_addrenv_fork() and selects CONFIG_ARCH_HAVE_FORK Out-of-tree code that tests CONFIG_ARCH_HAVE_FORK to decide whether a fork-then-exec path is available wants CONFIG_ARCH_HAVE_VFORK instead, which is selected in exactly the places CONFIG_ARCH_HAVE_FORK used to be.

move readv/writev to the kernel currently, nuttx implements readv/writev on the top of read/write. while it might work for the simplest cases, it's broken by design. for example, it's impossible to make it work correctly for files which need to preserve data boundaries without allocating a single contiguous buffer. (udp socket, some character devices, etc) this change is a start of the migration to a better design. that is, implement read/write on the top of readv/writev. to avoid a single huge change, following things will NOT be done in this commit: * fix actual bugs caused by the original readv-based-on-read design. (cf. https://github.com/apache/nuttx/pull/12674) * adapt filesystems/drivers to actually benefit from the new interface. (except a few trivial examples) * eventually retire the old interface. * retire read/write syscalls. implement them in libc instead. * pread/pwrite/preadv/pwritev (except the introduction of struct uio, which is a preparation to back these variations with the new interface.)
