*Note: Please adhere to [Contributing Guidelines](https://github.com/apache/nuttx/blob/master/CONTRIBUTING.md).* ## Summary `timer_gethandle()` accepted any allocated timer in the system, so a process could set, read or delete another process's timer by its handle. Accept a handle only from a thread of the owner's process. The expiry callback runs in interrupt context, where the current task is unrelated, and is exempt. ## Impact Every build with POSIX timers. `timer_settime()`, `timer_gettime()`, `timer_getoverrun()` and `timer_delete()` on another process's timer now fail with `EINVAL`. Threads of the owning process are unaffected. ## Testing Host: Ubuntu 24.04, x86_64. Builds and runs in `ghcr.io/apache/nuttx/apache-nuttx-ci-linux` (QEMU 6.2, Arm GNU GCC 13.2). | Where | Result | | --- | --- | | `sim:nsh`, a task (separate process) using its parent's timer | master: reads and deletes it; this PR: `EINVAL`, the owner keeps it | | `qemu-armv8a:knsh` | `ostest` passes, its POSIX timer test included; `hello` | | `sim:ostest`, `qemu-armv7a:knsh` | build | `tools/checkpatch.sh -c -u -m -g` clean. <details><summary><code>sim:nsh</code>: another process's timer, master then this PR</summary> ``` == master (c046c337) timerx: owner timer_gettime: 0 timerx: other process timer_gettime: 0 errno 0 timerx: other process timer_delete: 0 errno 0 timerx: owner timer_gettime after: -1 errno 22 == this PR timerx: owner timer_gettime: 0 timerx: other process timer_gettime: -1 errno 22 timerx: other process timer_delete: -1 errno 22 timerx: owner timer_gettime after: 0 errno 0 ``` The test, as `examples/hello`: ```c #include <nuttx/config.h> #include <errno.h> #include <sched.h> #include <signal.h> #include <stdio.h> #include <time.h> #include <unistd.h> static timer_t g_timer; static int other_process(int argc, char *argv[]) { struct itimerspec its; int ret = timer_gettime(g_timer, &its); printf("timerx: other process timer_gettime: %d errno %d\n", ret, ret < 0 ?
