8fe8417ffb libc/fdcheck: add fdcheck module
In embedded development environments, due to the lack of address isolation between processes,
fd may be passed between processes and lead to misuse,

We have designed an fd cross-process automatic detection tool,
fdcheck_protect returns the fd containing the pid information,
indicating that the ownership of the current fd belongs to the pid and is not allowed to be used by other processes.
fdcheck_restore will obtain the true fd and check if the ownership of the fd is legal

For ease of understanding, let's give an example where
the following information is represented in 32-bit binary format

fd        00000000 00000000 00000000 10001010
pid       00000000 00000000 00000011 01010101
ret       00000000 00000011 01010101 10001010

441b51b706 libc/regex: provide a separate kconfig for regex
in the initial impl, the regex is depends on ALLOW_MIT_COMPONENTS, and
if other modules want to use regex, also needs to depends on
ALLOW_MIT_COMPONENTS, which is ambiguity, so we provide a seperate
kconfig option for regex: LIBC_REGEX, which is depends on
ALLOW_MIT_COMPONENTS, but is enabled by default. Thus if
ALLOW_MIT_COMPONENTS is enabled, then the LIBC_REGEX is also enabled
either automatically, and this is more clear than controlled by
ALLOW_MIT_COMPONENTS option only.

58e97e521c libc/string: prevent libc in the kernel/userspace optionally
Add the `LIBC_PREVENT_STRING_KERNEL` and `LIBC_PREVENT_STRING_USER`
that are meant to be selected by the chip if no libc implementation
is going to be built. If selected, neither NuttX's software version
of the libc nor any architecture-specific implementation will be
built in the kernel or in the userspace, respectively. In this
case, the linker may provide a ROM-defined version of the libc
functions instead.

90387a5b41 libc/misc: add fdsan module
FD (file descriptor) is widely used in system software development,
and almost all implementations of posix os (including nuttx) use FD as an index.
the value of fd needs to be allocated starting from the minimum available value of 3, and each process has a copy,
so the same fd value is very easy to reuse in the program.

In multi threaded or multi process environments without address isolation,
If the ownership, global variables, and competition relationships of fd are not properly handled,
there may be issues with fd duplication or accidental closure.
Further leading to the following issues, which are difficult to troubleshoot.

1. Security vulnerability: the fd we wrote is not the expected fd and will be accessed by hackers to obtain data
2. Program exceptions or crashes: write or read fd failures, and program logic errors
3. The structured file XML or database is damaged: the data format written to the database is not the expected format.

The implementation principle of fdsan is based on the implementation of Android
https://android.googlesource.com/platform/bionic/+/master/docs/fdsan.md

717bb04cb7 Increase the number of real time signals. Two is not enough.
Refer to issue #8867 for details and rational.

Convert sigset_t to an array type so that more than 32 signals can be supported.

Why not use a uin64_t?
- Using a uin32_t is more flexible if we decide to increase the number of signals beyound 64.
- 64-bit accesses are not atomic, at least not on 32-bit ARMv7-M and similar
- Keeping the base type as uint32_t does not introduce additional overhead due to padding to achieve 64-bit alignment of uin64_t
- Some architectures still supported by NuttX do not support uin64_t
  types,

Increased the number of signals to 64. This matches Linux. This will support all xsignals defined by Linux and also 32 real time signals (also like Linux).

This is is a work in progress; a draft PR that you are encouraged to comment on.

07039b8a36 lib_abort.c: Change call to userspace exit() into syscall _exit()
The POSIX standard dictates that during abnormal termination the functions

optional. So in this case, it is perfectly legal / better to call the
kernel system call _exit() instead.

This fixes regression issues caused by removal exit() from the kernel.

e9ef70e24b sched/assert: Call abort() instead of exit() in assert
POSIX dictates that assert() terminates via abort(), even though in NuttX
abort() just calls exit(EXIT_FAILURE) it is better to use the correct
API here, if at some point a proper implementation for abort() is made.

Also, as the kernel must not use abort() which is a userspace API, direct
the exit to PANIC() if for some reason _assert() returns (it should not
but trap it here just in case).

2e5a20612c libc: unistd: lib_getrlimit: return a value for RLIMIT_NOFILE request.
In the Nim language "selectors"(I/O multiplexing) module, the maximum
number of file descriptors is obtained with getrlimit() as follows.

        var fdLim: RLimit
        var res = int(getrlimit(RLIMIT_NOFILE, fdLim))
        if res >= 0:
          res = int(fdLim.rlim_cur) - 1

To be able to use the same implementation as other POSIX-based OS,
getrlimit() should return a value.
(For now, let it return 128.)

409e2f3701 drivers/serial, libc/termios: Implement tcsendbreak
The TERMIOS(3) function tcsendbreak() and the IOCTLs TCSBRK and TCSBRKP
transmit a serial line Break.

Previously NuttX included an extern declaration for tcsendbreak() and
defines for TCSBRK and TCSBRKP but none of these were implemented.
Attempting to build programs that called tcsendbreak() would fail with
a linker error; attempting to use TCSBRK and TCSBRKP would result in an
error at runtime.

This changeset adds the tcsendbreak() function and handling for TCSBRK
and TCSBRKP; tcsendbreak() is implemented in terms of TCSBRK. Both
TCSBRK and TCSBRKP are implemented in terms of the BSD-compatible Break
IOCTLs TIOCSBRK and TIOCCBRK, which must be provided by the lower half
serial driver. Currently, not all lower half serial drivers in NuttX
support these IOCTLs. Those that do implement them may need one or more
Kconfig options to be set, such as `CONFIG_*_U[S]ART_BREAKS` and, on
some architectures, a separate `CONFIG_*_SERIALBRK_BSDCOMPAT`.

* drivers/serial/serial.c
  (uart_tcsendbreak): New function.
  (uart_ioctl): Implement TCSBRK and TCSBRKP.

* libs/libc/termios/lib_tcsendbreak.c
  (): New file.

* libs/libc/termios/Make.defs
  (CSRCS): Add lib_tcsendbreak.c to the build.

Thanks to Xiang Xiao for PR feedback.

172b209f2d sched/assert: Re-implement assert() into user space
_assert is a kernel procedure, entered via system call to make the core
dump in privileged mode.

Running exit() from this context is not OK as it runs the registered
exit functions and flushes streams, which must not be done
from privileged mode as it is a security hole.

Thus, implement assert() into user space (again) and remove the exit()
call from the kernel procedure.

d3ffeb40a7 libc/machine/xtensa: make longjmp safe against context switch
In order to turn longjmp context-switch safe, it's necessary
to disable interrupts before modifying windowbase and windowstart.
Otherwise, after a context switch, windowstart and windowbase
would be different, leading to a wrongly set windowstart bit due to
longjmp writing it based on the windowbase before the context switch.
This corrupts the registers at the next window overflow reaching
that wrongly set bit.

*Background:*
This PR is related to an issue first observed on ESP-IDF
https://github.com/espressif/esp-idf/issues/5229 and it was, then,
checked on NuttX using a test application.

*The test application:*
To check if the problem affects ESP32, ESP32-S2 and ESP32-S3 on
NuttX, it was created an application based on:
https://en.cppreference.com/w/c/program/longjmp

The application creates 16 tasks (`#define NUMBER_OF_TASKS  16`)
that implements the following daemon:

```
static int setjmp_longjmp_daemon(int argc, char *argv[])
{
  for (int i = 0; i < NUMBER_OF_TASKS * 2; i++)
    {
      jmp_buf env;

      volatile int count = 0;
      if (setjmp(env) != UINT16_MAX)
        {
          foo(&env, ++count);
        }
    }

  sem_post(&g_sem);

  return EXIT_SUCCESS;
}
```

The main function also initializes a semaphore to avoid application
exiting before tasks return successfully:

```
  sem_init(&g_sem, 0, -NUMBER_OF_TASKS);
```

Finally, the round-robin interval was lowered to 1ms to raise the
chances of the longjmp being interrupted by a context switch
(`CONFIG_RR_INTERVAL=1).

This setup was able to reproduce the problem prior to this patch
being applied.

db4840564d dns: Reduce the dns_lock granularity
When a7 curl calls dns_query via usrsock, it will wait a usrsock
response with the dns lock held. If a7 rptun recv a dns_addnameserver
event from another core at this time, rptun waits the lock held by
curl in callback. Then curl will never get its usrsock response with
rptun blocked, so the deadlock occurs.

This change will break lock when do usrsock request.

daf39c03bd dns_client: directly initialize g_dns_servers and remove dns_initialize directly
g_dns_servers need init before dns_query, Otherwise sim can not add default
dns server when use usrsock mode to share host network.

Avoid similar problems in the future, so directly initialize g_dns_servers.
