Subject: [RFC PATCH liburing v1 0/3] Introduce '--use-libc' option
Hi Jens,
Hi Stefan and Guillem,
This is an RFC patch series to introduce the '--use-libc' option to the
configure script.
Currently, when compiling liburing on x86, x86-64, and aarch64
architectures, the resulting binary lacks the linkage with the standard
C library (libc).
To address the concerns raised by Linux distribution package maintainers
regarding security, it is necessary to enable the linkage of libc to
liburing. Especially right now, when the security of io_uring is being
scrutinized. By incorporating the '--use-libc' option, developers can
now enhance the overall hardening of liburing by utilizing compiler
features such as the stack protector and address sanitizer.
See the following links for viewing the discussion:

There are three patches in this series.
- The first patch removes the '--nolibc' option from the configure
script as it is no longer needed. The default build on x86, x86-64,
and aarch64 architectures is still not using libc.
- The second patch introduces the '--use-libc' option to the configure
script. This option enables the linkage of libc to liburing.
- The third patch allows the use of the stack protector when building
liburing with libc.
Please review. Thank you.
