[GitHub] [nuttx] jerpelea opened a new pull request, #9729: {BP-9664} libs/libc/aio/lio_listio: fix the heap use-after-free bug

jerpelea opened a new pull request, #9729:
URL: https://github.com/apache/nuttx/pull/9729

   ## Summary
   1. the lio_sigsetup() method use a universal sighand instance across all aiocb instances, but inside the lio_sighandler() method, if one aiocb is handle finished, then this method will free the sighand instance that come along with current aiocb instance. thus when handle next aiocb instance, use-after-free crash will happen. in order to solve this problem, we make each aiocb instance have their own sighand instance
   2. make the lio_listio implementation can pass the ltp/open_posix_testsuite/lio_listio testcases
   3. the modification are referred to https://pubs.opengroup.org/onlinepubs/9699919799/functions/lio_listio.html
   
   ## Impact
   RELEASE
   
   ## Testing
   NONE
