commit a9cc0288ba755c8c7a8dbf75b280387a21c30621 Author: yintao <[email protected]> AuthorDate: Thu Mar 6 14:47:16 2025 +0800 examples/rpmsgsocket: initialize addrlen before accept() accept4() reads addrlen as the size of the address buffer. Both stream servers passed it uninitialized, so the address could be written with an arbitrary length. Set it to sizeof(myaddr).
