I confirmed that the problem fixed by commit 2a63866c8b ("tipc: fix
shutdown() of connectionless socket") also applies to stream socket.
----------
#include <sys/socket.h>
#include <unistd.h>
#include <sys/wait.h>
int main(int argc, char *argv[])
{
int fds[2] = { -1, -1 };
socketpair(PF_TIPC, SOCK_STREAM /* or SOCK_DGRAM */, 0, fds);
if (fork() == 0)
_exit(read(fds[0], NULL, 1));
shutdown(fds[0], SHUT_RDWR); /* This must make read() return. */
wait(NULL); /* To be woken up by _exit(). */
return 0;
}
----------
Since shutdown(SHUT_RDWR) should affect all processes sharing that socket,
unconditionally setting sk->sk_shutdown to SHUTDOWN_MASK will be the right
behavior.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
