Kuniyuki Iwashima f69e57925e af_unix: Annotate data-races around sk->sk_state in unix_write_space() and poll().
[ Upstream commit eb0718fb3e97ad0d6f4529b810103451c90adf94 ]

unix_poll() and unix_dgram_poll() read sk->sk_state locklessly and
calls unix_writable() which also reads sk->sk_state without holding
unix_state_lock().

Let's use READ_ONCE() in unix_poll() and unix_dgram_poll() and pass
it to unix_writable().

While at it, we remove TCP_SYN_SENT check in unix_dgram_poll() as
that state does not exist for AF_UNIX socket since the code was added.

Fixes: 1586a5877d ("af_unix: do not report POLLOUT on listeners")
Fixes: 3c73419c09 ("af_unix: fix 'poll for write'/ connected DGRAM sockets")
Fixes: 1da177e4c3 ("Linux-2.6.12-rc2")

README

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.
