mainlining shenanigans
784813aed6
The smc_poll code tries to finish connect() if the socket is in state SMC_INIT and polling of the internal CLC-socket returns with EPOLLOUT. This makes sense for a select/poll call following a connect call, but not without preceding connect(). With this patch smc_poll starts connect logic only, if the CLC-socket is no longer in its initial state TCP_CLOSE. In addition, a poll error on the internal CLC-socket is always propagated to the SMC socket. With this patch the code path mentioned by syzbot https://syzkaller.appspot.com/bug?extid=03faa2dc16b8b64be396 is no longer possible.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
