Stefano Garzarella says: ==================== vsock: some fixes due to transport de-assignment v1: https://lore.kernel.org/netdev/20250108180617.154053-1-sgarzare@redhat.com/ v2: - Added patch 3 to cancel the virtio close delayed work when de-assigning the transport - Added patch 4 to clean the socket state after de-assigning the transport - Added patch 5 as suggested by Michael and Hyunwoo Kim. It's based on Hyunwoo Kim and Wongi Lee patch [1] but using WARN_ON and covering more functions - Added R-b/T-b tags This series includes two patches discussed in the thread started by Hyunwoo Kim a few weeks ago [1], plus 3 more patches added after some discussions on v1 (see changelog). All related to the case where a vsock socket is de-assigned from a transport (e.g., because the connect fails or is interrupted by a signal) and then assigned to another transport or to no-one (NULL). I tested with usual vsock test suite, plus Michal repro [2]. (Note: the repo works only if a G2H transport is not loaded, e.g. virtio-vsock driver). The first patch is a fix more appropriate to the problem reported in that thread, the second patch on the other hand is a related fix but of a different problem highlighted by Michal Luczaj. It's present only in vsock_bpf and already handled in af_vsock.c The third patch is to cancel the virtio close delayed work when de-assigning the transport, the fourth patch is to clean the socket state after de-assigning the transport, the last patch adds warnings and prevents null-ptr-deref in vsock_*[has_data|has_space]. Hyunwoo Kim, Michal, if you can test and report your Tested-by that would be great!

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 reStructuredText 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.
