Hi all,
This series backports three upstream commits: - 135ffc7 "bpf, vsock: Invoke proto::close on close()" - fcdd224 "vsock: Keep the binding until socket destruction" - 78dafe1 "vsock: Orphan socket after transport release"
Although this version of the kernel does not support sockmap, I think backporting this patch can be useful to reduce conflicts in future backports [1]. It does not harm the system. The comment it introduces in the code can be misleading. I added some words in the commit to explain the situation.
The other two commits are untouched, fixing a use-after free[2] and a null-ptr-deref[3] respectively.
