bpf, sockmap: SK_DROP on attempted redirects of unsupported af_vsock
Don't mislead the callers of bpf_{sk,msg}_redirect_{map,hash}(): make sure to immediately and visibly fail the forwarding of unsupported af_vsock packets. Fixes: 634f1a7110b4 ("vsock: support sockmap") Signed-off-by: Michal Luczaj <mhal@rbox.co> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Acked-by: John Fastabend <john.fastabend@gmail.com> Link: https://lore.kernel.org/bpf/20241013-vsock-fixes-for-redir-v2-1-d6577bbfe742@rbox.co
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.
