* block/gluster: Remove deprecated RDMA protocol handlingPhilippe Mathieu-Daudé2024-04-241-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | GlusterFS+RDMA has been deprecated 8 years ago in commit 0552ff2465 ("block/gluster: deprecate rdma support"): gluster volfile server fetch happens through unix and/or tcp, it doesn't support volfile fetch over rdma. The rdma code may actually mislead, so to make sure things do not break, for now we fallback to tcp when requested for rdma, with a warning. If you are wondering how this worked all these days, its the gluster libgfapi code which handles anything other than unix transport as socket/tcp, sad but true. Besides, the whole RDMA subsystem was deprecated in commit e9a54265f5 ("hw/rdma: Deprecate the pvrdma device and the rdma subsystem") released in v8.2.

* block: better document SSH host key fingerprint checkingDaniel P. Berrangé2022-02-161-4/+26
| | | | | | | | | | The docs still illustrate host key fingerprint checking using the old md5 hashes which are considered insecure and obsolete. Change it to illustrate using a sha256 hash. Also show how to extract the hash value from the known_hosts file. Reviewed-by: Hanna Reitz <hreitz@redhat.com> Signed-off-by: Daniel P. Berrangé <berrange@redhat.com>

| | | | | | | | | | | | | It's intended to be inserted between format and protocol nodes to preallocate additional space (expanding protocol file) on writes crossing EOF.

* docs/system: put qemu-block-drivers body in an included filePaolo Bonzini2020-03-061-0/+954
This removes the "only" directives, and lets us use the conventional "DESCRIPTION" section in the manpage. This temporarily drops the qemu-block-drivers documentation from the system manual, but it will be put back (in the right place in the toctree) in a later commit.
