+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The QEMU driver uses both virtlogd and virtlockd, while the Xen driver
+uses virtlockd. The libvirtd.service unit contains deps on the socket
+units for these services, but these deps were missed in the modular
+daemons. As a result the virtlockd/virtlogd sockets are not started
+when the virtqemud/virtxend daemons are started.

+Subject: [PATCH 1/2] wireshark: Switch to tvb_bytes_to_str()
+
+When the dissector sees a byte sequence that is either an opaque
+data (xdr_opaque) or a byte sequence (xdr_bytes) it formats the
+bytes as a hex numbers using our own implementation. But
+wireshark already provides a function for it: tvb_bytes_to_str().
+NB, the reason why it returns a const string is so that callers
+don't try to free it - the string is allocated using an allocator
+which will decide when to free it.
+
+The wireshark formatter was introduced in wireshark commit of
+v1.99.2~479 and thus is present in the version we require at
+least (2.6.0).

+Subject: [PATCH 2/2] wireshark: Drop needless comment in dissect_xdr_bytes()
+
+In the dissect_xdr_bytes() there's a comment that the string
+allocated by xdr_bytes() can't be freed using xdr_free(). Well,
+that is expected because xdr_bytes() used plain calloc() AND the
+string is not an XDR struct but plain 'char *' type. Passing it
+to xdr_free() must result in weird things happening.
