Subject: [PATCH] New API: guestfs_device_name returning the drive name
For each drive added, return the name. For example calling this with
index 0 will return the string "/dev/sda". I called it
guestfs_device_name (not drive_name) for consistency with the existing
guestfs_device_index function.
You don't really need to call this function. You can follow the
advice here:
https://libguestfs.org/guestfs.3.html#block-device-naming
and assume that drives are added with predictable names like
"/dev/sda", "/dev/sdb", etc.
However it's useful to expose the internal guestfs_int_drive_name
function since especially handling names beyond index 26 is tricky
(https://rwmj.wordpress.com/2011/01/09/how-are-linux-drives-named-beyond-drive-26-devsdz/)

Subject: [PATCH] guestfs_readdir(): rewrite with FileOut transfer, to lift
protocol limit
Currently the guestfs_readdir() API can not list long directories, due to
it sending back the whole directory listing in a single guestfs protocol
response, which is limited to GUESTFS_MESSAGE_MAX (approx. 4MB) in size.
Introduce the "internal_readdir" action, for transferring the directory
listing from the daemon to the library through a FileOut parameter.
Rewrite guestfs_readdir() on top of this new internal function:
- The new "internal_readdir" action is a daemon action. Do not repurpose
the "readdir" proc_nr (138) for "internal_readdir", as some distros ship
the binary appliance to their users, and reusing the proc_nr could
create a mismatch between library & appliance with obscure symptoms.
Replace the old proc_nr (138) with a new proc_nr (511) instead; a
mismatch would then produce a clear error message. Assume the new action
will first be released in libguestfs-1.48.2.
- Turn "readdir" from a daemon action into a non-daemon one. Call the
daemon action guestfs_internal_readdir() manually, receive the FileOut
parameter into a temp file, then deserialize the dirents array from the
temp file.
This patch sneakily fixes an independent bug, too. In the pre-patch
do_readdir() function [daemon/readdir.c], when readdir() returns NULL, we
don't distinguish "end of directory stream" from "readdir() failed". This
rewrite fixes this problem -- I didn't see much value separating out the
fix for the original do_readdir().

Subject: [PATCH] guestfs_readdir(): minimize the number of send_file_write()
calls
In guestfs_readdir(), the daemon currently sends each XDR-encoded
"guestfs_int_dirent" to the library with a separate send_file_write()
call.
Determine the largest encoded size (from the longest filename that a
"guestfs_int_dirent" could carry, from readdir()'s "struct dirent"), and
batch up the XDR encodings until the next encoding might not fit in
GUESTFS_MAX_CHUNK_SIZE. Call send_file_write() only then.

Rich said in <https://bugzilla.redhat.com/show_bug.cgi?id=1844341#c1>:
> The libvirt backend has never allowed the iface parameter. We should

Remove the handling of "iface" in the direct (QEMU) backend. Refresh the
documentation regarding both backends.

Subject: [PATCH] lib: drive_create_data, drive: remove field "iface"
Representing "iface" in the "drive_create_data" and "drive" structures is
now useless; the direct backend ignores "iface", while the libvirt one
rejects it unless it is empty. Unify both backends -- make them both
ignore "iface". (Which only relaxes the libvirt backend, so it cannot
cause compatibility problems.) This lets us remove the fields. Update the
documentation as well.

RHBZ 690819 and 975797 can be enabled on all arches (regardless of
backend).

inverting the default behavior (for guests with SELinux support, that is

Removing "--selinux-relabel" in commit 2f6a27f1077d ("generator/customize:

that invoke virt-customize and/or virt-sysprep with that option. Restore
the option, with no functionality tied to it.

Subject: [PATCH] RHEL: Disable unsupported remote drive protocols
(RHBZ#962113).
This disables support for unsupported remote drive protocols:
* ftp
* ftps
* http
* https
* tftp
* gluster
* iscsi
* sheepdog
* ssh
Note 'nbd' is not disabled, and of course 'file' works.
We hope to gradually add some of these back over the lifetime of RHEL.
