Subject: [PATCH] build: support explicitly disabling netcf
placing "-Dnetcf=disabled" on the meson commandline was ignored,
meaning that even with that option the build would get WITH_NETCF if
the netcf-devel package was found - the only way to disable it was to
uninstall netcf-devel.
This patch adds the small bit of logic to check the netcf meson
commandline option (in addition to whether netcf-devel is installed)
before defining WITH_NETCF.

Subject: [PATCH] virSetUIDGIDWithCaps: Don't drop CAP_SETPCAP right away
There are few cases where we execute a virCommand with all caps
cleared (virCommandClearCaps()). For instance
dnsmasqCapsRefreshInternal() does just that. This means, that
after fork() and before exec() the virSetUIDGIDWithCaps() is
called. But since the caller did not want to change anything,
just drop capabilities, these are the values of arguments:
virSetUIDGIDWithCaps (uid=-1, gid=-1, groups=0x0, ngroups=0,
capBits=0, clearExistingCaps=true)
This means that indeed all capabilities will be dropped,
including CAP_SETPCAP. But this capability controls whether
capabilities can be set, IOW whether capng_apply() succeeds.
There are two calls of capng_apply() in the function. The
CAP_SETPCAP is dropped after the first call and thus the other
call (capng_apply(CAPNG_SELECT_BOUNDS);) fails.
The solution is to keep the capability for as long as needed
(just like CAP_SETGID and CAP_SETUID) and drop it only at the
very end (just like CAP_SETGID and CAP_SETUID).

Subject: [PATCH] security: fix SELinux label generation logic
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
A process can access a file if the set of MCS categories
for the file is equal-to *or* a subset-of, the set of
MCS categories for the process.
If there are two VMs:
a) svirt_t:s0:c117
b) svirt_t:s0:c117,c720
Then VM (b) is able to access files labelled for VM (a).
IOW, we must discard case where the categories are equal
because that is a subset of many other valid category pairs.

Subject: [PATCH] virSetUIDGIDWithCaps: Set bounding capabilities only with
CAP_SETPCAP
In one of my previous patches I've tried to postpone dropping
CAP_SETPCAP until the very end because it's needed for
capng_apply(). What I did not realize back then was that we might
not have the capability to begin with. Because of unknown reasons
capng_apply() pollutes logs only for CAPNG_SELECT_BOUNDS and not
for CAPNG_SELECT_CAPS.
Reproducer is really simple: run libvirtd as a regular user.
During its initialization, libvirtd will spawn some binaries
(dnsmasq, qemu-*, etc.) and while doing so it will try to drop
capabilities.
Anyway, let's call capng_apply(CAPNG_SELECT_BOUNDS) only if we
have the CAP_SETPCAP (which is tracked in need_setpcap variable).

When QEMU introduces new firmware features libvirt will fail until we

We should simply ignore the new feature until we add a proper support

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.

Subject: [PATCH] Allow control over QEMU audio backend
When using VNC for graphics + keyboard + mouse, we shouldn't
then use the host OS for audio. Audio should go back over
VNC.
When using SDL for graphics, we should use the host OS for
audio since that's where the display is. We need to allow
certain QEMU env variables to be passed through to guest
too to allow choice of QEMU audio backend.
* qemud/libvirtd.sysconf: Mention QEMU/SDL audio env vars
* src/qemu_conf.c: Passthrough QEMU/SDL audio env for SDL display,
disable host audio for VNC display

Subject: [PATCH] Fix memory leaks in libvirtd's message processing
Commit 47cab734995fa9521b1df05d37e9978eedd8d3a2 changed the way how
qemud_client_message objects were reused. Before this commit
remoteDispatchClientRequest() reused the received message for normal responses
and to report non-fatal errors. If a fatal error occurred qemudWorker() frees
the message. After this commit non-fatal errors are reported by
remoteSerializeReplyError() using a new qemud_client_message object and the
original message leaks.
To fix this leak the original message has to be freed if
remoteSerializeReplyError() succeeds. If remoteSerializeReplyError()
fails the original message is freed in qemudWorker().
* daemon/dispatch.c: free qemud_client_message objects that will not be reused
and would leak otherwise, also free the allocated qemud_client_message object
in remoteSerializeError() if an error occurs

Subject: [PATCH] Fix QEMU restore from file in raw format
The logic for running the decompression programs was broken in
commit f238709304f9f6c57204cdd943e542cbae38fa5f, so that for
non-raw formats the decompression program was never run, and
for raw formats, it tried to exec an argv[] with initial NULL
in the program name.
* src/qemu/qemu_driver.c: Fix logic in runing decompression program

Subject: [PATCH] Fix virFileReadLimFD/virFileReadAll to handle EINTR
The fread_file_lim() function uses fread() but never handles
EINTR results, causing unexpected failures when reading QEMU
help arg info. It was unneccessarily using FILE * instead
of plain UNIX file handles, which prevented use of saferead()
* src/util/util.c: Switch fread_file_lim over to use saferead
instead of fread, remove FILE * use, and rename
(cherry picked from commit 11a36d956cb8a5e439e535bff3e0cfce50a64bca)

Subject: [PATCH] Fix xen driver refcounting.
The commit cb51aa48a777ddae6997faa9f28350cb62655ffd "Fix up connection
reference counting." changed the driver closing and virConnectPtr
unref-logic in virConnectClose().
Before this commit virConnectClose() closed all drivers of the given
virConnectPtr and virUnrefConnect()'ed it afterwards. After this
commit the driver-closing is done in virUnrefConnect() if and only if
the ref-count of the virConnectPtr dropped to zero.
This change in execution order leads to a virConnectPtr leak, at least
for connections to Xen.
The relevant call sequences:
virConnectOpen() -> xenUnifiedOpen() ...
... xenInotifyOpen() -> virConnectRef(conn)
... xenStoreOpen() -> xenStoreAddWatch() -> conn->refs++
virConnectClose() -> xenUnifiedClose() ...
... xenInotifyClose() -> virUnrefConnect(conn)
... xenStoreClose() -> xenStoreRemoveWatch() -> virUnrefConnect(conn)
Before the commit this additional virConnectRef/virUnrefConnect calls
where no problem, because virConnectClose() closed the drivers
explicitly and the additional refs added by the Xen subdrivers were
removed properly. After the commit this additional refs result in a
virConnectPtr leak (including a leak of the hypercall file handle;
that's how I noticed this problem), because now the drivers are only
close if and only if the ref-count drops to zero, but this cannot
happen anymore, because the additional refs from the Xen subdrivers
would only be removed if the drivers get closed, but that doesn't
happen because the ref-count cannot drop to zero.
The fix for this problem is simple: remove the
virConnectRef/virUnrefConnect calls from the Xen subdrivers (see
attached patch). Maybe someone could explain why the Xen Inotify and
Xen Store driver do this extra ref-counting, but none of the other Xen
subdrivers. It seems unnecessary to me and can be removed without
problems.

and start a guest with:
<domain type='kvm'>

Subject: [PATCH] Don't copy old machines from a domain which has none
If the the qemu and kvm binaries are the same, we don't include machine
types in the kvm domain info.
However, the code which refreshes the machine types info from the
previous capabilities structure first looks at the kvm domain's info,
finds it matches and then copies the empty machine types list over
for the top-level qemu domain.
That doesn't make sense, we shouldn't copy an empty machin types list.
* src/qemu/qemu_conf.c: qemudGetOldMachinesFromInfo(): don't copy an
empty machine types list.

Subject: [PATCH] storage: Fix generating iscsi 'auth' xml
