[PATCH v2] meson: allow systemd sysusersdir to be changed
by Daniel P. Berrangé 10 Jun '24

10 Jun '24

We currently hardcode the systemd sysusersdir, but it is desirable to be able to choose a different location in some cases. For example, Fedora flatpak builds change the RPM %_sysusersdir macro, but we can't currently honour that. Reported-by: Yaakov Selkowitz <yselkowi(a)redhat.com> Signed-off-by: Daniel P.

[PATCH] network: allow for forward dev to be a transient interface
by Laine Stump 07 Jun '24

07 Jun '24

A user reported that if they set <forward mode='nat|route' dev='blah'> starting the network would fail if the device 'blah' didn't already exist. This is caused by using "iif" and "oif" in nftables rules to check for the forwarding device - these two commands work by saving the named interface's ifindex (an unsigned integer) when the rule is added, and comparing it to the ifindex associated with the packet's path at runtime. This works great if the interface both 1) exists when the rule is added, and 2) is never deleted and re-created after the rule is added (since it would end up with a different ifindex). When checking for the network's bridge device, it is okay for us to use "iif" and "oif", because the bridge device is created before the firewall rules are added, and will continue to exist until just after the firewall rules are deleted when the network is shutdown. But since the forward device might be deleted/re-added during the lifetime of the network's firewall rules, we must instead us "oifname" and "iifname" - these are much less efficient than "Xif" because they do a string compare of the interface's name rather than just comparing two integers (ifindex), but they don't require the interface to exist when the rule is added, and they can properly cope with the named interface being deleted and re-added later.

[PATCH] rpm: drop cyrus-sasl dep

We link to libsasl2.so, so get a dep on cyrus-sasl-libs automatically. The dep on cyrus-sasl-gssapi gets us the mechanism that matches our default config. The 'cyrus-sasl' package merely contains some man pages and the saslauthd daemon, which is not required by libvirt.

Schema test result can be inverted by naming the file with '-invalid.xml' suffix. In such case the test will require that the XML has invalid schema. Additionally it's also possible by adding an exception in virschematest, but we have more than a few tests with the suffix in qemuxmlconftest.

[PATCH] qemu_block: Validate number of hosts for iSCSI disk device
by Rayhan Faizel 06 Jun '24

06 Jun '24

An iSCSI device with zero hosts will result in a segmentation fault. This patch adds a check for the number of hosts, which must be one in the case of iSCSI. Minimal reproducing XML: <domain type='qemu'> <name>MyGuest</name> <uuid>4dea22b3-1d52-d8f3-2516-782e98ab3fa0</uuid> <os> <type arch='x86_64'>hvm</type> </os> <memory>4096</memory> <devices> <disk type='network'> <source name='dummy' protocol='iscsi'/> <target dev='vda'/> </disk> </devices> </domain> Signed-off-by: Rayhan Faizel <rayhan.faizel(a)gmail.com> --- This crashing XML was detected by the WIP fuzzer which is being developed as part of Google Summer of Code 2024. src/qemu/qemu_block.c | 6 ++++++ 1 file changed, 6 insertions(+) diff --git a/src/qemu/qemu_block.c b/src/qemu/qemu_block.c index 738b72d7ea..d6cdf521c4 100644 --- a/src/qemu/qemu_block.c +++ b/src/qemu/qemu_block.c @@ -602,6 +602,12 @@ qemuBlockStorageSourceGetISCSIProps(virStorageSource *src, * } */ + if (src->nhosts != 1) { + virReportError(VIR_ERR_INTERNAL_ERROR, "%s", + _("iSCSI protocol accepts only one host")); + return NULL; + } + target = g_strdup(src->path); /* Separate the target and lun */ -- 2.34.1

[PATCH 0/2] lib: Annotate more functions as NULL terminated
by Michal Privoznik 06 Jun '24

06 Jun '24

I'm working on something that's calling qemuMonitorCreateObjectProps() and was getting random errors only to find out I was missing NULL sentinel. This sparked me to look at other functions that might be missing the G_GNUC_NULL_TERMINATED attribute too and found some.
