Subject: [PATCH] systemd: directly notify systemd instead of using sd_notify
|
||||
|
||||
The sd_notify method is used to tell systemd when libvirtd
|
||||
has finished starting up. All it does is send a datagram
|
||||
containing the string parameter to systemd on a UNIX socket
|
||||
named in the NOTIFY_SOCKET environment variable. Rather than
|
||||
pulling in the systemd libraries for this, just code the
|
||||
notification directly in libvirt as this is a stable ABI
|
||||
from systemd's POV which explicitly allows independant
|
||||
implementations:
|
||||
|
||||
See "Reimplementable Independently" column in the
|
||||
"$NOTIFY_SOCKET Daemon Notifications" row:

When COW is not explicitly requested to be disabled or enabled, the

function is supposed to do nothing on non-BTRFS file systems.

Fixes commit 7230bc95aa78379c9ee20cf59394c5fc4305b75b.

Subject: [PATCH] virdevmapper: Don't cache device-mapper major
|
||||
|
||||
The device mapper major is needed in virIsDevMapperDevice() which
|
||||
determines whether given device is managed by device-mapper. This
|
||||
number is obtained by parsing /proc/devices and then stored in a
|
||||
global variable so that the file doesn't have to be parsed again.
|
||||
However, as it turns out this logic is flawed - the major number
|
||||
is not static and can change as it can be specified as a
|
||||
parameter when loading the dm-mod module.
|
||||
|
||||
Unfortunately, I was not able to come up with a good solution and
|
||||
thus the /proc/devices file is being parsed every time we need
|
||||
the device mapper major.

Subject: [PATCH] virdevmapper: Handle kernel without device-mapper support
|
||||
|
||||
In one of my latest patch (v6.6.0~30) I was trying to remove
|
||||
libdevmapper use in favor of our own implementation. However, the
|
||||
code did not take into account that device mapper can be not
|
||||
compiled into the kernel (e.g. be a separate module that's not
|
||||
loaded) in which case /proc/devices won't have the device-mapper
|
||||
major number and thus virDevMapperGetTargets() and/or
|
||||
virIsDevMapperDevice() fails.
|
||||
|
||||
However, such failure is safe to ignore, because if device mapper
|
||||
is missing then there can't be any multipath devices and thus we
|
||||
don't need to allow the deps in CGroups, nor create them in the
|
||||
domain private namespace, etc.

||||

Subject: [PATCH] virdevmapper: Ignore all errors when opening
|
||||
/dev/mapper/control
|
||||
|
||||
So far, only ENOENT is ignored (to deal with kernels without
|
||||
devmapper). However, as reported on the list, under certain
|
||||
scenarios a different error can occur. For instance, when libvirt
|
||||
is running inside a container which doesn't have permissions to
|
||||
talk to the devmapper. If this is the case, then open() returns
|
||||
-1 and sets errno=EPERM.
|
||||
|
||||
Assuming that multipath devices are fairly narrow use case and
|
||||
using them in a restricted container is even more narrow the best
|
||||
fix seems to be to ignore all open errors BUT produce a warning
|
||||
on failure. To avoid flooding logs with warnings on kernels
|
||||
without devmapper the level is reduced to a plain debug message.

Content-Transfer-Encoding: 8bit
|
||||
|
||||
In v6.3.0-rc1~67 I've made a switch: instead of listening on udev
|
||||
events the nodedev driver started listening for kernel events.
|
||||
This was because when a device changes its name (e.g. NICs) we
|
||||
will get "move" event with DEVPATH_OLD property set, which we can
|
||||
then use to remove the old device and thus keep our internal list
|
||||
up to date. The switch to "kernel" source was made because if the
|
||||
old NICs naming (eth0, eth1, ...) is enabled (e.g. via
|
||||
net.ifnames=0 on the kernel cmd line) then udev overwrites the
|
||||
property with the new name making our internal list go out of
|
||||
sync. Interestingly, when the od NICs naming is not enabled then
|
||||
the DEVPATH_OLD contains the correct value.
|
||||
|
||||
But as it turns out, "kernel" source might be missing some other
|
||||
important properties, e.g. USB vendor/product IDs. Therefore,
|
||||
switch back to "udev" source and wish the best of luck to users
|
||||
using the old NICs naming.
