Change the default udev rule for /dev/ptp* from 0660 to 0664,
allowing unprivileged users read-only access.
NIC telemetry and hardware logs often use device timestamps that must
be correlated with host time via read-only PTP ioctls (e.g.
cross-timestamp queries). Requiring privileged access makes these
workflows unnecessarily restrictive.
Older kernels lacked proper permission checks in some PTP ioctls.
Kernel commit b4e53b15c04e3852949003752f48f7a14ae39e86 ("ptp: Add PHC
file mode checks. Allow RO adjtime() without FMODE_WRITE.") introduces
the necessary file mode validation, ensuring that read access does not
permit clock modification or configuration changes, which still require
write permissions.
This commit has been backported to all actively maintained stable
kernel branches.

Observed with the tpm2 provider and the tpm2tss engine was that the
auth process failed because the provider/engine could not ask for the
PIN through the callback, resulting in:
"Failed to load private key from ...: Input/output error"
Apparently the default UI method is not enough and the key setup
functions expect an explicit method.
Pass the existing UI method through as callback for the key setup.
The warning will still be reported if XAUTHORITY is set but not exported.
However, such scenario is unlikely for xinitrc.d scripts environment.

Follow-up to 02cab70acf. pe_hash(),
section_offset_cmp() and uki_hash() still had a bunch of raw accesses
to LE fields (e_lfanew, SizeOfHeaders, PointerToRawData, SizeOfRawData,
VirtualSize, certificate_table->Size) without le32toh(), so they'd
produce garbage on big-endian.
Also wrap VirtualSize in bootspec.c for consistency.
This was made a strv to handle either directories or raw images but
since we now handle that via multiple PickFilter instances, we don't
need suffixes to be a strv anymore.
Fixes failure on Rawhide:

You can register whatever process you want in the user machined instance
that is running in the same namespace as pid 1 as machined won't be allowed
to do anything privileged anyway that could be dangerous when running as a user
instance.
We have to skip the check as we user machined instances don't have
privileges to inspect pid1's user namespaces.
Set `persist-credentials: false` for actions/checkout.
By default, using `actions/checkout` causes a credential to be persisted on
disk. Subsequent steps may accidentally publicly persist the credential, e.g.
by including it in a publicly accessible artifact via actions/upload-artifact.
However, even without this, persisting the credential on disk is non-ideal
unless actually needed.

By default, Dependabot does not perform any cooldown on dependency updates.
In other words, a regularly scheduled Dependabot run may perform an update
on a dependency that was just released moments before the run began.
This presents both stability and supply-chain security risks.
To mitigate these risks, explicitly set Dependabot cooldown period to 7 days.

Otherwise, OOM error will never checked, and the "preferred" setting
always emits warning that the field is unknown.

Fixes CID#1645063.
ID_INTEGRATION is not being updated with hwdb entries, asign the new
value to it when hwdb has been imported.
We still need the 65-integration.rule assignment for devices that aren't
in hwdb.
While at it remove unneeded check in 70-touchpad.rules, as it was not
added for 70-joystick.rules with the statement if ID_INPUT_* is set and
ID_INPUT not, there is a bug elsewhere. And remove unneeded gotos in
both files.

pe_hash() and uki_hash() pass pe_header->pe.NumberOfSections directly
to typesafe_qsort() and FOREACH_ARRAY() without le16toh(). On
big-endian (s390x), NumberOfSections=3 gets read as 0x0300 (768),
while pe_load_sections() correctly converts it and only allocates 3
sections. This makes qsort process 768 elements on a 3-element
buffer, causing a heap-buffer-overflow (confirmed with ASAN on
native s390x).
Wrap all three raw usages with le16toh() to match pe_load_sections().
As in the previous commit, also enable the measurement logic when
activating Verity via veritsetup rather than the dissection logic.
The logic stays close to the interface of cryptsetup for measuring the
volume key.
Let's hook up the dissection logic with the new measurement infra, and
issue the measurement after successfully unlock an image, but before
returning to the caller.
Note that ideally we'd do this measurement in the kernel, so that we can
place it after authenticating the root hash, but before activating the
medium. One day we should be able to do that via eBPF based on userspace
policies, but for now, this would require too much kernel rework.
Let's however make sure our measurements only contain data that the
kernel could know too, so that we hopefully can move these measurements
to the kernel without changing their formatting.
This adds infrastructure for measuring Verity root hashes from
userspace, along with he issuer/serial of the signatures used to unlock
them.
We measure the triplet of volume name, root hash and issuer/serial. if
confext/sysext use different signing keys then this ensures the event
log carry information about the type of image measures.
Once we start measuring Verity volumes as we activate them we want to
include information about the signature keys used, so that we can have
distinct ones for confext and for sysext and ther purposes and thus have
a cryptograpically protected hint about the kind of image we have
activated in the event log.
Ideally we'd measure a fingerprint of the signing certificate here, but
we don't have that here typically (as PKCS7 signatures used here
typically do not embed that), hence use the next best thing: the issuer
name and the serial number.
