How can one observe this? Even with rpm-plugin-ima installed, steps in:
https://fedoraproject.org/wiki/Changes/Signed_RPM_Contents#How_To_Test
produce no output for any of the files I tried in a f37-beta install.
The appropriate "publiccert.der" file does not seem to be available
either.

Hello and apologies for resurrecting an old thread.
I was looking for information regarding IMA in F37 and found it was asked
but I could not see any replies.
My question is exactly the same as the OP, I do not see security.ima
attributes on files after upgrading to F37.
(https://fedoraproject.org/wiki/Changes/Signed_RPM_Contents)
```
$ getfattr --absolute-names -d -m - /usr/bin/cp
# file: /usr/bin/cp
security.selinux="system_u:object_r:bin_t:s0"
```
This output is after reinstalling coreutils. I have rpm-plugin-ima
installed.
Also, where could one find the publiccert.der certificate to perform manual
validation?
It is not published at https://getfedora.org/security/
I do not have any custom policy defined for IMA, but that should not matter:
```
$ sudo cat /sys/kernel/security/ima/policy
measure func=KEXEC_KERNEL_CHECK
measure func=MODULE_CHECK
```
Thanks.

And now I am posting to it again, so likewise appologies.

This output is after reinstalling coreutils. I have rpm-plugin-ima
installed.
There turned out to be a weird issue with the rpm on our sign vault
server and it wasn't signing things correctly. This was fixed a while
back (before the most recent mass rebuild), and f38/f39/eln rpms should
all be signed right now.
The change was re-targeted at f38 I think.
Also, where could one find the publiccert.der certificate to perform
manual
validation?
It is not published at https://getfedora.org/security/
I've just added f38/f39 ones to fedora-repos:
https://src.fedoraproject.org/rpms/fedora-repos/c/93b2c8add81f2d6f83874ce...
I meant it to be a commit to my fork for a PR, but somehow my fork got
messed up and I ended up pushing it in directly. ;(
I would appreciate feedback from anyone who knows IMA more than I...
are the certs the ones you need? Is the place I put them in fedora-repos
ok/obvious? Lots of IMA docs use /etc/keys but I figured
/etc/pki/rpm-ima made a lot more sense than a generic sounding dir like
/etc/keys.
Hope that helps.
