Ubuntu 18.04 and "sig_hashalgo: md4"

[Jeffrey Walton]

Hi Everyone,

Ubuntu 18.04's modinfo looks like it is subject to
https://bugzilla.redhat.com/show_bug.cgi?id=1320921 and
https://bugzilla.redhat.com/show_bug.cgi?id=1490975.

$ modinfo crypto_simd
filename:   /lib/modules/5.3.0-66-generic/kernel/crypto/crypto_simd.ko
license:GPL
srcversion: 701320EC07F22E0D8427859
depends:cryptd
retpoline:  Y
intree: Y
name:   crypto_simd
vermagic:   5.3.0-66-generic SMP mod_unload
signat: PKCS#7
signer:
sig_key:
sig_hashalgo:   md4

A quick Google search did not pick up a similar Ubuntu bug report,
like Red Hat's 1320921 and 1490975.

It looks like the fix was checked in about a year and a half ago. Also
see https://lwn.net/Articles/779249/.

Would it be possible to pick up the fix?

Thanks in advance.

Hi,

installing the package:

sudo apt update
sudo apt install nwipe

https://packages.ubuntu.com/focal/nwipe

"/usr/sbin/nwipe"
- https://packages.ubuntu.com/focal/amd64/nwipe/filelist

The manual page:

http://manpages.ubuntu.com/manpages/focal/man1/nwipe.1.html

It's just one program named nwipe.

A hint:

"To summarize, securely overwriting hard disk drives involves:

One overwriting pass for most HDD erasure. Remember to weigh data
sensitivity against the costs of higher level of security and the
time you want to spend on each processed asset. More passes take
longer and are usually unnecessary." -

Regards,
Ralf
