Subject: [PATCH] certs: Redirect openssl error message to null device

From: Stefan Berger <[email protected]>

Address the following issue detected by the kernel test robot when
there's no certificate file at the time when checking for the type
of key in the cert:

Can't open certs/signing_key.pem for reading, No such file or directory

The simplest solution is to redirect openssl's stderr output to /dev/null.

Fixes: 28d62d945ded ("certs: Trigger creation of RSA module signing key if it's not an RSA key")

Jarkko,

can you please squash this patch into the one it fixes. Unfortunately
when rebasing you will have to fix the subsequent patch from this merge
error

ifeq ($(openssl_available),yes)
<<<<<<< HEAD
X509TEXT=$(shell openssl x509 -in $(CONFIG_MODULE_SIG_KEY) -text
2>/dev/null)
=======
X509TEXT=$(shell openssl x509 -in $(CONFIG_MODULE_SIG_KEY) -text)
endif
>>>>>>> 87e968848116 (certs: Add support for using elliptic curve keys
for signing modules)

to this:


ifeq ($(openssl_available),yes)
X509TEXT=$(shell openssl x509 -in $(CONFIG_MODULE_SIG_KEY) -text
2>/dev/null)
endif

Thanks.

   Stefan

The problem is that I have already a pending pull request, and merge window
is soon closing.

I think it's a better idea that I just drop these patches and send a new
pull request, and you should construct a new version of the series. This
cannot be a blocker for the rest of the patches (or even potential
blocker). We can consider the current patches not ready for mainline.

I posted v7 based on what you had queue for the PR with the changes that
I document for v7.
