[libvirt] [PATCH] fix regex to check CN from server certificate

Currently when the script validates the PKI files and the certificate 'Subject:' field contains RDNs after the Common Name (CN), these values are also included, creating a false result that the CN is not correct. A small change to the sed regex fixes this issue, by extracting only the value for CN and nothing else. The regex is replaced with the exact same regex used to extract the CN value from the client certificate. --- tools/virt-pki-validate.in | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/tools/virt-pki-validate.in b/tools/virt-pki-validate.in index 206637abf..b04680dde 100755 --- a/tools/virt-pki-validate.in +++ b/tools/virt-pki-validate.in @@ -255,7 +255,7 @@ then echo CA organization: $ORG echo Server organization: $S_ORG fi - S_HOST=`"$CERTOOL" -i --infile "$LIBVIRT/servercert.pem" | grep Subject: | sed 's+.*CN=\([a-zA-Z\. _-]*\)+\1+'` + S_HOST=`"$CERTOOL" -i --infile "$LIBVIRT/servercert.pem" | grep Subject: | sed 's+.*CN=\(.[a-zA-Z \._-]*\).*+\1+'` if test "$S_HOST" != "`hostname -s`" && test "$S_HOST" != "`hostname`" then echo The server certificate does not seem to match the host name -- 2.14.3
