Subject: [PATCH 1/3] X.509: Fix certificate gathering
|
||||
|
||||
Fix the gathering of certificates from both the source tree and the build tree
|
||||
to correctly calculate the pathnames of all the certificates.
|
||||
|
||||
The problem was that if the default generated cert, signing_key.x509, didn't
|
||||
exist then it would not have a path attached and if it did, it would have a
|
||||
path attached.
|
||||
|
||||
This means that the contents of kernel/.x509.list would change between the
|
||||
first compilation in a directory and the second. After the second it would
|
||||
remain stable because the signing_key.x509 file exists.
|
||||
|
||||
The consequence was that the kernel would get relinked unconditionally on the
|
||||
second recompilation. The second recompilation would also show something like
|
||||
this:
|
||||
|
||||
X.509 certificate list changed
|
||||
CERTS kernel/x509_certificate_list
|
||||
- Including cert /home/torvalds/v2.6/linux/signing_key.x509
|
||||
AS kernel/system_certificates.o
|
||||
LD kernel/built-in.o
|
||||
|
||||
which is why the relink would happen.
|
||||
|
||||
|
||||
Unfortunately, it isn't a simple matter of just sticking a path on the front
|
||||
of the filename of the certificate in the build directory as make can't then
|
||||
work out how to build it.
|
||||
|
||||
So the path has to be prepended to the name for sorting and duplicate
|
||||
elimination and then removed for the make rule if it is in the build tree.

The bug was introduced by commit f36f8c75, two typos are in that commit:

CONFIG_KEYS_KERBEROS_CACHE should be CONFIG_PERSISTENT_KEYRINGS and

krb_cache_register_sem should be persistent_keyring_register_sem.
