Subject: inherit TAINT_PROPRIETARY_MODULE v2
Date: Thu, 30 Jul 2020 08:10:19 +0200 [thread overview]
Message-ID: <20200730061027.29472-1-hch@lst.de> (raw)
Hi Jessica,
we've had a bug in our resolution of _GPL modules since day one, that
is a module can claim to be GPL licensed and use _GPL exports, while
it also depends on symbols from non-GPL modules. This is used as a
circumvention of the _GPL exports by using a small shim module using
the _GPL exports and the other functionality. A recent example can
be found here:
https://lore.kernel.org/netdev/6376CA34-BC6F-45DE-9FFD-7E32664C7569@fb.com/T/#md514322fdfa212afe9f1d3eb4e5f7eaefece36eb
Changes since v1:
- standardize on one spelling of "license"
- fix a commit message type
