We avoid calling into nf_conntrack_in() for expected connections, as
that would remove the expectation that we want to stick around until
we are ready to commit the connection. Instead, we do a lookup in the
expectation table directly. However, after a successful expectation
lookup we have set the flow key label field from the master
connection, whereas nf_conntrack_in() does not do this. This leads to
master's labels being inherited after an expectation lookup, but those
labels not being inherited after the corresponding conntrack action
with a commit flag.
This patch resolves the problem by changing the commit code path to
also inherit the master's labels to the expected connection.
Resolving this conflict in favor of inheriting the labels allows more
information be passed from the master connection to related
connections, which would otherwise be much harder if the 32 bits in
the connmark are not enough. Labels can still be set explicitly, so
this change only affects the default values of the labels in presense
of a master connection.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
