[ Upstream commit57b0c9d49b] If a call-level abort is received for the previous call to complete on a connection channel, then that abort is queued for the connection processor to handle. Unfortunately, the connection processor then assumes without checking that the abort is connection-level (ie. callNumber is 0) and distributes it over all active calls on that connection, thereby incorrectly aborting them. Fix this by discarding aborts aimed at a completed call. Further, discard all packets aimed at a call that's complete if there's currently an active call on a channel, since the DATA packets associated with the new call automatically terminate the old call.

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.
