The "zero-copy" path in SW TLS will engage either for no skbs or for all but last. If the recvmsg parameters are right and the socket can do ZC we'll ZC until the iterator can't fit a full record at which point we'll decrypt one more record and copy over the necessary bits to fill up the request. The only reason we hold onto the ZC skbs which went thru the async path until the end of recvmsg() is to count bytes. We need an accurate count of zc'ed bytes so that we can calculate how much of the non-zc'd data to copy. To allow freeing input skbs on the ZC path count only how much of the list we'll need to consume. Signed-off-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
