In nfqueue, two consecutive skbuffs may race to create the conntrack entry. Hence, the one that loses the race gets dropped due to clash in the insertion into the hashes from the nf_conntrack_confirm() path. This patch adds a new nf_conntrack_update() function which searches for possible clashes and resolve them. NAT mangling for the packet losing race is corrected by using the conntrack information that won race. In order to avoid direct module dependencies with conntrack and NAT, the nf_ct_hook and nf_nat_hook structures are used for this purpose. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
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.
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.
