1. Remove single !events condition check to deliver the missed event even though there is no new event happened. Consider this case: 1) nf_ct_deliver_cached_events is invoked at the first time, the event is failed to deliver, then the missed is set. 2) nf_ct_deliver_cached_events is invoked again, but there is no any new event happened. The missed event is lost really. It would try to send the missed event again after remove this check. And it is ok if there is no missed event because the latter check !((events | missed) & e->ctmask) could avoid it. 2. Correct the return value check of notify->fcn. When send the event successfully, it returns 0, not postive value. Signed-off-by: Gao Feng <fgao@ikuai8.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
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.
