Roman Mashak says: ==================== Fix event generation for actions batch Add/Delete mode When adding or deleting a batch of entries, the kernel sends upto TCA_ACT_MAX_PRIO entries in an event to user space. However it does not consider that the action sizes may vary and require different skb sizes. For example : % cat tc-batch.sh TC="sudo /mnt/iproute2.git/tc/tc" $TC actions flush action gact for i in `seq 1 $1`; do cmd="action pass index $i " args=$args$cmd done $TC actions add $args % % ./tc-batch.sh 32 Error: Failed to fill netlink attributes while adding TC action. We have an error talking to the kernel % This patchset introduces new callback in tc_action_ops, which calculates the action size, and passes size to tcf_add_notify()/tcf_del_notify(). The patch fixes act_gact, and the rest of actions will be updated in the follow-up patches. v3: Fixed tcf_action_fill_size() to return shared attrs length when action ->get_fill_size() isn't implemented. v2: Restructured patches to make them bisectable. ==================== Signed-off-by: David S.

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.
