Subject: Implementing Deletion of Set Elements in Rulesets
Date: Thu, 21 Mar 2019 11:57:15 +0530	[thread overview]
Message-ID: <CAHRz_yZQ8JYq90BCTKoN7SsivWpXMsGiFz2WkmxbX2S2aVj81Q@mail.gmail.com> (raw)

Hello,
I'm trying to implement  "deletion of set elements in ruleset". For
which I wanted to understand the way existing set operations are
implemented.
While grepping through the code I have noticed that the implementation
has some parts in the kernel, libnftnl 's dynset and the userspace's
netlink_(de)linearize .
I'm unable to get  a clear view of how the control flow goes from the
userspace's `evaluate` to the kernel's `nft_dynset.c`  in case of the
set operations.
Can someone please share some pointers in this direction?
Also how does the `set_stmt_alloc` in nftables's statement.c relate to
the `set_evaluate` in evaluate.c ?
Best Regards,
Karuna
