bps helper functions

Dear developers, Is it a good idea to export kernel compression/decompression (lib/zlib_*, lib/lz*) as helper functions to enable corresponding use cases? Has this been tried before? Thanks, Ashish

Hi, Ashish,
It seems that this has not been actively discussed before. Could you describe your use case? Thanks! Yonghong On Mon, Apr 2, 2018 at 8:11 AM, riya khanna via iovisor-dev <iovisor-dev@...> wrote: Dear developers,

Oh its simply to inspect/filter/drop a compressed application packet in the kernel without incurring network stack processing.

Ashish,
Some comments below. On Sat, Apr 7, 2018 at 1:44 PM, riya khanna <riyakhanna1983@...> wrote: <ping>Could you have more details here? Maybe have a skeleton of bpf program to at least see how this helper will be used? A lot of compression happens in the application and kernel chops them into TCP stream. Or you are talking IPcomp protocol? I am not sure how bpf program could do decompression based on a single packet. Further, do we need todecompress the whole packet or on ly part of the packet?
