[PATCH RFC nf-next 0/2] ct helper object name matching

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



[ Compile tested-only and userspace update is missing ]

This patchset adds NFT_CT_HELPER_OBJNAME to match on the helper object name, ie.

>From nftables, existing (inconsistent) syntax can be left in place for
backward compatibility. The new proposed syntax would more explicitly
refer to match the user wants to do, e.g.

	ct helper name set "ftp-21"
	ct helper name "ftp-21"

For NFT_CT_HELPER_TYPE (formerly NFT_CT_HELPER), syntax would be:

	ct helper type "ftp"

It should be also possible to support for:

	ct helper type set "ftp"

via implicit object, this infrastructure is missing in the kernel
though, the idea would be to create an implicit object that is attached
to the rule.  Such object would be released when the rule is removed.

Let me know.

  netfilter: nftables: rename NFT_CT_HELPER to NFT_CT_HELPER_TYPE
  netfilter: nftables: add NFT_CT_HELPER_OBJNAME
