I guess the question was to David (and I prefer him to clarify).

I see patches backported to stable already, e.g. for 6.6.x stable:

$ git show afc360e8a1256acb7579a6f5b6f2c30b85b39301
commit afc360e8a1256acb7579a6f5b6f2c30b85b39301

    keys, dns: Allow key types (eg. DNS) to be reclaimed immediately on expiry

    [ Upstream commit 39299bdd2546688d92ed9db4948f6219ca1b9542 ]
...

$ git tag --contains afc360e8a1256acb7579a6f5b6f2c30b85b39301
v6.6.10
v6.6.11
v6.6.12
v6.6.9

And Greg had it in his stable-queue [1]:

$ git grep -l 39299bdd2546688d92ed9db4948f6219ca1b9542
releases/5.10.206/keys-dns-allow-key-types-eg.-dns-to-be-reclaimed-imm.patch
releases/5.15.146/keys-dns-allow-key-types-eg.-dns-to-be-reclaimed-imm.patch
releases/6.1.70/keys-dns-allow-key-types-eg.-dns-to-be-reclaimed-imm.patch
releases/6.6.9/keys-dns-allow-key-types-eg.-dns-to-be-reclaimed-imm.patch

(Although it fixes the original addition of the module in 1a4240f4764a from
v2.6.36-rc1, it was probably unportable to 5.4.x and 4.19.x.)

=> I guess we can merge even the fix itself has not been released yet (there is
not even v6.8-rc1, but I suppose it will be tagged before we release LTP).

Credit for the Edward, who suggested to fix keyctl05.c [2]:

	The reason for the failure of add_key() is that the length of the incoming data
	is 5, which is less than sizeof(*v1), so keyctl05.c failed.
	Suggest modifying keyctl05.c to increase the length of the incoming data to 6
	bytes or more.
