Created edk2 tracking bugs for this issue:

Affects: epel-7 [bug 1971725]
Affects: fedora-all [bug 1971726]

Comment 2 Laszlo Ersek 2021-06-23 09:40:29 UTC

Hello Guilherme,

IpSecDxe is not included in any firmware binary we ship, in any Fedora or RHEL release.

(IpSecDxe is not included in any ArmVirtPkg or OvmfPkg platform even upstream.)

Thanks,
Laszlo

Comment 3 Laszlo Ersek 2021-06-23 09:46:08 UTC

(In fact, upstream edk2 removed the ipsec driver altogether, in commit d55d9d066436 ("NetworkPkg: Remove IpSec driver and application", 2019-04-29); for TianoCore#1697.)

Comment 4 Marco Benatto 2021-07-02 19:45:58 UTC

As mentioned by Laszlo IpSecDxe was removed back in 2019 from edk2. Both Red Hat Enterprise 8 version is newer than the version where the commit was introduced and doesn't ship the affected component.
