            Bug ID: 228094
           Summary: IPSec/AES GCM broken using AESNI
           Product: Base System
           Version: CURRENT
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Many People
          Priority: ---
         Component: kern
          Assignee: bugs at FreeBSD.org
          Reporter: emeric.poupon at stormshield.eu

Hello,

AES-GCM-16 in IPSec/ESP seems to be broken using aesni on HEAD: all the emitted
ciphered packets are dropped by the remote host. However, everything works as
expected using cryptosoft.

Please also note that If I revert aesni to r324036, aesni works fine again. So
maybe r325037 is responsible for this regression?

Regards,
