These counters are defined as part of the linux private MIB. These counters can be viewed in /proc/net/xfrm_stat. Inbound errors ~~~~~~~~~~~~~~ XfrmInError: All errors which is not matched others XfrmInBufferError: No buffer is left XfrmInHdrError: Header error XfrmInNoStates: No state is found i.e. Either inbound SPI, address, or IPsec protocol at SA is wrong XfrmInStateProtoError: Transformation protocol specific error e.g. SA key is wrong XfrmInStateModeError: Transformation mode specific error XfrmInStateSeqError: Sequence error i.e. Sequence number is out of window XfrmInStateExpired: State is expired XfrmInStateMismatch: State has mismatch option e.g. UDP encapsulation type is mismatch XfrmInStateInvalid: State is invalid XfrmInTmplMismatch: No matching template for states e.g. Inbound SAs are correct but SP rule is wrong XfrmInNoPols: No policy is found for states e.g. Inbound SAs are correct but no SP is found XfrmInPolBlock: Policy discards XfrmInPolError: Policy error XfrmAcquireError: State hasn't been fully acquired before use XfrmFwdHdrError: Forward routing of a packet is not allowed Outbound errors ~~~~~~~~~~~~~~~ XfrmOutError: All errors which is not matched others XfrmOutBundleGenError: Bundle generation error XfrmOutBundleCheckError: Bundle check error XfrmOutNoStates: No state is found XfrmOutStateProtoError: Transformation protocol specific error XfrmOutStateModeError: Transformation mode specific error XfrmOutStateSeqError: Sequence error i.e. Sequence number overflow XfrmOutStateExpired: State is expired XfrmOutPolBlock: Policy discards XfrmOutPolDead: Policy is dead XfrmOutPolError: Policy error XfrmOutStateInvalid: State is invalid, perhaps expired |
