2021-06-01net: ethernet: rmnet: Add support for MAPv5 egress packetsSharath Chandra Vurukala1-0/+1
Adding support for MAPv5 egress packets. This involves adding the MAPv5 header and setting the csum_valid_required in the checksum header to request HW compute the checksum. Corresponding stats are incremented based on whether the checksum is computed in software or HW. New stat has been added which represents the count of packets whose checksum is calculated by the HW.

2021-06-01net: ethernet: rmnet: Support for ingress MAPv5 checksum offloadSharath Chandra Vurukala2-3/+28
Adding support for processing of MAPv5 downlink packets. It involves parsing the Mapv5 packet and checking the csum header to know whether the hardware has validated the checksum and is valid or not. Based on the checksum valid bit the corresponding stats are incremented and skb->ip_summed is marked either CHECKSUM_UNNECESSARY or left as CHEKSUM_NONE to let network stack revalidate the checksum and update the respective snmp stats. Current MAPV1 header has been modified, the reserved field in the Mapv1 header is now used for next header indication.

2021-06-01net/sched: act_vlan: Fix modify to allow 0Boris Sukholitko1-0/+1
Currently vlan modification action checks existence of vlan priority by comparing it to 0. Therefore it is impossible to modify existing vlan tag to have priority 0. For example, the following tc command will change the vlan id but will not affect vlan priority: tc filter add dev eth1 ingress matchall action vlan modify id 300 \ priority 0 pipe mirred egress redirect dev eth2 The incoming packet on eth1: ethertype 802.1Q (0x8100), vlan 200, p 4, ethertype IPv4 will be changed to: ethertype 802.1Q (0x8100), vlan 300, p 4, ethertype IPv4 although the user has intended to have p == 0. The fix is to add tcfv_push_prio_exists flag to struct tcf_vlan_params and rely on it when deciding to set the priority.

2021-06-01net/tls: Fix use-after-free after the TLS device goes down and upMaxim Mikityanskiy1-0/+9
When a netdev with active TLS offload goes down, tls_device_down is called to stop the offload and tear down the TLS context. However, the socket stays alive, and it still points to the TLS context, which is now deallocated. If a netdev goes up, while the connection is still active, and the data flow resumes after a number of TCP retransmissions, it will lead to a use-after-free of the TLS context. This commit addresses this bug by keeping the context alive until its normal destruction, and implements the necessary fallbacks, so that the connection can resume in software (non-offloaded) kTLS mode. On the TX side tls_sw_fallback is used to encrypt all packets. The RX side already has all the necessary fallbacks, because receiving non-decrypted packets is supported. The thing needed on the RX side is to block resync requests, which are normally produced after receiving non-decrypted packets. The necessary synchronization is implemented for a graceful teardown: first the fallbacks are deployed, then the driver resources are released (it used to be possible to have a tls_dev_resync after tls_dev_del). A new flag called TLS_RX_DEV_DEGRADED is added to indicate the fallback mode. It's used to skip the RX resync logic completely, as it becomes useless, and some objects may be released (for example, resync_async, which is allocated and freed by the driver).

2021-06-01evm: Verify portable signatures against all protected xattrsRoberto Sassu1-0/+6
Currently, the evm_config_default_xattrnames array contains xattr names only related to LSMs which are enabled in the kernel configuration. However, EVM portable signatures do not depend on local information and a vendor might include in the signature calculation xattrs that are not enabled in the target platform. Just including all xattrs names in evm_config_default_xattrnames is not a safe approach, because a target system might have already calculated signatures or HMACs based only on the enabled xattrs. After applying this patch, EVM would verify those signatures and HMACs with all xattrs instead. The non-enabled ones, which could possibly exist, would cause a verification error. Thus, this patch adds a new field named enabled to the xattr_list structure, which is set to true if the LSM associated to a given xattr name is enabled in the kernel configuration. The non-enabled xattrs are taken into account only in evm_calc_hmac_or_hash(), if the passed security.evm type is EVM_XATTR_PORTABLE_DIGSIG. The new function evm_protected_xattr_if_enabled() has been defined so that IMA can include all protected xattrs and not only the enabled ones in the measurement list, if the new template fields xattrnames, xattrlengths or xattrvalues have been included in the template format.

2021-05-31scsi: core: Kill DRIVER_SENSEHannes Reinecke1-0/+11
Replace the check for DRIVER_SENSE with a check for scsi_status_is_check_condition(). Audit all callsites to ensure the SAM status is set correctly. For backwards compability move the DRIVER_SENSE definition to sg.h, and update sg, bsg, and scsi_ioctl to set the DRIVER_SENSE driver_status whenever SAM_STAT_CHECK_CONDITION is present.

Add a helper function scsi_status_is_check_condition() to encapsulate the frequent checks for SAM_STAT_CHECK_CONDITION.

2021-05-31scsi: core: Introduce scsi_build_sense()Hannes Reinecke1-0/+3
Introduce scsi_build_sense() as a wrapper around scsi_build_sense_buffer() to format the buffer and set the correct SCSI status.

2021-05-31scsi: core: Stop using DRIVER_ERRORHannes Reinecke1-2/+5
Return the actual error code in __scsi_execute() (which, according to the documentation, should have happened anyway). And audit all callers to cope with negative return values from __scsi_execute() and friends.
