2021-06-01net/mlx5: DR, Create multi-destination flow table with level less than 64Yevgeny Kliteynik
Flow table that contains flow pointing to multiple flow tables or multiple TIRs must have a level lower than 64. In our case it applies to muli- destination flow table. Fix the level of the created table to comply with HW Spec definitions, and still make sure that its level lower than SW-owned tables, so that it would be possible to point from the multi-destination FW table to SW tables.

2021-06-01net: ethernet: rmnet: Add support for MAPv5 egress packetsSharath Chandra Vurukala
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.

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 Sukholitko
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 Mikityanskiy
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 Sassu
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.

2021-06-01KVM: arm64: vgic: Let an interrupt controller advertise lack of HW deactivationMarc Zyngier

However, some implementations have choosen not to implement this, meaning that we will need some unsavoury workarounds to deal with this.

2021-05-31mac80211: Fix NULL ptr deref for injected rate infoMathy Vanhoef
The commit cb17ed29a7a5 ("mac80211: parse radiotap header when selecting Tx queue") moved the code to validate the radiotap header from ieee80211_monitor_start_xmit to ieee80211_parse_tx_radiotap. This made is possible to share more code with the new Tx queue selection code for injected frames. But at the same time, it now required the call of ieee80211_parse_tx_radiotap at the beginning of functions which wanted to handle the radiotap header. And this broke the rate parser for radiotap header parser. The radiotap parser for rates is operating most of the time only on the data in the actual radiotap header. But for the 802.11a/b/g rates, it must also know the selected band from the chandef information. But this information is only written to the ieee80211_tx_info at the end of the ieee80211_monitor_start_xmit - long after ieee80211_parse_tx_radiotap was already called. The info->band information was therefore always 0 (NL80211_BAND_2GHZ) when the parser code tried to access it. For a 5GHz only device, injecting a frame with 802.11a rates would cause a NULL pointer dereference because local->hw.wiphy->bands[NL80211_BAND_2GHZ] would most likely have been NULL when the radiotap parser searched for the correct rate index of the driver.
