Commit 8a12f883 ("net: hso: fix null-ptr-deref during tty device unregistration") fixed the racy minor allocation reported by syzbot, but introduced an unconditional NULL-pointer dereference on every disconnect instead. Specifically, the serial device table must no longer be accessed after the minor has been released by hso_serial_tty_unregister().

Pablo Neira Ayuso says: ==================== Netfilter updates for net-next The following patchset contains Netfilter updates for net-next: 1) The various ip(6)table_foo incarnations are updated to expect that the table is passed as 'void *priv' argument that netfilter core passes to the hook functions. This reduces the struct net size by 2 cachelines on x86_64. From Florian Westphal. 2) Add cgroupsv2 support for nftables. 3) Fix bridge log family merge into nf_log_syslog: Missing unregistration from netns exit path, from Phil Sutter. 4) Add nft_pernet() helper to access nftables pernet area. 5) Add struct nfnl_info to reduce nfnetlink callback footprint and to facilite future updates.

The compat layer needs to parse untrusted input (the ruleset) to translate it to a 64bit compatible format. We had a number of bugs in this department in the past, so allow users to turn this feature off. Add CONFIG_NETFILTER_XTABLES_COMPAT kconfig knob and make it default to y to keep existing behaviour.

Michael Chan says: ==================== bnxt_en: Updates for net-next. This series includes these main enhancements: 1. Link related changes - add NRZ/PAM4 link signal mode to the link up message if known - rely on firmware to bring down the link during ifdown 2. SRIOV related changes - allow VF promiscuous mode if the VF is trusted - allow ndo operations to configure VF when the PF is ifdown - fix the scenario of the VF taking back control of it's MAC address - add Hyper-V VF device IDs 3. Support the option to transmit without FCS/CRC. 4. Implement .ndo_features_check() to disable offload when the UDP encap. packets are not supported. v2: Patch10: Reverse the check for supported UDP ports to be more straight forward. ==================== Signed-off-by: -

When the PF is no longer enforcing an assigned MAC address on a VF, the VF needs to call bnxt_approve_mac() to tell the PF what MAC address it is now using. Otherwise it gets out of sync and the PF won't know what MAC address the VF wants to use. Ultimately the VF will fail when it tries to setup the L2 MAC filter for the vnic. Reviewed-by:

Move it before bnxt_update_vf_mac(). In the next patch, we need to call bnxt_approve_mac() from bnxt_update_mac() under some conditions. This will avoid forward declaration. Reviewed-by:

It is perfectly legal for the stack to query and configure VFs via PF NDOs while the NIC is administratively down. Remove the unnecessary check for the PF to be in open state. Signed-off-by:

Edwin Peer authored
Firmware previously only allowed promiscuous mode for VFs associated with a default VLAN. It is now possible to enable promiscuous mode for a VF having no VLAN configured provided that it is trusted. In such cases the VF will see all packets received by the PF, irrespective of destination MAC or VLAN. Note, it is necessary to query firmware at the time of bnxt_promisc_ok() instead of in bnxt_hwrm_func_qcfg() because the trusted status might be altered by the PF after the VF has been configured. This check must now also be deferred because the firmware call sleeps. Signed-off-by:

In the current code, the driver will not shutdown the link during IFDOWN if there are still VFs sharing the port. Newer firmware will manage the link down decision when the port is shared by VFs, so we can just call firmware to shutdown the port unconditionally and let firmware make the final decision.

Copy the phy related feature flags from the firmware call HWRM_PORT_PHY_QCAPS to this new field. We can also remove the flags field in the bnxt_test_info structure. It's cleaner to have all PHY related flags in one location, directly copied from the firmware. To keep the BNXT_PHY_CFG_ABLE() macro logic the same, we need to make a slight adjustment to check that it is a PF. Reviewed-by:

The default behavior for source MACVLAN is to duplicate packets to appropriate type source devices, and then do the normal destination MACVLAN flow. This patch adds an option to skip destination MACVLAN processing if any matching source MACVLAN device has the option set. This allows setting up a "catch all" device for source MACVLAN: create one or more devices with type source nodst, and one device with e.g. type vepa, and incoming traffic will be received on exactly one device. v2: netdev wants non-standard line length Signed-off-by:

Saeed Mahameed says: ==================== mlx5-updates-2021-04-21 devlink external port attribute for SF (Sub-Function) port flavour This adds the support to instantiate Sub-Functions on external hosts E.g when Eswitch manager is enabled on the ARM SmarNic SoC CPU, users are now able to spawn new Sub-Functions on the Host server CPU. Parav Pandit Says: ================== This series introduces and uses external attribute for the SF port to indicate that a SF port belongs to an external controller. This is needed to generate unique phys_port_name when PF and SF numbers are overlapping between local and external controllers. For example two controllers 0 and 1, both of these controller have a SF. having PF number 0, SF number 77. Here, phys_port_name has duplicate entry which doesn't have controller number in it. Hence, add controller number optionally when a SF port is for an external controller. This extension is similar to existing PF and VF eswitch ports of the external controller. When a SF is for external controller an example view of external SF port and config sequence: On eswitch system: $ devlink dev eswitch set pci/0033:01:00.0 mode switchdev $ devlink port show pci/0033:01:00.0/196607: type eth netdev enP51p1s0f0np0 flavour physical port 0 splittable false pci/0033:01:00.0/131072: type eth netdev eth0 flavour pcipf controller 1 pfnum 0 external true splittable false function: hw_addr 00:00:00:00:00:00 $ devlink port add pci/0033:01:00.0 flavour pcisf pfnum 0 sfnum 77 controller 1 pci/0033:01:00.0/163840: type eth netdev eth1 flavour pcisf controller 1 pfnum 0 sfnum 77 splittable false function: hw_addr 00:00:00:00:00:00 state inactive opstate detached phys_port_name construction: $ cat /sys/class/net/eth1/phys_port_name c1pf0sf77 Patch summary: First 3 patches prepares the eswitch to handle vports in more generic way using xarray to lookup vport from its unique vport number.

This adds device tree probing to the IXP4xx ethernet driver. Add a platform data bool to tell us whether to register an MDIO bus for the device or not, as well as the corresponding NPE.

Florian Westphal authored
iptable_x modules rely on 'struct net' to contain a pointer to the table that should be evaluated. In order to remove these pointers from struct net, pass them via the 'priv' pointer in a similar fashion as nf_tables passes the rule data. To do that, duplicate the nf_hook_info array passed in from the iptable_x modules, update the ops->priv pointers of the copy to refer to the table and then change the hookfn implementations to just pass the 'priv' argument to the traverser. After this patch, the xt_table pointers can already be removed from struct net. However, changes to struct net result in re-compile of the entire network stack, so do the removal after arptables and ip6tables have been converted as well. Signed-off-by:

This changes how ip(6)table nat passes the ruleset/table to the evaluation loop. At the moment, it will fetch the table from struct net. This change stores the table in the hook_ops 'priv' argument instead. This requires to duplicate the hook_ops for each netns, so they can store the (per-net) xt_table structure. The dupliated nat hook_ops get stored in net_generic data area. They are free'd in the namespace exit path. This is a pre-requisite to remove the xt_table/ruleset pointers from struct net.

No need for these. There is only one caller, the xtables core, when the table is registered for the first time with a particular network namespace. After ->table_init() call, the table is linked into the tables[af] list, so next call to that function will skip the ->table_init(). Signed-off-by:
