If rndis_filter_open() fails, we need to remove the rndis device created in earlier steps, before returning an error code. Otherwise, the retry of netvsc_attach() from its callers will fail and hang. Fixes: 7b2ee50c ("hv_netvsc: common detach logic") Signed-off-by:

The devlink parameter "acl_region_rehash_interval" is a runtime parameter whose value is stored in a dynamically allocated memory. While reloading the driver, this memory is freed and then allocated again. A use-after-free might happen if during this time frame someone tries to retrieve its value. Since commit 070c63f2 ("net: devlink: allow to change namespaces during reload") the use-after-free can be reliably triggered when reloading the driver into a namespace, as after freeing the memory (via reload_down() callback) all the parameters are notified. Fix this by unpublishing and then re-publishing the parameters during reload. Fixes: 98bbf70c ("mlxsw: spectrum: add "acl_region_rehash_interval" devlink param") Fixes: 7c62cfb8 ("devlink: publish params only after driver init is done") Signed-off-by:

Current implementation for nvm_attr configuration instructs the management FW to load/unload the nvm-cfg image for each user-provided attribute in the input file. This consumes lot of cycles even for few tens of attributes. This patch updates the implementation to perform load/commit of the config for every 50 attributes. After loading the nvm-image, MFW expects that config should be committed in a predefined timer value (5 sec), hence it's not possible to write large number of attributes in a single load/commit window. Hence performing the commits in chunks. Fixes: 0dabbe1b ("qed: Add driver API for flashing the config attributes.") Signed-off-by:

After commit 0ce1822c ("vxlan: add adjacent link to limit depth level"), vxlan_changelink() could fail because of netdev_adjacent_change_prepare(). netdev_adjacent_change_prepare() returns -EEXIST when old lower device and new lower device are same. (old lower device is "dst->remote_dev" and new lower device is "lowerdev") So, before calling it, lowerdev should be NULL if these devices are same.

When a bonding interface is being created, it setups its mode and options. At that moment, it uses mode_lock so mode_lock should be initialized before that moment. rtnl_newlink() rtnl_create_link() alloc_netdev_mqs() ->setup() //bond_setup() ->newlink //bond_newlink bond_changelink() register_netdevice() ->ndo_init() //bond_init() After commit 089bca2c ("bonding: use dynamic lockdep key instead of subclass"), mode_lock is initialized in bond_init(). So in the bond_changelink(), un-initialized mode_lock can be used. mode_lock should be initialized in bond_setup().

Prior to this patch, the amount of counters guaranteed per VF in the resource tracker was MLX4_VF_COUNTERS_PER_PORT * MLX4_MAX_PORTS. It was set regardless if the VF was single or dual port. This caused several VFs to have no guaranteed counters although the system could satisfy their request. The fix is to dynamically guarantee counters, based on each VF specification.

Ethtool self test contains a test for link speed. This test reads the PTYS register and determines whether the current speed is valid or not. Change current implementation to use the function mlx5e_port_linkspeed() that does the same check and fails when speed is invalid. This code redundancy lead to a bug when mlx5e_port_linkspeed() was updated with expended speeds and the self test was not.

When CQE compression is enabled, compressed CQEs use the following structure: a title is followed by one or many blocks, each containing 8 mini CQEs (except the last, which may contain fewer mini CQEs). Due to NAPI budget restriction, a complete structure is not always parsed in one NAPI run, and some blocks with mini CQEs may be deferred to the next NAPI poll call - we have the mlx5e_decompress_cqes_cont call in the beginning of mlx5e_poll_rx_cq. However, if the budget is extremely low, some blocks may be left even after that, but the code that follows the mlx5e_decompress_cqes_cont call doesn't check it and assumes that a new CQE begins, which may not be the case. In such cases, random memory corruptions occur. An extremely low NAPI budget of 8 is used when busy_poll or busy_read is active. This commit adds a check to make sure that the previous compressed CQE has been completely parsed after mlx5e_decompress_cqes_cont, otherwise it prevents a new CQE from being fetched in the middle of a compressed CQE. This commit fixes random crashes in __build_skb, __page_pool_put_page and other not-related-directly places, that used to happen when both CQE compression and busy_poll/busy_read were enabled.

However, this leads to use-after-free error when initial filter that caused creation of new encap entry is deleted or when tunnel_key action is manually overwritten through action API. Moreover, with recent TC offloads API unlocking change struct flow_action_entry->tunnel point to temporal copy of tunnel info that is deallocated after filter is offloaded to hardware which causes bug to reproduce every time new filter is attached to existing encap entry with following KASAN bug: [ 314.885555] ================================================================== [ 314.886641] BUG: KASAN: use-after-free in memcmp+0x2c/0x60 [ 314.886864] Read of size 1 at addr ffff88886c746280 by task tc/2682 [ 314.887179] CPU: 22 PID: 2682 Comm: tc Not tainted 5.3.0-rc7+ #703 [ 314.887188] Hardware name: Supermicro SYS-2028TP-DECR/X10DRT-P, BIOS 2.0b 03/30/2017 [ 314.887195] Call Trace: [ 314.887215] dump_stack+0x9a/0xf0 [ 314.887236] print_address_description+0x67/0x323 [ 314.887248] ?

Vladimir Oltean says: ==================== VLAN fixes for Ocelot switch This series addresses 2 issues with vlan_filtering=1: - Untagged traffic gets dropped unless commands are run in a very specific order. - Untagged traffic starts being transmitted as tagged after adding another untagged VID on the port. Tested on NXP LS1028A-RDB board. ==================== Signed-off-by: -
Vladimir Oltean authored
The switch driver keeps a "vid" variable per port, which signifies _the_ VLAN ID that is stripped on that port's egress (aka the native VLAN on a trunk port). That is the way the hardware is designed (mostly). The port->vid is programmed into REW:PORT:PORT_VLAN_CFG:PORT_VID and the rewriter is told to send all traffic as tagged except the one having port->vid. There exists a possibility of finer-grained egress untagging decisions: using the VCAP IS1 engine, one rule can be added to match every VLAN-tagged frame whose VLAN should be untagged, and set POP_CNT=1 as action. However, the IS1 can hold at most 512 entries, and the VLANs are in the order of 6 * 4096. So the code is fine for now. But this sequence of commands: $ bridge vlan add dev swp0 vid 1 pvid untagged $ bridge vlan add dev swp0 vid 2 untagged makes untagged and pvid-tagged traffic be sent out of swp0 as tagged with VID 1, despite user's request. Prevent that from happening. The user should temporarily remove the existing untagged VLAN (1 in this case), add it back as tagged, and then add the new untagged VLAN (2 in this case).

Background information: the driver operates the hardware in a mode where a single VLAN can be transmitted as untagged on a particular egress port. That is the "native VLAN on trunk port" use case. Its value is held in port->vid. Consider the following command sequence (no network manager, all interfaces are down, debugging prints added by me): $ ip link add dev br0 type bridge vlan_filtering 1 $ ip link set dev swp0 master br0 Kernel code path during last command: br_add_slave -> ocelot_netdevice_port_event (NETDEV_CHANGEUPPER): [ 21.401901] ocelot_vlan_port_apply: port 0 vlan aware 0 pvid 0 vid 0 br_add_slave -> nbp_vlan_init -> switchdev_port_attr_set -> ocelot_port_attr_set (SWITCHDEV_ATTR_ID_BRIDGE_VLAN_FILTERING): [ 21.413335] ocelot_vlan_port_apply: port 0 vlan aware 1 pvid 0 vid 0 br_add_slave -> nbp_vlan_init -> nbp_vlan_add -> br_switchdev_port_vlan_add -> switchdev_port_obj_add -> ocelot_port_obj_add -> ocelot_vlan_vid_add [ 21.667421] ocelot_vlan_port_apply: port 0 vlan aware 1 pvid 1 vid 1 So far so good. The bridge has replaced the driver's default pvid used in standalone mode (0) with its own default_pvid (1). The port's vid (native VLAN) has also changed from 0 to 1. $ ip link set dev swp0 up [ 31.722956] 8021q: adding VLAN 0 to HW filter on device swp0 do_setlink -> dev_change_flags -> vlan_vid_add -> ocelot_vlan_rx_add_vid -> ocelot_vlan_vid_add: [ 31.728700] ocelot_vlan_port_apply: port 0 vlan aware 1 pvid 1 vid 0 The 8021q module uses the .ndo_vlan_rx_add_vid API on .ndo_open to make ports be able to transmit and receive 802.1p-tagged traffic by default. This API is supposed to offload a VLAN sub-interface, which for a switch port means to add a VLAN that is not a pvid, and tagged on egress. But the driver implementation of .ndo_vlan_rx_add_vid is wrong: it adds back vid 0 as "egress untagged". Now back to the initial paragraph: there is a single untagged VID that the driver keeps track of, and that has just changed from 1 (the pvid) to 0. So this breaks the bridge core's expectation, because it has changed vid 1 from untagged to tagged, when what the user sees is. $ bridge vlan port vlan ids swp0 1 PVID Egress Untagged br0 1 PVID Egress Untagged But curiously, instead of manifesting itself as "untagged and pvid-tagged traffic gets sent as tagged on egress", the bug: - is hidden when vlan_filtering=0 - manifests as dropped traffic when vlan_filtering=1, due to this setting: if (port->vlan_aware && !port->vid) /* If port is vlan-aware and tagged, drop untagged and priority * tagged frames. */ val |= ANA_PORT_DROP_CFG_DROP_UNTAGGED_ENA | ANA_PORT_DROP_CFG_DROP_PRIO_S_TAGGED_ENA | ANA_PORT_DROP_CFG_DROP_PRIO_C_TAGGED_ENA; which would have made sense if it weren't for this bug. The setting's intention was "this is a trunk port with no native VLAN, so don't accept untagged traffic". So the driver was never expecting to set VLAN 0 as the value of the native VLAN, 0 was just encoding for "invalid". So the fix is to not send 802.1p traffic as untagged, because that would change the port's native vlan to 0, unbeknownst to the bridge, and trigger unexpected code paths in the driver.

This results in a 'Trying to free already-free IRQ' warning. To solve the problem free_irq has been moved out of hip04_remove. Signed-off-by:

In the highly unlikely event that we fail to allocate either of the "/txrx" or "/control" workqueues, we should bail cleanly rather than blindly march on with NULL queue pointer(s) installed in the 'fjes_adapter' instance. Cc: "David S. Miller" <davem@davemloft.net> Reported-by:

lan78xx_status() will run with interrupts enabled due to the change in ed194d13 ("usb: core: remove local_irq_save() around ->complete() handler"). generic_handle_irq() expects to be run with IRQs disabled.
