Tony Nguyen says: ==================== ice bug fixes Alice Michael says: There were a couple of bugs that have been found and fixed by Anatolii in the ice driver. First he fixed a bug on ring creation by setting the default value for the teid. Anatolli also fixed a bug with deleting queues in ice_vc_dis_qs_msg based on their enablement. --- v2: Remove empty lines between tags The following are changes since commit 458f5d92: sfc: Do not free an empty page_ring and are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/net-queue 100GbE ==================== Link: https://lore.kernel.org/r/20220404183548.3422851-1-anthony.l.nguyen@intel.comSigned-off-by: Paolo Abeni <pabeni@redhat.com>

Disable check for queue being enabled in ice_vc_dis_qs_msg, because there could be a case when queues were created, but were not enabled. We still need to delete those queues. Normal workflow for VF looks like: Enable path: VIRTCHNL_OP_ADD_ETH_ADDR (opcode 10) VIRTCHNL_OP_CONFIG_VSI_QUEUES (opcode 6) VIRTCHNL_OP_ENABLE_QUEUES (opcode 8) Disable path: VIRTCHNL_OP_DISABLE_QUEUES (opcode 9) VIRTCHNL_OP_DEL_ETH_ADDR (opcode 11) The issue appears only in stress conditions when VF is enabled and disabled very fast. Eventually there will be a case, when queues are created by VIRTCHNL_OP_CONFIG_VSI_QUEUES, but are not enabled by VIRTCHNL_OP_ENABLE_QUEUES. In turn, these queues are not deleted by VIRTCHNL_OP_DISABLE_QUEUES, because there is a check whether queues are enabled in ice_vc_dis_qs_msg. When we bring up the VF again, we will see the "Failed to set LAN Tx queue context" error during VIRTCHNL_OP_CONFIG_VSI_QUEUES step. This happens because old 16 queues were not deleted and VF requests to create 16 more, but ice_sched_get_free_qparent in ice_ena_vsi_txq would fail to find a parent node for first newly requested queue (because all nodes are allocated to 16 old queues). Testing Hints: Just enable and disable VF fast enough, so it would be disabled before reaching VIRTCHNL_OP_ENABLE_QUEUES. while true; do ip link set dev ens785f0v0 up sleep 0.065 # adjust delay value for you machine ip link set dev ens785f0v0 down done Fixes: 77ca27c4 ("ice: add support for virtchnl_queue_select.[tx|rx]_queues bitmap") Signed-off-by: Anatolii Gerasymenko <anatolii.gerasymenko@intel.com> Tested-by: Konrad Jankowski <konrad0.jankowski@intel.com> Signed-off-by: Alice Michael <alice.michael@intel.com> Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.com> Signed-off-by: Paolo Abeni <pabeni@redhat.com>

When VF is freshly created, but not brought up, ring->txq_teid value is by default set to 0. But 0 is a valid TEID. On some platforms the Root Node of Tx scheduler has a TEID = 0. This can cause issues as shown below. The proper way is to set ring->txq_teid to ICE_INVAL_TEID (0xFFFFFFFF). Testing Hints: echo 1 > /sys/class/net/ens785f0/device/sriov_numvfs ip link set dev ens785f0v0 up ip link set dev ens785f0v0 down If we have freshly created VF and quickly turn it on and off, so there would be no time to reach VIRTCHNL_OP_CONFIG_VSI_QUEUES stage, then VIRTCHNL_OP_DISABLE_QUEUES stage will fail with error: [ 639.531454] disable queue 89 failed 14 [ 639.532233] Failed to disable LAN Tx queues, error: ICE_ERR_AQ_ERROR [ 639.533107] ice 0000:02:00.0: Failed to stop Tx ring 0 on VSI 5 The reason for the fail is that we are trying to send AQ command to delete queue 89, which has never been created and receive an "invalid argument" error from firmware. As this queue has never been created, it's teid and ring->txq_teid have default value 0. ice_dis_vsi_txq has a check against non-existent queues: node = ice_sched_find_node_by_teid(pi->root, q_teids[i]); if (!node) continue; But on some platforms the Root Node of Tx scheduler has a teid = 0. Hence, ice_sched_find_node_by_teid finds a node with teid = 0 (it is pi->root), and we go further to submit an erroneous request to firmware.

Michael Chan says: ==================== bnxt_en: XDP redirect fixes This series includes 3 fixes related to the XDP redirect code path in the driver. The first one adds locking when the number of TX XDP rings is less than the number of CPUs. The second one adjusts the maximum MTU that can support XDP with enough tail room in the buffer. The 3rd one fixes a race condition between TX ring shutdown and the XDP redirect path. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

Ray Jui authored
Add checks in the XDP redirect callback to prevent XDP from running when the TX ring is undergoing shutdown. Also remove redundant checks in the XDP redirect callback to validate the txr and the flag that indicates the ring supports XDP. The modulo arithmetic on 'tx_nr_rings_xdp' already guarantees the derived TX ring is an XDP ring. txr is also guaranteed to be valid after checking BNXT_STATE_OPEN and within RCU grace period.

When the PHY and the MAC are capable of doing timestamping, the PHY has priority. Therefore the DT option lan8814,ignore-ts was added such that the PHY will not expose a PHC so then the timestamping was done in the MAC.

In commit 9cbadf09 ("net: stmmac: support max-speed device tree property"), when DT platforms don't set "max-speed", max_speed is set to -1; for non-DT platforms, it stays the default 0. Prior to commit eeef2f6b ("net: stmmac: Start adding phylink support"), the check for a valid max_speed setting was to check if it was greater than zero. This commit got it right, but subsequent patches just checked for non-zero, which is incorrect for DT platforms. In commit 92c3807b ("net: stmmac: convert to phylink_get_linkmodes()") the conversion switched completely to checking for non-zero value as a valid value, which caused 1000base-T to stop getting advertised by default. Instead of trying to fix all the checks, simply leave max_speed alone if DT property parsing fails.

Nikolay Aleksandrov says: ==================== net: ipv4: fix nexthop route delete warning The first patch fixes a warning that can be triggered by deleting a nexthop route and specifying a device (more info in its commit msg). And the second patch adds a selftest for that case. Chose this way to fix it because we should match when deleting without nh spec and should fail when deleting a nexthop route with old-style nh spec because nexthop objects are managed separately, e.g.: $ ip r show 1.2.3.4/32 1.2.3.4 nhid 12 via 192.168.11.2 dev dummy0 $ ip r del 1.2.3.4/32 $ ip r del 1.2.3.4/32 nhid 12 <both should work> $ ip r del 1.2.3.4/32 dev dummy0 <should fail with ESRCH> v2: addded more to patch 01's commit message adjusted the test comment in patch 02 ==================== Signed-off-by: David S.

Add a test which causes a WARNING on kernels which treat a nexthop route like a normal route when comparing for deletion and a device is specified. That is, a route is found but we hit a warning while matching it. The warning is from fib_info_nh() in include/net/nexthop.h because we run it on a fib_info with nexthop object. The call chain is: inet_rtm_delroute -> fib_table_delete -> fib_nh_match (called with a nexthop fib_info and also with fc_oif set thus calling fib_info_nh on the fib_info and triggering the warning). Repro steps: $ ip nexthop add id 12 via 172.16.1.3 dev veth1 $ ip route add 172.16.101.1/32 nhid 12 $ ip route delete 172.16.101.1/32 dev veth1 Signed-off-by: Nikolay Aleksandrov <razor@blackwall.org> Reviewed-by: David Ahern <dsahern@kernel.org> Signed-off-by: David S.

FRR folks have hit a kernel warning[1] while deleting routes[2] which is caused by trying to delete a route pointing to a nexthop id without specifying nhid but matching on an interface. That is, a route is found but we hit a warning while matching it. The warning is from fib_info_nh() in include/net/nexthop.h because we run it on a fib_info with nexthop object. The call chain is: inet_rtm_delroute -> fib_table_delete -> fib_nh_match (called with a nexthop fib_info and also with fc_oif set thus calling fib_info_nh on the fib_info and triggering the warning).

Handling of all-multicast flag and associated multicast promiscuous mode is broken in ice driver. When an user switches allmulticast flag on or off the driver checks whether any VLANs are configured over the interface (except default VLAN 0). If any extra VLANs are registered it enables multicast promiscuous mode for all these VLANs (including default VLAN 0) using ICE_SW_LKUP_PROMISC_VLAN look-up type. In this situation all multicast packets tagged with known VLAN ID or untagged are received and multicast packets tagged with unknown VLAN ID ignored. If no extra VLANs are registered (so only VLAN 0 exists) it enables multicast promiscuous mode for VLAN 0 and uses ICE_SW_LKUP_PROMISC look-up type. In this situation any multicast packets including tagged ones are received. The driver handles IFF_ALLMULTI in ice_vsi_sync_fltr() this way: ice_vsi_sync_fltr() { ... if (changed_flags & IFF_ALLMULTI) { if (netdev->flags & IFF_ALLMULTI) { if (vsi->num_vlans > 1) ice_set_promisc(..., ICE_MCAST_VLAN_PROMISC_BITS); else ice_set_promisc(..., ICE_MCAST_PROMISC_BITS); } else { if (vsi->num_vlans > 1) ice_clear_promisc(..., ICE_MCAST_VLAN_PROMISC_BITS); else ice_clear_promisc(..., ICE_MCAST_PROMISC_BITS); } } ... } The code above depends on value vsi->num_vlan that specifies number of VLANs configured over the interface (including VLAN 0) and this is problem because that value is modified in NDO callbacks ice_vlan_rx_add_vid() and ice_vlan_rx_kill_vid(). Scenario 1: 1. ip link set ens7f0 allmulticast on 2. ip link add vlan10 link ens7f0 type vlan id 10 3. ip link set ens7f0 allmulticast off 4. ip link set ens7f0 allmulticast on [1] In this scenario IFF_ALLMULTI is enabled and the driver calls ice_set_promisc(..., ICE_MCAST_PROMISC_BITS) that installs multicast promisc rule with non-VLAN look-up type. [2] Then VLAN with ID 10 is added and vsi->num_vlan incremented to 2 [3] Command switches IFF_ALLMULTI off and the driver calls ice_clear_promisc(..., ICE_MCAST_VLAN_PROMISC_BITS) but this call is effectively NOP because it looks for multicast promisc rules for VLAN 0 and VLAN 10 with VLAN look-up type but no such rules exist. So the all-multicast remains enabled silently in hardware. [4] Command tries to switch IFF_ALLMULTI on and the driver calls ice_clear_promisc(..., ICE_MCAST_PROMISC_BITS) but this call fails (-EEXIST) because non-VLAN multicast promisc rule already exists. Scenario 2: 1. ip link add vlan10 link ens7f0 type vlan id 10 2. ip link set ens7f0 allmulticast on 3. ip link add vlan20 link ens7f0 type vlan id 20 4. ip link del vlan10 ; ip link del vlan20 5. ip link set ens7f0 allmulticast off [1] VLAN with ID 10 is added and vsi->num_vlan==2 [2] Command switches IFF_ALLMULTI on and driver installs multicast promisc rules with VLAN look-up type for VLAN 0 and 10 [3] VLAN with ID 20 is added and vsi->num_vlan==3 but no multicast promisc rules is added for this new VLAN so the interface does not receive MC packets from VLAN 20 [4] Both VLANs are removed but multicast rule for VLAN 10 remains installed so interface receives multicast packets from VLAN 10 [5] Command switches IFF_ALLMULTI off and because vsi->num_vlan is 1 the driver tries to remove multicast promisc rule for VLAN 0 with non-VLAN look-up that does not exist. All-multicast looks disabled from user point of view but it is partially enabled in HW (interface receives all multicast packets either untagged or tagged with VLAN ID 10) To resolve these issues the patch introduces these changes: 1. Adds handling for IFF_ALLMULTI to ice_vlan_rx_add_vid() and ice_vlan_rx_kill_vid() callbacks. So when VLAN is added/removed and IFF_ALLMULTI is enabled an appropriate multicast promisc rule for that VLAN ID is added/removed. 2. In ice_vlan_rx_add_vid() when first VLAN besides VLAN 0 is added so (vsi->num_vlan == 2) and IFF_ALLMULTI is enabled then look-up type for existing multicast promisc rule for VLAN 0 is updated to ICE_MCAST_VLAN_PROMISC_BITS. 3. In ice_vlan_rx_kill_vid() when last VLAN besides VLAN 0 is removed so (vsi->num_vlan == 1) and IFF_ALLMULTI is enabled then look-up type for existing multicast promisc rule for VLAN 0 is updated to ICE_MCAST_PROMISC_BITS. 4. Both ice_vlan_rx_{add,kill}_vid() have to run under ICE_CFG_BUSY bit protection to avoid races with ice_vsi_sync_fltr() that runs in ice_service_task() context. 5. Bit ICE_VSI_VLAN_FLTR_CHANGED is use-less and can be removed. 6. Error messages added to ice_fltr_*_vsi_promisc() helper functions to avoid them in their callers 7.

Commit 2ccc1c1c ("ice: Remove excess error variables") merged the usage of 'status' and 'err' variables into single one in function ice_set_mac_address(). Unfortunately this causes a regression when call of ice_fltr_add_mac() returns -EEXIST because this return value does not indicate an error in this case but value of 'err' remains to be -EEXIST till the end of the function and is returned to caller. Prior mentioned commit this does not happen because return value of ice_fltr_add_mac() was stored to 'status' variable first and if it was -EEXIST then 'err' remains to be zero. Fix the problem by reset 'err' to zero when ice_fltr_add_mac() returns -EEXIST.

VSI is set as default forwarding one when promisc mode is set for PF interface, when PF is switched to switchdev mode or when VF driver asks to enable allmulticast or promisc mode for the VF interface (when vf-true-promisc-support priv flag is off). The third case is buggy because in that case VSI associated with VF remains as default one after VF removal. Reproducer: 1. Create VF echo 1 > sys/class/net/ens7f0/device/sriov_numvfs 2. Enable allmulticast or promisc mode on VF ip link set ens7f0v0 allmulticast on ip link set ens7f0v0 promisc on 3. Delete VF echo 0 > sys/class/net/ens7f0/device/sriov_numvfs 4. Try to enable promisc mode on PF ip link set ens7f0 promisc on Although it looks that promisc mode on PF is enabled the opposite is true because ice_vsi_sync_fltr() responsible for IFF_PROMISC handling first checks if any other VSI is set as default forwarding one and if so the function does not do anything. At this point it is not possible to enable promisc mode on PF without re-probe device. To resolve the issue this patch clear default forwarding VSI during ice_vsi_release() when the VSI to be released is the default one.

This reverts commit a1ff94c2. Switch drivers that don't implement ->port_change_mtu() will cause the DSA master to remain with an MTU of 1500, since we've deleted the other code path. In turn, this causes a regression for those systems, where MTU-sized traffic can no longer be terminated. Revert the change taking into account the fact that rtnl_lock() is now taken top-level from the callers of dsa_master_setup() and dsa_master_teardown(). Also add a comment in order for it to be absolutely clear why it is still needed.

Fix a use-after-free when using page_pool with page fragments. We encountered this problem during normal RX in the hns3 driver: (1) Initially we have three descriptors in the RX queue. The first one allocates PAGE1 through page_pool, and the other two allocate one half of PAGE2 each. Page references look like this: RX_BD1 _______ PAGE1 RX_BD2 _______ PAGE2 RX_BD3 _________/ (2) Handle RX on the first descriptor. Allocate SKB1, eventually added to the receive queue by tcp_queue_rcv(). (3) Handle RX on the second descriptor. Allocate SKB2 and pass it to netif_receive_skb(): netif_receive_skb(SKB2) ip_rcv(SKB2) SKB3 = skb_clone(SKB2) SKB2 and SKB3 share a reference to PAGE2 through skb_shinfo()->dataref. The other ref to PAGE2 is still held by RX_BD3: SKB2 ---+- PAGE2 SKB3 __/ / RX_BD3 _________/ (3b) Now while handling TCP, coalesce SKB3 with SKB1: tcp_v4_rcv(SKB3) tcp_try_coalesce(to=SKB1, from=SKB3) // succeeds kfree_skb_partial(SKB3) skb_release_data(SKB3) // drops one dataref SKB1 _____ PAGE1 \____ SKB2 _____ PAGE2 / RX_BD3 _________/ In skb_try_coalesce(), __skb_frag_ref() takes a page reference to PAGE2, where it should instead have increased the page_pool frag reference, pp_frag_count. Without coalescing, when releasing both SKB2 and SKB3, a single reference to PAGE2 would be dropped. Now when releasing SKB1 and SKB2, two references to PAGE2 will be dropped, resulting in underflow. (3c) Drop SKB2: af_packet_rcv(SKB2) consume_skb(SKB2) skb_release_data(SKB2) // drops second dataref page_pool_return_skb_page(PAGE2) // drops one pp_frag_count SKB1 _____ PAGE1 \____ PAGE2 / RX_BD3 _________/ (4) Userspace calls recvmsg() Copies SKB1 and releases it. Since SKB3 was coalesced with SKB1, we release the SKB3 page as well: tcp_eat_recv_skb(SKB1) skb_release_data(SKB1) page_pool_return_skb_page(PAGE1) page_pool_return_skb_page(PAGE2) // drops second pp_frag_count (5) PAGE2 is freed, but the third RX descriptor was still using it! In our case this causes IOMMU faults, but it would silently corrupt memory if the IOMMU was disabled. Change the logic that checks whether pp_recycle SKBs can be coalesced. We still reject differing pp_recycle between 'from' and 'to' SKBs, but in order to avoid the situation described above, we also reject coalescing when both 'from' and 'to' are pp_recycled and 'from' is cloned. The new logic allows coalescing a cloned pp_recycle SKB into a page refcounted one, because in this case the release (4) will drop the right reference, the one taken by skb_try_coalesce().

in commit 04893908 ("vrf: add mac header for tunneled packets when sniffer is attached") an Ethernet header was cooked for traffic originating from tunnel devices. However, the header is added based on whether the mac_header is unset and ignores cases where the device doesn't expose a mac header to upper layers, such as in ip tunnels like ipip and gre. Traffic originating from such devices still appears garbled when capturing on the vrf device. Fix by observing whether the original device exposes a header to upper layers, similar to the logic done in af_packet. In addition, skb->mac_len needs to be adjusted after adding the Ethernet header for the skb_push/pull() surrounding dev_queue_xmit_nit() to work on these packets.

So memcpy() require 16 bytes from 12 bytes memory space will trigger slab-out-of-bounds bug as following: ================================================================== BUG: KASAN: slab-out-of-bounds in decrypt_internal+0x385/0xc40 [tls] Read of size 16 at addr ffff888114e84e60 by task tls/10911 Call Trace: <TASK> dump_stack_lvl+0x34/0x44 print_report.cold+0x5e/0x5db ? decrypt_internal+0x385/0xc40 [tls] kasan_report+0xab/0x120 ? decrypt_internal+0x385/0xc40 [tls] kasan_check_range+0xf9/0x1e0 memcpy+0x20/0x60 decrypt_internal+0x385/0xc40 [tls] ? tls_get_rec+0x2e0/0x2e0 [tls] ? process_rx_list+0x1a5/0x420 [tls] ? tls_setup_from_iter.constprop.0+0x2e0/0x2e0 [tls] decrypt_skb_update+0x9d/0x400 [tls] tls_sw_recvmsg+0x3c8/0xb50 [tls] Allocated by task 10911: kasan_save_stack+0x1e/0x40 __kasan_kmalloc+0x81/0xa0 tls_set_sw_offload+0x2eb/0xa20 [tls] tls_setsockopt+0x68c/0x700 [tls] __sys_setsockopt+0xfe/0x1b0 Replace the crypto_aead_ivsize() with prot->iv_size + prot->salt_size when memcpy() iv value in TLS_1_3_VERSION scenario.

After rx/tx ring buffer size is changed, kernel panic occurs when it acts XDP_TX or XDP_REDIRECT. When tx/rx ring buffer size is changed(ethtool -G), sfc driver reallocates and reinitializes rx and tx queues and their buffer (tx_queue->buffer). But it misses reinitializing xdp queues(efx->xdp_tx_queues). So, while it is acting XDP_TX or XDP_REDIRECT, it uses the uninitialized tx_queue->buffer. A new function efx_set_xdp_channels() is separated from efx_set_channels() to handle only xdp queues. Splat looks like: BUG: kernel NULL pointer dereference, address: 000000000000002a #PF: supervisor write access in kernel mode #PF: error_code(0x0002) - not-present page PGD 0 P4D 0 Oops: 0002 [#4] PREEMPT SMP NOPTI RIP: 0010:efx_tx_map_chunk+0x54/0x90 [sfc] CPU: 2 PID: 0 Comm: swapper/2 Tainted: G D 5.17.0+ #55 e8beeee8289528f11357029357cf Code: 48 8b 8d a8 01 00 00 48 8d 14 52 4c 8d 2c d0 44 89 e0 48 85 c9 74 0e 44 89 e2 4c 89 f6 48 80 RSP: 0018:ffff92f121e45c60 EFLAGS: 00010297 RIP: 0010:efx_tx_map_chunk+0x54/0x90 [sfc] RAX: 0000000000000040 RBX: ffff92ea506895c0 RCX: ffffffffc0330870 RDX: 0000000000000001 RSI: 00000001139b10ce RDI: ffff92ea506895c0 RBP: ffffffffc0358a80 R08: 00000001139b110d R09: 0000000000000000 R10: 0000000000000001 R11: ffff92ea414c0088 R12: 0000000000000040 R13: 0000000000000018 R14: 00000001139b10ce R15: ffff92ea506895c0 FS: 0000000000000000(0000) GS:ffff92f121ec0000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 Code: 48 8b 8d a8 01 00 00 48 8d 14 52 4c 8d 2c d0 44 89 e0 48 85 c9 74 0e 44 89 e2 4c 89 f6 48 80 CR2: 000000000000002a CR3: 00000003e6810004 CR4: 00000000007706e0 RSP: 0018:ffff92f121e85c60 EFLAGS: 00010297 PKRU: 55555554 RAX: 0000000000000040 RBX: ffff92ea50689700 RCX: ffffffffc0330870 RDX: 0000000000000001 RSI: 00000001145a90ce RDI: ffff92ea50689700 RBP: ffffffffc0358a80 R08: 00000001145a910d R09: 0000000000000000 R10: 0000000000000001 R11: ffff92ea414c0088 R12: 0000000000000040 R13: 0000000000000018 R14: 00000001145a90ce R15: ffff92ea50689700 FS: 0000000000000000(0000) GS:ffff92f121e80000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 000000000000002a CR3: 00000003e6810005 CR4: 00000000007706e0 PKRU: 55555554 Call Trace: <IRQ> efx_xdp_tx_buffers+0x12b/0x3d0 [sfc 84c94b8e32d44d296c17e10a634d3ad454de4ba5] __efx_rx_packet+0x5c3/0x930 [sfc 84c94b8e32d44d296c17e10a634d3ad454de4ba5] efx_rx_packet+0x28c/0x2e0 [sfc 84c94b8e32d44d296c17e10a634d3ad454de4ba5] efx_ef10_ev_process+0x5f8/0xf40 [sfc 84c94b8e32d44d296c17e10a634d3ad454de4ba5] ? enqueue_task_fair+0x95/0x550 efx_poll+0xc4/0x360 [sfc 84c94b8e32d44d296c17e10a634d3ad454de4ba5] Fixes: 3990a8ff ("sfc: allocate channels for XDP tx queues") Signed-off-by: Taehee Yoo <ap420073@gmail.com> Signed-off-by: David S.
