2022-05-18net: af_key: check encryption module availability consistencyThomas Bartschies1-3/+3
Since the recent introduction supporting the SM3 and SM4 hash algos for IPsec, the kernel produces invalid pfkey acquire messages, when these encryption modules are disabled. This happens because the availability of the algos wasn't checked in all necessary functions. This patch adds these checks.

2022-05-18percpu_ref_init(): clean ->percpu_count_ref on failureAl Viro1-0/+1
That way percpu_ref_exit() is safe after failing percpu_ref_init(). At least one user (cgroup_create()) had a double-free that way; there might be other similar bugs. Easier to fix in percpu_ref_init(), rather than playing whack-a-mole in sloppy users... Usual symptoms look like a messed refcounting in one of subsystems that use percpu allocations (might be percpu-refcount, might be something else). Having refcounts for two different objects share memory is Not Nice(tm)... Reported-by: [email protected] Signed-off-by: Al Viro <[email protected]>

In case fw sync reset is called in parallel to device removal, device might stuck in the following deadlock: CPU 0 CPU 1 ----- ----- remove_one uninit_one (locks intf_state_mutex) mlx5_sync_reset_now_event() work in fw_reset->wq. mlx5_enter_error_state() mutex_lock (intf_state_mutex) cleanup_once fw_reset_cleanup() destroy_workqueue(fw_reset->wq) Drain the fw_reset WQ, and make sure no new work is being queued, before entering uninit_one().

2022-05-17net/mlx5e: Wrap mlx5e_trap_napi_poll into rcu_read_lockMaxim Mikityanskiy1-3/+10
The body of mlx5e_napi_poll is wrapped into rcu_read_lock to be able to read the XDP program pointer using rcu_dereference. However, the trap RQ NAPI doesn't use rcu_read_lock, because the trap RQ works only in the non-linear mode, and mlx5e_skb_from_cqe_nonlinear, until recently, didn't support XDP and didn't call rcu_dereference. Starting from the cited commit, mlx5e_skb_from_cqe_nonlinear supports XDP and calls rcu_dereference, but mlx5e_trap_napi_poll doesn't wrap it into rcu_read_lock. It leads to RCU-lockdep warnings like this: WARNING: suspicious RCU usage This commit fixes the issue by adding an rcu_read_lock to mlx5e_trap_napi_poll, similarly to mlx5e_napi_poll.

2022-05-17net/mlx5: DR, Ignore modify TTL on RX if device doesn't support itYevgeny Kliteynik2-21/+48
When modifying TTL, packet's csum has to be recalculated. Due to HW issue in ConnectX-5, csum recalculation for modify TTL on RX is supported through a work-around that is specifically enabled by configuration. If the work-around isn't enabled, rather than adding an unsupported action the modify TTL action on RX should be ignored. Ignoring modify TTL action might result in zero actions, so in such cases we will not convert the match STE to modify STE, as it is done by FW in DMFS. This patch fixes an issue where modify TTL action was ignored both on RX and TX instead of only on RX.

Unloading As a solution to fix use-after-free bugs, where we try to access these objects, when reading the value of flow_steering_mode devlink param[1], let's split flow steering creation and destruction into two routines: * init and cleanup: memory, cache, and pools allocation/free. * create and destroy: namespaces initialization and cleanup.

The root cause is that nci_skb_alloc with GFP_KERNEL parameter is called in st_nci_se_wt_timeout which is a timer handler.

2022-05-17net/qla3xxx: Fix a test in ql_reset_work()Christophe JAILLET1-1/+2
test_bit() tests if one bit is set or not. Here the logic seems to check of bit QL_RESET_PER_SCSI (i.e. 4) OR bit QL_RESET_START (i.e. 3) is set. In fact, it checks if bit 7 (4 | 3 = 7) is set, that is to say QL_ADAPTER_UP. This looks harmless, because this bit is likely be set, and when the ql_reset_work() delayed work is scheduled in ql3xxx_isr() (the only place that schedule this work), QL_RESET_START or QL_RESET_PER_SCSI is set. This has been spotted by smatch.

2022-05-17ice: Fix interrupt moderation settings getting clearedMichal Wilczynski2-11/+16
Adaptive-rx and Adaptive-tx are interrupt moderation settings that can be enabled/disabled using ethtool: ethtool -C ethX adaptive-rx on/off adaptive-tx on/off Unfortunately those settings are getting cleared after changing number of queues, or in ethtool world 'channels': ethtool -L ethX rx 1 tx 1 Clearing was happening due to introduction of bit fields in ice_ring_container struct. This way only itr_setting bits were rebuilt during ice_vsi_rebuild_set_coalesce(). Introduce an anonymous struct of bitfields and create a union to refer to them as a single variable. This way variable can be easily saved and restored.

2022-05-17ice: fix possible under reporting of ethtool Tx and Rx statisticsPaul Greenwalt1-3/+4
The hardware statistics counters are not cleared during resets so the drivers first access is to initialize the baseline and then subsequent reads are for reporting the counters. The statistics counters are read during the watchdog subtask when the interface is up. If the baseline is not initialized before the interface is up, then there can be a brief window in which some traffic can be transmitted/received before the initial baseline reading takes place. Directly initialize ethtool statistics in driver open so the baseline will be initialized when the interface is up, and any dropped packets incremented before the interface is up won't be reported.

2022-05-17net: vmxnet3: fix possible NULL pointer dereference in vmxnet3_rq_cleanup()Zixuan Fu1-0/+4
In vmxnet3_rq_create(), when dma_alloc_coherent() fails, vmxnet3_rq_destroy() is called. It sets rq->rx_ring[i].base to NULL. Then vmxnet3_rq_create() returns an error to its callers mxnet3_rq_create_all() -> vmxnet3_change_mtu(). Then vmxnet3_change_mtu() calls vmxnet3_force_close() -> dev_close() in error handling code. And the driver calls vmxnet3_close() -> vmxnet3_quiesce_dev() -> vmxnet3_rq_cleanup_all() -> vmxnet3_rq_cleanup(). In vmxnet3_rq_cleanup(), rq->rx_ring[ring_idx].base is accessed, but this variable is NULL, causing a NULL pointer dereference. To fix this possible bug, an if statement is added to check whether rq->rx_ring[0].base is NULL in vmxnet3_rq_cleanup() and exit early if so. The error log in our fault-injection testing is shown as follows: [ 65.220135] BUG: kernel NULL pointer dereference, address: 0000000000000008 ...

2022-05-17net: vmxnet3: fix possible use-after-free bugs in vmxnet3_rq_alloc_rx_buf()Zixuan Fu1-0/+2
In vmxnet3_rq_alloc_rx_buf(), when dma_map_single() fails, rbi->skb is freed immediately. Similarly, in another branch, when dma_map_page() fails, rbi->page is also freed. In the two cases, vmxnet3_rq_alloc_rx_buf() returns an error to its callers vmxnet3_rq_init() -> vmxnet3_rq_init_all() -> vmxnet3_activate_dev(). Then vmxnet3_activate_dev() calls vmxnet3_rq_cleanup_all() in error handling code, and rbi->skb or rbi->page are freed again in vmxnet3_rq_cleanup_all(), causing use-after-free bugs. To fix these possible bugs, rbi->skb and rbi->page should be cleared after they are freed.

2022-05-17xfrm: set dst dev to blackhole_netdev instead of loopback_dev in ifdownXin Long1-1/+1

Especially after commit faab39f63c1f ("net: allow out-of-order netdev unregistration"), it's no longer safe to use loopback_dev that may be freed before other netdev.

The following two scenarios were failing for lan966x. 1. If the port had the address X and then trying to assign the same address, then the HW was just removing this address because first it tries to learn new address and then delete the old one. As they are the same the HW remove it. 2. If the port eth0 was assigned the same address as one of the other ports eth1 then when assigning back the address to eth0 then the HW was deleting the address of eth1. The case 1. is fixed by checking if the port has already the same address while case 2. is fixed by checking if the address is used by any other port.

2022-05-16xfrm: fix "disable_policy" flag use when arriving from different devicesEyal Birger3-6/+32
In IPv4 setting the "disable_policy" flag on a device means no policy should be enforced for traffic originating from the device. This was implemented by seting the DST_NOPOLICY flag in the dst based on the originating device. However, dsts are cached in nexthops regardless of the originating devices, in which case, the DST_NOPOLICY flag value may be incorrect. Consider the following setup: +------------------------------+ | ROUTER | +-------------+ | +-----------------+ | | ipsec src |----|-|ipsec0 | | +-------------+ | |disable_policy=0 | +----+ | | +-----------------+ |eth1|-|----- +-------------+ | +-----------------+ +----+ | | noipsec src |----|-|eth0 | | +-------------+ | |disable_policy=1 | | | +-----------------+ | +------------------------------+ Where ROUTER has a default route towards eth1. dst entries for traffic arriving from eth0 would have DST_NOPOLICY and would be cached and therefore can be reused by traffic originating from ipsec0, skipping policy check. Fix by setting a IPSKB_NOPOLICY flag in IPCB and observing it instead of the DST in IN/FWD IPv4 policy checks.

This reordering broke BPF programs which relied on the old argument list.
