Jakub Kicinski says: ==================== net: fix netpoll crash with bnxt Rob run into crashes when using XDP on bnxt. Upon investigation it turns out that during driver reconfig irq core produces a warning message when IRQs are requested. This triggers netpoll, which in turn accesses uninitialized driver state. Same crash can also be triggered on this platform by changing the number of rings. Looks like we have two missing pieces here, netif_napi_add() has to make sure we start out with netpoll blocked. The driver also has to be more careful about when napi gets enabled. Tested XDP and channel count changes, the warning message no longer causes a crash. Not sure if the memory barriers added in patch 1 are necessary, but it seems we should have them. ==================== Signed-off-by:

Netpoll can try to poll napi as soon as napi_enable() is called.

napi_disable() makes sure to set the NAPI_STATE_NPSVC bit to prevent netpoll from accessing rings before init is complete. However, the same is not done for fresh napi instances in netif_napi_add(), even though we expect NAPI instances to be added as disabled. This causes crashes during driver reconfiguration (enabling XDP, changing the channel count) - if there is any printk() after netif_napi_add() but before napi_enable(). To ensure memory ordering is correct we need to use RCU accessors. Reported-by:

fib_info_notify_update() is always called with RTNL held, but not from an RCU read-side critical section. This leads to the following warning [1] when the FIB table list is traversed with hlist_for_each_entry_rcu(), but without a proper lockdep expression. Since modification of the list is protected by RTNL, silence the warning by adding a lockdep expression which verifies RTNL is held.

Set the skb's network_header before it is passed to the underlying Ethernet device for transmission. This patch fixes the following issue: When we use this driver with AF_PACKET sockets, there would be error messages of: protocol 0805 is buggy, dev (Ethernet interface name) printed in the system "dmesg" log. This is because skbs passed down to the Ethernet device for transmission don't have their network_header properly set, and the dev_queue_xmit_nit function in net/core/dev.c complains about this. Reason of setting the network_header to this place (at the end of the Ethernet header, and at the beginning of the Ethernet payload): Because when this driver receives an skb from the Ethernet device, the network_header is also set at this place.

Since commit 9c66d156 ("taprio: Add support for hardware offloading") there's a bit of inconsistency when offloading schedules to the hardware: In software mode, the gate masks are specified in terms of traffic classes, so if say "sched-entry S 03 20000", it means that the traffic classes 0 and 1 are open for 20us; when taprio is offloaded to hardware, the gate masks are specified in terms of hardware queues. The idea here is to fix hardware offloading, so schedules in hardware and software mode have the same behavior. What's needed to do is to map traffic classes to queues when applying the offload to the driver. Fixes: 9c66d156 ("taprio: Add support for hardware offloading") Signed-off-by:

Michael Chan authored
The recent changes to support user-defined RSS map assume that RX rings are always reserved and the default RSS map is set after the RX rings are successfully reserved. If the firmware spec is older than 1.6.1, no ring reservations are required and the default RSS map is not setup at all. In another scenario where the fw Resource Manager is older, RX rings are not reserved and we also end up with no valid RSS map. Fix both issues in bnxt_need_reserve_rings(). In both scenarios described above, we don't need to reserve RX rings so we need to call this new function bnxt_check_rss_map_no_rmgr() to setup the default RSS map when needed. Without valid RSS map, the NIC won't receive packets properly. Fixes: 1667cbf6 ("bnxt_en: Add logical RSS indirection table structure.") Reviewed-by:

There are no VF rings available during probe when the device is configured using the Minimal-Static reservation strategy. In this case, the RSS indirection table can only be initialized later, during bnxt_open_nic(). However, this was not happening because the rings will already have been reserved via bnxt_init_dflt_ring_mode(), causing bnxt_need_reserve_rings() to return false in bnxt_reserve_rings() and bypass the RSS table init. Solve this by pushing the call to bnxt_set_dflt_rss_indir_tbl() into __bnxt_reserve_rings(), which is common to both paths and is called whenever ring configuration is changed. After doing this, the RSS table init that must be called from bnxt_init_one() happens implicitly via bnxt_set_default_rings(), necessitating doing the allocation earlier in order to avoid a null pointer dereference.

Firmware returns RESOURCE_ACCESS_DENIED for HWRM_TEMP_MONITORY_QUERY for VFs. This produces unpleasing error messages in the log when temp1_input is queried via the hwmon sysfs interface from a VF. The error is harmless and expected, so silence it and return unknown as the value. Since the device temperature is not particularly sensitive information, provide flexibility to change this policy in future by silencing the error rather than avoiding the HWRM call entirely for VFs.

bnxt_fw_reset_task() is run from a delayed workqueue. The current code is not cancelling the workqueue in the driver's .remove() method and it can potentially crash if the device is removed with the workqueue still pending. The fix is to clear the BNXT_STATE_IN_FW_RESET flag and then cancel the delayed workqueue in bnxt_remove_one(). bnxt_queue_fw_reset_work() also needs to check that this flag is set before scheduling. This will guarantee that no rescheduling will be done after it is cancelled. Fixes: 230d1f0d ("bnxt_en: Handle firmware reset.") Reviewed-by:

We are returning the wrong count for ETH_SS_STATS in get_sset_count() when XDP or TCs are enabled. In a recent commit, we got rid of irrelevant counters when the ring is RX only or TX only, but we did not make the proper adjustments for the count. As a result, when we have XDP or TCs enabled, we are returning an excess count because some of the rings are TX only. This causes ethtool -S to display extra counters with no counter names. Fix bnxt_get_num_ring_stats() by not assuming that all rings will always have RX and TX counters in combined mode.

At the time of do_rest, ibmvnic tries to re-initalize the tx_pools and rx_pools to avoid re-allocating the long term buffer. However there is a window inside do_reset that the tx_pools and rx_pools were freed before re-initialized making it possible to deference null pointers. This patch fix this issue by always check the tx_pool and rx_pool are not NULL after ibmvnic_login. If so, re-allocating the pools. This will avoid getting into calling reset_tx/rx_pools with NULL adapter tx_pools/rx_pools pointer. Also add null pointer check in reset_tx_pools and reset_rx_pools to safe handle NULL pointer case.

Clang warns: drivers/net/dsa/sja1105/sja1105_main.c:3418:38: warning: address of array 'match->compatible' will always evaluate to 'true' [-Wpointer-bool-conversion] for (match = sja1105_dt_ids; match->compatible; match++) { ~~~ ~~~~~~~^~~~~~~~~~ 1 warning generated. We should check the value of the first character in compatible to see if it is empty or not. This matches how the rest of the tree iterates over IDs.
