While working on IPv6 route replace I realized we can have a use-after-free in IPv4 in case the replaced route is offloaded and the only one using its FIB info. The problem is that fib_table_insert() drops the reference on the FIB info of the replaced routes which is eventually freed via call_rcu(). Since the driver doesn't hold a reference on this FIB info it can cause a use-after-free when it tries to clear the RTNH_F_OFFLOAD flag stored in fi->fib_flags. After running the following commands in a loop for enough time with a KASAN enabled kernel I finally got the below trace. $ ip route add 192.168.50.0/24 via 192.168.200.1 dev enp3s0np3 $ ip route replace 192.168.50.0/24 dev enp3s0np5 $ ip route del 192.168.50.0/24 dev enp3s0np5 BUG: KASAN: use-after-free in mlxsw_sp_fib_entry_offload_unset+0xa7/0x120 [mlxsw_spectrum] Read of size 4 at addr ffff8803717d9820 by task kworker/u4:2/55 [...] ? mlxsw_sp_fib_entry_offload_unset+0xa7/0x120 [mlxsw_spectrum] ? mlxsw_sp_fib_entry_offload_unset+0xa7/0x120 [mlxsw_spectrum] ? mlxsw_sp_router_neighs_update_work+0x1cd0/0x1ce0 [mlxsw_spectrum] ? mlxsw_sp_fib_entry_offload_unset+0xa7/0x120 [mlxsw_spectrum] __asan_load4+0x61/0x80 mlxsw_sp_fib_entry_offload_unset+0xa7/0x120 [mlxsw_spectrum] mlxsw_sp_fib_entry_offload_refresh+0xb6/0x370 [mlxsw_spectrum] mlxsw_sp_router_fib_event_work+0xd1c/0x2780 [mlxsw_spectrum] [...] Freed by task 5131: save_stack_trace+0x16/0x20 save_stack+0x46/0xd0 kasan_slab_free+0x70/0xc0 kfree+0x144/0x570 free_fib_info_rcu+0x2e7/0x410 rcu_process_callbacks+0x4f8/0xe30 __do_softirq+0x1d3/0x9e2 Fix this by taking a reference on the FIB info when creating the nexthop group it represents and drop it when the group is destroyed.

Since the introduction of ULD (Upper-Layer Drivers), the MSI-X deallocating path changed in cxgb4: the driver frees the interrupts of ULD when unregistering it or on shutdown PCI handler. Problem is that if a MSI-X is not freed before deallocated in the PCI layer, it will trigger a BUG() due to still "alive" interrupt being tentatively quiesced. The below trace was observed when doing a simple unbind of Chelsio's adapter PCI function, like: "echo 001e:80:00.4 > /sys/bus/pci/drivers/cxgb4/unbind" Trace: kernel BUG at drivers/pci/msi.c:352!

The PF driver sets up a list of firmware commands from the VF driver that needs to be forwarded to the PF for approval. This list is a 256-bit bitmap. The code that sets up the bitmap falls apart on big-endian architecture. __set_bit() does not work because it operates on long types whereas the firmware interface is defined in u32 types, causing bits in the wrong 32-bit word to be set. Fix it by setting the proper bits on an array of u32. Fixes: de68f5de ("bnxt_en: Fix bitmap declaration to work on 32-bit arches.")

When changing channels from combined to rx/tx or vice versa, the code uses the wrong "sh" parameter to determine if we are reserving rings for shared or non-shared mode. It should be using the ethtool requested "sh" parameter instead of the current "sh" parameter. Fix it by passing the "sh" parameter to bnxt_reserve_rings(). For ethtool, we will pass in the requested "sh" parameter. Fixes: 391be5c2 ("bnxt_en: Implement new scheme to reserve tx rings.")

.ndo_get_stats64() may not be protected by RTNL and can race with .ndo_stop() or other ethtool operations that can free the statistics memory. Fix it by setting a new flag BNXT_STATE_READ_STATS and then proceeding to read statistics memory only if the state is OPEN. The close path that frees the memory clears the OPEN state and then waits for the BNXT_STATE_READ_STATS to clear before proceeding to free the statistics memory.

Pull ARM updates from Russell King: - add support for ftrace-with-registers, which is needed for kgraft and other ftrace tools - support for mremap() for the sigpage/vDSO so that checkpoint/restore can work - add timestamps to each line of the register dump output - remove the unused KTHREAD_SIZE from nommu - align the ARM bitops APIs with the generic API (using unsigned long pointers rather than void pointers) - make the configuration of userspace Thumb support an expert option so that we can default it on, and avoid some hard to debug userspace crashes * 'for-linus' of git://git.armlinux.org.uk/~rmk/linux-arm: ARM: 8684/1: NOMMU: Remove unused KTHREAD_SIZE definition ARM: 8683/1: ARM32: Support mremap() for sigpage/vDSO ARM: 8679/1: bitops: Align prototypes to generic API ARM: 8678/1: ftrace: Adds support for CONFIG_DYNAMIC_FTRACE_WITH_REGS ARM: make configuration of userspace Thumb support an expert option ARM: 8673/1: Fix __show_regs output timestamps

Remove useless local variables _match_, _soc_ and the code related. Notice that const struct of_device_id of_mtk_match[] = { { .compatible = "mediatek,mt2701-eth" }, {}, }; So match->data is NULL.

As Hongjun/Nicolas summarized in their original patch: " When a device changes from one netns to another, it's first unregistered, then the netns reference is updated and the dev is registered in the new netns. Thus, when a slave moves to another netns, it is first unregistered. This triggers a NETDEV_UNREGISTER event which is caught by the bonding driver. The driver calls bond_release(), which calls dev_set_mtu() and thus triggers NETDEV_CHANGEMTU (the device is still in the old netns). " This is a very special case, because the device is being unregistered no one should still care about the NETDEV_CHANGEMTU event triggered at this point, we can avoid broadcasting this event on this path, and avoid touching inetdev_event()/addrconf_notify() path. It requires to export __dev_set_mtu() to bonding driver.
