So far Linux supported only two levels of MTD devices so we didn't need a very precise description for this sysfs file. With commit 97519dc5 ("mtd: partitions: add support for subpartitions") there is support for a tree structure so we should have more precise description. Using "parent" and "flash device" makes it more accurate. Signed-off-by:

I made the mistake of upgrading my desktop to the new Fedora 26 that comes with gcc-7.1.1. There's nothing wrong per se that I've noticed, but I now have 1500 lines of warnings, mostly from the new format-truncation warning triggering all over the tree. We use 'snprintf()' and friends in a lot of places, and often know that the numbers are fairly small (ie a controller index or similar), but gcc doesn't know that, and sees an 'int', and thinks that it could be some huge number. And then complains when our buffers are not able to fit the name for the ten millionth controller. These warnings aren't necessarily bad per se, and we probably want to look through them subsystem by subsystem, but at least during the merge window they just mean that I can't even see if somebody is introducing any *real* problems when I pull. So warnings disabled for now. Signed-off-by:

If we have more than 32 unicast MAC addresses assigned to an interface we will read beyond the end of the address table in the driver when adding filters. The next 256 entries store multicast addresses, so we will end up attempting to insert duplicate filters, which is mostly harmless. If we add more than 288 unicast addresses we will then read past the multicast address table, which is likely to be more exciting.

We can't rely on kzalloc() always succeeding, so check its return value.

Commit 10e23eb2 ("mlxsw: spectrum: Remove support for bypass bridge port attributes/vlan set") removed statements that used 'bridge_vlan', but didn't remove the variable itself resulting in the following warning with W=1: warning: variable ‘bridge_vlan’ set but not used [-Wunused-but-set-variable] Remove the variable and suppress the warning.

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.
