net-sysfs: convert dev->operstate reads to lockless ones

operstate_show() can omit dev_base_lock acquisition only
to read dev->operstate
net-sysfs: convert dev->operstate reads to lockless ones
[ Upstream commit 004d138364fd10dd5ff8ceb54cfdc2d792a7b338 ]
operstate_show() can omit dev_base_lock acquisition only
to read dev->operstate.
Annotate accesses to dev->operstate.
Writers still acquire dev_base_lock for mutual exclusion.

rtnetlink: Correct nested IFLA_VF_VLAN_LIST attribute validation

Each attribute inside a nested IFLA_VF_VLAN_LIST is assumed to be a
str
rtnetlink: Correct nested IFLA_VF_VLAN_LIST attribute validation
[ Upstream commit 1aec77b2bb2ed1db0f5efc61c4c1ca3813307489 ]
Each attribute inside a nested IFLA_VF_VLAN_LIST is assumed to be a
struct ifla_vf_vlan_info so the size of such attribute needs to be at least
of sizeof(struct ifla_vf_vlan_info) which is 14 bytes.
The current size validation in do_setvfinfo is against NLA_HDRLEN (4 bytes)
which is less than sizeof(struct ifla_vf_vlan_info) so this validation
is not enough and a too small attribute might be cast to a
struct ifla_vf_vlan_info, this might result in an out of bands
read access when accessing the saved (casted) entry in ivvl.

rtnetlink: Correct nested IFLA_VF_VLAN_LIST attribute validation

str
rtnetlink: Correct nested IFLA_VF_VLAN_LIST attribute validation
[ Upstream commit 1aec77b2bb2ed1db0f5efc61c4c1ca3813307489 ]
Each attribute inside a nested IFLA_VF_VLAN_LIST is assumed to be a
struct ifla_vf_vlan_info so the size of such attribute needs to be at least
of sizeof(struct ifla_vf_vlan_info) which is 14 bytes.
The current size validation in do_setvfinfo is against NLA_HDRLEN (4 bytes)
which is less than sizeof(struct ifla_vf_vlan_info) so this validation
is not enough and a too small attribute might be cast to a
struct ifla_vf_vlan_info, this might result in an out of bands
read access when accessing the saved (casted) entry in ivvl.

Annotate accesses to dev->operstate.
Writers still acquire dev_base_lock for mutual exclusion.
