Nikolay Aleksandrov 6f09a69130 net: bridge: vlan: fix vlan range dumps starting with pvid 
[ Upstream commit 43171c97e4 ]

There is a bug in all range dumps that rely on br_vlan_can_enter_range()
when the PVID is a range starting VLAN, all following VLANs that match
its flags can enter the range, but when the range is filled in only the
PVID VLAN is dumped and the rest of the range is discarded because
br_vlan_fill_vids() checks for the PVID flag. Since the PVID VLAN can
be only one, we need to break ranges around it, the best way to do that
consistently for all is to alter br_vlan_can_enter_range() to take into
account the PVID and return false to break the range when it's matched.

Before the fix:
$ ip l add br0 type bridge vlan_filtering 1
$ ip l add dumdum type dummy
$ ip l set dumdum master br0
$ ip l set br0 up
$ ip l set dumdum up
$ bridge vlan add dev dumdum vid 1 pvid untagged master
$ bridge vlan add dev dumdum vid 2 untagged master
$ bridge vlan show dev dumdum # use legacy dump to show all vlans
port              vlan-id
dumdum            1 PVID Egress Untagged
                  2 Egress Untagged

$ bridge -d vlan show dev dumdum # use the new dump (RTM_GETVLAN)
port              vlan-id
dumdum            1 PVID Egress Untagged
                    state forwarding mcast_router 1

VLAN 2 is missing, and if there are more matching VLANs afterwards
they'd be missing too.

After the fix:
[ same setup steps ]
$ bridge vlan show dev dumdum
port              vlan-id
dumdum            1 PVID Egress Untagged
                  2 Egress Untagged
$ bridge -d vlan show dev dumdum # use the new dump (RTM_GETVLAN)
port              vlan-id
dumdum            1 PVID Egress Untagged
                    state forwarding mcast_router 1
                  2 Egress Untagged
                    state forwarding mcast_router 1

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
