hv_netvsc: fixes for VF removal path
Kernel crash is reported after VF is removed and detached from netvsc
device. Turns out we have multiple different (but related) issues on the
VF removal path which I'm trying to address with PATCHes 2-5 of this
series. PATCH1 is required to support the change.
Changes since v1:
- Re-arrange patches in the series to not introduce new issues [David Miller]
- Add PATCH5 which fixes a new issue I discovered while testing.
- Add Haiyang' A-b tags to PATCH1-4
With regards to Stephen's suggestion: I believe that switching to using RCU
and eliminating vf_use_cnt/vf_inject is the right thing to do long-term, we
can either put this on top of this series or do it later in net-next.

Bonding driver sets IFF_BONDING on both master (the bonding device) and
slave (the real NIC) devices and in netvsc_netdev_event() we want to skip
master devices only. Currently, there is an uncertainty when a slave
interface is removed: if bonding module comes first in netdev_chain it
clears IFF_BONDING flag on the netdev and netvsc_netdev_event() correctly
handles NETDEV_UNREGISTER event, but in case netvsc comes first on the
chain it sees the device with IFF_BONDING still attached and skips it. As
we still hold vf_netdev pointer to the device we crash on the next inject.

Here is a deadlock scenario:
- netvsc_vf_up() schedules netvsc_notify_peers() work and quits.
- netvsc_vf_down() runs before netvsc_notify_peers() gets executed. As it
is being executed from netdev notifier chain we hold rtnl lock when we
get here.
- we enter while (atomic_read(&net_device_ctx->vf_use_cnt) != 0) loop and
wait till netvsc_notify_peers() drops vf_use_cnt.
- netvsc_notify_peers() starts on some other CPU but netdev_notify_peers()
will hang on rtnl_lock().
- deadlock!
Instead of introducing additional synchronization I suggest we drop
gwrk.dwrk completely and call NETDEV_NOTIFY_PEERS directly. As we're
acting under rtnl lock this is legitimate.

Ensure that the inner_protocol is set on transmit so that GSO segmentation,
which relies on that field, works correctly.
This is achieved by setting the inner_protocol in gre_build_header rather
than each caller of that function. It ensures that the inner_protocol is
set when gre_fb_xmit() is used to transmit GRE which was not previously the
case.
I have observed this is not the case when OvS transmits GRE using
lwtunnel metadata (which it always does).

====================
cxgb4: Add support for IFLA_VF_MAC
We're struggling to implement the PCI SR-IOV management features for
administering Virtual Functions which represent networking devices using
the current Linux APIs. The problem is that these APIs incorporate all
sorts of assumptions which don't match chelsio networking cards.
For instance, the current APIs assume a 1-to-1 mapping of Network Ports,
Physical Functions and the SR-IOV Virtual Functions of those Physical
Functions. This is not the case with our cards where any Virtual Function
can be hooked up to any Port -- or any number of Ports the current Linux
APIs also assume only 1 Network Interface/Port can be accessed per Virtuali
Function.
Another issue is that these APIs assume that the Administrative Driver is
attached to the Physical Function Associated with a Virtual Function. This
is not the case with our card where all administration is performed by a
Driver which is not attached to any of the Physical Functions which have
SR-IOV PCI Capabilities.
Another consequence of these assumptions is the inability to utilize all
of the cards SR-IOV resources. For instance, our cards have SR-IOV
Capabilities on Physical Functions 0..3 and the administrative Driver
attaches to Physical Function 4. Each of the Physical Functions 0..3 can
support up to 16 Virtual Functions. With the current Linux APIs, a 2-Port
card would only be able to use the Virtual Functions on Physical
Function 0..1 and not allow the Virtual Functions on Physical
Functions 2..3 to be used since there are no Ports 2..3 on a 2-Port card.
Patch 1/2 adds support to create management interface for each PF to control
thier corresponding VF's. Patch 2/2 adds support for ndo_set_vf_mac.
This patch series has been created against net-next tree.
We have included all the maintainers of respective drivers. Kindly review
the change and let us know in case of any review comments.

Fix:
Since the control node is always the netdevice for all VF ACL commands.
Created a dummy netdevice for each Physical Function from 0 to 3 through
which one could control their VFs. The device won't be associated with
any port, since it doesn't need to transmit/receive. Its purely used
for VF management purpose only. The device will be registered only when
VF for a particular PF is configured using PCI sysfs interface and
unregistered while pci_disable_sriov() for the PF is called.

The failure happens when allocating the spinlock array.
Even with GFP_KERNEL its unlikely for such a large allocation
to succeed.
Thomas Graf pointed me at inet_ehash_locks_alloc(), so in addition
to adding NOWARN for atomic allocations this also makes the bucket-array
sizing more conservative.
In commit 095dc8e0c3 ("tcp: fix/cleanup inet_ehash_locks_alloc()"),
Eric Dumazet says: "Budget 2 cache lines per cpu worth of 'spinlocks'".
IOW, consider size needed by a single spinlock when determining
number of locks per cpu. So with 64 byte per cacheline and 4 byte per
spinlock this gives 32 locks per cpu.
Resulting size of the lock-array (sizeof(spinlock) == 4):
cpus: 1 2 4 8 16 32 64
old: 1k 1k 4k 8k 16k 16k 16k
new: 128 256 512 1k 2k 4k 8k
8k allocation should have decent chance of success even
with GFP_ATOMIC, and should not fail with GFP_KERNEL.
With 72-byte spinlock (LOCKDEP):
cpus : 1 2
old: 9k 18k
new: ~2k ~4k

Make /proc per net namespace objects belong to container
Currently [almost] all /proc objects belong to the global root, even if

access the data.
This series changes ownership of net namespace /proc objects
(/proc/net/self/* and /proc/sys/net/*) to be container's root and not
global root when there exists mapping for container's root in user

This helps when running Android CTS in a container, but I think it makes
sense regardless.

This also allows us to clean up net_ctl_permissions() because we do not

When CONFIG_NET_NS is disabled, registering pernet operations causes
init() to be called immediately with init_net as an argument. Unfortunately
this leads to some pernet ops, such as proc_net_ns_init() to be called too
early, when init_net namespace has not been fully initialized. This causes
issues when we want to change pernet ops to use more data from the net
namespace in question, for example reference user namespace that owns our
network namespace.
To fix this we could either play game of musical chairs and rearrange init
order, or we could do the same as when CONFIG_NET_NS is enabled, and
postpone calling pernet ops->init() until namespace is set up properly.
Note that we can not simply undo commit ed160e839d ("[NET]: Cleanup
pernet operation without CONFIG_NET_NS") and use the same implementations
for __register_pernet_operations() and __unregister_pernet_operations(),
because many pernet ops are marked as __net_initdata and will be discarded,
which wreaks havoc on our ops lists. Here we rely on the fact that we only
use lists until init_net is fully initialized, which happens much earlier
than discarding __net_initdata sections.
