gso: handle new frag_list of frags GRO packets
Recently GRO started generating packets with frag_lists of frags.
This was not handled by GSO, thus leading to a crash.
Thankfully these packets are of a regular form and are easy to
handle. This patch handles them in two ways. For completely
non-linear frag_list entries, we simply continue to iterate over
the frag_list frags once we exhaust the normal frags. For frag_list
entries with linear parts, we call pskb_trim on the first part
of the frag_list skb, and then process the rest of the frags in
the usual way.
This patch also kills a chunk of dead frag_list code that has
obviously never ever been run since it ends up generating a bogus
GSO-segmented packet with a frag_list entry.
Future work is planned to split super big packets into TSO
ones.

packet: fix use after free race in send path when dev is released
Salam reported a use after free bug in PF_PACKET that occurs when
we're sending out frames on a socket bound device and suddenly the
net device is being unregistered. It appears that commit
827d9780
introduced a possible race condition between {t,}packet_snd() and
packet_notifier(). In the case of a bound socket, packet_notifier()
can drop the last reference to the net_device and {t,}packet_snd()
might end up suddenly sending a packet over a freed net_device.
To avoid reverting
827d9780 and thus introducing a performance
regression compared to the current state of things, we decided to
hold a cached RCU protected pointer to the net device and maintain
it on write side via bind spin_lock protected register_prot_hook()
and __unregister_prot_hook() calls.
In {t,}packet_snd() path, we access this pointer under rcu_read_lock
through packet_cached_dev_get() that holds reference to the device
to prevent it from being freed through packet_notifier() while
we're in send path. This is okay to do as dev_put()/dev_hold() are
per-cpu counters, so this should not be a performance issue. Also,
the code simplifies a bit as we don't need need_rls_dev anymore.

net: rework recvmsg handler msg_name and msg_namelen logic
This patch now always passes msg->msg_namelen as 0. recvmsg handlers must
set msg_namelen to the proper size <= sizeof(struct sockaddr_storage)
to return msg_name to the user.
This prevents numerous uninitialized memory leaks we had in the
recvmsg handlers and makes it harder for new code to accidentally leak
uninitialized memory.
Optimize for the case recvfrom is called with NULL as address. We don't
need to copy the address at all, so set it to NULL before invoking the
recvmsg handler. We can do so, because all the recvmsg handlers must
cope with the case a plain read() is called on them. read() also sets
msg_name to NULL.
Also document these changes in include/linux/net.h as suggested by David
Miller.
Changes since RFC:
Set msg->msg_name = NULL if user specified a NULL in msg_name but had a
non-null msg_namelen in verify_iovec/verify_compat_iovec. This doesn't
affect sendto as it would bail out earlier while trying to copy-in the
address. It also more naturally reflects the logic by the callers of
verify_iovec.
With this change in place I could remove "
if (!uaddr || msg_sys->msg_namelen == 0)
msg->msg_name = NULL
".
This change does not alter the user visible error logic as we ignore
msg_namelen as long as msg_name is NULL.
Also remove two unnecessary curly brackets in ___sys_recvmsg and change
comments to netdev style.

net: core: Always propagate flag changes to interfaces
The following commit:
b6c40d68ff6498b7f63ddf97cf0aa818d748dee7
net: only invoke dev->change_rx_flags when device is UP
tried to fix a problem with VLAN devices and promiscuouse flag setting.
The issue was that VLAN device was setting a flag on an interface that
was down, thus resulting in bad promiscuity count.
This commit blocked flag propagation to any device that is currently
down.
A later commit:
deede2fabe24e00bd7e246eb81cd5767dc6fcfc7
vlan: Don't propagate flag changes on down interfaces
fixed VLAN code to only propagate flags when the VLAN interface is up,
thus fixing the same issue as above, only localized to VLAN.
The problem we have now is that if we have create a complex stack
involving multiple software devices like bridges, bonds, and vlans,
then it is possible that the flags would not propagate properly to
the physical devices. A simple examle of the scenario is the
following:
eth0----> bond0 ----> bridge0 ---> vlan50
If bond0 or eth0 happen to be down at the time bond0 is added to
the bridge, then eth0 will never have promisc mode set which is
currently required for operation as part of the bridge. As a
result, packets with vlan50 will be dropped by the interface.
The only 2 devices that implement the special flag handling are
VLAN and DSA and they both have required code to prevent incorrect
flag propagation. As a result we can remove the generic solution
introduced in
b6c40d68ff6498b7f63ddf97cf0aa818d748dee7 and leave
it to the individual devices to decide whether they will block
flag propagation or not.

ipv4: fix race in concurrent ip_route_input_slow()
CPUs can ask for local route via ip_route_input_noref() concurrently.
if nh_rth_input is not cached yet, CPUs will proceed to allocate
equivalent DSTs on 'lo' and then will try to cache them in nh_rth_input
via rt_cache_route()
Most of the time they succeed, but on occasion the following two lines:
orig = *p;
prev = cmpxchg(p, orig, rt);
in rt_cache_route() do race and one of the cpus fails to complete cmpxchg.
But ip_route_input_slow() doesn't check the return code of rt_cache_route(),
so dst is leaking. dst_destroy() is never called and 'lo' device
refcnt doesn't go to zero, which can be seen in the logs as:
unregister_netdevice: waiting for lo to become free. Usage count = 1
Adding mdelay() between above two lines makes it easily reproducible.

For rx_bottom(), the rx_desc should not be used to calculate the

1) Johannes Berg noticed two major deficiencies in our genetlink
registration. Some genetlink protocols we passing in constant
counts for their ops array rather than something like
ARRAY_SIZE(ops) or similar. Also, some genetlink protocols were
using fixed IDs for their multicast groups.
We have to retain these fixed IDs to keep existing userland tools

other protocols can not possibly conflict.
In dealing with these two problems, we actually now use less state

====================
genetlink: clean up multicast group APIs
The generic netlink multicast group registration doesn't have to
be dynamic, and can thus be simplified just like I did with the
ops. This removes some complexity in registration code.
Additionally, two users of generic netlink already use multicast
groups in a wrong way, add workarounds for those two to keep the
userspace API working, but at the same time make them not clash
with other users of multicast groups as might happen now.
While making it all a bit easier, also prevent such abuse by adding
checks to the APIs so each family can only use the groups it owns.

genetlink: make multicast groups const, prevent abuse
Register generic netlink multicast groups as an array with
the family and give them contiguous group IDs. Then instead
of passing the global group ID to the various functions that
send messages, pass the ID relative to the family - for most
families that's just 0 because the only have one group.
This avoids the list_head and ID in each group, adding a new
field for the mcast group ID offset to the family.
At the same time, this allows us to prevent abusing groups
again like the quota and dropmon code did, since we can now
check that a family only uses a group it owns.

The openvswitch has some indirection, assing ops/n_ops directly in

tcp: don't update snd_nxt, when a socket is switched from repair mode
snd_nxt must be updated synchronously with sk_send_head. Otherwise
tp->packets_out may be updated incorrectly, what may bring a kernel panic.
Here is a kernel panic from my host.
[ 103.043194] BUG: unable to handle kernel NULL pointer dereference at
0000000000000048
[ 103.044025] IP: [<

[ 146.301158] Call Trace:
[ 146.301158] [<
ffffffff815ab7f0>] tcp_ack+0xcc0/0x12c0
Before this panic a tcp socket was restored. This socket had sent and
unsent data in the write queue. Sent data was restored in repair mode,
then the socket was switched from reapair mode and unsent data was
restored. After that the socket was switched back into repair mode.
In that moment we had a socket where write queue looks like this:
snd_una snd_nxt write_seq
|_________|________|
|
sk_send_head
After a second switching from repair mode the state of socket was
changed:
snd_una snd_nxt, write_seq
|_________ ________|
|
sk_send_head
This state is inconsistent, because snd_nxt and sk_send_head are not
synchronized.
Bellow you can find a call trace, how packets_out can be incremented
twice for one skb, if snd_nxt and sk_send_head are not synchronized.
In this case packets_out will be always positive, even when
sk_write_queue is empty.
tcp_write_wakeup
skb = tcp_send_head(sk);
tcp_fragment
if (!before(tp->snd_nxt, TCP_SKB_CB(buff)->end_seq))
tcp_adjust_pcount(sk, skb, diff);
tcp_event_new_data_sent
tp->packets_out += tcp_skb_pcount(skb);
I think update of snd_nxt isn't required, when a socket is switched from
repair mode. Because it's initialized in tcp_connect_init. Then when a
write queue is restored, snd_nxt is incremented in tcp_event_new_data_sent,
so it's always is in consistent state.
I have checked, that the bug is not reproduced with this patch and
all tests about restoring tcp connections work fine.
