inet: defines IPPROTO_* needed for module alias generation
Commit cfd280c91253 ("net: sync some IP headers with glibc") changed a set of
define's to an enum (with no explanation why) which introduced a bug
in module mip6 where aliases are generated using the IPPROTO_* defines;
mip6 doesn't load if require_module called with the aliases from
xfrm_get_type().
Reverting this change back to define's to fix the aliases.
modinfo mip6 (before this change)
alias: xfrm-type-10-IPPROTO_DSTOPTS
alias: xfrm-type-10-IPPROTO_ROUTING
modinfo mip6 (after this change)
alias: xfrm-type-10-43
alias: xfrm-type-10-60

net: sctp: fix initialization of local source address on accepted ipv6 sockets
commit efe4208f47f907b86f528788da711e8ab9dea44d:
'ipv6: make lookups simpler and faster' broke initialization of local source
address on accepted ipv6 sockets. Before the mentioned commit receive address
was copied along with the contents of ipv6_pinfo in sctp_v6_create_accept_sk.
Now when it is moved, it has to be copied separately.
This also fixes lksctp's ipv6 regression in a sense that test_getname_v6, TC5 -
'getsockname on a connected server socket' now passes.

tg3: Fix deadlock in tg3_change_mtu()
Quoting David Vrabel -
"5780 cards cannot have jumbo frames and TSO enabled together. When
jumbo frames are enabled by setting the MTU, the TSO feature must be
cleared. This is done indirectly by calling netdev_update_features()
which will call tg3_fix_features() to actually clear the flags.
netdev_update_features() will also trigger a new netlink message for the

rtl8180: Add error check for pci_map_single return value in RX path
In original code the old RX DMA buffer is unmapped and processed and at the end
of the isr a new buffer is mapped with pci_map_single and attached to the RX
descriptor.
If pci_map_single fails then the RX descriptor remains with no valid DMA buffer
attached.
In this condition the DMA will target where it shouldn't with obvious evil
consequences.
Simply avoiding re-arming the descriptor will prevent buggy DMA but it will
result soon in RX stuck.
This patch move the DMA mapping of the new buffer at the beginning of the ISR
(and it adds error check for pci_map_single success/fail).
If the DMA mapping fails then we do not unmap the old buffer and we re-arm the
descriptor without processing it, with the old DMA buffer still attached.
In this way we lose the currently RX-ed packet, but whenever next calls to
pci_map_single will succeed again,then the RX process will go on without stuck.

mac80211: fix fragmentation code, particularly for encryption
The "new" fragmentation code (since my rewrite almost 5 years ago)
erroneously sets skb->len rather than using skb_trim() to adjust
the length of the first fragment after copying out all the others.
This leaves the skb tail pointer pointing to after where the data
originally ended, and thus causes the encryption MIC to be written
at that point, rather than where it belongs: immediately after the
data.
The impact of this is that if software encryption is done, then
a) encryption doesn't work for the first fragment, the connection
becomes unusable as the first fragment will never be properly
verified at the receiver, the MIC is practically guaranteed to
be wrong
b) we leak up to 8 bytes of plaintext (!) of the packet out into
the air
This is only mitigated by the fact that many devices are capable
of doing encryption in hardware, in which case this can't happen
as the tail pointer is irrelevant in that case. Additionally,
fragmentation is not used very frequently and would normally have
to be configured manually.

cfg80211: fix scan done race
When an interface/wdev is removed, any ongoing scan should be
cancelled by the driver. This will make it call cfg80211, which
only queues a work struct. If interface/wdev removal is quick
enough, this can leave the scan request pending and processed
only after the interface is gone, causing a use-after-free.
Fix this by making sure the scan request is not pending after
the interface is destroyed. We can't flush or cancel the work
item due to locking concerns, but when it'll run it shouldn't
find anything to do. This leaves a potential issue, if a new
scan gets requested before the work runs, it prematurely stops
the running scan, potentially causing another crash. I'll fix
that in the next patch.
This was particularly observed with P2P_DEVICE wdevs, likely
because freeing them is quicker than freeing netdevs.

- [THREAD] xenvif_rx_action sets rx_queue_stopped to true
- [INTERRUPT] interrupt happens, and sets rx_event to true
- [THREAD] then xenvif_kthread sets rx_event to false
- [THREAD] rx_work_todo doesn't return true anymore
Also, if interrupt sent but there is still no room in the ring, it take quite a
long time until xenvif_rx_action realize it. This patch ditch that two variable,
and rework rx_work_todo. If the thread finds it can't fit more skb's into the
ring, it saves the last slot estimation into rx_last_skb_slots, otherwise it's
kept as 0. Then rx_work_todo will check if:
- there is something to send to the ring (like before)
- there is space for the topmost packet in the queue

====================
bonding: Fix some issues for fail_over_mac
The parameter fail_over_mac only affect active-backup mode, if it was
set to active or follow and works with other modes, just like RR or XOR
mode, the bonding could not set all slaves to the master's address, it
will cause the slave could not work well with master.
v1->v2: According Jay's suggestion, that we should permit setting an option
at any time, but only have it take effect in active-backup mode, so
I add mode checking together with fail_over_mac during enslavement and
rebuild the patches.
v2->v3: The correct way to fix the problem is that we should not add restrictions when
setting options, just need to modify the bond enslave and removal processing
to check the mode in addition to fail_over_mac when setting a slave's MAC during
enslavement. The change active slave processing already only calls the fail_over_mac
function when in active-backup mode.
Remove the cleanup patch because the net-next is frozen now.

bonding: fail_over_mac should only affect AB mode in bond_set_mac_address()
The fail_over_mac could be set to active or follow in any time for all modes,
so if the fail_over_mac is not none and the current mode is not active-backup,
the bond_set_mac_address() could not change the master and slave's MAC address.
In bond_set_mac_address(), the fail_over_mac should only affect AB mode, so modify

sta_rc_update() callback must be atomic, hence we can not take mutexes
or do other operations, which can sleep in ath9k_htc_sta_rc_update().
I think we can just return from ath9k_htc_sta_rc_update(), if it is

with scheduling while atomic bug for most cases (except mesh and IBSS
modes).
For mesh and IBSS I do not see other solution like creating additional

this can be done in additional patch.

iwlwifi: mvm: don't allow A band if SKU forbids it
The driver wasn't reading the NVM properly. While this
didn't lead to any issue until now, it seems that there
is an old version of the NVM in the wild.
In this version, the A band channels appear to be valid
but the SKU capabilities (another field of the NVM) says
that A band isn't supported at all.
With this specific version of the NVM, the driver would
think that A band is supported while the HW / firmware
don't. This leads to asserts.

The reason is that the nfs #ifdef's for ACL support were misplaced, and
the nfs3 inode operations had the xattr operation pointers set up, even

was being called without the infrastructure having been set up.
