If you pass an invalid string here then you probably deserve the memory
corruption, but it annoys static analysis tools so lets fix it.

Pull networking fixes from David Miller:
1) If an IPVS tunnel is created with a mixed-family destination
address, it cannot be removed. Fix from Alexey Andriyanov.
2) Fix module refcount underflow in netfilter's nft_compat, from Pablo
Neira Ayuso.
3) Generic statistics infrastructure can reference variables sitting on
a released function stack, therefore use dynamic allocation always.
Fix from Ignacy Gawędzki.
4) skb_copy_bits() return value test is inverted in ip_check_defrag().
5) Fix network namespace exit in openvswitch, we have to release all of
the per-net vports. From Pravin B Shelar.
6) Fix signedness bug in CAIF's cfpkt_iterate(), from Dan Carpenter.
7) Fix rhashtable grow/shrink behavior, only expand during inserts and
shrink during deletes. From Daniel Borkmann.
8) Netdevice names with semicolons should never be allowed, because
they serve as a separator. From Matthew Thode.
9) Use {,__}set_current_state() where appropriate, from Fabian
Frederick.
10) Revert byte queue limits support in r8169 driver, it's causing
regressions we can't figure out.
11) tcp_should_expand_sndbuf() erroneously uses tp->packets_out to
measure packets in flight, properly use tcp_packets_in_flight()
instead. From Neal Cardwell.
12) Fix accidental removal of support for bluetooth in CSR based Intel
wireless cards. From Marcel Holtmann.
13) We accidently added a behavioral change between native and compat
tasks, wrt testing the MSG_CMSG_COMPAT bit. Just ignore it if the
user happened to set it in a native binary as that was always the
behavior we had. From Catalin Marinas.
14) Check genlmsg_unicast() return valud in hwsim netlink tx frame
handling, from Bob Copeland.
15) Fix stale ->radar_required setting in mac80211 that can prevent
starting new scans, from Eliad Peller.
16) Fix memory leak in nl80211 monitor, from Johannes Berg.
17) Fix race in TX index handling in xen-netback, from David Vrabel.
18) Don't enable interrupts in amx-xgbe driver until all software et al.
state is ready for the interrupt handler to run. From Thomas
Lendacky.
19) Add missing netlink_ns_capable() checks to rtnl_newlink(), from Eric
W Biederman.
20) The amount of header space needed in macvtap was not calculated
properly, fix it otherwise we splat past the beginning of the
packet. From Eric Dumazet.
21) Fix bcmgenet TCP TX perf regression, from Jaedon Shin.
22) Don't raw initialize or mod timers, use setup_timer() and
mod_timer() instead. From Vaishali Thakkar.
23) Fix software maintained statistics in bcmgenet and systemport
drivers, from Florian Fainelli.
24) DMA descriptor updates in sh_eth need proper memory barriers, from
Ben Hutchings.
25) Don't do UDP Fragmentation Offload on RAW sockets, from Michal
Kubecek.
26) Openvswitch's non-masked set actions aren't constructed properly
into netlink messages, fix from Joe Stringer.

this hasn't happened. So I'm sending a few kconfig patches that I
collected:

drivers/net/vxlan.c
drivers/vhost/net.c
include/linux/if_vlan.h
net/core/dev.c
The net/core/dev.c conflict was the overlap of one commit marking an
existing function static whilst another was adding a new function.
In the include/linux/if_vlan.h case, the type used for a local
variable was changed in 'net', whereas the function got rewritten
to fix a stacked vlan bug in 'net-next'.
In drivers/vhost/net.c, Al Viro's iov_iter conversions in 'net-next'
overlapped with an endainness fix for VHOST 1.0 in 'net'.
In drivers/net/vxlan.c, vxlan_find_vni() added a 'flags' parameter
in 'net-next' whereas in 'net' there was a bug fix to pass in the
correct network namespace pointer in calls to this function.

The bug here is that we use "Reject" as the index into the cau_t[] array
in the else path. Since the cau_t[] has 9 elements if Reject == 9 then
we are reading beyond the end of the array.
My understanding of the code is that it's saying that if Reject is 1 or
too high then that's invalid and we should hang up.

Not all architectures are able to call __builtin_return_address().
On ARM, the mISDN code produces this warning:
hardware/mISDN/w6692.c: In function 'w6692_dctrl':
hardware/mISDN/w6692.c:1181:75: warning: unsupported argument to '__builtin_return_address'
pr_debug("%s: %s dev(%d) open from %p\n", card->name, __func__,
^
hardware/mISDN/mISDNipac.c: In function 'open_dchannel':
hardware/mISDN/mISDNipac.c:759:75: warning: unsupported argument to '__builtin_return_address'
pr_debug("%s: %s dev(%d) open from %p\n", isac->name, __func__,
^
In a lot of cases, this is relatively easy to work around by
passing the value of __builtin_return_address(0) from the
callers into the functions that want it. One exception is
the indirect 'open' function call in struct isac_hw. While it
would be possible to fix this as well, this patch only addresses
the other callers properly and lets this one return the direct
parent function, which should be good enough.

In C one can either use '\0' or '\x00' (or '\000') to add a NUL byte to
a string. '\0x00' isn't part of these and will in fact result in a
single NUL followed by "x00". This fixes that.

Kernel CAPI has been the recommended ISDN subsystem for the Gigaset

Replace a misspelled function name by %s and then __func__.
In the first case, the print is just dropped, because kmalloc itself does
