rtlwifi: rtl8821ae: Fix lockups on boot
In commit
54328e64047a5 ("rtlwifi: rtl8821ae: Fix system lockups on boot"),
an attempt was made to fix a regression introduced in commit
1277fa2ab2f9
("rtlwifi: Remove the clear interrupt routine from all drivers").
Unfortunately, there were logic errors in that patch that prevented
affected boxes from booting even after that patch was applied.
The actual cause of the original problem is unknown as none of the
developers have systems that are affected.

dl2k: Add support for IP1000A-based cards
Add support for IP1000A chips to dl2k driver.
IP1000A chip looks like a TC9020 with integrated PHY.
This allows IP1000A chips to work reliably because the ipg driver is
buggy - it loses packets under load and then completely stops
transmitting data.
Tested with Asus NX1101 v2.0 at 10, 100 and 1000Mbps:
vendor=0x13f0 device=0x1023 (rev 0x41)
subsystem vendor=0x1043 device=0x8180
MAC address registers access needed to be changed from 8-bit to 16-bit
because 8-bit does not work on IP1000A. 8-bit access is not even
allowed in the TC9020 datasheet (although it worked). 16-bit access
works on both.
Tested that it does not break D-Link DGE-550T (DL-2000 chip, probably
a rebranded TC9020):
vendor=0x1186 device=0x4000 (rev 0x0c)

reserve check should have reserve as 0, but currently, this is
unconditionally set (in it's original form as dev->hard_header_len).
I think this is not correct since tpacket_fill_skb() would then
take dev->mtu and dev->hard_header_len into account for SOCK_DGRAM,
the extra VLAN_HLEN could be possible in both cases. Presumably, the

packet: infer protocol from ethernet header if unset
In case no struct sockaddr_ll has been passed to packet
socket's sendmsg() when doing a TX_RING flush run, then
skb->protocol is set to po->num instead, which is the protocol
passed via socket(2)/bind(2).
Applications only xmitting can go the path of allocating the
socket as socket(PF_PACKET, <mode>, 0) and do a bind(2) on the
TX_RING with sll_protocol of 0. That way, register_prot_hook()
is neither called on creation nor on bind time, which saves
cycles when there's no interest in capturing anyway.
That leaves us however with po->num 0 instead and therefore
the TX_RING flush run sets skb->protocol to 0 as well. Eric
reported that this leads to problems when using tools like
trafgen over bonding device. I.e. the bonding's hash function
could invoke the kernel's flow dissector, which depends on
skb->protocol being properly set. In the current situation, all
the traffic is then directed to a single slave.
Fix it up by inferring skb->protocol from the Ethernet header
when not set and we have ARPHRD_ETHER device type. This is only
done in case of SOCK_RAW and where we have a dev->hard_header_len
length. In case of ARPHRD_ETHER devices, this is guaranteed to
cover ETH_HLEN, and therefore being accessed on the skb after
the skb_store_bits().

Packet sockets can be used by various net devices and are not

currently checking for the extra 4 bytes that can be transmitted

ARPHRD_ETHER devices. Therefore, before looking into Ethernet
header, check the device type first.
This also fixes the issue where non-ARPHRD_ETHER devices could

the check would test unfilled linear part of the skb (instead

so its rt6i_table == NULL. When __ip6_rt_update_pmtu() creates
a RTF_CACHE clone, the newly created clone also has rt6i_table == NULL
and it causes the ip6_ins_rt() oops.
During pmtu update, we only want to create a RTF_CACHE clone
from a rt which is currently managed (or owned) by the
fib6 tree. It means either rt->rt6i_node != NULL or
rt is a RTF_PCPU clone.
It is worth to note that rt6i_table may not be NULL even it is
not (yet) managed by the fib6 tree (e.g. addrconf_dst_alloc()).

iwlwifi: mvm: don't overwrite the key indices in D3 entry
When entering D3, we need to use hardcoded key indices because the
firmware requires that. To do so, we are overwriting the HW key index
in the keyconf structure, which makes it impossible to reuse the
indices that were used before entering D3. Additionally, we overwrite
all the non-PTK keys with index 1, because the firmware only allows
one non-PTK key to be set. This is bad, because when we resume, we
may try to set more than one key with index 1, which will obviously
fail.
To fix this, allow the callers to set a pre-defined index to use in
iwl_mvm_set_sta_key() instead of relying on the hw_key_idx value from
the keyconf struct (which requires overwriting it). In normal cases,
the caller can pass STA_KEY_IDX_INVALID, which will cause a new key
offset to be chosen. During HW_RESTART, we pass the offset that is in
use. And during D3 entry, we pass the hardcoded indices we need to
use.
Additionally, don't clear the fw_key_table in D3 entry, so that the
flags are still set with the pre-D3 values when exiting D3.

af-unix: fix use-after-free with concurrent readers while splicing
During splicing an af-unix socket to a pipe we have to drop all
af-unix socket locks. While doing so we allow another reader to enter
unix_stream_read_generic which can read, copy and finally free another
skb. If exactly this skb is just in process of being spliced we get a
use-after-free report by kasan.
First, we must make sure to not have a free while the skb is used during
the splice operation. We simply increment its use counter before unlocking
the reader lock.
Stream sockets have the nice characteristic that we don't care about
zero length writes and they never reach the peer socket's queue. That
said, we can take the UNIXCB.consumed field as the indicator if the
skb was already freed from the socket's receive queue. If the skb was
fully consumed after we locked the reader side again we know it has been
dropped by a second reader. We indicate a short read to user space and
abort the current splice operation.
This bug has been found with syzkaller
(http://github.com/google/syzkaller) by Dmitry Vyukov.

stmmac: avoid ipq806x constant overflow warning
Building dwmac-ipq806x on a 64-bit architecture produces a harmless
warning from gcc:
stmmac/dwmac-ipq806x.c: In function 'ipq806x_gmac_probe':
include/linux/bitops.h:6:19: warning: overflow in implicit constant conversion [-Woverflow]
val = QSGMII_PHY_CDR_EN |
stmmac/dwmac-ipq806x.c:333:8: note: in expansion of macro 'QSGMII_PHY_CDR_EN'
#define QSGMII_PHY_CDR_EN BIT(0)
#define BIT(nr) (1UL << (nr))
This is a result of the type conversion rules in C, when we take the
logical OR of multiple different types. In particular, we have
and unsigned long
QSGMII_PHY_CDR_EN == BIT(0) == (1ul << 0) == 0x0000000000000001ul
and a signed int
0xC << QSGMII_PHY_TX_DRV_AMP_OFFSET == 0xc0000000
which together gives a signed long value
0xffffffffc0000001l
and when this is passed into a function that takes an unsigned int type,
gcc warns about the signed overflow and the loss of the upper 32-bits that
are all ones.
This patch adds 'ul' type modifiers to the literal numbers passed in
here, so now the expression remains an 'unsigned long' with the upper
bits all zero, and that avoids the signed overflow and the warning.

Netfilter fixes for net
The following patchset contains Netfilter fixes for your net tree. This
large batch that includes fixes for ipset, netfilter ingress, nf_tables
dynamic set instantiation and a longstanding Kconfig dependency problem.
More specifically, they are:
1) Add missing check for empty hook list at the ingress hook, from
Florian Westphal.
2) Input and output interface are swapped at the ingress hook,
reported by Patrick McHardy.
3) Resolve ipset extension alignment issues on ARM, patch from Jozsef
Kadlecsik.
4) Fix bit check on bitmap in ipset hash type, also from Jozsef.
5) Release buckets when all entries have expired in ipset hash type,
again from Jozsef.
6) Oneliner to initialize conntrack tuple object in the PPTP helper,
otherwise the conntrack lookup may fail due to random bits in the
structure holes, patch from Anthony Lineham.
7) Silence a bogus gcc warning in nfnetlink_log, from Arnd Bergmann.
8) Fix Kconfig dependency problems with TPROXY, socket and dup, also
from Arnd.
9) Add __netdev_alloc_pcpu_stats() to allow creating percpu counters
from atomic context, this is required by the follow up fix for
nf_tables.
10) Fix crash from the dynamic set expression, we have to add new clone
operation that should be defined when a simple memcpy is not enough.
This resolves a crash when using per-cpu counters with new Patrick
McHardy's flow table nft support.
