Enablement of AMD's Secure Memory Encryption feature is determined very
early after start_kernel() is entered. Part of this procedure involves
scanning the command line for the parameter 'mem_encrypt'.
To determine intended state, the function sme_enable() uses library
functions cmdline_find_option() and strncmp(). Their use occurs early
enough such that it cannot be assumed that any instrumentation subsystem
is initialized.
For example, making calls to a KASAN-instrumented function before KASAN
is set up will result in the use of uninitialized memory and a boot
failure.
When AMD's SME support is enabled, conditionally disable instrumentation
of these dependent functions in lib/string.c and arch/x86/lib/cmdline.c.
[ bp: Get rid of intermediary nostackp var and cleanup whitespace. ]

git://git.kernel.org/pub/scm/linux/kernel/git/kvalo/wireless-drivers
Kalle Valo says:
====================
wireless-drivers fixes for 5.1
Third set of fixes for 5.1.
iwlwifi
* fix an oops when creating debugfs entries
* fix bug when trying to capture debugging info while in rfkill
* prevent potential uninitialized memory dumps into debugging logs
* fix some initialization parameters for AX210 devices
* fix an oops with non-MSIX devices
* fix an oops when we receive a packet with bogus lengths
* fix a bug that prevented 5350 devices from working
* fix a small merge damage from the previous series
mwifiex
* fig regression with resume on SDIO
ath10k
* fix locking problem with crashdump
* fix warnings during suspend and resume
Also note that this pull conflicts with net-next. And I want to emphasie
that it's really net-next, so when you pull this to net tree it should
go without conflicts. Stephen reported the conflict here:
https://lkml.kernel.org/r/20190429115338.5decb50b@canb.auug.org.au
In iwlwifi oddly commit 154d4899e411 adds the IS_ERR_OR_NULL() in
wireless-drivers but commit c9af7528c331 removes the whole check in
wireless-drivers-next. The fix is easy, just drop the whole check for
mvmvif->dbgfs_dir in iwlwifi/mvm/debugfs-vif.c, it's unneeded anyway.

There is no operation to order with afterwards, and removing the flag is

The application reading the CQ ring needs a barrier to pair with the
smp_store_release in io_commit_cqring, not the barrier after it.
Also a write barrier *after* writing something (but not *before*
writing anything interesting) doesn't order anything, so an smp_wmb()
after writing SQ tail is not needed.
Additionally consider reading SQ head and writing CQ tail in the notes.
Also add some clarifications how the various other fields in the ring
buffers are used.

In rxrpc_destroy_all_calls(), there are two phases: (1) make sure the
->calls list is empty, emitting error messages if not, and (2) wait for the
RCU cleanup to happen on outstanding calls (ie. ->nr_calls becomes 0).
To avoid taking the call_lock, the function prechecks ->calls and if empty,
it returns to avoid taking the lock - this is wrong, however: it still
needs to go and do the second phase and wait for ->nr_calls to become 0.
Without this, the rxrpc_net struct may get deallocated before we get to the
RCU cleanup for the last calls. This can lead to:
Slab corruption (Not tainted): kmalloc-16k start=ffff88802b178000, len=16384
050: 6b 6b 6b 6b 6b 6b 6b 6b 61 6b 6b 6b 6b 6b 6b 6b kkkkkkkkakkkkkkk
Note the "61" at offset 0x58. This corresponds to the ->nr_calls member of
struct rxrpc_net (which is >9k in size, and thus allocated out of the 16k
slab).
Fix this by flipping the condition on the if-statement, putting the locked
section inside the if-body and dropping the return from there. The
function will then always go on to wait for the RCU cleanup on outstanding
calls.

sending dest unreach
When there is no route to an IPv6 dest addr, skb_dst(skb) points
to loopback dev in the case of that the IP6CB(skb)->iif is
enslaved to a vrf. This causes Ip6InNoRoutes to be incremented on the
loopback dev. This also causes the lookup to fail on icmpv6_send() and
the dest unreachable to not sent and Ip6OutNoRoutes gets incremented on
the loopback dev.
To reproduce:
* Gateway configuration:
ip link add dev vrf_258 type vrf table 258
ip link set dev enp0s9 master vrf_258
ip addr add 66:1/64 dev enp0s9
ip -6 route add unreachable default metric 8192 table 258
sysctl -w net.ipv6.conf.all.forwarding=1
sysctl -w net.ipv6.conf.enp0s9.forwarding=1
* Sender configuration:
ip addr add 66::2/64 dev enp0s9
ip -6 route add default via 66::1
and ping 67::1 for example from the sender.
Fix this by counting on the original netdev and reset the skb dst to
force a fresh lookup.
v2: Fix typo of destination address in the repro steps.
v3: Simplify the loopback check (per David Ahern) and use reverse
Christmas tree format (per David Miller).

Richard and Bruno both reported that my commit added a bug,
and Bruno was able to determine the problem came when a segment
wih a FIN packet was coalesced to a prior one in tcp backlog queue.
It turns out the header prediction in tcp_rcv_established()
looks back to TCP headers in the packet, not in the metadata
(aka TCP_SKB_CB(skb)->tcp_flags)
The fast path in tcp_rcv_established() is not supposed to
handle a FIN flag (it does not call tcp_fin())
Therefore we need to make sure to propagate the FIN flag,
so that the coalesced packet does not go through the fast path,
the same than a GRO packet carrying a FIN flag.
While we are at it, make sure we do not coalesce packets with
RST or SYN, or if they do not have ACK set.
Many thanks to Richard and Bruno for pinpointing the bad commit,
and to Richard for providing a first version of the fix.

This doesn't really do anything, but at least we now parse teh
ZERO_PAGE() address argument so that we'll catch the most obvious errors
in usage next time they'll happen.

argument at all.

The parameter to ZERO_PAGE() was wrong, but since all architectures
except for MIPS and s390 ignore it, it wasn't noticed until 0-day

[...]
ath10k_pci_fw_crashed_dump() is called from NAPI contexts, and firmware
memory dumps are retrieved using the diag memory interface.
A simple reproduction case is to run this on QCA6174A /
WLAN.RM.4.4.1-00132-QCARMSWP-1, which happens to be a way to b0rk the
firmware:
dd if=/sys/kernel/debug/ieee80211/phy0/ath10k/mem_value bs=4K count=1
of=/dev/null
(NB: simulated firmware crashes, via debugfs, don't trigger firmware
dumps.)
The fix is to move the crash-dump into a workqueue context, and avoid
relying on 'data_lock' for most mutual exclusion. We only keep using it
here for protecting 'fw_crash_counter', while the rest of the coredump
buffers are protected by a new 'dump_mutex'.
I've tested the above with simulated firmware crashes (debugfs 'reset'
file), real firmware crashes (the 'dd' command above), and a variety of
reboot and suspend/resume configurations on QCA6174A.

All architectures which support stacktrace carry duplicated code and
do the stack storage and filtering at the architecture side.
Provide a consolidated interface with a callback function for consuming the
stack entries provided by the architecture specific stack walker. This
removes lots of duplicated code and allows to implement better filtering
than 'skip number of entries' in the future without touching any
architecture specific code.

The per cpu stack trace buffer usage pattern is odd at best. The buffer has
place for 512 stack trace entries on 64-bit and 1024 on 32-bit. When
interrupts or exceptions nest after the per cpu buffer was acquired the
stacktrace length is hardcoded to 8 entries. 512/1024 stack trace entries
in kernel stacks are unrealistic so the buffer is a complete waste.
Split the buffer into 4 nest levels, which are 128/256 entries per
level. This allows nesting contexts (interrupts, exceptions) to utilize the
cpu buffer for stack retrieval and avoids the fixed length allocation along
with the conditional execution pathes.

Replace the indirection through struct stack_trace by using the storage
array based interfaces.
The original code in all printing functions is really wrong. It allocates a
storage array on stack which is unused because depot_fetch_stack() does not
store anything in it. It overwrites the entries pointer in the stack_trace
struct so it points to the depot storage.
