[ Upstream commit b6b5e8a691185606dfffff3198c89e3b4fd9d4f6 ]
This controller does not support EEE, but it may connect to a PHY
which supports EEE and advertises EEE by default, while its link
partner also advertises EEE. If this happens, the PHY enters low
power mode when the traffic rate is low and causes packet loss.
This patch disables EEE advertisement by default for any PHY that
gianfar connects to, to prevent the above unwanted outcome.

[ Upstream commit 8dfd2f22d3bf3ab7714f7495ad5d897b8845e8c1 ]
Callers of sprint_oid() do not check its return value before printing
the result. In the case where the OID is zero-length, -EBADMSG was
being returned without anything being written to the buffer, resulting
in uninitialized stack memory being printed. Fix this by writing
"(bad)" to the buffer in the cases where -EBADMSG is returned.

[ Upstream commit c8bcbfbd239ed60a6562964b58034ac8a25f4c31 ]
The name char array passed to btrfs_search_path_in_tree is of size
BTRFS_INO_LOOKUP_PATH_MAX (4080). So the actual accessible char indexes
are in the range of [0, 4079]. Currently the code uses the define but this
represents an off-by-one.
Implications:
Size of btrfs_ioctl_ino_lookup_args is 4096, so the new byte will be
written to extra space, not some padding that could be provided by the
allocator.
btrfs-progs store the arguments on stack, but kernel does own copy of
the ioctl buffer and the off-by-one overwrite does not affect userspace,
but the ending 0 might be lost.
Kernel ioctl buffer is allocated dynamically so we're overwriting
somebody else's memory, and the ioctl is privileged if args.objectid is
not 256. Which is in most cases, but resolving a subvolume stored in
another directory will trigger that path.
Before this patch the buffer was one byte larger, but then the -1 was
not added.

[ Upstream commit 58117672943734715bbe7565ac9f062effa524f0 ]
According to LS1021A RM, the value of PAL can be set so that the start of the
IP header in the receive data buffer is aligned to a 32-bit boundary. Normally,
setting PAL = 2 provides minimal padding to ensure such alignment of the IP
header.
However every incoming packet's 8-byte time stamp will be inserted into the
packet data buffer as padding alignment bytes when hardware time stamping is
enabled.
So we set the padding 8+2 here to avoid the flooded alignment faults:

[ Upstream commit da340f921d3454f1521671c7a5a43ad3331fbe50 ]
Prevent that a prefix flag is set based on invalid configuration data.
The validity.verify_base flag should only be set for alias devices.
Usually the unit address type is either one of base, PAV alias or
HyperPAV alias. But in cases where the unit address type is not set or
any other value the validity.verify_base flag might be set as well.
This would lead to follow on errors.
Explicitly check for alias devices and set the validity flag only for
them.

[ Upstream commit 5aa04b3eb6fca63d2e9827be656dcadc26d54e11 ]
When user tries to group imc (In-Memory Collections) event with
normal event, (sometime) kernel crashes with following log:
Faulting instruction address: 0x00000000
[link register ] c00000000010ce88 power_check_constraints+0x128/0x980

c00000000000b004 system_call+0x38/0xe0
'event_base' field of 'struct hw_perf_event' is used as flags for
normal hw events and used as memory address for imc events. While
grouping these two types of events, collect_events() tries to
interpret imc 'event_base' as a flag, which causes a corruption
resulting in a crash.
Consider only those events which belongs to 'perf_hw_context' in
collect_events().

[ Upstream commit 969de0988b77e5a57aac2f7270191a3c50540c52 ]
Commit be7635e7287e ("arch, ftrace: for KASAN put hard/soft IRQ entries
into separate sections") added a new linker section, SOFTIRQENTRY_TEXT,
to the linker scripts for most architectures. It didn't add it to any of
the linker scripts for the m68k architecture. This was not really a problem
because it is only defined if either of CONFIG_FUNCTION_GRAPH_TRACER or
CONFIG_KASAN are enabled - which can never be true for m68k.
However commit 229a71860547 ("irq: Make the irqentry text section
unconditional") means that SOFTIRQENTRY_TEXT is now always defined. So on
m68k we now end up with a separate ELF section for .softirqentry.text
instead of it being part of the .text section. On some m68k targets in some
configurations this can also cause a fatal link error:
LD vmlinux
/usr/local/bin/../m68k-uclinux/bin/ld.real: section .softirqentry.text loaded at [0000000010de10c0,0000000010de12dd] overlaps section .rodata loaded at [0000000010de10c0,0000000010e0fd67]
To fix add in the missing SOFTIRQENTRY_TEXT section into the m68k linker
scripts. I noticed that m68k is also missing the IRQENTRY_TEXT section,
so this patch also adds an entry for that too.

[ Upstream commit e814bccbafece52a24e152d2395b5d49eef55841 ]
My bisect scripts starting running into build failures when trying to
compile 4.15-rc1 with the builds failing with things like:
drivers/net/wireless/broadcom/brcm80211/brcmfmac/sdio.c:2078: error: Cannot parse struct or union!
The line in question is actually just a #define, but after some digging
it turns out that my scripts pass W=1 and since commit 3a025e1d1c2ea
("Add optional check for bad kernel-doc comments") that results in
kernel-doc running on each source file. The file in question has a
badly formatted comment immediately before the #define:
/**
* struct brcmf_skbuff_cb reserves first two bytes in sk_buff::cb for
* bus layer usage.
*/
which causes the regex in dump_struct to fail (lack of braces following
struct declaration) and kernel-doc returns 1, which causes the build
to fail.
Fix the issue by always returning 0 from kernel-doc when invoked with
-none. It successfully generates no documentation, and prints out any
issues.

prsctp_prune
[ Upstream commit d30fc5126efb0c33b7adf5966d3051db2c3d7721 ]
Now outstanding_bytes is only increased when appending chunks into one
packet and sending it at 1st time, while decreased when it is about to
move into retransmit queue. It means outstanding_bytes value is already
decreased for all chunks in retransmit queue.
However sctp_prsctp_prune_sent is a common function to check the chunks
in both transmitted and retransmit queue, it decrease outstanding_bytes
when moving a chunk into abandoned queue from either of them.
It could cause outstanding_bytes underflow, as it also decreases it's
value for the chunks in retransmit queue.
This patch fixes it by only updating outstanding_bytes for transmitted
queue when pruning queues for prsctp prio policy, the same fix is also
needed in sctp_check_transmitted.

[ Upstream commit cf87634c8b24e24bf379b8c6807c8b0fb5f23567 ]
There's been a reproducable USB OHCI/EHCI cpuidle related hang on omap4
for a while that happens after about 20 - 40 minutes on an idle system
with some data feeding device being connected, like a USB GPS device or
a cellular modem.
This issue happens in cpuidle states C2 and C3 and does not happen if
cpuidle is limited to C1 state only. The symptoms are that the whole
system hangs and never wakes up from idle, and if a watchdog is
configured the system reboots after a while.
Turns out that OHCI/EHCI devices on omap4 are trying to use the GIC
interrupt controller directly as a parent instead of the WUGEN. We
need to pass the interrupts through WUGEN to GIC to provide the wakeup
events for the processor.
Let's fix the issue by removing the gic interrupt-parent and use the
default interrupt-parent wakeupgen instead. Note that omap5.dtsi had
this already fixes earlier by commit 7136d457f365 ("ARM: omap: convert
wakeupgen to stacked domains") but we somehow missed omap4 at that
point.

The LastPowerStateEntered bitfield is present only for PM_CEFUSE
domain. This is not present in any of the other power domains. Hence
remove the generic am33xx_pwrdm_read_prev_pwrst hook which wrongly
reads the reserved bit fields for all the other power domains.
Reading the reserved bits leads to wrongly interpreting the low
power transitions for various power domains that do not have the
LastPowerStateEntered field. The pm debug counters values are wrong
currently as we are incrementing them based on the reserved bits.

[ Upstream commit d09220a887f70368afa79e850c95e74890c0a32d ]
With the CMA changes from Joonsoo Kim <iamjoonsoo.kim@lge.com>, it
was noticed that n900 stopped booting. After investigating it turned
out that n900 save_secure_ram_context does some whacky virtual to
physical address translation for the SRAM data address.
As we now only have minimal parts of omap3 idle code copied to SRAM,
running save_secure_ram_context() in SRAM is not needed. It only gets
called on PM init. And it seems there's no need to ever call this from
SRAM idle code.
So let's just keep save_secure_ram_context() in DDR, and pass it the
physical address of the parameters. We can do everything else in
omap-secure.c like we already do for other secure code.
And since we don't have any documentation, I still have no clue what
the values for 0, 1 and 1 for the parameters might be. If somebody has
figured it out, please do send a patch to add some comments.

commit 9fa68f620041be04720d0cbfb1bd3ddfc6310b24 upstream.
Currently, almost none of the keyed hash algorithms check whether a key
has been set before proceeding. Some algorithms are okay with this and
will effectively just use a key of all 0's or some other bogus default.
However, others will severely break, as demonstrated using
"hmac(sha3-512-generic)", the unkeyed use of which causes a kernel crash
via a (potentially exploitable) stack buffer overflow.
A while ago, this problem was solved for AF_ALG by pairing each hash
transform with a 'has_key' bool. However, there are still other places
in the kernel where userspace can specify an arbitrary hash algorithm by
name, and the kernel uses it as unkeyed hash without checking whether it
is really unkeyed. Examples of this include:
- KEYCTL_DH_COMPUTE, via the KDF extension
- dm-verity
- dm-crypt, via the ESSIV support
- dm-integrity, via the "internal hash" mode with no key given
- drbd (Distributed Replicated Block Device)
This bug is especially bad for KEYCTL_DH_COMPUTE as that requires no
privileges to call.
Fix the bug for all users by adding a flag CRYPTO_TFM_NEED_KEY to the
->crt_flags of each hash transform that indicates whether the transform
still needs to be keyed or not. Then, make the hash init, import, and
digest functions return -ENOKEY if the key is still needed.
The new flag also replaces the 'has_key' bool which algif_hash was
previously using, thereby simplifying the algif_hash implementation.

commit a208fa8f33031b9e0aba44c7d1b7e68eb0cbd29e upstream.
We need to consistently enforce that keyed hashes cannot be used without
setting the key. To do this we need a reliable way to determine whether
a given hash algorithm is keyed or not. AF_ALG currently does this by
checking for the presence of a ->setkey() method. However, this is
actually slightly broken because the CRC-32 algorithms implement
->setkey() but can also be used without a key. (The CRC-32 "key" is not
actually a cryptographic key but rather represents the initial state.
If not overridden, then a default initial state is used.)
Prepare to fix this by introducing a flag CRYPTO_ALG_OPTIONAL_KEY which
indicates that the algorithm has a ->setkey() method, but it is not
required to be called. Then set it on all the CRC-32 algorithms.
The same also applies to the Adler-32 implementation in Lustre.
Also, the cryptd and mcryptd templates have to pass through the flag
from their underlying algorithm.

skb_warn_bad_offload warns when packets enter the GSO stack that
require skb_checksum_help or vice versa. Do not warn on arbitrary

demonstrate another one with eth_type games.
In particular, suppress the warning when segmentation returns an
error, which is for reasons other than checksum offload.

commit f10b4cff98c6977668434fbf5dd58695eeca2897 upstream.
The rds_tcp_kill_sock() function parses the rds_tcp_conn_list
to find the rds_connection entries marked for deletion as part
of the netns deletion under the protection of the rds_tcp_conn_lock.
Since the rds_tcp_conn_list tracks rds_tcp_connections (which
have a 1:1 mapping with rds_conn_path), multiple tc entries in
the rds_tcp_conn_list will map to a single rds_connection, and will
be deleted as part of the rds_conn_destroy() operation that is
done outside the rds_tcp_conn_lock.
The rds_tcp_conn_list traversal done under the protection of
rds_tcp_conn_lock should not leave any doomed tc entries in
the list after the rds_tcp_conn_lock is released, else another
concurrently executiong netns delete (for a differnt netns) thread
may trip on these entries.

#0: (rtnl_mutex){+.+.}, at: [<000000004342eaa9>] rtnl_lock+0x17/0x20
net/core/rtnetlink.c:74
The problem, as Florian noted, is that nf_setsockopt() is always
called with the socket held, even if the lock itself is required only
for very tight scopes and only for some operation.
This patch addresses the issues moving the lock_sock() call only
where really needed, namely in ipv*_getorigdst(), so that nf_setsockopt()
does not need anymore to acquire both locks.

commit 1a38956cce5eabd7b74f94bab70265e4df83165e upstream.
Commit 136e92bbec0a switched local_nodes from an array to a bitmask
but did not add proper bounds checks. As the result
clusterip_config_init_nodelist() can both over-read
ipt_clusterip_tgt_info.local_nodes and over-write
clusterip_config.local_nodes.
Add bounds checks for both.

commit da17c73b6eb74aad3c3c0654394635675b623b3e upstream.
It looks like syzbot found its way into netfilter territory.
Issue here is that @name comes from user space and might
not be null terminated.
Out-of-bound reads happen, KASAN is not happy.
v2 added similar fix for xt_request_find_target(),
as Florian advised.
