The reproducer triggers:

1018 goto out;

in xfrm_policy_walk() via pfkey (it sets tiny rcv space, dump
callback returns -ENOBUFS).
In this case, *walk is located the pfkey socket struct, so this socket
becomes visible in the global policy list.
It looks like this is intentional -- phony walker has walk.dead set to 1
and all other places skip such "policies".
Ccing original authors of the two commits that seem to expose this
issue (first patch missed ->dead check, second patch adds pfkey
sockets to policies dumper list).

commit 58fc7f73a85d45a47057dad2af53502fdf6cf778 upstream.
As syzkaller spotted, currently caiaq driver submits a URB with the
fixed EP without checking whether it's actually available, which may
result in a kernel warning like:

From: Paul Moore <[email protected]>
commit ef28df55ac27e1e5cd122e19fa311d886d47a756 upstream.
The syzbot/syzkaller automated tests found a problem in
security_context_to_sid_core() during early boot (before we load the
SELinux policy) where we could potentially feed context strings without
NUL terminators into the strcmp() function.
We already guard against this during normal operation (after the SELinux
policy has been loaded) by making a copy of the context strings and
explicitly adding a NUL terminator to the end. The patch extends this
protection to the early boot case (no loaded policy) by moving the context
copy earlier in security_context_to_sid_core().

commit e5571240236c5652f3e079b1d5866716a7ad819c upstream.
This is needed to prevent sk_user_data being overwritten.
The check is done under the callback lock. This should prevent
a socket from being attached twice to a KCM mux. It also prevents
a socket from being attached for other use cases of sk_user_data
as long as the other cases set sk_user_data under the lock.
Followup work is needed to unify all the use cases of sk_user_data
to use the same locking.

commit b1bdcb59b64f806ef08d25a85c39ffb3ad841ce6 upstream.
xfrm_policy_cache_flush can sleep, so it cannot be called while holding
a spinlock. We could release the lock first, but I don't see why we need
to invoke this function here in first place, the packet path won't reuse
an xdst entry unless its still valid.
While at it, add an annotation to xfrm_policy_cache_flush, it would
have probably caught this bug sooner.

From: Sowmini Varadhan <[email protected]>
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.

[ Upstream commit 100d6de2ced538c539d923dc14a1b5cbae234503 ]
Currently there is only one sdbuf per Control QP (CQP) for
programming Segment Descriptor (SD). If multiple SD work
requests are posted simultaneously, the sdbuf is reused
by all WQEs and new WQEs can corrupt previous WQEs sdbuf
leading to incorrect SD programming.
Fix this by allocating one sdbuf per CQP SQ WQE. When an
SD command is posted, it will use the corresponding sdbuf
for the WQE.

There are many instructions, esp on PowerPC, whose mnemonics are longer
than 6 characters. Using precision limit causes truncation of such
mnemonics.
Fix this by removing precision limit. Note that, 'width' is still 6, so
alignment won't get affected for length <= 6.

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.

The MDIO busses need to be unregistered before they are freed,
otherwise BUG() is called. Add a call to the unregister code if the
registration fails, since we can have multiple busses, of which some
may correctly register before one fails. This requires moving the code
around a little.

Commit c6887cd11149 ("Btrfs: don't do nocow check unless we have to")
changed the behavior of __btrfs_buffered_write() so that it first tries
to get a data space reservation, and then skips the relatively expensive
nocow check if the reservation succeeded.
If we have quotas enabled, the data space reservation also includes a
quota reservation. But in the rewrite case, the space has already been
accounted for in qgroups. So btrfs_check_data_free_space() increases
the quota reservation, but it never gets decreased when the data
actually gets written and overwrites the pre-existing data. So we're
left with both the qgroup and qgroup reservation accounting for the same
space.
This commit adds the missing btrfs_qgroup_free_data() call in the case
of BTRFS_ORDERED_PREALLOC extents.

[ Upstream commit 6d60ce384d1d5ca32b595244db4077a419acc687 ]
If something calls ioremap() with an address not aligned to PAGE_SIZE, the
returned address might be not aligned as well. This led to a probe
registered on exactly the returned address, but the entire page was armed
for mmiotracing.
On calling iounmap() the address passed to unregister_kmmio_probe() was
PAGE_SIZE aligned by the caller leading to a complete freeze of the
machine.
We should always page align addresses while (un)registerung mappings,
because the mmiotracer works on top of pages, not mappings. We still keep
track of the probes based on their real addresses and lengths though,
because the mmiotrace still needs to know what are mapped memory regions.
Also move the call to mmiotrace_iounmap() prior page aligning the address,
so that all probes are unregistered properly, otherwise the kernel ends up
failing memory allocations randomly after disabling the mmiotracer.

While registering the cpuhotplug callbacks for nest-imc, if we fail in
the cpuhotplug online path for any random node in a multi node
system (because the opal call to stop nest-imc counters fails for that
node), ppc_nest_imc_cpu_offline() will get invoked for other nodes who
successfully returned from cpuhotplug online path.
This call trace is generated since in the ppc_nest_imc_cpu_offline()
path we are trying to migrate the event context, when nest-imc
counters are not even initialized.
Patch to add a check to ensure that nest-imc is registered before
migrating the event context.

The alternative intel_backlight_device_register() definition apparently
never got used, but I have now run into a case of i915 being compiled
without CONFIG_BACKLIGHT_CLASS_DEVICE, resulting in a number of
identical warnings:
drivers/gpu/drm/i915/intel_drv.h:1739:12: error: 'intel_backlight_device_register' defined but not used [-Werror=unused-function]
This marks the function as 'inline', which was surely the original
intention here.

I was seeing disk flushes still happening when I mounted a Btrfs
filesystem with nobarrier for testing. This is because we use FUA to
write out the first super block, and on devices without FUA support, the
block layer translates FUA to a flush. Even on devices supporting true
FUA, using FUA when we asked for no barriers is surprising.

From: Nikolay Borisov <[email protected]>
[ 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.

Indeed, pci_free_host_bridge() frees the PCI host bridge, including the

earlyprintk=efi,keep does not work any more with a warning
in mm/early_ioremap.c: WARN_ON(system_state != SYSTEM_BOOTING):
Boot just hangs because of the earlyprintk within the earlyprintk
implementation code itself.
This is caused by a new introduced middle state in:
69a78ff226fe ("init: Introduce SYSTEM_SCHEDULING state")
early_ioremap() is fine in both SYSTEM_BOOTING and SYSTEM_SCHEDULING
states, original condition should be updated accordingly.

DWC3_DEPCMD_ENDTRANSFER has been witnessed to require around 600 iterations

Mistakenly the driver didn't allow RSS hash fields combinations which
involve both IPv4 and IPv6 protocols. This bug caused to failures for
user's use cases for RSS.
Consequently, this patch fixes this bug and allows any combination that
the HW can support.
Additionally, the patch fixes the driver to return an error in case the
user provides an unsupported mask for RSS hash fields.

[ Upstream commit 732706afe1cc46ef48493b3d2b69c98f36314ae4 ]
On policies with a transport mode template, we pass the addresses
from the flowi to xfrm_state_find(), assuming that the IP addresses
(and address family) don't change during transformation.
Unfortunately our policy template validation is not strict enough.
It is possible to configure policies with transport mode template
where the address family of the template does not match the selectors
address family. This lead to stack-out-of-bound reads because
we compare arddesses of the wrong family. Fix this by refusing
such a configuration, address family can not change on transport
mode.
We use the assumption that, on transport mode, the first templates
address family must match the address family of the policy selector.
Subsequent transport mode templates must mach the address family of
the previous template.

in the open/close/release code paths") reintroduced the SS_DISCONNECTING
constant.
This patch replaces the old SS_DISCONNECTING with the new TCP_CLOSING
constant.

commit 48d83282db077f93b2cf40de120f4d6f29eb293b upstream.
A regression fix introduced a harmless type mismatch warning:
drivers/scsi/bfa/bfad_bsg.c: In function 'bfad_im_bsg_vendor_request':
drivers/scsi/bfa/bfad_bsg.c:3137:35: error: initialization of 'struct bfad_im_port_s *' from 'long unsigned int' makes pointer from integer without a cast [-Werror=int-conversion]

struct bfad_im_port_s *im_port = shost->hostdata[0];
This changes the code back to shost_priv() once more, but encapsulates
it in an inline function to document the rather unusual way of
using the private data only as a pointer to the previously allocated
structure.
I did not try to get rid of the extra indirection level entirely,
which would have been rather invasive and required reworking the entire
initialization sequence.

[ Upstream commit 6ab405114b0b229151ef06f4e31c7834dd09d0c0 ]
Check whether inputs from userspace are too long (explicit length field too
big or string not null-terminated) to avoid out-of-bounds reads.
As far as I can tell, this can at worst lead to very limited kernel heap
memory disclosure or oopses.
This bug can be triggered by an unprivileged user even if the xt_bpf module
is not loaded: iptables is available in network namespaces, and the xt_bpf
module can be autoloaded.
Triggering the bug with a classic BPF filter with fake length 0x1000 causes
the following KASAN report:

[ Upstream commit 3d5fdba1842bdd2eef29364c660558cb4cbb3fe0 ]
When removing the interrupt handling code, we should mask the
generation of interrupts. The code however unmasked all
interrupts. This can then cause a new interrupt. We then get into a
deadlock where the interrupt thread is waiting to run, and the code
continues, trying to remove the interrupt handler, which means waiting
for the thread to complete. On a UP machine this deadlocks.
Fix so we really mask interrupts in the hardware. The same error is
made in the error path when install the interrupt handling code.

Reserved and unused fields in the Tx descriptors should be 0. The PPv2
driver doesn't clear them at run-time (for performance reasons) but
these descriptors aren't zeroed when allocated, which can lead to
unpredictable behaviors. This patch fixes this by using
dma_zalloc_coherent instead of dma_alloc_coherent.

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:

Since it is perfectly legal to run the kernel at EL1, it is not
actually an error if HYP mode is not available when attempting to
initialize KVM, given that KVM support cannot be built as a module.
So demote the kvm_err() to kvm_info(), which prevents the error from
appearing on an otherwise 'quiet' console.

[ 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 a7f3f939dd7d8398acebecd1ceb2e9e7ffbe91d2 ]
The current 'bnxt_shutdown' implementation only invokes
'bnxt_ulp_shutdown' to shut down RoCE in the case when the system is in
the path of power off (SYSTEM_POWER_OFF). While this may work in most
cases, it does not work in the smart NIC case, when Linux 'reboot'
command is initiated from the Linux that runs on the ARM cores of the
NIC card. In this particular case, Linux 'reboot' results in a system
'L3' level reset where the entire ARM and associated subsystems are
being reset, but at the same time, Nitro core is being kept in sane state
(to allow external PCIe connected servers to continue to work). Without
properly shutting down RoCE and freeing all associated resources, it
results in the ARM core to hang immediately after the 'reboot'
By always invoking 'bnxt_ulp_shutdown' in 'bnxt_shutdown', it fixes the
above issue

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.

Test case 21 (Number of exit events of a simple workload) fails on
s390x. The reason is the invalid sample frequency supplied for this
test. On s390x the minimum sample frequency is much higher (see output
of /proc/service_levels).
Supply a save sample frequency value for s390x to fix this. The value
will be adjusted by the s390x CPUMF frequency convertion function to a
value well below the sysctl kernel.perf_event_max_sample_rate value.

[ 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.

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 a283cdc4d3670700182c820b59078387f9a01a30 ]
The ARP table entry indexes are aliased to 12bits
instead of the intended 16bits when uploaded to
the QP Context. This will present an issue when the
number of connections exceeds 4096 as ARP entries are
reused. Fix this by adjusting the mask to account for
the full 16bits.

vgic_set_owner acquires the irq lock without disabling interrupts,
resulting in a lockdep splat (an interrupt could fire and result
in the same lock being taken if the same virtual irq is to be
injected).
In practice, it is almost impossible to trigger this bug, but
better safe than sorry. Convert the lock acquisition to a
spin_lock_irqsave() and keep lockdep happy.

On the A80 the pins on port B can trigger interrupts, and those are
assigned to the second interrupt bank.
Having two pins assigned to the same interrupt bank/pin combination does
not look healthy (instead more like a copy&paste bug from pins PA14-PA16),
so fix the interrupt bank for pins PB14-PB16, which is actually 1.
I don't have any A80 board, so could not test this.

[ Upstream commit a158531f3c92467df0e93e000d58185acae78a6e ]
Commit 7ebc194d0fd4bb0f ("gpio: 74x164: Introduce 'enable-gpios'
property") added a new member gpiod_oe to the end of the struct
gen_74x164_chip, after the zero-length buffer array.
However, this buffer is a flexible array, allocated together with the
structure during .probe(). As the buffer is no longer the last member,
writing to it corrupts the newly added member after it.
During device removal, the corrupted member will be used as a pointer,
leading to a crash.
This went unnoticed, as the flexible array was declared as "buffer[0]"
instead of "buffer[]", and thus did not trigger a "flexible array member
not at end of struct" error from gcc.
Move the gpiod_oe field up to fix this, and drop the zero from the array
size to prevent future similar bugs.

------------------
From: Sowmini Varadhan <[email protected]>
commit 681648e67d43cf269c5590ecf021ed481f4551fc upstream.
Commit 8edc3affc077 ("rds: tcp: Take explicit refcounts on struct net")
introduces a regression in rds-tcp netns cleanup. The cleanup_net(),
(and thus rds_tcp_dev_event notification) is only called from put_net()
when all netns refcounts go to 0, but this cannot happen if the
rds_connection itself is holding a c_net ref that it expects to
release in rds_tcp_kill_sock.
Instead, the rds_tcp_kill_sock callback should make sure to
tear down state carefully, ensuring that the socket teardown
is only done after all data-structures and workqs that depend
on it are quiesced.
The original motivation for commit 8edc3affc077 ("rds: tcp: Take explicit
refcounts on struct net") was to resolve a race condition reported by
syzkaller where workqs for tx/rx/connect were triggered after the
namespace was deleted. Those worker threads should have been
cancelled/flushed before socket tear-down and indeed,
rds_conn_path_destroy() does try to sequence this by doing
/* cancel cp_send_w */
/* cancel cp_recv_w */
/* flush cp_down_w */
/* free data structures */
Here the "flush cp_down_w" will trigger rds_conn_shutdown and thus
invoke rds_tcp_conn_path_shutdown() to close the tcp socket, so that
we ought to have satisfied the requirement that "socket-close is
done after all other dependent state is quiesced". However,
rds_conn_shutdown has a bug in that it *always* triggers the reconnect
workq (and if connection is successful, we always restart tx/rx
workqs so with the right timing, we risk the race conditions reported
by syzkaller).
Netns deletion is like module teardown- no need to restart a
reconnect in this case. We can use the c_destroy_in_prog bit
to avoid restarting the reconnect.

[ Upstream commit 89d0aeab4252adc2a7ea693637dd21c588bfa2d1 ]
The stdio perf top crashes when we change the terminal
window size. The reason is that we assumed we get the
perf_top pointer as a signal handler argument which is
not the case.
Changing the SIGWINCH handler logic to change global
resize variable, which is checked in the main thread
loop.

From: Cong Wang <[email protected]>
commit 7dc68e98757a8eccf8ca7a53a29b896f1eef1f76 upstream.
rateest_hash is supposed to be protected by xt_rateest_mutex,
and, as suggested by Eric, lookup and insert should be atomic,
so we should acquire the xt_rateest_mutex once for both.
So introduce a non-locking helper for internal use and keep the
locking one for external.

commit 3f34cfae1238848fd53f25e5c8fd59da57901f4b upstream.
Syzbot reported several deadlocks in the netfilter area caused by
rtnl lock and socket lock being acquired with a different order on
different code paths, leading to backtraces like the following one:

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.

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(),

From: Douglas Gilbert <[email protected]>
commit 69e0927b3774563c19b5fb32e91d75edc147fb62 upstream.
During stress tests by syzkaller on the sg driver the block layer
infrequently returns EINVAL. Closer inspection shows the block
layer was trying to return ENOMEM (which is much more
understandable) but for some reason overroad that useful error.
Patch below does not show this (unchanged) line:
ret =__blk_rq_map_user_iov(rq, map_data, &i, gfp_mask, copy);
That 'ret' was being overridden when that function failed.

[ Upstream commit ccafc38f1c778847ab6d53dd7933260426731cf3 ]
This 'perf test' case fails on s390x. The 'touch' command on s390x uses
the 'openat' system call to open the file named on the command line:
[root@s35lp76 perf]# perf probe -l
probe:vfs_getname (on getname_flags:72@fs/namei.c with pathname)
[root@s35lp76 perf]# perf trace -e open touch /tmp/abc
0.400 ( 0.015 ms): touch/27542 open(filename:
/usr/lib/locale/locale-archive, flags: CLOEXEC) = 3
[root@s35lp76 perf]#
There is no 'open' system call for file '/tmp/abc'. Instead the 'openat'
system call is used:
[root@s35lp76 perf]# strace touch /tmp/abc
execve("/usr/bin/touch", ["touch", "/tmp/abc"], 0x3ffd547ec98
/* 30 vars */) = 0
[...]
openat(AT_FDCWD, "/tmp/abc", O_WRONLY|O_CREAT|O_NOCTTY|O_NONBLOCK, 0666) = 3
[...]
On s390x the 'egrep' command does not find a matching pattern and
returns an error.
Fix this for s390x create a platform dependent command line to enable
the 'perf probe' call to listen to the 'openat' system call and get the
expected output.

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.

From: Andi Kleen <[email protected]>
[ Upstream commit 59622fd496a3175c7bf549046e091d81c303ecff ]
The Intel PMU event aliases have a implicit period= specifier to set the
default period.
Unfortunately this breaks overriding these periods with -c or -F,
because the alias terms look like they are user specified to the
internal parser, and user specified event qualifiers override the
command line options.
Track that they are coming from aliases by adding a "weak" state to the
term. Any weak terms don't override command line options.
I only did it for -c/-F for now, I think that's the only case that's
broken currently.
Before:
$ perf record -c 1000 -vv -e uops_issued.any
...
{ sample_period, sample_freq } 2000003
After:
$ perf record -c 1000 -vv -e uops_issued.any
...
{ sample_period, sample_freq } 1000

Referring TRM Am335X series:
http://www.ti.com/lit/ug/spruh73p/spruh73p.pdf
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.

From: Tony Lindgren <[email protected]>
[ 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.

commit 889c604fd0b5f6d3b8694ade229ee44124de1127 upstream.
syzkaller triggered OOM kills by passing ipt_replace.size = -1
to IPT_SO_SET_REPLACE. The root cause is that SMP_ALIGN() in
xt_alloc_table_info() causes int overflow and the size check passes
when it should not. SMP_ALIGN() is no longer needed leftover.
Remove SMP_ALIGN() call in xt_alloc_table_info().

[ Upstream commit fd00cf81a9a84776ba58e56bd042c726dcf75cf3 ]
The receive_buf callback is supposed to return the number of bytes
processed and should specifically not return a negative errno.
Due to missing sanity checks in the serdev tty-port controller, a driver
not providing a receive_buf callback could cause the flush_to_ldisc()
worker to spin in a tight loop when the tty buffer pointers are
incremented with -EINVAL (-22).
The missing sanity checks have now been added to the tty-port
controller, but let's fix up the serdev-controller helper as well.

From: Tony Lindgren <[email protected]>
[ Upstream commit d09220a887f70368afa79e850c95e74890c0a32d ]
With the CMA changes from Joonsoo Kim <[email protected]>, 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 7d2b8e6aaf9ee87910c2337e1c59bb5d3e3ba8c5 upstream.
Since commit 152a6a884ae1 ("staging:iio:accel:sca3000 move
to hybrid hard / soft buffer design.")
the buffer mechanism has changed and the
INDIO_BUFFER_HARDWARE flag has been unused.
Since commit 2d6ca60f3284 ("iio: Add a DMAengine framework
based buffer")
the INDIO_BUFFER_HARDWARE flag has been re-purposed for
DMA buffers.
This driver has lagged behind these changes, and
in order for buffers to work, the INDIO_BUFFER_SOFTWARE
needs to be used.

The external clock frequency was set only when selecting
the internal clock, which is fixed at 4.9152 Mhz.
This is incorrect, since it should be set when any of
the external clock or crystal settings is selected.
Added range validation for the external (crystal/clock)
frequency setting.
Valid values are between 2.4576 and 5.12 Mhz.

commit a77660d231f8b3d84fd23ed482e0964f7aa546d6 upstream.
Currently KCOV_ENABLE does not check if the current task is already
associated with another kcov descriptor. As the result it is possible
to associate a single task with more than one kcov descriptor, which
later leads to a memory leak of the old descriptor. This relation is
really meant to be one-to-one (task has only one back link).
Extend validation to detect such misuse.

From: Todd Kjos <[email protected]>
commit e46a3b3ba7509cb7fda0e07bc7c63a2cd90f579b upstream.
binder_send_failed_reply() is called when a synchronous
transaction fails. It reports an error to the thread that
is waiting for the completion. Given that the transaction
is synchronous, there should never be more than 1 error
response to that thread -- this was being asserted with
a WARN().
However, when exercising the driver with syzbot tests, cases
were observed where multiple "synchronous" requests were
sent without waiting for responses, so it is possible that
multiple errors would be reported to the thread. This testing
was conducted with panic_on_warn set which forced the crash.
This is easily reproduced by sending back-to-back
"synchronous" transactions without checking for any
response (eg, set read_size to 0):
bwr.write_buffer = (uintptr_t)&bc1;
bwr.write_size = sizeof(bc1);
bwr.read_buffer = (uintptr_t)&br;
bwr.read_size = 0;
ioctl(fd, BINDER_WRITE_READ, &bwr);
sleep(1);
bwr2.write_buffer = (uintptr_t)&bc2;
bwr2.write_size = sizeof(bc2);
bwr2.read_buffer = (uintptr_t)&br;
bwr2.read_size = 0;
ioctl(fd, BINDER_WRITE_READ, &bwr2);
sleep(1);
The first transaction is sent to the servicemanager and the reply
fails because no VMA is set up by this client. After
binder_send_failed_reply() is called, the BINDER_WORK_RETURN_ERROR
is sitting on the thread's todo list since the read_size was 0 and
the client is not waiting for a response.
The 2nd transaction is sent and the BINDER_WORK_RETURN_ERROR has not
been consumed, so the thread's reply_error.cmd is still set (normally
cleared when the BINDER_WORK_RETURN_ERROR is handled). Therefore
when the servicemanager attempts to reply to the 2nd failed
transaction, the error is already set and it triggers this warning.
This is a user error since it is not waiting for the synchronous
transaction to complete. If it ever does check, it will see an
error.
Changed the WARN() to a pr_warn().

commit dfec091439bb2acf763497cfc58f2bdfc67c56b7 upstream.
After commit 3f34cfae1238 ("netfilter: on sockopt() acquire sock lock
only in the required scope"), the caller of nf_{get/set}sockopt() must
not hold any lock, but, in such changeset, I forgot to cope with DECnet.
This commit addresses the issue moving the nf call outside the lock,
in the dn_{get,set}sockopt() with the same schema currently used by
ipv4 and ipv6. Also moves the unhandled sockopts of the end of the main
switch statements, to improve code readability.

commit 40ca54e3a686f13117f3de0c443f8026dadf7c44 upstream.
syzbot reported a lockdep splat in gen_new_estimator() /
est_fetch_counters() when attempting to lock est->stats_lock.
Since est_fetch_counters() is called from BH context from timer
interrupt, we need to block BH as well when calling it from process
context.
Most qdiscs use per cpu counters and are immune to the problem,
but net/sched/act_api.c and net/netfilter/xt_RATEEST.c are using
a spinlock to protect their data. They both call gen_new_estimator()
while object is created and not yet alive, so this bug could
not trigger a deadlock, only a lockdep splat.

commit 8d74e9f88d65af8bb2e095aff506aa6eac755ada upstream.
skb_warn_bad_offload warns when packets enter the GSO stack that
require skb_checksum_help or vice versa. Do not warn on arbitrary
bad packets. Packet sockets can craft many. Syzkaller was able to
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.
See also commit 36c92474498a ("net: WARN if skb_checksum_help() is
called on skb requiring segmentation") for context on this warning.

commit 51a1aaa631c90223888d8beac4d649dc11d2ca55 upstream.
When creating a new radio on the fly, hwsim allows this
to be done with an arbitrary number of channels, but
cfg80211 only supports a limited number of simultaneous
channels, leading to a warning.
Fix this by validating the number - this requires moving
the define for the maximum out to a visible header file.

commit 374d1b5a81f7f9cc5e7f095ac3d5aff3f6600376 upstream.
The GRO layer does not necessarily pull the complete headers
into the linear part of the skb, a part may remain on the
first page fragment. This can lead to a crash if we try to
pull the headers, so make sure we have them on the linear
part before pulling.

This is a warning that validation of the ioctl fields failed. This was
deliberately added as a warning to make it very obvious to developers that
something needed to be fixed. In reality, this is overkill and disturbs
fuzzing. Switch to pr_warn for a message instead.

syzbot reported a warning from rfkill_alloc(), and after a while
I think that the reason is that it was doing fault injection and
the dev_set_name() failed, leaving the name NULL, and we didn't
check the return value and got to rfkill_alloc() with a NULL name.
Since we really don't want a NULL name, we ought to check the
return value.

From: Eric Biggers <[email protected]>
commit d8c7fe9f2a486a6e5f0d5229ca43807af5ab22c6 upstream.
Using %rbp as a temporary register breaks frame pointer convention and
breaks stack traces when unwinding from an interrupt in the crypto code.
In twofish-3way, we can't simply replace %rbp with another register
because there are none available. Instead, we use the stack to hold the
values that %rbp, %r11, and %r12 were holding previously. Each of these
values represents the half of the output from the previous Feistel round
that is being passed on unchanged to the following round. They are only
used once per round, when they are exchanged with %rax, %rbx, and %rcx.
As a result, we free up 3 registers (one per block) and can reassign
them so that %rbp is not used, and additionally %r14 and %r15 are not
used so they do not need to be saved/restored.
There may be a small overhead caused by replacing 'xchg REG, REG' with
the needed sequence 'mov MEM, REG; mov REG, MEM; mov REG, REG' once per
round. But, counterintuitively, when I tested "ctr-twofish-3way" on a
Haswell processor, the new version was actually about 2% faster.
(Perhaps 'xchg' is not as well optimized as plain moves.)

From: Daniel Borkmann <[email protected]>
commit 6f16101e6a8b4324c36e58a29d9e0dbb287cdedb upstream.
syzkaller generated a BPF proglet and triggered a warning with
the following:
0: (b7) r0 = 0
1: (d5) if r0 s<= 0x0 goto pc+0
R0=inv0 R1=ctx(id=0,off=0,imm=0) R10=fp0
2: (1f) r0 -= r1
R0=inv0 R1=ctx(id=0,off=0,imm=0) R10=fp0
verifier internal error: known but bad sbounds
What happens is that in the first insn, r0's min/max value
are both 0 due to the immediate assignment, later in the jsle
test the bounds are updated for the min value in the false
path, meaning, they yield smin_val = 1, smax_val = 0, and when
ctx pointer is subtracted from r0, verifier bails out with the
internal error and throwing a WARN since smin_val != smax_val
for the known constant.
For min_val > max_val scenario it means that reg_set_min_max()
and reg_set_min_max_inv() (which both refine existing bounds)
demonstrated that such branch cannot be taken at runtime.
In above scenario for the case where it will be taken, the
existing [0, 0] bounds are kept intact. Meaning, the rejection
is not due to a verifier internal error, and therefore the
WARN() is not necessary either.
We could just reject such cases in adjust_{ptr,scalar}_min_max_vals()
when either known scalars have smin_val != smax_val or
umin_val != umax_val or any scalar reg with bounds
smin_val > smax_val or umin_val > umax_val. However, there
may be a small risk of breakage of buggy programs, so handle
this more gracefully and in adjust_{ptr,scalar}_min_max_vals()
just taint the dst reg as unknown scalar when we see ops with
such kind of src reg.

commit 4b14752ec4e0d87126e636384cf37c8dd9df157c upstream.
We can't do anything reasonable in security_bounded_transition() if we
don't have a policy loaded, and in fact we could run into problems
with some of the code inside expecting a policy. Fix these problems
like we do many others in security/selinux/ss/services.c by checking
to see if the policy is loaded (ss_initialized) and returning quickly
if it isn't.

commit a6da0024ffc19e0d47712bb5ca4fd083f76b07df upstream.
We need to ensure that tracepoints are registered and unregistered
with the users of them. The existing atomic count isn't enough for
that. Add a lock around the tracepoints, so we serialize access
to them.
This fixes cases where we have multiple users setting up and
tearing down tracepoints, like this:

commit e9cb4239134c860e5f92c75bf5321bd377bb505b upstream.
We used to call mutex_lock() in vhost_dev_lock_vqs() which tries to
hold mutexes of all virtqueues. This may confuse lockdep to report a
possible deadlock because of trying to hold locks belong to same
class. Switch to use mutex_lock_nested() to avoid false positive.

commit 2a4340c57717162c6bf07a0860d05711d4de994b upstream.
As syzkaller spotted, currently line6 drivers submit a URB with the
fixed EP without checking whether it's actually available, which may
result in a kernel warning like:
usb 1-1: BOGUS urb xfer, pipe 3 != type 1

This patch adds a sanity check of validity of EPs at the device

From: Cong Wang <[email protected]>
commit 6a53b7593233ab9e4f96873ebacc0f653a55c3e1 upstream.
syzbot reported a kernel warning in xfrm_state_fini(), which
indicates that we have entries left in the list
net->xfrm.state_all whose proto is zero. And
xfrm_id_proto_match() doesn't consider them as a match with
IPSEC_PROTO_ANY in this case.
Proto with value 0 is probably not a valid value, at least
verify_newsa_info() doesn't consider it valid either.
This patch fixes it by checking the proto value in
validate_tmpl() and rejecting invalid ones, like what iproute2
does in xfrm_xfrmproto_getbyname().

commit b3a0066005821acdc0cdb092cb72587182ab583f upstream.
fsnotify_add_mark_locked() can fail but we do not check its return
value. This didn't matter before commit 9dd813c15b2c "fsnotify: Move
mark list head from object into dedicated structure" as none of possible
failures could happen for dnotify but after that commit -ENOMEM can be
returned. Handle this error properly in fcntl_dirnotify() as
otherwise we just hit BUG_ON(dn_mark->dn) in dnotify_free_mark().

commit d0e312fe3d34c1bc014a7f8ec6540d05e8077483 upstream.
The RDMA netlink core code checks validity of messages by ensuring
that type and operand are in range. It works well for almost all
clients except NLDEV, which has cb_table less than number of operands.
Request to access such operand will trigger the following kernel panic.
This patch updates all places where cb_table is declared for the
consistency, but only NLDEV is actually need it.

From: Steffen Klassert <[email protected]>
commit ddc47e4404b58f03e98345398fb12d38fe291512 upstream.
When we do tunnel or beet mode, we pass saddr and daddr from the
template to xfrm_state_find(), this is ok. On transport mode,
we pass the addresses from the flowi, assuming that the IP
addresses (and address family) don't change during transformation.
This assumption is wrong in the IPv4 mapped IPv6 case, packet
is IPv4 and template is IPv6.
Fix this by catching address family missmatches of the policy
and the flow already before we do the lookup.

----------
Since allowing register_shrinker() callers to call unregister_shrinker()
when register_shrinker() failed can simplify error recovery path, this
patch makes unregister_shrinker() no-op when register_shrinker() failed.
Also, reset shrinker->nr_deferred in case unregister_shrinker() was
by error called twice.

From: Xin Long <[email protected]>
commit ecca8f88da5c4260cc2bccfefd2a24976704c366 upstream.
Now in sctp_setsockopt_maxseg user_frag or frag_point can be set with
val >= 8 and val <= SCTP_MAX_CHUNK_LEN. But both checks are incorrect.
val >= 8 means frag_point can even be less than SCTP_DEFAULT_MINSEGMENT.
Then in sctp_datamsg_from_user(), when it's value is greater than cookie
echo len and trying to bundle with cookie echo chunk, the first_len will
overflow.
The worse case is when it's value is equal as cookie echo len, first_len
becomes 0, it will go into a dead loop for fragment later on. In Hangbin
syzkaller testing env, oom was even triggered due to consecutive memory
allocation in that loop.
Besides, SCTP_MAX_CHUNK_LEN is the max size of the whole chunk, it should
deduct the data header for frag_point or user_frag check.
This patch does a proper check with SCTP_DEFAULT_MINSEGMENT subtracting
the sctphdr and datahdr, SCTP_MAX_CHUNK_LEN subtracting datahdr when
setting frag_point via sockopt. It also improves sctp_setsockopt_maxseg
codes.

commit 2f10a61cee8fdb9f8da90f5db687e1862b22cf06 upstream.
request_module can sleep, thus we cannot hold rcu_read_lock() while
calling it. The function also jumps back and takes rcu_read_lock()
again (in xfrm_state_get_afinfo()), resulting in an imbalance.
This codepath is triggered whenever a new offloaded state is created.
Fixes: ffdb5211da1c ("xfrm: Auto-load xfrm offload modules")

From: Takashi Iwai <[email protected]>
commit e901b9873876ca30a09253731bd3a6b00c44b5b0 upstream.
This patch adds a new helper function to perform a sanity check of the
given URB to see whether it contains a valid endpoint. It's a light-
weight version of what usb_submit_urb() does, but without the kernel
warning followed by the stack trace, just returns an error code.
Especially for a driver that doesn't parse the descriptor but fills
the URB with the fixed endpoint (e.g. some quirks for non-compliant
devices), this kind of check is preferable at the probe phase before
actually submitting the urb.
