From: Yoshihiro Shimoda <[email protected]>
commit e6839c31a608e79f2057fab987dd814f5d3477e6 upstream.
The hardware manual should be revised, but the initial value of
VBCTRL.OCCLREN is set to 1 actually. If the bit is set, the hardware
clears VBCTRL.VBOUT and ADPCTRL.DRVVBUS registers automatically
when the hardware detects over-current signal from a USB power switch.
However, since the hardware doesn't have any registers which
indicates over-current, the driver cannot handle it at all. So, if
"is_otg_channel" hardware detects over-current, since ADPCTRL.DRVVBUS
register is cleared automatically, the channel cannot be used after
that.
To resolve this behavior, this patch sets the VBCTRL.OCCLREN to 0
to keep ADPCTRL.DRVVBUS even if the "is_otg_channel" hardware
detects over-current. (We assume a USB power switch itself protects
over-current and turns the VBUS off.)
This patch is inspired by a BSP patch from Kazuya Mizuguchi.

From: Hung-Te Lin <[email protected]>
commit 4b708b7b1a2c09fbdfff6b942ebe3a160213aacd upstream.
The VPD implementation from Chromium Vital Product Data project used to
parse data from untrusted input without checking if the meta data is
invalid or corrupted. For example, the size from decoded content may
be negative value, or larger than whole input buffer. Such invalid data
may cause buffer overflow.
To fix that, the size parameters passed to vpd_decode functions should
be changed to unsigned integer (u32) type, and the parsing of entry
header should be refactored so every size field is correctly verified
before starting to decode.

commit 7caac62ed598a196d6ddf8d9c121e12e082cac3a upstream.
mwifiex_update_vs_ie(),mwifiex_set_uap_rates() and
mwifiex_set_wmm_params() call memcpy() without checking
the destination size.Since the source is given from
user-space, this may trigger a heap buffer overflow.
Fix them by putting the length check before performing memcpy().
This fix addresses CVE-2019-14814,CVE-2019-14815,CVE-2019-14816.

commit 1222a1601488 ("nl80211: Fix possible Spectre-v1 for CQM
RSSI thresholds") was incomplete and requires one more fix to
prevent accessing to rssi_thresholds[n] because user can control
rssi_thresholds[i] values to make i reach to n. For example,
rssi_thresholds = {-400, -300, -200, -100} when last is -34.

TRM says PWMSS_SYSCONFIG bit for SOFTRESET changes to zero when
reset is completed. Let's configure it as otherwise we get warnings
on boot when we check the data against dts provided data. Eventually
the legacy platform data will be just dropped, but let's fix the
warning first.

commit 0c043d70d04711fe6c380df9065fdc44192c49bf upstream.
Looks like the Bios of the Lenovo Legion Y7000 is using ELAN061B
when the actual device is supposed to be used with hid-multitouch.
Remove it from the list of the supported device, hoping that
no one will complain about the loss in functionality.

[ Upstream commit fb59ee37cfe20d10d19568899d1458a58361246c ]
If UHS speed modes are enabled, a compatible SD card switches down to
1.8V during enumeration. If after this a software reboot/crash takes
place and on-chip ROM tries to enumerate the SD card, the difference in
IO voltages (host @ 3.3V and card @ 1.8V) may end up damaging the card.
The fix for this is to have support for power cycling the card in
hardware (with a PORz/soft-reset line causing a power cycle of the
card). Because the beaglebone X15 (rev A,B and C), am57xx-idks and
am57xx-evms don't have this capability, disable voltage switching for
these boards.
The major effect of this is that the maximum supported speed
mode is now high speed(50 MHz) down from SDR104(200 MHz).
commit 88a748419b84 ("ARM: dts: am57xx-idk: Remove support for voltage
switching for SD card") did this only for idk boards. Do it for all
affected boards.

commit 9c801e313195addaf11c16e155f50789d6ebfd19 upstream.
The sequence of arguments which was passed to handle_lsr_errors() didn't
match the parameters defined in that function, &lsr was passed to flag
and &flag was passed to lsr, this patch fixed that.

[ Upstream commit 00b368502d18f790ab715e055869fd4bb7484a9b ]
When skb_shinfo(skb) is not able to cache extra fragment (that is,
skb_shinfo(skb)->nr_frags >= MAX_SKB_FRAGS), xennet_fill_frags() assumes
the sk_buff_head list is already empty. As a result, cons is increased only
by 1 and returns to error handling path in xennet_poll().
However, if the sk_buff_head list is not empty, queue->rx.rsp_cons may be
set incorrectly. That is, queue->rx.rsp_cons would point to the rx ring
buffer entries whose queue->rx_skbs[i] and queue->grant_rx_ref[i] are
already cleared to NULL. This leads to NULL pointer access in the next
iteration to process rx ring buffer entries.
Below is how xennet_poll() does error handling. All remaining entries in
tmpq are accounted to queue->rx.rsp_cons without assuming how many
outstanding skbs are remained in the list.
985 static int xennet_poll(struct napi_struct *napi, int budget)
... ...
1032 if (unlikely(xennet_set_skb_gso(skb, gso))) {
1033 __skb_queue_head(&tmpq, skb);
1034 queue->rx.rsp_cons += skb_queue_len(&tmpq);
1035 goto err;
1036 }
It is better to always have the error handling in the same way.

commit 184eccd40389df29abefab88092c4ff33191fd0c upstream.
In the generic code path, HID_DG_CONTACTMAX was previously
only read from the second byte of report 0x23.
Another report (0x82) has the HID_DG_CONTACTMAX in the
higher nibble of the third byte. We should support reading the
value of HID_DG_CONTACTMAX no matter what report we are reading
or which position that value is in.
To do this we submit the feature report as a event report
using hid_report_raw_event(). Our modified finger event path
records the value of HID_DG_CONTACTMAX when it sees that usage.

When running a 64-bit kernel with a 32-bit iptables binary, the size of
the xt_nfacct_match_info struct diverges.
kernel: sizeof(struct xt_nfacct_match_info) : 40
iptables: sizeof(struct xt_nfacct_match_info)) : 36
Trying to append nfacct related rules results in an unhelpful message.
Although it is suggested to look for more information in dmesg, nothing
can be found there.
# iptables -A <chain> -m nfacct --nfacct-name <acct-object>
iptables: Invalid argument. Run `dmesg' for more information.
This patch fixes the memory misalignment by enforcing 8-byte alignment
within the struct's first revision. This solution is often used in many
other uapi netfilter headers.

Currently, we are translating RPC level errors such as timeouts,
as well as interrupts etc into EOPENSTALE, which forces a single
replay of the open attempt. What we actually want to do is
force the replay only in the cases where the returned error
indicates that the file may have changed on the server.
So the fix is to spell out the exact set of errors where we want
to return EOPENSTALE.

We use mmu_vmemmap_psize to find the page size for mapping the vmmemap area.
With radix translation, we are suboptimally setting this value to PAGE_SIZE.
We do check for 2M page size support and update mmu_vmemap_psize to use
hugepage size but we suboptimally reset the value to PAGE_SIZE in
radix__early_init_mmu(). This resulted in always mapping vmemmap area with
64K page size.

Multiple batadv_ogm2_packet can be stored in an skbuff. The functions
batadv_v_ogm_send_to_if() uses batadv_v_ogm_aggr_packet() to check if there
is another additional batadv_ogm2_packet in the skb or not before they
continue processing the packet.
The length for such an OGM2 is BATADV_OGM2_HLEN +
batadv_ogm2_packet->tvlv_len. The check must first check that at least
BATADV_OGM2_HLEN bytes are available before it accesses tvlv_len (which is
part of the header. Otherwise it might try read outside of the currently

When refactoring port lookup for DSS outputs, commit d17eb4537a7e
("drm/omap: Factor out common init/cleanup code for output devices")
incorrectly hardcoded usage of DT port 0. This breaks operation for SDI
(which uses the DT port 1) and DPI outputs other than DPI0 (which are
not used in mainline DT sources).
Fix this by using the port number from the output omap_dss_device
of_ports field.

A timing hazard exists when an early fork/exec thread begins
exiting and sets its mm pointer to NULL while a separate core
tries to update the section information.
This commit ensures that the mm pointer is not NULL before
setting its section parameters. The arguments provided by
commit 11ce4b33aedc ("ARM: 8672/1: mm: remove tasklist locking
from update_sections_early()") are equally valid for not
requiring grabbing the task_lock around this check.

[ Upstream commit 2c238177bd7f4b14bdf7447cc1cd9bb791f147e6 ]
test_select_reuseport fails on s390 due to verifier rejecting
test_select_reuseport_kern.o with the following message:
; data_check.eth_protocol = reuse_md->eth_protocol;
18: (69) r1 = *(u16 *)(r6 +22)
invalid bpf_context access off=22 size=2
This is because on big-endian machines casts from __u32 to __u16 are
generated by referencing the respective variable as __u16 with an offset
of 2 (as opposed to 0 on little-endian machines).
The verifier already has all the infrastructure in place to allow such
accesses, it's just that they are not explicitly enabled for
eth_protocol field. Enable them for eth_protocol field by using
bpf_ctx_range instead of offsetof.
Ditto for ip_protocol, bind_inany and len, since they already allow
narrowing, and the same problem can arise when working with them.

Non-serio path of Amstrad Delta FIQ deferred handler depended on
irq_ack() method provided by OMAP GPIO driver. That method has been
removed by commit 693de831c6e5 ("gpio: omap: remove irq_ack method").
Remove useless code from the deferred handler and reimplement the
missing operation inside the base FIQ handler.
Should another dependency - irq_unmask() - be ever removed from the OMAP
GPIO driver, WARN once if missing.

From: Thomas Falcon <[email protected]>
[ Upstream commit 36f1031c51a2538e5558fb44c6d6b88f98d3c0f2 ]
Currently, the ibmvnic driver will not schedule device resets
if the device is being removed, but does not check the device
state before the reset is actually processed. This leads to a race
where a reset is scheduled with a valid device state but is
processed after the driver has been removed, resulting in an oops.
Fix this by checking the device state before processing a queued
reset event.

2.20.1
From: Kim Phillips <[email protected]>
[ Upstream commit 0f4cd769c410e2285a4e9873a684d90423f03090 ]
When counting dispatched micro-ops with cnt_ctl=1, in order to prevent
sample bias, IBS hardware preloads the least significant 7 bits of
current count (IbsOpCurCnt) with random values, such that, after the
interrupt is handled and counting resumes, the next sample taken
will be slightly perturbed.
The current count bitfield is in the IBS execution control h/w register,
alongside the maximum count field.
Currently, the IBS driver writes that register with the maximum count,
leaving zeroes to fill the current count field, thereby overwriting
the random bits the hardware preloaded for itself.
Fix the driver to actually retain and carry those random bits from the
read of the IBS control register, through to its write, instead of
overwriting the lower current count bits with zeroes.
Tested with:
perf record -c 100001 -e ibs_op/cnt_ctl=1/pp -a -C 0 taskset -c 0 <workload>
'perf annotate' output before:
15.70 65: addsd %xmm0,%xmm1
17.30 add $0x1,%rax
15.88 cmp %rdx,%rax
je 82

8.30 movapd %xmm1,%xmm0
8.13 jmp 65
8.24 7c: sqrtsd %xmm1,%xmm0
8.39 jmp 65
Tested on Family 15h and 17h machines.
Machines prior to family 10h Rev. C don't have the RDWROPCNT capability,
and have the IbsOpCurCnt bitfield reserved, so this patch shouldn't
affect their operation.
It is unknown why commit db98c5faf8cb ("perf/x86: Implement 64-bit
counter support for IBS") ignored the lower 4 bits of the IbsOpCurCnt
field; the number of preloaded random bits has always been 7, AFAICT.

[ Upstream commit 03531482402a2bc4ab93cf6dde46833775e035e9 ]
The -w argument in x86_energy_perf_policy currently triggers an
unconditional segfault.
This is because the argument string reads: "+a:c:dD:E:e:f:m:M:rt:u:vw" and
yet the argument handler expects an argument.
When parse_optarg_string is called with a null argument, we then proceed to
crash in strncmp, not horribly friendly.
The man page describes -w as taking an argument, the long form
(--hwp-window) is correctly marked as taking a required argument, and the
code expects it.
As such, this patch simply marks the short form (-w) as requiring an
argument.

turbostat could be terminated by general protection fault on some latest
hardwares which (for example) support 9 levels of C-states and show 18
"tADDED" lines. That bloats the total output and finally causes buffer
overrun. So let's extend the buffer to avoid this.

[ Upstream commit 1e9042b9c8d46ada9ee7b3339a31f50d12e5d291 ]
In some case C1% will be wrong value, when platform doesn't have MSR for
C1 residency.
For example:
Core CPU CPU%c1
- - 100.00
0 0 100.00
0 2 100.00
1 1 100.00
1 3 100.00
But adding Busy% will fix this
Core CPU Busy% CPU%c1
- - 99.77 0.23
0 0 99.77 0.23
0 2 99.77 0.23
1 1 99.77 0.23
1 3 99.77 0.23
This issue can be reproduced on most of the recent systems including
Broadwell, Skylake and later.
This is because if we don't select Busy% or Avg_MHz or Bzy_MHz then
mperf value will not be read from MSR, so it will be 0. But this
is required for C1% calculation when MSR for C1 residency is not present.
Same is true for C3, C6 and C7 column selection.
So add another define DO_BIC_READ(), which doesn't depend on user
column selection and use for mperf, C3, C6 and C7 related counters.
So when there is no platform support for C1 residency counters,
we still read these counters, if the CPU has support and user selected
display of CPU%c1.

makes no check for this and something like the following oops may occur:
BUG: Kernel NULL pointer dereference at 0x00000038
Faulting instruction address: 0xc0000000004ddf30
Oops: Kernel access of bad area, sig: 11 [#1]

2.20.1
From: Amir Goldstein <[email protected]>
commit 0be0bfd2de9dfdd2098a9c5b14bdd8f739c9165d upstream.
Once upon a time, commit 2cac0c00a6cd ("ovl: get exclusive ownership on
upper/work dirs") in v4.13 added some sanity checks on overlayfs layers.
This change caused a docker regression. The root cause was mount leaks
by docker, which as far as I know, still exist.
To mitigate the regression, commit 85fdee1eef1a ("ovl: fix regression
caused by exclusive upper/work dir protection") in v4.14 turned the
mount errors into warnings for the default index=off configuration.
Recently, commit 146d62e5a586 ("ovl: detect overlapping layers") in
v5.2, re-introduced exclusive upper/work dir checks regardless of
index=off configuration.
This changes the status quo and mount leak related bug reports have
started to re-surface. Restore the status quo to fix the regressions.
To clarify, index=off does NOT relax overlapping layers check for this
ovelayfs mount. index=off only relaxes exclusive upper/work dir checks
with another overlayfs mount.
To cover the part of overlapping layers detection that used the
exclusive upper/work dir checks to detect overlap with self upper/work
dir, add a trap also on the work base dir.

[ Upstream commit 5c47e3ba6fe52465603cf9d816b3371e6881d649 ]
Declaring threaded irq handler should also indicate the irq is
oneshot. It is oneshot indeed, because HW implements irq automasking
on trigger.
Not declaring this causes some kernel configurations to fail
on interface up, because request_threaded_irq returned an err code.
The issue was originally hidden on normal x86_64 configuration with
latest kernel, because depending on interrupt controller, irq driver
added ONESHOT flag on its own.
Issue was observed on older kernels (4.14) where no such logic exists.

[ Upstream commit 36b7200f67dfe75b416b5281ed4ace9927b513bc ]
When devices are attached to the amd_iommu in a kdump kernel, the old device
table entries (DTEs), which were copied from the crashed kernel, will be
overwritten with a new domain number. When the new DTE is written, the IOMMU
is told to flush the DTE from its internal cache--but it is not told to flush
the translation cache entries for the old domain number.
Without this patch, AMD systems using the tg3 network driver fail when kdump
tries to save the vmcore to a network system, showing network timeouts and
(sometimes) IOMMU errors in the kernel log.
This patch will flush IOMMU translation cache entries for the old domain when
a DTE gets overwritten with a new domain number.

Currently there are two nodes named "regulator1" in the Draak DTS: a
3.3V regulator for the eMMC and the LVDS decoder, and a 12V regulator
for the backlight. This causes the former to be overwritten by the
latter.
Fix this by renaming all regulators with numerical suffixes to use named
suffixes, which are less likely to conflict.

From: Will Deacon <[email protected]>
commit d0b7a302d58abe24ed0f32a0672dd4c356bb73db upstream.
This reverts commit 24fe1b0efad4fcdd32ce46cffeab297f22581707.
Commit 24fe1b0efad4fcdd ("arm64: Remove unnecessary ISBs from
set_{pte,pmd,pud}") removed ISB instructions immediately following updates
to the page table, on the grounds that they are not required by the
architecture and a DSB alone is sufficient to ensure that subsequent data
accesses use the new translation:
DDI0487E_a, B2-128:
| ... no instruction that appears in program order after the DSB
| instruction can alter any state of the system or perform any part of
| its functionality until the DSB completes other than:
|
| * Being fetched from memory and decoded
| * Reading the general-purpose, SIMD and floating-point,
| Special-purpose, or System registers that are directly or indirectly
| read without causing side-effects.
However, the same document also states the following:
DDI0487E_a, B2-125:
| DMB and DSB instructions affect reads and writes to the memory system
| generated by Load/Store instructions and data or unified cache
| maintenance instructions being executed by the PE. Instruction fetches
| or accesses caused by a hardware translation table access are not
| explicit accesses.
which appears to claim that the DSB alone is insufficient. Unfortunately,
some CPU designers have followed the second clause above, whereas in Linux
we've been relying on the first. This means that our mapping sequence:
MOV X0, <valid pte>
STR X0, [Xptep] // Store new PTE to page table
DSB ISHST
LDR X1, [X2] // Translates using the new PTE
can actually raise a translation fault on the load instruction because the
translation can be performed speculatively before the page table update and
then marked as "faulting" by the CPU. For user PTEs, this is ok because we
can handle the spurious fault, but for kernel PTEs and intermediate table
entries this results in a panic().
Revert the offending commit to reintroduce the missing barriers.

[ Upstream commit be6cef69ba570ebb327eba1ef6438f7af49aaf86 ]
On embedded environments with hard memory limits it is a normal although
rare case when skb can't be allocated on rx part under high traffic.
In such OOM cases napi_complete_done() was not called.
So the napi object became in an invalid state like it is "scheduled".
Kernel do not re-schedules the poll of that napi object.
Consequently, kernel can not remove that object the system hangs on
`ifconfig down` waiting for a poll.
We are fixing this by gracefully closing napi poll routine with correct
invocation of napi_complete_done.
This was reproduced with artificially failing the allocation of skb to
simulate an "out of memory" error case and check that traffic does
not get stuck.

After the conversion to lock-less dma-api call the
increase_address_space() function can be called without any
locking. Multiple CPUs could potentially race for increasing
the address space, leading to invalid domain->mode settings
and invalid page-tables. This has been happening in the wild
under high IO load and memory pressure.
Fix the race by locking this operation. The function is
called infrequently so that this does not introduce
a performance regression in the dma-api path again.

[ Upstream commit d518d2ed8640c1cbbbb6f63939e3e65471817367 ]
The test implemented by some_qdisc_is_busy() is somewhat loosy for
NOLOCK qdisc, as we may hit the following scenario:
CPU1 CPU2
// in net_tx_action()
clear_bit(__QDISC_STATE_SCHED...);
// in some_qdisc_is_busy()
val = (qdisc_is_running(q) ||
test_bit(__QDISC_STATE_SCHED,
&q->state));
// here val is 0 but...
qdisc_run(q)
// ... CPU1 is going to run the qdisc next
As a conseguence qdisc_run() in net_tx_action() can race with qdisc_reset()
in dev_qdisc_reset(). Such race is not possible for !NOLOCK qdisc as
both the above bit operations are under the root qdisc lock().
After commit 021a17ed796b ("pfifo_fast: drop unneeded additional lock on dequeue")
the race can cause use after free and/or null ptr dereference, but the root
cause is likely older.
This patch addresses the issue explicitly checking for deactivation under
the seqlock for NOLOCK qdisc, so that the qdisc_run() in the critical
scenario becomes a no-op.
Note that the enqueue() op can still execute concurrently with dev_qdisc_reset(),
but that is safe due to the skb_array() locking, and we can't avoid that
for NOLOCK qdiscs.
Fixes: 021a17ed796b ("pfifo_fast: drop unneeded additional lock on dequeue")

[ Upstream commit 23426a25e55a417dc104df08781b6eff95e65f3f ]
The DSA core, DSA taggers and DSA drivers all make use of
module_init(). Hence they get initialised at device_initcall() time.
The ordering is non-deterministic. It can be a DSA driver is bound to
a device before the needed tag driver has been initialised, resulting
in the message:
No tagger for this switch
Rather than have this be fatal, return -EPROBE_DEFER so that it is
tried again later once all the needed drivers have been loaded.

be freed on the tx_err path. Otherwise when deleting a netns, it would
cause dst/dev to leak, and dmesg shows:
