commit 0c93ac69407d63a85be0129aa55ffaec27ffebd3 upstream.
This does the directory entry name verification for the legacy
"fillonedir" (and compat) interface that goes all the way back to the
dark ages before we had a proper dirent, and the readdir() system call
returned just a single entry at a time.
Nobody should use this interface unless you still have binaries from
1991, but let's do it right.
This came up during discussions about unsafe_copy_to_user() and proper
checking of all the inputs to it, as the networking layer is looking to
use it in a few new places. So let's make sure the _old_ users do it
all right and proper, before we add new ones.
See also commit 8a23eb804ca4 ("Make filldir[64]() verify the directory
entry filename is valid") which did the proper modern interfaces that
people actually use. It had a note:
Note that I didn't bother adding the checks to any legacy interfaces
that nobody uses.
which this now corrects. Note that we really don't care about POSIX and
the presense of '/' in a directory entry, but verify_dirent_name() also
ends up doing the proper name length verification which is what the
input checking discussion was about.
[ Another option would be to remove the support for this particular very
old interface: any binaries that use it are likely a.out binaries, and
they will no longer run anyway since we removed a.out binftm support
in commit eac616557050 ("x86: Deprecate a.out support").
But I'm not sure which came first: getdents() or ELF support, so let's
pretend somebody might still have a working binary that uses the
legacy readdir() case.. ]

commit 8ca7cab82bda4eb0b8064befeeeaa38106cac637 upstream.
commit df7b59ba9245 ("dm verity: fix FEC for RS roots unaligned to
block size") introduced the possibility for misaligned roots IO
relative to the underlying device's logical block size. E.g. Android's
default RS roots=2 results in dm_bufio->block_size=1024, which causes
the following EIO if the logical block size of the device is 4096,
given v->data_dev_block_bits=12:
E sd 0 : 0:0:0: [sda] tag#30 request not aligned to the logical block size
E blk_update_request: I/O error, dev sda, sector 10368424 op 0x0:(READ) flags 0x0 phys_seg 1 prio class 0
E device-mapper: verity-fec: 254:8: FEC 9244672: parity read failed (block 18056): -5
Fix this by onlu using f->roots for dm_bufio blocksize IFF it is
aligned to v->data_dev_block_bits.

commit 276559d8d02c2709281578976ca2f53bc62063d4 upstream.
Valid HID_GENERIC type of devices set EV_KEY and EV_ABS by wacom_map_usage.
When *_input_capabilities are reached, those devices should already have
their proper EV_* set. EV_KEY and EV_ABS only need to be set for
non-HID_GENERIC type of devices in *_input_capabilities.

commit 30b3f68715595dee7fe4d9bd91a2252c3becdf0a upstream.
The touch coordinate register contains the following:
byte 3 byte 2 byte 1
+--------+--------+ +-----------------+ +-----------------+
| | | | | | |
| X[3:0] | Y[3:0] | | Y[11:4] | | X[11:4] |
| | | | | | |
+--------+--------+ +-----------------+ +-----------------+
Bytes 2 and 1 need to be shifted left by 4 bits, the least significant
nibble of each is stored in byte 3. Currently they are only
being shifted by 3 causing the reported coordinates to be incorrect.
This matches downstream examples, and has been confirmed on my
device (OnePlus 7 Pro).

In some race conditions, with more clients and traffic configuration,
below crash is seen when making the interface down. sta->fast_rx wasn't
cleared when STA gets removed from 4-addr AP_VLAN interface. The crash is
due to try accessing 4-addr AP_VLAN interface's net_device (fast_rx->dev)
which has been deleted already.
Resolve this by clearing sta->fast_rx pointer when STA removes
from a 4-addr VLAN.

The clang integrated assembler fails to build one file with
a complex asm instruction:
arch/arm/mach-omap1/ams-delta-fiq-handler.S:249:2: error: invalid instruction, any one of the following would fix this:
mov r10, #(1 << (((NR_IRQS_LEGACY + 12) - NR_IRQS_LEGACY) % 32)) @ set deferred_fiq bit
^
arch/arm/mach-omap1/ams-delta-fiq-handler.S:249:2: note: instruction requires: armv6t2
mov r10, #(1 << (((NR_IRQS_LEGACY + 12) - NR_IRQS_LEGACY) % 32)) @ set deferred_fiq bit
^
arch/arm/mach-omap1/ams-delta-fiq-handler.S:249:2: note: instruction requires: thumb2
mov r10, #(1 << (((NR_IRQS_LEGACY + 12) - NR_IRQS_LEGACY) % 32)) @ set deferred_fiq bit
^
The problem is that 'NR_IRQS_LEGACY' is not defined here. Apparently
gas does not care because we first add and then subtract this number,
leading to the immediate value to be the same regardless of the
specific definition of NR_IRQS_LEGACY.
Neither the way that 'gas' just silently builds this file, nor the
way that clang IAS makes nonsensical suggestions for how to fix it
is great. Fortunately there is an easy fix, which is to #include
the header that contains the definition.

After a short network outage, the dst_entry is timed out and put
in DST_OBSOLETE_DEAD. We are in this code because arp reply comes
from this neighbour after network recovers. There is a potential
race condition that dst_entry is still in DST_OBSOLETE_DEAD.
With that, another neighbour lookup causes more harm than good.
In best case all packets in arp_queue are lost. This is
counterproductive to the original goal of finding a better path
for those packets.
I observed a worst case with 4.x kernel where a dst_entry in
DST_OBSOLETE_DEAD state is associated with loopback net_device.
It leads to an ethernet header with all zero addresses.
A packet with all zero source MAC address is quite deadly with
mac80211, ath9k and 802.11 block ack. It fails
ieee80211_find_sta_by_ifaddr in ath9k (xmit.c). Ath9k flushes tx
queue (ath_tx_complete_aggr). BAW (block ack window) is not
updated. BAW logic is damaged and ath9k transmission is disabled.

In function displback_changed, has the call chain
displback_connect(front_info)->xen_drm_drv_init(front_info).
We can see that drm_info is assigned to front_info->drm_info
and drm_info is freed in fail branch in xen_drm_drv_init().
Later displback_disconnect(front_info) is called and it calls
xen_drm_drv_fini(front_info) cause a use after free by

My patch has done two things. First fixes the fail label which
drm_info = kzalloc() failed and still free the drm_info.
Second sets front_info->drm_info to NULL to avoid uaf.

0x20FF(amp global enable) register was defined as non-volatile,
but it is not. Overheating, overcurrent can cause amp shutdown

'regmap_write' compare register readback value before writing

When amp is internally shutdown by some reason, next 'AMP ON'
command can be ignored because regmap think amp is already ON.

BEET mode replaces the IP(6) Headers with new IP(6) Headers when sending
packets. However, when it's a fragment before the replacement, currently
kernel keeps the fragment flag and replace the address field then encaps
it with ESP. It would cause in RX side the fragments to get reassembled
before decapping with ESP, which is incorrect.
In Xiumei's testing, these fragments went over an xfrm interface and got
encapped with ESP in the device driver, and the traffic was broken.
I don't have a good way to fix it, but only to warn this out in dmesg.

In the first list_for_each_entry() macro of dma_async_device_register,
it gets the chan from list and calls __dma_async_device_channel_register
(..,chan). We can see that chan->local is allocated by alloc_percpu() and
it is freed chan->local by free_percpu(chan->local) when
__dma_async_device_channel_register() failed.
But after __dma_async_device_channel_register() failed, the caller will
goto err_out and freed the chan->local in the second time by free_percpu().
The cause of this problem is forget to set chan->local to NULL when
chan->local was freed in __dma_async_device_channel_register(). My
patch sets chan->local to NULL when the callee failed to avoid double free.
