tty/serial: digicolor: fix possible null-ptr-deref in digicolor_uart_probe()
commit 447ee1516f19f534a228dda237eddb202f23e163 upstream.
It will cause null-ptr-deref when using 'res', if platform_get_resource()
returns NULL, so move using 'res' after devm_ioremap_resource() that
will check it to avoid null-ptr-deref.
And use devm_platform_get_and_ioremap_resource() to simplify code.

ping: fix address binding wrt vrf
commit e1a7ac6f3ba6e157adcd0ca94d92a401f1943f56 upstream.
When ping_group_range is updated, 'ping' uses the DGRAM ICMP socket,
instead of an IP raw socket. In this case, 'ping' is unable to bind its
socket to a local address owned by a vrflite.
Before the patch:
$ sysctl -w net.ipv4.ping_group_range='0 2147483647'
$ ip link add blue type vrf table 10
$ ip link add foo type dummy
$ ip link set foo master blue
$ ip link set foo up
$ ip addr add 192.168.1.1/24 dev foo
$ ip addr add 2001::1/64 dev foo
$ ip vrf exec blue ping -c1 -I 192.168.1.1 192.168.1.2
ping: bind: Cannot assign requested address
$ ip vrf exec blue ping6 -c1 -I 2001::1 2001::2
ping6: bind icmp socket: Cannot assign requested address

arm[64]/memremap: don't abuse pfn_valid() to ensure presence of linear map
commit 260364d112bc822005224667c0c9b1b17a53eafd upstream.
The semantics of pfn_valid() is to check presence of the memory map for a
PFN and not whether a PFN is covered by the linear map. The memory map
may be present for NOMAP memory regions, but they won't be mapped in the
linear mapping. Accessing such regions via __va() when they are
memremap()'ed will cause a crash.
On v5.4.y the crash happens on qemu-arm with UEFI [1]:

On kernels v5.10.y and newer the same crash won't reproduce on ARM because
commit b10d6bca8720 ("arch, drivers: replace for_each_membock() with
for_each_mem_range()") changed the way memory regions are registered in
the resource tree, but that merely covers up the problem.
On ARM64 memory resources registered in yet another way and there the
issue of wrong usage of pfn_valid() to ensure availability of the linear
map is also covered.
Implement arch_memremap_can_ram_remap() on ARM and ARM64 to prevent access
to NOMAP regions via the linear mapping in memremap().

With the FEC driver phydev->adjust_link() calls fec_enet_adjust_link()
calls fec_stop()/fec_restart() and both these function reset and
temporary disable the FEC disrupting any MII transaction that
could be happening at the same time.
fec_enet_adjust_link() and phy_read() can be running at the same time
when we have one additional interrupt before the phy_state_machine() is
able to terminate.

drm/vmwgfx: Initialize drm_mode_fb_cmd2
commit 3059d9b9f6aa433a55b9d0d21b566396d5497c33 upstream.
Transition to drm_mode_fb_cmd2 from drm_mode_fb_cmd left the structure
unitialized. drm_mode_fb_cmd2 adds a few additional members, e.g. flags
and modifiers which were never initialized. Garbage in those members
can cause random failures during the bringup of the fbcon.
Initializing the structure fixes random blank screens after bootup due
to flags/modifiers mismatches during the fbcon bring up.

cgroup/cpuset: Remove cpus_allowed/mems_allowed setup in cpuset_init_smp()
commit 2685027fca387b602ae565bff17895188b803988 upstream.
There are 3 places where the cpu and node masks of the top cpuset can
be initialized in the order they are executed:
1) start_kernel -> cpuset_init()
2) start_kernel -> cgroup_init() -> cpuset_bind()
3) kernel_init_freeable() -> do_basic_setup() -> cpuset_init_smp()
The first cpuset_init() call just sets all the bits in the masks.
The second cpuset_bind() call sets cpus_allowed and mems_allowed to the
default v2 values. The third cpuset_init_smp() call sets them back to
v1 values.
For systems with cgroup v2 setup, cpuset_bind() is called once. As a
result, cpu and memory node hot add may fail to update the cpu and node
masks of the top cpuset to include the newly added cpu or node in a
cgroup v2 environment.
For systems with cgroup v1 setup, cpuset_bind() is called again by
rebind_subsystem() when the v1 cpuset filesystem is mounted as shown
in the dmesg log below with an instrumented kernel.
[ 2.609781] cpuset_bind() called - v2 = 1
[ 3.079473] cpuset_init_smp() called
[ 7.103710] cpuset_bind() called - v2 = 0
smp_init() is called after the first two init functions. So we don't
have a complete list of active cpus and memory nodes until later in
cpuset_init_smp() which is the right time to set up effective_cpus
and effective_mems.
To fix this cgroup v2 mask setup problem, the potentially incorrect
cpus_allowed & mems_allowed setting in cpuset_init_smp() are removed.
For cgroup v2 systems, the initial cpuset_bind() call will set the masks
correctly. For cgroup v1 systems, the second call to cpuset_bind()
will do the right setup.

i40e: i40e_main: fix a missing check on list iterator
commit 3f95a7472d14abef284d8968734fe2ae7ff4845f upstream.
The bug is here:
ret = i40e_add_macvlan_filter(hw, ch->seid, vdev->dev_addr, &aq_err);
The list iterator 'ch' will point to a bogus position containing
HEAD if the list is empty or no element is found. This case must
be checked before any use of the iterator, otherwise it will
lead to a invalid memory access.
To fix this bug, use a new variable 'iter' as the list iterator,
while use the origin variable 'ch' as a dedicated pointer to
point to the found element.

serial: 8250_mtk: Fix UART_EFR register address
commit bb0b197aadd928f52ce6f01f0ee977f0a08cf1be upstream.
On MediaTek SoCs, the UART IP is 16550A compatible, but there are some
specific quirks: we are declaring a register shift of 2, but this is
only valid for the majority of the registers, as there are some that
are out of the standard layout.
Specifically, this driver is using definitions from serial_reg.h, where
we have a UART_EFR register defined as 2: this results in a 0x8 offset,
but there we have the FCR register instead.
The right offset for the EFR register on MediaTek UART is at 0x98,
so, following the decimal definition convention in serial_reg.h and
accounting for the register left shift of two, add and use the correct
register address for this IP, defined as decimal 38, so that the final
calculation results in (0x26 << 2) = 0x98.

usb: typec: tcpci: Don't skip cleanup in .remove() on error
commit bbc126ae381cf0a27822c1f822d0aeed74cc40d9 upstream.
Returning an error value in an i2c remove callback results in an error
message being emitted by the i2c core, but otherwise it doesn't make a
difference. The device goes away anyhow and the devm cleanups are
called.
In this case the remove callback even returns early without stopping the
tcpm worker thread and various timers. A work scheduled on the work
queue, or a firing timer after tcpci_remove() returned probably results
in a use-after-free situation because the regmap and driver data were
freed. So better make sure that tcpci_unregister_port() is called even
if disabling the irq failed.
Also emit a more specific error message instead of the i2c core's
"remove failed (EIO), will be ignored" and return 0 to suppress the
core's warning.
This patch is (also) a preparation for making i2c remove callbacks
return void.

usb: cdc-wdm: fix reading stuck on device close
commit 01e01f5c89773c600a9f0b32c888de0146066c3a upstream.
cdc-wdm tracks whether a response reading request is in-progress and
blocks the next request from being sent until the previous request is
completed. As soon as last user closes the cdc-wdm device file, the
driver cancels any ongoing requests, resets the pending response
counter, but leaves the response reading in-progress flag
(WDM_RESPONDING) untouched.
So if the user closes the device file during the response receive
request is being performed, no more data will be obtained from the
modem. The request will be cancelled, effectively preventing the
WDM_RESPONDING flag from being reseted. Keeping the flag set will
prevent a new response receive request from being sent, permanently
blocking the read path. The read path will staying blocked until the
module will be reloaded or till the modem will be re-attached.
This stuck has been observed with a Huawei E3372 modem attached to an
OpenWrt router and using the comgt utility to set up a network
connection.
Fix this issue by clearing the WDM_RESPONDING flag on the device file
close.
Without this fix, the device reading stuck can be easily reproduced in a
few connection establishing attempts. With this fix, a load test for
modem connection re-establishing worked for several hours without any
issues.

tty: n_gsm: fix mux activation issues in gsm_config()
commit edd5f60c340086891fab094ad61270d6c80f9ca4 upstream.
The current implementation activates the mux if it was restarted and opens
the control channel if the mux was previously closed and we are now acting
as initiator instead of responder, which is the default setting.
This has two issues.
1) No mux is activated if we keep all default values and only switch to
initiator. The control channel is not allocated but will be opened next
which results in a NULL pointer dereference.
2) Switching the configuration after it was once configured while keeping
the initiator value the same will not reopen the control channel if it was
closed due to parameter incompatibilities. The mux remains dead.
Fix 1) by always activating the mux if it is dead after configuration.
Fix 2) by always opening the control channel after mux activation.

In order to limit the ability for an observer to recognize the source
ports sequence used to contact a set of destinations, we should
periodically shuffle the secret. 10 seconds looks effective enough
without causing particular issues.

net: emaclite: Don't advertise 1000BASE-T and do auto negotiation
[ Upstream commit b800528b97d0adc3a5ba42d78a8b0d3f07a31f44 ]
In xemaclite_open() function we are setting the max speed of
emaclite to 100Mb using phy_set_max_speed() function so,
there is no need to write the advertising registers to stop
giga-bit speed and the phy_start() function starts the
auto-negotiation so, there is no need to handle it separately
using advertising registers. Remove the phy_read and phy_write
of advertising registers in xemaclite_open() function.

s390: disable -Warray-bounds
[ Upstream commit 8b202ee218395319aec1ef44f72043e1fbaccdd6 ]
gcc-12 shows a lot of array bound warnings on s390. This is caused
by the S390_lowcore macro which uses a hardcoded address of 0.
Wrapping that with absolute_pointer() works, but gcc no longer knows
that a 12 bit displacement is sufficient to access lowcore. So it
emits instructions like 'lghi %r1,0; l %rx,xxx(%r1)' instead of a
single load/store instruction. As s390 stores variables often
read/written in lowcore, this is considered problematic. Therefore
disable -Warray-bounds on s390 for gcc-12 for the time being, until
there is a better solution.

When a write cannot be carried out in full, gfs2_iomap_end() releases
blocks that have been allocated for this write but haven't been used.
To compute the end of the allocation, gfs2_iomap_end() incorrectly
rounded the end of the attempted write down to the next block boundary
to arrive at the end of the allocation. It would have to round up, but
the end of the allocation is also available as iomap->offset +
iomap->length, so just use that instead.
In addition, use round_up() for computing the start of the unused range.

net: sfc: ef10: fix memory leak in efx_ef10_mtd_probe()
[ Upstream commit 1fa89ffbc04545b7582518e57f4b63e2a062870f ]
In the NIC ->probe() callback, ->mtd_probe() callback is called.
If NIC has 2 ports, ->probe() is called twice and ->mtd_probe() too.
In the ->mtd_probe(), which is efx_ef10_mtd_probe() it allocates and
initializes mtd partiion.
But mtd partition for sfc is shared data.
So that allocated mtd partition data from last called
efx_ef10_mtd_probe() will not be used.
Therefore it must be freed.
But it doesn't free a not used mtd partition data in efx_ef10_mtd_probe().

net/sched: act_pedit: really ensure the skb is writable
[ Upstream commit 8b796475fd7882663a870456466a4fb315cc1bd6 ]
Currently pedit tries to ensure that the accessed skb offset
is writable via skb_unclone(). The action potentially allows
touching any skb bytes, so it may end-up modifying shared data.
The above causes some sporadic MPTCP self-test failures, due to
this code:
tc -n $ns2 filter add dev ns2eth$i egress \
protocol ip prio 1000 \
handle 42 fw \
action pedit munge offset 148 u8 invert \
pipe csum tcp \
index 100
The above modifies a data byte outside the skb head and the skb is
a cloned one, carrying a TCP output packet.
This change addresses the issue by keeping track of a rough
over-estimate highest skb offset accessed by the action and ensuring
such offset is really writable.
Note that this may cause performance regressions in some scenarios,
but hopefully pedit is not in the critical path.

dim: initialize all struct fields
[ Upstream commit ee1444b5e1df4155b591d0d9b1e72853a99ea861 ]
The W=2 build pointed out that the code wasn't initializing all the
variables in the dim_cq_moder declarations with the struct initializers.
The net change here is zero since these structs were already static
const globals and were initialized with zeros by the compiler, but
removing compiler warnings has value in and of itself.
lib/dim/net_dim.c: At top level:
lib/dim/net_dim.c:54:9: warning: missing initializer for field ‘comps’ of ‘const struct dim_cq_moder’ [-Wmissing-field-initializers]
54 | NET_DIM_RX_EQE_PROFILES,
| ^~~~~~~~~~~~~~~~~~~~~~~
In file included from lib/dim/net_dim.c:6:
./include/linux/dim.h:45:13: note: ‘comps’ declared here
45 | u16 comps;
| ^~~~~
and repeats for the tx struct, and once you fix the comps entry then
the cq_period_mode field needs the same treatment.
Use the commonly accepted style to indicate to the compiler that we
know what we're doing, and add a comma at the end of each struct
initializer to clean up the issue, and use explicit initializers
for the fields we are initializing which makes the compiler happy.
While here and fixing these lines, clean up the code slightly with
a fix for the super long lines by removing the word "_MODERATION" from a
couple defines only used in this file.

drm/nouveau: Fix a potential theorical leak in nouveau_get_backlight_name()
[ Upstream commit ab244be47a8f111bc82496a8a20c907236e37f95 ]
If successful ida_simple_get() calls are not undone when needed, some
additional memory may be allocated and wasted.
Here, an ID between 0 and MAX_INT is required. If this ID is >=100, it is
not taken into account and is wasted. It should be released.
Instead of calling ida_simple_remove(), take advantage of the 'max'
parameter to require the ID not to be too big. Should it be too big, it
is not allocated and don't need to be freed.
While at it, use ida_alloc_xxx()/ida_free() instead to
ida_simple_get()/ida_simple_remove().
The latter is deprecated and more verbose.

The metadata dst is leaked when ip_route_input_mc() updates the dst for
the skb. Commit f38a9eb1f77b ("dst: Metadata destinations") correctly
handled dropping the dst in ip_route_input_slow() but missed the
multicast case which is handled by ip_route_input_mc(). Drop the dst in
ip_route_input_mc() avoiding the leak.

mac80211: Reset MBSSID parameters upon connection
[ Upstream commit 86af062f40a73bf63321694e6bf637144f0383fe ]
Currently MBSSID parameters in struct ieee80211_bss_conf
are not reset upon connection. This could be problematic
with some drivers in a scenario where the device first
connects to a non-transmit BSS and then connects to a
transmit BSS of a Multi BSS AP. The MBSSID parameters
which are set after connecting to a non-transmit BSS will
not be reset and the same parameters will be passed on to
the driver during the subsequent connection to a transmit
BSS of a Multi BSS AP.
For example, firmware running on the ath11k device uses the
Multi BSS data for tracking the beacon of a non-transmit BSS
and reports the driver when there is a beacon miss. If we do
not reset the MBSSID parameters during the subsequent
connection to a transmit BSS, then the driver would have
wrong MBSSID data and FW would be looking for an incorrect
BSSID in the MBSSID beacon of a Multi BSS AP and reports
beacon loss leading to an unstable connection.
Reset the MBSSID parameters upon every connection to solve this
problem.

hwmon: (tmp401) Add OF device ID table
[ Upstream commit 3481551f035725fdc46885425eac3ef9b58ae7b7 ]
This driver doesn't have of_match_table. This makes the kernel module
tmp401.ko lack alias patterns (e.g: of:N*T*Cti,tmp411) to match DT node
of the supported devices hence this kernel module will not be
automatically loaded.
After adding of_match_table to this driver, the folllowing alias will be
added into tmp401.ko.

batman-adv: Don't skb_split skbuffs with frag_list
[ Upstream commit a063f2fba3fa633a599253b62561051ac185fa99 ]
The receiving interface might have used GRO to receive more fragments than
MAX_SKB_FRAGS fragments. In this case, these will not be stored in
skb_shinfo(skb)->frags but merged into the frag list.
batman-adv relies on the function skb_split to split packets up into
multiple smaller packets which are not larger than the MTU on the outgoing
interface. But this function cannot handle frag_list entries and is only
operating on skb_shinfo(skb)->frags. If it is still trying to split such an
skb and xmit'ing it on an interface without support for NETIF_F_FRAGLIST,
then validate_xmit_skb() will try to linearize it. But this fails due to
inconsistent information. And __pskb_pull_tail will trigger a BUG_ON after
skb_copy_bits() returns an error.
In case of entries in frag_list, just linearize the skb before operating on
it with skb_split().
