net/mlx5: Devcom, fix error flow in mlx5_devcom_register_device
commit af87194352cad882d787d06fb7efa714acd95427 upstream.
In case devcom allocation is failed, mlx5 is always freeing the priv.
However, this priv might have been allocated by a different thread,
and freeing it might lead to use-after-free bugs.
Fix it by freeing the priv only in case it was allocated by the
running thread.

xen/pvcalls-back: fix double frees with pvcalls_new_active_socket()
commit 8fafac202d18230bb9926bda48e563fd2cce2a4f upstream.
In the pvcalls_new_active_socket() function, most error paths call
pvcalls_back_release_active(fedata->dev, fedata, map) which calls
sock_release() on "sock". The bug is that the caller also frees sock.
Fix this by making every error path in pvcalls_new_active_socket()
release the sock, and don't free it in the caller.

coresight: Fix signedness bug in tmc_etr_buf_insert_barrier_packet()
commit f67bc15e526bb9920683ad6c1891ff9e08981335 upstream.
This code generates a Smatch warning:
drivers/hwtracing/coresight/coresight-tmc-etr.c:947 tmc_etr_buf_insert_barrier_packet()
error: uninitialized symbol 'bufp'.
The problem is that if tmc_sg_table_get_data() returns -EINVAL, then
when we test if "len < CORESIGHT_BARRIER_PKT_SIZE", the negative "len"
value is type promoted to a high unsigned long value which is greater
than CORESIGHT_BARRIER_PKT_SIZE. Fix this bug by adding an explicit
check for error codes.

power: supply: bq27xxx: Fix poll_interval handling and races on remove
commit c00bc80462afc7963f449d7f21d896d2f629cacc upstream.
Before this patch bq27xxx_battery_teardown() was setting poll_interval = 0
to avoid bq27xxx_battery_update() requeuing the delayed_work item.
There are 2 problems with this:
1. If the driver is unbound through sysfs, rather then the module being
rmmod-ed, this changes poll_interval unexpectedly
2. This is racy, after it being set poll_interval could be changed
before bq27xxx_battery_update() checks it through
/sys/module/bq27xxx_battery/parameters/poll_interval
Fix this by added a removed attribute to struct bq27xxx_device_info and
using that instead of setting poll_interval to 0.
There also is another poll_interval related race on remove(), writing
/sys/module/bq27xxx_battery/parameters/poll_interval will requeue
the delayed_work item for all devices on the bq27xxx_battery_devices
list and the device being removed was only removed from that list
after cancelling the delayed_work item.
Fix this by moving the removal from the bq27xxx_battery_devices list
to before cancelling the delayed_work item.

power: supply: bq27xxx: Fix I2C IRQ race on remove
commit 444ff00734f3878cd54ddd1ed5e2e6dbea9326d5 upstream.
devm_request_threaded_irq() requested IRQs are only free-ed after
the driver's remove function has ran. So the IRQ could trigger and
call bq27xxx_battery_update() after bq27xxx_battery_teardown() has
already run.
Switch to explicitly free-ing the IRQ in bq27xxx_battery_i2c_remove()
to fix this.

power: supply: bq27xxx: Fix bq27xxx_battery_update() race condition
commit 5c34c0aef185dcd10881847b9ebf20046aa77cb4 upstream.
bq27xxx_battery_update() assumes / requires that it is only run once,
not multiple times at the same time. But there are 3 possible callers:
1. bq27xxx_battery_poll() delayed_work item handler
2. bq27xxx_battery_irq_handler_thread() I2C IRQ handler
3. bq27xxx_battery_setup()
And there is no protection against these racing with each other,
fix this race condition by making all callers take di->lock:
- Rename bq27xxx_battery_update() to bq27xxx_battery_update_unlocked()
- Add new bq27xxx_battery_update() which takes di->lock and then calls
bq27xxx_battery_update_unlocked()
- Make stale cache check code in bq27xxx_battery_get_property(), which
already takes di->lock directly to check the jiffies, call
bq27xxx_battery_update_unlocked() instead of messing with
the delayed_work item
- Make bq27xxx_battery_update_unlocked() mod the delayed-work item
so that the next poll is delayed to poll_interval milliseconds after
the last update independent of the source of the update

power: supply: leds: Fix blink to LED on transition
commit e4484643991e0f6b89060092563f0dbab9450cbb upstream.
When a battery's status changes from charging to full then
the charging-blink-full-solid trigger tries to change
the LED from blinking to solid/on.
As is documented in include/linux/leds.h to deactivate blinking /
to make the LED solid a LED_OFF must be send:
"""
* Deactivate blinking again when the brightness is set to LED_OFF
* via the brightness_set() callback.
"""
led_set_brighness() calls with a brightness value other then 0 / LED_OFF
merely change the brightness of the LED in its on state while it is
blinking.
So power_supply_update_bat_leds() must first send a LED_OFF event
before the LED_FULL to disable blinking.

bpf: Fix mask generation for 32-bit narrow loads of 64-bit fields
commit 0613d8ca9ab382caabe9ed2dceb429e9781e443f upstream.
A narrow load from a 64-bit context field results in a 64-bit load
followed potentially by a 64-bit right-shift and then a bitwise AND
operation to extract the relevant data.
In the case of a 32-bit access, an immediate mask of 0xffffffff is used
to construct a 64-bit BPP_AND operation which then sign-extends the mask
value and effectively acts as a glorified no-op. For example:
0: 61 10 00 00 00 00 00 00 r0 = *(u32 *)(r1 + 0)
results in the following code generation for a 64-bit field:
ldr x7, [x7] // 64-bit load
mov x10, #0xffffffffffffffff
and x7, x7, x10
Fix the mask generation so that narrow loads always perform a 32-bit AND
operation:
ldr x7, [x7] // 64-bit load
mov w10, #0xffffffff
and w7, w7, w10

Tests passed: 201
Tests failed: 0
Cannot remove namespace file "/run/netns/ns1": No such file or directory
This can even be reproduced with just `./fib_tests.sh -h` as we're
calling cleanup() on exit.
Redirect the error message to /dev/null to mute it.
V2: Update commit message and fixes tag.
V3: resubmit due to missing netdev ML in V2

net: fix skb leak in __skb_tstamp_tx()
commit 8a02fb71d7192ff1a9a47c9d937624966c6e09af upstream.
Commit 50749f2dd685 ("tcp/udp: Fix memleaks of sk and zerocopy skbs with
TX timestamp.") added a call to skb_orphan_frags_rx() to fix leaks with
zerocopy skbs. But it ended up adding a leak of its own. When
skb_orphan_frags_rx() fails, the function just returns, leaking the skb
it just cloned. Free it before returning.
This bug was discovered and resolved using Coverity Static Analysis
Security Testing (SAST) by Synopsys, Inc.

USB: core: Add routines for endpoint checks in old drivers
commit 13890626501ffda22b18213ddaf7930473da5792 upstream. Many of the older USB drivers in the Linux USB stack were written based simply on a vendor's device specification. They use the endpoint information in the spec and assume these endpoints will always be present, with the properties listed, in any device matching the given vendor and product IDs. While that may have been true back then, with spoofing and fuzzing it is not true any more. More and more we are finding that those old drivers need to perform at least a minimum of checking before they try to use any endpoint other than ep0. To make this checking as simple as possible, we now add a couple of utility routines to the USB core. usb_check_bulk_endpoints() and usb_check_int_endpoints() take an interface pointer together with a list of endpoint addresses (numbers and directions). They check that the interface's current alternate setting includes endpoints with those addresses and that each of these endpoints has the right type: bulk or interrupt, respectively. Although we already have usb_find_common_endpoints() and related routines meant for a similar purpose, they are not well suited for this kind of checking. Those routines find endpoints of various kinds, but only one (either the first or the last) of each kind, and they don't verify that the endpoints' addresses agree with what the caller expects. In theory the new routines could be more general: They could take a particular altsetting as their argument instead of always using the interface's current altsetting. In practice I think this won't matter too much; multiple altsettings tend to be used for transferring media (audio or visual) over isochronous endpoints, not bulk or interrupt. Drivers for such devices will generally require more sophisticated checking than these simplistic routines provide.

net: fix stack overflow when LRO is disabled for virtual interfaces
commit ae9b15fbe63447bc1d3bba3769f409d17ca6fdf6 upstream.
When the virtual interface's feature is updated, it synchronizes the
updated feature for its own lower interface.
This propagation logic should be worked as the iteration, not recursively.
But it works recursively due to the netdev notification unexpectedly.
This problem occurs when it disables LRO only for the team and bonding
interface type.
team0
|
+------+------+-----+-----+
| | | | |
team1 team2 team3 ... team200
If team0's LRO feature is updated, it generates the NETDEV_FEAT_CHANGE
event to its own lower interfaces(team1 ~ team200).
It is worked by netdev_sync_lower_features().
So, the NETDEV_FEAT_CHANGE notification logic of each lower interface
work iteratively.
But generated NETDEV_FEAT_CHANGE event is also sent to the upper
interface too.
upper interface(team0) generates the NETDEV_FEAT_CHANGE event for its own
lower interfaces again.
lower and upper interfaces receive this event and generate this
event again and again.
So, the stack overflow occurs.
But it is not the infinite loop issue.
Because the netdev_sync_lower_features() updates features before
generating the NETDEV_FEAT_CHANGE event.
Already synchronized lower interfaces skip notification logic.
So, it is just the problem that iteration logic is changed to the
recursive unexpectedly due to the notification mechanism.
Reproducer:
ip link add team0 type team
ethtool -K team0 lro on
for i in {1..200}
do
ip link add team$i master team0 type team
ethtool -K team$i lro on
done
ethtool -K team0 lro off
In order to fix it, the notifier_ctx member of bonding/team is introduced.

debugobjects: Don't wake up kswapd from fill_pool()
commit eb799279fb1f9c63c520fe8c1c41cb9154252db6 upstream.
syzbot is reporting a lockdep warning in fill_pool() because the allocation
from debugobjects is using GFP_ATOMIC, which is (__GFP_HIGH | __GFP_KSWAPD_RECLAIM)
and therefore tries to wake up kswapd, which acquires kswapd_wait::lock.
Since fill_pool() might be called with arbitrary locks held, fill_pool()
should not assume that acquiring kswapd_wait::lock is safe.
Use __GFP_HIGH instead and remove __GFP_NORETRY as it is pointless for
!__GFP_DIRECT_RECLAIM allocation.

x86/topology: Fix erroneous smp_num_siblings on Intel Hybrid platforms
commit edc0a2b5957652f4685ef3516f519f84807087db upstream. Traditionally, all CPUs in a system have identical numbers of SMT siblings. That changes with hybrid processors where some logical CPUs have a sibling and others have none. Today, the CPU boot code sets the global variable smp_num_siblings when every CPU thread is brought up. The last thread to boot will overwrite it with the number of siblings of *that* thread. That last thread to boot will "win". If the thread is a Pcore, smp_num_siblings == 2. If it is an Ecore, smp_num_siblings == 1. smp_num_siblings describes if the *system* supports SMT. It should specify the maximum number of SMT threads among all cores. Ensure that smp_num_siblings represents the system-wide maximum number of siblings by always increasing its value. Never allow it to decrease. On MeteorLake-P platform, this fixes a problem that the Ecore CPUs are not updated in any cpu sibling map because the system is treated as an UP system when probing Ecore CPUs. Below shows part of the CPU topology information before and after the fix, for both Pcore and Ecore CPU (cpu0 is Pcore, cpu 12 is Ecore). ... -/sys/devices/system/cpu/cpu0/topology/package_cpus:000fff -/sys/devices/system/cpu/cpu0/topology/package_cpus_list:0-11 +/sys/devices/system/cpu/cpu0/topology/package_cpus:3fffff +/sys/devices/system/cpu/cpu0/topology/package_cpus_list:0-21 ... -/sys/devices/system/cpu/cpu12/topology/package_cpus:001000 -/sys/devices/system/cpu/cpu12/topology/package_cpus_list:12 +/sys/devices/system/cpu/cpu12/topology/package_cpus:3fffff +/sys/devices/system/cpu/cpu12/topology/package_cpus_list:0-21 Notice that the "before" 'package_cpus_list' has only one CPU. This means that userspace tools like lscpu will see a little laptop like an 11-socket system: -Core(s) per socket: 1 -Socket(s): 11 +Core(s) per socket: 16 +Socket(s): 1 This is also expected to make the scheduler do rather wonky things too.

parisc: Fix flush_dcache_page() for usage from irq context
commit 61e150fb310729c98227a5edf6e4a3619edc3702 upstream. Since at least kernel 6.1, flush_dcache_page() is called with IRQs disabled, e.g. from aio_complete(). But the current implementation for flush_dcache_page() on parisc unintentionally re-enables IRQs, which may lead to deadlocks. Fix it by using xa_lock_irqsave() and xa_unlock_irqrestore() for the flush_dcache_mmap_*lock() macros instead.

selftests/memfd: Fix unknown type name build failure
Partially backport v6.3 commit 11f75a01448f ("selftests/memfd: add tests
for MFD_NOEXEC_SEAL MFD_EXEC") to fix an unknown type name build error.
In some systems, the __u64 typedef is not present due to differences in
system headers, causing compilation errors like this one:
fuse_test.c:64:8: error: unknown type name '__u64'
64 | static __u64 mfd_assert_get_seals(int fd)
This header includes the __u64 typedef which increases the likelihood
of successful compilation on a wider variety of systems.

x86/mm: Avoid incomplete Global INVLPG flushes
commit ce0b15d11ad837fbacc5356941712218e38a0a83 upstream. The INVLPG instruction is used to invalidate TLB entries for a specified virtual address. When PCIDs are enabled, INVLPG is supposed to invalidate TLB entries for the specified address for both the current PCID *and* Global entries. (Note: Only kernel mappings set Global=1.) Unfortunately, some INVLPG implementations can leave Global translations unflushed when PCIDs are enabled. As a workaround, never enable PCIDs on affected processors. I expect there to eventually be microcode mitigations to replace this software workaround. However, the exact version numbers where that will happen are not known today. Once the version numbers are set in stone, the processor list can be tweaked to only disable PCIDs on affected processors with affected microcode. Note: if anyone wants a quick fix that doesn't require patching, just stick 'nopcid' on your kernel command-line.

m68k: Move signal frame following exception on 68020/030
commit b845b574f86dcb6a70dfa698aa87a237b0878d2a upstream. On 68030/020, an instruction such as, moveml %a2-%a3/%a5,%sp@- may cause a stack page fault during instruction execution (i.e. not at an instruction boundary) and produce a format 0xB exception frame. In this situation, the value of USP will be unreliable. If a signal is to be delivered following the exception, this USP value is used to calculate the location for a signal frame. This can result in a corrupted user stack. The corruption was detected in dash (actually in glibc) where it showed up as an intermittent "stack smashing detected" message and crash following signal delivery for SIGCHLD. It was hard to reproduce that failure because delivery of the signal raced with the page fault and because the kernel places an unpredictable gap of up to 7 bytes between the USP and the signal frame. A format 0xB exception frame can be produced by a bus error or an address error. The 68030 Users Manual says that address errors occur immediately upon detection during instruction prefetch. The instruction pipeline allows prefetch to overlap with other instructions, which means an address error can arise during the execution of a different instruction. So it seems likely that this patch may help in the address error case also.

mt76: mt7615: Fix build with older compilers
commit f53300fdaa84dc02f96ab9446b5bac4d20016c43 upstream.
Some compilers (tested with 4.8.5 from CentOS 7) fail properly process
FIELD_GET inside an inline function, which ends up in a BUILD_BUG_ON.
Convert inline function to a macro.

spi: fsl-cpm: Use 16 bit mode for large transfers with even size
(cherry picked from upstream fc96ec826bced75cc6b9c07a4ac44bbf651337ab) On CPM, the RISC core is a lot more efficiant when doing transfers in 16-bits chunks than in 8-bits chunks, but unfortunately the words need to be byte swapped as seen in a previous commit. So, for large tranfers with an even size, allocate a temporary tx buffer and byte-swap data before and after transfer. This change allows setting higher speed for transfer. For instance on an MPC 8xx (CPM1 comms RISC processor), the documentation tells that transfer in byte mode at 1 kbit/s uses 0.200% of CPM load at 25 MHz while a word transfer at the same speed uses 0.032% of CPM load. This means the speed can be 6 times higher in word mode for the same CPM load. For the time being, only do it on CPM1 as there must be a trade-off between the CPM load reduction and the CPU load required to byte swap the data.

spi: fsl-spi: Re-organise transfer bits_per_word adaptation
(backported from upstream 8a5299a1278eadf1e08a598a5345c376206f171e) For different reasons, fsl-spi driver performs bits_per_word modifications for different reasons: - On CPU mode, to minimise amount of interrupts - On CPM/QE mode to work around controller byte order For CPU mode that's done in fsl_spi_prepare_message() while for CPM mode that's done in fsl_spi_setup_transfer(). Reunify all of it in fsl_spi_prepare_message(), and catch impossible cases early through master's bits_per_word_mask instead of returning EINVAL later.

watchdog: sp5100_tco: Immediately trigger upon starting.
commit 4eda19cc8a29cde3580ed73bf11dc73b4e757697 upstream. The watchdog countdown is supposed to begin when the device file is opened. Instead, it would begin countdown upon the first write to or close of the device file. Now, the ping operation is called within the start operation which ensures the countdown begins. From experimenation, it does not appear possible to do this with a single write including both the start bit and the trigger bit. So, it is done as two distinct writes.

s390/qdio: fix do_sqbs() inline assembly constraint
[ Upstream commit 2862a2fdfae875888e3c1c3634e3422e01d98147 ]
Use "a" constraint instead of "d" constraint to pass the state parameter to
the do_sqbs() inline assembly. This prevents that general purpose register
zero is used for the state parameter.
If the compiler would select general purpose register zero this would be
problematic for the used instruction in rsy format: the register used for
the state parameter is a base register. If the base register is general
purpose register zero the contents of the register are unexpectedly ignored
when the instruction is executed.
This only applies to z/VM guests using QIOASSIST with dedicated (pass through)
QDIO-based devices such as FCP [zfcp driver] as well as real OSA or
HiperSockets [qeth driver].
A possible symptom for this case using zfcp is the following repeating kernel
message pattern:
zfcp <devbusid>: A QDIO problem occurred
zfcp <devbusid>: A QDIO problem occurred
zfcp <devbusid>: qdio: ZFCP on SC <sc> using AI:1 QEBSM:1 PRI:1 TDD:1 SIGA: W
zfcp <devbusid>: A QDIO problem occurred
zfcp <devbusid>: A QDIO problem occurred
Each of the qdio problem message can be accompanied by the following entries
for the affected subchannel <sc> in
/sys/kernel/debug/s390dbf/qdio_error/hex_ascii for zfcp or qeth:
<sc> ccq: 69....
<sc> SQBS ERROR.
