bpf: Refuse unused attributes in bpf_prog_{attach,detach}

The recently added tcx attachment extended the BPF UAPI for attaching and

for tcx, other types like cgroups and flow dissector silently ignore the
new fields except for the new flags.

This is problematic once we extend bpf_mprog to older attachment types, since
it's hard to figure out whether the syscall really was successful if the
kernel silently ignores non-zero values.

While working on the ebpf-go [0] library integration for bpf_mprog and tcx,
Lorenz noticed that two subsequent BPF_PROG_QUERY requests currently fail. A
typical workflow is to first gather the bpf_mprog count without passing program/
link arrays, followed by the second request which contains the actual array
pointers.

The initial call populates count and revision fields. The second call gets
rejected due to a BPF_PROG_QUERY_LAST_FIELD bug which should point to
query.revision instead of query.link_attach_flags since the former is really
the last member.

It was not noticed in libbpf as bpf_prog_query_opts() always calls bpf(2) with
an on-stack bpf_attr that is memset() each time (and therefore query.revision
was reset to zero).

system registers. However, for write-access to be allowed by ELs lower
than EL3, the EL3 firmware needs to update the setting on the ACTLR3_EL3
register, as it is disallowed by default.

That configuration is not done on the firmware used by the MT8195 SoC,

mt8195-cherry-tomato-r2 with CONFIG_ARM_DSU_PMU enabled hangs the kernel
just as it writes to the CLUSTERPMOVSCLR_EL1 register, since the
instruction faults to EL3, and BL31 apparently just re-runs the
instruction over and over.

Mark the DSU PMU node in the Devicetree with status "fail", as the
machine doesn't have a suitable firmware to make use of it from the
kernel, and allowing its driver to probe would hang the kernel.

MAINTAINERS: Add Angelo as MediaTek SoC co-maintainer

I am a top reviewer mainly for MediaTek SoC related patches in most
subsystems and I've also been upstreaming both improvements, fixes
and new drivers and devicetrees when required.

The MediaTek scene saw a generous increase in number of patches that
are sent to the lists every week, increasing the amount of required
efforts to maintain the MTK bits overall, and we will possibly see
even more of that.

For this reason, and also because of suggestions and encouragement
coming from the community, I'm stepping up to be a co-maintainer of
MediaTek SoCs support.

Hans de Goede [Thu, 5 Oct 2023 18:26:38 +0000 (20:26 +0200)]
HID: logitech-hidpp: Fix kernel crash on receiver USB disconnect

hidpp_connect_event() has *four* time-of-check vs time-of-use (TOCTOU)
races when it races with itself.

hidpp_connect_event() primarily runs from a workqueue but it also runs
on probe() and if a "device-connected" packet is received by the hw
when the thread running hidpp_connect_event() from probe() is waiting on
the hw, then a second thread running hidpp_connect_event() will be
started from the workqueue.

This opens the following races (note the below code is simplified):

1. Retrieving + printing the protocol (harmless race):

if (!hidpp->protocol_major) {
hidpp_root_get_protocol_version()
hidpp->protocol_major = response.rap.params[0];
}

We can actually see this race hit in the dmesg in the abrt output
attached to rhbz#2227968:

[ 3064.624215] logitech-hidpp-device 0003:046D:4071.0049: HID++ 4.5 device connected.
[ 3064.658184] logitech-hidpp-device 0003:046D:4071.0049: HID++ 4.5 device connected.

Testing with extra logging added has shown that after this the 2 threads
take turn grabbing the hw access mutex (send_mutex) so they ping-pong
through all the other TOCTOU cases managing to hit all of them:

2. Updating the name to the HIDPP name (harmless race):

if (hidpp->name == hdev->name) {
...
hidpp->name = new_name;
}

3. Initializing the power_supply class for the battery (problematic!):

hidpp_initialize_battery()
{
        if (hidpp->battery.ps)
                return 0;

probe_battery(); /* Blocks, threads take turns executing this */

hidpp->battery.desc.properties =
devm_kmemdup(dev, hidpp_battery_props, cnt, GFP_KERNEL);

hidpp->battery.ps =
devm_power_supply_register(&hidpp->hid_dev->dev,
   &hidpp->battery.desc, cfg);
}

4. Creating delayed input_device (potentially problematic):

if (hidpp->delayed_input)
return;

hidpp->delayed_input = hidpp_allocate_input(hdev);

The really big problem here is 3. Hitting the race leads to the following
sequence:

hidpp->battery.desc.properties =
devm_kmemdup(dev, hidpp_battery_props, cnt, GFP_KERNEL);

hidpp->battery.ps =
devm_power_supply_register(&hidpp->hid_dev->dev,
   &hidpp->battery.desc, cfg);

...

hidpp->battery.desc.properties =
devm_kmemdup(dev, hidpp_battery_props, cnt, GFP_KERNEL);

hidpp->battery.ps =
devm_power_supply_register(&hidpp->hid_dev->dev,
   &hidpp->battery.desc, cfg);

So now we have registered 2 power supplies for the same battery,
which looks a bit weird from userspace's pov but this is not even
the really big problem.

Notice how:

1. This is all devm-maganaged
2. The hidpp->battery.desc struct is shared between the 2 power supplies
3. hidpp->battery.desc.properties points to the result from the second
   devm_kmemdup()

This causes a use after free scenario on USB disconnect of the receiver:
1. The last registered power supply class device gets unregistered
2. The memory from the last devm_kmemdup() call gets freed,
   hidpp->battery.desc.properties now points to freed memory
3. The first registered power supply class device gets unregistered,
   this involves sending a remove uevent to userspace which invokes
   power_supply_uevent() to fill the uevent data
4. power_supply_uevent() uses hidpp->battery.desc.properties which
   now points to freed memory leading to backtraces like this one:

12 months agocan: sja1000: Always restart the Tx queue after an overrun
Miquel Raynal [Mon, 2 Oct 2023 16:02:06 +0000 (18:02 +0200)]
can: sja1000: Always restart the Tx queue after an overrun

Upstream commit 717c6ec241b5 ("can: sja1000: Prevent overrun stalls with
a soft reset on Renesas SoCs") fixes an issue with Renesas own SJA1000
CAN controller reception: the Rx buffer is only 5 messages long, so when
the bus loaded (eg. a message every 50us), overrun may easily
happen. Upon an overrun situation, due to a possible internal crosstalk
situation, the controller enters a frozen state which only can be
unlocked with a soft reset (experimentally). The solution was to offload
a call to sja1000_start() in a threaded handler. This needs to happen in
process context as this operation requires to sleep. sja1000_start()
basically enters "reset mode", performs a proper software reset and
returns back into "normal mode".

Since this fix was introduced, we no longer observe any stalls in
reception. However it was sporadically observed that the transmit path
would now freeze. Further investigation blamed the fix mentioned above,
and especially the reset operation. Reproducing the reset in a loop
helped identifying what could possibly go wrong. The sja1000 is a single
Tx queue device, which leverages the netdev helpers to process one Tx
message at a time. The logic is: the queue is stopped, the message sent
to the transceiver, once properly transmitted the controller sets a
status bit which triggers an interrupt, in the interrupt handler the
transmission status is checked and the queue woken up. Unfortunately, if
an overrun happens, we might perform the soft reset precisely between
the transmission of the buffer to the transceiver and the advent of the
transmission status bit. We would then stop the transmission operation
without re-enabling the queue, leading to all further transmissions to
be ignored.

The reset interrupt can only happen while the device is "open", and
after a reset we anyway want to resume normal operations, no matter if a
packet to transmit got dropped in the process, so we shall wake up the
queue. Restarting the device and waking-up the queue is exactly what
sja1000_set_mode(CAN_MODE_START) does. In order to be consistent about
the queue state, we must acquire a lock both in the reset handler and in
the transmit path to ensure serialization of both operations. It turns
out, a lock is already held when entering the transmit path, so we can
just acquire/release it as well with the regular net helpers inside the
threaded interrupt handler and this way we should be safe. As the
reset handler might still be called after the transmission of a frame to
the transceiver but before it actually gets transmitted, we must ensure
we don't leak the skb, so we free it (the behavior is consistent, no
matter if there was an skb on the stack or not).

12 months agonet: sched: cls_u32: Fix allocation size in u32_init()
Gustavo A. R. Silva [Wed, 4 Oct 2023 13:19:37 +0000 (15:19 +0200)]
net: sched: cls_u32: Fix allocation size in u32_init()

commit d61491a51f7e ("net/sched: cls_u32: Replace one-element array
with flexible-array member") incorrecly replaced an instance of
`sizeof(*tp_c)` with `struct_size(tp_c, hlist->ht, 1)`. This results
in a an over-allocation of 8 bytes.

This change is wrong because `hlist` in `struct tc_u_common` is a
pointer:

net/sched/cls_u32.c:
struct tc_u_common {
        struct tc_u_hnode __rcu *hlist;
        void                    *ptr;
        int                     refcnt;
        struct idr              handle_idr;
        struct hlist_node       hnode;
        long                    knodes;
};

So, the use of `struct_size()` makes no sense: we don't need to allocate
any extra space for a flexible-array member. `sizeof(*tp_c)` is just fine.

So, `struct_size(tp_c, hlist->ht, 1)` translates to:

sizeof(*tp_c) + sizeof(tp_c->hlist->ht) ==
sizeof(struct tc_u_common) + sizeof(struct tc_u_knode *) ==
144 + 8  == 0x98 (byes)
     ^^^
      |
unnecessary extra
allocation size

$ pahole -C tc_u_common net/sched/cls_u32.o
struct tc_u_common {
struct tc_u_hnode *        hlist;                /*     0     8 */
void *                     ptr;                  /*     8     8 */
int                        refcnt;               /*    16     4 */

/* XXX 4 bytes hole, try to pack */

struct idr                 handle_idr;           /*    24    96 */
/* --- cacheline 1 boundary (64 bytes) was 56 bytes ago --- */
struct hlist_node          hnode;                /*   120    16 */
/* --- cacheline 2 boundary (128 bytes) was 8 bytes ago --- */
long int                   knodes;               /*   136     8 */

/* size: 144, cachelines: 3, members: 6 */
/* sum members: 140, holes: 1, sum holes: 4 */
/* last cacheline: 16 bytes */
};

And with `sizeof(*tp_c)`, we have:

sizeof(*tp_c) == sizeof(struct tc_u_common) == 144 == 0x90 (bytes)

which is the correct and original allocation size.

Fix this issue by replacing `struct_size(tp_c, hlist->ht, 1)` with
`sizeof(*tp_c)`, and avoid allocating 8 too many bytes.

The following difference in binary output is expected and reflects the
desired change:

Besides the QCA8337 switch the Turris 1.x device has on it's MDIO bus
also Micron ethernet PHY (dedicated to the WAN port).

We've been experiencing a strange behavior of the WAN ethernet
interface, wherein the WAN PHY started timing out the MDIO accesses, for
example when the interface was brought down and then back up.

Bisecting led to commit 2cd548566384 ("net: dsa: qca8k: add support for
phy read/write with mgmt Ethernet"), which added support to access the
QCA8337 switch's internal PHYs via management ethernet frames.

Connecting the MDIO bus pins onto an oscilloscope, I was able to see
that the MDIO bus was active whenever a request to read/write an
internal PHY register was done via an management ethernet frame.

My theory is that when the switch core always communicates with the
internal PHYs via the MDIO bus, even when externally we request the
access via ethernet. This MDIO bus is the same one via which the switch
and internal PHYs are accessible to the board, and the board may have
other devices connected on this bus. An ASCII illustration may give more
insight:

   |                  |  o--|  ...  | |
   +----------------------------------+

When we send a request to read an internal PHY register via an ethernet
management frame via eth1, the switch core receives the ethernet frame
on port 0 and then communicates with the internal PHY via MDIO. At this
time, other potential devices, such as the WAN PHY on Turris 1.x, cannot
use the MDIO bus, since it may cause a bus conflict.

Fix this issue by locking the MDIO bus even when we are accessing the
PHY registers via ethernet management frames.

net: dsa: qca8k: fix regmap bulk read/write methods on big endian systems

Commit c766e077d927 ("net: dsa: qca8k: convert to regmap read/write
API") introduced bulk read/write methods to qca8k's regmap.

The regmap bulk read/write methods get the register address in a buffer
passed as a void pointer parameter (the same buffer contains also the
read/written values). The register address occupies only as many bytes
as it requires at the beginning of this buffer. For example if the
.reg_bits member in regmap_config is 16 (as is the case for this
driver), the register address occupies only the first 2 bytes in this
buffer, so it can be cast to u16.

But the original commit implementing these bulk read/write methods cast
the buffer to u32:
  u32 reg = *(u32 *)reg_buf & U16_MAX;
taking the first 4 bytes. This works on little endian systems where the
first 2 bytes of the buffer correspond to the low 16-bits, but it
obviously cannot work on big endian systems.

Fix this by casting the beginning of the buffer to u16 as
   u32 reg = *(u16 *)reg_buf;

Eric has reported that commit dabc8b207566 ("quota: fix dqput() to
follow the guarantees dquot_srcu should provide") heavily increases
runtime of generic/270 xfstest for ext4 in nojournal mode. The reason
for this is that ext4 in nojournal mode leaves dquots dirty until the last
dqput() and thus the cleanup done in quota_release_workfn() has to write
them all. Due to the way quota_release_workfn() is written this results
in synchronize_srcu() call for each dirty dquot which makes the dquot
cleanup when turning quotas off extremely slow.

To be able to avoid synchronize_srcu() for each dirty dquot we need to
rework how we track dquots to be cleaned up. Instead of keeping the last
dquot reference while it is on releasing_dquots list, we drop it right
away and mark the dquot with new DQ_RELEASING_B bit instead. This way we
can we can remove dquot from releasing_dquots list when new reference to
it is acquired and thus there's no need to call synchronize_srcu() each
time we drop dq_list_lock.

HID: i2c-hid: fix handling of unpopulated devices

A recent commit reordered probe so that the interrupt line is now
requested before making sure that the device exists.

This breaks machines like the Lenovo ThinkPad X13s which rely on the
HID driver to probe second-source devices and only register the variant
that is actually populated. Specifically, the interrupt line may now
already be (temporarily) claimed when doing asynchronous probing of the
touchpad:

genirq: Flags mismatch irq 191. 00082008 (hid-over-i2c) vs. 00082008 (hid-over-i2c)
i2c_hid_of 21-0015: Could not register for hid-over-i2c interrupt, irq = 191, ret = -16
i2c_hid_of: probe of 21-0015 failed with error -16

Fix this by restoring the old behaviour of first making sure the device
exists before requesting the interrupt line.

Note that something like this should probably be implemented also for
"panel followers", whose actual probe is currently effectively deferred
until the DRM panel is probed (e.g. by powering down the device after
making sure it exists and only then register it as a follower).

Xuewen Yan [Wed, 19 Jul 2023 13:05:27 +0000 (21:05 +0800)]
cpufreq: schedutil: Update next_freq when cpufreq_limits change

When cpufreq's policy is 'single', there is a scenario that will
cause sg_policy's next_freq to be unable to update.

When the CPU's util is always max, the cpufreq will be max,
and then if we change the policy's scaling_max_freq to be a
lower freq, indeed, the sg_policy's next_freq need change to
be the lower freq, however, because the cpu_is_busy, the next_freq
would keep the max_freq.

For example:

The cpu7 is a single CPU:

  unisoc:/sys/devices/system/cpu/cpufreq/policy7 # while true;do done& [1] 4737
  unisoc:/sys/devices/system/cpu/cpufreq/policy7 # taskset -p 80 4737
  pid 4737's current affinity mask: ff
  pid 4737's new affinity mask: 80
  unisoc:/sys/devices/system/cpu/cpufreq/policy7 # cat scaling_max_freq
  2301000
  unisoc:/sys/devices/system/cpu/cpufreq/policy7 # cat scaling_cur_freq
  2301000
  unisoc:/sys/devices/system/cpu/cpufreq/policy7 # echo 2171000 > scaling_max_freq
  unisoc:/sys/devices/system/cpu/cpufreq/policy7 # cat scaling_max_freq
  2171000

At this time, the sg_policy's next_freq would stay at 2301000, which
is wrong.

To fix this, add a check for the ->need_freq_update flag.

creating additional subflows with the local addr ID 0.

There is no reason not to allow additional subflows from this local
address: we should be able to create new subflows from the initial
endpoint. This limitation was breaking fullmesh support from userspace.

12 months agomptcp: fix delegated action races
Paolo Abeni [Wed, 4 Oct 2023 20:38:11 +0000 (13:38 -0700)]
mptcp: fix delegated action races

The delegated action infrastructure is prone to the following
race: different CPUs can try to schedule different delegated
actions on the same subflow at the same time.

Each of them will check different bits via mptcp_subflow_delegate(),
and will try to schedule the action on the related per-cpu napi
instance.

Depending on the timing, both can observe an empty delegated list
node, causing the same entry to be added simultaneously on two different
lists.

The root cause is that the delegated actions infra does not provide
a single synchronization point. Address the issue reserving an additional
bit to mark the subflow as scheduled for delegation. Acquiring such bit
guarantee the caller to own the delegated list node, and being able to
safely schedule the subflow.

Clear such bit only when the subflow scheduling is completed, ensuring
proper barrier in place.

Additionally swap the meaning of the delegated_action bitmask, to allow
the usage of the existing helper to set multiple bit at once.

the log looks like:

    mmc0: Unable to allocate ADMA buffers - falling back to standard DMA

The logic is: generic riscv defconfig selects ARCH_RENESAS then
ARCH_R9A07G043 which selects DMA_GLOBAL_POOL, which assumes all
non-dma-coherent riscv platforms have a dma global pool, this assumption
seems not correct. And I believe DMA_GLOBAL_POOL should not be
selected by ARCH_SOCFAMILIY, instead, only ARCH under some specific
conditions can select it globaly, for example NOMMU ARM and so on,
because it's designed for special cases such as "nommu cases where
non-cacheable memory lives in a fixed place in the physical address
map" as pointed out by Robin.

Fix the issue by making ARCH_R9A07G043 (riscv version) depend on
NONPORTABLE, thus generic defconfig won't select ARCH_R9A07G043 by

drm/amd/display: apply edge-case DISPCLK WDIVIDER changes to master OTG pipes only

[Why]
The edge-case DISPCLK WDIVIDER changes call stream_enc functions.
But with MPC pipes, downstream pipes have null stream_enc and will
 cause crash.

[How]
Only call stream_enc functions for pipes that are OTG master.

12 months agodrm/amd: Fix detection of _PR3 on the PCIe root port

drm/amd: Fix detection of _PR3 on the PCIe root port

On some systems with Navi3x dGPU will attempt to use BACO for runtime
PM but fails to resume properly.  This is because on these systems
the root port goes into D3cold which is incompatible with BACO.

This happens because in this case dGPU is connected to a bridge between
root port which causes BOCO detection logic to fail.  Fix the intent of
the logic by looking at root port, not the immediate upstream bridge for
_PR3.
