0b1e77f743 smp: Add missing destroy_work_on_stack() call in smp_call_on_cpu()
[ Upstream commit 77aeb1b685f9db73d276bad4bb30d48505a6fd23 ]

For CONFIG_DEBUG_OBJECTS_WORK=y kernels sscs.work defined by
INIT_WORK_ONSTACK() is initialized by debug_object_init_on_stack() for
the debug check in __init_work() to work correctly.

But this lacks the counterpart to remove the tracked object from debug
objects again, which will cause a debug object warning once the stack is
freed.

Add the missing destroy_work_on_stack() invocation to cure that.

1129f7beb1 wifi: mwifiex: Do not return unused priv in mwifiex_get_priv_by_id()
[ Upstream commit c145eea2f75ff7949392aebecf7ef0a81c1f6c14 ]

mwifiex_get_priv_by_id() returns the priv pointer corresponding to
the bss_num and bss_type, but without checking if the priv is actually
currently in use.
Unused priv pointers do not have a wiphy attached to them which can
lead to NULL pointer dereferences further down the callstack.  Fix
this by returning only used priv pointers which have priv->bss_mode
set to something else than NL80211_IFTYPE_UNSPECIFIED.

Said NULL pointer dereference happened when an Accesspoint was started
with wpa_supplicant -i mlan0 with this config:

network={
        ssid="somessid"
        mode=2
        frequency=2412
        key_mgmt=WPA-PSK WPA-PSK-SHA256
        proto=RSN
        group=CCMP
        pairwise=CCMP
        psk="12345678"
}

When waiting for the AP to be established, interrupting wpa_supplicant
with <ctrl-c> and starting it again this happens:

532ee6e841 libbpf: Add NULL checks to bpf_object__{prev_map,next_map}
[ Upstream commit cedc12c5b57f7efa6dbebfb2b140e8675f5a2616 ]

In the current state, an erroneous call to
bpf_object__find_map_by_name(NULL, ...) leads to a segmentation
fault through the following call chain:

  bpf_object__find_map_by_name(obj = NULL, ...)
  -> bpf_object__for_each_map(pos, obj = NULL)
  -> bpf_object__next_map((obj = NULL), NULL)
  -> return (obj = NULL)->maps

While calling bpf_object__find_map_by_name with obj = NULL is
obviously incorrect, this should not lead to a segmentation
fault but rather be handled gracefully.

As __bpf_map__iter already handles this situation correctly, we
can delegate the check for the regular case there and only add
a check in case the prev or next parameter is NULL.

967ec9a044 pci/hotplug/pnv_php: Fix hotplug driver crash on Powernv
[ Upstream commit 335e35b748527f0c06ded9eebb65387f60647fda ]

The hotplug driver for powerpc (pci/hotplug/pnv_php.c) causes a kernel
crash when we try to hot-unplug/disable the PCIe switch/bridge from
the PHB.

The crash occurs because although the MSI data structure has been
released during disable/hot-unplug path and it has been assigned
with NULL, still during unregistration the code was again trying to
explicitly disable the MSI which causes the NULL pointer dereference and
kernel crash.

The patch fixes the check during unregistration path to prevent invoking
pci_disable_msi/msix() since its data structure is already freed.

630897cdcb cgroup: Protect css->cgroup write under css_set_lock
[ Upstream commit 57b56d16800e8961278ecff0dc755d46c4575092 ]

The writing of css->cgroup associated with the cgroup root in
rebind_subsystems() is currently protected only by cgroup_mutex.
However, the reading of css->cgroup in both proc_cpuset_show() and
proc_cgroup_show() is protected just by css_set_lock. That makes the
readers susceptible to racing problems like data tearing or caching.
It is also a problem that can be reported by KCSAN.

This can be fixed by using READ_ONCE() and WRITE_ONCE() to access
css->cgroup. Alternatively, the writing of css->cgroup can be moved
under css_set_lock as well which is done by this patch.

1780b7b977 iommu/vt-d: Handle volatile descriptor status read
[ Upstream commit b5e86a95541cea737394a1da967df4cd4d8f7182 ]

Queued invalidation wait descriptor status is volatile in that IOMMU
hardware writes the data upon completion.

Use READ_ONCE() to prevent compiler optimizations which ensures memory
reads every time. As a side effect, READ_ONCE() also enforces strict
types and may add an extra instruction. But it should not have negative
performance impact since we use cpu_relax anyway and the extra time(by
adding an instruction) may allow IOMMU HW request cacheline ownership
easier.

e.g. gcc 12.3
BEFORE:
	81 38 ad de 00 00       cmpl   $0x2,(%rax)

AFTER (with READ_ONCE())
    772f:       8b 00                   mov    (%rax),%eax
    7731:       3d ad de 00 00          cmp    $0x2,%eax
                                        //status data is 32 bit

the dev_t format splits the minor number between the lowest 8 bytes and
highest 12 bytes. If the minor number is larger than 255, part of it

Fix this by checking that the minor number is valid and then encoding it

ea412b366f net: bridge: br_fdb_external_learn_add(): always set EXT_LEARN
[ Upstream commit bee2ef946d3184e99077be526567d791c473036f ]

When userspace wants to take over a fdb entry by setting it as
EXTERN_LEARNED, we set both flags BR_FDB_ADDED_BY_EXT_LEARN and
BR_FDB_ADDED_BY_USER in br_fdb_external_learn_add().

If the bridge updates the entry later because its port changed, we clear
the BR_FDB_ADDED_BY_EXT_LEARN flag, but leave the BR_FDB_ADDED_BY_USER
flag set.

If userspace then wants to take over the entry again,
br_fdb_external_learn_add() sees that BR_FDB_ADDED_BY_USER and skips
setting the BR_FDB_ADDED_BY_EXT_LEARN flags, thus silently ignores the
update.

Fix this by always allowing to set BR_FDB_ADDED_BY_EXT_LEARN regardless
if this was a user fdb entry or not.

40621108c5 fou: Fix null-ptr-deref in GRO.
[ Upstream commit 7e4196935069947d8b70b09c1660b67b067e75cb ]

We observed a null-ptr-deref in fou_gro_receive() while shutting down
a host.  [0]

The NULL pointer is sk->sk_user_data, and the offset 8 is of protocol
in struct fou.

When fou_release() is called due to netns dismantle or explicit tunnel
teardown, udp_tunnel_sock_release() sets NULL to sk->sk_user_data.
Then, the tunnel socket is destroyed after a single RCU grace period.

So, in-flight udp4_gro_receive() could find the socket and execute the
FOU GRO handler, where sk->sk_user_data could be NULL.

Let's use rcu_dereference_sk_user_data() in fou_from_sock() and add NULL
checks in FOU GRO handlers.

dd010dbcce usbnet: modern method to get random MAC
[ Upstream commit bab8eb0dd4cb995caa4a0529d5655531c2ec5e8e ]

The driver generates a random MAC once on load
and uses it over and over, including on two devices
needing a random MAC at the same time.

Jakub suggested revamping the driver to the modern
API for setting a random MAC rather than fixing
the old stuff.

The bug is as old as the driver.

3434278976 tcp_bpf: fix return value of tcp_bpf_sendmsg()
[ Upstream commit fe1910f9337bd46a9343967b547ccab26b4b2c6e ]

When we cork messages in psock->cork, the last message triggers the
flushing will result in sending a sk_msg larger than the current
message size. In this case, in tcp_bpf_send_verdict(), 'copied' becomes
negative at least in the following case:

468         case __SK_DROP:
469         default:
470                 sk_msg_free_partial(sk, msg, tosend);
471                 sk_msg_apply_bytes(psock, tosend);
472                 *copied -= (tosend + delta); // <==== HERE
473                 return -EACCES;

Therefore, it could lead to the following BUG with a proper value of
'copied' (thanks to syzbot). We should not use negative 'copied' as a
return value here.

725cd25fc7 platform/x86: dell-smbios: Fix error path in dell_smbios_init()
[ Upstream commit ffc17e1479e8e9459b7afa80e5d9d40d0dd78abb ]

In case of error in build_tokens_sysfs(), all the memory that has been
allocated is freed at end of this function. But then free_group() is
called which performs memory deallocation again.

Also, instead of free_group() call, there should be exit_dell_smbios_smm()
and exit_dell_smbios_wmi() calls, since there is initialization, but there
is no release of resources in case of an error.

Fix these issues by replacing free_group() call with
exit_dell_smbios_wmi() and exit_dell_smbios_smm().

[ Upstream commit ba8cf80724dbc09825b52498e4efacb563935408 ]

82580 NICs have a hardware bug that makes it
necessary to write into the TSICR (TimeSync Interrupt Cause) register
to clear it:
https://lore.kernel.org/all/CDCB8BE0.1EC2C%25matthew.vick@intel.com/

Add a conditional so only for 82580 we write into the TSICR register,
so we don't risk losing events for other models.

Without this change, when running ptp4l with an Intel 82580 card,
I get the following output:

> timed out while polling for tx timestamp increasing tx_timestamp_timeout or
> increasing kworker priority may correct this issue, but a driver bug likely
> causes it

This goes away with this change.

This (partially) reverts commit ee14cc9ea19b ("igb: Fix missing time sync events").

333529d2d4 can: bcm: Remove proc entry when dev is unregistered.
[ Upstream commit 76fe372ccb81b0c89b6cd2fec26e2f38c958be85 ]

syzkaller reported a warning in bcm_connect() below. [0]

The repro calls connect() to vxcan1, removes vxcan1, and calls
connect() with ifindex == 0.

Calling connect() for a BCM socket allocates a proc entry.
Then, bcm_sk(sk)->bound is set to 1 to prevent further connect().

However, removing the bound device resets bcm_sk(sk)->bound to 0
in bcm_notify().

The 2nd connect() tries to allocate a proc entry with the same
name and sets NULL to bcm_sk(sk)->bcm_proc_read, leaking the
original proc entry.

Since the proc entry is available only for connect()ed sockets,
let's clean up the entry when the bound netdev is unregistered.

[ Upstream commit 86f271f22bbb6391410a07e08d6ca3757fda01fa ]

Errata #i2037 in AM65x/DRA80xM Processors Silicon Revision 1.0
(SPRZ452D_July 2018_Revised December 2019 [1]) mentions when an
inbound PCIe TLP spans more than two internal AXI 128-byte bursts,
the bus may corrupt the packet payload and the corrupt data may
cause associated applications or the processor to hang.

The workaround for Errata #i2037 is to limit the maximum read
request size and maximum payload size to 128 bytes. Add workaround
for Errata #i2037 here.

The errata and workaround is applicable only to AM65x SR 1.0 and
later versions of the silicon will have this fixed.

When setting the EDID it would attempt to update two controls

If there isn't any (e.g. when the vivid module is loaded with
node_types=1), then calling VIDIOC_S_EDID would crash.

dc059c8bc2 smack: unix sockets: fix accept()ed socket label
[ Upstream commit e86cac0acdb1a74f608bacefe702f2034133a047 ]

When a process accept()s connection from a unix socket
(either stream or seqpacket)
it gets the socket with the label of the connecting process.

For example, if a connecting process has a label 'foo',
the accept()ed socket will also have 'in' and 'out' labels 'foo',
regardless of the label of the listener process.

This is because kernel creates unix child sockets
in the context of the connecting process.

I do not see any obvious way for the listener to abuse
alien labels coming with the new socket, but,
to be on the safe side, it's better fix new socket labels.

We are running nfsd servers inside of containers with their own network
namespace, and we want to monitor these services using the stats found
in /proc.  However these are not exposed in the proc inside of the
container, so we have to bind mount the host /proc into our containers
to get at this information.

Separate out the stat counters init and the proc registration, and move
the proc registration into the pernet operations entry and exit points
so that these stats can be exposed inside of network namespaces.

This is an intermediate step, this just exposes the global counters in
the network namespace.  Subsequent patches will move these counters into
the per-network namespace container.

4004e4dc9d nfsd: rename NFSD_NET_* to NFSD_STATS_*
[ Upstream commit d98416cc2154053950610bb6880911e3dcbdf8c5 ]

We're going to merge the stats all into per network namespace in
subsequent patches, rename these nn counters to be consistent with the
rest of the stats.
