KVM: x86: hyper-v: replace bitmap_weight() with hweight64()

kvm_hv_flush_tlb() applies bitmap API to a u64 variable valid_bank_mask.
Since valid_bank_mask has a fixed size, we can use hweight64() and avoid
excessive bloating.

KVM: x86: hyper-v: fix type of valid_bank_mask

In kvm_hv_flush_tlb(), valid_bank_mask is declared as unsigned long,
but is used as u64, which is wrong for i386, and has been spotted by
LKP after applying "KVM: x86: hyper-v: replace bitmap_weight() with
hweight64()"

https://lore.kernel.org/lkml/20220510154750.212913-12-yury.norov@gmail.com/

But it's wrong even without that patch because now bitmap_weight()
dereferences a word after valid_bank_mask on i386.

Manipulating 64-bit arrays with bitmap functions is potentially dangerous

On LE systems bitmaps are naturally ordered, therefore we can potentially

system is 64-bit. But it may lead to out-of-bond access due to unsafe
typecast, and the bitmap_(from,to)_arr32 comment doesn't explain that

MAINTAINERS: add cpumask and nodemask files to BITMAP_API

cpumask and nodemask APIs are thin wrappers around basic bitmap API, and

arch/x86: replace nodes_weight with nodes_empty where appropriate

mm code calls nodes_weight() to check if any bit of a given nodemask is

parisc: fix a crash with multicore scheduler

With the kernel 5.18, the system will hang on boot if it is compiled with
CONFIG_SCHED_MC. The last printed message is "Brought up 1 node, 1 CPU".

The crash happens in sd_init
tl->mask (which is cpu_coregroup_mask) returns an empty mask. This happens
because cpu_topology[0].core_sibling is empty.
Consequently, sd_span is set to an empty mask
sd_id = cpumask_first(sd_span) sets sd_id == NR_CPUS (because the mask is
empty)
sd->shared = *per_cpu_ptr(sdd->sds, sd_id); sets sd->shared to NULL
because sd_id is out of range
atomic_inc(&sd->shared->ref); crashes without printing anything

We can fix it by calling reset_cpu_topology() from init_cpu_topology() -
this will initialize the sibling masks on CPUs, so that they're not empty.

This patch also removes the variable "dualcores_found", it is useless,
because during boot, init_cpu_topology is called before
store_cpu_topology. Thus, set_sched_topology(parisc_mc_topology) is never
called. We don't need to call it at all because default_topology in
kernel/sched/topology.c contains the same items as parisc_mc_topology.

Note that we should not call store_cpu_topology() from init_per_cpu()
because it is called too early in the kernel initialization process and it
results in the message "Failure to register CPU0 device". Before this
patch, store_cpu_topology() would exit immediatelly because
cpuid_topo->core id was uninitialized and it was 0.

block: Fix potential deadlock in blk_ia_range_sysfs_show()

When being read, a sysfs attribute is already protected against removal
with the kobject node active reference counter. As a result, in
blk_ia_range_sysfs_show(), there is no need to take the queue sysfs
lock when reading the value of a range attribute. Using the queue sysfs
lock in this function creates a potential deadlock situation with the
disk removal, something that a lockdep signals with a splat when the
device is removed:

[  760.703551]  Possible unsafe locking scenario:
[  760.703551]
[  760.703554]        CPU0                    CPU1

[  760.703558]   lock(&q->sysfs_lock);
[  760.703565]                                lock(kn->active#385);

Solve this by removing the mutex_lock()/mutex_unlock() calls from
blk_ia_range_sysfs_show().

riscv: Move alternative length validation into subsection

          ^

This error happens because LLVM's integrated assembler has a one-pass
design, which means it cannot figure out the instruction lengths when
the .org directive is outside of the subsection that contains the
instructions, which was changed by the .option directives added by the
above change.

Move the .org directives before the .previous directive so that these
directives are always within the same subsection, which resolves the
failures and does not introduce any new issues with GNU as. This was
done for arm64 in commit 966a0acce2fc ("arm64/alternatives: move length
validation inside the subsection") and commit 22315a2296f4 ("arm64:
alternatives: Move length validation in alternative_{insn, endif}").

While there is no error from the assembly versions of the macro, they
appear to have the same problem so just make the same change there as
well so that there are no problems in the future.

module: Fix prefix for module.sig_enforce module param

Commit cfc1d277891e ("module: Move all into module/") changed the prefix
of the module param by moving/renaming files. A later commit also moves
the module_param() into a different file, thereby changing the prefix
yet again.

This would break kernel cmdline compatibility and also userspace
compatibility at /sys/module/module/parameters/sig_enforce.

So, set the prefix back to "module.".

arm64: Initialize jump labels before setup_machine_fdt()

A static key warning splat appears during early boot on arm64 systems
that credit randomness from devicetrees that contain an "rng-seed"
property. This is because setup_machine_fdt() is called before
jump_label_init() during setup_arch(). Let's swap the order of these two
calls so that jump labels are initialized before the devicetree is
unflattened and the rng seed is credited.

x86/sgx: Set active memcg prior to shmem allocation

When the system runs out of enclave memory, SGX can reclaim EPC pages
by swapping to normal RAM. These backing pages are allocated via a
per-enclave shared memory area. Since SGX allows unlimited over
commit on EPC memory, the reclaimer thread can allocate a large
number of backing RAM pages in response to EPC memory pressure.

When the shared memory backing RAM allocation occurs during
the reclaimer thread context, the shared memory is charged to
the root memory control group, and the shmem usage of the enclave
is not properly accounted for, making cgroups ineffective at
limiting the amount of RAM an enclave can consume.

For example, when using a cgroup to launch a set of test
enclaves, the kernel does not properly account for 50% - 75% of
shmem page allocations on average. In the worst case, when
nearly all allocations occur during the reclaimer thread, the
kernel accounts less than a percent of the amount of shmem used
by the enclave's cgroup to the correct cgroup.

SGX stores a list of mm_structs that are associated with
an enclave. Pick one of them during reclaim and charge that
mm's memcg with the shmem allocation. The one that gets picked
is arbitrary, but this list almost always only has one mm. The
cases where there is more than one mm with different memcg's
are not worth considering.

Create a new function - sgx_encl_alloc_backing(). This function
is used whenever a new backing storage page needs to be
allocated. Previously the same function was used for page
allocation as well as retrieving a previously allocated page.
Prior to backing page allocation, if there is a mm_struct associated
with the enclave that is requesting the allocation, it is set
as the active memory control group.

Eric Dumazet says:

====================
net: af_packet: be careful when expanding mac header size

A recent regression in af_packet needed a preliminary debug patch,
which will presumably be useful for next bugs hunting.

The af_packet fix is to make sure MAC headers are contained in
skb linear part, as GSO stack requests.

v2: CONFIG_DEBUG_NET depends on CONFIG_NET to avoid compile
errors found by kernel bots.

net/af_packet: make sure to pull mac header

GSO assumes skb->head contains link layer headers.

tun device in some case can provide base 14 bytes,
regardless of VLAN being used or not.

After blamed commit, we can end up setting a network
header offset of 18+, we better pull the missing
bytes to avoid a posible crash in GSO.

net: stmmac: use dev_err_probe() for reporting mdio bus registration failure

I have a board where these two lines are always printed during boot:

imx-dwmac 30bf0000.ethernet: Cannot register the MDIO bus
imx-dwmac 30bf0000.ethernet: stmmac_dvr_probe: MDIO bus (id: 1) registration failed

It's perfectly fine, and the device is successfully (and silently, as
far as the console goes) probed later.

Use dev_err_probe() instead, which will demote these messages to debug
level (thus removing the alarming messages from the console) when the
error is -EPROBE_DEFER, and also has the advantage of including the
error code if/when it happens to be something other than -EPROBE_DEFER.

While here, add the missing \n to one of the format strings.

binder: fix sender_euid type in uapi header

The {pid,uid}_t fields of struct binder_transaction were recently
replaced to use kernel types in commit 169adc2b6b3c ("android/binder.h:
add linux/android/binder(fs).h to UAPI compile-test coverage").

However, using __kernel_uid_t here breaks backwards compatibility in
architectures using 16-bits for this type, since glibc and some others
still expect a 32-bit uid_t. Instead, let's use __kernel_uid32_t which
avoids this compatibility problem.

block: null_blk: Fix null_zone_write()

The bio and rq fields of struct nullb_cmd are now overlapping in a
union. So we cannot use a test on ->bio being non-NULL to detect the
NULL_Q_BIO queue mode. null_zone_write() use such broken test to set the
sector position of a zone append write in the command bio or request.
When the null_blk device uses the NULL_Q_MQ queue mode,
null_zone_write() wrongly end up setting the bio sector position,
resulting in the command request to be broken and random crashes
following.

Fix this by testing the device queue mode directly.

ice: fix access-beyond-end in the switch code

Global `-Warray-bounds` enablement revealed some problems, one of
which is the way we define and use AQC rules messages.
In fact, they have a shared header, followed by the actual message,
which can be of one of several different formats. So it is
straightforward enough to define that header as a separate struct
and then embed it into message structures as needed, but currently
all the formats reside in one union coupled with the header. Then,
the code allocates only the memory needed for a particular message
format, leaving the union potentially incomplete.
There are no actual reads or writes beyond the end of an allocated
chunk, but at the same time, the whole implementation is fragile and
backed by an equilibrium rather than strong type and memory checks.

Define the structures the other way around: one for the common
header and the rest for the actual formats with the header embedded.
There are no places where several union members would be used at the
same time anyway. This allows to use proper struct_size() and let
the compiler know what is going to be done.
Finally, unsilence `-Warray-bounds` back for ice_switch.c.

Other little things worth mentioning:
* &ice_sw_rule_vsi_list_query is not used anywhere, remove it. It's
  weird anyway to talk to hardware with purely kernel types
  (bitmaps);
* expand the ICE_SW_RULE_*_SIZE() macros to pass a structure
  variable name to struct_size() to let it do strict typechecking;
* rename ice_sw_rule_lkup_rx_tx::hdr to ::hdr_data to keep ::hdr
  for the header structure to have the same name for it constistenly
  everywhere;
* drop the duplicate of %ICE_SW_RULE_RX_TX_NO_HDR_SIZE residing in
  ice_switch.h.

nfp: remove padding in nfp_nfdk_tx_desc

NFDK firmware supports 48-bit dma addressing and
parses 16 high bits of dma addresses.

In nfp_nfdk_tx_desc, dma related structure and tso
related structure are union. When "mss" be filled
with nonzero value due to enable tso, the memory used
by "padding" may be also filled. Then, firmware may
parse wrong dma addresses which causes TX watchdog
timeout problem.

This patch removes padding and unifies the dma_addr_hi
bits with the one in firmware. nfp_nfdk_tx_desc_set_dma_addr
is also added to match this change.

ax25: Fix ax25 session cleanup problems

There are session cleanup problems in ax25_release() and
ax25_disconnect(). If we setup a session and then disconnect,
the disconnected session is still in "LISTENING" state that
is shown below.

Active AX.25 sockets
Dest       Source     Device  State        Vr/Vs    Send-Q  Recv-Q
DL9SAU-4   DL9SAU-3   ???     LISTENING    000/000  0       0
DL9SAU-3   DL9SAU-4   ???     LISTENING    000/000  0       0

The first reason is caused by del_timer_sync() in ax25_release().
The timers of ax25 are used for correct session cleanup. If we use
ax25_release() to close ax25 sessions and ax25_dev is not null,
the del_timer_sync() functions in ax25_release() will execute.
As a result, the sessions could not be cleaned up correctly,
because the timers have stopped.

In order to solve this problem, this patch adds a device_up flag
in ax25_dev in order to judge whether the device is up. If there
are sessions to be cleaned up, the del_timer_sync() in
ax25_release() will not execute. What's more, we add ax25_cb_del()
in ax25_kill_by_device(), because the timers have been stopped
and there are no functions that could delete ax25_cb if we do not
call ax25_release(). Finally, we reorder the position of
ax25_list_lock in ax25_cb_del() in order to synchronize among
different functions that call ax25_cb_del().

The second reason is caused by improper check in ax25_disconnect().
The incoming ax25 sessions which ax25->sk is null will close
heartbeat timer, because the check "if(!ax25->sk || ..)" is
satisfied. As a result, the session could not be cleaned up properly.

In order to solve this problem, this patch changes the improper
check to "if(ax25->sk && ..)" in ax25_disconnect().

What`s more, the ax25_disconnect() may be called twice, which is
not necessary. For example, ax25_kill_by_device() calls
ax25_disconnect() and sets ax25->state to AX25_STATE_0, but
ax25_release() calls ax25_disconnect() again.

In order to solve this problem, this patch add a check in
ax25_release(). If the flag of ax25->sk equals to SOCK_DEAD,
the ax25_disconnect() in ax25_release() should not be executed.

block: fix bio_clone_blkg_association() to associate with proper blkcg_gq

Commit d92c370a16cb ("block: really clone the block cgroup in
bio_clone_blkg_association") changed bio_clone_blkg_association() to
just clone bio->bi_blkg reference from source to destination bio. This
is however wrong if the source and destination bios are against
different block devices because struct blkcg_gq is different for each
bdev-blkcg pair. This will result in IOs being accounted (and throttled
as a result) multiple times against the same device (src bdev) while
throttling of the other device (dst bdev) is ignored. In case of BFQ the
inconsistency can even result in crashes in bfq_bic_update_cgroup().
Fix the problem by looking up correct blkcg_gq for the cloned bio.
