When user provides a bogus pat_index value through the madvise IOCTL, the
xe_pat_index_get_coh_mode() function performs an array access without
validating bounds. This allows a malicious user to trigger an out-of-bounds
kernel read from the xe->pat.table array.
The vulnerability exists because the validation in madvise_args_are_sane()
directly calls xe_pat_index_get_coh_mode(xe, args->pat_index.val) without
first checking if pat_index is within [0, xe->pat.n_entries).
Although xe_pat_index_get_coh_mode() has a WARN_ON to catch this in debug
builds, it still performs the unsafe array access in production kernels.

Fix that by calling kobject_init() and kobject_add() separately

Also make this cleanup registration a part of the create helper to
fix another mistake, as in the loop we were wrongly passing parent
kobject while registering cleanup action, and this resulted in some
undetected leaks.

libbpf: Fix perm errors for LDIMM_64_FULL_RANGE_OFF
Commit 728ff16791 ("libbpf: Add gating for arena globals relocation feature")
adds a feature flag for testing whether the running kernel supports LDIMM64
instructions with large direct offsets. Fix two edge cases that can
cause unexpected -EPERM errors in two ways:
1) The probe program used for the feature has type TRACEPOINT, but it's
possible the caller does not have permission to load it, even if it is
able to do so for generic BPF programs. Use the SOCKET_FILTER type
instead that requires fewer permissions. This does not affect the check
itself, which will always fail verification anyway.
2) The probe is triggered during bpf_object__collect_relos(), itself
called in bpf_object_open(), to compute the arena relocation offsets of
arena variables. However, the caller may not have permissions to load
BPF programs. This is the case in some systems with the bpftool calls made
by the BPF selftests during compilation, e.g., for skeleton generation.
Move all uses of the feature check to bpf_object_prepare() time instead.

Commit 728ff16791 ("libbpf: Add gating for arena globals relocation feature")
adds a feature gate check that loads a map and BPF program to
test the running kernel supports large direct offsets for LDIMM64
instructions. This check is currently used to calculate arena symbol
offsets during bpf_object__collect_relos, itself called by
bpf_object_open.
However, the program calling bpf_object_open may not have the permissions to
load maps and programs. This is the case with the BPF selftests, where
bpftool is invoked at compilation time during skeleton generation. This
causes errors as the feature gate unexpectedly fails with -EPERM.
Avoid this by moving all the use of the FEAT_LDIMM64_FULL_RANGE_OFF feature gate
to BPF object preparation time instead.

Commit 728ff16791 uses a PROG_TYPE_TRACEPOINT BPF test program to
check whether the running kernel supports large LDIMM64 offsets. The
feature gate incorrectly assumes that the program will fail at
verification time with one of two messages, depending on whether the
feature is supported by the running kernel. However,
PROG_TYPE_TRACEPOINT programs may fail to load before verification even
starts, e.g., if the shell does not have the appropriate capabilities.
Use a BPF_PROG_TYPE_SOCKET_FILTER program for the feature gate instead.
Also fix two minor issues. First, ensure the log buffer for the test is
initialized: Failing program load before verification led to libbpf dumping
uninitialized data to stdout. Also, ensure that close() is only called
for program_fd in the probe if the program load actually succeeded. The
call was currently failing silently with -EBADF most of the time.

- usb gadget function driver updates

that big, just lots of tiny coding style cleanups primarily in one

The spidev driver previously used two mutexes, spi_lock and buf_lock,
but acquired them in different orders depending on the code path:
write()/read(): buf_lock -> spi_lock
ioctl(): spi_lock -> buf_lock
This AB-BA locking pattern triggers lockdep warnings and can
cause real deadlocks:
WARNING: possible circular locking dependency detected
spidev_ioctl() -> mutex_lock(&spidev->buf_lock)
spidev_sync_write() -> mutex_lock(&spidev->spi_lock)
*** DEADLOCK ***
The issue is reproducible with a simple userspace program that
performs write() and SPI_IOC_WR_MAX_SPEED_HZ ioctl() calls from
separate threads on the same spidev file descriptor.
Fix this by simplifying the locking model and removing the lock
inversion entirely. spidev_sync() no longer performs any locking,
and all callers serialize access using spi_lock.
buf_lock is removed since its functionality is fully covered by
spi_lock, eliminating the possibility of lock ordering issues.
This removes the lock inversion and prevents deadlocks without
changing userspace ABI or behaviour.

Reason for this is that the s390 specific smp initialization code schedules
a work which rebuilds scheduling domains way before the scheduler is smp

The commit c8424e776b ("MODSIGN: Export module signature definitions")
replaced the dependency of KEXEC_SIG on SYSTEM_DATA_VERIFICATION with the
dependency on MODULE_SIG_FORMAT. This change disables KEXEC_SIG in s390
kernels built with MODULES=n if nothing else selects MODULE_SIG_FORMAT.
Furthermore, the signature verification in s390 kexec does not require
MODULE_SIG_FORMAT because it requires only the struct module_signature and,
therefore, does not depend on code in kernel/module_signature.c.
But making ARCH_SUPPORTS_KEXEC_SIG depend on SYSTEM_DATA_VERIFICATION is
also incorrect because it makes KEXEC_SIG available on s390 only if some
other arbitrary option (for instance a file system or device driver)
selects it directly or indirectly.
To properly make KEXEC_SIG available for s390 kernels built with MODULES=y
as well as MODULES=n _and_ also not depend on arbitrary options selecting
SYSTEM_DATA_VERIFICATION, set ARCH_SUPPORTS_KEXEC_SIG=y for s390 and select
SYSTEM_DATA_VERIFICATION when KEXEC_SIG=y.

On certain platforms (PowerNV systems without a power-mgt DT node),
cpuidle may register only a single idle state. In cases where that
single state is a polling state (state 0), the ladder governor may
incorrectly treat state 1 as the first usable state and pass an
out-of-bounds index. This can lead to a NULL enter callback being
invoked, ultimately resulting in a system crash.

nf_tables_addchain() publishes the chain to table->chains via
list_add_tail_rcu() (in nft_chain_add()) before registering hooks.
If nf_tables_register_hook() then fails, the error path calls
nft_chain_del() (list_del_rcu()) followed by nf_tables_chain_destroy()
with no RCU grace period in between.
This creates two use-after-free conditions:
1) Control-plane: nf_tables_dump_chains() traverses table->chains
under rcu_read_lock(). A concurrent dump can still be walking
the chain when the error path frees it.
2) Packet path: for NFPROTO_INET, nf_register_net_hook() briefly
installs the IPv4 hook before IPv6 registration fails. Packets
entering nft_do_chain() via the transient IPv4 hook can still be
dereferencing chain->blob_gen_X when the error path frees the
chain.
Add synchronize_rcu() between nft_chain_del() and the chain destroy
so that all RCU readers -- both dump threads and in-flight packet
evaluation -- have finished before the chain is freed.

Add a global static spinlock to serialize counter fetch+reset
operations, preventing concurrent dump-and-reset from underrunning
values.
The lock is taken before fetching the total so that two parallel
resets cannot both read the same counter values and then both
subtract them.
A global lock is used for simplicity since resets are infrequent.

lock later.

Normally, SoundWire core handles prepare sequencing automatically

there is no need to set the prepare bits. However, due to a hardware

The tests use the tc pedit action to modify the IPv4 source address
("pedit ex munge ip src set"), but the IP header checksum is not
recalculated after the modification. As a result, the modified packet
fails sanity checks in br_netfilter after bridging and is dropped,
which causes the test to fail.
Fix this by ensuring net.bridge.bridge-nf-call-iptables is set to 0
during the test execution. This prevents the bridge from passing
L2 traffic to netfilter, bypassing the checksum validation that
causes the test failure.

Depends on [n]: PRINTK [=n]
Selected by [y]:
- NETCONSOLE_DYNAMIC [=y] && NETDEVICES [=y] && NET_CORE [=y] && NETCONSOLE [=y] && SYSFS [=y] && CONFIGFS_FS [=y] && (NETCONSOLE [=y]!=y [=y] || CONFIGFS_FS [=y]!=m [=m])
In that configuration, the netconsole driver is useless anyway, so
avoid this with an added dependency that prevents CONFIG_NETCONSOLE
to be enabled without CONFIG_PRINTK.
Fixes: 60325c27d3 ("printk: Add execution context (task name/CPU) to printk_info")

Recently we were able to trigger a warning in the mdb_n_entries counting
code. Add tests that exercise different ways which used to trigger that
warning.
