media: dvbdev: Use %pe format specifier
The %pe format specifier is designed to print error pointers. It prints
a symbolic error name (eg. -EINVAL) and it makes the code simpler by

media: vidtv: initialize local pointers upon transfer of memory ownership
vidtv_channel_si_init() creates a temporary list (program, service, event)
and ownership of the memory itself is transferred to the PAT/SDT/EIT
tables through vidtv_psi_pat_program_assign(),
vidtv_psi_sdt_service_assign(), vidtv_psi_eit_event_assign().
The problem here is that the local pointer where the memory ownership
transfer was completed is not initialized to NULL. This causes the
vidtv_psi_pmt_create_sec_for_each_pat_entry() function to fail, and
in the flow that jumps to free_eit, the memory that was freed by
vidtv_psi_*_table_destroy() can be accessed again by
vidtv_psi_*_event_destroy() due to the uninitialized local pointer, so it
is freed once again.
Therefore, to prevent use-after-free and double-free vulnerability,
local pointers must be initialized to NULL when transferring memory
ownership.

The code in dvb_demux.c has multiple instances where a variable is
assigned a value inside the conditional part of an 'if' statement.
This practice is prohibited by the Linux kernel coding style to avoid
potential bugs arising from accidental assignments (e.g., '=' instead
of '==').
This patch refactors these instances by moving the assignment out of
the 'if' statement and onto the preceding line. This makes the code
clearer, safer, and compliant with checkpatch.pl.
Additionally, a minor whitespace issue in a function signature is also
corrected. This is a purely stylistic change with no functional impact.

Pull tracing fixes from Steven Rostedt:
"The previous fix to trace_marker required updating trace_marker_raw as
well. The difference between trace_marker_raw from trace_marker is
that the raw version is for applications to write binary structures
directly into the ring buffer instead of writing ASCII strings. This
is for applications that will read the raw data from the ring buffer
and get the data structures directly. It's a bit quicker than using
the ASCII version.
Unfortunately, it appears that our test suite has several tests that
test writes to the trace_marker file, but lacks any tests to the
trace_marker_raw file (this needs to be remedied). Two issues came
about the update to the trace_marker_raw file that syzbot found:
- Fix tracing_mark_raw_write() to use per CPU buffer
The fix to use the per CPU buffer to copy from user space was
needed for both the trace_maker and trace_maker_raw file.
The fix for reading from user space into per CPU buffers properly
fixed the trace_marker write function, but the trace_marker_raw
file wasn't fixed properly. The user space data was correctly
written into the per CPU buffer, but the code that wrote into the
ring buffer still used the user space pointer and not the per CPU
buffer that had the user space data already written.
- Stop the fortify string warning from writing into trace_marker_raw
After converting the copy_from_user_nofault() into a memcpy(),
another issue appeared. As writes to the trace_marker_raw expects
binary data, the first entry is a 4 byte identifier. The entry
structure is defined as:
struct {
struct trace_entry ent;
int id;
char buf[];
};
The size of this structure is reserved on the ring buffer with:
size = sizeof(*entry) + cnt;
Then it is copied from the buffer into the ring buffer with:
memcpy(&entry->id, buf, cnt);
This use to be a copy_from_user_nofault(), but now converting it to
a memcpy() triggers the fortify-string code, and causes a warning.
The allocated space is actually more than what is copied, as the
cnt used also includes the entry->id portion. Allocating
sizeof(*entry) plus cnt is actually allocating 4 bytes more than
what is needed.

This is because fortify string sees that the size of entry->id is only 4
bytes, but it is writing more than that. But this is OK as the
dynamic_array is allocated to handle that copy.
The size allocated on the ring buffer was actually a bit too big:
size = sizeof(*entry) + cnt;
But cnt includes the 'id' and the buffer data, so adding cnt to the size
of *entry actually allocates too much on the ring buffer.

slab: fix barn NULL pointer dereference on memoryless nodes
Phil reported a boot failure once sheaves become used in commits 59faa4da7cd4 ("maple_tree: use percpu sheaves for maple_node_cache") and 3accabda4da1 ("mm, vma: use percpu sheaves for vm_area_struct cache"):
Linus decoded the stacktrace to get_barn() and get_node() and determined
that kmem_cache->node[numa_mem_id()] is NULL.
The problem is due to a wrong assumption that memoryless nodes only
exist on systems with CONFIG_HAVE_MEMORYLESS_NODES, where numa_mem_id()
points to the nearest node that has memory. SLUB has been allocating its
kmem_cache_node structures only on nodes with memory and so it does with
struct node_barn.
For kmem_cache_node, get_partial_node() checks if get_node() result is
not NULL, which I assumed was for protection from a bogus node id passed
to kmalloc_node() but apparently it's also for systems where
numa_mem_id() (used when no specific node is given) might return a
memoryless node.
Fix the sheaves code the same way by checking the result of get_node()
and bailing out if it's NULL. Note that cpus on such memoryless nodes
will have degraded sheaves performance, which can be improved later,
preferably by making numa_mem_id() work properly on such systems.

kbuild: Use '--strip-unneeded-symbol' for removing module device table symbols
After commit 5ab23c7923a1 ("modpost: Create modalias for builtin
modules"), relocatable RISC-V kernels with CONFIG_KASAN=y start failing
when attempting to strip the module device table symbols:
riscv64-linux-objcopy: not stripping symbol `__mod_device_table__kmod_irq_starfive_jh8100_intc__of__starfive_intc_irqchip_match_table' because it is named in a relocation
make[4]: *** [scripts/Makefile.vmlinux:97: vmlinux] Error 1
The relocation appears to come from .LASANLOC5 in .data.rel.local:
This section appears to come from GCC for including additional
information about global variables that may be protected by KASAN.
There appears to be no way to opt out of the generation of these symbols
through either a flag or attribute. Attempting to remove '.LASANLOC*'
with '--strip-symbol' results in the same error as above because these
symbols may refer to (thus have relocation between) each other.
Avoid this build breakage by switching to '--strip-unneeded-symbol' for
removing __mod_device_table__ symbols, as it will only remove the symbol
when there is no relocation pointing to it. While this may result in a
little more bloat in the symbol table in certain configurations, it is
not as bad as outright build failures.

Merge patch series "kbuild: Fixes for fallout from recent modules.builtin.modinfo series"
This is a series to address some problems that were exposed by the
recent modules.builtin.modinfo series that landed in commit c7d3dd9163e6
("Merge patch series "Add generated modalias to
modules.builtin.modinfo"").
The third patch is not directly related to the aforementioned series, as
the warning it fixes happens prior to the series but commit 8d18ef04f940
("s390: vmlinux.lds.S: Reorder sections") from the series creates
conflicts in this area, so I included it here.
s390/vmlinux.lds.S: Move .vmlinux.info to end of allocatable sections
When building s390 defconfig with binutils older than 2.32, there are
several warnings during the final linking stage:
s390-linux-ld: .tmp_vmlinux1: warning: allocated section `.got.plt' not in segment
s390-linux-ld: .tmp_vmlinux2: warning: allocated section `.got.plt' not in segment
s390-linux-ld: vmlinux.unstripped: warning: allocated section `.got.plt' not in segment
s390-linux-objcopy: vmlinux: warning: allocated section `.got.plt' not in segment
s390-linux-objcopy: st7afZyb: warning: allocated section `.got.plt' not in segment
binutils commit afca762f598 ("S/390: Improve partial relro support for
64 bit") [1] in 2.32 changed where .got.plt is emitted, avoiding the
warning.
The :NONE in the .vmlinux.info output section description changes the
segment for subsequent allocated sections. Move .vmlinux.info right
above the discards section to place all other sections in the previously
defined segment, .data.
Prior to binutils commit c12d9fa2afe ("Support objcopy
--remove-section=.relaFOO") [1] in 2.32, stripping relocation sections
required the trailing period (i.e., '.rel.*') to work properly.
After commit 3e86e4d74c04 ("kbuild: keep .modinfo section in
vmlinux.unstripped"), there is an error with binutils 2.31.1 or earlier
because these sections are not properly removed:
s390-linux-objcopy: st6tO8Ev: symbol `.modinfo' required but not present
s390-linux-objcopy:st6tO8Ev: no symbols
Add the old pattern to resolve this issue (along with a comment to allow
cleaning this when binutils 2.32 or newer is the minimum supported
version). While the aforementioned kbuild change exposes this, the
pattern was originally changed by commit 71d815bf5dfd ("kbuild: Strip
runtime const RELA sections correctly"), where it would still be
incorrect with binutils older than 2.32.
kbuild: Restore pattern to avoid stripping .rela.dyn from vmlinux
Commit 0ce5139fd96e ("kbuild: always create intermediate
vmlinux.unstripped") removed the pattern to avoid stripping .rela.dyn
sections added by commit e9d86b8e17e7 ("scripts: Do not strip .rela.dyn
section"). Restore it so that .rela.dyn sections remain in the final
vmlinux.

selftests/bpf: Add test for unpinning htab with internal timer struct
Add test to verify that unpinning hash tables containing internal timer
structures does not trigger context warnings.
Each subtest (timer_prealloc and timer_no_prealloc) can trigger the
context warning when unpinning, but the warning cannot be triggered
twice within a short time interval (a HZ), which is expected behavior.
KaFai Wan [Wed, 8 Oct 2025 10:26:26 +0000 (18:26 +0800)]
bpf: Avoid RCU context warning when unpinning htab with internal structs
When unpinning a BPF hash table (htab or htab_lru) that contains internal
structures (timer, workqueue, or task_work) in its values, a BUG warning
is triggered:
BUG: sleeping function called from invalid context at kernel/bpf/hashtab.c:244
in_atomic(): 1, irqs_disabled(): 0, non_block: 0, pid: 14, name: ksoftirqd/0
...
The issue arises from the interaction between BPF object unpinning and
RCU callback mechanisms:
1. BPF object unpinning uses ->free_inode() which schedules cleanup via
call_rcu(), deferring the actual freeing to an RCU callback that
executes within the RCU_SOFTIRQ context.
2. During cleanup of hash tables containing internal structures,
htab_map_free_internal_structs() is invoked, which includes
cond_resched() or cond_resched_rcu() calls to yield the CPU during
potentially long operations.
However, cond_resched() or cond_resched_rcu() cannot be safely called from
atomic RCU softirq context, leading to the BUG warning when attempting
to reschedule.
Fix this by changing from ->free_inode() to ->destroy_inode() and rename
bpf_free_inode() to bpf_destroy_inode() for BPF objects (prog, map, link).
This allows direct inode freeing without RCU callback scheduling,
avoiding the invalid context warning.

Turned out certain clearly invalid values passed in xdp_desc from
userspace can pass xp_{,un}aligned_validate_desc() and then lead
to UBs or just invalid frames to be queued for xmit.
desc->len close to ``U32_MAX`` with a non-zero pool->tx_metadata_len
can cause positive integer overflow and wraparound, the same way low
enough desc->addr with a non-zero pool->tx_metadata_len can cause
negative integer overflow. Both scenarios can then pass the
validation successfully.
This doesn't happen with valid XSk applications, but can be used
to perform attacks.
Always promote desc->len to ``u64`` first to exclude positive
overflows of it. Use explicit check_{add,sub}_overflow() when
validating desc->addr (which is ``u64`` already).
bloat-o-meter reports a little growth of the code size:

xsk_tx_peek_release_desc_batch 973 1002 +29
xsk_generic_xmit 3148 3132 -16
but hopefully this doesn't hurt the performance much.
