It shouldn't be responsibility of memblock users to detect if they free
memory allocated from memblock late and should use memblock_free_late().
Make memblock_free() and memblock_phys_free() take care of late memory
freeing and drop memblock_free_late().

delay accounting started populating taskstats records with a valid version
field via fill_pid() and fill_tgid().
Later, commit ad4ecbcba728 ("[PATCH] delay accounting taskstats interface
send tgid once") changed the TGID exit path to send the cached
signal->stats aggregate directly instead of building the outgoing record
through fill_tgid(). Unlike fill_tgid(), fill_tgid_exit() only
accumulates accounting data and never initializes stats->version.
As a result, TGID exit notifications can reach userspace with version == 0
even though PID exit notifications and TASKSTATS_CMD_GET replies carry a
valid taskstats version.
This is easy to reproduce with `tools/accounting/getdelays.c`.
I have a small follow-up patch for that tool which:
1. increases the receive buffer/message size so the pid+tgid
combined exit notification is not dropped/truncated
2. prints `stats->version`.
With that patch, the reproducer is:
Terminal 1:
./getdelays -d -v -l -m 0
Terminal 2:
taskset -c 0 python3 -c 'import threading,time; t=threading.Thread(target=time.sleep,args=(0.1,)); t.start(); t.join()'
That produces both PID and TGID exit notifications for the same
process. The PID exit record reports a valid taskstats version, while
the TGID exit record reports `version 0`.
This patch (of 2):
Set stats->version = TASKSTATS_VERSION after copying the cached TGID
aggregate into the outgoing netlink payload so all taskstats records are
self-describing again.

Add a KUnit test module (CONFIG_LINEINFO_KUNIT_TEST) that verifies the
kallsyms lineinfo feature produces correct source file:line annotations in
stack traces.
Export sprint_backtrace() and sprint_backtrace_build_id() as GPL symbols
so the test module can exercise the backtrace APIs.

Replace the flat uncompressed parallel arrays (lineinfo_addrs[],
lineinfo_file_ids[], lineinfo_lines[]) with a block-indexed,
delta-encoded, ULEB128 varint compressed format.
The sorted address array has small deltas between consecutive entries
(typically 1-50 bytes), file IDs have high locality (delta often 0, same
file), and line numbers change slowly. Delta-encoding followed by ULEB128
varint compression shrinks most values from 4 bytes to 1.
Entries are grouped into blocks of 64. A small uncompressed block index
(first addr + byte offset per block) enables O(log(N/64)) binary search,
followed by sequential decode of at most 64 varints within the matching
block. All decode state lives on the stack -- zero allocations, still
safe for NMI/panic context.
Measured on a defconfig+debug x86_64 build (3,017,154 entries, 4,822
source files, 47,144 blocks):
Before (flat arrays):
lineinfo_addrs[] 12,068,616 bytes (u32 x 3.0M)
lineinfo_file_ids[] 6,034,308 bytes (u16 x 3.0M)
lineinfo_lines[] 12,068,616 bytes (u32 x 3.0M)
Total: 30,171,540 bytes (28.8 MiB, 10.0 bytes/entry)
After (block-indexed delta + ULEB128):
lineinfo_block_addrs[] 188,576 bytes (184 KiB)
lineinfo_block_offsets[] 188,576 bytes (184 KiB)
lineinfo_data[] 10,926,128 bytes (10.4 MiB)
Total: 11,303,280 bytes (10.8 MiB, 3.7 bytes/entry)
Savings: 18.0 MiB (2.7x reduction)

Add CONFIG_KALLSYMS_LINEINFO_MODULES, which extends the
CONFIG_KALLSYMS_LINEINFO feature to loadable kernel modules.
At build time, each .ko is post-processed by scripts/gen-mod-lineinfo.sh
(modeled on gen-btf.sh) which runs scripts/gen_lineinfo --module on the
.ko, generates a .mod_lineinfo section containing a compact binary table
of .text-relative offsets, file IDs, line numbers, and filenames, and
embeds it back into the .ko via objcopy.
At runtime, module_lookup_lineinfo() performs a binary search on the
module's .mod_lineinfo section, and __sprint_symbol() calls it for
addresses that fall within a module. The lookup is NMI/panic-safe (no
locks, no allocations) — the data lives in read-only module memory and
is freed automatically when the module is unloaded.
The gen_lineinfo tool gains --module mode which:
- Uses .text section address as base (ET_REL files have no _text symbol)
- Filters entries to .text-only (excludes .init.text/.exit.text)
- Handles libdw's ET_REL path-doubling quirk in make_relative()
- Outputs a flat binary-format section instead of named global symbols
Per-module overhead is approximately 10 bytes per DWARF line entry.

Patch series "kallsyms: embed source file:line info in kernel stack
traces", v4.
This series adds CONFIG_KALLSYMS_LINEINFO, which embeds source file:line
information directly in the kernel image so that stack traces annotate
every frame with the originating source location - no external tools, no
debug symbols at runtime, and safe to use in NMI/panic context.
Motivation
==========
The recent "slowly decommission bugzilla?" thread surfaced a recurring
problem: when users encounter kernel crashes they see stack traces like
`func+0x1ec/0x240` but have no way to identify which subsystem or
maintainer to contact. Richard Weinberger proposed building a database
mapping symbols to source files using nm/DWARF. Linus pointed to
scripts/decode_stacktrace.sh as the existing solution. But as the
discussion progressed, it became clear that decode_stacktrace.sh has
significant practical barriers that prevent it from being useful in the
common case.
Problems with scripts/decode_stacktrace.sh
==========================================
- Requires debug symbols: the script needs vmlinux with DWARF debug
info. Many distros don't retain debug symbols for older or security
kernels, and even when available, asking users to obtain matching
debuginfo packages is a significant hurdle.
- Requires toolchain: users need addr2line and nm installed.
- Version-matching requirement: debug symbols must exactly match the
running kernel binary.
What this series does
=====================
Patch 1: CONFIG_KALLSYMS_LINEINFO
At build time, a host tool (scripts/gen_lineinfo) reads DWARF .debug_line
from vmlinux, extracts address-to-file:line mappings, and embeds them as
sorted lookup tables in .rodata. At runtime, kallsyms_lookup_lineinfo()
binary-searches the table and __sprint_symbol() appends "(file:line)" to
each stack frame. NMI/panic- safe (no locks, no allocations),
KASLR-compatible.
Patch 2: CONFIG_KALLSYMS_LINEINFO_MODULES
Extends lineinfo to loadable modules. Each .ko gets a .mod_lineinfo
section embedded at build time. The module loader picks it up at load
time. Same zero-allocation, NMI-safe lookup.
Patch 3: delta compression
Block-indexed delta-encoding with LEB128 varints, implementing the
approach suggested by Juergen Gross in the RFC review. Reduces overhead
from ~44 MiB to ~11 MiB (~3.7 bytes/entry), addressing the primary size
concern from the RFC.
Patch 4: KUnit tests
30 KUnit tests covering the lineinfo lookup paths, delta-decode logic,
boundary conditions, and integration with the backtrace formatting APIs.

Size impact
===========
Measured with a Debian kernel config:
- bzImage: +3.6 MiB (14 MiB -> 18 MiB, +26%)
- Runtime memory: +5.9 MiB (text+data+bss)
- Code overhead: +5.0 KiB (.text, lookup functions only)
- Data overhead: +5.9 MiB (.data, lineinfo tables)
Lineinfo data breakdown:
- lineinfo_data (delta-compressed): 5,728 KiB (97%)
- lineinfo_block_addrs: 99 KiB
- lineinfo_block_offsets: 99 KiB
- lineinfo_filenames: 111 KiB
- lineinfo_file_offsets: 17 KiB
The ~5.9 MiB is after 2.7x delta compression; uncompressed would be ~16
MiB. This is a fraction of the cost of shipping full DWARF debug info
(hundreds of MiB), which distros must store and serve for every kernel
version.
For distros, maintaining debug symbol repositories is expensive: storage,
mirrors, and CDN bandwidth for hundreds of MiB per kernel build add up
quickly. A ~5.9 MiB increase in the kernel image itself is a modest cost
that eliminates the need for users to find, download, and version-match
debuginfo packages just to make a crash report useful.
For developers, the file:line annotations appear immediately in crash
traces - no post-processing with decode_stacktrace.sh needed.
This patch (of 4):
Add CONFIG_KALLSYMS_LINEINFO, which embeds a compact address-to-line
lookup table in the kernel image so stack traces directly print source
file and line number information:

At build time, a new host tool (scripts/gen_lineinfo) reads DWARF
.debug_line from vmlinux using libdw (elfutils), extracts all
address-to-file:line mappings, and generates an assembly file with sorted
parallel arrays (offsets from _text, file IDs, and line numbers). These
are linked into vmlinux as .rodata.
At runtime, kallsyms_lookup_lineinfo() does a binary search on the table
and __sprint_symbol() appends "(file:line)" to each stack frame. The
lookup uses offsets from _text so it works with KASLR, requires no locks
or allocations, and is safe in any context including panic.
The feature requires CONFIG_DEBUG_INFO (for DWARF data) and elfutils
(libdw-dev) on the build host.
Memory footprint measured with a 1852-option x86_64 config:
Table: 4,597,583 entries from 4,841 source files
lineinfo_addrs[] 4,597,583 x u32 = 17.5 MiB
lineinfo_file_ids[] 4,597,583 x u16 = 8.8 MiB
lineinfo_lines[] 4,597,583 x u32 = 17.5 MiB
file_offsets + filenames ~ 0.1 MiB
Total .rodata increase: ~ 44.0 MiB
vmlinux (stripped): 529 MiB -> 573 MiB (+44 MiB / +8.3%)
Note: this probably won't be something we roll into "production", but it
might be useful for the average user given the relatively low memory
footprint, in canary deployments for hyperscalers, or by default for folks
who run tests/fuzzing/etc.
Disclaimer: this was vibe coded over an afternoon with an AI coding
assistant.
The .config used for testing is a simple KVM guest configuration for
local development and testing.

When a child process exits, it sends exit_signal to its parent via
do_notify_parent(). The clone() syscall constructs exit_signal as:
(lower_32_bits(clone_flags) & CSIGNAL)
CSIGNAL is 0xff, so values in the range 65-255 are possible. However,
valid_signal() only accepts signals up to _NSIG (64 on x86_64). A
non-zero non-valid exit_signal acts the same as exit_signal == 0: the
parent process is not signaled when the child terminates.
The syzkaller reproducer triggers this by calling clone() with flags=0x80,
resulting in exit_signal = (0x80 & CSIGNAL) = 128, which exceeds _NSIG and
is not a valid signal.
The v1 of this patch added the check only in the clone() syscall handler,
which is incomplete. kernel_clone() has other callers such as
sys_ia32_clone() which would remain unprotected. Move the check to
kernel_clone() to cover all callers.
Since the valid_signal() check is now in kernel_clone() and covers all
callers including clone3(), the same check in copy_clone_args_from_user()
becomes redundant and is removed. The higher 32bits check for clone3() is
kept as it is clone3() specific.
Note that this is a user-visible change: previously, passing an invalid
exit_signal to clone() was silently accepted. The man page for clone()
does not document any defined behavior for invalid exit_signal values, so
rejecting them with -EINVAL is the correct behavior. It is unlikely that
any sane application relies on passing an invalid exit_signal.

Patch series "kdump: Enable LUKS-encrypted dump target support in ARM64
and PowerPC", v5.
CONFIG_CRASH_DM_CRYPT has been introduced to support LUKS-encrypted device
dump target by addressing two challenges [1],
- Kdump kernel may not be able to decrypt the LUKS partition. For some
machines, a system administrator may not have a chance to enter the
password to decrypt the device in kdump initramfs after the 1st kernel
crashes
- LUKS2 by default use the memory-hard Argon2 key derivation function
which is quite memory-consuming compared to the limited memory reserved
for kdump.
To also enable this feature for ARM64 and PowerPC, we need to add a device
tree property dmcryptkeys [2] as similar to elfcorehdr to pass the memory
address of the stored info of dm-crypt keys to the kdump kernel.
This patch (of 3):
When the vmcore dumping target is not a LUKS-encrypted target, it's
expected that there is no dm-crypt key thus no need to return -ENOENT.
Also print more logs in crash_load_dm_crypt_keys. The benefit is
arch-specific code can be more succinct.

Stop pinning modules indefinitely upon file handler registration.
Instead, dynamically increment the module reference count only when a live
update session actively uses the file handler (e.g., during preservation
or deserialization), and release it when the session ends.
This allows modules providing live update handlers to be gracefully
unloaded when no live update is in progress.

Change liveupdate_unregister_file_handler and liveupdate_unregister_flb to
return void instead of an error code. This follows the design principle
that unregistration during module unload should not fail, as the unload
cannot be stopped at that point.

To ensure that unregistration is always successful and doesn't leave
dangling resources, introduce auto-unregistration of FLBs: when a file
handler is unregistered, all FLBs associated with it are automatically
unregistered.
Introduce a new helper luo_flb_unregister_all() which unregisters all FLBs
