objtool/klp: Allow new references to module exports
klp_reloc_needed() returns true for module exports to support late-module patching. However, clone_reloc_klp() unconditionally rejects symbols without a twin (i.e., new references added by the patch), even when the symbol is a known export from Module.symvers. Relax the check: allow new references to exported symbols by only erroring on !twin when there is no export. The export metadata from Module.symvers provides sufficient context to emit the klp-relocation without a twin. For a module export that isn't sufficient on its own though, as the resulting klp relocation will only be resolved at patch-enable time if the exporting module is loaded. If the original (unpatched) module already depends on the exporting module, the dependency is safe: the module loader ensures the dependency is satisfied before the patched module can be loaded, so the klp relocation target will exist. However, if the patch introduces a reference to a module that the original doesn't depend on, there is no such guarantee. The exporting module could be absent or could be unloaded at any time, leading to a relocation failure or use-after-free. So also add a build-time check: when a new symbol reference (no twin) targets a module export, verify that the original module already has at least one UNDEF symbol resolving to that same exporting module. If not, error out with a diagnostic message.

objtool/klp: Don't match local symbols against exports
While cloning a reloc, klp diff calls find_export() to determine whether
the referenced symbol is exported. That decides whether the reference
needs a klp reloc, which object the klp symbol belongs to, and whether
the symbol's data needs to be copied into the patch module.
But find_export() matches purely on symbol name, so a static function or
variable which happens to share its name with an export is mistaken for
a reference to that export:
- klp_reloc_needed() creates a klp reloc pointing at the exporting
module's symbol rather than the local one. For a vmlinux export it
skips the klp reloc altogether, leaving a normal reloc which the
module loader resolves to the vmlinux symbol.
- clone_reloc() treats the symbol as external and clones it without
its data, leaving a dangling reference.
- validate_special_section_klp_reloc() attributes a static branch or
call key to the wrong module, and for a vmlinux export skips the
unsupported-key check entirely.
Exports are always global, so ignore local symbols in find_export().

objtool/klp: Fix cross-module klp relocation section naming
A klp relocation section is .klp.rela.<objname>.<secname>, where objname
is the object being patched.
klp-build wrongly derives objname from where the referenced symbol
lives, not where it's referenced. For a cross-module reference like
patched can_isotp code calling can.ko's can_rx_unregister(), that gives
.klp.rela.can..text rather than .klp.rela.can_isotp..text. Unless the
patch happens to patch can.ko as well, the relocation never gets applied
and the call goes off into the weeds.
Name the intermediate section __klp_relocs.<objname> so post-link can
read the patched object's name from there.

objtool/klp: Explicitly disallow patching or referencing init code/data
Explicitly disallow the patching and referencing of init code/data. Otherwise it could potentially introduce some odd edge cases depending on whether the target object's init section has been freed yet (note that the init code still exists in the target module when doing late module patching). Such edge cases include sympos calculation and the patching and/or referencing of non-existent (init-freed) code/data. Not to mention the inherent differences in behavior that occur when the init code is only patched *some* of the time depending on module loading order or kernel config.

objtool/klp: Ignore replacement offset of empty x86 alternatives
An x86 alternative with an empty replacement, e.g. the second entry of
ALTERNATIVE_2("orig", "repl", ft1, "", ft2)
has a replacementlen of zero. Its replacement offset still gets a
relocation, but the label it points at is the end of the previous
replacement, which is also the beginning of the *next* alternative's
replacement. The value is meaningless; get_alt_entry() already ignores
it for that reason.
klp diff doesn't ignore it. When such an alternative belongs to a
changed function, cloning its relocations drags in the unrelated
neighboring replacement, along with everything that replacement
references. On an x86 clang/lto build an empty alternative in
meminfo_proc_show() pulled in the replacement of an alternative in
proc_kcore_init(), silently emitting a klp relocation against init text
which has long since been freed by the time the patch is applied.
Add arch_alt_ignore_new_reloc() and skip such relocations when cloning.
This has to be arch specific: on arm64 a zero-length replacement instead
identifies an alternative callback, whose replacement offset points at
the callback function and must be preserved.

objtool/klp: Fix size of empty special section entries
create_fake_symbols() sizes each ANNOTATE_DATA_SPECIAL entry from the
offset of the next annotation, falling back to the end of the section
for the last entry. But the last entry is detected by a zero size,
which also happens for an *empty* entry: ALTERNATIVE(oldinstr, "", ft)
still annotates its zero-length replacement, at the same offset as the
next entry's annotation.
So every empty replacement gets a fake symbol spanning the entire rest
of .altinstr_replacement. That's harmless today only because
find_symbol_containing() picks the smaller of two overlapping symbols.
Track whether a next annotation was found rather than inferring it from
the size. A zero-length fake symbol is fine: find_symbol_containing()
skips those, so the properly sized symbol at the same offset still wins.

objtool/klp: Fix vmlinux .klp.symid link error for .no_trim_symbol symbols
Testing klp-build with arm64 produced the following linker error during
the original kernel build:
`__notrim.1' referenced in section `.klp.symid' of vmlinux.o: defined in discarded section `.no_trim_symbol' of vmlinux.o
symbol_get() puts a static __notrim[] in .no_trim_symbol, which GCC
names __notrim.1, __notrim.2, etc. Two or more built-in translation
units calling symbol_get() thus produce duplicate names, resulting in
corresponding .klp.symid references which trigger the above error.
Add .no_trim_symbol to the discarded section list so its symbols don't
get symids.
Note this issue is not specific to arm64: it just needs two built-in
symbol_get() callers. arm64 trips over it easily because it has KVM
always compiled in vmlinux, whereas on x86 it's typically a module.

objtool: Replace __ASSEMBLY__ with __ASSEMBLER__ in header files
While the GCC and Clang compilers already define __ASSEMBLER__ automatically when compiling assembly code, __ASSEMBLY__ is a macro that only gets defined by the Makefiles in the kernel. This can be very confusing when switching between userspace and kernelspace coding, or when dealing with uapi headers that rather should use __ASSEMBLER__ instead. So let's standardize now on the __ASSEMBLER__ macro that is provided by the compilers. This is a completely mechanical patch (done with a simple "sed -i" statement).

objtool/klp: Fix symbol resolution for duplicate data symbols
find_sympos() calculates a sympos used by livepatch to disambiguate
duplicately-named symbols. For function symbols, there's a hack which
counts .text.unlikely symbols before other .text symbols, matching the
linker script's section ordering.
Not only is the hack fragile, data symbols can have the same problem.
So for example, adding a reference to pwq_cache in
ep_unregister_pollwait() can trigger a corrupt sympos and a relocation
to the wrong pwq_cache symbol in the livepatch module, resulting in a
crash or undefined behavior.
Remove the existing hack in favor of a fully deterministic solution,
using the new .klp.symid table to derive the symbol-to-id mapping from
the original vmlinux.o and the id-to-address mapping from the
corresponding vmlinux, which can then be used to determine the exact
sympos associated with the original vmlinux.
Modules don't need any special treatment: the .ko has the same
section/symbol ordering as the original whole-archive symbol table.

objtool/klp: Add .klp.symid for sympos disambiguation
Livepatch identifies a duplicate-named symbol by its position (sympos) among same-named kallsyms entries, which for vmlinux are counted in ascending address order in the final linked kernel. That order can't be reliably derived from vmlinux.o: the final link reorders sub-sections (.text.unlikely*, .data..*, etc). Bridge the gap with a new .klp.symid section which can be used to correlate symbols between vmlinux.o and vmlinux so that klp-diff can reliably determine the sympos. The table can't survive --gc-sections: keeping it alive would keep every duplicate-named symbol's section alive, so the reference kernel would stop matching the one which ships. klp-build rejects CONFIG_LD_DEAD_CODE_DATA_ELIMINATION instead. Nothing is lost today: x86_64 is the only HAVE_KLP_BUILD arch and doesn't select HAVE_LD_DEAD_CODE_DATA_ELIMINATION, arm64 and s390 have never selected it either, and on powerpc, it's still EXPERIMENTAL and disabled by every distro kernel. This is the build-time half of reliable vmlinux sympos computation; "objtool klp diff" will consume the table in a subsequent commit.

objtool/klp: Fix false module dependencies caused by dead relocs
When creating a klp reloc, klp-diff keeps the original relocation but
converts the referenced symbol to an UNDEF/WEAK placeholder tombstone
symbol, which gets fully disabled later by klp post-link. The tombstone
symbol is only needed to avoid confusing objtool when it does the final
run on the patch module.
However, for references to exported symbols, modpost sees the reference
to the tombstone symbol as a real reference to an exported symbol,
resulting in a false module dependency getting created.
Further, for a reference to a tombstone symbol which is exported into a
module namespace, e.g. via EXPORT_SYMBOL_FOR_KVM_INTERNAL(), modpost
can't satisfy the dependency, resulting in a warning like the following:
module ... uses symbol kvm_flush_remote_tlbs from namespace
module:kvm-amd,kvm-intel, but does not import it.
Rename the placeholder tombstone symbols to ".klp.tombstone.<name>" so
modpost no longer recognizes them.

objtool/klp: Normalize Module.symvers paths to module names
Module.symvers contains build-tree object paths as module identifiers
(e.g., "arch/x86/kvm/kvm") rather than runtime module names ("kvm").
Objtool's clone_reloc_klp() uses this field directly for exported
symbols, while unexported symbols correctly go through __find_modname().
This means that exported symbol relocations may land in a .klp.rela
section named with the build path rather than the module name. That is
a crash waiting to happen: the kernel's livepatch loader silently skips
this relocation because it doesn't match the expected klp_object name.
The unresolved relocation sits in the newly activated code, crashing
when executed.
Normalize export->mod at Module.symvers read time using the same logic
as __find_modname() (refactored into a shared normalize_modname()
helper).

objtool/klp: Fix module name normalization for paths with dots
When .modinfo has no "name=" tag, __find_modname() falls back to
converting the object's build-tree path to a runtime module name by
stripping directory components, converting '-' to '_' and truncating the
file extension.
It does all that in a single pass over the entire path, so the first dot
anywhere in the path ends the name. For an object built in a directory
whose name contains a dot, e.g. "drivers/foo-1.0/bar.o", the result is a
bogus module name.
Strip the directory components up front so only the basename is scanned
for the extension separator.

Pull vfs fixes from Christian Brauner:
"binfmt_misc:
- Don't let an 'F' entry pin its own instance.
An entry registered with 'F' opens its interpreter at registration
time and holds that file until the entry is freed, so an entry
nobody removes by hand is only closed once the binfmt_misc
superblock is shut down.
If the interpreter lives on a mount that keeps that superblock
alive the two pin each other and the file is never closed. That's
reachable by pointing the interpreter at the instance itself or by
using the instance as an overlayfs lower layer, and once the mount
namespace is gone there's nothing left to unregister through
either.
- Restore write access when removing an entry.
Registering with the MISC_FMT_OPEN_FILE flag opens the interpreter
via open_exec() which denies write access for as long as the entry
exists, but removal only did filp_close() and never restored it.
The inode's i_writecount stayed permanently negative and opening
the interpreter for writing kept failing with ETXTBSY long after
the entry was gone.
- Use exe_file_deny_write_access() for the interpreter clone so both
sides base their decision on the same mode.
- Reject a flag character as the field delimiter. create_entry() pads
the buffer with the delimiter so the field parsers terminate even
on a truncated string, but check_special_flags() consumes flag
characters instead of scanning for the delimiter.
If the delimiter is itself a flag character the padding stops
acting as a terminator and the scan keeps reading past the end of
the allocation. Such a registration was always rejected, just only
after the out of bounds read has already happened.
- Don't leak the user namespace when the mount fails.
bm_get_tree() hands its reference to get_tree_keyed() and sget_fc()
moves it into sb->s_fs_info, but generic_shutdown_super() only
calls ->put_super() from inside the if (sb->s_root) branch and
bm_fill_super() can fail before either s_root or s_op is in place.
Drop the reference in ->kill_sb() instead, which runs
unconditionally.
netfs:
- Clear PG_private_2 on a copy-to-cache append failure.
- Handle a rolling buffer allocation failure in single-object
writeback and drop the extra folio reference
netfs_write_folio_single() took before the append.
- Release the previously batched readahead folios when
rolling_buffer_load_from_ra() fails in
netfs_prepare_read_iterator()
- Fix the folio_queue ENOMEM in writeback by adding a mempool and
passing gfp flags into the rolling buffer helpers.
iomap:
- Add a separate bio_set for iomap_split_ioend(). It can split bios
that already come from iomap_ioend_bioset and deadlock once that
bioset is exhausted.
afs:
- Set call->async for an asynchronous afs_fs_fetch_data() the way
afs_fs_fetch_data64() already does.
- Subtract subreq->transferred from subreq->len in
afs_fs_fetch_data() rather than adding it.
- Fix a UAF when sending a message"

tracing fixes for v7.2:
- Reset dropped_count in mmio_reset_data() When mmio_reset_data() is called, it does not reset the dropped_count so that subsequent runs will have incorrect reporting. - Add NULL check for mmio_trace_array in logging functions The functions __trace_mmiotrace_rw() and __trace_mmiotrace_map() may have the 'tr' variable passed to it as NULL. But they both dereference it without checking if it is NULL first. - Check return value of __register_event() in trace_module_add_events() If __register_event() fails, the call after it (__add_event_to_tracers()) will create a file for it. If the module fails to load and its memory is freed, the file will still point to it and it will not be removed as the registering of the event did not complete. Only call __add_event_to_tracers() if the __register_event() was successful. - Fix false positive match in regex_match_full() The regex full matching uses a strncmp() to test against the match string and the value. It should not match if value is a prefix of the string to match. Check to make sure the length of the strings match before comparing. - Fix reader page read offset for remote buffers A page swapped in by __rb_get_reader_page_from_remote() retains its stale read offset, causing subsequent reads to skip events or read past valid data. - Fix memory leak of subbuf_ids in rb_allocate_cpu_buffer() Remote buffers allocate a subbuf_ids array.

ring-buffer: Fix subbuf_ids memory leak in rb_allocate_cpu_buffer() error path
In rb_allocate_cpu_buffer(), cpu_buffer->subbuf_ids is allocated using
kcalloc() when buffer->remote is non-NULL. If a subsequent page allocation
fails (e.g., ring_buffer_desc_page() returns NULL or rb_allocate_pages()
fails), execution jumps to fail_free_reader.
While __free(kfree) automatically frees the outer cpu_buffer structure
at scope exit, kfree(cpu_buffer) does not recursively free nested heap
pointers such as cpu_buffer->subbuf_ids, resulting in a memory leak.
Fix this by explicitly freeing cpu_buffer->subbuf_ids in the
fail_free_reader error unwinding path when cpu_buffer->remote is set.

mshv: Publish VP to pt_vp_array before installing the file descriptor
mshv_partition_ioctl_create_vp() called anon_inode_getfd() before
publishing the new VP into partition->pt_vp_array. anon_inode_getfd()
includes fd_install(), so the fd was live in current->files before the
publish ran.
A concurrent MSHV_RUN_VP ioctl on that fd does not serialise against the
in-progress MSHV_CREATE_VP — it takes vp->vp_mutex, not the partition
mutex. Once the VP starts running and traps, mshv_intercept_isr() can look
up partition->pt_vp_array[vp_index] and observe NULL, silently dropping the
intercept message.
Split the fd creation: reserve an fd with get_unused_fd_flags(), create the
file with anon_inode_getfile(), publish the VP via smp_store_release(), and
finally call fd_install() as the userspace-visibility commit point.

Drivers: hv: vmbus: add VTL2 redirect connection ID
VMBus sends CHANNELMSG_INITIATE_CONTACT through a Hyper-V message connection ID. Older protocol versions use VMBUS_MESSAGE_CONNECTION_ID, while protocol version 5.0 and newer normally use VMBUS_MESSAGE_CONNECTION_ID_4. For a VTL2 kernel using VMBus protocol 5.0 or newer, the host may expect INITIATE_CONTACT on either the redirect connection ID or VMBUS_MESSAGE_CONNECTION_ID_4. There is no capability indication that identifies which ID is active, so the driver must determine it at runtime. During VMBus negotiation, the redirect ID is tried first because it is used by VTL2 configurations with VMBus redirection enabled. If the redirect ID is unavailable, the host rejects it synchronously with HV_STATUS_INVALID_CONNECTION_ID, allowing fallback to the standard ID. Return a distinct error for an invalid Initiate Contact connection ID so this fallback does not mask other post-message failures or protocol-version rejections. Preserve the existing connection ID selection for older protocol versions or when running below VTL2.

mshv: Order pt_vp_array publish against irqfd assertion path
mshv_partition_ioctl_create_vp() initialises a VP struct (allocations,
mutex_init, init_waitqueue_head, page mappings) and then publishes the
pointer into partition->pt_vp_array. Several ISR paths read this array
locklessly: the intercept ISR, the two scheduler ISRs, and
mshv_try_assert_irq_fast() on the irqfd fast path.
Of these, only mshv_try_assert_irq_fast() can structurally race the
publish. It runs from an eventfd waker without holding pt_mutex, and
MSHV_IRQFD does not require the target lapic_apic_id (== vp_index) to
refer to an existing VP at registration time. A user can therefore
register an irqfd targeting a yet-to-be-created VP, then trigger
mshv_try_assert_irq_fast() concurrently with MSHV_CREATE_VP for the
same index. On weakly-ordered architectures the reader can observe a
non-NULL pointer in pt_vp_array before the initialising stores to the
VP struct become visible, leading to use of partially-initialised
fields (e.g. vp_register_page).
The other ISR readers cannot reach this race: the hypervisor will not
generate intercept or scheduler messages for a VP that has never been
told to run, and the user can only call MSHV_RUN_VP on the VP fd
returned by MSHV_CREATE_VP, which by construction is returned after
the publish. Leave those readers as plain loads.
Use smp_store_release() in mshv_partition_ioctl_create_vp() to publish
the pointer, and pair it with smp_load_acquire() in
mshv_try_assert_irq_fast(). On x86 these compile to plain accesses
under TSO; on ARM64 they emit one-instruction acquire/release barriers,
acceptable on this fast path.
The destroy-side path (destroy_partition() clearing pt_vp_array[i] to
NULL after kfree(vp)) has a separate ordering and lifetime concern
that is out of scope here.

mshv: Fix missing error code on VP allocation failure
In mshv_partition_ioctl_create_vp(), when kzalloc for the VP struct
fails, the code jumps to the cleanup path without setting ret. At that
point ret is 0 from the preceding successful mshv_vp_stats_map() call,
so the function returns success to userspace despite having failed to
create the VP. No fd is installed and no VP is registered in pt_vp_array,
but userspace has no way to know the operation failed.
Set ret to -ENOMEM before jumping to the cleanup path.

mshv: Fix level-triggered check on uninitialized data
In mshv_irqfd_assign(), the level-triggered validation for resample
irqfds checks irqfd_lapic_irq.lapic_control.level_triggered before
mshv_irqfd_update() has populated the field. Since the irqfd struct is
zero-allocated, level_triggered is always 0 at that point, causing the
check to always reject resample irqfds with -EINVAL. This makes
level-triggered interrupt resampling — used to avoid interrupt storms
with assigned devices — completely non-functional.
Move the check after the mshv_irqfd_update() call, which resolves the
IRQ routing entry and populates irqfd_lapic_irq with the actual trigger
mode.

mshv: Fix race in mshv_irqfd_deassign
mshv_irqfd_deactivate() and the hlist traversal of pt_irqfds_list
require pt->pt_irqfds_lock to be held, but mshv_irqfd_deassign()
omits it. This races with the EPOLLHUP path in mshv_irqfd_wakeup(),
which does take the lock before calling mshv_irqfd_deactivate().
Additionally, mshv_irqfd_deactivate() uses hlist_del() which poisons
the node pointers rather than resetting them. Since
mshv_irqfd_is_active() relies on hlist_unhashed() (checks pprev ==
NULL), a poisoned node still appears active. If a concurrent path calls
mshv_irqfd_deactivate() again on the same irqfd, the guard fails to
prevent a double hlist_del() on poisoned pointers.
Fix both issues:
- Add the missing spin_lock_irq/spin_unlock_irq around the list
traversal in mshv_irqfd_deassign(), matching mshv_irqfd_release().
- Use hlist_del_init() instead of hlist_del() so the node is properly
marked as unhashed after removal, making the is_active guard reliable.

mshv: Use kfree_rcu in mshv_portid_free
mshv_portid_free() uses synchronize_rcu() followed by kfree() to reclaim port table entries. This blocks the caller until a full RCU grace period elapses, which is unnecessary since the same module already uses the non-blocking kfree_rcu() pattern in mshv_port_table_fini(). Replace with kfree_rcu() to avoid the blocking wait and keep the reclamation strategy consistent across the file.
