Persistent buffer cleanups and simplifications for v6.15:
It was mistaken that the physical memory returned from "reserve_mem" had to
be vmap()'d to get to it from a virtual address. But reserve_mem already
maps the memory to the virtual address of the kernel so a simple
phys_to_virt() can be used to get to the virtual address from the physical
memory returned by "reserve_mem". With this new found knowledge, the
code can be cleaned up and simplified.
- Enforce that the persistent memory is page aligned
As the buffers using the persistent memory are all going to be
mapped via pages, make sure that the memory given to the tracing
infrastructure is page aligned. If it is not, it will print a warning
and fail to map the buffer.
- Use phys_to_virt() to get the virtual address from reserve_mem
Instead of calling vmap() on the physical memory returned from
"reserve_mem", use phys_to_virt() instead.
As the memory returned by "memmap" or any other means where a physical
address is given to the tracing infrastructure, it still needs to
be vmap(). Since this memory can never be returned back to the buddy
allocator nor should it ever be memmory mapped to user space, flag
this buffer and up the ref count. The ref count will keep it from
ever being freed, and the flag will prevent it from ever being memory
mapped to user space.
- Use vmap_page_range() for memmap virtual address mapping
For the memmap buffer, instead of allocating an array of struct pages,
assigning them to the contiguous phsycial memory and then passing that to
vmap(), use vmap_page_range() instead
- Replace flush_dcache_folio() with flush_kernel_vmap_range()
Instead of calling virt_to_folio() and passing that to
flush_dcache_folio(), just call flush_kernel_vmap_range() directly.
This also fixes a bug where if a subbuffer was bigger than PAGE_SIZE
only the PAGE_SIZE portion would be flushed.

"Set of fixes/updates for io_uring that should go into this release.
The ublk bits could've gone via either tree - usually I put them in
block, but they got a bit mixed this series with the zero-copy
supported that ended up dipping into both trees.
This contains:
- Fix for sendmsg zc, include in pinned pages accounting like we do
for the other zc types
- Series for ublk fixing request aborting, doing various little
cleanups, fixing some zc issues, and adding queue_rqs support
- Another ublk series doing some code cleanups
- Series cleaning up the io_uring send path, mostly in preparation
for registered buffers
- Series doing little MSG_RING cleanups
- Fix for the newly added zc rx, fixing len being 0 for the last
invocation of the callback
- Add vectored registered buffer support for ublk. With that, then
ublk also supports this feature in the kernel revision where it
could generically introduced for rw/net
- A bunch of selftest additions for ublk. This is the majority of the
diffstat
- Silence a KCSAN data race warning for io-wq
- Various little cleanups and fixes"

bcachefs fixes for 6.15-rc1
More notable fixes:
- Fix for striping behaviour on tiering filesystems where replicas
exceeds durability on destination target
- Fix a race in device removal where deleting alloc info races with the
discard worker
- Some small stack usage improvements: this is just enough for KMSAN
builds to not blow the stack, more is queued up for 6.16.

tracing fixes for 6.15
- Fix build error when CONFIG_PROBE_EVENTS_BTF_ARGS is not enabled The tracing of arguments in the function tracer depends on some functions that are only defined when PROBE_EVENTS_BTF_ARGS is enabled. In fact, PROBE_EVENTS_BTF_ARGS also depends on all the same configs as the function argument tracing requires. Just have the function argument tracing depend on PROBE_EVENTS_BTF_ARGS. - Free module_delta for persistent ring buffer instance When an instance holds the persistent ring buffer, it allocates a helper array to hold the deltas between where modules are loaded on the last boot and the current boot. This array needs to be freed when the instance is freed. - Add cond_resched() to loop in ftrace_graph_set_hash() The hash functions in ftrace loop over every function that can be enabled by ftrace. This can be 50,000 functions or more. This loop is known to trigger soft lockup warnings and requires a cond_resched(). The loop in ftrace_graph_set_hash() was missing it. - Fix the event format verifier to include "%*p.." arguments To prevent events from dereferencing stale pointers that can happen if a trace event uses a dereferece pointer to something that was not copied into the ring buffer and can be freed by the time the trace is read, a verifier is called. At boot or module load, the verifier scans the print format string for pointers that can be dereferenced and it checks the arguments to make sure they do not contain something that can be freed. The "%*p" was not handled, which would add another argument and cause the verifier to not only not verify this pointer, but it will look at the wrong argument for every pointer after that. - Fix mcount sorttable building for different endian type target When modifying the ELF file to sort the mcount_loc table in the sorttable.c code, the endianess of the file and the host is used to determine if the bytes need to be swapped when calculations are done. A change was made to the sorting of the mcount_loc that read the values from the ELF file into an array and the swap happened on the filling of the array. But one of the calculations of the array still did the swap when it did not need to. This caused building on a little endian machine for a big endian target to not find the mcount function in the 'nm' table and it zeroed it out, causing there to be no functions available to trace. - Add goto out_unlock jump to rv_register_monitor() on error path One of the error paths in rv_register_monitor() just returned the error when it should have jumped to the out_unlock label to release the mutex. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCZ+2tyBQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qjPYAPwJDti6nHTqheFwIa1WzJ3yC2tKRYKt 1E5PYW/2Ct5NmwEAqgg3TvJppXHymVdutLghhGFnlBnyTWMI+KIhparSBw8= =NFM5 -----END PGP SIGNATURE----- Merge tag 'trace-v6.15-2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing fixes from Steven Rostedt: - Fix build error when CONFIG_PROBE_EVENTS_BTF_ARGS is not enabled The tracing of arguments in the function tracer depends on some functions that are only defined when PROBE_EVENTS_BTF_ARGS is enabled.

bcachefs: Fix "journal stuck" during recovery
If we crash when the journal pin fifo is completely full - i.e. we're at the maximum number of dirty journal entries - that may put us in a sticky situation in recovery, as journal replay will need to be able to open new journal entries in order to get going. bch2_fs_journal_start() already had provisions for resizing the journal pin fifo if needed, but it needs a fudge factor to ensure there's room for journal replay.

bcachefs: backpointer_get_key: check for null from peek_slot()
peek_slot() doesn't normally return bkey_s_c_null - except when we ask for a key at a btree level that doesn't exist, which can happen here. We might want to revisit this, but we'll have to look over all the places where we use peek_slot() on interior nodes. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev> |

bcachefs: Fix check_snapshot_exists() restart handling
Codepaths that create entries in the snapshots btree currently call bch2_mark_snapshot(), which updates the in-memory snapshot table, before transaction commit. This is because bch2_mark_snapshot() is an atomic trigger, run with btree write locks held, and isn't allowed to fail - but it might need to reallocate the table, hence we call it early when we're still allowed to fail. This is generally harmless - if we fail, we'll have left an entry in the snapshots table around, but nothing will reference it and it'll get overwritten if reused by another transaction. But check_snapshot_exists(), which reconstructs snapshots when the snapshots btree has been corrupted or lost, was erronously rechecking if the snapshot exists inside the transaction commit loop - so on transaction restart (in this case mem_realloced), the second iteration would return without repairing. This code needs some cleanup: splitting out a "maybe realloc snapshots table" helper would have avoided this, that will be in the next patch.

bcachefs: Fix scheduling while atomic from logging changes
Two fixes from the recent logging changes: bch2_inconsistent(), bch2_fs_inconsistent() be called from interrupt context, or with rcu_read_lock() held. The one syzbot found is in bch2_bkey_pick_read_device bch2_dev_rcu bch2_fs_inconsistent We're starting to switch to lift the printbufs up to higher levels so we can emit better log messages and print them all in one go (avoid garbling), so that conversion will help with spotting these in the future; when we declare a printbuf it must be flagged if we're in an atomic context.

block: don't grab elevator lock during queue initialization
->elevator_lock depends on queue freeze lock, see block/blk-sysfs.c. queue freeze lock depends on fs_reclaim. So don't grab elevator lock during queue initialization which needs to call kmalloc(GFP_KERNEL), and we can cut the dependency between ->elevator_lock and fs_reclaim, then the lockdep warning can be killed. This way is safe because elevator setting isn't ready to run during queue initialization. There isn't such issue in __blk_mq_update_nr_hw_queues() because memalloc_noio_save() is called before acquiring elevator lock.

selftests/bpf: Fix verifier_private_stack test failure

selftests/bpf: Fix verifier_bpf_fastcall test
Commit [1] moves percpu data on x86 from address 0x000... to address
0xfff...
Before [1]:
159020: 0000000000030700 0 OBJECT GLOBAL DEFAULT 23 pcpu_hot
After [1]:
152602: ffffffff83a3e034 4 OBJECT GLOBAL DEFAULT 35 pcpu_hot
As a result, verifier_bpf_fastcall tests should now expect a negative
value for pcpu_hot, IOW, the disassemble should show "r=" instead of
"w=".
Fix this in the test.
Note that, a later change created a new variable "cpu_number" for
bpf_get_smp_processor_id() [2]. The inlining logic is updated properly
as part of this change, so there is no need to fix anything on the
kernel side.

The change in struct file [1] moved f_ref to the 3rd cache line.
It made *(u64 *)file dereference invalid from the verifier point of view,
because btf_struct_walk() walks into f_lock field, which is 4-byte long.
Fix the selftests to deference the file pointer as a 4-byte access.

xsk: Fix __xsk_generic_xmit() error code when cq is full
When the cq reservation is failed, the error code is not set which is
initialized to zero in __xsk_generic_xmit(). That means the packet is not
send successfully but sendto() return ok.
Considering the impact on uapi, return -EAGAIN is a good idea. The cq is
full usually because it is not released in time, try to send msg again is
appropriate.
The bug was at the very early implementation of xsk, so the Fixes tag
targets the commit that introduced the changes in
xsk_cq_reserve_addr_locked where this fix depends on.

Staging driver updates for 6.15-rc1
Here is the big set of staging driver cleanups and updates for 6.15-rc1.
As expected, with the introduction of the gpib drivers, loads of
cleanups and fixes showed up, with the huge majority of changes being
for that chunk of drivers. This is good and shows that the community
can fix up things in public when asked to. Also included in here are:
- small sm750fb cleanups
- tiny rtl8723bs cleanups
- more vchiq_arm cleanups and changes, hopefully this will get out of
staging soon.
All of these have been in linux-next for almost 2 weeks now with no

More ACPI updates for 6.15-rc1
- Extend the Lenovo Yoga Tab 3 ACPI quirk to skip GPIO event-handlers
along with ACPI AC and battery which makes it work with Linux when
started in the Windows mode (Hans de Goede).
- Prevent the ACPI processor idle driver from being used on systems
without _CST and with invalid C2/C3 in FADT in order to restore its
previous (and expected) behavior that has been altered inadvertently
by a recent code change (Giovanni Gherdovich).
- Skip ACPI IRQ override on ASUS Vivobook 14 X1404VAP to make the
internal keyboard work on it (Paul Menzel).
- Make the ACPI backlight driver handle fetching EDID passed as
ACPI_TYPE_PACKAGE which is not specification-compliant, but
has been encountered in the field (Gergo Koteles).
- Simplify the aggregation of choices in the ACPI platform-profile
driver which has been unlocked by recent modifications of that
driver (Kurt Borja).
- Use str_enabled_disabled() instead of hardcoded strings in the ACPI
code related to NUMA (Thorsten Blum).
- Add Intel OC Watchdog device IDs to non-PNP device list to prevent
PNP from claiming the devices that carry these IDs in which case
non-PNP drivers cannot bind to them (Diogo Ivo).

Pull more ACPI updates from Rafael Wysocki:
"These are fixes and cleanups on top of the previous ACPI material for
6.15-rc1 merged recently:
- Extend the Lenovo Yoga Tab 3 ACPI quirk to skip GPIO event-handlers
along with ACPI AC and battery which makes it work with Linux when
started in the Windows mode (Hans de Goede)
- Prevent the ACPI processor idle driver from being used on systems
without _CST and with invalid C2/C3 in FADT in order to restore its
previous (and expected) behavior that has been altered
inadvertently by a recent code change (Giovanni Gherdovich)
- Skip ACPI IRQ override on ASUS Vivobook 14 X1404VAP to make the
internal keyboard work on it (Paul Menzel)
- Make the ACPI backlight driver handle fetching EDID passed as
ACPI_TYPE_PACKAGE which is not specification-compliant, but has
been encountered in the field (Gergo Koteles)
- Simplify the aggregation of choices in the ACPI platform-profile
driver which has been unlocked by recent modifications of that
driver (Kurt Borja)
- Use str_enabled_disabled() instead of hardcoded strings in the ACPI
code related to NUMA (Thorsten Blum)
- Add Intel OC Watchdog device IDs to non-PNP device list to prevent
PNP from claiming the devices that carry these IDs in which case
non-PNP drivers cannot bind to them (Diogo Ivo)"

TDX guests aren't expected to use the HLT instruction directly. It causes a virtualization exception (#VE). While the #VE _can_ be handled, the current handling is slow and buggy and the easiest thing is just to avoid HLT in the first place. Plus, the kernel already has paravirt infrastructure that makes it relatively painless. Make TDX guests require paravirt and add some TDX-specific paravirt handlers which avoid HLT in the normal halt routines. Also add a warning in case another HLT sneaks in. There was a report that this leads to a "major performance improvement" on specjbb2015, probably because of the extra #VE overhead or missed wakeups from the buggy HLT handling" * tag 'x86_tdx_for_6.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/tdx: Emit warning if IRQs are enabled during HLT #VE handling x86/tdx: Fix arch_safe_halt() execution for TDX VMs x86/paravirt: Move halt paravirt calls under CONFIG_PARAVIRT |
