kprobes: Skip clearing aggrprobe's post_handler in kprobe-on-ftrace case
In __unregister_kprobe_top(), if the currently unregistered probe has
post_handler but other child probes of the aggrprobe do not have
post_handler, the post_handler of the aggrprobe is cleared. If this is
a ftrace-based probe, there is a problem. In later calls to
disarm_kprobe(), we will use kprobe_ftrace_ops because post_handler is
NULL. But we're armed with kprobe_ipmodify_ops. This triggers a WARN in
__disarm_kprobe_ftrace() and may even cause use-after-free:
Failed to disarm kprobe-ftrace at kernel_clone+0x0/0x3c0 (error -2)

For the kprobe-on-ftrace case, we keep the post_handler setting to

can disarm it correctly.

tracing/eprobe: Fix memory leak of filter string
The filter string doesn't get freed when a dynamic event is deleted. If a
filter is set, then memory is leaked:

Additionally, in __trace_eprobe_create() function, if an error occurs after
the call to trace_eprobe_parse_filter(), which allocates the filter string,
then memory is also leaked. That can be reproduced by creating the same
event probe twice:

tracing: kprobe: Fix potential null-ptr-deref on trace_array in kprobe_event_gen_test_exit()
When test_gen_kprobe_cmd() failed after kprobe_event_gen_cmd_end(), it
will goto delete, which will call kprobe_event_delete() and release the
corresponding resource. However, the trace_array in gen_kretprobe_test
will point to the invalid resource. Set gen_kretprobe_test to NULL
after called kprobe_event_delete() to prevent null-ptr-deref.

tracing: kprobe: Fix potential null-ptr-deref on trace_event_file in kprobe_event_gen_test_exit()
When trace_get_event_file() failed, gen_kretprobe_test will be assigned
as the error code. If module kprobe_event_gen_test is removed now, the
null pointer dereference will happen in kprobe_event_gen_test_exit().
Check if gen_kprobe_test or gen_kretprobe_test is error code or NULL
before dereference them.

ring-buffer: Include dropped pages in counting dirty patches
The function ring_buffer_nr_dirty_pages() was created to find out how many
pages are filled in the ring buffer. There's two running counters. One is
incremented whenever a new page is touched (pages_touched) and the other
is whenever a page is read (pages_read). The dirty count is the number
touched minus the number read. This is used to determine if a blocked task
should be woken up if the percentage of the ring buffer it is waiting for
is hit.
The problem is that it does not take into account dropped pages (when the
new writes overwrite pages that were not read). And then the dirty pages
will always be greater than the percentage.
This makes the "buffer_percent" file inaccurate, as the number of dirty
pages end up always being larger than the percentage, event when it's not
and this causes user space to be woken up more than it wants to be.
Add a new counter to keep track of lost pages, and include that in the
accounting of dirty pages so that it is actually accurate.

tracing/ring-buffer: Have polling block on watermark
Currently the way polling works on the ring buffer is broken. It will
return immediately if there's any data in the ring buffer whereas a read
will block until the watermark (defined by the tracefs buffer_percent file)
is hit.
That is, a select() or poll() will return as if there's data available,
but then the following read will block. This is broken for the way
select()s and poll()s are supposed to work.
Have the polling on the ring buffer also block the same way reads and
splice does on the ring buffer.

ALSA: memalloc: Try dma_alloc_noncontiguous() at first
The latest fix for the non-contiguous memalloc helper changed the
allocation method for a non-IOMMU system to use only the fallback
allocator. This should have worked, but it caused a problem sometimes
when too many non-contiguous pages are allocated that can't be treated
by HD-audio controller.
As a quirk workaround, go back to the original strategy: use
dma_alloc_noncontiguous() at first, and apply the fallback only when
it fails, but only for non-IOMMU case.
We'll need a better fix in the fallback code as well, but this
workaround should paper over most cases.

ata fixes for 6.1-rc5
Several libata generic code fixes for rc5:
- Add missing translation of the SYNCHRONIZE CACHE 16 scsi command as
this command is mandatory for host-managed ZBC drives. The lack of
support for it in libata-scsi was causing issues with some
passthrough applications using ZBC drives (from Shin'ichiro).
- Fix the error path of libata-transport host, port, link and device
attributes initialization (from Yingliang).
- Prevent issuing new commands to a drive that is in the NCQ error
state and undergoing recovery (From Niklas). This bug went unnoticed
for a long time as commands issued to a drive in error state are
aborted immediately and retried by the scsi layer, hiding the useless
abort-and-retry sequence.

arm64 fixes:
- Another fix for rodata=full. Since rodata= is not a simple boolean on arm64 (accepting 'full' as well), it got inadvertently broken by changes in the core code. If rodata=on is the default and rodata=off is passed on the kernel command line, rodata_full is never disabled. - Fix gcc compiler warning of shifting 0xc0 into bits 31:24 without an explicit conversion to u32 (triggered by the AMPERE1 MIDR definition). - Include asm/ptrace.h in asm/syscall_wrapper.h to fix an incomplete struct pt_regs type causing the BPF verifier to refuse to load a tracing program which accesses pt_regs. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEE5RElWfyWxS+3PLO2a9axLQDIXvEFAmNu1ZQACgkQa9axLQDI XvHdaQ/+NmdLFZuAbajhpV3NTmiC6oJmPZ9oGKxtBRGoHmH6WxoyB1X3Dj9ZMGBc qZ1mUohHHwf+xWtX85aPUx4aJKImFuqSOU4MF5gectzXFEr4jR2nx5CYBaRmG+0d axAUHIID4xWozid79KFUR46myG9GhTv8EGMlrY9VKY2GsFSD/EtNTQZhq+ISc05N SQAkHN3iiIJhitgTtxxA2jQ8sEOvq41N4VRj4trNUnAp5Gis4nnl9KGpcayN/60z 8/9IGwcaLpnQnlf74E74y53Tfq8ZHSpiNcl3J5Mk1eMNrbkFePakyH/OtpHHYiZ0 /Y1cqUqvK2oZODE1Ro4mBMFLq3+lFMedla5S0jZtjApYnJ8MmUqFQwvJHIn0K02h oH1OstQtYLUINTF3k1+TaYnmFjenx1eOJ/tdLjkcgI9WFbAYcqu1Z4bcO0HR0fqj 7d7HKCElHg+KIQBTfDtLvO1lNRvdpZYWe5uN3ItzPpYqrah4haHPJXPxcxVChkMv A445kWMX5pV7CTNzlkrGgWjWkF8EwJ+lgr/xASrpHPxW80cZ7b+eg2lFkU0fptsz FoHdUduGDB91hHo/k0Adx2gaS37SNOcBczr/1xFcId1ZpcxWwuBM1JeEDz1ccRDR P9qKykOn6sQ8ykQGDIlyY9Hgaz8KgihT2VDixRyY0NNGq0XO4LM= =W6FH -----END PGP SIGNATURE----- Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux Pull arm64 fixes from Catalin Marinas: - Another fix for rodata=full.

ata: libata-core: do not issue non-internal commands once EH is pending
While the ATA specification states that a device should return command aborted for all commands queued after the device has entered error state, since ATA only keeps the sense data for the latest command (in non-NCQ case), we really don't want to send block layer commands to the device after it has entered error state. (Only ATA EH commands should be sent, to read the sense data etc.) Currently, scsi_queue_rq() will check if scsi_host_in_recovery() (state is SHOST_RECOVERY), and if so, it will _not_ issue a command via: scsi_dispatch_cmd() -> host->hostt->queuecommand() (ata_scsi_queuecmd()) -> __ata_scsi_queuecmd() -> ata_scsi_translate() -> ata_qc_issue() Before commit |

- minor updates to defconfigs.
- Remove CONFIG_DEBUG_INFO_BTF from all defconfigs and add btf.config
addon config file. It significantly decreases compile time and allows
quickly enabling that option into the current kernel config.
- Add kasan.config addon config file which allows to easily enable
KASAN into the current kernel config.
- binutils commit 906f69cf65da ("IBM zSystems: Issue error for *DBL

"This is a pretty large diffstat for this time of the release. The main
culprit is a reorganization of the AMD assembly trampoline, allowing
percpu variables to be accessed early.
This is needed for the return stack depth tracking retbleed mitigation
that will be in 6.2, but it also makes it possible to tighten the IBRS
restore on vmexit. The latter change is a long tail of the
spectrev2/retbleed patches (the corresponding Intel change was simpler
and went in already last June), which is why I am including it right
now instead of sharing a topic branch with tip.
Being assembly and being rich in comments makes the line count balloon
a bit, but I am pretty confident in the change (famous last words)
because the reorganization actually makes everything simpler and more
understandable than before. It has also had external review and has
been tested on the aforementioned 6.2 changes, which explode quite
brutally without the fix.
Apart from this, things are pretty normal.

io_uring/poll: lockdep annote io_poll_req_insert_locked

io_uring/poll: fix double poll req->flags races
io_poll_double_prepare() | io_poll_wake()
| poll->head = NULL
smp_load(&poll->head); /* NULL */ |
flags = req->flags; |
| req->flags &= ~SINGLE_POLL;
req->flags = flags | DOUBLE_POLL |
The idea behind io_poll_double_prepare() is to serialise with the
first poll entry by taking the wq lock. However, it's not safe to assume
that io_poll_wake() is not running when we can't grab the lock and so we
may race modifying req->flags.
Skip double poll setup if that happens. It's ok because the first poll
entry will only be removed when it's definitely completing, e.g.
pollfree or oneshot with a valid mask.

MIPS: pic32: treat port as signed integer
get_port_from_cmdline() returns an int, yet is assigned to a char, which is wrong in its own right, but also, with char becoming unsigned, this poses problems, because -1 is used as an error value. Further complicating things, fw_init_early_console() is only ever called with a -1 argument. Fix this up by removing the unused argument from fw_init_early_console() and treating port as a proper signed integer. Cc: Thomas Bogendoerfer <tsbogend@alpha.franken.de> Signed-off-by: Jason A.

MIPS: fix duplicate definitions for exported symbols
Building with clang-14 fails with:
AS arch/mips/kernel/relocate_kernel.o
<unknown>:0: error: symbol 'kexec_args' is already defined
<unknown>:0: error: symbol 'secondary_kexec_args' is already defined
<unknown>:0: error: symbol 'kexec_start_address' is already defined
<unknown>:0: error: symbol 'kexec_indirection_page' is already defined
<unknown>:0: error: symbol 'relocate_new_kernel_size' is already defined
It turns out EXPORT defined in asm/asm.h expands to a symbol definition,
so there is no need to define these symbols again. Remove duplicated
symbol definitions.

KVM: x86/mmu: Block all page faults during kvm_zap_gfn_range()
When zapping a GFN range, pass 0 => ALL_ONES for the to-be-invalidated
range to effectively block all page faults while the zap is in-progress.
The invalidation helpers take a host virtual address, whereas zapping a
GFN obviously provides a guest physical address and with the wrong unit
of measurement (frame vs. byte).
Alternatively, KVM could walk all memslots to get the associated HVAs,
but thanks to SMM, that would require multiple lookups. And practically
speaking, kvm_zap_gfn_range() usage is quite rare and not a hot path,
e.g. MTRR and CR0.CD are almost guaranteed to be done only on vCPU0
during boot, and APICv inhibits are similarly infrequent operations.

ata: libata-transport: fix error handling in ata_tdev_add()

ata: libata-transport: fix double ata_host_put() in ata_tport_add()
In the error path in ata_tport_add(), when calling put_device(),
ata_tport_release() is called, it will put the refcount of 'ap->host'.
And then ata_host_put() is called again, the refcount is decreased
to 0, ata_host_release() is called, all ports are freed and set to
null.
When unbinding the device after failure, ata_host_stop() is called
to release the resources, it leads a null-ptr-deref(), because all
the ports all freed and null.
