USB: serial: io_ti: reject oversized boot-mode firmware
do_boot_mode() copies the firmware payload, excluding its four-byte prefix,
into a fixed 15.5 KiB staging buffer. check_fw_sanity() already proves that
the image contains its seven-byte header and validates the declared image
length and checksum, but it does not impose this boot-mode destination
limit.
Reject images whose payload does not fit before allocating and filling the
staging buffer.

USB: serial: mxuport: validate firmware header size
mxuport_probe() reads version bytes at fixed offsets after
request_firmware() succeeds. Firmware loading success does not prove that
the blob reaches the highest version offset.
Reject short firmware images before reading the version bytes. This is
source-level parser hardening; no affected device or crash was observed.

USB: serial: keyspan_pda: fix data loss on receive throttling
Killing the interrupt-in urb when the line disciple requests throttling
may lead to data loss if an ongoing transfer is cancelled.
Instead set a flag to prevent the completion handler from resubmitting
the urb until the port is unthrottled.

tpm: Make the TPM character devices non-seekable
The TPM character devices expose a sequential command/response
interface, but their open handlers leave FMODE_PREAD and FMODE_PWRITE
enabled.
After a command leaves a response pending, pread(fd, buf, 16, 0x1400)
passes 0x1400 as *off to tpm_common_read(). The transfer length is
bounded by response_length, but the offset is used unchecked when
forming data_buffer + *off. A sufficiently large offset therefore causes
an out-of-bounds heap read through copy_to_user() and, if the copy
succeeds, an out-of-bounds zero-write through the following memset().
Positional I/O does not provide coherent semantics for this interface.
An arbitrary pread offset cannot represent how much of a response has
been consumed sequentially. The write callback always stores a command
at the start of data_buffer, while pwrite() does not update file->f_pos
and can leave the sequential read cursor stale.
Call nonseekable_open() from both open handlers. This removes
FMODE_PREAD and FMODE_PWRITE, causing positional reads and writes to
fail with -ESPIPE before reaching the TPM callbacks, and explicitly
marks the files non-seekable. Normal read() and write() continue to use
the existing sequential f_pos cursor, leaving the response state machine
unchanged.
Tested on Linux 6.12 with KASAN and a swtpm TPM2 device:
- sequential partial reads returned the complete response
- pread() and preadv() with offset 0x1400 returned -ESPIPE
- pwrite() and pwritev() with offset zero returned -ESPIPE
- the pending response remained intact after the rejected operations
- a subsequent normal command/response cycle completed normally
- no KASAN report was produced.

- Free field in error path of synthetic event parse In __create_synth_event() the field was allocated but was not freed in the error path. - Fix ring_buffer_event_length() on 8 byte aligned architectures On architectures with CONFIG_HAVE_64BIT_ALIGNED_ACCESS set to y, the ring_buffer_event_length() may return the wrong size. This is because archs with that config set will always use the "big event meta header" as that is 8 bytes keeping the payload 8 bytes aligned, even when a 4 byte header could hold the size of the event. But ring_buffer_event_length() doesn't take this into account and only subtracts 4 bytes for the meta header in the length when it should have subtracted 8 bytes. - Have osnoise wait for a full rcu synchronization on unregister osnoise_unregister_instance() used to call synchronize_rcu() before freeing its copy of the instance but was switched to kfree_rcu(). The osniose tracer has code that traverses the instances that it uses, and inst is just a pointer to that instance. By using kfree_rcu() instead of synchronize_rcu(), the instance that the inst pointer is pointing to can be freed while the osnoise code is still referencing it. That is, a rmdir on an instance first unregisters the tracer. When the unregister finishes, the rmdir expects that the tracer is finished with the instance that it is using. By putting back the synchronize_rcu() in osnoise_unregister_instance() the unregistering of osnoise will now return when all the users of the instance have finished. - Remove an unused setting of "ret" in tracing_set_tracer() - Fix ring_buffer_read_page() copying events The commit that changed ring_buffer_read_page() to show dropped events from the buffer itself, split the "commit" variable between the commit value (with flags) and "size" that holds the size of the sub-buffer. A cut and paste error changed the test of the reading from checking the size of the buffer to the size of the event causing reads to only read one event at a time. - Make tracepoint_printk a static variable When the tracing sysctl knobs were move from sysctl.c to trace.c, the variable tracepoint_printk no longer needed to be global. Make it static. - Fix some typos - Fix NULL pointer dereference in func_set_flag() The flags update of the function tracer first checks if the value of the flag is the same and exits if they are, and then it checks if the current tracer is the function tracer and exits if it isn't. The problem is that these checks need to be in a reversed order, as if the tracer isn't the function tracer, then the flag being checked may not exist. Reverse the order of these checks. - Fix ufs core trace events to not dereference a pointer in TP_printk() The TP_printk() part of the TRACE_EVENT() macro is called when the user reads the "trace" file. This can be seconds, minutes, hours, days, weeks, and even months after the data was recorded into the ring buffer. Thus, saving a pointer to an object into the ring buffer and then dereferencing it from TP_printk() can cause harm as the object the pointer is pointing to may no longer exist. Fix all the trace events in ufs core to save the device name in the ring buffer instead of dereferencing the device descriptor from TP_printk(). - Prevent out-of-bound reads in glob matching of trace events The filter logic of events allows simple glob logic to add wild cards to filter on strings. But some events have fields that may not have a terminating 'nul' character. This may cause the glob matching to go beyond the string. Change the logic to always pass in the length of the field that is being matched. - Add no-rcu-check version of trace_##event##_enabled() The trace_##event##_enabled() usually wraps trace events to do extra work that is only needed when the trace event is enabled. But this can hide events that are placed in locations where RCU is not watching, and can make lockdep not see these bugs when the event is not enabled. The trace_##event##_enabled() was updated to always test to make sure RCU is watching to catch locations that may call events without RCU being active. This caused a false positive for the irq_disabled() and related events. As that use trace_irq_disabled_enabled() to force RCU to be watching when the event is enabled via the ct_irq_enter() function, calls the event, and then calls ct_irq_exit() to put RCU back to its original state. The trace_irq_disabled_enabled() should not trigger a warning when RCU is not watching because the code within its block handles the case properly. Make a __trace_##event##_enabled() version for this event to use that doesn't check RCU is watching as it handles the case when it isn't. - Fix use-after-free in user_event_mm_dup() When the enabler is removed from the link list, it is freed immediately. But it is protected via RCU and needs to be freed after an RCU grace period. Use queue_rcu_work() so that the event_mutex can also be taken as user_event_put() takes the mutex on the last reference is released. - Free type string in error path of parse_synth_field() There's an error path in parse_synth_field() where the allocated type string is not freed. - Add selftest that tests deferred event teardown - Fix leak in error path of trace_remote_alloc_buffer() If page allocation fails, the desc->nr_cpus is not incremented for the current CPU and the allocations done for it are not freed. - Fix allocation length in trace_remote_alloc_buffer() The logic to calculate the struct_len was doing a double count and setting the value too large. Calculate the size upfront to fix the error and simplify the logic. - Fix sparse CPU masks in ring_buffer_desc() If there are sparse CPUs (gaps in the numbering), the ring_buffer_desc() will fail as it tests the CPU number against the number of CPUs that are used. -----BEGIN PGP SIGNATURE----- iQJIBAABCgAyFiEEXtmkj8VMCiLR0IBM68Js21pW3nMFAmpTv/cUHHJvc3RlZHRA Z29vZG1pcy5vcmcACgkQ68Js21pW3nN80w/9HEbliUUrJVNw8QCY8BmeBEzfCRhZ 2CeDzTg+UrLMb2BtqUhA9EjQnRPawe8mPxAfpZ750SdFnCkRhbfNwYmKar3M/8iW y2Bhsvd3Hz6nRiHvKhG/1RkflgKOWLYf/TQSByKlakYLV8t4uffa0fe0N0zcnikK XPGrhrTeRDJ7s94vb1u7p7mSSp2iy4ZhfXbagk966X3I4zvseIYNn5IIzyM3IIPT M7mE60SxvgSRz0QqTJqihmqjXYSeNOQ2iU18wnvp4QfcT0IVuLKm027JnK/YpjWS ZasMNGzO1kp5uo6hkXLrMlT3LjaNEMFTGogs1m9o9auhbMf443LK8GtZ1m1rwnTG cXn1PocBevQIaXWPbnxMrSwIuN7YMUqjgX6SCxbXpDxSSuE5i/x1VmE08CjxnSm6 TdAdom9bE44FvMgaAz9+KhIUgm013c2rFDNiFroYtfkma5FqpfnfglA4/TkJvexY e2L75cR3lrDEDiXXMQDndmvxNMhppwNlAH3mOZLiaCmGyFQFHhgAaG250K2Y6a5K HtIfJkT6RQ3rWifV0E0+zlyRiOrvVCCA8WwNArWb1dTWrVU86Hr7q58jAq9p0Yrz FnhpjdE3eWoUHZ5f28AMR2k5lMG3o6mOGT55JyUVCLw+rPSG5358UIg2xZiEo22k RFlT26FFHbMW50Y= =+//w -----END PGP SIGNATURE----- Merge tag 'trace-v7.2-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing fixes from Steven Rostedt: - Free field in error path of synthetic event parse In __create_synth_event() the field was allocated but was not freed in the error path - Fix ring_buffer_event_length() on 8 byte aligned architectures On architectures with CONFIG_HAVE_64BIT_ALIGNED_ACCESS set to y, the ring_buffer_event_length() may return the wrong size.

dm thin metadata: fix superblock refcount leak on snapshot shadow failure
__reserve_metadata_snap() increments THIN_SUPERBLOCK_LOCATION in the
metadata space map before shadowing it. When dm_tm_shadow_block()
fails, a reference is leaked in the metadata space map.
Fix by adding the missing dm_sm_dec_block().

perf/x86/amd/brs: Fix kernel address leakage
A user-only branch stack can contain branches that originate from
the kernel. As a result, kernel addresses are exposed to user space
even when PERF_SAMPLE_BRANCH_USER is requested. On AMD processors
supporting X86_FEATURE_BRS (Zen 3 only), perf can still report entries
such as SYSRET/interrupt returns for which the branch-from addresses
are in the kernel.
E.g.
$ perf record -j any,u -c 4000 -e branch-brs -o - -- \
perf bench syscall basic --loop 1000 | \
perf script -i - -F brstack|tr ' ' '\n'| \
grep -E '0x[89a-f][0-9a-f]{15}'
...
0xffffffff810001c4/0x72e2e32955eb/-/-/-/0//-
0xffffffff810001c4/0x72e2d94a9821/-/-/-/0//-
0xffffffff810001c4/0x72e2d94ffa1b/-/-/-/0//-
...
BRS provides no hardware branch filtering, so privilege level
filtering is performed entirely in software. However, amd_brs_match_plm()
only validates the branch-to address against the requested privilege
levels. For branches from the kernel to user space, the branch-from
address is left unchecked and is leaked. Extend the software filter to
also validate the branch-from address, so that any branch record whose
branch-from address is in the kernel is dropped when
PERF_SAMPLE_BRANCH_USER is requested.

Input: mms114 - fix multi-touch slot corruption
If the touchscreen controller reports a touch ID of 0, the driver
calculates the slot ID as touch->id - 1, which underflows to UINT_MAX.
This is passed to input_mt_slot() as -1.
Since the input core ignores negative slot values, the active slot remains
unchanged. The driver then reports the touch coordinates for the previously
active slot, corrupting its state.
Fix this by rejecting touch reports with ID 0.

dm-bufio: fix wrong count calculation in dm_bufio_issue_discard
block_to_sector converts a block number to a sector number and adds
c->start to the result. It is inappropriate to use this function for
converting the number of blocks to a number to sectors because c->start
would be incorrectly added to the result.
Luckily, the only target that uses dm_bufio_issue_discard is dm-ebs,
which sets c->start to 0, so this bug is latent.

block: remove redundant GD_NEED_PART_SCAN in add_disk_final()
add_disk_final() sets GD_NEED_PART_SCAN before calling bdev_add(), then calls disk_scan_partitions() which sets the flag itself. The early set is redundant and introduces a race. Between bdev_add() and disk_scan_partitions(), concurrent openers (multipathd, blkid, LVM) see the flag in blkdev_get_whole() and trigger bdev_disk_changed(). When disk_scan_partitions() then runs, it calls bdev_disk_changed() again, dropping the partitions the concurrent opener already created before re-adding them, which can result in transient partition disappearances. The race is observable by inserting an msleep() between bdev_add() and disk_scan_partitions() while running concurrent open() calls during device bind. Without artificial delay, it manifests under scheduling pressure during boot on systems with aggressive device scanners (multipathd, systemd-udevd). Therefore, do not set GD_NEED_PART_SCAN in add_disk_final(). Other GD_NEED_PART_SCAN consumers (blkdev_get_whole(), sd_need_revalidate()) should not be affected as the flag is set internally by disk_scan_partitions().

perf/x86/amd/lbr: Fix kernel address leakage
A user-only branch stack can contain branches that originate from
the kernel. As a result, kernel addresses are exposed to user space
even when PERF_SAMPLE_BRANCH_USER is requested. On AMD processors
supporting X86_FEATURE_AMD_LBR_V2, perf can still report SYSRET/ERET
entries for which the branch-from addresses are in the kernel.
E.g.
$ perf record -e cycles -o - -j any,save_type,u -- \
perf bench syscall basic --loop 1000 | \
perf script -i - -F brstack|tr ' ' '\n'| \
grep -E '0x[89a-f][0-9a-f]{15}'
...

0xffffffff81001268/0x717a90a39157/M/-/-/0/ERET/NON_SPEC_CORRECT_PATH
0xffffffff81001268/0x717a90a2c628/M/-/-/0/ERET/NON_SPEC_CORRECT_PATH
0xffffffff81001268/0x717a90a41b60/M/-/-/0/ERET/NON_SPEC_CORRECT_PATH
0xffffffff81001268/0x717a90a260db/M/-/-/0/ERET/NON_SPEC_CORRECT_PATH
0xffffffff81001268/0x717a90a260db/M/-/-/0/ERET/NON_SPEC_CORRECT_PATH

0xffffffff81001268/0x717a8e4d3c90/M/-/-/0/ERET/NON_SPEC_CORRECT_PATH
...
The reason is that the hardware filter only considers the privilege
level applicable to the branch target. Extend software filtering to
also validate the branch-from addresses against br_sel, so that any
branch record whose branch-from address is in the kernel is dropped
when PERF_SAMPLE_BRANCH_USER is requested.

drbd: reject data replies with an out-of-range payload size
recv_dless_read() receives a P_DATA_REPLY from a peer into the bio of an
outstanding read request. The peer-supplied payload length reaches it as
the signed int data_size, and two peer-controlled inputs can make it
negative. With a negotiated data-integrity-alg the digest length is
subtracted first, so a reply whose payload is smaller than the digest
underflows data_size. With no integrity algorithm (the default) data_size
is assigned from the unsigned h95/h100 wire length and drbdd() never
bounds it for a payload-carrying command, so a length above INT_MAX casts
it negative; this path needs no non-default feature. The bio receive loop
then computes expect = min_t(int, data_size, bv_len), which is negative,
and drbd_recv_all_warn(mapped, expect) receives with a size_t of SIZE_MAX
into the first mapped page.
The sibling receive path read_in_block() is not affected: it uses an
unsigned size and rejects it against DRBD_MAX_BIO_SIZE before receiving.
Reject a data reply whose size is negative after the optional digest
subtraction, covering both triggers.
Impact: a malicious or man-in-the-middle DRBD peer copies attacker-chosen
bytes past a bio page in the receiver, corrupting kernel memory. A node
that reads from its peer (a diskless node, or read-balancing to the peer)
is exposed in the default configuration; data-integrity-alg is not
required.

serial: 8250: Ignore flow control on suspend/resume with no_console_suspend
If no_console_suspend is specified, on suspend the 8250 console driver uses a scratch register (UART_SCR) to store a special canary value. This is used during the resume path to identify a printk() call before the driver's own ->resume() callback. In this case, serial8250_console_restore() is called to quickly re-init the 8250 for console printing. See commit |

serial: 8250_omap: clear rx_running on zero-length DMA completes
On AM33xx RX DMA only triggers when the FIFO reaches the
configured threshold (typically 48 bytes). For smaller bursts
no DMA request is issued and the FIFO is drained by RX timeout.
In this case __dma_rx_do_complete() can legitimately see count == 0.
The current code exits early in this case and does not clear
dma->rx_running, leaving the DMA state inconsistent. This can
prevent RX DMA from restarting and may cause
omap_8250_rx_dma_flush() to fail, marking DMA as broken.
Fix this by clearing dma->rx_running once the DMA transfer has
completed or been terminated, even if no data was transferred.

vt: fix spurious modifier in CSI/cursor key sequences
csi_modifier_param() builds the xterm modifier parameter from
shift_state, counting KG_SHIFTL/KG_SHIFTR as Shift, KG_ALTGR as Alt
and KG_CTRLL/KG_CTRLR as Ctrl in addition to the canonical KG_SHIFT,
KG_ALT and KG_CTRL.
That is wrong when those weights are not plain modifiers. Keymaps
derived from XKB layouts (by kbd's xkbsupport, and by the
console-setup used in Debian, Ubuntu and others) encode the active
layout group using KG_SHIFTL/KG_SHIFTR:
group 1: -
group 2: shiftl
group 3: shiftr
group 4: shiftl | shiftr
So while a non-default layout group is selected, KG_SHIFTL and/or
KG_SHIFTR are set in shift_state with no Shift key held.
csi_modifier_param() then adds a spurious Shift to every cursor and
CSI key: pressing Up while group 2 is active emits ESC[1;2A (Shift+Up)
instead of ESC[A. KG_ALTGR has the same problem since it is the
standard third-level selector.
Normal keymaps bind the physical Shift/Ctrl/Alt keys to KG_SHIFT,
KG_CTRL and KG_ALT, leaving the left/right and AltGr weights free for
layout and level selection. Count only those canonical weights, so
genuine modifiers are still encoded while layout/level selectors are
not.
