2 daysdrm/gud: validate GUD_ROTATION_0 is present in supported rotationsSajal Gupta
The rotation argument to drm_plane_create_rotation_property() is set to DRM_MODE_ROTATE_0, and the device reported rotation bitmask is used as the supported_rotations argument. The driver never validates that GUD_ROTATION_0 is present, so a device that omits it from its GUD_PROPERTY_ROTATION triggers the WARN_ON(rotation & ~supported_rotations) in drm_plane_create_rotation_property() Fix this by skipping the creation of rotation property if the device doesn't have the GUD_ROTATION_0 bit Fixes: 40e1a70b4aed ("drm: Add GUD USB Display driver") Reported-by: syzbot+efe2810681f1b065d3a8@syzkaller.appspotmail.com Closes: https://syzkaller.appspot.com/bug?extid=efe2810681f1b065d3a8 Tested-by: syzbot+efe2810681f1b065d3a8@syzkaller.appspotmail.com Signed-off-by: Sajal Gupta <sajal2005gupta@gmail.com> Acked-by: Ruben Wauters <rubenru09@aol.com> Signed-off-by: Ruben Wauters <rubenru09@aol.com> Link: https://patch.msgid.link/20260821071812.16500-1-sajal2005gupta@gmail.com

2 daysdrm/gud: validate TV mode names before creating enum propertyTao Yu
The GUD protocol returns TV mode names as fixed-size GUD_CONNECTOR_TV_MODE_NAME_LEN entries and requires each name to be NUL-terminated. gud_connector_add_tv_mode() currently passes each fixed-size entry directly to drm_mode_create_tv_properties_legacy(), which eventually reaches drm_property_add_enum() and strlen(). If a device returns an entry without a terminating NUL byte, strlen() reads past the end of the slot and can run beyond the allocated buffer, triggering an out-of-bounds read. Validate that each returned TV mode name contains a NUL terminator within its fixed-size slot before passing it to the DRM property code. If a malformed entry is found, reject the device response with -EIO. This fixes the out-of-bounds read without changing the handling of valid devices, and avoids silently truncating malformed protocol data.

2 daysdrm/gud: NUL-terminate TV mode names read from the deviceDeepanshu Kartikey
gud_connector_add_tv_mode() reads a buffer of fixed-size mode names from the USB device and passes pointers into it to drm_mode_create_tv_properties_legacy(), which calls strlen() on each one. Nothing guarantees the device NUL-terminates a name, so strlen() can run past the end of a slot and, for the last mode, past the end of the allocation. Terminate each name at the end of its slot before use.

2 dayshwmon: (sht4x) Fix return value from heater_enable_store()Guenter Roeck
Sashiko reports: The return value in heater_enable_store() causes an unexpected write failure in user-space. When the heater is successfully enabled, the function returns 0 instead of count: drivers/hwmon/sht4x.c:heater_enable_store() { ... data->heating_complete = jiffies + msecs_to_jiffies(heating_time_bound); data->data_pending = true; return 0; } Returning 0 signals to VFS that no bytes were processed. Standard user-space tools will retry the write with the remaining bytes. On the retry, time_before(jiffies, data->heating_complete) evaluates to true, and the function immediately fails with -EBUSY. Return count as expected to fix the problem.

2 dayshwmon: (ina2xx) Decouple in0 and curr1 alarmsJared Kangas
INA2XX current limits are converted into shunt voltage limits internally using the shunt resistor value. Once a current limit's corresponding voltage limit is written to the hardware, shunt voltage and current alarms are indistinguishable from each other. This causes two issues: 1. in0/curr1 alarms may be unintentionally cleared by reading from the opposite input's alarm. 2. When a limit for either in0 (shunt voltage) or curr1 (current) is set, both of their alarms are triggered, and both of their limits read nonzero. An example of this behavior on an INA231: # cd /sys/class/hwmon/hwmon0 # head {curr1,in0}_input ==> curr1_input <== 1713 ==> in0_input <== 2 # echo 1800 >curr1_lcrit # head {curr1,in0}_lcrit_alarm ==> curr1_lcrit_alarm <== 1 ==> in0_lcrit_alarm <== 0 # head {in0,curr1}_lcrit_alarm ==> in0_lcrit_alarm <== 1 ==> curr1_lcrit_alarm <== 0 # head {in0,curr1}_lcrit_alarm ==> in0_lcrit_alarm <== 1 ==> curr1_lcrit_alarm <== 1 This is because curr1 uses the same underlying masks (INA226_SHUNT_*_VOLTAGE_MASK) as in0 on the hardware. As a result, ina2xx_{curr,in}_read() both read the shunt voltage alarms/limits without considering whether the voltage or current is currently set. To fix this, track the active alarm type in ina2xx_data and guard alarm/limit reads with a check that returns zero if the active alarm is for a different type. The new field is initialized based on the MASK_ENABLE register's set function, assuming voltage instead of current when the shunt voltage mask is set. After this fix, the alarms only read back 1 if their corresponding limit is set: # echo 0 >curr1_lcrit # head {curr1,in0}_lcrit_alarm ==> curr1_lcrit_alarm <== 0 ==> in0_lcrit_alarm <== 0 # echo 9999 >curr1_lcrit # head {curr1,in0}_lcrit_alarm ==> curr1_lcrit_alarm <== 1 ==> in0_lcrit_alarm <== 0 # echo 9999 >in0_lcrit # head {curr1,in0}_lcrit_alarm ==> curr1_lcrit_alarm <== 0 ==> in0_lcrit_alarm <== 1 Fixes: 4d5c2d986757 ("hwmon: (ina2xx) Add support for current limits") Signed-off-by: Jared Kangas <jkangas@redhat.com> Link: https://patch.msgid.link/20260820-upstream-ina2xx-in0-curr1-alarms-v2-4-fdce35abc41e@redhat.com Signed-off-by: Guenter Roeck <linux@roeck-us.net>

3 daysiio: frequency: admv1013: fix wrong channel field used in admv1013_read_raw()Salah Triki
admv1013_read_raw() switches on chan->channel instead of chan->channel2 when handling IIO_CHAN_INFO_CALIBBIAS. The channel field only ever holds 0 or 1 (see ADMV1013_CHAN_CALIB()), while the IIO_MOD_I / IIO_MOD_Q modifiers are stored in channel2. As a result, the switch always falls through to the default case and calibbias reads always fail with -EINVAL, even though the corresponding admv1013_write_raw() path correctly uses channel2 and works as expected.

3 daysnet: libwx: fix concurrent bitmap overwrite in PTP setupJiawen Wu
In wx_ptp_set_timestamp_mode(), the driver copies the global `wx->flags` bitmap to a local variable, modifies the PTP-related bits, and then writes the entire bitmap back using memcpy(). This Read-Copy-Update pattern is unsafe and introduces a critical race condition. Other asynchronous contexts (such as Tx timeout routines or GPIO IRQ handlers) update individual bits in `wx->flags` concurrently using atomic bitops like set_bit() or clear_bit(). The memcpy() write-back can silently overwrite and drop these concurrent changes, potentially causing the driver to miss critical module reset or PCIe recovery requests. Fix this by removing the local bitmap copy. Instead, evaluate the intended PTP flag states locally and apply them directly to `wx->flags` using atomic set_bit() and clear_bit() operations only after the hardware is successfully configured.

3 daysqede: Fix NULL pointer dereference in TPA fragment processingVaibhav Nagare
Under memory pressure, the qede driver encounters NULL pointer dereferences when processing TPA continuation fragments. Commit 8a8633978b84 ("qede: Add build_skb() support.") accidentally dropped the assignment of tpa_info->buffer.data in qede_tpa_start(). When memory pressure causes an SKB allocation failure in qede_tpa_start(), the driver sets tpa_start_fail = true and attempts to recycle the physical page later in qede_tpa_end() via qede_reuse_page(). However, because buffer.data was left uninitialized (NULL), qede_reuse_page() pushes a "ghost" BD (valid DMA mapping but NULL data pointer) back into the active Rx ring. The next time the hardware uses this ring slot, it passes a NULL page to qede_fill_frag_skb(), causing a kernel panic.

3 daysnet: txgbe: fix MISC interrupt unmasking in non-MSI-X mode and device shutdownJiawen Wu
In txgbe_misc_irq_thread_fn(), the driver unmasks the miscellaneous interrupt at the end of the handler using TXGBE_INTR_MISC(wx) (which resolves to BIT(wx->num_q_vectors)). While this is correct for MSI-X mode, it is incorrect for legacy INTx or single MSI modes. Due to hardware behavior, the WX_PX_MISC_IVAR register is completely ignored by the hardware when MSI-X is disabled. In non-MSI-X mode, the hardware forcibly merges all interrupt causes (both Queue and MISC) into a single bit: BIT(0) of the interrupt register. Unconditionally unmasking TXGBE_INTR_MISC(wx) (e.g., BIT(1)) in non-MSI-X mode means the actual MISC interrupt bit (BIT(0)) is not unmasked promptly at the end of the MISC thread. Instead, it remains masked until NAPI completes its polling and unmasks the shared BIT(0). This delays the assertion of subsequent MISC interrupts, preventing timely handling of events like link state changes. Fix this by explicitly checking `pdev->msix_enabled` and falling back to BIT(0) as the interrupt mask for the MISC cause when MSI-X is disabled. Additionally, unconditionally unmasking the interrupt at the end of the thread introduces a race condition during device teardown. Guarding the wx_intr_enable() call with a check for the WX_STATE_DOWN bit, to prevent re-arming the interrupt during device shutdown.

3 daysnet: microchip: vcap: use port number instead of netdev name for debugfsDaniel Machon
sparx5_vcap_init() runs before sparx5_register_netdevs() in probe, and its debugfs setup calls vcap_port_debugfs() for every port using netdev_name(ndev) as the debugfs file name. At that point the netdevs have only been allocated, not registered, so dev->name still holds the "eth%d" template and netdev_name() returns "(unnamed net_device)". Every port tries to create the same file under vcaps/, producing a flood of warnings at boot: debugfs: '(unnamed net_device)' already exists in 'vcaps' debugfs: '(unnamed net_device)' already exists in 'vcaps' ... Add vcap_port_debugfs_portno(), a variant of vcap_port_debugfs() that takes the port's stable hardware port number and uses "p%u" as the debugfs file name instead of netdev_name(ndev). This makes the file name independent of registration order; the file still stores and later dereferences the netdev itself, same as before. sparx5 already reports the same "p%d" string via ndo_get_phys_port_name(), so the debugfs name now matches that. Only sparx5 (and lan969x, which shares this code) is switched to the new function. lan966x keeps calling vcap_port_debugfs() unchanged, so this fix does not rename any of its existing debugfs files.

3 daysnet: ntb_netdev: Count packets dropped on RX refill failureKoichiro Den
When replacement skb allocation fails, ntb_netdev drops a packet that was received successfully and requeues the original buffer. The drop is counted, but rx_packets and rx_bytes are not. Count every good packet before allocating its replacement.

netif_rx() already accounts packets it drops in the core rx_dropped counter. ntb_netdev counts them again as both errors and drops. Leave netif_rx() drops to the core. Count the packet and bytes unconditionally since it was received successfully by the driver.

3 daysptp: netc: fix period truncation and potential divide-by-zero in PEROUTWei Fang
The max_period bound in net_timer_enable_perout() was computed as: max_period = (u64)NETC_TMR_DEFAULT_FIPER + integral_period; which exceeds U32_MAX when integral_period > 0 (e.g. 0x100000002 for the default 333333333 Hz clock). A period_ns that passes this check but exceeds U32_MAX is then silently truncated when stored into the u32 struct netc_pp::period field. A truncated value of zero can reach netc_timer_set_perout_alarm(), where the local u32 period variable would also be 0, causing a divide-by-zero in roundup_u64(delta, period) whenever the stime < min_time branch is taken (which always happens for a start time of {0, 0}). Additionally, netc_timer_enable_periodic_pulse() and netc_timer_enable_fiper() both compute: fiper = pp->period - integral_period; A zero pp->period results in an unsigned wraparound to 0xFFFFFFFD, mis-programming the FIPER hardware register. Fix all three issues by capping max_period at NETC_TMR_DEFAULT_FIPER (0xFFFFFFFF). This ensures that any period_ns passing the range check fits in a u32 without truncation, so the stored value is always valid and non-zero. The accepted range is reduced by integral_period ns (typically only a few nanoseconds), which is negligible in practice.

3 daysbnxt_en: Gate TPH enablement behind BNXT_SUPPORTS_QUEUE_API checkThomas Walsh
In bnxt_request_irq(), pcie_enable_tph() is called unconditionally to enable PCIe TPH when setting up interrupts. If the NIC hardware or firmware capabilities do not support queue ops, attempting to enable TPH during bnxt_request_irq() is unnecessary. As a result a flood of "RX queue restart failed: err=-95" messages is seen upon boot. Older NICs (pre-Thor / BCM57414) do not support TPH or queue management. TPH requires queue management to restart the queue. NICs that support queue management (with updated FW) all support TPH. Gate the call to pcie_enable_tph() and setting of bp->tph_mode behind BNXT_SUPPORTS_QUEUE_API(bp) to ensure TPH is only initialized on devices capable of supporting queue ops. This prevents a guaranteed -EOPNOTSUPP error from occurring due to NULL operations.
