firewire-ohci: device rediscovery hardlock regression

by Edmund Raile

Hello, I'd like to report a regression in firewire-ohci that results in the kernel hardlocking when re-discovering a FireWire device. TI XIO2213B RME FireFace 800 It will occur under three conditions: * power-cycling the FireWire device * un- and re-plugging the FireWire device * suspending and then waking the PC Often it would also occur directly on boot in QEMU but I have not yet observed this specific behavior on bare metal. Here is an excerpt from the stack trace (don't know whether it is acceptable to send in full): kernel: ------------[ cut here ]------------ kernel: refcount_t: addition on 0; use-after-free. kernel: WARNING: CPU: 3 PID: 116 at lib/refcount.c:25 refcount_warn_saturate (/build/linux/lib/refcount.c:25 (discriminator 1)) kernel: Workqueue: firewire_ohci bus_reset_work kernel: RIP: 0010:refcount_warn_saturate (/build/linux/lib/refcount.c:25 (discriminator 1)) kernel: Call Trace: kernel: <TASK> kernel: ? refcount_warn_saturate (/build/linux/lib/refcount.c:25 (discriminator 1)) kernel: ? __warn.cold (/build/linux/kernel/panic.c:693) kernel: ? refcount_warn_saturate (/build/linux/lib/refcount.c:25 (discriminator 1)) kernel: ? report_bug (/build/linux/lib/bug.c:180 /build/linux/lib/bug.c:219) kernel: ? handle_bug (/build/linux/arch/x86/kernel/traps.c:218) kernel: ? exc_invalid_op (/build/linux/arch/x86/kernel/traps.c:260 (discriminator 1)) kernel: ? asm_exc_invalid_op (/build/linux/./arch/x86/include/asm/idtentry.h:621) kernel: ? refcount_warn_saturate (/build/linux/lib/refcount.c:25 (discriminator 1)) kernel: for_each_fw_node (/build/linux/./include/linux/refcount.h:190 /build/linux/./include/linux/refcount.h:241 /build/linux/./include/linux/refcount.h:258 /build/linux/drivers/firewire/core.h:199 /build/linux/drivers/firewire/core-topology.c:275) kernel: ? __pfx_report_found_node (/build/linux/drivers/firewire/core- topology.c:312) kernel: fw_core_handle_bus_reset (/build/linux/drivers/firewire/core- topology.c:399 (discriminator 1) /build/linux/drivers/firewire/core- topology.c:504 (discriminator 1)) kernel: bus_reset_work (/build/linux/drivers/firewire/ohci.c:2121) kernel: process_one_work (/build/linux/./arch/x86/include/asm/jump_label.h:27 /build/linux/./include/linux/jump_label.h:207 /build/linux/./include/trace/events/workqueue.h:110 /build/linux/kernel/workqueue.c:3236) kernel: worker_thread (/build/linux/kernel/workqueue.c:3306 (discriminator 2) /build/linux/kernel/workqueue.c:3393 (discriminator 2)) kernel: ? __pfx_worker_thread (/build/linux/kernel/workqueue.c:3339) kernel: kthread (/build/linux/kernel/kthread.c:389) kernel: ? __pfx_kthread (/build/linux/kernel/kthread.c:342) kernel: ret_from_fork (/build/linux/arch/x86/kernel/process.c:153) kernel: ? __pfx_kthread (/build/linux/kernel/kthread.c:342) kernel: ret_from_fork_asm (/build/linux/arch/x86/entry/entry_64.S:254) kernel: </TASK> I have identified the commit via bisection: 24b7f8e5cd656196a13077e160aec45ad89b58d9 firewire: core: use helper functions for self ID sequence It was part of the following patch series: firewire: add tracepoints events for self ID sequence https://lore.kernel.org/all/20240605235155.116468-6-o-takashi@sakamocchi.jp/ #regzbot introduced: 24b7f8e5cd65 Since this was before v6.10-rc5 and stable 6.10.14 is EOL, stable v6.11.5 and mainline are affected. Reversion appears to be non-trivial as it is part of a patch series, other files have been altered as well and other commits build on top of it.

After a hard 3 hour look traversing all used functions and comparing against the original function (as of e404cacfc5ed), this caught my eye: for (port_index = 0; port_index < total_port_count; ++port_index) { switch (port_status) { case PHY_PACKET_SELF_ID_PORT_STATUS_PARENT: node->color = i; In both for loops, "port_index" was replaced by "i" "i" remains in use above: for (i = 0, h = &stack; i < child_port_count; i++) h = h->prev; While the original also used the less descriptive i in the loop for (i = 0; i < port_count; i++) { switch (get_port_type(sid, i)) { case SELFID_PORT_PARENT: node->color = i; but reset it to 0 at the beginning of the loop. So the stray "i" in the for loop should be replaced with the loop iterator "port_index" as it is meant to be synchronous with the loop iterator (i.e. the port_index), no? diff --git a/drivers/firewire/core-topology.c b/drivers/firewire/core- topology.c index 8c10f47cc8fc..7fd91ba9c9c4 100644 --- a/drivers/firewire/core-topology.c +++ b/drivers/firewire/core-topology.c @@ -207,7 +207,7 @@ static struct fw_node *build_tree(struct fw_card *card, const u32 *sid, int self // the node->ports array where the parent node should be.

Please tell me, is this line of reasoning correct or am I missing something? Compiling 24b7f8e5cd65 and later mainline with the patch above resulted in a kernel that didn't crash! In case my solution should turn out to be correct, I will gladly submit the patch. Kind regards, Edmund Raile.

[PATCH v10 0/6] RISC-V: Detect and report speed of unaligned vector accesses

by Charlie Jenkins

Adds support for detecting and reporting the speed of unaligned vector accesses on RISC-V CPUs. Adds vec_misaligned_speed key to the hwprobe adds Zicclsm to cpufeature and fixes the check for scalar unaligned emulated all CPUs. The vec_misaligned_speed key keeps the same format as the scalar unaligned access speed key. This set does not emulate unaligned vector accesses on CPUs that do not support them. Only reports if userspace can run them and speed of unaligned vector accesses if supported.

[PATCH] iio: light: veml6030: fix microlux value calculation

by Javier Carrasco

The raw value conversion to obtain a measurement in lux as INT_PLUS_MICRO does not calculate the decimal part properly to display it as micro (in this case microlux). It only calculates the module to obtain the decimal part from a resolution that is 10000 times the provided in the datasheet (0.5376 lux/cnt for the veml6030). The resulting value must still be multiplied by 100 to make it micro. This bug was introduced with the original implementation of the driver. Cc: stable(a)vger.kernel.org Fixes: 7b779f573c48 ("iio: light: add driver for veml6030 ambient light sensor") Signed-off-by: Javier Carrasco <javier.carrasco.cruz(a)gmail.com> --- I found this almost by chance while testing new supported devices. The decimal part was always suspiciously small, and when I compared samples to the expected value according to the datasheet, it became clear what was going on. Example with a veml7700 (same resolution as the veml6030): Resolution for gain = 1/8, IT = 100 ms: 0.5736 lux/cnt. cat in_illuminance_raw in_illuminance_input 40 21.005040 -> wrong! 40 * 0.5736 is 21.504.
