Dear Linux folks,
Using Linux 4.18-rc5+ with kmemleak enabled on a MSI B350M MORTAR (MS-7A37)
with an AMD Ryzen 3 2200G, the memory leak below is suspected.
```
$ sudo less /sys/kernel/debug/kmemleak
unreferenced object 0xffff894f8874a2b8 (size 8):
comm "systemd-udevd", pid 119, jiffies 4294893109 (age 908.348s)
hex dump (first 8 bytes):
34 01 05 00 00 00 00 00 4.......

That's really vague. Any chance for a reproducer or some other types of
hints as to what you feel the problem is here?

Unfortunately, not really. I have a SanDisk USB storage medium attached.

```
After ten or eleven minutes after boot, systemd-udevd gets triggered
and causes the kmemleak message.
```
[ 82.196740] calling fuse_init+0x0/0x1a6 [fuse] @ 4455

[ 677.532745] kmemleak: 3 new suspected memory leaks (see /sys/kernel/debug/kmemleak)
```
Please note, that there could be memory corruption issues [1] with AMD
Raven devices. But as I can reproduce the kmemleak messages, I thought
that this is unrelated and that you might have an idea.
Please tell me, if I can provide more information. Sorry for
forgetting to attach the Linux messages.
Kind regards,
Paul

I guess you just have to run your system also with kmemleak, and you will

There are probably better ways for doing this but you can use objdump
for example:
$ objdump -l --prefix-addresses -j .text --disassemble=xhci_mem_init drivers/usb/host/xhci-hcd.ko
then find the offset xhci_mem_init+0xcfa. It should show you the line
numbers as well if you have compiled your kernel with debug info. This
should be close to the line that allocated the memory that was leaked.

Paul, it possible that your xhci controller has several
supported protocol extended capabilities for usb 3 ports, each
with their own custom protocol speed ID table.
xhci driver assumes there is only one custome PSI table per roothub,
and we will end up allocating the second PSI table on top of the first,
leaking the first.
Could you boot with xhci dynamic debug enabled, and show dmesg after boot, add:
xhci_hcd.dyndbg=+p
to you kernel cmdline.
Or as an alternative, show output of:
sudo cat /sys/kernel/debug/usb/xhci/*/reg-ext-protocol*

It has eight ports. last four of them are USB 3.1 ports.
It has a very odd setup where each 3.1 port has their own
supported protocol capability with a custom PSI, but all the PSI's are similar,
telling the port only support a 5Gbps speed.
We leak all the custom PSI tables for USB 3.1 ports except the last,
these would be the EXTCAP_MANTISSA1 = 0x00050134, which is the same as
the hex dump of the unreferenced object you posted earlier (considering byte order):
hex dump (first 8 bytes):
34 01 05 00 00 00 00 00 4.......
I'm working on a patch for this

xhci driver assumed that xHC controllers have at most one custom
supported speed table (PSI) for all usb 3.x ports.
Memory was allocated for one PSI table under the xhci hub structure.
Turns out this is not the case, some controllers have a separate
"supported protocol capability" entry with a PSI table for each port.
This means each usb3 port can in theory support different custom speeds.
To solve this cache all supported protocol capabilities with their PSI
tables in an array, and add pointers to the xhci port structure so that
every port points to its capability entry in the array.
When creating the SuperSpeedPlus USB Device Capability BOS descriptor
for the xhci USB 3.1 roothub we for now will use only data from the
first USB 3.1 capable protocol capability entry in the array.
This could be improved later, this patch focuses resolving
the memory leak.

Is there a "max" number of port capabilities that can happen? Or this
this truely dynamic?

Nit, no need to set to NULL here :)

Almost truly dynamic, each capability points to the next, last points to 0
But we can't have more "supported protocol capabilities" than xHC ports.
(MaxPorts value in xHC HCSPARAMS1 register)

addr2line helps here. So does gdb (gdb vmlinux l *(xhci_mem_init+0xcfa))

Yes, revert it.
This looks very odd, after second resume, and losing power driver

message on second resume after reverting the patch?

Ok, I think I got it.
Patch doesn't set xhci->num_port_caps to 0 in xhci_mem_cleanup().
Adding new ports will fail when we reinitialize xhci manually, like in this
exynos case where xhci loses power in suspend/resume cycle.
I'll post a new version soon

xhci driver assumed that xHC controllers have at most one custom
supported speed table (PSI) for all usb 3.x ports.
Memory was allocated for one PSI table under the xhci hub structure.
Turns out this is not the case, some controllers have a separate
"supported protocol capability" entry with a PSI table for each port.
This means each usb3 roothub port can in theory support different custom
speeds.
To solve this, cache all supported protocol capabilities with their PSI
tables in an array, and add pointers to the xhci port structure so that
every port points to its capability entry in the array.
When creating the SuperSpeedPlus USB Device Capability BOS descriptor
for the xhci USB 3.1 roothub we for now will use only data from the
first USB 3.1 capable protocol capability entry in the array.
This could be improved later, this patch focuses resolving
the memory leak.

Changes since v1:
- Clear xhci->num_port_caps in xhci_mem_cleanup()
Otherwise we fail to add new ports and cause NULL pointer dereference at
manual xhci re-initialization. This can happen at resume if host lost power
during suspend.

Nice!
Should I revert the first and then apply this?

Since next-20200211, we have been observing a regression exiting suspend
on our Tegra124 Jetson TK1 board. Bisect is pointing to this commit and
reverting on top of -next fixes the problem.
On exiting suspend, I am seeing the following ...
[ 56.216793] tegra-xusb 70090000.usb: Firmware already loaded, Falcon state 0x20
[ 56.216834] usb usb3: root hub lost power or was reset
[ 56.216837] usb usb4: root hub lost power or was reset
[ 56.217760] tegra-xusb 70090000.usb: No ports on the roothubs?
[ 56.218257] tegra-xusb 70090000.usb: failed to resume XHCI: -12
[ 56.218299] PM: dpm_run_callback(): platform_pm_resume+0x0/0x40 returns -12
[ 56.218312] PM: Device 70090000.usb failed to resume: error -12
[ 56.334366] hub 4-0:1.0: hub_ext_port_status failed (err = -32)
[ 56.334368] hub 3-0:1.0: hub_ext_port_status failed (err = -32)
Let me know if you have any thoughts on this.
Cheers
Jon

This was an issue with the first version, and should be fixed in the second.
next-20200211 has the faulty version,
next-20200213 is fixed, reverted first version and applied second.
Does next-20200213 work for you?
