Public bug reported:
Hello,
Using hypervisor fuzzer, hyfuzz, I found an assertion failure through
usb-ehci.
This was found in version 5.0.1 (stable-5.0).
--------
qemu-system-i386: src/qemu-repro/exec.c:3581: address_space_unmap: Assertion `mr != NULL' failed.
[1] 14721 abort src/qemu-repro/build/i386-softmmu/qemu-system-i386
To reproduce the assertion failure, please run the QEMU with following command line.
```
$ qemu-system-i386 -drive file=./hyfuzz.img,index=0,media=disk,format=raw -m 512 -drive if=none,id=stick,file=./usbdisk.img -device usb-ehci,id=ehci -device usb-storage,bus=ehci.0,drive=stick
```

Can you still reproduce this with QEMU v6.0 ? For me, qemu now does not
crash anymore, so I assume this might have been fixed within the past
months?

This problem got fixed by this commit:
2fdb42d840400d58f2e706ecca82c142b97bcbd6
hw: ehci: check return value of 'usb_packet_map'
Thus let's close this ticket now.
