[Bug 2055296] Re: qemu: virtio: bogus descriptor or out of resources
Hello Paride, the implication is only possibly increased memory usage. But the patch may not cover all cases were this error might arise. I agree that we should watch the upstream discussion in https://lore.kernel.org/qemu- devel/20240228125939.56925-1-heinrich.schucha...@canonical.com/T/#u and see how this settles.

[Bug 2055296] Re: qemu: virtio: bogus descriptor or out of resources
Hi Heinrich, While the patch itself is small, it's not straightforward to tell what the implications of -l = MIN(l, TARGET_PAGE_SIZE); +l = MIN(l, 0x1); are. Also: looks like the patch has not been applied upstream yet, and there's some active discussion about it in the qemu-devel mailing list. Given that AIUI a very specific configuration is required to trigger this bug, I think we should delay adding it as an Ubuntu delta at least until accepted upstream. Would you find this a sensible approach?
