The issue is about UDP checksums being computed as 0 instead of converting them to 0xFFFF when using a shared Linux bridge among multiple guest OSes. + +Hmm, let me break this down. So, the problem occurs with packets transmitted via an e1000 NIC in the guest and emulated hardware in QEMU. The key point is that when Hardware checksum offload is enabled in the guest's NIC configuration, it's causing this issue. + +From the RFC768 reference, I remember that a computed checksum of zero should be transmitted as 0xFFFF because all ones indicate no checksum was generated. So, QEMU isn't handling this conversion correctly, leading to incorrect UDP packets. + +Now, looking at the possible categories: network seems relevant here since it's about NIC and packet transmission. Other possibilities like 'mistranslation' or 'assembly' don't fit as well because it's more about network behavior than code translation or assembly issues. + +So, the issue is specifically with how QEMU handles UDP checksums in a networking context when using a shared bridge setup. +</think> + +network \ No newline at end of file |
