[SRU][F][PATCH 0/1] CVE-2024-35958

[Tim Whisonant]

[Impact]

net: ena: Fix incorrect descriptor free behavior

Adding a check for XDP traffic in ena_free_tx_bufs() so that XDP buffers
are not errantly sent to napi_consume_skb(). This prevents a bug related
to VF reset, which resulted in a system crash.

[Cherry Pick]

Cherry picked from commit bf02d9fe00632d22fa91d34749c7aacf397b6cde

[Fix]

Oracular:   Not affected
Noble:      Fixed upstream
Jammy:      Fixed upstream
Focal:      Cherry picked from linux-6.9
Bionic:     Not affected
Xenial:     Not affected
Trusty:     Not affected

[Test Plan]

Compile and boot tested only.

[Where problems could occur]

The change is isolated to the Elastic Network Adapater driver,
specifically the TX queue logic.
