ionic: use dev_consume_skb_any outside of napi
CWE ID: N/A
Base Score (CVSS): N/A
CVE: CVE-2024-42071
Descrizione: In the Linux kernel, a vulnerability has been resolved for the `ionic` module. Specifically, the `ionic` module uses `dev_consume_skb_any` outside of `napi_skb_cache_put`. To ensure correct behavior, we need to ensure that `napi_skb_cache_put` receives a budget of 0 when it’s called. This is being triggered by a configuration stress test and a loop that runs `ethtool/20545`. A bug report has been found in the `ethtool` process, highlighting a potential issue. It points out that `ionic_tx_clean()` calls `napi_skb_cache_put()` which in turn calls `napi_skb_cache_put()`. However, the bug notes that the `napi_skb_cache_put` call is preceded by a warning: `/* Zero budget indicate non-NAPI context called us, like netpoll */`. This suggests a potential issue where the `ionic` module is incorrectly handling the `napi_skb_cache_put` call, and the bug report indicates a potential issue related to the `netpoll` notification.
