[PATCH 5.16 062/164] net: __pskb_pull_tail() & pskb_carve_frag_list() drop_monitor friends

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Eric Dumazet <edumazet@xxxxxxxxxx>

commit ef527f968ae05c6717c39f49c8709a7e2c19183a upstream.

Whenever one of these functions pull all data from an skb in a frag_list,
use consume_skb() instead of kfree_skb() to avoid polluting drop
monitoring.

Fixes: 6fa01ccd8830 ("skbuff: Add pskb_extract() helper function")
