Subject: [PATCH] skbuff: Fix a race between coalescing and releasing SKBs
Commit 1effe8ca4e34 ("skbuff: fix coalescing for page_pool fragment
recycling") allowed coalescing to proceed with non page pool page and page
pool page when @from is cloned, i.e.
to->pp_recycle --> false
from->pp_recycle --> true
skb_cloned(from) --> true
However, it actually requires skb_cloned(@from) to hold true until
coalescing finishes in this situation. If the other cloned SKB is
released while the merging is in process, from_shinfo->nr_frags will be
set to 0 toward the end of the function, causing the increment of frag
page _refcount to be unexpectedly skipped resulting in inconsistent
reference counts. Later when SKB(@to) is released, it frees the page
directly even though the page pool page is still in use, leading to
use-after-free or double-free errors. So it should be prohibited.
The double-free error message below prompted us to investigate:

Subject: [PATCH] net: ethernet: mtk_eth_soc: fix flow_offload related refcount
bug
Since we call flow_block_cb_decref on FLOW_BLOCK_UNBIND, we need to call
flow_block_cb_incref unconditionally, even for a newly allocated cb.
Fixes a use-after-free bug. Also fix the accidentally inverted refcount
check on unbind.
