[PATCH openEuler-1.0-LTS 01/40] fuse: fix page stealing
by Yang Yingliang 27 Jan '22

27 Jan '22

From: Miklos Szeredi <mszeredi(a)redhat.com> stable inclusion from linux-4.19.219 commit 65f1f3eb09a3907c5f5edaff6c473b99e49e6020 -------------------------------- commit 712a951025c0667ff00b25afc360f74e639dfabe upstream. It is possible to trigger a crash by splicing anon pipe bufs to the fuse device. The reason for this is that anon_pipe_buf_release() will reuse buf->page if the refcount is 1, but that page might have already been stolen and its flags modified (e.g. PG_lru added). This happens in the unlikely case of fuse_dev_splice_write() getting around to calling pipe_buf_release() after a page has been stolen, added to the page cache and removed from the page cache. Fix by calling pipe_buf_release() right after the page was inserted into the page cache. In this case the page has an elevated refcount so any release function will know that the page isn't reusable.

From: Eric Dumazet <edumazet(a)google.com> mainline inclusion from mainline-v5.16-rc1 commit c4777efa751d293e369aec464ce6875e957be255 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I4RYXI CVE: NA -------------------------------- While commit 097b9146c0e2 ("net: fix up truesize of cloned skb in skb_prepare_for_shift()") fixed immediate issues found when KFENCE was enabled/tested, there are still similar issues, when tcp_trim_head() hits KFENCE while the master skb is cloned. This happens under heavy networking TX workloads, when the TX completion might be delayed after incoming ACK.
