Subject: Re: [RFC][PATCHES] fixes in methods exposed to rcu pathwalk
Date: Mon, 2 Oct 2023 03:52:56 +0100 [thread overview]
Message-ID: <20231002025256.GR800259@ZenIV> (raw)
In-Reply-To: <20231002022846.GA3389589@ZenIV>
PS: ceph ->d_revalidate() uses ->s_fs_info and stuff hanging off it
(mdsc) and I'm not familiar enough with the codebase to do anything
useful with it; AFAICS, there are UAF on fs shutdown, but I'd rather
leave that one to ceph folks. NTFS3 ->d_hash() and ->d_compare()
do blocking allocations, and that stuff can be called under
rcu_read_lock(); ->d_compare() pretty much always is called so...
