Subject: Re: [PATCH 13/13] selftests/bpf: add uprobe_multi test on overlayfs without data
Date: Sun, 15 Nov 2026 14:12:19 +0000 [thread overview]
Message-ID: <sashiko-outbox-215570@kernel.org> (raw)
In-Reply-To: <20261115-work-ovl-d_real-v1-13-ca155efbcb2e@kernel.org>
> Add a uprobe_multi test that attaches to a metacopy file on overlayfs
> whose redirect into a data-only layer points at nothing:
>
> - the overlayfs is set up in a child in its own mount namespace
>
> - BPF_LINK_CREATE must fail with ENOENT from the lazy lowerdata lookup
>
> - skip if overlayfs with data-only layers isn't available
>
> Before d_real() could fail this got an EIO from uprobe_register().
>
