| |
Hi,
In e268337dfe26dfc7efd422a804dbb27977a3cccc, the logic for interacting with /dev/$pid/mem was changed. It seems that the requirement that the reader/writer must be actively attached to the inferior has been dropped. Is this wise, to allow multiple read/writers of /dev/$pid/mem even if they are not ptracing? The protection has been there for a while, and I don't see the reason for removing it. I can't find a discussion about this change -- where did that happen?
