Hi,

CVE-2021-4001: bpf: Fix toctou on read-only map''s constant scalar tracking

CVSS v3 score is not provided.

This bug was introduced in 5.5-rc1 and fixed in 5.16-rc2. Patch for 5.15 is in stable-rt tree. Patch for 5.4(https://lore.kernel.org/stable/163757721744154@kroah.com/) and 5.10(https://lore.kernel.org/stable/1637577215186161@kroah.com/) are failed to apply. However, this bug was introduced in 5.5-rc1 so 5.4 can be ignored?
Fixed status

mainline: [353050be4c19e102178ccc05988101887c25ae53]

I attached a patch for 5.10.

Thanks, LGTM.
I think it would be better to add the comment of the conflict fixing.
e.g. https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=linux-5.10.y&id=1ada86999dc84b852fcc32962f4002e939f4beb7

Best regards,
Nobuhiro
