Neil:
I am keeping an eye on attestation emails sent to the signatures list
(https://lore.kernel.org/signatures/) and I noticed that b4 isn't
properly finding your attestation data. I poked at this series:
- thread: https://lore.kernel.org/linux-amlogic/20200907081825.1654-1-narmstrong@baylibre.com
- attestation: https://lore.kernel.org/signatures/159946699508.19944.11132773619713429568@kernel.org
When we generate attestation hashes from the patches you submitted, we
get a different value for the "i" hash:
$ git mailinfo m p < 0001-dt-bindings-display-amlogic-meson-vpu-add-bindings-f.patch | egrep '^(Author|Email|Subject)' | sha256sum
7158b7d79fbd5342923a63ea14701fa75061a856f6eb30c9dfe83672894113ba -
Apparently, when you run it on your system during attestation generation
step, you get a different hash for i:
3753d76c-4b385c46-aa69b83c:
i: 3753d76ca01efcc78b682dc0f9feb582d67a1e9a6a89b0519cdf54a36eee5e0b
m: 4b385c46651635915366eba13de55a445ae3d41afd2d0e5da8bad270a08c0e70
p: aa69b83c2b5d484b33deec0c59135fdfe7290b658f29527590261abab8a4ac51
This is why when we're trying to find your attestation document, we are
not finding it:
Cache says looking up 7158b7d7-4b385c46-aa69b83c = 404
I am curious why this happens -- either the patches generated on your
system have different Author/Email/Subject values until git-send-email actually
runs, or git mailinfo output has changed between revisions. I would like to
understand this better so we can properly address it, if you're willing to lend
a hand.
Best,
Konstantin

Indeed, I usually only add partial To/Cc directly in the patches and the patchset-wise
to git send-email, would it be the issue ?
