solana program write-buffer does not respect --buffer-authority

[ruuda]

Problem

solana program write-buffer does not respect --buffer-authority:

$ ~/.local/share/solana/install/releases/1.6.11/solana-release/bin/solana --url https://api.devnet.solana.com program write-buffer --buffer-authority 8JZPeAApMxn6UN3RDBZjHVGjgtnNuUdHdyyiLjnub8JC target/deploy/someprogram.so
Buffer: 2DjB5gvHvQ6aqTmmbTqsabg2uAYq48nxBKcPXFRv98Nf


$ ~/.local/share/solana/install/releases/1.6.11/solana-release/bin/solana --url https://api.devnet.solana.com program show 2DjB5gvHvQ6aqTmmbTqsabg2uAYq48nxBKcPXFRv98Nf

Buffer Address: 2DjB5gvHvQ6aqTmmbTqsabg2uAYq48nxBKcPXFRv98Nf
Authority: Bu3TFkuDsL8bzTcTv3FS71JzuEpWBKvjT3m4QWcw9rEP
Balance: 3.39334104 SOL
Data Length: 487376 (0x76fd0) bytes

Changing it afterwards does work:

$ ~/.local/share/solana/install/releases/1.6.11/solana-release/bin/solana --url https://api.devnet.solana.com program set-buffer-authority 2DjB5gvHvQ6aqTmmbTqsabg2uAYq48nxBKcPXFRv98Nf --new-buffer-authority 8JZPeAApMxn6UN3RDBZjHVGjgtnNuUdHdyyiLjnub8JC

Proposed Solution

Double check the code, is it actually using the buffer authority provided?
