Specifying the multisig PDA as transaction execution signer.

[eloylp]

Hey hello 👋

Whats the problem we are trying to solve ?

We would like to use the Squads protocol multisig Rust SDK for creating a transaction, which would upgrade an arbitrary Solana program by calling the solana_program::bpf_loader_upgradeable::upgrade at the moment of proposal execution.

What we are finding so far ?

We are finding that the execute_message method, is only adding as signers transaction level related seeds we cannot set as upgrade_authority of target programs due to their lifetime (per tx).

What we are expecting to happen ?

We would like to add the multisig level account as signer of the CPI, so the target program to upgrade can set it as its own upgrade_authority, granting the upgrade operation through the multisig after a successful votation.

We could also use this method for changing the upgrade_authority to a new one if the multisig members decides so ...

Is this scenario possible ? Thanks in advance :)
