bincode::serialized_sized requires constructing a temporary object and
it is slow. Silently changing serialized size of these structs can also
be a backward incompatible change.
This commit instead hard-codes serialized size of VoteState, Feature and
Nonce, and defines the functions as const. Added tests verify hard-coded
values.
Most nodes in the cluster receive the same shred from two different
nodes: parent, and the first node of their neighborhood:
https://github.com/solana-labs/solana/blob/a8c695ba5/core/src/cluster_nodes.rs#L178-L197
Because of the erasure codings, half of the shreds are already
redundant. So this redundant propagation path will only add extra
overhead.
Additionally the very first node of the broadcast tree has 2x fanout
(i.e. 400 nodes) which adds too much load at one node.
This commit simplifies the broadcast tree by dropping the redundant
propagation path and removing the 2x fanout at root node.

- Tweak linker script
Ensure that all read only sections end up in one segment, and
everything else in other segments. Discard .eh_frame, .hash and
.gnu.hash since they are unused.
- Don't create invalid string slices in stdout/stderr on Solana
- Report exceeded stack size as a warning if dynamic frames are off
- Native support for signed division in SBF
Adds BPF_SDIV, which is enabled only for the SBF subtarget.
- Introduce dynamic stack frames and the SBFv2 flag
Dynamic stack frames are currently opt-in and enabled setting
cpu=sbfv2. When sbfv2 is used, ELF files are flagged with
e_flags=EF_SBF_V2 so the runtime can detect it and react
accordingly.
* Adds transaction_context and instruction_context where invoke_context.get_keyed_accounts() is used.
* Use instruction_context.get_instruction_data() instead of an explicit parameter.
* Removes instruction_data parameter from Executor::execute().
* Removes instruction_data parameter from ProcessInstructionWithContext.
* transaction-status: Add return data to meta
* Add return data to simulation results
* Use pretty-hex for printing return data
* Update arg name, make TransactionRecord struct
* Rename TransactionRecord -> ExecutionRecord
