Jon Cinque	b1340d77a2	sdk: Make Packet::meta private, use accessor functions (#29092 ) sdk: Make packet meta private	2022-12-06 12:54:49 +01:00
behzad nouri	348fe9ebe2	verifies shred slot and parent in fetch stage (#26225 ) Shred slot and parent are not verified until window-service where resources are already wasted to sig-verify and deserialize shreds. This commit moves above verification to earlier in the pipeline in fetch stage.	2022-06-28 12:45:50 +00:00
behzad nouri	de612c25b3	removes shred wire layout specs from sigverify (#25520 ) sigverify_shreds relies on wire layout specs of shreds: https://github.com/solana-labs/solana/blob/0376ab41a/ledger/src/sigverify_shreds.rs#L39-L46 https://github.com/solana-labs/solana/blob/0376ab41a/ledger/src/sigverify_shreds.rs#L298-L305 In preparation of https://github.com/solana-labs/solana/pull/25237 which adds a new shred variant with different layout and signed message, this commit removes shred layout specification from sigverify and instead encapsulate that in shred module.	2022-05-26 13:06:27 +00:00
behzad nouri	880684565c	limits read access into Packet data to Packet.meta.size (#25484 ) Bytes past Packet.meta.size are not valid to read from. The commit makes the buffer field private and instead provides two methods: * Packet::data() which returns an immutable reference to the underlying buffer up to Packet.meta.size. The rest of the buffer is not valid to read from. * Packet::buffer_mut() which returns a mutable reference to the entirety of the underlying buffer to write into. The caller is responsible to update Packet.meta.size after writing to the buffer.	2022-05-25 16:52:54 +00:00
Justin Starry	cad1c41ce2	Add Packet::deserialize_slice convenience method	2022-05-24 17:31:14 +08:00
behzad nouri	c248fb3f51	renames Packet Meta::{,set_}addr methods to {,set_}socket_addr (#25478 ) In order to distinguish between Meta.addr field which is an IpAddr and the methods which refer to a SocketAddr.	2022-05-23 15:48:59 +00:00
behzad nouri	eff59193db	enforces that LAST_SHRED_IN_SLOT is also DATA_COMPLETE_SHRED (#24892 ) A data shred cannot be LAST_SHRED_IN_SLOT if not also DATA_COMPLETE_SHRED. So LAST_SHRED_IN_SLOT should also imply DATA_COMPLETE_SHRED: https://github.com/solana-labs/solana/blob/74b586ae7/ledger/src/shredder.rs#L116-L117 https://github.com/solana-labs/solana/blob/74b586ae7/core/src/broadcast_stage/standard_broadcast_run.rs#L80-L81 However current shred constructs allow specifying a shred which is LAST_SHRED_IN_SLOT but not DATA_COMPLETE_SHRED: https://github.com/solana-labs/solana/blob/74b586ae7/ledger/src/shred.rs#L117-L118 https://github.com/solana-labs/solana/blob/74b586ae7/ledger/src/shred.rs#L272-L273 The commit updates ShredFlags so that if a shred is not DATA_COMPLETE_SHRED it cannot be LAST_SHRED_IN_SLOT either.	2022-05-02 23:33:53 +00:00
behzad nouri	0f60665100	replaces Shred::new_empty_coding with Shred::new_from_parity_shard (#24749 ) Removing implementation details of shreds and payload offsets from shredder, so that shredder does not need to mutate payload: https://github.com/solana-labs/solana/blob/71ad12128/ledger/src/shred.rs#L968-L977 Also, Shred::new_from_data can simply obtain a slice as opposed to Option<&[u8]>: https://github.com/solana-labs/solana/blob/71ad12128/ledger/src/shred.rs#L268-L278	2022-04-27 18:04:10 +00:00
behzad nouri	895f76a93c	hides implementation details of shred from its public interface (#24563 ) Working towards embedding versioning into shreds binary, so that a new variant of shred struct can include merkle tree hashes of the erasure set.	2022-04-25 12:43:22 +00:00
behzad nouri	705ea53353	moves sign_shred and new_coding_shred_header out of Shredder (#24487 )	2022-04-19 20:00:05 +00:00
behzad nouri	01a096adc8	adds bitflags to Packet.Meta Instead of a separate bool type for each flag, all the flags can be encoded in a type-safe bitflags encoded in a single u8: https://github.com/solana-labs/solana/blob/d6ec103be/sdk/src/packet.rs#L19-L31	2022-01-04 13:53:40 +00:00

carllin	97f2bcff69	master: Add nonce to shreds repairs, add shred data size to header (#10109 ) * Add nonce to shreds/repairs * Add data shred size to header Co-authored-by: Carl <carl@solana.com>	2020-05-19 12:38:18 -07:00
