Detailed Description

RFC 9000 19.6 / 7.5: reassemble CRYPTO frames received in a Handshake (or Initial) packet payload into a single in-order byte stream of TLS handshake messages.

Out-of-order and split frames are placed at their offset; only the contiguous prefix from offset 0 is exposed to TLS. Fixed buffer, no alloc.

Function Documentation

crecv_collect()

int crecv_collect	(	crecv *	s,
		const u8 *	frames,
		usz	len )

Walk a payload, write every CRYPTO frame at its offset, ignore other frames.

Updates the contiguous prefix.

Parameters

s	reassembly state
frames	the packet payload to walk
len	length of frames in bytes

Returns

1, or 0 if a CRYPTO frame falls outside the buffer (RFC 9000 19.6).

crecv_init()

void crecv_init

(

crecv *

s

)

Start with an empty reassembly buffer.

Parameters

s	reassembly state to initialize
