u-boot.git/net/fastboot_tcp.c, branch master Unnamed repository; edit this file 'description' to name the repository. net/tcp: improve tcp framework, use better state machine 2024-12-28T17:59:42+00:00 Mikhail Kshevetskiy mikhail.kshevetskiy@iopsys.eu 2024-12-28T10:46:32+00:00 bf962de97c375886fee0532f9d282a895d257ebb Changes: * Fix initial send sequence always zero issue * Use state machine close to RFC 9293. This should make TCP transfers more reliable (now we can upload a huge array of data from the board to external server) * Improve TCP framework a lot. This should make tcp client code much more simple. * rewrite wget with new tcp stack * rewrite fastboot_tcp with new tcp stack It's quite hard to fix the initial send sequence (ISS) issue with the separate patch. A naive attempt to fix an issue inside the tcp_set_tcp_header() function will break tcp packet retransmit logic in wget and other clients. Example: Wget stores tcp_seq_num value before tcp_set_tcp_header() will be called and (on failure) retransmit the packet with the stored tcp_seq_num value. Thus: * the same ISS must allways be used (current case) * or tcp clients needs to generate a proper ISS when required. A proper ISS fix will require a big redesing comparable with a this one.

Changes:
 * Fix initial send sequence always zero issue
 * Use state machine close to RFC 9293. This should make TCP
   transfers more reliable (now we can upload a huge array
   of data from the board to external server)
 * Improve TCP framework a lot. This should make tcp client
   code much more simple.
 * rewrite wget with new tcp stack
 * rewrite fastboot_tcp with new tcp stack

It's quite hard to fix the initial send sequence (ISS) issue
with the separate patch. A naive attempt to fix an issue
inside the tcp_set_tcp_header() function will break tcp packet
retransmit logic in wget and other clients.

Example:
  Wget stores tcp_seq_num value before tcp_set_tcp_header() will
  be called and (on failure) retransmit the packet with the stored
  tcp_seq_num value. Thus:
    * the same ISS must allways be used (current case)
    * or tcp clients needs to generate a proper ISS when
      required.

A proper ISS fix will require a big redesing comparable with
a this one.
