| 1 |
* A new API: protosockets that are similar to BSD sockets but does not |
|---|
| 2 |
require any underlying multithreading system. |
|---|
| 3 |
|
|---|
| 4 |
* Very rudimentary IPv6 support |
|---|
| 5 |
|
|---|
| 6 |
* New application: DHCP client. Web server rewritten with protosockets. |
|---|
| 7 |
|
|---|
| 8 |
* Removed uIP zero-copy functionality in order to simplify uIP device |
|---|
| 9 |
driver coding: outbound packets are now *always* stored in full in |
|---|
| 10 |
the uip_buf buffer. |
|---|
| 11 |
|
|---|
| 12 |
* Checksum computation is now part of uip.c, but it still is possible |
|---|
| 13 |
to implement them in assembly code by specifying a configuration |
|---|
| 14 |
option. Checksum code now runs on architectures with 2-byte alignment. |
|---|
| 15 |
|
|---|
| 16 |
* Added TCP persistent timer. |
|---|
| 17 |
|
|---|
| 18 |
* Made all IP address representations use the new uip_ipaddr_ip |
|---|
| 19 |
datatype for clarity. |
|---|
| 20 |
|
|---|
| 21 |
* Updated window behavior so that sending to a host with a small open |
|---|
| 22 |
window works better now. |
|---|
| 23 |
|
|---|
| 24 |
* UDP API change: uip_udp_new() now takes port numbers in network byte |
|---|
| 25 |
order like TCP functions. |
|---|
| 26 |
|
|---|
| 27 |
* Allow reception of packets when no IP address is configured to make |
|---|
| 28 |
DHCP work. |
|---|
| 29 |
|
|---|
| 30 |
* Moved Ethernet address into main uIP module from ARP module. |
|---|
| 31 |
|
|---|
| 32 |
* Made constants explicit #defines and moved them out of the code |
|---|
| 33 |
(header sizes, TCP options, TCP header length field). |
|---|
| 34 |
|
|---|
| 35 |
* If uip_len is less than that reported by the IP header, the packet |
|---|
| 36 |
is discarded. If uip_len is greater than the length reported by the |
|---|
| 37 |
IP header, uip_len is adjusted. |
|---|
| 38 |
|
|---|
| 39 |
* Moved header size definitions into header file. |
|---|
| 40 |
|
|---|
| 41 |
* Added uIP call for polling an application without triggering any |
|---|
| 42 |
timer events. Removed redundant assignments of uip_len and uip_slen. |
|---|
| 43 |
|
|---|
| 44 |
* Removed compiler warning about icmp_input label being defined when |
|---|
| 45 |
UIP_PINGADDRCONF was not used. |
|---|
| 46 |
|
|---|
| 47 |
* Added UIP_APPDATA_SIZE macro that holds the available buffer size |
|---|
| 48 |
for user data. |
|---|
| 49 |
|
|---|
| 50 |
* Added uip_udp_bind() call. |
|---|
| 51 |
|
|---|
| 52 |
* Moved checksum code into main uIP module. |
|---|
| 53 |
|
|---|
| 54 |
* Switched the TCP, UDP and IP header structures to be structs rather |
|---|
| 55 |
than typedefs. |
|---|
| 56 |
|
|---|
| 57 |
* Prefixed TCP state names with UIP_ to avoid name space |
|---|
| 58 |
contamination. |
|---|
| 59 |
|
|---|
| 60 |
* Changed declarations of uip_appdatap and friends to void * to avoid |
|---|
| 61 |
explicit typecasts. |
|---|
| 62 |
|
|---|
| 63 |
* Bugfixes |
|---|
| 64 |
|
|---|
| 65 |
o TCP: Fixed bug with high byte of peer window size. |
|---|
| 66 |
|
|---|
| 67 |
o TCP: Fixed bug that in some cases prevented concurrent reception and |
|---|
| 68 |
transmission of TCP data. |
|---|
| 69 |
|
|---|
| 70 |
o TCP: uip_connect() didn't correctly calculate age of TIME_WAIT |
|---|
| 71 |
connections. |
|---|
| 72 |
|
|---|
| 73 |
o TCP: Array index for uip_conns[] array was out of bounds in |
|---|
| 74 |
comparison. Comparison changed to make index within bounds. |
|---|
| 75 |
|
|---|
| 76 |
o TCP: if the remote host crashes and tries to reestablish an old |
|---|
| 77 |
connection, uIP should respond with an ACK with the correct |
|---|
| 78 |
sequence and acknowledgment numbers, to which the remote host |
|---|
| 79 |
should respond with an ACK. uIP did not respond with the correct |
|---|
| 80 |
ACK. |
|---|
| 81 |
|
|---|
| 82 |
o TCP: Fixed check for SYNACK segment: now checks only relevant TCP |
|---|
| 83 |
control flags and discards flags reserved for future expansion. |
|---|
| 84 |
|
|---|
| 85 |
o TCP: Fixed bug where uIP did not inform application that a connection |
|---|
| 86 |
had been aborted during an active open. |
|---|
| 87 |
|
|---|
| 88 |
o TCP: FIN segment was accepted even though application had stopped |
|---|
| 89 |
incoming data with uip_stop(). |
|---|
| 90 |
|
|---|
| 91 |
o TCP: A FINACK segment would not always correctly acknowledge data. |
|---|
| 92 |
|
|---|
| 93 |
o UDP: checksums are now calculated after all fields have been |
|---|
| 94 |
filled in. |
|---|
| 95 |
|
|---|
| 96 |
o UDP: network byte order on lastport in uip_udp_new(). |
|---|
| 97 |
|
|---|
| 98 |
o IP: memset() bugs in IP fragment reassembly code fixed. |
