8014473918 TCP: Update our side's ack number based on the other side's seq number. 2019-03-14 11:45:22 +01:00

54e7df0586 Kernel: Add SocketHandle helper class that wraps locked sockets. 
This allows us to have a comfy IPv4Socket::from_tcp_port() API that returns
a socket that's locked and safe to access. No need to worry about locking
at the client site.

3d5296a901 IPv4: Last burst of TCP hacking for today. 
Connecting to a test server and exchanging data back and forth works.

be46f1bb1f IPv4: More work on the TCP implementation. 
Reading from the peer now kinda works. Something still going wrong with
sending packets but it's getting closer.
 2019-03-14 01:00:10 +01:00

66d55f8e0c IPv4: More work on the TCP implementation. 
I can now establish a connection to my little test server on the host.

032d9d7065 IPv4: More hacking on bringing up TCP support. 
This was a bit more complicated than I expected, but it's moving forward.
 2019-03-13 23:14:30 +01:00
Andreas Kling
7aba68d51c Userland+LibC: Add a new little "tc" program for testing TCP. 
Also added send() and recv() to LibC in support of this. They are just
wrappers around sendto() and recvfrom().

c588653f76 IPv4: Begin fleshing out TCP support. 2019-03-13 17:17:07 +01:00

ef5d0a397c IPv4: Do the TCP-to-socket mapping in the same way as UDP. 
We don't actually have TCP support yet, but we'll get there soon. :^)
 2019-03-13 16:43:42 +01:00
Andreas Kling
3ad9561b80 IPv4: Use the UDP-to-socket map to handle incoming UDP packets. 2019-03-13 16:23:22 +01:00
Andreas Kling
209a16bb7f IPv4: Dynamically allocate the UDP source port if needed. 2019-03-13 16:05:56 +01:00
Andreas Kling
4dddf949c8 IPv4: More work on UDP support. 
I'm now able to connect to a simple UDP server on my host machine and
exchange some data. Very cool! :^)
 2019-03-13 15:40:30 +01:00

48431b3535 LibC: Add netinet/in.h 2019-03-13 15:09:54 +01:00
Andreas Kling
a9dc332a11 IPv4: recvfrom() shouldn't care about what's in the outparam on entry. 2019-03-13 15:00:28 +01:00
Andreas Kling
ea6a537b70 Userland: Add a simple utility for UDP testing. 2019-03-13 15:00:02 +01:00
Andreas Kling
19a51132f5 Kernel: recvfrom() should treat the address arguments as outparams. 2019-03-13 14:47:21 +01:00
Andreas Kling
b59d588c04 Kernel: Start fleshing out an UDP implementation. 2019-03-13 14:22:27 +01:00
Andreas Kling
562663df7c Add support for socket send/receive timeouts. 
Only the receive timeout is hooked up yet. You can change the timeout by
calling setsockopt(..., SOL_SOCKET, SO_RCVTIMEO, ...).

Use this mechanism to make /bin/ping report timeouts.

7bcd386338 NetworkAdapter: Use a ByteBuffer instead of kmalloc/kfree in send(). 2019-03-13 13:12:29 +01:00

60db082fdd AK: Fix node leak in SinglyLinkedList::take_first(). 2019-03-13 13:11:23 +01:00
Andreas Kling
cf250e1245 More work on IPv4 sockets and /bin/ping. 
It's now actually possible to ping other hosts on the network! :^)
I've switched the "run" script over to starting QEMU with user networking
since that works better for my testing needs right now.

ce7c302933 Kernel: Oops, gettimeofday()'s tv_usec should be micro, not milliseconds. 2019-03-13 03:25:18 +01:00
Andreas Kling
a7d5e9781a Kernel+LibC+Userland: Yet more networking bringup hacking. 
All ICMP sockets now receive all ICMP packets. All this buffering is gonna
need some limits and such.
 2019-03-12 17:27:07 +01:00
Andreas Kling
a017a77442 Kernel+LibC+Userland: Start working on an IPv4 socket backend. 
The first userland networking program will be "ping" :^)
 2019-03-12 15:51:42 +01:00
Andreas Kling
8e667747f0 Kernel: Add a way to look up NetworkAdapters by IPv4 address. 2019-03-12 13:30:36 +01:00

c6a2012fe9 Kernel: Collect IPv4 stuff in IPv4.h and ARP stuff in ARP.h. 2019-03-12 12:49:01 +01:00
Andreas Kling
87ecf290f4 Kernel: More work on the ICMP and IPv4 support. 2019-03-12 12:43:30 +01:00
Andreas Kling
9858be636f Kernel: Fix up the ICMP implementation to generate correct Echo replies. 
Serenity now responds to ping. :^)
 2019-03-12 11:44:38 +01:00
Andreas Kling
75e0ddd46a Kernel: More work on ICMP support. 
We can now kinda sorta respond to ICMP::EchoRequest although there's
still something not entirely right with the packets.
 2019-03-12 04:40:13 +01:00
Andreas Kling
5bd9844dd6 Kernel: Start adding IPv4 support, starting with ICMP echo messages. 
This doesn't work correctly yet, but it's getting nice enough to commit.

05c1a79454 Kernel: Minor style cleanup in NetworkTask. 2019-03-12 00:01:07 +01:00
Andreas Kling
318b01e055 Kernel: Bring up enough networking code that we can respond to ARP requests. 
This is all pretty rickety but we can now respond to "arping" from the host
while running inside QEMU. Very cool. :^)
 2019-03-11 23:21:38 +01:00
Andreas Kling
10dcd3a47f GTextEditor: Make sure the scroll corner helper widget is filled in. 2019-03-11 12:52:07 +01:00
Andreas Kling
35098cbde1 Kernel: Add a NetworkTask and a received network packet queue. 
It will be easier to deal with incoming packets in a separate task.
 2019-03-11 12:43:45 +01:00
