Michael Brown	5de837cc67	Mildly ugly hack to force correct linkage.	vor 17 Jahren
Michael Brown	95adce0ce1	Add concept of transfer metadata, to be used by UDP in order to implement sendto()/recvfrom() equivalents.	vor 17 Jahren
Michael Brown	3acd51597a	Add sanity check and extra debug message	vor 17 Jahren
Michael Brown	1311b4194c	Eliminate PF_INET; just use the AF_INET from the struct sockaddr instead.	vor 17 Jahren
Michael Brown	b8618d76db	Modify data-xfer semantics: it is no longer necessary to call one of request(), seek() or deliver_xxx() in order to start the data flow. Autonomous generators must be genuinely autonomous (having their own process), or otherwise arrange to be called. TCP does this by starting the retry timer immediately. Add some debugging statements.	vor 17 Jahren
Michael Brown	1136c19fa4	Updated tcp.c to provide a standardised data transfer interface.	vor 17 Jahren
Michael Brown	3e2c6b6736	pkbuff->iobuf changeover Achieved via Perl using: perl -pi -e 's/pk_buff/io_buffer/g; s/Packet buffer/I\/O buffer/ig; ' \ -e 's/pkbuff\.h/iobuf.h/g; s/pkb_/iob_/g; s/_pkb/_iob/g; ' \ -e 's/pkb/iobuf/g; s/PKB/IOB/g;'	vor 17 Jahren
Michael Brown	3fd10074d8	SSL needs quite a lot of spare memory	vor 17 Jahren
Michael Brown	6d32f0e6e2	Changed to use the generic stream API.	vor 17 Jahren
Michael Brown	73b09ecba6	Use stdio.h instead of vsprintf.h	vor 17 Jahren
Michael Brown	c014f607a8	Use total free memory as advertised window. This seems to be sufficient to avoid drops even on slow NICs.	vor 17 Jahren
Michael Brown	06630a3036	Switch from calloc() to malloc()+memset() to match the practices used almost everywhere else.	vor 17 Jahren
Michael Brown	76aa9ad07d	Make TCP give up immediately when it receives -ENETUNREACH from tcpip_tx(). This avoids the irritating wait when you accidentally type "kernel pxelinux.0" before bringing up the network interface. Add ENETUNREACH to strerror()'s list.	vor 17 Jahren
Michael Brown	526d314266	Advertise a larger MSS to improve TCP performance.	vor 17 Jahren
Michael Brown	f008b77ba2	Allow an explicit network device to be specified for IP-layer transmissions.	vor 17 Jahren
Michael Brown	18e5353bed	Rename pkb_available() to pkb_tailroom() for consistency with Linux's skb_tailroom(). Add pkb_headroom().	vor 17 Jahren
Michael Brown	2eeb7c4fe7	Define "connected" as "when SYN is ACKed and we have already received SYN", or "when SYN is received and we have already had SYN ACKed" rather than just "when SYN is ACKed" This avoids spuriously calling the connected() method when we receive a RST,ACK in response to a SYN.	vor 17 Jahren
Michael Brown	b0daa99dce	Send RST packets when we get a non-matching connection, or receive an out-of-range ACK.	vor 17 Jahren
Michael Brown	eea1167a85	Accept RST on received packets	vor 17 Jahren
Michael Brown	94fc68895d	Improve consistency between TCP and UDP RX datapaths	vor 17 Jahren
Michael Brown	a0525a4ed3	Verify checksums on the RX datapath. Simplify checksum generation on the TX datapath.	vor 17 Jahren
Michael Brown	feb4f65d1e	Use auto-colourisation for debug messages. Truncate TX length to TCP window at time of transmission rather than at time of adding to TX packet; this is conceptually cleaner and also allows the application to call tcp_send() multiple times to build up a single packet.	vor 17 Jahren
Michael Brown	ce9819af27	Redefine TCP state to include "flags that have been sent" rather than "flags that are currently being sent". This allows at least one special case (checking that we haven't already sent a FIN in tcp_rx_fin()) to be collapsed.	vor 17 Jahren
Michael Brown	be31970e36	Don't send a second FIN if we receive a FIN while in FIN_WAIT_2	vor 17 Jahren
Michael Brown	61ed298bc7	Merge changes from mcb-tcp-fixes branch.	vor 17 Jahren
Michael Brown	5edb85c8b4	Work around another confused-by-RST bug	vor 17 Jahren
Michael Brown	b9f9230661	Work around another instance of the port re-use bug.	vor 17 Jahren
Michael Brown	cc0b92652f	Call closed() method only when the connection is genuinely in the TCP_CLOSED state (i.e. after the final FIN/ACK exchange), and has been removed from the list of TCP connections.	vor 17 Jahren
Michael Brown	fcc70c9d60	Ensure that tcp_rx() always frees its received packet buffer.	vor 17 Jahren
Michael Brown	28c711b91d	Killed off spurious <stdio.h> inclusion	vor 17 Jahren
Michael Brown	3fbfbad0f7	Avoid calling NULL methods!	vor 17 Jahren
Marty Connor	6ac78f6aff	added stdio.h to includes for DBG compilation	vor 18 Jahren
Nikhil Chandru Rao	dccb8358bd	Fixed a bug in the TCP state machine. Added a transition from ESTABLISHED to LAST_ACK on receiving a FIN,ACK	vor 18 Jahren
Michael Brown	f0718d562f	Don't call stop_timer() from within the timer expiry callback; it's already stopped. Don't call start_timer() when sending a dataless ACK. This may or may not be the right thing to do; I can't tell. Back out broken "send ACK only if required to" logic temporarily.	vor 18 Jahren
Nikhil Chandru Rao	3aff701001	Changed the TCP state machines behaviour in the ESTABLISHED state	vor 18 Jahren
Michael Brown	dc8b96b446	Temporarily work around the bug when port numbers are reused between subsequent runs.	vor 18 Jahren
Michael Brown	09688cb3b5	Correct some packet ownership and freeing bugs.	vor 18 Jahren
Michael Brown	43d601b678	out_flags was being set but never used. Use just random() to allocate initial sequence numbers; the previous algorithm ended up with a high probability of zeroing the high word.	vor 18 Jahren
Michael Brown	065a2a486d	Port the UDP port allocation code to TCP	vor 18 Jahren
Michael Brown	de0c36a98a	Remove some of the confusion surrounding the amount to strip off from a TCP packet before passing to newdata().	vor 18 Jahren
Marty Connor	ee9ae8130a	Remove _PROTOCOL macros for gcc 3.2 compatibility	vor 18 Jahren
Nikhil Chandru Rao	8bf38fb400	Corrected bugs in the TCP logic. There might be a few more which need to be taken care of.	vor 18 Jahren
Nikhil Chandru Rao	d2bdf81505	Removed some bugs in TCP	vor 18 Jahren
Nikhil Chandru Rao	cb42e573a0	Added retransmissions to TCP	vor 18 Jahren
Nikhil Chandru Rao	6714ec745a	Minor corrections	vor 18 Jahren
Michael Brown	467e9627cc	Added features that will be required for PXE UDP support. Introduced struct sockaddr_tcpip, to simplify code that deals with both IPv4 and IPv6 addresses. Reorganised parts of tcpip.c and udp.c.	vor 18 Jahren
Nikhil Chandru Rao	9225f4edac	TCP support	vor 18 Jahren
Michael Brown	8637834031	Made the temporary buffer part of the TCP senddata() API, to ease the transition away from uIP. Prepared ipv4.c for transition away from uIP.	vor 18 Jahren
Michael Brown	3c8aafa209	Simplify RX data path. Kill off the static single net device and move to proper dynamic registration (which we need with the new device model). Break the (flawed) assumption that all network-layer protocols can use ARP; such network-layer protocols (i.e. IPv4) must now register as an ARP protocol using ARP_NET_PROTOCOL() and provide a single method for checking the existence of a local network-layer address.	vor 18 Jahren
Michael Brown	bbd9e28061	Simplify TX datapath.	vor 18 Jahren
