Michael Brown	3a660f9b25	Update ftp.c and hello.c to use the generic async_operations API.	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	968501e323	For consistency	vor 18 Jahren
Michael Brown	bcdcd796fb	32kB window is actually larger than our typical receive ring size. Shrink to 4kB for now. We might want to see if it can be made genuinely indicative of the RX ring size in the new TCP implementation.	vor 18 Jahren
Michael Brown	bbd9e28061	Simplify TX datapath.	vor 18 Jahren
Michael Brown	d78581297b	Improve tcpdump legibility.	vor 18 Jahren
Michael Brown	48fb6c6dc2	Updated retry timer mechanism to incorporate smoothed RTT estimation. AoE now uses the retry timer mechanism.	vor 18 Jahren
Michael Brown	f6d20bb0f4	Put in a method to get the MAC address for the AoE target. (It's not elegant, but it works).	vor 18 Jahren
Michael Brown	99ef98d0bf	ATA devices are now asynchronous. The ATA layer itself now performs the async_wait(), though we may wish to move this higher up the stack, and consider making the block device model asynchronous. (There is only a marginal cost for synchronous devices, since they can simply call async_done() before returning; async_wait() will work seamlessly in this situation).	vor 18 Jahren
Michael Brown	68125bc441	Added generic asynchronous operations code. Removed data_in_len and data_out_len from ata_command structure; the lengths are implied by the sector count and the presence of the data_in or data_out pointers. Changed AoE code to use subcommands by default, and made aoe_issue() nonblocking (with completion via async_wait()).	vor 18 Jahren
Michael Brown	552b4a178e	One bit of an ASCII character can make a big difference.	vor 18 Jahren
Michael Brown	1db1a6dad3	Added first sketch of a generic retry timer mechanism. The idea is to use these timer objects in AoE and UDP protocols (where there is no underlying retransmission mechanism) without requiring each protocol to implement its own individual retry logic. Eventually, we should be able to use the same timer code for TCP retransmissions as well.	vor 18 Jahren
Michael Brown	6541338897	Handle multi-sector reads by splitting them into subcommands.	vor 18 Jahren
Michael Brown	9a2a52693d	Initial AoE implementation. Limitations are: Cannot yet handle reads of more than two sectors No retransmission No way to find out a target's MAC address (this proof of concept uses broadcasts) These limitations shall not last long! :)	vor 18 Jahren
Michael Brown	f743de4858	Added tcp_kick(). This speed up LILO and GRUB booting by almost two orders of magnitude.	vor 18 Jahren
Michael Brown	cd3ecac809	Avoid causing TX overflow on small TX queues.	vor 18 Jahren
Michael Brown	69b1f24a97	I have no idea how this ever worked before.	vor 18 Jahren
Michael Brown	6c50564724	Make PKB_ZLEN the minimum possible size of packet buffer (to allow for hardware that can't autopad).	vor 18 Jahren
Michael Brown	1dbafa8950	Tidied up debugging messages	vor 18 Jahren
Michael Brown	b9cbae58fa	Expert advice tells me that we do have to explicitly state the options even when we want to use the defaults.	vor 18 Jahren
Michael Brown	d48d0fb1bb	Add the concept of a "user pointer" (similar to the void __user * in the kernel), which encapsulates the information needed to refer to an external buffer. Under normal operation, this can just be a void * equivalent, but under -DKEEP_IT_REAL it would be a segoff_t equivalent. Use this concept to avoid the need for bounce buffers in int13.c, which reduces memory usage and opens up the possibility of using multi-sector reads. Extend the block-device API and the SCSI block device implementation to support multi-sector reads. Update iscsi.c to use user buffers. Move the obsolete portions of realmode.h to old_realmode.h. MS-DOS now boots an order of magnitude faster over iSCSI (~10 seconds from power-up to C:> prompt in bochs).	vor 18 Jahren
Michael Brown	c69c1ec540	Documented login parameters that we negotiate.	vor 18 Jahren
Michael Brown	a280587cde	iSCSI writes seem to be working (at least, the ethereal trace shows no errors; still need to verify data integrity). SCSI response PDUs are handled: status and sense data (if available) are returned via the scsi_command structure. Updated iSCSI session parameter usage.	vor 18 Jahren
Michael Brown	813a052dc3	Set ErrorRecoveryLevel=0 (we don't want to have to handle it).	vor 18 Jahren
Michael Brown	f25731d08f	Split "iSCSI as a SCSI device" out from "iSCSI as a TCP protocol".	vor 18 Jahren
Michael Brown	2421723a15	Rewrote printf and friends to better support standard C semantics.	vor 18 Jahren
Michael Brown	5009f8d6a2	Provide a SCSI device interface to the iSCSI protocol	vor 18 Jahren

Michael Brown	9e1becaf8a	Merge TCP aborted(), timedout() and closed() methods into a single closed() method with a reason code.	vor 19 Jahren
Michael Brown	8afb6303fb	Half-way tidy	vor 19 Jahren
Michael Brown	04b6a1e004	Make all TCP methods optional; at least FTP data is a read-only connection and so legitimately ignores acked() and senddata().	vor 19 Jahren
Michael Brown	aec0e127d2	Proof-of-concept FTP implementation	vor 19 Jahren
Michael Brown	01bd78d62a	Created net/tcp and moved hello.c there	vor 19 Jahren
Michael Brown	7af478b30d	Make tcp_connect() void; it will eventually have no failure case.	vor 19 Jahren
Michael Brown	9c9208a132	Put the TCP connection periodic processing in tcp.c, where it belongs.	vor 19 Jahren
Michael Brown	592a5a99c8	Moved uIP and tcp.c from proto/ to net/	vor 19 Jahren
Michael Brown	352bf1bda2	Move init.h to gpxe/init.h.	vor 19 Jahren
Michael Brown	bac97eb979	Change semantics of network API so that packet-absorbing calls always take ownership of the packet, rather than doing so only if they return success. This breaks semantic compatibility with Linux's hard_start_xmit() method, but means that we don't have to worry so much about error cases. Split mechanism of processing received packets (net_rx_process()) out from policy (net_step()), preparatory to putting net_step() in a separate object.	vor 19 Jahren
Michael Brown	129c6c3968	Network layer now works as a proof of concept	vor 19 Jahren
Michael Brown	1488cd3b73	Fix a couple of broken assertions, and align the buffer correctly.	vor 19 Jahren
Michael Brown	fee8b91015	D'oh	vor 19 Jahren
Michael Brown	cf3783b4ca	Actually, it's probably a good idea to have packet buffers avoid 4kB crossings.	vor 19 Jahren
Michael Brown	00a1de964d	Update to use POSIX-like API.	vor 19 Jahren
Michael Brown	53f78346bf	Network API now allows for multiple network devices (although the implementation allows for only one, and does so without compromising on the efficiency of static allocation). Link-layer protocols are cleanly separated from the device drivers. Network-layer protocols are cleanly separated from individual network devices. Link-layer and network-layer protocols are cleanly separated from each other.	vor 19 Jahren

Michael Brown	6209bd873a	First sketch of a new net device API.	vor 19 Jahren
Michael Brown	bdc8190c8d	Remove the concept of the media-independent link-layer header and replace it with metadata in the pkb structure. This is required since UNDI will want to be able to parse the link-layer header without destroying it.	vor 19 Jahren
Michael Brown	9f67ad9db0	First version. ARP protocol independence in less than the size of uIP's Ethernet-and-IPv4-only ARP module. :)	vor 19 Jahren
