Michael Brown	48bdde5d7b	Taken from Linux's md5.c. This implementation is not very size-efficient, and will probably be rewritten. The md5.c from MatrixSSL is too ugly to consider importing.	2006-09-11 16:30:36 +00:00

Michael Brown	78dd963c1f	Check to see if we've reached the end of the map before attempting to skip past an empty region, otherwise we end up generating an infinitely long e820 map. (Yes, there are real systems that provide e820 maps with a zero-length region at the end...)	2006-08-31 13:25:45 +00:00

Michael Brown	5a54225aef	Added support for INT 13,15; NTLDR calls it (though it may not actually do anything with the result, since it carried on using us even when we returned failure).	2006-08-27 01:22:01 +00:00
Michael Brown	40724431e8	Added support for INT 13,15; NTLDR calls it (though it may not actually do anything with the result, since it carried on using us even when we returned failure).	2006-08-26 23:42:02 +00:00
Michael Brown	19883779ba	Use TEXT16_CODE() rather than manually specifying ".code16" etc, since our manual ".code32" will break a KEEP_IT_REAL build.	2006-08-24 18:43:28 +00:00
Michael Brown	028bc034e4	Always update the PnP checksum, even if the ident string is not being set.	2006-08-24 17:56:46 +00:00

Michael Brown	97439cb6eb	Kill off poll_interruptions(); it is lethal when we're acting as a PXE stack or INT 13 emulator etc.	2006-08-14 22:29:51 +00:00

Michael Brown	c3a4f3c5da	Towards an RFC2988-compliant timer.	2006-08-09 15:54:17 +00:00
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.	2006-08-09 15:50:20 +00:00
Nikhil Chandru Rao	3aff701001	Changed the TCP state machines behaviour in the ESTABLISHED state	2006-08-09 15:04:26 +00:00

Michael Brown	09688cb3b5	Correct some packet ownership and freeing bugs.	2006-08-09 14:27:07 +00:00
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.	2006-08-09 13:35:03 +00:00
Michael Brown	065a2a486d	Port the UDP port allocation code to TCP	2006-08-09 12:08:20 +00:00
Michael Brown	de0c36a98a	Remove some of the confusion surrounding the amount to strip off from a TCP packet before passing to newdata().	2006-08-09 12:01:09 +00:00
Michael Brown	867c7aef59	iphdr->hlen includes the IP header, so truncate packet before stripping the header. Also fix an htons/ntohs confusion.	2006-08-09 11:52:53 +00:00
Marty Connor	ee9ae8130a	Remove _PROTOCOL macros for gcc 3.2 compatibility	2006-08-09 04:42:14 +00:00

Michael Brown	0dd0a8366e	Removed obsolete line merged in with the cmdline stuff	2006-08-09 03:22:29 +00:00
Michael Brown	504a705d9e	Do no evil. :)	2006-08-09 03:21:02 +00:00
Michael Brown	c9e6c33bba	Attempt a PXE NBP boot as the TFTP test.	2006-08-09 03:00:11 +00:00
Michael Brown	f018da8215	Implement enough of PXENV_GET_CACHED_INFO to support pxelinux.	2006-08-09 02:59:19 +00:00
Michael Brown	75d26d884a	Added pxe_netdev; a slight hack for now, but will need to be done properly for the PXE UNDI API anyway.	2006-08-09 02:58:27 +00:00
Michael Brown	e9561aafc0	Derive xid dynamically from the netdev, so that we can call create_dhcp_packet() from pxe_preboot.c, after the dhcp_session is long gone. Expose the functions required by pxe_preboot.c	2006-08-09 02:56:40 +00:00
Michael Brown	56c995ff60	Aborted	2006-08-09 02:37:05 +00:00
Marty Connor	41af7457a8	Merge of Fredrik Hultin command_line	2006-08-09 02:30:35 +00:00
Michael Brown	691557281f	Add a couple of small but vital parts to PXENV_UDP_WRITE.	2006-08-09 01:57:02 +00:00
Michael Brown	a3d508b648	Clarified packet ownership transfer between a few functions. Added a large number of missing calls to free_pkb(). In the case of UDP, no received packets were ever freed, which lead to memory exhaustion remarkably quickly once pxelinux started up. In general, any function with _rx() in its name which accepts a pk_buff must either call free_pkb() or pass the pkb to another _rx() function (e.g. the next layer up the stack). Since the UDP (and TCP) layers don't pass packet buffers up to the higher-layer protocols (the "applications"), they must free the packet buffer after calling the application's newdata() method.	2006-08-09 01:24:32 +00:00
Michael Brown	fd07f56f0d	Note to self: learn to count.	2006-08-09 00:56:07 +00:00
Michael Brown	843bcc291d	Added missing __from_text16()s when passing pointers to PXE NBP.	2006-08-09 00:39:21 +00:00
Michael Brown	71754ada2a	Allow linking by converting functions to stubs	2006-08-09 00:25:29 +00:00

Michael Brown	751ae718bd	pxe_int_1a is needed by pxe_call.c	2006-08-09 00:16:57 +00:00
Michael Brown	d1a123b1f4	Added TFTP test code (currently just dumps file to console).	2006-08-09 00:09:29 +00:00
Michael Brown	3611cb17b7	Initial (untested) implementation of TFTP over the new UDP API.	2006-08-08 23:45:52 +00:00
Michael Brown	eda79ec32b	The prototype for strcasecmp() is apparently in strings.h.	2006-08-08 22:52:16 +00:00
Nikhil Chandru Rao	409f69a08a	Changed ipv4_dump() to consume only one line.	2006-08-08 22:26:35 +00:00
Nikhil Chandru Rao	8bf38fb400	Corrected bugs in the TCP logic. There might be a few more which need to be taken care of.	2006-08-08 22:25:20 +00:00
Michael Brown	72cd29f13c	Added some TFTP definitions for use with the new UDP API.	2006-08-08 22:01:16 +00:00
Michael Brown	18c112d205	Added (not yet tested) PXE API entry point and support functions.	2006-08-08 20:43:33 +00:00

Michael Brown	68e33224ef	gcc3 compatibility: removed ARP_NET_PROTOCOL().	2006-08-08 17:44:25 +00:00
Nikhil Chandru Rao	d2bdf81505	Removed some bugs in TCP	2006-08-08 03:42:30 +00:00
Nikhil Chandru Rao	cb42e573a0	Added retransmissions to TCP	2006-08-07 18:52:26 +00:00
Michael Brown	010288577f	Add very, very quick and dirty hello world test	2006-08-07 18:49:10 +00:00
Michael Brown	885a630ddf	Fix routing when a gateway exists. This should probably be split into a separate function.	2006-08-07 17:51:19 +00:00
Michael Brown	8a3f4b7de6	Set a NUL terminator before calling inet_aton.	2006-08-07 17:50:41 +00:00
Michael Brown	ecdcdea1af	Remove unused attribute from __table macros; the tables are no longer static since otherwise gcc4 optimises them away completely. Also, it really is an error if the table start and end are unused, so they certainly shouldn't be marked with attribute unused.	2006-08-07 17:06:31 +00:00
Michael Brown	d0e4f198d6	Add iSCSI to the DHCP tests. Start updating iscsi.c to use Nikhil's TCP API.	2006-08-07 16:48:24 +00:00
Nikhil Chandru Rao	6714ec745a	Minor corrections	2006-08-07 07:37:23 +00:00
Michael Brown	eb24eece0e	Convert some trivial functions to static inlines.	2006-08-03 23:42:03 +00:00
Michael Brown	ffe0e24249	Make the UDP senddata() methods return a status code. udp_connect() now follows the standard BSD sockets semantics and simply sets the default address for outgoing packets; it doesn't filter incoming packets.	2006-08-03 23:10:14 +00:00
Michael Brown	a0a872f7f1	Updated PXE UDP implementation to use the new Etherboot UDP API. Updated PXE API dispatcher to use copy_{to,from}_user, and moved to arch/i386 since the implementation is quite architecture-dependent. (The individual PXE API calls can be largely architecture-independent.)	2006-08-02 23:08:10 +00:00
Michael Brown	e24a6cb525	Moved the basic struct sockaddr out of in.h.	2006-08-02 00:06:30 +00:00
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.	2006-08-02 00:02:21 +00:00
Nikhil Chandru Rao	9225f4edac	TCP support	2006-08-01 20:46:50 +00:00
Nikhil Chandru Rao	c24546c70b	Minor changes to the network layer rx() functions	2006-08-01 20:27:26 +00:00
Michael Brown	beadd82208	Remove unused functions.	2006-08-01 14:26:02 +00:00
Michael Brown	1ebb68e49a	Renamed trans_{rx,tx}() to tcpip_{rx,tx}(), since they are specific to the TCP/IP protocol suite (rather than being general transport-layer functions).	2006-08-01 14:22:04 +00:00
Michael Brown	3a0e293123	Renamed tcpip_if.[ch] to tcpip.[ch]	2006-08-01 14:18:09 +00:00
Michael Brown	21c3d63c2e	We shouldn't need to allocate a TX packet buffer when calling newdata(); if the application wants to send data then it will have to use the normal senddata() mechanism.	2006-08-01 14:13:58 +00:00
Michael Brown	ae277992c2	Request bootfile name; it doesn't seem to be automatically supplied by all servers.	2006-08-01 14:12:27 +00:00
Michael Brown	6e3e5efaed	Accept '%i' as a synonym for '%d'.	2006-07-25 14:33:20 +00:00
Michael Brown	9e761f5f28	Print out "DHCP..." message just in case people think the demo is sitting there doing nothing when it's actually waiting for a DHCP reply.	2006-07-20 14:20:11 +00:00
Michael Brown	a92d242008	Allow an AoE boot to be directed via DHCP, so that we have a proof of concept demo that actually does something useful.	2006-07-20 14:15:23 +00:00
Michael Brown	3085f03ad4	Request Etherboot encapsulated options. Parameter request list is yet another option that ISC dhcpd ignores unless it's in the main options block. Fix logic error in parsing file and sname fields.	2006-07-20 14:14:41 +00:00
Michael Brown	b26806cf18	Add dhcp_snprintf() for extracting DHCP string options.	2006-07-20 14:13:11 +00:00
Michael Brown	7ca8bcd98c	Print out the lease time, just to show how easy it is.	2006-07-20 03:02:34 +00:00
Michael Brown	16d04386b6	Switch default stack to Nikhil's TCP/IP stack	2006-07-20 02:53:15 +00:00
Michael Brown	e74e20cb55	Remove the static IP address hack from netdevice.c, and change the default test to the DHCP test.	2006-07-20 02:51:52 +00:00
Michael Brown	00a1f000b1	Added dhcp_ipv4_option() and friends. Added test code to configure the interface for IPv4 after DHCP.	2006-07-20 02:49:59 +00:00
Michael Brown	6a0b4c9772	Free up any allocated options if we fail	2006-07-20 02:25:39 +00:00
Michael Brown	764cb41456	Document memory ownership.	2006-07-20 02:23:42 +00:00
Michael Brown	7ca1bb0fbe	Now successfully negotiates the whole DHCPDISCOVER/OFFER/REQUEST/ACK cycle. :)	2006-07-20 02:19:06 +00:00
Michael Brown	30d9bcdc6e	Rename unwieldy function	2006-07-20 00:24:25 +00:00
Michael Brown	9ad5cede96	Set DHCP_MESSAGE_TYPE option within the main options block. This doesn't seem to be required by the RFCs, but at least ISC dhcpd and ethereal refuse to recognise it otherwise.	2006-07-20 00:18:50 +00:00
Michael Brown	881b90e82c	Packets without a DHCP_MESSAGE_TYPE option are probably just BOOTP packets.	2006-07-20 00:03:25 +00:00
Michael Brown	29b358dd39	conn->local_port is now network-endian; do not swap when comparing against value in header. Temporarily disable RX checksumming; it's broken and is holding up work on higher-layer protocols .	2006-07-20 00:03:01 +00:00
Michael Brown	36c94eae78	Clarify hexiness of header length	2006-07-20 00:01:50 +00:00
Michael Brown	2c0eb6eb1d	Correct TCP/IP checksum generation.	2006-07-19 23:38:05 +00:00

Nikhil Chandru Rao	13dbf5494d	Minor edits	2006-07-19 21:05:58 +00:00
Michael Brown	224529d8dd	Now capable of sending what, to me, looks like a valid DHCPDISCOVER (apart from the bad UDP checksum).	2006-07-19 20:50:50 +00:00
Michael Brown	a38010fb0e	Make udp_send() call udp_sendto(), rather than vice-versa.	2006-07-19 20:38:49 +00:00
Michael Brown	7c84b74185	A small but very critical bug.	2006-07-19 20:16:46 +00:00
Michael Brown	82f3295794	Use more standardised format specifiers in debug messages (e.g. %p for a pointer).	2006-07-19 18:45:18 +00:00
Michael Brown	ab633f6a73	Reserve space for lower-layer headers when allocating packet buffer. Use pkb_available() rather than pkb_len() (which will always return 0 on a freshly allocated buffer). udp_send() should assume that the buffer has already been allocated.	2006-07-19 18:21:30 +00:00
Michael Brown	6858b14a34	Add pkb_available()	2006-07-19 18:16:48 +00:00
Michael Brown	e8daeb62b1	Eliminate confusion between functions that return pointers and functions that return status codes. Zero the DHCP packet buffer before creating the options structures inside it.	2006-07-19 18:11:31 +00:00
Michael Brown	3369f93036	Add block identification to debug messages	2006-07-19 17:58:27 +00:00

Michael Brown	317b962b65	Proof of concept: transmit a single DHCPDISCOVER and dump out any parsed DHCP responses.	2006-07-19 17:32:13 +00:00
Michael Brown	76070cd226	Added missing prototype	2006-07-19 17:29:18 +00:00
Michael Brown	16fc9858db	Beginnings of DHCP protocol implementation	2006-07-19 17:01:06 +00:00
Michael Brown	a7011edfd4	Add net/udp	2006-07-19 17:00:40 +00:00
Michael Brown	bf0cdd42cf	Add some DHCP options that we are likely to use	2006-07-19 17:00:32 +00:00

Nikhil Chandru Rao	ab577e1a3a	The following edits were made: \ 1. Updated UDP send data code\ 2. Corrected internet checksum\ 3. Moved udp_buffer() and udp_buflen() to udp.c from udp.h	2006-07-19 16:25:23 +00:00
Michael Brown	b8d619e822	Added macros for generating static DHCP options	2006-07-19 16:16:51 +00:00
Michael Brown	254fe6e00e	Split DHCP packet creation into two parts: creating the basic packet structure, and populating it with options. This should allow us to use the same basic options list for both DHCPDISCOVER and DHCPREQUEST, plus making it much easier to set the non-constant parameters (e.g. requested IP address) in request packets.	2006-07-19 12:12:45 +00:00
Michael Brown	e40ebb67de	Allow for calling find_dhcp_option() with "options" set to NULL, in order to search through all registered option blocks. Move some static inlines that are likely to be used frequently into dhcpopts.c as normal functions, to save space.	2006-07-19 11:05:38 +00:00
Michael Brown	7ab29b0bfe	This file breaks "make blib"; please find a way to avoid doing this.	2006-07-17 19:19:17 +00:00
Derek Pryor	e71098a652	The first packet (ClientHello Handshake) can be constructed and is accepted	2006-07-17 16:38:20 +00:00
Michael Brown	6c01d3bb95	Fix creation of the htype field; the ll_proto field from which it is derived is a 16-bit big-endian field, but htype is only 8 bits wide.	2006-07-17 13:07:14 +00:00
Michael Brown	35b0233baa	Tidy up hex_dump() output.	2006-07-17 13:04:29 +00:00
Michael Brown	b24947f0c0	Add sketch code to reassemble a DHCP packet from our internal "everything is a DHCP option" data structures. We need this code in order to be able to return a DHCP packet to a PXE NBP which reflects options from our multiple sources (e.g. NVS and DHCP server). This is expensive, but necessary. Having paid this cost, we may as well try to use the same code to generate our DHCP request packets, since the process is similar.	2006-07-17 12:47:22 +00:00
Michael Brown	12da7ea475	Add (untested) code for parsing a received DHCP packet and constructing a DHCP options block from the contents.	2006-07-15 19:24:55 +00:00
Michael Brown	19e8b41562	Add code to modify DHCP option values within a block.	2006-07-13 20:49:04 +00:00

Nikhil Chandru Rao	8de630c62b	Removing net/interface.c and include/gpxe/interface.h	2006-06-29 06:51:11 +00:00
Michael Brown	51d62d1a3c	Provide a mechanism for returning the encapsulator as well as the encapsulated option; this will be needed for modifications to the options block.	2006-06-28 18:59:54 +00:00
Nikhil Chandru Rao	c9ea710930	Renamed net/interface.c and include/gpxe/interface.h to net/tcpip_if.c and include/gpxe/tcpip_if.h respectively. Made changes in the other files.	2006-06-28 15:43:08 +00:00
Michael Brown	291f072b82	Add priority mechanism	2006-06-28 13:48:02 +00:00

Dan Lynch	d8b51332c6	typo in macro fixed	2006-06-28 11:53:41 +00:00
Dan Lynch	ba2bfd54ed	- modified length of password string to match visible field length - value of n passed to wgetnstr should now be equivalent to output from strlen (i.e. length excluding NUL-terminating character)	2006-06-28 11:52:30 +00:00
Dan Lynch	f9887c3f0f	started on ANSI sequence processing	2006-06-28 11:50:02 +00:00
Dan Lynch	c29c868475	- implemented cursor retreat function (_wcursback) as a core function - reimplemented cleaner wgetnstr - fixed wdelch for use with _wcursback	2006-06-28 11:48:40 +00:00
Nikhil Chandru Rao	6e2c97b0c0	Added ipv4_pseudo_header structure	2006-06-28 09:59:27 +00:00

Dan Lynch	2b15084388	- first check-in for mucurses_test.c - added mucurses_test.c build targets	2006-06-27 17:31:01 +00:00
Michael Brown	0bcaa8a21f	First stab at DHCP option handling in a way that will allow us to have multiple option sources (e.g. multiple DHCP replies, non-volatile storage etc.)	2006-06-27 17:24:07 +00:00
Dan Lynch	7f4cfe4a84	- put in the screen initialisation stuff and clear the screen...	2006-06-27 17:18:11 +00:00
Dan Lynch	11e280670d	- works with test ansi tty, but will need a rethink when we start getting key_ codes instead	2006-06-27 17:15:34 +00:00
Dan Lynch	f78fa3c59d	- working basic ansi termnal extension for mucurses	2006-06-27 17:11:57 +00:00

Dan Lynch	5d2f39bbc2	added placeholder SRCDIRS entry for mucurses	2006-06-27 10:31:42 +00:00
Dan Lynch	1c87d54bb8	- recoded wgetch and wgetnstr for greater more efficiency - wgetch now includes non, part and full blocking read support	2006-06-27 10:24:40 +00:00
Michael Brown	35557914e3	Simplify ipv4_tx() by not having a separate "source" variable now that we are constructing the IP header ourselves. Formatting fix-ups (80 column limit is mandatory!)	2006-06-26 16:10:34 +00:00
Michael Brown	b49de73950	Factorise out common code	2006-06-26 16:01:24 +00:00

Dan Lynch	6fc723c294	- added doxygen @file header - no longer depends on slk	2006-06-21 10:35:46 +00:00
Dan Lynch	d77120541a	- added doxygen @file header	2006-06-21 10:31:59 +00:00

Michael Brown	15397db2b4	Placeholder	2006-06-17 23:34:48 +00:00
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.	2006-06-17 23:20:54 +00:00
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.	2006-06-17 22:36:27 +00:00
Michael Brown	8aeead7c1c	Remove dependency on arptable[] (which is no longer used).	2006-06-16 14:48:31 +00:00
Michael Brown	d393e61d8a	Temporary hack to work around the "TX overflow" problem in the interim period before updating to the new driver API (which can cope with having TX packets in progress).	2006-06-16 14:38:16 +00:00
Michael Brown	52de4935f9	Add 4 bytes to maximum frame length to allow for the frame checksum. (This actually matters once you try using TCP, because you will receive full-sized frames.)	2006-06-16 14:30:41 +00:00
Michael Brown	7c76791730	Improve debugging output for legacy wrapper	2006-06-16 14:27:04 +00:00

Michael Brown	968501e323	For consistency	2006-06-16 13:17:40 +00:00
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.	2006-06-16 13:16:59 +00:00
Michael Brown	bbd9e28061	Simplify TX datapath.	2006-06-16 00:19:46 +00:00
Michael Brown	cce2e47ff4	Added iSCSI boot test code	2006-06-14 17:00:25 +00:00
Michael Brown	3b51c719d3	Generalise three-wire interface to generic SPI interface. Update rtl8139 driver to instantiate an SPI interface with a three-wire device attached.	2006-06-14 00:22:50 +00:00
Michael Brown	ab4f96e525	Move per-transition delays from generic bit-bashing layer to i2c layer (since SPI bit-bashing will require different delay semantics).	2006-06-14 00:20:35 +00:00
Michael Brown	714641ae6d	Translate between "0 = success" and "0 = failure" call standards.	2006-06-14 00:18:13 +00:00
Michael Brown	51a36f1cfb	Change read_bit() to return 0 or -1UL, rather than 0 or 1.	2006-06-12 19:29:50 +00:00
Michael Brown	2e49441535	Updated debug message to reflect change in data structure.	2006-06-12 01:10:08 +00:00
Michael Brown	2138db36ca	Add "addr32" required explicitly by older gas.	2006-06-12 01:07:43 +00:00

Michael Brown	55bb40c39a	Fix typo	2006-06-11 01:55:12 +00:00
Michael Brown	df4b503a8c	Added null trap code for debugging. (Must be included by adding --nulltrap to the make target at the moment.)	2006-06-11 01:48:29 +00:00
Michael Brown	7ce44f7480	Update to use the generic i2c bit-bashing code.	2006-06-11 00:57:38 +00:00
Michael Brown	3ed40686c9	Added bit-bashing i2c interface code	2006-06-11 00:57:00 +00:00
Michael Brown	476d02051f	Windows Server 2003 sulks if we feed it an empty region in base memory as a result of our memory map editing, so strip out any empty regions.	2006-06-09 12:20:03 +00:00
Michael Brown	6fd1bd0510	Added missing check-in	2006-06-09 10:19:17 +00:00
Michael Brown	e90b64d625	Added sketch of bit-bashing interface common code	2006-06-08 19:47:09 +00:00
Michael Brown	17eea9f933	Fix bug with >256 cylinders. Allow our functions to return a non-zero, non-error status (since the INT 13 Extensions Check has to return the API version in the register that is otherwise always used for the error code). Report a non-zero API version from the INT 13 Extensions Check; GRUB now uses extended reads.	2006-06-08 19:28:08 +00:00
Dan Lynch	ad1aca0634	- separated curses.c out into separate source files to optimise library use later on - some small mods to existing functions	2006-06-08 17:23:37 +00:00
Michael Brown	1697c78848	Legacy drivers cannot cope with multiple active devices.	2006-06-08 15:18:27 +00:00
Michael Brown	fdf62528ca	It's astonishing how long really fundamental bugs can survive without being noticed...	2006-06-08 15:06:09 +00:00
Michael Brown	191a906338	Fix some remarkably obvious mistakes in pcidirect.h	2006-06-08 14:57:04 +00:00
Michael Brown	763b7e2ef9	We now have just romprefix, rather than having isaprefix and pciprefix	2006-06-06 15:41:21 +00:00
Michael Brown	ef37f78cbe	Cut out almost all the optional code paths, drastically simplifying the flow of control through this code. We now always add PCI and PnP headers even for ISA ROMs; there's no harm in doing so. UNDI loader is still missing.	2006-06-06 15:33:39 +00:00
Michael Brown	e7eca7b7cb	Code segment may not be writable; create the temporary pointer to the GDT on the stack.	2006-06-06 15:30:28 +00:00
Michael Brown	46253ba618	Calculate _rom_size for the ROM prefix	2006-06-06 15:29:39 +00:00
Michael Brown	8d0c5f3302	Use byte 6 for the checksum, rather than byte 5. (Byte 5 may be part of the jmp instruction).	2006-06-06 15:29:14 +00:00
Michael Brown	02df45352c	Force pci.o to be included. Print warning message at probe time.	2006-06-05 16:17:52 +00:00
Michael Brown	754cfdfcf4	Legacy drivers will not pad when necessary	2006-06-05 16:10:36 +00:00
Michael Brown	7826de3f7e	PNIC doesn't auto-pad.	2006-06-05 16:10:14 +00:00
Michael Brown	286bf68faf	Added a very quick and dirty compatibility layer, to allow not-yet-updated drivers to at least function.	2006-06-05 15:45:21 +00:00
Michael Brown	c3e41e6fd1	Added soon-to-be-requisite missing include.	2006-06-05 15:41:22 +00:00
Dan Lynch	34cfbf55a4	- added most slk functions	2006-06-05 15:03:11 +00:00
Michael Brown	d78581297b	Improve tcpdump legibility.	2006-06-01 19:23:52 +00:00
Michael Brown	6ab4b99f41	Quick hack to avoid trying to use an uninitialised net device.	2006-06-01 15:53:05 +00:00
Michael Brown	48fb6c6dc2	Updated retry timer mechanism to incorporate smoothed RTT estimation. AoE now uses the retry timer mechanism.	2006-06-01 14:33:52 +00:00
Michael Brown	50415b3aca	Make DBG_DISCARD correct	2006-06-01 12:11:09 +00:00
Michael Brown	1f394c2f7c	Backing out last change; no immediate plans to make the whole block-device layer asynchronous, so keeping the sync/async boundary within aoedev.c seems cleanest for now.	2006-06-01 11:14:59 +00:00
Michael Brown	d6866202f9	Until we have a functioning UDP stack and PXE API again, there's not much point trying to use the old boot sequence. Replaced with a call to the AoE demo code, so that people can at least build and try something useful.	2006-06-01 11:07:31 +00:00
Michael Brown	d21fc3610f	Added sample AoE test code to tree	2006-06-01 11:05:36 +00:00
Michael Brown	f6d20bb0f4	Put in a method to get the MAC address for the AoE target. (It's not elegant, but it works).	2006-05-31 19:12:17 +00:00
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).	2006-05-31 18:57:11 +00:00
Michael Brown	cf96d325d8	Missing from previous checkin. This is the core portion of the async I/O interface.	2006-05-31 18:45:43 +00:00
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()).	2006-05-31 14:34:17 +00:00
Michael Brown	73a449e96b	Added drivers/ata directory (forgot to check this in previously).	2006-05-31 14:31:48 +00:00
Michael Brown	552b4a178e	One bit of an ASCII character can make a big difference.	2006-05-29 21:00:00 +00:00
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.	2006-05-29 14:55:07 +00:00
Michael Brown	6541338897	Handle multi-sector reads by splitting them into subcommands.	2006-05-29 08:25:31 +00:00
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! :)	2006-05-28 23:29:43 +00:00
Michael Brown	6f998cecb3	Use separate data-in and data-out buffers. Increase code simplicity at the expense of around 64 bytes.	2006-05-28 23:26:42 +00:00
Michael Brown	6d6252067f	Add ETH_P_AOE	2006-05-28 21:47:52 +00:00
Michael Brown	35b04b1514	Tidy up comment	2006-05-28 14:40:04 +00:00
Michael Brown	041a04335e	Fixed assembly on old versions of gas	2006-05-28 14:21:29 +00:00
Michael Brown	f743de4858	Added tcp_kick(). This speed up LILO and GRUB booting by almost two orders of magnitude.	2006-05-27 19:01:20 +00:00
Michael Brown	cd3ecac809	Avoid causing TX overflow on small TX queues.	2006-05-27 13:55:36 +00:00
Michael Brown	70ef6dbb7c	Rewrote to use the new net driver API, the updated PCI API, and the generic three-wire serial device support for EEPROM access.	2006-05-27 13:45:14 +00:00
Michael Brown	69b1f24a97	I have no idea how this ever worked before.	2006-05-27 13:43:56 +00:00
Michael Brown	6c50564724	Make PKB_ZLEN the minimum possible size of packet buffer (to allow for hardware that can't autopad).	2006-05-27 13:39:45 +00:00
Michael Brown	1dbafa8950	Tidied up debugging messages	2006-05-27 13:38:49 +00:00
Michael Brown	aa2468babe	Added abstraction layer for a three-wire serial device (e.g. the EEPROM used on RTL8139 cards).	2006-05-26 15:39:24 +00:00
Michael Brown	9f86754f90	Updated to work with libprefix.	2006-05-25 22:04:47 +00:00
Michael Brown	29340d7728	Documented the fact that the prefix can prot_call(main) without worrying about its stack being destroyed during the Etherboot run.	2006-05-25 22:04:17 +00:00
Michael Brown	0479e9f541	relocate.o is now dragged in by the objects that require it; there is no need for a CONFIG_RELOCATE.	2006-05-25 01:34:13 +00:00
Michael Brown	3204a1e941	Removed some obsolete INIT_XXX constants.	2006-05-25 01:09:06 +00:00
Michael Brown	d82f71efd0	Also hide base memory region from E820 map.	2006-05-25 00:10:58 +00:00
Michael Brown	89da833c5d	init_librm() and prot_call() are now real-mode far calls. install() now calls relocate(), moves the protected-mode code to the new location, and calls hide_etherboot().	2006-05-25 00:06:45 +00:00
Michael Brown	4d81b48504	Has been obsolete for a while.	2006-05-25 00:04:37 +00:00
Michael Brown	1966945a5d	Update relocate() to work with get_memmap(). Change semantics; relocate() now just finds a suitable location; it doesn't actually perform the relocation itself. Code in libprefix does the copy in flat real mode.	2006-05-25 00:04:13 +00:00
Michael Brown	f939ff7cb5	Fix printf format warning error	2006-05-25 00:02:27 +00:00
Michael Brown	3bd3c13c7b	Why should pushal/popal put the registers on the stack in a logical order?	2006-05-25 00:01:46 +00:00
Michael Brown	dd75965057	Typo.	2006-05-25 00:00:53 +00:00
Michael Brown	e4f8d6eed7	Add a "count" field to struct memory_map.	2006-05-25 00:00:30 +00:00
Michael Brown	986f6ffff1	Define a struct memory_map with a fixed number of entries, rather than requiring each caller to decide how many entries it wants to permit.	2006-05-24 14:41:27 +00:00
Michael Brown	edcf89e2b0	Remove the automatic segment register save and restore; most users of REAL_CODE() don't need it.	2006-05-24 14:11:36 +00:00
Michael Brown	02cf755f3f	Removed REAL_EXEC(); there is no longer any code using it.	2006-05-24 14:10:15 +00:00
Michael Brown	103aff3ae2	Added potentially required "\n\t" on the end of asm_code_str	2006-05-24 14:06:28 +00:00
Michael Brown	190276a8b6	NBI is due for removal	2006-05-24 13:53:35 +00:00
Michael Brown	52125e158c	Will be replaced with a block-device implementation.	2006-05-24 13:52:46 +00:00
Michael Brown	8110f9b082	Updated to REAL_CODE()	2006-05-24 13:50:40 +00:00
Michael Brown	595f161b51	Updated to REAL_CODE(). int13_boot() now does its own segment register save and restore, ready for the removal of segment register restoration from the libkir generic code.	2006-05-24 13:48:16 +00:00
Michael Brown	e8550035af	Updated to REAL_CODE()	2006-05-24 13:28:39 +00:00
Michael Brown	c4d688c005	Updated to REAL_CODE().	2006-05-24 13:24:22 +00:00
Michael Brown	04d6005d77	Update to REAL_CODE()	2006-05-24 12:45:50 +00:00
Michael Brown	6631f46999	Updated to REAL_CODE().	2006-05-24 12:32:57 +00:00
Michael Brown	53935e9dc6	Set carry flag before calling INT 15,e801 and INT 15,e820. Ignore carry flag for INT 15,88; the Ralf Brown interrupt list says that CF is unreliable for this call.	2006-05-24 12:19:16 +00:00
Michael Brown	7a53d07027	Split out REAL_CODE() from REAL_EXEC(), preparatory to removing REAL_EXEC completely.	2006-05-24 09:51:04 +00:00
Michael Brown	83d80d9e79	Remove references to obsoleted REAL_CALL from documentation.	2006-05-24 09:16:48 +00:00
Michael Brown	3b525385af	Removed REAL_FRAGMENT and REAL_CALL, and left just REAL_EXEC (which is the only one we actually use). This allows REAL_EXEC fragments to contain proper references to constraints (e.g. "%w0"), rather than having to force the use of specific registers. Note that the "num_constraints" parameter is now completely obsolete, and that we can probably reduce the syntax to something like __asm__ __volatile__ ( REAL_CODE ( "asm statements" ) : output constraints : input constraints : clobber ); which would look much more natural, and avoid the need to always specify a clobber list. Add userptr_t to libkir.h, to allow it to at least compile.	2006-05-24 09:14:44 +00:00
Michael Brown	77a65075a6	Replaced memsizes.c with smaller memmap.c, taking advantage of __data16, and creating a memory map that's easier to work with than the E820 map.	2006-05-24 01:37:46 +00:00
Michael Brown	5e80847827	Code to install the new E820 mangler (which doesn't require copying down to base memory, since it is now in the base-memory-resident .text16 section).	2006-05-23 23:47:05 +00:00
Michael Brown	897313007b	Add __{text,data}16_array, since there's no way I can see to make the usual __{text,data}16 trick work with arrays. gcc seems to accept the __asm__ ( asmlabel ) only after the [] of the array declaration, not before.	2006-05-23 23:42:45 +00:00
Michael Brown	5ec2b2c251	Cope with regions bigger than 4GB. We now split e820 regions around ourselves, rather than just truncating the e820 region. This avoids the worst-case scenario of losing all memory over 4GB. It's more important to get the memory map right now that we're expecting to still be loaded when the OS starts in several situations (e.g. Linux with UNDI driver, any OS with iSCSI/AoE boot, etc.).	2006-05-23 23:33:37 +00:00
Dan Lynch	bef8874842	- implemented printw (formatted string output, a la printf) - implemented hline/vline (part of wborder family) - screen cursor now relocates at same time as window cursor when restoring after a non-wrapping function	2006-05-22 17:03:41 +00:00
Michael Brown	84a493b88d	Allow vcprintf() to be called by external code such as the curses library. Also trim another eight bytes from vsprintf.o. :)	2006-05-22 15:41:01 +00:00
Dan Lynch	f778500739	- fixes to _wputch to get positioning and wrap working properly - fixes to wborder (same) - addition of a few minor functions	2006-05-22 13:10:19 +00:00
Michael Brown	95956443e1	Fixed debug code	2006-05-21 16:04:41 +00:00
Michael Brown	9dfb9d84b4	Made the LBA48 example clearer.	2006-05-21 16:02:38 +00:00
Michael Brown	80958ff69c	Added (untested) support for ATA devices. This code should be generic enough to support both real IDE chipsets and AoE.	2006-05-21 16:01:23 +00:00
Michael Brown	ca2519cea3	Refactored to reduce code size; now down from 1304 to 1105 bytes. Tidied up debug messages; the log now contains one line per INT 13 operation, looking like INT 13,08 (80): Get drive parameters INT 13,02 (80): Read: C/H/S 0/47/14 = LBA 0xb9e <-> 1084:0000 (count 106)	2006-05-20 15:33:32 +00:00
Michael Brown	af4aacb978	Added missing @file block	2006-05-20 13:25:07 +00:00
Michael Brown	4d0a0f822d	Use insb/outsb; it's marginally faster.	2006-05-20 12:28:44 +00:00
Michael Brown	402ba15c64	READ CAPACITY (16) turns out to be an optional command (even though READ(16) is mandatory); we must use READ CAPACITY (10) first and then use READ CAPACITY (16) if the READ CAPACITY (10) returns "out of range".	2006-05-19 18:54:38 +00:00
Michael Brown	444b885a7d	Add EOVERFLOW==ERANGE	2006-05-19 18:53:12 +00:00
Michael Brown	b9cbae58fa	Expert advice tells me that we do have to explicitly state the options even when we want to use the defaults.	2006-05-19 17:50:49 +00:00
Dan Lynch	acf572905c	- made some of the bit shifting attribute access simpler (in my mind) - added extern declarations for global vars - removed comments from static inlines (too time consuming to do them all, considering all so far have been due to the ridiculous amount of redundancy within the API spec) - removed a few more extern func decls for funcs that cannot be implemented at this time	2006-05-19 16:22:10 +00:00
Dan Lynch	d166dc57ab	- made _wputch wrap lines as well as cols (wraps back to line 0, as we have not way to scroll...) - implemented color_content, wborder, wblrtobot, wclrtoeol, wcolor_set and several small functions - added rest of expected global variables	2006-05-19 16:18:08 +00:00
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).	2006-05-19 15:06:51 +00:00
Michael Brown	0ab92faedb	Use typeof(sizeof(...)) to define a size_t. This stops gcc complaining about format errors for %zX arguments.	2006-05-19 14:51:59 +00:00
Michael Brown	c69c1ec540	Documented login parameters that we negotiate.	2006-05-19 00:31:42 +00:00
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.	2006-05-19 00:20:08 +00:00
Michael Brown	b531bd2bda	All uses iscsi_state were removed some time ago; removing the declaration.	2006-05-18 21:38:16 +00:00
Michael Brown	53b682f3a2	Re-enable -Wformat, since our printf() is now more standards-conformant.	2006-05-18 21:23:38 +00:00
Dan Lynch	2814681d20	all window primitives implemented	2006-05-18 17:51:19 +00:00
Michael Brown	813a052dc3	Set ErrorRecoveryLevel=0 (we don't want to have to handle it).	2006-05-17 17:41:50 +00:00
Michael Brown	61d7b8a5ef	Added missing drivers/scsi	2006-05-17 17:31:18 +00:00
Michael Brown	a4143e8c87	Split debug functions out into core/debug.c, so that they can be automatically linked in on demand. Corrected warnings in misc.c. strtoul() really should be unsigned long strtoul ( const char p, const char *endp, int base ) but such is not the ANSI standard.	2006-05-17 17:16:24 +00:00
Michael Brown	6b6096d28b	Strip down i386 PCI configuration space I/O to the bare minimum. A typical build will now include 880 bytes of PCI support code, compared to 2327 bytes in Etherboot 5.4. (There is a slight cost of around 5 extra bytes per access to a non-constant config space address; this should be an overall win. Driver-specific accesses will usually be to constant addresses, for which there is no additional cost.)	2006-05-17 01:12:11 +00:00
Michael Brown	15ee09ed10	Restructured PCI subsystem to fit the new device model. Generic PCI code now handles 64-bit BARs correctly when setting "membase"; drivers should need to call pci_bar_start() only if they want to use BARs other than the first memory or I/O BAR. Split rarely-used PCI functions out into pciextra.c. Core PCI code is now 662 bytes (down from 1308 bytes in Etherboot 5.4). 284 bytes of this saving comes from the pci/pciextra split. Cosmetic changes to lots of drivers (e.g. vendor_id->vendor in order to match the names used in Linux).	2006-05-16 15:12:06 +00:00
Michael Brown	fcdab6299c	Missed a reference to heap.h.	2006-05-16 15:01:26 +00:00
Michael Brown	0afa9db2de	Tear out old heap code, replace with code that simply allocates memory for use by malloc(). This breaks the image-loading code (which previously used the heap to allocate the buffer for downloading the image), but that's not a major concern since I'm going to tear out all the image formats within the next couple of days anyway. Byebye, NBI! :)	2006-05-16 15:00:36 +00:00
Michael Brown	689218618f	Fix typo	2006-05-16 14:42:43 +00:00
Michael Brown	441189c6f8	Kill off the "all devices are boot devices" idea	2006-05-16 14:42:15 +00:00
Michael Brown	7cd0390013	Add list_for_each_entry_safe.	2006-05-16 14:14:31 +00:00
Michael Brown	ceba6ecb75	Added generic device model.	2006-05-16 14:10:21 +00:00
Michael Brown	6b514393d3	Change movetoyx(), putc() and getc() to methods of the screen.	2006-05-15 09:51:18 +00:00
Dan Lynch	a2799051b0	fixed build error (danjlynch, repeat: this is not perl, this is not perl...)	2006-05-15 09:34:27 +00:00
Dan Lynch	dccc6aed3a	lightweight xcurses implementation for etherboot (Michael made me do it...)	2006-05-15 09:29:48 +00:00
Michael Brown	295e11b2b0	Add INT 13,41 (extensions installation check). LILO's MBR now uses linear calls to load the MS-DOS boot sector in my test setup.	2006-05-14 23:46:28 +00:00
Michael Brown	f25731d08f	Split "iSCSI as a SCSI device" out from "iSCSI as a TCP protocol".	2006-05-14 23:29:16 +00:00
Michael Brown	29fb77b0a4	Fix a couple of minor typos.	2006-05-14 18:17:29 +00:00
Michael Brown	6e42cb95bd	Also capture INT 19 as a failure path, to allow for boot sectors that don't conform to BBS (e.g. the one created by mkdosfs).	2006-05-14 14:13:55 +00:00
Michael Brown	4435667a00	Add int13_boot(), to allow booting from INT 13 emulated drives.	2006-05-14 13:44:47 +00:00
Michael Brown	b4f941b257	Specify attributes on .text16.	2006-05-14 13:39:27 +00:00
Michael Brown	eb6b8e8d70	Handle the '"%c", 0' case correctly.	2006-05-14 11:55:30 +00:00
Michael Brown	efd6281a35	Correctly handle zero-length buffers.	2006-05-14 11:18:42 +00:00
Michael Brown	25f5d114a0	Updated documentation. Shaved around 100 bytes off vsprintf.o. It's now 50 bytes smaller than the old implementation and provides much more conformant semantics, including the ability to return the number of characters that would have been printed to the string had the buffer been big enough. (iSCSI needs this functionality).	2006-05-14 03:31:20 +00:00
Michael Brown	2421723a15	Rewrote printf and friends to better support standard C semantics.	2006-05-14 02:51:55 +00:00
Michael Brown	f99e7a375e	At least cope with "%llx" by reading the correct-sized va_arg from the stack, even if we don't yet print it out. At some point, vsprintf() needs to be fixed up so that it can correctly cope with limited-sized buffers (i.e. vsnprintf), long longs, and standard format specifiers (e.g. "%04x"). We should also remove the special types (MAC addresses and IP addresses). This would then enable us to use gcc's ability to type-check printf format strings.	2006-05-13 11:50:52 +00:00
Michael Brown	21493646c2	Moved to net/tcp/iscsi.c.	2006-05-13 11:45:49 +00:00
Michael Brown	5080668704	Provide access to rm_cs and rm_ds from protected-mode code.	2006-05-13 11:45:31 +00:00
Michael Brown	dc8d429ec6	Provide a global counter for the number of interrupts hooked.	2006-05-13 11:44:53 +00:00
Michael Brown	63499e9cfd	Allow re-entrancy and provide a global counter of the number of interrupts hooked.	2006-05-13 11:44:11 +00:00
Michael Brown	d822b3d4cd	Define BIOS data segment in bios.h	2006-05-13 11:43:07 +00:00
Michael Brown	a27defa483	Add flag definitions.	2006-05-13 11:42:07 +00:00
Michael Brown	d2c22ec9bb	Add INT 13 emulation layer (which provides an interface to gPXE block devices).	2006-05-13 11:41:36 +00:00
Michael Brown	1ad72e0e79	Add 64-bit byte-swapping operations.	2006-05-13 11:40:39 +00:00
Michael Brown	5009f8d6a2	Provide a SCSI device interface to the iSCSI protocol	2006-05-13 11:39:46 +00:00
Michael Brown	f33f01c126	Defined SCSI device interface, and added SCSI block device implementation.	2006-05-13 11:37:50 +00:00
Michael Brown	8638a5e471	Defined a block device interface.	2006-05-13 11:36:30 +00:00
Michael Brown	1838b58c3f	Add drivers/block and arch/i386/interface/pcbios	2006-05-13 11:35:29 +00:00
Michael Brown	568cad0ddc	(Redoing check-in lost by SourceForge's failure.)	2006-05-13 11:30:03 +00:00
Michael Brown	8a229a16f6	(Redoing check-in lost by SourceForge's failure.) Moved to net/	2006-05-13 11:24:25 +00:00
Michael Brown	847f38f4ac	(Redoing check-in lost by SourceForge's failure.) Add method for hooking real-mode interrupt vectors.	2006-05-13 11:19:06 +00:00
Michael Brown	f7b963da51	(Redoing check-in lost by SourceForge's failure.) Use .text16.data section with "aw" attributes, to avoid section type conflicts when placing both code and data into .text16. Add __from_{text16,data16}.	2006-05-13 11:11:55 +00:00
Michael Brown	97d265f8dc	(Redoing check-in lost by SourceForge's failure.) Avoid optimisation errors under -fstrict-aliasing.	2006-05-13 11:10:24 +00:00
Michael Brown	fdb983d473	Preserve the whole of %esp across prot_call(). We have to split this between the low half stored in the static variable rm_sp, and the high half stored on the prot_call() stack, because: Just using the stack would screw up when a prot_call()ed routine executes a real_call(); it would have no way to find the current top of the RM stack. Extending rm_sp to rm_esp would not be safe, because the guarantee that rm_sp must return to the correct value by the time an external real-mode call returns applies only to %sp, not to %esp.	2006-05-06 19:44:23 +00:00
Michael Brown	f8e087767b	Allow access to variables in .text16 as well as .data16. Chained interrupt vectors, for example, will be easiest to handle if placed in .text16.	2006-05-06 18:57:31 +00:00
Michael Brown	c10d1aa9d7	Preserve GDT across prot_call().	2006-05-06 18:52:27 +00:00
Michael Brown	dcc1b0054e	This line should not have been checked in	2006-05-04 23:22:42 +00:00
Michael Brown	832807726a	Add infrastructure to support access to .data16 (and .text16) variables from protected-mode code. Set up %ds to point to .data16 in prot_to_real, so that code specified via REAL_EXEC() and friends can access variables in .data16. Move most real-mode librm variables from .text16 to .data16.	2006-05-04 23:14:06 +00:00
Michael Brown	f4429533a6	Added methods for efficiently declaring and accessing variables in .data16. librm will need to supply "char *data16", i.e. the virtual address of the start of .data16.	2006-05-04 17:00:20 +00:00
Michael Brown	f8f75cef5b	BSS is now zeroed by libprefix (along with the otherwise non-zeroable portions such as the stack) during the installation process. init_fns() are called from main(). We need to think about initial control flow some more.	2006-05-02 21:10:45 +00:00
Michael Brown	cc23057b59	Typo	2006-05-02 21:09:29 +00:00
Michael Brown	10c28a51bd	Create two easy-to-use entry points in libprefix: install and install_prealloc. I think these will suffice for all the 16-bit prefixes.	2006-05-02 20:51:07 +00:00
Michael Brown	9e1dd6402d	<name>_size variable is no longer needed, since we don't copy the code. However, it's worth adding a .size directive so that objdump reports the correct sizes for the code fragments.	2006-05-02 16:38:46 +00:00
Michael Brown	9fcded3d23	Towards a(nother) new real-mode infrastructure, in which we take advantage of the fact that we have to have a permanently-resident block in base memory.	2006-05-02 15:41:21 +00:00
Michael Brown	8f62b39c03	Move stack out to separate object, so that having a stack doesn't drag in setup.S.	2006-05-02 14:57:48 +00:00
Michael Brown	5463169c1a	Verified as working	2006-05-02 14:04:21 +00:00
Michael Brown	d081d65d48	This should be much more elegant: we use flat real mode for the highmem data, so decompress16 will be able to unpack blocks bigger than 64kB.	2006-05-01 22:35:19 +00:00
Michael Brown	cc8821a443	Checking in because I don't want to lose this rather neat code for running the decompresser in 16:16 protected mode using the real-mode stack. However, there's an even simpler way to do it...	2006-05-01 21:26:44 +00:00
Michael Brown	2462047128	Typo	2006-04-30 18:19:39 +00:00
Michael Brown	9e1becaf8a	Merge TCP aborted(), timedout() and closed() methods into a single closed() method with a reason code.	2006-04-30 16:59:45 +00:00
Michael Brown	8afb6303fb	Half-way tidy	2006-04-30 15:23:29 +00:00
Michael Brown	04b6a1e004	Make all TCP methods optional; at least FTP data is a read-only connection and so legitimately ignores acked() and senddata().	2006-04-30 13:20:40 +00:00
Michael Brown	aec0e127d2	Proof-of-concept FTP implementation	2006-04-30 12:02:07 +00:00
Michael Brown	a42092d2a0	Add a temporary snprintf, so that safely-written code can at least compile, even if it won't yet be safe.	2006-04-30 12:01:31 +00:00
Michael Brown	8df7e74990	Fix up prototype of strtoul() to match POSIX.	2006-04-30 11:45:38 +00:00
Michael Brown	01bd78d62a	Created net/tcp and moved hello.c there	2006-04-30 09:34:11 +00:00
Michael Brown	7af478b30d	Make tcp_connect() void; it will eventually have no failure case.	2006-04-30 02:13:52 +00:00
Michael Brown	9c9208a132	Put the TCP connection periodic processing in tcp.c, where it belongs.	2006-04-30 02:08:42 +00:00
Michael Brown	178b0a7e5e	Consistency	2006-04-30 01:35:01 +00:00
Michael Brown	592a5a99c8	Moved uIP and tcp.c from proto/ to net/	2006-04-30 01:16:37 +00:00
Michael Brown	352bf1bda2	Move init.h to gpxe/init.h.	2006-04-30 01:08:52 +00:00
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.	2006-04-29 17:17:43 +00:00
Michael Brown	23c494d14e	Added basic code for implementing co-operative multitasking. Yes, you really can do it in 65 bytes.	2006-04-29 16:42:09 +00:00
Michael Brown	5fe31f1014	Give uIP a static IP address for proof-of-concept testing	2006-04-28 14:15:21 +00:00
Michael Brown	129c6c3968	Network layer now works as a proof of concept	2006-04-28 14:13:50 +00:00
Michael Brown	1488cd3b73	Fix a couple of broken assertions, and align the buffer correctly.	2006-04-28 14:09:31 +00:00
Michael Brown	79f64eea55	Transmit the buffer contents, not the buffer descriptor...	2006-04-28 14:08:41 +00:00
Michael Brown	51feeab445	Add an explicit failure debug message	2006-04-28 14:07:41 +00:00
Michael Brown	084f6b18f7	Exclude bin directory from tags generation. Create something that might be usable as a symbol list for bochs' internal debugger.	2006-04-28 14:07:08 +00:00
Michael Brown	d8e99bf28f	Gave up on adding POSIX errno's as required, and just added (almost) all of them in one go. EBADIMG has been replaced by ENOEXEC, and EIMGRET by ECANCELED.	2006-04-28 13:44:34 +00:00
Michael Brown	cfae86f6c8	Glenn managed to shrink .text by 5 more bytes.	2006-04-25 21:48:16 +00:00
Michael Brown	fee8b91015	D'oh	2006-04-25 12:56:18 +00:00
Michael Brown	7a82c3eca3	Added missing ssize_t	2006-04-25 12:55:23 +00:00
Michael Brown	cf3783b4ca	Actually, it's probably a good idea to have packet buffers avoid 4kB crossings.	2006-04-25 12:11:36 +00:00
Michael Brown	00a1de964d	Update to use POSIX-like API.	2006-04-25 12:04:07 +00:00
Michael Brown	face774c4c	Fixed erroneous comparison	2006-04-25 11:54:58 +00:00
Michael Brown	95f8a42930	Removed incorrect comment; malloc() is inefficient only when the alignment and size are both powers of two, and there's no way to specify an alignment through the malloc() interface anyway.	2006-04-25 10:41:49 +00:00
Michael Brown	4e92f29c9e	Now passes trivial tests. free_memblock() needs neatening up.	2006-04-25 04:01:58 +00:00
Michael Brown	b601a7d355	Updated memory allocator to improve support for unaligned or partially aligned blocks. Moved header to include/malloc.h, since we now also provide the POSIX-like malloc()/free() pair. Not yet tested.	2006-04-25 03:30:46 +00:00
Michael Brown	2f0d412210	Add __constant_flsl(), because it's useful for finding out the next power-of-two up from a given constant via ( 1 << fls ( constant - 1 ) ) fls(), flsl(), ffs() and ffsl() appear in strings.h according to POSIX.	2006-04-24 23:00:32 +00:00
Michael Brown	a81f96998b	Added missing headers required for compilation in Etherboot.	2006-04-24 19:35:10 +00:00
Michael Brown	455b76980f	Added pkb_reserve().	2006-04-24 19:34:51 +00:00
Michael Brown	26749951dc	We have our own ARP layer now.	2006-04-24 19:19:13 +00:00
Michael Brown	fcf765e42d	Add missing {register,free}_netdev(). Tie into existing driver API; we'll fix that up soon.	2006-04-24 18:44:50 +00:00
Michael Brown	832e86246b	gcc is rather over-aggressive about optimising out static data structures even when __atribute__ (( unused )) is correctly set...	2006-04-24 18:31:37 +00:00
Michael Brown	4c4e4de18f	(librm_base-1b) is already an offset; no need to apply OFFSET(). Doing so, in fact, seems to expose an assembler bug; (a-b-0) is apparently not the same as (a-b). Go figure.	2006-04-24 18:29:47 +00:00
Michael Brown	824d6ffa7f	Header rearrangement. I want to get to the point where any header in include/ reflects a standard user-level header (e.g. a POSIX header), while everything that's specific to gPXE lives in include/gpxe/. Headers that reflect a Linux header (e.g. if_ether.h) should also be in include/gpxe/, with the same name as the Linux header and, preferably, the same names used for the definitions.	2006-04-24 15:42:49 +00:00
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.	2006-04-24 15:38:53 +00:00
Michael Brown	fdc2ee79db	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.	2006-04-24 15:33:06 +00:00
Michael Brown	0d97f0d482	Obviate uip_init(); our bss is zeroed at startup already.	2006-04-24 15:31:02 +00:00
Michael Brown	5423f876fb	Don't bother poisoning lists; it costs code size.	2006-04-24 15:28:56 +00:00
Michael Brown	1d7cfd5acf	Prototype now clashes with the macro in arch/i386.	2006-04-24 15:27:58 +00:00
Michael Brown	510ccb2900	Added __constant_memcpy() based on version in Linux's string.h. Added memswap().	2006-04-24 15:25:25 +00:00
Michael Brown	b6b6a0b5fe	First draft of a dynamic memory allocator	2006-04-24 15:21:18 +00:00
Michael Brown	e323d1a29b	Add "net" directory. Avoid including debug information in bin/%.s output, since the whole point is to have easy-to-read assembler.	2006-04-24 15:20:01 +00:00
Michael Brown	6209bd873a	First sketch of a new net device API.	2006-04-19 12:07:46 +00:00
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.	2006-04-19 11:32:24 +00:00
Michael Brown	b89ccac02d	Updated to remove obsolete constants	2006-04-19 02:11:56 +00:00
Michael Brown	3ca7dbe7ca	Added the concept of a network interface (a network-layer concept) as separate from a network device (a link-layer concept).	2006-04-19 02:09:08 +00:00
Michael Brown	d65a66606b	Typo	2006-04-19 02:08:27 +00:00
Michael Brown	2558439ce4	First version, based on include/linux/list.h, stripped down to just those functions we are likely to need. Still need to come up with a way of getting the linker to create static lists using this linking mechanism.	2006-04-19 02:05:50 +00:00
Michael Brown	d24042f0bb	Update now that if_ether.h has moved.	2006-04-19 01:56:10 +00:00
Michael Brown	4f3581e99c	Added ENOENT and EAFNOSUPPORT	2006-04-19 01:54:53 +00:00
Michael Brown	ab139ceda9	Added pkb_unput() and pkb_len().	2006-04-19 01:54:24 +00:00
Michael Brown	744b895077	Make flags more efficient. Add 'raw' net_addr facility (needed for ARP).	2006-04-19 01:53:49 +00:00
Michael Brown	49f933fbc3	Moved if_ether.h and if_arp.h to include/gpxe, for consistency with Linux kernel. Removed obsolete struct arprequest from if_arp.h and put it in nic.c so that nic.c will still compile. ARP will very shortly be handled by net/arp.c instead.	2006-04-19 01:52:41 +00:00
Michael Brown	9f67ad9db0	First version. ARP protocol independence in less than the size of uIP's Ethernet-and-IPv4-only ARP module. :)	2006-04-19 01:43:56 +00:00
Michael Brown	363905e1b6	Add missing prototype	2006-04-19 01:42:33 +00:00
Michael Brown	02d342f38f	First version	2006-04-19 01:42:03 +00:00
Michael Brown	0b561ce972	First sketch	2006-04-18 17:52:51 +00:00
Michael Brown	42b659f926	First version	2006-04-18 17:49:51 +00:00
Michael Brown	0864a73347	First version, based on the concepts in linux/skbuff.h	2006-04-18 17:47:01 +00:00
Michael Brown	1a60444fe4	Added netmask and gateway global options. Added iSCSI testing.	2006-04-05 11:46:18 +00:00
Michael Brown	6446767258	First draft of iSCSI protocol support. Is capable of retrieving disk blocks.	2006-04-05 11:44:56 +00:00
Michael Brown	9ea782d339	Make pcap_inject non-static, so that its prototype doesn't conflict with the real pcap_inject in the case where we do have it.	2006-04-05 11:44:05 +00:00
Michael Brown	c8a7133e9f	Added tcp_buffer, to give applications a zero-cost place to build data to be transmitted.	2006-04-05 11:43:01 +00:00
Michael Brown	988bb50979	Added set_netmask() and set_gateway()	2006-04-05 11:41:15 +00:00
Michael Brown	ee058362fa	We don't need to know anything about ARP	2006-03-24 17:39:05 +00:00
Michael Brown	90892d5ec7	Allow specifying the local IP address via --from.	2006-03-24 17:28:40 +00:00
Michael Brown	b44332eb7d	Split non-TCP portions of the stack out into ip.[ch]. Added set_ipaddr().	2006-03-24 17:22:09 +00:00
Michael Brown	1c607470e3	Put in a substitute pcap_inject() function, since earlier versions of libpcap are lacking the function. For now, we always use the substitute version, since there's no easy way to determine whether or not we need it.	2006-03-24 16:43:12 +00:00
Michael Brown	7e61f38799	Moved "hello world" protocol implementation out of prototester.c and into the first standalong uIP-based protocol module.	2006-03-23 22:37:05 +00:00
Michael Brown	508dcdb303	Added container_of(). This seems about the best place to put it, since the definition of it uses offsetof(), and the two concepts are related.	2006-03-23 22:07:21 +00:00
Michael Brown	99032becce	Pick up the gPXE include files when building prototester.	2006-03-23 21:35:20 +00:00
Michael Brown	2299435f1c	Added prototype for inet_ntoa, even though we don't have the function yet, in order to allow prototester.c to compile. It might be worth changing all the uses of "%@" in printf to use "%s" and inet_ntoa instead, in order to improve the portability of our code.	2006-03-23 21:34:25 +00:00
Michael Brown	a4a0244aa3	Moved uIP wrapper out of prototester.c and into proto/tcp.c.	2006-03-23 21:32:03 +00:00
Michael Brown	17c0253ca0	Add include/gpxe as a directory to scan. Exclude proto/uip, since uip.c and uip_arp.c both have global variables called "c", which screws up doxygen's auto-generation of links to file documentation when it encounters a file name such as "hello.c".	2006-03-23 21:06:36 +00:00
Michael Brown	2bc7c746a6	Updated with "doxygen -u" from doxygen 1.4.4	2006-03-23 20:39:26 +00:00
Michael Brown	05b284399e	Moved old tcp.h to old_tcp.h, to avoid name clash with new (uIP-based) tcp.h.	2006-03-23 20:34:08 +00:00
Michael Brown	af23ff8a24	Assertions are now handled via the POSIX-like <assert.h>.	2006-03-23 19:33:57 +00:00
Michael Brown	55497b3402	Added missing #endif	2006-03-23 19:23:25 +00:00
Michael Brown	cb8e89de15	Added assert.h, with assert() defined (almost) as per POSIX, and linker_assert() defined as gPXE-specific.	2006-03-23 17:28:51 +00:00
Michael Brown	531371efa2	Removed to make way for the uIP-based tcp.c.	2006-03-23 16:59:25 +00:00
Michael Brown	dde1c5ad18	Moved include/in.h to include/gpxe/in.h, so that it can be included by prototester.	2006-03-23 16:45:01 +00:00
Michael Brown	eaf40883ff	Add Makefile for hijack and prototester utilities.	2006-03-23 13:11:41 +00:00
Michael Brown	21c58729ae	Add debug symbols to objects. (They will be stripped out of the final -Obinary build anyway, so it doesn't waste any space).	2006-03-23 13:09:29 +00:00
Michael Brown	b2c94b32fc	Make the application state a void *.	2006-03-23 13:08:06 +00:00
Michael Brown	218c26ff2b	Can now also print data sent by the remote side.	2006-03-23 13:06:08 +00:00
Michael Brown	0d506a5c6a	Now capable of sending "Hello world!" via TCP.	2006-03-23 12:25:28 +00:00
Michael Brown	911486fe41	Added basic http-specific option parsing	2006-03-22 22:35:32 +00:00
Michael Brown	5263a5abf4	Started adding structure to allow for separate protocol tests, with individual options. Created the embryonic beginnings of a cleanly separated driver and protocol stack API.	2006-03-22 21:25:35 +00:00
Michael Brown	c32e83ad8d	Skeleton version: contains device driver (connecting to network via hijack daemon) and a functional but very ugly and very primitive wrapper around uIP. This passes proof-of-concept testing; it successfully initiates a TCP connection and responds to pings.	2006-03-22 02:23:20 +00:00
Michael Brown	bb37bd47f8	Added from uip-0.9/uip/uip_arp.[ch]	2006-03-22 02:14:55 +00:00
Michael Brown	417e896f0a	Remove htons(); it is provided elsewhere in Etherboot	2006-03-22 01:25:43 +00:00
Michael Brown	1c7c24f21f	Basic, functional-but-extremely-pessimal versions (taken from uip-0.9/unix/uip_arch.c).	2006-03-22 01:24:13 +00:00
Michael Brown	c5a9c38606	Terminate cleanly on SIGINT or SIGHUP	2006-03-21 17:48:33 +00:00
