Everything except the SCSI interface should now be present
2007-07-08 18:51:56 +01:00
9b28b25332

b34d4d0449
Separate the "is data ready" function of xfer_seek() into an

Kill off unused request() method in data-xfer interface.
2007-07-08 02:10:54 +01:00
4c418d2100
Use net_device_operations structure and netdev_nullify() to allow for
...
safe dropping of the netdev ref by the driver while other refs still
exist.
Add netdev_irq() method. Net device open()/close() methods should no
longer enable or disable IRQs.
Remove rx_quota; it wasn't used anywhere and added too much complexity
to implementing correct interrupt-masking behaviour in pxe_undi.c.
2007-07-07 16:43:39 +01:00
934b70d62c
Apply global DHCP options when register_dhcp_options() is called. Do
...
not apply DHCP options in dhcp_configure_netdev().
2007-07-06 17:07:50 +01:00
b3ca73c303
Remap EBADF to PXENV_STATUS_TFTP_FILE_NOT_FOUND; the only user is
...
posix_io.c and this PXE error makes more sense in this context.
2007-07-05 18:47:46 +01:00

5f17089b14
pxe_netdev now holds a reference to the network device.
...
Use generic fields in struct device_description rather than assuming
that the struct device * is contained within a pci_device or
isapnp_device; this assumption is broken when using the undionly
driver.
Add PXENV_UNDI_SET_STATION_ADDRESS.

10d0a1f8c7
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.

2007-05-19 18:39:40 +00:00
68dd826b86
Add alloc_iob() and free_iob(). (Direct search-and-replace

...
from the normal POSIX-style open()
2007-05-18 14:16:06 +00:00
b1755462ab
Do not hold self-references. This then avoids the problem of having to
...
ensure that we only drop our self-reference exactly once.
To maintain the guarantee that an object won't go out of scope
unexpectedly while one of its event handlers is being called, the
event-calling functions now automatically obtain and drop extra
references.
2007-05-15 16:53:46 +00:00

6d4e37cf42
Move include/malloc.h to include/gpxe/malloc.h, since everything in there

Add free memory counter.

Update TFTP and FTP to take the same temporary URI scheme as HTTP

c676591cd1
Unmaintained example code is probably worse than useless.
2007-01-15 09:06:12 +00:00
4e20d73bb5
Gave asynchronous operations approximate POSIX signal semantics. This
...
will enable us to cascade async operations, which is necessary in order to
properly support DNS. (For example, an HTTP request may have to redirect
to a new location and will have to perform a new DNS lookup, so we can't
just rely on doing the name lookup at the time of parsing the initial
URL).
Anything other than HTTP is probably broken right now; I'll fix the others
up asap.
2007-01-15 08:49:10 +00:00
26166cf5e0

Provide registration mechanism for loaded images, so that we can e.g.

Distinguish between ENOMEM (as representing a lack of internal memory

Add "name" field to struct device to allow human-readable hardware device
...
names.
Add "dev" pointer in struct net_device to tie network interfaces back to a
hardware device.
Force natural alignment of data types in __table() macros. This seems to
prevent gcc from taking the unilateral decision to occasionally increase
their alignment (which screws up the table packing).
2007-01-10 04:22:09 +00:00
c821a7b20d
Add udp_sendto_via() to allow e.g. DHCP to transmit without first having

2007-01-09 23:48:18 +00:00
c65fae2475
Add RX quotas to the net device poll() method. This avoids the problem
...
of alloc_pkb() exhaustion when e.g. an iSCSI-booted DOS session is left
idle for a long time at the C:\ prompt and builds up a huge packet
backlog.
2007-01-09 21:47:01 +00:00
18e5353bed
Rename pkb_available() to pkb_tailroom() for consistency with Linux's

skb_tailroom(). Add pkb_headroom().
2007-01-09 20:56:31 +00:00

Partial implementation of UNDI loader caller.

Add PXE driver-scanning code, capable of locating all PXE ROMs in a system
...
and matching them up to (e.g. PCI) devices.
2007-01-05 01:52:06 +00:00
7e07dfb2f4
Added PXE bus driver (with support only for using PXE structures found

lying about in memory, not for loading from ROM), and UNDI net driver.
2007-01-04 19:38:34 +00:00
350603cb86
Don't include __FUNCTION__ in assert() messages; it was causing the

ce9819af27
Redefine TCP state to include "flags that have been sent" rather than

collapsed.

35edecac34
Move {show,set,clear}_setting() to {show,set,clear}_named_setting().
...
Introduce new {show,set,clear}_setting() that take a struct setting *
rather than a const char *.
set_setting() handles calling clear_setting() when appropriate, so that
individual setting types don't have to check for empty strings.
2006-12-20 04:20:13 +00:00

Use int rather than short for bool; it will give more efficient code.
2006-12-18 16:48:09 +00:00
2ed2b2efe8
Use iskey() and getchar() to interact with console, rather than object

7de5d32ff5
cmdlinelib.c now calls system() rather than doing its own tokenisation
...
(which was extremely heavy on calls to malloc()).
Moved include/command.h to include/gpxe/command.h, since it's
gPXE-specific.
2006-12-08 01:26:11 +00:00

dc06c895fc
Changed length parameter in SPI methods to be a byte length, rather than

931f94dca3
Generalised the SPI abstraction layer to also be able to handle interfaces

that don't provide the full flexibility of a bit-bashing interface.
Temporarily hacked rtl8139.c to use the new interface.

...
Added CHAP authentication
2006-11-28 00:29:02 +00:00
82342e0b8f
Marked memcmp/strcmp as "pure" functions, to allow gcc to optimise

DBG ( "Bad value received!" );
}
2006-11-27 23:50:24 +00:00
c4677c7e73
Implemented realloc(), and changed the semantics of malloc(0) to allow

for realloc(0) being a valid way to free memory.
2006-11-24 16:51:18 +00:00
fdaddd969a
Added "name" field to digest algorithms
2006-11-21 16:14:50 +00:00

57d539aab0
Made it temporarily possible to call MD5 routines directly from external

code, rather than going through the digest layer.
Removed a spurious line of constants.
2006-11-15 04:22:22 +00:00
fedc186fd7
Split login into security negotation and operational parameter

Remove _PROTOCOL macros for gcc 3.2 compatibility
2006-08-09 04:42:14 +00:00
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
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
41af7457a8
Merge of Fredrik Hultin command_line
2006-08-09 02:30:35 +00:00
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
d1a123b1f4
Added TFTP test code (currently just dumps file to console).
2006-08-09 00:09:29 +00:00

Initial (untested) implementation of TFTP over the new UDP API.
2006-08-08 23:45:52 +00:00

The prototype for strcasecmp() is apparently in strings.h.
2006-08-08 22:52:16 +00:00

Added some TFTP definitions for use with the new UDP API.
2006-08-08 22:01:16 +00:00

Added retransmissions to TCP
2006-08-07 18:52:26 +00:00
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
eb24eece0e
Convert some trivial functions to static inlines.
2006-08-03 23:42:03 +00:00
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
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
e24a6cb525
Moved the basic struct sockaddr out of in.h.
2006-08-02 00:06:30 +00:00
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.

beadd82208
Remove unused functions.
2006-08-01 14:26:02 +00:00
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
3a0e293123
Renamed tcpip_if.[ch] to tcpip.[ch]
2006-08-01 14:18:09 +00:00

Added test code to configure the interface for IPv4 after DHCP.

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
6858b14a34
Add pkb_available()
2006-07-19 18:16:48 +00:00

Added missing prototype

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
b8d619e822
Added macros for generating static DHCP options
2006-07-19 16:16:51 +00:00
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
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
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
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
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
19e8b41562
Add code to modify DHCP option values within a block.

encapsulated option; this will be needed for modifications to the options
block.
2006-06-28 18:59:54 +00:00
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.

2006-06-27 17:24:07 +00:00
e442447f37
- multiple static inline definitions added

updated UDP interface
2006-06-25 05:13:17 +00:00
fdc05e2664
created interface for transport-network interface
2006-06-25 05:12:07 +00:00
3a660f9b25
Update ftp.c and hello.c to use the generic async_operations API.
2006-06-19 15:46:58 +00:00
15397db2b4
Placeholder
2006-06-17 23:34:48 +00:00
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
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
bbd9e28061
Simplify TX datapath.
2006-06-16 00:19:46 +00:00
cce2e47ff4
Added iSCSI boot test code
2006-06-14 17:00:25 +00:00
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
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
51a36f1cfb
Change read_bit() to return 0 or -1UL, rather than 0 or 1.
2006-06-12 19:29:50 +00:00
3ed40686c9
Added bit-bashing i2c interface code
2006-06-11 00:57:00 +00:00
e90b64d625
Added sketch of bit-bashing interface common code
2006-06-08 19:47:09 +00:00
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
d78581297b
Improve tcpdump legibility.
2006-06-01 19:23:52 +00:00
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
50415b3aca
Make DBG_DISCARD correct
2006-06-01 12:11:09 +00:00
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
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
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
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
6541338897
Handle multi-sector reads by splitting them into subcommands.
2006-05-29 08:25:31 +00:00
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
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
6d6252067f
Add ETH_P_AOE
2006-05-28 21:47:52 +00:00
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
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
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
3204a1e941
Removed some obsolete INIT_XXX constants.
2006-05-25 01:09:06 +00:00
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
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
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
9dfb9d84b4
Made the LBA48 example clearer.
2006-05-21 16:02:38 +00:00
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
af4aacb978
Added missing @file block
2006-05-20 13:25:07 +00:00
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
444b885a7d
Add EOVERFLOW==ERANGE
2006-05-19 18:53:12 +00:00
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
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
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
b531bd2bda
All uses iscsi_state were removed some time ago; removing the
...
declaration.
2006-05-18 21:38:16 +00:00
2814681d20
all window primitives implemented
2006-05-18 17:51:19 +00:00
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
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
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
441189c6f8
Kill off the "all devices are boot devices" idea
2006-05-16 14:42:15 +00:00
7cd0390013
Add list_for_each_entry_safe.
2006-05-16 14:14:31 +00:00
ceba6ecb75
Added generic device model.
2006-05-16 14:10:21 +00:00
6b514393d3
Change movetoyx(), putc() and getc() to methods of the screen.
2006-05-15 09:51:18 +00:00
dccc6aed3a
lightweight xcurses implementation for etherboot (Michael made me do it...)
2006-05-15 09:29:48 +00:00
f25731d08f
Split "iSCSI as a SCSI device" out from "iSCSI as a TCP protocol".
2006-05-14 23:29:16 +00:00
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
2421723a15
Rewrote printf and friends to better support standard C semantics.
2006-05-14 02:51:55 +00:00
1ad72e0e79
Add 64-bit byte-swapping operations.
2006-05-13 11:40:39 +00:00
5009f8d6a2
Provide a SCSI device interface to the iSCSI protocol
