Michael Brown da9dc834b1 Help quick testing of building Linux code inside gPXE 2007-01-24 23:38:05 +00:00
Michael Brown 9cf5c4557d Add Linux-compatible rol32/ror32 functions. Amazingly, gcc will
optimise these down to the correct single "roll"/"rorl" instruction.
2007-01-24 23:31:58 +00:00
Michael Brown 18f9f939a8 Introduce structured error codes. 2007-01-19 13:15:26 +00:00
Michael Brown c2352dc8de Add POSIX prototypes for time functions, to allow external code to build
more easily within gPXE.

Note that we don't have function bodies for these functions yet.
2007-01-19 03:09:22 +00:00
Michael Brown 4256b3338a Split random number generation out into core/random.c, and create the
correct prototypes for srandom(), rand() and srand().
2007-01-19 02:02:59 +00:00
Michael Brown f4c1e564a1 vsprintf.h is gPXE-specific; move it to include/gpxe 2007-01-19 01:17:23 +00:00
Michael Brown 73b09ecba6 Use stdio.h instead of vsprintf.h 2007-01-19 01:13:12 +00:00
Michael Brown 06475f7b69 Finally move the prototypes for printf() and friends to stdio.h 2007-01-19 00:58:49 +00:00
Michael Brown 1a0ca661c2 4.3BSD says that bcopy and bzero are defined in strings.h, not string.h 2007-01-19 00:51:13 +00:00
Michael Brown b02a564297 Add missing prerequisite include 2007-01-19 00:39:12 +00:00
Michael Brown 4e3976711d A working name resolution framework 2007-01-18 22:38:13 +00:00
Michael Brown 075f8144ff Have DHCP set the nameserver, rather than DNS read the DHCP nameserver
value.
2007-01-18 21:22:03 +00:00
Michael Brown c014f607a8 Use total free memory as advertised window. This seems to be sufficient
to avoid drops even on slow NICs.
2007-01-18 20:39:17 +00:00
Michael Brown 6d4e37cf42 Move include/malloc.h to include/gpxe/malloc.h, since everything in there
is now gPXE-specific.  (The standard malloc() et al have been in stdlib.h
for a while).

Add free memory counter.
2007-01-18 20:11:04 +00:00
Michael Brown d12770e254 console.h is no longer needed for debugging 2007-01-18 19:13:25 +00:00
Michael Brown f781a98ac4 Add DBGLVL_PROFILE 2007-01-18 17:59:59 +00:00
Michael Brown 5b00fbade3 Increase window size to 64kB. Line rate downloads on a 100Mbps link,
anyone?
2007-01-18 16:39:55 +00:00
Michael Brown c8b3e969a0 Allow buffers to be pre-expanded on demand. 2007-01-18 15:13:41 +00:00
Michael Brown 35776f481c Don't always zero memory in malloc(). This saves around 2us on a
full-length PKB allocation.
2007-01-18 12:54:18 +00:00
Michael Brown dd6d94004f HTTP/DNS now working fully asynchronously. HTTP/IP addresses and any
other protocol won't work at the moment.
2007-01-18 03:39:45 +00:00
Michael Brown 0b11733b75 Replacement for fetch() which operates asynchronously and identifies
protocols by URI scheme.
2007-01-18 03:37:05 +00:00
Michael Brown 99e58865c7 Use struct sockaddr rather than struct sockaddr_tcpip
Tidy up code
2007-01-18 03:35:00 +00:00
Michael Brown 6601a7da6a Added async_uninit() to simplify failure paths. 2007-01-18 03:29:40 +00:00
Michael Brown 5a807994d8 Add utility function to parse port from URI 2007-01-18 03:28:55 +00:00
Michael Brown 8ffbbebf11 Ensure that struct sockaddr is long enough... 2007-01-18 03:28:29 +00:00
Michael Brown 9828181e3b Obsolete 2007-01-18 01:05:09 +00:00
Michael Brown 544fa25928 Rename e{malloc,realloc,free} to u{malloc,realloc,free}, to more obviously
reflect the fact that they allocate and deallocate user memory (i.e.
things reached through a userptr_t).
2007-01-16 08:36:42 +00:00
Michael Brown ff8528ea9a Create and use async_block() macro; it cuts down on the visual overhead
of blocking on asynchronous operations, when that isn't an important
aspect of the code.
2007-01-16 08:10:54 +00:00
Michael Brown 9af12d5fba A working DNS resolver (not yet tied in to anything) 2007-01-15 17:31:35 +00:00
Michael Brown df0397f334 Update TFTP and FTP to take the same temporary URI scheme as HTTP 2007-01-15 09:58:26 +00:00
Michael Brown c676591cd1 Unmaintained example code is probably worse than useless. 2007-01-15 09:06:12 +00:00
Michael Brown 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
Michael Brown 26166cf5e0 Added a URI parser that should be standards conformant. (It can certainly
handle something as convoluted as

Michael Brown 99272f958b Typo 2007-01-14 15:13:33 +00:00
Michael Brown 10c9b03cdb Actually, the initrd image should be architecture-independent. 2007-01-14 15:07:11 +00:00
Michael Brown 784e10635a Can almost start a kernel now. It dies with "No setup signature found" 2007-01-14 06:36:20 +00:00
Michael Brown 797edf28b7 Replace image->entry with image->priv. 2007-01-14 04:04:28 +00:00
Michael Brown dca369ddc3 Call hide_etherboot() from startup(), rather than requiring the prefix to
do it.
2007-01-14 00:53:56 +00:00
Michael Brown c2708df14a Make shutdown functions callable by OS image's exec methods. 2007-01-14 00:16:41 +00:00
Michael Brown aaed3d50a8 Some operating systems get a nasty shock if a region of the E820 map seems
to start on a non-page boundary.  Make life safer by rounding out our
edited regions.
2007-01-13 23:38:33 +00:00
Michael Brown 526d314266 Advertise a larger MSS to improve TCP performance. 2007-01-13 17:36:17 +00:00
Michael Brown 3b77c7aa1b Hex dumps are now integrated into the DBG() framework. 2007-01-13 16:49:38 +00:00
Michael Brown 497c3a5aad Fixed HTTP 2007-01-12 19:18:13 +00:00
Michael Brown 369754f959 Whitespace fix 2007-01-12 19:17:25 +00:00
Michael Brown 83b7933f8a Damn it; my lovely resilient scheme falls down when you have a protocol
that switches from line-oriented to byte-oriented partway through, such as
HTTP.
2007-01-12 18:09:14 +00:00
Michael Brown ad22cccc09 No need to maintain a received byte count; we always fill in sequential
order so we can just use buffer->fill.
2007-01-12 17:16:46 +00:00
Michael Brown 996b091b50 Added generic line-buffering code (a la stdio) 2007-01-12 17:08:37 +00:00
Michael Brown b45a9bfa2d Added missing declaration. 2007-01-12 10:07:56 +00:00
Michael Brown e2c0055e23 Let ifmgmt.c take care of calling efree(), since it's the once which
took out the contract to eventually call efree() when it called fetch().

Maintain the most recently loaded image at the start of the list, so that
imgautoselect() will pick it.
2007-01-12 09:46:10 +00:00
Michael Brown 39ede8c7e8 Added dhcp() user-level command. 2007-01-12 09:20:11 +00:00
Michael Brown 2be2f3b205 Rearrange struct image to reflect usage of the fields 2007-01-12 08:58:16 +00:00
Michael Brown 48e0fc3447 API change: the raw image will no longer be (hypothetically) discarded
after a call to load().
2007-01-12 08:15:25 +00:00
Michael Brown 6fdc6c81a6 Force probing of multiboot before ELF. 2007-01-12 08:10:35 +00:00
Michael Brown 475d6d1f7c fetch() now knows nothing about struct image; it simply loads a file and
returns the allocated buffer.
2007-01-12 08:02:27 +00:00
Michael Brown 2876197306 Allow "imgexec" with no arguments to boot the file that was loaded with
"kernel".
2007-01-12 07:32:46 +00:00
Michael Brown f135a37f30 Cleaner separation between imgXXX() functions and image_cmd.c 2007-01-12 07:22:20 +00:00
Michael Brown 742f242863 Add free_image 2007-01-12 06:26:59 +00:00
Michael Brown 9817f93094 Add basic "fetch" and "imgstat" commands. 2007-01-12 06:05:27 +00:00
Michael Brown b9fea9cbac Added IMAGE_LOADED flag and find_image() 2007-01-12 06:03:02 +00:00
Michael Brown e96041872e Added missing declaration. 2007-01-12 05:27:02 +00:00

Michael Brown f15482d85f Added basename() to make automatically naming images easier. 2007-01-12 05:24:51 +00:00
Michael Brown 29dadc5ec6 Build automatically expanding buffers from struct buffer and erealloc(). 2007-01-12 03:51:04 +00:00
Michael Brown 45ec9c907e First version of an external memory allocator (not tested) 2007-01-12 03:15:29 +00:00
Michael Brown 859da6bd32 Allow external code to update hidden memory regions. 2007-01-12 03:13:04 +00:00
Michael Brown 2c66588f3e Add UNULL 2007-01-12 01:40:12 +00:00
Michael Brown f59ad50504 Provide registration mechanism for loaded images, so that we can e.g.
refer to them by name from the command line, or build them into a
multiboot module list.

Use setting image->type to disambiguate between "not my image" and "bad
image"; this avoids relying on specific values of the error code.
2007-01-11 23:43:29 +00:00
Michael Brown 79a399c05a alloca() can be useful in some (limited) circumstances. 2007-01-11 23:19:31 +00:00
Michael Brown c468c68661 Add command line that can be passed to executed images. 2007-01-11 21:19:29 +00:00
Michael Brown 819cd3f41c Limit -ENOEXEC to mean "this is not in my format". 2007-01-11 17:06:25 +00:00
Michael Brown 6a03552381 Distinguish between ENOMEM (as representing a lack of internal memory
as allocated by malloc()) versus all other errors, in particular
ENOBUFS (representing a lack of external buffer space, e.g. in a
device's TX queue or a user buffer).
2007-01-11 16:30:21 +00:00
Michael Brown c810baad37 Use generic "struct image" rather than "struct elf". 2007-01-11 16:10:32 +00:00
Michael Brown c6c63d954d Rename "image" field to "data", because "image->image" is just confusing. 2007-01-11 16:07:30 +00:00
Michael Brown 4fc9333159 Move include/image.h to include/gpxe/image.h 2007-01-11 16:04:36 +00:00
Michael Brown 230f16538f Create include/gpxe/elf.h for the ELF bits that aren't part of the ELF
standard and so don't belong in include/elf.h
2007-01-11 15:25:07 +00:00
Michael Brown 0010e10ef3 Update TFTP to use a struct buffer rather than a callback.
Add debug autocolourisation to TFTP.
2007-01-11 15:14:54 +00:00
Michael Brown 7ad1c2eaa8 Removed the Etherboot-specific ELF-image code and replaced it with a
generic ELF loader, to be used by the multiboot code.
2007-01-11 14:44:03 +00:00
Michael Brown 3634e705b7 Remove osloader.c and replace with a prep_segment() that uses userptr_t
and get_memmap() in image/segment.c
2007-01-11 14:32:26 +00:00
Michael Brown c980cdd0aa Move memmap.h out of arch/i386; it no longer contains anything
architecture-dependent and is needed by the ELF code.
2007-01-11 14:08:44 +00:00
Michael Brown fbfed96965 buffer.c should be using copy_{to,from}_user, rather than
copy_{to,from}_phys.
2007-01-11 05:42:06 +00:00
Michael Brown a3ed0cbbc7 Extract packet-padding login from rtl8139.c to a separate pkbpad.c file. 2007-01-11 05:25:50 +00:00
Michael Brown 6918cf9e9e Change FTP to use a data buffer rather than a callback function. 2007-01-11 04:51:20 +00:00
Michael Brown e2dcd05b67 Update buffer-handling code to enable expandable buffers. 2007-01-11 03:50:47 +00:00
Michael Brown bb2024c6d6 Move include/buffer.h to include/gpxe/buffer.h 2007-01-11 01:47:26 +00:00
Michael Brown d9ba8f790b Add route() function to display routing table. 2007-01-10 20:38:20 +00:00
Michael Brown 1fa5cd0e2b Add find_pci_netdev() 2007-01-10 16:16:05 +00:00
Michael Brown fdc97499bf Add device description fields to struct device. 2007-01-10 15:27:48 +00:00
Michael Brown dad5274522 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
Michael Brown c821a7b20d Add udp_sendto_via() to allow e.g. DHCP to transmit without first having
to set up dummy routing entries.
2007-01-10 02:31:38 +00:00
Michael Brown f008b77ba2 Allow an explicit network device to be specified for IP-layer
transmissions.
2007-01-10 02:25:11 +00:00
Michael Brown 55e590ab3a Move header file for usr/autoboot.c to include/usr 2007-01-10 02:03:20 +00:00
Michael Brown d24b80acf2 Added network interface management commands 2007-01-10 01:55:07 +00:00
Michael Brown 98b6154c3e Add "name" field to network device, to facilitate netdev commands. 2007-01-09 23:48:18 +00:00
Michael Brown 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
Michael Brown 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
Michael Brown b7fcfe8ece Added net device TX queue; this will be needed to support the PXE UNDI API
(which will need us to wait for TX completions).

Added debug autocolourisation to netdevice.c
2007-01-09 20:18:31 +00:00
Michael Brown 76525294ee Clean up connection closing and permanent failure logic. 2007-01-09 04:31:33 +00:00
Michael Brown 79c5f0ba04 Added PCI_BASE_CLASS() macro 2007-01-08 03:32:41 +00:00

Michael Brown 20c9fc407e Remove types and prototypes now provided in the undi*.h headers. 2007-01-08 03:05:34 +00:00
Michael Brown 9780fef360 Partial implementation of UNDI loader caller. 2007-01-05 03:24:39 +00:00
Michael Brown 0638945c7e 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
Michael Brown 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
Michael Brown 350603cb86 Don't include __FUNCTION__ in assert() messages; it was causing the
function name to appear within the objects even in non-asserting
builds.  (This could be considered a gcc bug.)

Removing __FUNCTION__ from assert() reduces the size of bin/blib.a by
around 2.5%!
2007-01-04 13:48:13 +00:00
Michael Brown 0c03bb5a9a Make open() and close() an official part of the netdevice API.
Call netdevice's poll() and transmit() methods only when device is open.

Michael Brown 7fafa89258 A DHCP session holds a persistent reference to a network device 2007-01-04 03:42:28 +00:00
Michael Brown ac53da1790 Added missing #include 2007-01-04 03:40:07 +00:00
Michael Brown b29861a5aa IPv6 minirouting table entries hold persistent references to net devices. 2007-01-04 03:28:30 +00:00
Michael Brown b22d4405c0 An AoE session holds a persistent reference to a net device. 2007-01-04 03:21:45 +00:00
Michael Brown bdf79ec8dc Use hotplug support to notify persistent reference holders when a
net_device is unregistered.
2007-01-04 03:09:28 +00:00
Michael Brown 0063725d28 Minimal hotplug support: provide a facility for notifying persistent
reference holders that their reference is about to become invalid.
2007-01-04 03:08:16 +00:00
Michael Brown a0525a4ed3 Verify checksums on the RX datapath.
Simplify checksum generation on the TX datapath.
2007-01-03 20:48:52 +00:00
Michael Brown b91b9d3d88 Use whole bytes for the ACKED and RCVD portions of tcp_state; it
produces slightly smaller code.
2006-12-30 01:32:22 +00:00
Michael Brown 2494625702 Added auto-colourising DBGC() macro 2006-12-29 03:05:21 +00:00
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.
2006-12-29 00:44:31 +00:00
Michael Brown 61ed298bc7 Merge changes from mcb-tcp-fixes branch. 2006-12-27 23:09:46 +00:00
Michael Brown a2e3357825 Cannot immediately overwrite the peer address when we parse
TargetAddress from the login response, because we still need the old
address while we close the connection!

Michael Brown 9485478acc ibft_fill_data() prototype change. 2006-12-21 18:42:51 +00:00
Michael Brown ab242a760d Add ability to shut down iSCSI connection 2006-12-21 17:17:47 +00:00
Michael Brown cacd6b1d04 KEY_XXX constants are now defined in gpxe/keys.h. Kept separate from
curses.h so that you don't have to suffer the curses namespace pollution
just to get the symbolic key names.
2006-12-20 22:24:45 +00:00
Michael Brown 46c3eeba2a Fix definition of KEY_END 2006-12-20 22:17:44 +00:00
Michael Brown 2ae27f44d9 Add insert/delete and document keys, and documentation. 2006-12-20 22:11:28 +00:00
Michael Brown 791c7d3bf4 Added code to interpret ANSI keypress sequences into KEY_XXX constants. 2006-12-20 21:56:50 +00:00
Michael Brown 96a1a2c6f0 Key definitions 2006-12-20 21:53:07 +00:00
Michael Brown b9f8599537 Define KEY_MIN and use it in kb.c. 2006-12-20 21:10:32 +00:00
Michael Brown cbeec25662 settings_ui() now returns a status code. 2006-12-20 11:42:48 +00:00
Michael Brown 84202d89f0 Split the (quick hack) boot logic out from main.c to autoboot.c, add a
"boot" command to attempt booting from within the command shell, fall back
to shell if boot fails for any reason.
2006-12-20 07:04:08 +00:00
Michael Brown f8910410fe Add attr_{get,set,on,off} as static inlines. 2006-12-20 06:06:38 +00:00
Michael Brown 8f9336e0c1 Add "config" command to access config UI 2006-12-20 05:37:33 +00:00
Michael Brown b93ff48173 Added descriptive text for settings and setting types, and display it in

Michael Brown 35edecac34 Move {show,set,clear}_setting() to {show,set,clear}_named_setting().

set_setting() handles calling clear_setting() when appropriate, so that
individual setting types don't have to check for empty strings.
