Michael Brown 335b99a39d Move [v]ssnprintf() from iscsi.c into vsprintf.c; we need them 
elsewhere as well.
 2007-05-31 13:26:50 +00:00
Michael Brown 735e07268e Update HTTP to use data-xfer interface. 2007-05-29 15:37:09 +00:00
Michael Brown 0dfd5b84fd Updated FTP to use data-xfer API. 2007-05-28 20:11:02 +00:00

Michael Brown 63719deea9 Introduce name resolution interface and named socket opener. 2007-05-27 01:07:00 +00:00
Michael Brown a1210e4fca Eliminate PF_INET; just use the AF_INET from the struct sockaddr instead. 2007-05-26 20:41:23 +00:00
Michael Brown 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.

Add some debugging statements.
 2007-05-26 15:04:36 +00:00
Michael Brown 3601103381 Modify process semantics; rescheduling is now automatic. 
Add reference-counting to processes.

Michael Brown 3e2c6b6736 pkbuff->iobuf changeover 
Achieved via Perl using:

perl -pi -e 's/pk_buff/io_buffer/g; s/Packet buffer/I\/O buffer/ig; ' \
	-e 's/pkbuff\.h/iobuf.h/g; s/pkb_/iob_/g; s/_pkb/_iob/g; ' \
	-e 's/pkb/iobuf/g; s/PKB/IOB/g;'
 2007-05-19 18:39:40 +00:00
Michael Brown 68dd826b86 Add alloc_iob() and free_iob(). (Direct search-and-replace 
equivalents for alloc_pkb() and free_pkb(), which will be retired in
due course).
 2007-05-18 14:45:16 +00:00
Michael Brown 86a948ccbe Added POSIX-style blocking I/O calls, for use by PXE TFTP API. 2007-05-18 14:19:22 +00:00
Michael Brown 6b6fc1d5ea Allow construction of PXE status code from internal error number. 2007-05-18 14:17:35 +00:00
Michael Brown 59e738d756 Prefix all the open()-family routines with xfer_, to disambiguate them 
from the normal POSIX-style open()
 2007-05-18 14:16:06 +00:00
Michael Brown 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
Michael Brown 5471bfbbbe Data-transfer interface should now be functionally complete. 2007-05-15 15:23:09 +00:00

functions.
 2007-05-01 10:17:29 +00:00

output buffering defintions and the like)
 2007-04-09 18:01:43 +00:00
Michael Brown 520d9c36af Updated ISAPnP, EISA, MCA and ISA buses to current device model. 
ISA 3c509 is currently non-functional, although the EISA (3c509-eisa) and
MCA (3c529) variants should build OK.

None of this code is yet tested.
 2007-03-10 18:08:33 +00:00

up in the same colour as debug messages for the application stream.
 2007-01-31 03:43:40 +00:00

Michael Brown 395c76e94d Use "dbg_stream" rather than "stream" as a variable name in 
DBG_AC_IF(), to avoid namespace collisions.
 2007-01-30 10:12:19 +00:00
Michael Brown 1a79437888 Added async_block_progress() and default SIGUPDATE handler. 2007-01-29 04:15:24 +00:00
Michael Brown c42a384709 Moved most buffer debug messages to DBG2. 
Make expand_buffer() a non-inline function, so that we can add debug
messages.

Expandable buffers now don't *always* round up to the next power of two.
This allows e.g. loading a 137MB ISO image on a machine with only 256MB
RAM...
 2007-01-29 04:12:29 +00:00
Michael Brown afe4e011ac Move tolower() etc to ctype.h as per ISO C 2007-01-26 03:25:19 +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

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 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

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 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".

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 9debfed07a Place command-line inline, to save on memory allocation hassles. 2007-01-12 05:26:19 +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 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.
 2007-01-04 04:20:08 +00:00
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!
 2006-12-22 12:24:12 +00:00
Michael Brown 73e3e02367 Fix prototype of random() and move to stdlib.h 2006-12-22 01:44:51 +00:00
Michael Brown 66a7ed23cb Make start_timer() and stop_timer() robust against incorrect usage. 2006-12-22 01:35:21 +00:00
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
