Michael Brown f2fa390ae6 Everything except the SCSI interface should now be present 2007-07-08 18:51:56 +01:00
Michael Brown 9b28b25332 iSCSI updated to use data-xfer interface on the socket side (TCP). 
SCSI interface not yet implemented.
 2007-07-08 16:04:13 +01:00
Michael Brown edded7546e Limit xmit window to one MTU. (Path MTU discovery not yet 
implemented; should be done at some point.)
 2007-07-08 14:33:53 +01:00
Michael Brown 3e1dd0772a Fix typo that was preventing any DHCP option applicators from being 
applied.
 2007-07-08 14:32:20 +01:00
Michael Brown 237e23c1c9 Add debug message when nameserver setting is applied/changed via DHCP. 2007-07-08 14:31:51 +01:00
Michael Brown 35afb379af TCP limits advertised TCP window to size of application window 
obtained via xfer_window().
 2007-07-08 14:14:59 +01:00
Michael Brown b34d4d0449 Separate the "is data ready" function of xfer_seek() into an 
xfer_window() function, which can return a scalar rather than a
boolean.

Michael Brown ca4c6f9eee Kill off unused request() method in data-xfer interface. 2007-07-08 02:10:54 +01:00
Michael Brown e5d8ede978 Re-added symtab to CLEANUP list 2007-07-07 17:49:59 +01:00
Michael Brown e505ceb942 Revert "Cope with builds with differing debug options within a second of each" 
This reverts commit fc5f6c9de2.

Reverted commit breaks the much more common case of changing the debug
options in subsequent builds without any code changes.
 2007-07-07 17:49:07 +01:00
Michael Brown 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.

Michael Brown bfc335faa8 Added PXENV_GET_FILE_SIZE. 
Documented non-blocking nature of PXENV_FILE_READ.

Changed FileName field in PXENV_FILE_OPEN to be a SEGOFF16, to avoid a
fixed 256-byte length limit on URLs.

Michael Brown 5f17089b14 pxe_netdev now holds a reference to the network device.

Autonomous generators must be genuinely autonomous (having their own

starting the retry timer immediately.

Add some debugging statements.

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.

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 7d9267561b Don't call PXENV_STOP_UNDI in the kpxeprefix. This slighy breaks the 
clean separation between loading and starting, but does mean that more
PXE stacks survive the process.
 2007-01-29 15:21:10 +00:00
Michael Brown 2cf1e33df1 Split bootsector execution code out into bootsector.c. 
Added basic El Torito ISO image boot capability

download
 2007-01-29 04:19:45 +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...

Michael Brown 9cf5c4557d Add Linux-compatible rol32/ror32 functions. Amazingly, gcc will 
optimise these down to the correct single "roll"/"rorl" instruction.

Michael Brown ebb00e032c Misread the definition of the type_of_loader field; it should include a 
version.
 2007-01-19 15:40:01 +00:00
Michael Brown 92a78c8e15 Added SIGKILL handler 2007-01-19 15:19:52 +00:00
Michael Brown 13d9a660ca Zeroing out memory before using it can be so important. 2007-01-19 14:44:59 +00:00
Michael Brown d6909f65f0 Actually, it's probably safer *not* to leave child processes hanging 
around which still hold pointers to variables belonging to our parent...
 2007-01-19 14:20:41 +00:00
Michael Brown b6194b8cb9 Note that the SIGCHLD handler could be re-entered. 2007-01-19 14:10:13 +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().

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 5ff23aa406 Include stdlib.h rather than malloc.h 2007-01-18 20:06:03 +00:00
Michael Brown d12770e254 console.h is no longer needed for debugging 2007-01-18 19:13:25 +00:00
Michael Brown 37f1b12587 Allow truly arbitrary debug levels to be specified via DEBUG= 2007-01-18 19:00:09 +00:00
Michael Brown 5d57cd47a2 Declaring the CPU architecture in the middle of an assembly file is 
somewhat redundant, and also causes gas to complain when we include
the profiling code (which uses an i586 instruction).
 2007-01-18 18:53:32 +00:00
Michael Brown f781a98ac4 Add DBGLVL_PROFILE 2007-01-18 17:59:59 +00:00
Michael Brown 05f4c3d176 Remove the one-packet-per-poll-cycle limit; it seems to no longer be 
needed now that performance is up.
 2007-01-18 16:50:35 +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 bd95927386 Accelerate memcpy() by around 32% on large, dword-aligned copies. 2007-01-18 15:18:02 +00:00
Michael Brown c8b3e969a0 Allow buffers to be pre-expanded on demand. 2007-01-18 15:13:41 +00:00
Michael Brown 6c72bf13a1 Presize the download buffer when we see the Content-Length header; 
this saves around 70us per received packet (which is around 50% of the
overall packet processing time).
 2007-01-18 13:26:57 +00:00
Michael Brown 08da93a311 Reorder functions to more closely reflect the flow of control 2007-01-18 13:10:26 +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 06630a3036 Switch from calloc() to malloc()+memset() to match the practices used 
almost everywhere else.
 2007-01-18 12:45:58 +00:00
Michael Brown 48fe701716 Respect the RX quota. This improves poll time by about 0.7us when the 
quota is 1.
 2007-01-18 12:34:12 +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.

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 f11da20f25 When a network device is specified to tcpip_tx() or it's children, treat 
it as a fallback network device rather than an explicitly forced network
device.

Clear routing table entries before re-attempting DHCP.

Michael Brown 143d14614d Quickly hack in DNS resolution as a proof of concept 2007-01-15 17:32:52 +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 afa752f5fb Protocol's get() method no longer takes ownership of the URI. HTTP is the 
exception rather than the rule; we may as well keep things clean for other
protocols.
 2007-01-15 09:18:06 +00:00
Michael Brown 1f92c6b3e8 Must free http on the error path; nothing else will do it 2007-01-15 09:08:40 +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.

Michael Brown 76aa9ad07d Make TCP give up immediately when it receives -ENETUNREACH from 
tcpip_tx().  This avoids the irritating wait when you accidentally type
"kernel pxelinux.0" before bringing up the network interface.

Add ENETUNREACH to strerror()'s list.
 2007-01-14 16:47:03 +00:00
Michael Brown c953c1a1c3 Use -ENETUNREACH to mean "no reachable network device exists, don't bother 
retrying".

Michael Brown b9f99858ab Make the getmemsize() prototype available in memsizes.h, for code that 
doesn't want to go to the hassle of processing a full memory map.

Michael Brown c1fd6e8dc7 Once image type has been set, do not autoprobe further 2007-01-14 15:25:23 +00:00
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 f92e04dea4 Add dummy "initrd" image format, just so that images can be marked as 
initrds.
 2007-01-14 15:03:39 +00:00

Michael Brown 3cbf0db0a3 Remove some references to no-longer-existent source files. 
Add a path for isolinux.bin that is correct on my system; hopefully it
will work on others too.

Michael Brown 55e6d7b70c Use debug autocolourisation. 
Shut down before jumping to the multiboot image.
 2007-01-14 00:57:43 +00:00

Michael Brown 0b0e34e667 Provide {get,set}_fbms() in basemem.h. 
set_fbms() will also update the E820 hidden region.
 2007-01-13 23:57:31 +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.

Michael Brown bd863e4112 Add header for pxe_boot() 2007-01-13 17:23:44 +00:00
Michael Brown 4b77061881 Pick up the return status code from the correct place now that we 
don't overwrite the parameter block until *after* the debug code.
 2007-01-13 16:55:57 +00:00
Michael Brown 5817c9f114 When an UNDI API call fails, print everything there is to know about it. 2007-01-13 16:53:55 +00:00
Michael Brown 3b77c7aa1b Hex dumps are now integrated into the DBG() framework. 2007-01-13 16:49:38 +00:00
Michael Brown 6a3c76c8e0 Always send EOI. We can't feasibly share interrupts (since we have no 
clue what the "previous" interrupt handler will do, which could range
from "just an iret" to "disable the interrupt"), and that means that
we have to take responsibility for ACKing all interrupts.  Joy.
 2007-01-13 14:45:26 +00:00
Michael Brown 86171c53f4 Damn Broadcom and their damned incorrect assumptions about x86 memory 
allocation.
 2007-01-13 01:48:12 +00:00
Michael Brown 341c0b9cfb Add HTTP test support 2007-01-12 19:19:59 +00:00

Michael Brown 369754f959 Whitespace fix 2007-01-12 19:17:25 +00:00
Michael Brown 63386f4455 Added ENOENT, since HTTP 404 translates to it 2007-01-12 19:14:01 +00:00
Michael Brown ca3db0bf11 Added isspace() and made strtoul() accept whitespace, as per POSIX. 2007-01-12 19:11:28 +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 bcd6ca3291 Place multiboot tables in base memory; at least some OSes won't see it 
if we don't.

Michael Brown 112d7f9d79 Code used for load buffer and multiboot image testing 2007-01-12 10:12:11 +00:00
Michael Brown 49fc8dcdc3 Use dhcp(), imgfetch() etc. to boot rather than dhcp_test(). 2007-01-12 10:08:27 +00:00
Michael Brown b45a9bfa2d Added missing declaration. 2007-01-12 10:07:56 +00:00
Michael Brown a6afbe762c Make DEBUG=script echo the commands as they are executed 2007-01-12 10:06:59 +00:00
Michael Brown 9952df9b52 Add "dhcp" command 2007-01-12 09:53:28 +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 67aedf34fa Use systematic names for XXX_IMAGE. 
Add scripts as an image format (since it's trivial to do).
 2007-01-12 09:00:48 +00:00
Michael Brown 83559c668a Don't print "<NULL>" when we use imgautoselect(). 2007-01-12 08:59:25 +00:00
Michael Brown 2be2f3b205 Rearrange struct image to reflect usage of the fields 2007-01-12 08:58:16 +00:00
Michael Brown eba3609e7f Add debug message 2007-01-12 08:57:51 +00:00

Avoid returning errors for comments and empty lines.
 2007-01-12 08:56:48 +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".

alignment.

Michael Brown e4c6418ac0 We may be required to page-align modules, so let's make sure we catch 
it if we don't.
 2007-01-12 00:09:16 +00:00
Michael Brown 7bf94b5ad6 Allow for named images. 2007-01-11 23:45:18 +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 ddbc60b5ae Whoever put together the grub multiboot.h header is insane. 2007-01-11 21:20:27 +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 200d92c76d Avoid namespace clashes 2007-01-11 19:42:26 +00:00
Michael Brown bcc98c78b8 Added fields present in the documentation but not in the header file. 2007-01-11 19:41:13 +00:00
Michael Brown dc51af59a4 Capable of starting a multiboot kernel (albeit without the multiboot 
information table yet).
 2007-01-11 18:41:15 +00:00
Michael Brown 9196e9069c Add PHYS_CODE, for use as in __asm__ ( PHYS_CODE ( ... ) ), comparable 
to the REAL_CODE interface.

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 143e3b84a4 Downloaded from current grub CVS. 2007-01-11 16:22:03 +00:00

Michael Brown 3460860bef Print informative error message when boot fails. 2007-01-11 15:26:17 +00:00
Michael Brown 230f16538f Create include/gpxe/elf.h for the ELF bits that aren't part of the ELF

 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 d9204ef676 Use physical address in debug messages; they make more sense to read. 2007-01-11 15:08:58 +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 10980c12ee Add image directory back in 2007-01-11 14:43:15 +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 ceca6b185c Added user_to_phys() and memset_user(). 2007-01-11 14:27:27 +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 c6a4055fae Add phys_to_user() and copy_user(). 2007-01-11 14:01:20 +00:00
Michael Brown fbfed96965 buffer.c should be using copy_{to,from}_user, rather than 
copy_{to,from}_phys.

Michael Brown 037da9d840 I hate NULL pointer dereferences. 2007-01-11 05:27:02 +00:00
Michael Brown 03390f0cd6 Use pkb_pad() rather than doing it the dangerous way :) 2007-01-11 05:26:16 +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 c0ef730ec4 Fix bug in buffer.c, add buffer mini-unit test. 2007-01-11 04:46:41 +00:00
Michael Brown 83fa318b86 Added strerror(0)=="No error", so that TCP protocols can use 
strerror(rc) in their closed() methods without producing "Error
0x0000" when the connection is closed normally.
 2007-01-11 04:01:31 +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 de042993c0 Warn when net device on an active route is not open. 2007-01-10 20:58:36 +00:00
Michael Brown d45c5e7ce7 Add "route" command (which currently only displays the routing table; it 
can't modify it).
 2007-01-10 20:51:14 +00:00
Michael Brown d9ba8f790b Add route() function to display routing table. 2007-01-10 20:38:20 +00:00
Michael Brown 78ded6604a Try booting from the "boot" network device first (i.e. the one which we 
were loaded from).  The code to identify this device isn't present yet,
but the code to act upon the knowledge is.
 2007-01-10 20:21:42 +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 489a4004d7 Give UNDI device a more meaningful name. 2007-01-10 05:52:04 +00:00
Michael Brown f396f1f9d3 Force ordering of commands within help list. 2007-01-10 05:13:20 +00:00
Michael Brown cef551376f Force ordering of commands in help list. 2007-01-10 05:10:30 +00:00
Michael Brown 77bb7b13a7 Having forced __table() to natural structure alignment, it now seems 
that we *can* place arrays in tables, which means we can force the
order within a table without having to resort to explicitly numbered
sections on everything.
 2007-01-10 05:08:05 +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 cc9b32c405 Remove uIP; we haven't used it for quite some time now. 2007-01-10 02:52:58 +00:00
Michael Brown 753e156844 Allow udp_{send,sendto,sendto_via} to be called outside of the 
udp_senddata() callback.  This will simplify any UDP protocols that don't
need the temporary buffer.
 2007-01-10 02:46:39 +00:00
Michael Brown 649b789e93 DHCP transmits via specified net device, so no need to create a dummy 
routing table entry just to fool ipv4.c any more.
 2007-01-10 02:37:23 +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 9869659895 Add interface management commands 2007-01-10 02:04:07 +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 e822bc2a90 Autopadding was sometimes overwriting the struct list_head at the end 
of the packet buffer.  Although pkbuffs are guaranteed to be at least
PKB_ZLEN bytes long, there's no guarantee that the data starts at the
start of the packet buffer.

Since we have to align data for rtl8139 anyway, and since the start of
the packet buffer is guaranteed to be aligned to PKB_ALIGN, we may as
well just shuffle the packet down so that it starts at the start of
the packet buffer.  This simultaneously aligns the packet and ensures
that there is enough room for the zero-padding.
 2007-01-09 21:01:55 +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 8a268073a7 Move start/stop/expire debug messages to DBG2() level. 2007-01-09 17:39:52 +00:00
Michael Brown 3c2cc59d25 Added ability to break ISR processing over several calls to poll(). 
This will allow us to implement RX quotas.
 2007-01-09 17:04:10 +00:00
Michael Brown aa7bda7b47 Send EOI after enabling interrupt, in case the device had asserted IRQ 
to the PIC while it was disabled.
 2007-01-09 14:53:19 +00:00
Michael Brown a2ffe8c123 Allow boot sector to completely destroy real-mode stack, but still 
manage to return control.
 2007-01-09 14:13:59 +00:00
Michael Brown a9369bb503 Leave protected-mode return address on PM stack when issuing a 
real_call(), rather than moving it to the RM stack and back again.
This allows the real-mode function to completely destroy the stack
contents, provided that it manages to return to real_call().
 2007-01-09 14:13:06 +00:00
Michael Brown 2eeb7c4fe7 Define "connected" as 
"when SYN is ACKed and we have already received SYN", or
  "when SYN is received and we have already had SYN ACKed"

rather than just

  "when SYN is ACKed"

This avoids spuriously calling the connected() method when we receive
a RST,ACK in response to a SYN.
 2007-01-09 05:01:22 +00:00
Michael Brown 70cc3a164a Reset character attributes before start of welcome banner, in case 
it's a serial console and remembers state from the previous program
run.
 2007-01-09 04:51:27 +00:00
Michael Brown aaca21a2b6 We can't assert that the RX engine is idle in iscsi_done(), because it 
may be called during the RX data processor, before the RX engine
transitions back to idle.  It doesn't really matter if the RX engine
isn't idle when iscsi_done() is called, because it will just pick up
where it left off on the next call.  (The same is not true for the TX
engine, so keep the TX engine assertion.)
 2007-01-09 04:42:23 +00:00
Michael Brown 6ea07b9247 Use debug auto-colourisation. 2007-01-09 04:38:39 +00:00
Michael Brown 76525294ee Clean up connection closing and permanent failure logic. 2007-01-09 04:31:33 +00:00
Michael Brown 2738bdf74b Obsoleted by drivers/net/undionly.c 2007-01-09 03:22:11 +00:00
Michael Brown d606edb41d Added UNDI root bus driver (which saves including all the PCI bus code, 
UNDI ROM code etc. when you just want a "undi.kpxe"-type image).

This driver cannot be used in conjunction with any other driver (it will
crash), or in any other format than .kpxe (it just won't find any network
devices).
 2007-01-09 03:20:22 +00:00
Michael Brown 159930862f Added missing call to undinet_remove() 2007-01-09 03:08:01 +00:00
Michael Brown 6b09dd8244 undipci_probe() has to calculate busdevfn anyway, so we may as well pass 
it directly to undi_load_pci().
 2007-01-09 02:58:07 +00:00
Michael Brown ed44e3730d Avoid erasing non-existent signatures in undi_unload() 2007-01-09 02:53:24 +00:00
Michael Brown a2be828a33 Avoid leaving preloaded_undi with invalid PXENV+/!PXE structure 
addresses if the signature checks fail.
 2007-01-09 02:52:28 +00:00
Michael Brown 697bcc9d24 Since we now always unload the base code stack (even if we keep UNDI), 
we can never return to the PXE stack and must always use INT 18.
 2007-01-09 02:46:58 +00:00
Michael Brown f2f492a536 If preloaded device matches, use that rather than going via the UNDI 
loader.
 2007-01-09 02:32:06 +00:00
Michael Brown 2436dac281 Populate preloaded_undi device when applicable. 2007-01-09 02:29:54 +00:00
Michael Brown 937289cdc8 Provide storage for an undi_device structure representing the preloaded 
UNDI stack.
 2007-01-09 02:29:18 +00:00
Michael Brown 47222d5ed8 Call PXENV_UNDI_GET_NIC_TYPE to identify NIC physical device. 
Record all information required for populating a struct undi_device.

Make debugging output more human-readable.
 2007-01-09 01:42:28 +00:00
Michael Brown cea2221737 Use fixed-width fields in struct undi_device, so that pxeprefix.S will be 
able to populate the structure.
 2007-01-09 01:41:26 +00:00
Michael Brown fbdebac5f4 Copy pxelinux's shutdown sequence: use UNLOAD_STACK without STOP_BASE, 
and call UNDI_SHUTDOWN first to make sure the NIC is in a safe state.
 2007-01-08 05:06:26 +00:00
Michael Brown 8f8af10b22 New strategy: always stop both base code and UNDI. Always free base code 
memory (unless we get an error while stopping the base code).  Leave UNDI
resident (though stopped) for .kpxe.

Still need to add code to record the device identification parameters
prior to stopping UNDI.

Michael Brown 359c888aec Remove obsolete includes 2007-01-08 02:39:56 +00:00
Michael Brown 6fc75f659b Separated out UNDI ROM location code into undirom.c, and use struct 
undi_rom rather than struct pxe_driver.  (This is part of the naming
consistency fixes).
 2007-01-08 02:38:10 +00:00
Michael Brown 675fe200e5 Use "struct undi_device" instead of "struct pxe_device", and use the 
function prefix "undinet_" and the variable name "undinic" in undinet.c,
so that we can reserve the variable name "undi" for a struct undi_device.

The idea is that we preserve the Etherboot 5.4 convention that the "UNDI"
code refers to our using an underlying UNDI stack, while the "PXE" code
refers to our providing a PXE API.
 2007-01-08 02:24:53 +00:00
Michael Brown 36c1e1aa57 Renamed undi.c to undinet.c. (undi.c will become the UNDI PCI driver) 2007-01-08 02:02:07 +00:00
Michael Brown 234d81728a Obsolete 2007-01-08 02:00:55 +00:00
Michael Brown 7b9617f5df Add device to hierarchy before calling the driver's probe() function; this 
way everything remains consistent if the probe() ends up creating child
devices.
 2007-01-08 01:29:51 +00:00
Michael Brown d3558fdd3a Remove accidentally checked-in code 2007-01-07 19:05:28 +00:00
Michael Brown 85a41b25fe Move START_UNDI, UNDI_STARTUP, UNDI_INITIALIZE and 
UNDI_GET_INFORMATION calls into drivers/net/undi.c.  undi_probe() now
gets given a pxe_device representing a PXE stack that has been loaded
into memory but not initialised in any way.
 2007-01-07 19:02:17 +00:00
Michael Brown 23cb837951 Remember to enable/disable the interrupt at the PIC. 
Handle failures in undi_open() properly.

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 ef50ea0b2b Renamed undi_net.c to undi.c. 2007-01-04 19:43:35 +00:00
Michael Brown 6cf488dcf7 Obsolete; net driver functionality is now in undi_net.c and bus driver 
functionality is now in pxebus.c.  (Not all bus functionality is ported
across yet.)
 2007-01-04 19:42:05 +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 e28db95de6 Obsolete 2007-01-04 19:37:31 +00:00

Michael Brown 70acce06e4 This file is no longer used 2007-01-04 19:36:31 +00:00
Michael Brown b12cd68726 Ripped out everything except the ability to send EOI to the PIC. 2007-01-04 19:36:18 +00:00
Michael Brown de2fc50f4c Add as a separate file so that we can do "make bin/xxxx.kpxe" rather than 
having to edit PXELOADER_KEEP_ALL as a config option.
 2007-01-04 19:35:10 +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 20681d6168 Allow empty checksums on received packets 2007-01-04 05:17:28 +00:00

call.
 2007-01-04 04:32:18 +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 d4894f0127 We *should* use the persistent reference API for our netdev reference, 
but there's so much else missing that it's not worth doing right now.

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.

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 83e1340d88 Use autocolourisation 2006-12-29 14:09:23 +00:00
Michael Brown feb4f65d1e Use auto-colourisation for debug messages. 
Truncate TX length to TCP window at time of transmission rather than at
time of adding to TX packet; this is conceptually cleaner and also allows
the application to call tcp_send() multiple times to build up a single
packet.
 2006-12-29 14:03:03 +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 be31970e36 Don't send a second FIN if we receive a FIN while in FIN_WAIT_2 2006-12-27 23:44:05 +00:00

Michael Brown 1a11cc5c5b Added times to start/stop log messages 2006-12-27 22:56:39 +00:00
Michael Brown 4cc1c1bd4c Ensure that old TCP connection state is destroyed before attempting to 
reopen connection.  (The TCP API will soon change to render this step
unnecessary.)
 2006-12-22 13:04:50 +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

Michael Brown d6f9152bfa Avoid null pointer dereferences when no username/password specified. 2006-12-21 18:38:24 +00:00
Michael Brown 6ceb55fad0 When login fails, leave the session open but not in full feature 
phase.  In iscsi_issue(), detect this state and immediately refuse the
operation.  This avoids trying multiple logins when scsi.c tries
several times to read the drive capacity.
 2006-12-21 17:43:43 +00:00
Michael Brown 024809d454 Use a bigger buffer for the initiator IQN 2006-12-21 17:42:02 +00:00

Michael Brown dbb7b30cca Return ANSI sequences for special keys 2006-12-20 23:42:28 +00:00
Michael Brown f33a03c1e5 Use getkey() and symbolic key names. 2006-12-20 22:25:54 +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 4b2b8b02ab Use symbolic key names, and avoid moving beyond end of string 2006-12-20 22:21:09 +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 b9f8599537 Define KEY_MIN and use it in kb.c. 2006-12-20 21:10:32 +00:00
Michael Brown 43d976edd0 Prevent NULL from ever pointing to some real code or data. (This was 
causing the serial console to ignore input, because it happened to end up
linked with serial_ischar() at address 0, which core/console.c decided was
invalid).
 2006-12-20 20:28:20 +00:00
Michael Brown 6ceaa158da Return -EIO when verification fails, instead of -EINVAL. 2006-12-20 14:11:50 +00:00
Michael Brown cbeec25662 settings_ui() now returns a status code. 2006-12-20 11:42:48 +00:00

Kill errortab array; it can screw up alignment.
 2006-12-20 07:57:40 +00:00

Michael Brown a6d1815bc6 Obsolete for some time now. 2006-12-20 07:05:32 +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 9ab17484d0 Explicitly call erase(), to cope with platforms where the ANSI clear 
screen sequence doesn't work (like bios_console.c on some platforms).
 2006-12-20 06:12:04 +00:00
Michael Brown f8910410fe Add attr_{get,set,on,off} as static inlines. 2006-12-20 06:06:38 +00:00

Michael Brown e4f489636f Clear message on alert row before printing new one 2006-12-20 05:03:55 +00:00
Michael Brown b93ff48173 Added descriptive text for settings and setting types, and display it in 
the option config UI.
 2006-12-20 04:58:26 +00:00
Michael Brown 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
Michael Brown fc7dcc201b Added messages for some of the most common errors 2006-12-20 03:54:20 +00:00

Michael Brown 04da3556f9 Differentiate between ENOSPC and ENOMEM 2006-12-20 03:34:27 +00:00
Michael Brown 4f506328ad Use -ENOSPC rather than -ENOMEM, to distinguish the cases "generic out of

gPXE-specific.

Michael Brown a128b33b8b The VPD engine is broken and can't actually handle placing VPD

but don't seem to be defined anywhere on the web.
 2006-12-05 15:40:28 +00:00
Michael Brown c6060a8fea Tidy up some more output. The command-line code needs some severe 
overhauling, but this is not the time to do it.
 2006-12-05 10:27:16 +00:00

Michael Brown cb883b3faf Change some debugging messages to use DBG() 2006-12-05 10:01:00 +00:00
Michael Brown 8bff0f0619 Avoid draining the keyboard buffer during gateA20_set(). It shouldn't 
technically be necessary, because the "enable A20" command requires
only that the keyboard controller is ready to accept input (i.e. that
its input buffer is empty), and shouldn't also require that the
keyboard is ready to send output (i.e. that its output buffer is also
empty).  See http://www.smsc.com/main/tools/io-bios/42i.pdf section
3.1 ("Command Invocation") for a justification.

gateA20_set() is called on every real-mode transition (in case some
idiot piece of external code such as Intel's PXE stack decided it
would be fun to re-disable A20), so draining the keyboard buffer means
that we end up losing keypresses on some systems.  In particular, this
makes typing at the command line almost impossible, and causes
Etherboot to ignore Ctrl-Alt-Del.

We should really implement a gateA20_test() function to verify that
gate A20 has been correctly enabled, and think about adding other
commonly-used methods such as Fast Gate A20.

Michael Brown 6b45947a59 Added debug statements 2006-12-04 23:20:56 +00:00
Michael Brown 052ef6dc5a Added nvs_write(). This shares a lot of code in common with nvs_read(); 
this can probably be optimised down quite a lot.
 2006-12-04 22:06:54 +00:00

device.

Separated the mechanisms of non-volatile storage access and non-volatile
stored options.
 2006-12-04 18:23:06 +00:00
Michael Brown dc06c895fc Changed length parameter in SPI methods to be a byte length, rather than 
a word length.
 2006-12-04 16:09:59 +00:00
Michael Brown 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.
 2006-12-04 15:36:51 +00:00

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

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

Michael Brown d37f82509f Added debug statements. 
Don't crash when called on an uninitialised chap structure; this
allows us to avoid extra checks within iscsi.c to make sure that we
receive the CHAP_XXX keys in a sensible order.
 2006-11-21 16:14:17 +00:00
Michael Brown a9415d3da2 Reduce from 157 to 123 bytes 2006-11-21 16:01:12 +00:00

code, rather than going through the digest layer.

Removed a spurious line of constants.

Michael Brown b16de6ae66 Inhibit compiler warnings on DBG() when building a non-debug object, 
while retaining the format string checking.
 2006-09-27 11:09:56 +00:00
Michael Brown 88e38fa148 We don't actually have a stdio.h header file. Our printf() functions are 
defined in vsprintf.h.  (This may change, since vsprintf.h is a
non-standard name, but for now it's the one to use.)

There should be no need to include vsprintf.h just for DBG() statements,
since include/compiler.h forces it in for a debug build anyway.
 2006-09-27 10:58:14 +00:00

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

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.

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.

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*

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

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

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 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.

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.

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.

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

default test to the DHCP test.
 2006-07-20 02:51:52 +00:00
Michael Brown 00a1f000b1 Added dhcp_ipv4_option() and friends.

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.

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.

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.
