a2f9bf70d7 [pxe] Display PXE_LOADER debug message after call to initialise() 
At least one Dell system calls the UNDI loader entry point with the
BIOS console disabled.  The serial console is active only after a call
to initialise(), so move the debug message in undi_loader() so that it
can be displayed via the serial console.

ca0b0f0616 [relocate] Guard against systems that report empty memory regions 
If the INT 15,e820 memory map reports a region [0,0), this confuses
the "truncate to even megabytes" logic, which ends up rounding the
region 'down' to [0,fff00000).

Fix by ensuring that the region's end address is at least 1, before we
subtract 1 to obtain the "last byte in region" address.

0e408658b9 [iscsi] Change default initiator name prefix to "iqn.2000-01.org.etherboot:" 
The domain etherboot.org was actually registered on 2000-01-09, not
2000-09-01.  (To put it another way, it was registered on 1/9/2000 (US
date format) rather than 1/9/2000 (sensible date format); this may
illuminate the cause of the error.)

"iqn.2000-09.org.etherboot:" is still valid as per RFC3720, but may be
surprising to users, so change it to something less unexpected.

Thanks to the anonymous contributor for pointing this one out.

6df82b1a9d [undi] Scan for UNDI ROMs on 512-byte boundaries rather than 2kB boundaries 
Apparently some BIOSes will place option ROMs on 512-byte boundaries.
While this is against specification, it doesn't actually hurt
anything, so we may as well increase our scan granularity to 512
bytes.

Wyse Streaming Manager server (WLDRM13.BIN) assumes that the PXENV+

Add a dummy entry point at UNDI_CS:0000, which just jumps to the
correct entry point.

320b072c7a [pcbios] Support arbitrary splits of the e820 memory map 
Allow for an arbitrary number of splits of the system memory map via
INT 15,e820.

Features of the new map-mangling algorithm include:

  Supports random access to e820 map entries.

  Requires only sequential access support from the underlying e820
  map, even if our caller uses random access.

  Empty regions will always be stripped.

  Always terminates with %ebx=0, even if the underlying map terminates
  with CF=1.

  Allows for an arbitrary number of hidden regions, with underlying
  regions split into as many subregions as necessary.

Total size increase to achieve this is 193 bytes.

9737095d49 [pcbios] Prepare for multiple splits of hidden e820 memory regions 
Define a list of N allowed memory regions, and split each underlying
e820 region into up to N subregions.  Strip resulting empty regions
out of the map, avoiding using the "return with CF set to strip last
empty region" trick, because it seems that bootmgr.exe in Win2k8 gets
upset if the memory map is terminated with CF set.

This is an intermediate checkin that defines a single allowed memory
region covering the entire 64-bit address space, and uses the existing
map-mangling code on top of the new region-splitting code.  This
sanitises the memory map to the point that Win2k8 is able to boot even
on a system that defines a final zero-length region at the 4GB mark.

I'm checking this in because it may be useful for future debugging
efforts to be able to run with the existing and known-working map
mangling code together with the map sanitisation capabilities of the
new map mangling code.

23bca8f9d8 [util] Allow Option::ROM to understand and modify initialisation entry point 
Add support for manipulating the jump instruction that forms the
option ROM initialisation entry point, so that mergerom.pl can treat
it just like other entry points.

Add support for merging the initialisation entry point (and IBM BOFM
table) to mergerom.pl; this is another slightly icky but unfortunately
necessary GPL vs. NDA workaround.  When mergerom.pl replaces an entry
point in the original ROM, it now fills in the corresponding entry
point in the merged ROM with the original value; this allows (for
example) a merged initialisation entry point to do some processing and
then jump back to the original entry point.

8f8f5acf09 [settings] Avoid overwriting the start of .text in fetch_string_setting() 
fetch_string_setting() was subtracting one from the length of the
to-be-NUL-terminated buffer in order to obtain the length of the
unterminated buffer to be passed to fetch_setting().  This works
extremely well unless the length of the to-be-NUL-terminated buffer is
zero, at which point we end up giving fetch_setting() a buffer of
length -1UL, thereby inviting it to overwrite as much memory as it
wants...

a1d0f6ed2e [dhcp] Do not restrict minimum retry time for ProxyDHCPREQUEST 
The ProxyDHCPREQUEST is a unicast packet, so the first request will
almost always be lost due to not having the IP address in the ARP
cache.  If the minimum retry time is set to one second (as per commit
ff2b6a5), then ProxyDHCP will time out and give up before managing to
successfully transmit a request.

The DHCP timers need to be reworked anyway, so this mild hack is
acceptable for now.

f178436bb1 [pxe] If no ProxyDHCPACK exists, use DHCPACK for the fake ProxyDHCPACK packet 
WinPE seems to have a bug that causes it to always use the TFTP server
IP address and filename from the ProxyDHCPACK packet, even if the
ProxyDHCPACK packet doesn't exist.  This causes it to end up
attempting to fetch a file such as

  tftp://0.0.0.0/bootmgr.exe

If we don't have a ProxyDHCPACK to use, we pretend that it was a copy
of the DHCPACK packet.  This works around the problem, and hopefully
won't surprise any NBPs.

481a21798d [autoboot] Retain initial-slash (if present) when constructing TFTP URIs 
When we boot from a DHCP-supplied filename, we previously relied on
the fact that the current working URI is set to tftp://[next-server]/
in order to resolve the filename into a full tftp:// URI.  However,
this process will eliminate the distinction between filenames with and
without initial slashes:

 cwuri="tftp://10.0.0.1/" filename="vmlinuz"  => URI="tftp://10.0.0.1/vmlinuz"
 cwuri="tftp://10.0.0.1/" filename="/vmlinuz" => URI="tftp://10.0.0.1/vmlinuz"

This distinction is important for some TFTP servers.  We now
explicitly construct a string of the form

 "tftp://[next-server]/filename"

so that a filename with an initial slash will result in a URI
containing a double-slash, e.g.

 "tftp://10.0.0.1//vmlinuz"

The TFTP code always strips a single initial slash, and so ends up
presenting the correct path to the server.

URIs entered explicitly by users at the command line must include a
double slash if they want an initial slash presented to the TFTP
server:

  "kernel tftp://10.0.0.1/vmlinuz"  => filename="vmlinuz"
  "kernel tftp://10.0.0.1//vmlinuz" => filename="/vmlinuz"

  In my testing with "qemu -net user" the 226 response to RETR was

  this caused the received file to become truncated without any error
  indication.  Fix this by adding an intermediate state FTP_TRANSFER
  between FTP_RETR and FTP_QUIT, so that the transfer is considered to
  be complete only when both the end of data connection is encountered
  and the final reply to the RETR command is received.

On the plus side, the fact that shutdown() now takes flags to

another ugly hack (to allow returning via the PXE stack on BIOSes that

Conjecture: The hardware issues 64-bit DMA writes of status descriptors,
which some PCI bridges seem to split into two 32-bit writes in reverse
order (i.e. dword 1 first).  This means that we sometimes observe a
partial status descriptor.  Add an explicit check to ensure that the
descriptor is complete before processing it.

Also ensure that the RDS consumer counter is incremented only when we
know that we have actually consumed an RX descriptor.

bb41ec385c [int13] Pairwise swap drive numbers, instead of shifting all drive numbers 
Shifting all INT13 drive numbers causes problems on systems that use a
sparse drive number space (e.g. qemu BIOS, which uses 0xe0 for the CD-ROM
drive).

The strategy now is:

  Each drive is assigned a "natural" drive number, being the next
  available drive number in the system (based on the BIOS drive count).

  Each drive is accessed using its specified drive number.  If the
  specified drive number is -1, the natural drive number will be used.

  Accesses to the specified drive number will be delivered to the
  emulated drive, masking out any preexisting drive using this number.

  Accesses to the natural drive number, if different, will be remapped to
  the masked-out drive.

The overall upshot is that, for examples:

  System has no drives.  Emulated INT13 drive gets natural number 0x80
  and specified number 0x80.  Accesses to drive 0x80 go to the emulated
  drive, and there is no remapping.

  System has one drive.  Emulated INT13 drive gets natural number 0x81
  and specified number 0x80.  Accesses to drive 0x80 go to the emulated
  drive.  Accesses to drive 0x81 get remapped to the original drive 0x80.

0436e417bc [image] Fail "imgexec"/"boot" if the image to execute is ambiguous 
If there is more than one loaded image, refuse to automatically select
the image to execute.  There are at least two possible cases, with
different "correct" answers:

1. User loads image A by mistake, then loads image B and types "boot".
   User wants to execute image B.

2. User loads image A, then loads image B (which patches image A), then
   types "boot".  User wants to execute image A.

If a user actually wants to load multiple images, they must explicitly
specify which image is to be executed.

Clearing the LOADED flag actually prevents users from doing clever things

This commit implements GDB over UDP.  Using UDP is more complex than
serial and has required some restructuring.

The GDB stub is now built using one or both of GDBSERIAL and GDBUDP
config.h options.

To enter the debugger, execute the gPXE shell command:
gdbstub <transport> [<options>...]

Where <transport> is "serial" or "udp".  For "udp", the name of a
configured network device is required:
gdbstub udp net0

The GDB stub listens on UDP port 43770 by default.

Send a null command, specifically "pulse outputs" with no outputs

thought it was inherent.  Therefore, there are systems out there (e.g. HP

null command, 0xFF, written to port 0x64 at the end of the A20 toggling

Some drivers that still use the legacy-driver wrapper (tg3 in particular)

Note that this provides only 16-byte alignment; it is not possible to
request alignment to any greater than 16 bytes using
__attribute__((aligned)), since the relocation code will preserve only 16
byte alignment (and operation under -DKEEP_IT_REAL cannot preserve more
that 16 byte alignment).

requesting only a single range per NACK; if the missing-block list is

blocks.

50810955e9 [console] Call cpu_nap() only if there is no input waiting 
Avoid calling cpu_nap() until after we have determined that there is
no input ready to read.  This avoids delaying for one timer interrupt
(~50ms) in the case of

  if ( iskey() )
     char = getkey()

which happens to be present in monojob.c, which is where we spend most
of our time looping (e.g. during any download).

This should eliminate the irritating tendency of gPXE to lose
keypresses.

Discovered on a Dell system where the serial port seems to send in a
constant stream of 0xff characters; this wouldn't be a problem in
itself except that each one triggers the 50ms delay (as mentioned
above), which really kills performance.

5d36ec6721 [slam] Implement SLAM flow control 
On any fast network, or with any driver that may drop packets
(e.g. Infiniband, which has very small RX rings), the traditional
usage of the SLAM protocol will result in enormous numbers of packet
drops and a consequent large number of retransmissions.

By adapting the client behaviour, we can force the server to act more
like a multicast TFTP server, with flow control provided by a single
master client.

This behaviour should interoperate with any traditional SLAM client
(e.g. Etherboot 5.4) on the network.  The SLAM protocol isn't actually
documented anywhere, so it's hard to define either behaviour as
compliant or otherwise.

77a5cc6b13 [ELF] Add ability to boot ELF images generated by wraplinux and mkelfImage 
Delete ELF as a generic image type.  The method for invoking an
ELF-based image (as well as any tables that must be set up to allow it
to boot) will always depend on the specific architecture.  core/elf.c
now only provides the elf_load() function, to avoid duplicating
functionality between ELF-based image types.

Add arch/i386/image/elfboot.c, to handle the generic case of 32-bit
x86 ELF images.  We don't currently set up any multiboot tables, ELF
notes, etc.  This seems to be sufficient for loading kernels generated
using both wraplinux and coreboot's mkelfImage.

Note that while Etherboot 5.4 allowed ELF images to return, we don't.
There is no callback mechanism for the loaded image to shut down gPXE,
which means that we have to shut down before invoking the image.  This
means that we lose device state, protection against being trampled on,
etc.  It is not safe to continue afterwards.

f866b17998 [util] config-local.h to avoid accidental commits 
During development it is often handy to change the config.h options from
their defaults, for example to enable debugging features.

To prevent accidental commits of debugging config.h changes, mdc
suggested having a config-local.h that is excluded from source control.
This file acts as a temporary config.h and can override any of the
defaults.

This commit is an attempt to implement the config-local.h feature.

The config.h file now has the following as its last line:
/* @TRYSOURCE config-local.h */

The @TRYSOURCE directive causes config-local.h to be included at that
point in the file.  If config-local.h does not exist, no error will be
printed and parsing will continue as normal.  Therefore, mkconfig.pl is
"trying" to "source" config-local.h.

Respond to zero-length TCP keepalives (i.e. empty data packets
transmitted outside the window).  Even if the peer wouldn't otherwise
expect an ACK (because its packet consumed no sequence space), force an
ACK if it was outside the window.

We don't yet generate TCP keepalives.  It could be done, but it's unclear
what benefit this would have.  (Linux, for example, doesn't start sending
keepalives until the connection has been idle for two hours.)

224 or greater, it gets treated as multicast address and a ethernet
multicast address is sent out on the wire causing timeouts

00ed567069 [iSCSI] Offer CHAP authentication only if we have a username and password 
Some EMC targets will fail if we advertise that we can authenticate with
CHAP, but the target is configured to allow unauthenticated access to that
target.  We advertise AuthMethod=CHAP,None; the target should (I think)
select AuthMethod=None for unprotected targets.  IETD does this, but an
EMC Celerra NS83 doesn't.

Fix by offering only AuthMethod=None if the user hasn't supplied a
username and password; this means that we won't be offering CHAP
authentication unless the user is expecting to use it (in which case the
target is presumably configured appropriately).

Many thanks to Alessandro Iurlano <alessandro.iurlano@gmail.com> for
reporting and helping to diagnose this problem.

1ba959c6b3 [NETDEV] Add notion of link state 
Add ability for network devices to flag link up/down state to the

Autobooting code will now wait for link-up before attempting DHCP.

IPoIB reflects the Infiniband link state as the network device link state
(which is not strictly correct; we also need a succesful IPoIB IPv4
broadcast group join), but is probably more informative.

3475b693b7 [HCI] Display "Not an executable image" when appropriate 
PXE is a catch-all image format with no signature checks.  If an
unsupported image file is loaded, it will be treated as a PXE image.  In
most cases, the image will be too large to be loaded as a PXE image (which
has to fit in base memory), so the error returned to the user will be that
the segment could not fit within the memory region.

Add an explicit check to pxe_image.c to reject images larger than base
memory with ENOEXEC.

Add ENOEXEC to the error string table.

b107637008 [http] gPXE is a HTTP/1.0 client, not a HTTP/1.1 client 
gPXE is not compliant with the HTTP/1.1 specification (RFC 2616),
since it lacks support for "Transfer-Encoding: chunked".  gPXE is,
however, compliant with the HTTP/1.0 specification (RFC 1945), which
does not require "Transfer-Encoding: chunked" to be supported.

The only HTTP/1.1 feature that gPXE uses is the "Host:" header, but
servers universally accept that one from HTTP/1.0 clients as an
optional extension (it is obligatory for HTTP/1.1).  gPXE does not,
for example, appear to support connection caching.  Advertising as a
HTTP/1.0 client will typically make the server close the connection
immediately upon sending the last data, which is actually beneficial
if we aren't going to keep the connection alive anyway.

aa74a7d53c [DHCP] Add support for ProxyDHCP requests 
The PXE spec is (as usual) unclear on precisely when ProxyDHCPREQUESTs
should be issued.  We adapt the following, slightly paranoid approach:

  If an offer contains an IP address, then it is a normal DHCPOFFER.

  If an offer contains an option #60 "PXEClient", then it is a
  ProxyDHCPOFFER.  Note that the same packet can be both a normal
  DHCPOFFER and a ProxyDHCPOFFER.

  After receiving the normal DHCPACK, if we have received a
  ProxyDHCPOFFER, we unicast a ProxyDHCPREQUEST back to the ProxyDHCP
  server on port 4011.  If we time out waiting for a ProxyDHCPACK, we
  treat this as a non-fatal error.

fc9f016be0 UNDI ISR: save and restore 32-bit registers 
As written, if the if the UNDI ISR call clobbers the upper halves of
any of the GPRs (which by convention it is permitted to do, and by
paranoia should be expected to do) then nothing in the interrupt
handler will recover the state.

Additionally, save/restore %fs and %gs out of sheer paranoia - it's a
cheap enough operation, and may prevent problems due to poorly written
UNDI stacks.

9d4e4dbc32 3c90x driver fix (legacy) from Geert Staapers 
From: Geert Stappers <stappers@stappers.nl>
To: etherboot-developers@lists.sourceforge.net
Subject: [Etherboot-developers] 3c90x polling again [patch]
Date: Thu, 29 Nov 2007 09:22:36 +0100
User-Agent: Mutt/1.5.16 (2007-06-11)

Hello,

gPXE didn't work on 3COM 905C Tornado cards for me.
It did transmit the DHCP request, but it didn't see the DHCP offer.

Adding debug print statements allready solved the problem.
Attached is a patch that has a cleaner delay then print statements.
The core of it is
-    for(i=0;i<40000;i++);
+    mdelay(1);

There was no research if the change is about a longer delay
or about code NOT being optimized away. It works for me   :-)

Cheers

1d7974182e Overwrite the device descriptor's IRQ number with whatever the legacy 
driver's probe() routine fills in in nic->irqno.  This is so that
non-interrupt-capable legacy drivers which set nic->irqno=0 will end
up reporting IRQ#0 via PXENV_UNDI_GET_INFORMATION; this in turn means
that the calling PXE NBP will (should) hook the timer interrupt, and
everything will sort of work.

bd2607305c Correct e1000 interrupt routine to enable on 1 disable on 0. duh. 
The e1000_irq() routine should (per mcb30) do enable on non-zero,
disable on zero.  This is not consistent in all drivers, so I'll
wait to update it when doing a global sweep.
 2007-12-13 11:20:45 -05:00
Marty Connor
1a867bfb39 Remove *_fill_nic() calls, and directly set nic->ioaddr and nic->irqno . 
This needs to be done manually because if the irq() routine is
implemented then we want something like "nic->irqno = pci->irqno;",
else we do "nic->irqno = 0;" nic->ioaddr may also need to be set
carefully.

Also added local variables to end of many files, for emacs indentation
to match kernel style (tab does 8 space indent).

2c7a9e803c Remove the (unused) option to override _prefix_link_addr,

A bug in some versions of ld causes segfaults if the DEFINED() macro
is used in a linker script *and* the -Map option to ld is present.

We don't currently need to override any of these values; if we need to
do so in future then the solution will probably be to always specify
the values on the ld command line, and have the linker script not
define them at all.

c194b0c4bf Work around a bug in the OpenSolaris iSCSI target. 
We didn't specify values for MaxRecvDataSegmentLength and
MaxBurstLength (to save space, since we were happy with the
RFC-defined default values of 8kB and 256kB respectively).  However,
the OpenSolaris target (incorrectly) assumes default values of zero
for these parameters.

The upshot was that the OpenSolaris target would get stuck in an
endless loop trying to send us the first 512-byte sector, zero bytes
at a time, and would eventually run out of memory and core-dump.

Fixed by explicitly specifying the default values for these two
parameters.

byte, rather than the number of permissible bytes (i.e. subtract one
from the value under the previous definition to get the value under
the new definition).

This avoids integer overflow on 64-bit kernels, where
bzhdr.initrd_addr_max may be 0xffffffffffffffff; under the old
behaviour we set mem_limit equal to initrd_addr_max+1, which meant it
ended up as zero.  Kernel loads would fail with ENOBUFS.

functions with __attribute__((cdecl)) to compensate for this.

(Note: we cannot mark with with __cdecl, because we define __cdecl to
incorporate regparm(0) as well.)

02a7514128 Change #warning to FIXME for ns8390.c 
This driver really needs to be rewritten.
It tries to build both ISA and PCI images,
and makes life diffifult for the build system
and rom-o-matic.net.  The warning was just a reminder
that it needs to be cleaned up and re-factored
to split the PCI and ISA drivers.

bug report by someone who actually has this card.

number of (potentially very slow) gateA20_set operations.

Die with a fatal error if we are unable to set gate A20; if this fails
then we are bound to experience memory corruption at a later stage,
and I'd prefer to pick it up early.

efd322091d Set up %ds *before* testing a value in our data segment (d'oh!). 
Always send EOI; do not chain to BIOS's default interrupt handler.
They are just too unpredictable; at least VMware's seems to kill the
machine if you go anywhere near it.

Disable interrupts after return from PXENV_UNDI_ISR, just in case some
dumb PXE stack enables them.

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

longer enable or disable IRQs.

to implementing correct interrupt-masking behaviour in pxe_undi.c.

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.

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.

dad5274522 Add "name" field to struct device to allow human-readable hardware device

Add "dev" pointer in struct net_device to tie network interfaces back to a

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).

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

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.

a9369bb503 Leave protected-mode return address on PM stack when issuing a

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.)

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.

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

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

collapsed.

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

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.

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 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.

7de5d32ff5 cmdlinelib.c now calls system() rather than doing its own tokenisation

38ae94f8ce A cleaner method of handling login redirection; just use the existing

the TCP connection structure before the old connection has cleanly exited.

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.

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.

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.

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).

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

nonblocking (with completion via async_wait()).

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.

83d80d9e79 Remove references to obsoleted REAL_CALL from documentation. 2006-05-24 09:16:48 +00:00
Michael Brown
3b525385af Removed REAL_FRAGMENT and REAL_CALL, and left just REAL_EXEC (which is 
the only one we actually use).  This allows REAL_EXEC fragments to
contain proper references to constraints (e.g. "%w0"), rather than having
to force the use of specific registers.

Note that the "num_constraints" parameter is now completely obsolete, and
that we can probably reduce the syntax to something like
  __asm__ __volatile__ ( REAL_CODE ( "asm statements" )
                         : output constraints
                         : input constraints
                         : clobber );
which would look much more natural, and avoid the need to always specify
a clobber list.

5ec2b2c251 Cope with regions bigger than 4GB. 
We now split e820 regions around ourselves, rather than just
truncating the e820 region.  This avoids the worst-case scenario of
losing all memory over 4GB.

It's more important to get the memory map right now that we're
expecting to still be loaded when the OS starts in several situations
(e.g. Linux with UNDI driver, any OS with iSCSI/AoE boot, etc.).

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).

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.)

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).

f99e7a375e At least cope with "%llx" by reading the correct-sized va_arg from the

At some point, vsprintf() needs to be fixed up so that it can correctly
cope with limited-sized buffers (i.e. vsnprintf), long longs, and
standard format specifiers (e.g. "%04x").  We should also remove the
special types (MAC addresses and IP addresses).  This would then enable
us to use gcc's ability to type-check printf format strings.

fdb983d473 Preserve the whole of %esp across prot_call(). We have to split this 
between the low half stored in the static variable rm_sp, and the high
half stored on the prot_call() stack, because:

  Just using the stack would screw up when a prot_call()ed routine
  executes a real_call(); it would have no way to find the current top of
  the RM stack.

  Extending rm_sp to rm_esp would not be safe, because the guarantee that
  rm_sp must return to the correct value by the time an external
  real-mode call returns applies only to %sp, not to %esp.

a42092d2a0 Add a temporary snprintf, so that safely-written code can at least 
compile, even if it won't yet be safe.

Michael Brown
bac97eb979 Change semantics of network API so that packet-absorbing calls *always* 
take ownership of the packet, rather than doing so only if they return
success.  This breaks semantic compatibility with Linux's
hard_start_xmit() method, but means that we don't have to worry so much
about error cases.

Split mechanism of processing received packets (net_rx_process()) out
from policy (net_step()), preparatory to putting net_step() in a separate
object.

d8e99bf28f Gave up on adding POSIX errno's as required, and just added (almost) all 
of them in one go.

EBADIMG has been replaced by ENOEXEC, and EIMGRET by ECANCELED.

cf3783b4ca Actually, it's probably a good idea to have packet buffers avoid 4kB 
crossings.

face774c4c Fixed erroneous comparison 2006-04-25 11:54:58 +00:00
Michael Brown
95f8a42930 Removed incorrect comment; malloc() is inefficient only when the 
alignment and size are both powers of two, and there's no way to
specify an alignment through the malloc() interface anyway.
 2006-04-25 10:41:49 +00:00
Michael Brown
4e92f29c9e Now passes trivial tests. free_memblock() needs neatening up. 2006-04-25 04:01:58 +00:00
Michael Brown
b601a7d355 Updated memory allocator to improve support for unaligned or partially 
aligned blocks.

Moved header to include/malloc.h, since we now also provide the
POSIX-like malloc()/free() pair.

Not yet tested.
 2006-04-25 03:30:46 +00:00
Michael Brown
2f0d412210 Add __constant_flsl(), because it's useful for finding out the next 
power-of-two up from a given constant via
  ( 1 << fls ( constant - 1 ) )

fls(), flsl(), ffs() and ffsl() appear in strings.h according to
POSIX.

fcf765e42d Add missing {register,free}_netdev(). 
Tie into existing driver API; we'll fix that up soon.
 2006-04-24 18:44:50 +00:00
Michael Brown
832e86246b gcc is rather over-aggressive about optimising out static data structures 
even when __atribute__ (( unused )) is correctly set...
 2006-04-24 18:31:37 +00:00
Michael Brown
4c4e4de18f (librm_base-1b) is already an offset; no need to apply OFFSET(). 
Doing so, in fact, seems to expose an assembler bug; (a-b-0) is
apparently not the same as (a-b).  Go figure.
 2006-04-24 18:29:47 +00:00
Michael Brown
824d6ffa7f Header rearrangement. 
I want to get to the point where any header in include/ reflects a
standard user-level header (e.g. a POSIX header), while everything that's
specific to gPXE lives in include/gpxe/.  Headers that reflect a Linux
header (e.g. if_ether.h) should also be in include/gpxe/, with the same
name as the Linux header and, preferably, the same names used for the
definitions.

53f78346bf Network API now allows for multiple network devices (although the 
implementation allows for only one, and does so without compromising on
the efficiency of static allocation).

Link-layer protocols are cleanly separated from the device drivers.

Network-layer protocols are cleanly separated from individual network
devices.

Link-layer and network-layer protocols are cleanly separated from each
other.

e323d1a29b Add "net" directory. 
Avoid including debug information in bin/%.s output, since the whole
point is to have easy-to-read assembler.
 2006-04-24 15:20:01 +00:00
Michael Brown
6209bd873a First sketch of a new net device API. 2006-04-19 12:07:46 +00:00
Michael Brown
bdc8190c8d Remove the concept of the media-independent link-layer header and replace 
it with metadata in the pkb structure.  This is required since UNDI will
want to be able to parse the link-layer header without destroying it.
 2006-04-19 11:32:24 +00:00
Michael Brown
b89ccac02d Updated to remove obsolete constants 2006-04-19 02:11:56 +00:00
Michael Brown
3ca7dbe7ca Added the concept of a network interface (a network-layer concept) as 
separate from a network device (a link-layer concept).

d65a66606b Typo 2006-04-19 02:08:27 +00:00
Michael Brown
2558439ce4 First version, based on include/linux/list.h, stripped down to just 
those functions we are likely to need.

Still need to come up with a way of getting the linker to create
static lists using this linking mechanism.
 2006-04-19 02:05:50 +00:00
Michael Brown
d24042f0bb Update now that if_ether.h has moved. 2006-04-19 01:56:10 +00:00

Michael Brown
744b895077 Make flags more efficient. 
Add 'raw' net_addr facility (needed for ARP).
 2006-04-19 01:53:49 +00:00
Michael Brown
49f933fbc3 Moved if_ether.h and if_arp.h to include/gpxe, for consistency with Linux 
kernel.

Removed obsolete struct arprequest from if_arp.h and put it in nic.c so
that nic.c will still compile.  ARP will very shortly be handled by
net/arp.c instead.
 2006-04-19 01:52:41 +00:00
Michael Brown
9f67ad9db0 First version. ARP protocol independence in less than the size of uIP's 
Ethernet-and-IPv4-only ARP module.  :)
 2006-04-19 01:43:56 +00:00
Michael Brown

Michael Brown
0864a73347 First version, based on the concepts in linux/skbuff.h 2006-04-18 17:47:01 +00:00
Michael Brown
1a60444fe4 Added netmask and gateway global options. 
Added iSCSI testing.
 2006-04-05 11:46:18 +00:00
Michael Brown
6446767258 First draft of iSCSI protocol support. Is capable of retrieving disk 
blocks.
 2006-04-05 11:44:56 +00:00
Michael Brown
9ea782d339 Make pcap_inject non-static, so that its prototype doesn't conflict with 
the real pcap_inject in the case where we do have it.
 2006-04-05 11:44:05 +00:00
Michael Brown
c8a7133e9f Added tcp_buffer, to give applications a zero-cost place to build data to 
be transmitted.
 2006-04-05 11:43:01 +00:00
Michael Brown
988bb50979 Added set_netmask() and set_gateway() 2006-04-05 11:41:15 +00:00
Michael Brown
ee058362fa We don't need to know anything about ARP 2006-03-24 17:39:05 +00:00
Michael Brown
90892d5ec7 Allow specifying the local IP address via --from. 2006-03-24 17:28:40 +00:00
Michael Brown
b44332eb7d Split non-TCP portions of the stack out into ip.[ch]. 
Added set_ipaddr().
 2006-03-24 17:22:09 +00:00
Michael Brown
1c607470e3 Put in a substitute pcap_inject() function, since earlier versions of 
libpcap are lacking the function.  For now, we always use the
substitute version, since there's no easy way to determine whether or
not we need it.
 2006-03-24 16:43:12 +00:00
Michael Brown
7e61f38799 Moved "hello world" protocol implementation out of prototester.c and into 
the first standalong uIP-based protocol module.
 2006-03-23 22:37:05 +00:00
Michael Brown
508dcdb303 Added container_of(). This seems about the best place to put it, since 
the definition of it uses offsetof(), and the two concepts are related.
 2006-03-23 22:07:21 +00:00
Michael Brown
99032becce Pick up the gPXE include files when building prototester. 2006-03-23 21:35:20 +00:00
Michael Brown
2299435f1c Added prototype for inet_ntoa, even though we don't have the function 
yet, in order to allow prototester.c to compile.  It might be worth
changing all the uses of "%@" in printf to use "%s" and inet_ntoa
instead, in order to improve the portability of our code.
 2006-03-23 21:34:25 +00:00
Michael Brown
a4a0244aa3 Moved uIP wrapper out of prototester.c and into proto/tcp.c. 2006-03-23 21:32:03 +00:00
Michael Brown
17c0253ca0 Add include/gpxe as a directory to scan. 
Exclude proto/uip, since uip.c and uip_arp.c both have global variables
called "c", which screws up doxygen's auto-generation of links to file
documentation when it encounters a file name such as "hello.c".
 2006-03-23 21:06:36 +00:00
Michael Brown
2bc7c746a6 Updated with "doxygen -u" from doxygen 1.4.4 2006-03-23 20:39:26 +00:00
Michael Brown
05b284399e Moved old tcp.h to old_tcp.h, to avoid name clash with new (uIP-based) 
tcp.h.
 2006-03-23 20:34:08 +00:00
Michael Brown
af23ff8a24 Assertions are now handled via the POSIX-like <assert.h>. 2006-03-23 19:33:57 +00:00
Michael Brown
55497b3402 Added missing #endif 2006-03-23 19:23:25 +00:00
Michael Brown
cb8e89de15 Added assert.h, with assert() defined (almost) as per POSIX, and 
linker_assert() defined as gPXE-specific.
 2006-03-23 17:28:51 +00:00
Michael Brown
531371efa2 Removed to make way for the uIP-based tcp.c. 2006-03-23 16:59:25 +00:00
Michael Brown
dde1c5ad18 Moved include/in.h to include/gpxe/in.h, so that it can be included by 
prototester.
 2006-03-23 16:45:01 +00:00
Michael Brown
eaf40883ff Add Makefile for hijack and prototester utilities. 2006-03-23 13:11:41 +00:00
Michael Brown
21c58729ae Add debug symbols to objects. (They will be stripped out of the final 
-Obinary build anyway, so it doesn't waste any space).
 2006-03-23 13:09:29 +00:00
Michael Brown
b2c94b32fc Make the application state a void *. 2006-03-23 13:08:06 +00:00

218c26ff2b Can now also print data sent by the remote side. 2006-03-23 13:06:08 +00:00
Michael Brown
0d506a5c6a Now capable of sending "Hello world!" via TCP. 2006-03-23 12:25:28 +00:00
Michael Brown
911486fe41 Added basic http-specific option parsing 2006-03-22 22:35:32 +00:00
Michael Brown
5263a5abf4 Started adding structure to allow for separate protocol tests, with 
individual options.

Created the embryonic beginnings of a cleanly separated driver and
protocol stack API.
 2006-03-22 21:25:35 +00:00
Michael Brown
c32e83ad8d Skeleton version: contains device driver (connecting to network via 
hijack daemon) and a functional but very ugly and very primitive
wrapper around uIP.

This passes proof-of-concept testing; it successfully initiates a TCP
connection and responds to pings.
 2006-03-22 02:23:20 +00:00
Michael Brown
bb37bd47f8 Added from uip-0.9/uip/uip_arp.[ch] 2006-03-22 02:14:55 +00:00

Michael Brown
1c7c24f21f Basic, functional-but-extremely-pessimal versions (taken from

Michael Brown
e072baeb8c Use libpcap API to send/receive packets. 
Include automatic filtering (based on source MAC address of first
transmitted packet).

Proven to successfully elicit a ping response from a remote host.
 2006-03-21 16:50:25 +00:00
Michael Brown
4485df516c Basic structure in place: can daemonise, listen on a Unix domain 
socket, accept new connections, open a network interface using libpcap
and forward (all) traffic.
