Michael Brown 83617e5b1c [DHCP] Save precious packet-aligned memory by copying DHCP responses 
Copy DHCP responses to a standard malloc()ed buffer, rather than
retaining the I/O buffer that they arrived in.
 2008-03-26 12:25:59 +00:00
Michael Brown 96edbd128f [PXEXT] Avoid queueing zero-length buffers in posix_io.c 
read_user() assumes that zero-length buffers don't exist, and optimises
around this.
 2008-03-25 21:10:21 +00:00
Michael Brown 92d15eff30 [Settings] Remove assumption that all settings have DHCP tag values 
Allow for settings to be described by something other than a DHCP option
tag if desirable.  Currently used only for the MAC address setting.

Separate out fake DHCP packet creation code from dhcp.c to fakedhcp.c.

Remove notion of settings from dhcppkt.c.

Rationalise dhcp.c to use settings API only for final registration of the
DHCP options, rather than using {store,fetch}_setting throughout.

Michael Brown ee5bdb0d75 [PXEXT] Avoid returning a false EOF when we have an empty buffer queued 2008-03-25 20:29:42 +00:00
Michael Brown 7234f91bf8 [DHCP] Fix DHCP state confusion. 
DHCP code was using an incorrect check for whether to construct a
DHCPDISCOVER or DHCPREQUEST packet.
 2008-03-25 16:38:01 +00:00
Michael Brown 8f00c84828 [Settings] Add named setting for next-server 
It's probably easier to have a named setting for next-server, rather
than to explain to people why they need to pretend it is option 175.3.
 2008-03-24 00:48:06 +00:00
Michael Brown c06e6d0635 [Makefile] Use -MM instead of -M in dependency generation 
Using -MM strips out any system header files from the dependency list,
which means that we could safely use an external stdarg.h if we wanted
to.
 2008-03-24 00:28:55 +00:00
Michael Brown dbf8a02e8f [libc] Use __builtin_va_list et al in stdarg.h 
The home-grown versions don't work properly for static variadic
functions, when gcc can choose to use a non-standard calling convention.

Michael Brown ee4206a8a7 [DHCP] Fix up fake-packet creation as used by PXENV_GET_CACHED_INFO 
Add dedicated functions create_dhcpdiscover(), create_dhcpack() and
create_proxydhcpack() for use by external code such as the PXE preboot
code.

Register ProxyDHCP options under the global scope "proxydhcp".

Unregister previously-acquired DHCP and ProxyDHCP settings when DHCP
succeeds.

Michael Brown acfa14423e [Settings] Add per-netdevice settings block 
Add a configuration settings block for each net device.  This will
provide the parent scope for settings applicable only to that network
device (e.g. non-volatile options stored on the NIC, options obtained via
DHCP, etc.).

Expose the MAC address as a setting.
 2008-03-20 21:06:53 +00:00
Michael Brown 260b93bb72 [Settings] Add settings hierarchy 
Add the notion of the settings hierarchy, complete with
register/unregister routines.

Rename set->store and get->fetch to avoid naming conflicts with get/put
as used in reference counting.
 2008-03-20 21:01:32 +00:00
Michael Brown a48b4d9948 [Settings] Start revamping the configuration settings API. 
Add the concept of an abstract configuration setting, comprising a (DHCP)
tag value and an associated byte sequence.

Add the concept of a settings namespace.

Add functions for extracting string, IPv4 address, and signed and
unsigned integer values from configuration settings (analogous to
dhcp_snprintf(), dhcp_ipv4_option(), etc.).

Update functions for parsing and formatting named/typed options to work
with new settings API.

Update NVO commands and config UI to use new settings API.

Michael Brown 070cbebc26 [Timers] Initialise timers on first use 
Timers are sometimes required before the call to initialise(), so we
cannot rely on initialise() to set up the timers before use.

Michael Brown 03398e3389 [Settings] Allow encapsulated options to be specified as named settings 
Allow encapsulated options to be specified as e.g. "175.3".  As a
side-effect, change the separator character for the type field from "." to
":"; for example, the IP address pseudo-option is now "175.3:ipv4".
 2008-03-18 04:13:11 +00:00
Michael Brown e2613e8896 [Settings] Add int16, int32 and hex-string configuration setting types 
Add parse and display routines for 16-bit and 32-bit integer configuration
settings.

Add parse and display routines for hex-string configuration settings.

Assume hex-string as a configuration setting type if no type is explicitly
specified.

Michael Brown 6fe585642a [libc] Fix a validation bug in strtoul() 
strtoul() was accepting the characters immediately above ASCII 0..9 as
valid hex digits, due to a missing comparison.

Michael Brown 5a08b434c7 [Settings] show_setting() functions return snprintf()-style length. 
show_setting() and related functions now return an "actual length" in the
style of snprintf().  This is to allow consumers to allocate buffers large
enough to hold the formatted setting.

Minor bugfix: 4 x 2 = 8, not 16
 2008-03-11 16:08:04 +00:00
Michael Brown 3bf7105cab [prefix] Cope with image source addresses outside base memory 
When PMM is used, the gPXE image source will no longer be in base memory.
Decompression of .text16 and .data16 can therefore no longer be done in
real mode.
 2008-03-11 13:26:46 +00:00
Michael Brown 9c86a39551 [PXE] Improve PnP/BBS detection 
Use BBS installation check to see if we need to hook INT19 even on a PnP
BIOS.

Verify that $PnP signature is paragraph-aligned; bochs/qemu BIOS provides
a dummy $PnP signature with no valid entry point, and deliberately
unaligns the signature to indicate that it is not properly valid.

Print message if INT19 is hooked.

Attempt to use PMM even if BBS check failed.

Michael Brown 1dd3f88964 [PXE] Work around a buffer-size bug in WinPE 
WinPE's pxeboot.n12 takes the BufferLimit returned by gPXE (indicating
the size of gPXE's internal DHCP packet buffers) and erroneously passes
it in as BufferSize (indicating the size of pxeboot.n12's DHCP packet
buffer).  If these don't match, then pxeboot.n12 ends up instructing gPXE
to overwrite parts of its data segment.

Change gPXE's internal DHCP packet buffers to be exactly
sizeof(BOOTPLAYER_t) bytes to work around this problem.
 2008-03-10 11:46:55 +00:00
Michael Brown 12f203c606 [PXE] Add PMM support to romprefix.S (untested) 
ROM initialisation vector now attempts to allocate a 2MB block using
PMM.  If successful, it copies the ROM image to this block, then
shrinks the ROM image to allow for more option ROMs.  If unsuccessful,
it leaves the ROM as-is.

ROM BEV now attempts to return to the BIOS, resorting to INT 18 only
if the BIOS stack has been corrupted.

Michael Brown fad35829eb [Makefile] Use bin/VVVVDDDD.rom instead of bin/pci_VVVV_DDDD.rom 
The generate-by-PCI-device-ID rules (bin/pci_VVVV_DDDD.rom) are generally
used for building actual ROM images to be burned, and the burning
utilities generally run under some DOS variant.  Change the filename from
pci_VVVV_DDDD.rom to VVVVDDDD.rom so that it is compatible with the DOS
8.3-character filename limit.

Michael Brown b62f2325ba [PXEXT] Add PXENV_FILE_EXEC call to PXE extensions API. 
This allows pxelinux to execute arbitrary gPXE commands.  This is
remarkably unsafe (not least because some of the commands will assume
full ownership of memory and do nasty things like edit the e820 map
underneath the calling pxelinux), but it does allow access to the
"sanboot" command.

Alexey Zaytsev 4006d229e5 Introduce the new timer subsystem. 
Timer subsystem initialization code in core/timer.c

	Split the BIOS and RTDSC timer drivers from i386_timer.c

	Split arch/i386/firmware/pcbios/bios.c into the RTSDC
	timer driver and arch/i386/core/nap.c

	Split the headers properly:
		include/unistd.h - delay functions to be used by the
					gPXE core and drivers.

		include/gpxe/timer.h - the fimer subsystem interface
					to be used by the timer drivers
					and currticks() to be used by
					the code gPXE subsystems.

		include/latch.h	- removed
		include/timer.h - scheduled for removal. Some driver
					are using currticks, which is
					only for core subsystems.

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

Michael Brown 5172d7b266 Autodetect whether or not we need to be using -fno-stack-protector. 2007-12-15 19:37:21 +00:00
Michael Brown 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.
 2007-12-15 19:32:32 +00:00
Marty Connor 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).

Michael Brown 2c7a9e803c Remove the (unused) option to override _prefix_link_addr, 
_textdata_link_addr, _load_addr and _max_align in the linker scripts.
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.

Michael Brown 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.

Michael Brown 56550e400e Redefine bzimage_exec_context::mem_limit to be the highest permissible 
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.
