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.

5e4e267177 Start restructuring pxe_tftp.c to cope with multicast (MTFTP) receives. 2008-02-02 15:59:32 +00:00
Michael Brown
c9c8cdeb8b Add pxe_set_cached_filename() so that pxe_tftp.c can also update the 
stored DHCP packets.

84f99f781e Use XFER_INIT() macro. 2008-01-22 18:50:24 +00:00

f6a8158eed Make seek information part of the xfer metadata, rather than an entirely 
separate xfer method.

Add missing .alloc_iob entries to several xfer_interface_operations
structures.

6b0e147e0d Don't complain when callers provide too-short buffers for 
PXENV_GET_CACHED_INFO.  NTLDR does this.

838ecba131 Provide individually cached constructed copies of DHCP packets via 
PXENV_GET_CACHED_INFO.  If we dont do this, Altiris' NBP screws up; it
relies on being able to grab pointers to each of the three packets and
then read them at will later.

3a2473f123 Do not fill in the BufferLimit field in struct 
s_PXENV_GET_CACHED_INFO, because this field doesn't exist in earlier
versions of the PXE spec, and some callers don't allocate space for it.

b34d4d0449 Separate the "is data ready" function of xfer_seek() into an 
xfer_window() function, which can return a scalar rather than a
boolean.

ca4c6f9eee Kill off unused request() method in data-xfer interface. 2007-07-08 02:10:54 +01:00

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.

30a442aef8 Report our interface type as "gPXE" to avoid working around Etherboot 
5.4 bugs when driving ourselves via UNDI.

1ce0b4bbfb Kill off PXENV_UNDI_FORCE_INTERRUPT support; we have no reason to 
suspect that we need it, and implementing it would require needlessly
complicating the net device API.

5f92f0bd82 Reserve space for link-layer header in pxenv_undi_transmit() when not 
handed a P_UNKNOWN packet.

258afef751 Add missing call to free_iob() in pxenv_undi_isr().

4968caab82 Add trivial net device statistics (TX and RX packet count), reported 
via UNDI API and also by ifstat command; may be useful for debugging.

e42eba4af4 Use a common base-memory packet buffer for DHCP construction (as used 
by PXE and NBI) and UNDI packets (as used by undinet and UNDI).

5f17089b14 pxe_netdev now holds a reference to the network device. 
Use generic fields in struct device_description rather than assuming
that the struct device * is contained within a pci_device or
isapnp_device; this assumption is broken when using the undionly
driver.

Add PXENV_UNDI_SET_STATION_ADDRESS.

e3bbfd7a75 Call shutdown() from pxenv_undi_shutdown(). Probably not totally 
correct, but it's enough to get RIS working.

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.

84a2b886e1 Split error-message table portions of errno.h out to gpxe/errortab.h 2006-12-20 03:40:48 +00:00

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.

6ac78f6aff added stdio.h to includes for DBG compilation 2006-09-27 05:57:06 +00:00
