8bb9f726a0 When an async operation dies, orphan its children. 2007-01-18 22:36:57 +00:00

075f8144ff Have DHCP set the nameserver, rather than DNS read the DHCP nameserver 
value.

c014f607a8 Use total free memory as advertised window. This seems to be sufficient 
to avoid drops even on slow NICs.

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.

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).

05f4c3d176 Remove the one-packet-per-poll-cycle limit; it seems to no longer be 
needed now that performance is up.

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).

35776f481c Don't always zero memory in malloc(). This saves around 2us on a 
full-length PKB allocation.

06630a3036 Switch from calloc() to malloc()+memset() to match the practices used 
almost everywhere else.

48fe701716 Respect the RX quota. This improves poll time by about 0.7us when the 
quota is 1.

dd6d94004f HTTP/DNS now working fully asynchronously. HTTP/IP addresses and any 
other protocol won't work at the moment.

protocols by URI scheme.

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.

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.

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.

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.

a5a330339b Split DBG() statement containing two inet_ntoa() statements; they 
return a static buffer.

Michael Brown
ce7289a766 Dump buffer and packet information in PXENV_UDP_READ as well 2007-01-14 18:22:37 +00:00
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".

8edf8f6fa8 Add the "initrd" command 2007-01-14 16:09:48 +00:00
Michael Brown
a5f6408d8e We can now load an initrd as well as a kernel 2007-01-14 16:09:01 +00:00
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.

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.

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.

Shut down before jumping to the multiboot image.
 2007-01-14 00:57:43 +00:00
Michael Brown
dca369ddc3 Call hide_etherboot() from startup(), rather than requiring the prefix to 
do it.
 2007-01-14 00:53:56 +00:00
Michael Brown
c2708df14a Make shutdown functions callable by OS image's exec methods. 2007-01-14 00:16:41 +00:00

Michael Brown
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.

f11900a9c6 I prefer IMAGE_XXX to XXX_IMAGE. 
Add IMAGE_PXE to use the new image format framework.  "kernel pxelinux.0"
now works.

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.

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.

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

address, to work around OS bugs.

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

48e0fc3447 API change: the raw image will no longer be (hypothetically) discarded 
after a call to load().

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

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.

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).
