Make all TCP methods optional; at least FTP data is a read-only
...
connection and so legitimately ignores acked() and senddata().

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

Fix up prototype of strtoul() to match POSIX.

Make tcp_connect() void; it will eventually have no failure case.

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.

Fix a couple of broken assertions, and align the buffer correctly.
2006-04-28 14:09:31 +00:00

Transmit the buffer contents, not the buffer descriptor...

Add an explicit failure debug message
2006-04-28 14:07:41 +00:00

Exclude bin directory from tags generation.

Create something that might be usable as a symbol list for bochs'
internal debugger.

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EBADIMG has been replaced by ENOEXEC, and EIMGRET by ECANCELED.
2006-04-28 13:44:34 +00:00

Hardcoded paths to ../../src/bin avoid one step in the instructions.

Avoid the need for a symlink to the BIOS directory; just use the locally

checked-out copy.

Much safer to use a TAP device statically allocated with tunctl.

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

Fixed erroneous comparison

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

Now passes trivial tests. free_memblock() needs neatening up.
2006-04-25 04:01:58 +00:00
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
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.

Add missing {register,free}_netdev().

Tie into existing driver API; we'll fix that up soon.

gcc is rather over-aggressive about optimising out static data structures

even when __atribute__ (( unused )) is correctly set...

(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

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.

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.
