7d9267561b Don't call PXENV_STOP_UNDI in the kpxeprefix. This slighy breaks the 
clean separation between loading and starting, but does mean that more
PXE stacks survive the process.

c42a384709 Moved most buffer debug messages to DBG2. 
Make expand_buffer() a non-inline function, so that we can add debug
messages.

Expandable buffers now don't *always* round up to the next power of two.
This allows e.g. loading a 137MB ISO image on a machine with only 256MB
RAM...

6c72bf13a1 Presize the download buffer when we see the Content-Length header;

ff8528ea9a Create and use async_block() macro; it cuts down on the visual overhead

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.

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

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.

77bb7b13a7 Having forced __table() to natural structure alignment, it now seems 
that we *can* place arrays in tables, which means we can force the

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
hardware device.

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.

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.

b7fcfe8ece Added net device TX queue; this will be needed to support the PXE UNDI API 
(which will need us to wait for TX completions).

a9369bb503 Leave protected-mode return address on PM stack when issuing a 
real_call(), rather than moving it to the RM stack and back again.
This allows the real-mode function to completely destroy the stack
contents, provided that it manages to return to real_call().

2eeb7c4fe7 Define "connected" as 
"when SYN is ACKed and we have already received SYN", or
  "when SYN is received and we have already had SYN ACKed"

rather than just

  "when SYN is ACKed"

This avoids spuriously calling the connected() method when we receive
a RST,ACK in response to a SYN.

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.)

d606edb41d Added UNDI root bus driver (which saves including all the PCI bus code, 
UNDI ROM code etc. when you just want a "undi.kpxe"-type image).

This driver cannot be used in conjunction with any other driver (it will
crash), or in any other format than .kpxe (it just won't find any network
devices).

8f8af10b22 New strategy: always stop both base code and UNDI. Always free base code 
memory (unless we get an error while stopping the base code).  Leave UNDI
resident (though stopped) for .kpxe.

Still need to add code to record the device identification parameters
prior to stopping UNDI.

 2007-01-08 02:38:10 +00:00
Michael Brown
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.
 2007-01-08 02:24:53 +00:00
