Gave asynchronous operations approximate POSIX signal semantics. This

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

DHCP transmits via specified net device, so no need to create a dummy

routing table entry just to fool ipv4.c any more.
2007-01-10 02:37:23 +00:00
Michael Brown
c821a7b20d
Add udp_sendto_via() to allow e.g. DHCP to transmit without first having

Michael Brown
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
idle for a long time at the C:\ prompt and builds up a huge packet
backlog.

Rename pkb_available() to pkb_tailroom() for consistency with Linux's

Added net device TX queue; this will be needed to support the PXE UNDI API

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.

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.)

Use auto-colourisation for debug messages.
...
Truncate TX length to TCP window at time of transmission rather than at
time of adding to TX packet; this is conceptually cleaner and also allows
the application to call tcp_send() multiple times to build up a single
packet.

Michael Brown

Redefine TCP state to include "flags that have been sent" rather than
...
"flags that are currently being sent". This allows at least one special
case (checking that we haven't already sent a FIN in tcp_rx_fin()) to be
collapsed.

Cannot immediately overwrite the peer address when we parse

When login fails, leave the session open but not in full feature
...
phase. In iscsi_issue(), detect this state and immediately refuse the

A cleaner method of handling login redirection; just use the existing

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.
