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.

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

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).

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

Tidy up 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

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 
retrying".

ad22cccc09 No need to maintain a received byte count; we always fill in sequential 
order so we can just use buffer->fill.

0010e10ef3 Update TFTP to use a struct buffer rather than a callback. 
Add debug autocolourisation to TFTP.

dad5274522 Add "name" field to struct device to allow human-readable hardware device 
names.

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).

cc9b32c405 Remove uIP; we haven't used it for quite some time now. 2007-01-10 02:52:58 +00:00
Michael Brown
753e156844 Allow udp_{send,sendto,sendto_via} to be called outside of the 
udp_senddata() callback.  This will simplify any UDP protocols that don't
need the temporary buffer.

649b789e93 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 
to set up dummy routing entries.
 2007-01-10 02:31:38 +00:00

f008b77ba2 Allow an explicit network device to be specified for IP-layer 
transmissions.

98b6154c3e Add "name" field to network device, to facilitate netdev commands. 2007-01-09 23:48:18 +00:00

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.

18e5353bed Rename pkb_available() to pkb_tailroom() for consistency with Linux's 
skb_tailroom().  Add pkb_headroom().

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).

Added debug autocolourisation to netdevice.c

8a268073a7 Move start/stop/expire debug messages to DBG2() level. 2007-01-09 17:39:52 +00:00

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.)
