Michael Brown aec9b8a41b [Settings] Use a settings applicator to configure IPv4 routes. 2008-03-21 00:01:27 +00:00
Michael Brown cf03304620 [Settings] Introduce settings applicators. 
Convert DHCP option applicators in dns.c and iscsi.c to settings
applicators.

Kill off DHCP option applicators.
 2008-03-20 23:15:48 +00:00
Michael Brown acfa14423e [Settings] Add per-netdevice settings block 
Add a configuration settings block for each net device.  This will
provide the parent scope for settings applicable only to that network
device (e.g. non-volatile options stored on the NIC, options obtained via
DHCP, etc.).

Expose the MAC address as a setting.

Michael Brown 844828cb15 [DHCP] Fix RFC4390 client identifier constructions. 
RFC 4390 provides for the DHCP client identifier to contain the link-layer
hardware type and MAC address when the MAC address exceeds 16 bytes.
However, the hardware type field is only 8 bits; we were assuming 16 bits.
 2008-02-27 16:55:46 +00:00
Michael Brown bc3f0a25c6 [Infiniband] Add preliminary support for multi-port devices. 
Arbel and Hermon cards both have multiple ports.  Add the
infrastructure required to register each port as a separate IB
device.  Don't yet register more than one port, since registration
will currently fail unless a valid link is detected.

Use ib_*_{set,get}_{drv,owner}data wrappers to access driver- and
owner-private data on Infiniband structures.
 2008-02-27 13:59:56 +00:00
Michael Brown 6570203571 [Infiniband] Centralise MAD operations 
Pull out common code for handling management datagrams from arbel.c
and hermon.c into infiniband.c.

Add port number to struct ib_device.

Add open(), close() and mad() methods to struct ib_device_operations.

Michael Brown 563955ce37 [Infiniband] Add missing list_del()s in ib_create_qp() failure path. 2008-02-23 10:48:10 +00:00
Michael Brown 428c6342bc Fixes for EqualLogic iSCSI targets: 
Allow port numbers in iSCSI redirection.

  Wait for SCSI status, not just the final data-in (which may be followed
  by an explicit SCSI Response PDU if the S bit is not set).
 2008-02-07 22:46:26 +00:00
Michael Brown 122abb50af Merge branch 'master' of rom.etherboot.org:/pub/scm/gpxe 2008-01-22 18:53:01 +00:00
Michael Brown f6a8158eed Make seek information part of the xfer metadata, rather than an entirely 
separate xfer method.

Add missing .alloc_iob entries to several xfer_interface_operations
structures.
 2008-01-08 16:46:55 +00:00
Michael Brown 3311169707 When the DHCP file/sname fields are empty, don't allow them to override 
their equivalent DHCP-option-specified values.
 2008-01-07 13:50:32 +00:00

Michael Brown 1949641d10 Fix compiler warnings that appear only on OpenBSD. 2007-12-06 14:16:46 -06:00
Michael Brown 798f7f6b8e Kill off some warnings-problematic debug statements in ndp.c; the code 
is non-functional anyway.
 2007-12-07 01:51:08 +00:00

Michael Brown f770744ee0 Quick hack to be able to accept transfers from servers that don't 
supply options.
 2007-11-25 16:06:29 +00:00
Michael Brown b3abf25e3c Allow DHCP server to instruct gPXE to ignore ProxyDHCP (which will 
also avoid waiting for ProxyDHCP offers).

Also reduce the ProxyDHCP timeout, because it's already irritating me.
 2007-11-21 22:10:04 +00:00
Michael Brown 0becbf5fba Add ProxyDHCP support. 2007-11-21 21:51:43 +00:00
Michael Brown fb809da2df Remove some assumptions about DHCP obtaining only a single options block. 2007-11-21 04:48:18 +00:00
Michael Brown 8d18338ae7 Add PXE-required DHCP options to DHCPDISCOVER and DHCPREQUEST packets. 2007-11-21 03:57:30 +00:00
Michael Brown 26f3a09ccf Add UUID to DHCP request as option 97 (if available). 2007-11-21 03:29:53 +00:00
Michael Brown c194b0c4bf Work around a bug in the OpenSolaris iSCSI target. 
We didn't specify values for MaxRecvDataSegmentLength and
MaxBurstLength (to save space, since we were happy with the
RFC-defined default values of 8kB and 256kB respectively).  However,
the OpenSolaris target (incorrectly) assumes default values of zero
for these parameters.

The upshot was that the OpenSolaris target would get stuck in an
endless loop trying to send us the first 512-byte sector, zero bytes
at a time, and would eventually run out of memory and core-dump.

Fixed by explicitly specifying the default values for these two
parameters.
 2007-11-05 13:29:05 +00:00
Michael Brown 2303c45d65 Force a netdevice poll in net_tx() before attempting to transmit 
packet, to work around the problem whereby small TX rings get backed
up because we haven't yet poll()ed for TX completions.
 2007-10-04 14:46:56 +01:00
Michael Brown 267a4483ab Added an almost obscene amount of debugging and assertion code while 
tracking down a bug that turned out to be a free_iob() used where I
needed a netdev_tx_complete().  This left the freed I/O buffer on the
net device's TX list, with bad, bad consequences later.

Also fixed the bug in question.
 2007-09-17 19:01:10 +01:00
Michael Brown 387a1a8556 Minor debug message improvement. 2007-09-17 18:57:32 +01:00

Michael Brown b21d4ca21e Revert to dev_priv/owner_priv scheme, rather than container_of; it 
makes it easier to put the generic allocation code into infiniband.c
 2007-09-16 17:25:15 +01:00
Michael Brown 37fc40bc8c post_recv() now works, and we can pass data on the IPoIB queue pair 
using entirely our own code.
 2007-09-15 23:33:25 +01:00

fixed; still using a quick hack-up just to be able to pass through
data.
 2007-09-13 14:43:12 +01:00
Michael Brown 7e4e5af462 Use RFC4390 whenever hardware address exceeds 16 bytes; this allows us 
to construct DHCP packets suitable for Infiniband.

Michael Brown 1311b4194c Eliminate PF_INET; just use the AF_INET from the struct sockaddr instead. 2007-05-26 20:41:23 +00:00
Michael Brown b8618d76db Modify data-xfer semantics: it is no longer necessary to call one of 
request(), seek() or deliver_xxx() in order to start the data flow.
Autonomous generators must be genuinely autonomous (having their own
process), or otherwise arrange to be called.  TCP does this by
starting the retry timer immediately.

Add some debugging statements.
 2007-05-26 15:04:36 +00:00
Michael Brown 3601103381 Modify process semantics; rescheduling is now automatic. 
Add reference-counting to processes.

Add timer_running() test.

Anselm Martin Hoffmeister ff5aac826a hoffmeis: Fixing situation where absence of a newdata() handler for UDP 
connections might break things. Only-sending applications like syslog()
do not need a newdata() handler, so added a check if that handler exists.
 2007-04-09 17:34:10 +00:00
Michael Brown 520d9c36af Updated ISAPnP, EISA, MCA and ISA buses to current device model. 
ISA 3c509 is currently non-functional, although the EISA (3c509-eisa) and
MCA (3c529) variants should build OK.

None of this code is yet tested.

Michael Brown 075f8144ff Have DHCP set the nameserver, rather than DNS read the DHCP nameserver 
value.
 2007-01-18 21:22:03 +00:00
Michael Brown c014f607a8 Use total free memory as advertised window. This seems to be sufficient 
to avoid drops even on slow NICs.
 2007-01-18 20:39:17 +00:00
Michael Brown 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.
 2007-01-18 20:11:04 +00:00
Michael Brown 5ff23aa406 Include stdlib.h rather than malloc.h 2007-01-18 20:06:03 +00:00
Michael Brown 05f4c3d176 Remove the one-packet-per-poll-cycle limit; it seems to no longer be 
needed now that performance is up.
 2007-01-18 16:50:35 +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).

it as a fallback network device rather than an explicitly forced network
device.

Clear routing table entries before re-attempting DHCP.

Michael Brown 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.

Michael Brown 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.
 2007-01-15 08:49:10 +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".

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

Michael Brown 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).
 2007-01-10 04:22:09 +00:00
Michael Brown 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.
 2007-01-10 02:46:39 +00:00
Michael Brown 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
Michael Brown f008b77ba2 Allow an explicit network device to be specified for IP-layer 
transmissions.

Michael Brown d24b80acf2 Added network interface management commands 2007-01-10 01:55:07 +00:00
Michael Brown 98b6154c3e Add "name" field to network device, to facilitate netdev commands. 2007-01-09 23:48:18 +00:00
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.
 2007-01-09 21:47:01 +00:00
Michael Brown 18e5353bed Rename pkb_available() to pkb_tailroom() for consistency with Linux's 
skb_tailroom().  Add pkb_headroom().
 2007-01-09 20:56:31 +00:00
Michael Brown 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
 2007-01-09 20:18:31 +00:00
Michael Brown 8a268073a7 Move start/stop/expire debug messages to DBG2() level. 2007-01-09 17:39:52 +00:00
