Michael Brown b94420a52b Ready to start testing 2007-07-08 22:01:49 +01:00
Michael Brown edd1b173a7 Code in place to use a hypothetical SCSI interface. 2007-07-08 19:33:26 +01:00
Michael Brown f2fa390ae6 Everything except the SCSI interface should now be present 2007-07-08 18:51:56 +01:00
Michael Brown 9b28b25332 iSCSI updated to use data-xfer interface on the socket side (TCP). 
SCSI interface not yet implemented.
 2007-07-08 16:04:13 +01:00
Michael Brown edded7546e Limit xmit window to one MTU. (Path MTU discovery not yet 
implemented; should be done at some point.)
 2007-07-08 14:33:53 +01:00
Michael Brown 237e23c1c9 Add debug message when nameserver setting is applied/changed via DHCP. 2007-07-08 14:31:51 +01:00
Michael Brown 35afb379af TCP limits advertised TCP window to size of application window 
obtained via xfer_window().
 2007-07-08 14:14:59 +01:00
Michael Brown b34d4d0449 Separate the "is data ready" function of xfer_seek() into an 
xfer_window() function, which can return a scalar rather than a
boolean.
 2007-07-08 14:11:07 +01:00
Michael Brown ca4c6f9eee Kill off unused request() method in data-xfer interface. 2007-07-08 02:10:54 +01:00
Michael Brown 4c418d2100 Use net_device_operations structure and netdev_nullify() to allow for 
safe dropping of the netdev ref by the driver while other refs still
exist.

Add netdev_irq() method.  Net device open()/close() methods should no
longer enable or disable IRQs.

Remove rx_quota; it wasn't used anywhere and added too much complexity
to implementing correct interrupt-masking behaviour in pxe_undi.c.

Michael Brown 934b70d62c Apply global DHCP options when register_dhcp_options() is called. Do 
not apply DHCP options in dhcp_configure_netdev().
 2007-07-06 17:07:50 +01:00
Michael Brown 1567b69895 Add concept of DHCP option applicators. 2007-07-05 18:38:14 +01:00

Michael Brown 8156f6bd19 Switch compiler warning on tcp_open() to a #warning 2007-07-05 12:00:35 +01:00
Michael Brown a5f33ea283 Added missing line to set return status code. 2007-07-03 21:22:12 +01:00
Michael Brown fd86c819ba Use a linker-table based system to automatically mark and start up 
permanent processes, rather than requiring each one to have its own
initialisation function.

Michael Brown 5b52630a9c Never attempt to route the broadcast address. 2007-07-03 13:55:45 +01:00
Michael Brown 4968caab82 Add trivial net device statistics (TX and RX packet count), reported 
via UNDI API and also by ifstat command; may be useful for debugging.

Michael Brown 3bf5eb49d0 Can't use strncpy() to copy strings that aren't NUL-terminated to 
begin with.
 2007-07-01 03:22:28 +01:00
Michael Brown acd598b4f9 Don't build option-overloaded packets; they just confuse people (ISC 
DHCPD and Windows RIS in particular).
 2007-06-30 01:32:53 +01:00
Michael Brown c73bff7ae5 Set current working URI based on TFTP server specified by DHCP. 2007-06-28 21:22:25 +01:00
Michael Brown d465ae9785 Bugfix: iobuf->data always points to the start of the allocated 
portion, not to the bit we want to currently write to...
 2007-06-28 18:38:50 +01:00
Michael Brown 5de837cc67 Mildly ugly hack to force correct linkage. 2007-06-28 18:06:25 +01:00

Michael Brown cf33b568dc Forgot to set initial session state. Now works! 2007-06-28 01:55:01 +01:00
Michael Brown 73fe1ba9dd Kill off job::start() (it was only ever added as part of an aborted 
attempt at triggering TCP-related protocols to start).
 2007-06-28 01:09:45 +01:00
Michael Brown 07dc294de8 Update DHCP to use data-xfer interface (not yet tested). 2007-06-27 23:20:36 +01:00
Michael Brown f77815f2b1 Kill off hotplug.h and just make net devices normal reference-counted 
structures.

DHCP still broken and #if 0'd out.
 2007-06-27 14:48:31 +01:00
Michael Brown e381714c07 Partial migration of UDP to data-xfer interface. (Will not link at 
present; DHCP is broken).
 2007-06-20 01:13:35 +01:00
Michael Brown 2d4c72b762 Remove unused headers. 2007-06-11 23:40:34 +01:00

Michael Brown 01b4bde8a0 Updated TFTP and PXE UDP API code to use not-yet-implemented data-xfer 
UDP API.
 2007-06-11 18:11:29 +01:00
Michael Brown 95adce0ce1 Add concept of transfer metadata, to be used by UDP in order to 
implement sendto()/recvfrom() equivalents.
 2007-06-11 15:04:39 +01:00
Michael Brown 6f0a6c09db Merge branch 'master' into mcb-tcp-xfer 2007-06-08 16:33:24 +01:00
Michael Brown 335b99a39d Move [v]ssnprintf() from iscsi.c into vsprintf.c; we need them 
elsewhere as well.
 2007-05-31 13:26:50 +00:00
Michael Brown 4ccd1e8198 Should call ftp_done() if constructor fails. 2007-05-29 15:37:30 +00:00

Michael Brown 63719deea9 Introduce name resolution interface and named socket opener. 2007-05-27 01:07:00 +00:00
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.
 2007-05-26 15:00:56 +00:00
Michael Brown 1136c19fa4 Updated tcp.c to provide a standardised data transfer interface. 2007-05-25 15:58:42 +00:00
Michael Brown 776357214e Rename pkbpad.c to iobpad.c 2007-05-19 18:42:27 +00:00

Anselm Martin Hoffmeister ed7dc02a95 hoffmeis: Preparations for syslog support (LOGSERVER in DHCP, linewise 
output buffering defintions and the like)
 2007-04-09 18:01:43 +00:00
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 4e3976711d A working name resolution framework 2007-01-18 22:38:13 +00:00
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).
 2007-01-18 13:26:57 +00:00
Michael Brown 08da93a311 Reorder functions to more closely reflect the flow of control 2007-01-18 13:10:26 +00:00
Michael Brown 06630a3036 Switch from calloc() to malloc()+memset() to match the practices used 
almost everywhere else.
 2007-01-18 12:45:58 +00:00
Michael Brown dd6d94004f HTTP/DNS now working fully asynchronously. HTTP/IP addresses and any 
other protocol won't work at the moment.
 2007-01-18 03:39:45 +00:00
Michael Brown 99e58865c7 Use struct sockaddr rather than struct sockaddr_tcpip 
Tidy up code
 2007-01-18 03:35:00 +00:00
Michael Brown 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.

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
