Michael Brown a2e3357825 Cannot immediately overwrite the peer address when we parse 
TargetAddress from the login response, because we still need the old
address while we close the connection!

Michael Brown d6f9152bfa Avoid null pointer dereferences when no username/password specified. 2006-12-21 18:38:24 +00:00
Michael Brown 6ceb55fad0 When login fails, leave the session open but not in full feature 
phase.  In iscsi_issue(), detect this state and immediately refuse the
operation.  This avoids trying multiple logins when scsi.c tries
several times to read the drive capacity.

Michael Brown ab242a760d Add ability to shut down iSCSI connection 2006-12-21 17:17:47 +00:00
Michael Brown 38ae94f8ce A cleaner method of handling login redirection; just use the existing 
reconnection mechanism.  This avoids the problems of trying to reuse
the TCP connection structure before the old connection has cleanly exited.

Michael Brown 2497270c14 command->data_{in,out} are now userptr_t, so it is invalid to compare 
against NULL.

Michael Brown ea5fa82b91 Fixed variable name in assertion 2006-08-10 17:09:48 +00:00
Michael Brown d0e4f198d6 Add iSCSI to the DHCP tests. 
Start updating iscsi.c to use Nikhil's TCP API.
 2006-08-07 16:48:24 +00:00
Michael Brown 3a660f9b25 Update ftp.c and hello.c to use the generic async_operations API. 2006-06-19 15:46:58 +00:00
Michael Brown 8637834031 Made the temporary buffer part of the TCP senddata() API, to ease the 
transition away from uIP.

Prepared ipv4.c for transition away from uIP.
 2006-06-17 23:20:54 +00:00
Michael Brown f743de4858 Added tcp_kick(). This speed up LILO and GRUB booting by almost two 
orders of magnitude.
 2006-05-27 19:01:20 +00:00
Michael Brown b9cbae58fa Expert advice tells me that we *do* have to explicitly state the 
options even when we want to use the defaults.
 2006-05-19 17:50:49 +00:00
Michael Brown d48d0fb1bb Add the concept of a "user pointer" (similar to the void __user * in 
the kernel), which encapsulates the information needed to refer to an
external buffer.  Under normal operation, this can just be a void *
equivalent, but under -DKEEP_IT_REAL it would be a segoff_t equivalent.

Use this concept to avoid the need for bounce buffers in int13.c,
which reduces memory usage and opens up the possibility of using
multi-sector reads.

Extend the block-device API and the SCSI block device implementation
to support multi-sector reads.

Update iscsi.c to use user buffers.

Move the obsolete portions of realmode.h to old_realmode.h.

MS-DOS now boots an order of magnitude faster over iSCSI (~10 seconds
from power-up to C:> prompt in bochs).

Michael Brown c69c1ec540 Documented login parameters that we negotiate. 2006-05-19 00:31:42 +00:00
Michael Brown a280587cde iSCSI writes seem to be working (at least, the ethereal trace shows no 
errors; still need to verify data integrity).

SCSI response PDUs are handled: status and sense data (if available) are
returned via the scsi_command structure.

Updated iSCSI session parameter usage.
 2006-05-19 00:20:08 +00:00
Michael Brown 813a052dc3 Set ErrorRecoveryLevel=0 (we don't want to have to handle it). 2006-05-17 17:41:50 +00:00
Michael Brown f25731d08f Split "iSCSI as a SCSI device" out from "iSCSI as a TCP protocol". 2006-05-14 23:29:16 +00:00

Michael Brown 2462047128 Typo 2006-04-30 18:19:39 +00:00
Michael Brown 9e1becaf8a Merge TCP aborted(), timedout() and closed() methods into a single 
closed() method with a reason code.

Michael Brown 8afb6303fb Half-way tidy 2006-04-30 15:23:29 +00:00
Michael Brown 04b6a1e004 Make all TCP methods optional; at least FTP data is a read-only 
connection and so legitimately ignores acked() and senddata().
