b4e604aae4 PDP10, PDP11, VAX: Fix buffer overrun in dmc_attach 2016-01-05 15:37:06 -08:00
Mark Pizzolato
aa5bc9e867 DMC: Avoid using CBUFSIZE for register array data since it can vary from one platform to another. 
The consequence is that cross platform save/restore operations will fail if the CBUFSIZE is different.

73d7aee71f SCP: Add printf style format argument validation for all functions which take printf arguments. 
These include: sim_printf(), sim_messagef(), Fprint() and sim_debug().

Fix current use of these functions which had invalid arguments.

1fb209c275 SOCKETS: Cleanup, simplify and extend the sim_sock API set. 
Cleanup/Simplification by:
	1) removing irrelevant master flag variable from sim_close_sock and thus sim_err_sock
	2) change previous boolean feature arguments (datagram, nodelay, reuseaddr) to flag bits in a single option argument.  This allows for features to be added by new flag bits which don't change the calling signatures.
	3) changed all status returns to be int (vs t_stat) with success being 0 and error being -1
	4) removed unneeded simh specific type references to allow sim_sock to be used by n
Extended API by providing flags to influence socket setup/behavior:
	SIM_SOCK_OPT_REUSEADDR	Retains prior behavior when sim_switches had -U set
	SIM_SOCK_OPT_DATAGRAM	UDP socket setup provided for when prior datagram argument was specified
	SIM_SOCK_OPT_NODELAY		TCP Nagle disable provided for when prior nodelay argument was specified
	SIM_SOCK_OPT_BLOCKING	Blocking socket mode (detault is non blocking)

549779fb10 PDP10, PDP11, VAX: Adjusted KDP, DUP and DMR/DMC devices to be better behaved when the simulated system is idling. 
This may not completely fix the problem identified in issue #99, but it should help

e9b312f26a PDP11, VAX: Added Ethernet packet transmission throttling support to XQ and XU devices. 
Migrated the XQ help to the hierarchical help model.  This is a work in progress which will eventually merge much from 0readme_ethernet.txt into the device help.

6ce8d99cd8 SCP: Added generic output routine sim_printf to output to stdout and sim_log (and sim_deb when enabled) 
The goals here being to simplify calling code while getting consistent output delivered everywhere it may be useful.

Modified most places which explicitly used sim_log or merely called printf to now avoid doing that and merely call sim_printf().

1a7f8d4df0 VAX,PDP11,PDP10: Added explicit support to enable (or disable) DMR Micro Diagnostics which corresponds to the SW10 hardware switch.

ffda4c1c41 VAX,PDP11: Fix behavior of simulator when multiple DMC devices are in use concurrently. Fix for issue #51. 
The interrupt acknowledgment logic for the transmit interrupt inadvertently cleared the device interrupt pending flag even when other devices potentially had pending interrupts.

Added line specific indications in the debug output for packet trace debugging.
