[x86_64] Fix assorted 64-bit compilation errors and warnings

2008-11-19T19:33:05+00:00

Remove various 32-bit assumptions scattered throughout the codebase. The code is still not necessarily 64-bit clean, but will at least compile.

[settings] Add the notion of a "tag magic" to numbered settings

2008-10-30T21:47:14+00:00

Settings can be constructed using a dotted-decimal notation, to allow for access to unnamed settings. The default interpretation is as a DHCP option number (with encapsulated options represented as ".". In several contexts (e.g. SMBIOS, Phantom CLP), it is useful to interpret the dotted-decimal notation as referring to non-DHCP options. In this case, it becomes necessary for these contexts to ignore standard DHCP options, otherwise we end up trying to, for example, retrieve the boot filename from SMBIOS. Allow settings blocks to specify a "tag magic". When dotted-decimal notation is used to construct a setting, the tag magic value of the originating settings block will be ORed in to the tag number. Store/fetch methods can then check for the magic number before interpreting arbitrarily-numbered settings.

[tftp] Add EUNIQ_xx values to differentiate the many EINVAL errors

[dhcp] Accept BOOTP as well as DHCP

[dhcp] Do not restrict minimum retry time for ProxyDHCPREQUEST

2008-08-13T20:51:53+00:00

The ProxyDHCPREQUEST is a unicast packet, so the first request will almost always be lost due to not having the IP address in the ARP cache. If the minimum retry time is set to one second (as per commit ff2b6a5), then ProxyDHCP will time out and give up before managing to successfully transmit a request. The DHCP timers need to be reworked anyway, so this mild hack is acceptable for now.

[retry] Added configurable timeouts to retry timer

2008-08-12T00:05:26+00:00

New min_timeout and max_timeout fields in struct retry_timer allow users of this timer to set their own desired minimum and maximum timeouts, without being constrained to a single global minimum and maximum. Users of the timer can still elect to use the default global values by leaving the min_timeout and max_timeout fields as 0.

[dhcp] Work around a bug in Altiris RDP

2008-08-01T20:49:11+00:00

Altiris erroneously cares about the ordering of DHCP options, and will get confused if we don't construct them in the order it expects. This is observed (so far) only when attempting to deploy 64-bit Win2k3.

[dhcp] Verify DHCP server source port

2008-07-10T03:11:09+00:00

Verifying server ID and DHCP transaction ID is insufficient to differentiate between DHCPACK and ProxyDHCPACK when the DHCP server and Proxy DHCP server are the same machine.

[tftp] Strip the initial '/' to keep Windows TFTP servers happy.

[dhcp] Verify server identifier on ProxyDHCPACKs

2008-07-01T00:56:37+00:00

Perform the same test for a matching DHCP_SERVER_IDENTIFIER on ProxyDHCPACKs as we do for DHCPACKs. Otherwise, a retransmitted DHCPACK can end up being treated as the ProxyDHCPACK. I have a vague and unsettling memory that this test was deliberately omitted, but I can't remember why, and can't find anything in the VC logs.
