* [ipv6] Rename ipv6_scope to dhcpv6_scopeMichael Brown2016-07-161-1/+1
| | | | | | | | The settings scope ipv6_scope refers specifically to IPv6 settings that have a corresponding DHCPv6 option. Rename to dhcpv6_scope to more accurately reflect this purpose. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [legal] Relicense files under GPL2_OR_LATER_OR_UBDLMichael Brown2015-03-021-1/+5
| | | | | | | | | | These files cannot be automatically relicensed by util/relicense.pl since they either contain unusual but trivial contributions (such as the addition of __nonnull function attributes), or contain lines dating back to the initial git revision (and so require manual knowledge of the code's origin).

* [dns] Update end-of-name pointer after processing CNAME recordMichael Brown2014-02-261-2/+12
| | | | | | | | | | | | | | | | | | | | | Commit d4c0226 ("[dns] Support DNS search lists") introduced a regression when handling CNAME records resolving to names longer than the original name. The "end of name" offset stored in dns->offset was not updated to reflect the length of the new name, causing dns_question() to append the (empty) search suffix at an incorrect offset within the name buffer, resulting in a mangled DNS name. In the case of a CNAME record resolving to a name shorter than or equal in length to the original name, then the mangling would occur in an unused portion of the name buffer. In the common case of a name server returning the A (or AAAA) record along with the CNAME record, this would cause name resolution to succeed despite the mangling. (If the name server did not return the A or AAAA record along with the CNAME record, then the mangling would be revealed by the subsequent invalid query packet.)

* [dns] Support DNS search listsMichael Brown2014-02-051-265/+703
| | | | | | | | | | | Update the DNS resolver to support DNS search lists (as provided by DHCP option 119, DHCPv6 option 24, or NDP option 31). Add validation code to ensure that parsing of DNS packets does not overrun the input, get stuck in infinite loops, or (worse) write beyond the end of allocated buffers.

* [settings] Merge SETTING_IPv4 and SETTING_IPv6Michael Brown2013-12-051-2/+2
| | | | | | | Allow for equivalent IPv4 and IPv6 settings (which requires equivalent settings to be adjacent within the settings list). Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [dns] Add support for resolving IPv6 addresses via AAAA recordsMichael Brown2013-12-051-33/+102
| | | | | | | | Our policy is to prefer IPv6 addreses to IPv4 addresses, but to request IPv6 addresses only if we have an IPv6 address for the name server itself. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [settings] Explicitly separate the concept of a completed fetched settingMichael Brown2013-12-051-6/+2Star
| | | | | | | | | | The fetch_setting() family of functions may currently modify the definition of the specified setting (e.g. to add missing type information). Clean up this interface by requiring callers to provide an explicit buffer to contain the completed definition of the fetched setting, if required. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [retry] Hold reference while timer is running and during expiry callbackMichael Brown2010-09-031-1/+1
| | | | | | | | | Guarantee that a retry timer cannot go out of scope while the timer is running, and provide a guarantee to the expiry callback that the timer will remain in scope during the entire callback (similar to the guarantee provided to interface methods).

* [interface] Convert all data-xfer interfaces to generic interfacesMichael Brown2010-06-221-36/+45
| | | | | | | | | | | | | | Remove data-xfer as an interface type, and replace data-xfer interfaces with generic interfaces supporting the data-xfer methods. Filter interfaces (as used by the TLS layer) are handled using the generic pass-through interface capability. A side-effect of this is that deliver_raw() no longer exists as a data-xfer method. (In practice this doesn't lose any efficiency, since there are no instances within the current codebase where xfer_deliver_raw() is used to pass data to an interface supporting the deliver_raw() method.)

* [build] Rename gPXE to iPXEMichael Brown2010-04-201-9/+9
| | | | | | | | | | | Access to the gpxe.org and etherboot.org domains and associated resources has been revoked by the registrant of the domain. Work around this problem by renaming project from gPXE to iPXE, and updating URLs to match. Also update README, LOG and COPYRIGHTS to remove obsolete information.

| | | | | When handling a redirection event, we need to close the existing connection before opening the new connection.
* [dns] Append local domain to relative namesStefan Hajnoczi2009-01-271-11/+65
| | | | | | | | | | | | | | | Try to qualify relative names in the DNS resolver using the DHCP Domain Name. For example: DHCP Domain Name: etherboot.org (Relative) Name: www yields: www.etherboot.org Only names with no dots ('.') will be modified. A name with one or more dots is unchanged.
* [Settings] Remove assumption that all settings have DHCP tag valuesMichael Brown2008-03-251-1/+16
| | | | | | | | | | | | Allow for settings to be described by something other than a DHCP option tag if desirable. Currently used only for the MAC address setting. Separate out fake DHCP packet creation code from dhcp.c to fakedhcp.c. Remove notion of settings from dhcppkt.c. Rationalise dhcp.c to use settings API only for final registration of the DHCP options, rather than using {store,fetch}_setting throughout.
