Fork of ipxe; additional commands and features https://git.openslx.org/openslx-ng/ipxe.git/atom/src/interface/pxe/pxe_preboot.c?h=v0.9.4 2008-07-17T16:45:17+00:00 2008-07-17T16:45:17+00:00 Michael Brown 2008-07-17T16:45:17+00:00 urn:sha1:03c80c12b8e9019554c3bd4545cf68926ee1ce47 Add yet another ugly hack to iscsiboot.c, this time to allow the user to inhibit the shutdown/removal of the iSCSI INT13 device (and the network devices, since they are required for the iSCSI device to function). On the plus side, the fact that shutdown() now takes flags to differentiate between shutdown-for-exit and shutdown-for-boot means that another ugly hack (to allow returning via the PXE stack on BIOSes that have broken INT 18 calls) will be easier. I feel dirty. 2008-07-01T01:52:13+00:00 Michael Brown 2008-07-01T01:52:13+00:00 urn:sha1:4fbbf651d7cb91983801904f5ed2b07d15566c1d __from_data16 and __from_text16 now take a pointer to a .data16/.text16 variable, and return the real-mode offset within the appropriate segment. This matches the use case for every occurrence of these macros, and prevents potential future bugs such as that fixed in commit d51d80f. (The bug arose essentially because "&pointer" is still syntactically valid.) 2008-07-01T01:35:51+00:00 Michael Brown 2008-07-01T01:35:51+00:00 urn:sha1:d51d80f7854be874c7f60c6fda40d073cdfe717d __from_data16 takes the value pointed to, rather than the pointer itself. This was silently causing gPXE to return a dud buffer pointer when the caller did not supply a buffer for PXENV_GET_CACHED_INFO. 2008-03-25T20:46:16+00:00 Michael Brown 2008-03-25T20:46:16+00:00 urn:sha1:92d15eff30410dcb0ec406e06b131fb7d9179ffd 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. 2008-03-23T21:58:05+00:00 Michael Brown 2008-03-23T21:58:05+00:00 urn:sha1:ee4206a8a76c6d73c014f2261d4e7a1e093a40a8 Add dedicated functions create_dhcpdiscover(), create_dhcpack() and create_proxydhcpack() for use by external code such as the PXE preboot code. Register ProxyDHCP options under the global scope "proxydhcp". Unregister previously-acquired DHCP and ProxyDHCP settings when DHCP succeeds. 2008-03-21T22:15:31+00:00 Michael Brown 2008-03-21T22:15:31+00:00 urn:sha1:8afb36c3bc08ff0c9bdf0a8496cb08a8bfe287f3 2008-03-10T11:46:55+00:00 Michael Brown 2008-03-10T11:46:55+00:00 urn:sha1:1dd3f889641ca2ca997e6c1a734fbf39033c2730 WinPE's pxeboot.n12 takes the BufferLimit returned by gPXE (indicating the size of gPXE's internal DHCP packet buffers) and erroneously passes it in as BufferSize (indicating the size of pxeboot.n12's DHCP packet buffer). If these don't match, then pxeboot.n12 ends up instructing gPXE to overwrite parts of its data segment. Change gPXE's internal DHCP packet buffers to be exactly sizeof(BOOTPLAYER_t) bytes to work around this problem. 2008-01-22T18:51:12+00:00 Michael Brown 2008-01-22T18:51:12+00:00 urn:sha1:c9c8cdeb8b3c914b68b48b611640e70ec9f47c80 stored DHCP packets. 2007-12-07T01:06:37+00:00 Michael Brown 2007-12-07T01:06:37+00:00 urn:sha1:6b0e147e0de3c3f2747d200a20e9a1327fac0cf4 PXENV_GET_CACHED_INFO. NTLDR does this. 2007-11-22T04:43:11+00:00 Michael Brown 2007-11-22T04:43:11+00:00 urn:sha1:838ecba1315a484f8e08f41a3537623dfd7f1966 PXENV_GET_CACHED_INFO. If we dont do this, Altiris' NBP screws up; it relies on being able to grab pointers to each of the three packets and then read them at will later.
