* [build] Mark core files as permitted for UEFI Secure BootMichael Brown2026-01-141-0/+1
| | | | | | | | | | | | Mark all files used in a standard build of bin-x86_64-efi/snponly.efi as permitted for UEFI Secure Boot. These files represent the core functionality of iPXE that is guaranteed to have been included in every binary that was previously subject to a security review and signed by Microsoft. It is therefore legitimate to assume that at least these files have already been reviewed to the required standard multiple times. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [smbios] Remove userptr_t from SMBIOS structure parsingMichael Brown2025-04-231-132/+117Star
| | | | | | | | | | | | | Simplify the SMBIOS structure parsing code by assuming that all structure content is fully accessible via pointer dereferences. In particular, this allows the convoluted find_smbios_structure() and read_smbios_structure() to be combined into a single function smbios_structure() that just returns a direct pointer to the SMBIOS structure, with smbios_string() similarly now returning a direct pointer to the relevant string.

* [uaccess] Remove user_to_phys() and phys_to_user()Michael Brown2025-04-211-4/+4
| | | | | | | | Remove the intermediate concept of a user pointer from physical address conversions, leaving virt_to_phys() and phys_to_virt() as the directly implemented functions. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [uaccess] Remove redundant memcpy_user() and related string functionsMichael Brown2025-04-211-1/+1
| | | | | | | | | | The memcpy_user(), memmove_user(), memcmp_user(), memset_user(), and strlen_user() functions are now just straightforward wrappers around the corresponding standard library functions. Remove these redundant wrappers. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [smbios] Support scanning for the 64-bit SMBIOS3 entry pointMichael Brown2023-12-291-13/+65
| | | | | | | | | | Support scanning for the 64-bit SMBIOS3 entry point in addition to the 32-bit SMBIOS2 entry point. Prefer use of the 32-bit entry point if present, since this is guaranteed to be within accessible memory. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [smbios] Add support for the 64-bit SMBIOS3 entry pointMichael Brown2020-12-291-2/+7
| | | | | | | Support UEFI systems that provide only 64-bit versions of the SMBIOS entry point. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [legal] Relicense files under GPL2_OR_LATER_OR_UBDLMichael Brown2015-03-021-1/+5

* [smbios] Allow access to multiple instances of SMBIOS structuresMichael Brown2013-05-011-2/+4
| | | | | | | | | | | | | | | | | | | | | | | Extend the syntax for numerical SMBIOS settings from smbios/<type>.<offset>.<length> to smbios/[<instance>.]<type>.<offset>.<length> Where SMBIOS provides multiple structures with the same <type>, this extended syntax allows for access to structures other than the first. If <instance> is omitted then it will default to zero, giving access to the first instance (and so matching existing behaviour). The 16-bit SMBIOS handle (which is an alternative way to disambiguate multiple instances of the same type of structure) can be accessed, if required, using smbios/<instance>.<type>.2.2:uint16 Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [build] Rename gPXE to iPXEMichael Brown2010-04-201-2/+2
| | | | | | | | | | | 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.

* [legal] Add a selection of FILE_LICENCE declarationsMichael Brown2009-05-181-0/+2
| | | | | Add FILE_LICENCE declarations to almost all files that make up the various standard builds of gPXE.
* [efi] Use EFI-native mechanism for accessing SMBIOS tableMichael Brown2008-12-051-0/+178
EFI provides a copy of the SMBIOS table accessible via the EFI system table, which we should use instead of manually scanning through the F000:0000 segment.
