All of these are derived from the Tiano code, but I re-wrote the x86_64 one because we use the ELF psABI calling conventions instead of the MS ABI calling conventions. Which is to say you probably shouldn't setjmp()/longjmp() between functions with EFIAPI (aka __attribute__((ms_abi))) and those without.

That in turn enables building for multiple architectures in parallel. The build directory is controlled by the OBJDIR make variable. It defaults to the value of ARCH, and can be overridden from the command line. This patch also cleans up some doubled slashes between INSTALLROOT and PREFIX.

That'll make a file in the current directory gnu-efi-$VERSION.tar.bz2 , with its top level directory gnu-efi-$VERSION/ and the source tree under that. Once you've tested that and you're sure it's what you want to release, you do "make archive", which will tag a release in git and generate a final tarball from it. You then push to the archive, being sure to include the tag: git push origin master:master --tags And upload the archive wherever it's supposed to go.

In this case everything happens to work fine even if we forget uefi_call_wrapper(), because the wrapper would expand to a normal C function call anyway. (2) Otherwise (ie. gcc is old), EFIAPI expands to nothing, and we must take into account the called function's origin: (2a) If the callee that is declared EFIAPI is *defined* inside gnu-efi, then EFIAPI means nothing for the callee too, so caller and callee only understand each other if the caller intentionally omits uefi_call_wrapper(). (2b) If the callee that is declared EFIAPI is defined by the platform UEFI implementation, then the caller *must* use uefi_call_wrapper(). The PRINT_STATE.Output EFIAPI function pointer is dereferenced correctly: the PFLUSH() distinguishes cases (2a) from (2b) by using IsLocalPrint(). However use of the PRINT_STATE.SetAttr EFIAPI function pointer is not always correct: - The PSETATTR() helper function always relies on the wrapper (case (2b)). This is correct, because PRINT_STATE.SetAttr always points to a platform-provided function. - The DbgPrint() function contains two incorrect calls: they mistakenly assume case (2a) (or case (1)), even though the pointer always points to a platform function, implying (2b). (The error is masked in case (1).) Fix them.

Signed-off-by: Nigel Croxon 2013-10-07 Nigel Croxon if you have a function that takes const arguments and then e.g. tries to copy StrCmp, gcc will give you warnings about those calls, and the warnings are right. These clutter up other things you might miss that you should be more concered about. You could work around it through vigorous typecasting to non-const types, but why should you have to? All of these functions are regorously defined as not changing their input - it is const, and should be marked as such.

This will be even more annoying, since most UEFI firmwares don't initialize the #DE or #UD trap handlers, and your backtrace will be a random path through uninitialized memory, occasionally including whatever address the IDT has for #UD, but also addresses like "0x4" and "0x507" that you don't normally expect to see in your call path.

Signed-off-by: David Decotigny Author: Nigel Croxon Date: Wed Jun 12 09:38:10 2013 -0400 fix parameter-passing corruption on x86_64 for >= 5 args On x86_64 without HAVE_USE_MS_ABI support, uefi_call_wrapper() is a variadic function. Parameters >=5 are copied to the stack and, when passed small immediate values (and possibly other parameters), gcc would emit a movl instruction before calling uefi_call_wrapper(). As a result, only the lower 32b of these stack values are significant, the upper 32b potentially contain garbage. Considering that uefi_call_wrapper() assumes these arguments are clean 64b values before calling the efi_callX() trampolines, the latter may be passed garbage. This makes calling functions like EFI_PCI_IO_PROTOCOL.Mem.Read()/Write() or BS->OpenProtocol() quite unreliable. This patch fixes this by turning uefi_call_wrapper() into a macro that allows to expose the efi_callX() trampoline signatures to the callers, so that gcc can know upfront that it has to pass all arguments to efi_callX() as clean 64b values (eg. movq for immediates). The _cast64_efi_callX macros are just here to avoid a gcc warning, they do nothing otherwise. Signed-off-by: David Decotigny Author: noxorc Date: Wed May 15 15:26:16 2013 -0400 - Removes the ElfW() macro usage from reloc_ia32.c and reloc_x86_64.c. These macros only exist in link.h on Linux. On FreeBSD, the equivalent macro is __ElfN(). But the macro usage is redundant. You're only going to compile the ia32 file for IA32 binaries and the x86_64 file for X64 binaries. If you had just one file built for both cases, then using the macro might make more sense. - Removes the "#define foo_t efi_foo_t" macros from reloc_ia32.c and reloc_x86_64.c. - Modifies inc/x86_64/efibind.h and inc/ia32/efibind.h to use the new definitions for uint64_t, int64_t and int8_t. The 64-bit types are now defined as: typedef int __attribute__((__mode__(__DI__))) int64_t; typedef unsigned int __attribute__((__mode__(__DI__))) uint64_t; This removes the conflict between the host types dragged in by elf.h and the type definitions in efibind.h that made the #define foo_t efi_foo_t" hack necessary. Also, int8_t is now defined as signed char instead of just char (assuming char == signed char is apparently not good enough). - Also modifies these files to use stdint.h instead of stdint-gcc.h. It's unclear if this is completely correct, but stdint-gcc.h is not present with all GCC installs, and if you use -std=c99 or later you will force this case to be hit. This also can break clang, which doesn't have a stdint-gcc.h at all. - Removes the #include of from reloc_ia32.c and reloc_x86_64.c (since with the previous changes it's not needed anymore). - Places the #include of after #include /#include so that we know the types will always be defined properly, in case you build on a system where doesn't automatically pull in the right header files to define all the needed types. (This actually happens on VxWorks. It's harmless elsewhere. If you don't care about VxWorks, you can leave this out.) - Modifies setjmp_ia32.S and setjmp_x86_64.S so to change "function" to @function. The clang compiler doesn't like the former. Clang and GCC both like the latter. - Modifles Make.defaults so that if ARCH is detected as "amd64," it's changed to "x86_64." It happens that uname -m on 64-bit FreeBSD reports the former rather than the latter, which breaks the build. This may also be the case on some other OSes. There's a way to force uname(1) to return x86_64 as the machine type, but this way is a little friendlier. - Creates gnuefi/elf_ia32_fbsd_efi.lds which specifies the object file type as elf-ia32-freebsd. This is required for building on FreeBSD/i386, not just FreeBSD/amd64. - Modifies apps/Makefile to always use $(TOPDIR)/gnuefi/elf_$(ARCH)_fbsd_efi.lds when building on either 32-bit or 64-bit FreeBSD instead of just for the x86_64 case. - Changed LDFLAGS in Make.defaults to include --no-undefined. This will cause linking to fail if there are any unsatisfied symbols when creating foo.so during any of the app builds, as opposed to just silently succeeding and producing an unusable binary. - Changed CFLAGS to include -ffreestanding -fno-stack-protector -fno-stack- check. This prevents clang from inserting a call to memset() when compiling the RtZeroMem() and RtSetMem() routines in lib/runtime/efirtlib.c and guards against the native compiler in some Linux distros from adding in stack checking code which relies on libc help that isn't present in the EFI runtime environment. This does the following: - Cleans up the ia32 and x86-64 relocation code a bit (tries to break the dependency between the host ELF headers and the EFI runtime environment) - Avoids the dependency on stdint-gcc.h which may not always be available - Allows GNU EFI to build out of the box on both FreeBSD/i386 and FreeBSD/amd64 - Allows GNU EFI to build out of the box with either GCC or clang on FreeBSD/i386 and FreeBSD/amd64 9.0 and later. - Makes things a little easier to port to VxWorks - Avoids creating un-runable binaries with unresolved symbol definitions (which can be very confusing to debug) Author: noxorc Date: Wed May 8 16:29:45 2013 -0400 Add the definitions for TCP, UDP and IP, for both IPv4 and IPv6. 2013-05-02 Nigel Croxon * Chnage from Matt Fleming - Preparation for adding the networking protocol definitions. Add the service binding protocol. 2013-02-21 Nigel Croxon * Change from Peter Jones - Previously we were incorrectly passing 3 functions with the System V ABI to UEFI functions as EFI ABI functions. Mark them as EFIAPI so the compiler will (in our new GNU_EFI_USE_MS_ABI world) use the correct ABI. - These need to be EFIAPI functions because in some cases they call ST->ConOut->OutputString(), which is an EFIAPI function. (Which means that previously in cases that needed "cdecl", these didn't work right.) - If the compiler version is new enough, and GNU_EFI_USE_MS_ABI is defined, use the function attribute ms_abi on everything defined with "EFIAPI". Such calls will no longer go through efi_call*, and as such will be properly type-checked. - Honor PREFIX and LIBDIR correctly when passed in during the build. - Add machine type defines for i386, arm/thumb, ia64, ebc, x86_64. - __STDC_VERSION__ never actually gets defined unless there's a --std=... line. So we were accidentally defining lots of c99 types ourself. Since it's 2012, use --std=c11 where appropriate, and if it's defined and we're using gcc, actually include gcc's stdint definitions. - New test application added: route80h. This is a test program for PciIo. It routes ioport 80h on ICH10 to PCI. This is also useful on a very limited set of hardware to enable use of a port 80h debug card. - New test applcation added: modelist. This lists video modes the GOP driver is showing us. * Change from Finnbarr Murphy - https://sourceforge.net/p/gnu-efi/feature-requests/2/ Please add the following status codes to EFI_INCOMPATIBLE_VERSION 25 EFI_SECURITY_VIOLATION 26 EFI_CRC_ERROR 27 EFI_END_OF_MEDIA 28 EFI_END_OF_FILE 31 EFI_INVALID_LANGUAGE 32 EFI_COMPROMISED_DATA 33 * Change from SourceForge.net Bug report - https://sourceforge.net/p/gnu-efi/bugs/5/ BufferSize is a UINT64 *.

Multiple people have complained that gummiboot hangs right away, which is in part the fault of gummiboot, but happens only because the stack gets screwed. x86_64 EFI already aligns the stack, so there's no need for so much code to find a proper alignment, we always need to shift by 8 anyway. * Change from A.
