Which is to say you probably 25 shouldn't setjmp()/longjmp() between functions with EFIAPI (aka 26 __attribute__((ms_abi))) and those without. 27 28 Signed-off-by: Peter Jones <pjones (a] redhat.com> 29 Signed-off-by: Nigel Croxon <nigel.croxon (a] hp.com> 30 31 commit b5a8e93cec396381a6d2beee022abbf50100f2fd 32 Author: Nigel Croxon <nigel.croxon (a] hp.com> 33 Date: Fri Apr 10 08:49:50 2015 -0400 34 35 Bump version to 3.0.2 36 37 Signed-off-by: Nigel Croxon <nigel.croxon (a] hp.com> 38 39 commit 01c9f11ed5ad55661e8fc8a3eee35c578564754b 40 Author: Nigel Croxon <nigel.croxon (a] hp.com> 41 Date: Fri Apr 10 08:46:40 2015 -0400 42 43 Fix ARM32 and AARCH64 builds 44 Without these added into SUBDIRS the initplat.c compilation will fail. 45 46 Signed-off-by: Koen Kooi <koen.kooi (a] linaro.org> 47 Acked-by: Ard Biesheuvel <ard.biesheuvel (a] linaro.org> 48 Signed-off-by: Nigel Croxon <nigel.croxon (a] hp.com> 49 50 commit dada63fd3de148c6f8551d253355c113547cd5a0 51 Author: Nigel Croxon <nigel.croxon (a] hp.com> 52 Date: Mon Mar 23 10:41:43 2015 -0400 53 54 [PATCH] _SPrint: fix NULL termination 55 56 maxlen is the maximum string length not the buffer size. 57 58 Signed-off-by: Jeremy Compostella <jeremy.compostella (a] intel.com> 59 Signed-off-by: Nigel Croxon <nigel.croxon (a] hp.com> 60 61 commit ce7098fb52e5fd4d16038964d029eb759f28eaaf 62 Author: Nigel Croxon <nigel.croxon (a] hp.com> 63 Date: Thu Feb 19 11:22:45 2015 -0500 64 65 Enable out-of-tree building 66 67 This patch enables building gnu-efi outside of the source tree. 68 That in turn enables building for multiple architectures in parallel. 69 70 The build directory is controlled by the OBJDIR make variable.

That'll make a 133 file in the current directory gnu-efi-$VERSION.tar.bz2 , with its top 134 level directory gnu-efi-$VERSION/ and the source tree under that. 135 136 Once you've tested that and you're sure it's what you want to release, 137 you do "make archive", which will tag a release in git and generate a 138 final tarball from it. You then push to the archive, being sure to 139 include the tag: 140 141 git push origin master:master --tags 142 143 And upload the archive wherever it's supposed to go. 144 145 Signed-off-by: Peter Jones <pjones (a] redhat.com> 146 Signed-off-by: Nigel Croxon <nigel.croxon (a] hp.com> 147 148 commit 530d68ba191850edafc6da22cb2df55bec0c5fa5 149 Author: Nigel Croxon <nigel.croxon (a] hp.com> 150 Date: Tue Nov 25 10:09:50 2014 -0500 151 152 The gnu-efi-3.0 toplevel subdirectory is really annoying.

In this case everything happens to work fine even 505 if we forget uefi_call_wrapper(), because the wrapper would expand to 506 a normal C function call anyway. 507 508 (2) Otherwise (ie. gcc is old), EFIAPI expands to nothing, and we must 509 take into account the called function's origin: 510 511 (2a) If the callee that is declared EFIAPI is *defined* inside gnu-efi, 512 then EFIAPI means nothing for the callee too, so caller and callee 513 only understand each other if the caller intentionally omits 514 uefi_call_wrapper(). 515 516 (2b) If the callee that is declared EFIAPI is defined by the platform 517 UEFI implementation, then the caller *must* use 518 uefi_call_wrapper(). 519 520 The PRINT_STATE.Output EFIAPI function pointer is dereferenced correctly: 521 the PFLUSH() distinguishes cases (2a) from (2b) by using IsLocalPrint(). 522 523 However use of the PRINT_STATE.SetAttr EFIAPI function pointer is not 524 always correct: 525 526 - The PSETATTR() helper function always relies on the wrapper (case (2b)). 527 This is correct, because PRINT_STATE.SetAttr always points to a 528 platform-provided function. 529 530 - The DbgPrint() function contains two incorrect calls: they mistakenly 531 assume case (2a) (or case (1)), even though the pointer always points to 532 a platform function, implying (2b).

Parameters >=5 are copied to the stack and, when 876 passed small immediate values (and possibly other parameters), gcc 877 would emit a movl instruction before calling uefi_call_wrapper(). As a 878 result, only the lower 32b of these stack values are significant, the 879 upper 32b potentially contain garbage. Considering that 880 uefi_call_wrapper() assumes these arguments are clean 64b values 881 before calling the efi_callX() trampolines, the latter may be passed 882 garbage. This makes calling functions like 883 EFI_PCI_IO_PROTOCOL.Mem.Read()/Write() or BS->OpenProtocol() quite 884 unreliable. 885 886 This patch fixes this by turning uefi_call_wrapper() into a macro that 887 allows to expose the efi_callX() trampoline signatures to the callers, 888 so that gcc can know upfront that it has to pass all arguments to 889 efi_callX() as clean 64b values (eg. movq for immediates). The 890 _cast64_efi_callX macros are just here to avoid a gcc warning, they do 891 nothing otherwise. 892 893 Signed-off-by: David Decotigny <decot (a] googlers.com> 894 895 Author: noxorc <nigel.croxon (a] hp.com> 896 Date: Wed May 15 15:26:16 2013 -0400 897 898 - Removes the ElfW() macro usage from reloc_ia32.c and reloc_x86_64.c. These 899 macros only exist in link.h on Linux. On FreeBSD, the equivalent macro is 900 __ElfN(). But the macro usage is redundant. You're only going to compile the 901 ia32 file for IA32 binaries and the x86_64 file for X64 binaries. If you had 902 just one file built for both cases, then using the macro might make more 903 sense. 904 905 - Removes the "#define foo_t efi_foo_t" macros from reloc_ia32.c and 906 reloc_x86_64.c. 907 908 - Modifies inc/x86_64/efibind.h and inc/ia32/efibind.h to use the new 909 definitions for uint64_t, int64_t and int8_t. The 64-bit types are now defined 910 as: 911 912 typedef int __attribute__((__mode__(__DI__))) int64_t; 913 typedef unsigned int __attribute__((__mode__(__DI__))) uint64_t; 914 915 This removes the conflict between the host types dragged in by elf.h and the 916 type definitions in efibind.h that made the #define foo_t efi_foo_t" hack 917 necessary. Also, int8_t is now defined as signed char instead of just char 918 (assuming char == signed char is apparently not good enough). 919 920 - Also modifies these files to use stdint.h instead of stdint-gcc.h. It's 921 unclear if this is completely correct, but stdint-gcc.h is not present with 922 all GCC installs, and if you use -std=c99 or later you will force this case to 923 be hit. This also can break clang, which doesn't have a stdint-gcc.h at all. 924 925 - Removes the #include of <link.h> from reloc_ia32.c and reloc_x86_64.c (since 926 with the previous changes it's not needed anymore). 927 928 - Places the #include of <elf.h> after #include <efi>/#include <efilib.h> so 929 that we know the types will always be defined properly, in case you build on a 930 system where <elf.h> doesn't automatically pull in the right header files to 931 define all the needed types. (This actually happens on VxWorks. It's harmless 932 elsewhere. If you don't care about VxWorks, you can leave this out.) 933 934 - Modifies setjmp_ia32.S and setjmp_x86_64.S so to change "function" to 935 @function. The clang compiler doesn't like the former. Clang and GCC both like 936 the latter. 937 938 - Modifles Make.defaults so that if ARCH is detected as "amd64," it's changed 939 to "x86_64." It happens that uname -m on 64-bit FreeBSD reports the former 940 rather than the latter, which breaks the build. This may also be the case on 941 some other OSes. There's a way to force uname(1) to return x86_64 as the 942 machine type, but this way is a little friendlier. 943 944 - Creates gnuefi/elf_ia32_fbsd_efi.lds which specifies the object file type as 945 elf-ia32-freebsd. This is required for building on FreeBSD/i386, not just 946 FreeBSD/amd64. 947 948 - Modifies apps/Makefile to always use 949 $(TOPDIR)/gnuefi/elf_$(ARCH)_fbsd_efi.lds when building on either 32-bit or 950 64-bit FreeBSD instead of just for the x86_64 case. 951 952 - Changed LDFLAGS in Make.defaults to include --no-undefined. This will cause 953 linking to fail if there are any unsatisfied symbols when creating foo.so 954 during any of the app builds, as opposed to just silently succeeding and 955 producing an unusable binary. 956 957 - Changed CFLAGS to include -ffreestanding -fno-stack-protector -fno-stack- 958 check. This prevents clang from inserting a call to memset() when compiling 959 the RtZeroMem() and RtSetMem() routines in lib/runtime/efirtlib.c and guards 960 against the native compiler in some Linux distros from adding in stack 961 checking code which relies on libc help that isn't present in the EFI runtime 962 environment. 963 964 This does the following: 965 966 - Cleans up the ia32 and x86-64 relocation code a bit (tries to break the 967 dependency between the host ELF headers and the EFI runtime environment) 968 - Avoids the dependency on stdint-gcc.h which may not always be available 969 - Allows GNU EFI to build out of the box on both FreeBSD/i386 and 970 FreeBSD/amd64 971 - Allows GNU EFI to build out of the box with either GCC or clang on 972 FreeBSD/i386 and FreeBSD/amd64 9.0 and later. 973 - Makes things a little easier to port to VxWorks 974 - Avoids creating un-runable binaries with unresolved symbol definitions 975 (which can be very confusing to debug) 976 977 Author: noxorc <nigel.croxon (a] hp.com> 978 Date: Wed May 8 16:29:45 2013 -0400 979 980 Add the definitions for TCP, UDP and IP, for both IPv4 and IPv6. 981 982 983 2013-05-02 Nigel Croxon <nigel.croxon (a] hp.com> 984 * Chnage from Matt Fleming <matt.fleming (a] intel.com> 985 - Preparation for adding the networking protocol definitions. 986 Add the service binding protocol. 987 988 2013-02-21 Nigel Croxon <nigel.croxon (a] hp.com> 989 * Change from Peter Jones <pjones (a] redhat.com> 990 - Previously we were incorrectly passing 3 functions with 991 the System V ABI to UEFI functions as EFI ABI functions. 992 Mark them as EFIAPI so the compiler will (in our new 993 GNU_EFI_USE_MS_ABI world) use the correct ABI. 994 - These need to be EFIAPI functions because in some cases 995 they call ST->ConOut->OutputString(), which is an EFIAPI 996 function. (Which means that previously in cases that 997 needed "cdecl", these didn't work right.) 998 - If the compiler version is new enough, and GNU_EFI_USE_MS_ABI 999 is defined, use the function attribute ms_abi on everything 1000 defined with "EFIAPI". Such calls will no longer go through 1001 efi_call*, and as such will be properly type-checked. 1002 - Honor PREFIX and LIBDIR correctly when passed in during the build. 1003 - Add machine type defines for i386, arm/thumb, ia64, ebc, x86_64. 1004 - __STDC_VERSION__ never actually gets defined unless there's a 1005 --std=... line. So we were accidentally defining lots of c99 1006 types ourself. Since it's 2012, use --std=c11 where appropriate, 1007 and if it's defined and we're using gcc, actually include gcc's 1008 stdint definitions. 1009 - New test application added: route80h. This is a test program 1010 for PciIo. It routes ioport 80h on ICH10 to PCI. This is also 1011 useful on a very limited set of hardware to enable use of 1012 a port 80h debug card. 1013 - New test applcation added: modelist. This lists video modes 1014 the GOP driver is showing us. 1015 * Change from Finnbarr Murphy 1016 - https://sourceforge.net/p/gnu-efi/feature-requests/2/ 1017 Please add the following status codes to <efierr.h> 1018 EFI_INCOMPATIBLE_VERSION 25 1019 EFI_SECURITY_VIOLATION 26 1020 EFI_CRC_ERROR 27 1021 EFI_END_OF_MEDIA 28 1022 EFI_END_OF_FILE 31 1023 EFI_INVALID_LANGUAGE 32 1024 EFI_COMPROMISED_DATA 33 1025 * Change from SourceForge.net Bug report 1026 - https://sourceforge.net/p/gnu-efi/bugs/5/ 1027 BufferSize is a UINT64 *.

Return error status if relocation fails for some 1219 reason. 1220 1221 * gnuefi/elf_ia32_efi.lds: Drop unneeded ".rel.reloc" section. 1222 1223 * gnuefi/crt0-efi-ia32.S (_start): Exit if _relocate() returns with 1224 non-zero exit status. 1225 1226 * inc/ia32/efibind.h [__GNUC__]: Force 8-byte alignment for 64-bit 1227 types as that is what EFI appears to be expecting, despite the 1228 "#pragma pack()" at the beginning of the file! 1229 1230 2001-03-29 David Mosberger <davidm (a] hpl.hp.com> 1231 1232 * gnuefi/reloc_ia32.c: Add a couple of defines to work around 1233 libc/efilib collision on uint64_t et al. 1234 (_relocate): Use ELF32_R_TYPE() instead of ELFW(R_TYPE)(). 1235 1236 * gnuefi/crt0-efi-ia32.S (dummy): Add a dummy relocation entry. 1237 1238 2001-03-29 David Mosberger <davidm (a] hpl.hp.com> 1239 1240 * gnuefi/reloc_ia32.c: Add a couple of defines to work around 1241 libc/efilib collision on uint64_t et al. 1242 (_relocate): Use ELF32_R_TYPE() instead of ELFW(R_TYPE)(). 1243 1244 * gnuefi/crt0-efi-ia32.S (dummy): Add a dummy relocation entry. 1245 1246 2000-10-26 David Mosberger <davidm (a] hpl.hp.com> 1247 1248 * gnuefi/elf_ia64_efi.lds: Mention .rela.sdata. 1249 1250 * Make.defaults (CFLAGS): Remove -nostdinc flags so we can pick 1251 up the C compiler's stdarg.h. 1252 1253 * inc/stdarg.h: Remove this file. It's not correct for gcc (nor 1254 most other optimizing compilers). 1255 1256 2000-10-10 Stephane Eranian <eranian (a] hpl.hp.com> 1257 1258 * cleaned up the error message and printing of those. 1259 * added support to load the FPSWA from a file in case support is not 1260 present in the firmware already 1261 * fixed split_args() to do the right thing when you have leading spaces 1262 before kernel name 1263 * changed the argify() function to rely on \0 instead of LoadOptionSize 1264 as the field seems to be broken with current firmware 1265 * bumped version to 1.0 1266 1267 2000-10-04 David Mosberger <davidm (a] hpl.hp.com> 1268 1269 * gnuefi/reloc_ia64.S: Reserve space for up to 750 function descriptors. 1270 1271 * gnuefi/elf_ia64_efi.lds: Add .sdata section for small data and 1272 put __gp in the "middle" of it. 1273 1274 * gnuefi/crt0-efi-ia64.S (_start): Use movl/add to load 1275 gp-relative addresses that could be out of the range of the addl 1276 offset. 1277 * gnuefi/reloc_ia64.S (_relocate): Ditto. 1278 1279 * apps/Makefile: Remove standard rules and include Make.rules instead. 1280 * lilo/Makefile: Ditto. 1281 1282 * Make.rules: New file. 1283 1284 2000-08-04 Stephane Eranian <eranian (a] hpl.hp.com> 1285 * released version 0.9 1286 * incorporated ACPI changes for Asuza by NEC < kouchi (a] hpc.bs1.fc.nec.co.jp> 1287 * added support for initrd (-i option) original ELI code from Bill Nottingham <notting (a] redhat.com>) 1288 * lots of cleanups 1289 * got rid of #ifdef LILO_DEBUG and uses macro instead 1290 * fix a few extra memory leaks in create_boot_params() 1291 * added exit capability just before starting the kernel 1292 1293 2000-06-22 David Mosberger <davidm (a] hpl.hp.com> 1294 1295 * gnuefi/elf_ia64_efi.lds: Add .srodata, .ctors, .IA64.unwind, 1296 .IA64.unwind_info to .data section and .rela.ctors to .rela 1297 section. 1298 1299 2000-04-03 David Mosberger <davidm (a] hpl.hp.com> 1300 1301 * lilo/lilo.c (LILO_VERSION): Up version number to 0.9. 1302 1303 * gnuefi/elf_ia64_efi.lds: Include .IA_64.unwind and 1304 .IA_64.unwind_info in .data segment to avoid EFI load error 1305 "ImageAddress: pointer outside of image" error due to the .dynsym 1306 relocations against these sections. 1307 1308 * ChangeLog: Moved from lilo/ChangeLogs. 1309 1310 * gnuefi/reloc_ia64.S: fixed typo: .space directive had constant 1311 100 hardcoded instead of using MAX_FUNCTION_DESCRIPTORS 1312 macro. Duh. 1313 1314 2000-03-17 Stephane Eranian <eranian (a] hpl.hp.com> 1315 1316 * Released 0.8 1317 * replace the getopt.c with new version free with better license 1318 * created a documentation file 1319 * fix a couple of memory leaks 1320 * code cleanups 1321 * created a separate directory for lilo in the gnu-efi package. 1322 * added support for the BOOT_IMAGE argument to kernel 1323 * default is to build natively now 1324 1325
