Author: kevans Date: Mon Feb 12 20:51:28 2018 New Revision: 329183 URL: https://svnweb.freebsd.org/changeset/base/329183 Log: MFC Loader Fixes Final: r327612,r327703,r327704,r327878,r327879,r327881, r328007,r328029,r328030,r328031,r328061,r328156,r328169,r328288,r328289, r328290,r328291,r328292,r328411,r328536,r328603,r328614,r328642,r328769, r328779,r328780,r328781,r328782,r328783,r328806,r328808,r328826,r328835, r328911,r328986,r328987,r328990,r328999,r329000,r329019,r329050,r329054, r329060 r327612: Invent new #defines for the biospci_{read,write}_config function r327703: Define __dmadat after #include'ing ufsread.c. r327704: Fix printf missing format variables warnings. r327878: Add GUID for UEFI boot manager variables. r327879: Report the boot order and where we are in that boot order. r327881: Allow this file to be included r328007: Fix booting on some arm64 systems after r327879 by fixing the call to utf8_to_ucs2 r328029: When returning an error and freeing allocated memory from ucs2_to_utf8, NULL the return pointer. r328030: Check the return value from utf8_to_ucs2 instead of whether or not uv is NULL. r328031: Need to free uv after we're done using it. r328061: utf8_to_ucs2() should check for malloc failure r328156: stand: Move sections around to fix stand/ build with ld.lld on armv7 r328169: Remove extra copy of bootinfo.c. It's a bit rotted copy of the one in efi/loader. r328288: Fix some resource leaks. r328289: Don't leak memory when displaying help. r328290: On malloc failure, be sure to close the include file that triggered it. r328291: getenv does not return tainted data in the boot loader. Attempt to clue Coverity into that fact. r328292: There's no tainted data here, tag it as such to avoid false positives. r328411: loader.efi: add missing EFI GUIDs r328536: loader: support for mixed-endianness ELF/loader and POWER8 r328603: Add missing non-POWERPC case to give the scr value something non-zero. r328614: Move libstand.3 to libsa.3. Update libsa.3 to include functions r328642: Break out the interpreters (simple and forth) w/o ifdefs. r328769: Centralize several variables. r328779: Retire pnp.4th and the code needed only for 4th words used here. r328780: These 4th words were an attempt to allow integration into the boot loader scripts. However, that path won't be taken after all it seems. r328781: Remove pcibios forth support. r328782: Now that we no longer conditionally compile some files outside of ficl r328783: Invent new LDR_INTERP for the loader interpreter to use. r328806: We need more heap space to properly load newer powerpc kernels. r328808: Implement strcoll as strcmp. r328826: Make cross-endian loader changes apply only to powerpc r328835: Fix regression introduced in r328806, preventing boot on many platforms. r328911: Ignore relocation tables for non-memory-resident sections. r328986: Fix relative location of USB sources after recent move. r328987: A more definitions to kernel emulation shim in order to build stand/usb. r328990: Move the stand/usb test loader into its own directory. r328999: Fix indentation to FreeBSD standard for interp files r329000: Move simple interpreter 'perform' into interp.c and call it r329019: Move to tabs for indentation and to 8-space notches, per style(9). r329050: Fix build of userboot.so r329054: Set script.lang in the environment to either 'forth' or 'simple' to reflect what scripting language was compiled into the loader. r329060: loader: fix
