More va_* work

2021-03-12T09:15:01+00:00

Be much more explicit about exactly which va_* stuff comes from which ABI in both shim and gnu-efi. This fixes the problem where we see: | (null):0:(null)() v->name:"(null)" v->rtname:"(null)" | (null):0:(null)() v->data_size:0 v->data:0x0 and similar messages where everything is NULL.

Add some test cases, and make "make test" actually work.

Note the one test case I'm not 100% sure about. Someone let me know. Signed-off-by: Peter Jones

Fix stdarg to work the same everywhere.

2021-03-10T20:54:20+00:00

This gets us the same working definition for VA_* va_* etc everywhere, and it's the same definition edk2 is using. Signed-off-by: Peter Jones

Restructure our includes.

2021-03-10T20:54:20+00:00

This re-structures our includes so we can be sure everything is always including all the system headers in a uniform, predictable way. Temporarily it also adds a bunch of junk at all the places we use variadic functions to specifically pick either the MS (cdecl) or ELF ABIs. I'm not 100% sure that's all correct (see later patch) but it's enough to allow this to build. Signed-off-by: Peter Jones

Restore loaded image of shim at Exit()

2021-03-07T00:02:58+00:00

When grub2 invoked Exit() in AArch64 AAVMF, the VM crashed with the following messsages: Unloading driver at 0x000B7D7B000 Synchronous Exception at 0x00000000BF5D5E68 AllocatePool: failed to allocate 800 bytes Synchronous Exception at 0x00000000BF5D5E68 The similar error also showed when I modified MokManager to call gBS->Exit() at the end of efi_main(). However, if MokManager just returned, the error never showed. One significant difference is whether the loaded image was restored or not, and the firmware seems to need the original ImageBase pointer to do clean-up. To avoid the potential crash, this commit adds restore_loaded_image() so that we can restore the loaded image both in start_image() and do_exit(). Signed-off-by: Gary Lin

make 'make test' able to run unit test harnesses

2021-02-25T15:15:14+00:00

This adds a couple of make targets to do unit tests that are linked to libc: test-FOO : builds and runs test-FOO for any test-FOO.c test : builds and runs all test-FOO tests Note that building and running this test does not quite work yet /on this branch/. In order to do that, we need some cleanups and reorganizing that I don't want to push just yet, which can be found on https://github.com/rhboot/shim/tree/test-reorg Signed-off-by: Peter Jones

Fix our debuginfo paths hopefully

2021-02-25T15:15:14+00:00

includes: include all gnu-efi includes at one place.

compiler.h: fix a typo and add some more function attribute macros

2021-02-25T15:15:14+00:00

This fixes the ifndef guard on NONNULL and __CONCAT3 and adds definitions for: - __CONCAT() for a##b with the intermediate tokenization step - ALLOCFUNC for __malloc__ - DEPRECATED for __deprecated__ - PURE for __pure__ - RETURNS_NONNULL for __nonnull__ Signed-off-by: Peter Jones
