2015-05-12Fix build with GCC 5, forcing -std=gnu89 to not rely on stdint.hMathieu Trudel-Lapierre
required by efibind.h, and not found with -nostdinc. (LP: #1429978)
2015-05-12Make the build failed with objcopy < 2.24Gary Ching-Pang Lin
The wildcard support was introduced in objcopy since binutils 2.24. However, objcopy < 2.24 never issues any warning message with the wildcard and a faulty binary will be generated. This commit makes the build failed as a notification for the usage of binutils < 2.24. Signed-off-by: Gary Ching-Pang Lin <glin@suse.com>

2015-04-15Explicitly request sysv-style ELF hash sectionsMatthew Garrett
We depend on there being a .hash section in the binary, and that's not the case on distributions that default to building with gnu-style ELF hashes. Explicitly request sysv-style hashes in order to avoid building broken binaries. Signed-off-by: Matthew Garrett <mjg59@coreos.com>

2015-04-13Fix length of allocated buffer for boot option comparison.Laszlo Ersek
The following commit: commit 4aac8a1179e160397d7ef8f1e3232cfb4f3373d6 Author: Gary Ching-Pang Lin <glin@suse.com> Date: Thu Mar 6 10:57:02 2014 +0800 [fallback] Fix the data size for boot option comparison corrected the data size used for comparison, but also reduced the allocation so it doesn't include the trailing UTF16LE '\0\0' at the end of the string, with the result that the trailer of the buffer containing the string is overwritten, which OVMF detects as memory corruption. Increase the size of the storage buffer in a few places to correct this problem. Signed-off-by: Richard W.M.

2015-04-13Don't install our protocols if we're not in secure mode.Peter Jones
System services haven't been hooked if we're not in secure mode, so do_exit() will never be called. In this case shim never gets control once grub exits, which means if booting fails and the firmware tries another boot option, it'll attempt to talk to the shim protocol we installed. This is wrong, because it is allowed to have been cleared from ram at this time, since the task it's under has exited. So just don't install the protocols when we're not enforcing. This version also has a message and a 2-second stall after calling start_image(), so that we can tell if we are on the expected return path of our execution flow.
2015-04-13Align the sections we're loading, and check for validity /after/ discarding.Peter Jones
Turns out a) the codegen on aarch64 generates code that has real alignment needs, and b) if we check the length of discardable sections before discarding them, we error for no reason. So do the error checking in the right order, and always enforce some alignment because we know we have to. Signed-off-by: Peter Jones <pjones@redhat.com>

2014-10-02Correctly reject bad tftp addresses earlier, rather than later.Peter Jones
This check is for end == NULL but was meant to be *end == '\0'. Without this change, we'll pass a plausibly bad address (i.e. one with no ']' at the end) to Mtftp(... READ_FILE ...), which should fail correctly, but our error messaging will be inconsistent. Signed-off-by: Peter Jones <pjones@redhat.com>

2014-09-30Actually find the relocations correctly and process them that way.Peter Jones
Find the relocations based on the *file* address in the old binary, because it's only the same as the virtual address some of the time. Also perform some extra validation before processing it, and don't bail out in /error/ if both ReloceBase and RelocEnd are null - that condition is fine.

2014-09-21Do the same for ia32...Peter Jones
Once again, on ia32 this time, we see: 00000120 47 84 00 00 0a 00 00 00 00 00 00 00 00 00 00 00 |G...............| Which is where the pointer on ia32 for the Base Relocation Table should be. It points to 0x8447, which isn't a particularly reasonable address as numbers go, and happens to have this data there: 00008440 6f 00 6e 00 66 00 69 00 67 00 75 00 72 00 65 00 |o.n.f.i.g.u.r.e.| 00008450 00 00 49 00 50 00 76 00 36 00 28 00 00 00 2c 00 |..I.P.v.6.(...,.| 00008460 25 00 73 00 2c 00 00 00 29 00 00 00 25 00 64 00 |%.s.,...)...%.d.| 00008470 2e 00 25 00 64 00 2e 00 25 00 64 00 2e 00 25 00 |..%.d...%.d...%.| 00008480 64 00 00 00 44 00 48 00 43 00 50 00 00 00 49 00 |d...D.H.C.P...I.| 00008490 50 00 76 00 34 00 28 00 00 00 2c 00 25 00 73 00 |P.v.4.(...,.%.s.| And so that table is, in theory, this part: 00008447 00 67 00 75 00 72 00 65 00 | .g.u.r.e.| 00008450 00 |. | Which is pretty clearly not a pointer table of any kind. So give ia32 the same treatment as x86_64, and now all arches work basically the same. Signed-off-by: Peter Jones <pjones@redhat.com>
2014-09-21Generate a sane PE header on shim, fallback, and MokManager.Peter Jones
It turns out a7249a65 was masking a second problem - on some binaries, when we actually don't have any base relocations at all, binutils' "objcopy --target efi-app-x86_64" is generating a PE header with a base relocations pointer that happily points into the middle of our text section. So with shim processing base relocations correctly, it refuses to load those binaries. For example, on one binary I just built: 00000130 00 a0 00 00 0a 00 00 00 00 00 00 00 00 00 00 00 |................| which says there's a Base Relocation Table at 0xa000 that's 0xa bytes long. That's here: 0000a000 58 00 29 00 00 00 00 00 48 00 44 00 28 00 50 00 |X.).....H.D.(.P.| 0000a010 61 00 72 00 74 00 25 00 64 00 2c 00 53 00 69 00 |a.r.t.%.d.,.S.i.| 0000a020 67 00 25 00 67 00 29 00 00 00 00 00 00 00 00 00 |g.%.g.).........| 0000a030 48 00 44 00 28 00 50 00 61 00 72 00 74 00 25 00 |H.D.(.P.a.r.t.%.| So the table is: 0000a000 58 00 29 00 00 00 00 00 48 00 |X.).....H. | That wouldn't be so bad, except those binaries are MokManager.efi, fallback.efi, and shim.efi, and sometimes they're .reloc, which we're actually trying to handle correctly now because grub builds with a real and valid .reloc table. So though I didn't think there was any hair left on this yak, more shaving ensues. With this change, instead of letting objcopy do whatever it likes, we switch to "-O binary" and merely link in a header that's appropriate for our binaries. This is the same method Ard wrote for aarch64, and it seems to work fine in either place (modulo some minor changes.) At some point this should be merged into gnu-efi instead of carrying our own crt0-efi-x86_64.S, but that's a less immediate problem. I did not need this problem.
