Various bug fixes
- Fix grub.cfg boot counting snippet generation (lorbus) Resolves: rhbz#1614637 - Fix spurrious allocation error reporting on EFI boot Resolves: rhbz#1635319 - Stop doing TPM on BIOS *again*. It just doesn't work. Related: rhbz#1579835 - Make blscfg module loadable on older grub2 i386-pc and powerpc-ieee1275 builds - Fix execstack cropping up in grub2-tools - Ban stack trampolines with compiler flags.

Subject: [PATCH] drop TPM support for legacy BIOS
|
||||
|
||||
Currently there's TPM support for both EFI and legacy BIOS.
|
||||
|
||||
A software interrupt call interface is used in legacy BIOS to communicate
|
||||
with the TPM chips. But with some BIOS firmwares, the machine just hangs
|
||||
after doing a BIOS interrupt call for the TCG_HashLogExtendEvent command.
|
||||
|
||||
It's hard to know what exactly is causing this, but the Trousers project
|
||||
mentions in their docs that they don't use TCG_HashLogExtendEvent [0] due
|
||||
the command not working reliable on some BIOS.
|
||||
|
||||
The TCG_CompactHashLogExtendEvent is less fragile, since it has a simpler
|
||||
interface, doesn't require to setup any data structure and doesn't return
|
||||
anything. So it could be used to do measurements and logs events instead.
|
||||
|
||||
But even when using this command can be a workaround on some systems, it
|
||||
doesn't guarantee that could not fail on others. So since the TPM support
|
||||
for some legacy BIOS don't work and can lead to machines failing to boot,
|
||||
let's just drop it and only support TPM for EFI.

|
||||
Subject: [PATCH] Move quicksort function from kernel.exec to the blscfg module
|
||||
|
||||
The qsort function is defined in the grub2 kernel and exported for modules
|
||||
to use. But this prevents the blscfg.mod to be loaded by old grub2 kernels
|
||||
that don't export this symbol.
|
||||
|
||||
Loading the latest blscfg module might be useful on legacy BIOS systems to
|
||||
avoid updating the first and second stage grub2 images in the boot device.
|
||||
|
||||
Since the only caller of the qsort function is the blscfg module, move the
|
||||
qsort function out of the grub2 kernel and only have it in the blscfg.mod.
|
||||
|
||||
While being there, also remove the grub_bsearch() function that is unused.
