Subject: [PATCH] ieee1275: drop HEAP_MAX_ADDR, HEAP_MIN_SIZE
HEAP_MAX_ADDR is confusing. Currently it is set to 32MB, except
on ieee1275 on x86, where it is 64MB.
There is a comment which purports to explain it:
/* If possible, we will avoid claiming heap above this address, because it
seems to cause relocation problems with OSes that link at 4 MiB */
This doesn't make a lot of sense when the constants are well above 4MB
already. It was not always this way. Prior to
commit 7b5d0fe4440c ("Increase heap limit") in 2010, HEAP_MAX_SIZE and
HEAP_MAX_ADDR were indeed 4MB. However, when the constants were increased
the comment was left unchanged.
It's been over a decade. It doesn't seem like we have problems with
claims over 4MB on powerpc or x86 ieee1275. (sparc does things completely
differently and never used the constant.)
Drop the constant and the check.
The only use of HEAP_MIN_SIZE was to potentially override the
HEAP_MAX_ADDR check. It is now unused. Remove it.

Subject: [PATCH] ieee1275: claim more memory
On powerpc-ieee1275, we are running out of memory trying to verify
anything. This is because:
- we have to load an entire file into memory to verify it. This is
extremely difficult to change with appended signatures.
- We only have 32MB of heap.
- Distro kernels are now often around 30MB.
So we want to claim more memory from OpenFirmware for our heap.
There are some complications:
- The grub mm code isn't the only thing that will make claims on
memory from OpenFirmware:
* PFW/SLOF will have claimed some for their own use.
* The ieee1275 loader will try to find other bits of memory that we
haven't claimed to place the kernel and initrd when we go to boot.
* Once we load Linux, it will also try to claim memory. It claims
memory without any reference to /memory/available, it just starts
at min(top of RMO, 768MB) and works down. So we need to avoid this
area. See arch/powerpc/kernel/prom_init.c as of v5.11.
- The smallest amount of memory a ppc64 KVM guest can have is 256MB.
It doesn't work with distro kernels but can work with custom kernels.
We should maintain support for that. (ppc32 can boot with even less,
and we shouldn't break that either.)
- Even if a VM has more memory, the memory OpenFirmware makes available
as Real Memory Area can be restricted. A freshly created LPAR on a
PowerVM machine is likely to have only 256MB available to OpenFirmware
even if it has many gigabytes of memory allocated.
EFI systems will attempt to allocate 1/4th of the available memory,
clamped to between 1M and 1600M. That seems like a good sort of
approach, we just need to figure out if 1/4 is the right fraction
for us.
We don't know in advance how big the kernel and initrd are going to be,
which makes figuring out how much memory we can take a bit tricky.
To figure out how much memory we should leave unused, I looked at:
- an Ubuntu 20.04.1 ppc64le pseries KVM guest:
vmlinux: ~30MB
initrd: ~50MB
- a RHEL8.2 ppc64le pseries KVM guest:
vmlinux: ~30MB
initrd: ~30MB
Ubuntu VMs struggle to boot with just 256MB under SLOF.
RHEL likewise has a higher minimum supported memory figure.
So lets first consider a distro kernel and 512MB of addressible memory.
(This is the default case for anything booting under PFW.) Say we lose
131MB to PFW (based on some tests). This leaves us 381MB. 1/4 of 381MB
is ~95MB. That should be enough to verify a 30MB vmlinux and should
leave plenty of space to load Linux and the initrd.
If we consider 256MB of RMA under PFW, we have just 125MB remaining. 1/4
of that is a smidge under 32MB, which gives us very poor odds of verifying
a distro-sized kernel. However, if we need 80MB just to put the kernel
and initrd in memory, we can't claim any more than 45MB anyway. So 1/4
will do. We'll come back to this later.
grub is always built as a 32-bit binary, even if it's loading a ppc64
kernel. So we can't address memory beyond 4GB. This gives a natural cap
of 1GB for powerpc-ieee1275.
Also apply this 1/4 approach to i386-ieee1275, but keep the 32MB cap.
make check still works for both i386 and powerpc and I've booted
powerpc grub with this change under SLOF and PFW.

Subject: [PATCH] ieee1275: request memory with ibm,client-architecture-support
On PowerVM, the first time we boot a Linux partition, we may only get
256MB of real memory area, even if the partition has more memory.
This isn't really enough. Fortunately, the Power Architecture Platform
Reference (PAPR) defines a method we can call to ask for more memory.
This is part of the broad and powerful ibm,client-architecture-support
(CAS) method.
CAS can do an enormous amount of things on a PAPR platform: as well as
asking for memory, you can set the supported processor level, the interrupt
controller, hash vs radix mmu, and so on. We want to touch as little of
this as possible because we don't want to step on the toes of the future OS.
If:
- we are running under what we think is PowerVM (compatible property of /
begins with "IBM"), and
- the full amount of RMA is less than 512MB (as determined by the reg
property of /memory)
then call CAS as follows: (refer to the Linux on Power Architecture
Reference, LoPAR, which is public, at B.5.2.3):
- Use the "any" PVR value and supply 2 option vectors.
- Set option vector 1 (PowerPC Server Processor Architecture Level)
to "ignore".
- Set option vector 2 with default or Linux-like options, including a
min-rma-size of 512MB.
This will cause a CAS reboot and the partition will restart with 512MB
of RMA. Grub will notice the 512MB and not call CAS again.
(A partition can be configured with only 256MB of memory, which would
mean this request couldn't be satisfied, but PFW refuses to load with
only 256MB of memory, so it's a bit moot. SLOF will run fine with 256MB,
but we will never call CAS under qemu/SLOF because /compatible won't
begin with "IBM".)
One of the first things Linux does while still running under OpenFirmware
is to call CAS with a much fuller set of options (including asking for
512MB of memory). This includes a much more restrictive set of PVR values
and processor support levels, and this will induce another reboot. On this
reboot grub will again notice the higher RMA, and not call CAS. We will get
to Linux, Linux will call CAS but because the values are now set for Linux
this will not induce another CAS reboot and we will finally boot.
On all subsequent boots, everything will be configured with 512MB of RMA
and all the settings Linux likes, so there will be no further CAS reboots.
(phyp is super sticky with the RMA size - it persists even on cold boots.
So if you've ever booted Linux in a partition, you'll probably never have
grub call CAS. It'll only ever fire the first time a partition loads grub,
or if you deliberately lower the amount of memory your partition has below
512MB.)

Subject: [PATCH] appendedsig/x509: Also handle the Extended Key Usage
extension
Red Hat certificates have both Key Usage and Extended Key Usage extensions
present, but the appended signatures x509 parser doesn't handle the latter
and so buils due finding an unrecognised critical extension:
Error loading initial key:
../../grub-core/commands/appendedsig/x509.c:780:Unhandled critical x509 extension with OID 2.5.29.37
Fix this by also parsing the Extended Key Usage extension and handle it by
verifying that the certificate has a single purpose, that is code signing.

Subject: [PATCH] normal/main: Discover the device to read the config from as a
fallback
The GRUB core.img is generated locally, when this is done the grub2-probe
tool figures out the device and partition that needs to be read to parse
the GRUB configuration file.
But in some cases the core.img can't be generated on the host and instead
has to be done at package build time. For example, if needs to get signed
with a key that's only available on the package building infrastructure.
If that's the case, the prefix variable won't have a device and partition
but only a directory path. So there's no way for GRUB to know from which
device has to read the configuration file.
To allow GRUB to continue working on that scenario, fallback to iterating
over all the available devices, if reading the config failed when using
the prefix and fw_path variables.

Subject: [PATCH] powerpc: adjust setting of prefix for signed binary case
On RHEL-signed powerpc grub, we sign a grub with -p /grub2 and expect
that there's a boot partition.
Unfortunately grub_set_prefix_and_root tries to convert this to
($fwdevice)/grub2. This ends up being (ieee1275/disk)/grub2 and that
falls apart pretty quickly - there's no file-system on ieee1275/disk,
and it makes the search routine try things like
(ieee1275/disk,msdos2)(ieee1275/disk)/grub2 which also doesn't work.
Detect if we would be about to create (ieee1275/disk)/path and don't:
preserve a prefix of /path instead and hope the search later finds us.

Subject: [PATCH] powerpc: fix prefix + signed grub special case for PowerVM
Mea culpa: when testing the PowerPC special case for signed grub, I
assumed qemu and PowerVM would behave identically. This was wrong, and
with hindsight a pretty dumb error.
This fixes it. This time, I am actually testing on PowerVM.
