Sven Schnelle b5e0b3d742 s390/ipl: add missing intersection check to ipl_report handling
commit a52e5cdbe8 upstream.

The code which handles the ipl report is searching for a free location
in memory where it could copy the component and certificate entries to.
It checks for intersection between the sections required for the kernel
and the component/certificate data area, but fails to check whether
the data structures linking these data areas together intersect.

This might cause the iplreport copy code to overwrite the iplreport
itself. Fix this by adding two addtional intersection checks.

Vasily Gorbik 55dbd6f4ea s390/decompressor: specify __decompress() buf len to avoid overflow
[ Upstream commit 7ab41c2c08 ]

Historically calls to __decompress() didn't specify "out_len" parameter
on many architectures including s390, expecting that no writes beyond
uncompressed kernel image are performed. This has changed since commit
2aa14b1ab2 ("zstd: import usptream v1.5.2") which includes zstd library
commit 6a7ede3dfccb ("Reduce size of dctx by reutilizing dst buffer
(#2751)"). Now zstd decompression code might store literal buffer in
the unwritten portion of the destination buffer. Since "out_len" is
not set, it is considered to be unlimited and hence free to use for
optimization needs. On s390 this might corrupt initrd or ipl report
which are often placed right after the decompressor buffer. Luckily the
size of uncompressed kernel image is already known to the decompressor,
so to avoid the problem simply specify it in the "out_len" parameter.

Alexander Egorenkov 37a88b41dc s390/boot: fix use of expolines in the DMA code
commit 463f36c76f upstream.

The DMA code section of the decompressor must be compiled with expolines
if Spectre V2 mitigation has been enabled for the decompressed kernel.
This is required because although the decompressor's image contains
the DMA code section, it is handed over to the decompressed kernel for use.

Because the DMA code is already slow w/o expolines, use expolines always
regardless whether the decompressed kernel is using them or not. This
simplifies the DMA code by dropping the conditional compilation of
expolines.

Heiko Carstens a50b56ffc0 s390/mem_detect: fix tprot() program check new psw handling
[ Upstream commit da90575767 ]

The tprot() inline asm temporarily changes the program check new psw
to redirect a potential program check on the diag instruction.
Restoring of the program check new psw is done in C code behind the
inline asm.

This can be problematic, especially if the function is inlined, since
the compiler can reorder instructions in such a way that a different
instruction, which may result in a program check, might be executed
before the program check new psw has been restored.

To avoid such a scenario move restoring into the inline asm. For
consistency reasons move also saving of the original program check new
psw into the inline asm.

Heiko Carstens 7e1e0235b3 s390/mem_detect: fix diag260() program check new psw handling
[ Upstream commit 86807f348f ]

The __diag260() inline asm temporarily changes the program check new
psw to redirect a potential program check on the diag instruction.
Restoring of the program check new psw is done in C code behind the
inline asm.

This can be problematic, especially if the function is inlined, since
the compiler can reorder instructions in such a way that a different
instruction, which may result in a program check, might be executed
before the program check new psw has been restored.

To avoid such a scenario move restoring into the inline asm. For
consistency reasons move also saving of the original program check new
psw into the inline asm.

Janosch Frank 36ae903607 s390: mm: Fix secure storage access exception handling
commit 85b18d7b5e upstream.

Turns out that the bit 61 in the TEID is not always 1 and if that's
the case the address space ID and the address are
unpredictable. Without an address and its address space ID we can't
export memory and hence we can only send a SIGSEGV to the process or
panic the kernel depending on who caused the exception.

Unfortunately bit 61 is only reliable if we have the "misc" UV feature
bit.

Janosch Frank 9218a6b031 s390: uv: Fix sysfs max number of VCPUs reporting
commit e82080e1f4 upstream.

The number reported by the query is N-1 and I think people reading the
sysfs file would expect N instead. For users creating VMs there's no
actual difference because KVM's limit is currently below the UV's
limit.

Andrey Konovalov b243efc9b4 UPSTREAM: kasan, x86, s390: update undef CONFIG_KASAN
[ Upstream commit 8a494023b8 ]

With the intoduction of hardware tag-based KASAN some kernel checks of
this kind:

  ifdef CONFIG_KASAN

will be updated to:

  if defined(CONFIG_KASAN_GENERIC) || defined(CONFIG_KASAN_SW_TAGS)

x86 and s390 use a trick to #undef CONFIG_KASAN for some of the code
that isn't linked with KASAN runtime and shouldn't have any KASAN
annotations.

Also #undef CONFIG_KASAN_GENERIC with CONFIG_KASAN.

Vasily Gorbik 3ca8b855b0 s390/startup: add kaslr_offset to pgm check info print
startup pgm check handler is active since the very beginning of kernel
code execution until uncompressed kernel sets up s390_base_pgm_handler.

It is useful not just for the decompressor debugging itself, but also for
early code of uncompressed kernel, in particular Kasan initialization. But
since there is no stack trace or symbolic representation of failing psw
address it is impossible to figure out faulty code location without
knowing Kaslr kernel base. So, let's add it to the startup pgm check
info printed as well.

Vasily Gorbik 5c46f2768c s390/kaslr: correct and explain randomization base generation
Currently there are several minor problems with randomization base
generation code:

1. It might misbehave in low memory conditions. In particular there
might be enough space for the kernel on [0, block_sum] but after
	if (base < safe_addr)
		base = safe_addr;
it might not be enough anymore.

2. It does not correctly handle minimal address constraint. In condition
	if (base < safe_addr)
		base = safe_addr;
a synthetic value is compared with an address. If we have a memory
setup with memory holes due to offline memory regions, and safe_addr is
close to the end of the first online memory block - we might position
the kernel in invalid memory.

3. block_sum calculation logic contains off-by-one error. Let's say we
have a memory block in which the kernel fits perfectly
(end - start == kernel_size). In this case:
		if (end - start < kernel_size)
			continue;
		block_sum += end - start - kernel_size;
block_sum is not increased, while it is a valid kernel position.

So, address problems listed and explain algorithm used. Besides that
restructuring the code makes it possible to extend kernel positioning
algorithm further. Currently we pick position in between single
[min, max] range (min = safe_addr, max = memory_limit). In future we
can do that for multiple ranges as well (by calling
count_valid_kernel_positions for each range).

install" not depend on vmlinux"), the install targets should never
trigger the rebuild of the kernel.

The variable, CONFIGURE, is not set by anyone. Remove it as well.

Christian Borntraeger 27dc0700c3 s390/uv: Fix handling of length extensions
The query parameter block might contain additional information and can
be extended in the future. If the size of the block does not suffice we
get an error code of rc=0x100.  The buffer will contain all information
up to the specified size and the hypervisor/guest simply do not need the
additional information as they do not know about the new data.  That
means that we can (and must) accept rc=0x100 as success.

Sven Schnelle 17248ea036 s390: fix __EMIT_BUG() macro
Setting a kprobe on getname_flags() failed:

$ echo 'p:tmr1 getname_flags +0(%r2):ustring' > kprobe_events
-bash: echo: write error: Invalid argument

Debugging the kprobes code showed that the address of
getname_flags() is contained in the __bug_table. Kprobes
doesn't allow to set probes at BUG() locations.

$ objdump -j  __bug_table -x build/fs/namei.o
[..]
0000000000000108 R_390_PC32        .text+0x00000000000075a8
000000000000010c R_390_PC32        .L223+0x0000000000000004

I was expecting getname_flags() to start with a BUG(), but:

7598:       e3 20 10 00 00 04       lg      %r2,0(%r1)
759e:       c0 f4 00 00 00 00       jg      759e <putname+0x7e>
75a0: R_390_PLT32DBL    kmem_cache_free+0x2
75a4:       a7 f4 00 01             j       75a6 <putname+0x86>

00000000000075a8 <getname_flags>:
75a8:       c0 04 00 00 00 00       brcl    0,75a8 <getname_flags>
75ae:       eb 6f f0 48 00 24       stmg    %r6,%r15,72(%r15)
75b4:       b9 04 00 ef             lgr     %r14,%r15
75b8:       e3 f0 ff a8 ff 71       lay     %r15,-88(%r15)

So the BUG() is actually the last opcode of the previous function.
Fix this by switching to using the MONITOR CALL (MC) instruction,
and set the entry in __bug_table to the beginning of that MC.

Gerald Schaefer a9f2f6865d s390/kaslr: store KASLR offset for early dumps
The KASLR offset is added to vmcoreinfo in arch_crash_save_vmcoreinfo(),
so that it can be found by crash when processing kernel dumps.

However, arch_crash_save_vmcoreinfo() is called during a subsys_initcall,
so if the kernel crashes before that, we have no vmcoreinfo and no KASLR
offset.

Fix this by storing the KASLR offset in the lowcore, where the vmcore_info
pointer will be stored, and where it can be found by crash. In order to
make it distinguishable from a real vmcore_info pointer, mark it as uneven
(KASLR offset itself is aligned to THREAD_SIZE).

When arch_crash_save_vmcoreinfo() stores the real vmcore_info pointer in
the lowcore, it overwrites the KASLR offset. At that point, the KASLR
offset is not yet added to vmcoreinfo, so we also need to move the
mem_assign_absolute() behind the vmcoreinfo_append_str().

Commit "bpf: Process in-kernel BTF" in linux-next introduced an undefined

the message "Unknown relocation type".
