9ea3164611 9pfs: fix removing non-existent POSIX ACL xattr on macOS host
When mapped POSIX ACL is used, we are ignoring errors when trying
to remove a POSIX ACL xattr that does not exist. On Linux hosts we
would get ENODATA in such cases, on macOS hosts however we get
ENOATTR instead.

As we can be sure that ENOATTR is defined as being identical on Linux
hosts (at least by qemu/xattr.h), it is safe to fix this issue by
simply comparing against ENOATTR instead of ENODATA.

This patch fixes e.g. a command on Linux guest like:

  cp --preserve=mode old new

951fe2f89f 9pfs: fix wrong errno being sent to Linux client on macOS host
Linux and macOS only share some errno definitions with equal macro
name and value. In fact most mappings for errno are completely
different on the two systems.

This patch converts some important errno values from macOS host to
corresponding Linux errno values before eventually sending such error
codes along with 'Rlerror' replies (if 9p2000.L is used that is). Not
having translated errnos before violated the 9p2000.L protocol spec,
which says:

  "
  size[4] Rlerror tag[2] ecode[4]

  ... ecode is a numerical Linux errno.
  "

  https://github.com/chaos/diod/wiki/protocol#lerror----return-error-code

This patch fixes a bunch of misbehaviours when running a Linux client
on macOS host. For instance this patch fixes:

  mount -t 9p -o posixacl ...

on Linux guest if security_mode=mapped was used for 9p server, which
refused to mount successfully, because macOS returned ENOATTR==93
when client tried to retrieve POSIX ACL xattrs, because errno 93
is defined as EPROTONOSUPPORT==93 on Linux, so Linux client believed
that xattrs were not supported by filesystem on host in general.

e5c88e2264 9pfs: fix wrong encoding of rdev field in Rgetattr on macOS
The 'rdev' field in 9p reponse 'Rgetattr' is of type dev_t,
which is actually a system dependant type and therefore both the
size and encoding of dev_t differ between macOS and Linux.

So far we have sent 'rdev' to guest in host's dev_t format as-is,
which caused devices to appear with wrong device numbers on
guests running on macOS hosts, eventually leading to various
misbehaviours on guest in conjunction with device files.

This patch fixes this issue by converting the device number from
host's dev_t format to Linux dev_t format. As 9p request
'Tgettattr' is exclusive to protocol version 9p2000.L, it should
be fair to assume that 'rdev' field is assumed to be in Linux dev_t
format by client as well.

0009df31cb 9pfs: fix inode sequencing in 'synth' driver
The 'synth' driver's root node and the 'synth' driver's first
subdirectory node falsely share the same inode number (zero), which
makes it impossible for 9p clients (i.e. 9p test cases) to distinguish
root node and first subdirectory from each other by comparing their QIDs
(which are derived by 9p server from driver's inode numbers).

Fix this issue by using prefix-increment instead of postfix-increment
operator while generating new inode numbers for subdirectories and files.

325b7c4e75 hw/riscv: Enable TPM backends
Imply the TPM sysbus devices. This allows users to add TPM devices to
the RISC-V virt board.

This was tested by first creating an emulated TPM device:

    swtpm socket --tpm2 -t -d --tpmstate dir=/tmp/tpm \
        --ctrl type=unixio,path=swtpm-sock

Then launching QEMU with:

    -chardev socket,id=chrtpm,path=swtpm-sock \
    -tpmdev emulator,id=tpm0,chardev=chrtpm \
    -device tpm-tis-device,tpmdev=tpm0

The TPM device can be seen in the memory tree and the generated device
tree.

457a86a0eb target/riscv: Fix incorrect PTE merge in walk_pte
Two non-subsequent PTEs can be mapped to subsequent paddrs. In this
case, walk_pte will erroneously merge them.

Enforce the split up, by tracking the virtual base address.

Let's say we have the mapping:
0x81200000 -> 0x89623000 (4K)
0x8120f000 -> 0x89624000 (4K)

Before, walk_pte would have shown:

vaddr            paddr            size             attr
---------------- ---------------- ---------------- -------
0000000081200000 0000000089623000 0000000000002000 rwxu-ad

as it only checks for subsequent paddrs. With this patch, it becomes:

vaddr            paddr            size             attr
---------------- ---------------- ---------------- -------
0000000081200000 0000000089623000 0000000000001000 rwxu-ad

Commit 7c28f4da20 ("RISC-V: Don't add NULL bootargs to device-tree")
tried to avoid adding *NULL* bootargs to device tree, but unfortunately
the changes were entirely useless, due to MachineState::kernel_cmdline
can't be NULL at all as the default value is given as an empty string.
(see hw/core/machine.c::machine_initfn()).

Note the wording of *NULL* bootargs is wrong. It can't be NULL otherwise
a segfault had already been observed by dereferencing the NULL pointer.
It should be worded as *empty" bootargs.

f8e7163d9e hw/arm/smmuv3: Advertise support for SMMUv3.2-BBML2
The Arm SMMUv3 includes an optional feature equivalent to the CPU
FEAT_BBM, which permits an OS to switch a range of memory between
"covered by a huge page" and "covered by a sequence of normal pages"
without having to engage in the traditional 'break-before-make'
dance. (This is particularly important for the SMMU, because devices
performing I/O through an SMMU are less likely to be able to cope with
the window in the sequence where an access results in a translation
fault.)  The SMMU spec explicitly notes that one of the valid ways to
be a BBM level 2 compliant implementation is:
 * if there are multiple entries in the TLB for an address,
   choose one of them and use it, ignoring the others

Our SMMU TLB implementation (unlike our CPU TLB) does allow multiple
TLB entries for an address, because the translation table level is
part of the SMMUIOTLBKey, and so our IOTLB hashtable can include
entries for the same address where the leaf was at different levels
(i.e. both hugepage and normal page). Our TLB lookup implementation in
smmu_iotlb_lookup() will always find the entry with the lowest level
(i.e. it prefers the hugepage over the normal page) and ignore any
others. TLB invalidation correctly removes all TLB entries matching
the specified address or address range (unless the guest specifies the
leaf level explicitly, in which case it gets what it asked for). So we
can validly advertise support for BBML level 2.

Note that we still can't yet advertise ourselves as an SMMU v3.2,
because v3.2 requires support for the S2FWB feature, which we don't
yet implement.

75d08a4072 target/arm: Advertise support for FEAT_BBM level 2
The description in the Arm ARM of the requirements of FEAT_BBM is
admirably clear on the guarantees it provides software, but slightly
more obscure on what that means for implementations.  The description
of the equivalent SMMU feature in the SMMU specification (IHI0070D.b
section 3.21.1) is perhaps a bit more detailed and includes some
example valid implementation choices. (The SMMU version of this
feature is slightly tighter than the CPU version: the CPU is permitted
to raise TLB Conflict aborts in some situations that the SMMU may
not. This doesn't matter for QEMU because we don't want to do TLB
Conflict aborts anyway.)

The informal summary of FEAT_BBM is that it is about permitting an OS
to switch a range of memory between "covered by a huge page" and
"covered by a sequence of normal pages" without having to engage in
the 'break-before-make' dance that has traditionally been
necessary. The 'break-before-make' sequence is:

 * replace the old translation table entry with an invalid entry
 * execute a DSB insn
 * execute a broadcast TLB invalidate insn
 * execute a DSB insn
 * write the new translation table entry
 * execute a DSB insn

The point of this is to ensure that no TLB can simultaneously contain
TLB entries for the old and the new entry, which would traditionally
be UNPREDICTABLE (allowing the CPU to generate a TLB Conflict fault
or to use a random mishmash of values from the old and the new
entry).  FEAT_BBM level 2 says "for the specific case where the only
thing that changed is the size of the block, the TLB is guaranteed
not to do weird things even if there are multiple entries for an
address", which means that software can now do:

 * replace old translation table entry with new entry
 * DSB
 * broadcast TLB invalidate
 * DSB

As the SMMU spec notes, valid ways to do this include:

 * if there are multiple entries in the TLB for an address,
   choose one of them and use it, ignoring the others
 * if there are multiple entries in the TLB for an address,
   throw them all out and do a page table walk to get a new one

QEMU's page table walk implementation for Arm CPUs already meets the
requirements for FEAT_BBM level 2. When we cache an entry in our TCG
TLB, we do so only for the specific (non-huge) page that the address
is in, and there is no way for the TLB data structure to ever have
more than one TLB entry for that page. (We handle huge pages only in
that we track what part of the address space is covered by huge pages
so that a TLB invalidate operation for an address in a huge page
results in an invalidation of the whole TLB.) We ignore the Contiguous
bit in page table entries, so we don't have to do anything for the
parts of FEAT_BBM that deal with changis to the Contiguous bit.

FEAT_BBM level 2 also requires that the nT bit in block descriptors
must be ignored; since commit 39a1fd2528 we do this.

It's therefore safe for QEMU to advertise FEAT_BBM level 2 by
setting ID_AA64MMFR2_EL1.BBM to 2.

f81c60c244 target/arm: Advertise support for FEAT_TTL
The Arm FEAT_TTL architectural feature allows the guest to provide an
optional hint in an AArch64 TLB invalidate operation about which
translation table level holds the leaf entry for the address being
invalidated.  QEMU's TLB implementation doesn't need that hint, and
we correctly ignore the (previously RES0) bits in TLB invalidate
operation values that are now used for the TTL field.  So we can
simply advertise support for it in our 'max' CPU.

ced716942a hw/arm/smmuv3: Cache event fault record
The Record bit in the Context Descriptor tells the SMMU to report fault
events to the event queue. Since we don't cache the Record bit at the
moment, access faults from a cached Context Descriptor are never
reported. Store the Record bit in the cached SMMUTransCfg.

eb851c1151 target/arm: Disable cryptographic instructions when neon is disabled
As of now, cryptographic instructions ISAR fields are never cleared so
we can end up with a cpu with cryptographic instructions but no
floating-point/neon instructions which is not a possible configuration
according to Arm specifications.

In QEMU, we have 3 kinds of cpus regarding cryptographic instructions:
+ no support
+ cortex-a57/a72: cryptographic extension is optional,
  floating-point/neon is not.
+ cortex-a53: crytographic extension is optional as well as
  floating-point/neon. But cryptographic requires
  floating-point/neon support.

Therefore we can safely clear the ISAR fields when neon is disabled.

Note that other Arm cpus seem to follow this. For example cortex-a55 is
like cortex-a53 and cortex-a76/cortex-a710 are like cortex-a57/a72.
