hw/scsi: avoid deadlock upon TMF request cancelling with VirtIO
Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
When scsi_req_dequeue() is reached via
scsi_req_cancel_async()
virtio_scsi_tmf_cancel_req()
virtio_scsi_do_tmf_aio_context(),
there is a deadlock when trying to acquire the SCSI device's requests
lock, because it was already acquired in
virtio_scsi_do_tmf_aio_context().
In particular, the issue happens with a FreeBSD guest (13, 14, 15,
maybe more), when it cancels SCSI requests, because of timeout.
This is a regression caused by commit da6eebb33b ("virtio-scsi:
perform TMFs in appropriate AioContexts") and the introduction of the
requests_lock earlier.
To fix the issue, only cancel the requests after releasing the
requests_lock. For this, the SCSI device's requests are iterated while
holding the requests_lock and the requests to be cancelled are
collected in a list. Then, the collected requests are cancelled
one by one while not holding the requests_lock. This is safe, because
only requests from the current AioContext are collected and acted
upon.

This usage flag was deprecated by RFC8813, such that it is
forbidden to be present for certs using ECDSA/ECDH algorithms,
and in TLS 1.3 is conceptually obsolete.
As such many valid certs will no longer have this key usage
flag set, and QEMU should not be rejecting them, as this
prevents use of otherwise valid & desirable algorithms.

The existing implementation assumes that client/server certificates are
single individual certificates. If using publicly-issued certificates,
or internal CAs that use an intermediate issuer, this is unlikely to be
the case, and they will instead be certificate chains. While this can
be worked around by moving the intermediate certificates to the CA
certificate, which DOES currently support multiple certificates, this
instead allows the issued certificate chains to be used as-is, without
requiring the overhead of shuffling certificates around.

The loop that checks the CA certificate chain can fail to report
an error message if one of the certs in the chain has an issuer
that is not present in the chain. In this case, the outer loop
'while (checking_issuer)' will terminate after failing to find

The QIOChannelWebsock object releases all its resources in the
finalize callback. This is later than desired, as callers expect
to be able to call qio_channel_close() to fully close a channel
and release resources related to I/O.
The logic in the finalize method is at most a failsafe to handle
cases where a consumer forgets to call qio_channel_close.
This adds equivalent logic to the close method to release the
resources, using g_clear_handle_id/g_clear_pointer to be robust
against repeated invocations. The finalize method is tweaked
so that the GSource is removed before releasing the underlying
channel.

While code is supposed to call qio_channel_close() before releasing the
last reference on an QIOChannel, this is not guaranteed. QIOChannelFile
and QIOChannelSocket both cleanup resources in their finalizer if the
close operation was missed.
This ensures the TLS channel will do the same failsafe cleanup.

The way that premature termination was handled in TLS connections was
changed to handle an ordering problem during graceful shutdown in the
migration code.
Unfortunately one of the codepaths returned -1 to indicate an error
condition, but failed to set the 'errp' parameter.
This broke error handling in the qio_channel_tls_handshake function,
as the QTask callback would no longer see that an error was raised.
As a result, the client will go on to try to use the already closed
TLS connection, resulting in misleading errors.
This was evidenced in the I/O test 233 which showed changes such as
-qemu-nbd: Certificate does not match the hostname localhost

This patch ensure pmpcfg and pmpaddr comply with WARL constraints.
When the PMP granularity is greater than 4 bytes, NA4 mode is not valid
per the spec and will be silently ignored.
According to the spec, changing pmpcfg.A only affects the "read" value
of pmpaddr. When G > 2 and pmpcfg.A is NAPOT, bits pmpaddr[G-2:0] read
as all ones. When G > 1 and pmpcfg.A is OFF or TOR, bits pmpaddr[G-1:0]
read as all zeros. This allows software to read back the correct
granularity value.
In addition, when updating the PMP address rule in TOR mode,
the start and end addresses of the PMP region should be aligned
to the PMP granularity. (The current SPEC only state in TOR mode
that bits pmpaddr[G-1:0] do not affect the TOR address-matching logic.)

Previously, the PMP granularity in qemu always used a minimum
granularity of 4 bytes, this patch add pmp-granularity to allow
platforms to configure the value.
A new CPU parameter pmp-granularity has been introduced to the QEMU
command line. For example:
-cpu rv64, g=true, c=true, pmp=true, pmp-granularity=1024
If no specific value is provided, the default value is 4 bytes.

riscv_cpu_validate_v() left its variable, min_vlen, uninitialized if
no vector extension is available, causing a compiler warning.
Re-define riscv_cpu_validate_v() as no-op when no vector extension is
available to prevent the scenario that will read the unintialized
variable by construction. It also simplifies its caller as a bonus.

We're filtering out (MIP_VSSIP | MIP_VSTIP | MIP_VSEIP) from S-mode
pending interrupts without apparent reason. There's no special treatment
for these ints as far as the spec goes, and this filtering is causing
read_stopi() to miss those VS interrupts [1].
We shouldn't return delegated VS interrupts in S-mode though, so change
the current mask with "~env->hideleg". Note that this is the same
handling we're doing in riscv_cpu_mirq_pending() and env->mideleg.

Coverity CID 1641401 reports that, in reg_is_ulong_integer(), we're
dereferencing a NULL pointer in "reg1" when using it in strcasecmp()
call. A similar case is reported with CID 1641393.
In theory that will never happen - it's guaranteed that both "reg1" and
"reg2" is non-NULL because we're retrieving them in compile-time from
static arrays. Coverity doesn't know that though.
To make Coverity happier and add a bit more clarity in the code,
g_assert() each token to make it clear that those 2 values aren't
supposed to be NULL ever. Do that in both reg_is_ulong_integer() and
reg_is_u64_fpu().
We're also taking the opportunity to implement suggestions made by Peter
in [1] in both functions:
- use g_strsplit() instead of strtok();
- use g_ascii_strcasecmp() instead of strcasecmp().

This patch was originally made by Gitlab user Bo Gan (@ganboing) 4
months ago in the context of issue [1]. I asked the author to send a
patch to the mailing list ~3 months ago and got no reply. I'm sending
the patch myself because we already missed 10.1 without this fix.
I'll also just post verbatim Bo Gan comment in the commit msg:
"In RISCV Linux with KVM enabled, gdbstub is broken. The
get_physical_address isn't able to page-walk correctly and resolve the
physical page. This is due to that the vcpu is being treated as starting
in M mode even if KVM enabled. However, with KVM, the vcpu is actually
started in S mode. The mmu_idx will give 3 (M), instead of 1 (S),
resulting in Guest PA == VA (wrong)!"
Set env->priv to PRV_S in kvm_riscv_reset_regs_csr() since the VCPU is
always started in S-mode for KVM.

The Linux kernel checks the PCS disabled bit in the R_DESCONF register
to determine if SGMII is supported. If the bit is set, SGMII support is
disabled. Since the Microchip Icicle devicetree file configures SGMII
interface mode, enabling the Ethernet interfaces fails when booting
the Linux kernel.
Add pcs-enabled property to to let the driver know if PCS should be
enabled. Set the flag to false by default (indicating that PCS is disabled)
to match the exiting code.

The Microchip PolarFire SoC Icicle Kit supports two Ethernet interfaces.
The PHY on each may be connected to separate MDIO busses, or both may be
connected on the same MDIO bus using different PHY addresses.
To be able to support two PHY instances on a single MDIO bus, two properties
are needed: First, there needs to be a flag indicating if the MDIO bus on
a given Ethernet interface is connected. If not, attempts to read from this
bus must always return 0xffff. Implement this property as phy-connected.
Second, if the MDIO bus on an interface is active, it needs a link to the
consumer interface to be able to provide PHY access for it. Implement this
property as phy-consumer.

In of_dpa_mask2prefix() we do "(2 << i)" for a loop where i can go up
to 31. At i == 31 we shift off the top end of an integer. This
doesn't actually calculate the wrong value in practice, because we
calculate 0 - 1 which is the 0xffffffff mask we wanted (and for QEMU
shifting off the top of a signed integer is not UB); but it makes
Coverity complain.
We could fix this simply by using "2ULL" (where the "(2ULL << i) - 1"
expression also evaluates to 0xffffffff for i == 31), but in fact
this function is a slow looping implementation of counting the number
of trailing zeroes in the (network-order) input mask:
0bxxxxxxxxx1 => 32
0bxxxxxxxx10 => 31
0bxxxxxxx100 => 30
...
0bx100000000 => 2
0b1000000000 => 1
0b0000000000 => 0
Replace the implementation with 32 - ctz32().

GDB expects the TLS registers to be exposed via org.gnu.gdb.aarch64.tls,
which will contain either just "tpidr", or else "tpidr" and "tpidr2".
This will be important for SME in future, because the lazy state
restoration scheme requires GDB to use the TPIDR2 information.
GDB doesn't currently implement that, but we should provide the
register via the XML so that we are ready when future GDB versions
support it.

For SME2, we need to expose the new ZT0 register in the gdbstub XML.
gdb documents that the requirements are:
> The ‘org.gnu.gdb.aarch64.sme2’ feature is optional. If present,
> then the ‘org.gnu.gdb.aarch64.sme’ feature must also be present.
> The ‘org.gnu.gdb.aarch64.sme2’ feature should contain the

Implement this.
