When building for the UM arch and neither INDIRECT_IOMEM=y, nor
HAS_IOMEM=y is selected, it will fall back to the implementations from
asm-generic/io.h for IO memcpy. But these fall-back functions just do a
memcpy. So, instead of depending on UML, add dependency on 'HAS_IOMEM ||
INDIRECT_IOMEM'.

Kuniyuki Iwashima says:
====================
rtnetlink: Handle error of rtnl_register_module().
While converting phonet to per-netns RTNL, I found a weird comment
/* Further rtnl_register_module() cannot fail */
that was true but no longer true after commit addf9b90de22 ("net:
rtnetlink: use rcu to free rtnl message handlers").
Many callers of rtnl_register_module() just ignore the returned
value but should handle them properly.
This series introduces two helpers, rtnl_register_many() and
rtnl_unregister_many(), to do that easily and fix such callers.
All rtnl_register() and rtnl_register_module() will be converted
to _many() variant and some rtnl_lock() will be saved in _many()
later in net-next.
Changes:

* Add more context in changelog of each patch
v3: https://lore.kernel.org/all/20241007124459.5727-1-kuniyu@amazon.com/

Before commit addf9b90de22 ("net: rtnetlink: use rcu to free rtnl
message handlers"), once the first rtnl_register_module() allocated
rtnl_msg_handlers[PF_PHONET], the following calls never failed.
However, after the commit, rtnl_register_module() could fail silently
to allocate rtnl_msg_handlers[PF_PHONET][msgtype] and requires error
handling for each call.
Handling the error allows users to view a module as an all-or-nothing
thing in terms of the rtnetlink functionality. This prevents syzkaller
from reporting spurious errors from its tests, where OOM often occurs
and module is automatically loaded.
Let's use rtnl_register_many() to handle the errors easily.

Before commit addf9b90de22 ("net: rtnetlink: use rcu to free rtnl message
handlers"), once rtnl_msg_handlers[protocol] was allocated, the following
rtnl_register_module() for the same protocol never failed.
However, after the commit, rtnl_msg_handler[protocol][msgtype] needs to
be allocated in each rtnl_register_module(), so each call could fail.
Many callers of rtnl_register_module() do not handle the returned error,
and we need to add many error handlings.
To handle that easily, let's add wrapper functions for bulk registration
of rtnetlink message handlers.

The parameters for the diag 0x258 are real addresses, not virtual, but
KVM was using them as virtual addresses. This only happened to work, since
the Linux kernel as a guest used to have a 1:1 mapping for physical vs
virtual addresses.
Fix KVM so that it correctly uses the addresses as real addresses.

Previously, access_guest_page() did not check whether the given guest
address is inside of a memslot. This is not a problem, since
kvm_write_guest_page/kvm_read_guest_page return -EFAULT in this case.
However, -EFAULT is also returned when copy_to/from_user fails.
When emulating a guest instruction, the address being outside a memslot
usually means that an addressing exception should be injected into the
guest.
Failure in copy_to/from_user however indicates that something is wrong
in userspace and hence should be handled there.
To be able to distinguish these two cases, return PGM_ADDRESSING in
access_guest_page() when the guest address is outside guest memory. In
access_guest_real(), populate vcpu->arch.pgm.code such that
kvm_s390_inject_prog_cond() can be used in the caller for injecting into
the guest (if applicable).
Since this adds a new return value to access_guest_page(), we need to make
sure that other callers are not confused by the new positive return value.
There are the following users of access_guest_page():
- access_guest_with_key() does the checking itself (in
guest_range_to_gpas()), so this case should never happen. Even if, the
handling is set up properly.
- access_guest_real() just passes the return code to its callers, which
are:
- read_guest_real() - see below
- write_guest_real() - see below
There are the following users of read_guest_real():
- ar_translation() in gaccess.c which already returns PGM_*
- setup_apcb10(), setup_apcb00(), setup_apcb11() in vsie.c which always
return -EFAULT on read_guest_read() nonzero return - no change
- shadow_crycb(), handle_stfle() always present this as validity, this
could be handled better but doesn't change current behaviour - no change
There are the following users of write_guest_real():
- kvm_s390_store_status_unloaded() always returns -EFAULT on
write_guest_real() failure.

A crypto card comes in 3 flavors: accelerator, CCA co-processor or
EP11 co-processor. Within a protected execution environment only the
accelerator and EP11 co-processor is supported. However, it is
possible to set up a KVM guest with a CCA card and run it as a
protected execution guest. There is nothing at the host side which
prevents this. Within such a guest, a CCA card is shown as "illicit"
and you can't do anything with such a crypto card.
Regardless of the unsupported CCA card within a protected execution
guest there are a couple of user space applications which
unconditional try to run crypto requests to the zcrypt device
driver. There was a bug within the AP bus code which allowed such a
request to be forwarded to a CCA card where it is finally
rejected and the driver reacts with -ENODEV but also triggers an AP
bus scan. Together with a retry loop this caused some kind of "hang"
of the KVM guest. On startup it caused timeouts and finally led the
KVM guest startup fail. Fix that by closing the gap and make sure a
CCA card is not usable within a protected execution environment.
Another behavior within an protected execution environment with CCA
cards was that the se_bind and se_associate AP queue sysfs attributes
where shown. The implementation unconditional always added these
attributes. Fix that by checking if the card mode is supported within
a protected execution environment and only if valid, add the attribute
group.

The Linux implementation of PCI error recovery for s390 was based on the
understanding that firmware error recovery is a two step process with an
optional initial error event to indicate the cause of the error if known
followed by either error event 0x3A (Success) or 0x3B (Failure) to
indicate whether firmware was able to recover. While this has been the
case in testing and the error cases seen in the wild it turns out this
is not correct. Instead firmware only generates 0x3A for some error and
service scenarios and expects the OS to perform recovery for all PCI
events codes except for those indicating permanent error (0x3B, 0x40)
and those indicating errors on the function measurement block (0x2A,
0x2B, 0x2C). Align Linux behavior with these expectations.

Commit adding support for multiple control interfaces expanded struct
snd_usb_power_domain with pointer to control interface for proper control
message routing but missed one initialization point of this structure,
which has left new field with NULL value.
Standard mandates that each device has at least one control interface and
code responsible for power domain does not check for NULL values when
querying for control interface. This caused some USB devices to crash
the kernel.

While working with the T-Head 1520 LicheePi4A SoC, certain conditions
arose that allowed me to reproduce a race issue in the sdhci code.
To reproduce the bug, you need to enable the sdio1 controller in the
device tree file
`arch/riscv/boot/dts/thead/th1520-lichee-module-4a.dtsi` as follows:
&sdio1 {
bus-width = <4>;
max-frequency = <100000000>;
no-sd;
no-mmc;
broken-cd;
cap-sd-highspeed;
post-power-on-delay-ms = <50>;
status = "okay";
wakeup-source;
keep-power-in-suspend;
};
When resetting the SoC using the reset button, the following messages
appear in the dmesg log:

Here's what happens: the __mmc_start_request function is called with
opcode 5. Since the power to the Wi-Fi card, which resides on this SDIO
bus, is initially off after the reset, an interrupt SDHCI_INT_TIMEOUT is
triggered. Immediately after that, a second interrupt SDHCI_INT_RESPONSE
is triggered. Depending on the exact timing, these conditions can
trigger the following race problem:
1) The sdhci_cmd_irq top half handles the command as an error. It sets
host->cmd to NULL and host->pending_reset to true.
2) The sdhci_thread_irq bottom half is scheduled next and executes faster
than the second interrupt handler for SDHCI_INT_RESPONSE. It clears
host->pending_reset before the SDHCI_INT_RESPONSE handler runs.
3) The pending interrupt SDHCI_INT_RESPONSE handler gets called, triggering
a code path that prints: "mmc2: Got command interrupt 0x00000001 even
though no command operation was in progress."
To solve this issue, we need to clear pending interrupts when resetting
host->pending_reset. This ensures that after sdhci_threaded_irq restores
interrupts, there are no pending stale interrupts.
The behavior observed here is non-compliant with the SDHCI standard.
Place the code in the sdhci-of-dwcmshc driver to account for a
hardware-specific quirk instead of the core SDHCI code.

This is 0x6108 + offset 0x44 from the beginning of sdw_stream_add_slave()
where data abort happens.
wsa881x_hw_params() is called with stream = NULL and passes it further
in register x4 (5th argument) to sdw_stream_add_slave() without any checks.
Value from x4 is copied to x25 and finally it aborts on trying to load
a value from address in x25 plus offset 32 (in dec) which corresponds
to master_list member in struct sdw_stream_runtime:
struct sdw_stream_runtime {
const char * name; /* 0 8 */
struct sdw_stream_params params; /* 8 12 */
enum sdw_stream_state state; /* 20 4 */
enum sdw_stream_type type; /* 24 4 */
/* XXX 4 bytes hole, try to pack */
here-> struct list_head master_list; /* 32 16 */
int m_rt_count; /* 48 4 */
/* size: 56, cachelines: 1, members: 6 */
/* sum members: 48, holes: 1, sum holes: 4 */
/* padding: 4 */
/* last cacheline: 56 bytes */
Fix this by adding required calls to qcom_snd_sdw_startup() and
sdw_release_stream() to startup and shutdown routines which restores
the previous correct behaviour when ->set_stream() method is called to
set a valid stream runtime pointer on playback startup.
Reproduced and then fix was tested on db845c RB3 board.

While we do currently return -EFAULT in this case, it seems prudent to
follow the behaviour of other syscalls like clone3. It seems quite
unlikely that anyone depends on this error code being EFAULT, but we can
always revert this if it turns out to be an issue.

dst_entries_add() uses per-cpu data that might be freed at netns
dismantle from ip6_route_net_exit() calling dst_entries_destroy()
Before ip6_route_net_exit() can be called, we release all
the dsts associated with this netns, via calls to dst_release(),
which waits an rcu grace period before calling dst_destroy()
dst_entries_add() use in dst_destroy() is racy, because
dst_entries_destroy() could have been called already.
Decrementing the number of dsts must happen sooner.
Notes:
1) in CONFIG_XFRM case, dst_destroy() can call
dst_release_immediate(child), this might also cause UAF
if the child does not have DST_NOCOUNT set.
IPSEC maintainers might take a look and see how to address this.
2) There is also discussion about removing this count of dst,
which might happen in future kernels.

The previous patch removed the ENOENT warning at the point of
allocation, but the overall self-test warning is still there.
Fix all of them by returning zero as the test result. This is
safe because if the algorithm has gone away, then it cannot be
marked as tested.

As algorithm testing is carried out without holding the main crypto
lock, it is always possible for the algorithm to go away during the
test.
So before crypto_alg_tested updates the status of the tested alg,
it checks whether it's still on the list of all algorithms. This
is inaccurate because it may be off the main list but still on the
list of algorithms to be removed.
Updating the algorithm status is safe per se as the larval still
holds a reference to it. However, killing spawns of other algorithms
that are of lower priority is clearly a deficiency as it adds
unnecessary churn.
Fix the test by checking whether the algorithm is dead.

Since X86_FEATURE_ENTRY_IBPB will invalidate all harmful predictions
with IBPB, no software-based untraining of returns is needed anymore.
Currently, this change affects retbleed and SRSO mitigations so if
either of the mitigations is doing IBPB and the other one does the
software sequence, the latter is not needed anymore.

entry_ibpb() is designed to follow Intel's IBPB specification regardless
of CPU. This includes invalidating RSB entries.
Hence, if IBPB on VMEXIT has been selected, entry_ibpb() as part of the
RET untraining in the VMEXIT path will take care of all BTB and RSB
clearing so there's no need to explicitly fill the RSB anymore.

entry_ibpb() should invalidate all indirect predictions, including return
target predictions. Not all IBPB implementations do this, in which case the
fallback is RSB filling.
Prevent SRSO-style hijacks of return predictions following IBPB, as the return
target predictor can be corrupted before the IBPB completes.

Set this flag if the CPU has an IBPB implementation that does not
invalidate return target predictions. Zen generations < 4 do not flush
the RSB when executing an IBPB and this bug flag denotes that.

AMD's initial implementation of IBPB did not clear the return address
predictor. Beginning with Zen4, AMD's IBPB *does* clear the return address
predictor. This behavior is enumerated by CPUID.80000008H:EBX.IBPB_RET[30].
Define X86_FEATURE_AMD_IBPB_RET for use in KVM_GET_SUPPORTED_CPUID,
when determining cross-vendor capabilities.

Commit 5a498d4d06d6 ("drm/fbdev-dma: Only install deferred I/O if
necessary") initializes deferred I/O only if it is used.
drm_fbdev_dma_fb_destroy() however calls fb_deferred_io_cleanup()
unconditionally with struct fb_info.fbdefio == NULL. KASAN with the
out-of-tree Apple silicon display driver posts following warning from
__flush_work() of a random struct work_struct instead of the expected
NULL pointer derefs.

====================
Intel Wired LAN Driver Updates 2024-10-08 (ice, i40e, igb, e1000e)
This series contains updates to ice, i40e, igb, and e1000e drivers.
For ice:
Marcin allows driver to load, into safe mode, when DDP package is
missing or corrupted and adjusts the netif_is_ice() check to
account for when the device is in safe mode. He also fixes an
out-of-bounds issue when MSI-X are increased for VFs.
Wojciech clears FDB entries on reset to match the hardware state.
For i40e:
Aleksandr adds locking around MACVLAN filters to prevent memory |
