In xemaclite_open() function we are setting the max speed of
emaclite to 100Mb using phy_set_max_speed() function so,
there is no need to write the advertising registers to stop
giga-bit speed and the phy_start() function starts the
auto-negotiation so, there is no need to handle it separately
using advertising registers. Remove the phy_read and phy_write
of advertising registers in xemaclite_open() function.

nfcmrvl_nci_unregister_dev to avoid bugs
There are destructive operations such as nfcmrvl_fw_dnld_abort and
gpio_free in nfcmrvl_nci_unregister_dev. The resources such as firmware,
gpio and so on could be destructed while the upper layer functions such as
nfcmrvl_fw_dnld_start and nfcmrvl_nci_recv_frame is executing, which leads
to double-free, use-after-free and null-ptr-deref bugs.
There are three situations that could lead to double-free bugs.
The first situation is shown below:
(Thread 1) | (Thread 2)
nfcmrvl_fw_dnld_start |
... | nfcmrvl_nci_unregister_dev
release_firmware() | nfcmrvl_fw_dnld_abort
kfree(fw) //(1) | fw_dnld_over
| release_firmware
... | kfree(fw) //(2)
| ...
The second situation is shown below:
(Thread 1) | (Thread 2)
nfcmrvl_fw_dnld_start |
... |
mod_timer |
(wait a time) |
fw_dnld_timeout | nfcmrvl_nci_unregister_dev
fw_dnld_over | nfcmrvl_fw_dnld_abort
release_firmware | fw_dnld_over
kfree(fw) //(1) | release_firmware
... | kfree(fw) //(2)
The third situation is shown below:
(Thread 1) | (Thread 2)
nfcmrvl_nci_recv_frame |
if(..->fw_download_in_progress)|
nfcmrvl_fw_dnld_recv_frame |
queue_work |
|
fw_dnld_rx_work | nfcmrvl_nci_unregister_dev
fw_dnld_over | nfcmrvl_fw_dnld_abort
release_firmware | fw_dnld_over
kfree(fw) //(1) | release_firmware
| kfree(fw) //(2)
The firmware struct is deallocated in position (1) and deallocated
in position (2) again.
The crash trace triggered by POC is like below:
BUG: KASAN: double-free or invalid-free in fw_dnld_over
Call Trace:
kfree
fw_dnld_over
nfcmrvl_nci_unregister_dev
nci_uart_tty_close
tty_ldisc_kill
tty_ldisc_hangup
__tty_hangup.part.0
tty_release
...
What's more, there are also use-after-free and null-ptr-deref bugs
in nfcmrvl_fw_dnld_start. If we deallocate firmware struct, gpio or
set null to the members of priv->fw_dnld in nfcmrvl_nci_unregister_dev,
then, we dereference firmware, gpio or the members of priv->fw_dnld in
nfcmrvl_fw_dnld_start, the UAF or NPD bugs will happen.
This patch reorders destructive operations after nci_unregister_device
in order to synchronize between cleanup routine and firmware download
routine.
The nci_unregister_device is well synchronized. If the device is
detaching, the firmware download routine will goto error. If firmware
download routine is executing, nci_unregister_device will wait until
firmware download routine is finished.

Based on DesignWare Ethernet QoS datasheet, we are seeing the limitation
of Split Header (SPH) feature is not supported for Ipv4 fragmented packet.
This SPH limitation will cause ping failure when the packets size exceed
the MTU size. For example, the issue happens once the basic ping packet
size is larger than the configured MTU size and the data is lost inside
the fragmented packet, replaced by zeros/corrupted values, and leads to
ping fail.
So, disable the Split Header for Intel platforms.
v2: Add fixes tag in commit message.
Fixes: 67afd6d1cfdf("net: stmmac: Add Split Header support and enable it in XGMAC cores")

In ipmi_ipmb_probe(), 'iidev->intf' is not set before
ipmi_register_smi() success. And in the error handling case,
ipmi_ipmb_remove() is called to release resources, ipmi_unregister_smi()
is called without check 'iidev->intf', this will cause KASAN

General kernel style is to allow NULL to be passed into unregister

The previous split budget between TX and RX made it return not using
the entire budget but at the same time not having calling called
napi_complete. This sometimes led to the poll to not be called, and at
the same time having TX and RX interrupts disabled resulting in the
driver getting stuck.

Use the device of the device tree node should be rather than the
device of the struct net_device when allocating DMA buffers.
The driver got away with it on sparc32 until commit 53b7670e5735
("sparc: factor the dma coherent mapping into helper") after which the
driver oopses.

There are deadlocks caused by del_timer_sync(&priv->hang_timer) and
del_timer_sync(&priv->rr_timer) in grcan_close(), one of the deadlocks
are shown below:
(Thread 1) | (Thread 2)
| grcan_reset_timer()
grcan_close() | mod_timer()
spin_lock_irqsave() //(1) | (wait a time)
... | grcan_initiate_running_reset()
del_timer_sync() | spin_lock_irqsave() //(2)
(wait timer to stop) | ...
We hold priv->lock in position (1) of thread 1 and use
del_timer_sync() to wait timer to stop, but timer handler also need
priv->lock in position (2) of thread 2. As a result, grcan_close()
will block forever.
This patch extracts del_timer_sync() from the protection of
spin_lock_irqsave(), which could let timer handler to obtain the
needed lock.

This reverts commit 723ad916134784b317b72f3f6cf0f7ba774e5dae
When client requests channel or ring size larger than what the server
can support the server will cap the request to the supported max. So,
the client would not be able to successfully request resources that
exceed the server limit.

The Time-Specified Departure feature is indeed mutually exclusive with
TX IP checksumming in ENETC, but TX checksumming in itself is broken and
was removed from this driver in commit 82728b91f124 ("enetc: Remove Tx
checksumming offload code").
The blamed commit declared NETIF_F_HW_CSUM in dev->features to comply
with software TSO's expectations, and still did the checksumming in
software by calling skb_checksum_help(). So there isn't any restriction
for the Time-Specified Departure feature.
However, enetc_setup_tc_txtime() doesn't understand that, and blindly
looks for NETIF_F_CSUM_MASK.
Instead of checking for things which can literally never happen in the
current code base, just remove the check and let the driver offload
tc-etf qdiscs.

Arm SMMU fixes for 5.18
- Fix off-by-one in SMMUv3 SVA TLB invalidation
- Disable large mappings to workaround nvidia erratum
|
|
The page fault handling framework in the IOMMU core explicitly states
that it doesn't handle PCI PASID Stop Marker and the IOMMU drivers must
discard them before reporting faults. This handles Stop Marker messages
in prq_event_thread() before reporting events to the core.
The VT-d driver explicitly drains the pending page requests when a CPU
page table (represented by a mm struct) is unbound from a PASID according
to the procedures defined in the VT-d spec. The Stop Marker messages do
not need a response. Hence, it is safe to drop the Stop Marker messages
silently if any of them is found in the page request queue.

Calculate the appropriate mask for non-size-aligned page selective
invalidation. Since psi uses the mask value to mask out the lower order
bits of the target address, properly flushing the iotlb requires using a
mask value such that [pfn, pfn+pages) all lie within the flushed
size-aligned region. This is not normally an issue because iova.c
always allocates iovas that are aligned to their size. However, iovas
which come from other sources (e.g. userspace via VFIO) may not be
aligned.
To properly flush the IOTLB, both the start and end pfns need to be
equal after applying the mask. That means that the most efficient mask
to use is the index of the lowest bit that is equal where all higher
bits are also equal. For example, if pfn=0x17f and pages=3, then
end_pfn=0x181, so the smallest mask we can use is 8. Any differences
above the highest bit of pages are due to carrying, so by xnor'ing pfn
and end_pfn and then masking out the lower order bits based on pages, we
get 0xffffff00, where the first set bit is the mask we want to use.
