[ Upstream commit 3a735530c1 ]
In general, the three SKUs of sc7180 (lite, normal, and pro) are
handled dynamically.
The cpufreq table in sc7180.dtsi includes the superset of all CPU
frequencies. The "qcom-cpufreq-hw" driver in Linux shows that we can
dynamically detect which frequencies are actually available on the
currently running CPU and then we can just enable those ones.
The GPU is similarly dynamic. The nvmem has a fuse in it (see
"gpu_speed_bin" in sc7180.dtsi) that the GPU driver can use to figure
out which frequencies to enable.
There is one part, however, that is not so dynamic. The way SDRAM
frequency works in sc7180 is that it's tied to cpufreq. At the busiest
cpufreq operating points we'll pick the top supported SDRAM frequency.
They ramp down together.
For the "pro" SKU of sc7180, we only enable one extra cpufreq step.
That extra cpufreq step runs SDRAM at the same speed as the step
below. Thus, for normal and pro things are OK. There is no sc7180-pro
device tree snippet.
For the "lite" SKU if sc7180, however, things aren't so easy. The
"lite" SKU drops 3 cpufreq entries but can still run SDRAM at max
frequency. That messed things up with the whole scheme. This is why we
added the "sc7180-lite" fragment in commit 8fd01e01fd ("arm64: dts:
qcom: sc7180-lite: Tweak DDR/L3 scaling on SC7180-lite").
When the lite scheme came about, it was agreed that the WiFi SKUs of
lazor would _always_ be "lite" and would, in fact, be the only "lite"
devices. Unfortunately, this decision changed and folks didn't realize
that it would be a problem. Specifically, some later lazor WiFi-only
devices were built with "pro" CPUs.
Building WiFi-only lazor with "pro" CPUs isn't the end of the world.
The SDRAM will ramp up a little sooner than it otherwise would, but
aside from a small power hit things work OK. One problem, though, is
that the SDRAM scaling becomes a bit quirky. Specifically, with the
current tables we'll max out SDRAM frequency at 2.1GHz but then
_lower_ it at 2.2GHz / 2.3GHz only to raise it back to max for 2.4GHz
and 2.55GHz.
Let's at least fix this so that the SDRAM frequency doesn't go down in
that quirky way. On true "lite" SKUs this change will be a no-op
because the operating points we're touching are disabled. This change
is only useful when a board that thinks it has a "lite" CPU actually
has a "normal" or "pro" one stuffed.

[ Upstream commit ccd4923d18 ]
The of_find_device_by_node() function is returning a struct platform_device
object with the embedded struct device member's reference counter
incremented. This needs to be dropped when done with the platform device
returned by of_find_device_by_node().
at91_pm_eth_quirk_is_valid() calls of_find_device_by_node() on
suspend and resume path. On suspend it calls of_find_device_by_node() and
on resume and failure paths it drops the counter of
struct platform_device::dev.
In case ethernet device may not wakeup there is a put_device() on
at91_pm_eth_quirk_is_valid() which is wrong as it colides with
put_device() on resume path leading to the reference counter of struct
device embedded in struct platform_device to be messed, stack trace to be
displayed (after 5 consecutive suspend/resume cycles) and execution to
hang.
Along with this the error path of at91_pm_config_quirks() had been also
adapted to decrement propertly the reference counter of struct device
embedded in struct platform_device.

commit 81a31a860b upstream.
Without EXCLUSIVE_SYSTEM_RAM, users are allowed to map arbitrary
physical memory regions into the userspace via /dev/mem. At the same
time, pages may change their properties (e.g., from anonymous pages to
named pages) while they are still being mapped in the userspace, leading
to "corruption" detected by the page table check.
To avoid these false positives, this patch makes PAGE_TABLE_CHECK
depends on EXCLUSIVE_SYSTEM_RAM. This dependency is understandable
because PAGE_TABLE_CHECK is a hardening technique but /dev/mem without
STRICT_DEVMEM (i.e., !EXCLUSIVE_SYSTEM_RAM) is itself a security
problem.
Even with EXCLUSIVE_SYSTEM_RAM, I/O pages may be still allowed to be
mapped via /dev/mem. However, these pages are always considered as named
pages, so they won't break the logic used in the page table check.

commit d0b861653f upstream.
When hcd->localmem_pool is non-null, localmem_pool is used to allocate
DMA memory. In this case, the dma address will be properly returned (in
dma_handle), and dma_mmap_coherent should be used to map this memory
into the user space. However, the current implementation uses
pfn_remap_range, which is supposed to map normal pages.
Instead of repeating the logic in the memory allocation function, this
patch introduces a more robust solution. Here, the type of allocated
memory is checked by testing whether dma_handle is properly set. If
dma_handle is properly returned, it means some DMA pages are allocated
and dma_mmap_coherent should be used to map them. Otherwise, normal
pages are allocated and pfn_remap_range should be called. This ensures
that the correct mmap functions are used consistently, independently
with logic details that determine which type of memory gets allocated.

commit 0143d148d1 upstream.
The current implementation of usbdev_mmap uses usb_alloc_coherent to
allocate memory pages that will later be mapped into the user space.
Meanwhile, usb_alloc_coherent employs three different methods to
allocate memory, as outlined below:
* If hcd->localmem_pool is non-null, it uses gen_pool_dma_alloc to
allocate memory;
* If DMA is not available, it uses kmalloc to allocate memory;
* Otherwise, it uses dma_alloc_coherent.
However, it should be noted that gen_pool_dma_alloc does not guarantee
that the resulting memory will be page-aligned. Furthermore, trying to
map slab pages (i.e., memory allocated by kmalloc) into the user space
is not resonable and can lead to problems, such as a type confusion bug
when PAGE_TABLE_CHECK=y [1].
To address these issues, this patch introduces hcd_alloc_coherent_pages,
which addresses the above two problems. Specifically,
hcd_alloc_coherent_pages uses gen_pool_dma_alloc_align instead of
gen_pool_dma_alloc to ensure that the memory is page-aligned. To replace
kmalloc, hcd_alloc_coherent_pages directly allocates pages by calling
__get_free_pages.

of fast-diff states (OBJECT_EXISTS vs OBJECT_EXISTS_CLEAN) and object

forked for the snapshot isn't guaranteed to accurately reflect the
contents of the snapshot when the snapshot is taken under I/O. This
breaks differential backup and snapshot-based mirroring use cases with
fast-diff enabled: since some object deltas may be incomplete, the

commit 2a84aea80e upstream.
This patch addresses an issue within the j1939_sk_send_loop_abort()
function in the j1939/socket.c file, specifically in the context of
Transport Protocol (TP) sessions.
Without this patch, when a TP session is initiated and a Clear To Send
(CTS) frame is received from the remote side requesting one data packet,
the kernel dispatches the first Data Transport (DT) frame and then waits
for the next CTS. If the remote side doesn't respond with another CTS,
the kernel aborts due to a timeout. This leads to the user-space
receiving an EPOLLERR on the socket, and the socket becomes active.
However, when trying to read the error queue from the socket with
sock.recvmsg(, , socket.MSG_ERRQUEUE), it returns -EAGAIN,
given that the socket is non-blocking. This situation results in an
infinite loop: the user-space repeatedly calls epoll(), epoll() returns
the socket file descriptor with EPOLLERR, but the socket then blocks on
the recv() of ERRQUEUE.
This patch introduces an additional check for the J1939_SOCK_ERRQUEUE
flag within the j1939_sk_send_loop_abort() function. If the flag is set,
it indicates that the application has subscribed to receive error queue
messages. In such cases, the kernel can communicate the current transfer
state via the error queue. This allows for the function to return early,
preventing the unnecessary setting of the socket into an error state,
and breaking the infinite loop. It is crucial to note that a socket
error is only needed if the application isn't using the error queue, as,
without it, the application wouldn't be aware of transfer issues.

kmemdup() at line 2735 is not duplicating enough memory for
notif->tid_tear_down and notif->station_id. As it only duplicates
612 bytes: up to offsetofend(struct iwl_wowlan_info_notif,
received_beacons), this is the range of [0, 612) bytes.
2735 notif = kmemdup(notif_v1,
2736 offsetofend(struct iwl_wowlan_info_notif,
2737 received_beacons),
2738 GFP_ATOMIC);
which evidently does not cover bytes 612 and 613 for members
tid_tear_down and station_id in struct iwl_wowlan_info_notif.
See below:

/* --- cacheline 7 boundary (448 bytes) was 40 bytes ago --- */

u8 reserved2[2]; /* 614 2 */
/* size: 616, cachelines: 10, members: 13 */
/* last cacheline: 40 bytes */
};
Therefore, when the following assignments take place, actually no memory
has been allocated for those objects:
2743 notif->tid_tear_down = notif_v1->tid_tear_down;
2744 notif->station_id = notif_v1->station_id;
Fix this by allocating space for the whole notif object and zero out the
remaining space in memory after member station_id.
This also fixes the following -Warray-bounds issues:

commit feee70f456 upstream.
While doing my research to improve the xpad device names I noticed
that the 1532:0037 VID/PID seems to be used by the DeathAdder 2013,
so that Razer Sabertooth instance looked wrong and very suspect to
me. I didn't see any mention in the official drivers, either.
After doing more research, it turns out that the xpad list
is used by many other projects (like Steam) as-is [1], this
issue was reported [2] and Valve/Sam Lantinga fixed it [3]:
[1]: dcc5eef0e2/src/joystick/controller_type.h (L251)
[2]: https://steamcommunity.com/app/353380/discussions/0/1743392486228754770/
[3]: https://hg.libsdl.org/SDL/rev/29809f6f0271
(With multiple Internet users reporting similar issues, not linked here)
After not being able to find the correct VID/PID combination anywhere
on the Internet and not receiving any reply from Razer support I did
some additional detective work, it seems like it presents itself as
"Razer Sabertooth Gaming Controller (XBOX360)", code 1689:FE00.
Leaving us with this:
* Razer Sabertooth (1689:fe00)
* Razer Sabertooth Elite (24c6:5d04)
* Razer DeathAdder 2013 (1532:0037) [note: not a gamepad]
So, to sum things up; remove this conflicting/duplicate entry:
{ 0x1532, 0x0037, "Razer Sabertooth", 0, XTYPE_XBOX360 },
As the real/correct one is already present there, even if
the Internet as a whole insists on presenting it as the
Razer Sabertooth Elite, which (by all accounts) is not:
{ 0x1689, 0xfe00, "Razer Sabertooth", 0, XTYPE_XBOX360 },
