The test case 87 ("perf record tests") failed on hybrid systems,the event
"cpu/br_inst_retired.near_call/p" is only for non-hybrid system. Correct
the test event to support both non-hybrid and hybrid systems.
Before:
# ./perf test 87
87: perf record tests : FAILED!
After:
# ./perf test 87
87: perf record tests : Ok
Fixes: 24f378e66021f559 ("perf test: Add basic perf record tests")

The printk code invokes vnsprintf in order to compute the complete
string before adding it into its buffer. This happens in an IRQ-off
region which leads to a warning on PREEMPT_RT in the random code if the
format strings contains a %p for pointer printing. This happens because
the random core acquires locks which become sleeping locks on PREEMPT_RT
which must not be acquired with disabled interrupts and or preemption
disabled.
By default the pointers are hashed which requires a random value on the
first invocation (either by printk or another user which comes first.
One could argue that there is no need for printk to disable interrupts
during the vsprintf() invocation which would fix the just mentioned
problem. However printk itself can be invoked in a context with
disabled interrupts which would lead to the very same problem.
Move the initialization of ptr_key into a worker and schedule it from
subsys_initcall(). This happens early but after the workqueue subsystem
is ready. Use get_random_bytes() to retrieve the random value if the RNG
core is ready, otherwise schedule a worker in two seconds and try again.
Another advantage is that it removes a lock from the vsprintf() code path.
It prevents a possible deadlock when printk("%p", ptr) is called under
the lock taken in get_random_bytes().

In case of fused compare and taken branch instructions, the AMD LBR points to
the compare instruction instead of the branch. Users of LBR usually expects
the from address to point to a branch instruction. The kernel has code to
adjust the from address via get_branch_type_fused(). However this correction
is only applied when a branch filter is applied. That means that if no
filter is present, the quality of the data is lower.
Fix the problem by applying the adjustment regardless of the filter setting,
bringing the AMD LBR to the same level as other LBR implementations.

offset is passed as a pointer and on certain call path is not set by the
function. If the caller does not re-initialize offset between calls, value
could be inherited between calls. Prevent this by initializing offset on each
call.
This impacts the code in amd_pmu_lbr_filter() which does:
for(i=0; ...) {
ret = get_branch_type_fused(..., &offset);
if (offset)
lbr_entries[i].from += offset;

The first two patches from a series by Kees Cook [1] that introduce
kmalloc_size_roundup(). This will allow merging of per-subsystem patches using
the new function and ultimately stop (ab)using ksize() in a way that causes
ongoing trouble for debugging functionality and static checkers.

Resolved a conflict of modifying mm/slab.c __ksize() comment with a commit that
unifies __ksize() implementation into mm/slab_common.c
|
|
A patch from Feng Tang that enhances the existing debugfs alloc_traces
file for kmalloc caches with information about how much space is wasted
by allocations that needs less space than the particular kmalloc cache
provides.

Additional cleanup by Chao Yu removing a BUG_ON() in create_unique_id().

In the effort to help the compiler reason about buffer sizes, the
__alloc_size attribute was added to allocators. This improves the scope
of the compiler's ability to apply CONFIG_UBSAN_BOUNDS and (in the near
future) CONFIG_FORTIFY_SOURCE. For most allocations, this works well,
as the vast majority of callers are not expecting to use more memory
than what they asked for.
There is, however, one common exception to this: anticipatory resizing
of kmalloc allocations. These cases all use ksize() to determine the
actual bucket size of a given allocation (e.g. 128 when 126 was asked
for). This comes in two styles in the kernel:
1) An allocation has been determined to be too small, and needs to be
resized. Instead of the caller choosing its own next best size, it
wants to minimize the number of calls to krealloc(), so it just uses
ksize() plus some additional bytes, forcing the realloc into the next
bucket size, from which it can learn how large it is now. For example:
data = krealloc(data, ksize(data) + 1, gfp);
data_len = ksize(data);
2) The minimum size of an allocation is calculated, but since it may
grow in the future, just use all the space available in the chosen
bucket immediately, to avoid needing to reallocate later. A good
example of this is skbuff's allocators:
data = kmalloc_reserve(size, gfp_mask, node, &pfmemalloc);
...
/* kmalloc(size) might give us more room than requested.
* Put skb_shared_info exactly at the end of allocated zone,
* to allow max possible filling before reallocation.
*/
osize = ksize(data);
size = SKB_WITH_OVERHEAD(osize);
In both cases, the "how much was actually allocated?" question is answered
_after_ the allocation, where the compiler hinting is not in an easy place
to make the association any more. This mismatch between the compiler's
view of the buffer length and the code's intention about how much it is
going to actually use has already caused problems[1]. It is possible to
fix this by reordering the use of the "actual size" information.
We can serve the needs of users of ksize() and still have accurate buffer
length hinting for the compiler by doing the bucket size calculation
_before_ the allocation. Code can instead ask "how large an allocation
would I get for a given size?".
Introduce kmalloc_size_roundup(), to serve this function so we can start
replacing the "anticipatory resizing" uses of ksize().

The __malloc attribute should not be applied to "realloc" functions, as
the returned pointer may alias the storage of the prior pointer. Instead
of splitting __malloc from __alloc_size, which would be a huge amount of
churn, just create __realloc_size for the few cases where it is needed.
Thanks to Geert Uytterhoeven <geert@linux-m68k.org> for reporting build
failures with gcc-8 in earlier version which tried to remove the #ifdef.
While the "alloc_size" attribute is available on all GCC versions, I
forgot that it gets disabled explicitly by the kernel in GCC < 9.1 due
to misbehaviors. Add a note to the compiler_attributes.h entry for it.

that the state reflects that. Currently if there is a device failure,

Driver registration fails on SOC imx8mn as its supplier, the clock
control module, is probed later than subsys initcall level. This driver
uses platform_driver_probe which is not compatible with deferred probing
and won't be probed again later if probe function fails due to clock not
being available at that time.
This patch replaces the use of platform_driver_probe with
platform_driver_register which will allow probing the driver later again
when the clock control module will be available.
The __init annotation has been dropped because it is not compatible with
deferred probing. The code is not executed once and its memory cannot be
freed.

The Snapdragon 670 uses the QUSB driver for USB 2.0. Document the
compatible used in the device tree.

On SDM845 one of PCIe PHYs (the QHP one) has the same region for TX and
RX registers. Since the commit 4be26f695ffa ("phy: qcom-qmp-pcie: fix
memleak on probe deferral") added checking that resources are not
allocated beforehand, this PHY can not be probed anymore. Fix this by
skipping the map of ->rx resource on the QHP PHY and assign it manually.

Remove the unused ieee80211_hw* parameter, and pass ieee80211_hdr*
instead of relying on skb->data having the right value at the time
the function is called.
This doesn't change the functionality at all.

ieee80211_tx_queue_params.aifs is not supposed to be written directly
to the REG_EDCA_*_PARAM registers. Instead process it like the vendor
drivers do. It's kinda hacky but it works.
This change boosts the download speed and makes it more stable.
Tested with RTL8188FU but all the other supported chips should also
benefit.

The module parameter ht40_2g was supposed to enable 40 MHz operation,
but it didn't.
Tell the firmware about the channel width when updating the rate mask.
This makes it work with my gen 2 chip RTL8188FU.
I'm not sure if anything needs to be done for the gen 1 chips, if 40
MHz channel width already works or not. They update the rate mask with
a different structure which doesn't have a field for the channel width.
Also set the channel width correctly for sta_statistics.

The rockchip,pipe-grf property is only used on rk3588, but not on
rk3568. Therefore this property is not present on rk3568 devices,
leading to the following message:
rockchip-snps-pcie3-phy fe8c0000.phy: failed to find rockchip,pipe_grf regmap
Fix that by only looking for this property on rk3588.
