Merge tag 'sched_urgent_for_v5.11_rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull scheduler fix from Borislav Petkov:
"Revert an attempt to not spread IRQ threads on isolated CPUs which has
a bunch of problems"
* tag 'sched_urgent_for_v5.11_rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
Revert "lib: Restrict cpumask_local_spread to houskeeping CPUs"
This reverts commit 1abdfe706a579a702799fce465bceb9fb01d407c.
This change is broken and not solving any problem it claims to solve.
Robin reported that cpumask_local_spread() now returns any cpu out of
cpu_possible_mask in case that NOHZ_FULL is disabled (runtime or compile
time). It can also return any offline or not-present CPU in the
housekeeping mask. Before that it was returning a CPU out of
online_cpu_mask.
While the function is racy against CPU hotplug if the caller does not
protect against it, the actual use cases are not caring much about it as
they use it mostly as hint for:
- the user space affinity hint which is unused by the kernel
- memory node selection which is just suboptimal
- network queue affinity which might fail but is handled gracefully
But the occasional fail vs. hotplug is very different from returning
anything from possible_cpu_mask which can have a large amount of offline
CPUs obviously.
The changelog of the commit claims:
"The current implementation of cpumask_local_spread() does not respect
the isolated CPUs, i.e., even if a CPU has been isolated for Real-Time
task, it will return it to the caller for pinning of its IRQ
threads. Having these unwanted IRQ threads on an isolated CPU adds up
to a latency overhead."
The only correct part of this changelog is:
"The current implementation of cpumask_local_spread() does not respect
the isolated CPUs."
Everything else is just disjunct from reality.

When iteratively computing a checksum with csum_block_add, track the
offset "pos" to correctly rotate in csum_block_add when offset is odd.
The open coded implementation of skb_copy_and_csum_datagram did this.
With the switch to __skb_datagram_iter calling csum_and_copy_to_iter,
pos was reinitialized to 0 on each call.
Bring back the pos by passing it along with the csum to the callback.

iov_iter_advance() is heavily used, but implemented through generic
means. For bvecs there is a specifically crafted function for that, so
use bvec_iter_advance() instead, it's faster and slimmer.

zero-length bvec segments are allowed in general, but not handled by bio
and down the block layer so filtered out. This inconsistency may be
confusing and prevent from optimisations. As zero-length segments are
useless and places that were generating them are patched, declare them
not allowed.

The one in blake2b immediately overflows the 8KB stack area

Reference-count underflow for percpu_ref is detected in the RCU callback
percpu_ref_switch_to_atomic_rcu(), and the resulting warning does not
print anything allowing easy identification of which percpu_ref use
case is underflowing. This is of course not normally a problem when
developing a new percpu_ref use case because it is most likely that
the problem resides in this new use case. However, when deploying a
new kernel to a large set of servers, the underflow might well be a new
corner case in any of the old percpu_ref use cases.
This commit therefore calls mem_dump_obj() to dump out any additional
available information on the underflowing percpu_ref instance.

lib/test_fpu.c:66:0-23: WARNING: test_fpu_fops should be defined with DEFINE_DEBUGFS_ATTRIBUTE
Use DEFINE_DEBUGFS_ATTRIBUTE rather than DEFINE_SIMPLE_ATTRIBUTE
for debugfs files.
Semantic patch information:
Rationale: DEFINE_SIMPLE_ATTRIBUTE + debugfs_create_file()
imposes some significant overhead as compared to
DEFINE_DEBUGFS_ATTRIBUTE + debugfs_create_file_unsafe().
In order to protect against file removal races, debugfs files created
via debugfs_create_file() now get wrapped by a struct file_operations
at their opening.
If the original struct file_operations are known to be safe against
removal races by themselves already, the proxy creation may be bypassed
by creating the files through debugfs_create_file_unsafe().
In order to help debugfs users who use the common
DEFINE_SIMPLE_ATTRIBUTE() + debugfs_create_file() idiom to
transition to removal safe struct file_operations, the helper macro
DEFINE_DEBUGFS_ATTRIBUTE() has been introduced.
Thus, the preferred strategy is to use
DEFINE_DEBUGFS_ATTRIBUTE() + debugfs_create_file_unsafe()
now.

A subsequent patch will add additional atomic operations. These new
operations will use the same opcode field as the existing XADD, with
the immediate discriminating different operations.
In preparation, rename the instruction mode BPF_ATOMIC and start
calling the zero immediate BPF_ADD.
This is possible (doesn't break existing valid BPF progs) because the
immediate field is currently reserved MBZ and BPF_ADD is zero.
All uses are removed from the tree but the BPF_XADD definition is
kept around to avoid breaking builds for people including kernel
headers.

Older versions of BSD awk are fussy about the order of '-v' and '-f'
flags, and require a space after the flag name. This causes build
failures on platforms with an old awk, such as macOS and NetBSD.
Since GNU awk and modern versions of BSD awk (distributed with
FreeBSD/OpenBSD) are fine with either form, the definition of
'cmd_unroll' can be trivially tweaked to let the lib/raid6 Makefile
work with both old and new awk flag dialects.

In commit 11fb479ff5d9 ("zlib: export S390 symbols for zlib modules"), I
added EXPORT_SYMBOL()s to dfltcc_inflate.c but then Mikhail said that
these should probably be in dfltcc_syms.c with the other
EXPORT_SYMBOL()s.
However, that is contrary to the current kernel style, which places
EXPORT_SYMBOL() immediately after the function that it applies to, so
move all EXPORT_SYMBOL()s to their respective function locations and
drop the dfltcc_syms.c file. Also move MODULE_LICENSE() from the
deleted file to dfltcc.c.

Decompressing zlib streams on s390 fails with "incorrect data check"
error.
Userspace zlib checks inflate_state.flags in order to byteswap checksums
only for zlib streams, and s390 hardware inflate code, which was ported
from there, tries to match this behavior. At the same time, kernel zlib
does not use inflate_state.flags, so it contains essentially random
values. For many use cases either zlib stream is zeroed out or checksum
is not used, so this problem is masked, but at least SquashFS is still
affected.
Fix by always passing a checksum to and from the hardware as is, which
matches zlib_inflate()'s expectations.

Some graphic card has very big memory on chip, such as 32G bytes.
In the following case, it will cause overflow:
pool = gen_pool_create(PAGE_SHIFT, NUMA_NO_NODE);
ret = gen_pool_add(pool, 0x1000000, SZ_32G, NUMA_NO_NODE);
va = gen_pool_alloc(pool, SZ_4G);
The overflow occurs in gen_pool_alloc_algo_owner():
....
size = nbits << order;
....
The @nbits is "int" type, so it will overflow.
Then the gen_pool_avail() will return the wrong value.
This patch converts some "int" to "unsigned long", and
changes the compare code in while.

This is a preparatory commit for the upcoming addition of a new hardware
tag-based (MTE-based) KASAN mode.
The new mode won't be using shadow memory, but will still use the concept
of memory granules. Each memory granule maps to a single metadata entry:
8 bytes per one shadow byte for generic mode, 16 bytes per one shadow byte
for software tag-based mode, and 16 bytes per one allocation tag for
hardware tag-based mode.
Rename KASAN_SHADOW_SCALE_SIZE to KASAN_GRANULE_SIZE, and
KASAN_SHADOW_MASK to KASAN_GRANULE_MASK.
Also use MASK when used as a mask, otherwise use SIZE.
No functional changes.

* Support for stack tracing
* Support for strict /dev/mem
* Support for kernel section protection
I'm being a bit conservative on the cutoff for this round due to the
timing, so this is all the new development I'm going to take for this
cycle (even if some of it probably normally would have been OK). There
are, however, some fixes on the list that I will likely be sending along
either later this week or early next week.
There is one issue in here: one of my test configurations
(PREEMPT{,_DEBUG}=y) fails to boot on QEMU 5.0.0 (from April) as of the
.text.init alignment patch. With any luck we'll sort out the issue, but
given how many bugs get fixed all over the place and how unrelated those
features seem my guess is that we're just running into something that's
been lurking for a while and has already been fixed in the newer QEMU
(though I wouldn't be surprised if it's one of these implicit
assumptions we have in the boot flow). If it was hardware I'd be
strongly inclined to look more closely, but given that users can upgrade
their simulators I'm less worried about it.
There are two merge conflicts, both in build files. They're both a bit
clunky: arch/riscv/Kconfig is out of order (I have a script that's
supposed to keep them in order, I'll fix it) and lib/Makefile is out of
order (though GENERIC_LIB here doesn't mean quite what it does above).

Hi Linus,
Please, pull the following patches that fix many fall-through warnings
when building with Clang 12.0.0 and this[1] change reverted. Notice
that in order to enable -Wimplicit-fallthrough for Clang, such change[1]
is meant to be reverted at some point. So, these patches help to move
in that direction.
- powerpc: boot: include compiler_attributes.h (Nick Desaulniers)
- Revert "lib: Revert use of fallthrough pseudo-keyword in lib/" (Nick Desaulniers)
- powerpc: fix -Wimplicit-fallthrough (Nick Desaulniers)
- lib: Fix fall-through warnings for Clang (Gustavo A. R. Silva)

Commit af3b854492f351d1 ("mm/page_alloc.c: allow error injection")
introduced EI_ETYPE_TRUE, but did not extend
* lib/error-inject.c:error_type_string(), and
* kernel/fail_function.c:adjust_error_retval()
to accommodate for this change.
Handle EI_ETYPE_TRUE in both functions appropriately by
* returning "TRUE" in error_type_string(),
* adjusting the return value to true (1) in adjust_error_retval().
Furthermore, simplify the logic of handling EI_ETYPE_NULL in
adjust_error_retval().
