Enabling CONFIG_NETFILTER_FAMILY_BRIDGE causes the new element,
hooks_bridge[] to be added to netns_nf. Since the KMI is frozen
this could not be added.
The only instantiation of struct netns_nf is as an embedded field
of struct net. So instead of adding the field to struct netns_nf,
a new "struct ext_net" is added that contains struct net and
the new hooks_bridge[] field. An accessor function,
get_nf_hooks_bridge() is added to get a pointer to the new
field.
There is a global init_net of type struct net which must be special
cased since it is not a member of a struct ext_net. All other
instances of struct net are allocated via net_alloc() which now
allocates a struct ext_net.
Since CONFIG_NETFILTER_FAMILY_BRIDGE is a hidden config that is
needed for vendor modules, it is enabled via init/Kconfig.gki.
Bug: 316040984
Fixes: 0145780bfc78 ("fix KASAN-related kernel crash by KMI W/A for NETFILTER_FAMILY_BRIDGE")

commit 5b93a83649c7cba3a15eb7e8959b250841acb1b1 upstream.
Move poking_init() up a bunch; specifically move it right after
mm_init() which is right before ftrace_init().
This will allow simplifying ftrace text poking which currently has
a bunch of exceptions for early boot.

commit 9df9d2f0471b4c4702670380b8d8a45b40b23a7d upstream
X86 is reworking the boot process so that initializations which are not
required during early boot can be moved into the late boot process and out
of the fragile and restricted initial boot phase.
arch_cpu_finalize_init() is the obvious place to do such initializations,
but arch_cpu_finalize_init() is invoked too late in start_kernel() e.g. for
initializing the FPU completely. fork_init() requires that the FPU is
initialized as the size of task_struct on X86 depends on the size of the
required FPU register buffer.
Fortunately none of the init calls between calibrate_delay() and
arch_cpu_finalize_init() is relevant for the functionality of
arch_cpu_finalize_init().
Invoke it right after calibrate_delay() where everything which is relevant
for arch_cpu_finalize_init() has been set up already.
No functional change intended.

commit 7725acaa4f0c04fbefb0e0d342635b967bb7d414 upstream
check_bugs() has become a dumping ground for all sorts of activities to
finalize the CPU initialization before running the rest of the init code.
Most are empty, a few do actual bug checks, some do alternative patching
and some cobble a CPU advertisement string together....
Aside of that the current implementation requires duplicated function
declaration and mostly empty header files for them.
Provide a new function arch_cpu_finalize_init(). Provide a generic
declaration if CONFIG_ARCH_HAS_CPU_FINALIZE_INIT is selected and a stub
inline otherwise.
This requires a temporary #ifdef in start_kernel() which will be removed
along with check_bugs() once the architectures are converted over.

commit 0da6e5fd6c3726723e275603426e09178940dace upstream.
We started disabling '-Warray-bounds' for gcc-12 originally on s390,
because it resulted in some warnings that weren't realistically fixable
(commit 8b202ee218: "s390: disable -Warray-bounds").
That s390-specific issue was then found to be less common elsewhere, but
generic (see f0be87c42c: "gcc-12: disable '-Warray-bounds' universally
for now"), and then later expanded the version check was expanded to
gcc-11 (5a41237ad1d4: "gcc: disable -Warray-bounds for gcc-11 too").
And it turns out that I was much too optimistic in thinking that it's
all going to go away, and here we are with gcc-13 showing all the same
issues. So instead of expanding this one version at a time, let's just
disable it for gcc-11+, and put an end limit to it only when we actually
find a solution.
Yes, I'm sure some of this is because the kernel just does odd things
(like our "container_of()" use, but also knowingly playing games with
things like linker tables and array layouts).
And yes, some of the warnings are likely signs of real bugs, but when
there are hundreds of false positives, that doesn't really help.
Oh well.

commit 5a41237ad1d4b62008f93163af1d9b1da90729d8 upstream.
We had already disabled this warning for gcc-12 due to bugs in the value
range analysis, but it turns out we end up having some similar problems
with gcc-11.3 too, so let's disable it there too.
Older gcc versions end up being increasingly less relevant, and
hopefully clang and newer version of gcc (ie gcc-13) end up working
reliably enough that we still get the build coverage even when we
disable this for some versions.

In certain audio use cases, scheduling RT threads on cores that
are handling softirqs can lead to glitches. Prevent this
behavior in cases where the softirq is likely to take a long
time. To avoid unnecessary migrations, the old behavior is
preserved for RCU, SCHED and TIMER irqs which are expected to be
relatively quick.
This patch reworks and combines two related changes originally

v2:
* Reformatted Kconfig entry to match coding style
(Reported-by: Randy Dunlap <rdunlap@infradead.org>)
* Made rt_task_fits_capacity_and_may_preempt static to
avoid warnings (Reported-by: kernel test robot <lkp@intel.com>)
* Rework to use preempt_count and drop kconfig dependency on ARM64
v3:
* Use introduced __cpu_softirq_pending() to avoid s390 build
issues (Reported-by: kernel test robot <lkp@intel.com>)
v4:
* Drop TASKLET_SOFTIRQ from LONG_SOFTIRQS (suggested by Qais)
* Depend on !PREEMPT_RT (Suggested by Qais)
* Larger simplification of logic (suggested by Qais)
* Rework LONG_SOFTIRQS to use BIT() macros
* Rename task_may_preempt() to cpu_busy_with_softirqs()
v5:
* Conditionalize active_softirqs handling (suggested by Alexander
Gordeev <agordeev@linux.ibm.com>)
* Reorder rt_task_fits_cpu to have the "fast" function first
(Suggested by Alexander Gordeev <agordeev@linux.ibm.com>)
* Fix bug I introduced in v2 condensing
task_thread_info(task)->preempt_count to preempt_count()
(Reported-by: Alexander Gordeev <agordeev@linux.ibm.com>)
* Tweak comment discription to remove the vauge "slow"
descriptor of softirqs being run by ksoftirqd
(Suggested by Alexander Gordeev <agordeev@linux.ibm.com>)
* Switch to using CONFIG_RT_SOFTIRQ_AWARE_SCHED (suggested by
Joel Fernandes <joel@joelfernandes.org>)
* Simplify cpu_busy_with_softirqs() logic as pointed out by
Alexander Gordeev <agordeev@linux.ibm.com>
* Switch to using IS_ENABLED rather then defining my own macro
(suggsted by Joel Fernandes <joel@joelfernandes.org>)
When using dash as /bin/sh, the CC_HAS_ASM_GOTO_TIED_OUTPUT test fails
with a syntax error which is not the one we are looking for:
<stdin>: In function ‘foo’:
<stdin>:1:29: warning: missing terminating " character

<stdin>:2:5: error: expected ‘:’ before ‘+’ token
<stdin>:2:7: warning: missing terminating " character

<stdin>:2:5: error: expected declaration or statement at end of input
Removing '\n' solves this.

Commit 3c07bfce92a5 ("proc: make config PROC_CHILDREN depend on PROC_FS")
make config PROC_CHILDREN depend on PROC_FS.
When CONFIG_PROC_FS is not set and CONFIG_CHECKPOINT_RESTORE=y,
make menuconfig screams like this:
WARNING: unmet direct dependencies detected for PROC_CHILDREN
Depends on [n]: PROC_FS [=n]
Selected by [y]:
- CHECKPOINT_RESTORE [=y]
CHECKPOINT_RESTORE would select PROC_CHILDREN which depends on PROC_FS,
so add depends on PROC_FS to CHECKPOINT_RESTORE to fix this.

Pull random number generator updates from Jason Donenfeld:
- Huawei reported that when they updated their kernel from 4.4 to
something much newer, some userspace code they had broke, the culprit
being the accidental removal of O_NONBLOCK from /dev/random way back
in 5.6. It's been gone for over 2 years now and this is the first
we've heard of it, but userspace breakage is userspace breakage, so
O_NONBLOCK is now back.
- Use randomness from hardware RNGs much more often during early boot,
at the same interval that crng reseeds are done, from Dominik.
- A semantic change in hardware RNG throttling, so that the hwrng
framework can properly feed random.c with randomness from hardware
RNGs that aren't specifically marked as creditable.
A related patch coming to you via Herbert's hwrng tree depends on
this one, not to compile, but just to function properly, so you may
want to merge this PULL before that one.
- A fix to clamp credited bits from the interrupts pool to the size of
the pool sample. This is mainly just a theoretical fix, as it'd be
pretty hard to exceed it in practice.
- Oracle reported that InfiniBand TCP latency regressed by around
10-15% after a change a few cycles ago made at the request of the RT
folks, in which we hoisted a somewhat rare operation (1 in 1024
times) out of the hard IRQ handler and into a workqueue, a pretty
common and boring pattern.
It turns out, though, that scheduling a worker from there has
overhead of its own, whereas scheduling a timer on that same CPU for
the next jiffy amortizes better and doesn't incur the same overhead.
I also eliminated a cache miss by moving the work_struct (and
subsequently, the timer_list) to below a critical cache line, so that
the more critical members that are accessed on every hard IRQ aren't
split between two cache lines.
- The boot-time initialization of the RNG has been split into two
approximate phases: what we can accomplish before timekeeping is
possible and what we can accomplish after.
This winds up being useful so that we can use RDRAND to seed the RNG
before CONFIG_SLAB_FREELIST_RANDOM=y systems initialize slabs, in
addition to other early uses of randomness. The effect is that
systems with RDRAND (or a bootloader seed) will never see any
warnings at all when setting CONFIG_WARN_ALL_UNSEEDED_RANDOM=y. And
kfence benefits from getting a better seed of its own.
- Small systems without much entropy sometimes wind up putting some
truncated serial number read from flash into hostname, so contribute
utsname changes to the RNG, without crediting.
- Add smaller batches to serve requests for smaller integers, and make
use of them when people ask for random numbers bounded by a given
compile-time constant. This has positive effects all over the tree,
most notably in networking and kfence.
- The original jitter algorithm intended (I believe) to schedule the
timer for the next jiffy, not the next-next jiffy, yet it used
mod_timer(jiffies + 1), which will fire on the next-next jiffy,
instead of what I believe was intended, mod_timer(jiffies), which
will fire on the next jiffy. So fix that.
- Fix a comment typo, from William.

Add one CONFIG to control removing the macros or not. On some platform,
configureing out the macros removes the associated members from the
structs, this reduces the object size of the slabs related with the
structs, therefore reduces the total slab memory consumption of system.
Besides, this also reduces vmlinux size a bit, therefore the total
kernel memory size increses a bit.
The macros are ANDROID_KABI_RESERVE, ANDROID_VENDOR_DATA,
ANDROID_VENDOR_DATA_ARRAY, ANDROID_OEM_DATA, ANDROID_OEM_DATA_ARRAY.

The full RNG initialization relies on some timestamps, made possible
with initialization functions like time_init() and timekeeping_init().
However, these are only available rather late in initialization.
Meanwhile, other things, such as memory allocator functions, make use of
the RNG much earlier.
So split RNG initialization into two phases. We can provide arch
randomness very early on, and then later, after timekeeping and such are
available, initialize the rest.
This ensures that, for example, slabs are properly randomized if RDRAND
is available. Without this, CONFIG_SLAB_FREELIST_RANDOM=y loses a degree
of its security, because its random seed is potentially deterministic,
since it hasn't yet incorporated RDRAND. It also makes it possible to
use a better seed in kfence, which currently relies on only the cycle
counter.
Another positive consequence is that on systems with RDRAND, running
with CONFIG_WARN_ALL_UNSEEDED_RANDOM=y results in no warnings at all.
One subtle side effect of this change is that on systems with no RDRAND,
RDTSC is now only queried by random_init() once, committing the moment
of the function call, instead of multiple times as before. This is
intentional, as the multiple RDTSCs in a loop before weren't
accomplishing very much, with jitter being better provided by
try_to_generate_entropy(). Plus, filling blocks with RDTSC is still
being done in extract_entropy(), which is necessarily called before
random bytes are served anyway.

Now that UTS_VERSION was separated out, this header can be generated

Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
Kbuild builds init/built-in.a twice; first during the ordinary
directory descending, second from scripts/link-vmlinux.sh.
We do this because UTS_VERSION contains the build version and the
timestamp. We cannot update it during the normal directory traversal
since we do not yet know if we need to update vmlinux. UTS_VERSION is
temporarily calculated, but omitted from the update check. Otherwise,
vmlinux would be rebuilt every time.
When Kbuild results in running link-vmlinux.sh, it increments the
version number in the .version file and takes the timestamp at that
time to really fix UTS_VERSION.
However, updating the same file twice is a footgun. To avoid nasty
timestamp issues, all build artifacts that depend on init/built-in.a
are atomically generated in link-vmlinux.sh, where some of them do not
need rebuilding.
To fix this issue, this commit changes as follows:
[1] Split UTS_VERSION out to include/generated/utsversion.h from
include/generated/compile.h
include/generated/utsversion.h is generated just before the
vmlinux link. It is generated under include/generated/ because
some decompressors (s390, x86) use UTS_VERSION.
[2] Split init_uts_ns and linux_banner out to init/version-timestamp.c
from init/version.c
init_uts_ns and linux_banner contain UTS_VERSION. During the ordinary
directory descending, they are compiled with __weak and used to
determine if vmlinux needs relinking. Just before the vmlinux link,
they are compiled without __weak to embed the real version and
timestamp.

Patch series "Introducing the Maple Tree"
The maple tree is an RCU-safe range based B-tree designed to use modern
processor cache efficiently. There are a number of places in the kernel
that a non-overlapping range-based tree would be beneficial, especially
one with a simple interface. If you use an rbtree with other data
structures to improve performance or an interval tree to track
non-overlapping ranges, then this is for you.
The tree has a branching factor of 10 for non-leaf nodes and 16 for leaf
nodes. With the increased branching factor, it is significantly shorter
than the rbtree so it has fewer cache misses. The removal of the linked
list between subsequent entries also reduces the cache misses and the need
to pull in the previous and next VMA during many tree alterations.
The first user that is covered in this patch set is the vm_area_struct,
where three data structures are replaced by the maple tree: the augmented
rbtree, the vma cache, and the linked list of VMAs in the mm_struct. The
long term goal is to reduce or remove the mmap_lock contention.
The plan is to get to the point where we use the maple tree in RCU mode.
Readers will not block for writers. A single write operation will be
allowed at a time. A reader re-walks if stale data is encountered. VMAs
would be RCU enabled and this mode would be entered once multiple tasks
are using the mm_struct.
Davidlor said
: Yes I like the maple tree, and at this stage I don't think we can ask for
: more from this series wrt the MM - albeit there seems to still be some
: folks reporting breakage. Fundamentally I see Liam's work to (re)move
: complexity out of the MM (not to say that the actual maple tree is not
: complex) by consolidating the three complimentary data structures very
: much worth it considering performance does not take a hit. This was very
: much a turn off with the range locking approach, which worst case scenario

: mentioned, RCU opens up a lot of nice performance opportunities, and in
: addition academia[1] has shown outstanding scalability of address spaces
: with the foundation of replacing the locked rbtree with RCU aware trees.
A similar work has been discovered in the academic press
https://pdos.csail.mit.edu/papers/rcuvm:asplos12.pdf
Sheer coincidence. We designed our tree with the intention of solving the
hardest problem first. Upon settling on a b-tree variant and a rough
outline, we researched ranged based b-trees and RCU b-trees and did find
that article. So it was nice to find reassurances that we were on the
right path, but our design choice of using ranges made that paper unusable
for us.
This patch (of 70):
The maple tree is an RCU-safe range based B-tree designed to use modern
processor cache efficiently. There are a number of places in the kernel
that a non-overlapping range-based tree would be beneficial, especially
one with a simple interface. If you use an rbtree with other data
structures to improve performance or an interval tree to track
non-overlapping ranges, then this is for you.
The tree has a branching factor of 10 for non-leaf nodes and 16 for leaf
nodes. With the increased branching factor, it is significantly shorter
than the rbtree so it has fewer cache misses. The removal of the linked
list between subsequent entries also reduces the cache misses and the need
to pull in the previous and next VMA during many tree alterations.
The first user that is covered in this patch set is the vm_area_struct,
where three data structures are replaced by the maple tree: the augmented
rbtree, the vma cache, and the linked list of VMAs in the mm_struct. The
long term goal is to reduce or remove the mmap_lock contention.
The plan is to get to the point where we use the maple tree in RCU mode.
Readers will not block for writers. A single write operation will be
allowed at a time. A reader re-walks if stale data is encountered. VMAs
would be RCU enabled and this mode would be entered once multiple tasks
are using the mm_struct.
There is additional BUG_ON() calls added within the tree, most of which
are in debug code. These will be replaced with a WARN_ON() call in the
future. There is also additional BUG_ON() calls within the code which
will also be reduced in number at a later date. These exist to catch
things such as out-of-range accesses which would crash anyways.

REGMAP_SPMI is a hidden symbol normally selected by other SPMI drivers,
but it wasn't built-in to GKI like other REGMAP APIs so vendors had to
build it downstream.
This is a small amount of code and can be modularized later.
For allmodconfig, select SPMI via Kconfig.gki instead of gki_defconfig,
because otherwise allmodconfig will build SPMI=m and REGMAP_SPMI=y,
which is not allowed.

As my_inptr is only used in __init function unpack_to_rootfs(), mark it as
__initdata to allow it be freed after boot.
