ANDROID: qki: Add consolidate config
Add a "consolidate" defconfig fragment to enable further debug options of the GKI kernel. The "consolidate" name has a storied history, but it's effectively a "debug" kernel. The options enabled in the consolidate.fragment have been found to have a good balance of additional debug features versus performance impact. For instance, SLUB_DEBUG is not enabled due to large performance impact.

ANDROID: Improve OWNERS file definitions
- Extend subdirectory expressions to also include recursively
- Combine expressions with common owners
- Minor cleanups
Note, the way expressions are evaluated in the plugin (as of now and
for compatibility with the `find-owners` plugin), means we match
slightly more than expected, even with just the single asterisk.
As expressions like `net*` are implicitly treated like `{**/,}net*`,
we would not only match net_something.h and net_filter/header.h, but
also (unexpectedly) platform/net_something.h.
This change does not make things better in this regards, but for all the
above mentioned points, this is an improvement.

ANDROID: Sync ext4 casefolded encryption with patches going upstream
This brings the ext4 casefolded encryption implementation in line with the patches that have gone upstream. This is equivalent to reverting "ANDROID-ext4-Handle-casefolding-with-encryption.patch" "ANDROID-ext4-Optimize-match-for-casefolded-encrypted-dirs.patch" and applying the equivalent upstream patches. This now advertises the feature in sysfs under /sys/fs/ext4/features/encrypted_casefold Change-Id: Ia8f437c5f137f16edf0a90c090a226d10c9e5660 Bug: 161184936 Signed-off-by: Daniel Rosenberg <drosen@google.com> |

ANDROID: vendor_hooks: set debugging data when rt_mutex is working
We already applied the 'vendor hook' for Dtask Debugging Information in below issue. (https://issuetracker.google.com/issues/162776704) There are vendor hook call in mutex and rw_semaphore, but not for rt_mutex Please refer to description in details as below, 1. Description This feature writes rt mutex lock waiting information on the task_struct structure. We can check mutex information and mutex owner through the kernel log and custom analysis tools. Like the previous feature in mutex and rw semaphore, added data can be checked by ramdump analysis. 2. Vendor Hook Position 1) VENDOR_DATA - struct task_struct in sched.h VENDOR_DATA_ARRAY(2) [0] : type // RTmutex (Mutex, Rwsem, ...) [1] : pointer // address of lock 2) VENDOR_HOOKs - __rt_mutex_slowlock() in kernel/locking/rtmutex.c 3. Example - SysRq-w in kernel log ...

Scheduler updates for this cycle are:
- Clean up SCHED_DEBUG: move the decades old mess of sysctl, procfs and debugfs interfaces
to a unified debugfs interface.
- Signals: Allow caching one sigqueue object per task, to improve performance & latencies.
- Improve newidle_balance() irq-off latencies on systems with a large number of CPU cgroups.
- Improve energy-aware scheduling
- Improve the PELT metrics for certain workloads
- Reintroduce select_idle_smt() to improve load-balancing locality - but without the previous
regressions
- Add 'scheduler latency debugging': warn after long periods of pending need_resched. This
is an opt-in feature that requires the enabling of the LATENCY_WARN scheduler feature,
or the use of the resched_latency_warn_ms=xx boot parameter.
- CPU hotplug fixes for HP-rollback, and for the 'fail' interface. Fix remaining
balance_push() vs. hotplug holes/races
- PSI fixes, plus allow /proc/pressure/ files to be written by CAP_SYS_RESOURCE tasks as well
- Fix/improve various load-balancing corner cases vs. capacity margins
- Fix sched topology on systems with NUMA diameter of 3 or above
- Fix PF_KTHREAD vs to_kthread() race
- Minor rseq optimizations
- Misc cleanups, optimizations, fixes and smaller updates

Perf events changes in this cycle were:
- Improve Intel uncore PMU support:
- Parse uncore 'discovery tables' - a new hardware capability enumeration method
introduced on the latest Intel platforms. This table is in a well-defined PCI
namespace location and is read via MMIO. It is organized in an rbtree.
These uncore tables will allow the discovery of standard counter blocks, but
fancier counters still need to be enumerated explicitly.
- Add Alder Lake support
- Improve IIO stacks to PMON mapping support on Skylake servers
- Add Intel Alder Lake PMU support - which requires the introduction of 'hybrid' CPUs
and PMUs. Alder Lake is a mix of Golden Cove ('big') and Gracemont ('small' - Atom derived)
cores.
The CPU-side feature set is entirely symmetrical - but on the PMU side there's
core type dependent PMU functionality.
- Reduce data loss with CPU level hardware tracing on Intel PT / AUX profiling, by
fixing the AUX allocation watermark logic.
- Improve ring buffer allocation on NUMA systems
- Put 'struct perf_event' into their separate kmem_cache pool
- Add support for synchronous signals for select perf events. The immediate motivation
is to support low-overhead sampling-based race detection for user-space code. The
feature consists of the following main changes:
- Add thread-only event inheritance via perf_event_attr::inherit_thread, which limits
inheritance of events to CLONE_THREAD.
- Add the ability for events to not leak through exec(), via perf_event_attr::remove_on_exec.
- Allow the generation of SIGTRAP via perf_event_attr::sigtrap, extend siginfo with an u64
::si_perf, and add the breakpoint information to ::si_addr and ::si_perf if the event is
PERF_TYPE_BREAKPOINT.
The siginfo support is adequate for breakpoints right now - but the new field can be used
to introduce support for other types of metadata passed over siginfo as well.
- Misc fixes, cleanups and smaller updates.

linux-kselftest-kunit-5.13-rc1
This KUnit update for Linux 5.13-rc1 consists of several fixes and
new feature to support failure from dynamic analysis tools such as
UBSAN and fake ops for testing.
- a fake ops struct for testing a "free" function to complain if it
was called with an invalid argument, or caught a double-free. Most
return void and have no normal means of signalling failure
(e.g. super_operations, iommu_ops, etc.).

kgdb patches for 5.13
Exclusively tidy ups this cycle. Most of them are thanks to Sumit Garg and, as it happens, the clean ups do result in a slight increase in the line count. This is due to registering kdb commands using data structures rather than function calls which, in turn, simplifies the memory management during command registration. In addition to changes to command registration we also have some dead code removal, a clearer implementation of environment variable handling and a typo fix.

s390 updates for 5.13 merge window
- fix buffer size for in-kernel disassembler for ebpf programs. - fix two memory leaks in zcrypt driver. - expose PCI device UID as index, including an indicator if the uid is unique. - remove some oprofile leftovers. - improve stack unwinder tests. - don't use gcc atomic builtins anymore, just like all other architectures. Even though I'm sure the current code is ok, I totally dislike that s390 is the only architecture being special here; especially considering that there was a lengthly discussion about this topic and the outcome was not to use the builtins. Therefore open-code atomic ops again with inline assembly and switch to gcc builtins as soon as other architectures are doing. - couple of other changes to atomic and cmpxchg, and use atomic-instrumented.h for KASAN. - separate zbus creation, registration, and scanning in our PCI code which allows for cleaner and easier handling. - a rather large change to the vfio-ap code to fix circular locking dependencies when updating crypto masks. - move QAOB handling from qdio layer down to drivers. - add CRW inject facility to common I/O layer. This adds debugs files which allow to generate artificial events from user space for testing purposes. - increase SCLP console line length from 80 to 320 characters to avoid odd wrapped lines. - add protected virtualization guest and host indication files, which indicate either that a guest is running in pv mode or if the hypervisor is capable of starting pv guests. - various other small fixes and improvements all over the place. -----BEGIN PGP SIGNATURE----- iQIyBAABCAAdFiEECMNfWEw3SLnmiLkZIg7DeRspbsIFAmCICNwACgkQIg7DeRsp bsJgSQ/0Cn3KTymF8SJ7tXLpYBNHmZBL1sQ284pPNYmqluwephUaX643f/48RR5y rlbaewyHCbYyR+gwkUykuUQm/d+iwihip/uFmyEktr9JutOOS1RQKd8ujeyE2BUb aaDyE0J5VFYdd/ZA92n9FhkuNDOMZRFAK1SOfifT9jNWCl8iYz+pXV1Gx7LbJYVY KWfJ9D/zgzLoOTWhj4jWu8LutfLEqK+hq5nqxBII8APCV/QDYnjkwpwW01LoMtOv eHhtSz0JboFRk0FYf8oyR7AXQBz76+Ru3aivJNL7sr1S3N2yMSzNQbk/ATVBLER9 VMQX2TfGGT/Ln3P4rYEoP2vGITRn765wg4KWNB2u3pY2try12G39fmjzOwVfbxQw BDAcLwxU7Tw0vJY+yI6ZWkPDXcs+uAWQwNiYoMtfUPfMYLEpLFffbWGwdZPKZRrH fy4e5ZFuavZsZr8Zeu4WYILJZoDnvhbs59gPzaLBPKosR0ZGNi8q6bnztnqnrYhi Oirt6aPOOyEoN/IT2bO1sDhIzIpCorIwCMZTRIQzerFRcjJgy0xHM9MRYRLMj6iW xltgWNt01SbTm6pbimwMUnjN5AdMTbHlTSzD8G34eWO21cVgHGpndbcT/M3uemyy Wf034Er2eFqlhXyhiAYTnNhVGbd+YMido7eo/CbGvqCxNvmKbA== =e+mh -----END PGP SIGNATURE----- Merge tag 's390-5.13-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux Pull s390 updates from Heiko Carstens: - fix buffer size for in-kernel disassembler for ebpf programs. - fix two memory leaks in zcrypt driver. - expose PCI device UID as index, including an indicator if the uid is unique. - remove some oprofile leftovers. - improve stack unwinder tests. - don't use gcc atomic builtins anymore, just like all other architectures.

Fix misc new gcc warnings
It seems like Fedora 34 ends up enabling a few new gcc warnings, notably "-Wstringop-overread" and "-Warray-parameter". Both of them cause what seem to be valid warnings in the kernel, where we have array size mismatches in function arguments (that are no longer just silently converted to a pointer to element, but actually checked). This fixes most of the trivial ones, by making the function declaration match the function definition, and in the case of intel_pm.c, removing the over-specified array size from the argument declaration. At least one 'stringop-overread' warning remains in the i915 driver, but that one doesn't have the same obvious trivial fix, and may or may not actually be indicative of a bug. [ It was a mistake to upgrade one of my machines to Fedora 34 while being busy with the merge window, but if this is the extent of the compiler upgrade problems, things are better than usual - Linus ] Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |

Pull AFS updates from David Howells:
"Use the new netfs lib.
Begin the process of overhauling the use of the fscache API by AFS and
the introduction of support for features such as Transparent Huge
Pages (THPs).
- Add some support for THPs, including using core VM helper functions
to find details of pages.
- Use the ITER_XARRAY I/O iterator to mediate access to the pagecache
as this handles THPs and doesn't require allocation of large bvec
arrays.
- Delegate address_space read/pre-write I/O methods for AFS to the
netfs helper library. A method is provided to the library that
allows it to issue a read against the server.
This includes a change in use for PG_fscache (it now indicates a
DIO write in progress from the marked page), so a number of waits
need to be deployed for it.
- Split the core AFS writeback function to make it easier to modify
in future patches to handle writing to the cache. [This might
feasibly make more sense moved out into my fscache-iter branch].
I've tested these with "xfstests -g quick" against an AFS volume
(xfstests needs patching to make it work). With this, AFS without a
cache passes all expected xfstests; with a cache, there's an extra
failure, but that's also there before these patches. Fixing that
probably requires a greater overhaul (as can be found on my
fscache-iter branch, but that's for a later time).
Thanks should go to Marc Dionne and Jeff Altman of AuriStor for
exercising the patches in their test farm also"

Merge tag 'netfs-lib-20210426' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs
Pull network filesystem helper library updates from David Howells:
"Here's a set of patches for 5.13 to begin the process of overhauling
the local caching API for network filesystems. This set consists of
two parts:
(1) Add a helper library to handle the new VM readahead interface.
This is intended to be used unconditionally by the filesystem
(whether or not caching is enabled) and provides a common
framework for doing caching, transparent huge pages and, in the
future, possibly fscrypt and read bandwidth maximisation. It also
allows the netfs and the cache to align, expand and slice up a
read request from the VM in various ways; the netfs need only
provide a function to read a stretch of data to the pagecache and
the helper takes care of the rest.
(2) Add an alternative fscache/cachfiles I/O API that uses the kiocb
facility to do async DIO to transfer data to/from the netfs's
pages, rather than using readpage with wait queue snooping on one
side and vfs_write() on the other. It also uses less memory, since
it doesn't do buffered I/O on the backing file.
Note that this uses SEEK_HOLE/SEEK_DATA to locate the data
available to be read from the cache. Whilst this is an improvement
from the bmap interface, it still has a problem with regard to a
modern extent-based filesystem inserting or removing bridging
blocks of zeros. Fixing that requires a much greater overhaul.
This is a step towards overhauling the fscache API. The change is
opt-in on the part of the network filesystem. A netfs should not try
to mix the old and the new API because of conflicting ways of handling
pages and the PG_fscache page flag and because it would be mixing DIO
with buffered I/O. Further, the helper library can't be used with the
old API.
This does not change any of the fscache cookie handling APIs or the
way invalidation is done at this time.
In the near term, I intend to deprecate and remove the old I/O API
(fscache_allocate_page{,s}(), fscache_read_or_alloc_page{,s}(),
fscache_write_page() and fscache_uncache_page()) and eventually
replace most of fscache/cachefiles with something simpler and easier
to follow.
This patchset contains the following parts:
- Some helper patches, including provision of an ITER_XARRAY iov
iterator and a function to do readahead expansion.
- Patches to add the netfs helper library.
- A patch to add the fscache/cachefiles kiocb API.
- A pair of patches to fix some review issues in the ITER_XARRAY and
read helpers as spotted by Al and Willy.
Jeff Layton has patches to add support in Ceph for this that he
intends for this merge window. I have a set of patches to support AFS
that I will post a separate pull request for.
With this, AFS without a cache passes all expected xfstests; with a
cache, there's an extra failure, but that's also there before these
patches. Fixing that probably requires a greater overhaul. Ceph also
passes the expected tests.
I also have patches in a separate branch to tidy up the handling of
PG_fscache/PG_private_2 and their contribution to page refcounting in
the core kernel here, but I haven't included them in this set and will
route them separately"

CFI support for x86 is still under development, but is pretty close. There are a handful of corner cases on x86 that need some improvements to Clang and objtool, but otherwise works well.

cfg80211: fix locking in netlink owner interface destruction
Harald Arnesen reported [1] a deadlock at reboot time, and after
he captured a stack trace a picture developed of what's going on:
The distribution he's using is using iwd (not wpa_supplicant) to
manage wireless. iwd will usually use the "socket owner" option
when it creates new interfaces, so that they're automatically
destroyed when it quits (unexpectedly or otherwise). This is also
done by wpa_supplicant, but it doesn't do it for the normal one,
only for additional ones, which is different with iwd.
Anyway, during shutdown, iwd quits while the netdev is still UP,
i.e. IFF_UP is set. This causes the stack trace that Linus so
nicely transcribed from the pictures:
cfg80211_destroy_iface_wk() takes wiphy_lock
-> cfg80211_destroy_ifaces()
->ieee80211_del_iface
->ieeee80211_if_remove
->cfg80211_unregister_wdev
->unregister_netdevice_queue
->dev_close_many
->__dev_close_many
->raw_notifier_call_chain
->cfg80211_netdev_notifier_call
and that last call tries to take wiphy_lock again.
