2020-07-10dt-bindings: fix simple-framebuffer exampleSam Ravnborg
Now that dt-extract-example gained support for using root nodes in examples, update the example for the simple-frambuffer binding to use it. This gives us a better example and kill a long standing warning: simple-framebuffer.example.dts:23.16-39.11: Warning (chosen_node_is_root): /example-0/chosen: chosen node must be at root node Note: To get the update dt-extract-example execute: pip3 install git+https://github.com/devicetree-org/dt-schema.git@master --upgrade v2: - fix spelling of framebuffer (Geert) - drop stdout-path (Rob) Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Reviewed-by: Rob Herring <robh@kernel.org> Cc: Geert Uytterhoeven <geert@linux-m68k.org> Cc: Hans de Goede <hdegoede@redhat.com> Cc: David Airlie <airlied@linux.ie> Cc: Daniel Vetter <daniel@ffwll.ch> Cc: Bartlomiej Zolnierkiewicz <b.zolnierkie@samsung.com> Cc: linux-fbdev@vger.kernel.org Link: https://patchwork.freedesktop.org/patch/msgid/20200704143544.789345-2-sam@ravnborg.org

2020-06-15powerpc/papr_scm: Fetch nvdimm health information from PHYPVaibhav Jain
Implement support for fetching nvdimm health information via H_SCM_HEALTH hcall as documented in Ref[1]. The hcall returns a pair of 64-bit bitmap, bitwise-and of which is then stored in 'struct papr_scm_priv' and subsequently partially exposed to user-space via newly introduced dimm specific attribute 'papr/flags'. Since the hcall is costly, the health information is cached and only re-queried, 60s after the previous successful hcall. The patch also adds a documentation text describing flags reported by the the new sysfs attribute 'papr/flags' is also introduced at Documentation/ABI/testing/sysfs-bus-papr-pmem.

sve.rst describes a flag PR_SVE_SET_VL_INHERIT for the PR_SVE_SET_VL prctl, but there is no flag of this name. The flag is shared between the _GET and _SET calls, so the _SET prefix was dropped, giving the name PR_SVE_VL_INHERIT in the headers. Fix it.

git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs Pull notification queue from David Howells: "This adds a general notification queue concept and adds an event source for keys/keyrings, such as linking and unlinking keys and changing their attributes. Thanks to Debarshi Ray, we do have a pull request to use this to fix a problem with gnome-online-accounts - as mentioned last time: https://gitlab.gnome.org/GNOME/gnome-online-accounts/merge_requests/47 Without this, g-o-a has to constantly poll a keyring-based kerberos cache to find out if kinit has changed anything. [ There are other notification pending: mount/sb fsinfo notifications for libmount that Karel Zak and Ian Kent have been working on, and Christian Brauner would like to use them in lxc, but let's see how this one works first ] LSM hooks are included: - A set of hooks are provided that allow an LSM to rule on whether or not a watch may be set. Each of these hooks takes a different "watched object" parameter, so they're not really shareable. The LSM should use current's credentials. [Wanted by SELinux & Smack] - A hook is provided to allow an LSM to rule on whether or not a particular message may be posted to a particular queue. This is given the credentials from the event generator (which may be the system) and the watch setter. [Wanted by Smack] I've provided SELinux and Smack with implementations of some of these hooks. WHY === Key/keyring notifications are desirable because if you have your kerberos tickets in a file/directory, your Gnome desktop will monitor that using something like fanotify and tell you if your credentials cache changes. However, we also have the ability to cache your kerberos tickets in the session, user or persistent keyring so that it isn't left around on disk across a reboot or logout. Keyrings, however, cannot currently be monitored asynchronously, so the desktop has to poll for it - not so good on a laptop. This facility will allow the desktop to avoid the need to poll. DESIGN DECISIONS ================ - The notification queue is built on top of a standard pipe. Messages are effectively spliced in. The pipe is opened with a special flag: pipe2(fds, O_NOTIFICATION_PIPE); The special flag has the same value as O_EXCL (which doesn't seem like it will ever be applicable in this context)[?]. It is given up front to make it a lot easier to prohibit splice&co from accessing the pipe. [?] Should this be done some other way? I'd rather not use up a new O_* flag if I can avoid it - should I add a pipe3() system call instead? The pipe is then configured:: ioctl(fds[1], IOC_WATCH_QUEUE_SET_SIZE, queue_depth); ioctl(fds[1], IOC_WATCH_QUEUE_SET_FILTER, &filter); Messages are then read out of the pipe using read(). - It should be possible to allow write() to insert data into the notification pipes too, but this is currently disabled as the kernel has to be able to insert messages into the pipe *without* holding pipe->mutex and the code to make this work needs careful auditing. - sendfile(), splice() and vmsplice() are disabled on notification pipes because of the pipe->mutex issue and also because they sometimes want to revert what they just did - but one or more notification messages might've been interleaved in the ring. - The kernel inserts messages with the wait queue spinlock held. This means that pipe_read() and pipe_write() have to take the spinlock to update the queue pointers. - Records in the buffer are binary, typed and have a length so that they can be of varying size. This allows multiple heterogeneous sources to share a common buffer; there are 16 million types available, of which I've used just a few, so there is scope for others to be used. Tags may be specified when a watchpoint is created to help distinguish the sources. - Records are filterable as types have up to 256 subtypes that can be individually filtered. Other filtration is also available. - Notification pipes don't interfere with each other; each may be bound to a different set of watches. Any particular notification will be copied to all the queues that are currently watching for it - and only those that are watching for it. - When recording a notification, the kernel will not sleep, but will rather mark a queue as having lost a message if there's insufficient space. read() will fabricate a loss notification message at an appropriate point later. - The notification pipe is created and then watchpoints are attached to it, using one of: keyctl_watch_key(KEY_SPEC_SESSION_KEYRING, fds[1], 0x01); watch_mount(AT_FDCWD, "/", 0, fd, 0x02); watch_sb(AT_FDCWD, "/mnt", 0, fd, 0x03); where in both cases, fd indicates the queue and the number after is a tag between 0 and 255. - Watches are removed if either the notification pipe is destroyed or the watched object is destroyed. In the latter case, a message will be generated indicating the enforced watch removal. Things I want to avoid: - Introducing features that make the core VFS dependent on the network stack or networking namespaces (ie. usage of netlink). - Dumping all this stuff into dmesg and having a daemon that sits there parsing the output and distributing it as this then puts the responsibility for security into userspace and makes handling namespaces tricky. Further, dmesg might not exist or might be inaccessible inside a container. - Letting users see events they shouldn't be able to see. TESTING AND MANPAGES ==================== - The keyutils tree has a pipe-watch branch that has keyctl commands for making use of notifications. Proposed manual pages can also be found on this branch, though a couple of them really need to go to the main manpages repository instead. If the kernel supports the watching of keys, then running "make test" on that branch will cause the testing infrastructure to spawn a monitoring process on the side that monitors a notifications pipe for all the key/keyring changes induced by the tests and they'll all be checked off to make sure they happened. https://git.kernel.org/pub/scm/linux/kernel/git/dhowells/keyutils.git/log/?h=pipe-watch - A test program is provided (samples/watch_queue/watch_test) that can be used to monitor for keyrings, mount and superblock events.

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull the Kernel Concurrency Sanitizer from Thomas Gleixner: "The Kernel Concurrency Sanitizer (KCSAN) is a dynamic race detector, which relies on compile-time instrumentation, and uses a watchpoint-based sampling approach to detect races. The feature was under development for quite some time and has already found legitimate bugs. Unfortunately it comes with a limitation, which was only understood late in the development cycle: It requires an up to date CLANG-11 compiler CLANG-11 is not yet released (scheduled for June), but it's the only compiler today which handles the kernel requirements and especially the annotations of functions to exclude them from KCSAN instrumentation correctly. These annotations really need to work so that low level entry code and especially int3 text poke handling can be completely isolated. A detailed discussion of the requirements and compiler issues can be found here: https://lore.kernel.org/lkml/CANpmjNMTsY_8241bS7=XAfqvZHFLrVEkv_uM4aDUWE_kh3Rvbw@mail.gmail.com/ We came to the conclusion that trying to work around compiler limitations and bugs again would end up in a major trainwreck, so requiring a working compiler seemed to be the best choice. For Continous Integration purposes the compiler restriction is manageable and that's where most xxSAN reports come from. For a change this limitation might make GCC people actually look at their bugs. Some issues with CSAN in GCC are 7 years old and one has been 'fixed' 3 years ago with a half baken solution which 'solved' the reported issue but not the underlying problem. The KCSAN developers also ponder to use a GCC plugin to become independent, but that's not something which will show up in a few days. Blocking KCSAN until wide spread compiler support is available is not a really good alternative because the continuous growth of lockless optimizations in the kernel demands proper tooling support" * tag 'locking-kcsan-2020-06-11' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (76 commits) compiler_types.h, kasan: Use __SANITIZE_ADDRESS__ instead of CONFIG_KASAN to decide inlining compiler.h: Move function attributes to compiler_types.h compiler.h: Avoid nested statement expression in data_race() compiler.h: Remove data_race() and unnecessary checks from {READ,WRITE}_ONCE() kcsan: Update Documentation to change supported compilers kcsan: Remove 'noinline' from __no_kcsan_or_inline kcsan: Pass option tsan-instrument-read-before-write to Clang kcsan: Support distinguishing volatile accesses kcsan: Restrict supported compilers kcsan: Avoid inserting __tsan_func_entry/exit if possible ubsan, kcsan: Don't combine sanitizer with kcov on clang objtool, kcsan: Add kcsan_disable_current() and kcsan_enable_current_nowarn() kcsan: Add __kcsan_{enable,disable}_current() variants checkpatch: Warn about data_race() without comment kcsan: Use GFP_ATOMIC under spin lock Improve KCSAN documentation a bit kcsan: Make reporting aware of KCSAN tests kcsan: Fix function matching in report kcsan: Change data_race() to no longer require marking racing accesses kcsan: Move kcsan_{disable,enable}_current() to kcsan-checks.h ...
2020-06-11lib/lzo: fix ambiguous encoding bug in lzo-rleDave Rodgman
In some rare cases, for input data over 32 KB, lzo-rle could encode two different inputs to the same compressed representation, so that decompression is then ambiguous (i.e. data may be corrupted - although zram is not affected because it operates over 4 KB pages). This modifies the compressor without changing the decompressor or the bitstream format, such that: - there is no change to how data produced by the old compressor is decompressed - an old decompressor will correctly decode data from the updated compressor - performance and compression ratio are not affected - we avoid introducing a new bitstream format In testing over 12.8M real-world files totalling 903 GB, three files were affected by this bug. I also constructed 37M semi-random 64 KB files totalling 2.27 TB, and saw no affected files. Finally I tested over files constructed to contain each of the ~1024 possible bad input sequences; for all of these cases, updated lzo-rle worked correctly. There is no significant impact to performance or compression ratio.

Another round of 'allOf' removals that came in this cycle. json-schema versions draft7 and earlier have a weird behavior in that any keywords combined with a '$ref' are ignored (silently). The correct form was to put a '$ref' under an 'allOf'. This behavior is now changed in the 2019-09 json-schema spec and '$ref' can be mixed with other keywords. The json-schema library doesn't yet support this, but the tooling now does a fixup for this and either way works. This has been a constant source of review comments, so let's change this treewide so everyone copies the simpler syntax. Signed-off-by: Rob Herring <robh@kernel.org>
