       "These add support for 'artificial' Energy Models in which power
        numbers for different entities may be in different scales, add support
        for some new hardware, fix bugs and clean up code in multiple places.
      
        Specifics:
      
         - Update the Energy Model support code to allow the Energy Model to
           be artificial, which means that the power values may not be on a
           uniform scale with other devices providing power information, and
           update the cpufreq_cooling and devfreq_cooling thermal drivers to
           support artificial Energy Models (Lukasz Luba).
      
         - Make DTPM check the Energy Model type (Lukasz Luba).

           PM-runtime counterparts (Jonathan Cameron).
      
         - Move symbol exports in the IIO chemical scd30 driver into the
           IIO_SCD30 namespace (Jonathan Cameron).

           driver and fix the riscv-sbi cpuidle driver to allow a genpd
           governor to be used (Ulf Hansson).
      
         - Fix cpufreq governor clean up code to avoid using kfree() directly
           to free kobject-based items (Kevin Hao).
      
         - Prepare cpufreq for powerpc's asm/prom.h cleanup (Christophe
           Leroy).
      
         - Make intel_pstate notify frequency invariance code when no_turbo is
           turned on and off (Chen Yu).

           Wysocki).
      
         - Avoid accessing half-initialized cpufreq policies from the show()
           and store() sysfs functions (Schspa Shi).
      
         - Rearrange cpufreq_offline() to make the calling convention for some
           driver callbacks consistent (Schspa Shi).

        digest based signatures, both based on policy.
      
        In addition, are two bug fixes:
      
         - avoid reading UEFI variables, which cause a page fault, on Apple
           Macs with T2 chips.
      
         - remove the original "ima" template Kconfig option to address a boot
           command line ordering issue.
      
        The rest is a mixture of code/documentation cleanup"

      Pull random number generator updates from Jason Donenfeld:
       "These updates continue to refine the work began in 5.17 and 5.18 of
        modernizing the RNG's crypto and streamlining and documenting its
        code.
      
        New for 5.19, the updates aim to improve entropy collection methods
        and make some initial decisions regarding the "premature next" problem
        and our threat model. The cloc utility now reports that random.c is
        931 lines of code and 466 lines of comments, not that basic metrics
        like that mean all that much, but at the very least it tells you that
        this is very much a manageable driver now.
      
        Here's a summary of the various updates:
      
         - The random_get_entropy() function now always returns something at
           least minimally useful. This is the primary entropy source in most
           collectors, which in the best case expands to something like RDTSC,
           but prior to this change, in the worst case it would just return 0,
           contributing nothing. For 5.19, additional architectures are wired
           up, and architectures that are entirely missing a cycle counter now
           have a generic fallback path, which uses the highest resolution
           clock available from the timekeeping subsystem.
      
           Some of those clocks can actually be quite good, despite the CPU
           not having a cycle counter of its own, and going off-core for a
           stamp is generally thought to increase jitter, something positive
           from the perspective of entropy gathering. Done very early on in
           the development cycle, this has been sitting in next getting some
           testing for a while now and has relevant acks from the archs, so it
           should be pretty well tested and fine, but is nonetheless the thing
           I'll be keeping my eye on most closely.
      
         - Of particular note with the random_get_entropy() improvements is
           MIPS, which, on CPUs that lack the c0 count register, will now
           combine the high-speed but short-cycle c0 random register with the
           lower-speed but long-cycle generic fallback path.
      
         - With random_get_entropy() now always returning something useful,
           the interrupt handler now collects entropy in a consistent
           construction.
      
         - Rather than comparing two samples of random_get_entropy() for the
           jitter dance, the algorithm now tests many samples, and uses the
           amount of differing ones to determine whether or not jitter entropy
           is usable and how laborious it must be. The problem with comparing
           only two samples was that if the cycle counter was extremely slow,
           but just so happened to be on the cusp of a change, the slowness
           wouldn't be detected. Taking many samples fixes that to some
           degree.
      
           This, combined with the other improvements to random_get_entropy(),
           should make future unification of /dev/random and /dev/urandom
           maybe more possible. At the very least, were we to attempt it again
           today (we're not), it wouldn't break any of Guenter's test rigs
           that broke when we tried it with 5.18. So, not today, but perhaps
           down the road, that's something we can revisit.
      
         - We attempt to reseed the RNG immediately upon waking up from system
           suspend or hibernation, making use of the various timestamps about
           suspend time and such available, as well as the usual inputs such
           as RDRAND when available.
      
         - Batched randomness now falls back to ordinary randomness before the
           RNG is initialized. This provides more consistent guarantees to the
           types of random numbers being returned by the various accessors.
      
         - The "pre-init injection" code is now gone for good. I suspect you
           in particular will be happy to read that, as I recall you
           expressing your distaste for it a few months ago. Instead, to avoid
           a "premature first" issue, while still allowing for maximal amount
           of entropy availability during system boot, the first 128 bits of
           estimated entropy are used immediately as it arrives, with the next
           128 bits being buffered. And, as before, after the RNG has been
           fully initialized, it winds up reseeding anyway a few seconds later
           in most cases. This resulted in a pretty big simplification of the
           initialization code and let us remove various ad-hoc mechanisms
           like the ugly crng_pre_init_inject().
      
         - The RNG no longer pretends to handle the "premature next" security
           model, something that various academics and other RNG designs have
           tried to care about in the past. After an interesting mailing list
           thread, these issues are thought to be a) mainly academic and not
           practical at all, and b) actively harming the real security of the
           RNG by delaying new entropy additions after a potential compromise,
           making a potentially bad situation even worse. As well, in the
           first place, our RNG never even properly handled the premature next
           issue, so removing an incomplete solution to a fake problem was
           particularly nice.
      
           This allowed for numerous other simplifications in the code, which
           is a lot cleaner as a consequence. If you didn't see it before,
           https://lore.kernel.org/lkml/YmlMGx6+uigkGiZ0@zx2c4.com/ may be a
           thread worth skimming through.
      
         - While the interrupt handler received a separate code path years ago
           that avoids locks by using per-cpu data structures and a faster
           mixing algorithm, in order to reduce interrupt latency, input and
           disk events that are triggered in hardirq handlers were still
           hitting locks and more expensive algorithms. Those are now
           redirected to use the faster per-cpu data structures.
      
         - Rather than having the fake-crypto almost-siphash-based random32
           implementation be used right and left, and in many places where
           cryptographically secure randomness is desirable, the batched
           entropy code is now fast enough to replace that.
      
         - As usual, numerous code quality and documentation cleanups. For
           example, the initialization state machine now uses enum symbolic
           constants instead of just hard coding numbers everywhere.
      
         - Since the RNG initializes once, and then is always initialized
           thereafter, a pretty heavy amount of code used during that
           initialization is never used again. It is now completely cordoned
           off using static branches and it winds up in the .text.unlikely
           section so that it doesn't reduce cache compactness after the RNG
           is ready.
      
         - A variety of functions meant for waiting on the RNG to be
           initialized were only used by vsprintf, and in not a particularly
           optimal way. Replacing that usage with a more ordinary setup made
           it possible to remove those functions.
      
         - A cleanup of how we warn userspace about the use of uninitialized
           /dev/urandom and uninitialized get_random_bytes() usage.
           Interestingly, with the change you merged for 5.18 that attempts to
           use jitter (but does not block if it can't), the majority of users
           should never see those warnings for /dev/urandom at all now, and
           the one for in-kernel usage is mainly a debug thing.
      
         - The file_operations struct for /dev/[u]random now implements
           .read_iter and .write_iter instead of .read and .write, allowing it
           to also implement .splice_read and .splice_write, which makes
           splice(2) work again after it was broken here (and in many other
           places in the tree) during the set_fs() removal. This was a bit of
           a last minute arrival from Jens that hasn't had as much time to
           bake, so I'll be keeping my eye on this as well, but it seems
           fairly ordinary. Unfortunately, read_iter() is around 3% slower
           than read() in my tests, which I'm not thrilled about. But Jens and
           Al, spurred by this observation, seem to be making progress in
           removing the bottlenecks on the iter paths in the VFS layer in
           general, which should remove the performance gap for all drivers.
      
         - Assorted other bug fixes, cleanups, and optimizations.
      
         - A small SipHash cleanup"

      lockdown: also lock down previous kgdb use · eadb2f47
      Daniel Thompson authored
      KGDB and KDB allow read and write access to kernel memory, and thus
      should be restricted during lockdown.  An attacker with access to a
      serial port (for example, via a hypervisor console, which some cloud
      vendors provide over the network) could trigger the debugger so it is
      important that the debugger respect the lockdown mode when/if it is
      triggered.
      
      Fix this by integrating lockdown into kdb's existing permissions
      mechanism.  Unfortunately kgdb does not have any permissions mechanism
      (although it certainly could be added later) so, for now, kgdb is simply
      and brutally disabled by immediately exiting the gdb stub without taking
      any action.
      
      For lockdowns established early in the boot (e.g. the normal case) then
      this should be fine but on systems where kgdb has set breakpoints before
      the lockdown is enacted than "bad things" will happen.
