      cifs: remove any preceding delimiter from prefix_path · 11e31647
      Sachin Prabhu authored
      We currently do not check if any delimiter exists before the prefix
      path in cifs_compose_mount_options(). Consequently when building the
      devname using cifs_build_devname() we can end up with multiple
      delimiters separating the UNC and the prefix path.
      
      An issue was reported by the customer mounting a folder within a DFS
      share from a Netapp server which uses McAfee antivirus. We have
      narrowed down the cause to the use of double backslashes in the file
      name used to open the file. This was determined to be caused because of
      additional delimiters as a result of the bug.
      
      In addition to changes in cifs_build_devname(), we also fix
      cifs_parse_devname() to ignore any preceding delimiter for the prefix
      path.
      
      The problem was originally reported on RHEL 6 in RHEL bz 1252721. This
      is the upstream version of the fix. The fix was confirmed by looking at
      the packet capture of a DFS mount.

      cifs: Use file_dentry() · 1f1735cb
      Goldwyn Rodrigues authored
      CIFS may be used as lower layer of overlayfs and accessing f_path.dentry can
      lead to a crash.
      
      Fix by replacing direct access of file->f_path.dentry with the
      file_dentry() accessor, which will always return a native object.

      Pull parallel filesystem directory handling update from Al Viro.
      
      This is the main parallel directory work by Al that makes the vfs layer
      able to do lookup and readdir in parallel within a single directory.
      That's a big change, since this used to be all protected by the
      directory inode mutex.
      
      The inode mutex is replaced by an rwsem, and serialization of lookups of
      a single name is done by a "in-progress" dentry marker.
      
      The series begins with xattr cleanups, and then ends with switching
      filesystems over to actually doing the readdir in parallel (switching to
      the "iterate_shared()" that only takes the read lock).
      
      A more detailed explanation of the process from Al Viro:
       "The xattr work starts with some acl fixes, then switches ->getxattr to
        passing inode and dentry separately.  This is the point where the
        things start to get tricky - that got merged into the very beginning
        of the -rc3-based #work.lookups, to allow untangling the
        security_d_instantiate() mess.  The xattr work itself proceeds to
        switch a lot of filesystems to generic_...xattr(); no complications
        there.
      
        After that initial xattr work, the series then does the following:
      
         - untangle security_d_instantiate()
      
         - convert a bunch of open-coded lookup_one_len_unlocked() to calls of
           that thing; one such place (in overlayfs) actually yields a trivial
           conflict with overlayfs fixes later in the cycle - overlayfs ended
           up switching to a variant of lookup_one_len_unlocked() sans the
           permission checks.  I would've dropped that commit (it gets
           overridden on merge from #ovl-fixes in #for-next; proper resolution
           is to use the variant in mainline fs/overlayfs/super.c), but I
           didn't want to rebase the damn thing - it was fairly late in the
           cycle...
      
         - some filesystems had managed to depend on lookup/lookup exclusion
           for *fs-internal* data structures in a way that would break if we
           relaxed the VFS exclusion.  Fixing hadn't been hard, fortunately.
      
         - core of that series - parallel lookup machinery, replacing
           ->i_mutex with rwsem, making lookup_slow() take it only shared.  At
           that point lookups happen in parallel; lookups on the same name
           wait for the in-progress one to be done with that dentry.
      
           Surprisingly little code, at that - almost all of it is in
           fs/dcache.c, with fs/namei.c changes limited to lookup_slow() -
           making it use the new primitive and actually switching to locking
           shared.
      
         - parallel readdir stuff - first of all, we provide the exclusion on
           per-struct file basis, same as we do for read() vs lseek() for
           regular files.  That takes care of most of the needed exclusion in
           readdir/readdir; however, these guys are trickier than lookups, so
           I went for switching them one-by-one.  To do that, a new method
           '->iterate_shared()' is added and filesystems are switched to it
           as they are either confirmed to be OK with shared lock on directory
           or fixed to be OK with that.  I hope to kill the original method
           come next cycle (almost all in-tree filesystems are switched
           already), but it's still not quite finished.
      
         - several filesystems get switched to parallel readdir.  The
           interesting part here is dealing with dcache preseeding by readdir;
           that needs minor adjustment to be safe with directory locked only
           shared.
      
           Most of the filesystems doing that got switched to in those
           commits.  Important exception: NFS.  Turns out that NFS folks, with
           their, er, insistence on VFS getting the fuck out of the way of the
           Smart Filesystem Code That Knows How And What To Lock(tm) have
           grown the locking of their own.  They had their own homegrown
           rwsem, with lookup/readdir/atomic_open being *writers* (sillyunlink
           is the reader there).  Of course, with VFS getting the fuck out of
           the way, as requested, the actual smarts of the smart filesystem
           code etc. had become exposed...
      
         - do_last/lookup_open/atomic_open cleanups.  As the result, open()
           without O_CREAT locks the directory only shared.  Including the
           ->atomic_open() case.  Backmerge from #for-linus in the middle of
           that - atomic_open() fix got brought in.
      
         - then comes NFS switch to saner (VFS-based ;-) locking, killing the
           homegrown "lookup and readdir are writers" kinda-sorta rwsem.  All
           exclusion for sillyunlink/lookup is done by the parallel lookups
           mechanism.  Exclusion between sillyunlink and rmdir is a real rwsem
           now - rmdir being the writer.
      
           Result: NFS lookups/readdirs/O_CREAT-less opens happen in parallel
           now.
      
         - the rest of the series consists of switching a lot of filesystems
           to parallel readdir; in a lot of cases ->llseek() gets simplified
           as well.  One backmerge in there (again, #for-linus - rockridge
           fix)"

      Pull tracing ring-buffer fixes from Steven Rostedt:
       "Hao Qin reported an integer overflow possibility with signed and
        unsigned numbers in the ring-buffer code.
      
          https://bugzilla.kernel.org/show_bug.cgi?id=118001
      
        At first I did not think this was too much of an issue, because the
        overflow would be caught later when either too much data was allocated
        or it would trigger RB_WARN_ON() which shuts down the ring buffer.
      
        But looking closer into it, I found that the right settings could
        bypass the checks and crash the kernel.  Luckily, this is only
        accessible by root.
      
        The first fix is to convert all the variables into long, such that we
        don't get into issues between 32 bit variables being assigned 64 bit
        ones.  This fixes the RB_WARN_ON() triggering.
      
        The next fix is to get rid of a duplicate DIV_ROUND_UP() that when
        called twice with the right value, can cause a kernel crash.
      
        The first DIV_ROUND_UP() is to normalize the input and it is checked
        against the minimum allowable value.  But then DIV_ROUND_UP() is
        called again, which can overflow due to the (a + b - 1)/b, logic.  The
        first called upped the value, the second can overflow (with the +b
        part).
      
        The second call to DIV_ROUND_UP() came in via a second change a while
        ago and the code is cleaned up to remove it"

      Pull power management updates from Rafael Wysocki:
       "The majority of changes go into the cpufreq subsystem this time.
      
        To me, quite obviously, the biggest ticket item is the new "schedutil"
        governor.  Interestingly enough, it's the first new cpufreq governor
        since the beginning of the git era (except for some out-of-the-tree
        ones).
      
        There are two main differences between it and the existing governors.
        First, it uses the information provided by the scheduler directly for
        making its decisions, so it doesn't have to track anything by itself.
        Second, it can invoke drivers (supporting that feature) to adjust CPU
        performance right away without having to spawn work items to be
        executed in process context or similar.  Currently, the acpi-cpufreq
        driver is the only one supporting that mode of operation, but then it
        is used on a large number of systems.
      
        The "schedutil" governor as included here is very simple and mostly
        regarded as a foundation for future work on the integration of the
        scheduler with CPU power management (in fact, there is work in
        progress on top of it already).  Nevertheless it works and the
        preliminary results obtained with it are encouraging.
      
        There also is some consolidation of CPU frequency management for ARM
        platforms that can add their machine IDs the the new stub dt-platdev
        driver now and that will take care of creating the requisite platform
        device for cpufreq-dt, so it is not necessary to do that in platform
        code any more.  Several ARM platforms are switched over to using this
        generic mechanism.
      
        In addition to that, the intel_pstate driver is now going to respect
        CPU frequency limits set by the platform firmware (or a BMC) and
        provided via the ACPI _PPC object.
      
        The devfreq subsystem is getting a new "passive" governor for SoCs
        subsystems that will depend on somebody else to manage their voltage
        rails and its support for Samsung Exynos SoCs is consolidated.
      
        The rest is support for new hardware (Intel Broxton support in
        intel_idle for one example), bug fixes, optimizations and cleanups in
        a number of places.
      
        Specifics:
      
         - New cpufreq "schedutil" governor (making decisions based on CPU
           utilization information provided by the scheduler and capable of
           switching CPU frequencies right away if the underlying driver
           supports that) and support for fast frequency switching in the
           acpi-cpufreq driver (Rafael Wysocki)
      
         - Consolidation of CPU frequency management on ARM platforms allowing
           them to get rid of some platform-specific boilerplate code if they
           are going to use the cpufreq-dt driver (Viresh Kumar, Finley Xiao,
           Marc Gonzalez)
      
         - Support for ACPI _PPC and CPU frequency limits in the intel_pstate
           driver (Srinivas Pandruvada)
      
         - Fixes and cleanups in the cpufreq core and generic governor code
           (Rafael Wysocki, Sai Gurrappadi)
      
         - intel_pstate driver optimizations and cleanups (Rafael Wysocki,
           Philippe Longepe, Chen Yu, Joe Perches)
      
         - cpufreq powernv driver fixes and cleanups (Akshay Adiga, Shilpasri
           Bhat)
      
         - cpufreq qoriq driver fixes and cleanups (Jia Hongtao)
      
         - ACPI cpufreq driver cleanups (Viresh Kumar)
      
         - Assorted cpufreq driver updates (Ashwin Chaugule, Geliang Tang,
           Javier Martinez Canillas, Paul Gortmaker, Sudeep Holla)
      
         - Assorted cpufreq fixes and cleanups (Joe Perches, Arnd Bergmann)
      
         - Fixes and cleanups in the OPP (Operating Performance Points)
           framework, mostly related to OPP sharing, and reorganization of
           OF-dependent code in it (Viresh Kumar, Arnd Bergmann, Sudeep Holla)
      
         - New "passive" governor for devfreq (for SoC subsystems that will
           rely on someone else for the management of their power resources)
           and consolidation of devfreq support for Exynos platforms, coding
           style and typo fixes for devfreq (Chanwoo Choi, MyungJoo Ham)
      
         - PM core fixes and cleanups, mostly to make it work better with the
           generic power domains (genpd) framework, and updates for that
           framework (Ulf Hansson, Thierry Reding, Colin Ian King)
      
         - Intel Broxton support for the intel_idle driver (Len Brown)
      
         - cpuidle core optimization and fix (Daniel Lezcano, Dave Gerlach)
      
         - ARM cpuidle cleanups (Jisheng Zhang)
      
         - Intel Kabylake support for the RAPL power capping driver (Jacob
           Pan)
      
         - AVS (Adaptive Voltage Switching) rockchip-io driver update (Heiko
           Stuebner)
      
         - Updates for the cpupower tool (Arjun Sreedharan, Colin Ian King,

      ipmi: Fix the I2C address extraction from SPMI tables · 70f95b76
      Corey Minyard authored
      Unlike everywhere else in the IPMI specification, the I2C address
      specified in the SPMI table is not shifted to the left one bit with
      the LSB zero.  Instead it is not shifted with the MSB zero.

      IPMI: reserve memio regions separately · 57a38f13
      Corey Minyard authored
      Commit d61a3ead ("[PATCH] IPMI: reserve I/O ports separately")
      changed the way I/O ports were reserved and includes this comment in
      log:
      
       Some BIOSes reserve disjoint I/O regions in their ACPI tables for the IPMI
       controller.  This causes problems when trying to register the entire I/O
       region.  Therefore we must register each I/O port separately.
      
      There is a similar problem with memio regions on an arm64 platform
      (AMD Seattle). Where I see:
      
       ipmi message handler version 39.2
       ipmi_si AMDI0300:00: probing via device tree
       ipmi_si AMDI0300:00: ipmi_si: probing via ACPI
       ipmi_si AMDI0300:00: [mem 0xe0010000] regsize 1 spacing 4 irq 23
       ipmi_si: Adding ACPI-specified kcs state machine
       IPMI System Interface driver.
       ipmi_si: Trying ACPI-specified kcs state machine at mem \
                address 0xe0010000, slave address 0x0, irq 23
       ipmi_si: Could not set up I/O space
      
      The problem is that the ACPI core registers disjoint regions for the
      platform device:
      
      e0010000-e0010000 : AMDI0300:00
      e0010004-e0010004 : AMDI0300:00
      
      and the ipmi_si driver tries to register one region e0010000-e0010004.
      
      Based on a patch from Mark Salter <msalter@redhat.com>, who also wrote
      all the above text.

      Pull support for killable rwsems from Ingo Molnar:
       "This, by Michal Hocko, implements down_write_killable().
      
        The main usecase will be to update mm_sem usage sites to use this new
        API, to allow the mm-reaper introduced in commit aac45363 ("mm,
        oom: introduce oom reaper") to tear down oom victim address spaces
        asynchronously with minimum latencies and without deadlock worries"
      
      [ The vfs will want it too as the inode lock is changed from a mutex to
        a rwsem due to the parallel lookup and readdir updates ]

      Pull core signal updates from Ingo Molnar:
       "These updates from Stas Sergeev and Andy Lutomirski, improve the
        sigaltstack interface by extending its ABI with the SS_AUTODISARM
        feature, which makes it possible to use swapcontext() in a sighandler
        that works on sigaltstack.  Without this flag, the subsequent signal
        will corrupt the state of the switched-away sighandler.
      
        The inspiration is more robust dosemu signal handling"
