      Linus Torvalds authored
      Pull idmapped mounts from Christian Brauner:
       "This introduces idmapped mounts which has been in the making for some
        time. Simply put, different mounts can expose the same file or
        directory with different ownership. This initial implementation comes
        with ports for fat, ext4 and with Christoph's port for xfs with more
        filesystems being actively worked on by independent people and
        maintainers.
      
        Idmapping mounts handle a wide range of long standing use-cases. Here
        are just a few:
      
         - Idmapped mounts make it possible to easily share files between
           multiple users or multiple machines especially in complex
           scenarios. For example, idmapped mounts will be used in the
           implementation of portable home directories in
           systemd-homed.service(8) where they allow users to move their home
           directory to an external storage device and use it on multiple
           computers where they are assigned different uids and gids. This
           effectively makes it possible to assign random uids and gids at
           login time.
      
         - It is possible to share files from the host with unprivileged
           containers without having to change ownership permanently through
           chown(2).
      
         - It is possible to idmap a container's rootfs and without having to
           mangle every file. For example, Chromebooks use it to share the
           user's Download folder with their unprivileged containers in their
           Linux subsystem.
      
         - It is possible to share files between containers with
           non-overlapping idmappings.
      
         - Filesystem that lack a proper concept of ownership such as fat can
           use idmapped mounts to implement discretionary access (DAC)
           permission checking.
      
         - They allow users to efficiently changing ownership on a per-mount
           basis without having to (recursively) chown(2) all files. In
           contrast to chown (2) changing ownership of large sets of files is
           instantenous with idmapped mounts. This is especially useful when
           ownership of a whole root filesystem of a virtual machine or
           container is changed. With idmapped mounts a single syscall
           mount_setattr syscall will be sufficient to change the ownership of
           all files.
      
         - Idmapped mounts always take the current ownership into account as
           idmappings specify what a given uid or gid is supposed to be mapped
           to. This contrasts with the chown(2) syscall which cannot by itself
           take the current ownership of the files it changes into account. It
           simply changes the ownership to the specified uid and gid. This is
           especially problematic when recursively chown(2)ing a large set of
           files which is commong with the aforementioned portable home
           directory and container and vm scenario.
      
         - Idmapped mounts allow to change ownership locally, restricting it
           to specific mounts, and temporarily as the ownership changes only
           apply as long as the mount exists.
      
        Several userspace projects have either already put up patches and
        pull-requests for this feature or will do so should you decide to pull
        this:
      
         - systemd: In a wide variety of scenarios but especially right away
           in their implementation of portable home directories.
      
               https://systemd.io/HOME_DIRECTORY/
      
         - container runtimes: containerd, runC, LXD:To share data between
           host and unprivileged containers, unprivileged and privileged
           containers, etc. The pull request for idmapped mounts support in
           containerd, the default Kubernetes runtime is already up for quite
           a while now: https://github.com/containerd/containerd/pull/4734
      
         - The virtio-fs developers and several users have expressed interest
           in using this feature with virtual machines once virtio-fs is
           ported.
      
         - ChromeOS: Sharing host-directories with unprivileged containers.
      
        I've tightly synced with all those projects and all of those listed
        here have also expressed their need/desire for this feature on the
        mailing list. For more info on how people use this there's a bunch of
        talks about this too. Here's just two recent ones:
      
            https://www.cncf.io/wp-content/uploads/2020/12/Rootless-Containers-in-Gitpod.pdf
            https://fosdem.org/2021/schedule/event/containers_idmap/
      
        This comes with an extensive xfstests suite covering both ext4 and
        xfs:
      
            https://git.kernel.org/brauner/xfstests-dev/h/idmapped_mounts
      
        It covers truncation, creation, opening, xattrs, vfscaps, setid
        execution, setgid inheritance and more both with idmapped and
        non-idmapped mounts. It already helped to discover an unrelated xfs
        setgid inheritance bug which has since been fixed in mainline. It will
        be sent for inclusion with the xfstests project should you decide to
        merge this.
      
        In order to support per-mount idmappings vfsmounts are marked with
        user namespaces. The idmapping of the user namespace will be used to
        map the ids of vfs objects when they are accessed through that mount.
        By default all vfsmounts are marked with the initial user namespace.
        The initial user namespace is used to indicate that a mount is not
        idmapped. All operations behave as before and this is verified in the
        testsuite.
      
        Based on prior discussions we want to attach the whole user namespace
        and not just a dedicated idmapping struct. This allows us to reuse all
        the helpers that already exist for dealing with idmappings instead of
        introducing a whole new range of helpers. In addition, if we decide in
        the future that we are confident enough to enable unprivileged users
        to setup idmapped mounts the permission checking can take into account
        whether the caller is privileged in the user namespace the mount is
        currently marked with.
      
        The user namespace the mount will be marked with can be specified by
        passing a file descriptor refering to the user namespace as an
        argument to the new mount_setattr() syscall together with the new
        MOUNT_ATTR_IDMAP flag. The system call follows the openat2() pattern
        of extensibility.
      
        The following conditions must be met in order to create an idmapped
        mount:
      
         - The caller must currently have the CAP_SYS_ADMIN capability in the
           user namespace the underlying filesystem has been mounted in.
      
         - The underlying filesystem must support idmapped mounts.
      
         - The mount must not already be idmapped. This also implies that the
           idmapping of a mount cannot be altered once it has been idmapped.
      
         - The mount must be a detached/anonymous mount, i.e. it must have
           been created by calling open_tree() with the OPEN_TREE_CLONE flag
           and it must not already have been visible in the filesystem.
      
        The last two points guarantee easier semantics for userspace and the
        kernel and make the implementation significantly simpler.
      
        By default vfsmounts are marked with the initial user namespace and no
        behavioral or performance changes are observed.
      
        The manpage with a detailed description can be found here:
      
            https://git.kernel.org/brauner/man-pages/c/1d7b902e2875a1ff342e036a9f866a995640aea8
      
        In order to support idmapped mounts, filesystems need to be changed
        and mark themselves with the FS_ALLOW_IDMAP flag in fs_flags. The
        patches to convert individual filesystem are not very large or
        complicated overall as can be seen from the included fat, ext4, and
        xfs ports. Patches for other filesystems are actively worked on and
        will be sent out separately. The xfstestsuite can be used to verify
        that port has been done correctly.
      
        The mount_setattr() syscall is motivated independent of the idmapped
        mounts patches and it's been around since July 2019. One of the most
        valuable features of the new mount api is the ability to perform
        mounts based on file descriptors only.
      
        Together with the lookup restrictions available in the openat2()
        RESOLVE_* flag namespace which we added in v5.6 this is the first time
        we are close to hardened and race-free (e.g. symlinks) mounting and
        path resolution.
      
        While userspace has started porting to the new mount api to mount
        proper filesystems and create new bind-mounts it is currently not
        possible to change mount options of an already existing bind mount in
        the new mount api since the mount_setattr() syscall is missing.
      
        With the addition of the mount_setattr() syscall we remove this last
        restriction and userspace can now fully port to the new mount api,
        covering every use-case the old mount api could. We also add the
        crucial ability to recursively change mount options for a whole mount
        tree, both removing and adding mount options at the same time. This
        syscall has been requested multiple times by various people and
        projects.
      
        There is a simple tool available at
      
            https://github.com/brauner/mount-idmapped
      
        that allows to create idmapped mounts so people can play with this
        patch series. I'll add support for the regular mount binary should you
        decide to pull this in the following weeks:

      Kbuild: disable TRIM_UNUSED_KSYMS option · 5cf0fd59
      Linus Torvalds authored
      The removal of EXPORT_UNUSED_SYMBOL() in commit 36794822 looks like
      (and was sold as) a no-op, but it actually had a rather serious and
      subtle side effect: the UNUSED_SYMBOLS option not only enabled the
      removed (unused) functionality, it also _disabled_ the TRIM_UNUSED_KSYMS
      functionality.
      
      And it turns out that TRIM_UNUSED_KSYMS is a huge time waste, and takes
      up a third of the kernel build time for me.  For no actual upside, since
      no distro is likely to ever be able to enable it (because they all
      support external kernel modules).
      
      Rather than re-enable EXPORT_UNUSED_SYMBOL, this just disables the
      TRIM_UNUSED_KSYMS option by marking it broken.  I'm tempted to just
      remove the support entirely, but maybe somebody has a use-case and can
      fix the behavior of it.
      
      I could have just disabled it for COMPILE_TEST, but it really smells
      like the TRIM_UNUSED_KSYMS option is badly done and not really useful,
      so this takes the more direct approach - let's see if anybody ever
      actually notices or complains.

       - Retire EXPORT_UNUSED_SYMBOL() and EXPORT_SYMBOL_GPL_FUTURE(). These
         export types were introduced between 2006 - 2008. All the of the
         unused symbols have been long removed and gpl future symbols were
         converted to gpl quite a long time ago, and I don't believe these
         export types have been used ever since. So, I think it should be safe
         to retire those export types now (Christoph Hellwig)

      gfs2: Don't get stuck with I/O plugged in gfs2_ail1_flush · 17d77684
      Bob Peterson authored
      In gfs2_ail1_flush, we're using I/O plugging to give the block layer a
      better chance of merging I/O requests.  If we're too aggressive here, we
      can end up waiting on I/O to complete while still plugged.  Fix that in
      a way similar to writeback_sb_inodes, except that we can't use
      blk_flush_plug because blk_flush_plug_list is not exported.

      Linus Torvalds authored
      Pull clang LTO updates from Kees Cook:
       "Clang Link Time Optimization.
      
        This is built on the work done preparing for LTO by arm64 folks,
        tracing folks, etc. This includes the core changes as well as the
        remaining pieces for arm64 (LTO has been the default build method on
        Android for about 3 years now, as it is the prerequisite for the
        Control Flow Integrity protections).
      
        While x86 LTO enablement is done, it depends on some pending objtool
        clean-ups. It's possible that I'll send a "part 2" pull request for
        LTO that includes x86 support.
      
        For merge log posterity, and as detailed in commit dc5723b0
        ("kbuild: add support for Clang LTO"), here is the lt;dr to do an LTO
        build:
      
              make LLVM=1 LLVM_IAS=1 defconfig
              scripts/config -e LTO_CLANG_THIN
              make LLVM=1 LLVM_IAS=1
      
        (To do a cross-compile of arm64, add "CROSS_COMPILE=aarch64-linux-gnu-"
        and "ARCH=arm64" to the "make" command lines.)
      
        Summary:
      
         - Clang LTO build infrastructure and arm64-specific enablement (Sami
           Tolvanen)

      Pull powerpc updates from Michael Ellerman:
      
       - A large series adding wrappers for our interrupt handlers, so that
         irq/nmi/user tracking can be isolated in the wrappers rather than
         spread in each handler.
      
       - Conversion of the 32-bit syscall handling into C.
      
       - A series from Nick to streamline our TLB flushing when using the
         Radix MMU.
      
       - Switch to using queued spinlocks by default for 64-bit server CPUs.
      
       - A rework of our PCI probing so that it happens later in boot, when
         more generic infrastructure is available.
      
       - Two small fixes to allow 32-bit little-endian processes to run on
         64-bit kernels.
      
       - Other smaller features, fixes & cleanups.

       - Update to the way irqs and preemption is tracked via the trace event
         PC field
      
       - Fix handling of unregistering event failing due to allocate memory.
         This is only triggered by failure injection, as it is pretty much
         guaranteed to have less than a page allocation succeed.
      
       - Do not show the useless "filter" or "enable" files for the "ftrace"
         trace system, as they have no effect on doing anything.
      
       - Add a warning if kprobes are registered more than once.
      
       - Synthetic events now have their fields parsed by semicolons. Old
         formats without semicolons will still work, but new features will
         require them.
      
       - New option to allow trace events to show %p without hashing in trace
         file. The trace file can only be read by root, and reading the raw
         event buffer did not have any pointers hashed, so this does not
         expose anything new.
      
       - New directory in tools called tools/tracing, where a new tool that
         reads sequential latency reports from the ftrace latency tracers.
      
       - Other minor fixes and cleanups.

      Merge tag 'perf-tools-for-v5.12-2020-02-19' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux
      
      Pull perf tool updates from Arnaldo Carvalho de Melo:
       "New features:
      
         - Support instruction latency in 'perf report', with both memory
           latency (weight) and instruction latency information, users can
           locate expensive load instructions and understand time spent in
           different stages.
      
         - Extend 'perf c2c' to display the number of loads which were blocked
           by data or address conflict.
      
         - Add 'perf stat' support for L2 topdown events in systems such as
           Intel's Sapphire rapids server.
      
         - Add support for PERF_SAMPLE_CODE_PAGE_SIZE in various tools, as a
           sort key, for instance:
      
              perf report --stdio --sort=comm,symbol,code_page_size
      
         - New 'perf daemon' command to run long running sessions while
           providing a way to control the enablement of events without
           restarting a traditional 'perf record' session.
      
         - Enable counting events for BPF programs in 'perf stat' just like
           for other targets (tid, cgroup, cpu, etc), e.g.:
      
              # perf stat -e ref-cycles,cycles -b 254 -I 1000
                 1.487903822            115,200      ref-cycles
                 1.487903822             86,012      cycles
                 2.489147029             80,560      ref-cycles
                 2.489147029             73,784      cycles
              ^C
      
           The example above counts 'cycles' and 'ref-cycles' of BPF program
           of id 254. It is similar to bpftool-prog-profile command, but more
           flexible.
      
         - Support the new layout for PERF_RECORD_MMAP2 to carry the DSO
           build-id using infrastructure generalised from the eBPF subsystem,
           removing the need for traversing the perf.data file to collect
           build-ids at the end of 'perf record' sessions and helping with
           long running sessions where binaries can get replaced in updates,
           leading to possible mis-resolution of symbols.
      
         - Support filtering by hex address in 'perf script'.
      
         - Support DSO filter in 'perf script', like in other perf tools.
      
         - Add namespaces support to 'perf inject'
      
         - Add support for SDT (Dtrace Style Markers) events on ARM64.
      
        perf record:
      
         - Fix handling of eventfd() when draining a buffer in 'perf record'.
      
         - Improvements to the generation of metadata events for pre-existing
           threads (mmaps, comm, etc), speeding up the work done at the start
           of system wide or per CPU 'perf record' sessions.
      
        Hardware tracing:
      
         - Initial support for tracing KVM with Intel PT.
      
         - Intel PT fixes for IPC
      
         - Support Intel PT PSB (synchronization packets) events.
      
         - Automatically group aux-output events to overcome --filter syntax.
      
         - Enable PERF_SAMPLE_DATA_SRC on ARMs SPE.
      
         - Update ARM's CoreSight hardware tracing OpenCSD library to v1.0.0.
      
        perf annotate TUI:
      
         - Fix handling of 'k' ("show line number") hotkey
      
         - Fix jump parsing for C++ code.
      
        perf probe:
      
         - Add protection to avoid endless loop.
      
        cgroups:
      
         - Avoid reading cgroup mountpoint multiple times, caching it.
      
         - Fix handling of cgroup v1/v2 in mixed hierarchy.
      
        Symbol resolving:
      
         - Add OCaml symbol demangling.
      
         - Further fixes for handling PE executables when using perf with Wine
           and .exe/.dll files.
      
         - Fix 'perf unwind' DSO handling.
      
         - Resolve symbols against debug file first, to deal with artifacts
           related to LTO.
      
         - Fix gap between kernel end and module start on powerpc.
      
        Reporting tools:
      
         - The DSO filter shouldn't show samples in unresolved maps.
      
         - Improve debuginfod support in various tools.
      
        build ids:
      
         - Fix 16-byte build ids in 'perf buildid-cache', add a 'perf test'
           entry for that case.
      
        perf test:
      
         - Support for PERF_SAMPLE_WEIGHT_STRUCT.
      
         - Add test case for PERF_SAMPLE_CODE_PAGE_SIZE.
      
         - Shell based tests for 'perf daemon's commands ('start', 'stop,
           'reconfig', 'list', etc).
      
         - ARM cs-etm 'perf test' fixes.
      
         - Add parse-metric memory bandwidth testcase.
      
        Compiler related:
      
         - Fix 'perf probe' kretprobe issue caused by gcc 11 bug when used
           with -fpatchable-function-entry.
      
         - Fix ARM64 build with gcc 11's -Wformat-overflow.
      
         - Fix unaligned access in sample parsing test.
      
         - Fix printf conversion specifier for IP addresses on arm64, s390 and
           powerpc.
      
        Arch specific:
      
         - Support exposing Performance Monitor Counter SPRs as part of
           extended regs on powerpc.
      
         - Add JSON 'perf stat' metrics for ARM64's imx8mp, imx8mq and imx8mn
           DDR, fix imx8mm ones.
      
         - Fix common and uarch events for ARM64's A76 and Ampere eMag"
