      genetlink: fix memory leaks in genl_family_rcv_msg_dumpit() · c36f0555
      Cong Wang authored
      There are two kinds of memory leaks in genl_family_rcv_msg_dumpit():
      
      1. Before we call ops->start(), whenever an error happens, we forget
         to free the memory allocated in genl_family_rcv_msg_dumpit().
      
      2. When ops->start() fails, the 'info' has been already installed on
         the per socket control block, so we should not free it here. More
         importantly, nlk->cb_running is still false at this point, so
         netlink_sock_destruct() cannot free it either.
      
      The first kind of memory leaks is easier to resolve, but the second
      one requires some deeper thoughts.
      
      After reviewing how netfilter handles this, the most elegant solution
      I find is just to use a similar way to allocate the memory, that is,
      moving memory allocations from caller into ops->start(). With this,
      we can solve both kinds of memory leaks: for 1), no memory allocation
      happens before ops->start(); for 2), ops->start() handles its own
      failures and 'info' is installed to the socket control block only
      when success. The only ugliness here is we have to pass all local
      variables on stack via a struct, but this is not hard to understand.
      
      Alternatively, we can introduce a ops->free() to solve this too,
      but it is overkill as only genetlink has this problem so far.
      
      Fixes: 1927f41a ("net: genetlink: introduce dump info struct to be available during dumpit op")

      Pull thread updates from Christian Brauner:
       "We have been discussing using pidfds to attach to namespaces for quite
        a while and the patches have in one form or another already existed
        for about a year. But I wanted to wait to see how the general api
        would be received and adopted.
      
        This contains the changes to make it possible to use pidfds to attach
        to the namespaces of a process, i.e. they can be passed as the first
        argument to the setns() syscall.
      
        When only a single namespace type is specified the semantics are
        equivalent to passing an nsfd. That means setns(nsfd, CLONE_NEWNET)
        equals setns(pidfd, CLONE_NEWNET).
      
        However, when a pidfd is passed, multiple namespace flags can be
        specified in the second setns() argument and setns() will attach the
        caller to all the specified namespaces all at once or to none of them.
      
        Specifying 0 is not valid together with a pidfd. Here are just two
        obvious examples:
      
          setns(pidfd, CLONE_NEWPID | CLONE_NEWNS | CLONE_NEWNET);
          setns(pidfd, CLONE_NEWUSER);
      
        Allowing to also attach subsets of namespaces supports various
        use-cases where callers setns to a subset of namespaces to retain
        privilege, perform an action and then re-attach another subset of
        namespaces.
      
        Apart from significantly reducing the number of syscalls needed to
        attach to all currently supported namespaces (eight "open+setns"
        sequences vs just a single "setns()"), this also allows atomic setns
        to a set of namespaces, i.e. either attaching to all namespaces
        succeeds or we fail without having changed anything.
      
        This is centered around a new internal struct nsset which holds all
        information necessary for a task to switch to a new set of namespaces
        atomically. Fwiw, with this change a pidfd becomes the only token
        needed to interact with a container. I'm expecting this to be
        picked-up by util-linux for nsenter rather soon.
      
        Associated with this change is a shiny new test-suite dedicated to
        setns() (for pidfds and nsfds alike)"

       "Highlights:
      
         - speedup dead root detection during orphan cleanup, eg. when there
           are many deleted subvolumes waiting to be cleaned, the trees are
           now looked up in radix tree instead of a O(N^2) search
      
         - snapshot creation with inherited qgroup will mark the qgroup
           inconsistent, requires a rescan
      
         - send will emit file capabilities after chown, this produces a
           stream that does not need postprocessing to set the capabilities
           again
      
         - direct io ported to iomap infrastructure, cleaned up and simplified
           code, notably removing last use of struct buffer_head in btrfs code
      
        Core changes:
      
         - factor out backreference iteration, to be used by ordinary
           backreferences and relocation code
      
         - improved global block reserve utilization
            * better logic to serialize requests
            * increased maximum available for unlink
            * improved handling on large pages (64K)
      
         - direct io cleanups and fixes
            * simplify layering, where cloned bios were unnecessarily created
              for some cases
            * error handling fixes (submit, endio)
            * remove repair worker thread, used to avoid deadlocks during
              repair
      
         - refactored block group reading code, preparatory work for new type
           of block group storage that should improve mount time on large
           filesystems
      
        Cleanups:
      
         - cleaned up (and slightly sped up) set/get helpers for metadata data
           structure members
      
         - root bit REF_COWS got renamed to SHAREABLE to reflect the that the
           blocks of the tree get shared either among subvolumes or with the
           relocation trees
      
        Fixes:
      
         - when subvolume deletion fails due to ENOSPC, the filesystem is not
           turned read-only
      
         - device scan deals with devices from other filesystems that changed
           ownership due to overwrite (mkfs)
      
         - fix a race between scrub and block group removal/allocation
      
         - fix long standing bug of a runaway balance operation, printing the
           same line to the syslog, caused by a stale status bit on a reloc
           tree that prevented progress
      
         - fix corrupt log due to concurrent fsync of inodes with shared
           extents

       "This time around, we're hoisting the DONTCACHE flag from XFS into the
        VFS so that we can make the incore DAX mode changes become effective
        sooner.
      
        We can't change the file data access mode on a live inode because we
        don't have a safe way to change the file ops pointers. The incore
        state change becomes effective at inode loading time, which can happen
        if the inode is evicted. Therefore, we're making it so that
        filesystems can ask the VFS to evict the inode as soon as the last
        holder drops.

      Pull DAX updates part one from Darrick Wong:
       "After many years of LKML-wrangling about how to enable programs to
        query and influence the file data access mode (DAX) when a filesystem
        resides on storage devices such as persistent memory, Ira Weiny has
        emerged with a proposed set of standard behaviors that has not been
        shot down by anyone! We're more or less standardizing on the current
        XFS behavior and adapting ext4 to do the same.
      
        This is the first of a handful pull requests that will make ext4 and
        XFS present a consistent interface for user programs that care about
        DAX. We add a statx attribute that programs can check to see if DAX is
        enabled on a particular file. Then, we update the DAX documentation to
        spell out the user-visible behaviors that filesystems will guarantee
        (until the next storage industry shakeup). The on-disk inode flag has
        been in XFS for a few years now.
      
        Summary:
      
         - Clean up io_is_direct.
      
         - Add a new statx flag to indicate when file data access is being
           done via DAX (as opposed to the page cache).
      
         - Update the documentation for how system administrators and
           application programmers can take advantage of the (still
           experimental DAX) feature"

      Pull xfs updates from Darrick Wong:
       "Most of the changes this cycle are refactoring of existing code in
        preparation for things landing in the future.
      
        We also fixed various problems and deficiencies in the quota
        implementation, and (I hope) the last of the stale read vectors by
        forcing write allocations to go through the unwritten state until the
        write completes.
      
        Summary:
      
         - Various cleanups to remove dead code, unnecessary conditionals,
           asserts, etc.
      
         - Fix a linker warning caused by xfs stuffing '-g' into CFLAGS
           redundantly.
      
         - Tighten up our dmesg logging to ensure that everything is prefixed
           with 'XFS' for easier grepping.
      
         - Kill a bunch of typedefs.
      
         - Refactor the deferred ops code to reduce indirect function calls.
      
         - Increase type-safety with the deferred ops code.
      
         - Make the DAX mount options a tri-state.
      
         - Fix some error handling problems in the inode flush code and clean
           up other inode flush warts.
      
         - Refactor log recovery so that each log item recovery functions now
           live with the other log item processing code.
      
         - Fix some SPDX forms.
      
         - Fix quota counter corruption if the fs crashes after running
           quotacheck but before any dquots get logged.
      
         - Don't fail metadata verification on zero-entry attr leaf blocks,
           since they're just part of the disk format now due to a historic
           lack of log atomicity.
      
         - Don't allow SWAPEXT between files with different [ugp]id when
           quotas are enabled.
      
         - Refactor inode fork reading and verification to run directly from
           the inode-from-disk function. This means that we now actually
           guarantee that _iget'ted inodes are totally verified and ready to
           go.
      
         - Move the incore inode fork format and extent counts to the ifork
           structure.
      
         - Scalability improvements by reducing cacheline pingponging in
           struct xfs_mount.
      
         - More scalability improvements by removing m_active_trans from the
           hot path.
      
         - Fix inode counter update sanity checking to run /only/ on debug
           kernels.
      
         - Fix longstanding inconsistency in what error code we return when a
           program hits project quota limits (ENOSPC).
      
         - Fix group quota returning the wrong error code when a program hits
           group quota limits.
      
         - Fix per-type quota limits and grace periods for group and project
           quotas so that they actually work.
      
         - Allow extension of individual grace periods.
      
         - Refactor the non-reclaim inode radix tree walking code to remove a
           bunch of stupid little functions and straighten out the
           inconsistent naming schemes.
      
         - Fix a bug in speculative preallocation where we measured a new
           allocation based on the last extent mapping in the file instead of
           looking farther for the last contiguous space allocation.
      
         - Force delalloc writes to unwritten extents. This closes a stale
           disk contents exposure vector if the system goes down before the
           write completes.
      
         - More lockdep whackamole"

      Pull SELinux updates from Paul Moore:
       "The highlights:
      
         - A number of improvements to various SELinux internal data
           structures to help improve performance. We move the role
           transitions into a hash table. In the content structure we shift
           from hashing the content string (aka SELinux label) to the
           structure itself, when it is valid. This last change not only
           offers a speedup, but it helps us simplify the code some as well.
      
         - Add a new SELinux policy version which allows for a more space
           efficient way of storing the filename transitions in the binary
           policy. Given the default Fedora SELinux policy with the unconfined
           module enabled, this change drops the policy size from ~7.6MB to
           ~3.3MB. The kernel policy load time dropped as well.
      
         - Some fixes to the error handling code in the policy parser to
           properly return error codes when things go wrong"

      Thadeu Lima de Souza Cascardo authored
      When running with conntrack rules, the dropped overlap fragments may cause
      EPERM to be returned to sendto. Instead of completely failing, just ignore
      those errors and continue. If this causes packets with overlap fragments to
      be dropped as expected, that is okay. And if it causes packets that are
      expected to be received to be dropped, which should not happen, it will be
      detected as failure.

      ====================
      tipc: revert two patches
      
      We revert two patches:
      
      tipc: Fix potential tipc_node refcnt leak in tipc_rcv
      tipc: Fix potential tipc_aead refcnt leak in tipc_crypto_rcv
      
      which prevented TIPC encryption from working properly and caused kernel
      panic.

      Tuong Lien authored
      This reverts commit 441870ee.
      
      Like the previous patch in this series, we revert the above commit that
      causes similar issues with the 'aead' object.

      This reverts commit de058420.
      
      There is no actual tipc_node refcnt leak as stated in the above commit.
      The refcnt is hold carefully for the case of an asynchronous decryption
      (i.e. -EINPROGRESS/-EBUSY and skb = NULL is returned), so that the node
      object cannot be freed in the meantime. The counter will be re-balanced
      when the operation's callback arrives with the decrypted buffer if any.
      In other cases, e.g. a synchronous crypto the counter will be decreased
      immediately when it is done.
      
      Now with that commit, a kernel panic will occur when there is no node
      found (i.e. n = NULL) in the 'tipc_rcv()' or a premature release of the
      node object.
      
      This commit solves the issues by reverting the said commit, but keeping
      one valid case that the 'skb_linearize()' is failed.

      vmxnet3: allow rx flow hash ops only when rss is enabled · 11e877b2
      Ronak Doshi authored
      It makes sense to allow changes to get/set rx flow hash callback only
      when rss is enabled. This patch restricts get_rss_hash_opts and
      set_rss_hash_opts methods to allow querying and configuring different
      Rx flow hash configurations only when rss is enabled
