      lan743x: Use correct MAC_CR configuration for 1 GBit speed · 7cdee28c
      Roelof Berg authored
      Corrected the MAC_CR configuration bits for 1 GBit operation. The data
      sheet allows MAC_CR(2:1) to be 10 and also 11 for 1 GBit/s speed, but
      only 10 works correctly.

      r8169: fix failing WoL · 12006848
      Heiner Kallweit authored
      Th referenced change added an extra hw reset to rtl8169_net_suspend()
      what makes WoL fail on few chip versions. Therefore skip the extra
      reset if we're going down and WoL is enabled.
      In rtl_shutdown() rtl8169_hw_reset() is called by rtl8169_net_suspend()
      already if needed, therefore avoid issues issue by removing the extra
      call. The fix was tested on a system with RTL8168g.
      
      Meanwhile rtl8169_hw_reset() does more than a hw reset and should be
      renamed. But that's net-next material.

      net: mdiobus: Disable preemption upon u64_stats update · c7e261d8

      u64_stats: Document writer non-preemptibility requirement · 6501bf87
      Ahmed S. Darwish authored
      The u64_stats mechanism uses sequence counters to protect against 64-bit
      values tearing on 32-bit architectures. Updating such statistics is a
      sequence counter write side critical section.
      
      Preemption must be disabled before entering this seqcount write critical
      section.  Failing to do so, the seqcount read side can preempt the write
      side section and spin for the entire scheduler tick.  If that reader
      belongs to a real-time scheduling class, it can spin forever and the
      kernel will livelock.
      
      Document this statistics update side non-preemptibility requirement.
      
      Reword the introductory paragraph to highlight u64_stats raison d'être:
      64-bit values tearing protection on 32-bit architectures. Divide
      documentation on a basis of internal design vs. usage constraints.
      
      Reword the u64_stats header file top comment to always mention "Reader"
      or "Writer" at the start of each bullet point, making it easier to
      follow which side each point is actually for.
      
      Clarify the statement "whole thing is a NOOP on 64bit arches or UP
      kernels".  For 32-bit UP kernels, preemption is always disabled for the
      statistics read side section.

      net: core: device_rename: Use rwsem instead of a seqcount · 11d6011c
      Ahmed S. Darwish authored
      Sequence counters write paths are critical sections that must never be
      preempted, and blocking, even for CONFIG_PREEMPTION=n, is not allowed.
      
      Commit 5dbe7c17 ("net: fix kernel deadlock with interface rename and
      netdev name retrieval.") handled a deadlock, observed with
      CONFIG_PREEMPTION=n, where the devnet_rename seqcount read side was
      infinitely spinning: it got scheduled after the seqcount write side
      blocked inside its own critical section.
      
      To fix that deadlock, among other issues, the commit added a
      cond_resched() inside the read side section. While this will get the
      non-preemptible kernel eventually unstuck, the seqcount reader is fully
      exhausting its slice just spinning -- until TIF_NEED_RESCHED is set.
      
      The fix is also still broken: if the seqcount reader belongs to a
      real-time scheduling policy, it can spin forever and the kernel will
      livelock.
      
      Disabling preemption over the seqcount write side critical section will
      not work: inside it are a number of GFP_KERNEL allocations and mutex
      locking through the drivers/base/ :: device_rename() call chain.
      
      >From all the above, replace the seqcount with a rwsem.
      
      Fixes: 5dbe7c17 (net: fix kernel deadlock with interface rename and netdev name retrieval.)
      Fixes: 30e6c9fa (net: devnet_rename_seq should be a seqcount)

      geneve: change from tx_error to tx_dropped on missing metadata · 9d149045
      Jiri Benc authored
      If the geneve interface is in collect_md (external) mode, it can't send any
      packets submitted directly to its net interface, as such packets won't have
      metadata attached. This is expected.
      
      However, the kernel itself sends some packets to the interface, most
      notably, IPv6 DAD, IPv6 multicast listener reports, etc. This is not wrong,
      as tunnel metadata can be specified in routing table (although technically,
      that has never worked for IPv6, but hopefully will be fixed eventually) and
      then the interface must correctly participate in IPv6 housekeeping.
      
      The problem is that any such attempt increases the tx_error counter. Just
      bringing up a geneve interface with IPv6 enabled is enough to see a number
      of tx_errors. That causes confusion among users, prompting them to find
      a network error where there is none.
      
      Change the counter used to tx_dropped. That better conveys the meaning
      (there's nothing wrong going on, just some packets are getting dropped) and
      hopefully will make admins panic less.

      net: ena: xdp: update napi budget for DROP and ABORTED · 3921a81c
      Sameeh Jubran authored
      This patch fixes two issues with XDP:
      
      1. If the XDP verdict is XDP_ABORTED we break the loop, which results in
         us handling one buffer per napi cycle instead of the total budget
         (usually 64). To overcome this simply change the xdp_verdict check to
         != XDP_PASS. When the verdict is XDP_PASS, the skb is not expected to
         be NULL.
      
      2. Update the residual budget for XDP_DROP and XDP_ABORTED, since
         packets are handled in these cases.

      seg6: fix seg6_validate_srh() to avoid slab-out-of-bounds · bb986a50
      Ahmed Abdelsalam authored
      The seg6_validate_srh() is used to validate SRH for three cases:
      
      case1: SRH of data-plane SRv6 packets to be processed by the Linux kernel.
      Case2: SRH of the netlink message received  from user-space (iproute2)
      Case3: SRH injected into packets through setsockopt
      
      In case1, the SRH can be encoded in the Reduced way (i.e., first SID is
      carried in DA only and not represented as SID in the SRH) and the
      seg6_validate_srh() now handles this case correctly.
      
      In case2 and case3, the SRH shouldn’t be encoded in the Reduced way
      otherwise we lose the first segment (i.e., the first hop).
      
      The current implementation of the seg6_validate_srh() allow SRH of case2
      and case3 to be encoded in the Reduced way. This leads a slab-out-of-bounds
      problem.
      
      This patch verifies SRH of case1, case2 and case3. Allowing case1 to be
      reduced while preventing SRH of case2 and case3 from being reduced .

      This bug was bisected to commit 0a3e060f ("tipc: add test for Nagle
      algorithm effectiveness"). However, it is not the case, the trouble was
      from the base in the case of zero data length message sending, we would
      unexpectedly make an empty 'txq' queue after the 'tipc_msg_append()' in
      Nagle mode.
      
      A similar crash can be generated even without the bisected patch but at
      the link layer when it accesses the empty queue.
      
      We solve the issues by building at least one buffer to go with socket's
      header and an optional data section that may be empty like what we had
      with the 'tipc_msg_build()'.
      
      Note: the previous commit 4c21daae ("tipc: Fix NULL pointer
      dereference in __tipc_sendstream()") is obsoleted by this one since the
      'txq' will be never empty and the check of 'skb != NULL' is unnecessary
      but it is safe anyway.

      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

        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.
      
        The per-fs changes to make this call this will be in subsequent pull
        requests from Ted and myself.
      
        Summary:
      
         - Introduce DONTCACHE flags for dentries and inodes. This hint will
           cause the VFS to drop the associated objects immediately after the
           last put, so that we can change the file access mode (DAX or page
           cache) on the fly"
