      net: systemport: suppress warnings on failed Rx SKB allocations · 3554e54a
      Doug Berger authored
      The driver is designed to drop Rx packets and reclaim the buffers
      when an allocation fails, and the network interface needs to safely
      handle this packet loss. Therefore, an allocation failure of Rx
      SKBs is relatively benign.
      
      However, the output of the warning message occurs with a high
      scheduling priority that can cause excessive jitter/latency for
      other high priority processing.
      
      This commit suppresses the warning messages to prevent scheduling
      problems while retaining the failure count in the statistics of
      the network interface.

      macsec: avoid to set wrong mtu · 7f327080
      Taehee Yoo authored
      When a macsec interface is created, the mtu is calculated with the lower
      interface's mtu value.
      If the mtu of lower interface is lower than the length, which is needed
      by macsec interface, macsec's mtu value will be overflowed.
      So, if the lower interface's mtu is too low, macsec interface's mtu
      should be set to 0.
      
      Test commands:
          ip link add dummy0 mtu 10 type dummy
          ip link add macsec0 link dummy0 type macsec
          ip link show macsec0
      
      Before:
          11: macsec0@dummy0: <BROADCAST,MULTICAST,M-DOWN> mtu 4294967274
      After:
          11: macsec0@dummy0: <BROADCAST,MULTICAST,M-DOWN> mtu 0

      mm: check that mm is still valid in madvise() · bc0c4d1e
      Linus Torvalds authored
      IORING_OP_MADVISE can end up basically doing mprotect() on the VM of
      another process, which means that it can race with our crazy core dump
      handling which accesses the VM state without holding the mmap_sem
      (because it incorrectly thinks that it is the final user).
      
      This is clearly a core dumping problem, but we've never fixed it the
      right way, and instead have the notion of "check that the mm is still
      ok" using mmget_still_valid() after getting the mmap_sem for writing in
      any situation where we're not the original VM thread.
      
      See commit 04f5866e ("coredump: fix race condition between
      mmget_not_zero()/get_task_mm() and core dumping") for more background on
      this whole mmget_still_valid() thing.  You might want to have a barf bag
      handy when you do.
      
      We're discussing just fixing this properly in the only remaining core
      dumping routines.  But even if we do that, let's make do_madvise() do
      the right thing, and then when we fix core dumping, we can remove all
      these mmget_still_valid() checks.

      afs: Make record checking use TASK_UNINTERRUPTIBLE when appropriate · c4bfda16
      David Howells authored
      When an operation is meant to be done uninterruptibly (such as
      FS.StoreData), we should not be allowing volume and server record checking
      to be interrupted.
      
      Fixes: d2ddc776 ("afs: Overhaul volume and server record caching and fileserver rotation")

      afs: Fix to actually set AFS_SERVER_FL_HAVE_EPOCH · 69cf3978
      David Howells authored
      AFS keeps track of the epoch value from the rxrpc protocol to note (a) when
      a fileserver appears to have restarted and (b) when different endpoints of
      a fileserver do not appear to be associated with the same fileserver
      (ie. all probes back from a fileserver from all of its interfaces should
      carry the same epoch).
      
      However, the AFS_SERVER_FL_HAVE_EPOCH flag that indicates that we've
      received the server's epoch is never set, though it is used.
      
      Fix this to set the flag when we first receive an epoch value from a probe
      sent to the filesystem client from the fileserver.
      
      Fixes: 3bf0fb6f ("afs: Probe multiple fileservers simultaneously")

      afs: Remove some unused bits · be59167c
      David Howells authored
      Remove three bits:
      
       (1) afs_server::no_epoch is neither set nor used.
      
       (2) afs_server::have_result is set and a wakeup is applied to it, but
           nothing looks at it or waits on it.
      
       (3) afs_vl_dump_edestaddrreq() prints afs_addr_list::probed, but nothing
           sets it for VL servers.
