      UBI: init even if MTD device cannot be attached, if built into kernel · af7ad7a0
      Marc Kleine-Budde authored
      UBI can be built into the kernel or be compiled as a kernel module.
      Further on the command line one can specify MTD devices to be attach to
      UBI while loading. In the current implementation the UBI driver refuses
      to load if one of the MTD devices cannot be attached.
      
      Consider:
      1) UBI compiled into the kernel and
      2) a MTD device specified on the command line and
      3) this MTD device contains bogus data (for whatever reason).
      
      During init UBI tries to attach the MTD device is this fails the whole
      UBI subsystem isn't initialized. Later the userspace cannot attach any
      MTD to UBI because UBI isn't loaded.
      
      This patch keeps the current behaviour: if UBI is compiled as a module
      and a MTD device cannot be attached the UBI module cannot be loaded,
      but changes it for the UBI-is-built-into-the-kernel usecase.
      
      If UBI is builtin, a not attachable MTD device doen't stop UBI from
      initializing. This slightly modifies the behaviour if multiple MTD
      devices are specified on the command line. Now every MTD device is
      probed and, if possible, attached, i.e. a faulty MTD device doesn't
      stop the others from being attached.

      packet : remove init_net restriction · 1c4f0197
      Daniel Lezcano authored
      The af_packet protocol is used by Perl to do ioctls as reported by
      Stephane Riviere:
      
      "Net::RawIP relies on SIOCGIFADDR et SIOCGIFHWADDR to get the IP and MAC
      addresses of the network interface."
      
      But in a new network namespace these ioctl fail because it is disabled for
      a namespace different from the init_net_ns.
      
      These two lines should not be there as af_inet and af_packet are
      namespace aware since a long time now. I suppose we forget to remove these
      lines because we sent the af_packet first, before af_inet was supported.

      WAN: flush tx_queue in hdlc_ppp to prevent panic on rmmod hw_driver. · 31f634a6
      Krzysztof Halasa authored
      tx_queue is used as a temporary queue when not allowed to queue skb
      directly to the hw device driver (which may sleep). Most paths flush
      it before returning, but ppp_start() currently cannot. Make sure we
      don't leave skbs pointing to a non-existent device.
      
      Thanks to Michael Barkowski for reporting this problem.

      ACPI: EC: Limit burst to 64 bits · 2060c445
      Alexey Starikovskiy authored
      access_bit_width field is u8 in ACPICA, thus 256 value written to it
      becomes 0, causing divide by zero later.
      
      Proper fix would be to remove access_bit_width at all, just because
      we already have access_byte_width, which is access_bit_width / 8.
      Limit access width to 64 bit for now.

      xfs: don't warn on EAGAIN in inode reclaim · f1d486a3
      Dave Chinner authored
      Any inode reclaim flush that returns EAGAIN will result in the inode
      reclaim being attempted again later. There is no need to issue a
      warning into the logs about this situation.

      xfs: ensure that sync updates the log tail correctly · b6f8dd49
      Dave Chinner authored
      Updates to the VFS layer removed an extra ->sync_fs call into the
      filesystem during the sync process (from the quota code).
      Unfortunately the sync code was unknowingly relying on this call to
      make sure metadata buffers were flushed via a xfs_buftarg_flush()
      call to move the tail of the log forward in memory before the final
      transactions of the sync process were issued.
      
      As a result, the old code would write a very recent log tail value
      to the log by the end of the sync process, and so a subsequent crash
      would leave nothing for log recovery to do. Hence in qa test 182,
      log recovery only replayed a small handle for inode fsync
      transactions in this case.
      
      However, with the removal of the extra ->sync_fs call, the log tail
      was now not moved forward with the inode fsync transactions near the
      end of the sync procese the first (and only) buftarg flush occurred
      after these transactions went to disk. The result is that log
      recovery now sees a large number of transactions for metadata that
      is already on disk.
      
      This usually isn't a problem, but when the transactions include
      inode chunk allocation, the inode create transactions and all
      subsequent changes are replayed as we cannt rely on what is on disk
      is valid. As a result, if the inode was written and contains
      unlogged changes, the unlogged changes are lost, thereby violating
      sync semantics.
      
      The fix is to always issue a transaction after the buftarg flush
      occurs is the log iѕ not idle or covered. This results in a dummy
      transaction being written that contains the up-to-date log tail
      value, which will be very recent. Indeed, it will be at least as
      recent as the old code would have left on disk, so log recovery
      will behave exactly as it used to in this situation.
