      x86: Fix rebuild with EFI_STUB enabled · 91870824
      Jan Beulich authored
      eboot.o and efi_stub_$(BITS).o didn't get added to "targets", and hence
      their .cmd files don't get included by the build machinery, leading to
      the files always getting rebuilt.
      
      Rather than adding the two files individually, take the opportunity and
      add $(VMLINUX_OBJS) to "targets" instead, thus allowing the assignment
      at the top of the file to be shrunk quite a bit.
      
      At the same time, remove a pointless flags override line - the variable
      assigned to was misspelled anyway, and the options added are
      meaningless for assembly sources.
      
      [ hpa: the patch is not minimal, but I am taking it for -urgent anyway
        since the excess impact of the patch seems to be small enough. ]

      netfilter: don't reset nf_trace in nf_reset() · 124dff01
      Patrick McHardy authored
      Commit 130549fe ("netfilter: reset nf_trace in nf_reset") added code
      to reset nf_trace in nf_reset(). This is wrong and unnecessary.
      
      nf_reset() is used in the following cases:
      
      - when passing packets up the the socket layer, at which point we want to
        release all netfilter references that might keep modules pinned while
        the packet is queued. nf_trace doesn't matter anymore at this point.
      
      - when encapsulating or decapsulating IPsec packets. We want to continue
        tracing these packets after IPsec processing.
      
      - when passing packets through virtual network devices. Only devices on
        that encapsulate in IPv4/v6 matter since otherwise nf_trace is not
        used anymore. Its not entirely clear whether those packets should
        be traced after that, however we've always done that.
      
      - when passing packets through virtual network devices that make the
        packet cross network namespace boundaries. This is the only cases
        where we clearly want to reset nf_trace and is also what the
        original patch intended to fix.
      
      Add a new function nf_reset_trace() and use it in dev_forward_skb() to
      fix this properly.

      GFS2: Issue discards in 512b sectors · b2c87cae
      Bob Peterson authored
      This patch changes GFS2's discard issuing code so that it calls
      function sb_issue_discard rather than blkdev_issue_discard. The
      code was calling blkdev_issue_discard and specifying the correct
      sector offset and sector size, but blkdev_issue_discard expects
      these values to be in terms of 512 byte sectors, even if the native
      sector size for the device is different. Calling sb_issue_discard
      with the BLOCK size instead ensures the correct block-to-512b-sector
      translation. I verified that "minlen" is specified in blocks, so
      comparing it to a number of blocks is correct.

      dm cache: reduce bio front_pad size in writeback mode · 19b0092e
      Mike Snitzer authored
      A recent patch to fix the dm cache target's writethrough mode extended
      the bio's front_pad to include a 1056-byte struct dm_bio_details.
      Writeback mode doesn't need this, so this patch reduces the
      per_bio_data_size to 16 bytes in this case instead of 1096.
      
      The dm_bio_details structure was added in "dm cache: fix writes to
      cache device in writethrough mode" which fixed commit e2e74d61 ("dm
      cache: fix race in writethrough implementation").  In writeback mode
      we avoid allocating the writethrough-specific members of the
      per_bio_data structure (the dm_bio_details structure included).

      dm cache: fix writes to cache device in writethrough mode · b844fe69
      Darrick J. Wong authored
      The dm-cache writethrough strategy introduced by commit e2e74d61
      ("dm cache: fix race in writethrough implementation") issues a bio to
      the origin device, remaps and then issues the bio to the cache device.
      This more conservative in-series approach was selected to favor
      correctness over performance (of the previous parallel writethrough).
      However, this in-series implementation that reuses the same bio to write
      both the origin and cache device didn't take into account that the block
      layer's req_bio_endio() modifies a completing bio's bi_sector and
      bi_size.  So the new writethrough strategy needs to preserve these bio
      fields, and restore them before submission to the cache device,
      otherwise nothing gets written to the cache (because bi_size is 0).
      
      This patch adds a struct dm_bio_details field to struct per_bio_data,
      and uses dm_bio_record() and dm_bio_restore() to ensure the bio is
      restored before reissuing to the cache device.  Adding such a large
      structure to the per_bio_data is not ideal but we can improve this
      later, for now correctness is the important thing.
      
      This problem initially went unnoticed because the dm-cache test-suite
      uses a linear DM device for the dm-cache device's origin device.
      Writethrough worked as expected because DM submits a *clone* of the
      original bio, so the original bio which was reused for the cache was
      never touched.

      MIPS: Delete definition of SA_RESTORER. · 80fa8181
      Ralf Baechle authored
      SA_RESTORER used to be defined as 0x04000000 but only the O32 ABI ever
      supported its use and no libc was using it, so the entire sa-restorer
      functionality was removed with lmo commit 39bffc12c3580ab [Zap sa_restorer.]
      for 2.5.48 retaining only the SA_RESTORER definition as a reminder to avoid
      accidental reuse of the mask bit.
      
      Upstream cdef9602fbf1871a43f0f1b5cea10dd0f275167d [signal: always clear
      sa_restorer on execve] adds code that assumes sa_sigaction has an
      sa_restorer field, if SA_RESTORER is defined which would break MIPS.
      So remove the SA_RESTORER definition before the v3.8.4 merge.

      MIPS: Fix ISA level which causes secondary cache init bypassing and more · adb37892
      Deng-Cheng Zhu authored
      The commit a96102be introduced set_isa() where compatible ISA info is
      also set aside from the one gets passed in. It means, for example, 1004K
      will have MIPS_CPU_ISA_M32R2/M32R1/II/I flags. This leads to things like
      the following inappropriate:
      
      if (c->isa_level == MIPS_CPU_ISA_M32R1 ||
          c->isa_level == MIPS_CPU_ISA_M32R2 ||
          c->isa_level == MIPS_CPU_ISA_M64R1 ||
          c->isa_level == MIPS_CPU_ISA_M64R2)

      MIPS: Alchemy: Fix typo "CONFIG_DEBUG_PCI" · 143f0f65
      Paul Bolle authored
      Commit 7517de34 ("MIPS: Alchemy: Redo
      PCI as platform driver") added a reference to CONFIG_DEBUG_PCI. Change
      it to CONFIG_PCI_DEBUG, as that is a valid Kconfig macro.
      
      Also add a newline to a debugging printk that this fix enables.

      Commit 58b69401 [MIPS: Function tracer: Fix broken function tracing]
      completely broke the function tracer for 64-bit kernels.  The symptom is
      a system hang very early in the boot process.
      
      The fix: Remove/fix $sp adjustments for 64-bit case.

      af_unix: If we don't care about credentials coallesce all messages · 0e82e7f6
      Eric W. Biederman authored
      It was reported that the following LSB test case failed
      https://lsbbugs.linuxfoundation.org/attachment.cgi?id=2144 because we
      were not coallescing unix stream messages when the application was
      expecting us to.
      
      The problem was that the first send was before the socket was accepted
      and thus sock->sk_socket was NULL in maybe_add_creds, and the second
      send after the socket was accepted had a non-NULL value for sk->socket
      and thus we could tell the credentials were not needed so we did not
      bother.
      
      The unnecessary credentials on the first message cause
      unix_stream_recvmsg to start verifying that all messages had the same
      credentials before coallescing and then the coallescing failed because
      the second message had no credentials.
      
      Ignoring credentials when we don't care in unix_stream_recvmsg fixes a
      long standing pessimization which would fail to coallesce messages when
      reading from a unix stream socket if the senders were different even if
      we did not care about their credentials.
      
      I have tested this and verified that the in the LSB test case mentioned
      above that the messages do coallesce now, while the were failing to
      coallesce without this change.

      Revert "af_unix: dont send SCM_CREDENTIAL when dest socket is NULL" · 25da0e3e
      Eric W. Biederman authored
      This reverts commit 14134f65.
      
      The problem that the above patch was meant to address is that af_unix
      messages are not being coallesced because we are sending unnecesarry
      credentials.  Not sending credentials in maybe_add_creds totally
      breaks unconnected unix domain sockets that wish to send credentails
      to other sockets.
      
      In practice this break some versions of udev because they receive a
      message and the sending uid is bogus so they drop the message.

      bonding: remove sysfs before removing devices · 4de79c73
      Veaceslav Falico authored
      We have a race condition if we try to rmmod bonding and simultaneously add
      a bond master through sysfs. In bonding_exit() we first remove the devices
      (through rtnl_link_unregister() ) and only after that we remove the sysfs.
      If we manage to add a device through sysfs after that the devices were
      removed - we'll end up with that device/sysfs structure and with the module
      unloaded.
      
      Fix this by first removing the sysfs and only after that calling
      rtnl_link_unregister().

      net: count hw_addr syncs so that unsync works properly. · 4543fbef
      Vlad Yasevich authored
      A few drivers use dev_uc_sync/unsync to synchronize the
      address lists from master down to slave/lower devices.  In
      some cases (bond/team) a single address list is synched down
      to multiple devices.  At the time of unsync, we have a leak
      in these lower devices, because "synced" is treated as a
      boolean and the address will not be unsynced for anything after
      the first device/call.
      
      Treat "synced" as a count (same as refcount) and allow all
      unsync calls to work.
