       "I mentioned that while we had fixed the kernel crashes, EEH error

      UBIFS: fix a horrid bug · 605c912b
      Artem Bityutskiy 提交于
      Al Viro pointed me to the fact that '->readdir()' and '->llseek()' have no
      mutual exclusion, which means the 'ubifs_dir_llseek()' can be run while we are
      in the middle of 'ubifs_readdir()'.
      
      This means that 'file->private_data' can be freed while 'ubifs_readdir()' uses
      it, and this is a very bad bug: not only 'ubifs_readdir()' can return garbage,
      but this may corrupt memory and lead to all kinds of problems like crashes an
      security holes.
      
      This patch fixes the problem by using the 'file->f_version' field, which
      '->llseek()' always unconditionally sets to zero. We set it to 1 in
      'ubifs_readdir()' and whenever we detect that it became 0, we know there was a
      seek and it is time to clear the state saved in 'file->private_data'.
      
      I tested this patch by writing a user-space program which runds readdir and
      seek in parallell. I could easily crash the kernel without these patches, but
      could not crash it with these patches.

      UBIFS: prepare to fix a horrid bug · 33f1a63a
      Artem Bityutskiy 提交于
      Al Viro pointed me to the fact that '->readdir()' and '->llseek()' have no
      mutual exclusion, which means the 'ubifs_dir_llseek()' can be run while we are
      in the middle of 'ubifs_readdir()'.
      
      First of all, this means that 'file->private_data' can be freed while
      'ubifs_readdir()' uses it.  But this particular patch does not fix the problem.
      This patch is only a preparation, and the fix will follow next.
      
      In this patch we make 'ubifs_readdir()' stop using 'file->f_pos' directly,
      because 'file->f_pos' can be changed by '->llseek()' at any point. This may
      lead 'ubifs_readdir()' to returning inconsistent data: directory entry names
      may correspond to incorrect file positions.
      
      So here we introduce a local variable 'pos', read 'file->f_pose' once at very
      the beginning, and then stick to 'pos'. The result of this is that when
      'ubifs_dir_llseek()' changes 'file->f_pos' while we are in the middle of
      'ubifs_readdir()', the latter "wins".

      mn10300: Use early_param() to parse "mem=" parameter · e3f12a53
      Akira Takeuchi 提交于
      This fixes the problem that "init=" options may not be passed to kernel
      correctly.
      
      parse_mem_cmdline() of mn10300 arch gets rid of "mem=" string from
      redboot_command_line. Then init_setup() parses the "init=" options from
      static_command_line, which is a copy of redboot_command_line, and keeps
      the pointer to the init options in execute_command variable.
      
      Since the commit 026cee00 upstream (params: <level>_initcall-like kernel
      parameters), static_command_line becomes overwritten by saved_command_line at
      do_initcall_level(). Notice that saved_command_line is a command line
      which includes "mem=" string.
      
      As a result, execute_command may point to weird string by the length of
      "mem=" parameter.
      I noticed this problem when using the command line like this:
      
          mem=128M console=ttyS0,115200 init=/bin/sh
      
      Here is the processing flow of command line parameters.
          start_kernel()
            setup_arch(&command_line)
               parse_mem_cmdline(cmdline_p)
                 * strcpy(boot_command_line, redboot_command_line);
                 * Remove "mem=xxx" from redboot_command_line.
                 * *cmdline_p = redboot_command_line;
            setup_command_line(command_line) <-- command_line is redboot_command_line
              * strcpy(saved_command_line, boot_command_line)
              * strcpy(static_command_line, command_line)
            parse_early_param()
              strlcpy(tmp_cmdline, boot_command_line, COMMAND_LINE_SIZE);
              parse_early_options(tmp_cmdline);
                parse_args("early options", cmdline, NULL, 0, 0, 0, do_early_param);
            parse_args("Booting ..", static_command_line, ...);
              init_setup() <-- save the pointer in execute_command
            rest_init()
              kernel_thread(kernel_init, NULL, CLONE_FS | CLONE_SIGHAND);
      
      At this point, execute_command points to "/bin/sh" string.
      
          kernel_init()
            kernel_init_freeable()
              do_basic_setup()
                do_initcalls()
                  do_initcall_level()
                    (*) strcpy(static_command_line, saved_command_line);
      
      Here, execute_command gets to point to "200" string !!

      powerpc/eeh: Add eeh_dev to the cache during boot · 1abd6018
      Thadeu Lima de Souza Cascardo 提交于
      commit f8f7d63f ("powerpc/eeh: Trace eeh
      device from I/O cache") broke EEH on pseries for devices that were
      present during boot and have not been hotplugged/DLPARed.
      
      eeh_check_failure will get the eeh_dev from the cache, and will get
      NULL. eeh_addr_cache_build adds the addresses to the cache, but eeh_dev
      for the giving pci_device is not set yet. Just reordering the call to
      eeh_addr_cache_insert_dev works fine. The ordering is similar to the one
      in eeh_add_device_late.

      rbd: send snapshot context with writes · d2d1f17a
      Josh Durgin 提交于
      Sending the right snapshot context with each write is required for
      snapshots to work. Due to the ordering of calls, the snapshot context
      is never set for any requests. This causes writes to the current
      version of the image to be reflected in all snapshots, which are
      supposed to be read-only.
      
      This happens because rbd_osd_req_format_write() sets the snapshot
      context based on obj_request->img_request. At this point, however,
      obj_request->img_request has not been set yet, to the snapshot context
      is set to NULL. Fix this by moving rbd_img_obj_request_add(), which
      sets obj_request->img_request, before the osd request formatting
      calls.
      
      This resolves:

      Pull networking fixes from David Miller:
      
       1) Found via trinity:
      
          If you connect up an ipv6 socket to an ipv4 mapped address then an
          ipv6 one, sendmsg() can croak because ip6_sk_dst_check() assumes the
          route cached in the socket is an ipv6 one.  In this case there is an
          ipv4 route attached, so it gets stomped on.
      
          Reported by Dave Jones and Hannes Frederic Sowa, fixed by Eric
          Dumazet.
      
       2) AF_KEY notifications leak some kernel memory to userspace, fix from
          Mathias Krause.
      
       3) DLCI calls __dev_get_by_name() without proper locking, and dlci_del
          doesn't validate that the device being deleted is actually a DLCI
          one.  Fixes from Li Zefan.
      
       4) Length check on bluetooth l2cap information responses is wrong, each
          response type has a different lenth, so we should make sure it's in
          a given range rather than enforce one single valid length.  From
          Jaganath Kanakkassery.
      
       5) Receive FIFO overflow is really easy to trigger in stress scenerios
          in the sh_eth driver, but the event isn't being handled properly at
          all.  Specifically, the mask of error interrupts doesn't include the
          event so we never clear it, resulting in the driver becomming wedged
          processing an interrupt that never gets cleared.
      
          Fix from Sergei Shtylyov.
      
       6) qlcnic sleeps while holding a spinlock, use mdelay() instead of
          msleep().  From Shahed Shaikh.
      
       7) Missing curly braces causes SIP netfilter NAT module to always drop
          packets.  Fix from Balazs Peter Odor.
      
       8) ipt_ULOG in netfilter passes the wrong value to timer setup, causing
          the timer to dereference crap when it fires.  Fix from Gao Feng.
      
       9) Missing RCU protection around txq->axq_acq traversal in
          ath_txq_schedule().  Fix from Felix Fietkau.
      
      10) Idle state transition test in ath9k_htc_config() is reversed, fix
          from Sujith Manoharan.
      
      11) IPV6 forwarding handles unicast Router Alert packets incorrectly.
          It tests the wrong option state.  Previously opt->ra being non-zero
          indicated a router alert marking in the SKB, but now it's indicated
          by a bit in opt->flags.  Fix from YOSHIFUJI Hideaki.
      
      12) SKB leak in GRE tunnel GSO handling, from Eric Dumazet.
      
      13) get_user_pages_fast() error handling in TUN and MACVTAP use the same
          local variable for the base index and the loop iterator for page
          traversal, oops! Fix from Michael S Tsirkin.
      
      14) ipv6_get_lladdr() can fail, and we must therefore check it's return
          value in inet6_set_iftoken().  For from Hannes Frederic Sowa.
      
      15) If you change an interface name and meanwhile can sneak in something
          that looks up the name (like SO_BINDTODEVICE or SIOCGIFNAME) we can
          deadlock with CONFIG_PREEMPT=n.  Fix this by providing a helper
          function that properly uses raw_seqcount_begin().  From Nicolas
          Schichan.
      
      16) Chain noise calibration test is inverted in iwlwifi, fix from
          Nikolay Martynov.
      
      17) Properly set TX iwlwifi descriptor flags for back requests.  Fix
          from Emmanuel Grumbach.
      
      18) We can't assume skb_transport_header() is set in xt_TCPOPTSTRAP
          module, fix from Pablo Neira Ayuso.
      
      19) Some crummy APs don't provide the proper High Throughput info in
          association response frames.  Add a workaround by assume we'll use
          whatever is in the beacon/probe.  Fix from Johannes Berg.
      
      20) mac80211 call to rate_idx_match_mask() swaps two arguments (mask and
          channel width).  Fix from Simon Wunderlich.
      
      21) xt_TCPMSS (like xt_TCPOPTSTRAP) must not try to handle fragmented
          frames.  Fix from Phil Oester.

      39) Fix fragmentation handling SKB leak in netfilter conntrack, we were

      ipv6: ip6_sk_dst_check() must not assume ipv6 dst · a963a37d
      Eric Dumazet 提交于
      It's possible to use AF_INET6 sockets and to connect to an IPv4
      destination. After this, socket dst cache is a pointer to a rtable,
      not rt6_info.
      
      ip6_sk_dst_check() should check the socket dst cache is IPv6, or else
      various corruptions/crashes can happen.

      net: fix kernel deadlock with interface rename and netdev name retrieval. · 5dbe7c17
      Nicolas Schichan 提交于
      When the kernel (compiled with CONFIG_PREEMPT=n) is performing the
      rename of a network interface, it can end up waiting for a workqueue
      to complete. If userland is able to invoke a SIOCGIFNAME ioctl or a
      SO_BINDTODEVICE getsockopt in between, the kernel will deadlock due to
      the fact that read_secklock_begin() will spin forever waiting for the
      writer process (the one doing the interface rename) to update the
      devnet_rename_seq sequence.
      
      This patch fixes the problem by adding a helper (netdev_get_name())
      and using it in the code handling the SIOCGIFNAME ioctl and
      SO_BINDTODEVICE setsockopt.
      
      The netdev_get_name() helper uses raw_seqcount_begin() to avoid
      spinning forever, waiting for devnet_rename_seq->sequence to become
      even. cond_resched() is used in the contended case, before retrying
      the access to give the writer process a chance to finish.
      
      The use of raw_seqcount_begin() will incur some unneeded work in the
      reader process in the contended case, but this is better than
      deadlocking the system.

      Pull late power management and ACPI fixes from Rafael Wysocki:
       "Sorry about the timing of this, but ACPI-based docking stations with
        PCI devices on them and ATA bays would be hardly usable with 3.10
        without it.  We've been working on these fixes for the last couple of
        weeks and everyone involved appears to be reasonably comfortable with
        them now.
      
        The PM part is one fix for a cpufreq regression introduced recently
      
         - Fix for an ACPI dock regression introduced by the recent rework of
           the ACPI-based PCI hotplug code (acpiphp) that caused it to be
           initialized before the ACPI dock driver, which is incorrect (ACPI
           dock has to be initialized before acpiphp so that acpiphp can
           register PCI devices on docking stations with it for PCI hotplug on
           re-dock to work).  From Jiang Liu.
      
         - Fix for PCI resources allocation in the ACPI-based PCI hotplug code
           (acpiphp) that makes it use the same PCI resources assignment rules
           during runtime hotplug that are used during boot (the BIOS' choices
           are now respected in both cases).  This prevents PCI resource
           allocation failures during hotplug from happening in some cases.
           From Jiang Liu.
      
         - Fix for ordering and synchronization issues during hot-removal of
           PCI devices on docking stations.  It makes the ACPI dock code carry
           out the PCI devices removal synchronously during undock instead of
           spawning a separate asynchronous work item to remove each of them
           without even bothering to wait for all those work items to
           complete.  The hot-addition part is changed analogously.
      
         - Fix for a regression (introduced a few releases ago) that removed
           the code to register a hotplug notificaion handler for for ATA
           ports/devices inadvertently which prevented ATA bays hotplug from
           working.  The missing code is added back with some improvements.
           From Aaron Lu.
      
         - Fix for a recent cpufreq regression causing a NULL pointer
           dereference to trigger in od_set_powersave_bias() in some
           situations from Jacob Shin"
