      bpf: fix liveness marking · 8fe2d6cc
      Alexei Starovoitov authored
      while processing Rx = Ry instruction the verifier does
      regs[insn->dst_reg] = regs[insn->src_reg]
      which often clears write mark (when Ry doesn't have it)
      that was just set by check_reg_arg(Rx) prior to the assignment.
      That causes mark_reg_read() to keep marking Rx in this block as
      REG_LIVE_READ (since the logic incorrectly misses that it's
      screened by the write) and in many of its parents (until lucky
      write into the same Rx or beginning of the program).
      That causes is_state_visited() logic to miss many pruning opportunities.
      
      Furthermore mark_reg_read() logic propagates the read mark
      for BPF_REG_FP as well (though it's readonly) which causes
      harmless but unnecssary work during is_state_visited().
      Note that do_propagate_liveness() skips FP correctly,
      so do the same in mark_reg_read() as well.
      It saves 0.2 seconds for the test below

      ipv6: fix net.ipv6.conf.all.accept_dad behaviour for real · a2d3f3e3
      Matteo Croce authored
      Commit 35e015e1 ("ipv6: fix net.ipv6.conf.all interface DAD handlers")
      was intended to affect accept_dad flag handling in such a way that
      DAD operation and mode on a given interface would be selected
      according to the maximum value of conf/{all,interface}/accept_dad.
      
      However, addrconf_dad_begin() checks for particular cases in which we
      need to skip DAD, and this check was modified in the wrong way.
      
      Namely, it was modified so that, if the accept_dad flag is 0 for the
      given interface *or* for all interfaces, DAD would be skipped.
      
      We have instead to skip DAD if accept_dad is 0 for the given interface
      *and* for all interfaces.

      ppp: fix race in ppp device destruction · 6151b8b3
      Guillaume Nault authored
      ppp_release() tries to ensure that netdevices are unregistered before
      decrementing the unit refcount and running ppp_destroy_interface().
      
      This is all fine as long as the the device is unregistered by
      ppp_release(): the unregister_netdevice() call, followed by
      rtnl_unlock(), guarantee that the unregistration process completes
      before rtnl_unlock() returns.
      
      However, the device may be unregistered by other means (like
      ppp_nl_dellink()). If this happens right before ppp_release() calling
      rtnl_lock(), then ppp_release() has to wait for the concurrent
      unregistration code to release the lock.
      But rtnl_unlock() releases the lock before completing the device
      unregistration process. This allows ppp_release() to proceed and
      eventually call ppp_destroy_interface() before the unregistration
      process completes. Calling free_netdev() on this partially unregistered
      device will BUG():

      We could set the ->needs_free_netdev flag on PPP devices and move the
      ppp_destroy_interface() logic in the ->priv_destructor() callback. But
      that'd be quite intrusive as we'd first need to unlink from the other
      channels and units that depend on the device (the ones that used the
      PPPIOCCONNECT and PPPIOCATTACH ioctls).
      
      Instead, we can just let the netdevice hold a reference on its
      ppp_file. This reference is dropped in ->priv_destructor(), at the very
      end of the unregistration process, so that neither ppp_release() nor
      ppp_disconnect_channel() can call ppp_destroy_interface() in the interim.

      dm raid: fix incorrect status output at the end of a "recover" process · 41dcf197
      Jonathan Brassow authored
      There are three important fields that indicate the overall health and
      status of an array: dev_health, sync_ratio, and sync_action.  They tell
      us the condition of the devices in the array, and the degree to which
      the array is synchronized.
      
      This commit fixes a condition that is reported incorrectly.  When a member
      of the array is being rebuilt or a new device is added, the "recover"
      process is used to synchronize it with the rest of the array.  When the
      process is complete, but the sync thread hasn't yet been reaped, it is
      possible for the state of MD to be:
       mddev->recovery = [ MD_RECOVERY_RUNNING MD_RECOVERY_RECOVER MD_RECOVERY_DONE ]
       curr_resync_completed = <max dev size> (but not MaxSector)
       and all rdevs to be In_sync.
      This causes the 'array_in_sync' output parameter that is passed to
      rs_get_progress() to be computed incorrectly and reported as 'false' --
      or not in-sync.  This in turn causes the dev_health status characters to
      be reported as all 'a', rather than the proper 'A'.
      
      This can cause erroneous output for several seconds at a time when tools
      will want to be checking the condition due to events that are raised at
      the end of a sync process.  Fix this by properly calculating the
      'array_in_sync' return parameter in rs_get_progress().
      
      Also, remove an unnecessary intermediate 'recovery_cp' variable in
      rs_get_progress().

      If the vlan is down, free the packet instead of proceeding with other
      processing, or counting it as received.  If vlan interfaces are used
      as slaves for bonding, with arp monitoring for connectivity, if the rx
      counter is seen to be incrementing, then the bond device will not
      observe that the interface is down.

      Pull ARM SoC fixes from Olof Johansson:
       "Our first batch of fixes this release cycle, unfortunately a bit
        noisier than usual. Two major groups stand out:
      
         - Some pinctril dts/dtsi changes for stm32 due to a new driver being
           merged during the merge window, and this aligns the DT contents
           between the old format and the new. This could arguably be moved to
           the next merge window but it also seemed relatively harmless to
           include now.
      
         - Amlogic/meson had driver changes merged that required devicetree
           changes to avoid functional/performance regressions. I've already
           asked them to be more careful about this going forward, and making
           sure drivers are compatible with older DTs when they make these
           kind of changes. The platform is actively being upstreamed so
           there's a few things in flight, we've seen this happen before and
           sometimes it's hard to catch in time.

      Update my imgtec.com and personal email address to my kernel.org one in
      a few places as MIPS will soon no longer be part of Imagination
      Technologies, and add mappings in .mailcap so get_maintainer.pl reports
      the right address.

      dm crypt: reject sector_size feature if device length is not aligned to it · 783874b0

      If a crypt mapping uses optional sector_size feature, additional
      restrictions to mapped device segment size must be applied in
      constructor, otherwise the device activation will fail later.

      ARM: dts: stm32: use right pinctrl compatible for stm32f469 · 2aaae13a
      Alexandre Torgue authored
      Currently, same stm32f429-pinctrl driver is used for stm32f429 and
      stm32f469. As pin map is different between those 2 MCUs,
      a stm32f469-pinctrl driver has been recently added.
      This patch
       -allows to use stm32f469-pinctrl driver for stm32f469 boards
       -reworks stm32 devicetree files to fit with stm32f429 / stm32f469
      
      In the same time it fixes an issue when only MACH_STM32F469 flag is
      selected in menuconfig.

      nl80211: Define policy for packet pattern attributes · ad670233
      Peng Xu authored
      Define a policy for packet pattern attributes in order to fix a
      potential read over the end of the buffer during nla_get_u32()
      of the NL80211_PKTPAT_OFFSET attribute.
      
      Note that the data there can always be read due to SKB allocation
      (with alignment and struct skb_shared_info at the end), but the
      data might be uninitialized. This could be used to leak some data
      from uninitialized vmalloc() memory, but most drivers don't allow
      an offset (so you'd just get -EINVAL if the data is non-zero) or
      just allow it with a fixed value - 100 or 128 bytes, so anything
      above that would get -EINVAL. With brcmfmac the limit is 1500 so
      (at least) one byte could be obtained.

      ARM: dts: stm32: Fix STMPE1600 binding on stm32429i-eval board · 4edd8121
      Alexandre Torgue authored
      To declare gpio interrupt line for STMPE1600, 2 possibilities are offered:
      -use gpio binding (and then the gpiolib interface inside driver)
      -use interrupt binding as each gpio-controller are also interrupt controller
       on stm32f429.
      
      In STMPE 1600 node both (gpio and interrupt) bindings are defined.
      This patch fixes this issue and use only interrupt binding.
