      tipc: fix uninit skb->data in tipc_nl_compat_dumpit() · 47733f9d
      Cong Wang authored
      __tipc_nl_compat_dumpit() has two callers, and it expects them to
      pass a valid nlmsghdr via arg->data. This header is artificial and
      crafted just for __tipc_nl_compat_dumpit().
      
      tipc_nl_compat_publ_dump() does so by putting a genlmsghdr as well
      as some nested attribute, TIPC_NLA_SOCK. But the other caller
      tipc_nl_compat_dumpit() does not, this leaves arg->data uninitialized
      on this call path.
      
      Fix this by just adding a similar nlmsghdr without any payload in
      tipc_nl_compat_dumpit().
      
      This bug exists since day 1, but the recent commit 6ea67769
      ("net: tipc: prepare attrs in __tipc_nl_compat_dumpit()") makes it
      easier to appear.

      net: xdp: pull ethernet header off packet after computing skb->protocol · f8414a8d
      Jason A. Donenfeld authored
      When an XDP program changes the ethernet header protocol field,
      eth_type_trans is used to recalculate skb->protocol. In order for
      eth_type_trans to work correctly, the ethernet header must actually be
      part of the skb data segment, so the code first pushes that onto the
      head of the skb. However, it subsequently forgets to pull it back off,
      making the behavior of the passed-on packet inconsistent between the
      protocol modifying case and the static protocol case. This patch fixes
      the issue by simply pulling the ethernet header back off of the skb
      head.

      bonding: fix a potential double-unregister · 83270702
      Cong Wang authored
      When we tear down a network namespace, we unregister all
      the netdevices within it. So we may queue a slave device
      and a bonding device together in the same unregister queue.
      
      If the only slave device is non-ethernet, it would
      automatically unregister the bonding device as well. Thus,
      we may end up unregistering the bonding device twice.
      
      Workaround this special case by checking reg_state.

      can: j1939: add rxtimer for multipacket broadcast session · 0ae18a82
      Zhang Changzhong authored
      According to SAE J1939/21 (Chapter 5.12.3 and APPENDIX C), for transmit side
      the required time interval between packets of a multipacket broadcast message
      is 50 to 200 ms, the responder shall use a timeout of 250ms (provides margin
      allowing for the maximumm spacing of 200ms). For receive side a timeout will
      occur when a time of greater than 750 ms elapsed between two message packets
      when more packets were expected.
      
      So this patch fix and add rxtimer for multipacket broadcast session.

      can: j1939: abort multipacket broadcast session when timeout occurs · 2b8b2e31
      Zhang Changzhong authored
      If timeout occurs, j1939_tp_rxtimer() first calls hrtimer_start() to restart
      rxtimer, and then calls __j1939_session_cancel() to set session->state =
      J1939_SESSION_WAITING_ABORT. At next timeout expiration, because of the
      J1939_SESSION_WAITING_ABORT session state j1939_tp_rxtimer() will call
      j1939_session_deactivate_activate_next() to deactivate current session, and
      rxtimer won't be set.
      
      But for multipacket broadcast session, __j1939_session_cancel() don't set
      session->state = J1939_SESSION_WAITING_ABORT, thus current session won't be
      deactivate and hrtimer_start() is called to start new rxtimer again and again.
      
      So fix it by moving session->state = J1939_SESSION_WAITING_ABORT out of if
      (!j1939_cb_is_broadcast(&session->skcb)) statement.

      Zhang Changzhong authored
      Currently j1939_tp_im_involved_anydir() in j1939_tp_recv() check the previously
      set flags J1939_ECU_LOCAL_DST and J1939_ECU_LOCAL_SRC of incoming skb, thus
      multipacket broadcast message was aborted by receive side because it may come
      from remote ECUs and have no exact dst address. Similarly, j1939_tp_cmd_recv()
      and j1939_xtp_rx_dat() didn't process broadcast message.
      
      So fix it by checking and process broadcast message in j1939_tp_recv(),
      j1939_tp_cmd_recv() and j1939_xtp_rx_dat().

      drivers/net/wan/hdlc_x25: Added needed_headroom and a skb->len check · 77b981c8
      Xie He authored
      1. Added a skb->len check
      
      This driver expects upper layers to include a pseudo header of 1 byte
      when passing down a skb for transmission. This driver will read this
      1-byte header. This patch added a skb->len check before reading the
      header to make sure the header exists.
      
      2. Added needed_headroom and set hard_header_len to 0
      
      When this driver transmits data,
        first this driver will remove a pseudo header of 1 byte,
        then the lapb module will prepend the LAPB header of 2 or 3 bytes.
      So the value of needed_headroom in this driver should be 3 - 1.
      
      Because this driver has no header_ops, according to the logic of
      af_packet.c, the value of hard_header_len should be 0.
      
      Reason of setting needed_headroom and hard_header_len at this place:
      
      This driver is written using the API of the hdlc module, the hdlc
      module enables this driver (the protocol driver) to run on any hardware
      that has a driver (the hardware driver) written using the API of the
      hdlc module.
      
      Two other hdlc protocol drivers - hdlc_ppp and hdlc_raw_eth, also set
      things like hard_header_len at this place. In hdlc_ppp, it sets
      hard_header_len after attach_hdlc_protocol and before setting dev->type.
      In hdlc_raw_eth, it sets hard_header_len by calling ether_setup after
      attach_hdlc_protocol and after memcpy the settings.
      
      3. Reset needed_headroom when detaching protocols (in hdlc.c)
      
      When detaching a protocol from a hardware device, the hdlc module will
      reset various parameters of the device (including hard_header_len) to
      the default values. We add needed_headroom here so that needed_headroom
      will also be reset.

      bonding: show saner speed for broadcast mode · 4ca0d9ac
      Jarod Wilson authored
      Broadcast mode bonds transmit a copy of all traffic simultaneously out of
      all interfaces, so the "speed" of the bond isn't really the aggregate of
      all interfaces, but rather, the speed of the slowest active interface.
      
      Also, the type of the speed field is u32, not unsigned long, so adjust
      that accordingly, as required to make min() function here without
      complaining about mismatching types.

      i40e: Fix crash during removing i40e driver · 5b6d4a7f
      Grzegorz Szczurek authored
      Fix the reason of crashing system by add waiting time to finish reset
      recovery process before starting remove driver procedure.
      Now VSI is releasing if VSI is not in reset recovery mode.
      Without this fix it was possible to start remove driver if other
      processing command need reset recovery procedure which resulted in
      null pointer dereference. VSI used by the ethtool process has been
      cleared by remove driver process.

      Once we've copied data from the iterator we need to revert in case we
      end up not sending any data.
      
      This bug doesn't trigger with normal 'poll' based tests, because
      we only feed a small chunk of data to kernel after poll indicated
      POLLOUT.  With blocking IO and large writes this triggers. Receiver
      ends up with less data than it should get.
      
      Fixes: 72511aab ("mptcp: avoid blocking in tcp_sendpages")

      sfc: check hash is valid before using it · 06888543
      Edward Cree authored
      On EF100, the RX hash field in the packet prefix may not be valid (e.g.
       if the header parse failed), and this is indicated by a one-bit flag
       elsewhere in the packet prefix.  Only call skb_set_hash() if the
       RSS_HASH_VALID bit is set.

      ====================
      pull-request: can 2020-08-14
      
      this is a pull request of 6 patches for net/master. All patches fix problems in
      the j1939 CAN networking stack.
      
      The first patch is by Eric Dumazet fixes a kernel-infoleak in
      j1939_sk_sock2sockaddr_can().
      
      The remaining 5 patches are by Oleksij Rempel and fix recption of j1939
      messages not orginated by the stack, a use-after-free in j1939_tp_txtimer(),
      ensure that the CAN driver has a ml_priv allocated. These problem were found by
      google's syzbot. Further ETP sessions with block size of less than 255 are
      fixed and a sanity check was added to j1939_xtp_rx_dat_one() to detect packet
      corruption.

         32-bit PV guests are rarely used, are lacking security fixes for
         Meltdown, and can be easily replaced by PVH mode. Another series for
         doing more cleanup will follow soon (removal of 32-bit-only pvops
         functionality).

      This can happen if ptrace() or sigreturn() pokes an LDT selector into FS
      or GS for a task with no LDT and something tries to read the base before
      a return to usermode notices the bad selector and fixes it.
      
      The fix is to make sure ldt pointer is not NULL.

           modules that are used to circumvent _GPL exports. These are modules
           that claim to be GPL licensed while also using symbols from
           proprietary modules. Such modules will be rejected while non-GPL
           modules will inherit the proprietary taint.
