      nfc: pn533: Add poll mod list filling check · febccb39
      Aleksandr Mishin authored
      In case of im_protocols value is 1 and tm_protocols value is 0 this
      combination successfully passes the check
      'if (!im_protocols && !tm_protocols)' in the nfc_start_poll().
      But then after pn533_poll_create_mod_list() call in pn533_start_poll()
      poll mod list will remain empty and dev->poll_mod_count will remain 0
      which lead to division by zero.
      
      Normally no im protocol has value 1 in the mask, so this combination is
      not expected by driver. But these protocol values actually come from
      userspace via Netlink interface (NFC_CMD_START_POLL operation). So a
      broken or malicious program may pass a message containing a "bad"
      combination of protocol parameter values so that dev->poll_mod_count
      is not incremented inside pn533_poll_create_mod_list(), thus leading
      to division by zero.
      Call trace looks like:
      nfc_genl_start_poll()
        nfc_start_poll()
          ->start_poll()
          pn533_start_poll()
      
      Add poll mod list filling check.

      Matthieu Baerts says:
      
      ====================
      mptcp: more fixes for the in-kernel PM
      
      Here is a new batch of fixes for the MPTCP in-kernel path-manager:
      
      Patch 1 ensures the address ID is set to 0 when the path-manager sends
      an ADD_ADDR for the address of the initial subflow. The same fix is
      applied when a new subflow is created re-using this special address. A
      fix for v6.0.
      
      Patch 2 is similar, but for the case where an endpoint is removed: if
      this endpoint was used for the initial address, it is important to send
      a RM_ADDR with this ID set to 0, and look for existing subflows with the
      ID set to 0. A fix for v6.0 as well.
      
      Patch 3 validates the two previous patches.
      
      Patch 4 makes the PM selecting an "active" path to send an address
      notification in an ACK, instead of taking the first path in the list. A
      fix for v5.11.
      
      Patch 5 fixes skipping the establishment of a new subflow if a previous
      subflow using the same pair of addresses is being closed. A fix for
      v5.13.
      
      Patch 6 resets the ID linked to the initial subflow when the linked
      endpoint is re-added, possibly with a different ID. A fix for v6.0.
      
      Patch 7 validates the three previous patches.
      
      Patch 8 is a small fix for the MPTCP Join selftest, when being used with
      older subflows not supporting all MIB counters. A fix for a commit
      introduced in v6.4, but backported up to v5.10.
      
      Patch 9 avoids the PM to try to close the initial subflow multiple
      times, and increment counters while nothing happened. A fix for v5.10.
      
      Patch 10 stops incrementing local_addr_used and add_addr_accepted
      counters when dealing with the address ID 0, because these counters are
      not taking into account the initial subflow, and are then not
      decremented when the linked addresses are removed. A fix for v6.0.
      
      Patch 11 validates the previous patch.
      
      Patch 12 avoids the PM to send multiple SUB_CLOSED events for the
      initial subflow. A fix for v5.12.
      
      Patch 13 validates the previous patch.
      
      Patch 14 stops treating the ADD_ADDR 0 as a new address, and accepts it
      in order to re-create the initial subflow if it has been closed, even if
      the limit for *new* addresses -- not taking into account the address of
      the initial subflow -- has been reached. A fix for v5.10.
      
      Patch 15 validates the previous patch.

      This test extends "delete re-add signal" to validate the previous
      commit: when the 'signal' endpoint linked to the initial subflow (ID 0)
      is re-added multiple times, it will re-send the ADD_ADDR with id 0. The
      client should still be able to re-create this subflow, even if the
      add_addr_accepted limit has been reached as this special address is not
      considered as a new address.

      mptcp: pm: ADD_ADDR 0 is not a new address · 57f86203
      Matthieu Baerts (NGI0) authored
      The ADD_ADDR 0 with the address from the initial subflow should not be
      considered as a new address: this is not something new. If the host
      receives it, it simply means that the address is available again.
      
      When receiving an ADD_ADDR for the ID 0, the PM already doesn't consider
      it as new by not incrementing the 'add_addr_accepted' counter. But the
      'accept_addr' might not be set if the limit has already been reached:
      this can be bypassed in this case. But before, it is important to check
      that this ADD_ADDR for the ID 0 is for the same address as the initial
      subflow. If not, it is not something that should happen, and the
      ADD_ADDR can be ignored.
      
      Note that if an ADD_ADDR is received while there is already a subflow
      opened using the same address, this ADD_ADDR is ignored as well. It
      means that if multiple ADD_ADDR for ID 0 are received, there will not be
      any duplicated subflows created by the client.

      mptcp: avoid duplicated SUB_CLOSED events · d82809b6
      Matthieu Baerts (NGI0) authored
      The initial subflow might have already been closed, but still in the
      connection list. When the worker is instructed to close the subflows
      that have been marked as closed, it might then try to close the initial
      subflow again.
      
       A consequence of that is that the SUB_CLOSED event can be seen twice:
      
        # ip mptcp endpoint
        1.1.1.1 id 1 subflow dev eth0
        2.2.2.2 id 2 subflow dev eth1
      
        # ip mptcp monitor &
        [         CREATED] remid=0 locid=0 saddr4=1.1.1.1 daddr4=9.9.9.9
        [     ESTABLISHED] remid=0 locid=0 saddr4=1.1.1.1 daddr4=9.9.9.9
        [  SF_ESTABLISHED] remid=0 locid=2 saddr4=2.2.2.2 daddr4=9.9.9.9
      
        # ip mptcp endpoint delete id 1
        [       SF_CLOSED] remid=0 locid=0 saddr4=1.1.1.1 daddr4=9.9.9.9
        [       SF_CLOSED] remid=0 locid=0 saddr4=1.1.1.1 daddr4=9.9.9.9
      
      The first one is coming from mptcp_pm_nl_rm_subflow_received(), and the
      second one from __mptcp_close_subflow().
      
      To avoid doing the post-closed processing twice, the subflow is now
      marked as closed the first time.
      
      Note that it is not enough to check if we are dealing with the first
      subflow and check its sk_state: the subflow might have been reset or
      closed before calling mptcp_close_ssk().

      mptcp: pm: fix ID 0 endp usage after multiple re-creations · 9366922a
      Matthieu Baerts (NGI0) authored
      'local_addr_used' and 'add_addr_accepted' are decremented for addresses
      not related to the initial subflow (ID0), because the source and
      destination addresses of the initial subflows are known from the
      beginning: they don't count as "additional local address being used" or
      "ADD_ADDR being accepted".
      
      It is then required not to increment them when the entrypoint used by
      the initial subflow is removed and re-added during a connection. Without
      this modification, this entrypoint cannot be removed and re-added more
      than once.

      It is possible to have in the list already closed subflows, e.g. the
      initial subflow has been already closed, but still in the list. No need
      to try to close it again, and increments the related counters again.

      selftests: mptcp: join: check re-adding init endp with != id · 1c2326fc
      Matthieu Baerts (NGI0) authored
      The initial subflow has a special local ID: 0. It is specific per
      connection.
      
      When a global endpoint is deleted and re-added later, it can have a
      different ID, but the kernel should still use the ID 0 if it corresponds
      to the initial address.
      
      This test validates this behaviour: the endpoint linked to the initial
      subflow is removed, and re-added with a different ID.
      
      Note that removing the initial subflow will not decrement the 'subflows'
      counters, which corresponds to the *additional* subflows. On the other
      hand, when the same endpoint is re-added, it will increment this
      counter, as it will be seen as an additional subflow this time.

      mptcp: pm: reset MPC endp ID when re-added · dce1c6d1
      Matthieu Baerts (NGI0) authored
      The initial subflow has a special local ID: 0. It is specific per
      connection.
      
      When a global endpoint is deleted and re-added later, it can have a
      different ID -- most services managing the endpoints automatically don't
      force the ID to be the same as before. It is then important to track
      these modifications to be consistent with the ID being used for the
      address used by the initial subflow, not to confuse the other peer or to
      send the ID 0 for the wrong address.
      
      Now when removing an endpoint, msk->mpc_endpoint_id is reset if it
      corresponds to this endpoint. When adding a new endpoint, the same
      variable is updated if the address match the one of the initial subflow.

      mptcp: pm: skip connecting to already established sf · bc19ff57
      Matthieu Baerts (NGI0) authored
      The lookup_subflow_by_daddr() helper checks if there is already a
      subflow connected to this address. But there could be a subflow that is
      closing, but taking time due to some reasons: latency, losses, data to
      process, etc.
      
      If an ADD_ADDR is received while the endpoint is being closed, it is
      better to try connecting to it, instead of rejecting it: the peer which
      has sent the ADD_ADDR will not be notified that the ADD_ADDR has been
      rejected for this reason, and the expected subflow will not be created
      at the end.
      
      This helper should then only look for subflows that are established, or
      going to be, but not the ones being closed.

      Matthieu Baerts (NGI0) authored
      Removing the endpoint linked to the initial subflow should trigger a
      RM_ADDR for the right ID, and the removal of the subflow. That's what is
      now being verified in the "delete and re-add" test.
      
      Note that removing the initial subflow will not decrement the 'subflows'
      counters, which corresponds to the *additional* subflows. On the other
      hand, when the same endpoint is re-added, it will increment this

      mptcp: pm: fix RM_ADDR ID for the initial subflow · 87b5896f
      Matthieu Baerts (NGI0) authored
      The initial subflow has a special local ID: 0. When an endpoint is being
      deleted, it is then important to check if its address is not linked to
      the initial subflow to send the right ID.
      
      If there was an endpoint linked to the initial subflow, msk's
      mpc_endpoint_id field will be set. We can then use this info when an
      endpoint is being removed to see if it is linked to the initial subflow.
      
      So now, the correct IDs are passed to mptcp_pm_nl_rm_addr_or_subflow(),
      it is no longer needed to use mptcp_local_id_match().

        The flags argument to getrandom() only has a behavioral effect on the
        function if the RNG isn't initialized yet, so vgetrandom() falls back
        to the syscall in that case. But if the RNG is initialized, all of the
        flags behave the same way, so vgetrandom() didn't bother checking
        them, and just ignored them entirely.
      
        But that doesn't account for invalid flags passed in, which need to be
        rejected so we can use them later"

      Typically, busy-polling durations are below 100 usec.
      
      When/if the busy-poller thread migrates to another cpu,
      local_clock() can be off by +/-2msec or more for small
      values of HZ, depending on the platform.
      
      Use ktimer_get_ns() to ensure deterministic behavior,
