      bpf: restore behavior of bpf_map_update_elem · a6ed3ea6
      Alexei Starovoitov authored
      The introduction of pre-allocated hash elements inadvertently broke
      the behavior of bpf hash maps where users expected to call
      bpf_map_update_elem() without considering that the map can be full.
      Some programs do:
      old_value = bpf_map_lookup_elem(map, key);
      if (old_value) {
        ... prepare new_value on stack ...
        bpf_map_update_elem(map, key, new_value);
      Before pre-alloc the update() for existing element would work even
      in 'map full' condition. Restore this behavior.
      The above program could have updated old_value in place instead of
      update() which would be faster and most programs use that approach,
      but sometimes the values are large and the programs use update()
      helper to do atomic replacement of the element.
      Note we cannot simply update element's value in-place like percpu
      hash map does and have to allocate extra num_possible_cpu elements
      and use this extra reserve when the map is full.

      rxrpc: Fix races between skb free, ACK generation and replying · 372ee163
      David Howells authored
      Inside the kafs filesystem it is possible to occasionally have a call
      processed and terminated before we've had a chance to check whether we need
      to clean up the rx queue for that call because afs_send_simple_reply() ends
      the call when it is done, but this is done in a workqueue item that might
      happen to run to completion before afs_deliver_to_call() completes.
      Further, it is possible for rxrpc_kernel_send_data() to be called to send a
      reply before the last request-phase data skb is released.  The rxrpc skb
      destructor is where the ACK processing is done and the call state is
      advanced upon release of the last skb.  ACK generation is also deferred to
      a work item because it's possible that the skb destructor is not called in
      a context where kernel_sendmsg() can be invoked.
      To this end, the following changes are made:
       (1) kernel_rxrpc_data_consumed() is added.  This should be called whenever
           an skb is emptied so as to crank the ACK and call states.  This does
           not release the skb, however.  kernel_rxrpc_free_skb() must now be
           called to achieve that.  These together replace
       (2) kernel_rxrpc_data_consumed() is wrapped by afs_data_consumed().
           This makes afs_deliver_to_call() easier to work as the skb can simply
           be discarded unconditionally here without trying to work out what the
           return value of the ->deliver() function means.
           The ->deliver() functions can, via afs_data_complete(),
           afs_transfer_reply() and afs_extract_data() mark that an skb has been
           consumed (thereby cranking the state) without the need to
           conditionally free the skb to make sure the state is correct on an
           incoming call for when the call processor tries to send the reply.
       (3) rxrpc_recvmsg() now has to call kernel_rxrpc_data_consumed() when it
           has finished with a packet and MSG_PEEK isn't set.
       (4) rxrpc_packet_destructor() no longer calls rxrpc_hard_ACK_data().
           Because of this, we no longer need to clear the destructor and put the
           call before we free the skb in cases where we don't want the ACK/call
           state to be cranked.
       (5) The ->deliver() call-type callbacks are made to return -EAGAIN rather
           than 0 if they expect more data (afs_extract_data() returns -EAGAIN to
           the delivery function already), and the caller is now responsible for
           producing an abort if that was the last packet.
       (6) There are many bits of unmarshalling code where:
       		ret = afs_extract_data(call, skb, last, ...);
      		switch (ret) {
      		case 0:		break;
      		case -EAGAIN:	return 0;
      		default:	return ret;
           is to be found.  As -EAGAIN can now be passed back to the caller, we
           now just return if ret < 0:
       		ret = afs_extract_data(call, skb, last, ...);
      		if (ret < 0)
      			return ret;
       (7) Checks for trailing data and empty final data packets has been
           consolidated as afs_data_complete().  So:
      		if (skb->len > 0)
      			return -EBADMSG;
      		if (!last)
      			return 0;
      		ret = afs_data_complete(call, skb, last);
      		if (ret < 0)
      			return ret;
       (8) afs_transfer_reply() now checks the amount of data it has against the
           amount of data desired and the amount of data in the skb and returns
           an error to induce an abort if we don't get exactly what we want.
      Without these changes, the following oops can occasionally be observed,
      particularly if some printks are inserted into the delivery path:

      OVS: Ignore negative headroom value · 5ef9f289
      Ian Wienand authored
      net_device->ndo_set_rx_headroom (introduced in
      871b642a) says
        "Setting a negtaive value reset the rx headroom
         to the default value".
      It seems that the OVS implementation in
      3a927bc7 overlooked this and sets
      dev->needed_headroom unconditionally.
      This doesn't have an immediate effect, but can mess up later
      LL_RESERVED_SPACE calculations, such as done in
      net/ipv6/mcast.c:mld_newpack.  For reference, this issue was found
      from a skb_panic raised there after the length calculations had given
      the wrong result.
      Note the other current users of this interface
      (drivers/net/tun.c:tun_set_headroom and
      drivers/net/veth.c:veth_set_rx_headroom) are both checking this
      correctly thus need no modification.
      Thanks to Ben for some pointers from the crash dumps!

      qlcnic: fix data structure corruption in async mbx command handling · 2b10d3ec
      Manish Chopra authored
      This patch fixes a data structure corruption bug in the SRIOV VF mailbox
      handler code. While handling mailbox commands from the atomic context,
      driver is accessing and updating qlcnic_async_work_list_struct entry fields
      in the async work list. These fields could be concurrently accessed by the
      work function resulting in data corruption.
      This patch restructures async mbx command handling by using a separate
      async command list instead of using a list of work_struct structures.
      A single work_struct is used to schedule and handle the async commands
      with proper locking mechanism.

      bpf: fix method of PTR_TO_PACKET reg id generation · 1f415a74
      Jakub Kicinski authored
      Using per-register incrementing ID can lead to
      find_good_pkt_pointers() confusing registers which
      have completely different values.  Consider example:
      0: (bf) r6 = r1
      1: (61) r8 = *(u32 *)(r6 +76)
      2: (61) r0 = *(u32 *)(r6 +80)
      3: (bf) r7 = r8
      4: (07) r8 += 32
      5: (2d) if r8 > r0 goto pc+9
       R0=pkt_end R1=ctx R6=ctx R7=pkt(id=0,off=0,r=32) R8=pkt(id=0,off=32,r=32) R10=fp
      6: (bf) r8 = r7
      7: (bf) r9 = r7
      8: (71) r1 = *(u8 *)(r7 +0)
      9: (0f) r8 += r1
      10: (71) r1 = *(u8 *)(r7 +1)
      11: (0f) r9 += r1
      12: (07) r8 += 32
      13: (2d) if r8 > r0 goto pc+1
       R0=pkt_end R1=inv56 R6=ctx R7=pkt(id=0,off=0,r=32) R8=pkt(id=1,off=32,r=32) R9=pkt(id=1,off=0,r=32) R10=fp
      14: (71) r1 = *(u8 *)(r9 +16)
      15: (b7) r7 = 0
      16: (bf) r0 = r7
      17: (95) exit
      We need to get a UNKNOWN_VALUE with imm to force id
      generation so lines 0-5 make r7 a valid packet pointer.
      We then read two different bytes from the packet and
      add them to copies of the constructed packet pointer.
      r8 (line 9) and r9 (line 11) will get the same id of 1,
      independently.  When either of them is validated (line
      13) - find_good_pkt_pointers() will also mark the other
      as safe.  This leads to access on line 14 being mistakenly
      considered safe.
      Fixes: 969bf05e ("bpf: direct packet access")

      net: xgene: fix maybe-uninitialized variable · ea966cb6
      Arnd Bergmann authored
      Building with -Wmaybe-uninitialized shows a potential use of
      an uninitialized variable:
      drivers/net/ethernet/apm/xgene/xgene_enet_hw.c: In function 'xgene_enet_phy_connect':
      drivers/net/ethernet/apm/xgene/xgene_enet_hw.c:802:23: warning: 'phy_dev' may be used uninitialized in this function [-Wmaybe-uninitialized]
      Although the compiler correctly identified this based on the function,
      the current code is still safe as long dev->of_node is non-NULL
      for the case of CONFIG_ACPI=n, which is currently the case.
      The warning is now disabled by default, but still appears when
      building with W=1, and other build test tools should be able to
      detect it as well. Adding an #else clause here makes the code
      more robust and makes it clear to the compiler that this cannot

      openvswitch: Remove incorrect WARN_ONCE(). · bce91f8a
      Jarno Rajahalme authored
      ovs_ct_find_existing() issues a warning if an existing conntrack entry
      classified as IP_CT_NEW is found, with the premise that this should
      not happen.  However, a newly confirmed, non-expected conntrack entry
      remains IP_CT_NEW as long as no reply direction traffic is seen.  This
      has resulted into somewhat confusing kernel log messages.  This patch
      removes this check and warning.
      Fixes: 289f2253 ("openvswitch: Find existing conntrack entry after upcall.")
