      net: stmmac: fix incorrect DMA channel intr enable setting of EQoS v4.10 · 879c348c
      Ong Boon Leong authored
      We introduce dwmac410_dma_init_channel() here for both EQoS v4.10 and
      above which use different DMA_CH(n)_Interrupt_Enable bit definitions for
      NIE and AIE.

      ibmvnic: Fix possibly uninitialized old_num_tx_queues variable warning. · 6881b07f
      Michal Suchanek authored
      GCC 7.5 reports:
      ../drivers/net/ethernet/ibm/ibmvnic.c: In function 'ibmvnic_reset_init':
      ../drivers/net/ethernet/ibm/ibmvnic.c:5373:51: warning: 'old_num_tx_queues' may be used uninitialized in this function [-Wmaybe-uninitialized]
      ../drivers/net/ethernet/ibm/ibmvnic.c:5373:6: warning: 'old_num_rx_queues' may be used uninitialized in this function [-Wmaybe-uninitialized]
      
      The variable is initialized only if(reset) and used only if(reset &&
      something) so this is a false positive. However, there is no reason to
      not initialize the variables unconditionally avoiding the warning.

      Dan Carpenter authored
      The value of "lmac_id" can be controlled by the user and if it is larger
      then the number of bits in long then it reads outside the bitmap.
      The highest valid value is less than MAX_LMAC_PER_CGX (4).

      iwlwifi: don't call netif_napi_add() with rxq->lock held (was Re: Lockdep warning in iwl_pcie_rx_handle())
      
      We can't call netif_napi_add() with rxq-lock held, as there is a potential
      for deadlock as spotted by lockdep (see below). rxq->lock is not
      protecting anything over the netif_napi_add() codepath anyway, so let's
      drop it just before calling into NAPI.

       but this lock took another, SOFTIRQ-unsafe lock in the past:
        (napi_hash_lock){+.+.}-{2:2}
      
       and interrupts could create inverse lock ordering between them.
      
       other info that might help us debug this:

      tcp: add sanity tests to TCP_QUEUE_SEQ · 8811f4a9
      Eric Dumazet authored
      Qingyu Li reported a syzkaller bug where the repro
      changes RCV SEQ _after_ restoring data in the receive queue.

      recvfrom(3, NULL, 20, 0, NULL, NULL)    = -1 ECONNRESET (Connection reset by peer)
      
      syslog shows:

      This should not be allowed. TCP_QUEUE_SEQ should only be used
      when queues are empty.
      
      This patch fixes this case, and the tx path as well.

      hv_netvsc: Fix validation in netvsc_linkstatus_callback() · 3946688e
      Andrea Parri (Microsoft) authored
      Contrary to the RNDIS protocol specification, certain (pre-Fe)
      implementations of Hyper-V's vSwitch did not account for the status
      buffer field in the length of an RNDIS packet; the bug was fixed in
      newer implementations.  Validate the status buffer fields using the
      length of the 'vmtransfer_page' packet (all implementations), that
      is known/validated to be less than or equal to the receive section
      size and not smaller than the length of the RNDIS message.

      net: expand textsearch ts_state to fit skb_seq_state · b228c9b0
      Willem de Bruijn authored
      The referenced commit expands the skb_seq_state used by
      skb_find_text with a 4B frag_off field, growing it to 48B.
      
      This exceeds container ts_state->cb, causing a stack corruption:
      
      [   73.238353] Kernel panic - not syncing: stack-protector: Kernel stack
      is corrupted in: skb_find_text+0xc5/0xd0

      [   73.252613] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996),
      BIOS 1.14.0-2 04/01/2014
      [   73.260078] Call Trace:

      The struct is passed between skb_find_text and its callbacks
      skb_prepare_seq_read, skb_seq_read and skb_abort_seq read through
      the textsearch interface using TS_SKB_CB.
      
      I assumed that this mapped to skb->cb like other .._SKB_CB wrappers.
      skb->cb is 48B. But it maps to ts_state->cb, which is only 40B.
      
      skb->cb was increased from 40B to 48B after ts_state was introduced,
      in commit 3e3850e9 ("[NETFILTER]: Fix xfrm lookup in
      ip_route_me_harder/ip6_route_me_harder").
      
      Increase ts_state.cb[] to 48 to fit the struct.
      
      Also add a BUILD_BUG_ON to avoid a repeat.
      
      The alternative is to directly add a dependency from textsearch onto
      linux/skbuff.h, but I think the intent is textsearch to have no such
      dependencies on its callers.
