      netdevsim: avoid potential loop in nsim_dev_trap_report_work() · ba5e1272

      Many syzbot reports include the following trace [1]
      
      If nsim_dev_trap_report_work() can not grab the mutex,
      it should rearm itself at least one jiffie later.

      net: Fix from address in memcpy_to_iter_csum() · fe92f874
      Michael Lass authored
      While inlining csum_and_memcpy() into memcpy_to_iter_csum(), the from
      address passed to csum_partial_copy_nocheck() was accidentally changed.
      This causes a regression in applications using UDP, as for example
      OpenAFS, causing loss of datagrams.

      Data Path Parity Errors for each channel in DMA unhandled at all, lead to

       "Including fixes from netfilter.
      
        As Paolo promised we continue to hammer out issues in our selftests.
        This is not the end but probably the peak.
      
        Current release - regressions:
      
         - smc: fix incorrect SMC-D link group matching logic
      
        Current release - new code bugs:
      
         - eth: bnxt: silence WARN() when device skips a timestamp, it happens
      
        Previous releases - regressions:
      
         - ipmr: fix null-deref when forwarding mcast packets
      
         - conntrack: evaluate window negotiation only for packets in the
           REPLY direction, otherwise SYN retransmissions trigger incorrect
           window scale negotiation
      
         - ipset: fix performance regression in swap operation
      
        Previous releases - always broken:
      
         - tcp: add sanity checks to types of pages getting into the rx
           zerocopy path, we only support basic NIC -> user, no page cache
           pages etc.
      
         - ip6_tunnel: make sure to pull inner header in __ip6_tnl_rcv()
      
         - nt_tables: more input sanitization changes
      
         - dsa: mt7530: fix 10M/100M speed on MediaTek MT7988 switch
      
         - bridge: mcast: fix loss of snooping after long uptime, jiffies do
           wrap on 32bit
      
         - xen-netback: properly sync TX responses, protect with locking
      
         - phy: mediatek-ge-soc: sync calibration values with MediaTek SDK,
           increase connection stability
      
         - eth: pds: fixes for various teardown, and reset races
      
        Misc:
      
         - hsr: silence WARN() if we can't alloc supervision frame, it

       "The current exception handler, which helps on kernel accesses to
        userspace, may exhibit data corruption. The problem is that it is not
        guaranteed that the compiler will use the processor register we
        specified in the source code, but may choose another register which
        then will lead to silent register- and data corruption. To fix this
        issue we now use another strategy to help the exception handler to
        always find and set the error code into the correct CPU register.
      
        The other fixes are small: fixing CPU hotplug bringup, fix the page
        alignment of the RO_DATA section, added a check for the calculated
        cache stride and fix possible hangups when printing longer output at
        bootup when running on serial console.

      IFLA_DPLL_PIN was added to rt_link messages but not to the spec, which
      breaks ynl. Add the missing definitions to the rt_link ynl spec.

      ====================
      Netfilter fixes for net
      
      1) TCP conntrack now only evaluates window negotiation for packets in
         the REPLY direction, from Ryan Schaefer. Otherwise SYN retransmissions
         trigger incorrect window scale negotiation. From Ryan Schaefer.
      
      2) Restrict tunnel objects to NFPROTO_NETDEV which is where it makes sense
         to use this object type.
      
      3) Fix conntrack pick up from the middle of SCTP_CID_SHUTDOWN_ACK packets.
         From Xin Long.
      
      4) Another attempt from Jozsef Kadlecsik to address the slow down of the
         swap command in ipset.
      
      5) Replace a BUG_ON by WARN_ON_ONCE in nf_log, and consolidate check for
         the case that the logger is NULL from the read side lock section.
      
      6) Address lack of sanitization for custom expectations. Restrict layer 3
         and 4 families to what it is supported by userspace.

      idpf: avoid compiler padding in virtchnl2_ptype struct · f0588b15
      Pavan Kumar Linga authored
      In the arm random config file, kconfig option 'CONFIG_AEABI' is
      disabled which results in adding the compiler flag '-mabi=apcs-gnu'.
      This causes the compiler to add padding in virtchnl2_ptype
      structure to align it to 8 bytes, resulting in the following
      size check failure:
      
      include/linux/build_bug.h:78:41: error: static assertion failed: "(6) == sizeof(struct virtchnl2_ptype)"
            78 | #define __static_assert(expr, msg, ...) _Static_assert(expr, msg)
               |                                         ^~~~~~~~~~~~~~
      include/linux/build_bug.h:77:34: note: in expansion of macro '__static_assert'
            77 | #define static_assert(expr, ...) __static_assert(expr, ##__VA_ARGS__, #expr)
               |                                  ^~~~~~~~~~~~~~~
      drivers/net/ethernet/intel/idpf/virtchnl2.h:26:9: note: in expansion of macro 'static_assert'
            26 |         static_assert((n) == sizeof(struct X))
               |         ^~~~~~~~~~~~~
      drivers/net/ethernet/intel/idpf/virtchnl2.h:982:1: note: in expansion of macro 'VIRTCHNL2_CHECK_STRUCT_LEN'
           982 | VIRTCHNL2_CHECK_STRUCT_LEN(6, virtchnl2_ptype);
               | ^~~~~~~~~~~~~~~~~~~~~~~~~~
      
      Avoid the compiler padding by using "__packed" structure
      attribute for the virtchnl2_ptype struct. Also align the
      structure by using "__aligned(2)" for better code optimization.
