      gve: Fix the queue page list allocated pages count · a95069ec
      Jeroen de Borst authored
      In gve_alloc_queue_page_list(), when a page allocation fails,
      qpl->num_entries will be wrong.  In this case priv->num_registered_pages
      can underflow in gve_free_queue_page_list(), causing subsequent calls
      to gve_alloc_queue_page_list() to fail.

      openvswitch: fix flow command message size · 4e81c0b3
      Paolo Abeni authored
      When user-space sets the OVS_UFID_F_OMIT_* flags, and the relevant
      flow has no UFID, we can exceed the computed size, as
      ovs_nla_put_identifier() will always dump an OVS_FLOW_ATTR_KEY
      attribute.
      Take the above in account when computing the flow command message
      size.

      net: psample: fix skb_over_panic · 7eb9d767
      Nikolay Aleksandrov authored
      We need to calculate the skb size correctly otherwise we risk triggering
      skb_over_panic[1]. The issue is that data_len is added to the skb in a
      nl attribute, but we don't account for its header size (nlattr 4 bytes)
      and alignment. We account for it when calculating the total size in
      the > PSAMPLE_MAX_PACKET_SIZE comparison correctly, but not when
      allocating after that. The fix is simple - use nla_total_size() for
      data_len when allocating.
      
      To reproduce:
       $ tc qdisc add dev eth1 clsact
       $ tc filter add dev eth1 egress matchall action sample rate 1 group 1 trunc 129
       $ mausezahn eth1 -b bcast -a rand -c 1 -p 129
       < skb_over_panic BUG(), tail is 4 bytes past skb->end >

      net: port < inet_prot_sock(net) --> inet_port_requires_bind_service(net, port) · 82f31ebf
      Maciej Żenczykowski authored
      Note that the sysctl write accessor functions guarantee that:
        net->ipv4.sysctl_ip_prot_sock <= net->ipv4.ip_local_ports.range[0]
      invariant is maintained, and as such the max() in selinux hooks is actually spurious.
      
      ie. even though
        if (snum < max(inet_prot_sock(sock_net(sk)), low) || snum > high) {
      per logic is the same as
        if ((snum < inet_prot_sock(sock_net(sk)) && snum < low) || snum > high) {
      it is actually functionally equivalent to:
        if (snum < low || snum > high) {
      which is equivalent to:
        if (snum < inet_prot_sock(sock_net(sk)) || snum < low || snum > high) {
      even though the first clause is spurious.
      
      But we want to hold on to it in case we ever want to change what what
      inet_port_requires_bind_service() means (for example by changing
      it from a, by default, [0..1024) range to some sort of set).

      ====================
      ibmvnic: Harden device commands and queries
      
      This patch series fixes some shortcomings with the current
      VNIC device command implementation. The first patch fixes
      the initialization of driver completion structures used
      for device commands. Additionally, all waits for device
      commands are bounded with a timeout in the event that the
      device does not respond or becomes inoperable. Finally,
      serialize queries to retain the integrity of device return
      codes.
      
      Changes in v2:
      
       - included header comment for ibmvnic_wait_for_completion
       - removed open-coded loop in patch 3/4, suggested by Jakub
       - ibmvnic_wait_for_completion accepts timeout value in milliseconds
         instead of jiffies
       - timeout calculations cleaned up and completed before wait loop
       - included missing mutex_destroy calls, suggested by Jakub
       - included comment before mutex declaration

       "Lots of stuff going on in the core for SPI this time around, the two
        big changes both being around time in different forms:
      
         - A rework of delay times from Alexandru Ardelean which makes the
           ways in which they are specified more consistent between drivers so
           that what's available to clients is less dependent on the hardware
           implementation.
      
         - Support for PTP timestamping of transfers from Vladimir Oltean,
           useful for use with precision clocks with SPI control interfaces.

       - A pidfd's fdinfo file currently contains the field "Pid:\t<pid>"
         where <pid> is the pid of the process in the pid namespace of the
         procfs instance the fdinfo file for the pidfd was opened in.
      
         The fdinfo file has now gained a new "NSpid:\t<ns-pid1>[\t<ns-pid2>[...]]"
         field which lists the pids of the process in all child pid namespaces
         provided the pid namespace of the procfs instance it is looked up
         under has an ancestoral relationship with the pid namespace of the
         process. If it does not 0 will be shown and no further pid namespaces
         will be listed. Tests included. (Christian Kellner)

         the Pid and NSpid fields in the pidfd's fdinfo file. Tests included.

       - Add CLONE_CLEAR_SIGHAND. This lets callers clear all signal handler
         that are not SIG_DFL or SIG_IGN at process creation time. This
         originated as a feature request from glibc to improve performance and
         elimate races in their posix_spawn() implementation. Tests included.

       - Add support for choosing a specific pid for a process with clone3().
         This is the feature which was part of the thread update for v5.4 but
         after a discussion at LPC in Lisbon we decided to delay it for one
         more cycle in order to make the interface more generic. This has now
         done. It is now possible to choose a specific pid in a whole pid
         namespaces (sub)hierarchy instead of just one pid namespace. In order
         to choose a specific pid the caller must have CAP_SYS_ADMIN in all
         owning user namespaces of the target pid namespaces. Tests included.

       "A lot of changes this time around, details below.
      
        From the next cycle onwards, we'll switch the EDAC tree to topic
        branches (instead of a single edac-for-next branch) which should make
        the changes handling more flexible, hopefully. We'll see.
      
        Summary:
      
         - Rework error logging functions to accept a count of errors
           parameter (Hanna Hawa)

       "The main MIPS changes for 5.5:
      
         - Atomics-related code sees some rework & cleanup, most notably
           allowing Loongson LL/SC errata workarounds to be more bulletproof &
           their correctness to be checked at build time.
      
         - Command line setup code is simplified somewhat, resolving various
           corner cases.
      
         - MIPS kernels can now be built with kcov code coverage support.
      
         - We can now build with CONFIG_FORTIFY_SOURCE=y.
      
         - Miscellaneous cleanups.
      
        And some platform specific changes:
      
         - We now disable some broken TLB functionality on certain Ingenic
           systems, and JZ4780 systems gain some devicetree nodes to support
           more devices.
      
         - Loongson support sees a number of cleanups, and we gain initial
           support for Loongson 3A R4 systems.
      
         - We gain support for MediaTek MT7688-based GARDENA Smart Gateway
           systems.
