      bpf, lsm: Fix the file_mprotect LSM test. · 5222d696
      KP Singh authored
      The test was previously using an mprotect on the heap memory allocated
      using malloc and was expecting the allocation to be always using
      sbrk(2). This is, however, not always true and in certain conditions
      malloc may end up using anonymous mmaps for heap alloctions. This means
      that the following condition that is used in the "lsm/file_mprotect"
      program is not sufficent to detect all mprotect calls done on heap
      memory:
      
      	is_heap = (vma->vm_start >= vma->vm_mm->start_brk &&
      		   vma->vm_end <= vma->vm_mm->brk);
      
      The test is updated to use an mprotect on memory allocated on the stack.
      While this would result in the splitting of the vma, this happens only
      after the security_file_mprotect hook. So, the condition used in the BPF
      program holds true.

      cxgb4: fix MPS index overwrite when setting MAC address · 41aa8561
      Herat Ramani authored
      cxgb4_update_mac_filt() earlier requests firmware to add a new MAC
      address into MPS TCAM. The MPS TCAM index returned by firmware is
      stored in pi->xact_addr_filt. However, the saved MPS TCAM index gets
      overwritten again with the return value of cxgb4_update_mac_filt(),
      which is wrong.
      
      When trying to update to another MAC address later, the wrong MPS TCAM
      index is sent to firmware, which causes firmware to return error,
      because it's not the same MPS TCAM index that firmware had sent
      earlier to driver.
      
      So, fix by removing the wrong overwrite being done after call to
      cxgb4_update_mac_filt().

      Looks like addrconf_sysctl_addr_gen_mode() bypasses the original "is
      this a slave interface?" check added by commit c2edacf8, and
      results in an address getting added, while w/the proposed patch added,
      no address gets added. This simply adds the same gating check to another
      code path, and thus should prevent the same devices from erroneously
      obtaining an ipv6 link-local address.

      net_sched: add a temporary refcnt for struct tcindex_data · 304e0242
      Cong Wang authored
      Although we intentionally use an ordered workqueue for all tc
      filter works, the ordering is not guaranteed by RCU work,
      given that tcf_queue_work() is esstenially a call_rcu().
      
      This problem is demostrated by Thomas:
      
        CPU 0:
          tcf_queue_work()
            tcf_queue_work(&r->rwork, tcindex_destroy_rexts_work);
      
        -> Migration to CPU 1
      
        CPU 1:
           tcf_queue_work(&p->rwork, tcindex_destroy_work);
      
      so the 2nd work could be queued before the 1st one, which leads
      to a free-after-free.
      
      Enforcing this order in RCU work is hard as it requires to change
      RCU code too. Fortunately we can workaround this problem in tcindex
      filter by taking a temporary refcnt, we only refcnt it right before
      we begin to destroy it. This simplifies the code a lot as a full
      refcnt requires much more changes in tcindex_set_parms().

      Pull SELinux updates from Paul Moore:
       "We've got twenty SELinux patches for the v5.7 merge window, the
        highlights are below:
      
         - Deprecate setting /sys/fs/selinux/checkreqprot to 1.
      
           This flag was originally created to deal with legacy userspace and
           the READ_IMPLIES_EXEC personality flag. We changed the default from
           1 to 0 back in Linux v4.4 and now we are taking the next step of
           deprecating it, at some point in the future we will take the final
           step of rejecting 1.
      
         - Allow kernfs symlinks to inherit the SELinux label of the parent
           directory. In order to preserve backwards compatibility this is
           protected by the genfs_seclabel_symlinks SELinux policy capability.
      
         - Optimize how we store filename transitions in the kernel, resulting
           in some significant improvements to policy load times.
      
         - Do a better job calculating our internal hash table sizes which
           resulted in additional policy load improvements and likely general
           SELinux performance improvements as well.
      
         - Remove the unused initial SIDs (labels) and improve how we handle
           initial SIDs.
      
         - Enable per-file labeling for the bpf filesystem.
      
         - Ensure that we properly label NFS v4.2 filesystems to avoid a
           temporary unlabeled condition.
      
         - Add some missing XFS quota command types to the SELinux quota
           access controls.
      
         - Fix a problem where we were not updating the seq_file position
           index correctly in selinuxfs.
      
         - We consolidate some duplicated code into helper functions.
      
         - A number of list to array conversions.
      
         - Update Stephen Smalley's email address in MAINTAINERS"
