      x86/ptrace: Fix xfpregs_set()'s incorrect xmm clearing · 44cad52c
      Andy Lutomirski authored
      xfpregs_set() handles 32-bit REGSET_XFP and 64-bit REGSET_FP. The actual
      code treats these regsets as modern FX state (i.e. the beginning part of
      XSTATE). The declarations of the regsets thought they were the legacy
      i387 format. The code thought they were the 32-bit (no xmm8..15) variant
      of XSTATE and, for good measure, made the high bits disappear by zeroing
      the wrong part of the buffer. The latter broke ptrace, and everything
      else confused anyone trying to understand the code. In particular, the
      nonsense definitions of the regsets confused me when I wrote this code.
      
      Clean this all up. Change the declarations to match reality (which
      shouldn't change the generated code, let alone the ABI) and fix
      xfpregs_set() to clear the correct bits and to only do so for 32-bit
      callers.

      bonding: force carrier update when releasing slave · a6ab75ce
      Zhang Changzhong authored
      In __bond_release_one(), bond_set_carrier() is only called when bond
      device has no slave. Therefore, if we remove the up slave from a master
      with two slaves and keep the down slave, the master will remain up.
      
      Fix this by moving bond_set_carrier() out of if (!bond_has_slaves(bond))
      statement.
      
      Reproducer:
      $ insmod bonding.ko mode=0 miimon=100 max_bonds=2
      $ ifconfig bond0 up
      $ ifenslave bond0 eth0 eth1
      $ ifconfig eth0 down
      $ ifenslave -d bond0 eth1
      $ cat /proc/net/bonding/bond0

      x86/sgx: Fix missing poison handling in reclaimer · e5733d8c
      Reinette Chatre authored
      The SGX reclaimer code lacks page poison handling in its main
      free path. This can lead to avoidable machine checks if a
      poisoned page is freed and reallocated instead of being
      isolated.
      
      A troublesome scenario is:
       1. Machine check (#MC) occurs (asynchronous, !MF_ACTION_REQUIRED)
       2. arch_memory_failure() is eventually called
       3. (SGX) page->poison set to 1
       4. Page is reclaimed
       5. Page added to normal free lists by sgx_reclaim_pages()
          ^ This is the bug (poison pages should be isolated on the
          sgx_poison_page_list instead)
       6. Page is reallocated by some innocent enclave, a second (synchronous)
          in-kernel #MC is induced, probably during EADD instruction.
          ^ This is the fallout from the bug
      
      (6) is unfortunate and can be avoided by replacing the open coded
      enclave page freeing code in the reclaimer with sgx_free_epc_page()
      to obtain support for poison page handling that includes placing the
      poisoned page on the correct list.
      
      Fixes: d6d261bd ("x86/sgx: Add new sgx_epc_page flag bit to mark free pages")
