      fs: dlm: don't use deprecated timeout features by default · 6b0afc0c
      Alexander Aring authored
      This patch will disable use of deprecated timeout features if
      CONFIG_DLM_DEPRECATED_API is not set.  The deprecated features
      will be removed in upcoming kernel release v6.2.

      fs: dlm: add deprecation Kconfig and warnings for timeouts · 81eeb82f
      Alexander Aring authored
      This patch adds a CONFIG_DLM_DEPRECATED_API Kconfig option
      that must be enabled to use two timeout-related features
      that we intend to remove in kernel v6.2.  Warnings are
      printed if either is enabled and used.  Neither has ever
      been used as far as we know.
      
      . The DLM_LSFL_TIMEWARN lockspace creation flag will be
        removed, along with the associated configfs entry for
        setting the timeout.  Setting the flag and configfs file
        would cause dlm to track how long locks were waiting
        for reply messages.  After a timeout, a kernel message
        would be logged, and a netlink message would be sent
        to userspace.  Recently, midcomms messages have been
        added that produce much better logging about actual
        problems with messages.  No use has ever been found
        for the netlink messages.
      
      . The userspace libdlm API has allowed the DLM_LKF_TIMEOUT
        flag with a timeout value to be set in lock requests.
        The lock request would be cancelled after the timeout.

        lockdep invokes prandom_u32() to create cookies. This worked until

        spinlock for extraction, which does not work on RT when invoked from

      x86/tdx: Handle load_unaligned_zeropad() page-cross to a shared page · 1e776965
      Kirill A. Shutemov authored
      load_unaligned_zeropad() can lead to unwanted loads across page boundaries.
      The unwanted loads are typically harmless. But, they might be made to
      totally unrelated or even unmapped memory. load_unaligned_zeropad()
      relies on exception fixup (#PF, #GP and now #VE) to recover from these
      unwanted loads.
      
      In TDX guests, the second page can be shared page and a VMM may configure
      it to trigger #VE.
      
      The kernel assumes that #VE on a shared page is an MMIO access and tries to
      decode instruction to handle it. In case of load_unaligned_zeropad() it
      may result in confusion as it is not MMIO access.
      
      Fix it by detecting split page MMIO accesses and failing them.
      load_unaligned_zeropad() will recover using exception fixups.
      
      The issue was discovered by analysis and reproduced artificially. It was
      not triggered during testing.
