      x86: Deprecate a.out support · eac61655
      Borislav Petkov authored
      Linux supports ELF binaries for ~25 years now.  a.out coredumping has
      bitrotten quite significantly and would need some fixing to get it into
      shape again but considering how even the toolchains cannot create a.out
      executables in its default configuration, let's deprecate a.out support
      and remove it a couple of releases later, instead.

      a.out: remove core dumping support · 08300f44
      Linus Torvalds authored
      We're (finally) phasing out a.out support for good.  As Borislav Petkov
      points out, we've supported ELF binaries for about 25 years by now, and
      coredumping in particular has bitrotted over the years.
      
      None of the tool chains even support generating a.out binaries any more,
      and the plan is to deprecate a.out support entirely for the kernel.  But
      I want to start with just removing the core dumping code, because I can
      still imagine that somebody actually might want to support a.out as a
      simpler biinary format.
      
      Particularly if you generate some random binaries on the fly, ELF is a
      much more complicated format (admittedly ELF also does have a lot of
      toolchain support, mitigating that complexity a lot and you really
      should have moved over in the last 25 years).
      
      So it's at least somewhat possible that somebody out there has some
      workflow that still involves generating and running a.out executables.
      
      In contrast, it's very unlikely that anybody depends on debugging any
      legacy a.out core files.  But regardless, I want this phase-out to be
      done in two steps, so that we can resurrect a.out support (if needed)
      without having to resurrect the core file dumping that is almost
      certainly not needed.
      
      Jann Horn pointed to the <asm/a.out-core.h> file that my first trivial
      cut at this had missed.
      
      And Alan Cox points out that the a.out binary loader _could_ be done in
      user space if somebody wants to, but we might keep just the loader in
      the kernel if somebody really wants it, since the loader isn't that big
      and has no really odd special cases like the core dumping does.

      fs: Make splice() and tee() take into account O_NONBLOCK flag on pipes · ee5e0011
      Slavomir Kaslev authored
      The current implementation of splice() and tee() ignores O_NONBLOCK set
      on pipe file descriptors and checks only the SPLICE_F_NONBLOCK flag for
      blocking on pipe arguments.  This is inconsistent since splice()-ing
      from/to non-pipe file descriptors does take O_NONBLOCK into
      consideration.
      
      Fix this by promoting O_NONBLOCK, when set on a pipe, to
      SPLICE_F_NONBLOCK.
      
      Some context for how the current implementation of splice() leads to
      inconsistent behavior.  In the ongoing work[1] to add VM tracing
      capability to trace-cmd we stream tracing data over named FIFOs or
      vsockets from guests back to the host.
      
      When we receive SIGINT from user to stop tracing, we set O_NONBLOCK on
      the input file descriptor and set SPLICE_F_NONBLOCK for the next call to
      splice().  If splice() was blocked waiting on data from the input FIFO,
      after SIGINT splice() restarts with the same arguments (no
      SPLICE_F_NONBLOCK) and blocks again instead of returning -EAGAIN when no
      data is available.
      
      This differs from the splice() behavior when reading from a vsocket or
      when we're doing a traditional read()/write() loop (trace-cmd's
      --nosplice argument).
      
      With this patch applied we get the same behavior in all situations after
      setting O_NONBLOCK which also matches the behavior of doing a
      read()/write() loop instead of splice().
      
      This change does have potential of breaking users who don't expect
      EAGAIN from splice() when SPLICE_F_NONBLOCK is not set.  OTOH programs
      that set O_NONBLOCK and don't anticipate EAGAIN are arguably buggy[2].
