      qemu-char: (Re-)connect for tcp_chr_write() unconnected writing · c3767ed0
      Lei Li authored
      
      
      tcp_chr_write() did not deal with writing to an unconnected
      connection and return the original length of the data, it's
      not right and would cause false writing. So (re-)connect it
      and return 0 for this situation.

      Allow QEMUMachine to override reset sequencing · be522029
      David Gibson authored
      
      
      qemu_system_reset() function always performs the same basic actions on
      all machines.  This includes running all the reset handler hooks,
      however the order in which these will run is not always easily predictable.
      
      This patch splits the core of qemu_system_reset() - the invocation of
      the reset handlers - out into a new qemu_devices_reset() function.
      qemu_system_reset() will usually call qemu_devices_reset(), but that
      can be now overriden by a new reset method in the QEMUMachine
      structure.
      
      Individual machines can use this reset method, if necessary, to
      perform any extra, machine specific initializations which have to
      occur before or after the bulk of the reset handlers.  It's expected
      that the method will call qemu_devices_reset() at some point, but if
      the machine has really strange ordering requirements between devices
      resets it could even override that with it's own reset sequence (with
      great care, obviously).
      
      For a specific example of when this might be needed: a number of
      machines (but not PC) load images specified with -kernel or -initrd
      directly into the machine RAM before booting the guest.  This mostly
      works at the moment, but to make this actually safe requires that this
      load occurs after peripheral devices are reset - otherwise they could
      have active DMAs in progress which would clobber the in memory images.
      Some machines (notably pseries) also have other entry conditions which
      need to be set up as the last thing before executing in guest space -
      some of this could be considered "emulated firmware" in the sense that
      the actions of the firmware are emulated directly by qemu rather than
      by executing a firmware image within the guest.  When the platform's
      firmware to OS interface is sufficiently well specified, this saves
      time both in implementing the "firmware" and executing it.

      pseries: Instantiate USB interface when required · 35139a59
      David Gibson authored
      
      
      The pseries machine already supports the -vga std option, creating a
      graphics adapter.  However, this is not very useful without being able to
      add a keyboard and mouse as well.  This patch addresses this by adding
      a USB interface when requested, and automatically adding a USB keyboard
      and mouse when VGA is enabled.
      
      This is a stop gap measure to get usable graphics mode on pseries while
      waiting for Li Zhang's rework of USB options to go in after 1.2.

      v1:
       - I added a syscall struct using priority levels as described in the
         libseccomp man page. The priority numbers are based to the frequency
         they appear in a sample strace from a regular qemu guest run under
         libvirt.
      
         Libseccomp generates linear BPF code to filter system calls, those rules
         are read one after another. The priority system places the most common
         rules first in order to reduce the overhead when processing them.
      
      v1 -> v2:
       - Fixed some style issues
       - Removed code from vl.c and created qemu-seccomp.[ch]
       - Now using ARRAY_SIZE macro
       - Added more syscalls without priority/frequency set yet
      
      v2 -> v3:
       - Adding copyright and license information
       - Replacing seccomp_whitelist_count just by ARRAY_SIZE
       - Adding header protection to qemu-seccomp.h
       - Moving QemuSeccompSyscall definition to qemu-seccomp.c
       - Negative return from seccomp_start is fatal now.
       - Adding open() and execve() to the whitelis
      
      v3 -> v4:
       - Tests revealed a bigger set of syscalls.
       - seccomp_start() now has an argument to set the mode according to the
         configure option trap or kill.
      
      v4 -> v5:
       - Tests on x86_64 required a new specific set of system calls.
       - libseccomp release 1.0.0: part of the API have changed in this last
         release, had to adapt to the new function signatures.

      memory: add -machine dump-guest-core=on|off · ddb97f1d
      Jason Baron authored
      
      
      Add a new '[,dump-guest-core=on|off]' option to the '-machine' option. When
      'dump-guest-core=off' is specified, guest memory is omitted from the core dump.
      The default behavior continues to be to include guest memory when a core dump is
      triggered. In my testing, this brought the core dump size down from 384MB to 6MB
      on a 2GB guest.
      
      Is anything additional required to preserve this setting for migration or
      savevm? I don't believe so.
      
      Changelog:
      v3:
          Eliminate globals as per Anthony's suggestion
          set no dump from qemu_ram_remap() as well
      v2:

      Support using a different compiler for Objective-C files · 3c4a4d0d
      Peter Maydell authored
      
      
      MacOSX 10.8 ("Mountain Lion") requires us to compile our one
      Objective-C source file with clang even if the rest of QEMU
      requires a real gcc, because the system headers we use make
      use of Apple's "Blocks" extension to C/ObjC, and mainline
      gcc doesn't support that. Since we only need to use a true
      gcc for the parts of QEMU that use the fixed-register
      env variable, we can simply use clang to build the ObjC
      file: it will link to the gcc-built objects with no problems.
      
      Add the necessary support for an OBJCC variable in the
      makefile and configure machinery; we default to clang
      if we have it, otherwise whatever CC is (since gcc
      might be the Apple gcc which does support Blocks).

      configure: Define OS_OBJECT_USE_OBJC=0 for MacOSX builds · a0b7cf6b
      Peter Maydell authored
      
      
      MacOSX 10.8 ("Mountain Lion") defaults to trying to use automated
      reference counting on certain objects.  This means that the system
      header files will use some Objective C syntax constructs even when
      compiling pure C, which confuses mainline gcc. Suppress this by
      setting OS_OBJECT_USE_OBJC=0. This avoids a compile error like this:

      configure: Don't override user's --cpu on MacOS and Solaris · bbea4050
      Peter Maydell authored
      
      
      Both MacOS and Solaris have special case handling for the CPU
      type, because the check_define probes will return i386 even if
      the hardware is 64 bit and x86_64 would be preferable. Move
      these checks earlier in the configure probing so that we can
      do them only if the user didn't specify a CPU with --cpu. This
      fixes a bug where the user's command line argument was being
      ignored.

      json-parser: don't replicate tokens at each level of recursion · 65c0f1e9
      Michael Roth authored
      
      
      Currently, when parsing a stream of tokens we make a copy of the token
      list at the beginning of each level of recursion so that we do not
      modify the original list in cases where we need to fall back to an
      earlier state.
      
      In the worst case, we will only read 1 or 2 tokens off the list before
      recursing again, which means an upper bound of roughly N^2 token allocations.
      
      For a "reasonably" sized QMP request (in this a QMP representation of
      cirrus_vga's device state, generated via QIDL, being passed in via
      qom-set), this caused my 16GB's of memory to be exhausted before any
      noticeable progress was made by the parser.
      
      This patch works around the issue by using single copy of the token list
      in the form of an indexable array so that we can save/restore state by
      manipulating indices.
      
      A subsequent commit adds a "large_dict" test case which exhibits the
      same behavior as above. With this patch applied the test case successfully
      completes in under a second.
      
      Tested with valgrind, make check, and QMP.
