      target/xtensa: linux-user: fix sysv IPC structures · a3da8be5
      由 Max Filippov 提交于 
      - make target_ipc_perm fields match kernel definitions for xtensa;
- add target_semid64_ds with proper order of times and reserved fields
  for little/big endian specific for xtensa;
- add missing reserved fields after time fields to the target_shmid_ds;
- fix types of shm_cpid, shm_lpid and shm_nattch fields of
  target_shmid_ds to match kernel definitions for xtensa.

These changes fix guest ipcs output and fix glibc testsuite tests
sysvipc/test-sysvsem and sysvipc/test-sysvshm.

      linux-user: fix mq_getsetattr implementation · a23ea409
      由 Max Filippov 提交于 
      mq_getsetattr implementation does not set errno correctly in case of
error. Also in the presence of both 2nd and 3rd arguments it calls both
mq_getattr and mq_setattr, whereas only the latter call would suffice.

Don't call mq_getattr in the presence of the 2nd argument. Don't copy
output back to user in case of error. Use get_errno to set errno value.

This fixes test rt/tst-mqueue2 from the glibc testsuite.

      linux-user: call cpu_copy under clone_lock · 73a988d9
      由 Max Filippov 提交于 
      cpu_copy adds newly created CPU object to container/machine/unattached,
but does it w/o proper locking. As a result when multiple threads create
threads rapidly QEMU may abort with the following message:

  GLib-CRITICAL **: g_hash_table_iter_next: assertion
  'ri->version == ri->hash_table->version' failed

  ERROR:qemu/qom/object.c:1663:object_get_canonical_path_component:
  code should not be reached

E.g. this issue is observed when running glibc test nptl/tst-eintr1.
Move cpu_copy invocation under clone_lock to fix that.

      target/xtensa: fix flush_window_regs · 20ef6670
      由 Max Filippov 提交于 
      flush_window_regs uses wrong stack frame to save overflow registers in
call8 and call12 frames, which results in wrong register values in
callers of a function that received a signal.
Reimplement flush_window_regs closely following window overflow
sequence.
