      linux-user: fix TARGET_NR_select · 5457dc9e
      由 Laurent Vivier 提交于 
      TARGET_NR_select can have three different implementations:

  1- to always return -ENOSYS

     microblaze, ppc, ppc64

     -> TARGET_WANT_NI_OLD_SELECT

  2- to take parameters from a structure pointed by arg1
    (kernel sys_old_select)

     i386, arm, m68k

     -> TARGET_WANT_OLD_SYS_SELECT

  3- to take parameters from arg[1-5]
     (kernel sys_select)

     x86_64, alpha, s390x,
     cris, sparc, sparc64

Some (new) architectures don't define NR_select,

  4- but only NR__newselect with sys_select:

      mips, mips64, sh

  5- don't define NR__newselect, and use pselect6 syscall:

      aarch64, openrisc, tilegx, unicore32

      linux-user: Fix incorrect offset of tuc_stack in ARM do_sigframe_return_v2 · 45eafb4d
      由 Timothy E Baldwin 提交于 
      struct target_ucontext_v2 is not at the begining of the signal frame,
therefore do_sigaltstack was being passed bogus arguments.

As the offset depends on the type of signal frame fixed by passing in the
beginning of the context from do_sigreturn_v2 and do_rt_sigreturn_v2.

      linux-user: Sanity check clone flags · 5ea2fc84
      由 Peter Maydell 提交于 
      We currently make no checks on the flags passed to the clone syscall,
which means we will not fail clone attempts which ask for features
that we can't implement. Add sanity checking of the flags to clone
(which we were already doing in the "this is a fork" path, but not
for the "this is a new thread" path), tidy up the checking in
the fork path to match it, and check that the fork case isn't trying
to specify a custom termination signal.

This is helpful in causing some LTP test cases to fail cleanly
rather than behaving bizarrely when we let the clone succeed
but didn't provide the semantics requested by the flags.

      linux-user: Remove unnecessary nptl_flags variable from do_fork() · 7cfbd386
      由 Peter Maydell 提交于 
      The 'nptl_flags' variable in do_fork() is set to a copy of
'flags', and then the CLONE_NPTL_FLAGS are cleared out of 'flags'.
However the only effect of this is that the later check on
"if (flags & CLONE_PARENT_SETTID)" is never true. Since we
will already have done the setting of parent_tidptr in clone_func()
in the child thread, we don't need to do it again.

Delete the dead if() and the clearing of CLONE_NPTL_FLAGS from
'flags', and then use 'flags' where we were previously using
'nptl_flags', so we can delete the unnecessary variable.
