[PULL 01/19] linux-user, alpha: fix oldumount syscall

[Laurent Vivier]

When we try to bootstrap debian/lenny for alpha, it fails because
it cannot umount /.root directory:

  ...
  Setting up initscripts (2.86.ds1-61) ...
  umount: /.root: Function not implemented
  dpkg: error processing initscripts (--configure):
   subprocess post-installation script returned error exit status 1
  dpkg: sysvinit: dependency problems, but configuring anyway as you request:
   sysvinit depends on initscripts; however:
    Package initscripts is not configured yet.

This is because, when we switched from syscall_nr.h to syscall.tbl,
the syscall #321 has been renamed from umount to oldumount and
syscall.c has not been updated to manage the new name.

oldumount has been introduced in linux 2.1.116pre1 by:
  7d32756b2 ("Import 2.1.116pre1")
...
 * We now support a flag for forced unmount like the other 'big iron'
 * unixes. Our API is identical to OSF/1 to avoid making a mess of AMD
...

[PULL 05/19] linux-user/mmap.c: fix integer underflow in target_mremap

[Laurent Vivier]

From: Jonathan Marler <johnnymarler@gmail.com>

Fixes: https://bugs.launchpad.net/bugs/1876373

This code path in mmap occurs when a page size is decreased with mremap.  When a section of pages is shrunk, qemu calls mmap_reserve on the pages that were released.  However, it has the diff operation reversed, subtracting the larger old_size from the smaller new_size.  Instead, it should be subtracting the smaller new_size from the larger old_size.  You can also see in the previous line of the change that this mmap_reserve call only occurs when old_size > new_size.

[PULL 19/19] stubs: Restrict ui/win32-kbd-hook to system-mode

[Laurent Vivier]

From: Philippe Mathieu-Daudé <philmd@redhat.com>

In Makefile.objs, the ui/ directory is restricted to system-mode:

 43 ifeq ($(CONFIG_SOFTMMU),y)
 ...
 65 common-obj-y += ui/
 66 common-obj-m += ui/
 ...
 82 endif # CONFIG_SOFTMMU

Restrict the ui/ stub added in commit 2df9f5718df to only build
it for system-mode emulation.

Hi; this failed to compile on s390 and ppc when building hppa-linux-user:

/home/ubuntu/qemu/linux-user/syscall.c: In function ‘do_openat’:
/home/ubuntu/qemu/linux-user/syscall.c:7484:42: error: ‘is_proc’
undeclared (first use in this function); did you mean ‘
is_error’?
         { "/proc/cpuinfo", open_cpuinfo, is_proc },
                                          ^~~~~~~
                                          is_error
/home/ubuntu/qemu/linux-user/syscall.c:7484:42: note: each undeclared
identifier is reported only once for each function
 it appears in
/home/ubuntu/qemu/rules.mak:69: recipe for target 'linux-user/syscall.o' failed

Looks like this is because the #if condition guarding the
is_proc() definition doesn't line up with the uses (missing
a check on TARGET_HPPA).

thanks

You're right.

I was thinking this kind of problem would be detected by the travis-ci
builds, but in fact ppc64 and s390 builds don't build other architecture
linux-user targets.

I update my PR.

Thanks,
Laurent

That's an unfortunate gap in the CI -- we should ideally cover
the whole tree with at least one big-endian platform.

Indeed.  Hopefully we can do this with our pending gitlab setup.

For travis, IIRC we only build this restricted set because we had problems with
timeouts on those machines.

Right. But we could add one more tests with
--target-list-exclude=${MAIN_SOFTMMU_TARGETS} --enable-user in Travis
... I'll have a look...
