  Subject: [PATCH] util: fix to get configuration macros in util/mmap-alloc.c

  Message-Id: <20200305154142.63070-1-jingqi.liu@intel.com>

Before moving the osdep.h include to the top of the file, we had
to address warnings triggered when <linux/mman.h> was included
after <sys/mman.h> (done in patch 1/2).

  Use -isystem for linux-headers dir

[PATCH v2 1/2] Use -isystem for linux-headers dir

[Eduardo Habkost]

glibc and Linux-provided headers are known to generate macro
redefinition warnings when used together.  For example:
<linux/mman.h> and <sys/mman.h> duplicate some macro definitions.

We normally never see those warnings because GCC suppresses
warnings generated by system headers.  We carry our own copy of
Linux header files, though, and this makes those warnings not be
suppressed when glibc headers are included before Linux headers
(e.g. if <sys/mman.h> is included before <linux/mman.h>).

Use -isystem instead of -I for linux-headers.  This makes the
compiler treat our linux-headers directory the same way it treats
system-provided Linux headers, and suppress warnings generated by
them.

I wondered whether this changed the search order for the headers
(ie whether it meant we now picked up our copy of the header
and not the system header in some cases), but both -I and -isystem
directories are searched before the standard system headers,
so the only effect is the warning suppression.

[PATCH v2 2/2] mmap-alloc: Include osdep.h before checking CONFIG_LINUX

[Eduardo Habkost]

The CONFIG_LINUX check at the top of mmap-alloc.c never worked
because it was done before including osdep.h.

This means MAP_SYNC and MAP_SHARED_VALIDATE would always be set
to 0 at the beginning of the file.  Luckily, this didn't break
when using recent glibc versions (2.28+), because those macros
were redefined by glibc headers.

Move the CONFIG_LINUX check after the main include lines, so the
CONFIG_LINUX check works and we actually include <linux/mman.h>.
This will make MAP_SYNC and MAP_SHARED_VALIDATE available even if
the host has an older glibc version.

This breaks the build on mips, because mips doesn't have MAP_SYNC
defined at linux/mman.h:

Wait a second, MAP_SHARED_VALIDATE is from
linux-headers/linux/mman.h - it's available on all architectures.

Oops. But that in fact means it's currently building on mips but not
working correctly there! MAP_SHARED_VALIDATE 0x0 is especially
problematic. I'm unsure what's the right thing to do is,
I guess as a first step we can go back and device MAP_SYNC to 0,

Yes, but both MAP_SYNC and MAP_SHARED_VALIDATE aren't available
if the host is not Linux.

Defining MAP_SYNC to 0 on MIPS would restore the existing
behavior, so it seems like a reasonable step to fix the build
failure.  But not even printing a warning when the host doesn't
have MAP_SYNC (the existing behavior on MIPS and non-Linux) seems
wrong.

The usual approach is that if you don't have the Linux-specific
feature available you quietly fall back to whatever the sensible
behaviour is for when the feature isn't present. We definitely
don't want to be printing warnings on non-Linux systems that
are effectively just saying "you're not running Linux". Same goes
for "host happens not to be running a bleeding-edge Linux kernel
and this feature isn't available yet".

I don't think using pmem=on without MAP_SYNC is expected to be a
supported use case, is it?  If a use case is not supported, the
sensible behavior is to tell the user it is not supported.

Futher when eventually an arch does gain the feature, not failing
when it's not available would mean users have no way to detect
what's actually going on.

Yeah, that's fair. But the code at the moment does a fallback
to "proceed without SHARED_VALIDATE | SYNC", so I assumed it
was supposed to work.
