[Buildroot] [PATCH v3 1/1] package/network-manager: add patches to build with kernel headers 3.2

[Petr Vorel]

From: Petr Vorel <petr.vorel@gmail.com>

+ lower kernel headers dependency

According to upstream [1], there is no known minimal kernel-version, nor
minimal required feature-set.

Experimentally tested, that 1.0.2 is works with 3.2 kernel headers, even
some features will be missing [2].

Changes v3:
 - Lower kernel headers dependency to 3.2
 - Preserved original author of
   0002-systemd-dhcp-fix-build-with-Linux-3.2.0-headers.patch
 - Added Signed-off-by inside both patches.
Changes v2: rewrited patch 0002-systemd-dhcp-fix-build-with-Linux-3.2.0-headers.patch

 "works" as in run-time tested?

 Basically it _may_ also work with lower kernel headers but hasn't been tested,
right? Ideally, it would be nice to do a (build-)test with 2.6.34-ish. Or else,
you could add a comment saying that it could work with lower headers. The
minimal headers version was anyway only introduced to fix an autobuild failure.

 Arnout

I've done some brief tests, I'll do more testing probably this week. Ok, I should have
wait and post the patch after more testing. Anyway I need to get it work even on lower
kernel than 3.2 (obviously some features will be missing, but NetworkManager cannot
crash). Upstream is willing to accept simple patches which fixes behaviour on older
kernels.

>  Upstream status?
Not sure if I understand your question. The patch was taken from upstream.

Why 2.6.34-ish? The minimum kernel version in toolchain/toolchain-common.in after
BR2_TOOLCHAIN_HEADERS_AT_LEAST_3_0 is 2.6, which is unspecified.

Do you mean to keep BR2_TOOLCHAIN_HEADERS_AT_LEAST_3_7 and mention in "help" lower
versions?

 No, it's a good idea to already post before that. But then it's also a good
idea to mention that you haven't done runtime testing :-)

 Well, it's not strictly necessary to do that, just nice to have.

 Sorry, my bad, the commit sha is indeed at the beginning of the patch.

 Indeed, we consider everything pre-3.0 as ancient. 2.6.34 is just a random
pre-3.0 version that I have seen in use recently.

 No, I mean: change it to 3.2 and mention in a comment that it might work on
lower versions. Like:

	# Tested with 3.2, but may even work with earlier versions
	depends on BR2_TOOLCHAIN_HEADERS_AT_LEAST_3_2

 Arnout

Applied after adding a comment in Config.in saying that it may work with
older kernel headers than 3.2, as suggested by Arnout.

Of course, when upstream makes a new release with those patches
integrated, it would be good if you could send a new Buildroot patch to
use this new upstream release.

Thanks a lot!
