Without these patches, to build an upgraded kernel on a Debian machine,
one has to use commands I keep on forgetting:

	make oldconfig
	make
	fakeroot -u make deb-pkg

With these patches applied, as long as fakeroot is installed, a single
command will do:

	make oldconfig deb-pkg

If fakeroot is not installed, there should be no change in behavior.
I have been using this to build the last few kernels, finding it very
convenient.

I look forward to your thoughts, even if they are just "I have no time
to look at this now".  I would like to get an idea of whether people
think these patches are a good idea, so I can fix them if they're
broken and chase them out of my local tree.

Allow "make foo-pkg" to acquire root or fake root privileges before
running commands that need it.  This is especially important for
tar-pkg, since otherwise if a user forgets to run make as root, the
installed kernel will have that user as owner and can easily be
overwritten by a broken program running as that user later.

The new ROOTCMD variable, if defined, is used as a command to run
other commands with possibly fake elevated privileges.  If it is not
defined, the behavior is as before, and hopefully make is running as
root already.

In other words, as a shortcut, instead of running

$ make oldconfig &&
> make &&
> fakeroot -u make rpm-pkg

now one can use a single command:

$ make oldconfig rpm-pkg ROOTCMD="fakeroot -u"

Unless already running as root, use fakeroot to ensure the files
in the generated binary packages are owned by root.  Without this
change, you have to set ROOTCMD or become root yourself to run
"make foo-pkg".

With this patch applied, you can run "make oldconfig rpm-pkg" as
an ordinary user to build a binary package for an updated kernel
tree and it should just work.

fakeroot is a bit too zealous by default in pretending files are
owned by root.  Unless directed otherwise, its wrapped stat() and
lstat() set st_uid and st_gid to 0 for all files.  This slows
down the Linux build with CONFIG_LOCALVERSION_AUTO a lot, since
git notices that the owners have changed and has to reread the
entire kernel tree to learn that the content has not changed.
Since "make modules_install" and "scripts/package/foo" run within
the same fakeroot session, we are free to avoid this by telling
fakeroot to use the actual owner and group for preexisting files,
by passing it the -u option.

I have not yet started to look at -next material where
this obviously belongs.
I skimmed the path last time you sent it (and have it queued
in my inbox) and my first reaction was:

    Is ROOTCMD an established way to specify this?

I asked google and not too many hits.
So I think we should come up with something more in the
line of the other stuff we have.

That could be the longer:

   KBUILD_PKG_ROOTCMD

Which with the KBUILD_ prefix could be a globel environment
variable for some.

The rationale for the _PKG is that this is restricted to
the *pkg targets (at least for now).

Agreed with this change. It is also more in line with how setting a root 
command is usually done in Debian. A grep of man pages on my system shows 
the following uses:
DEBUILD_ROOTCMD, BDPEP_ROOTCMD, UUPDATE_ROOTCMD, BUILDD_ROOTCMD, 
PBUILDERROOTCMD.

I have not tested it, but the patches look good otherwise, so with Sam's 
suggested change:

I also agree that this should land in -next as feature patch.
btw thanks for kicking that item of my TODO :)

Thanks, all.  Here’s an updated version, tested with a new build last
night.  This is indeed intended for -next.

Allow "make foo-pkg" to acquire root or fake root privileges before
running commands that need them.  This is especially important for
tar-pkg, since if buildtar is run as an unprivileged user, the
installed kernel will have that user as owner and can easily be
overwritten by a broken program running as that user later.

The new KBUILD_PKG_ROOTCMD variable, if defined, is used as a command
to run other commands with possibly fake elevated privileges.  Its use
is restricted to *pkg targets, hence the name.  If it is not defined,
the behavior is as before, and hopefully make is running as root
already.

In other words, as a shortcut, instead of running

	make oldconfig &&
	make &&
	fakeroot -u make rpm-pkg

now one can use a single command:

	make oldconfig rpm-pkg KBUILD_PKG_ROOTCMD="fakeroot -u"

Why is this needed for the rpm targets? The generates spec file doesn't
require root privileges and correctly sets root as the owner of the
packaged files.

GNU tar has --owner and --group options to override the owner and group
of the files in the archive, something like

opts=
if tar --owner=root --group=root --help >/dev/null 2>&1; then
    opts="--owner=root --group=root"
fi
tar cf - . $opts ...

would make tar-pkg do the right thing automatically without specifying
fakeroot. I don't know about deb-pkg, if it needs fakeroot, let's add
the variable, but it's not needed for *rpm-pkg and after a simple change
to buildtar it would not be needed for tar-pkg.

It was my ignorance of how rpm works.

Sounds appealing.  Probably it is safe to assume GNU tar is available
for running tar-pkg.  I’ll look into this, though I wouldn’t mind if a
patch appears before I finish.

Yes, deb-pkg needs it.

If this variable is to only be used for some targets, this help text
starts to look out of place.  Maybe make deb-pkg should error out with
a suggestion to set it if `id -u` is not 0, instead.

Thanks for the thoughtful review.  Updated patch coming soon.

I would still fallback to plain tar, you never know what exotic
system users build on and GNU tar is not mentioned in
Documentation/Changes. But you're right, this would be another patch.

Hi,

As Michal noticed, the tar*-pkg and *rpm-pkg targets can work fine
without being able to write files owned by root.  Only deb-pkg needs
to learn to acquire faked root privileges.  Here is an updated series
reflecting this.

This version no longer documents the KBUILD_PKG_ROOTCMD variable in
"make help" output.  If make already has root privileges or fakeroot
is installed, then the target will just work without any need for the
user to worry about this.  If not, instead of waiting from an error
from chmod, it seemed better to give an error right away with advice
to set KBUILD_PKG_ROOTCMD appropriately.

Since the scope of the variable’s applicability somewhat, I have not
carried over any acks.  But I am hoping you will still like the
patches. :)

From: Michal Marek <mmarek@suse.cz>

Use the --owner= and --group= options to make sure the entries in
the built tar file are owned by root.  Without this change, a
careless sysadmin using the tar-pkg target can easily end up
installing a kernel that is writable by the unprivileged user
account used to build the kernel.

Test that these options are understood before using them so that
non-GNU versions of tar can still be used if the operator is
appropriately cautious.

Let the deb-pkg target acquire (fake) root privileges before
running commands that need them.  Without such privileges,
deb-pkg errors out because chown fails.

The new KBUILD_PKG_ROOTCMD variable, if defined, is used as a
command to run other commands with possibly fake elevated
privileges.  Since this is not needed for the tar-pkg and rpm-pkg
targets, it is only used by deb-pkg.  If it is not defined, the
behavior is as before, and the user will have to rerun make as
root.

In other words, as a shortcut, instead of running 'make oldconfig &&
make && fakeroot -u make deb-pkg', one can use the single command
'make oldconfig deb-pkg KBUILD_PKG_ROOTCMD="fakeroot -u"'.

This patch does not use the variable in the rpm-pkg or tar-pkg targets
any more, since they already cope fine as non-root.

Running "make deb-pkg" requires setting KBUILD_PKG_ROOTCMD or
becoming root oneself or it errors out.  Unless already running
as root or KBUILD_PKG_ROOTCMD is already set, use fakeroot as a
good default.

With this patch applied, you can run "make oldconfig rpm-pkg" as
an ordinary user to build a binary package for an updated kernel
tree and it should just work.

fakeroot is too zealous by default in treating files as owned by
root.  Its wrapped stat() sets st_uid and st_gid to 0 for all
files, which causes Git to go on a wild goose chase if
CONFIG_LOCALVERSION_AUTO is set, checking if any file's content
has changed along with its stat information.  Avoid this by
telling fakeroot to use the actual owner and group for
preexisting files, by passing it the -u option.

The appropriate value for KBUILD_PKG_ROOTCMD is determined in the
rules for deb-pkg instead of the outer Makefile to avoid having to
fork for 'which' and 'id' for unrelated targets.

Before this change, the command for the deb-pkg target was not
abbreviated, so that normal output included something like "bash
/tmp/buildd/scripts/package/builddeb".  It is a shame to get rid of
this kind of transparency, but when I tried lying by setting
quiet_cmd_builddeb to that string, it was confusing to see 'make'
claiming to run that command through bash and not through fakeroot.
So I punted by abbreviating to BUILDDEB.  The curious can always use
"V=1".

Unless already running as root, use fakeroot to ensure the files in
the generated binary packages are owned by root.  Without this change,
you have to set KBUILD_PKG_ROOTCMD or become root yourself to run
"make foo-pkg".

With this patch applied, you can run "make oldconfig rpm-pkg" as an
ordinary user to build a binary package for an updated kernel tree and
it should just work.

fakeroot is a bit too zealous by default in pretending files are owned
by root.  Unless directed otherwise, its wrapped stat() and lstat()
set st_uid and st_gid to 0 for all files.  This slows down the Linux
build with CONFIG_LOCALVERSION_AUTO a lot, since git notices that the
owners have changed and has to reread the entire kernel tree to learn
that the content has not changed.  Since "make modules_install" and
"scripts/package/foo" run within the same fakeroot session, we are
free to avoid this by telling fakeroot to use the actual owner and
group for preexisting files, by passing it the -u option.
