use gnulib, and begin to pass its "make syntax-check" tests

by Jim Meyering

Here's a patch series to make libguestfs use gnulib via a git submodule. The first thing I did was to look at the failures from "make syntax-check" and fix the config.h-related ones below. The others are now temporarily disabled via a variable in cfg.mk. I fixed the config-h problems and moved those change sets to precede the test-adding one, so that bisection still works, even if you use the new "syntax-check" rule as your metric. As I fix others, I'll remove the rule name from the disabled-tests list. >From 3d13b4e3062a3b06d9ed3acadb4cb55fb41a05c8 Mon Sep 17 00:00:00 2001 From: Jim Meyering <meyering(a)redhat.com> Date: Mon, 3 Aug 2009 06:58:16 -0400 Subject: [PATCH 1/4] build: add -I option to get config.h. * ocaml/Makefile.am (AM_CPPFLAGS): Define.

[REPOST] Use grub entries to find Linux kernels

by Matthew Booth

This is a repost of the patch I sent on Friday. I know it was already ACK'd, but I've changed a fair bit in addition to adding the requested POD. Specifically: I discovered that augeas's grub lens wasn't returning cmdline the way I expected. This is fixed. The kernel package, if known, is output as a property of the kernel. The XML output of virt-inspector is updated with all the new output.

[PATCH] Use grub entries to find Linux kernels

by Matthew Booth

This change adds grub parsing to Lib.pm. It adds the following structure to $os: {boot} ->{configs} ->[0] ->{title} = "Fedora (2.6.29.6-213.fc11.i686.PAE)" ->{kernel} = \kernel ->{cmdline} = "ro root=/dev/mapper/vg_mbooth-lv_root rhgb" ->{initrd} = \initrd ->{default} = 0 The kernel and initrd entries are just references to their top level entries under kernels and initrd_modules respectively. It also changes the way Linux kernels and initrd are discovered. Instead of searching /lib/modules and /boot for files with matching names, kernels and initrds are scanned as they are discovered in grub.conf. --- perl/lib/Sys/Guestfs/Lib.pm | 278 +++++++++++++++++++++++++++++-------------- 1 files changed, 189 insertions(+), 89 deletions(-) diff --git a/perl/lib/Sys/Guestfs/Lib.pm b/perl/lib/Sys/Guestfs/Lib.pm index bbc583f..20e29ff 100644 --- a/perl/lib/Sys/Guestfs/Lib.pm +++ b/perl/lib/Sys/Guestfs/Lib.pm @@ -1343,7 +1343,6 @@ sub inspect_in_detail _check_for_kernels ($g, $os); if ($os->{os} eq "linux") { _find_modprobe_aliases ($g, $os); - _check_for_initrd ($g, $os); } } @@ -1392,48 +1391,170 @@ sub _check_for_applications sub _check_for_kernels { - local $_; - my $g = shift; - my $os = shift; + my ($g, $os) = @_; - my @kernels; + if ($os->{os} eq "linux") { + # Iterate over entries in grub.conf, populating $os->{boot} + # For every kernel we find, inspect it and add to $os->{kernels} + + my @boot_configs; + + # We want + # $os->{boot} + # ->{configs} + # ->[0] + # ->{title} = "Fedora (2.6.29.6-213.fc11.i686.PAE)" + # ->{kernel} = \kernel + # ->{cmdline} = "ro root=/dev/mapper/vg_mbooth-lv_root rhgb" + # ->{initrd} = \initrd + # ->{default} = \config + # Initialise augeas + $g->aug_init("/", 16); + + my @configs = (); + # Get all configurations from grub + foreach my $bootable + ($g->aug_match("/files/etc/grub.conf/title")) + { + my %config = (); + $config{title} = $g->aug_get($bootable); + + my $grub_kernel; + eval { + $grub_kernel = $g->aug_get("$bootable/kernel"); + }; + if($@) { + warn __x("Grub entry {title} has no kernel", + title => $config{title}); + } - my $osn = $os->{os}; - if ($osn eq "linux") { - # Installed kernels will have a corresponding /lib/modules/<version> - # directory, which is the easiest way to find out what kernels - # are installed, and what modules are available. - foreach ($g->ls ("/lib/modules")) { - if ($g->is_dir ("/lib/modules/$_")) { - my %kernel; - $kernel{version} = $_; - - # List modules. - my @modules; - my $any_module; - my $prefix = "/lib/modules/$_"; - foreach ($g->find ($prefix)) { - if (m,/([^/]+)\.ko$, || m,([^/]+)\.o$,) { - $any_module = "$prefix$_" unless defined $any_module; - push @modules, $1; - } - } + # Check we've got a kernel entry + if(defined($grub_kernel)) { + # Parse a kernel path and optional kernel command line + if($grub_kernel =~ /^\s*(\S+)(?:\s+(.*))?$/) { + my $kernel_path = $1; + $config{cmdline} = $2 if defined($2); + + my $kernel = _inspect_linux_kernel($g, $os, "/boot$1"); + + # Check the kernel was recognised + if(defined($kernel)) { + $config{kernel} = $kernel; + + # Look for an initrd entry + my $initrd; + eval { + $initrd = $g->aug_get("$bootable/initrd"); + }; + + unless($@) { + $config{initrd} = + _inspect_initrd($g, $os, "/boot$initrd", + $kernel->{version}); + } else { + warn __x("Grub entry {title} does not specify an ". + "initrd", title => $config{title}); + } + } + } + else { + warn __x("Unexpected grub kernel line: {grub_kernel}", + grub_kernel => $grub_kernel); + next; + } + } - $kernel{modules} = \@modules; + push(@configs, \%config); + } - # Determine kernel architecture by looking at the arch - # of any kernel module. - $kernel{arch} = file_architecture ($g, $any_module); - push @kernels, \%kernel; - } - } + # Create the top level boot entry + my %boot; + $boot{configs} = \@configs; - } elsif ($osn eq "windows") { + # Add the default configuration + eval { + $boot{default} = $g->aug_get("/files/etc/grub.conf/default"); + }; + if($@) { + warn __"No grub default specified"; + } + + $os->{boot} = \%boot; + } + + elsif ($os->{os} eq "windows") { # XXX } +} + +sub _inspect_linux_kernel +{ + my ($g, $os, $path) = @_; + + my %kernel = (); + + $kernel{path} = $path; + + # Try to get the kernel version by running file against it + my $version; + my $filedesc = $g->file($path); + if($filedesc =~ /^$path: Linux kernel .*\bversion\s+(\S+)\b/) { + $version = $1; + } + + # Sometimes file can't work out the kernel version, for example because it's + # a Xen PV kernel.
