vagrant vboxguestadditions prob-lame-os

$ vagrant up . . [bambam] GuestAdditions versions on your host (4.3.28) and guest (4.3.30) do not match. . . No package kernel-devel-2.6.32-573.7.1.el6.x86_64 available. . . Building the main Guest Additions module [FAILED] (Look at /var/log/vboxadd-install.log to find out what went wrong) . . . ==> bambam: Mounting shared folders... bambam: /vagrant => /Users/bambam/Vagrant/bambam/ Vagrant was unable to mount VirtualBox shared folders. This is usually because the filesystem "vboxsf" is not available. This filesystem is made available via the VirtualBox Guest Additions and kernel module. Please verify that these guest additions are properly installed in the guest. This is not a bug in Vagrant and is usually caused by a faulty Vagrant box. For context, the command attempted was: mount -t vboxsf -o uid=500,gid=500 vagrant /vagrant The error output from the command was:

...so lame...

Well once I tried this and it worked.

$ vagrant plugin install vagrant-vbguest Installing the 'vagrant-vbguest' plugin. This can take a few minutes... Installed the plugin 'vagrant-vbguest (0.13.0)'!

Not this time, so I had to log into the box and check the guest additions symlink was in the right place.

$ vagrant ssh [vagrant@bambam ~]$ sudo ln -s /opt/VBoxGuestAdditions-4.3.28/lib/VBoxGuestAdditions /usr/lib/VBoxGuestAdditions [vagrant@bambam ~]# ls -l /usr/lib/VBoxGuestAdditions lrwxrwxrwx 1 root root 53 Apr 9 17:09 /usr/lib/VBoxGuestAdditions -> /opt/VBoxGuestAdditions-4.3.28/lib/VBoxGuestAdditions

Worked once before, but unfortunately not this time :( Some guy on stack overflow recommended turning off the auto update by adding this to the Vagrantfile:

config.vbguest.auto_update = false

...Didn't work. I went over the original output about the failure,,,

No package kernel-devel-2.6.32-573.7.1.el6.x86_64 available.

I check the kernel

[vagrant@bambam ~]$ uname -r 2.6.32-642.6.1.el6.x86_64 [vagrant@bambam ~]$ ls -l /usr/src/kernels/ total 4 drwxr-xr-x. 22 root root 4096 Oct 23 08:24 2.6.32-642.6.1.el6.x86_64

Binary diff between libc from ScientificLinux and CentOS

In our IRC channel the question arose how we can see the difference between binaries build on different systems (SL and CentOS in this case).

Our initial test binary was created using this snippet:

yum install vala glib2-devel echo 'print("Hello");' > a.vala valac a.vala && objdump -D a

We came then up with this small script to automate the diff creation:

dump() { TMPFILE=$(mktemp) objdump -D $1 > $TMPFILE cat $TMPFILE | sed "s/^[[:space:]]\+[0-9a-f]\+//" rm $TMPFILE } cmp_dump() { dump $1 > dump_a dump $2 > dump_b diff -u dump_a dump_b rm dump_a dump_b } # Usage: cmp_dump first-binary second-binary $@

So to compare two binaries and return the diff between their obj dump output (without addresses) you run:

bash cmp_dump.sh libc-sl libc-centos

This lead us to this result for libc from CentOS and ScientificLinux:

--- dump_a 2013-09-11 12:39:30.799452944 +0200 +++ dump_b 2013-09-11 12:39:32.061467634 +0200 @@ -1,5 +1,5 @@ -libc-2.12.so-centos6: file format elf64-x86-64 +libc-2.12.so-sl6: file format elf64-x86-64 Disassembly of section .note.gnu.build-id: @@ -13,13 +13,18 @@ : 00 00 add %al,(%rax) : 47 rex.RXB : 4e 55 rex.WRX push %rbp -: 00 34 95 f7 bc a6 d9 add %dh,-0x26594309(,%rdx,4) -: 9e sahf -: 30 1d 7c 9f 95 9a xor %bl,-0x656a6084(%rip) # ffffffff9a95a209 <_end+0xffffffff9a5c7961> -: 87 0f xchg %ecx,(%rdi) -: 8e 77 c0 mov -0x40(%rdi),%? -: f0 lock -: b7 .byte 0xb7 +: 00 9a df 3d a2 9c add %bl,-0x635dc221(%rdx) +: 0c 20 or $0x20,%al +: 70 7f jo 308 <data.10540+0x2a8> +: ed in (%dx),%eax +: 6d insl (%dx),%es:(%rdi) +: 49 9a rex.WB (bad) +: 2b 20 sub (%rax),%esp +: 0e (bad) +: 67 addr32 +: 6b .byte 0x6b +: 68 .byte 0x68 +: b1 .byte 0xb1 Disassembly of section .note.ABI-tag: @@ -486756,6 +486761,5 @@ : 62 (bad) : 75 67 jne 79 <data.10540+0x19> : 00 00 add %al,(%rax) -: c7 (bad) -: fc cld -: 87 37 xchg %esi,(%rdi) +: da 38 fidivrl (%rax) +: 73 e0 jae fffffffffffffff8 <_end+0xffffffffffc6d750>

This ain't a big difference for a 2M+ file, is it?

So is this a valuable way to compare binaries?

At the end there is the question: Can this be used to compare if binaries from an RPM were really created from the sources of it's SRPM?
