[gentoo-user] uname -a question

[Ernie Schroder]

Where does uname find kernel version? For my last 2 new kernels, uname -a 
returns some off the wall kernel version. It seems to be picking up extra 
info from God know where.

$ uname -a
Linux MRK 2.6.15-gentoo-r12.6.14-r-4_new #1 Fri Jan 27 12:38:49 EST 2006 i686 
AMD Athlon(tm) XP 2400+ AuthenticAMD GNU/Linux

running kernel lines from grub.conf:

title  Gentoo-2.6.15
root   (hd0,0)
kernel /bzImage-2.6.15-r1 root=/dev/hda5

cat /proc/version
Linux version 2.6.15-gentoo-r12.6.14-r-4_new (root@MRK) (gcc version 3.4.4 
(Gentoo 3.4.4-r1, ssp-3.4.4-1.0, pie-8.7.8)) #1 Fri Jan 27 12:38:49 EST 2006

/lib/modules for the new kernels is affected too:

$ locate r12.6.14-r-4_new
/lib/modules/2.6.15-gentoo-r12.6.14-r-4_new
<snip>

Everything is working just fine, but this is annoying me to no end.

It comes from the version embedded in the kernel, returned via the
uname system call (man 2 uname).

carcharias rjf # strace -v -e uname uname
uname({sysname="Linux", nodename="carcharias",
release="2.6.15-suspend2-r3", version="#3 PREEMPT Sat Jan 21 10:00:05
MST 2006", machine="i686"}) = 0
uname({sysname="Linux", nodename="carcharias",
release="2.6.15-suspend2-r3", version="#3 PREEMPT Sat Jan 21 10:00:05
MST 2006", machine="i686"}) = 0

There are various ways these versions can be set, including
EXTRAVERSION and LOCALVERSION.

What are using to build these kernels?

 using the typical change symlink copy over .config, make oldconfig make && 
make modules_install    cp arch etc.
Obviously, I made a typo last upgrade but I can't figure out how to fix it 
now.

What does " grep VERSION /usr/src/linux/.config" return?

$ grep VERSION /usr/src/linux/.config
CONFIG_LOCALVERSION="2.6.14-r-4_new"

Hmm that seems to be it. It would appear that I have to rebuild the kernel 
with appropriate version descriptor. I used my old config and added the 
2.6.14-r4-new string when I built that kernel. I guess I'll just live with it 
until I build another one. Thanks Neil.

You need to set it to "", but it's not critical for now.

So true! I am annoyed by this but as far as I can see, the only way to get rid 
of the string is to rebuild my kernel. I guess I'll wait for the next version 
bump.

I thought that this was in the top 4 lines of the kernel Makefile.
It's embedded in the kernel after the kernel is compiled.
Example is from my servers below for the 2.4 kernel.
The extraversion line is set to whatever I want...it just appends
that to the end of kernel name...so if you want to have two 2.4.31
kernels you just change the extra version to something different
to differenciate between the kernels.

Standard location is going to be /usr/src/linux/Makefile

*VERSION = 2
PATCHLEVEL = 4
SUBLEVEL = 31
EXTRAVERSION = -gentoo-r1*

*KERNELRELEASE=$(VERSION).$(PATCHLEVEL).$(SUBLEVEL)$(EXTRAVERSION)*

This is still true with the 2.6 kernel, except that there is now also
a LOCALVERSION that comes from the .config file.
