[PATCH v1 1/1] srcu-cbmc: Use /usr/bin/awk instead of /bin/awk

[PATCH v1 1/1] srcu-cbmc: Use /usr/bin/awk instead of /bin/awk

[priyalee.kushwaha]

From: Priyalee Kushwaha <priyalee.kushwaha@intel.com>

Most OS distribution have awk in /usr/bin not in /bin
Without this patch, kernel-devsrc fails to build as
runtime dependency for srcu-cbmc script /bin/awk is
not found.

Re: [PATCH v1 1/1] srcu-cbmc: Use /usr/bin/awk instead of /bin/awk

[Lance Roy]

This is fine with me. I didn't notice that /bin/awk was just a symlink on the
distro I was using when I wrote the script.

Thanks,
Lance

For anyone that has it in /bin/awk, does it have a compatibility symlink
from /usr/bin/awk (or vice versa), or not?  If not, then this would
break the build for those folks.

We could just drop the shebang and the executable bit, and run "awk -f
modify_srcu.awk" from whatever script invokes this.

RE: [PATCH v1 1/1] srcu-cbmc: Use /usr/bin/awk instead of /bin/awk

[Kushwaha, Priyalee]

Tested 9 distros centos, Debian, Fedora, Gentoo, Opensuse, slackware, Ubuntu, poky showed awk at /usr/bin/awk. 

Here is another similar patch which has been approved https://patchwork.kernel.org/patch/9650581/

centos-7:
lrwxrwxrwx 1 root root 4 Mar 15 19:58 /bin/awk -> gawk lrwxrwxrwx 1 root root 4 Mar 15 19:58 /usr/bin/awk -> gawk

Debian-8:
ls: cannot access /bin/awk: No such file or directory lrwxrwxrwx 1 root root 21 Mar 20 23:26 /usr/bin/awk -> /etc/alternatives/awk

Fedora:
lrwxrwxrwx. 1 root root 4 Sep 12  2016 /bin/awk -> gawk lrwxrwxrwx. 1 root root 4 Sep 12  2016 /usr/bin/awk -> gawk

Gentoo:
lrwxrwxrwx 1 root root 15 Jan  1 13:57 /bin/awk -> ../usr/bin/gawk lrwxrwxrwx 1 root root  4 Jan  1 13:57 /usr/bin/awk -> gawk

Opensuse:

Slackware:

Ubuntu:
ls: cannot access '/bin/awk': No such file or directory lrwxrwxrwx 1 root root 21 Dec  6  2015 /usr/bin/awk -> /etc/alternatives/awk

Poky:
ls: /bin/awk: No such file or directory
lrwxrwxrwx    1 root     root            19 Apr 20 22:59 /usr/bin/awk

This seems fairly conclusive.  Based on this, switching over to
/usr/bin/awk seems fine.

Hi Paul,

If this change looks good, please Ack it so I can take it through kselftest
tree. If you would like to take this through rcu, that is fine as well.

Hello, Shuah,

I have queued it with Lance's ack and Josh's review.

Just for full disclosure, my recent SRCU work has broken srcu-cbmc,
and a bit more breakage is on its way.  :-(

That said, I would welcome patches to fix it -- mostly adjustments in
pathnames, structure names, and which fields get removed.  Adjusting it
to work correctly with Classic SRCU would probably be a bit easier than
adapting it to either Tree SRCU or Tiny SRCU.

							Thanx, Paul
