-D variables not honored

[matt]

Within /etc/default/autofs I have:
OPTIONS="-DOSREL=2.6"

running ps I get:
root 3474 1 0 09:16 ? 00:00:00 /usr/sbin/automount -DOSREL=2.6

My map looks like this:
bin FILER:/vol/usrlocal/&/$ARCH/${OSNAME}$OSREL

But automount won't use the OSREL:
May 23 09:41:29 xco-ubuntu1404 automount[3474]: >> mount.nfs: access denied by server while mounting FILER:/vol/usrlocal/bin/x86_64/Linux3.13.0-24-generic

This setup works fine under RHEL4-7 and according to the documentation should work fine under ubuntu.

Status changed to 'Confirmed' because the bug affects multiple users.

Neither environment variables nor ones specified on command line seemed to work.
Building 5.0.9 seems to have fixed the issue for us.

The way I used to test it:

echo "/test /etc/auto.test" >/etc/auto.master
echo 'test1 ${MYPATH}' >/etc/auto.test
echo 'OPTIONS="-DMYPATH=:/tmp"' >/etc/defaults/autofs
service autofs restart
automount -l debug /test

in the logs you'll see:

Jul 16 00:13:00 xxxx automount[7338]: attempting to mount entry /test/test1
Jul 16 00:13:00 xxxx automount[7338]: dev_ioctl_send_fail: token = 7
Jul 16 00:13:00 xxxx automount[7338]: failed to mount /test/test1

Sorry, there was a typo in the following line:
echo 'OPTIONS="-DMYPATH=:/tmp"' >>/etc/defaults/autofs

I experienced this problem when updating a client from Ubuntu 12.04 to 14.04. Our file server is running SunOS 5.11 but the symptom is the same. For us, It's not a source code problem but the way modules/parse_sun.c is compiled.

Here's the gcc line for parse_sun from a default debuild of the Ubuntu 14.04 autofs package source:

gcc -Wl,-Bsymbolic-functions -Wl,-z,relro -s -lpthread -s -lpthread -shared -g -O2 -fstack-protector --param=ssp-buffer-size=4 -Wformat -Werror=format-security -D_FORTIFY_SOURCE=2 -D_REENTRANT -D_FILE_OFFSET_BITS=64 -D_REENTRANT -D_FILE_OFFSET_BITS=64 -DSSS_LIB_DIR=\"/usr/lib/x86_64-linux-gnu/sssd/modules\" -I../include -I../lib -fPIC -D_GNU_SOURCE -DAUTOFS_LIB_DIR=\"/usr/lib/x86_64-linux-gnu/autofs\" -DAUTOFS_MAP_DIR=\"/etc\" -o parse_sun.so parse_sun.c ../lib/autofs.a -lnsl

If I remove the '-Wl,-Bsymbolic-functions' chunk from that gcc line and run it manually, then copy the resulting parse_sun.so to /usr/lib/x86_64-linux-gnu/autofs/, it works. Then /usr/sbin/automount starts following the -D flags again.

I was able to create a working package bumping the version in the changelog (no need to alter source) then running:

DEB_LDFLAGS_SET='-Wl,-z,relro' debuild

That reduces the default dpkg-buildflags from

-Wl,-Bsymbolic-functions -Wl,-z,relro

to

-Wl,-z,relro

to remove the problematic 'symbolic-functions' linker option that was causing the problem for me. You could try it under a Linux NFS server. I suspect it'll fix the problem in whatever library is causing the same issue for automounting Linux servers.

Landon's suggestion appears to be a fix for us too (thanks!). I did alter the source package so I don't have to remember that should the package have to be rebuilt one day. I set DEB_LDFLAGS_SET on the main call to debhelper. I've included a patch to be precise.

That does not appear to be a good solution by Lintian's standards, so I will not mark this as a solution for this bug. This is just a quick fix for us.

[Ubuntu Foundations Team Bug Bot (crichton)]

The attachment "patch implementing Landon's suggestion inside of debian/rules" seems to be a patch. If it isn't, please remove the "patch" flag from the attachment, remove the "patch" tag, and if you are a member of the ~ubuntu-reviewers, unsubscribe the team.

[Brian Murray (brian-murray)]

For what I can tell this is still an issue with the version of autofs in Vivid which will become Ubuntu 15.04 and also in the Debian version of the package. Subsequently, it would be helpful if you were to submit this bug to Debian.

Thanks!

It seems https://bugs.launchpad.net/ubuntu/+source/autofs/+bug/1470687 will resolve this issue?
