 |
|
Hello,
recently one of our gentoo desktop clients has started to show problems when trying to automount some nfs shares. Standard logs didn't show anything interesting, so I ran the automounter with:
| Code: | | automount -d -v -f /etc/auto.master |
And I get these messages:
| Code: |

Autofs configuration is delivered networkwide via nis, so /etc/auto.master reads just
| Code: | | /home /etc/auto.home |
and
| Code: |
# cat /etc/auto.home
+auto.home
# ypcat auto.home
-rw,rsize=8192,wsize=8192,intr,tcp nfs_server:/lhome0/myuser

I am running automount 5.1.1-r1 on gentoo sources 4.4.6
From the automount output, I see that it gets the correct mount options but, for some reason, it fails to mount the directory.
Of course, I am able to directly mount that directory.
nfs_server is running ubuntu 12.04, but it is not under my control and other gentoo clients in the network can automount that directory just fine.
I believe this started to happen after the last sync&update, but I'm not sure if that is the cause
Some other info:

Kernel config is here
Any ideas? |

Ok, I have an update:
| Code: | # ldd /usr/sbin/automount
linux-vdso.so.1 (0x00007ffc21fb6000)
libpthread.so.0 => /lib64/libpthread.so.0 (0x00007fa0e8249000)
libdl.so.2 => /lib64/libdl.so.2 (0x00007fa0e8045000)
libc.so.6 => /lib64/libc.so.6 (0x00007fa0e7ca9000)
/lib64/ld-linux-x86-64.so.2 (0x00007fa0e8465000) |
This seems all normal, but if I remove --as-needed from LDFLAGS
| Code: | # ldd /usr/sbin/automount
linux-vdso.so.1 (0x00007ffe349d1000)
libpthread.so.0 => /lib64/libpthread.so.0 (0x00007f14d272a000)
libtirpc.so.1 => /lib64/libtirpc.so.1 (0x00007f14d2503000)
libnsl.so.1 => /lib64/libnsl.so.1 (0x00007f14d22eb000)
libdl.so.2 => /lib64/libdl.so.2 (0x00007f14d20e7000)
libc.so.6 => /lib64/libc.so.6 (0x00007f14d1d4b000)
/lib64/ld-linux-x86-64.so.2 (0x00007f14d2946000) |
Now two more libraries are linked and automount works as expected. The odd thing is that on other gentoo boxes, which have --as-needed enabled, automount still works fine. |

libtirpc should depend on the libtirpc useflag, but once set, the build system should link and use them, --as-needed no has need to remove them, as its task is to remove link lib that are in real not use.
if you have in your examples the libtirpc useflag set, then it's a bug that should be report. Because --as-needed or not, if one was build with it set and the other not, that's expected result then. |

Hello, I made a few more experiments and this is what I see:
On all of my gentoo boxes, autofs was built with libtirpc use flag enabled but it doesn't work on only one box
It will work if I remove the --as-needed flag
functions from libtirpc are called in modules/rpc_subs.c file but if I remove it from the Makefile and I do not link against libtirpc, autofs emerges but does not work
if I disable libtirpc use flag, autofs works even with --as-needed
