Description Sheena Artrip 2018-02-13 21:16:10 UTC

Description of problem:

Methods rpcsvc_program_register_rpcbind6/rpcsvc_program_unregister_rpcbind6 do not get exported with the symbol table when compiling --with-ipv6-default.

Version-Release number of selected component (if applicable): 

4.0, mainline

How reproducible:

Always

Steps to Reproduce:
1. Compile gluster with --with-ipv6-default. 
2. Check exported symbols of libgfrpc.so, see no rpcbind6

1. Compile gluster with --with-ipv6-default, --with-gnfs 
2. Run gluster
3. See nfs daemon crash with unable to lookup symbol rpcsvc_program_register_rpcbind6

Actual results:

libgfrpc does not have rpcbind6. gnfsd crashes with symbol import error.

nm -D /usr/lib64/libgfrpc.so -l | grep rpcbind6; echo $? => 1

nfs.log:

[2018-02-13 21:08:27.351949] W [MSGID: 101095] [xlator.c:433:xlator_dynload] 0-xlator: /usr/lib64/glusterfs/3.8dev/xlator/nfs/server.so: undefined symbol: rpcsvc_program_register_rpcbind6


Expected results:

libgfrpc has rpcbind6. gnfsd runs and listens ipv6 address.

nm -D /usr/lib64/libgfrpc.so -l | grep rpcbind6; echo $? => 0

Additional info:

Bug introduced when file rpc-lib/src/libgfrpc.sym was introduced. fix simple, incoming.

COMMIT: https://review.gluster.org/19563 committed in master by  with a commit message- rpc: Adds rpcbind6 programs to libgfrpc symbols

Building with --with-default-ipv6 causes shared
components of gluster calling the rpcbind6 functions
to fail. Adding the symbols in the list is all that is
necessary. Building without ipv6 keeps the same behavior.

No test cases as this is a build-specific fix.
