Description Ryan Ding 2016-08-23 16:40:24 UTC

Description of problem:

in function server_readlink_cbk, if readlink got a file system error (like ENOENT, etc.), rsp.path will leave to be NULL. and this will lead a xdr error in xdr_gfs3_readlink_rsp. original errno is lost.

    protocol/server: readlink rsp xdr will fail while readlink got an error
    
    set gfs3_readlink_rsp.path with an empty string while error happen, to
    make xdr_gfs3_readlink_rsp happy. otherwise the original errno will be
    lost, and return an rpc internal errno instead.
