--------------------------------------
Summary: Dubious SSH_FXP_REALPATH handling
Key: SSHD-294
URL: https://issues.apache.org/jira/browse/SSHD-294
Project: MINA SSHD
Issue Type: Bug
Affects Versions: 0.10.0
Reporter: Kohsuke Kawaguchi
SSH_FXP_REALPATH is used to canonicalizing path on the server side, so clients
often send path names that do not exist. The procol
(http://tools.ietf.org/html/draft-ietf-secsh-filexfer-02) clearly states that
it should respond with dummy attribute values.
SftpSubsystem class, OTOH, attempts to return actual file attributes, which
could fail on non-existent paths (or if the path exists but is at the location
the user doesn't have access to.)
Handler for SSH_FXP_REALPATH shouldn't attempt to get attributes, or if you do,
it must recover from errors in SshFile and report dummy values instead.
