smb: client: ensure to try all targets when finding nested links

2023-08-20T21:05:50+00:00

With current implementation, when a nested DFS link is found during mount(2), the client follows the referral and then try to connect to all of its targets. If all targets failed, the client bails out rather than retrying remaining targets from previous referral. Fix this by stacking all referrals and targets so the client can retry remaining targets from previous referrals in case all targets of current referral have failed. Thanks to samba, this can be easily tested like below * Run the following under dfs folder in samba server $ ln -s "msdfs:srv\\bad-share" link1 $ ln -s "msdfs:srv\\dfs\\link1,srv\\good-share" link0 * Before patch $ mount.cifs //srv/dfs/link0 /mnt -o ... mount error(2): No such file or directory Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)... * After patch $ mount.cifs //srv/dfs/link0 /mnt -o ... # ls /mnt bar fileshare1 sub Signed-off-by: Paulo Alcantara (SUSE) Signed-off-by: Steve French
