Hi I have long group names in my /etc/groups file. The longer the name the more crazy gridftp behaves. *up to 8 chars is: - ok *over 8 up to about 25 or so: - last 8 chars in name *long names (40+ chars) - segfault! ran110@file2-per:/cem/compgeo> ls -la total 16 drwxrwxrwx 8 root Computational_Geoscience 119 2008-05-07 10:02 . drwxr-xr-x 3 root root 20 2008-04-08 17:31 .. drwxrwx--- 29 ran110 CG_Admin_Access 4096 2008-04-30 17:08 CGAdmin drwxrwx--- 4 ran110 CEM-CGForcast 42 2008-04-30 16:47 CGForecast drwxrwx--- 51 ran110 Computational_Geoscience 4096 2008-05-05 08:23 Comp_geosci drwxrwx--- 22 ran110 Computational_Geoscience_Industry_Applications_Group 4096 2008-04-30 21:18 IndustryProjects drwxrwx--- 3 ran110 Computational_Geoscience 18 2008-04-30 20:34 Inversions drwxrwx--- 19 lec012 CEM-Model 4096 2008-05-04 22:19 ModellingProjects guess which group makes gridftp crash? Computational_Geoscience_Industry_Applications_Group I would be happy with anything BUT a segfault.
Thanks for reporting this. I see an obvious cause of this in the cases where the LIST or STAT commands are being used. Is that how you're hitting the problem?
yes every client we use issues: cwd and then list and the server crashes and the clients are left not having a clue! currently this looks like a buffer overflow and should probably be treated as one. Terry Rankine
Fixed and committed to cvs. An updated globus_gridftp_server_control package will be available at http://globus.org/toolkit/advisories.html Mike
