Konstantin Khlebnikov b862e561ba Smack: handle zero-length security labels without panic ... Zero-length security labels are invalid but kernel should handle them. This patch fixes kernel panic after setting zero-length security labels: # attr -S -s "SMACK64" -V "" file And after writing zero-length string into smackfs files syslog and onlycp: # python -c 'import os; os.write(1, "")' > /smack/syslog The problem is caused by brain-damaged logic in function smk_parse_smack() which takes pointer to buffer and its length but if length below or equal zero it thinks that the buffer is zero-terminated. Unfortunately callers of this function are widely used and proper fix requires serious refactoring. Signed-off-by: Konstantin Khlebnikov <k.khlebnikov@samsung.com>		2014-08-08 14:51:07 -07:00
