Summary: ecrypts does not preserve correctly timestamps for "cp
-p"
Product: File System
Version: 2.5
Kernel Version: 2.6.39-rc3
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: ecryptfs
AssignedTo: fs_ecryptfs at kernel-bugs.osdl.org
ReportedBy: rockorequin at hotmail.com
Regression: Yes
With the 2.6.39-rc3 kernel, assuming I have a file tt in a non-ecryptfs file
system and I do the following:
mkdir test
sudo mount -t ecryptfs test test -o
ecryptfs_cipher=aes,ecryptfs_key_bytes=16,ecryptfs_passthrough=n,ecryptfs_enable_filename_crypto=y
cd test
cp -p ../tt .
then the recently-copied file 'tt' in ecrypts has its modified timestamp set to
when it was copied rather than that of original file.
This also happens when copying within the ecryptfs system.
Strangely, it doesn't always happen immediately - the timestamp may be correct
for a minute or so - so maybe there is some caching involved.
