Re: glibc 2.14-4 eats my data (Re: F15 ext3, eCryptfs + samba = data corruption (Re: F15 "Error mounting eCryptfs: [-5] Input/output error" on different disks))

Hi,

When I did a glibc downgrade to 2.13.90-9 eCryptfs mount problem no
longer appears, also there is no data corruption problem. Glibc
changes somehow breaks eCryptfs and probably also samba.

Hi,

Do anyone noticed any problems with mounting eCryptfs recently on F15?
It seems to me unlikely that I have an I/O errors on few disks.
Especially if only eCryptfs reports them.

I've got two dirs

/home/s1 - ext3
/home/s2 - ext3 + eCryptfs

If I copy a file from my laptop to /home/s1 it has md5 sum
c7da3acc8e85f64661b49b9788771bf6
when I copy this file from shell to /home/s2 it has the same md5 sum
c7da3acc8e85f64661b49b9788771bf6

If I copy the same file from my laptop to /home/s2 I get a strange error
in Total commander "please remove the write protection" - TC's progress bar
doesn't show any progress - after copying file has correct size, but
it's totally
broken - md5 sum
f26767c3aed2f6e639ddb9ad6601daaf

Does anyone have any idea what could be wrong? I guess that data corruption
problem is related to this strange "Error mounting eCryptfs: [-5]
Input/output error"
message.

Check dmesg,

nothing here

your the logs

Some samba problem

File size is correct

selinux perhaps?

disabled



What is perhaps important is that the problem appears for files > +/- 1GB.

Hmmm... wonder if this is somehow related to glibc changing memcpy that caused problem in flash and squashfs?
