aufs-util for aufs3.2 and later, but aufs is 3.2-20130708

2013-07-12 Thread Guan Xin

   Hello,
   Today I tried to make aufs-utils and got this:
   cc -I./libau-O-Wall-I/usr/src/linux-3.2.48/usr/include
   -I/usr/src/aufs/aufs3-standalone/usr/include -DMOUNT_CMD_PATH=\\ Â  ver.c
   Â  -o ver
   ./ver
   Wrong version!
   aufs-util for aufs3.2 and later, but aufs is 3.2-20130708.
   make: *** [ver_test] Error 255
   rm ver
   Did I misunderstand something? Is aufs version 3.2-20130708 later than
   aufs3.2 or is it rather aufs3.0?
   Thanks!
   Guan

Ouch!!
That is my bad.
It will be fixed in next Monday release.

Re: Aufs support for Linux User namespace

2013-07-12 Thread sfjro

Hello Bhushan,

Bhushan Jain:
 Linux kernel 3.8 has added support for user namespace which allows 
 unprivileged users to create different namespaces for sandboxing within the 
 user namespace. The filesystem developers need to explicitly allow mounting 
 their filesystem types within a user namespace. This explicit permission is 
 required because an overall unprivileged user of the system can be mapped to 
 a root user within a user namespace. Most of the Linux filesystems already 
 support user namespaces.

If you can, please provide me
- sample usage of user-namespace
- sample case where user-namespace and aufs is beneficial


 This use namespace support can be added by a small change in the file 
 fs/aufs/super.c to add
 flag FS_USERNS_MOUNT to aufs_fs_type (shown in bold below). Please let me 
 know if you would like me to send a patch including this change.

The change is apparently small, but the patch is better because it will
record your name in the git history.

Just out of curiosity, do you know any recent activity on Unionfs?
