jfs: fix generic posix ACL regression

2014-02-08T16:50:58+00:00

I missed a couple errors in reviewing the patches converting jfs
to use the generic posix ACL function. Setting ACL's currently
fails with -EOPNOTSUPP.

jfs: use generic posix ACL infrastructure

2014-01-26T04:58:22+00:00

Copy the scheme I introduced to btrfs many years ago to only use the
xattr handler for ACLs, but pass plain attrs straight through.

jfs: fix xattr value size overflow in __jfs_setxattr

2014-01-02T17:36:56+00:00

There is a potential overflow if the specified EA value size is
greater than USHRT_MAX because the size of value is limited by
the on-disk format (i.e, __le16), this issue could be reflected
via the tests below:
 # touch /jfs/testfile
 # setfattr -n user.comment -v `perl -e 'print "A"x65536'` /jfs/testfile
   setfattr: /jfs/testfile: Invalid argument

Syslog:
 ... jfs_xsetattr: xattr_size = 21, new_size = 65557

This patch add pre-checkups of EA value size against USHRT_MAX to
avoid this problem, and return -E2BIG which is consistent with the
VFS setxattr interface.  Moreover, fix the debug code to print the
correct function name.

With this fix:
 setfattr: /jfs/testfile: Argument list too long

jfs: Update jfs_error

2013-06-05T19:47:19+00:00

Use a more current logging style.

Add __printf format and argument verification.

Remove embedded function names from formats.
Add %pf, __builtin_return_address(0) to jfs_error.
Add newlines to formats for kernel style consistency.
(One format already had an erroneous newline)
Coalesce formats and align arguments.

Object size reduced ~1KiB.

userns: Pass a userns parameter into posix_acl_to_xattr and posix_acl_from_xattr

2012-09-18T08:01:35+00:00

 - Pass the user namespace the uid and gid values in the xattr are stored
   in into posix_acl_from_xattr.

 - Pass the user namespace kuid and kgid values should be converted into
   when storing uid and gid values in an xattr in posix_acl_to_xattr.

- Modify all callers of posix_acl_from_xattr and posix_acl_to_xattr to
  pass in &init_user_ns.

In the short term this change is not strictly needed but it makes the
code clearer.  In the longer term this change is necessary to be able to
mount filesystems outside of the initial user namespace that natively
store posix acls in the linux xattr format.
