2009-09-08jffs2/jfs/xfs: switch over to 'check_acl' rather than 'permission()'Linus Torvalds
This avoids an indirect call in the VFS for each path component lookup. Well, at least as long as you own the directory in question, and the ACL check is unnecessary.

2008-07-26[PATCH] sanitize ->permission() prototypeAl Viro
* kill nameidata * argument; map the 3 bits in ->flags anybody cares about to new MAY_... ones and pass with the mask. * kill redundant gfs2_iop_permission() * sanitize ecryptfs_permission() * fix remaining places where ->permission() instances might barf on new MAY_... found in mask.

2007-10-20[JFFS2] Tidy up fix for ACL/permissions problem.KaiGai Kohei
[In commit 9ed437c50d89eabae763dd422579f73fdebf288d we fixed a problem with standard permissions on newly-created inodes, when POSIX ACLs are enabled. This cleans it up...] The attached patch separate jffs2_init_acl() into two parts. The one is jffs2_init_acl_pre() called from jffs2_new_inode(). It compute ACL oriented inode->i_mode bits, and allocate in-memory ACL objects associated with the new inode just before when inode meta infomation is written to the medium. The other is jffs2_init_acl_post() called from jffs2_symlink(), jffs2_mkdir(), jffs2_mknod() and jffs2_do_create(). It actually writes in-memory ACL objects into the medium next to the success of writing meta-information. In the current implementation, we have to write a same inode meta infomation twice when inode->i_mode is updated by the default ACL. However, we can avoid the behavior by putting an updated i_mode before it is written at first, as jffs2_init_acl_pre() doing.

2007-08-22[JFFS2] Fix ACL vs. mode handling.David Woodhouse
When POSIX ACL support was enabled, we weren't writing correct legacy modes to the medium on inode creation, or when the ACL was set. This meant that the permissions would be incorrect after the file system was remounted. Signed-off-by: David Woodhouse <dwmw2@infradead.org>
2007-04-25[JFFS2] Tidy up licensing/copyright boilerplate.David Woodhouse
In particular, remove the bit in the LICENCE file about contacting Red Hat for alternative arrangements. Their errant IS department broke that arrangement a long time ago -- the policy of collecting copyright assignments from contributors came to an end when the plug was pulled on the servers hosting the project, without notice or reason. We do still dual-license it for use with eCos, with the GPL+exception licence approved by the FSF as being GPL-compatible. It's just that nobody has the right to license it differently.

2006-07-02[JFFS2][XATTR] Fix memory leak in POSIX-ACL supportKaiGai Kohei
jffs2_clear_acl() which releases acl caches allocated by kmalloc() was defined but it was never called. Thus, we faced to the risk of memory leaking. This patch plugs jffs2_clear_acl() into jffs2_do_clear_inode(). It ensures to release acl cache when inode is cleared.

2006-05-13[JFFS2][XATTR] XATTR support on JFFS2 (version. 5)KaiGai Kohei
This attached patches provide xattr support including POSIX-ACL and SELinux support on JFFS2 (version.5). There are some significant differences from previous version posted at last December. The biggest change is addition of EBS(Erase Block Summary) support. Currently, both kernel and usermode utility (sumtool) can recognize xattr nodes which have JFFS2_NODETYPE_XATTR/_XREF nodetype. In addition, some bugs are fixed. - A potential race condition was fixed. - Unexpected fail when updating a xattr by same name/value pair was fixed. - A bug when removing xattr name/value pair was fixed. The fundamental structures (such as using two new nodetypes and exclusion mechanism by rwsem) are unchanged. But most of implementation were reviewed and updated if necessary. Espacially, we had to change several internal implementations related to load_xattr_datum() to avoid a potential race condition.
