2007-10-26[NET]: Marking struct pernet_operations __net_initdata was inappropriateEric W. Biederman1-1/+1
It is not safe to to place struct pernet_operations in a special section. We need struct pernet_operations to last until we call unregister_pernet_subsys. Which doesn't happen until module unload. So marking struct pernet_operations is a disaster for modules in two ways. - We discard it before we call the exit method it points to. - Because I keep struct pernet_operations on a linked list discarding it for compiled in code removes elements in the middle of a linked list and does horrible things for linked insert. So this looks safe assuming __exit_refok is not discarded for modules. Signed-off-by: Eric W. Biederman <ebiederm@xmission.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2007-10-23NFS: Fix for bug in handling of errors for O_DIRECT writesNeil Brown1-3/+3
Commit eda3cef8dd2b83875affe82595db9d0c278879b2 ("NFS: Fix error handling in nfs_direct_write_result()") ensured that if a WRITE returns an error, then data->res.verf->committed is not tested (as it is not initialised). Then commit 60fa3f769f7651a60125a0f44e3ffe3246d7cf39 ("NFS: Fix two bugs in the O_DIRECT write code") inadvertently reverted this while fixing other problems. So move the test so that we never examine ->committed in an error case, and fix a speeling error while we are there.

2007-10-22exportfs: add new methodsChristoph Hellwig2-6/+218
Add the guts for the new filesystem API to exportfs. There's now a fh_to_dentry method that returns a dentry for the object looked for given a filehandle fragment, and a fh_to_parent operation that returns the dentry for the encoded parent directory in case the file handle contains it. There are default implementations for these methods that only take a callback for an nfs-enhanced iget variant and implement the rest of the semantics.

2007-10-22exportfs: add fid typeChristoph Hellwig2-54/+49
This patchset is a medium scale rewrite of the export operations interface. The goal is to make the interface less complex, and easier to understand from the filesystem side, aswell as preparing generic support for exporting of 64bit inode numbers. This touches all nfs exporting filesystems, and I've done testing on all of the filesystems I have here locally (xfs, ext2, ext3, reiserfs, jfs) This patch: Add a structured fid type so that we don't have to pass an array of u32 values around everywhere. It's a union of possible layouts. As a start there's only the u32 array and the traditional 32bit inode format, but there will be more in one of my next patchset when I start to document the various filehandle formats we have in lowlevel filesystems better. Also add an enum that gives the various filehandle types human- readable names. Note: Some people might think the struct containing an anonymous union is ugly, but I didn't want to pass around a raw union type.

Well, it's not especially important that target->d_iname get the contents of dentry->d_iname, but it's important that it get initialized with *something*, otherwise we're just exposing some random piece of memory to anyone who reads the link at /proc/<pid>/fd/<fd> for the deleted file, when it's still held open by someone.

jffs2_write_end() is sometimes passing back a "written" length greater than the length we passed into it, leading to a BUG at mm/filemap.c:1749 when used with unionfs.

2007-10-21[PATCH] audit: watching subtreesAl Viro1-1/+1
New kind of audit rule predicates: "object is visible in given subtree". The part that can be sanely implemented, that is. Limitations: * if you have hardlink from outside of tree, you'd better watch it too (or just watch the object itself, obviously) * if you mount something under a watched tree, tell audit that new chunk should be added to watched subtrees * if you umount something in a watched tree and it's still mounted elsewhere, you will get matches on events happening there. New command tells audit to recalculate the trees, trimming such sources of false positives. Note that it's _not_ about path - if something mounted in several places (multiple mount, bindings, different namespaces, etc.), the match does _not_ depend on which one we are using for access.

2007-10-20[JFFS2] Tidy up fix for ACL/permissions problem.KaiGai Kohei6-87/+94
[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.
