2007-02-20[PATCH] affs: implement ->drop_inodeChristoph Hellwig
affs wants to truncate the inode when the last user goes away, currently it does that through a potentially racy i_count check in ->put_inode. But we already have a method that's called just after the we dropped the last reference, ->drop_inode. This patch implements affs_drop_inode to take advantage of this.

2007-02-20[PATCH] autofs4: check for directory re-create in lookupIan Kent
This problem was identified and fixed some time ago by Jeff Moyer but it fell through the cracks somehow. It is possible that a user space application could remove and re-create a directory during a request. To avoid returning a failure from lookup incorrectly when our current dentry is unhashed we need to check if another positive, hashed dentry matching this one exists and if so return it instead of a fail.

2007-02-20[PATCH] autofs4: fix another race between mount and expireIan Kent
Jeff Moyer has identified a race between mount and expire. What happens is that during an expire the situation can arise that a directory is removed and another lookup is done before the expire issues a completion status to the kernel module. In this case, since the the lookup gets a new dentry, it doesn't know that there is an expire in progress and when it posts its mount request, matches the existing expire request and waits for its completion. ENOENT is then returned to user space from lookup (as the dentry passed in is now unhashed) without having performed the mount request. The solution used here is to keep track of dentrys in this unhashed state and reuse them, if possible, in order to preserve the flags. Additionally, this infrastructure will provide the framework for the reintroduction of caching of mount fails removed earlier in development.

2007-02-20[PATCH] fs: fix nobh data leakNick Piggin
nobh_prepare_write leaks data similarly to how simple_prepare_write did. Fix by not marking the page uptodate until nobh_commit_write time. Again, this could break weird use-cases, but none appear to exist in the tree. We can safely remove the set_page_dirty, because as the comment says, nobh_commit_write does set_page_dirty. If a filesystem wants to allocate backing store for a page dirtied via mmap, page_mkwrite is the suggested approach.

2007-02-20[PATCH] fs: fix libfs data leakNick Piggin
simple_prepare_write leaks uninitialised kernel data. This happens because the it leaves an uninitialised "hole" over the part of the page that the write is expected to go to. This is fine, but it then marks the page uptodate, which means a concurrent read can come in and copy the uninitialised memory into userspace before it written to. Fix it by simply marking it uptodate in simple_commit_write instead, after the hole has been filled in. This could theoretically break an fs that uses simple_prepare_write and not simple_commit_write, and that relies on the incorrect simple_prepare_write behaviour. Luckily, none of those exists in the tree.

2007-02-189p: implement optional loose read cacheEric Van Hensbergen
While cacheing is generally frowned upon in the 9p world, it has its place -- particularly in situations where the remote file system is exclusive and/or read-only. The vacfs views of venti content addressable store are a real-world instance of such a situation. To facilitate higher performance for these workloads (and eventually use the fscache patches), we have enabled a "loose" cache mode which does not attempt to maintain any form of consistency on the page-cache or dcache. This results in over two orders of magnitude performance improvement for cacheable block reads in the Bonnie benchmark. The more aggressive use of the dcache also seems to improve metadata operational performance. Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>

We're inserting deny's between some ACEs in order to enforce posix draft acl semantics which prevent permissions from accumulating across entries in an acl. That's fine, but we're doing that by inserting a deny after *every* allow, which is overkill. We shouldn't be adding them in places where they actually make no difference. Also replaced some helper functions for creating acl entries; I prefer just assigning directly to the struct fields--it takes a few more lines, but the field names provide some documentation that I think makes the result easier understand.

2007-02-16[PATCH] knfsd: nfsd4: relax checking of ACL inheritance bitsJ. Bruce Fields
The rfc allows us to be more permissive about the ACL inheritance bits we accept: "If the server supports a single "inherit ACE" flag that applies to both files and directories, the server may reject the request (i.e., requiring the client to set both the file and directory inheritance flags). The server may also accept the request and silently turn on the ACE4_DIRECTORY_INHERIT_ACE flag." Let's take the latter option--the ACL is a complex attribute that could be rejected for a wide variety of reasons, and the protocol gives us little ability to explain the reason for the rejection, so erroring out is a user-unfriendly last resort.

2007-02-14[PATCH] sysctl: hide the sysctl proc inodes from selinuxEric W. Biederman
Since the security checks are applied on each read and write of a sysctl file, just like they are applied when calling sys_sysctl, they are redundant on the standard VFS constructs. Since it is difficult to compute the security labels on the standard VFS constructs we just mark the sysctl inodes in proc private so selinux won't even bother with them. Signed-off-by: Eric W.

2007-02-14[PATCH] sysctl: remove the proc_dir_entry member for the sysctl tablesEric W. Biederman
It isn't needed anymore, all of the users are gone, and all of the ctl_table initializers have been converted to use explicit names of the fields they are initializing.

2007-02-14[PATCH] sysctl: reimplement the sysctl proc supportEric W. Biederman
With this change the sysctl inodes can be cached and nothing needs to be done when removing a sysctl table. For a cost of 2K code we will save about 4K of static tables (when we remove de from ctl_table) and 70K in proc_dir_entries that we will not allocate, or about half that on a 32bit arch. The speed feels about the same, even though we can now cache the sysctl dentries :( We get the core advantage that we don't need to have a 1 to 1 mapping between ctl table entries and proc files. Making it possible to have /proc/sys vary depending on the namespace you are in. The currently merged namespaces don't have an issue here but the network namespace under /proc/sys/net needs to have different directories depending on which network adapters are visible. By simply being a cache different directories being visible depending on who you are is trivial to implement.
