2008-06-06introduce memory_read_from_buffer()Akinobu Mita
This patch introduces memory_read_from_buffer(). The only difference between memory_read_from_buffer() and simple_read_from_buffer() is which address space the function copies to. simple_read_from_buffer copies to user space memory. memory_read_from_buffer copies to normal memory.

2008-06-06eCryptfs: remove unnecessary page decrypt callMichael Halcrow
The page decrypt calls in ecryptfs_write() are both pointless and buggy. Pointless because ecryptfs_get_locked_page() has already brought the page up to date, and buggy because prior mmap writes will just be blown away by the decrypt call. This patch also removes the declaration of a now-nonexistent function ecryptfs_write_zeros(). Thanks to Eric Sandeen and David Kleikamp for helping to track this down. Eric said: fsx w/ mmap dies quickly ( < 100 ops) without this, and survives nicely (to millions of ops+) with it in place.

2008-05-31capabilities: remain source compatible with 32-bit raw legacy capability ↵Andrew G. Morgan
support. Source code out there hard-codes a notion of what the _LINUX_CAPABILITY_VERSION #define means in terms of the semantics of the raw capability system calls capget() and capset(). Its unfortunate, but true. Since the confusing header file has been in a released kernel, there is software that is erroneously using 64-bit capabilities with the semantics of 32-bit compatibilities. These recently compiled programs may suffer corruption of their memory when sys_getcap() overwrites more memory than they are coded to expect, and the raising of added capabilities when using sys_capset(). As such, this patch does a number of things to clean up the situation for all. It 1. forces the _LINUX_CAPABILITY_VERSION define to always retain its legacy value. 2. adopts a new #define strategy for the kernel's internal implementation of the preferred magic. 3. deprecates v2 capability magic in favor of a new (v3) magic number. The functionality of v3 is entirely equivalent to v2, the only difference being that the v2 magic causes the kernel to log a "deprecated" warning so the admin can find applications that may be using v2 inappropriately. [User space code continues to be encouraged to use the libcap API which protects the application from details like this. libcap-2.10 is the first to support v3 capabilities.] Fixes issue reported in https://bugzilla.redhat.com/show_bug.cgi?id=447518.

Based on Roland's patch. This approach was suggested by Austin Clements from the very beginning, and then by Linus. As Austin pointed out, the execing task can be killed by SI_TIMER signal because exec flushes the signal handlers, but doesn't discard the pending signals generated by posix timers.

2008-05-26ext4: enable barriers by defaultEric Sandeen
I can't think of any valid reason for ext4 to not use barriers when they are available; I believe this is necessary for filesystem integrity in the face of a volatile write cache on storage. An administrator who trusts that the cache is sufficiently battery- backed (and power supplies are sufficiently redundant, etc...) can always turn it back off again. SuSE has carried such a patch for ext3 for quite some time now. Also document the mount option while we're at it.

2008-05-25disable most mode changes on non-unix/non-cifsacl mountsJeff Layton
CIFS currently allows you to change the mode of an inode on a share that doesn't have unix extensions enabled, and isn't using cifsacl. The inode in this case *only* has its mode changed in memory on the client. This is problematic since it can change any time the inode is purged from the cache. This patch makes cifs_setattr silently ignore most mode changes when unix extensions and cifsacl support are not enabled, and when the share is not mounted with the "dynperm" option. The exceptions are: When a mode change would remove all write access to an inode we turn on the ATTR_READONLY bit on the server and remove all write bits from the inode's mode in memory. When a mode change would add a write bit to an inode that previously had them all turned off, it turns off the ATTR_READONLY bit on the server, and resets the mode back to what it would normally be (generally, the file_mode or dir_mode of the share).

Fuse allocates a separate bdi for each filesystem, and registers them in sysfs with "MAJOR:MINOR" of sb->s_dev (st_dev). This works fine for anon devices normally used by fuse, but can conflict with an already registered BDI for "fuseblk" filesystems, where sb->s_dev represents a real block device. In particularl this happens if a non-partitioned device is being mounted. Fix by registering with a different name for "fuseblk" filesystems. Thanks to Ioan Ionita for the bug report.

Have CIFS silently ignore ownership changes that can't be persistently stored on the server unless the "setuids" option is explicitly specified. We could return an error here (-EOPNOTSUPP or something), but this is how most disk-based windows filesystems on behave on Linux (e.g. VFAT, NTFS, etc).

2008-05-23when creating new inodes, use file_mode/dir_mode exclusively on mount ↵Jeff Layton
without unix extensions When CIFS creates a new inode on a mount without unix extensions, it temporarily assigns the mode that was passed to it in the create/mkdir call. Eventually, when the inode is revalidated, it changes to have the file_mode or dir_mode for the mount. This is confusing to users who expect that the mode shouldn't change this way. It's also problematic since only the mode is treated this way, not the uid or gid. Suppose you have a CIFS mount that's mounted with: uid=0,gid=0,file_mode=0666,dir_mode=0777 ...if an unprivileged user comes along and does this on the mount: mkdir -m 0700 foo touch foo/bar ...there is a period of time where the touch will fail, since the dir will initially be owned by root and have mode 0700. If the user waits long enough, then "foo" will be revalidated and will get the correct dir_mode permissions. This patch changes cifs_mkdir and cifs_create to not overwrite the mode found by the initial cifs_get_inode_info call after the inode is created on the server. Legacy behavior can be reenabled with the new "dynperm" mount option. Signed-off-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: Steve French <sfrench@us.ibm.com>
2008-05-23on non-posix shares, clear write bits in mode when ATTR_READONLY is setJeff Layton

Directories and other inode types, however, can also have ATTR_READONLY set, but the mode gives no indication of this. This patch makes this apply to other inode types besides regular files. It also cleans up how modes are set in cifs_get_inode_info for both the "normal" and "dynperm" cases. Signed-off-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: Steve French <sfrench@us.ibm.com>

2008-05-23[XFS] Fix fsync() b0rkage.David Chinner
xfs_fsync() fails to wait for data I/O completion before checking if the inode is dirty or clean to decide whether to log the inode or not. This misses inode size updates when the data flushed by the fsync() is extending the file. Hence, like fdatasync(), we need to wait for I/o completion first, then check the inode for cleanliness. Doing so makes the behaviour of xfs_fsync() identical for fsync and fdatasync and we *always* use synchronous semantics if the inode is dirty. Therefore also kill the differences and remove the unused flags from the xfs_fsync function and callers.
