jfs: Replace zero-length array with flexible-array member

2020-03-09T20:18:51Z

The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.

jfs: Switch to generic xattr handlers

2016-05-13T02:29:18Z

This is mostly the same as on other filesystems except for attribute names with an "os2." prefix: for those, the prefix is not stored on disk, and on-attribute names without a prefix have "os2." added. As on several other filesystems, the underlying function for setting/removing xattrs (__jfs_setxattr) removes attributes when the value is NULL, so the set xattr handlers will work as expected.

jfs: use generic posix ACL infrastructure

Copy the scheme I introduced to btrfs many years ago to only use the xattr handler for ACLs, but pass plain attrs straight through. Signed-off-by: Christoph Hellwig Reviewed-by: Dave Kleikamp Signed-off-by: Al Viro

fs/vfs/security: pass last path component to LSM on inode creation

2011-02-01T16:12:29Z

SELinux would like to implement a new labeling behavior of newly created inodes. We currently label new inodes based on the parent and the creating process. This new behavior would also take into account the name of the new object when deciding the new label. This is not the (supposed) full path, just the last component of the path. This is very useful because creating /etc/shadow is different than creating /etc/passwd but the kernel hooks are unable to differentiate these operations. We currently require that userspace realize it is doing some difficult operation like that and than userspace jumps through SELinux hoops to get things set up correctly. This patch does not implement new behavior, that is obviously contained in a seperate SELinux patch, but it does pass the needed name down to the correct LSM hook. If no such name exists it is fine to pass NULL. Signed-off-by: Eric Paris
