* [PATCH] tmpfs: Enable atomic inode security labelingStephen Smalley2005-09-09
| | | | | | | | | | | | | | | | | | | | | This patch modifies tmpfs to call the inode_init_security LSM hook to set up the incore inode security state for new inodes before the inode becomes accessible via the dcache. As there is no underlying storage of security xattrs in this case, it is not necessary for the hook to return the (name, value, len) triple to the tmpfs code, so this patch also modifies the SELinux hook function to correctly handle the case where the (name, value, len) pointers are NULL. The hook call is needed in tmpfs in order to support proper security labeling of tmpfs inodes (e.g. for udev with tmpfs /dev in Fedora). With this change in place, we should then be able to remove the security_inode_post_create/mkdir/... hooks safely.

* [PATCH] security: enable atomic inode security labelingStephen Smalley2005-09-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The following patch set enables atomic security labeling of newly created inodes by altering the fs code to invoke a new LSM hook to obtain the security attribute to apply to a newly created inode and to set up the incore inode security state during the inode creation transaction. This parallels the existing processing for setting ACLs on newly created inodes. Otherwise, it is possible for new inodes to be accessed by another thread via the dcache prior to complete security setup (presently handled by the post_create/mkdir/... LSM hooks in the VFS) and a newly created inode may be left unlabeled on the disk in the event of a crash. SELinux presently works around the issue by ensuring that the incore inode security label is initialized to a special SID that is inaccessible to unprivileged processes (in accordance with policy), thereby preventing inappropriate access but potentially causing false denials on legitimate accesses. A simple test program demonstrates such false denials on SELinux, and the patch solves the problem. Similar such false denials have been encountered in real applications. This patch defines a new inode_init_security LSM hook to obtain the security attribute to apply to a newly created inode and to set up the incore inode security state for it, and adds a corresponding hook function implementation to SELinux.

* [PATCH] update filesystems for new delete_inode behaviorMark Fasheh2005-09-09
| | | | | | | | | | | | | | Update the file systems in fs/ implementing a delete_inode() callback to call truncate_inode_pages(). One implementation note: In developing this patch I put the calls to truncate_inode_pages() at the very top of those filesystems delete_inode() callbacks in order to retain the previous behavior. I'm guessing that some of those could probably be optimized.

* [PATCH] move truncate_inode_pages() into ->delete_inode()Mark Fasheh2005-09-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Allow file systems supporting ->delete_inode() to call truncate_inode_pages() on their own. OCFS2 wants this so it can query the cluster before making a final decision on whether to wipe an inode from disk or not. In some corner cases an inode marked on the local node via voting may not actually get orphaned. A good example is node death before the transaction moving the inode to the orphan dir commits to the journal. Without this patch, the truncate_inode_pages() call in generic_delete_inode() would discard valid data for such inodes. During earlier discussion in the 2.6.13 merge plan thread, Christoph Hellwig indicated that other file systems might also find this useful. IMHO, the best solution would be to just allow ->drop_inode() to do the cluster query but it seems that would require a substantial reworking of that section of the code. Assuming it is safe to call write_inode_now() in ocfs2_delete_inode() for those inodes which won't actually get wiped, this solution should get us by for now. Trivial testing of this patch (and a related OCFS2 update) has shown this to avoid the corruption I'm seeing.

| * Allow PCI config space syscalls to be used by 64-bit processes.Paul Mackerras2005-09-09
| | | | | | | | | | | | | | | | | | | | The pciconfig_iobase, pciconfig_read and pciconfig_write system calls were only implemented for 32-bit processes; for 64-bit processes they returned an ENOSYS error. This allows them to be used by 64-bit processes as well. The X server uses pciconfig_iobase at least, and this change is necessary to allow a 64-bit X server to work on my G5.

| * [PATCH] PPC64: large INITRD causes kernel not to bootMark Bellon2005-09-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In PPC64 there are number of problems in arch/ppc64/boot/main.c that prevent a kernel from making use of a large (greater than ~16MB) INITRD. This is 64 bit architecture and really large INITRD images should be possible. Simply put the existing code has a fixed reservation (claim) address and once the kernel plus initrd image are large enough to pass this address all sorts of bad things occur. The fix is the dynamically establish the first claim address above the loaded kernel plus initrd (plus some "padding" and rounding). If PROG_START is defined this will be used as the minimum safe address - currently known to be 0x01400000 for the firmwares tested so far.
