* mm: Remove slab destructors from kmem_cache_create().Paul Mundt2007-07-20165-268/+247
| | | | | | | | | | | | | | Slab destructors were no longer supported after Christoph's c59def9f222d44bb7e2f0a559f2906191a0862d7 change. They've been BUGs for both slab and slub, and slob never supported them either. This rips out support for the dtor pointer from kmem_cache_create() completely and fixes up every single callsite in the kernel (there were about 224, not including the slab allocator definitions themselves, or the documentation references).

| * ide: add support for SCSI ioctls to ide-floppyBartlomiej Zolnierkiewicz2007-07-202-5/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that ide-floppy supports SG_IO we can add support for SCSI ioctls (except deprecated SCSI_IOCTL_SEND_COMMAND and legacy CDROM_SEND_PACKET ones - we can add them later iff really needed). While at it remove handling of CDROMEJECT and CDROMCLOSETRAY ioctls from generic_ide_ioctl(): - This prevents ide-{disk,tape,scsi} device drivers from obtaining REQ_TYPE_BLOCK_PC type requests which are currently unsupported by these drivers and which are potentially harmful (as reported by Andrew). - There is no functionality loss since aforementioned ioctls will now be handled by idefloppy_ioctl()->scsi_cmd_ioctl() (for devices using ide-floppy driver) and by idecd_ioctl->cdrom_ioctl()->scsi_cmd_ioctl() (for devices using ide-cd driver).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These changes will make NetLabel behave like labeled IPsec where there is an access check for both labeled and unlabeled packets as well as providing the ability to restrict domains to receiving only labeled packets when NetLabel is in use. The changes to the policy are straight forward with the following necessary to receive labeled traffic (with SECINITSID_NETMSG defined as "netlabel_peer_t"): allow mydom_t netlabel_peer_t:{ tcp_socket udp_socket rawip_socket } recvfrom; The policy for unlabeled traffic would be: allow mydom_t unlabeled_t:{ tcp_socket udp_socket rawip_socket } recvfrom; These policy changes, as well as more general NetLabel support, are included in the latest SELinux Reference Policy release 20070629 or later.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Create a new NetLabel KAPI interface, netlbl_enabled(), which reports on the current runtime status of NetLabel based on the existing configuration. LSMs that make use of NetLabel, i.e. SELinux, can use this new function to determine if they should perform NetLabel access checks. This patch changes the NetLabel/SELinux glue code such that SELinux only enforces NetLabel related access checks when netlbl_enabled() returns true. At present NetLabel is considered to be enabled when there is at least one labeled protocol configuration present. The result is that by default NetLabel is considered to be disabled, however, as soon as an administrator configured a CIPSO DOI definition NetLabel is enabled and SELinux starts enforcing NetLabel related access controls - including unlabeled packet controls. This patch also tries to consolidate the multiple "#ifdef CONFIG_NETLABEL" blocks into a single block to ease future review as recommended by Linus.

This is especially important when mmap is writing into holes as it allows filesystems to correctly account for and allocate space before the mmap write is allowed to proceed. Protection against truncate races is provided by locking the page and checking to see whether the page mapping is correct and whether it is beyond EOF so we don't end up allowing allocations beyond the current EOF or changing EOF as a result of a mmap write.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, CONFIG_X86_CMPXCHG64 both enables boot-time checking of the cmpxchg64b feature and enables compilation of the set_64bit() family. Since the option is dependent on PAE, and since KVM depends on set_64bit(), this effectively disables KVM on i386 nopae. Simplify by removing the config option altogether: the boot check is made dependent on CONFIG_X86_PAE directly, and the set_64bit() family is exposed without constraints. It is up to users to check for the feature flag (KVM does not as virtualiation extensions imply its existence).

| * | NFSv4: handle lack of clientaddr in option stringJeff Layton2007-07-191-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | If a NFSv4 mount is attempted with string based options, and the option string doesn't contain a clientaddr= option, the kernel will currently oops. Check for this situation and return a proper error. Signed-off-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

| | | | | | | | | | | | | | | | | | | | | | | | status in nfs client callback xdr code is passed in network order. print it in host order for better readability. Signed-off-by: Benny Halevy <bhalevy@panasas.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
| * | SUNRPC: Clean up the sillyrename codeTrond Myklebust2007-07-197-202/+120
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix a couple of bugs: - Don't rely on the parent dentry still being valid when the call completes. Fixes a race with shrink_dcache_for_umount_subtree() - Don't remove the file if the filehandle has been labelled as stale. Fix a couple of inefficiencies - Remove the global list of sillyrenamed files. Instead we can cache the sillyrename information in the dentry->d_fsdata - Move common code from unlink_setup/unlink_done into fs/nfs/unlink.c Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
| * | NFS: Introduce struct nfs_removeargs+nfs_removeresTrond Myklebust2007-07-197-64/+99
| | | | | | | | | | | | | | | | | | | | | We need a common structure for setting up an unlink() rpc call in order to fix the asynchronous unlink code. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
| * | NFS: Use dentry->d_time to store the parent directory verifier.Trond Myklebust2007-07-191-2/+2

| | | | | | | | | | | | | | | | | | | | | | | | | | | Since every invocation of xdr encode or decode functions takes the BKL now, there's a lot of redundant lock_kernel/unlock_kernel pairs that we can pull out into a common function.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Ensure that opendata->state is always initialised when we do state recovery. Ensure that we set the filehandle in the case where we're doing an "OPEN_CLAIM_PREVIOUS" call due to a server reboot. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
