* SELinux: calculate and print hashtab stats with a generic functionEric Paris2011-04-281-19/+13
| | | | | | | | | We have custom debug functions like rangetr_hash_eval and symtab_hash_eval which do the same thing. Just create a generic function that takes the name of the hash table as an argument instead of having custom functions.

* SELinux: skip filename trans rules if ttype does not match parent dirEric Paris2011-04-283-0/+17
| | | | | | | | | | | | | | Right now we walk to filename trans rule list for every inode that is created. First passes at policy using this facility creates around 5000 filename trans rules. Running a list of 5000 entries every time is a bad idea. This patch adds a new ebitmap to policy which has a bit set for each ttype that has at least 1 filename trans rule. Thus when an inode is created we can quickly determine if any rules exist for this parent directory type and can skip the list if we know there is definitely no relevant entry.

* SELINUX: Make selinux cache VFS RCU walks safeEric Paris2011-04-253-25/+55
| | | | | | | | | | | | | | | | Now that the security modules can decide whether they support the dcache RCU walk or not it's possible to make selinux a bit more RCU friendly. The SELinux AVC and security server access decision code is RCU safe. A specific piece of the LSM audit code may not be RCU safe. This patch makes the VFS RCU walk retry if it would hit the non RCU safe chunk of code. It will normally just work under RCU. This is done simply by passing the VFS RCU state as a flag down into the avc_audit() code and returning ECHILD there if it would have an issue.

This is because security_inode_exec_permission unconditionally fails RCU walks. Move this decision to the low level security module. This requires passing the RCU flags down the security hook.

| | | | | | | | | | | | | | | | | | | | For SELinux we do not allow security information to change during a remount operation.

| * LSM: Pass -o remount options to the LSMEric Paris2011-03-034-0/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The VFS mount code passes the mount options to the LSM. The LSM will remove options it understands from the data and the VFS will then pass the remaining options onto the underlying filesystem. This is how options like the SELinux context= work. The problem comes in that -o remount never calls into LSM code. So if you include an LSM specific option it will get passed to the filesystem and will cause the remount to fail. An example of where this is a problem is the 'seclabel' option. The SELinux LSM hook will print this word in /proc/mounts if the filesystem is being labeled using xattrs. If you pass this word on mount it will be silently stripped and ignored. But if you pass this word on remount the LSM never gets called and it will be passed to the FS. The FS doesn't know what seclabel means and thus should fail the mount. For example an ext3 fs mounted over loop # mount -o loop /tmp/fs /mnt/tmp # cat /proc/mounts | grep /mnt/tmp /dev/loop0 /mnt/tmp ext3 rw,seclabel,relatime,errors=continue,barrier=0,data=ordered 0 0 # mount -o remount /mnt/tmp mount: /mnt/tmp not mounted already, or bad option # dmesg EXT3-fs (loop0): error: unrecognized mount option "seclabel" or missing value This patch passes the remount mount options to an new LSM hook.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit 242631c49d4cf39642741d6627750151b058233b. Conflicts: security/selinux/hooks.c SELinux used to recognize certain individual ioctls and check permissions based on the knowledge of the individual ioctl. In commit 242631c49d4cf396 the SELinux code stopped trying to understand individual ioctls and to instead looked at the ioctl access bits to determine in we should check read or write for that operation. This same suggestion was made to SMACK (and I believe copied into TOMOYO). But this suggestion is total rubbish. The ioctl access bits are actually the access requirements for the structure being passed into the ioctl, and are completely unrelated to the operation of the ioctl or the object the ioctl is being performed upon. Take FS_IOC_FIEMAP as an example. FS_IOC_FIEMAP is defined as: FS_IOC_FIEMAP _IOWR('f', 11, struct fiemap) So it has access bits R and W. What this really means is that the kernel is going to both read and write to the struct fiemap. It has nothing at all to do with the operations that this ioctl might perform on the file itself!

With this patch: * we don't mark /proc/sys/ inodes as private * we don't need the sysclt security hook * we walk the dentry tree to find the path to the inode. We have to strip the PID in /proc/PID/ entries that have a proc_dir_entry because selinux does not know how to label paths like '/1/net/rpc/nfsd.fh' (and defaults to 'proc_t' labeling). Selinux does know of '/net/rpc/nfsd.fh' (and applies the 'sysctl_rpc_t' label). PID stripping from the path was done implicitly in the previous code because the proc_dir_entry tree had the root in '/net' in the example from above. The dentry tree has the root in '/1'.

| * SELinux: Use dentry name in new object labelingEric Paris2011-02-016-37/+197
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently SELinux has rules which label new objects according to 3 criteria. The label of the process creating the object, the label of the parent directory, and the type of object (reg, dir, char, block, etc.) This patch adds a 4th criteria, the dentry name, thus we can distinguish between creating a file in an etc_t directory called shadow and one called motd. There is no file globbing, regex parsing, or anything mystical. Either the policy exactly (strcmp) matches the dentry name of the object or it doesn't. This patch has no changes from today if policy does not implement the new rules. Signed-off-by: Eric Paris <eparis@redhat.com>
| * fs/vfs/security: pass last path component to LSM on inode creationEric Paris2011-02-0139-94/+136
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 <eparis@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 34xx and 3590 tape driver uses the system work queue to defer work from the interrupt function to process context, e.g. a medium sense after an unsolicited interrupt. The tape commands started by the work handler need to be asynchronous, otherwise a deadlock on the system work queue can occur. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The "ct" variable should be an unsigned int. Both struct kbdiacrs ->kb_cnt and struct kbd_data ->accent_table_size are unsigned ints. Making it signed causes a problem in KBDIACRUC because the user could set the signed bit and cause a buffer overflow.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The module parameter 'devs' and 'sizes' are marked as __initdata. The memory for the parameters are freed after module_init completed. This can lead to kernel crashes in param_free_charp. Remove the __initdata attribute to fix the problem.
