* selinux: fix error return code in policydb_read()Wei Yongjun2016-09-131-0/+1
| | | | | | | | | | Fix to return error code -EINVAL from the error handling case instead of 0 (rc is overwrite to 0 when policyvers >= POLICYDB_VERSION_ROLETRANS), as done elsewhere in this function.

* selinux: detect invalid ebitmapWilliam Roberts2016-08-291-0/+3
| | | | | | | | | | | When count is 0 and the highbit is not zero, the ebitmap is not valid and the internal node is not allocated. This causes issues when routines, like mls_context_isvalid() attempt to use the ebitmap_for_each_bit() and ebitmap_node_get_bit() as they assume a highbit > 0 will have a node allocated.

* security, overlayfs: Provide hook to correctly label newly created filesVivek Goyal2016-08-081-0/+11
| | | | | | | | | | | | | | | | | | | | | | During a new file creation we need to make sure new file is created with the right label. New file is created in upper/ so effectively file should get label as if task had created file in upper/. We switched to mounter's creds for actual file creation. Also if there is a whiteout present, then file will be created in work/ dir first and then renamed in upper. In none of the cases file will be labeled as we want it to be. This patch introduces a new hook dentry_create_files_as(), which determines the label/context dentry will get if it had been created by task in upper and modify passed set of creds appropriately. Caller makes use of these new creds for file creation.

| | | | | | | | | | | Right now selinux_determine_inode_label() works on security pointer of current task. Soon I need this to work on a security pointer retrieved from a set of creds.

* selinux: Implementation for inode_copy_up_xattr() hookVivek Goyal2016-08-081-0/+16
| | | | | | | | | | | | When a file is copied up in overlay, we have already created file on upper/ with right label and there is no need to copy up selinux label/xattr from lower file to upper file. In fact in case of context mount, we don't want to copy up label as newly created file got its label from context= option.

| | | | | | | | | | | | | | | Provide a security hook which is called when xattrs of a file are being copied up. This hook is called once for each xattr and LSM can return 0 if the security module wants the xattr to be copied up, 1 if the security module wants the xattr to be discarded on the copy, -EOPNOTSUPP if the security module does not handle/manage the xattr, or a -errno upon an error.

| | | | | | | | | | | | | | | A file is being copied up for overlay file system. Prepare a new set of creds and set create_sid appropriately so that new file is created with appropriate label. Overlay inode has right label for both context and non-context mount cases. In case of non-context mount, overlay inode will have the label of lower file and in case of context mount, overlay inode will have the label from context= mount option.

Another minor problem with the original patch is that the option is even offered in sysfs when SECURITY_APPARMOR_HASH is not enabled, so this also hides the option in that case.

The only other example of a AppArmor mediating access to another, already running, task (ignoring fork+exec) is ptrace. The AppArmor model for ptrace is that one of the following must be true: 1) The tracer is unconfined 2) The tracer is in complain mode 3) The tracer and tracee are confined by the same profile 4) The tracer is confined but has SYS_CAP_PTRACE 1), 2, and 3) are already true for setrlimit. We can match the ptrace model just by allowing CAP_SYS_RESOURCE. We still test the values of the rlimit since it can always be overridden using a value that means unlimited for a particular resource.

| * | apparmor: fix replacement bug that adds new child to old parentJohn Johansen2016-07-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When set atomic replacement is used and the parent is updated before the child, and the child did not exist in the old parent so there is no direct replacement then the new child is incorrectly added to the old parent. This results in the new parent not having the child(ren) that it should and the old parent when being destroyed asserting the following error.

| | * | | Smack: ignore null signal in smack_task_killRafal Krypa2016-06-081-0/+3
| | |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Kill with signal number 0 is commonly used for checking PID existence. Smack treated such cases like any other kills, although no signal is actually delivered when sig == 0. Checking permissions when sig == 0 didn't prevent an unprivileged caller from learning whether PID exists or not. When it existed, kernel returned EPERM, when it didn't - ESRCH. The only effect of policy check in such case is noise in audit logs. This change lets Smack silently ignore kill() invocations with sig == 0.

| | * | | calipso: Add a label cache.Huw Davies2016-06-271-3/+6

The idea is to allow the lsm to cache the result of a secattr lookup so that it doesn't need to perform the lookup for every skbuff. It introduces two sysctl controls: calipso_cache_enable - enables/disables the cache. calipso_cache_bucket_size - sets the size of a cache bucket.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This makes it possible to route the error to the appropriate labelling engine. CALIPSO is far less verbose than CIPSO when encountering a bogus packet, so there is no need for a CALIPSO error handler.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In some cases, the lsm needs to add the label to the skbuff directly. A NF_INET_LOCAL_OUT IPv6 hook is added to selinux to match the IPv4 behaviour. This allows selinux to label the skbuffs that it requires.
