Remove proc_root export. Creation and removal works well if parent PDE is supplied as NULL -- it worked always that way. So, one useless export removed and consistency added, some drivers created PDEs with &proc_root as parent but removed them as NULL and so on. Signed-off-by:

proc-misc code is noticeably full of "if (de)" checks when PDE passed is always valid. Remove them. Addition of such check in proc_lookup_de() is for failed lookup case. Signed-off-by:

If valid "parent" is passed to proc_create/remove_proc_entry(), then name of PDE should consist of only one path component, otherwise creation or or removal will fail. However, if NULL is passed as parent then create/remove accept full path as a argument. This is arbitrary restriction -- all infrastructure is in place. So, patch allows the following to succeed: create_proc_entry("foo/bar", 0, pde_baz); remove_proc_entry("baz/foo/bar", &proc_root); Also makes the following to behave identically: create_proc_entry("foo/bar", 0, NULL); create_proc_entry("foo/bar", 0, &proc_root); Discrepancy noticed by Den Lunev (IIRC).

proc_subdir_lock protects only modifying and walking through PDE lists, so after we've found PDE to remove and actually removed it from lists, there is no need to hold proc_subdir_lock for the rest of operation. Signed-off-by:

This cleans up the permission checks done for /proc/PID/mem i/o calls. It puts all the logic in a new function, check_mem_permission(). The old code repeated the (!MAY_PTRACE(task) || !ptrace_may_attach(task)) magical expression multiple times. The new function does all that work in one place, with clear comments. The old code called security_ptrace() twice on successful checks, once in MAY_PTRACE() and once in __ptrace_may_attach(). Now it's only called once, and only if all other checks have succeeded.

The kernel implements readlink of /proc/pid/exe by getting the file from the first executable VMA. Then the path to the file is reconstructed and reported as the result. Because of the VMA walk the code is slightly different on nommu systems. This patch avoids separate /proc/pid/exe code on nommu systems. Instead of walking the VMAs to find the first executable file-backed VMA we store a reference to the exec'd file in the mm_struct. That reference would prevent the filesystem holding the executable file from being unmounted even after unmapping the VMAs. So we track the number of VM_EXECUTABLE VMAs and drop the new reference when the last one is unmapped. This avoids pinning the mounted filesystem.

Make the keyring quotas controllable through /proc/sys files: (*) /proc/sys/kernel/keys/root_maxkeys /proc/sys/kernel/keys/root_maxbytes Maximum number of keys that root may have and the maximum total number of bytes of data that root may have stored in those keys. (*) /proc/sys/kernel/keys/maxkeys /proc/sys/kernel/keys/maxbytes Maximum number of keys that each non-root user may have and the maximum total number of bytes of data that each of those users may have stored in their keys. Also increase the quotas as a number of people have been complaining that it's not big enough. I'm not sure that it's big enough now either, but on the other hand, it can now be set in /etc/sysctl.conf. Signed-off-by: -

Don't generate the per-UID user and user session keyrings unless they're explicitly accessed. This solves a problem during a login process whereby set*uid() is called before the SELinux PAM module, resulting in the per-UID keyrings having the wrong security labels. This also cures the problem of multiple per-UID keyrings sometimes appearing due to PAM modules (including pam_keyinit) setuiding and causing user_structs to come into and go out of existence whilst the session keyring pins the user keyring. This is achieved by first searching for extant per-UID keyrings before inventing new ones. The serial bound argument is also dropped from find_keyring_by_name() as it's not currently made use of (setting it to 0 disables the feature). Signed-off-by:

The key_create_or_update() function provided by the keyring code has a default set of permissions that are always applied to the key when created. This might not be desirable to all clients. Here's a patch that adds a "perm" parameter to the function to address this, which can be set to KEY_PERM_UNDEF to revert to the current behaviour. Signed-off-by:

Add a keyctl() function to get the security label of a key. The following is added to Documentation/keys.txt: (*) Get the LSM security context attached to a key. long keyctl(KEYCTL_GET_SECURITY, key_serial_t key, char *buffer, size_t buflen) This function returns a string that represents the LSM security context attached to a key in the buffer provided. Unless there's an error, it always returns the amount of data it could produce, even if that's too big for the buffer, but it won't copy more than requested to userspace. If the buffer pointer is NULL then no copy will take place. A NUL character is included at the end of the string if the buffer is sufficiently big. This is included in the returned count. If no LSM is in force then an empty string will be returned. A process must have view permission on the key for this function to be successful.

Check the starting keyring as part of the search to (a) see if that is what we're searching for, and (b) to check it is still valid for searching. The scenario: User in process A does things that cause things to be created in its process session keyring. The user then does an su to another user and starts a new process, B. The two processes now share the same process session keyring. Process B does an NFS access which results in an upcall to gssd. When gssd attempts to instantiate the context key (to be linked into the process session keyring), it is denied access even though it has an authorization key. The order of calls is: keyctl_instantiate_key() lookup_user_key() (the default: case) search_process_keyrings(current) search_process_keyrings(rka->context) (recursive call) keyring_search_aux() keyring_search_aux() verifies the keys and keyrings underneath the top-level keyring it is given, but that top-level keyring is neither fully validated nor checked to see if it is the thing being searched for. This patch changes keyring_search_aux() to: 1) do more validation on the top keyring it is given and 2) check whether that top-level keyring is the thing being searched for Signed-off-by:Kevin Coffman <kwc@citi.umich.edu> Signed-off-by:

Increase the size of a payload that can be used to instantiate a key in add_key() and keyctl_instantiate_key(). This permits huge CIFS SPNEGO blobs to be passed around. The limit is raised to 1MB. If kmalloc() can't allocate a buffer of sufficient size, vmalloc() will be tried instead. Signed-off-by:
