2008-04-30signals: cleanup security_task_kill() usage/implementationOleg Nesterov
Every implementation of ->task_kill() does nothing when the signal comes from the kernel. This is correct, but means that check_kill_permission() should call security_task_kill() only for SI_FROMUSER() case, and we can remove the same check from ->task_kill() implementations. (sadly, check_kill_permission() is the last user of signal->session/__session but we can't s/task_session_nr/task_session/ here). NOTE: Eric W. Biederman pointed out cap_task_kill() should die, and I think he is very right. Signed-off-by: Oleg Nesterov <oleg@tv-sign.ru> Cc: "Eric W.

2008-04-29keys: don't generate user and user session keyrings unless they're accessedDavid Howells
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).

2008-04-29keys: add keyctl function to get a security labelDavid Howells
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.

2008-04-28capabilities: implement per-process securebitsAndrew G. Morgan
Filesystem capability support makes it possible to do away with (set)uid-0 based privilege and use capabilities instead. That is, with filesystem support for capabilities but without this present patch, it is (conceptually) possible to manage a system with capabilities alone and never need to obtain privilege via (set)uid-0. Of course, conceptually isn't quite the same as currently possible since few user applications, certainly not enough to run a viable system, are currently prepared to leverage capabilities to exercise privilege. Further, many applications exist that may never get upgraded in this way, and the kernel will continue to want to support their setuid-0 base privilege needs. Where pure-capability applications evolve and replace setuid-0 binaries, it is desirable that there be a mechanisms by which they can contain their privilege. In addition to leveraging the per-process bounding and inheritable sets, this should include suppressing the privilege of the uid-0 superuser from the process' tree of children. The feature added by this patch can be leveraged to suppress the privilege associated with (set)uid-0. This suppression requires CAP_SETPCAP to initiate, and only immediately affects the 'current' process (it is inherited through fork()/exec()). This reimplementation differs significantly from the historical support for securebits which was system-wide, unwieldy and which has ultimately withered to a dead relic in the source of the modern kernel. With this patch applied a process, that is capable(CAP_SETPCAP), can now drop all legacy privilege (through uid=0) for itself and all subsequently fork()'d/exec()'d children with: prctl(PR_SET_SECUREBITS, 0x2f); This patch represents a no-op unless CONFIG_SECURITY_FILE_CAPABILITIES is enabled at configure time.

2008-04-28Audit: standardize string audit interfacesEric Paris
This patch standardized the string auditing interfaces. No userspace changes will be visible and this is all just cleanup and consistancy work. We have the following string audit interfaces to use: void audit_log_n_hex(struct audit_buffer *ab, const unsigned char *buf, size_t len); void audit_log_n_string(struct audit_buffer *ab, const char *buf, size_t n); void audit_log_string(struct audit_buffer *ab, const char *buf); void audit_log_n_untrustedstring(struct audit_buffer *ab, const char *string, size_t n); void audit_log_untrustedstring(struct audit_buffer *ab, const char *string); This may be the first step to possibly fixing some of the issues that people have with the string output from the kernel audit system. But we still don't have an agreed upon solution to that problem. Signed-off-by: Eric Paris <eparis@redhat.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

The Fedora installer actually makes multiple NFS mounts before it loads selinux policy. The code in selinux_clone_mnt_opts() assumed that the init process would always be loading policy before NFS was up and running.

2008-04-19Security: Introduce security= boot parameterAhmed S. Darwish
Add the security= boot parameter. This is done to avoid LSM registration clashes in case of more than one bult-in module. User can choose a security module to enable at boot. If no security= boot parameter is specified, only the first LSM asking for registration will be loaded. An invalid security module name will be treated as if no module has been chosen. LSM modules must check now if they are allowed to register by calling security_module_enable(ops) first. Modify SELinux and SMACK to do so. Do not let SMACK register smackfs if it was not chosen on boot. Smackfs assumes that smack hooks are registered and the initial task security setup (swapper->security) is done.

2008-04-19SELinux: use new audit hooks, remove redundant exportsAhmed S. Darwish
Setup the new Audit LSM hooks for SELinux. Remove the now redundant exported SELinux Audit interface. Audit: Export 'audit_krule' and 'audit_field' to the public since their internals are needed by the implementation of the new LSM hook 'audit_rule_known'.
