* selinux: fix memory leak in sel_make_boolsXiaotian Feng2010-02-091-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | In sel_make_bools, kernel allocates memory for bool_pending_names[i] with security_get_bools. So if we just free bool_pending_names, those memories for bool_pending_names[i] will be leaked.

* syslog: distinguish between /proc/kmsg and syscallsKees Cook2010-02-044-7/+13
| | | | | | | | | | | | | | | This allows the LSM to distinguish between syslog functions originating from /proc/kmsg access and direct syscalls. By default, the commoncaps will now no longer require CAP_SYS_ADMIN to read an opened /proc/kmsg file descriptor. For example the kernel syslog reader can now drop privileges after opening /proc/kmsg, instead of staying privileged with CAP_SYS_ADMIN. MAC systems that implement security_syslog have unchanged behavior.

* TOMOYO: Remove usage counter for temporary memory.Tetsuo Handa2010-01-276-71/+29
| | | | | | | | | | | | TOMOYO was using own memory usage counter for detecting memory leak. But as kernel 2.6.31 introduced memory leak detection mechanism ( CONFIG_DEBUG_KMEMLEAK ), we no longer need to have own counter. We remove usage counter for memory used for permission checks, but we keep usage counter for memory used for policy so that we can apply quota.

* selinux: remove dead code in type_attribute_bounds_av()KaiGai Kohei2010-01-251-39/+4
| | | | | | | | | | | | | | | | | | | | | | This patch removes dead code in type_attribute_bounds_av(). Due to the historical reason, the type boundary feature is delivered from hierarchical types in libsepol, it has supported boundary features both of subject type (domain; in most cases) and target type. However, we don't have any actual use cases in bounded target types, and it tended to make conceptual confusion. So, this patch removes the dead code to apply boundary checks on the target types. I makes clear the TYPEBOUNDS restricts privileges of a certain domain bounded to any other domain.

Change the SELinux logic so that this case is handled as a typical permission denial, subject to the usual permissive mode and permissive domain handling. Also drop the 'requested' argument from security_compute_av() and helpers as it is a legacy of the original security server interface and is unused. Changes: - Handle permissive domains consistently by moving up the test for a permissive domain. - Make security_compute_av_user() consistent with security_compute_av(); the only difference now is that security_compute_av() performs mapping between the kernel-private class and permission indices and the policy values. In the userspace case, this mapping is handled by libselinux. - Moved avd_init inside the policy lock. Based in part on a patch by Paul Moore <paul.moore@hp.com>.

This confuses some applications, and does not conform to the man page for getxattr(2) etc., which state that these syscalls should return ENOTSUP if xattrs are not supported or disabled. Note that in the listsecurity case, we still need to return zero as we don't know which other xattr handlers may be active. For discussion of userland confusion, see: http://www.mail-archive.com/bug-coreutils@gnu.org/msg17988.html This patch corrects the error returns so that ENOTSUP is reported to userspace as required.

Goal is to transfert fields used at lookup time in the first read-mostly cache line (inside struct sock_common) and move sk_refcnt to a separate cache line (only written by rx path) This patch adds inet_ prefix to daddr, rcv_saddr, dport, num, saddr, sport and id fields. This allows a future patch to define these fields as macros, like sk_refcnt, without name clashes. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.
