2016-06-27netlabel: Add support for creating a CALIPSO protocol domain mapping.Huw Davies1-0/+3
This extends the NLBL_MGMT_C_ADD and NLBL_MGMT_C_ADDDEF commands to accept CALIPSO protocol DOIs. Signed-off-by: Huw Davies <huw@codeweavers.com> Signed-off-by: Paul Moore <paul@paul-moore.com>
2016-06-27netlabel: Add an address family to domain hash entries.Huw Davies1-5/+19
The reason is to allow different labelling protocols for different address families with the same domain. This requires the addition of an address family attribute in the netlink communication protocol. It is used in several messages: NLBL_MGMT_C_ADD and NLBL_MGMT_C_ADDDEF take it as an optional attribute for the unlabelled protocol. It may be one of AF_INET, AF_INET6 or AF_UNSPEC (to specify both address families). If it is missing, it defaults to AF_UNSPEC. NLBL_MGMT_C_LISTALL and NLBL_MGMT_C_LISTDEF return it as part of the enumeration of each item. Addtionally, it may be sent to LISTDEF to specify which address family to return.

2013-12-06netlabel: Fix FSF address in file headersJeff Kirsher1-2/+1
Several files refer to an old address for the Free Software Foundation in the file header comment. Resolve by replacing the address with the URL <http://www.gnu.org/licenses/> so that we do not have to keep updating the header comments anytime the address changes.

2008-10-10netlabel: Add network address selectors to the NetLabel/LSM domain mappingPaul Moore1-5/+54
This patch extends the NetLabel traffic labeling capabilities to individual packets based not only on the LSM domain but the by the destination address as well. The changes here only affect the core NetLabel infrastructre, changes to the NetLabel KAPI and individial protocol engines are also required but are split out into a different patch to ease review.

2008-01-30NetLabel: Remove unneeded RCU read locksPaul Moore1-4/+3
This patch removes some unneeded RCU read locks as we can treat the reads as "safe" even without RCU. It also converts the NetLabel configuration refcount from a spinlock protected u32 into atomic_t to be more consistent with the rest of the kernel.

2007-07-19SELinux: enable dynamic activation/deactivation of NetLabel/SELinux enforcementPaul Moore1-0/+5
Create a new NetLabel KAPI interface, netlbl_enabled(), which reports on the current runtime status of NetLabel based on the existing configuration. LSMs that make use of NetLabel, i.e. SELinux, can use this new function to determine if they should perform NetLabel access checks. This patch changes the NetLabel/SELinux glue code such that SELinux only enforces NetLabel related access checks when netlbl_enabled() returns true. At present NetLabel is considered to be enabled when there is at least one labeled protocol configuration present. The result is that by default NetLabel is considered to be disabled, however, as soon as an administrator configured a CIPSO DOI definition NetLabel is enabled and SELinux starts enforcing NetLabel related access controls - including unlabeled packet controls. This patch also tries to consolidate the multiple "#ifdef CONFIG_NETLABEL" blocks into a single block to ease future review as recommended by Linus.

2006-09-25[NetLabel]: rework the Netlink attribute handling (part 2)Paul Moore1-143/+68

2006-09-22[NetLabel]: core NetLabel subsystemPaul Moore1-0/+246
Add a new kernel subsystem, NetLabel, to provide explicit packet labeling services (CIPSO, RIPSO, etc.) to LSM developers. NetLabel is designed to work in conjunction with a LSM to intercept and decode security labels on incoming network packets as well as ensure that outgoing network packets are labeled according to the security mechanism employed by the LSM. The NetLabel subsystem is configured through a Generic NETLINK interface described in the header files included in this patch. Signed-off-by: Paul Moore <paul.moore@hp.com> Signed-off-by: David S.
