2016-07-12apparmor: fix replacement bug that adds new child to old parentJohn Johansen1-1/+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.

2016-07-07samples/seccomp: Add standalone config optionOlof Johansson2-1/+8
Add a separate Kconfig option for SAMPLES_SECCOMP. Main reason for this is that, just like other samples, it's forced to be a module. Without this, since the sample is a target only controlled by CONFIG_SECCOMP_FILTER, the samples will be built before include files are put in place properly. For example, from an arm64 allmodconfig built with "make -sk -j 32" (without specific target), the following happens: samples/seccomp/bpf-fancy.c:13:27: fatal error: linux/seccomp.h: No such file or directory samples/seccomp/bpf-helper.h:20:50: fatal error: linux/seccomp.h: No such file or directory samples/seccomp/dropper.c:20:27: fatal error: linux/seccomp.h: No such file or directory samples/seccomp/bpf-direct.c:21:27: fatal error: linux/seccomp.h: No such file or directory So, just stick to the same format as other samples.

2016-06-30ima: extend the measurement entry specific pcrEric Richter1-3/+3
Extend the PCR supplied as a parameter, instead of assuming that the measurement entry uses the default configured PCR. Signed-off-by: Eric Richter <erichte@linux.vnet.ibm.com> Signed-off-by: Mimi Zohar <zohar@linux.vnet.ibm.com>
2016-06-30ima: change integrity cache to store measured pcrEric Richter3-3/+11
IMA avoids re-measuring files by storing the current state as a flag in the integrity cache. It will then skip adding a new measurement log entry if the cache reports the file as already measured. If a policy measures an already measured file to a new PCR, the measurement will not be added to the list. This patch implements a new bitfield for specifying which PCR the file was measured into, rather than if it was measured.

2016-06-30ima: redefine duplicate template entriesEric Richter1-3/+4
Template entry duplicates are prevented from being added to the measurement list by checking a hash table that contains the template entry digests. However, the PCR value is not included in this comparison, so duplicate template entry digests with differing PCRs may be dropped. This patch redefines duplicate template entries as template entries with the same digest and same PCR values.

2016-06-30ima: change ima_measurements_show() to display the entry specific pcrEric Richter1-5/+4
IMA assumes that the same default Kconfig PCR is extended for each entry. This patch replaces the default configured PCR with the policy defined PCR. Signed-off-by: Eric Richter <erichte@linux.vnet.ibm.com> Signed-off-by: Mimi Zohar <zohar@linux.vnet.ibm.com>
2016-06-30ima: include pcr for each measurement log entryEric Richter4-8/+13
The IMA measurement list entries include the Kconfig defined PCR value. This patch defines a new ima_template_entry field for including the PCR as specified in the policy rule. Signed-off-by: Eric Richter <erichte@linux.vnet.ibm.com> Signed-off-by: Mimi Zohar <zohar@linux.vnet.ibm.com>
2016-06-30ima: extend ima_get_action() to return the policy pcrEric Richter5-7/+14
Different policy rules may extend different PCRs. This patch retrieves the specific PCR for the matched rule. Subsequent patches will include the rule specific PCR in the measurement list and extend the appropriate PCR.

2016-06-30ima: add policy support for extending different pcrsEric Richter1-1/+28
This patch defines a new IMA measurement policy rule option "pcr=", which allows extending different PCRs on a per rule basis. For example, the system independent files could extend the default IMA Kconfig specified PCR, while the system dependent files could extend a different PCR. The following is an example of this usage with an SELinux policy; the rule would extend PCR 11 with system configuration files: measure func=FILE_CHECK mask=MAY_READ obj_type=system_conf_t pcr=11 Changelog v3: - FIELD_SIZEOF returns bytes, not bits.

2016-06-30integrity: add measured_pcrs field to integrity cacheEric Richter2-0/+3
To keep track of which measurements have been extended to which PCRs, this patch defines a new integrity_iint_cache field named measured_pcrs. This field is a bitmask of the PCRs measured. Each bit corresponds to a PCR index. For example, bit 10 corresponds to PCR 10. Signed-off-by: Eric Richter <erichte@linux.vnet.ibm.com> Signed-off-by: Mimi Zohar <zohar@linux.vnet.ibm.com>
2016-06-27netlabel: Implement CALIPSO config functions for SMACK.Huw Davies4-0/+238
SMACK uses similar functions to control CIPSO, these are the equivalent functions for CALIPSO and follow exactly the same semantics. int netlbl_cfg_calipso_add(struct calipso_doi *doi_def, struct netlbl_audit *audit_info) Adds a CALIPSO doi. void netlbl_cfg_calipso_del(u32 doi, struct netlbl_audit *audit_info) Removes a CALIPSO doi. int netlbl_cfg_calipso_map_add(u32 doi, const char *domain, const struct in6_addr *addr, const struct in6_addr *mask, struct netlbl_audit *audit_info) Creates a mapping between a domain and a CALIPSO doi. If addr and mask are non-NULL this creates an address-selector type mapping. This also extends netlbl_cfg_map_del() to remove IPv6 address-selector mappings.

2016-06-27calipso: Add a label cache.Huw Davies8-12/+360
This works in exactly the same way as the CIPSO label cache. 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.

2016-06-27calipso: Add validation of CALIPSO option.Huw Davies3-0/+74
Lengths, checksum and the DOI are checked. Checking of the level and categories are left for the socket layer. CRC validation is performed in the calipso module to avoid unconditionally linking crc_ccitt() into ipv6.

2016-06-27netlabel: Pass a family parameter to netlbl_skbuff_err().Huw Davies6-12/+19
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. Signed-off-by: Huw Davies <huw@codeweavers.com> Signed-off-by: Paul Moore <paul@paul-moore.com>
2016-06-27calipso: Allow the lsm to label the skbuff directly.Huw Davies6-4/+308
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.

2016-06-27calipso: Allow request sockets to be relabelled by the lsm.Huw Davies6-8/+163
Request sockets need to have a label that takes into account the incoming connection as well as their parent's label. This is used for the outgoing SYN-ACK and for their child full-socket. Signed-off-by: Huw Davies <huw@codeweavers.com> Signed-off-by: Paul Moore <paul@paul-moore.com>
2016-06-27ipv6: Allow request socks to contain IPv6 options.Huw Davies4-7/+27
If set, these will take precedence over the parent's options during both sending and child creation. If they're not set, the parent's options (if any) will be used. This is to allow the security_inet_conn_request() hook to modify the IPv6 options in just the same way that it already may do for IPv4.

2016-06-27netlabel: Prevent setsockopt() from changing the hop-by-hop option.Huw Davies1-1/+16
If a socket has a netlabel in place then don't let setsockopt() alter the socket's IPv6 hop-by-hop option. This is in the same spirit as the existing check for IPv4. Signed-off-by: Huw Davies <huw@codeweavers.com> Signed-off-by: Paul Moore <paul@paul-moore.com>
2016-06-27calipso: Set the calipso socket label to match the secattr.Huw Davies10-10/+728
CALIPSO is a hop-by-hop IPv6 option. A lot of this patch is based on the equivalent CISPO code. The main difference is due to manipulating the options in the hop-by-hop header. Signed-off-by: Huw Davies <huw@codeweavers.com> Signed-off-by: Paul Moore <paul@paul-moore.com>

2016-06-27netlabel: Initial support for the CALIPSO netlink protocol.Huw Davies12-2/+604
CALIPSO is a packet labelling protocol for IPv6 which is very similar to CIPSO. It is specified in RFC 5570. Much of the code is based on the current CIPSO code. This adds support for adding passthrough-type CALIPSO DOIs through the NLBL_CALIPSO_C_ADD command. It requires attributes: NLBL_CALIPSO_A_TYPE which must be CALIPSO_MAP_PASS. NLBL_CALIPSO_A_DOI. In passthrough mode the CALIPSO engine will map MLS secattr levels and categories directly to the packet label. At this stage, the major difference between this and the CIPSO code is that IPv6 may be compiled as a module. To allow for this the CALIPSO functions are registered at module init time.

2016-06-27netlabel: Add an address family to domain hash entries.Huw Davies6-58/+192
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.

This splits tpm_tis in a high-level protocol part and a low-level interface for the actual TPM communication. The low-level interface can then be implemented by additional drivers to provide access to TPMs using other mechanisms, for example native I2C or SPI transfers, while still reusing the same TIS protocol implementation. Though the ioread/iowrite calls cannot fail, other implementations of this interface might want to return error codes if their communication fails. This follows the usual pattern of negative values representing errors and zero representing success. Positive values are not used (yet). Errors are passed back to the caller if possible. If the interface of a function does not allow that, it tries to do the most sensible thing it can, but this might also mean ignoring the error in this instance. This commit is based on the initial work by Peter Huewe.

2016-06-25tpm: tpm_tis: Share common data between physChristophe Ricard2-76/+132
Split priv_data structure in common and phy specific structures. This will allow in future patches to reuse the same tis logic on top of new phy such as spi and i2c. Ultimately, other drivers may reuse this tis logic. (e.g: st33zp24...) iobase field is specific to TPM addressed on 0xFED4xxxx on LPC/SPI bus. This commit is based on the initial work by Peter Huewe.

Fix the suspend regression due to the wrong way of retrieving the chip structure. The suspend functions are attached to the hardware device, not the chip and thus must rely on drvdata.
