Smack: adds smackfs/ptrace interface

2014-04-11T21:34:35Z

This allows to limit ptrace beyond the regular smack access rules. It adds a smackfs/ptrace interface that allows smack to be configured to require equal smack labels for PTRACE_MODE_ATTACH access. See the changes in Documentation/security/Smack.txt below for details. Signed-off-by: Lukasz Pawelczyk Signed-off-by: Rafal Krypa

ima: update IMA-templates.txt documentation

2014-01-03T12:42:59Z

Patch "ima: extend the measurement list to include the file signature" defined a new field called 'sig' and a new template called 'ima-sig'. This patch updates the Documentation/security/IMA-templates.txt.

ima: new templates management mechanism

2013-10-25T21:17:04Z

The original 'ima' template is fixed length, containing the filedata hash and pathname. The filedata hash is limited to 20 bytes (md5/sha1). The pathname is a null terminated string, limited to 255 characters. To overcome these limitations and to add additional file metadata, it is necessary to extend the current version of IMA by defining additional templates. The main reason to introduce this feature is that, each time a new template is defined, the functions that generate and display the measurement list would include the code for handling a new format and, thus, would significantly grow over time. This patch set solves this problem by separating the template management from the remaining IMA code. The core of this solution is the definition of two new data structures: a template descriptor, to determine which information should be included in the measurement list, and a template field, to generate and display data of a given type. To define a new template field, developers define the field identifier and implement two functions, init() and show(), respectively to generate and display measurement entries. Initially, this patch set defines the following template fields (support for additional data types will be added later): - 'd': the digest of the event (i.e. the digest of a measured file), calculated with the SHA1 or MD5 hash algorithm; - 'n': the name of the event (i.e. the file name), with size up to 255 bytes; - 'd-ng': the digest of the event, calculated with an arbitrary hash algorithm (field format: [:]digest, where the digest prefix is shown only if the hash algorithm is not SHA1 or MD5); - 'n-ng': the name of the event, without size limitations. Defining a new template descriptor requires specifying the template format, a string of field identifiers separated by the '|' character. This patch set defines the following template descriptors: - "ima": its format is 'd|n'; - "ima-ng" (default): its format is 'd-ng|n-ng' Further details about the new template architecture can be found in Documentation/security/IMA-templates.txt.

KEYS: Define a __key_get() wrapper to use rather than atomic_inc()

Define a __key_get() wrapper to use rather than atomic_inc() on the key usage count as this makes it easier to hook in refcount error debugging. Signed-off-by: David Howells

Smack: add support for modification of existing rules

2013-03-19T21:16:42Z

Rule modifications are enabled via /smack/change-rule. Format is as follows: "Subject Object rwaxt rwaxt" First two strings are subject and object labels up to 255 characters. Third string contains permissions to enable. Fourth string contains permissions to disable. All unmentioned permissions will be left unchanged. If no rule previously existed, it will be created.
