This patch defines a new template called 'ima-sig', which includes the file signature in the template data, in addition to the file's digest and pathname. A template is composed of a set of fields. Associated with each field is an initialization and display function. This patch defines a new template field called 'sig', the initialization function ima_eventsig_init(), and the display function ima_show_template_sig(). This patch modifies the .field_init() function definition to include the 'security.ima' extended attribute and length. Changelog: - remove unused code (Dmitry Kasatkin) - avoid calling ima_write_template_field_data() unnecesarily (Roberto Sassu) - rename DATA_FMT_SIG to DATA_FMT_HEX - cleanup ima_eventsig_init() based on Roberto's comments Signed-off-by:

If a macro is only used within 2 times, and also its contents are within 2 lines, recommend to expand it to shrink code line. For our case, the macro is not portable either: some architectures' assembler may use another character to mark newline in a macro (e.g. '`' for arc), which will cause issue. If still want to use macro and let it portable enough, it will also need include additional header file (e.g "#include <linux/linkage.h>", although it also need be fixed). Signed-off-by:

If a key is displaced from a keyring by a matching one, then four more bytes of quota are allocated to the keyring - despite the fact that the keyring does not change in size. Further, when a key is unlinked from a keyring, the four bytes of quota allocated the link isn't recovered and returned to the user's pool. The first can be tested by repeating: keyctl add big_key a fred @s cat /proc/key-users (Don't put it in a shell loop otherwise the garbage collector won't have time to clear the displaced keys, thus affecting the result). This was causing the kerberos keyring to run out of room fairly quickly. The second can be tested by: cat /proc/key-users a=`keyctl add user a a @s` cat /proc/key-users keyctl unlink $a sleep 1 # Give RCU a chance to delete the key cat /proc/key-users assuming no system activity that otherwise adds/removes keys, the amount of key data allocated should go up (say 40/20000 -> 47/20000) and then return to the original value at the end.

key_reject_and_link() marking a key as negative and setting the error with which it was negated races with keyring searches and other things that read that error. The fix is to switch the order in which the assignments are done in key_reject_and_link() and to use memory barriers.

The IMA measurement list contains two hashes - a template data hash and a filedata hash. The template data hash is committed to the TPM, which is limited, by the TPM v1.2 specification, to 20 bytes. The filedata hash is defined as 20 bytes as well. Now that support for variable length measurement list templates was added, the filedata hash is not limited to 20 bytes. This patch adds Kconfig support for defining larger default filedata hash algorithms and replacing the builtin default with one specified on the kernel command line. <uapi/linux/hash_info.h> contains a list of hash algorithms. The Kconfig default hash algorithm is a subset of this list, but any hash algorithm included in the list can be specified at boot, using the 'ima_hash=' kernel command line option. Changelog v2: - update Kconfig Changelog: - support hashes that are configured - use generic HASH_ALGO_ definitions - add Kconfig support - hash_setup must be called only once (Dmitry) - removed trailing whitespaces (Roberto Sassu) Signed-off-by:

The same hash algorithm should be used for calculating the file data hash for the IMA measurement list, as for appraising the file data integrity. (The appraise hash algorithm is stored in the 'security.ima' extended attribute.) The exception is when the reference file data hash digest, stored in the extended attribute, is larger than the one supported by the template. In this case, the file data hash needs to be calculated twice, once for the measurement list and, again, for appraisal. Signed-off-by:

This patch performs the switch to the new template mechanism by modifying the functions ima_alloc_init_template(), ima_measurements_show() and ima_ascii_measurements_show(). The old function ima_template_show() was removed as it is no longer needed. Also, if the template descriptor used to generate a measurement entry is not 'ima', the whole length of field data stored for an entry is provided before the data itself through the binary_runtime_measurement interface.

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: [<hash algo>:]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.

The new function allocates and initializes the measurement entry with the inode digest and the filename. In respect to the current behavior, it truncates the file name passed in the 'filename' argument if the latter's size is greater than 255 bytes and the passed file descriptor is NULL.
