Pull implicit module.h fixes from Paul Gortmaker: "Fix up implicit users that will break later. The files changed here are simply modular source files that are implicitly relying on being present. We fix them up now, so that we can decouple some of the module related init code from the core init code in the future. The addition of the module.h include to several files here is also a no-op from a code generation point of view, else there would already be compile issues with these files today. There may be lots more implicit includes of in tree, but these are the ones that extensive build test coverage has shown that must be fixed in order to avoid build breakage fallout for the pending module.h <---> init.h code relocation we desire to complete" * tag 'module-implicit-v4.1-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux: frv: add module.h to mb93090-mb00/flash.c to avoid compile fail drivers/cpufreq: include for modular exynos-cpufreq.c code drivers/staging: include for modular android tegra_ion code crypto/asymmetric_keys: pkcs7_key_type needs module.h sh: mach-highlander/psw.c is tristate and should use module.h drivers/regulator: include for modular max77802 code drivers/pcmcia: include for modular xxs1500_ss code drivers/hsi: include for modular omap_ssi code drivers/gpu: include for modular rockchip code drivers/gpio: include for modular crystalcove code drivers/clk: include for clk-max77xxx modular code

Pull security subsystem updates from James Morris: "The main change in this kernel is Casey's generalized LSM stacking work, which removes the hard-coding of Capabilities and Yama stacking, allowing multiple arbitrary "small" LSMs to be stacked with a default monolithic module (e.g. SELinux, Smack, AppArmor). See https://lwn.net/Articles/636056/ This will allow smaller, simpler LSMs to be incorporated into the mainline kernel and arbitrarily stacked by users. Also, this is a useful cleanup of the LSM code in its own right" * 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security: (38 commits) tpm, tpm_crb: fix le64_to_cpu conversions in crb_acpi_add() vTPM: set virtual device before passing to ibmvtpm_reset_crq tpm_ibmvtpm: remove unneccessary message level. ima: update builtin policies ima: extend "mask" policy matching support ima: add support for new "euid" policy condition ima: fix ima_show_template_data_ascii() Smack: freeing an error pointer in smk_write_revoke_subj() selinux: fix setting of security labels on NFS selinux: Remove unused permission definitions selinux: enable genfscon labeling for sysfs and pstore files selinux: enable per-file labeling for debugfs files. selinux: update netlink socket classes signals: don't abuse __flush_signals() in selinux_bprm_committed_creds() selinux: Print 'sclass' as string when unrecognized netlink message occurs Smack: allow multiple labels in onlycap Smack: fix seq operations in smackfs ima: pass iint to ima_add_violation() ima: wrap event related data to the new ima_event_data structure integrity: add validity checks for 'path' parameter ...

crypto: asymmetric_keys/rsa - Use non-conflicting variable name

arm64:allmodconfig fails to build as follows. In file included from include/acpi/platform/aclinux.h:74:0, from include/acpi/platform/acenv.h:173, from include/acpi/acpi.h:56, from include/linux/acpi.h:37, from ./arch/arm64/include/asm/dma-mapping.h:21, from include/linux/dma-mapping.h:86, from include/linux/skbuff.h:34, from include/crypto/algapi.h:18, from crypto/asymmetric_keys/rsa.c:16: include/linux/ctype.h:15:12: error: expected ‘;’, ‘,’ or ‘)’ before numeric constant #define _X 0x40 /* hex digit */ ^ crypto/asymmetric_keys/rsa.c:123:47: note: in expansion of macro ‘_X’ static int RSA_I2OSP(MPI x, size_t xLen, u8 **_X) ^ crypto/asymmetric_keys/rsa.c: In function ‘RSA_verify_signature’: crypto/asymmetric_keys/rsa.c:256:2: error: implicit declaration of function ‘RSA_I2OSP’ The problem is caused by an unrelated include file change, resulting in the inclusion of ctype.h on arm64. This in turn causes the local variable _X to conflict with macro _X used in ctype.h.

crypto/asymmetric_keys: pkcs7_key_type needs module.h

2015-06-16T18:12:26Z

This driver builds off of the tristate CONFIG_PKCS7_TEST_KEY and calls module_init and module_exit. So it should explicitly include module.h to avoid compile breakage during header shuffles done in the future. Cc: Herbert Xu Cc: "David S.

KEYS: fix "ca_keys=" partial key matching

2015-05-21T17:58:59Z

The call to asymmetric_key_hex_to_key_id() from ca_keys_setup() silently fails with -ENOMEM. Instead of dynamically allocating memory from a __setup function, this patch defines a variable and calls __asymmetric_key_hex_to_key_id(), a new helper function, directly. This bug was introduced by 'commit 46963b774d44 ("KEYS: Overhaul key identification when searching for asymmetric keys")'. Changelog: - for clarification, rename hexlen to asciihexlen in asymmetric_key_hex_to_key_id() - add size argument to __asymmetric_key_hex_to_key_id() - David Howells - inline __asymmetric_key_hex_to_key_id() - David Howells - remove duplicate strlen() calls Acked-by: David Howells Signed-off-by: Mimi Zohar Cc: stable@vger.kernel.org # 3.18

KEYS: output last portion of fingerprint in /proc/keys

2014-10-06T16:33:27Z

Previous version of KEYS used to output last 4 bytes of fingerprint. Now it outputs 8 last bytes of raw subject, which does not make any visual meaning at all. This patch restores old behavior. Signed-off-by: Dmitry Kasatkin Signed-off-by: David Howells

KEYS: strip 'id:' from ca_keyid

2014-10-06T16:33:27Z

The 'id:' prefix must be stripped for asymmetric_key_hex_to_key_id() to be able to process ca_keyid. Signed-off-by: Dmitry Kasatkin Signed-off-by: David Howells

KEYS: use swapped SKID for performing partial matching

2014-10-06T15:56:08Z

Earlier KEYS code used pure subject key identifiers (fingerprint) for searching keys. Latest merged code removed that and broke compatibility with integrity subsytem signatures and original format of module signatures. This patch returns back partial matching on SKID.

KEYS: Restore partial ID matching functionality for asymmetric keys

2014-10-06T14:21:05Z

Bring back the functionality whereby an asymmetric key can be matched with a partial match on one of its IDs. Whilst we're at it, allow for the possibility of having an increased number of IDs. Reported-by: Dmitry Kasatkin Signed-off-by: Dmitry Kasatkin Signed-off-by: David Howells
