Pull keys updates from James Morris: "Provide five new operations in the key_type struct that can be used to provide access to asymmetric key operations. These will be implemented for the asymmetric key type in a later patch and may refer to a key retained in RAM by the kernel or a key retained in crypto hardware. int (*asym_query)(const struct kernel_pkey_params *params, struct kernel_pkey_query *info); int (*asym_eds_op)(struct kernel_pkey_params *params, const void *in, void *out); int (*asym_verify_signature)(struct kernel_pkey_params *params, const void *in, const void *in2); Since encrypt, decrypt and sign are identical in their interfaces, they're rolled together in the asym_eds_op() operation and there's an operation ID in the params argument to distinguish them. Verify is different in that we supply the data and the signature instead and get an error value (or 0) as the only result on the expectation that this may well be how a hardware crypto device may work" * 'next-keys2' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security: (22 commits) KEYS: asym_tpm: Add support for the sign operation [ver #2] KEYS: asym_tpm: Implement tpm_sign [ver #2] KEYS: asym_tpm: Implement signature verification [ver #2] KEYS: asym_tpm: Implement the decrypt operation [ver #2] KEYS: asym_tpm: Implement tpm_unbind [ver #2] KEYS: asym_tpm: Add loadkey2 and flushspecific [ver #2] KEYS: Move trusted.h to include/keys [ver #2] KEYS: trusted: Expose common functionality [ver #2] KEYS: asym_tpm: Implement encryption operation [ver #2] KEYS: asym_tpm: Implement pkey_query [ver #2] KEYS: Add parser for TPM-based keys [ver #2] KEYS: asym_tpm: extract key size & public key [ver #2] KEYS: asym_tpm: add skeleton for asym_tpm [ver #2] crypto: rsa-pkcs1pad: Allow hash to be optional [ver #2] KEYS: Implement PKCS#8 RSA Private Key parser [ver #2] KEYS: Implement encrypt, decrypt and sign for software asymmetric key [ver #2] KEYS: Allow the public_key struct to hold a private key [ver #2] KEYS: Provide software public key query function [ver #2] KEYS: Make the X.509 and PKCS7 parsers supply the sig encoding type [ver #2] KEYS: Provide missing asymmetric key subops for new key type ops [ver #2] ...

Pull more RISC-V updates from Palmer Dabbelt: "This contains the follow-on patches I'd like to target for the 4.20 merge window. I'm being somewhat conservative here, as while there are a few patches on the mailing list that were posted early in the merge window I'd like to let those bake for another round -- this was a fairly big release as far as RISC-V is concerened, and we need to walk before we can run. As far as the patches that made it go: - A patch to ignore offline CPUs when calculating AT_HWCAP. This should fix GDB on the HiFive unleashed, which has an embedded core for hart 0 which is exposed to Linux as an offline CPU. - A move of EM_RISCV to elf-em.h, which is where it should have been to begin with. - I've also removed the 64-bit divide routines. I know I'm not really playing by my own rules here because I posted the patches this morning, but since they shouldn't be in the kernel I think it's better to err on the side of going too fast here. I don't anticipate any more patch sets for the merge window" * tag 'riscv-for-linus-4.20-mw2' of git://git.kernel.org/pub/scm/linux/kernel/git/palmer/riscv-linux: Move EM_RISCV into elf-em.h RISC-V: properly determine hardware caps Revert "lib: Add umoddi3 and udivmoddi4 of GCC library routines" Revert "RISC-V: Select GENERIC_LIB_UMODDI3 on RV32"

Pull new experimental media request API from Mauro Carvalho Chehab: "A new media request API This API is needed to support device drivers that can dynamically change their parameters for each new frame. The latest versions of Google camera and codec HAL depends on such feature. At this stage, it supports only stateless codecs. It has been discussed for a long time (at least over the last 3-4 years), and we finally reached to something that seem to work. This series contain both the API and core changes required to support it and a new m2m decoder driver (cedrus). As the current API is still experimental, the only real driver using it (cedrus) was added at staging[1]. We intend to keep it there for a while, in order to test the API. Only when we're sure that this API works for other cases (like encoders), we'll move this driver out of staging and set the API into a stone. [1] We added support for the vivid virtual driver (used only for testing) to it too, as it makes easier to test the API for the ones that don't have the cedrus hardware" * tag 'media/v4.20-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (53 commits) media: dt-bindings: Document the Rockchip VPU bindings media: platform: Add Cedrus VPU decoder driver media: dt-bindings: media: Document bindings for the Cedrus VPU driver media: v4l: Add definition for the Sunxi tiled NV12 format media: v4l: Add definitions for MPEG-2 slice format and metadata media: videobuf2-core: Rework and rename helper for request buffer count media: v4l2-ctrls.c: initialize an error return code with zero media: v4l2-compat-ioctl32.c: add missing documentation for a field media: media-request: update documentation media: media-request: EPERM -> EACCES/EBUSY media: v4l2-ctrls: improve media_request_(un)lock_for_update media: v4l2-ctrls: use media_request_(un)lock_for_access media: media-request: add media_request_(un)lock_for_access media: vb2: set reqbufs/create_bufs capabilities media: videodev2.h: add new capabilities for buffer types media: buffer.rst: only set V4L2_BUF_FLAG_REQUEST_FD for QBUF media: v4l2-ctrls: return -EACCES if request wasn't completed media: media-request: return -EINVAL for invalid request_fds media: vivid: add request support media: vivid: add mc ...

perf tools: Don't clone maps from parent when synthesizing forks

2018-10-31T13:18:01+00:00

When synthesizing FORK events, we are trying to create thread objects for the already running tasks on the machine. Normally, for a kernel FORK event, we want to clone the parent's maps because that is what the kernel just did. But when synthesizing, this should not be done. If we do, we end up with overlapping maps as we process the sythesized MMAP2 events that get delivered shortly thereafter. Use the FORK event misc flags in an internal way to signal this situation, so we can elide the map clone when appropriate. Signed-off-by: David S.
