2018-02-07uuid: cleanup <uapi/linux/uuid.h>Alexey Dobriyan1-0/+1
Exported header doesn't use anything from <linux/string.h>, it is <linux/uuid.h> which uses memcmp().

2017-06-22ras: acpi / apei: generate trace event for unrecognized CPER sectionTyler Baicar1-1/+3
The UEFI spec includes non-standard section type support in the Common Platform Error Record. This is defined in section N.2.3 of UEFI version 2.5. Currently if the CPER section's type (UUID) does not match any section type that the kernel knows how to parse, a trace event is not generated. Generate a trace event which contains the raw error data for non-standard section type error records.

2017-06-05uuid: hoist uuid_is_null() helper from libnvdimmChristoph Hellwig1-0/+13
Hoist the libnvdimm helper as an inline helper to linux/uuid.h using an auxiliary const variable uuid_null in lib/uuid.c. [hch: also add the guid variant. Both do the same but I'd like to keep casts to a minimum] The common helper uses the new abstract type uuid_t * instead of u8 *.

2017-06-05uuid: rename uuid typesChristoph Hellwig1-23/+32
Our "little endian" UUID really is a Wintel GUID, so rename it and its helpers such (guid_t). The big endian UUID is the only true one, so give it the name uuid_t. The uuid_le and uuid_be names are retained for now, but will hopefully go away soon. The exception to that are the _cmp helpers that will be replaced by better primitives ASAP and thus don't get the new names. Also the _to_bin helpers are named to match the better named uuid_parse routine in userspace. Also remove the existing typedef in XFS that's now been superceeded by the generic type name.

2017-06-05uuid,afs: move struct uuid_v1 back into afsChristoph Hellwig1-24/+0
This essentially is a partial revert of commit ff548773 ("afs: Move UUID struct to linux/uuid.h") and moves struct uuid_v1 back into fs/afs as struct afs_uuid. It however keeps it as big endian structure so that we can use the normal uuid generation helpers when casting to/from struct afs_uuid. The V1 uuid intrepretation in struct form isn't really useful to the rest of the kernel, and not really compatible to it either, so move it back to AFS instead of polluting the global uuid.h.

2016-05-21lib/uuid.c: introduce a few more generic helpersAndy Shevchenko1-0/+13
There are new helpers in this patch: uuid_is_valid checks if a UUID is valid uuid_be_to_bin converts from string to binary (big endian) uuid_le_to_bin converts from string to binary (little endian) They will be used in future, i.e. in the following patches in the series. This also moves the indices arrays to lib/uuid.c to be shared accross modules.

2010-05-20Unified UUID/GUID definitionHuang Ying1-0/+70
There are many different UUID/GUID definitions in kernel, such as that in EFI, many file systems, some drivers, etc. Every kernel components need UUID/GUID has its own definition. This patch provides a unified definition for UUID/GUID. UUID is defined via typedef. This makes that UUID appears more like a preliminary type, and makes the data type explicit (comparing with implicit "u8 uuid[16]"). The binary representation of UUID/GUID can be little-endian (used by EFI, etc) or big-endian (defined by RFC4122), so both is defined.
