Constants

All numeric constants used in the LCS interface. An independent implementer can derive all magic numbers from this page.

§11.1.1 Syscall numbers #

§11.1.2 Ioctl definitions #

Type byte: 'R' (0x52).

§11.1.2.1 Source registration ioctl (on /dev/pkm_registry fd) #

Ioctl number namespaces are per-fd-type. REG_SRC_REGISTER (number 0 on /dev/pkm_registry fds) does not conflict with key fd ioctls (number 0 on key fds) because the kernel dispatches ioctls based on the fd's file_operations, not globally.

§11.1.2.2 Key fd ioctls #

§11.1.2.3 Transaction fd ioctls #

§11.1.2.4 Transaction states #

§11.1.3 Syscall flags #

§11.1.3.1 reg_open_key flags #

§11.1.3.2 reg_create_key flags #

§11.1.3.3 Disposition values #

§11.1.4 Access rights #

§11.1.4.1 Specific rights (bits 0--15) #

§11.1.4.2 Standard rights (bits 16--23) #

§11.1.4.3 System rights #

§11.1.4.4 Raw generic access bits #

§11.1.4.5 Generic mappings #

KEY_READ, KEY_WRITE, and KEY_ALL_ACCESS are concrete registry convenience masks. The raw generic access bits above are accepted in desired_access and ACE masks before mapping. GENERIC_EXECUTE maps to 0 for registry keys.

§11.1.4.6 Access mask validation constants #

SYNCHRONIZE (0x00100000) is not a registry key right in v0.21.

§11.1.5 Value types #

REG_IOC_SET_VALUE rejects unknown value type codes with EINVAL. REG_TOMBSTONE is accepted only for explicit per-value tombstone writes and requires zero-length data.

§11.1.6 Watch event types #

§11.1.7 Watch filter bits #

§11.1.8 RSI op codes #

§11.1.9 RSI error codes #

§11.1.10 RSI transaction modes #

§11.1.11 RSI registration flags #

§11.1.12 Backup record types #

§11.1.13 Backup magic #
