For patches, it is probably best to # add the new privilege at the end; for ordinary releases privileges # should be ordered alphabetically. # privilege PRIV_CONTRACT_EVENT Allows a process to request critical events without limitation. Allows a process to request reliable delivery of all events on any event queue. privilege PRIV_CONTRACT_OBSERVER Allows a process to observe contract events generated by contracts created and owned by users other than the process's effective user ID. Allows a process to open contract event endpoints belonging to contracts created and owned by users other than the process's effective user ID. privilege PRIV_CPC_CPU Allow a process to access per-CPU hardware performance counters. privilege PRIV_DTRACE_KERNEL Allows DTrace kernel-level tracing. privilege PRIV_DTRACE_PROC Allows DTrace process-level tracing. Allows process-level tracing probes to be placed and enabled in processes to which the user has permissions. privilege PRIV_DTRACE_USER Allows DTrace user-level tracing. Allows use of the syscall and profile DTrace providers to examine processes to which the user has permissions. privilege PRIV_FILE_CHOWN Allows a process to change a file's owner user ID. Allows a process to change a file's group ID to one other than the process' effective group ID or one of the process' supplemental group IDs. privilege PRIV_FILE_CHOWN_SELF Allows a process to give away its files; a process with this privilege will run as if {_POSIX_CHOWN_RESTRICTED} is not in effect. privilege PRIV_FILE_DAC_EXECUTE Allows a process to execute an executable file whose permission bits or ACL do not allow the process execute permission. privilege PRIV_FILE_DAC_READ Allows a process to read a file or directory whose permission bits or ACL do not allow the process read permission. privilege PRIV_FILE_DAC_SEARCH Allows a process to search a directory whose permission bits or ACL do not allow the process search permission. privilege PRIV_FILE_DAC_WRITE Allows a process to write a file or directory whose permission bits or ACL do not allow the process write permission. In order to write files owned by uid 0 in the absence of an effective uid of 0 ALL privileges are required. privilege PRIV_FILE_DOWNGRADE_SL Allows a process to set the sensitivity label of a file or directory to a sensitivity label that does not dominate the existing sensitivity label. This privilege is interpreted only if the system is configured with Trusted Extensions. basic privilege PRIV_FILE_LINK_ANY Allows a process to create hardlinks to files owned by a uid different from the process' effective uid. privilege PRIV_FILE_OWNER Allows a process which is not the owner of a file or directory to perform the following operations that are normally permitted only for the file owner: modify that file's access and modification times; remove or rename a file or directory whose parent directory has the ``save text image after execution'' (sticky) bit set; mount a ``namefs'' upon a file; modify permission bits or ACL except for the set-uid and set-gid bits. privilege PRIV_FILE_SETID Allows a process to change the ownership of a file or write to a file without the set-user-ID and set-group-ID bits being cleared. Allows a process to set the set-group-ID bit on a file or directory whose group is not the process' effective group or one of the process' supplemental groups. Allows a process to set the set-user-ID bit on a file with different ownership in the presence of PRIV_FILE_OWNER. Additional restrictions apply when creating or modifying a set-uid 0 file. privilege PRIV_FILE_UPGRADE_SL Allows a process to set the sensitivity label of a file or directory to a sensitivity label that dominates the existing sensitivity label. This privilege is interpreted only if the system is configured with Trusted Extensions. privilege PRIV_GRAPHICS_ACCESS Allows a process to make privileged ioctls to graphics devices. Typically only xserver process needs to have this privilege. A process with this privilege is also allowed to perform privileged graphics device mappings. privilege PRIV_GRAPHICS_MAP Allows a process to perform privileged mappings through a graphics device. privilege PRIV_IPC_DAC_READ Allows a process to read a System V IPC Message Queue, Semaphore Set, or Shared Memory Segment whose permission bits do not allow the process read permission. Allows a process to read remote shared memory whose permission bits do not allow the process read permission. privilege PRIV_IPC_DAC_WRITE Allows a process to write a System V IPC Message Queue, Semaphore Set, or Shared Memory Segment whose permission bits do not allow the process write permission.

This privilege is interpreted only if the system is configured with Trusted Extensions. privilege PRIV_NET_ICMPACCESS Allows a process to send and receive ICMP packets. privilege PRIV_NET_MAC_AWARE Allows a process to set NET_MAC_AWARE process flag by using setpflags(2). This privilege also allows a process to set SO_MAC_EXEMPT socket option by using setsockopt(3SOCKET). The NET_MAC_AWARE process flag and the SO_MAC_EXEMPT socket option both allow a local process to communicate with an unlabeled peer if the local process' label dominates the peer's default label, or if the local process runs in the global zone. This privilege is interpreted only if the system is configured with Trusted Extensions. privilege PRIV_NET_PRIVADDR Allows a process to bind to a privileged port number. The privilege port numbers are 1-1023 (the traditional UNIX privileged ports) as well as those ports marked as "udp/tcp_extra_priv_ports" with the exception of the ports reserved for use by NFS. privilege PRIV_NET_RAWACCESS Allows a process to have direct access to the network layer. unsafe privilege PRIV_PROC_AUDIT Allows a process to generate audit records. Allows a process to get its own audit pre-selection information. privilege PRIV_PROC_CHROOT Allows a process to change its root directory. privilege PRIV_PROC_CLOCK_HIGHRES Allows a process to use high resolution timers. basic privilege PRIV_PROC_EXEC Allows a process to call execve(). basic privilege PRIV_PROC_FORK Allows a process to call fork1()/forkall()/vfork() basic privilege PRIV_PROC_INFO Allows a process to examine the status of processes other than those it can send signals to. Processes which cannot be examined cannot be seen in /proc and appear not to exist. privilege PRIV_PROC_LOCK_MEMORY Allows a process to lock pages in physical memory. privilege PRIV_PROC_OWNER Allows a process to send signals to other processes, inspect and modify process state to other processes regardless of ownership. When modifying another process, additional restrictions apply: the effective privilege set of the attaching process must be a superset of the target process' effective, permitted and inheritable sets; the limit set must be a superset of the target's limit set; if the target process has any uid set to 0 all privilege must be asserted unless the effective uid is 0. Allows a process to bind arbitrary processes to CPUs. privilege PRIV_PROC_PRIOCNTL Allows a process to elevate its priority above its current level. Allows a process to change its scheduling class to any scheduling class, including the RT class. basic privilege PRIV_PROC_SESSION Allows a process to send signals or trace processes outside its session. unsafe privilege PRIV_PROC_SETID Allows a process to set its uids at will. Assuming uid 0 requires all privileges to be asserted. privilege PRIV_PROC_TASKID Allows a process to assign a new task ID to the calling process. privilege PRIV_PROC_ZONE Allows a process to trace or send signals to processes in other zones. privilege PRIV_SYS_ACCT Allows a process to enable and disable and manage accounting through acct(2), getacct(2), putacct(2) and wracct(2). privilege PRIV_SYS_ADMIN Allows a process to perform system administration tasks such as setting node and domain name and specifying nscd and coreadm settings. privilege PRIV_SYS_AUDIT Allows a process to start the (kernel) audit daemon. Allows a process to view and set audit state (audit user ID, audit terminal ID, audit sessions ID, audit pre-selection mask). Allows a process to turn off and on auditing. Allows a process to configure the audit parameters (cache and queue sizes, event to class mappings, policy options). privilege PRIV_SYS_CONFIG Allows a process to perform various system configuration tasks. Allows a process to add and remove swap devices; when adding a swap device, a process must also have sufficient privileges to read from and write to the swap device. privilege PRIV_SYS_DEVICES Allows a process to successfully call a kernel module that calls the kernel drv_priv(9F) function to check for allowed access. Allows a process to open the real console device directly. Allows a process to open devices that have been exclusively opened. privilege PRIV_SYS_IPC_CONFIG Allows a process to increase the size of a System V IPC Message Queue buffer. privilege PRIV_SYS_LINKDIR Allows a process to unlink and link directories. privilege PRIV_SYS_MOUNT Allows filesystem specific administrative procedures, such as filesystem configuration ioctls, quota calls and creation/deletion of snapshots. Allows a process to mount and unmount filesystems which would otherwise be restricted (i.e., most filesystems except namefs). A process performing a mount operation needs to have appropriate access to the device being mounted (read-write for "rw" mounts, read for "ro" mounts). A process performing any of the aforementioned filesystem operations needs to have read/write/owner access to the mount point. Only regular files and directories can serve as mount points for processes which do not have all zone privileges asserted. Unless a process has all zone privileges, the mount(2) system call will force the "nosuid" and "restrict" options, the latter only for autofs mountpoints. Regardless of privileges, a process running in a non-global zone may only control mounts performed from within said zone. Outside the global zone, the "nodevices" option is always forced. privilege PRIV_SYS_NET_CONFIG Allows a process to configure a system's network interfaces and routes. Allows a process to configure network parameters using ndd. Allows a process access to otherwise restricted information using ndd. Allows a process to push the rpcmod STREAMs module.

Allows a process to change the operational status of CPUs in the system using p_online(2). Allows a process to configure resource pools and to bind processes to pools unsafe privilege PRIV_SYS_RESOURCE Allows a process to modify the resource limits specified by setrlimit(2) and setrctl(2) without restriction. Allows a process to exceed the per-user maximum number of processes. Allows a process to extend or create files on a filesystem that has less than minfree space in reserve. privilege PRIV_SYS_SUSER_COMPAT Allows a process to successfully call a third party loadable module that calls the kernel suser() function to check for allowed access. This privilege exists only for third party loadable module compatibility and is not used by Solaris proper. privilege PRIV_SYS_TIME Allows a process to manipulate system time using any of the appropriate system calls: stime, adjtime, ntp_adjtime and the IA specific RTC calls. privilege PRIV_SYS_TRANS_LABEL Allows a process to translate labels that are not dominated by the process' sensitivity label to and from an external string form. This privilege is interpreted only if the system is configured with Trusted Extensions. privilege PRIV_WIN_COLORMAP Allows a process to override colormap restrictions. Allows a process to install or remove colormaps. Allows a process to retrieve colormap cell entries allocated by other processes.

Allows a process to get and set keyboard and pointer controls. Allows a process to modify pointer button and key mappings. This privilege is interpreted only if the system is configured with Trusted Extensions. privilege PRIV_WIN_DGA Allows a process to use the direct graphics access (DGA) X protocol extensions. Direct process access to the frame buffer is still required. Thus the process must have MAC and DAC privileges that allow access to the frame buffer, or the frame buffer must be allocated to the process. This privilege is interpreted only if the system is configured with Trusted Extensions. privilege PRIV_WIN_DOWNGRADE_SL Allows a process to set the sensitivity label of a window resource to a sensitivity label that does not dominate the existing sensitivity label. This privilege is interpreted only if the system is configured with Trusted Extensions. privilege PRIV_WIN_FONTPATH Allows a process to set a font path.
