Name
access - check real user's permissions for a fileSynopsis
Description
access() checks whether the calling process can access the file pathname. Ifpathname is a symbolic link, it is dereferenced.
The mode specifies the accessibility check(s) to be performed, and is either the value F_OK, or a mask consisting of the bitwise OR of one ormore of R_OK, W_OK, and X_OK. F_OK tests for the existence of the file. R_OK, W_OK, and X_OK test whether thefile exists and grants read, write, and execute permissions, respectively.
The check is done using the calling process's real UID and GID, rather than the effective IDs as is done when actually attempting an operation (e.g.,open(2)) on the file. This allows set-user-ID programs to easily determine the invoking user's authority.
If the calling process is privileged (i.e., its real UID is zero), then an X_OK check is successful for a regular file if execute permission isenabled for any of the file owner, group, or other.
Return Value
On success (all requested permissions granted), zero is returned. On error (at least one bitinmode asked for a permission that is denied, or some other error occurred), -1 is returned, and errno is set appropriately.
Errors
access() shall fail if:- EFAULT
- pathname points outside your accessible address space.
- EINVAL
- mode was incorrectly specified.
- EIO
- An I/O error occurred.
- ENOMEM
- Insufficient kernel memory was available.
- ETXTBSY
- Write access was requested to an executable which is being executed.
Conforming to
SVr4, 4.3BSD, POSIX.1-2001.Notes
Warning: Using access() to check if a user is authorized to, for example, open a file before actually doing so using open(2)creates a security hole, because the user might exploit the short time interval between checking and opening the file to manipulate it. For this reason, theuse of this system call should be avoided. (In the example just described, a safer alternative would be to temporarily switch the process's effective userID to the real ID and then call open(2).)
access() always dereferences symbolic links. If you need to check the permissions on a symbolic link, use faccessat(2) with the flagAT_SYMLINK_NOFOLLOW.
access() returns an error if any of the access types in mode is denied, even if some of the other access types in mode are permitted.
If the calling process has appropriate privileges (i.e., is superuser), POSIX.1-2001 permits an implementation to indicate success for an X_OK checkeven if none of the execute file permission bits are set. Linux does not do this.
A file is only accessible if the permissions on each of the directories in the path prefix of pathname grant search (i.e., execute) access. If anydirectory is inaccessible, then the access() call will fail, regardless of the permissions on the file itself.
Only access bits are checked, not the file type or contents. Therefore, if a directory is found to be writable, it probably means that files can be createdin the directory, and not that the directory can be written as a file. Similarly, a DOS file may be found to be 'executable,' but the execve(2)call will still fail.
access() may not work correctly on NFS file systems with UID mapping enabled, because UID mapping is done on the server and hidden from the client,which checks permissions. Similar problems can occur to FUSE mounts.
Bugs
In kernel 2.4 (and earlier) there is some strangeness in the handling of X_OK tests forsuperuser. If all categories of execute permission are disabled for a nondirectory file, then the only access() test that returns -1 is when modeis specified as just X_OK; if R_OK or W_OK is also specified in mode, then access() returns 0 for such files. Early 2.6kernels (up to and including 2.6.3) also behaved in the same way as kernel 2.4.In kernels before 2.6.20, access() ignored the effect of the MS_NOEXEC flag if it was used to mount(2) the underlying filesystem. Since kernel 2.6.20, access() honors this flag.
