this kernel does not implement |
.br fanotify_init (). |
the fanotify api is available only if the kernel was configured with |
.br config_fanotify . |
.tp |
.b eperm |
the operation is not permitted because the caller lacks the |
.b cap_sys_admin |
capability. |

.br fanotify_init () |
was introduced in version 2.6.36 of the linux kernel and enabled in version |
2.6.37. |
.sh conforming to |
this system call is linux-specific. |

the following bug was present in linux kernels before version 3.18: |

the following bug was present in linux kernels before version 3.14: |
.ip * 3 |
.\" fixed by commit 48149e9d3a7e924010a0daab30a6197b7d7b6580 |
the |
.i event_f_flags |
argument is not checked for invalid flags. |
flags that are intended only for internal use, |
such as |
.br fmode_exec , |
can be set, and will consequently be set for the file descriptors |
returned when reading from the fanotify file descriptor. |

the |
.br mtrace () |
function installs hook functions for the memory-allocation functions |
.rb ( malloc (3), |
.br realloc (3) |
.br memalign (3), |
.br free (3)). |
these hook functions record tracing information about memory allocation |
and deallocation. |
the tracing information can be used to discover memory leaks and |
attempts to free nonallocated memory in a program. |
