| 60 | .\" ////////////////////////////////////////////////////////////////////////// | |
| 61 | .P | |
| 62 | While the seccomp filter can be generated independent of the kernel, kernel | |
| 63 | support is required to load and enforce the seccomp filter generated by | |
| 64 | libseccomp. | |
| 65 | .P | |
| 66 | The libseccomp project site, with more information and the source code | |
| 67 | repository, can be found at https://github.com/seccomp/libseccomp. This tool, | |
| 68 | as well as the libseccomp library, is currently under development, please | |
| 69 | report any bugs at the project site or directly to the author. | |
