- Move the enabling of timeofday and alarm one level deeper to be sure it is whitelisted everytime. Also should possibly fix bnc#872215. - Updated patch: * vsftpd-enable-gettimeofday-sec.patch - Remove forking from service type as it hangs in endless loop. - Fix warning about dangling symlink on rcvsftpd from rpmlint and remove also clean section while at it. - Add patch to allow gettimeofday and alarm calls with seccomp enabled. bnc#870122 - Added patch: * vsftpd-enable-gettimeofday-sec.patch - Specify that the service type is forking - changed license to SUSE-GPL-2.0-with-openssl-exception * suggested by legal team - add allow_root_squashed_chroot option to enable chroot on nsf mounted with squash_root option (fate#311051) * vsftpd-root-squashed-chroot.patch OBS-URL: https://build.opensuse.org/request/show/229627 OBS-URL: https://build.opensuse.org/package/show/network/vsftpd?expand=0&rev=59
