https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D206654 Bug ID: 206654 Summary: sysutils/qjail speed up jail creation and other fixes Product: Ports & Packages Version: Latest Hardware: Any OS: Any Status: New Severity: Affects Many People Priority: --- Component: Individual Port(s) Assignee: freebsd-ports-bugs@FreeBSD.org Reporter: smh@FreeBSD.org CC: qjail1@a1poweruser.com Flags: maintainer-feedback?(qjail1@a1poweruser.com) Created attachment 166162 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D166162&action= =3Dedit Enhancements for qjail I've been using qjail to create many jails (2k per machine) on some load te= st hosts, during this we hit a few issues which we've fixed so wanted to pass = on the fixes. The fixes where: * Significantly improve performance of IP verification. This check gets exponentially slower the more jails are added due to the lo= ad of every previous jail config to validate it. We've changed this to a simple grep which achieves the same thing in a fraction of the time. * Refactor IP check to a single method. With the above changes it was trivial to make a single method replace the existing two. * Increase the jail limit from 100 =3D> 254 (max per subnet). There didn't seem to be any reason for this limit so increased it such that= an entire subject of jails can be created. * Fix output message typo. * Ignore missing definitions in some situations. When running parallel qjail creates we we're seeing random failures due to temporary definition files, which then disappeared. Deal with this by allow= ing read-definition to fail. The patch is attached, hope its helpful. --=20 You are receiving this mail because: You are the assignee for the bug.=
