--- Comment #6 from [email protected] --- A commit references this bug: Author: pjd Date: Sat Aug 8 09:51:41 UTC 2015 New revision: 286444 URL: https://svnweb.freebsd.org/changeset/base/286444 Log: Enable BIO_DELETE passthru in GELI, so TRIM/UNMAP can work as expected when GELI is used on a SSD or inside virtual machine, so that guest can tell host that it is no longer using some of the storage. Enabling BIO_DELETE passthru comes with a small security consequence - an attacker can tell how much space is being really used on encrypted device and has less data no analyse then. This is why the -T option can be given to the init subcommand to turn off this behaviour and -t/T options for the configure subcommand can be used to adjust this setting later. PR: 198863 Submitted by: Matthew D. Fuller fullermd at over-yonder dot net This commit also includes a fix from Fabian Keil freebsd-listen at fabiankeil.de for 'configure' on onetime providers which is not strictly related, but is entangled in the same code, so would cause conflicts if separated out.
