From db3b3c7281ca82e2647e072a1f97db111313dd73 Mon Sep 17 00:00:00 2001 From: Greg Kurz Date: Mon, 8 Jan 2018 11:18:23 +0100 Subject: 9pfs: deprecate handle backend This backend raise some concerns: - doesn't support symlinks - fails +100 tests in the PJD POSIX file system test suite [1] - requires the QEMU process to run with the CAP_DAC_READ_SEARCH capability, which isn't recommended for security reasons This backend should not be used and wil be removed. The 'local' backend is the recommended alternative. [1] https://www.tuxera.com/community/posix-test-suite/ Signed-off-by: Greg Kurz Reviewed-by: Daniel P.
