[Devel] [PATCH rh7] ploop: fix counting bio_qlen

The commit ec1eeb868 (May 22 2015) ported "separate queue for discard bio" patch from RHEL6-based kernel incorrectly. Original patch stated clearly that if we want to decrement bio_discard_qlen, bio_qlen must not change: @@ -500,7 +502,7 @@ ploop_bio_queue(struct ploop_device * pl

[Devel] [PATCH rh7] ve/device_cgroup: kill ACC_QUOTA permission

This is a leftover from PCS6. Currently this code does absolutely nothing, so let's remove it. Signed-off-by: Andrey Ryabinin --- include/linux/fs.h | 1 - security/device_cgroup.c | 13 ++--- 2 files changed, 2 insertions(+), 12 deletions(-) diff --git

[Devel] [PATCH rh7] ve/device_cgroup: allow to change device mount permission via cgroup

Currently, in order to allow a Container to mount device, we call an ioctl(get_vzctlfd(), VZCTL_SETDEVPERMS, ) with S_IXUSR bit set. In fact, this ioctl() is just a wrapper around dev cgroup interface, which is very odd. Instead, lets allow to change mount permission via dev cgroup interface.

[Devel] [PATCH rh7] security: device_cgroup -- Allow manage devices in @pseudosuper state

When restoring containers with several disks it's more convenient to mount device first and the setup permissions needed. So for this sake we allow to escape device permissions testing inside VE only if @pseudosuper state enabled. https://jira.sw.ru/browse/PSBM-48421 CC: Vladimir Davydov
