sched: Misc preps for cgroup unified hierarchy interface
|
|
||||||
|
|
||||||
Make the following changes in preparation for the cpu controller
|
|
||||||
interface implementation for the unified hierarchy. This patch
|
|
||||||
doesn't cause any functional differences.
|
|
||||||
|
|
||||||
* s/cpu_stats_show()/cpu_cfs_stats_show()/
|
|
||||||
|
|
||||||
* s/cpu_files/cpu_legacy_files/
|
|
||||||
|
|
||||||
* Separate out cpuacct_stats_read() from cpuacct_stats_show(). While
|
|
||||||
at it, remove pointless cpuacct_stat_desc[] array.

sched: Implement interface for cgroup unified hierarchy
|
|
||||||
|
|
||||||
While the cpu controller doesn't have any functional problems, there
|
|
||||||
are a couple interface issues which can be addressed in the v2
|
|
||||||
interface.
|
|
||||||
|
|
||||||
* cpuacct being a separate controller. This separation is artificial
|
|
||||||
and rather pointless as demonstrated by most use cases co-mounting
|
|
||||||
the two controllers. It also forces certain information to be
|
|
||||||
accounted twice.
|
|
||||||
|
|
||||||
* Use of different time units. Writable control knobs use
|
|
||||||
microseconds, some stat fields use nanoseconds while other cpuacct
|
|
||||||
stat fields use centiseconds.
|
|
||||||
|
|
||||||
* Control knobs which can't be used in the root cgroup still show up
|
|
||||||
in the root.
|
|
||||||
|
|
||||||
* Control knob names and semantics aren't consistent with other
|
|
||||||
controllers.
|
|
||||||
|
|
||||||
This patchset implements cpu controller's interface on the unified
|
|
||||||
hierarchy which adheres to the controller file conventions described
|
|
||||||
in Documentation/cgroups/unified-hierarchy.txt. Overall, the
|
|
||||||
following changes are made.
|
|
||||||
|
|
||||||
* cpuacct is implictly enabled and disabled by cpu and its information
|
|
||||||
is reported through "cpu.stat" which now uses microseconds for all
|
|
||||||
time durations. All time duration fields now have "_usec" appended
|
|
||||||
to them for clarity. While this doesn't solve the double accounting
|
|
||||||
immediately, once majority of users switch to v2, cpu can directly
|
|
||||||
account and report the relevant stats and cpuacct can be disabled on
|
|
||||||
the unified hierarchy.
|
|
||||||
|
|
||||||
Note that cpuacct.usage_percpu is currently not included in
|
|
||||||
"cpu.stat". If this information is actually called for, it can be
|
|
||||||
added later.
|
|
||||||
|
|
||||||
* "cpu.shares" is replaced with "cpu.weight" and operates on the
|
|
||||||
standard scale defined by CGROUP_WEIGHT_MIN/DFL/MAX (1, 100, 10000).
|
|
||||||
The weight is scaled to scheduler weight so that 100 maps to 1024
|
|
||||||
and the ratio relationship is preserved - if weight is W and its
|
|
||||||
scaled value is S, W / 100 == S / 1024. While the mapped range is a
|
|
||||||
bit smaller than the orignal scheduler weight range, the dead zones
|
|
||||||
on both sides are relatively small and covers wider range than the
|
|
||||||
nice value mappings. This file doesn't make sense in the root
|
|
||||||
cgroup and isn't create on root.
|
|
||||||
|
|
||||||
* "cpu.cfs_quota_us" and "cpu.cfs_period_us" are replaced by "cpu.max"
|
|
||||||
which contains both quota and period.
|
|
||||||
|
|
||||||
* "cpu.rt_runtime_us" and "cpu.rt_period_us" are replaced by
|
|
||||||
"cpu.rt.max" which contains both runtime and period.
|
|
||||||
|
|
||||||
v2: cpu_stats_show() was incorrectly using CONFIG_FAIR_GROUP_SCHED for
|
|
||||||
CFS bandwidth stats and also using raw division for u64. Use
|
|
||||||
CONFIG_CFS_BANDWITH and do_div() instead.
|
|
||||||
|
|
||||||
The semantics of "cpu.rt.max" is not fully decided yet. Dropped
|
|
||||||
for now.

v3.14.31:crypto/crc32c.c is missing the MODULE_ALIAS_CRYPTO("crc32c").
|

That's probably because crypto/crc32c.c was renamed to

crypto/crc32c_generic.c in commit

06e5a1f29819759392239669beb2cad27059c8ec and therefore fell through

So the affected kernels (all that backported the "crypto-" prefix

Subject [PATCH] crypto: rsa - fix a potential race condition in build
|
|
||||||
Date Fri, 2 Dec 2016 15:41:04 -0800
|
|
||||||
|
|
||||||
|
|
||||||
When building kernel with RSA enabled with multithreaded, the below
|
|
||||||
compile failure might be caught:
|
|
||||||
|
|
||||||
| /buildarea/kernel-source/crypto/rsa_helper.c:18:28: fatal error: rsapubkey-asn1.h: No such file or directory
|
|
||||||
| #include "rsapubkey-asn1.h"
|
|
||||||
| ^
|
|
||||||
| compilation terminated.
|
|
||||||
| CC crypto/rsa-pkcs1pad.o
|
|
||||||
| CC crypto/algboss.o
|
|
||||||
| CC crypto/testmgr.o
|
|
||||||
| make[3]: *** [/buildarea/kernel-source/scripts/Makefile.build:289: crypto/rsa_helper.o] Error 1
|
|
||||||
| make[3]: *** Waiting for unfinished jobs....
|
|
||||||
| make[2]: *** [/buildarea/kernel-source/Makefile:969: crypto] Error 2
|
|
||||||
| make[1]: *** [Makefile:150: sub-make] Error 2
|
|
||||||
| make: *** [Makefile:24: __sub-make] Error 2
|
|
||||||
|
|
||||||
The header file is not generated before rsa_helper is compiled, so
|
|
||||||
adding dependency to avoid such issue.

Subject: [PATCH] UBUNTU: SAUCE: Overlayfs: allow unprivileged mounts
|
|
||||||
|
|
||||||
Unprivileged mounting, here, refers to root in a non-initial user
|
|
||||||
namespace performing the mount. In particular, it requires
|
|
||||||
CAP_SYS_ADMIN toward the task's mounts namespace, alleviating
|
|
||||||
the concerns of manipulating mount environment for setuid-root
|
|
||||||
binaries on the host.
|
|
||||||
|
|
||||||
We refuse unprivileged mounting of most filesystem types because
|
|
||||||
we do not trust the in-kernel superblock parsers to correctly
|
|
||||||
handle malicious input.
|
|
||||||
|
|
||||||
However, overlayfs does not parse any user-provided data other
|
|
||||||
than the pathnames passed in. Therefore unprivileged mounting
|
|
||||||
of overlayfs should be safe.
|
|
||||||
|
|
||||||
Allowing unprivileged mounting of overlayfs filesystems would
|
|
||||||
allow Ubuntu Trusty users to create overlayfs-based container
|
|
||||||
snapshots, which would be a huge usability improvement.
|
|
||||||
|
|
||||||
This patch enables unprivileged mounting of overlayfs.
|
|
||||||
|
|
||||||
I tested a few simple combinations, and found that, when
|
|
||||||
doing (the equivalent of)
|
|
||||||
|
|
||||||
mount -t overlayfs -oupperdir=u,lowerdir=l l t
|
|
||||||
|
|
||||||
(u for upper, l for lower, t for target),
|
|
||||||
|
|
||||||
1. overlayfs mount is always allowed, regardless of ownership
|
|
||||||
of u, l, or t. However
|
|
||||||
|
|
||||||
2. Creation of new files is allowed so long as u is owned by
|
|
||||||
T. Otherwise, regardless of ownerships of l and t it is
|
|
||||||
denied. (This is expected; t was the mountpoint and
|
|
||||||
'disapears', so its ownership is irrelevant)
|
|
||||||
|
|
||||||
3. modification of a file 'hithere' which is in l but not yet
|
|
||||||
in u, and which is not owned by T, is not allowed, even if
|
|
||||||
writes to u are allowed. This may be a bug in overlayfs,
|
|
||||||
but it is safe behavior. It also will not cause a problem
|
|
||||||
for lxc since lxc will ensure that files are mapped into T's
|
|
||||||
namespace.
