LU-8854 llapi: remove lustre specific strlcpy & strlcat functions

In the days when lustre supported many more platforms some of those
platforms natively support strl[cpy|cat] but Linux has always lack
these functions. So lustre ended up providing its own versions of
these functions to fill in this functionality. Today Lustre only
supports the Linux platforms which has a version of libc that will
most likely never support strl[cat|cpy]. Since this is the case we
can remove the AC_CHECK_FUNCS since they only test against libc.
We could support detecting strl[cpy|cat] in another library but
many libraries provide their own version so the chances of collision
are high. The best solution is remove strlcpy and strlcat by
replacing those functions with string functions that are always
provided by the standard c library.

LU-6867 test: detect active facet based on current state

Lustre failover tests can not be ran test-by-test
on the setup with ${facet}_HOST != ${facet}failover_HOST
because of t-f does not restore facet state.
t-f keeps this info in "${facet}active" files, which are created
when facet_failover() is executed first time in the test session.
Before facet_failover() executed these files are empty and
active facet is ${facet} by default.
In case when tests are executed test-by-test the active facet is
${facet}failover after 1st test completed, and 2nd test is started
having ${facet}failover active without this info stored in
${facet}active files.

Patch contains the following changes:
- add the active facet detection based on current lustre state;
- fix sanity-hsm defect: exist with error if agt${n}1_HOST is empty.

LU-10561 flr: remove "--parent" option from lfs mirror command

"--parent" option for "lfs mirror create/extend" command was
originally designed to use default stripe options inherited
from parent directory. However, if parent directory has
composite layout, there will be inconsistency to choose the
stripe options from which component to inherit. And if there
is any other option specified, it's also inconsistent to
inherit the layout of parent directory.

So, this patch removes "--parent" option to eliminate ambiguity.
For "--pool|-p" option, this patch supports specifying "none" to
clear the pool name and inherit from parent directory.

Unspecified stripe count, stripe size and OST pool name will
inherit from previous component. If there is no previous component,
then unspecified stripe count and stripe size attributes will
inherit from filesystem-wide default values. Unspecified or
cleared OST pool name will inherit from parent directory.

In order to match the enhanced ea_inode functionality being landed
to the upstream ext4 kernel tree, ext4-large-eas.patch is modified
to start properly initializing some of the fields we don't

In particular, the new EA inode refcount is initialized to 1, and
hash field is computed based on the xattr value as it is in the
upstream kernel patch.

However, since ext4_xattr_inode_get_hash() has not been added to
ldiskfs code so that this hash value is not used anywhere, if the
new checksum driver (sbi->s_chksum_driver) is not available, hash
value will be 0 in the current implementation, until we find a way
to calculate it based on the xattr value propely.

It reduces the ChangeLog load significantly, without significantly

To achieve this, add a list to struct mdd_object, containing uid/gid

LU-10438 flr: layout truncate compatibility

In PFL design, client issues [0, size) intent to MDS to instantiate
objects in this extent. While in FLR design, the intent serves two
purposes: 1) make objects across [size, EOF) on other mirrors stale,
and 2) instantiate objects in the chosen write mirror. And original
FLR chose to use [size, EOF) as the extent of truncate write intent
request.

This patch reverts the choice, and still uses [0, size) as the
truncate write intent extent.

LU-9771 util: rename LCM_FL_NOT_FLR to LCM_FL_NONE

Having "lfs getstripe" print out "lcm_flags: not_flr" is not very
useful, as the composite files may not relate to FLR (e.g. PFL).
Rename "LCM_FL_NOT_FLR" to "LCM_FL_NONE" so it is more clear there

LU-5152 quota: enforce block quota for chgrp

When an unprivileged user calls chgrp to change the group
of one of his files, the block quota limit of that new group
should be checked to ensure it not exceeds the limit.

The side effect of this patch could be,
1.The performance of chgrp from non-privileged user will be
very slow, no matter if quota is enabled. Since we assume that
chgrp issued from non-privileged user is very rare, the performance
impact possibly is acceptable.
2.If MDT crash while performing chgrp, inconsistency (group ownership
among MDT and OST objects) will be created. It should be acceptable.

This patch has fixed the bug while calculating the disk space of
some file for ldiskfs and zfs, the block unit is always 512.

LU-10193 osd-zfs: backup index object with plain format

Lustre uses ZAP to implement index object. When tar the index

On the other hand, each backend FS has its own special format

LU-9564 build: Add server-build for Ubuntu with Kernel 4.4.0

This enables compatibility with the current LTS flavours of Ubuntu.
Do note that you need the Xenial HWE Kernel for Ubuntu 14.04.5, as
that distribution originally used a 3.x series Kernel.

The patches have been developed to apply cleanly to the kernel versions
4.4.0-45.66 to 4.4.0-85.108 from the Ubuntu Xenial (and its Trusty backports).

This change also adjusts the Debian scripting to produce the
ldiskfs modules and the server utilities.

To create the server modules run "./configure" with "--enable-server"
and specify "--enable-ldiskfs" and "--with-zfs/-spl" as appropriate.

The call to "make debs" will then produce the server modules and
utils instead of their client versions.

NOTE: This contains a small hack taken from LU-9995 / #29130

When set to 1, a client pertaining to this nodemap will be able to

When set to 0, events are not logged into the Changelogs, no matter

By default, audit_mode flag is set to 1 in newly created nodemap
entries. And it is also set to 1 on 'default' nodemap.

The idea of disabling audit on a per-nodemap basis is that it would
be possible to have some nodes (e.g. backup, HSM agent nodes) that do
not flood the audit logs.

LU-10513 acl: prepare small buffer for ACL RPC reply

For most of files, their ACL entries are very limited, under
such case, it is unnecessary to prepare very large reply buffer
to hold unknown-sized ACL entries for the getattr/open RPCs.
Instead, we can prepare some relative small buffer, such as the
LUSTRE_POSIX_ACL_MAX_SIZE_OLD (260) bytes, that is equal to the
ACL size before patch 64b2fad22a4eb4727315709e014d8f74c5a7f289.
If the target file has too many ACL entries and exceeds the
prepared reply buffer, then the MDT will reply -ERANGE failure
to the client, and then the client can prepare more large buffer
and try again. Since the file with large ACL is rare case, such
retrying getattr/open RPCs will not affect the real performance
too much.

The advantage is that it reduces the client side RAM pressure.

LU-10531 gss: fix GSS support for DNE

Part of the patch https://review.whamcloud.com/24236 was
inadvertently reverted by patch https://review.whamcloud.com/27823.
So re-apply missing part to have full DNE support in GSS code.

This patch is necessary because with DNE, an OSP can be used on MDT
for connections to other MDTs. So to determine exactly every
connection's purpose, use client_obd's cl_sp_to in
import_to_gss_svc().
