core: make compute_cksum function op_version compatible

2019-03-08T14:45:41+00:00

Problem: commit 5a152a changed the mechansim of computing the
checksum. In heterogeneous cluster, peers are running into
rejected state because we have different cksum computation
mechansims in upgraded and non-upgraded nodes.

Solution: add a check for op-version so that all the nodes
in the cluster follow the same mechanism for computing the
cksum.

core: make gf_thread_create() easier to use

2019-02-01T09:37:20+00:00

This patch creates a specific function to set the thread name using a
string format and a variable argument list, like printf().

This function is used to set the thread name from gf_thread_create(),
which now accepts a variable argument list to create the full name. It's
not necessary anymore to use a local array to build the name of the
thread. This is done automatically.

afr/self-heal:Fix wrong type checking

2019-01-24T12:16:50+00:00

gf_dirent struct has d_type variable which should check
with DT_DIR istead of IA_IFDIR or IA_IFDIR has to compare
with entry->d_stat.ia_type

rpc: use address-family option from vol file

2019-01-22T13:47:19+00:00

This patch helps enable IPv6 connections in the cluster.
The default address-family is IPv4 without using this option explicitly.

When address-family is set to "inet6" in the /etc/glusterfs/glusterd.vol
file, the mount command-line also needs to have
-o xlator-option="transport.address-family=inet6" added to it.

This option also gets added to the brick command-line.
Snapshot and gfapi use-cases should also use this option to pass in the
inet6 address-family.

core: Feature added to accept CidrIp in auth.allow

2019-01-18T17:13:13+00:00

Added functionality to gluster volume set auth.allow command to
accept CIDR IP addresses. Modified few functions to isolate cidr
feature so that it prevents other gluster commands such as peer
probe to use cidr format ip. The functions are modified in such
a way that they have an option to enable accepting of cidr
format for other gluster commands if required in furture.

cluster/afr: Allow lookup on root if it is from ADD_REPLICA_MOUNT

2018-12-18T10:30:19+00:00

Problem: When trying to convert a plain distribute volume to replica-3
or arbiter type it is failing with ENOTCONN error as the lookup on
the root will fail as there is no quorum.

Fix: Allow lookup on root if it is coming from the ADD_REPLICA_MOUNT
which is used while adding bricks to a volume. It will try to set the
pending xattrs for the newly added bricks to allow the heal to happen
in the right direction and avoid data loss scenarios.

Note: This fix will solve the problem of type conversion only in the
case where the volume was mounted at least once. The conversion of
non mounted volumes will still fail since the dht selfheal tries to
set the directory layout will fail as they do that with the PID
GF_CLIENT_PID_NO_ROOT_SQUASH set in the frame->root.

mem-pool: Add api to mem_get based on requested size

2018-12-17T17:26:59+00:00

Currently mem-pool implementation provides api to get from the
mem pool based on the struct type. This is to retain api
compatibility with the old implementation of mem pool. Internally
in the mem pool structure there is a mapping from struct to size
based pools.

In this patch, we are adding new APIs to fetch memory from mem pool,
given a size.

libglusterfs: Move devel headers under glusterfs directory

2018-12-05T21:47:04+00:00

libglusterfs devel package headers are referenced in code using
include semantics for a program, this while it works can be better
especially when dealing with out of tree xlator builds or in
general out of tree devel package usage.

Towards this, the following changes are done,
- moved all devel headers under a glusterfs directory
- Included these headers using system header notation <> in all
code outside of libglusterfs
- Included these headers using own program notation "" within
libglusterfs

This change although big, is just moving around the headers and
making it correct when including these headers from other sources.

This helps us correctly include libglusterfs includes without
namespace conflicts.
