md-cache: Use correct xattr keynames for virtual glusterfs ACLs.

2017-10-25T14:05:54+00:00

The "glusterfs.posix_acl." prefix does not catch the glusterfs posix acl
xattr keynames which are

	* "glusterfs.posix.acl" and
	* "glusterfs.posix.default_acl"

Using the GF_POSIX_ACL_ACCESS and GF_POSIX_ACL_DEFAULT defines directly
is the savest option.

libgfchangelog: Fix possible null pointer dereference

2017-10-25T14:04:58+00:00

If pthread_attr_init fails, gf_msg uses this->name
where 'this' is not initialized yet. This patch fixes
the same.

glusterd: Gluster should keep PID file in correct location

2017-10-25T14:03:54+00:00

Currently Gluster keeps process pid information of all the daemons
and brick processes in Gluster configuration file directory
(ie., /var/lib/glusterd/*).

These pid files should be seperate from configuration files.
Deletion of the configuration file directory might result into serious problems.
Also, /var/run/gluster is the default placeholder directory for pid files.

So, with this fix Gluster will keep all process pid information of all
processes in /var/run/gluster/* directory.

features/worm: Adding check to newloc when doing rename

2017-10-25T14:03:28+00:00

Problem: Since rename didn't check if newloc exists and it's
retention state it was possible to rename a new file that wasn't
in retention over a existing file that was in read-only state.

glusterfsd: Dereferencing the null pointer

2017-10-25T14:00:31+00:00

Problem: When control reaches to out, one of (iobref, iobuf, frame) can
be null.for iobref, iobuf iobref_unref() and iobuf_unref() functions
are called respectively, which are using GF_VALIDATE_OR_GOTO(), so
there won't be null pointer dereference. But for frame without null
checking STACK_DESTROY(frame->root) is called causing null pointer
dereference.

Fix: adding a line for null checking, the function
STACK_DESTROY(frame->root) is called only when frame is not null.

md-cache: avoid checking the xattr value buffer with string functions.

2017-10-25T14:00:03+00:00

xattrs may very well contain binary, non-text data with leading 0
values. Using strcmp for checking empty values is not the appropriate
thing to do: In the best case, it might treat a binary xattr value
starting with 0 from being cached (and hence also from being reported
back with xattr). In the worst case, we might read beyond the end
of a data blob that does contain any zero byte.

We fix this by checking the length of the data blob and checking
the first byte against 0 if the length is one.

gfapi: set lkowner in glfd

2017-10-17T10:50:19+00:00

We need a provision to be able to set lkowner (which is
used to distinguish locks maintained by server) in gfapi.
Since the same lk_owner need to be used to be able to
flush the lock while closing the fd, store the lkowner
in the glfd structure itself.

A new API has been added to be able to set lkowner in glfd.

This is backport of below mainline fix -
