api: versioned symbols in libgfapi.so for compatibility

2015-03-05T21:42:04+00:00

Use versioned symbols to keep libgfapi at libgfapi.so.0.0.0

Some nits uncovered:

+ there are a couple functions declared that do not have an
  associated definition, e.g. glfs_truncate(), glfs_caller_specific_init()

+ there are five private/internal functions used by heal/src/glfsheal
  and the gfapi master xlator (glfs-master.c): glfs_loc_touchup(),
  glfs_active_subvol(), and glfs_subvol_done(), glfs_init_done(),
  glfs_resolve_at(); which are not declared in glfs.h;

+ for this initial pass at versioned symbols, we use the earliest version
  of all public symbols, i.e. those for which there are declarations in
  glfs.h or glfs-handles.h.
  Further investigation as we do backports to 3.6, 3.4, and 3.4
  will be required to determine if older implementations need to
  be preserved (forward ported) and their associated alias(es) and
  symbol version(s) defined.

FWIW, we should consider linking all of our libraries with a map, it'll
result in a cleaner ABI. Perhaps something for an intern to do or a
Google Summer of Code project.

cluster/dht: Fixed double UNWIND in lookup everywhere code

2015-03-03T18:35:35+00:00

backport of http://review.gluster.org/#/c/8666/2 on master

In dht_lookup_everywhere_done:
At line 1107 we call DHT_STACK_UNWIND
and in the same if condition we go ahead and call, goto
unwind_hashed_and_cached; which at Line 1371 calls another UNWIND.

As is obvious, higher frames could cleanup their locals and on
receiving the next unwind could cause a coredump of the process.

Fixed the same by calling the required return post the first unwind

logrotate: gluster logrotate config should not be global

2014-10-30T15:31:38+00:00

Issue : Previously glusterfs logrotate config file pollutes
global config. So moved the directives inside the curly braces,
so they don't pollute the global config state.

cluster/afr: Handle EAGAIN properly in inodelk

2014-10-30T14:18:27+00:00

        Backport of http://review.gluster.org/8739

Problem:
When one of the brick is taken down and brough back up in a replica pair, locks
on that brick will be allowed. Afr returns inodelk success even when one of the
bricks already has the lock taken.

Fix:
If any brick returns EAGAIN return failure to parent xlator.

Note: This change only works for non-blocking inodelks. This patch addresses
dht-synchronization which uses non-blocking locks for rename. Blocking lock is
issued by only one of the rebalance processes. So for now there is no
possibility of deadlock.

socket: disallow CBC cipher modes

2014-10-29T17:31:40+00:00

This is related to CVE-2014-3566 a.k.a. POODLE.

	http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2014-3566

POODLE is specific to CBC cipher modes in SSLv3.  Because there is no
way to prevent SSLv3 fallback on a system with an unpatched version of
OpenSSL, users of such systems can only be protected by disallowing CBC
modes.  The default cipher-mode specification in our code has been
changed accordingly.
