performance/md-cache: Fix a crash when statfs caching is enabled

2019-01-11T03:23:35+00:00

mem_put() in STACK_UNWIND_STRICT causes a crash if frame->local is not null
as md-cache obtains local from CALLOC.

Changed two occurrences of STACK_UNWIND_STRICT to MDC_STACK_UNWIND as
the latter macro does not rely on STACK_UNWIND_STRICT for cleaning up
frame->local.

New xlator option to control enable/disable of xlators in Gd2

2018-12-07T05:28:23+00:00

Since glusterd2 don't maintain the xlator option details in code, it
directly reads the xlators options table from `*.so` files. To support
enable and disable of xlator new option added to the option table with
the name same as xlator name itself.

This change will not affect the functionality with glusterd1.

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.

md-cache: extends xa_time when previous attributes equals cached attributes

2018-11-06T10:17:20+00:00

Some operations like read/write only update iatt and ia_time,
without any operion request xattrs from glusterfsd,
the xa_time is timeout before ia_time always.

This patch updates xa_time when update ia_ttime.

all: fix the format string exceptions

2018-11-05T18:50:59+00:00

Currently, there are possibilities in few places, where a user-controlled
(like filename, program parameter etc) string can be passed as 'fmt' for
printf(), which can lead to segfault, if the user's string contains '%s',
'%d' in it.

While fixing it, makes sense to make the explicit check for such issues
across the codebase, by making the format call properly.
