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.

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.

All: run codespell on the code and fix issues.

Please review, it's not always just the comments that were fixed.
I've had to revert of course all calls to creat() that were changed
to create() ...

Only compile-tested!

libglusterfs/atomic: Improved atomic support

2017-11-14T05:22:00+00:00

This patch solves a detection problem in configure.ac that prevented
that compilation detects builtin __atomic or __sync functions.

It also adds more atomic types and support for other atomic functions.

An special case has been added to support 64-bit atomics on 32-bit
systems. The solution is to fallback to the mutex solution only for
64-bit atomics, but smaller atomic types will still take advantage
of builtins if available.

nl-cache: Fix a possible crash and stale cache

2017-06-13T05:01:17+00:00

Issue1:
Consider the followinf sequence of operations:
   ...
   nlc_ctx = nlc_ctx_get (inode i1)
   ....... -> nlc_clear_cache (i1) gets called as a part of nlc_invalidate
                                   or any other callers
              ...
              GF_FREE (ii nlc_ctx)
   LOCK (nlc_ctx->lock);  ->  This will result in crash as the ctx
                              got freed in nlc_clear_cache.

Issue2:
   lookup on dir1/file1 result in ENOENT
   add cache to dir1 at time T1
   ....
   CHILD_DOWN at T2
   lookup on dir1/file2 result in ENOENT
   add cache to dir1, but the cache time is still T1
   lookup on dir1/file2 - should have been served from cache
                          but the cache time is T1 < T2, hence
                          cache is considered as invalid.
So, after CHILD_DOWN the right thing would be to clear the cache
and restart caching on that inode.

Solution:
Do not free nlc_ctx in nlc_clear_cache, but only in inode_forget()
The fix for both issue1 and 2 is interleaved hence sending it as
single patch.
