stack: use list_head for managing frames

2015-06-22T07:41:43+00:00

PROBLEM
--------

statedump requests that traverse call frames of all call stacks in
execution may race with a STACK_RESET on a stack.  This could crash the
corresponding glusterfs process. For e.g, recently we observed this in a
regression test case tests/basic/afr/sparse-self-heal.t.

FIX
---

gf_proc_dump_pending_frames takes a (TRY_LOCK) call_pool->lock before
iterating through call frames of all call stacks in progress.  With this
fix, STACK_RESET removes its call frames under the same lock.

Additional info
----------------

This fix makes call_stack_t to use struct list_head in place of custom
doubly-linked list implementation. This makes call_frame_t manipulation
easier to maintain in the context of STACK_WIND et al.

build: do not #include "config.h" in each file

2015-05-29T12:43:17+00:00

Instead of including config.h in each file, and have the additional
config.h included from the compiler commandline (-include option).

When a .c file tests for a certain #define, and config.h was not
included, incorrect assumtions were made. With this change, it can not
happen again.

features: add a directory-protection translator

2013-02-17T20:04:48+00:00

This is useful to find all calls that remove a file from the protected
directory, including renames and internal calls.  Such calls will cause
a stack trace to be logged.  There's a filter script to add the needed
translators, and then the new functionality can be invoked with one of
the following commands.

	setfattr -n trusted.glusterfs.protect -v log $dir
	setfattr -n trusted.glusterfs.protect -v reject $dir
	setfattr -n trusted.glusterfs.protect -v anything_else $dir

The first logs calls, but still allows them.  The second rejects them
with EPERM.  The third turns off protection for that directory.
