* stack: use list_head for managing framesKrishnan Parthasarathi2015-07-011-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Avoid conflict between contrib/uuid and system uuidEmmanuel Dreyfus2015-04-042-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | glusterfs relies on Linux uuid implementation, which API is incompatible with most other systems's uuid. As a result, libglusterfs has to embed contrib/uuid, which is the Linux implementation, on non Linux systems. This implementation is incompatible with systtem's built in, but the symbols have the same names. Usually this is not a problem because when we link with -lglusterfs, libc's symbols are trumped. However there is a problem when a program not linked with -lglusterfs will dlopen() glusterfs component. In such a case, libc's uuid implementation is already loaded in the calling program, and it will be used instead of libglusterfs's implementation, causing crashes. A possible workaround is to use pre-load libglusterfs in the calling program (using LD_PRELOAD on NetBSD for instance), but such a mechanism is not portable, nor is it flexible. A much better approach is to rename libglusterfs's uuid_* functions to gf_uuid_* to avoid any possible conflict. This is what this change attempts.

* build: split CPPFLAGS from CFLAGSJeff Darcy2012-10-031-2/+3
| | | | | | | | | | | | | | | | | Automake provides a separate variable for preprocessor flags (*_CPPFLAGS). They are already uses in a few places, so make it consistent and use it everywhere. Note that cflags obtained from pkg-config often are cppflags, which is why LIBXML2_CFLAGS moves with into AM_CPPFLAGS, for example.

* build: remove useless explicit -fPIC -shared fromJeff Darcy2012-10-031-2/+2
| | | | | | | | | | | | | | | | | | | | CFLAGS libtool will automatically add "-fPIC" to the compiler command line as needed, so there is no need to specify it separately. "-shared" is normally a linker flag and has an odd effect when used with libtool --mode=compile, namely that it inhibits production of static objects. For that however, using AC_DISABLE_STATIC is a lot simpler.
