* stack: use list_head for managing framesKrishnan Parthasarathi2015-06-221-4/+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.

* build: do not #include "config.h" in each fileNiels de Vos2015-05-293-15/+0
| | | | | | | | | | | | | | | | | | 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.

* porting: Port for FreeBSD rebased from Mike Ma's effortsHarshavardhana2014-07-022-24/+26
| | | | | | | | | | | | | | | | | | | - Provides a working Gluster Management Daemon, CLI - Provides a working GlusterFS server, GlusterNFS server - Provides a working GlusterFS client - execinfo port from FreeBSD is moved into ./contrib/libexecinfo for ease of portability on NetBSD. (FreeBSD 10 and OSX provide execinfo natively) - More portability cleanups for Darwin, FreeBSD and NetBSD - Provides a new rc script for FreeBSD Change-Id: I8dff336f97479ca5a7f9b8c6b730051c0f8ac46f BUG: 1111774 Original-Author: Mike Ma <mikemandarine@gmail.com> Signed-off-by: Harshavardhana <harsha@harshavardhana.net> Reviewed-on: http://review.gluster.org/8141 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Kaleb KEITHLEY <kkeithle@redhat.com>
* build: do not create versioned <xlator>.so filesNiels de Vos2014-03-211-3/+3
| | | | | | | | | | | | | | | | | | There has been a misspelled option in the Makefile.am files. The option is called -avoid-version, and not -avoidversion. It is not trivial to provide a test-case for this. One way would be to check generated RPMs with a command like this (output should be empty): $ rpm -qlp *.rpm | grep -E '/xlator/.+.so.0' Change-Id: I2a6cc557eada4d098b73af5a254f8c75707543da BUG: 1078365 Signed-off-by: Niels de Vos <ndevos@redhat.com> Reviewed-on: http://review.gluster.org/7299 Reviewed-by: Lalatendu Mohanty <lmohanty@redhat.com> Reviewed-by: Kaleb KEITHLEY <kkeithle@redhat.com> Tested-by: Gluster Build System <jenkins@build.gluster.com>

* features: add a directory-protection translatorJeff Darcy2013-02-175-0/+458
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.
