* bdbuf: Fix race condition with sync active flagSebastian Huber2014-11-281-7/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bug report by Oleg Kravtsov: In rtems_bdbuf_swapout_processing() function there is the following lines: if (bdbuf_cache.sync_active && !transfered_buffers) { rtems_id sync_requester; rtems_bdbuf_lock_cache (); ... } Here access to bdbuf_cache.sync_active is not protected with anything. Imagine the following test case: 1. Task1 releases buffer(s) with bdbuf_release_modified() calls; 2. After a while swapout task starts and flushes all buffers; 3. In the end of that swapout flush we are before that part of code, and assume there is task switching (just before "if (bdbuf_cache.sync_active && !transfered_buffers)"); 4. Some other task (with higher priority) does bdbuf_release_modified and rtems_bdbuf_syncdev(). This task successfully gets both locks sync and pool (in rtems_bdbuf_syncdev() function), sets sync_active to true and starts waiting for RTEMS_BDBUF_TRANSFER_SYNC event with only sync lock got. 5. Task switching happens again and we are again before "if (bdbuf_cache.sync_active && !transfered_buffers)". As the result we check sync_active and we come inside that "if" statement. 6. The result is that we send RTEMS_BDBUF_TRANSFER_SYNC event! Though ALL modified messages of that task are not flushed yet! close #1485

* libblock: PR2040: Avoid NULL pointer accessSebastian Huber2013-08-231-6/+16
| | | | | | | This partly reverts commit 08b9d534604fbf437743a9925ef28eb1b848510d. Avoid a NULL pointer access and perform the source segment erase if necessary.

| | | | | Check the availablity of a recycle destination segment only when it is necessary to avoid missing resycle source segment erasures.
* libblock: PR2040: Add starvation thresholdSebastian Huber2012-04-161-1/+15
| | | | | | Do not use the unavailable block count as the erased blocks starvation threshold. Use instead the block count of the largest segment. This improves the starvation resolution gain of available blocks.

* PR2040: libblock: Avoid erased blocks starvationSebastian Huber2012-03-141-115/+185
| | | | | | | | | | | | The compaction process needs erased blocks. It is only possible to erase an entire segment. Thus in order to make a progress we always need enough erased blocks to empty a used or available segment which can be erased in turn. A (possibly the worst case) lower bound of erased blocks is the block count of the largest segment. The number of unavailable blocks specified by the configuration will be used to determine the erase blocks starvation situation. The number of unavailable blocks must be greater than or equal to the number of blocks in the largest segment.
