[Patch] upstream fix against the current master (25be7b9)
Note that leaked file descriptors produce also several AVCs, like mdadm accessing /dev/mapper/control. Fixed by upstream commit dc64a4d3c74fd90f61 (master) in python-blivet-0.24-1 (f21/rawhide) and python-blivet-0.23.2-1 (f20). |
Description of problem: When working with lvm from blivet, I keep seeing messages like this in the log: " INFO:program: Running... lvm pvs --unit=k --nosuffix --nameprefixes --rows --unquoted --noheadings -opv_uuid,pe_start,vg_name,vg_uuid,vg_size,vg_free,vg_extent_size,vg_extent_count,vg_free_count,pv_count --config global {locking_type=4} /dev/vda4 INFO:program: File descriptor 8 (/dev/mapper/control) leaked on lvm invocation. Parent PID 19615: python " Those may not be a problem, but they are a real problem if blivet tries to parse the output of an external program and instead of the real output, it gets something like "File descriptor 8 (/dev/mapper/control) leaked on lvm invocation. Parent PID 19976: python". Version-Release number of selected component (if applicable): python-blivet-0.22-1.fc21.noarch How reproducible: Always Steps to Reproduce: 1. run blivet so it executes thinlvpoolname() in devicelibs/lvm.py 2. observe the output returned by the function Actual results: Output contains "File descriptor 8 (/dev/mapper/control) leaked on lvm invocation..." message and not the real output. Expected results: Output contains the name of the thin pool name as expected. Additional info:
