Alexander Aring 2ebbe3a620 fs: dlm: fix memory leak when fenced ... [ Upstream commit 700ab1c363 ] I got some kmemleak report when a node was fenced. The user space tool dlm_controld will therefore run some rmdir() in dlm configfs which was triggering some memleaks. This patch stores the sps and cms attributes which stores some handling for subdirectories of the configfs cluster entry and free them if they get released as the parent directory gets freed. unreferenced object 0xffff88810d9e3e00 (size 192): comm "dlm_controld", pid 342, jiffies 4294698126 (age 55438.801s) hex dump (first 32 bytes): 00 00 00 00 00 00 00 00 73 70 61 63 65 73 00 00 ........spaces.. 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ backtrace: [<00000000db8b640b>] make_cluster+0x5d/0x360 [<000000006a571db4>] configfs_mkdir+0x274/0x730 [<00000000b094501c>] vfs_mkdir+0x27e/0x340 [<0000000058b0adaf>] do_mkdirat+0xff/0x1b0 [<00000000d1ffd156>] do_syscall_64+0x40/0x80 [<00000000ab1408c8>] entry_SYSCALL_64_after_hwframe+0x44/0xae unreferenced object 0xffff88810d9e3a00 (size 192): comm "dlm_controld", pid 342, jiffies 4294698126 (age 55438.801s) hex dump (first 32 bytes): 00 00 00 00 00 00 00 00 63 6f 6d 6d 73 00 00 00 ........comms... 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ backtrace: [<00000000a7ef6ad2>] make_cluster+0x82/0x360 [<000000006a571db4>] configfs_mkdir+0x274/0x730 [<00000000b094501c>] vfs_mkdir+0x27e/0x340 [<0000000058b0adaf>] do_mkdirat+0xff/0x1b0 [<00000000d1ffd156>] do_syscall_64+0x40/0x80 [<00000000ab1408c8>] entry_SYSCALL_64_after_hwframe+0x44/0xae Signed-off-by: Alexander Aring <aahringo@redhat.com> Signed-off-by: David Teigland <teigland@redhat.com> Signed-off-by: Sasha Levin <sashal@kernel.org>		2021-07-14 16:55:59 +02:00
