It looks like memory leaks are “eating” 1G+ after only 1 week uptime … that's

I get 2 types of kmemleak backtraces, most likely 2 different issues, thus
2 seperate mails will follow as reply to this mail.

Does your system actually lose this memory or they are just be false positives? We've known since around 3.1 that kmemleak has some issues with per-cpu memory allocations and reporting false positives. The patches just went in (to be visible in 3.3-rc1). Alternatively, you could cherry-pick them from here: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=shortlog;h=029aeff5db879afd7760f11214b6fea45f76b58e (commit f528f0b8e5 "kmemleak: Handle percpu memory allocation" is the one you would need) Thanks. -- Catalin ^ permalink raw reply [flat|nested] 7+ messages in thread

Looks like lost memory.

The recompiled kernel has been running 22+ hours. A wdiff between dmesg reports from the previous and the new kernel shows nothing remarkable, kmemleak entries are similar. 3 entries in /var/log/messages “comm: modprobe”, too: grep -A8 '^2012-01-18T15.*kmemleak:' /var/log/messages 2012-01-18T15:07:58.888737+01:00 mobil kernel: [ 5.082708] kmemleak: Kernel memory leak detector initialized 2012-01-18T15:07:58.888738+01:00 mobil kernel: [ 5.082720] kmemleak: Automatic memory scanning thread started 2012-01-18T15:07:58.888739+01:00 mobil kernel: [ 5.088103] rtc_cmos 00:06: setting system clock to 2012-01-18 14:07:34 UTC (1326895654) 2012-01-18T15:07:58.888740+01:00 mobil kernel: [ 5.132408] XFS (sda21): Mounting Filesystem 2012-01-18T15:07:58.888740+01:00 mobil kernel: [ 5.237157] XFS (sda21): Ending clean mount 2012-01-18T15:07:58.888741+01:00 mobil kernel: [ 5.238499] VFS: Mounted root (xfs filesystem) readonly on device 259:5. 2012-01-18T15:07:58.888743+01:00 mobil kernel: [ 5.275538] devtmpfs: mounted 2012-01-18T15:07:58.888922+01:00 mobil kernel: [ 5.277644] Freeing unused kernel memory: 640k freed 2012-01-18T15:07:58.888924+01:00 mobil kernel: [ 6.465105] grsec: mount of proc to /proc by /bin/mount[mount:1093] uid/euid:0/0 gid/egid:0/0, parent /bin/bash[bash:1092] uid/euid:0/0 gid/egid:0/0 2012-01-18T15:07:58.888925+01:00 mobil kernel: [ 6.521311] grsec: mount of sysfs to /sys by /bin/mount[mount:1110] uid/euid:0/0 gid/egid:0/0, parent /bin/bash[bash:1109] uid/euid:0/0 gid/egid:0/0 -- 2012-01-18T15:21:05.610350+01:00 mobil kernel: [ 814.170102] kmemleak: Adding scan area to unknown object at 0xffffffffa0028280 2012-01-18T15:21:05.610370+01:00 mobil kernel: [ 814.170110] Pid: 5266, comm: modprobe Not tainted 3.1.6-grsecurity.roland.1 #2 2012-01-18T15:21:05.610374+01:00 mobil kernel: [ 814.170114] Call Trace: 2012-01-18T15:21:05.610380+01:00 mobil kernel: [ 814.170125] [<ffffffff81672f56>] kmemleak_scan_area+0x136/0x1a0 2012-01-18T15:21:05.610384+01:00 mobil kernel: [ 814.170134] [<ffffffff810bcb87>] load_module+0x687/0x1e40 2012-01-18T15:21:05.610388+01:00 mobil kernel: [ 814.170143] [<ffffffff81307d67>] ? gr_is_capable+0x27/0x40 2012-01-18T15:21:05.610392+01:00 mobil kernel: [ 814.170149] [<ffffffff810be3a0>] sys_init_module+0x60/0x1f0 2012-01-18T15:21:05.610396+01:00 mobil kernel: [ 814.170157] [<ffffffff81688e8d>] system_call_fastpath+0x18/0x1d 2012-01-18T15:21:05.622252+01:00 mobil kernel: [ 814.181353] snd_hda_intel 0000:01:00.1: PCI INT A -> GSI 16 (level, low) -> IRQ 16 -- 2012-01-18T15:21:06.005328+01:00 mobil kernel: [ 814.563803] kmemleak: Adding scan area to unknown object at 0xffffffffa002a5a0 2012-01-18T15:21:06.005355+01:00 mobil kernel: [ 814.563811] Pid: 5280, comm: modprobe Not tainted 3.1.6-grsecurity.roland.1 #2 2012-01-18T15:21:06.005359+01:00 mobil kernel: [ 814.563815] Call Trace: 2012-01-18T15:21:06.005365+01:00 mobil kernel: [ 814.563827] [<ffffffff81672f56>] kmemleak_scan_area+0x136/0x1a0 2012-01-18T15:21:06.005369+01:00 mobil kernel: [ 814.563836] [<ffffffff810bcb87>] load_module+0x687/0x1e40 2012-01-18T15:21:06.005374+01:00 mobil kernel: [ 814.563845] [<ffffffff81307d67>] ? gr_is_capable+0x27/0x40 2012-01-18T15:21:06.005378+01:00 mobil kernel: [ 814.563851] [<ffffffff810be3a0>] sys_init_module+0x60/0x1f0 2012-01-18T15:21:06.005382+01:00 mobil kernel: [ 814.563859] [<ffffffff81688e8d>] system_call_fastpath+0x18/0x1d 2012-01-18T15:21:06.070291+01:00 mobil kernel: [ 814.628812] kmemleak: Adding scan area to unknown object at 0xffffffffa00e1220 2012-01-18T15:21:06.070314+01:00 mobil kernel: [ 814.628820] Pid: 5286, comm: modprobe Not tainted 3.1.6-grsecurity.roland.1 #2 2012-01-18T15:21:06.070317+01:00 mobil kernel: [ 814.628824] Call Trace: 2012-01-18T15:21:06.070323+01:00 mobil kernel: [ 814.628835] [<ffffffff81672f56>] kmemleak_scan_area+0x136/0x1a0 2012-01-18T15:21:06.070327+01:00 mobil kernel: [ 814.628844] [<ffffffff810bcb87>] load_module+0x687/0x1e40 2012-01-18T15:21:06.070358+01:00 mobil kernel: [ 814.628852] [<ffffffff81307d67>] ? gr_is_capable+0x27/0x40 2012-01-18T15:21:06.070362+01:00 mobil kernel: [ 814.628858] [<ffffffff810be3a0>] sys_init_module+0x60/0x1f0 2012-01-18T15:21:06.070366+01:00 mobil kernel: [ 814.628867] [<ffffffff81688e8d>] system_call_fastpath+0x18/0x1d 2012-01-18T15:21:08.683225+01:00 mobil kernel: [ 817.234669] ADDRCONF(NETDEV_UP): eth0: link is not ready -- 2012-01-18T15:28:41.805266+01:00 mobil kernel: [ 1269.223947] kmemleak: 1 new suspected memory leaks (see /sys/kernel/debug/kmemleak) … So far no significant change in frequency or backtraces of kmemleak reports related to both of my issues.
