[linux-lvm] lvmetad crashes with “memory smash” during lvm parallel operations

Hi,

We went through the code on the this issue and able to point out that the structure memblock in
unprotected from parallel threads.

void dm_bounds_check_debug(void)
{
struct memblock *mb = _head;
while (mb) {
size_t i;
char *ptr = ((char *) (mb + 1)) + mb->length;
for (i = 0; i < sizeof(unsigned long); i++)
if (*ptr++ != (char) mb->id)
assert(!"Memory smash");

mb = mb->next;
}
}

So, if in case another thread try to access remove an entry and at the same time of query of the
list, the lvmetad will crash. It is good have a lock introduced to memoryblock structure.

Hi ,
Greetings.
We are facing an issue with LVMETAD crashing during the parallel lvm operations
(vgscan/pvscan/lvscan/lvs/vgs)
PKG_NAME=LVM2
PKG_VERSION=2.02.168
PKG_URL=LVM2.2.02.168.tgz
PKG_MD5=00209bdd6befe9a7330f162909313ae8
PKG_DATE=2016-12-01
This issue is also seen in LVM2-2.02.171.
The issue is reproduced on the MIPS Architecture HARDWARE with SCSI DISKS.
Device: TOSHIBA AL13SEB600 Version: 4701
Serial number: 54R0A04HFYP6
Device type: disk
Transport protocol: SAS

(int)

So we enabled the debug flag to see the lvmetad operation . I could see that the vg_list
operation
is overlapping the from the other thread and causing the leak in linked list and consequent
"memory
smash" for LVMETAD.
