Due to integer variables alignment size of struct autofs_v5_packet in 300 bytes in 32-bit architectures (instead of 304 bytes in 64-bits architectures).
This may lead to memory corruption (64 bits kernel always send 304 bytes, while 32-bit userspace application expects for 300). https://jira.sw.ru/browse/PSBM-71078 Signed-off-by: Stanislav Kinsburskiy <skinsbur...@virtuozzo.com> --- include/uapi/linux/auto_fs4.h | 2 ++ 1 file changed, 2 insertions(+) diff --git a/include/uapi/linux/auto_fs4.h b/include/uapi/linux/auto_fs4.h index e02982f..8729a47 100644 --- a/include/uapi/linux/auto_fs4.h +++ b/include/uapi/linux/auto_fs4.h @@ -137,6 +137,8 @@ struct autofs_v5_packet { __u32 pid; __u32 tgid; __u32 len; + __u32 blob; /* This is needed to align structure up to 8 + bytes for ALL archs including 32-bit */ char name[NAME_MAX+1]; }; _______________________________________________ Devel mailing list Devel@openvz.org https://lists.openvz.org/mailman/listinfo/devel
