=== Description (from pull-request) ===
commit: https://github.com/lxc/lxc/commit/073135baa78511c26e502362840f2c950cfddfe2
change `sockname[sizeof(addr->sun_path)-2] = '\0';` to
`sockname[sizeof(addr->sun_path)-3] = '\0';` and can not explain the reason.
because we use `memset` to initialize `addr` to zero, we need not the code to make
sure that the last byte of addr is zero.
when delete this code, it doesn't seem to work, because the wrong check for abstract
socker addr's length in function `lxc_mointor_open`. The max length of the address
can be 107 bytes.
also fix this in function `lxc_abstract_unix_connect` and `lxc_abstract_unix_open`.

commit:
https://github.com/lxc/lxc/commit/073135baa78511c26e502362840f2c950cfddfe2
change `sockname[sizeof(addr->sun_path)-2] = '\0';` to
`sockname[sizeof(addr->sun_path)-3] = '\0';` and can not explain the
reason.
because we use `memset` to initialize `addr` to zero, we need not the code to
make
sure that the last byte of addr is zero.
when delete this code, it doesn't seem to work, because the wrong check for
abstract
socker addr's length in function `lxc_mointor_open`. The max length of the
address
can be 107 bytes.
also fix this in function `lxc_abstract_unix_connect` and
`lxc_abstract_unix_open`.

change `sockname[sizeof(addr->sun_path)-2] = '\0';` to
`sockname[sizeof(addr->sun_path)-3] = '\0';` and can not explain the reason.
because we use `memset` to initialize `addr` to zero, we need not the code to
make
sure that the last byte of addr is zero.
when delete this code, it doesn't seem to work, because the wrong check for
abstract
socker addr's length in function `lxc_mointor_open`. The max length of the
address
can be 107 bytes.
also fix this in function `lxc_abstract_unix_connect` and
`lxc_abstract_unix_open`.
