|
@ Split ccs_null_security into ccs_default_security and ccs_oom_security. |
| 2703 |
|
|
| 2704 |
|
ccs_null_security is used by preserve KABI compatibility option and is |
| 2705 |
|
used for providing default values against threads which have not yet |
| 2706 |
|
allocated memory for their security contexts. |
| 2707 |
|
|
| 2708 |
|
If current thread failed to allocate memory for current thread's security |
| 2709 |
|
context, current thread uses ccs_null_security. Since current thread is |
| 2710 |
|
allowed to modify current thread's security context, current thread might |
| 2711 |
|
modify ccs_null_security which should not be modified for any reason. |
| 2712 |
|
|
| 2713 |
|
Therefore, I split ccs_null_security into ccs_default_security and |
| 2714 |
|
ccs_oom_security and use ccs_oom_security when current thread failed to |
| 2715 |
|
allocate memory for current thread's security context. |
| 2716 |
|
|
| 2717 |
|
Threads which do not share ccs_oom_security are not affected by threads |
| 2718 |
|
which share ccs_oom_security. Threads which share ccs_oom_security will |
| 2719 |
|
experience temporary inconsistency, but such threads are about to be |
| 2720 |
|
killed by SIGKILL signal. |

@ Use filesystem name for unnamed devices when vfsmount is missing. |
| 2725 |
|
|
| 2726 |
|
"Change pathname for non-rename()able filesystems." changed to use |
| 2727 |
|
"$fsname:" if the filesystem does not support rename() operation and |
| 2728 |
|
"dev($major,$minor):" otherwise when vfsmount is missing. But it turned |
| 2729 |
|
out that it is useless to use "dev($major,$minor):" for unnamed devices |
| 2730 |
|
(filesystems with $major == 0). Thus, I changed to use "$fsname:" rather |
| 2731 |
|
than "dev($major,$minor):" for filesystems with $major == 0 when vfsmount |
| 2732 |
|
is missing. |

|
@ Fix infinite loop bug when reading /proc/ccs/audit or /proc/ccs/query . |
| 2737 |
|
|
| 2738 |
|
In ccs_flush(), head->r.w[0] holds pointer to string data to be printed. |
| 2739 |
|
But head->r.w[0] was updated only when the string data was partially |
| 2740 |
|
printed (because head->r.w[0] will be updated by head->r.w[1] later if |
| 2741 |
|
completely printed). However, regarding /proc/ccs/audit and |
| 2742 |
|
/proc/ccs/query , an additional '\0' is printed after the string data was |
| 2743 |
|
completely printed. But if free space for read buffer became 0 before |
| 2744 |
|
printing the additional '\0', ccs_flush() was returning without updating |
| 2745 |
|
head->r.w[0]. As a result, ccs_flush() forever reprints already printed |
| 2746 |
|
string data. |
