This makes sure that malicious filesystem contents cannot trigger the over-mounting of trust= ed filesystems. (For example, a bind-mounted subdirectory of /var cannot be redirected to mount on /etc via a symlink: a daemon cannot elevate privs to uid-0.) =20 Signed-off-by: Kees Cook +-------------------------------------------------------------+------------= +------------+------------------+ | | 7505ceaf86 = | d9df832e0c | v3.17-rc3_090307 | +-------------------------------------------------------------+------------= +------------+------------------+ | boot_successes | 183 = | 0 | 0 | | boot_failures | 57 = | 20 | 21 | | BUG:kernel_boot_hang | 57 = | | | | Kernel_panic-not_syncing:Could_not_register_security_module | 0 = | 20 | 21 | | backtrace:panic | 0 = | 20 | 21 | | backtrace:mntrestrict_init | 0 = | 20 | 21 | | backtrace:security_init | 0 = | 20 | 21 | +-------------------------------------------------------------+------------= +------------+------------------+ [ 0.008000] ACPI: Core revision 20140724 [ 0.009549] ACPI: All ACPI Tables successfully acquired [ 0.010749] Security Framework initialized [ 0.012012] Kernel panic - not syncing: Could not register security modu= le [ 0.013779] CPU: 0 PID: 0 Comm: swapper/0 Not tainted 3.17.0-rc3-00003-g= d9df832 #6 [ 0.016000] Hardware name: Bochs Bochs, BIOS Bochs 01/01/2011 [ 0.016000] 0000000000000000 ffffffff81a03eb0 ffffffff81563273 ffffffff= 817aad75 [ 0.016000] ffffffff81a03f28 ffffffff8155e113 ffffffff00000008 ffffffff= 81a03f38 [ 0.016000] ffffffff81a03ed8 00000000000143c0 ffffffff81b4d998 00000000= 80000000 [ 0.016000] Call Trace: [ 0.016000] [] dump_stack+0x4e/0x7a [ 0.016000] [] panic+0xc6/0x1d8 [ 0.016000] [] mntrestrict_init+0x37/0x49 [ 0.016000] [] security_init+0x3c/0x47 [ 0.016000] [] start_kernel+0x38d/0x3c7 [ 0.016000] [] ?
