[seccomp] kernel BUG at kernel/fork.c:1102!

by Fengguang Wu

Greetings, 0day kernel testing robot got the below dmesg and the first bad commit is commit dbd952127d11bb44a4ea30b08cc60531b6a23d71 Author: Kees Cook <keescook(a)chromium.org> AuthorDate: Fri Jun 27 15:18:48 2014 -0700 Commit: Kees Cook <keescook(a)chromium.org> CommitDate: Fri Jul 18 12:13:39 2014 -0700 seccomp: introduce writer locking Normally, task_struct.seccomp.filter is only ever read or modified by the task that owns it (current). This property aids in fast access during system call filtering as read access is lockless. Updating the pointer from another task, however, opens up race conditions. To allow cross-thread filter pointer updates, writes to the seccomp fields are now protected by the sighand spinlock (which is shared by all threads in the thread group). Read access remains lockless because pointer updates themselves are atomic. However, writes (or cloning) often entail additional checking (like maximum instruction counts) which require locking to perform safely. In the case of cloning threads, the child is invisible to the system until it enters the task list. To make sure a child can't be cloned from a thread and left in a prior state, seccomp duplication is additionally moved under the sighand lock. Then parent and child are certain have the same seccomp state when they exit the lock. Based on patches by Will Drewry and David Drysdale.

[LSM] Kernel panic - not syncing: Could not register security module

by Fengguang Wu

Hi Kees, FYI, this bug seems still not fixed in your updated tree. git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux.git lsm/mnt-restrict commit 98d51ac605984b0306dfa8d4e99f027d894b3cee Author: Kees Cook <keescook(a)chromium.org> AuthorDate: Sat Sep 21 15:52:51 2013 -0700 Commit: Kees Cook <keescook(a)chromium.org> CommitDate: Tue Nov 4 13:39:48 2014 -0800 LSM: MntRestrict blocks mounts on symlink targets On systems where certain filesystem contents cannot be entirely trusted, it is beneficial to block mounts on symlinks. This makes sure that malicious filesystem contents cannot trigger the over-mounting of trusted 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.)

[LSM] Kernel panic - not syncing: No working init found.

by Fengguang Wu

Greetings, 0day kernel testing robot got the below dmesg and the first bad commit is git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux.git lsm/stacking commit 70bba377802ad16dda270ec02098289c16abdc3c Author: Casey Schaufler <casey(a)schaufler-ca.com> AuthorDate: Thu Oct 16 17:48:26 2014 -0700 Commit: Kees Cook <keescook(a)chromium.org> CommitDate: Fri Oct 31 09:26:42 2014 -0700 LSM: Refactor existing LSM stacking The existing code stacks up to three security modules. If there is only one module it is the capability module. If a module is specified the capability code is explicitly called within the specified module. If Yama stacking is configured the yama hooks are called and then the specified module. The capability check is made twice in the yama stacking case. This patch adds a list for each of the LSM hooks. The capability hooks that are non-trivial are put on the list first. If Yama stacking is configured the yama hooks are added to the list. If a module is configured it gets added next. Each entry in the list is called in order: (capability[ yama][ {selinux|smack|tomoyo|apparmor}]) Exit is on first failure (bail on fail) which matches the existing behavior. The explict calls to the capability module are removed where they would duplicate the stacked call. The comment on the vm_enough_memory hook reflects the revised behavior. The return value of selinux_bprm_secureexec is corrected. The selinux_inode_getsecurity hook check capabilities as it should. Signed-off-by: Casey Schaufler <casey(a)schaufler-ca.com> --- This reflects comments made by Stephen Smalley on patch v17 2/4 in the set. Fixes Yama rc=0 bug. +------------------------------------------------+------------+------------+------------+ | | a89172c815 | 70bba37780 | 43742f5901 | +------------------------------------------------+------------+------------+------------+ | boot_successes | 60 | 0 | 0 | | boot_failures | 0 | 20 | 60 | | Kernel_panic-not_syncing:No_working_init_found | 0 | 20 | 60 | | backtrace:panic | 0 | 20 | 60 | +------------------------------------------------+------------+------------+------------+ [ 3.405174] Starting init: /sbin/init exists but couldn't execute it (error -12) [ 3.406262] Starting init: /etc/init exists but couldn't execute it (error -13) [ 3.407381] Starting init: /bin/sh exists but couldn't execute it (error -12) [ 3.408446] Kernel panic - not syncing: No working init found.
