2009-05-06integrity: lsm audit rule matching fixMimi Zohar
An audit subsystem change replaced AUDIT_EQUAL with Audit_equal. Update calls to security_filter_rule_init()/match() to reflect the change. Signed-off-by: Mimi Zohar <zohar@us.ibm.com> Signed-off-by: James Morris <jmorris@namei.org>
2009-05-01do_wait: do take security_task_wait() into accountOleg Nesterov
I was never able to understand what should we actually do when security_task_wait() fails, but the current code doesn't look right. If ->task_wait() returns the error, we update *notask_error correctly. But then we either reap the child (despite the fact this was forbidden) or clear *notask_error (and hide the securiy policy problems). This patch assumes that "stolen by ptrace" doesn't matter. If selinux denies the child we should ignore it but make sure we report -EACCESS instead of -ECHLD if there are no other eligible children.

2009-04-30selinux: selinux_bprm_committed_creds() should wake up ->real_parent, not ↵Oleg Nesterov
->parent. We shouldn't worry about the tracer if current is ptraced, exec() must not succeed if the tracer has no rights to trace this task after cred changing. But we should notify ->real_parent which is, well, real parent. Also, we don't need _irq to take tasklist, and we don't need parent's ->siglock to wake_up_interruptible(real_parent->signal->wait_chldexit). Since we hold tasklist, real_parent->signal must be stable. Otherwise spin_lock(siglock) is not safe too and can't help anyway.

2009-04-30SELinux: Don't flush inherited SIGKILL during execve()David Howells
Don't flush inherited SIGKILL during execve() in SELinux's post cred commit hook. This isn't really a security problem: if the SIGKILL came before the credentials were changed, then we were right to receive it at the time, and should honour it; if it came after the creds were changed, then we definitely should honour it; and in any case, all that will happen is that the process will be scrapped before it ever returns to userspace.

2009-04-03don't raise all privs on setuid-root file with fE set (v2)Serge E. Hallyn
Distributions face a backward compatibility problem with starting to use file capabilities. For instance, removing setuid root from ping and doing setcap cap_net_raw=pe means that booting with an older kernel or one compiled without file capabilities means ping won't work for non-root users. In order to replace the setuid root bit on a capability-unaware program, one has to set the effective, or legacy, file capability, which makes the capability effective immediately. This patch uses the legacy bit as a queue to not automatically add full privilege to a setuid-root program. So, with this patch, an ordinary setuid-root program will run with privilege. But if /bin/ping has both setuid-root and cap_net_raw in fP and fE, then ping (when run by non-root user) will not run with only cap_net_raw.

2009-04-03modules: sysctl to block module loadingKees Cook
Implement a sysctl file that disables module-loading system-wide since there is no longer a viable way to remove CAP_SYS_MODULE after the system bounding capability set was removed in 2.6.25. Value can only be set to "1", and is tested only if standard capability checks allow CAP_SYS_MODULE. Given existing /dev/mem protections, this should allow administrators a one-way method to block module loading after initial boot-time module loading has finished.

2009-04-02Permissive domain in userspace object managerKaiGai Kohei
This patch enables applications to handle permissive domain correctly. Since the v2.6.26 kernel, SELinux has supported an idea of permissive domain which allows certain processes to work as if permissive mode, even if the global setting is enforcing mode. However, we don't have an application program interface to inform what domains are permissive one, and what domains are not. It means applications focuses on SELinux (XACE/SELinux, SE-PostgreSQL and so on) cannot handle permissive domain correctly. This patch add the sixth field (flags) on the reply of the /selinux/access interface which is used to make an access control decision from userspace. If the first bit of the flags field is positive, it means the required access control decision is on permissive domain, so application should allow any required actions, as the kernel doing. This patch also has a side benefit. The av_decision.flags is set at context_struct_compute_av(). It enables to check required permissions without read_lock(&policy_rwlock).

2009-03-28Annotate struct fs_struct's usage count restrictionDavid Howells
Annotate struct fs_struct's usage count to indicate the restrictions upon it. It may not be incremented, except by clone(CLONE_FS), as this affects the check in check_unsafe_exec() in fs/exec.c.

2009-03-28fix setuid sometimes wouldn'tHugh Dickins
check_unsafe_exec() also notes whether the fs_struct is being shared by more threads than will get killed by the exec, and if so sets LSM_UNSAFE_SHARE to make bprm_set_creds() careful about euid. But /proc/<pid>/cwd and /proc/<pid>/root lookups make transient use of get_fs_struct(), which also raises that sharing count. This might occasionally cause a setuid program not to change euid, in the same way as happened with files->count (check_unsafe_exec also looks at sighand->count, but /proc doesn't raise that one). We'd prefer exec not to unshare fs_struct: so fix this in procfs, replacing get_fs_struct() by get_fs_path(), which does path_get while still holding task_lock, instead of raising fs->count.

2009-03-28fix setuid sometimes doesn'tHugh Dickins
Joe Malicki reports that setuid sometimes doesn't: very rarely, a setuid root program does not get root euid; and, by the way, they have a health check running lsof every few minutes. Right, check_unsafe_exec() notes whether the files_struct is being shared by more threads than will get killed by the exec, and if so sets LSM_UNSAFE_SHARE to make bprm_set_creds() careful about euid. But /proc/<pid>/fd and /proc/<pid>/fdinfo lookups make transient use of get_files_struct(), which also raises that sharing count. There's a rather simple fix for this: exec's check on files->count has been redundant ever since 2.6.1 made it unshare_files() (except while compat_do_execve() omitted to do so) - just remove that check. [Note to -stable: this patch will not apply before 2.6.29: earlier releases should just remove the files->count line from unsafe_exec().] Reported-by: Joe Malicki <jmalicki@metacarta.com> Narrowed-down-by: Michael Itz <mitz@metacarta.com> Tested-by: Joe Malicki <jmalicki@metacarta.com> Signed-off-by: Hugh Dickins <hugh@veritas.com> Cc: stable@kernel.org Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2009-03-28compat_do_execve should unshare_filesHugh Dickins
2.6.26's commit fd8328be874f4190a811c58cd4778ec2c74d2c05 "sanitize handling of shared descriptor tables in failing execve()" moved the unshare_files() from flush_old_exec() and several binfmts to the head of do_execve(); but forgot to make the same change to compat_do_execve(), leaving a CLONE_FILES files_struct shared across exec from a 32-bit process on a 64-bit kernel. It's arguable whether the files_struct really ought to be unshared across exec; but 2.6.1 made that so to stop the loading binary's fd leaking into other threads, and a 32-bit process on a 64-bit kernel ought to behave in the same way as 32 on 32 and 64 on 64.

2009-03-28[ARM] 5435/1: fix compile warning in sanity_check_meminfo()Mikael Pettersson
Compiling recent 2.6.29-rc kernels for ARM gives me the following warning: arch/arm/mm/mmu.c: In function 'sanity_check_meminfo': arch/arm/mm/mmu.c:697: warning: comparison between pointer and integer This is because commit 3fd9825c42c784a59b3b90bdf073f49d4bb42a8d "[ARM] 5402/1: fix a case of wrap-around in sanity_check_meminfo()" in 2.6.29-rc5-git4 added a comparison of a pointer with PAGE_OFFSET, which is an integer. Fixed by casting PAGE_OFFSET to void *. Signed-off-by: Mikael Pettersson <mikpe@it.uu.se> Acked-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2009-03-28fastboot: remove duplicate unpack_to_rootfs()Li, Shaohua
we check if initrd is initramfs first and then do the real unpack. The check isn't required, we can directly do unpack. If the initrd isn't an initramfs, we can remove the garbage. In my laptop, this saves 0.1s boot time. This patch penalizes non-initramfs initrd case, but nowadays, initramfs is the most widely used method for initrds.

2009-03-28ide/net: flip the order of SATA and network initArjan van de Ven
this patch flips the order in which sata and network drivers are initialized. SATA probing takes quite a bit of time, and with the asynchronous infrastructure other drivers that run after it can execute in parallel. Network drivers do tend to take some real time talking to the hardware, so running these later is a good thing (the sata probe then runs concurrent) This saves about 15% of my kernels boot time. Both Dave and Jeff acked this patch and suggested it should go via the async tree. Signed-off-by: Arjan van de Ven <arjan@linux.intel.com> Acked-by: David S.
