Pull audit fixes from Paul Moore: "Four patches to fix various problems with the audit subsystem, all are fairly small and straightforward. One patch fixes a problem where we weren't using the correct gfp allocation flags (GFP_KERNEL regardless of context, oops), one patch fixes a problem with old userspace tools (this was broken for a while), one patch fixes a problem where we weren't recording pathnames correctly, and one fixes a problem with PID based filters.

A regression was caused by commit 780a7654: audit: Make testing for a valid loginuid explicit. (which in turn attempted to fix a regression caused by e1760bd5 ) When audit_krule_to_data() fills in the rules to get a listing, there was a missing clause to convert back from AUDIT_LOGINUID_SET to AUDIT_LOGINUID. This broke userspace by not returning the same information that was sent and expected. The rule: auditctl -a exit,never -F auid=-1 gives: auditctl -l LIST_RULES: exit,never f24=0 syscall=all when it should give: LIST_RULES: exit,never auid=-1 (0xffffffff) syscall=all Tag it so that it is reported the same way it was set. Create a new private flags audit_krule field (pflags) to store it that won't interact with the public one from the API. Cc: stable@vger.kernel.org # v3.10-rc1+ Signed-off-by:

On arm64 the TTBR0_EL1 register is set to either the reserved TTBR0 page tables on boot or to the active_mm mappings belonging to user space processes, it must never be set to swapper_pg_dir page tables mappings. When a CPU is booted its active_mm is set to init_mm even though its TTBR0_EL1 points at the reserved TTBR0 page mappings. This implies that when __cpu_suspend is triggered the active_mm can point at init_mm even if the current TTBR0_EL1 register contains the reserved TTBR0_EL1 mappings. Therefore, the mm save and restore executed in __cpu_suspend might turn out to be erroneous in that, if the current->active_mm corresponds to init_mm, on resume from low power it ends up restoring in the TTBR0_EL1 the init_mm mappings that are global and can cause speculation of TLB entries which end up being propagated to user space. This patch fixes the issue by checking the active_mm pointer before restoring the TTBR0 mappings. If the current active_mm == &init_mm, the code sets the TTBR0_EL1 to the reserved TTBR0 mapping instead of switching back to the active_mm, which is the expected behaviour corresponding to the TTBR0_EL1 settings when __cpu_suspend was entered.

There is a problem with the audit system when multiple audit records are created for the same path, each with a different path name type. The root cause of the problem is in __audit_inode() when an exact match (both the path name and path name type) is not found for a path name record; the existing code creates a new path name record, but it never sets the path name in this record, leaving it NULL. This patch corrects this problem by assigning the path name to these newly created records. There are many ways to reproduce this problem, but one of the easiest is the following (assuming auditd is running): # mkdir /root/tmp/test # touch /root/tmp/test/567 # auditctl -a always,exit -F dir=/root/tmp/test # touch /root/tmp/test/567 Afterwards, or while the commands above are running, check the audit log and pay special attention to the PATH records. A faulty kernel will display something like the following for the file creation: type=SYSCALL msg=audit(1416957442.025:93): arch=c000003e syscall=2 success=yes exit=3 ... comm="touch" exe="/usr/bin/touch" type=CWD msg=audit(1416957442.025:93): cwd="/root/tmp" type=PATH msg=audit(1416957442.025:93): item=0 name="test/" inode=401409 ... nametype=PARENT type=PATH msg=audit(1416957442.025:93): item=1 name=(null) inode=393804 ... nametype=NORMAL type=PATH msg=audit(1416957442.025:93): item=2 name=(null) inode=393804 ... nametype=NORMAL While a patched kernel will show the following: type=SYSCALL msg=audit(1416955786.566:89): arch=c000003e syscall=2 success=yes exit=3 ... comm="touch" exe="/usr/bin/touch" type=CWD msg=audit(1416955786.566:89): cwd="/root/tmp" type=PATH msg=audit(1416955786.566:89): item=0 name="test/" inode=401409 ... nametype=PARENT type=PATH msg=audit(1416955786.566:89): item=1 name="test/567" inode=393804 ... nametype=NORMAL This issue was brought up by a number of people, but special credit should go to hujianyang@huawei.com for reporting the problem along with an explanation of the problem and a patch. While the original patch did have some problems (see the archive link below), it did demonstrate the problem and helped kickstart the fix presented here. * https://lkml.org/lkml/2014/9/5/66 Reported-by:

The previous cleanup of BMC attributes left a few holes, and if you run with lockdep debugging with a BMC with the proper attributes, you could get a warning. This patch removes all the unused attributes from the BMC structure, since they are all declared in the .data section now. It makes the attributes all static. It fixes the referencing of the attributes in a couple of cases that dynamically added the files depending on BMC information. Signed-off-by:

Eric Paris explains: Since kauditd_send_multicast_skb() gets called in audit_log_end(), which can come from any context (aka even a sleeping context) GFP_KERNEL can't be used. Since the audit_buffer knows what context it should use, pass that down and use that.

Commit f1dc4867 ("audit: anchor all pid references in the initial pid namespace") introduced a find_vpid() call when adding/removing audit rules with PID/PPID filters; unfortunately this is problematic as find_vpid() only works if there is a task with the associated PID alive on the system. The following commands demonstrate a simple reproducer. # auditctl -D # auditctl -l # autrace /bin/true # auditctl -l This patch resolves the problem by simply using the PID provided by the user without any additional validation, e.g. no calls to check to see if the task/PID exists.

Move pinmux alloc/dealloc code into functions that don't take the spinlock so we can use from code that has the spinlock already. CRISv32 has no working SMP, so spinlocks becomes a NOP, so deadlock was never seen. Signed-off-by:
