2012-01-17audit: fix signedness bug in audit_log_execve_info()Xi Wang
In the loop, a size_t "len" is used to hold the return value of audit_log_single_execve_arg(), which returns -1 on error. In that case the error handling (len <= 0) will be bypassed since "len" is unsigned, and the loop continues with (p += len) being wrapped. Change the type of "len" to signed int to fix the error handling. size_t len; ... for (...) { len = audit_log_single_execve_arg(...); if (len <= 0) break; p += len; } Signed-off-by: Xi Wang <xi.wang@gmail.com> Signed-off-by: Eric Paris <eparis@redhat.com>

2012-01-17audit: allow interfield comparison in audit rulesEric Paris
We wish to be able to audit when a uid=500 task accesses a file which is uid=0. Or vice versa. This patch introduces a new audit filter type AUDIT_FIELD_COMPARE which takes as an 'enum' which indicates which fields should be compared. At this point we only define the task->uid vs inode->uid, but other comparisons can be added. Signed-off-by: Eric Paris <eparis@redhat.com>
2012-01-17audit: do not call audit_getname on errorEric Paris

2012-01-17audit: only allow tasks to set their loginuid if it is -1Eric Paris
At the moment we allow tasks to set their loginuid if they have CAP_AUDIT_CONTROL. In reality we want tasks to set the loginuid when they log in and it be impossible to ever reset. We had to make it mutable even after it was once set (with the CAP) because on update and admin might have to restart sshd. Now sshd would get his loginuid and the next user which logged in using ssh would not be able to set his loginuid. Systemd has changed how userspace works and allowed us to make the kernel work the way it should. With systemd users (even admins) are not supposed to restart services directly. The system will restart the service for them. Thus since systemd is going to loginuid==-1, sshd would get -1, and sshd would be allowed to set a new loginuid without special permissions. If an admin in this system were to manually start an sshd he is inserting himself into the system chain of trust and thus, logically, it's his loginuid that should be used! Since we have old systems I make this a Kconfig option. Signed-off-by: Eric Paris <eparis@redhat.com>

2012-01-17audit: remove audit_finish_fork as it can't be calledEric Paris
Audit entry,always rules are not allowed and are automatically changed in exit,always rules in userspace. The kernel refuses to load such rules. Thus a task in the middle of a syscall (and thus in audit_finish_fork()) can only be in one of two states: AUDIT_BUILD_CONTEXT or AUDIT_DISABLED. Since the current task cannot be in AUDIT_RECORD_CONTEXT we aren't every going to actually use the code in audit_finish_fork() since it will return without doing anything. Thus drop the code.

2012-01-17audit: inline checks for not needing to collect aux recordsEric Paris

2012-01-17audit: inline audit_syscall_entry to reduce burden on archsEric Paris
Every arch calls: if (unlikely(current->audit_context)) audit_syscall_entry() which requires knowledge about audit (the existance of audit_context) in the arch code. Just do it all in static inline in audit.h so that arch's can remain blissfully ignorant. Signed-off-by: Eric Paris <eparis@redhat.com>
2012-01-17Audit: push audit success and retcode into arch ptrace.hEric Paris
The audit system previously expected arches calling to audit_syscall_exit to supply as arguments if the syscall was a success and what the return code was. Audit also provides a helper AUDITSC_RESULT which was supposed to simplify things by converting from negative retcodes to an audit internal magic value stating success or failure. This helper was wrong and could indicate that a valid pointer returned to userspace was a failed syscall. The fix is to fix the layering foolishness. We now pass audit_syscall_exit a struct pt_reg and it in turns calls back into arch code to collect the return value and to determine if the syscall was a success or failure. We also define a generic is_syscall_success() macro which determines success/failure based on if the value is < -MAX_ERRNO. This works for arches like x86 which do not use a separate mechanism to indicate syscall failure. We make both the is_syscall_success() and regs_return_value() static inlines instead of macros. The reason is because the audit function must take a void* for the regs. (uml calls theirs struct uml_pt_regs instead of just struct pt_regs so audit_syscall_exit can't take a struct pt_regs). Since the audit function takes a void* we need to use static inlines to cast it back to the arch correct structure to dereference it. The other major change is that on some arches, like ia64, MIPS and ppc, we change regs_return_value() to give us the negative value on syscall failure. THE only other user of this macro, kretprobe_example.c, won't notice and it makes the value signed consistently for the audit functions across all archs. In arch/sh/kernel/ptrace_64.c I see that we were using regs[9] in the old audit code as the return value. But the ptrace_64.h code defined the macro regs_return_value() as regs[3]. I have no idea which one is correct, but this patch now uses the regs_return_value() function, so it now uses regs[3]. For powerpc we previously used regs->result but now use the regs_return_value() function which uses regs->gprs[3]. regs->gprs[3] is always positive so the regs_return_value(), much like ia64 makes it negative before calling the audit code when appropriate.

2012-01-17seccomp: audit abnormal end to a process due to seccompEric Paris

2012-01-17audit: check current inode and containing object when filtering on major and ↵Eric Paris
minor The audit system has the ability to filter on the major and minor number of the device containing the inode being operated upon. Lets say that /dev/sda1 has major,minor 8,1 and that we mount /dev/sda1 on /boot. Now lets say we add a watch with a filter on 8,1. If we proceed to open an inode inside /boot, such as /vboot/vmlinuz, we will match the major,minor filter. Lets instead assume that one were to use a tool like debugfs and were to open /dev/sda1 directly and to modify it's contents. We might hope that this would also be logged, but it isn't. The rules will check the major,minor of the device containing /dev/sda1. In other words the rule would match on the major/minor of the tmpfs mounted at /dev. I believe these rules should trigger on either device. The man page is devoid of useful information about the intended semantics. It only seems logical that if you want to know everything that happened on a major,minor that would include things that happened to the device itself... Signed-off-by: Eric Paris <eparis@redhat.com>
2012-01-17audit: dynamically allocate audit_names when not enough space is in the ↵Eric Paris
names array This patch does 2 things. First it reduces the number of audit_names allocated in every audit context from 20 to 5. 5 should be enough for all 'normal' syscalls (rename being the worst). Some syscalls can still touch more the 5 inodes such as mount. When rpc filesystem is mounted it will create inodes and those can exceed 5. To handle that problem this patch will dynamically allocate audit_names if it needs more than 5. This should decrease the typicall memory usage while still supporting all the possible kernel operations. Signed-off-by: Eric Paris <eparis@redhat.com>
2012-01-17audit: make filetype matching consistent with other filtersEric Paris
Every other filter that matches part of the inodes list collected by audit will match against any of the inodes on that list. The filetype matching however had a strange way of doing things. It allowed userspace to indicated if it should match on the first of the second name collected by the kernel. Name collection ordering seems like a kernel internal and making userspace rules get that right just seems like a bad idea. As it turns out the userspace audit writers had no idea it was doing this and thus never overloaded the value field. The kernel always checked the first name collected which for the tested rules was always correct. This patch just makes the filetype matching like the major, minor, inode, and LSM rules in that it will match against any of the names collected. It also changes the rule validation to reject the old unused rule types. Noone knew it was there. Noone used it. Why keep around the extra code? Signed-off-by: Eric Paris <eparis@redhat.com>

2011-04-27audit: acquire creds selectively to reduce atomic op overheadTony Jones
Commit c69e8d9c01db ("CRED: Use RCU to access another task's creds and to release a task's own creds") added calls to get_task_cred and put_cred in audit_filter_rules. Profiling with a large number of audit rules active on the exit chain shows that we are spending upto 48% in this routine for syscall intensive tests, most of which is in the atomic ops. 1. The code should be accessing tsk->cred rather than tsk->real_cred. 2. Since tsk is current (or tsk is being created by copy_process) access to tsk->cred without rcu read lock is possible. At the request of the audit maintainer, a new flag has been added to audit_filter_rules in order to make this explicit and guide future code.

2010-04-05audit: preface audit printk with auditEric Paris
There have been a number of reports of people seeing the message: "name_count maxed, losing inode data: dev=00:05, inode=3185" in dmesg. These usually lead to people reporting problems to the filesystem group who are in turn clueless what they mean. Eventually someone finds me and I explain what is going on and that these come from the audit system. The basics of the problem is that the audit subsystem never expects a single syscall to 'interact' (for some wish washy meaning of interact) with more than 20 inodes. But in fact some operations like loading kernel modules can cause changes to lots of inodes in debugfs. There are a couple real fixes being bandied about including removing the fixed compile time limit of 20 or not auditing changes in debugfs (or both) but neither are small and obvious so I am not sending them for immediate inclusion (I hope Al forwards a real solution next devel window). In the meantime this patch simply adds 'audit' to the beginning of the crap message so if a user sees it, they come blame me first and we can talk about what it means and make sure we understand all of the reasons it can happen and make sure this gets solved correctly in the long run.

2010-03-30include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo
implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.
