2012-04-03lsm_audit: don't specify the audit pre/post callbacks in 'struct common_audit_data'Linus Torvalds1-3/+1
It just bloats the audit data structure for no good reason, since the only time those fields are filled are just before calling the common_lsm_audit() function, which is also the only user of those fields. So just make them be the arguments to common_lsm_audit(), rather than bloating that structure that is passed around everywhere, and is initialized in hot paths.

2012-04-03LSM: shrink the common_audit_data data unionEric Paris1-42/+63
After shrinking the common_audit_data stack usage for private LSM data I'm not going to shrink the data union. To do this I'm going to move anything larger than 2 void * ptrs to it's own structure and require it to be declared separately on the calling stack. Thus hot paths which don't need more than a couple pointer don't have to declare space to hold large unneeded structures. I could get this down to one void * by dealing with the key struct and the struct path. We'll see if that is helpful after taking care of networking.

2012-04-03LSM: shrink sizeof LSM specific portion of common_audit_dataEric Paris3-17/+104
Linus found that the gigantic size of the common audit data caused a big perf hit on something as simple as running stat() in a loop. This patch requires LSMs to declare the LSM specific portion separately rather than doing it in a union. Thus each LSM can be responsible for shrinking their portion and don't have to pay a penalty just because other LSMs have a bigger space requirement.

2012-03-31selinux: inline avc_audit() and avc_has_perm_noaudit() into callerLinus Torvalds1-2/+2
Now that all the slow-path code is gone from these functions, we can inline them into the main caller - avc_has_perm_flags(). Now the compiler can see that 'avc' is allocated on the stack for this case, which helps register pressure a bit. It also actually shrinks the total stack frame, because the stack frame that avc_has_perm_flags() always needed (for that 'avc' allocation) is now sufficient for the inlined functions too. Inlining isn't bad - but mindless inlining of cold code (see the previous commit) is. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2012-03-31selinux: don't inline slow-path code into avc_has_perm_noaudit()Linus Torvalds1-14/+38
The selinux AVC paths remain some of the hottest (and deepest) codepaths at filename lookup time, and we make it worse by having the slow path cases take up I$ and stack space even when they don't trigger. Gcc tends to always want to inline functions that are just called once - never mind that this might make for slower and worse code in the caller. So this tries to improve on it a bit by making the slow-path cases explicitly separate functions that are marked noinline, causing gcc to at least no longer allocate stack space for them unless they are actually called. It also seems to help register allocation a tiny bit, since gcc now doesn't take the slow case code into account. Uninlining the slow path may also allow us to inline the remaining hot path into the one caller that actually matters: avc_has_perm_flags(). I'll have to look at that separately, but both avc_audit() and avc_has_perm_noaudit() are now small and lean enough that inlining them may make sense.

2012-03-22security: optimize avc_audit() common pathLinus Torvalds1-29/+41
avc_audit() did a lot of jumping around and had a big stack frame, all for the uncommon case. Split up the uncommon case (which we really can't make go fast anyway) into its own slow function, and mark the conditional branches appropriately for the common likely case. This causes avc_audit() to no longer show up as one of the hottest functions on the branch profiles (the new "perf -b" thing), and makes the cycle profiles look really nice and dense too. The whole audit path is still annoyingly very much one of the biggest costs of name lookup, so these things are worth optimizing for. I wish we could just tell people to turn it off, but realistically we do need it: we just need to make sure that the overhead of the necessary evil is as low as possible.

2012-02-19Replace the fd_sets in struct fdtable with an array of unsigned longsDavid Howells1-1/+1
Replace the fd_sets in struct fdtable with an array of unsigned longs and then use the standard non-atomic bit operations rather than the FD_* macros. This: (1) Removes the abuses of struct fd_set: (a) Since we don't want to allocate a full fd_set the vast majority of the time, we actually, in effect, just allocate a just-big-enough array of unsigned longs and cast it to an fd_set type - so why bother with the fd_set at all? (b) Some places outside of the core fdtable handling code (such as SELinux) want to look inside the array of unsigned longs hidden inside the fd_set struct for more efficient iteration over the entire set. (2) Eliminates the use of FD_*() macros in the kernel completely. (3) Permits the __FD_*() macros to be deleted entirely where not exposed to userspace.

2012-01-05security: remove the security_netlink_recv hook as it is equivalent to capable()Eric Paris1-19/+0

2012-01-05ptrace: do not audit capability check when outputing /proc/pid/statEric Paris1-1/+1
Reading /proc/pid/stat of another process checks if one has ptrace permissions on that process. If one does have permissions it outputs some data about the process which might have security and attack implications. If the current task does not have ptrace permissions the read still works, but those fields are filled with inocuous (0) values. Since this check and a subsequent denial is not a violation of the security policy we should not audit such denials. This can be quite useful to removing ptrace broadly across a system without flooding the logs when ps is run or something which harmlessly walks proc.

2012-01-05capabilities: remove the task from capable LSM hook entirelyEric Paris1-13/+10
The capabilities framework is based around credentials, not necessarily the current task. Yet we still passed the current task down into LSMs from the security_capable() LSM hook as if it was a meaningful portion of the security decision. This patch removes the 'generic' passing of current and instead forces individual LSMs to use current explicitly if they think it is appropriate. In our case those LSMs are SELinux and AppArmor. I believe the AppArmor use of current is incorrect, but that is wholely unrelated to this patch. This patch does not change what AppArmor does, it just makes it clear in the AppArmor code that it is doing it. The SELinux code still uses current in it's audit message, which may also be wrong and needs further investigation. Again this is NOT a change, it may have always been wrong, this patch just makes it clear what is happening. Signed-off-by: Eric Paris <eparis@redhat.com>

2011-10-31selinux: Add export.h to files using EXPORT_SYMBOL/THIS_MODULEPaul Gortmaker2-0/+2
The pervasive, but implicit presence of <linux/module.h> meant that things like this file would happily compile as-is. But with the desire to phase out the module.h being included everywhere, point this file at export.h which will give it THIS_MODULE and the EXPORT_SYMBOL variants.
