2014-05-06nick kvfree() from apparmorAl Viro1-14/+0
too many places open-code it Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2013-08-14apparmor: remove minimum size check for vmalloc()Tetsuo Handa1-5/+0
This is a follow-up to commit b5b3ee6c "apparmor: no need to delay vfree()". Since vmalloc() will do "size = PAGE_ALIGN(size);", we don't need to check for "size >= sizeof(struct work_struct)".

2013-05-12apparmor: no need to delay vfree()Al Viro1-21/+3
vfree() can be called from interrupt contexts now Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Acked-by: John Johansen <john.johansen@canonical.com> Signed-off-by: James Morris <james.l.morris@oracle.com>
2013-04-28apparmor: fix fully qualified name parsingJohn Johansen1-2/+4
currently apparmor name parsing is only correctly handling :<NS>:<profile> but :<NS>://<profile> is also a valid form and what is exported to userspace. Signed-off-by: John Johansen <john.johansen@canonical.com>

2012-04-09LSM: do not initialize common_audit_data to 0Eric Paris1-1/+1
It isn't needed. If you don't set the type of the data associated with that type it is a pretty obvious programming bug. So why waste the cycles? Signed-off-by: Eric Paris <eparis@redhat.com>
2012-04-09LSM: remove the COMMON_AUDIT_DATA_INIT type expansionEric Paris1-1/+1
Just open code it so grep on the source code works better. Signed-off-by: Eric Paris <eparis@redhat.com>
2012-04-03LSM: shrink sizeof LSM specific portion of common_audit_dataEric Paris1-1/+3
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.

2011-06-22net: remove mm.h inclusion from netdevice.hAlexey Dobriyan1-0/+1
Remove linux/mm.h inclusion from netdevice.h -- it's unused (I've checked manually). To prevent mm.h inclusion via other channels also extract "enum dma_data_direction" definition into separate header. This tiny piece is what gluing netdevice.h with mm.h via "netdevice.h => dmaengine.h => dma-mapping.h => scatterlist.h => mm.h". Removal of mm.h from scatterlist.h was tried and was found not feasible on most archs, so the link was cutoff earlier. Hope people are OK with tiny include file. Note, that mm_types.h is still dragged in, but it is a separate story. Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2010-09-08AppArmor: Fix splitting an fqname into separate namespace and profile namesJohn Johansen1-1/+1
As per Dan Carpenter <error27@gmail.com> If we have a ns name without a following profile then in the original code it did "*ns_name = &name[1];". "name" is NULL so "*ns_name" is 0x1. That isn't useful and could cause an oops when this function is called from aa_remove_profiles(). Beyond this the assignment of the namespace name was wrong in the case where the profile name was provided as it was being set to &name[1] after name = skip_spaces(split + 1); Move the ns_name assignment before updating name for the split and also add skip_spaces, making the interface more robust.
