Now that we can safely increase the avtab max buckets without triggering high order allocations and have a hash function that will make better use of the larger number of buckets, increase the max buckets to 2^16. Original: 101421 entries and 2048/2048 buckets used, longest chain length 374 With new hash function: 101421 entries and 2048/2048 buckets used, longest chain length 81 With increased max buckets: 101421 entries and 31078/32768 buckets used, longest chain length 12 Signed-off-by: Stephen Smalley <sds@xxxxxxxxxxxxx> --- security/selinux/ss/avtab.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/security/selinux/ss/avtab.h b/security/selinux/ss/avtab.h index 6d794a2..adb451c 100644 --- a/security/selinux/ss/avtab.h +++ b/security/selinux/ss/avtab.h @@ -86,7 +86,7 @@ struct avtab_node *avtab_search_node_next(struct avtab_node *node, int specified void avtab_cache_init(void); void avtab_cache_destroy(void); -#define MAX_AVTAB_HASH_BITS 11 +#define MAX_AVTAB_HASH_BITS 16 #define MAX_AVTAB_HASH_BUCKETS (1 << MAX_AVTAB_HASH_BITS) #endif /* _SS_AVTAB_H_ */ -- 1.9.3 _______________________________________________ Selinux mailing list Selinux@xxxxxxxxxxxxx To unsubscribe, send email to Selinux-leave@xxxxxxxxxxxxx.
