[PATCH] mm: Change count_mm_mlocked_page_nr return type

From: swkhack In 64-bit machine,the value of "vma->vm_end - vma->vm_start" maybe negative in 32bit int and the "count >> PAGE_SHIFT"'s result will be wrong.So change the local variable and return value to unsigned long will fix the problem. Signed-off-by: swkhack --- mm/mlock.c | 4 ++-- 1 fil

[PATCH] lkdtm: fix potential use after free

From: swkhack The function lkdtm_WRITE_AFTER_FREE calls kfree(base) to free the memory of base. However, following kfree(base), it write the memory which base point to via base[offset] = 0x0abcdef0. This may result in a use-after-free bug. This patch moves kfree(base) after the write. Signed-of

[PATCH] time: fix a assignment error in ntp module

From: swkhack It is meanless to check a 64bit(txc->constant) value is postive when the value has to be assigned to a 32 bit variable(*time_tai). So I make a temp type conversion before the compare. Signed-off-by: swkhack --- kernel/time/ntp.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion
