From ca86cad7380e373fa17bc0ee8aff121380323e69 Mon Sep 17 00:00:00 2001 From: Richard Guy Briggs Date: Sat, 4 Feb 2017 13:10:38 -0500 Subject: audit: log module name on init_module This adds a new auxiliary record MODULE_INIT to the SYSCALL event. We get finit_module for free since it made most sense to hook this in to load_module(). https://github.com/linux-audit/audit-kernel/issues/7 https://github.com/linux-audit/audit-kernel/wiki/RFE-Module-Load-Record-Format Signed-off-by: Richard Guy Briggs Acked-by: Jessica Yu [PM: corrected links in the commit description] Signed-off-by: Paul Moore --- kernel/auditsc.c | 14 ++++++++++++++ 1 file changed, 14 insertions(+) (limited to 'kernel/auditsc.c') diff --git a/kernel/auditsc.c b/kernel/auditsc.c index bb5f504592c6..bde3aac4deed 100644 --- a/kernel/auditsc.c +++ b/kernel/auditsc.c @@ -1268,6 +1268,11 @@ static void show_special(struct audit_context *context, int *call_panic) case AUDIT_EXECVE: { audit_log_execve_info(context, &ab); break; } + case AUDIT_KERN_MODULE: + audit_log_format(ab, "name="); + audit_log_untrustedstring(ab, context->module.name); + kfree(context->module.name); + break; } audit_log_end(ab); } @@ -2368,6 +2373,15 @@ void __audit_mmap_fd(int fd, int flags) context->type = AUDIT_MMAP; } +void __audit_log_kern_module(char *name) +{ + struct audit_context *context = current->audit_context; + + context->module.name = kmalloc(strlen(name) + 1, GFP_KERNEL); + strcpy(context->module.name, name); + context->type = AUDIT_KERN_MODULE; +} + static void audit_log_task(struct audit_buffer *ab) { kuid_t auid, uid; -- cgit v1.2.3-55-g7522
