There is a race condition between V_ip_mrouter de-init
and ip_mforward handling. It might happen that mrouted
is cleaned up after V_ip_mrouter check and before
processing packet in ip_mforward.
Use epoch call aproach, similar to IPSec which also handles
such case.

There are two module declarations in the nfscl.ko module for "nfscl" and "nfs". Both of these declarations had MODULE_DEPEND() calls. This patch deletes the MODULE_DEPEND() calls for "nfs" to avoid confusion with respect to what modules this module is dependent upon. The patch also adds comments explaining why there are two module declarations within the module. Reviewed by: kib Differential Revision: https://reviews.freebsd.org/D30102cgit |

rtld preserves its current error message around calls to user init/fini lists, to not override original error with potential secondary errors caused by user code recursing into rtld. After 4d9128da54f8f8e2a29190, the preservation of the string itself is not enough, the 'seen' indicator must be preserved as well. Otherwise, since new code does not clear string (it cannot), call to _rtld_error() from errmsg_restore() revived whatever message was consumed last. Change errmsg_save() to return structure recording both 'seen' indicator and the message, if any. PR: 255698 Reported by: Eugene M.
