Interrupt race in NET_LOCK/NET_UNLOCK

NET_LOCK() should raise IPL before acquiring the lock, and NET_UNLOCK() should restore the level after releasing the lock. Otherwise, lock recursion can occur, most likely right after the splx(). An example: nd6_slowtimo <- NET_LOCK() timeout_run softclock softintr_dispatch dosoftint interrupt

ld.so: -fno-builtin?

Building ld.so with clang on amd64 fails with undefined references to memset and memcpy. That is odd, since neither function appears in the source. Apparently clang optimizes the _dl_memset and _dl_bcopy functions into calls to memset and memcpy, respectively. I tentatively propose to add

Not sure if these have been reported. With a kernel freshly built from sources this morning, my dmesg is full of these: splassert: sorwakeup: want 1 have 0 Starting stack trace... sorwakeup() at sorwakeup+0x3c soisconnected() at soisconnected+0x6f unp_connect2() at unp_connect2+0x62
