fstat(1) patch: display I/O stats in bytes

I rely on the `-s' flag to fstat(1) for a lot of dev work. It's a bit of a pain sometimes that the I/O counter returned has only KByte granularity. I've been modifying fstat.c as needed. This time I considered whether sending a patch would be acceptable. It simply adds a `-b' flag that does the

Does "no wxallowed" FS always disable wxneeded apps?

Hello, It seems that app with OPENBSD_WXNEED header can't be launhed on fs, mounted with out of wxallowed. Call (I assume execve) returns "Permission denied" for such binaries. Is it correct? So, to use WX pages I need: 1) link it with -z wxneeded (I will get "Not supported" from mmap otherwise)

const for BIO_new, BIO_set and BIO_{f,s}_*

sigpause visibility

Hi, The POSIX test suite reveals that sigpause(int sigmask) from 4.2 BSD takes a signal mask as argument while POSIX sigpause(int sig) expects a single signal. As the semantics are different, we should not expose our sigpause(3) to POSIX sources. ok? bluhm Index: include/signal.h =

route(8): stop debugging route monitor

The -d flag should be a no-op in monitor mode since it does not modify the routing table. However, if -d is provided route monitor lists all interfaces and their associated addresses and exits. This is confusing, unexpected and no longer needed (if ever). Make -d a proper no-op for route monitor

Push the netlock down in in_control()

With mpi's encouragement and guidance, here's a diff that reduces the scope of the NET_LOCK() a bit. in_control() is the only caller of mrt_ioctl() and the latter is a simple function only requiring a read lock. There are only a handful callers of in_ioctl(). The two switches create relatively ta

5GHz AP RSSI measurement problem

I've ran into what seems to be a fairly modern dual-band AP (issued by a French ISP). This AP camps on channel 112. This channel requires radar detection which may explain the behaviour described below. The AP sends 5GHz beacons with a ridicously low RSSI while no client is connected, and OpenBSD
