ozaki-r 75ffcec5e7 Avoid a race condition between SA (sav) manipulations 
An sav can be removed from belonging list(s) twice resulting in an assertion
failure of pslist.  It can occur if the following two operations interleave:
(i) a deletion or a update of an SA via the API, and
(ii) a state change (key_sa_chgstate) of the same SA by the timer.
Note that even (ii) removes an sav once from its list(s) on a update.

The cause of the race condition is that the two operations are not serialized
and (i) doesn't get and remove an sav from belonging list(s) atomically.  So
(ii) can be inserted between an acquisition and a removal of (i).

Avoid the race condition by making (i) atomic.

NetBSD

NetBSD is a free, fast, secure, and highly portable Unix-like Open Source operating system. It is available for a wide range of platforms, from large-scale servers and powerful desktop systems to handheld and embedded devices.

Building

You can cross-build NetBSD from most UNIX-like operating systems. To build for amd64 (x86_64), in the src directory:

./build.sh -U -u -j4 -m amd64 -O ~/obj release

Additional build information available in the BUILDING file.

Binaries

Testing

On a running NetBSD system:

cd /usr/tests; atf-run | atf-report

Troubleshooting

Latest sources

To fetch the main CVS repository:

cvs -d anoncvs@anoncvs.NetBSD.org:/cvsroot checkout -P src

To work in the Git mirror, which is updated every few hours from CVS:

git clone https://github.com/NetBSD/src.git
