+
+ Disable tests where fs perms are incorrect
+
+ Some tests have strict requirements on the filesystem permissions
+ for certain files and directories. This adds a regress/check-perm
+ tool that copies the relevant logic from sshd to exactly test
+ the paths in question. This lets us skip tests when the local
+ filesystem doesn't conform to our expectations rather than
+ continuing and failing the test run.

+
+ Make Solaris privs code build on older systems.
+
+ Not all systems with Solaris privs have priv_basicset so factor that
+ out and provide backward compatibility code. Similarly, not all have
+ PRIV_NET_ACCESS so wrap that in #ifdef. Based on code from
+ alex at cooperi.net and djm@ with help from carson at taltos.org and
+ wieland at purdue.edu.

+
+ refactor activation of rekeying
+
+ This makes automatic rekeying internal to the packet code (previously
+ the server and client loops needed to assist). In doing to it makes
+ application of rekey limits more accurate by accounting for packets
+ about to be sent as well as packets queued during rekeying events
+ themselves.

+ Aleksander Adamowski in bz#2521; ok markus@

- - (dtucker) [configure.ac] On Cygwin the getopt variables (like optargs,
- optind) are defined in getopt.h already. Unfortunately they are defined as
- "declspec(dllimport)" for historical reasons, because the GNU linker didn't
- allow auto-import on PE/COFF targets way back when. The problem is the
- dllexport attributes collide with the definitions in the various source
- files in OpenSSH, which obviousy define the variables without
- declspec(dllimport). The least intrusive way to get rid of these warnings
- is to disable warnings for GCC compiler attributes when building on Cygwin.
