[strongSwan-dev] charon deadlock involving three threads

[Tobias Brunner]

Hi Thomas,

I checked in some patches which fix this particular deadlock.  The first
one [1] actually fixes a possible segmentation fault during shutdown in
4.6.1.  Patch [2] adds some atomic compare and swap wrappers to fix a
TOCTOU problem in trap_manager_t.  Finally, patch [3] fixes the deadlock
by not holding the read lock while waiting for the IKE_SA.

Regards,
Tobias
