258fa9d4f9 Add debug support to sudo_intercept.so 2021-08-09 15:50:25 -06:00

9c3df47da9 Move preload_dso() to its own file and rename to sudo_preload_dso(). 
It now takes an intercept fd as an optional argument instead of a
list of extra variables to add.  This lets us check whether it is
already set to the expected value (and add it if not).
sudo_intercept.so now uses sudo_preload_dso() to make sure that
LD_PRELOAD and SUDO_INTERCEPT_FD are set properly before executing.

Uses protobuf to talk to main sudo process over a socketpair.
