#2445 Race condition while invalidating memory cache in client code
Closed: Fixed None Opened 9 years ago by lslebodn.

If caches is invalidated with command sss_cache -U (-G or -E) then client code will need to reinitialize fast memory cache. Thread safe initialisation was fixed in ticket #2380. The 1st thread find out then memory cache should be reinitialized; therefore it fast memory cached is unmapped and context destroyed. In the same time, 2nd thread tried to check header of memory cache whether it was initialized and valid. As a result of previously unmapped memory 2nd thread access memory out of bound. (SEGFAULT)
