[Linux-stable-mirror] [PATCH v2 01/10] staging: ccree: fix leak of import() after init()

by Gilad Ben-Yossef

crypto_ahash_import() may be called either after crypto_ahash_init() or without such call. Right now we always internally call init() as part of import(), thus leaking memory and mappings if the user has already called init() herself. Fix this by only calling init() internally if the state is not already initialized.

So the switching-in task must move forward its start time snapshot to the current time in order to later compute the delta spent in system mode. This is what we do for the normal cputime by initializing the starttime field to the value of the previous task's starttime which got freshly updated. But we are missing the update of the scaled cputime start time. As a result we may be accounting too much scaled cputime later. Fix this by initializing the scaled cputime the same way we do for normal cputime.

This is more than suboptimal since it partially doesn't work. For the fake NUMA case topology information is still considered and scheduling domains will be created based on this. To fix this and to simplify the code get rid of the extra variable and implement the "topology=off" case like it is done for other features.
