Description Jiffin 2015-07-01 05:47:20 EDT

+++ This bug was initially created as a clone of Bug #1238145 +++

Description of problem:

fsal_acl_t entries which represents inherit acl may not contains all the required entries, but fsal_acl_2_posix_acl() api include accordingly.For that we may need to allocate acl_t structure with more than the required entries.

Comment 4 Jiffin 2015-07-02 04:31:09 EDT

This is fixed in https://review.gerrithub.io/#/c/237728/

Comment 6 Saurabh 2015-07-14 06:56:21 EDT

As per discussion with developer, the memory corruption could have happened in case of inherit acl setfacl and getfacl, but post fix I can see that setting and getting acls with inherit flags works fine.
