Chao Yu ([email protected]) changed: What |Removed |Added ---------------------------------------------------------------------------- Status|NEW |ASSIGNED CC| |[email protected] --- Comment #1 from Chao Yu ([email protected]) --- I didn't see many filesystems are using kzfree(), instead, there are many callers come from crypto module, I guess they use the buffer to store ciphertext or crypto key temporarily, so, before freeing those buffer it will be better to clean the data in buffer to avoid confidential data leak. For f2fs, I think there is no such demand, and we just missed to change kzfree to kvfree in below commit: 5222595d093e ("f2fs: use kvmalloc, if kmalloc is failed") -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ Linux-f2fs-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/linux-f2fs-devel
