Subject: [PATCH 0/3] Fixes for usercopy
Date: Sun, 12 Jun 2022 22:32:24 +0100 [thread overview]
Message-ID: <20220612213227.3881769-1-willy@infradead.org> (raw)
Kees, I'm hoping you'll take these through your tree. I think they're
all reasonable fixes to go into 5.19. The first one is essential;
it fixes two different bugs that people have hit.
Matthew Wilcox (Oracle) (3):
usercopy: Handle vm_map_ram() areas
usercopy: Cast pointer to an integer once
usercopy: Make usercopy resilient against ridiculously large copies
