[RFC PATCH 0/1][RESEND] Fix KASAN: slab-out-of-bounds Read in sk_psock_get

From: Khalid Masum
Date: Wed Jul 13 2022 - 14:14:45 EST


Using size of sk_psock as the size for kcm_psock_cache size no longer
reproduces the issue. There might be a better way to solve this issue
though so I would like to ask for feedback.

The patch was sent to the wrong mailing list so resending it. Please
ignore the previous one.
