Miller" , io-uring@vger.kernel.org, John Fastabend , asml.silence@gmail.com Subject: [PATCH net 0/4] a few corrections for SOCK_SUPPORT_ZC Date: Thu, 27 Oct 2022 00:25:55 +0100 Message-Id: X-Mailer: git-send-email 2.38.0 MIME-Version: 1.0 Precedence: bulk List-ID: X-Mailing-List: io-uring@vger.kernel.org There are several places/cases that got overlooked in regards to SOCK_SUPPORT_ZC. We're lacking the flag for IPv6 UDP sockets and accepted TCP sockets. We also should clear the flag when someone tries to hijack a socket by replacing the ->sk_prot callbacks. Pavel Begunkov (3): udp: advertise ipv6 udp support for msghdr::ubuf_info net: remove SOCK_SUPPORT_ZC from sockmap net/ulp: remove SOCK_SUPPORT_ZC from tls sockets Stefan Metzmacher (1): net: also flag accepted sockets supporting msghdr originated zerocopy include/net/sock.h | 7 +++++++ net/ipv4/af_inet.c | 2 ++ net/ipv4/tcp_bpf.c | 4 ++-- net/ipv4/tcp_ulp.c | 3 +++ net/ipv4/udp_bpf.c | 4 ++-- net/ipv6/udp.c | 1 + net/unix/unix_bpf.c | 8 ++++---- 7 files changed, 21 insertions(+), 8 deletions(-)
