tcp: identify cryptic messages as TCP seq # bugs
Attempt to make cryptic TCP seq number error messages clearer by (1) identifying the source of the message as "TCP", (2) identifying the errors as "seq # bug", and (3) grouping the field identifiers and values by separating them with commas. E.g., the following message is changed from: recvmsg bug 2: copied 73BCB6CD seq 70F17CBE rcvnxt 73BCB9AA fl 0 WARNING: CPU: 2 PID: 1501 at /linux/net/ipv4/tcp.c:1881 tcp_recvmsg+0x649/0xb90 to: TCP recvmsg seq # bug 2: copied 73BCB6CD, seq 70F17CBE, rcvnxt 73BCB9AA, fl 0 WARNING: CPU: 2 PID: 1501 at /linux/net/ipv4/tcp.c:2011 tcp_recvmsg+0x694/0xba0 Suggested-by: 積丹尼 Dan Jacobson <jidanni@jidanni.org> Signed-off-by: Randy Dunlap <rdunlap@infradead.org> Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.
