Hi!
This bug pertains to the manpage as visible on man7.org right
now.
The socket(7) man page has this paragraph:
SO_RXQ_OVFL (since Linux 2.6.33)
Indicates that an unsigned 32-bit value ancillary message (cmsg) should be attached to
received skbs indicating the number of packets dropped by the socket between the last
received packet and this received packet.
The second half is wrong: the counter (internally,
SOCK_SKB_CB(skb)->dropcount is *not* reset after every packet.
That is, it is a proper counter, not a gauge, in monitoring
parlance.
A better version of that paragraph:
SO_RXQ_OVFL (since Linux 2.6.33)
Indicates that an unsigned 32-bit value ancillary message (cmsg) should be attached to
received skbs indicating the number of packets dropped by the socket since its
creation.
Regards,
Tobias
