Subject: Calling mnl_socket_sendto caused error of netlink attribute type 1 has an invalid length
Date: Mon, 30 Dec 2019 19:50:56 +1100 [thread overview]
Message-ID: <CAA=hcWTJWi3wcWez-adCE4NvzVbbeWSpwSNCz9cebnSDnGPtcQ@mail.gmail.com> (raw)
Hi,
I have following error of attribute type 1 has an invalid length when
calling following mnl_socket_sendto(channel->mnlSocket, nlh,
nlh->nlmsg_len), I cannot see what was wrong about it, the
nlh->nlmsg_len = 40 which is from libnml, is that wrong? Please advise
how to fix it.
[ 3240.939609] netlink: 'wifi_signal': attribute type 1 has an invalid
length. I have a WiFi function using nml API:
typedef struct {
struct mnl_socket *mnlSocket;
char buf[BUFFER_SIZE];
uint16_t channelId;
uint32_t interfaceIndex;
uint32_t sequence;
void *context;
} __attribute__ ((packed)) Netlink80211Channel_t;
void WiFiScan::Send80211Message(struct nlmsghdr *nlh,
Netlink80211Channel_t *channel) {
if (mnl_socket_sendto(channel->mnlSocket, nlh, nlh->nlmsg_len) < 0) {
std::cout << "Failed to send socket" << std::endl;
}
}
Thank you.
