2012-07-18cipso: don't follow a NULL pointer when setsockopt() is calledPaul Moore
As reported by Alan Cox, and verified by Lin Ming, when a user attempts to add a CIPSO option to a socket using the CIPSO_V4_TAG_LOCAL tag the kernel dies a terrible death when it attempts to follow a NULL pointer (the skb argument to cipso_v4_validate() is NULL when called via the setsockopt() syscall). This patch fixes this by first checking to ensure that the skb is non-NULL before using it to find the incoming network interface. In the unlikely case where the skb is NULL and the user attempts to add a CIPSO option with the _TAG_LOCAL tag we return an error as this is not something we want to allow. A simple reproducer, kindly supplied by Lin Ming, although you must have the CIPSO DOI #3 configure on the system first or you will be caught early in cipso_v4_validate(): #include <sys/types.h> #include <sys/socket.h> #include <linux/ip.h> #include <linux/in.h> #include <string.h> struct local_tag { char type; char length; char info[4]; }; struct cipso { char type; char length; char doi[4]; struct local_tag local; }; int main(int argc, char **argv) { int sockfd; struct cipso cipso = { .type = IPOPT_CIPSO, .length = sizeof(struct cipso), .local = { .type = 128, .length = sizeof(struct local_tag), }, }; memset(cipso.doi, 0, 4); cipso.doi[3] = 3; sockfd = socket(AF_INET, SOCK_DGRAM, 0); #define SOL_IP 0 setsockopt(sockfd, SOL_IP, IP_OPTIONS, &cipso, sizeof(struct cipso)); return 0; } CC: Lin Ming <mlin@ss.pku.edu.cn> Reported-by: Alan Cox <alan@lxorguk.ukuu.org.uk> Signed-off-by: Paul Moore <pmoore@redhat.com> Signed-off-by: David S.

2012-07-18mac80211: flush stations before stop beaconingEliad Peller
When AP interface is going down, the stations are flushed (in ieee80211_do_stop()) only after the beaconing was stopped. However, drivers might rely on stations being removed before the beaconing was stopped, in order to clean up properly. Fix it by flushing the stations on ap stop.

2012-07-18wlcore: wait for command completion event when sending CMD_ROLE_STOPLuciano Coelho
We need to wait for the command completion event when we send the CMD_ROLE_STOP event otherwise we may try to send CMD_ROLE_START too soon and get out-of-sync with the firmware. In some cases, the firmware may not send the event, so we wait for the event or for the timeout, whichever comes first. This patch is based on an earlier version by Eliad.
