With commit d6ddef9e(IPv6: Fix not join all-router mcast group when forwarding set.) I check 'dev' after it's dereference that leads to a Smatch complaint: net/ipv6/addrconf.c:438 ipv6_add_dev() warn: variable dereferenced before check 'dev' (see line 432) net/ipv6/addrconf.c 431 /* protected by rtnl_lock */ 432 rcu_assign_pointer(dev->ip6_ptr, ndev); ^^^^^^^^^^^^ Old dereference. 433 434 /* Join all-node multicast group */ 435 ipv6_dev_mc_inc(dev, &in6addr_linklocal_allnodes); 436 437 /* Join all-router multicast group if forwarding is set */ 438 if (ndev->cnf.forwarding && dev && (dev->flags & IFF_MULTICAST)) ^^^ Remove the check to avoid the complaint as 'dev' can't be NULL.

Kill faulty checks on flow-off leading to connection drop at race conditions. caif_socket checks for flow-on before transmitting and goes to sleep or return -EAGAIN upon flow stop. Remove faulty subsequent checks on flow-off leading to connection drop. Also fix memory leaks on some of the errors paths.

Commit f0fbf0ab ("x86: integrate delay functions") converted delay_tsc() into a random delay generator for 64 bit. The reason is that it merged the mostly identical versions of delay_32.c and delay_64.c. Though the subtle difference of the result was: static void delay_tsc(unsigned long loops) { - unsigned bclock, now; + unsigned long bclock, now; Now the function uses rdtscl() which returns the lower 32bit of the TSC. On 32bit that's not problematic as unsigned long is 32bit. On 64 bit this fails when the lower 32bit are close to wrap around when bclock is read, because the following check if ((now - bclock) >= loops) break; evaluated to true on 64bit for e.g. bclock = 0xffffffff and now = 0 because the unsigned long (now - bclock) of these values results in 0xffffffff00000001 which is definitely larger than the loops value. That explains Tvortkos observation: "Because I am seeing udelay(500) (_occasionally_) being short, and that by delaying for some duration between 0us (yep) and 491us." Make those variables explicitely u32 again, so this works for both 32 and 64 bit.

in iwlwifi: move setting up fw parameters Meenakshi moved code up to configure the transport layer, but this code read the sku before it was set (from the EEPROM). This killed P2P. Only the ucode_flags are needed to configure the transport layer, not the sku which _must_ be set after the EEPROM is read. We need to reconfigure the transport in case the EEPROM disabled PAN support. This is not the nicest thing to do, but we have no choice. Document that we are allowed to configure the transport several times before start_fw, but not after.
