After commit 2b85a34e (net: No more expensive sock_hold()/sock_put() on each tx) we do not take any more references on sk->sk_refcnt on outgoing packets. I forgot to delete two __sock_put() from ip_push_pending_frames() and ip6_push_pending_frames().

Some sockets use SLAB_DESTROY_BY_RCU, and our RCU code correctness depends on sk->sk_nulls_node.next being always valid. A NULL value is not allowed as it might fault a lockless reader. Current sk_prot_alloc() implementation doesnt respect this hypothesis, calling kmem_cache_alloc() with __GFP_ZERO. Just call memset() around the forbidden field.

Commit c3a8c5b6 ("cxgb3: move away from LLTX") exposed a bug in how cxgb3 looks up the netdev_queue it stashes away in a qset during initialization. For multiport devices, the TX queue index it uses is offset by the first_qset index of each port. This leads to a crash once LLTX is removed, since hard_start_xmit is called with one TX queue lock held, while the TX reclaim timer task grabs a different (wrong) TX queue lock when it frees skbs. Fix this by removing the first_qset offset used to look up the TX queue passed into t3_sge_alloc_qset() from setup_sge_qsets().

Fix coexistence of Fiber Channel over Ethernet (FCoE) and Flow Director (FDIR) in 82599 and remove the disabling of FDIR when FCoE is enabled. Currently, FDIR is turned off when FCoE is enabled under the assumption that FCoE is always enabled with DCB being turned on. However, FDIR does not have to be turned off all the time when FCoE is enabled since FCoE can be enabled without DCB being turned on, e.g., use link pause only. This patch makes sure that when DCB is turned on or off, FDIR is turned on or off correspondingly; and when FCoE is enabled, it does not disable FDIR, rather, it will have FDIR set up properly so FCoE and FDIR can coexist regardless of DCB being on or off.

Adding memory barrier after the poll_wait function, paired with receive callbacks. Adding fuctions sock_poll_wait and sk_has_sleeper to wrap the memory barrier. Without the memory barrier, following race can happen. The race fires, when following code paths meet, and the tp->rcv_nxt and __add_wait_queue updates stay in CPU caches. CPU1 CPU2 sys_select receive packet ... ... __add_wait_queue update tp->rcv_nxt ... ... tp->rcv_nxt check sock_def_readable ... { schedule ... if (sk->sk_sleep && waitqueue_active(sk->sk_sleep)) wake_up_interruptible(sk->sk_sleep) ... } If there was no cache the code would work ok, since the wait_queue and rcv_nxt are opposit to each other. Meaning that once tp->rcv_nxt is updated by CPU2, the CPU1 either already passed the tp->rcv_nxt check and sleeps, or will get the new value for tp->rcv_nxt and will return with new data mask. In both cases the process (CPU1) is being added to the wait queue, so the waitqueue_active (CPU2) call cannot miss and will wake up CPU1. The bad case is when the __add_wait_queue changes done by CPU1 stay in its cache, and so does the tp->rcv_nxt update on CPU2 side. The CPU1 will then endup calling schedule and sleep forever if there are no more data on the socket. Calls to poll_wait in following modules were ommited: net/bluetooth/af_bluetooth.c net/irda/af_irda.c net/irda/irnet/irnet_ppp.c net/mac80211/rc80211_pid_debugfs.c net/phonet/socket.c net/rds/af_rds.c net/rfkill/core.c net/sunrpc/cache.c net/sunrpc/rpc_pipe.c net/tipc/socket.c Signed-off-by: NJiri Olsa <jolsa@redhat.com> Signed-off-by: NEric Dumazet <eric.dumazet@gmail.com> Signed-off-by: NDavid S.

Using early netconsole and gianfar driver this error pops up: netconsole: timeout waiting for carrier It appears that net/core/netpoll.c:netpoll_setup() is using cond_resched() in a loop waiting for a carrier. The thing is that cond_resched() is a no-op when system_state != SYSTEM_RUNNING, and so drivers/net/phy/phy.c's state_queue is never scheduled, therefore link detection doesn't work. I belive that the main problem is in cond_resched()[1], but despite how the cond_resched() story ends, it might be a good idea to call msleep(1) instead of cond_resched(), as suggested by Andrew Morton.

In the mainline kernel, p54usb will fail because the TX queue length can become < 0. This problem has been reported as Bugzilla #13725. The failure is expressed by the following message in the logs: WARNING: at net/mac80211/tx.c:1325 ieee80211_tx+0x23c/0x298 [mac80211]() Hardware name: HP Pavilion dv2700 Notebook PC tx refused but queue active This problem has been recently observed in the wireless-testing tree, where a full solution is being tested.

Atheros top level menu needs a "depends WLAN_80211" to properly indent within menuconfig and xconfig interfaces. This is purely a visual issue but it effects all subsequent drivers. The issue is the top level menu does not include a dependency on WLAN_80211 so within the tree structure, Atheros is at the same level as WLAN_80211 but when WLAN_80211 collapsed, the menu disappears along with all subsequent drives, so it is really a subordinate.

When we reclaim the tx desc, we always assume that the last desc is a holding desc, which is not true, and skip it. If the tx queue is drained during channel change, internal reset and etc, the last descriptor may not be the holding descriptor and we fail to reclaim them. This results in the following two issues. 1. Tx stuck - We drop all the frames coming from upper layer due to shortage in tx desc. 2. Crash - If we fail to reclaim a tx descriptor, we miss to update the tx BA window with the seq number of the frame associated to that desc, which, at some point, result in the following crash due to an assert failure in ath_tx_addto_baw(). This patch fixes these two issues. kernel BUG at ../drivers/net/wireless/ath/ath9k/xmit.c:180!

Fix condition in which radio LED did not initialize correctly, and remove 4 compilation warnings. After the recent changes in rfkill, the radio LED used by b43/b43legacy did not always initialize correctly.

fec: fix definition of 5272 version of FEC_X_DES_ACTIVE register The ColdFire 5272 FEC driver has a different register address map than other users of the FEC driver. And its definition of the FEC_X_DES_ACTIVE register is incorrect, it should be 0x14. The fec interface cannot transmit data with the old value.

The call resource_size(res) returns res->end - res->start + 1 and thus the second change is semantics-preserving. res_size is then used as the second argument of a call to request_mem_region, and the memory allocated by this call appears to be the same as what is released in the two calls to release_mem_region. So the size argument for those calls should be resource_size(size) as well. Alternatively, in the second call to release_mem_region, the second argument could be res_size, as that variable has already been initialized at the point of this call. The problem was found using the following semantic patch: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ struct resource *res; @@ - (res->end - res->start) + 1 + resource_size(res) @@ struct resource *res; @@ - res->end - res->start + BAD(resource_size(res)) // </smpl> Signed-off-by: NJulia Lawall <julia@diku.dk> Signed-off-by: NDavid S.
