We can't rely on PPPOX_ZOMBIE to decide whether to clear po->pppoe_dev. PPPOX_ZOMBIE can be set by pppoe_disc_rcv() even when po->pppoe_dev is NULL. So we have no guarantee that (sk->sk_state & PPPOX_ZOMBIE) implies (po->pppoe_dev != NULL). Since we're releasing a PPPoE socket, we want to release the pppoe_dev if it exists and reset sk_state to PPPOX_DEAD, no matter the previous value of sk_state. So we can just check for po->pppoe_dev and avoid any assumption on sk->sk_state. Fixes: 2b018d57 ("pppoe: drop PPPOX_ZOMBIEs in pppoe_release") Signed-off-by:

Lendacky, Thomas authored
The code currently uses the lightweight dma_wmb barrier before updating the current descriptor count. Under heavy load, the Tx cleanup routine was seeing the updated current descriptor count before the updated descriptor information. As a result, the Tx descriptor was being cleaned up before it was used because it was not "owned" by the hardware yet, resulting in a Tx queue hang. Using the wmb barrier insures that the descriptor is updated before the descriptor counter preventing the Tx queue hang. For extra insurance, the Tx cleanup routine is changed to grab the current decriptor count on entry and uses that initial value in the processing loop rather than trying to chase the current value.

Hannes Frederic Sowa says: ==================== overflow-arith: begin to add support for overflow builtins functions I add a new header, linux/overflow-arith.h, as the central place to add overflow and wrap-around checking functions. The reason I am doing so is that it can make use of compiler supported builtin functions which can leverage hardware. As I need this for a fix in the ipv6 stack, which is also included in this series, I propose to add it sooner than later over Davem's net tree. This is also the reason why I start slowly with only the one function I need at this time. ==================== Signed-off-by: -

Raw sockets with hdrincl enabled can insert ipv6 extension headers right into the data stream. In case we need to fragment those packets, we reparse the options header to find the place where we can insert the fragment header. If the extension headers exceed the link's MTU we actually cannot make progress in such a case. Instead of ending up in broken arithmetic or rounding towards 0 and entering an endless loop in ip6_fragment, just prevent those cases by aborting early and signal -EMSGSIZE to user space.

The idea of the overflow-arith.h header is to collect overflow checking functions in one central place. If gcc compiler supports the __builtin_overflow_* builtins we use them because they might give better performance, otherwise the code falls back to normal overflow checking functions. The builtin_overflow functions are supported by gcc-5 and clang. The matter of supporting clang is to just provide a corresponding CC_HAVE_BUILTIN_OVERFLOW, because the specific overflow checking builtins don't differ between gcc and clang. I just provide overflow_usub function here as I intend this to get merged into net, more functions will definitely follow as they are needed. Signed-off-by:

If alpha is strictly reduced by alpha >> dctcp_shift_g and if alpha is less than 1 << dctcp_shift_g, then alpha may never reach zero. For example, given shift_g=4 and alpha=15, alpha >> dctcp_shift_g yields 0 and alpha remains 15. The effect isn't noticeable in this case below cwnd=137, but could gradually drive uncongested flows with leftover alpha down to cwnd=137. A larger dctcp_shift_g would have a greater effect. This change causes alpha=15 to drop to 0 instead of being decrementing by 1 as it would when alpha=16. However, it requires one less conditional to implement since it doesn't have to guard against subtracting 1 from 0U. A decay of 15 is not unreasonable since an equal or greater amount occurs at alpha >= 240. Signed-off-by:

In the vsock vmci_transport driver, sock_put wasn't safe to call in interrupt context, since that may call the vsock destructor which in turn calls several functions that should only be called from process context. This change defers the callling of these functions to a worker thread. All these functions were deallocation of resources related to the transport itself. Furthermore, an unused callback was removed to simplify the cleanup. Multiple customers have been hitting this issue when using VMware tools on vSphere 2015. Also added a version to the vmci transport module (starting from 1.0.2.0-k since up until now it appears that this module was sharing version with vsock that is currently at 1.0.1.0-k). Reviewed-by:

Currently, NETLINK_LIST_MEMBERSHIPS grabs the netlink table while copying the membership state to user-space. However, grabing the netlink table is effectively a write_lock_irq(), and as such we should not be triggering page-faults in the critical section. This can be easily reproduced by the following snippet: int s = socket(AF_NETLINK, SOCK_RAW, NETLINK_ROUTE); void *p = mmap(0, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANON, -1, 0); int r = getsockopt(s, 0x10e, 9, p, (void*)((char*)p + 4092)); This should work just fine, but currently triggers EFAULT and a possible WARN_ON below handle_mm_fault(). Fix this by reducing locking of NETLINK_LIST_MEMBERSHIPS to a read-side lock. The write-lock was overkill in the first place, and the read-lock allows page-faults just fine.

If userspace provides a ct action with no nested mark or label, then the storage for these fields is zeroed. Later when actions are requested, such zeroed fields are serialized even though userspace didn't originally specify them. Fix the behaviour by ensuring that no action is serialized in this case, and reject actions where userspace attempts to set these fields with mask=0.

In commit d999297c ("tipc: reduce locking scope during packet reception") we altered the packet retransmission function. Since then, when restransmitting packets, we create a clone of the original buffer using __pskb_copy(skb, MIN_H_SIZE), where MIN_H_SIZE is the size of the area we want to have copied, but also the smallest possible TIPC packet size. The value of MIN_H_SIZE is 24. Unfortunately, __pskb_copy() also has the effect that the headroom of the cloned buffer takes the size MIN_H_SIZE. This is too small for carrying the packet over the UDP tunnel bearer, which requires a minimum headroom of 28 bytes. A change to just use pskb_copy() lets the clone inherit the original headroom of 80 bytes, but also assumes that the copied data area is of at least that size, something that is not always the case. So that is not a viable solution. We now fix this by adding a check for sufficient headroom in the transmit function of udp_media.c, and expanding it when necessary.

The current code for message reassembly is erroneously assuming that the the first arriving fragment buffer always is linear, and then goes ahead resetting the fragment list of that buffer in anticipation of more arriving fragments. However, if the buffer already happens to be non-linear, we will inadvertently drop the already attached fragment list, and later on trig a BUG() in __pskb_pull_tail(). We see this happen when running fragmented TIPC multicast across UDP, something made possible since commit d0f91938 ("tipc: add ip/udp media type") We fix this by not resetting the fragment list when the buffer is non- linear, and by initiatlizing our private fragment list tail pointer to the tail of the existing fragment list.

The default fix broadcast window size is currently set to 20 packets. This is a very low value, set at a time when we were still testing on 10 Mb/s hubs, and a change to it is long overdue. Commit 7845989c ("net: tipc: fix stall during bclink wakeup procedure") revealed a problem with this low value. For messages of importance LOW, the backlog queue limit will be calculated to 30 packets, while a single, maximum sized message of 66000 bytes, carried across a 1500 MTU network consists of 46 packets. This leads to the following scenario (among others leading to the same situation): 1: Msg 1 of 46 packets is sent. 20 packets go to the transmit queue, 26 packets to the backlog queue. 2: Msg 2 of 46 packets is attempted sent, but rejected because there is no more space in the backlog queue at this level. The sender is added to the wakeup queue with a "pending packets chain size" number of 46. 3: Some packets in the transmit queue are acked and released. We try to wake up the sender, but the pending size of 46 is bigger than the LOW wakeup limit of 30, so this doesn't happen. 5: Subsequent acks releases all the remaining buffers. Each time we test for the wakeup criteria and find that 46 still is larger than 30, even after both the transmit and the backlog queues are empty. 6: The sender is never woken up and given a chance to send its message. He is stuck. We could now loosen the wakeup criteria (used by link_prepare_wakeup()) to become equal to the send criteria (used by tipc_link_xmit()), i.e., by ignoring the "pending packets chain size" value altogether, or we can just increase the queue limits so that the criteria can be satisfied anyway. There are good reasons (potentially multiple waiting senders) to not opt for the former solution, so we choose the latter one. This commit fixes the problem by giving the broadcast link window a default value of 50 packets. We also introduce a new minimum link window size BCLINK_MIN_WIN of 32, which is enough to always avoid the described situation. Finally, in order to not break any existing users which may set the window explicitly, we enforce that the window is set to the new minimum value in case the user is trying to set it to anything lower.
