Marvell p2p device disappears from the list of p2p peers on the other p2p device after disconnection. It happens due to a bug in driver. When interface is changed from p2p to station, certain variables(bss_type, bss_role etc.) aren't correctly updated. This patch corrects them to fix the issue. Signed-off-by:

It is observed that if single tid 6 packet comes among with massive tid 0 packets, tid 6 packet may stay in it's queue and will never be transmited. This is because wmm.highest_queued_prio will be set to 2 during transmission of tid 0 packets As a result, main work thread keeps on looping without serving that packet. In this case, if command has downloaded to firmware, driver doesn't process it's response causing command timeout. This patch will reset highest_queued_prio if packets exist in data queue, and try to find a ra_list for current private. Signed-off-by:

Following is mwifiex driver-firmware host sleep handshake. It involves three threads. suspend handler, interrupt handler, interrupt processing in main work queue. 1) Enter suspend handler 2) Download HS_CFG command 3) Response from firmware for HS_CFG 4) Suspend thread waits until handshake completes(i.e hs_activate becomes true) 5) SLEEP from firmware 6) SLEEP confirm downloaded to firmware. 7) SLEEP confirm response from firmware 8) Driver processes SLEEP confirm response and set hs_activate to wake up suspend thread 9) Exit suspend handler 10) Read sleep cookie in loop and wait until it indicates firmware is sleep. 11) After processing SLEEP confirm response, we are at the end of interrupt processing routine. Recheck if there are interrupts received while we were processing them. During suspend-resume stress test, it's been observed that we may end up acessing PCIe hardware(in 10 and 11) when PCIe bus is closed which leads to a kernel crash. This patch solves the problem with below changes. a) action 10 above can be done before 8 b) Skip 11 if hs_activated is true. SLEEP confirm response is the last interrupt from firmware. No need to recheck for pending interrupts. c) Add flush_workqueue() in suspend handler. Signed-off-by:

So far our core code was calling brcmf_fws_process_skb which wasn't a proper thing to do. If case of devices using msgbuf protocol fwsignal shouldn't be used. It was an unnecessary extra layer simply calling a protocol specifix txdata function. Please note we already have txdata callback, but it's used for calls between bcdc and fwsignal so it couldn't be simply used there. This makes core code more generic (instead of bcdc/fwsignal specific). Signed-off-by:

On some devices the EEPROMs of Ralink Wi-Fi chips have a default Ralink MAC address set (RT3062F: 00:0C:43:30:62:00, RT3060F: 00:0C:43:30:60:00). Using multiple of these devices in the same network can cause nasty issues. Allow to override the MAC in the EEPROM with (a known good) one set in the device tree to bypass the issue. Signed-off-by:

firewire-net, like the older eth1394 driver, reduced the initial MTU to less than 1500 octets if the local link layer controller's asynchronous packet reception limit was lower. This is bogus, since this reception limit does not have anything to do with the transmission limit. Neither did this reduction affect the TX path positively, nor could it prevent link fragmentation at the RX path. Many FireWire CardBus cards have a max_rec of 9, causing an initial MTU of 1024 - 16 = 1008. RFC 2734 and RFC 3146 allow a minimum max_rec = 8, which would result in an initial MTU of 512 - 16 = 496. On such cards, IPv6 could only be employed if the MTU was manually increased to 1280 or more, i.e. IPv6 would not work without intervention from userland. We now always initialize the MTU to 1500, which is the default according to RFC 2734 and RFC 3146. On a VIA VT6316 based CardBus card which was affected by this, changing the MTU from 1008 to 1500 also increases TX bandwidth by 6 %. RX remains unaffected.

Commit b3e3893e ("net: use core MTU range checking in misc drivers") mistakenly introduced an upper limit for firewire-net's MTU based on the local link layer controller's reception capability. Revert this. Neither RFC 2734 nor our implementation impose any particular upper limit. Actually, to be on the safe side and to make the code explicit, set ETH_MAX_MTU = 65535 as upper limit now. (I replaced sizeof(struct rfc2734_header) by the equivalent RFC2374_FRAG_HDR_SIZE in order to avoid distracting long/int conversions.)

Use setup_timer() instead of init_timer(), being the preferred/standard way to set a timer up. Also, quoting the mod_timer() function comment: -> mod_timer() is a more efficient way to update the expire field of an active timer (if the timer is inactive it will be activated). Use setup_timer and mod_timer to setup and arm a timer, to make the code cleaner and easier to read. Signed-off-by:

The maximum MTU is defined via the slave devices of an batman-adv interface. Thus it is not possible to calculate the max_mtu during the creation of the batman-adv device when no slave devices are attached. Doing so would for example break non-fragmentation setups which then (incorrectly) allow an MTU of 1500 even when underlying device cannot transport 1500 bytes + batman-adv headers. Checking the dynamically calculated max_mtu via the minimum of the slave devices MTU during .ndo_change_mtu is also used by the bridge interface.

iwlmvm currently uses dev_coredumpm() to collect multiple buffers, but this has the downside of pinning the module until the coredump expires, if the data isn't read by any userspace. Avoid this by using the new dev_coredumpsg() method. We still copy the data from the old way of generating it, but neither hold on to vmalloc'ed data for a long time, nor do we pin the module now.

New firmwares support dynamic queue allocation (DQA), which enables on-demand allocation of queues per RA/TID, instead of allocating them statically per vif. This allows an AP to send, for instance, BE traffic to STA2 even if it also needs to send traffic to a sleeping STA1, without being blocked by the sleeping station. The implementation in the driver is now ready, so we can enable this feature by default when running firmwares that support it. Signed-off-by:

In criu we are actively using diag interface to collect sockets present in the system when dumping applications. And while for unix, tcp, udp[lite], packet, netlink it works as expected, the raw sockets do not have. Thus add it. v2: - add missing sock_put calls in raw_diag_dump_one (by eric.dumazet@) - implement @destroy for diag requests (by dsa@) v3: - add export of raw_abort for IPv6 (by dsa@) - pass net-admin flag into inet_sk_diag_fill due to changes in net-next branch (by dsa@) v4: - use @pad in struct inet_diag_req_v2 for raw socket protocol specification: raw module carries sockets which may have custom protocol passed from socket() syscall and sole @sdiag_protocol is not enough to match underlied ones - start reporting protocol specifed in socket() call when sockets are raw ones for the same reason: user space tools like ss may parse this attribute and use it for socket matching v5 (by eric.dumazet@): - use sock_hold in raw_sock_get instead of atomic_inc, we're holding (raw_v4_hashinfo|raw_v6_hashinfo)->lock when looking up so counter won't be zero here. v6: - use sdiag_raw_protocol() helper which will access @pad structure used for raw sockets protocol specification: we can't simply rename this member without breaking uapi v7: - sine sdiag_raw_protocol() helper is not suitable for uapi lets rather make an alias structure with proper names. __check_inet_diag_req_raw helper will catch if any of structure unintentionally changed.
