Adjust driver behavior during FW boot. Proper sequence of events after reset and FW download, is as following: - FW prepares mailbox structure and reports IRQ "FW_READY" - driver caches mailbox registers, marks mailbox readiness - FW sends WMI_FW_READY event, ignore it - FW sends WMI_READY event with some data - driver stores relevant data marks FW is operational Signed-off-by: NVladimir Kondratiev <qca_vkondrat@qca.qualcomm.com> Signed-off-by: NKalle Valo <kvalo@qca.qualcomm.com>

For the messages from host to target, shadow copy of CE descriptors are maintained in source ring. Before writing actual CE descriptor, first shadow copy is filled and then it is copied to CE address space. To optimize in download path and to reduce d-cache pressure, removing shadow copy of CE descriptors. This will also reduce driver memory consumption by 33KB during on device probing.

The physical address necessary to unmap DMA ('bufferp') is stored in ath10k_skb_cb as 'paddr'. ath10k doesn't rely on the meta/transfer_id when handling send completion (htc ep id is stored in sk_buff control buffer). So the unused output arguments {bufferp, nbytesp and transfer_idp} are removed from CE send completion. This change is needed before removing the shadow copy of copy engine (CE) descriptors in follow up patch.

Currently to avoid uncached memory access while filling up copy engine descriptors, shadow descriptors are used. This can be optimized further by removing shadow descriptors.

European Union has made it mandatory that all devices working in 2.4 GHz has to adhere to the ETSI specification (ETSI EN 300 328 V1.9.1) beginnig this year. The standard basically speaks about interferences in 2.4Ghz band. For example, when 802.11 device detects interference, TX must be stopped as long as interference is present. Adaptive CCA is a feature, when enabled the device learns from the environment and configures CCA levels adaptively. This will improve detecting interferences and the device can stop trasmissions till the interference is present eventually leading to good performances in varying interference conditions. The patch includes code for enabling adaptive CCA for 10.2.4 firmware on QCA988X.

ssb bus can be found on various "host" devices like PCI/PCMCIA/SDIO. Every ssb bus contains cores AKA devices. The main idea is to have ssb driver scan/initialize bus and register ready-to-use cores. This way ssb drivers can operate on a single core mostly ignoring underlaying details. For some reason PCMCIA support was split between ssb and b43. We got PCMCIA host device probing in b43, then bus scanning in ssb and then wireless core probing back in b43. The truth is it's very unlikely we will ever see PCMCIA ssb device with no 802.11 core but I still don't see any advantage of the current architecture. With proposed change we get the same functionality with a simpler architecture, less Kconfig symbols, one killed EXPORT and hopefully cleaner b43. Since b43 supports both: ssb & bcma I prefer to keep ssb specific code in ssb driver. This mostly moves code from b43's pcmcia.c to bridge_pcmcia_80211.c. We already use similar solution with b43_pci_bridge.c. I didn't use "b43" in name of this new file as in theory any driver can operate on wireless core.

In uap mode the carrier is not enabled until after the first STA joins. The carrier triggers the bridge to start its state machine, and if STP is enabled, it takes 4 seconds as it transitions from disabled to forwarding. During this time the bridge drops all traffic, and the EAPOL handshake times out after 3 seconds, preventing stations from joining. Follow the logic used in mac80211 and start the carrier in start_ap and disable it in stop_ap. This has a nice benefit of allowing the first station connection time to be reduced by up to 75% when STP is in use.

wcn36xx implements a ring buffer for transmitted frames for each (high and low priority) DMA channel. The ring buffers are lockless: new frames are inserted at the head of the queue, while finished packets are reaped from the tail. Unfortunately, the list manipulations are missing any kind of barriers so are susceptible to various races: for example, a TX completion handler might read an updated desc->ctrl before the head has actually advanced, and then null out the ctl->skb pointer while it is still being used in the TX path. Simplify things here by adding a spin lock when traversing the ring. This change increased stability for me without adding any noticeable overhead on my platform (xperia z).

Some of the ath9k_phyerr enums were wrong from the beginning (and even before). Most of the time the codes were used for counters to be displayed over debugfs, which made this a non-functional issue. Some (e.g. ATH9K_PHYERR_FALSE_RADAR_EXT) are used for radar detection and require the correct code to work as intended. This patch includes: a) fixes ATH9K_PHYERR_FALSE_RADAR_EXT: 24 => 36 ATH9K_PHYERR_CCK_LENGTH_ILLEGAL: 32 => 28 ATH9K_PHYERR_CCK_POWER_DROP: 33 => 29 ATH9K_PHYERR_HT_CRC_ERROR: 34 => 32 ATH9K_PHYERR_HT_LENGTH_ILLEGAL: 35 => 33 ATH9K_PHYERR_HT_RATE_ILLEGAL: 36 => 34 b) extensions ATH9K_PHYERR_CCK_BLOCKER = 24 ATH9K_PHYERR_HT_ZLF = 35 ATH9K_PHYERR_GREEN_FIELD = 37 Aside from the correction and completion made in the enum, the patch also extends the display of the related counters in the debugfs.

This patch adds support for dumping a process' (classic BPF) seccomp filters via ptrace. PTRACE_SECCOMP_GET_FILTER allows the tracer to dump the user's classic BPF seccomp filters. addr should be an integer which represents the ith seccomp filter (0 is the most recently installed filter). data should be a struct sock_filter * with enough room for the ith filter, or NULL, in which case the filter is not saved. The return value for this command is the number of BPF instructions the program represents, or negative in the case of errors. Command specific errors are ENOENT: which indicates that there is no ith filter in this seccomp tree, and EMEDIUMTYPE, which indicates that the ith filter was not installed as a classic BPF filter. A caveat with this approach is that there is no way to get explicitly at the heirarchy of seccomp filters, and users need to memcmp() filters to decide which are inherited. This means that a task which installs two of the same filter can potentially confuse users of this interface. v2: * make save_orig const * check that the orig_prog exists (not necessary right now, but when grows eBPF support it will be) * s/n/filter_off and make it an unsigned long to match ptrace * count "down" the tree instead of "up" when passing a filter offset v3: * don't take the current task's lock for inspecting its seccomp mode * use a 0x42** constant for the ptrace command value v4: * don't copy to userspace while holding spinlocks v5: * add another condition to WARN_ON v6: * rebase on net-next Signed-off-by: NTycho Andersen <tycho.andersen@canonical.com> Acked-by: NKees Cook <keescook@chromium.org> CC: Will Drewry <wad@chromium.org> Reviewed-by: NOleg Nesterov <oleg@redhat.com> CC: Andy Lutomirski <luto@amacapital.net> CC: Pavel Emelyanov <xemul@parallels.com> CC: Serge E.

Robert Shearman says: ==================== mpls: mulipath improvements Two improvements to the recently added mpls multipath support. The first is a fix for missing initialisation the nexthop address length for the v4 and v6 explicit null label routes, and the second is to reduce the amount of memory used by mpls routes by changing the way the via addresses are stored. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

由 Robert Shearman 提交于
Nexthops for MPLS routes have a via address field sized for the largest via address that is expected, which is 32 bytes. This means that in the most common case of having ipv4 via addresses, 28 bytes of memory more than required are used per nexthop. In the other common case of an ipv6 nexthop then 16 bytes more than required are used. With large numbers of MPLS routes this extra memory usage could start to become significant. To avoid allocating memory for a maximum length via address when not all of it is required and to allow for ease of iterating over nexthops, then the via addresses are changed to be stored in the same memory block as the route and nexthops, but in an array after the end of the array of nexthops. New accessors are provided to retrieve a pointer to the via address. To allow for O(1) access without having to store a pointer or offset per nh, the via address for each nexthop is sized according to the maximum via address for any nexthop in the route, which is stored in a new route field, rt_max_alen, but this is in an existing hole in struct mpls_route so it doesn't increase the size of the structure. Each via address is ensured to be aligned to VIA_ALEN_ALIGN to account for architectures that don't allow unaligned accesses.
