The function brcmf_usb_dlneeded() queries the device to obtain the chip id and revision. So assigning these in bus interface before the call resulted in chip id and revision being zero. This was introduced by: commit 5b8045d4 Author: Arend van Spriel <arend@broadcom.com> Date: Tue May 27 12:56:23 2014 +0200 brcmfmac: use asynchronous firmware request in USB Reviewed-by:

https://bugzilla.kernel.org/show_bug.cgi?id=70191 https://bugzilla.kernel.org/show_bug.cgi?id=77581 It is observed that sometimes Tx packet is downloaded without adding driver's txpd header. This results in firmware parsing garbage data as packet length. Sometimes firmware is unable to read the packet if length comes out as invalid. This stops further traffic and timeout occurs. The root cause is uninitialized fields in tx_info(skb->cb) of packet used to get garbage values. In this case if MWIFIEX_BUF_FLAG_REQUEUED_PKT flag is mistakenly set, txpd header was skipped. This patch makes sure that tx_info is correctly initialized to fix the problem. Cc: <stable@vger.kernel.org> Reported-by:

The current sched scan channel configuration code configures all the supported channels for scanning. However, this can result in SYSASSERT in some cases, when the configured channel is disabled. Instead, configure only the channels given in the req struct, and set the channel_count field appropriately. While on it, change the code to use channel->hw_value instead of recalculating the channel number. Signed-off-by:

When detecting a non-link packet, h5_reset_rx() frees the Rx skb. Not returning after that will cause the upcoming h5_rx_payload() call to dereference a now NULL Rx skb and trigger a kernel oops. Signed-off-by:

When pairing fails hci_conn refcnt drops below zero. This cause that ACL link is not disconnected when disconnect timeout fires. Probably this is because l2cap_conn_del calls l2cap_chan_del for each channel, and inside l2cap_chan_del conn is dropped. After that loop hci_chan_del is called which also drops conn. Anyway, as it is desrcibed in hci_core.h, it is known that refcnt drops below 0 sometimes and it should be fine. If so, let disconnect link when hci_conn_timeout fires and refcnt is 0 or below. This patch does it.

This reverts commit ca58e594. For some unclear reason this patch tries to add suport for the product ID 0xe005, but it ends up adding product ID 0x3005 to all the tables. This is obviously wrong and causing multiple issues. The original patch seemed to be fine, but what ended up in 3.15 is not what the patch intended. The commit 0a3658cc is already present and adds support for this hardware. This means only revert of this broken commit is requird. Signed-off-by:

As reported by Niels, starting rfkill polling during device probe (commit e2bc7c5f, generally sane change) broke rfkill on rt2500pci device. I considered that bug as some initalization issue, which should be fixed on rt2500pci specific code. But after several attempts (see bug report for details) we fail to find working solution. Hence I decided to revert to old behaviour on rt2500pci to fix regression. Additionally patch also unregister rfkill on device remove instead of ifconfig down, what was another issue introduced by bad commit.

Support for firmware rev 508+ was added years ago, but we never noticed it reports channel in a different way for G-PHY devices. Instead of offset from 2400 MHz it simply passes channel id (AKA hw_value).

The device 057c:8501 (AVM Fritz! WLAN v2 rev. B) boots into a state that does not actually require loading a firmware file. The vendors driver finds out about this by checking a firmware state register, so this patch adds this here.

The device 057c:8501 (AVM Fritz! WLAN v2 rev. B) currently does not load. One thing observed is that the vendors driver detects EFUSE mode for this device, but rt2800usb does not. This is due to rt2800usb lacking a check for the firmware mode present in the vendors driver, that this patch adopts for rt2800usb. With this patch applied, the 'RF chipset' detection does no longer fail. Signed-off-by:

On PCIe Tx data path, network interface specific tx_info parameters such as bss_num and bss_type are saved at "skb->cb + sizeof(dma_addr_t)" (returned by MWIFIEX_SKB_TXCB). Later mwifiex_map_pci_memory() called from mwifiex_pcie_send_data() will memcpy sizeof(struct mwifiex_dma_mapping) bytes to save PCIe DMA address and length information at beginning of skb->cb. This accidently overwrites bss_num and bss_type saved in skb->cb previously because bss_num/bss_type and mwifiex_dma_mapping data overlap. Similarly, on PCIe Rx data path, rx_info parameters overlaps with PCIe DMA address and length information too. Fix it by defining mwifiex_cb structure and having MWIFIEX_SKB_TXCB and MWIFIEX_SKB_RXCB return the correct address of tx_info/rx_info using the structure members. Also add a BUILD_BUG_ON to maks sure that mwifiex_cb structure doesn't exceed the size of skb->cb. Reviewed-by:

Commit 3fd091e7 ("[SCTP]: Remove multiple levels of msecs to jiffies conversions.") has silently changed permissions for rto_alpha and rto_beta knobs from 0644 to 0444. The purpose of this was to discourage users from tweaking rto_alpha and rto_beta knobs in production environments since they are key to correctly compute rtt/srtt. RFC4960 under section 6.3.1. RTO Calculation says regarding rto_alpha and rto_beta under rule C3 and C4: [...] C3) When a new RTT measurement R' is made, set RTTVAR <- (1 - RTO.Beta) * RTTVAR + RTO.Beta * |SRTT - R'| and SRTT <- (1 - RTO.Alpha) * SRTT + RTO.Alpha * R' Note: The value of SRTT used in the update to RTTVAR is its value before updating SRTT itself using the second assignment. After the computation, update RTO <- SRTT + 4 * RTTVAR. C4) When data is in flight and when allowed by rule C5 below, a new RTT measurement MUST be made each round trip. Furthermore, new RTT measurements SHOULD be made no more than once per round trip for a given destination transport address. There are two reasons for this recommendation: First, it appears that measuring more frequently often does not in practice yield any significant benefit [ALLMAN99]; second, if measurements are made more often, then the values of RTO.Alpha and RTO.Beta in rule C3 above should be adjusted so that SRTT and RTTVAR still adjust to changes at roughly the same rate (in terms of how many round trips it takes them to reflect new values) as they would if making only one measurement per round-trip and using RTO.Alpha and RTO.Beta as given in rule C3. However, the exact nature of these adjustments remains a research issue. [...] While it is discouraged to adjust rto_alpha and rto_beta and not further specified how to adjust them, the RFC also doesn't explicitly forbid it, but rather gives a RECOMMENDED default value (rto_alpha=3, rto_beta=2). We have a couple of users relying on the old permissions before they got changed. That said, if someone really has the urge to adjust them, we could allow it with a warning in the log.

Geert reported issues regarding checksum complete and UDP. The logic introduced in commit 7e3cead5 ("net: Save software checksum complete") is not correct. This patch: 1) Restores code in __skb_checksum_complete_header except for setting CHECKSUM_UNNECESSARY. This function may be calculating checksum on something less than skb->len. 2) Adds saving checksum to __skb_checksum_complete. The full packet checksum 0..skb->len is calculated without adding in pseudo header. This value is saved in skb->csum and then the pseudo header is added to that to derive the checksum for validation. 3) In both __skb_checksum_complete_header and __skb_checksum_complete, set skb->csum_valid to whether checksum of zero was computed. This allows skb_csum_unnecessary to return true without changing to CHECKSUM_UNNECESSARY which was done previously. 4) Copy new csum related bits in __copy_skb_header. Reported-by:

Joseph Gasparakis reported that VXLAN GSO offload stopped working with i40e device after recent UDP changes. The problem is that the SKB_GSO_* bits are out of sync with the corresponding NETIF flags. This patch fixes that. Also, we add BUILD_BUG_ONs in net_gso_ok for several GSO constants that were missing to avoid the problem in the future. Reported-by:
