There's no reason for preventing the creation and removal of qmimux network interfaces when the underlying interface is up. This makes qmi_wwan mux implementation more similar to the rmnet one, simplifying userspace management of the same logical interfaces.

This reverts commit 134f98bc. The r8153_mac_clk_spd() is used for RTL8153A only, because the register table of RTL8153B is different from RTL8153A. However, this function would be called when RTL8153B calls r8153_first_init() and r8153_enter_oob(). That causes RTL8153B becomes unstable when suspending and resuming. The worst case may let the device stop working. Besides, revert this commit to disable MAC clock speed down for RTL8153A. It would avoid the known issue when enabling U1. The data of the first control transfer may be wrong when exiting U1. Signed-off-by: NHayes Wang <hayeswang@realtek.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

For runtime resuming, the RTL8153B may be resumed from the state of power cut, when enabling the feature of UPS. Then, the PHY would be reset, so it is necessary to be initailized again. Besides, the USB_U1U2_TIMER also has to be set again, so I move it from r8153b_init() to r8153b_hw_phy_cfg().

Replace r8153_patch_request() with rtl_phy_patch_request(). Replace r8153_pre_ram_code() with rtl_pre_ram_code(). Replace r8153_post_ram_code() with rtl_post_ram_code(). Add rtl_patch_key_set(). The new functions have an additional parameter. It is used to wait the patch request command finished. When the PHY is resumed from the state of power cut, the PHY is at a safe mode and the OCP_PHY_PATCH_STAT wouldn't be updated. For this situation, it is safe to set patch request command without waiting OCP_PHY_PATCH_STAT. Signed-off-by: NHayes Wang <hayeswang@realtek.com> Signed-off-by: NJakub Kicinski <kuba@kernel.org>

This converts the driver to use the new tasklet API introduced in commit 12cc923f ("tasklet: Introduce new initialization API") It is unfortunate that we need to add a pointer to the driver context to get back to the usbnet device, but the space will be reclaimed once there are no more users of the old API left and we can remove the data value and flag from the tasklet struct.

Pass through mode is to allow packets in MAP format to be passed on to the stack. rmnet driver can be used to process and demultiplex these packets. Pass through mode can be enabled when the device is in raw ip mode only. Conversely, raw ip mode cannot be disabled when pass through mode is enabled. Userspace can use pass through mode in conjunction with rmnet driver through the following steps- 1. Enable raw ip mode on qmi_wwan device 2. Enable pass through mode on qmi_wwan device 3. Create a rmnet device with qmi_wwan device as real device using netlink Signed-off-by: NSubash Abhinov Kasiviswanathan <subashab@codeaurora.org> Acked-by: NBjørn Mork <bjorn@mork.no> Link: https://lore.kernel.org/r/1611560015-20034-1-git-send-email-subashab@codeaurora.orgSigned-off-by: NJakub Kicinski <kuba@kernel.org>

This commit enables the use of the r8153_ecm driver, introduced with commit c1aedf01 ("net/usb/r8153_ecm: support ECM mode for RTL8153") for the Lenovo Powered USB-C Hub (17ef:721e) based on the Realtek RTL8153B chip. This results in the following driver preference: - if r8152 is available, use the r8152 driver - if r8152 is not available, use the r8153_ecm driver This is done to prevent the NIC from constantly sending pause frames when the host system enters standby (fixed by using the r8152 driver in "r8152: Add Lenovo Powered USB-C Travel Hub"), while still allowing the device to work with the r8153_ecm driver as a fallback.

This USB-C Hub (17ef:721e) based on the Realtek RTL8153B chip used to use the cdc_ether driver. However, using this driver, with the system suspended the device constantly sends pause-frames as soon as the receive buffer fills up. This causes issues with other devices, where some Ethernet switches stop forwarding packets altogether. Using the Realtek driver (r8152) fixes this issue. Pause frames are no longer sent while the host system is suspended.

MSFT ActiveSync implementation requires that the size of the response for incoming query is to be provided in the request input length. Failure to set the input size proper results in failed request transfer, where the ActiveSync counterpart reports the NDIS_STATUS_INVALID_LENGTH (0xC0010014L) error. Set the input size for OID_GEN_PHYSICAL_MEDIUM query to the expected size of the response in order for the ActiveSync to properly respond to the request.

When measuring the throughput (iperf3 + TCP) while routing on a not-so-powerful device (Mediatek MT7621, 880MHz CPU), I noticed that I achieved significantly lower speeds with QMI-based modems than for example a USB LAN dongle. The CPU was saturated in all of my tests. With the dongle I got ~300 Mbit/s, while I only measured ~200 Mbit/s with the modems. All offloads, etc. were switched off for the dongle, and I configured the modems to use QMAP (16k aggregation). The tests with the dongle were performed in my local (gigabit) network, while the LTE network the modems were connected to delivers 700-800 Mbit/s. Profiling the kernel revealed the cause of the performance difference. In qmimux_rx_fixup(), an SKB is allocated for each packet contained in the URB. This SKB has too little headroom, causing the check in skb_cow() (called from ip_forward()) to fail. pskb_expand_head() is then called and the SKB is reallocated. In the output from perf, I see that a significant amount of time is spent in pskb_expand_head() + support functions. In order to ensure that the SKB has enough headroom, this commit increases the amount of memory allocated in qmimux_rx_fixup() by LL_MAX_HEADER. The reason for using LL_MAX_HEADER and not a more accurate value, is that we do not know the type of the outgoing network interface. After making this change, I achieve the same throughput with the modems as with the dongle.

Aligning to tx_ndp_modulus is not sufficient because the next align call can be cdc_ncm_align_tail, which can add up to ctx->tx_modulus + ctx->tx_remainder - 1 bytes. This used to lead to occasional crashes on a Huawei 909s-120 LTE module as follows: - the condition marked /* if there is a remaining skb [...] */ is true so the swaps happen - skb_out is set from ctx->tx_curr_skb - skb_out->len is exactly 0x3f52 - ctx->tx_curr_size is 0x4000 and delayed_ndp_size is 0xac (note that the sum of skb_out->len and delayed_ndp_size is 0x3ffe) - the for loop over n is executed once - the cdc_ncm_align_tail call marked /* align beginning of next frame */ increases skb_out->len to 0x3f56 (the sum is now 0x4002) - the condition marked /* check if we had enough room left [...] */ is false so we break out of the loop - the condition marked /* If requested, put NDP at end of frame. */ is true so the NDP is written into skb_out - now skb_out->len is 0x4002, so padding_count is minus two interpreted as an unsigned number, which is used as the length argument to memset, leading to a crash with various symptoms but usually including > Call Trace: > <IRQ> > cdc_ncm_fill_tx_frame+0x83a/0x970 [cdc_ncm] > cdc_mbim_tx_fixup+0x1d9/0x240 [cdc_mbim] > usbnet_start_xmit+0x5d/0x720 [usbnet] The cdc_ncm_align_tail call first aligns on a ctx->tx_modulus boundary (adding at most ctx->tx_modulus-1 bytes), then adds ctx->tx_remainder bytes. Alternatively, the next alignment call can occur in cdc_ncm_ndp16 or cdc_ncm_ndp32, in which case at most ctx->tx_ndp_modulus-1 bytes are added. A similar problem has occurred before, and the code is nontrivial to reason about, so add a guard before the crashing call. By that time it is too late to prevent any memory corruption (we'll have written past the end of the buffer already) but we can at least try to get a warning written into an on-disk log by avoiding the hard crash caused by padding past the buffer with a huge number of zeros.

Starting with iOS 14 released in September 2020, connectivity using the personal hotspot USB tethering function of iOS devices is broken. Communication between the host and the device (for example ICMP traffic or DNS resolution using the DNS service running in the device itself) works fine, but communication to endpoints further away doesn't work. Investigation on the matter shows that no UDP and ICMP traffic from the tethered host is reaching the Internet at all. For TCP traffic there are exchanges between tethered host and server but packets are modified in transit leading to impossible communication. After some trials Matti Vuorela discovered that reducing the URB buffer size by two bytes restored the previous behavior. While a better solution might exist to fix the issue, since the protocol is not publicly documented and considering the small size of the fix, let's do that.
