One of the modes of Huawei E367 has this QMI/wwan interface: I:* If#= 1 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=01 Prot=07 Driver=(none) E: Ad=83(I) Atr=03(Int.) MxPS= 64 Ivl=2ms E: Ad=84(I) Atr=02(Bulk) MxPS= 512 Ivl=0ms E: Ad=02(O) Atr=02(Bulk) MxPS= 512 Ivl=4ms Huawei use subclass and protocol to identify vendor specific functions, so adding a new vendor rule for this combination. The Pantech devices UML290 (106c:3718) and P4200 (106c:3721) use the same subclass to identify the QMI/wwan function. Replace the existing device specific UML290 entries with generic vendor matching, adding support for the Pantech P4200. The ZTE MF683 has 6 vendor specific interfaces, all using ff/ff/ff for cls/sub/prot. Adding a match on interface #5 which is a QMI/wwan interface.

This fixes a hang on suspend due to calling wdm_suspend on the unregistered data interface. The hang should have been a NULL pointer reference had it not been for a logic error in the cdc_wdm code. commit 230718bd net: qmi_wwan: bind to both control and data interface changed qmi_wwan to use cdc_wdm as a subdriver for devices with a two-interface QMI/wwan function. The commit failed to update qmi_wwan_suspend and qmi_wwan_resume, which were written to handle either a single combined interface function, or no subdriver at all. The result was that we called into the subdriver both when the control interface was suspended and when the data interface was suspended. Calling the subdriver suspend function with an unregistered interface is not supported and will make the subdriver bug out. Signed-off-by: NBjørn Mork <bjorn@mork.no> Signed-off-by: NDavid S.

Suspending an open usbnet device results in constant rescheduling of usbnet_bh. commit 65841fd5 "usbnet: handle remote wakeup asap" refactored the usbnet_bh code to allow sharing the urb allocate and submit code with usbnet_resume. In this process, a test for, and immediate return on, ENOLINK from rx_submit was unintentionally dropped. The rx queue will not grow if rx_submit fails, making usbnet_bh reschedule itself. This results in a softirq storm if the error is persistent. rx_submit translates the usb_submit_urb error EHOSTUNREACH into ENOLINK, so this is an expected and persistent error for a suspended device. The old code tested for this condition and avoided rescheduling. Putting this test back.

Add 6 new devices and one modified device, based on information from laptop vendor Windows drivers. Sony provides a driver with two new devices using a Gobi 2k+ layout (1199:68a5 and 1199:68a9). The Sony driver also adds a non-standard QMI/net interface to the already supported 1199:9011 Gobi device. We do not know whether this is an alternate interface number or an additional interface which might be present, but that doesn't really matter. Lenovo provides a driver supporting 4 new devices: - MC7770 (1199:901b) with standard Gobi 2k+ layout - MC7700 (0f3d:68a2) with layout similar to MC7710 - MC7750 (114f:68a2) with layout similar to MC7710 - EM7700 (1199:901c) with layout similar to MC7710 Note regaring the three devices similar to MC7710: The Windows drivers only support interface #8 on these devices. The MC7710 can support QMI/net functions on interface #19 and #20 as well, and this driver is verified to work on interface #19 (a firmware bug is suspected to prevent #20 from working). We do not enable these additional interfaces until they either show up in a Windows driver or are verified to work in some other way. Therefore limiting the new devices to interface #8 for now.

The driver has had its own interface number whitelisting code to simulate this functionality. Replace this with generic interface number matching now that the USB subsystem support is there. This - removes the need for a driver_info structure per interface number, - avoids running the probe function for unsupported interfaces, and - simplifies the code.

We allocate memory for 'req' with usb_alloc_urb() and then test 'if (!req || rx_submit(pnd, req, GFP_KERNEL | __GFP_COLD))'. If we enter that branch due to '!req' then there is no problem. But if we enter the branch due to 'req' being != 0 and the 'rx_submit()' call being false, then we'll leak the memory we allocated. Deal with the leak by always calling 'usb_free_urb(req)' when entering the branch. If 'req' happens to be 0 then the call is harmless, if it is not 0 then we free the memory we allocated but don't need.

The skb->pfmemalloc flag gets set to true iff during the slab allocation of data in __alloc_skb that the the PFMEMALLOC reserves were used. If page splitting is used, it is possible that pages will be allocated from the PFMEMALLOC reserve without propagating this information to the skb. This patch propagates page->pfmemalloc from pages allocated for fragments to the skb. It works by reintroducing and expanding the skb_alloc_page() API to take an skb. If the page was allocated from pfmemalloc reserves, it is automatically copied. If the driver allocates the page before the skb, it should call skb_propagate_pfmemalloc() after the skb is allocated to ensure the flag is copied properly. Failure to do so is not critical. The resulting driver may perform slower if it is used for swap-over-NBD or swap-over-NFS but it should not result in failure.

The current code for reading the EEPROM via ethtool in the asix driver has a few issues. It cannot handle odd length values (accesses must be aligned at 16 bit boundaries) and interprets the offset provided by ethtool as 16 bit word offset instead as byte offset. The new code for asix_get_eeprom() introduced by this patch is modeled after the code in drivers/net/ethernet/atheros/atl1e/atl1e_ethtool.c and provides read access to the entire EEPROM with arbitrary offsets and lengths.

The usbnet API use the device ID table to store a pointer to a minidriver. Setting a generic pointer for dynamic device IDs will in most cases make them work as expected. usbnet will otherwise treat the dynamic IDs as blacklisted. That is rarely useful. There is no standard class describing devices supported by this driver, and most vendors don't even provide enough information to allow vendor specific wildcard matching. The result is that most of the supported devices must be explicitly listed in the device table. Allowing dynamic IDs to work both simplifies testing and verification of new devices, and provides a way for end users to use a device before the ID is added to the driver.

I noticed excess calls to skb_copy_expand() or memmove() in asix driver. This driver needs to push 4 bytes in front of frame (packet_len) and maybe add 4 bytes after the end (if padlen is 4) So it should set needed_headroom & needed_tailroom to avoid copies. But its not enough, because many packets are cloned before entering asix_tx_fixup() and this driver use skb_cloned() as a lazy way to check if it can push and put additional bytes in frame. Avoid skb_copy_expand() expensive call, using following rules : - We are allowed to push 4 bytes in headroom if skb_header_cloned() is false (and if we have 4 bytes of headroom) - We are allowed to put 4 bytes at tail if skb_cloned() is false (and if we have 4 bytes of tailroom) TCP packets for example are cloned, but skb_header_release() was called in tcp stack, allowing us to use headroom for our needs.

usbnet_disconnect() will set intfdata to NULL before calling the minidriver unbind function. The cdc_wdm subdriver cannot know that it is disconnecting until the qmi_wwan unbind function has called its disconnect function. This means that we must be able to support the cdc_wdm subdriver operating normally while usbnet_disconnect() is running, and in particular that intfdata may be NULL. The only place this matters is in qmi_wwan_cdc_wdm_manage_power which is called from cdc_wdm. Simply testing for NULL intfdata there is sufficient to allow it to continue working at all times. Fixes this Oops where a cdc-wdm device was closed while the USB device was disconnecting, causing wdm_release to call qmi_wwan_cdc_wdm_manage_power after intfdata was set to NULL by usbnet_disconnect: [41819.087460] BUG: unable to handle kernel NULL pointer dereference at 00000080 [41819.087815] IP: [<f8640458>] qmi_wwan_manage_power+0x68/0x90 [qmi_wwan] [41819.088028] *pdpt = 000000000314f001 *pde = 0000000000000000 [41819.088028] Oops: 0002 [#1] SMP [41819.088028] Modules linked in: qmi_wwan option usb_wwan usbserial usbnet cdc_wdm nls_iso8859_1 nls_cp437 vfat fat usb_storage bnep rfcomm bluetooth parport_pc ppdev binfmt_misc iptable_nat nf_nat nf_conntrack_ipv4 nf_conntrack nf_defrag_ipv4 iptable_mangle iptable_filter ip_tables x_tables dm_crypt uvcvideo snd_hda_codec_realtek snd_hda_intel videobuf2_core snd_hda_codec joydev videodev videobuf2_vmalloc hid_multitouch snd_hwdep arc4 videobuf2_memops snd_pcm snd_seq_midi snd_rawmidi snd_seq_midi_event ath9k mac80211 snd_seq ath9k_common ath9k_hw ath snd_timer snd_seq_device sparse_keymap dm_multipath scsi_dh coretemp mac_hid snd soundcore cfg80211 snd_page_alloc psmouse serio_raw microcode lp parport dm_mirror dm_region_hash dm_log usbhid hid i915 drm_kms_helper drm r8169 i2c_algo_bit wmi video [last unloaded: qmi_wwan] [41819.088028] [41819.088028] Pid: 23292, comm: qmicli Not tainted 3.4.0-5-generic #11-Ubuntu GIGABYTE T1005/T1005 [41819.088028] EIP: 0060:[<f8640458>] EFLAGS: 00010246 CPU: 1 [41819.088028] EIP is at qmi_wwan_manage_power+0x68/0x90 [qmi_wwan] [41819.088028] EAX: 00000000 EBX: 00000000 ECX: 000000c3 EDX: 00000000 [41819.088028] ESI: c3b27658 EDI: 00000000 EBP: c298bea4 ESP: c298be98 [41819.088028] DS: 007b ES: 007b FS: 00d8 GS: 00e0 SS: 0068 [41819.088028] CR0: 8005003b CR2: 00000080 CR3: 3605e000 CR4: 000007f0 [41819.088028] DR0: 00000000 DR1: 00000000 DR2: 00000000 DR3: 00000000 [41819.088028] DR6: ffff0ff0 DR7: 00000400 [41819.088028] Process qmicli (pid: 23292, ti=c298a000 task=f343b280 task.ti=c298a000) [41819.088028] Stack: [41819.088028] 00000000 c3b27658 e2a80d00 c298beb0 f864051a c3b27600 c298bec0 f9027099 [41819.088028] c2fd6000 00000008 c298bef0 c1147f96 00000001 00000000 00000000 f4e54790 [41819.088028] ecf43a00 ecf43a00 c2fd6008 c2fd6000 ebbd7600 ffffffb9 c298bf08 c1144474 [41819.088028] Call Trace: [41819.088028] [<f864051a>] qmi_wwan_cdc_wdm_manage_power+0x1a/0x20 [qmi_wwan] [41819.088028] [<f9027099>] wdm_release+0x69/0x70 [cdc_wdm] [41819.088028] [<c1147f96>] fput+0xe6/0x210 [41819.088028] [<c1144474>] filp_close+0x54/0x80 [41819.088028] [<c1046a65>] put_files_struct+0x75/0xc0 [41819.088028] [<c1046b56>] exit_files+0x46/0x60 [41819.088028] [<c1046f81>] do_exit+0x141/0x780 [41819.088028] [<c107248f>] ? wake_up_state+0xf/0x20 [41819.088028] [<c1053f48>] ? signal_wake_up+0x28/0x40 [41819.088028] [<c1054f3b>] ? zap_other_threads+0x6b/0x80 [41819.088028] [<c1047864>] do_group_exit+0x34/0xa0 [41819.088028] [<c10478e8>] sys_exit_group+0x18/0x20 [41819.088028] [<c15bb7df>] sysenter_do_call+0x12/0x28 [41819.088028] Code: 04 83 e7 01 c1 e7 03 0f b6 42 18 83 e0 f7 09 f8 88 42 18 8b 43 04 e8 48 9a dd c8 89 f0 8b 5d f4 8b 75 f8 8b 7d fc 89 ec 5d c3 90 <f0> ff 88 80 00 00 00 0f 94 c0 84 c0 75 b7 31 f6 8b 5d f4 89 f0 [41819.088028] EIP: [<f8640458>] qmi_wwan_manage_power+0x68/0x90 [qmi_wwan] SS:ESP 0068:c298be98 [41819.088028] CR2: 0000000000000080 [41819.149492] ---[ end trace 0944479ff8257f55 ]--- Reported-by: NMarius Bjørnstad Kotsbak <marius.kotsbak@gmail.com> Cc: <stable@vger.kernel.org> # v3.4 Signed-off-by: NBjørn Mork <bjorn@mork.no> Signed-off-by: NDavid S.

If usbnet is resumed by remote wakeup, generally there are some packets comming to be handled, so allocate and submit rx URBs in usbnet_resume to avoid delays introduced by tasklet. Otherwise, usbnet may have been runtime suspended before the usbnet_bh is executed to schedule Rx URBs. Without the patch, usbnet can't recieve any packets from peer in runtime suspend state if runtime PM is enabled and autosuspend_delay is set as zero.
