ALSA: usb-audio: Fix parsing descriptor of UAC2 processing unit

2018-04-08T09:49:39Z

commit a6618f4aedb2b60932d766bd82ae7ce866e842aa upstream. Currently, the offsets in the UAC2 processing unit descriptor are calculated incorrectly. It causes an issue when connecting the device which provides such a feature: ~~~~ [84126.724420] usb 1-1.3.1: invalid Processing Unit descriptor (id 18) ~~~~ After this patch is applied, the UAC2 processing unit inits w/o this error.

USB: fix out-of-bounds in usb_set_configuration

2017-10-12T07:18:02Z

commit bd7a3fe770ebd8391d1c7d072ff88e9e76d063eb upstream. Andrey Konovalov reported a possible out-of-bounds problem for a USB interface association descriptor. He writes: It seems there's no proper size check of a USB_DT_INTERFACE_ASSOCIATION descriptor. It's only checked that the size is >= 2 in usb_parse_configuration(), so find_iad() might do out-of-bounds access to intf_assoc->bInterfaceCount. And he's right, we don't check for crazy descriptors of this type very well, so resolve this problem. Yet another issue found by syzkaller...

USB: hub: fix SS max number of ports

2017-06-26T05:10:51Z

commit 93491ced3c87c94b12220dbac0527e1356702179 upstream. Add define for the maximum number of ports on a SuperSpeed hub as per USB 3.1 spec Table 10-5, and use it when verifying the retrieved hub descriptor. This specifically avoids benign attempts to update the DeviceRemovable mask for non-existing ports (should we get that far).

usb: gadget: f_fs: virtual endpoint address mapping

2014-09-16T14:58:21Z

This patch introduces virtual endpoint address mapping. It separates function logic form physical endpoint addresses making it more hardware independent. Following modifications changes user space API, so to enable them user have to switch on the FUNCTIONFS_VIRTUAL_ADDR flag in descriptors. Endpoints are now refered using virtual endpoint addresses chosen by user in endpoint descpriptors. This applies to each context when endpoint address can be used: - when accessing endpoint files in FunctionFS filesystemi (in file name), - in setup requests directed to specific endpoint (in wIndex field), - in descriptors returned by FUNCTIONFS_ENDPOINT_DESC ioctl. In endpoint file names the endpoint address number is formatted as double-digit hexadecimal value ("ep%02x") which has few advantages - it is easy to parse, allows to easly recognize endpoint direction basing on its name (IN endpoint number starts with digit 8, and OUT with 0) which can be useful for debugging purpose, and it makes easier to introduce further features allowing to use each endpoint number in both directions to have more endpoints available for function if hardware supports this (for example we could have ep01 which is endpoint 1 with OUT direction, and ep81 which is endpoint 1 with IN direction). Physical endpoint address can be still obtained using ioctl named FUNCTIONFS_ENDPOINT_REVMAP, but now it's not neccesary to handle USB transactions properly.

usb: gadget: f_fs: add ioctl returning ep descriptor

2014-09-09T15:04:45Z

This patch introduces ioctl named FUNCTIONFS_ENDPOINT_DESC, which returns endpoint descriptor to userspace. It works only if function is active. Signed-off-by: Robert Baldyga Acked-by: Michal Nazarewicz Signed-off-by: Felipe Balbi

tools: ffs-test: convert to new descriptor format

2014-09-02T14:16:46Z

Since commit [ac8dde11: “Add flags to descriptors block”] functionfs supports a new, more powerful and extensible, descriptor format. Since ffs-test is probably the first thing users of the functionfs interface see when they start writing functionfs user space daemons, convert it to use the new format thus promoting it.

usb: gadget: f_fs: add usb_functionfs_descs_head_v2 structure

2014-09-02T14:16:46Z

The structure can be used with user space tools that use the new functionfs description format, for example as follows: static const struct { struct usb_functionfs_descs_head_v2 header; __le32 fs_count; __le32 hs_count; struct { … } fs_desc; struct { … } hs_desc; } descriptors = { .header = { .magic = cpu_to_le32(FUNCTIONFS_DESCRIPTORS_MAGIC_V2), .length = cpu_to_le32(sizeof(descriptors)), .flags = cpu_to_le32(FUNCTIONFS_HAS_FS_DESC | FUNCTIONFS_HAS_HS_DESC) }, .fs_count = cpu_to_le32(X), .fs_desc = { … }, .hs_count = cpu_to_le32(Y), .hs_desc = { … } }; Signed-off-by: Michal Nazarewicz Signed-off-by: Felipe Balbi

Merge tag 'usb-for-v3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next

2014-07-21T18:33:41Z

Felipe writes: usb: patches for v3.17 merge window Surprisingly enough, while a big set of patches, the majority is composed of cleanups (using devm_*, fixing sparse errors, moving code around, adding const, etc). The highlights are addition of new support for PLX USB338x devices, and support for USB 2.0-only configurations of the DWC3 IP core. Signed-of-by: Felipe Balbi

usb: gadget: f_fs: OS descriptors support

2014-07-10T13:36:52Z

Add support for OS descriptors. The new format of descriptors is used, because the "flags" field is required for extensions. os_count gives the number of OSDesc[] elements. The format of descriptors is given in include/uapi/linux/usb/functionfs.h. For extended properties descriptor the usb_ext_prop_desc structure covers only a part of a descriptor, because the wPropertyNameLength is unknown up front.

usb: gadget: f_fs: resurect usb_functionfs_descs_head structure

2014-06-27T15:41:29Z

Even though usb_functionfs_descs_head structure is now deprecated, it has been used by some user space tools. Its removel in commit [ac8dde1: “Add flags to descriptors block”] was an oversight leading to build breakage for such tools. Bring it back so that old user space tools can still be build without problems on newer kernel versions.
