由 Arnd Bergmann 提交于
The documentation for the USB ethernet devices suggests that only some devices are supposed to use usb0 as the network interface name instead of eth0. The logic used there, and documented in Kconfig for CDC is that eth0 will be used when the mac address is a globally assigned one, but usb0 is used for the locally managed range that is typically used on point-to-point links. Unfortunately, this has caused a lot of pain on the smsc95xx device that is used on the popular pandaboard without an EEPROM to store the MAC address, which causes the driver to call random_ether_address(). Obviously, there should be a proper MAC addressed assigned to the device, and discussions are ongoing about how to solve this, but this patch at least makes sure that the default interface naming gets a little saner and matches what the user can expect based on the documentation, including for new devices. The approach taken here is to flag whether a device might be a point-to-point link with the new FLAG_POINTTOPOINT setting in the usbnet driver_info. A driver can set both FLAG_POINTTOPOINT and FLAG_ETHER if it is not sure (e.g. cdc_ether), or just one of the two. The usbnet framework only looks at the MAC address for device naming if both flags are set, otherwise it trusts the flag.

This adds a driver for the CDC Ethernet part of this modem. The device's ID is blacklisted in cdc_ether.c and is white-listed in this new driver because of the quirks needed to make it useful. The modem's firmware exposes a CDC ACM port for modem control and a CDC Ethernet port for network data. The descriptors look fine but both ports actually are some sort of multiplexers requiring non- standard headers added/removed from every packet or they get ignored. All information is based on a usb traffic log from a Windows machine. On the Verizon 4G network I've seen speeds up to 1.1MB/s so far with this driver, a speed-o-meter site reports 16.2Mbps/10.5Mbps. Userspace scripts are required to talk to the CDC ACM port. Signed-off-by: NAndrzej Zaborowski <balrogg@gmail.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

flush_scheduled_work() is on its way out. This patch contains simple conversions to replace flush_scheduled_work() usage with direct cancels and flushes. Directly cancel the used works on driver detach and flush them in other cases. The conversions are mostly straight forward and the only dangers are, * Forgetting to cancel/flush one or more used works. * Cancelling when a work should be flushed (ie. the work must be executed once scheduled whether the driver is detaching or not). I've gone over the changes multiple times but it would be much appreciated if you can review with the above points in mind. Signed-off-by: NTejun Heo <tj@kernel.org> Cc: "David S.

This patch makes rx_submit() return an error code, and makes some call sites that care check the return value. This is important because it lets us properly handle cases where the device isn't ready to handle URB submissions (e.g., when it is autosuspended under some drivers); previously, we would attempt and fail to submit URBs and reschedule ourselves to try and fail again.

This patch adds setting of the urb transfer flag URB_ZERO_PACKET before submitting an urb for drivers that have requested it (by advertising flag FLAG_SEND_ZLP). The modification is in usbnet.c function usbnet_start_xmit(). This patch only adds the zero length flag. A subsequent patch will address the buggy code we found when devices do not advertise FLAG_SEND_ZLP in which case there is a possibility of transferring packets with non-deterministic length. This patch has been tested on kernel-2.6.34-rc3. This patch has been checked against net-2.6 tree.

include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

Usbnet framework assumes USB hardware doesn't handle zero length packets, but SMSC LAN95xx requires these to be sent for correct operation. This patch fixes an easily reproducible tx lockup when sending a frame that results in exactly 512 bytes in a USB transmission (e.g. a UDP frame with 458 data bytes, due to IP headers and our USB headers).
