* USB: gadget: ethernet error path potential oops fixDavid Brownell2008-02-011-3/+3
| | | | | | | | | | | | Fix potential (never-observed) oops on rare error path, bugzilla #9594. Fix uses the same test as used earlier. Also make the adjacent "else" block look like an "else" block instead of hiding like a bug.

* usb-gadget-ether: prevent oops caused by error interrupt raceBenedikt Spranger2007-10-121-0/+12
| | | | | | | | | | | | | | | | | | | | | | Fix a longstanding race in the Ethernet gadget driver, which can cause an oops on device disconnect. The fix is just to make the TX path check whether its freelist is empty. That check is otherwise not necessary, since the queue is always stopped when that list empties (and restarted when request completion puts an entry back on that freelist). The race window starts when the network code decides to transmit a packet, and ends when hard_start_xmit() grabs the freelist lock. When disconnect() is called inside that window, it shuts down the TX queue and breaks the otherwise-solid assumption that packets are never sent through a TX queue that's stopped.

* USB: gadget: ethernet gadget cleanups, shrinkageDavid Brownell2007-10-121-87/+54
| | | | | | | | | | | | | | | | | | | | | | Clean up the ethernet gadget, using newer APIs and conventions: - gadget_is_dualspeed() and gadget_is_otg() ... #ifdef removal - Remove many now-needless #includes - Use the VERBOSE_DEBUG convention - Minor whitespace fixes. - Fix a warning from "sparse". Surprisingly, this saved about 2K of code (16%) on a fullspeed-only ARMv4 platform. I'm bit puzzled by that (it's so much!), but approve of the result.

* [PATCH] remove many unneeded #includes of sched.hTim Schmielau2007-02-141-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).

* USB: ethernet gadget interop with MCCI Windows driverDavid Brownell2007-02-081-39/+103
| | | | | | | | | | | | | | | | | | It turns out that minor tweaks to the "CDC Subset" support in the Ethernet gadget driver, just updating a config descriptor, let it be automagically recognized by a Windows driver supported by MCCI. This patch adds those descriptors, so systems using PXA 255 processors (like Gumstix etc) can interop with those commercial MS-Windows drivers. This is a Good Thing since Microsoft's RNDIS code has bugginess issues, which are unfortunately compounded by "won't fix" issues as well as "the published specs are incomplete and wrong" issues. Being able to talk to the MCCI driver gives Windows users another connectivity option. (MCCI also has CDC Ethernet drivers, which can help most non-PXA processors.)

* [PATCH] USB: gadget section fixupsDavid Brownell2006-07-131-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | Recent section changes broke gadget builds on some platforms. This patch is the best fix that's available until better section markings exist: - There's a lot of cleanup code that gets used in both init and exit paths; stop marking it as "__exit". (Best fix for this would be an "__init_or_exit" section marking, putting the cleanup in __init when __exit sections get discarded else in __exit.) - Stop marking the use-once probe routines as "__init" since references to those routines are not allowed from driver structures. They're now marked "__devinit", which in practice is a net lose. (Best fix for this is likely to separate such use-once probe routines from the driver structure ... but in general, all busses that aren't hotpluggable will be forced to waste memory for all probe-only code.) In general these broken section rules waste an average of two to four kBytes per driver of code bloat ... because none of the relevant code can ever be reused after module initialization.

The "musbh" standing for "Mentor USB Highspeed", the rest standing for "Function Controller" or "Dual Role Controller" (OTG-capable). - The full speed controller on the FreeScale MPC8272.

* [PATCH] usb gadget: ethernet/rndis updatesDavid Brownell2005-04-191-32/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | Updates to the Ethernet/RNDIS gadget driver (mostly for RNDIS): - Fix brown-paper bag goof with RNDIS packet TX ... the wrong length field got set, so Windows would ignore data packets it received. - More consistent handling of CDC output filters (but not yet hooking things up so RNDIS uses the mechanism). - Zerocopy RX for RNDIS packets too (saving CPU cycles). - Use the pre-allocated interrupt/status request and buffer, rather than allocating and freeing one of each every few seconds (which could fail). - Some more "sparse" tweaks, making both dual-speed and single-speed configurations happier. - RNDIS speeds are reported in units of 100bps, not bps. Plus two minor cleanups (whitespace, messaging). Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
