2013-03-15Fix dst_neigh_lookup/dst_neigh_lookup_skb return value handling bugZhouyi Zhou
When neighbour table is full, dst_neigh_lookup/dst_neigh_lookup_skb will return -ENOBUFS which is absolutely non zero, while all the code in kernel which use above functions assume failure only on zero return which will cause panic. (for example: : https://bugzilla.kernel.org/show_bug.cgi?id=54731). This patch corrects above error with smallest changes to kernel source code and also correct two return value check missing bugs in drivers/infiniband/hw/cxgb4/cm.c Tested on my x86_64 SMP machine Reported-by: Zhouyi Zhou <zhouzhouyi@gmail.com> Tested-by: Zhouyi Zhou <zhouzhouyi@gmail.com> Signed-off-by: Zhouyi Zhou <zhouzhouyi@gmail.com> Signed-off-by: David S.

2013-03-15net: fec: fix missing napi_disable callGeorg Hofmann
Commit dc975382d2ef36be7e78fac3717927de1a5abcd8 introduces napi support but never calls napi_disable. This will generate a kernel oops (kernel BUG at include/linux/netdevice.h:473!) every time, when ndo_stop is called followed by ndo_start. Add the missing napi_diable call.

2013-03-15net: fec: restart the FEC when PHY speed changesLucas Stach
Proviously we would only restart the FEC when PHY link or duplex state changed. PHY does not always bring down the link for speed changes, in which case we would not detect any change and keep FEC running. Switching link speed without restarting the FEC results in the FEC being stuck in an indefinite state, generating error conditions for every packet.

2013-03-15mfd: twl4030-madc: Remove __exit_p annotationArnd Bergmann
4740f73fe5 "mfd: remove use of __devexit" removed the __devexit annotation on the twl4030_madc_remove function, but left an __exit_p() present on the pointer to this function. Using __exit_p was as wrong with the devexit in place as it is now, but now we get a gcc warning about an unused function. In order for the twl4030_madc_remove to work correctly in built-in code, we have to remove the __exit_p.

ARM normally has an accurate clock source, so we can theoretically use analog joysticks more accurately and at the same time avoid the build warning #warning Precise timer not defined for this architecture. from the joystick driver. Now, why anybody would use that driver no ARM I have no idea, but Ben Dooks enabled it in the s3c2410_defconfig along with a bunch of other drivers, even though that platform has neither ISA nor PCI support.

2013-03-14mtd: nand: reintroduce NAND_NO_READRDY as NAND_NEED_READRDYBrian Norris
This partially reverts commit 1696e6bc2ae83734e64e206ac99766ea19e9a14e ("mtd: nand: kill NAND_NO_READRDY"). In that patch I overlooked a few things. The original documentation for NAND_NO_READRDY included "True for all large page devices, as they do not support autoincrement." I was conflating "not support autoincrement" with the NAND_NO_AUTOINCR option, which was in fact doing nothing. So, when I dropped NAND_NO_AUTOINCR, I concluded that I then could harmlessly drop NAND_NO_READRDY. But of course the fact the NAND_NO_AUTOINCR was doing nothing didn't mean NAND_NO_READRDY was doing nothing... So, NAND_NO_READRDY is re-introduced as NAND_NEED_READRDY and applied only to those few remaining small-page NAND which needed it in the first place.

This resulted in 'tty is NULL' warnings from flush_to_ldisc() when the device was used. The devices use just one read urb for all ports. As a result qt2_process_read_urb() may be called with the current port set to a port number that has not been opened. Add a check if the port is open before calling tty_flip_buffer_push().

2013-03-13net: qmi_wwan: set correct altsetting for Gobi 1K devicesBjørn Mork
commit bd877e4 ("net: qmi_wwan: use a single bind function for all device types") made Gobi 1K devices fail probing. Using the number of endpoints in the default altsetting to decide whether the function use one or two interfaces is wrong. Other altsettings may provide more endpoints. With Gobi 1K devices, USB interface #3's altsetting is 0 by default, but altsetting 0 only provides one interrupt endpoint and is not sufficent for QMI. Altsetting 1 provides all 3 endpoints required for qmi_wwan and works with QMI. Gobi 1K layout for intf#3 is: Interface Descriptor: 255/255/255 bInterfaceNumber 3 bAlternateSetting 0 Endpoint Descriptor: Interrupt IN Interface Descriptor: 255/255/255 bInterfaceNumber 3 bAlternateSetting 1 Endpoint Descriptor: Interrupt IN Endpoint Descriptor: Bulk IN Endpoint Descriptor: Bulk OUT Prior to commit bd877e4, we would call usbnet_get_endpoints before giving up finding enough endpoints. Removing the early endpoint number test and the strict functional descriptor requirement allow qmi_wwan_bind to continue until usbnet_get_endpoints has made the final attempt to collect endpoints. This restores the behaviour from before commit bd877e4 without losing the added benefit of using a single bind function. The driver has always required a CDC Union functional descriptor for two-interface functions. Using the existence of this descriptor to detect two-interface functions is the logically correct method.

2013-03-13tg3: 5715 does not link up when autoneg offNithin Sujir
Commit d13ba512cbba7de5d55d7a3b2aae7d83c8921457 ("tg3: Remove SPEED_UNKNOWN checks") cleaned up the autoneg advertisement by removing some dead code. One effect of this change was that the advertisement register would not be updated if autoneg is turned off. This exposed a bug on the 5715 device w.r.t linking. The 5715 defaults to advertise only 10Mb Full duplex. But with autoneg disabled, it needs the configured speed enabled in the advertisement register to link up. This patch adds the work around to advertise all speeds on the 5715 when autoneg is disabled.

Commit fae50823d0 ("net: ethernet: davinci_cpdma: Add boundary for rx and tx descriptors") introduced a function to check the current allocation state of tx packets. The return value is taken into account to stop the netqork queue on the adapter in case there are no free slots. However, cpdma_check_free_tx_desc() returns 'true' if there is room in the bitmap, not 'false', so the usage of the function is wrong.

I was too lazy to bisect for bad commit;) Reading the code I found problematic kthread_should_stop call from netlink connector which causes the oops. After applying a patch, I've been testing owfs+w1 setup for nearly two days and it seems to work very reliable (no hangs, no memleaks etc). More detailed description and possible fix is given below: Function w1_search can be called from either kthread or netlink callback. While the former works fine, the latter causes oops due to kthread_should_stop invocation. This patch adds a check if w1_search is serving netlink command, skipping kthread_should_stop invocation if so.

Commit 8a1861d997 ("w1-gpio: Simplify & get rid of defines") changed (apparently unknowingly) the driver to a hotpluggable platform-device driver but did not not update the section markers for probe and remove (to __devinit/exit, which have since been removed). A later commit fixed the section mismatch for probe, but left remove marked with __exit.
