2012-10-26bas_gigaset: fix pre_reset handlingTilman Schmidt1-3/+16
The delayed work function int_in_work() may call usb_reset_device() and thus, indirectly, the driver's pre_reset method. Trying to cancel the work synchronously in that situation would deadlock. Fix by avoiding cancel_work_sync() in the pre_reset method. If the reset was NOT initiated by int_in_work() this might cause int_in_work() to run after the post_reset method, with urb_int_in already resubmitted, so handle that case gracefully.

When using a 36 bit dtb file, the driver complains "resource busy". Investigating the source of the message leads one to the gianfar_ptp_probe function. Since the type of the device resource requested in this function is IORESOURCE_MEM, it should use "iomem_resource" instead of "ioports_resource".

2012-10-23tcp: Reject invalid ack_seq to Fast Open socketsJerry Chu2-4/+12
A packet with an invalid ack_seq may cause a TCP Fast Open socket to switch to the unexpected TCP_CLOSING state, triggering a BUG_ON kernel panic. When a FIN packet with an invalid ack_seq# arrives at a socket in the TCP_FIN_WAIT1 state, rather than discarding the packet, the current code will accept the FIN, causing state transition to TCP_CLOSING. This may be a small deviation from RFC793, which seems to say that the packet should be dropped. Unfortunately I did not expect this case for Fast Open hence it will trigger a BUG_ON panic. It turns out there is really nothing bad about a TFO socket going into TCP_CLOSING state so I could just remove the BUG_ON statements. But after some thought I think it's better to treat this case like TCP_SYN_RECV and return a RST to the confused peer who caused the unacceptable ack_seq to be generated in the first place.

2012-10-23pch_gbe: don't reset MAC_RX on FIFO overflowVeaceslav Falico1-60/+6
Currently, when FIFO_ERR happens, we stop the dma, wait for it to become idle and then reset the whole MAC_RX logic (and after that we must re-set multicast addresses and also re-enable MAC_RX when we're finally ready to accept new packets). This leads to CRC errors on high number of incoming packets and is not needed according to the datasheet. This patch fixes it by the following steps: 1) remove this reset in pch_gbe_stop_receive(), which causes some functions to not be used anywhere 2) remove already unused functions pch_gbe_wait_clr_bit_irq() and pch_gbe_mac_reset_rx() to correctly build 3) move pch_gbe_enable_mac_rx() out of pch_gbe_start_receive() to pch_gbe_up() where it's only needed after we've removed the MAC_RX reset 4) rename pch_gbe_start/stop_receive() to pch_gbe_enable/disable_dma_rx() to more precisely reflect what the functions are now doing. After these changes we already don't see the CRC errors and gain some increase in RX processing speed. Signed-off-by: Veaceslav Falico <[email protected]> Signed-off-by: David S.

If we were in RX_FIFO_ERR state and entered pch_gbe_napi_poll(), we'll anyway clean some rx space and thus can continue to receive more packets. Currently, we re-set the RX_FIFO_ERR in situations when we've exhausted our budget for RX cleaning or cleaned some TX packets. Removing it gives us +20%-40% speed increase and a lot less of RX_FIFO_ERRors reported. Signed-off-by: Veaceslav Falico <[email protected]> Signed-off-by: David S. Miller <[email protected]>

Mike Kazantsev found 3.5 kernels and beyond were leaking memory, and tracked the faulty commit to a1c7fff7e18f59e ("net: netdev_alloc_skb() use build_skb()") While this commit seems fine, it uncovered a bug introduced in commit bad43ca8325 ("net: introduce skb_try_coalesce()), in function kfree_skb_partial()"): If head is stolen, we free the sk_buff, without removing references on secpath (skb->sp). So IPsec + IP defrag/reassembly (using skb coalescing), or TCP coalescing could leak secpath objects.

On some suspend/resume operations involving wimax device, we have noticed some intermittent memory corruptions in netlink code.

It appears netlink_release() should use kfree_rcu() instead of kfree() for the listeners structure as it may be used by other cpus using RCU protection. netlink_release() must set to NULL the listeners pointer when it is about to be freed.

git://git.infradead.org/users/dhowells/linux-headers Pull misc UAPI fixes from David Howells: "They do a number of things: (1) Import a patch from Catalin Marinas to extend the generic-y in Kbuild facility to uapi directories. (2) Make arch/tile's ucontext.h file use (1) and remove the header-y line from the kernel internal side of things. (3) Remove some now-empty conditional bits from include/linux/Kbuild. The contents got moved to the UAPI side of things along with new conditionals. (4) Deal with now-empty files: (a) Empty Kbuild files under include/ get removed. (b) Empty Kbuild files under arch/ get comments to hold them as they are likely to end up with generic-y or genhdr-y lines. Deleting them appears to work if we want to go that route. (c) Put a comment into uapi/asm-generic/kvm_para.h to prevent the patch program from deleting that, and made the arches with empty kvm_para.h uapi files use that instead of having their own files. (d) Put comments into four other empty uapi/ headers to prevent the patch program from deleting them. A question: Is this the right way to deal with the now-empty Kbuild files?

2012-10-17mac80211: connect with HT20 if HT40 is not permittedJohannes Berg1-10/+20
Some changes to fix issues with HT40 APs in Korea and follow-up changes to allow using HT40 even if the local regulatory database disallows it caused issues with iwlwifi (and could cause issues with other devices); iwlwifi firmware would assert if you tried to connect to an AP that has an invalid configuration (e.g. using HT40- on channel 140.) Fix this, while avoiding the "Korean AP" issue by disabling HT40 and advertising HT20 to the AP when connecting.

arch/sparc/include/uapi/asm/sigcontext.h was emitted by the UAPI disintegration script as an empty file because the parent file had no UAPI stuff in it, despite being marked with "header-y".

2012-10-17UAPI: Put a comment into uapi/asm-generic/kvm_para.h and use it from archesDavid Howells5-0/+8
Make uapi/asm-generic/kvm_para.h non-empty by addition of a comment to stop the patch program from deleting it when it creates it. Then delete empty arch-specific uapi/asm/kvm_para.h files and tell the Kbuild files to use the generic instead. Should this perhaps instead be a #warning or #error that the facility is unsupported on this arch?

2012-10-17UAPI: Place comments in empty arch Kbuilds to make them non-emptyDavid Howells2-0/+2
Place comments in: arch/mips/include/asm/Kbuild arch/tile/include/arch/Kbuild to make them non-empty so that the patch program doesn't remove them when it reduces them to nothing. Possibly they should be just deleted, but it's possible that they'll acquire generic-y or genhdr-y lines in future, so I'm keeping them around for the moment. Note that MIPS will compile happily if the file is deleted instead. I haven't tested TILE, but I suspect it will be the same there.

2012-10-17UAPI: Remove empty non-UAPI Kbuild filesDavid Howells23-21/+0
Remove non-UAPI Kbuild files that have become empty as a result of UAPI disintegration. They used to have only header-y lines in them and those have now moved to the Kbuild files in the corresponding uapi/ directories. Possibly these should not be removed but rather have a comment inserted to say they are intentionally left blank. This would make it easier to add generated header lines in future without having to restore the infrastructure. Note that at this point not all the UAPI disintegration parts have been merged, so it is likely that more empty Kbuild files will turn up. It is probably necessary to make the files non-empty to prevent the patch program from automatically deleting them when it reduces them to nothing. Signed-off-by: David Howells <[email protected]>

2012-10-17UAPI: Make uapi/linux/irqnr.h non-emptyDavid Howells1-0/+4
uapi/linux/irqnr.h was emitted by the UAPI disintegration script as an empty file because the parent linux/irqnr.h had no UAPI stuff in it, despite being marked with "header-y". Unfortunately, the patch program deletes the empty file when applying a kernel patch. It's not clear why this file is part of the UAPI at all. Looking in: /usr/include/linux/irqnr.h there's nothing there but a header reinclusion guard and a comment. So just stick a comment in there as a placeholder. Without this, if the kernel is fabricated from, say, a tarball and a patch, you can get this error when building x86_64 or usermode Linux (and probably others): include/linux/irqnr.h:4:30: fatal error: uapi/linux/irqnr.h: No such file or directory Reported-by: Randy Dunlap <[email protected]> Reported-by: Alessandro Suardi <[email protected]> Signed-off-by: David Howells <[email protected]> cc: Randy Dunlap <[email protected]> cc: Alessandro Suardi <[email protected]>

2012-10-17netfilter: xt_TEE: don't use destination address found in headerEric Dumazet1-0/+1
Torsten Luettgert bisected TEE regression starting with commit f8126f1d5136be1 (ipv4: Adjust semantics of rt->rt_gateway.) The problem is that it tries to ARP-lookup the original destination address of the forwarded packet, not the address of the gateway. Fix this using FLOWI_FLAG_KNOWN_NH Julian added in commit c92b96553a80c1 (ipv4: Add FLOWI_FLAG_KNOWN_NH), so that known nexthop (info->gw.ip) has preference on resolving.
