2009-11-08fsl_pq_mdio: Fix compiler/sparse warnings (part 1)Anton Vorontsov
commit 1d2397d742b7a2b39b2f09dd9da3b9d1463f55e9 ("fsl_pq_mdio: Add Suport for etsec2.0 devices") introduced the following warnings: CHECK fsl_pq_mdio.c fsl_pq_mdio.c:287:22: warning: incorrect type in initializer (different base types) fsl_pq_mdio.c:287:22: expected unknown type 11 const *__mptr fsl_pq_mdio.c:287:22: got unsigned long long [unsigned] [assigned] [usertype] addr fsl_pq_mdio.c:287:19: warning: incorrect type in assignment (different base types) fsl_pq_mdio.c:287:19: expected unsigned long long [unsigned] [usertype] ioremap_miimcfg fsl_pq_mdio.c:287:19: got struct fsl_pq_mdio *<noident> CC fsl_pq_mdio.o fsl_pq_mdio.c: In function 'fsl_pq_mdio_probe': fsl_pq_mdio.c:287: warning: initialization makes pointer from integer without a cast fsl_pq_mdio.c:287: warning: assignment makes integer from pointer without a cast These warnings are not easy to fix without ugly __force casts. So, instead of introducing the casts, rework the code to substitute an offset from an already mapped area. This makes the code a lot simpler and less duplicated. Plus, from now on we don't actually map reserved registers on non-etsec2.0 devices, so we have more chances to catch programming errors.

2009-11-06net, compat_ioctl: handle more ioctls correctlyArnd Bergmann
The MII ioctls and SIOCSIFNAME need to go through ifsioc conversion, which they never did so far. Some others are not implemented in the native path, so we can just return -EINVAL directly.

2009-11-06compat: move sockios handling to net/socket.cArnd Bergmann
This removes the original socket compat_ioctl code from fs/compat_ioctl.c and converts the code from the copy in net/socket.c into a single function. We add a few cycles of runtime to compat_sock_ioctl() with the long switch() statement, but gain some cycles in return by simplifying the call chain to get there.

2009-11-06net, compat_ioctl: handle socket ioctl abuses in tty driversArnd Bergmann
Slip and a few other drivers use the same ioctl numbers on tty devices that are normally meant for sockets. This causes problems with our compat_ioctl handling that tries to convert the data structures in a different format. Fortunately, these five drivers all use 32 bit compatible data structures in the ioctl numbers, so we can just add a trivial compat_ioctl conversion function to each of them. SIOCSIFENCAP and SIOCGIFENCAP do not need to live in fs/compat_ioctl.c after this any more, and they are not used on any sockets. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: David S.

2009-11-06net/tun: handle compat_ioctl directlyArnd Bergmann
The tun driver is the only code in the kernel that operates on a character device with struct ifreq. Change the driver to handle the conversion itself so we can contain the remaining ifreq handling in the socket layer. This also fixes a bug in the handling of invalid ioctl numbers on an unbound tun device. The driver treats this as a TUNSETIFF in native mode, but there is no way for the generic compat_ioctl() function to emulate this behaviour. Possibly the driver was only doing this accidentally anyway, but if any code relies on this misfeature, it now also works in compat mode.

2009-11-06ipip: Fix handling of DF packets when pmtudisc is OFFHerbert Xu
RFC 2003 requires the outer header to have DF set if DF is set on the inner header, even when PMTU discovery is off for the tunnel. Our implementation does exactly that. For this to work properly the IPIP gateway also needs to engate in PMTU when the inner DF bit is set. As otherwise the original host would not be able to carry out its PMTU successfully since part of the path is only visible to the gateway. Unfortunately when the tunnel PMTU discovery setting is off, we do not collect the necessary soft state, resulting in blackholes when the original host tries to perform PMTU discovery. This problem is not reproducible on the IPIP gateway itself as the inner packet usually has skb->local_df set. This is not correctly cleared (an unrelated bug) when the packet passes through the tunnel, which allows fragmentation to occur. For hosts behind the IPIP gateway it is readily visible with a simple ping. This patch fixes the problem by performing PMTU discovery for all packets with the inner DF bit set, regardless of the PMTU discovery setting on the tunnel itself.

2009-11-06mac80211: async station powersave handlingJohannes Berg
Some devices require that all frames to a station are flushed when that station goes into powersave mode before being able to send frames to that station again when it wakes up or polls -- all in order to avoid reordering and too many or too few frames being sent to the station when it polls. Normally, this is the case unless the station goes to sleep and wakes up very quickly again. But in that case, frames for it may be pending on the hardware queues, and thus races could happen in the case of multiple hardware queues used for QoS/WMM. Normally this isn't a problem, but with the iwlwifi mechanism we need to make sure the race doesn't happen. This makes mac80211 able to cope with the race with driver help by a new WLAN_STA_PS_DRIVER per-station flag that can be controlled by the driver and tells mac80211 whether it can transmit frames or not. This flag must be set according to very specific rules outlined in the documentation for the function that controls it. When we buffer new frames for the station, we normally set the TIM bit right away, but while the driver has blocked transmission to that sta we need to avoid that as well since we cannot respond to the station if it wakes up due to the TIM bit. Once the driver unblocks, we can set the TIM bit. Similarly, when the station just wakes up, we need to wait until all other frames are flushed before we can transmit frames to that station, so the same applies here, we need to wait for the driver to give the OK.
