2006-05-10[NET]: Do sysfs registration as part of register_netdevice.Stephen Hemminger
The last step of netdevice registration was being done by a delayed call, but because it was delayed, it was impossible to return any error code if the class_device registration failed. Side effects: * one state in registration process is unnecessary. * register_netdevice can sleep inside class_device registration/hotplug * code in netdev_run_todo only does unregistration so it is simpler.

2006-05-08[PATCH] x86_64: Avoid EBDA area in early boot allocatorAndi Kleen
Based on analysis&patch from Robert Hentosch Observed on a Dell PE6850 with 16GB The problem occurs very early on, when the kernel allocates space for the temporary memory map called bootmap. The bootmap overlaps the EBDA region. EBDA region is not historically reserved in the e820 mapping. When the bootmap is freed it marks the EBDA region as usable. If you notice in setup.c there is already code to work around the EBDA in reserve_ebda_region(), this check however occurs after the bootmap is allocated and doesn't prevent the bootmap from using this range. AK: I redid the original patch. Thanks also to Jan Beulich for spotting some mistakes.

2006-05-08[PATCH] x86_64: avoid IRQ0 ioapic pin collisionKimball Murray
The patch addresses a problem with ACPI SCI interrupt entry, which gets re-used, and the IRQ is assigned to another unrelated device. The patch corrects the code such that SCI IRQ is skipped and duplicate entry is avoided. Second issue came up with VIA chipset, the problem was caused by original patch assigning IRQs starting 16 and up. The VIA chipset uses 4-bit IRQ register for internal interrupt routing, and therefore cannot handle IRQ numbers assigned to its devices. The patch corrects this problem by allowing PCI IRQs below 16.

2006-05-05[PATCH] softmac: make non-operational after being stoppedDaniel Drake
zd1211 with softmac and wpa_supplicant revealed an issue with softmac and the use of workqueues. Some of the work functions actually reschedule themselves, so this meant that there could still be pending work after flush_scheduled_work() had been called during ieee80211softmac_stop(). This patch introduces a "running" flag which is used to ensure that rescheduling does not happen in this situation. I also used this flag to ensure that softmac's hooks into ieee80211 are non-operational once the stop operation has been started. This simply makes softmac a little more robust, because I could crash it easily by receiving frames in the short timeframe after shutting down softmac and before turning off the ZD1211 radio.

2006-05-03powerpc: Fix incorrect might_sleep in __get_user/__put_user on kernel addressesPaul Mackerras
We have a case where __get_user and __put_user can validly be used on kernel addresses in interrupt context - namely, the alignment exception handler, as our get/put_unaligned just do a single access and rely on the alignment exception handler to fix things up in the rare cases where the cpu can't handle it in hardware. Thus we can get alignment exceptions in the network stack at interrupt level. The alignment exception handler does a __get_user to read the instruction and blows up in might_sleep(). Since a __get_user on a kernel address won't actually ever sleep, this makes the might_sleep conditional on the address being less than PAGE_OFFSET. Signed-off-by: Paul Mackerras <paulus@samba.org>

2006-05-01[NETFILTER] x_tables: fix compat related crash on non-x86Patrick McHardy
When iptables userspace adds an ipt_standard_target, it calculates the size of the entire entry as: sizeof(struct ipt_entry) + XT_ALIGN(sizeof(struct ipt_standard_target)) ipt_standard_target looks like this: struct xt_standard_target { struct xt_entry_target target; int verdict; }; xt_entry_target contains a pointer, so when compiled for 64 bit the structure gets an extra 4 byte of padding at the end. On 32 bit architectures where iptables aligns to 8 byte it will also have 4 byte padding at the end because it is only 36 bytes large. The compat_ipt_standard_fn in the kernel adjusts the offsets by sizeof(struct ipt_standard_target) - sizeof(struct compat_ipt_standard_target), which will always result in 4, even if the structure from userspace was already padded to a multiple of 8. On x86 this works out by accident because userspace only aligns to 4, on all other architectures this is broken and causes incorrect adjustments to the size and following offsets.
