Based on a patch from Don Howard <dhoward@redhat.com> When calling write() with a buffer larger than 512 bytes, the driver's write buffer overflows, allowing to overwrite the EIP and execute arbitrary code with kernel privileges. In read(), there exists a similar problem, but coming from the device. A malicous or buggy device sending more than 512 bytes can overflow of the driver's read buffer, with the same effects as above.

Suspend deadlocks when trying to unregister /sys/block/sr0. This comes from Oliver's commit 94bebf4d "Driver core: fix race in sysfs between sysfs_remove_file() and read()/write()". sysfs_write_file downs buffer->sem while calling flush_write_buffer, and flushing that particular write buffer entails downing buffer->sem in orphan_all_buffers, resulting in the obvious self-deadlock.

Provide a module param "pool_mode" for sunrpc.ko which allows a sysadmin to choose the mode for mapping NFS thread service pools to CPUs. Values are: auto choose a mapping mode heuristically global (default, same as the pre-2.6.19 code) a single global pool percpu one pool per CPU pernode one pool per NUMA node Note that since 2.6.19 the hardcoded behaviour has been "auto", this patch makes the default "global". The pool mode can be changed after boot/modprobe using /sys, if the NFS and lockd services have been shut down. A useful side effect of this change is to fix a small memory leak when unloading the module. Signed-off-by:

When the last thread of nfsd exits, it shuts down all related sockets. It currently uses svc_close_socket to do this, but that only is immediately effective if the socket is not SK_BUSY. If the socket is busy - i.e. if a request has arrived that has not yet been processes - svc_close_socket is not effective and the shutdown process spins. So create a new svc_force_close_socket which removes the SK_BUSY flag is set and then calls svc_close_socket. Also change some open-codes loops in svc_destroy to use list_for_each_entry_safe.

The sunrpc server code needs to know the source and destination address for UDP packets so it can reply properly. It currently copies code out of the network stack to pick the pieces out of the skb. This is ugly and causes compile problems with the IPv6 stuff. So, rip that out and use recv_msg instead. This is a much cleaner interface, but has a slight cost in that the checksum is now checked before the copy, so we don't benefit from doing both at the same time. This can probably be fixed.

This patch changes the way we determine if a logical volume is larger than 2TB. The original test looked for a total_size of 0. Originally we added 1 to the total_size. That would make our read_capacity return size 0 for >2TB lv's. We assumed that we could not have a lv size of 0 so it seemed OK until we were in a clustered system. The backup node would see a size of 0 due to the reservation on the drive. That caused the driver to switch to 16-byte CDB's which are not supported on older controllers. After that everything was broken. It may seem petty but I don't see the value in trying to determine if the LBA is beyond the 2TB boundary. That's why when we switch we use 16-byte CDB's for all read/write operations. Please consider this for inclusion. Signed-off-by:

rcutorture's module parameters currently use permissions of 0, so they don't show up in /sys/module/rcutorture/parameters. Change the permissions on all module parameters to world-readable (0444). rcutorture does all of its initialization and thread startup when loaded and relies on the parameters not changing during execution, so they should not permit writing. However, reading seems fine. Signed-off-by:

I've only seen this on x86_64. The vsyscall state only gets updated when a timer interrupts comes in. So if the time is set long before the next timer, there will be a period when a gettimeofday() won't reflect the correct time. I added an explicit update_vsyscall() during the settimeofday(), that way the vsyscall state doesn't get stale. Signed-off-by:

The TIMER_SOFTIRQ runs the hrtimers during bootup until a usable clocksource and clock event sources are registered. The switch to high resolution mode happens inside of the TIMER_SOFTIRQ, but runs the softirq afterwards. That way the tick emulation timer, which was set up in the switch to highres might be executed in the softirq context, which is a BUG. The rbtree has not to be touched by the softirq after the highres switch. This BUG was observed by Andres Salomon, who provided the information to debug it. Return early from the softirq, when the switch was sucessful. [dilinger@debian.org: add debug warning] [akpm@linux-foundation.org: make debug warning compile] Signed-off-by:

Prior to commit 95492e46 ([PATCH] x86: rewrite SMP TSC sync code), the headers in asm-i386 did not really require anything in include/asm-x86_64. This means that distributions such as fedora did not include asm-x86_64 in kernel-devel headers for i386. Ingo's commit changed that, and broke things. This is easy enough to hack around in package builds by just including asm-x86_64 on i386, but that's kind of annoying. If anything, x86_64 should depend upon i386, not the other way around. This patch changes it so that asm-x86_64/tsc.h includes asm-i386/tsc.h, rather than vice-versa. Signed-off-by:

Any attempt to open/use a bluetooth rfcomm device locks up scheduling completely on my machine. Interrupts (ping, alt-sysrq) seem to be alive, but nothing else.

The programming of periodic tick devices needs to be saved/restored across suspend/resume - otherwise we might end up with a system coming up that relies on getting a PIT (or HPET) interrupt, while those devices default to 'no interrupts' after powerup. (To confuse things it worked to a certain degree on some systems because the lapic gets initialized as a side-effect of SMP bootup.) This suspend / resume thing was dropped unintentionally during the last-minute -mm code reshuffling. Signed-off-by:

The interrupt is shared with another device, which resumes earlier than the sdhci controller, and generates an interrupt. The sdhci interrupt handler runs, sees 0xffffffff in its own device's interrupt status, and tries to handle it.. The reason for the 0xffffffff is that the device is still suspended, and *all* regs are reading back 0xffffffff. Signed-off-by:
