2010-11-06floppy: fix another use-after-freeVivek Goyal
While scanning the floopy code due to c093ee4f07f4 ("floppy: fix use-after-free in module load failure path"), I found one more instance of trying to access disk->queue pointer after doing put_disk() on gendisk. For some reason , floppy moule still loads/unloads fine. The object is probably still around with right pointer values. o There seems to be one more instance of trying to cleanup the request queue after we have called put_disk() on associated gendisk. o This fix is more out of code inspection. Even without this fix for some reason I am able to load/unload floppy module without any issues. o Floppy module loads/unloads fine after the fix.

2010-11-05ipw2x00: remove the right /proc/net entryLinus Torvalds
Commit 27ae60f8f7aa ("ipw2x00: replace "ieee80211" with "libipw" where appropriate") changed DRV_NAME to be "libipw", but didn't properly fix up the places where it was used to specify the name for the /proc/net/ directory. For backwards compatibility reasons, that directory name remained "ieee80211", but due to the DRV_NAME change, the error case printouts and the cleanup functions now used "libipw" instead. Which made it all fail badly. For example, on module unload as reported by Randy: WARNING: at fs/proc/generic.c:816 remove_proc_entry+0x156/0x35e() name 'libipw' because it's trying to unregister a /proc directory that obviously doesn't even exist. Clean it all up to use DRV_PROCNAME for the actual /proc directory name. Reported-and-tested-by: Randy Dunlap <randy.dunlap@oracle.com> Cc: Pavel Roskin <proski@gnu.org> Cc: John W.

2010-11-05floppy: fix use-after-free in module load failure pathLinus Torvalds
Commit 488211844e0c ("floppy: switch to one queue per drive instead of sharing a queue") introduced a use-after-free. We do "put_disk()" on the disk device _before_ we then clean up the queue associated with that disk. Move the put_disk() down to avoid dereferencing a free'd data structure.

2010-11-05posix-cpu-timers: workaround to suppress the problems with mt execOleg Nesterov
posix-cpu-timers.c correctly assumes that the dying process does posix_cpu_timers_exit_group() and removes all !CPUCLOCK_PERTHREAD timers from signal->cpu_timers list. But, it also assumes that timer->it.cpu.task is always the group leader, and thus the dead ->task means the dead thread group. This is obviously not true after de_thread() changes the leader. After that almost every posix_cpu_timer_ method has problems. It is not simple to fix this bug correctly. First of all, I think that timer->it.cpu should use struct pid instead of task_struct. Also, the locking should be reworked completely. In particular, tasklist_lock should not be used at all. This all needs a lot of nontrivial and hard-to-test changes. Change __exit_signal() to do posix_cpu_timers_exit_group() when the old leader dies during exec. This is not the fix, just the temporary hack to hide the problem for 2.6.37 and stable. IOW, this is obviously wrong but this is what we currently have anyway: cpu timers do not work after mt exec. In theory this change adds another race. The exiting leader can detach the timers which were attached to the new leader. However, the window between de_thread() and release_task() is small, we can pretend that sys_timer_create() was called before de_thread().

It leads to leaking of contents of kernel stack memory. We have to initialize them to zero.

2010-11-05KVM: Write protect memory after slot swapMichael S. Tsirkin
I have observed the following bug trigger: 1. userspace calls GET_DIRTY_LOG 2. kvm_mmu_slot_remove_write_access is called and makes a page ro 3. page fault happens and makes the page writeable fault is logged in the bitmap appropriately 4. kvm_vm_ioctl_get_dirty_log swaps slot pointers a lot of time passes 5. guest writes into the page 6. userspace calls GET_DIRTY_LOG At point (5), bitmap is clean and page is writeable, thus, guest modification of memory is not logged and GET_DIRTY_LOG returns an empty bitmap. The rule is that all pages are either dirty in the current bitmap, or write-protected, which is violated here. It seems that just moving kvm_mmu_slot_remove_write_access down to after the slot pointer swap should fix this bug. KVM-Stable-Tag. Signed-off-by: Michael S.

Split the USB MMR init steps out into a helper func that both the platform init and the resume code may call. Then while suspending, the gpio_vrsel will change from high to low which will generate a wakeup event and resume the system immediately, so we need to manually drive it low before we sleep.

2010-11-05USB: musb: gadget: fix MUSB_TXMAXP and MUSB_RXMAXP configurationMing Lei
Commit 9f445cb29918dc488b7a9a92ef018599cce33df7[USB: musb: disable double buffering for older RTL versions] tries to disable double buffer mode by writing endpoint hw max packet size to TXMAP/RXMAP. First the approach can break full speed and cause overflow problems. We should always set those registers with the actual max packet size from endpoint descriptor. Second, the problem describe by commit 9f445cb29918dc488b7a9a92ef018599cce33df7 was caused by musb gadget driver; nothing to do with RTL revision as originaly suspected. The real fix to the problem is to always use actual max packet size from endpoint descriptor to config TXMAP/RXMAP registers.

2010-11-05usb: musb: don't leave PHY enabled on shutdown()Grazvydas Ignotas
Some actions like musb_platform_exit are only performed on module removal and not on shutdown, which results in PHY being left enabled on reboot at least. This is sometimes causing strange failures after reboot (observed on OMAP3 pandora board), when DEVCTL does not report VBUS state correctly due to unknown reasons (possibly because of communication issues between musb IP and PHY). Running musb_platform_exit before reset seems to resolve that issue. Move some exit code from musb_remove() to musb_shutdown() so that it is performed on both module removal and shutdown/reset. Also convert the host check so that it doesn't need #ifdef. Signed-off-by: Grazvydas Ignotas <notasas@gmail.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
