2010-07-01drm/radeon/kms: Force HDP_NONSURF to maximum sizeJerome Glisse
HDP non surface should cover the whole VRAM but we were misscomputing the size and we endup in some case not covering the VRAM at all (if VRAM size were > 1G). Covering more than the VRAM size shouldn't be an issue.

2010-06-30futex: futex_find_get_task remove credentails checkMichal Hocko
futex_find_get_task is currently used (through lookup_pi_state) from two contexts, futex_requeue and futex_lock_pi_atomic. None of the paths looks it needs the credentials check, though. Different (e)uids shouldn't matter at all because the only thing that is important for shared futex is the accessibility of the shared memory. The credentail check results in glibc assert failure or process hang (if glibc is compiled without assert support) for shared robust pthread mutex with priority inheritance if a process tries to lock already held lock owned by a process with a different euid: pthread_mutex_lock.c:312: __pthread_mutex_lock_full: Assertion `(-(e)) != 3 || !robust' failed. The problem is that futex_lock_pi_atomic which is called when we try to lock already held lock checks the current holder (tid is stored in the futex value) to get the PI state. It uses lookup_pi_state which in turn gets task struct from futex_find_get_task. ESRCH is returned either when the task is not found or if credentials check fails. futex_lock_pi_atomic simply returns if it gets ESRCH. glibc code, however, doesn't expect that robust lock returns with ESRCH because it should get either success or owner died.

2010-06-30bonding: check if clients MAC addr has changedFlavio Leitner
When two systems using bonding devices in adaptive load balancing (ALB) communicates with each other, an endless ping-pong of ARP replies starts between these two systems. What happens? In the ALB mode, bonding driver keeps track of each client connected in a hash table, so it can do the receive load balancing (RLB). This hash table is updated when an ARP reply is received, then it scans for the client entry, updates its MAC address and flag it to be announced later. Therefore, two seconds later, the alb monitor runs and send for each updated client entry two ARP replies updating this specific client. The same process happens on the receiving system, causing the endless ping-pong of arp replies. See more information including the relevant functions below: System 1 System 2 bond0 bond0 ping <system2> ARP request ---------> <--------- ARP reply +->rlb_arp_recv <---------------------+ <--- loop begins | rlb_update_entry_from_arp | | client_info->ntt = 1; | | bond_info->rx_ntt = 1; | | | | <communication succeed> | | | | bond_alb_monitor | | rlb_update_rx_clients | | rlb_update_client | | arp_create(ARPOP_REPLY) | | send ARP reply --------------> V | send ARP reply --------------> | rlb_arp_recv | rlb_update_entry_from_arp | client_info->ntt = 1; | bond_info->rx_ntt = 1; | < snipped, same as in system 1> +------- <-------------- send ARP reply <-------------- send ARP reply Besides the unneeded networking traffic, this loop breaks a cluster because a backup system can't take over the IP address. There is always one system sending an ARP reply poisoning the network. This patch fixes the problem adding a check for the MAC address before updating it. Thus, if the MAC address didn't change, there is no need to update neither to announce it later.

2010-06-30Staging: comedi: drivers: adl_pci9111: Fix AI commands in TRIG_FOLLOW caseIan Abbott
I received a report that AI streaming acquisitions do not work properly for the adl_pci9111 driver when convert_src is TRIG_TIMER and scan_begin_src is TRIG_FOLLOW (and scan_begin_arg is therefore 0). This seems to be down to the incorrect setting of dev_private->scan_delay in pci9111_ai_do_cmd(). Under the previously stated conditions, dev_private->scan_delay ends up set to (unsigned int)-1, but it ought to be set to 0. The function sets it to 0 initially, and it only makes sense to change it if both convert_src and scan_begin_src are set to TRIG_TIMER. Note: 'scan_delay' is the number of unwanted scans to discard after each valid scan. The hardware does not support 'scan' timing as such, just a regularly paced conversion timer (with automatic channel switching between conversions). The driver simulates a scan period that is some (>1) multiple of the conversion period times the scan length (chanlist_len samples) by reading chanlist_len samples and discarding the next scan_delay times chanlist_len samples.

2010-06-30USB: gadget: f_mass_storage: stale common->fsg value bug fixMichal Nazarewicz
On fsg_unbind the common->fsg pointer was not NULLed if the unbound fsg_dev instance was the current one. As an effect, the incorrect pointer was preserved in all further operations which caused do_set_interface to reference an invalid region. This commit fixes this by raising an exception in fsg_bind which will change the common->fsg pointer. This also requires an wait queue so that the thread in fsg_bind can wait till the worker thread handles the exception. This commit removes also a config and new_config fields of fsg_common as they are no longer needed since fsg can be used to determine whether function is active or not. Moreover, this commit removes possible race condition where the fsg field was modified in both the worker thread and form various other contexts. This is fixed by replacing prev_fsg with new_fsg. At this point, fsg is assigned only in worker thread.

2010-06-30USB: MUSB: make non-OMAP platforms build with CONFIG_PM=ySergei Shtylyov
Attempt to build MUSB driver with CONFIG_PM=y (e.g. in the OTG mode) on DaVinci results in these link errors: drivers/built-in.o: In function `musb_restore_context': led-triggers.c:(.text+0x714d8): undefined reference to `musb_platform_restore_context' drivers/built-in.o: In function `musb_save_context': led-triggers.c:(.text+0x71788): undefined reference to `musb_platform_save_context' This turned out to be caused by commit 9957dd97ec5e98dd334f87ade1d9a0b24d1f86eb (usb: musb: Fix compile error for omaps for musb_hdrc). Revert it, taking into account the rename of CONFIG_ARCH_OMAP34XX into CONFIG_ARCH_OMAP3 (which that commit fixed in a completely inappropriate way) and the recent addition of OMAP4 support.

2010-06-30USB: musb_core: make disconnect and suspend interrupts work againSergei Shtylyov
Commit 1c25fda4a09e8229800979986ef399401053b46e (usb: musb: handle irqs in the order dictated by programming guide) forgot to get rid of the old 'STAGE0_MASK' filter for calling musb_stage0_irq(), so now disconnect and suspend interrupts are effectively ignored...

2010-06-30USB: obey the sysfs power/wakeup settingAlan Stern
This patch (as1403) is a partial reversion of an earlier change (commit 5f677f1d45b2bf08085bbba7394392dfa586fa8e "USB: fix remote wakeup settings during system sleep"). After hearing from a user, I realized that remote wakeup should be enabled during system sleep whenever userspace allows it, and not only if a driver requests it too. Indeed, there could be a device with no driver, that does nothing but generate a wakeup request when the user presses a button. Such a device should be allowed to do its job. The problem fixed by the earlier patch -- device generating a wakeup request for no reason, causing system suspend to abort -- was also addressed by a later patch ("USB: don't enable remote wakeup by default", accepted but not yet merged into mainline). The device won't be able to generate the bogus wakeup requests because it will be disabled for remote wakeup by default. Hence this reversion will not re-introduce any old problems.

CRC should be calculated for Ethernet frame, not for whole recievede EEM data. This bug shows rarely, because in many times len == skb->len. Signed-off-by: Jiri Pinkava <jiri.pinkava@vscht.cz> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
