bd00c60 David Woodhouse 09 June 2015, 14:06:55 UTC iommu/vt-d: Change PASID support to bit 40 of Extended Capability Register The existing hardware implementations with PASID support advertised in bit 28? Forget them. They do not exist. Bit 28 means nothing. When we have something that works, it'll use bit 40. Do not attempt to infer anything meaningful from bit 28. This will be reflected in an updated VT-d spec in the extremely near future. Signed-off-by: David Woodhouse <David.Woodhouse@intel.com> 09 June 2015, 14:06:55 UTC

d7b6314 Markos Chandras 29 May 2015, 13:43:52 UTC MIPS: pgtable-bits: Fix XPA damage to R6 definitions. Commit be0c37c985ed ("MIPS: Rearrange PTE bits into fixed positions.") rearranged the PTE bits into fixed positions in preparation for the XPA support. However, this patch broke R6 since it only took R2 cores into consideration for the RI/XI bits leading to boot failures. We fix this by adding the missing CONFIG_CPU_MIPSR6 definitions Fixes: be0c37c985ed ("MIPS: Rearrange PTE bits into fixed positions.") Cc: Steven J.

3f5f155 Jani Nikula 02 June 2015, 16:21:15 UTC drm/i915: Fix DDC probe for passive adapters Passive DP->DVI/HDMI dongles on DP++ ports show up to the system as HDMI devices, as they do not have a sink device in them to respond to any AUX traffic. When probing these dongles over the DDC, sometimes they will NAK the first attempt even though the transaction is valid and they support the DDC protocol. The retry loop inside of drm_do_probe_ddc_edid() would normally catch this case and try the transaction again, resulting in success. That, however, was thwarted by the fix for [1]: commit 9292f37e1f5c79400254dca46f83313488093825 Author: Eugeni Dodonov <eugeni.dodonov@intel.com> Date: Thu Jan 5 09:34:28 2012 -0200 drm: give up on edid retries when i2c bus is not responding This added code to exit immediately if the return code from the i2c_transfer function was -ENXIO in order to reduce the amount of time spent in waiting for unresponsive or disconnected devices. That was possible because the underlying i2c bit banging algorithm had retries of its own (which, of course, were part of the reason for the bug the commit fixes). Since its introduction in commit f899fc64cda8569d0529452aafc0da31c042df2e Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Tue Jul 20 15:44:45 2010 -0700 drm/i915: use GMBUS to manage i2c links we've been flipping back and forth enabling the GMBUS transfers, but we've settled since then. The GMBUS implementation does not do any retries, however, bailing out of the drm_do_probe_ddc_edid() retry loop on first encounter of -ENXIO. This, combined with Eugeni's commit, broke the retry on -ENXIO. Retry GMBUS once on -ENXIO on first message to mitigate the issues with passive adapters. This patch is based on the work, and commit message, by Todd Previte <tprevite@gmail.com>. [1] https://bugs.freedesktop.org/show_bug.cgi?id=41059 v2: Don't retry if using bit banging. v3: Move retry within gmbux_xfer, retry only on first message. v4: Initialize GMBUS0 on retry (Ville). v5: Take index reads into account (Ville).

After we posted the last wr in isert_wait_conn we are guaranteed that no successful completions will follow (meaning no new work request posts may happen) but other flush errors might still come. So before we put the last reference on the connection, we repeat the process of posting a marked work request (isert_wait4flush) in order to make sure all pending completions were flushed.

2f1b6b7 Sagi Grimberg 04 June 2015, 16:49:20 UTC iser-target: release stale iser connections When receiving a new iser connect request we serialize the pending requests by adding the newly created iser connection to the np accept list and let the login thread process the connect request one by one (np_accept_wait). In case we received a disconnect request before the iser_conn has begun processing (still linked in np_accept_list) we should detach it from the list and clean it up and not have the login thread process a stale connection. We do it only when the connection state is not already terminating (initiator driven disconnect) as this might lead us to access np_accept_mutex after the np was released in live shutdown scenarios.

Given that we rely on cmd t_data_nents which might be different than the data_size, we sometimes receive local length error completion. The correct approach would be to take the command data_size into account when constructing the ib sg_list.

0243508 Josh Hunt 08 June 2015, 16:00:59 UTC ipv6: Fix protocol resubmission UDP encapsulation is broken on IPv6. This is because the logic to resubmit the nexthdr is inverted, checking for a ret value > 0 instead of < 0. Also, the resubmit label is in the wrong position since we already get the nexthdr value when performing decapsulation. In addition the skb pull is no longer necessary either. This changes the return value check to look for < 0, using it for the nexthdr on the next iteration, and moves the resubmit label to the proper location. With these changes the v6 code now matches what we do in the v4 ip input code wrt resubmitting when decapsulating.

For example, through IP6_*_STATS_* calls in ip6_rcv. These memory blocks are freed without waiting for an RCU grace period to elapse. This could lead to the memory being written to after it has been freed. Fix this by using call_rcu to free the memory used for stats, as well as idev after an RCU grace period has elapsed.

c4c832f Nikolay Aleksandrov 06 June 2015, 13:49:00 UTC bridge: disable softirqs around br_fdb_update to avoid lockup br_fdb_update() can be called in process context in the following way: br_fdb_add() -> __br_fdb_add() -> br_fdb_update() (if NTF_USE flag is set) so we need to disable softirqs because there are softirq users of the hash_lock. One easy way to reproduce this is to modify the bridge utility to set NTF_USE, enable stp and then set maxageing to a low value so br_fdb_cleanup() is called frequently and then just add new entries in a loop. This happens because br_fdb_cleanup() is called from timer/softirq context. The spin locks in br_fdb_update were _bh before commit f8ae737deea1 ("[BRIDGE]: forwarding remove unneeded preempt and bh diasables") and at the time that commit was correct because br_fdb_update() couldn't be called from process context, but that changed after commit: 292d1398983f ("bridge: add NTF_USE support") Using local_bh_disable/enable around br_fdb_update() allows us to keep using the spin_lock/unlock in br_fdb_update for the fast-path.

Therefore it can happen that we find a class of which ->name/->key are no longer valid. There is a further bug in zap_class() that left ->name dangling. Cure this. Use RCU_INIT_POINTER() because NULL. Since lockdep_free_key_range() is rcu_sched serialized, we can read both ->name and ->key under rcu_read_lock_sched() (preempt-disable) and be assured that if we observe a !NULL value it stays safe to use for as long as we hold that lock.

Next fixes a bug in the default configuration which prevented a software bridge loaded on the PF interface from working correctly because broadcast packets are incorrectly looped back.

e6050b6 Chris Leech 28 May 2015, 19:51:51 UTC iscsi_ibft: filter null v4-mapped v6 addresses I've had reports of UEFI platforms failing iSCSI boot in various configurations, that ended up being caused by network initialization scripts getting tripped up by unexpected null addresses (0.0.0.0) being reported for gateways, dhcp servers, and dns servers. The tianocore EDK2 iSCSI driver generates an iBFT table that always uses IPv4-mapped IPv6 addresses for the NIC structure fields. This results in values that are "not present or not specified" being reported as ::ffff:0.0.0.0 rather than all zeros as specified. The iscsi_ibft module filters unspecified fields from the iBFT from sysfs, preventing userspace from using invalid values and making it easy to check for the presence of a value. This currently fails in regard to these mapped null addresses. In order to remain consistent with how the iBFT information is exposed, we should accommodate the behavior of the tianocore iSCSI driver as it's already in the wild in a large number of servers. Tested under qemu using an OVMF build of tianocore EDK2.

38d8571 Russell King 05 June 2015, 22:27:30 UTC drm: fix writing to /sys/class/drm/*/status Writing to a file is supposed to return the number of bytes written. Returning zero unfortunately causes bash to constantly spin trying to write to the sysfs file, to such an extent that even ^c and ^z have no effect. The only way out of that is to kill the shell and log back in. This isn't nice behaviour. Fix it by returning the number of characters written to sysfs files.

And even for v7 devices where this does not lead to making the trackstick entirely unusable, it makes it twice as slow as before we added v7 support and were using the ps/2 mouse emulation of the dual point setup. If some kind of generic slowdown is actually necessary for some devices, then that belongs in userspace, not in the kernel.

fc60861 Anjali Singhai Jain 08 May 2015, 22:35:57 UTC i40e: start up in VEPA mode by default The patch fixes a bug in the default configuration which prevented a software bridge loaded on the PF interface from working correctly because broadcast packets are incorrectly looped back. Fix the general case, by loading the driver in VEPA mode Until a VF or VMDq VSI is added. This way loopback on the Main VSI is turned off until needed and can resolve the issue of unnecessary reflection for users that do not have VF or VMDq VSIs setup. The driver must now coordinate the loopback setting for the Flow Director (FDIR) VSI to make sure it is in sync with the current VEB or VEPA mode setting. The user can still switch bridge modes from the bridge commands and choose to be in VEPA mode with VF VSIs. Because of hardware requirements, the call to switch to VEB mode when no VF/VMDqs are present will be rejected. NOTE: This patch uses BIT_ULL as that is preferred going forward, a followup patch in the lower priority queue to net-next will fix up the remaining 1 << usages.

9b7b819 Helge Deller 04 June 2015, 21:57:18 UTC compat: cleanup coding in compat_get_bitmap() and compat_put_bitmap() In the functions compat_get_bitmap() and compat_put_bitmap() the variable nr_compat_longs stores how many compat_ulong_t words should be copied in a loop. The copy loop itself is this: if (nr_compat_longs-- > 0) { if (__get_user(um, umask)) return -EFAULT; } else { um = 0; } Since nr_compat_longs gets unconditionally decremented in each loop and since it's type is unsigned this could theoretically lead to out of bounds accesses to userspace if nr_compat_longs wraps around to (unsigned)(-1). Although the callers currently do not trigger out-of-bounds accesses, we should better implement the loop in a safe way to completely avoid such warp-arounds.

ea114fc Clemens Ladisch 03 June 2015, 09:36:51 UTC ALSA: usb-audio: fix missing input volume controls in MAYA44 USB(+) The driver worked around an error in the MAYA44 USB(+)'s mixer unit descriptor by aborting before parsing the missing field. However, aborting parsing too early prevented parsing of the other units connected to this unit, so the capture mixer controls would be missing. Fix this by moving the check for this descriptor error after the parsing of the unit's input pins.

161f873 Sasha Levin 28 January 2015, 20:30:43 UTC vfs: read file_handle only once in handle_to_path We used to read file_handle twice. Once to get the amount of extra bytes, and once to fetch the entire structure. This may be problematic since we do size verifications only after the first read, so if the number of extra bytes changes in userspace between the first and second calls, we'll have an incoherent view of file_handle. Instead, read the constant size once, and copy that over to the final structure without having to re-read it again.
