commit 62e96cf8 upstream. This patch calls get_write_access in function gfs2_setattr_chown, which merely increases inode->i_writecount for the duration of the function. That will ensure that any file closes won't delete the inode's multi-block reservation while the function is running. It also ensures that a multi-block reservation exists when needed for quota change operations during the chown. Signed-off-by:

commit bee09ed9 upstream. On AMD family 10h we see following error messages while waking up from S3 for all non-boot CPUs leading to a failed IBS initialization: Enabling non-boot CPUs ... smpboot: Booting Node 0 Processor 1 APIC 0x1 [Firmware Bug]: cpu 1, try to use APIC500 (LVT offset 0) for vector 0x400, but the register is already in use for vector 0xf9 on another cpu perf: IBS APIC setup failed on cpu #1 process: Switch to broadcast mode on CPU1 CPU1 is up ... ACPI: Waking up from system sleep state S3 Reason for this is that during suspend the LVT offset for the IBS vector gets lost and needs to be reinialized while resuming. The offset is read from the IBSCTL msr. On family 10h the offset needs to be 1 as offset 0 is used for the MCE threshold interrupt, but firmware assings it for IBS to 0 too. The kernel needs to reprogram the vector. The msr is a readonly node msr, but a new value can be written via pci config space access. The reinitialization is implemented for family 10h in setup_ibs_ctl() which is forced during IBS setup. This patch fixes IBS setup after waking up from S3 by adding resume/supend hooks for the boot cpu which does the offset reinitialization. Marking it as stable to let distros pick up this fix.

commit 0ac9b1c2 upstream. Currently, group entity load-weights are initialized to zero. This admits some races with respect to the first time they are re-weighted in earlty use. ( Let g[x] denote the se for "g" on cpu "x". ) Suppose that we have root->a and that a enters a throttled state, immediately followed by a[0]->t1 (the only task running on cpu[0]) blocking: put_prev_task(group_cfs_rq(a[0]), t1) put_prev_entity(..., t1) check_cfs_rq_runtime(group_cfs_rq(a[0])) throttle_cfs_rq(group_cfs_rq(a[0])) Then, before unthrottling occurs, let a[0]->b[0]->t2 wake for the first time: enqueue_task_fair(rq[0], t2) enqueue_entity(group_cfs_rq(b[0]), t2) enqueue_entity_load_avg(group_cfs_rq(b[0]), t2) account_entity_enqueue(group_cfs_ra(b[0]), t2) update_cfs_shares(group_cfs_rq(b[0])) < skipped because b is part of a throttled hierarchy > enqueue_entity(group_cfs_rq(a[0]), b[0]) ... We now have b[0] enqueued, yet group_cfs_rq(a[0])->load.weight == 0 which violates invariants in several code-paths. Eliminate the possibility of this by initializing group entity weight.

commit 927b54fc upstream. __start_cfs_bandwidth calls hrtimer_cancel while holding rq->lock, waiting for the hrtimer to finish. However, if sched_cfs_period_timer runs for another loop iteration, the hrtimer can attempt to take rq->lock, resulting in deadlock. Fix this by ensuring that cfs_b->timer_active is cleared only if the _latest_ call to do_sched_cfs_period_timer is returning as idle. Then __start_cfs_bandwidth can just call hrtimer_try_to_cancel and wait for that to succeed or timer_active == 1. Signed-off-by:

commit 1ee14e6c upstream. When we transition cfs_bandwidth_used to false, any currently throttled groups will incorrectly return false from cfs_rq_throttled. While tg_set_cfs_bandwidth will unthrottle them eventually, currently running code (including at least dequeue_task_fair and distribute_cfs_runtime) will cause errors. Fix this by turning off cfs_bandwidth_used only after unthrottling all cfs_rqs. Tested: toggle bandwidth back and forth on a loaded cgroup. Caused crashes in minutes without the patch, hasn't crashed with it. Signed-off-by:

commit 2690d97a upstream. Commit 5901b6be attempted to introduce IPv6 support into IRC NAT helper. By doing so, the following code seemed to be removed by accident: ip = ntohl(exp->master->tuplehash[IP_CT_DIR_REPLY].tuple.dst.u3.ip); sprintf(buffer, "%u %u", ip, port); pr_debug("nf_nat_irc: inserting '%s' == %pI4, port %u\n", buffer, &ip, port); This leads to the fact that buffer[] was left uninitialized and contained some stack value. When we call nf_nat_mangle_tcp_packet(), we call strlen(buffer) on excatly this uninitialized buffer. If we are unlucky and the skb has enough tailroom, we overwrite resp. leak contents with values that sit on our stack into the packet and send that out to the receiver. Since the rather informal DCC spec [1] does not seem to specify IPv6 support right now, we log such occurences so that admins can act accordingly, and drop the packet. I've looked into XChat source, and IPv6 is not supported there: addresses are in u32 and print via %u format string. Therefore, restore old behaviour as in IPv4, use snprintf(). The IRC helper does not support IPv6 by now. By this, we can safely use strlen(buffer) in nf_nat_mangle_tcp_packet() and prevent a buffer overflow. Also simplify some code as we now have ct variable anyway. [1] http://www.irchelp.org/irchelp/rfc/ctcpspec.html Fixes: 5901b6be ("netfilter: nf_nat: support IPv6 in IRC NAT helper") Signed-off-by:

commit 778037e1 upstream. Commit 6d9252bd (clk: Add support for power of two type dividers) merged in v3.6 added the _get_val function to convert a divisor value to a register field value depending on the flags. However it used the type u8 for the div field, causing divisors larger than 255 to be masked and the resultant clock rate to be too high. E.g. in my case an 11bit divider was supposed to divide 24.576 MHz down to 32.768KHz. The divisor was correctly calculated as 750 (0x2ee). This was masked to 238 (0xee) resulting in a frequency of 103.26KHz. Signed-off-by:

commit f8dae006 upstream. Helge Deller noted a few weeks ago problems with the AIO support on parisc. This change is the result of numerous iterations on how best to deal with this problem. The solution adopted here is to provide full cache coherency in a uniform manner on all parisc systems. This involves calling flush_dcache_page() on kmap operations and flush_kernel_dcache_page() on kunmap operations. As a result, the copy_user_page() and clear_user_page() functions can be removed and the overall code is simpler. The change ensures that both userspace and kernel aliases to a mapped page are invalidated and flushed. This is necessary for the correct operation of PA8800 and PA8900 based systems which do not support inequivalent aliases. With this change, I have observed no cache related issues on c8000 and rp3440. It is now possible for example to do kernel builds with "-j64" on four way systems. On systems using XFS file systems, the patch recently posted by Mikulas Patocka to "fix crash using XFS on loopback" is needed to avoid a hang caused by an uninitialized lock passed to flush_dcache_page() in the page struct.

[ Upstream commit 1cdbcb79 ] This is a generic solution to resolve a specific problem that I have observed. If the encapsulation of an skb changes then ability to offload checksums may also change. In particular it may be necessary to perform checksumming in software. An example of such a case is where a non-GRE packet is received but is to be encapsulated and transmitted as GRE. Another example relates to my proposed support for for packets that are non-MPLS when received but MPLS when transmitted. The cost of this change is that the value of the csum variable may be checked when it previously was not. In the case where the csum variable is true this is pure overhead. In the case where the csum variable is false it leads to software checksumming, which I believe also leads to correct checksums in transmitted packets for the cases described above. Further analysis: This patch relies on the return value of can_checksum_protocol() being correct and in turn the return value of skb_network_protocol(), used to provide the protocol parameter of can_checksum_protocol(), being correct. It also relies on the features passed to skb_segment() and in turn to can_checksum_protocol() being correct. I believe that this problem has not been observed for VLANs because it appears that almost all drivers, the exception being xgbe, set vlan_features such that that the checksum offload support for VLAN packets is greater than or equal to that of non-VLAN packets. I wonder if the code in xgbe may be an oversight and the hardware does support checksumming of VLAN packets. If so it may be worth updating the vlan_features of the driver as this patch will force such checksums to be performed in software rather than hardware. Signed-off-by:

[ Upstream commit fe0d692b ] br_multicast_set_hash_max() is called from process context in net/bridge/br_sysfs_br.c by the sysfs store_hash_max() function. br_multicast_set_hash_max() calls spin_lock(&br->multicast_lock), which can deadlock the CPU if a softirq that also tries to take the same lock interrupts br_multicast_set_hash_max() while the lock is held . This can happen quite easily when any of the bridge multicast timers expire, which try to take the same lock. The fix here is to use spin_lock_bh(), preventing other softirqs from executing on this CPU. Steps to reproduce: 1. Create a bridge with several interfaces (I used 4). 2. Set the "multicast query interval" to a low number, like 2. 3. Enable the bridge as a multicast querier. 4. Repeatedly set the bridge hash_max parameter via sysfs. # brctl addbr br0 # brctl addif br0 eth1 eth2 eth3 eth4 # brctl setmcqi br0 2 # brctl setmcquerier br0 1 # while true ; do echo 4096 > /sys/class/net/br0/bridge/hash_max; done Signed-off-by:
