rbd_dev->disk tear down vs rbd_watch_cb() race shouldn't be a problem anymore thanks to EXISTS and REMOVING checks in rbd_dev_update_size(). A similar race could occur on "rbd map", see commit 811c6688 ("rbd: fix rbd map vs notify races"). Signed-off-by:

Currently, we don't have a real feedback mechanism in place for when we start seeing buffered writeback errors. If writeback is failing, there is nothing that prevents an application from continuing to dirty pages that aren't being cleaned. In the event that we're seeing write errors of any sort occur on an inode, have the callback set a flag to force further writes to be synchronous. When the next write succeeds, clear the flag to allow buffered writeback to continue. Since this is just a hint to the write submission mechanism, we only take the i_ceph_lock when a lockless check shows that the flag needs to be changed. Signed-off-by:

This reverts commit b109eec6. If I'm filling up a filesystem with this sort of command: $ dd if=/dev/urandom of=/mnt/cephfs/fillfile bs=2M oflag=sync ...then I'll eventually get back EIO on a write. Further calls will give us ENOSPC. I'm not sure what prompted this change, but I don't think it's what we want to do. If writepages failed, we will have already set the mapping error appropriately, and that's what gets reported by fsync() or close(). __filemap_fdatawait_range however, does this: wait_on_page_writeback(page); if (TestClearPageError(page)) ret = -EIO; ...and that -EIO ends up trumping the mapping's error if one exists. When writepages fails, we only want to set the error in the mapping, and not flag the individual pages. Signed-off-by:

Have the client store and update the osdc epoch_barrier when a cap message comes in with one. When sending cap messages, send the epoch barrier as well. This allows clients to inform servers that their released caps may not be used until a particular OSD map epoch. Signed-off-by:

Jeff Layton authored
Cephfs can get cap update requests that contain a new epoch barrier in them. When that happens we want to pause all OSD traffic until the right map epoch arrives. Add an epoch_barrier field to ceph_osd_client that is protected by the osdc->lock rwsem. When the barrier is set, and the current OSD map epoch is below that, pause the request target when submitting the request or when revisiting it. Add a way for upper layers (cephfs) to update the epoch_barrier as well. If we get a new map, compare the new epoch against the barrier before kicking requests and request another map if the map epoch is still lower than the one we want. If we get a map with a full pool, or at quota condition, then set the barrier to the current epoch value. Signed-off-by:

When a Ceph volume hits capacity, a flag is set in the OSD map to indicate that, and a new map is sprayed around the cluster. With cephfs we want it to shut down any abortable requests that are in progress with an -ENOSPC error as they'd just hang otherwise. Add a new ceph_osdc_abort_on_full helper function to handle this. It will first check whether there is an out-of-space condition in the cluster and then walk the tree and abort any request that has r_abort_on_full set with a -ENOSPC error. Call this new function directly whenever we get a new OSD map. Signed-off-by:

Jeff Layton authored
Usually, when the osd map is flagged as full or the pool is at quota, write requests just hang. This is not what we want for cephfs, where it would be better to simply report -ENOSPC back to userland instead of stalling. If the caller knows that it will want an immediate error return instead of blocking on a full or at-quota error condition then allow it to set a flag to request that behavior. Set that flag in ceph_osdc_new_request (since ceph.ko is the only caller), and on any other write request from ceph.ko. A later patch will deal with requests that were submitted before the new map showing the full condition came in. Signed-off-by:

Current cephfs client uses string to indicate start position of readdir. The string is last entry of previous readdir reply. This approach does not work for seeky readdir because we can not easily convert the new postion to a string. For seeky readdir, mds needs to return dentries from the beginning. Client keeps retrying if the reply does not contain the dentry it wants. In current version of ceph, mds sorts CDentry in its cache in hash order. Client also uses dentry hash to compose dir postion. For seeky readdir, if client passes the hash part of dir postion to mds. mds can avoid replying useless dentries. Signed-off-by:

Newer hardware has uncovered a bug in the software implementation of using MWAITX for the delay function. A value of 0 for the timer is meant to indicate that a timeout will not be used to exit MWAITX. On newer hardware this can result in MWAITX never returning, resulting in NMI soft lockup messages being printed. On older hardware, some of the other conditions under which MWAITX can exit masked this issue. The AMD APM does not currently document this and will be updated. Please refer to http://marc.info/?l=kvm&m=148950623231140 for information regarding NMI soft lockup messages on an AMD Ryzen 1800X. This has been root-caused as a 0 passed to MWAITX causing it to wait indefinitely. This change has the added benefit of avoiding the unnecessary setup of MONITORX/MWAITX when the delay value is zero.

If the netdev is accessed before the urbs are initialized, there will be NULL pointer dereferences. That is avoided by registering it when it is fully initialized.

Andrey found a way to trigger the WARN_ON_ONCE(delta < len) in skb_try_coalesce() using syzkaller and a filter attached to a TCP socket. As we did recently in commit 158f323b ("net: adjust skb->truesize in pskb_expand_head()") we can adjust skb->truesize from ___pskb_trim(), via a call to skb_condense(). If all frags were freed, then skb->truesize can be recomputed. This call can be done if skb is not yet owned, or destructor is sock_edemux(). Signed-off-by:

Andrey found a way to trigger the WARN_ON_ONCE(delta < len) in skb_try_coalesce() using syzkaller and a filter attached to a TCP socket over loopback interface. I believe one issue with looped skbs is that tcp_trim_head() can end up producing skb with under estimated truesize. It hardly matters for normal conditions, since packets sent over loopback are never truncated. Bytes trimmed from skb->head should not change skb truesize, since skb->head is not reallocated.

On slave list updates, the bonding driver computes its hard_header_len as the maximum of all enslaved devices's hard_header_len. If the slave list is empty, e.g. on last enslaved device removal, ETH_HLEN is used. Since the bonding header_ops are set only when the first enslaved device is attached, the above can lead to header_ops->create() being called with the wrong skb headroom in place. If bond0 is configured on top of ipoib devices, with the following commands: ifup bond0 for slave in $BOND_SLAVES_LIST; do ip link set dev $slave nomaster done ping -c 1 <ip on bond0 subnet> we will obtain a skb_under_panic() with a similar call trace: skb_push+0x3d/0x40 push_pseudo_header+0x17/0x30 [ib_ipoib] ipoib_hard_header+0x4e/0x80 [ib_ipoib] arp_create+0x12f/0x220 arp_send_dst.part.19+0x28/0x50 arp_solicit+0x115/0x290 neigh_probe+0x4d/0x70 __neigh_event_send+0xa7/0x230 neigh_resolve_output+0x12e/0x1c0 ip_finish_output2+0x14b/0x390 ip_finish_output+0x136/0x1e0 ip_output+0x76/0xe0 ip_local_out+0x35/0x40 ip_send_skb+0x19/0x40 ip_push_pending_frames+0x33/0x40 raw_sendmsg+0x7d3/0xb50 inet_sendmsg+0x31/0xb0 sock_sendmsg+0x38/0x50 SYSC_sendto+0x102/0x190 SyS_sendto+0xe/0x10 do_syscall_64+0x67/0x180 entry_SYSCALL64_slow_path+0x25/0x25 This change addresses the issue avoiding updating the bonding device hard_header_len when the slaves list become empty, forbidding to shrink it below the value used by header_ops->create().

Upper layer GRO handlers can not handle IP fragments, so exit GRO processing in this case. This fixes ESP GRO because the packet must be reassembled before we can decapsulate, otherwise we get authentication failures. It also aligns IPv4 to IPv6 where packets with fragmentation headers are not passed to upper layer GRO handlers. Fixes: 7785bba2 ("esp: Add a software GRO codepath") Signed-off-by:

Tony Lindgren reports a kernel oops that resulted from my compile-time fix on the default config. This shows two problems: a) configurations that did not already enable PTP_1588_CLOCK will now miss the cpts driver b) when cpts support is disabled, the driver crashes. This is a preexisting problem that we did not notice before my patch. While the second problem is still being investigated, this modifies the dependencies again, getting us back to the original state, with another 'select NET_PTP_CLASSIFY' added in to avoid the original link error we got, and the 'depends on POSIX_TIMERS' to hide the CPTS support when turning it on would be useless. Cc: stable@vger.kernel.org # 4.11 needs this Fixes: 07fef362 ("cpsw/netcp: cpts depends on posix_timers") Signed-off-by:

When the base driver is enabled but all SoC specific drivers are turned off, we now get a build error after code was added to always refer to the clk gates: drivers/clk/built-in.o: In function `ccu_pll_notifier_cb': :(.text+0x154f8): undefined reference to `ccu_gate_helper_disable' :(.text+0x15504): undefined reference to `ccu_gate_helper_enable' This changes the Kconfig to always require the gate code to be built-in when CONFIG_SUNXI_CCU is set.
