2019-07-08iversion: add a routine to update a raw value with a larger oneJeff Layton1-0/+24
Under ceph, clients can be independently updating iversion themselves, while working under comprehensive sets of caps on an inode. In that situation we always want to prefer the largest value of a change attribute. Add a new function that will update a raw value with a larger one, but otherwise leave it alone.

2019-07-07timer: Document TIMER_PINNEDPeter Xu1-8/+19
The flag hints the user that the pinned timers will always be run on a static CPU (because that should be what "pinned" means...) but that's not the truth, at least with the current implementation. For example, currently if a pinned timer is set up but later mod_timer() upon the pinned timer is invoked, mod_timer() will still try to queue the timer on the current processor and migrate the timer if necessary. Document it a bit with the definition of TIMER_PINNED so that all future users will use it correctly.

2019-07-07net/mlx5: Introduce VHCA tunnel device capabilityMax Gurtovoy1-2/+4
When using the device emulation feature (introduced in Bluefield-1 SOC), a privileged function (the device emulation manager) will be able to create a channel to execute commands on behalf of the emulated function. This channel will be a general object of type VHCA_TUNNEL that will have a unique ID for each emulated function. This ID will be passed in each cmd that will be issued by the emulation SW in a well known offset in the command header. This channel is needed since the emulated function doesn't have a normal command interface to the HCA HW, but some basic configuration for that function is needed (e.g. initialize and enable the HCA). For that matter, a specific command-set was defined and only those commands will be issued by the HCA.

We often see various error conditions with NFS4.x that show up with a very high operation count all completing with tk_status < 0 in a short period of time. Add a count to rpc_iostats to record on a per-op basis the ops that complete in this manner, which will enable lower overhead diagnostics.

2019-07-06NFS: send state management on a single connection.NeilBrown1-0/+1
With NFSv4.1, different network connections need to be explicitly bound to a session. During session startup, this is not possible so only a single connection must be used for session startup. So add a task flag to disable the default round-robin choice of connections (when nconnect > 1) and force the use of a single connection. Then use that flag on all requests for session management - for consistence, include NFSv4.0 management (SETCLIENTID) and session destruction Reported-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: NeilBrown <neilb@suse.com> Signed-off-by: Trond Myklebust <trond.myklebust@hammerspace.com>

If the client detects that close-to-open cache consistency has been violated, and that the file or directory has been changed on the server, then do a cache invalidation when we're done working with the file. The reason we don't do an immediate cache invalidation is that we want to avoid performance problems due to false positives. Also, note that we cannot guarantee cache consistency in this situation even if we do invalidate the cache. Signed-off-by: Trond Myklebust <trond.myklebust@hammerspace.com>

2019-07-05mnt_init(): call shmem_init() unconditionallyAl Viro1-1/+1
No point having two call sites (earlier in init_rootfs() from mnt_init() in case we are going to use shmem-style rootfs, later from do_basic_setup() unconditionally), along with the logics in shmem_init() itself to make the second call a no-op... Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2019-07-05don't bother with registering rootfsAl Viro1-0/+3
init_mount_tree() can get to rootfs_fs_type directly and that simplifies a lot of things. We don't need to register it, we don't need to look it up *and* we don't need to bother with preventing subsequent userland mounts. That's the way we should've done that from the very beginning. There is a user-visible change, namely the disappearance of "rootfs" from /proc/filesystems. Note that it's been unmountable all along and it didn't show up in /proc/mounts; however, it *is* a user-visible change and theoretically some script might've been using its presence in /proc/filesystems to tell 2.4.11+ from earlier kernels. *IF* any complaints about behaviour change do show up, we could fake it in /proc/filesystems. I very much doubt we'll have to, though. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2019-07-05init_rootfs(): don't bother with init_ramfs_fs()Al Viro1-1/+0
the only thing done by the latter is making ramfs visible to mount(2); we don't need it there - rootfs is separate and, in fact, made visible to mount(2) in the same init_rootfs(). Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2019-07-04Merge branch 'mlx5-next' of ↵Saeed Mahameed8-34/+344
git://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux Misc updates from mlx5-next branch: 1) Add the required HW definitions and structures for upcoming TLS support. 2) Add support for MCQI and MCQS hardware registers for fw version query. 3) Added hardware bits and structures definitions for sub-functions 4) Small code cleanup and improvement for PF pci driver. 5) Bluefield (ECPF) updates and refactoring for better E-Switch management on ECPF embedded CPU NIC: 5.1) Consolidate querying eswitch number of VFs 5.2) Register event handler at the correct E-Switch init stage 5.3) Setup PF's inline mode and vlan pop when the ECPF is the E-Swtich manager ( the host PF is basically a VF ). 5.4) Handle Vport UC address changes in switchdev mode. 6) Cleanup the rep and netdev reference when unloading IB rep.

Daniel Borkmann says: ==================== pull-request: bpf-next 2019-07-03 The following pull-request contains BPF updates for your *net-next* tree. There is a minor merge conflict in mlx5 due to 8960b38932be ("linux/dim: Rename externally used net_dim members") which has been pulled into your tree in the meantime, but resolution seems not that bad ... getting current bpf-next out now before there's coming more on mlx5. ;) I'm Cc'ing Saeed just so he's aware of the resolution below: ** First conflict in drivers/net/ethernet/mellanox/mlx5/core/en_main.c: <<<<<<< HEAD static int mlx5e_open_cq(struct mlx5e_channel *c, struct dim_cq_moder moder, struct mlx5e_cq_param *param, struct mlx5e_cq *cq) ======= int mlx5e_open_cq(struct mlx5e_channel *c, struct net_dim_cq_moder moder, struct mlx5e_cq_param *param, struct mlx5e_cq *cq) >>>>>>> e5a3e259ef239f443951d401db10db7d426c9497 Resolution is to take the second chunk and rename net_dim_cq_moder into dim_cq_moder. Also the signature for mlx5e_open_cq() in ... drivers/net/ethernet/mellanox/mlx5/core/en.h +977 ... and in mlx5e_open_xsk() ... drivers/net/ethernet/mellanox/mlx5/core/en/xsk/setup.c +64 ... needs the same rename from net_dim_cq_moder into dim_cq_moder. ** Second conflict in drivers/net/ethernet/mellanox/mlx5/core/en_main.c: <<<<<<< HEAD int cpu = cpumask_first(mlx5_comp_irq_get_affinity_mask(priv->mdev, ix)); struct dim_cq_moder icocq_moder = {0, 0}; struct net_device *netdev = priv->netdev; struct mlx5e_channel *c; unsigned int irq; ======= struct net_dim_cq_moder icocq_moder = {0, 0}; >>>>>>> e5a3e259ef239f443951d401db10db7d426c9497 Take the second chunk and rename net_dim_cq_moder into dim_cq_moder as well. Let me know if you run into any issues. Anyway, the main changes are: 1) Long-awaited AF_XDP support for mlx5e driver, from Maxim. 2) Addition of two new per-cgroup BPF hooks for getsockopt and setsockopt along with a new sockopt program type which allows more fine-grained pass/reject settings for containers. Also add a sock_ops callback that can be selectively enabled on a per-socket basis and is executed for every RTT to help tracking TCP statistics, both features from Stanislav. 3) Follow-up fix from loops in precision tracking which was not propagating precision marks and as a result verifier assumed that some branches were not taken and therefore wrongly removed as dead code, from Alexei. 4) Fix BPF cgroup release synchronization race which could lead to a double-free if a leaf's cgroup_bpf object is released and a new BPF program is attached to the one of ancestor cgroups in parallel, from Roman. 5) Support for bulking XDP_TX on veth devices which improves performance in some cases by around 9%, from Toshiaki. 6) Allow for lookups into BPF devmap and improve feedback when calling into bpf_redirect_map() as lookup is now performed right away in the helper itself, from Toke. 7) Add support for fq's Earliest Departure Time to the Host Bandwidth Manager (HBM) sample BPF program, from Lawrence. 8) Various cleanups and minor fixes all over the place from many others. ==================== Signed-off-by: David S.
