Patrick Farrell [Mon, 14 Aug 2017 10:09:35 +0000 (05:09 -0500)]
LU-8276 ldlm: Make lru clear always discard read lock pages

A significant amount of time is sometimes spent during
lru clearing (IE, echo 'clear' > lru_size) checking
pages to see if they are covered by another read lock.
Since all unused read locks will be destroyed by this
operation, the pages will be freed momentarily anyway,
and this is a waste of time.

This patch sets the LDLM_FL_DISCARD_DATA flag on all the PR
locks which are slated for cancellation by
ldlm_prepare_lru_list when it is called from
ldlm_ns_drop_cache.

The case where another lock covers those pages (and is in
use and so does not get cancelled by lru clear) is safe for
a few reasons:

1. When discarding pages, we wait (discard_cb->cl_page_own)
until they are in the cached state before invalidating.
So if they are actively in use, we'll wait until that use
is done.

2. Removal of pages under a read lock is something that can
happen due to memory pressure, since these are VFS cache
pages. If a client reads something which is then removed
from the cache and goes to read it again, this will simply
generate a new read request.

This has a performance cost for that reader, but if anyone
is clearing the ldlm lru while actively doing I/O in that
namespace, then they cannot expect good performance.

In the case of many read locks on a single resource, this
improves cleanup time dramatically.  In internal testing at
Cray with ~80,000 read locks on a single file, this improves
cleanup time from ~60 seconds to ~0.5 seconds.  This also
slightly improves cleanup speed in the case of 1 or a few
read locks on a file.

LU-9767 utils: validate filesystem name for mkfs.lustre

The patch "LU-6401 uapi: turn lustre_param.h into a proper
UAPI header" removed various user land functions used to
validate poolnames and file system names were removed. The
checks instead were enforced on the kernel side to ensure
any possible user land software directly interfacing to the
kernel wouldn't be able to break things badly. For the case
of formating the backend file system no kernel interaction
doesn't happen until it tries to mount the MDT/OST/MGT which
is very late in the process. So for this case lets add back
the file system name verification to mkfs.lustre to warn
users long before they try to mount anything.

Secondly we remove the verify_poolname() in lfs.c since
it duplicates extract_fsname_poolname() in obd.c. Their
is no need to do the same test twice. The function
pool_cmd() calls the ioctl for pool handling which in
turn returns an error code. Use this error code to notify
the user what mistake they did for their pool command.
For the MGS kernel code mgs_extract_fs_pool() was checking
MTI_NAME_MAXLEN instead of LUSTRE_MAXFSNAME. Also use
LUSTRE_MAXFSNAME instead of the raw number in the function
server_name2fsname() located in obd_mount.c.

LU-9480 lnet: implement Peer Discovery

Implement Peer Discovery.

A peer is queued for discovery by lnet_peer_queue_for_discovery().
This set LNET_PEER_DISCOVERING, to indicate that discovery is in
progress.

The discovery thread lnet_peer_discovery() checks the peer and
updates its state as appropriate.

If LNET_PEER_DATA_PRESENT is set, then a valid Push message or
Ping reply has been received. The peer is updated in accordance
with the data, and LNET_PEER_NIDS_UPTODATE is set.

If LNET_PEER_PING_FAILED is set, then an attempt to send a Ping
message failed, and peer state is updated accordingly. The discovery
thread can do some cleanup like unlinking an MD that cannot be done
from the message event handler.

If LNET_PEER_PUSH_FAILED is set, then an attempt to send a Push
message failed, and peer state is updated accordingly. The discovery
thread can do some cleanup like unlinking an MD that cannot be done
from the message event handler.

If LNET_PEER_PING_REQUIRED is set, we must Ping the peer in order to
correctly update our knowledge of it. This is set, for example, if
we receive a Push message for a peer, but cannot handle it because
the Push target was too small. In such a case we know that the
state of the peer is incorrect, but need to do extra work to obtain
the required information.

If discovery is not enabled, then the discovery process stops here
and the peer is marked with LNET_PEER_UNDISCOVERED. This tells the
discovery process that it doesn't need to revisit the peer while
discovery remains disabled.

If LNET_PEER_NIDS_UPTODATE is not set, then we have reason to think
the lnet_peer is not up to date, and will Ping it.

The peer needs a Push if it is multi-rail and the ping buffer
sequence number for this node is newer than the sequence number it
has acknowledged receiving by sending an Ack of a Push.

If none of the above is true, then discovery has completed its work
on the peer.

Discovery signals that it is done with a peer by clearing the
LNET_PEER_DISCOVERING flag, and setting LNET_PEER_DISCOVERED or
LNET_PEER_UNDISCOVERED as appropriate. It then dequeues the peer
and clears the LNET_PEER_QUEUED flag.

When the local node is discovered via the loopback network, the
peer structure that is created will have an lnet_peer_ni for the
local loopback interface. Subsequent traffic from this node to
itself will use the loopback net.

LU-9480 lnet: preferred NIs for non-Multi-Rail peers

When a node sends a message to a peer NI, there may be
a preferred local NI that should be the source of the
message. This is in particular the case for non-Multi-
Rail (NMR) peers, as an NMR peer depends in some cases
on the source address of a message to correctly identify
its origin. (This as opposed to using a UUID provided by
a higher protocol layer.)

Implement this by keeping an array of preferred local
NIDs in the lnet_peer_ni structure. The case where only
a single NID needs to be stored is optimized so that this
can be done without needing to allocate any memory.

A flag in the lnet_peer_ni, LNET_PEER_NI_NON_MR_PREF,
indicates that the preferred NI was automatically added
for an NMR peer. Note that a peer which has not been
explicitly configured as Multi-Rail will be treated as
non-Multi-Rail until proven otherwise. These automatic
preferences will be cleared if the peer is changed to
Multi-Rail.

- lnet_peer_ni_set_non_mr_pref_nid()
  set NMR preferred NI for peer_ni
- lnet_peer_ni_clr_non_mr_pref_nid()
  clear NMR preferred NI for peer_ni

LU-6210 utils: Use C99 struct initializers in lsnapshot

This patch makes no functional changes.  The long_options struct
initializers in lsnapshot are updated to C99 syntax.  The long
options are renamed to long_opts for consistency.

C89 positional initializers require values to be placed in the
correct order. This will cause errors if the fields of the struct
definition are reordered or fields are added or removed. C99 named
initializers avoid this problem, and also automatically clear any
values that are not explicitly set.

step 1: create an empty file
step 2: buffer write data to file, at this time project id 0 is packed.
step 3: chattr file's project id

chattr is issued in this time window and chattr on OST is done before
write PRC being processed on OST:

That means we have changed file's project ID, but ofd_attr_handle_id()
did not clear S_ISUID and S_ISGID for this case. Write RPC arrived on
OST, first write RPC will call ofd_attr_handle_id() to set attribute.
Unfortunately it will think this is first write as S_ISUID and S_ISGID
is set, project id will be reset with packed id 0, thus we got wrong
project accounting.

We should use another file mode to indicate whether
project id has been initialized, this patch tries to
fix this problem.

Linux-commit: 0871d551af37c72c308397c16c31bae945e6a79d

so just add debug buffer size check and resizing and the same

Properly handle debugfs read- and write-only files

It turns out that unlike procfs, debugfs does not really enforce
permissions for root (similar to regular filesystems), so we need
to ensure we are not providing ->write() method to read-only files
and ->read() method for write-only files at registration.

This fixes a couple of crashes on unexpected access.

LU-7356 build: handle configure options for mount plugin

Currently if you build lustre with configure options
--disable-shared and/or --disable-static it will fail
to build in the case of the mount plugins. The mount
plugins are always built to be sharable code using
libtool but this is not compatiable with the confiure
--disable-share option. The solution was to create a
temporary static library and for the static case we
directly link into the lustre utilites. If shared
libraries are enabled then that temporary library
is turned into a dynamic plugin. The lustre utilites
was updated to handle both cases.
