staging: lustre: avoid intensive reconnecting for ko2iblnd
When there is a connection race between two nodes and one side
of the connection is rejected by the other side. o2iblnd will
reconnect immediately, this is going to generate a lot of
trashes if:
- race winner is slow and can't send out connecting request
in short time.
- remote side leaves a cmid in TIMEWAIT state, which will reject
future connection requests
To resolve this problem, this patch changed the reconnection
behave: reconnection is submitted by connd only if a zombie
connection is being destroyed and there is a pending
reconnection request for the corresponding peer.
Also, after a few rejections, reconnection will have a time
interval between each attempt.

staging: lustre: Change connect peer failed cleanup order
A race condition has been found where connd is cleaning up failed
connections, the peer ref counter goes to zero, but we stil have
a connecting counter > 0.
One possible race is when we are retrying a connection by
calling kiblnd_connect_peer() which itself fails and decrements
the peer ref counter and gets swapped out before it can decrement
the connecting counter. connd swaps in and cleans up the
connection where it sees a peer ref counter of 1 and a connecting
counter of 1. This will trigger the assert seen in LU-7210 when
it decrements the peer counter.
The solution: be sure to decrement the connecting counter
before decrementing the peer counter in the peer connect

staging: lustre: replace direct LNet HZ access with kernel APIs
On some customers' systems, the kernel was compiled with HZ defined
to 100, instead of 1000. This improves performance for HPC applications.
However, to use these systems with Lustre, customers have to re-build
Lustre for the kernel because Lustre directly uses the defined constant
HZ.
Since kernel 2.6.21, some non-HZ dependent timing APIs become non-
inline functions, which can be used in Lustre codes to replace the
direct HZ access.
These kernel APIs include:
jiffies_to_msecs()
jiffies_to_usecs()
jiffies_to_timespec()
msecs_to_jiffies()
usecs_to_jiffies()
timespec_to_jiffies()
And here are some samples of the replacement:
HZ -> msecs_to_jiffies(MSEC_PER_SEC)
n * HZ -> msecs_to_jiffies(n * MSEC_PER_SEC)
HZ / n -> msecs_to_jiffies(MSEC_PER_SEC / n)
n / HZ -> jiffies_to_msecs(n) / MSEC_PER_SEC
n / HZ * 1000 -> jiffies_to_msecs(n)

staging: lustre: Use after free in lnet_ptl_match_delay()
In lnet_ptl_match_delay() we check msg->msg_rx_delayed to see whether
the message has been added to the delay queue. But this check is done
after lnet_ptl_unlock() and lnet_res_unlock(), and the message can be
processed and freed before the check.
Replace the check with checking rc against LNET_MATCHMD_NONE, which
is how the callers of lnet_ptl_match_delay() know whether the message
was added to the delay queue. To make this work we reset rc in the
loop when there was no match and the message hasn't been delayed. In
addition reorganize the code and add comments to clarify the logic.
In lnet_ptl_match_md() a similar msg->msg_rx_delayed is replaced for
the same reason.

staging: lustre: Ignore hops if not explicitly set
Since the # of hops is not a mandatory parameter the LU-6060
patch will cause problems to already existing systems since it
changes the behavior by which a route is determined down.
To fix this case the # of hops now defaults to LNET_UNDEFINED_HOPS
if no hop count is specified.
LNET_UNDEFINED_HOPS is defined to ((__u32)-1). When it's printed as
%d, it displays as -1.
__u32 is used through out the call stack for hop count to explicitly
define the size of the hop count and to avoid any sizing issues when
passing data to and from the kernel.
To keep existing behavior both lnet_compare_routes() and LNetDist()
will treat undefined hop count as hop count 1.
When executing the logic in lnet_parse_rc_info() there is no
longer an assumption that the default hop count is 1. If
the hop count is 1 then it must've been explicitly set by
the user.

staging: lustre: recv could access freed message
When lnet_parse_put calls lnet_ptl_match_md, this function can attach
current message on the delayed list if there is no match. It means
this message can be taken over and freed by another thread who is
posting new MD, then it is not safe for caller of lnet_parse_put to
check this message again.
This patch fixes this issue by adding a local variable "ready_delay"
to store corresponding status of lnet_msg, so lnet doesn't need to
check the message again if lnet_ptl_match_md returned MATCH_NONE for
