motivation for this change is that currently, we're not tracking all the

performed over the linked list by qdisc_match_from_root() is rather

This patch brings more consistency between ioctl and rtnl based ppp
devices by generating device names using the PPP unit identifer as

This patch simplifies how we update fsc and calculate vt from it - while
keeping the expected functionality identical with how hfsc behaves
curently. It also fixes a certain issue introduced with
a very old patch.
The idea is, that instead of correcting cl_vt before fsc curve update
(rtsc_min) and correcting cl_vt after calculation (rtsc_y2x) to keep
cl_vt local to the current period - we can simply rely on virtual times
and curve values always being in sync - analogously to how rsc and usc
function, except that we use virtual time here.
Why hasn't it been done since the beginning this way ? The likely scenario
(basing on the code trying to correct curves whenever possible) was to
keep the virtual times as small as possible - as they have tendency to
"gallop" forward whenever their siblings and other fair sharing
subtrees are idling. On top of that, current code is subtly bugged, so
cumulative time (without any corrections) is always kept and used in
init_vf() when a new backlog period begins (using cl_cvtoff).
Is cumulative value safe ? Generally yes, though corner cases are easy
to create. For example consider:
1gbit interface
some 100kbit leaf, everything else idle
With current tick (64ns) 1s is 15625000 ticks, but the leaf is alone and
it's virtual time, so in reality it's 10000 times more. ITOW 38 bits are
needed to hold 1 second. 54 - 1 day, 59 - 1 month, 63 - 1 year (all
logarithms rounded up). It's getting somewhat dangerous, but also
requires setup excusing this kind of values not mentioning permanently
backlogged class for a year. In near most extreme case (10gbit, 10kbit
leaf), we have "enough" to hold ~13.6 days in 64 bits.
Well, the issue remains mostly theoretical and cl_cvtoff has been
working fine for all those years. Sensible configuration are de-facto
immune to this issue, and not so sensible can solve it with a cronjob
and its period inversely proportional to the insanity of such setup =)
Now let's explain the subtle bug mentioned earlier.
The issue is related to how offsets are kept and how we calculate
virtual times and update fair service curve(s). The issue itself is
subtle, but easy to observe with long m1 segments. It was introduced in
rather old patch:
Commit 99296150c7: "[NET_SCHED]: O(1) children vtoff adjustment
in HFSC scheduler"
(available in git://git.kernel.org/pub/scm/linux/kernel/git/tglx/history.git)
Originally when a new backlog period was started, cl_vtoff of each
sibling was updated with cl_cvtmax from past period - naturally moving
all cl_vt to proper starting point. That patch adjusted it so cumulative
offset is kept in the parent, and there is no need for traversing the
list (as any subsequent child activation derives new vt from already
active sibling(s)).
But with this change, cl_vtoff (of each sibling) is no longer persistent
across the inactivity periods, as it's calculated from parent's
cl_cvtoff on a new backlog period, conflicting with the following curve
correction from the previous period:
if (cl->cl_virtual.x == vt) {
cl->cl_virtual.x -= cl->cl_vtoff;
cl->cl_vtoff = 0;
}
This essentially tries to keep curve as if it was local to the period
and resets cl_vtoff (cumulative vt offset of the class) to 0 when
possible (read: when we have an intersection or if a new curve is below
the old one). But then it's recalculated from cl_cvtoff on next active
period. Then rtsc_min() call preceding the above if() doesn't really
do what we expect it to do in such scenario - as it calculates the
minimum of corrected curve (from the previous backlog period) and the
new uncorrected curve (with offset derived from cl_cvtoff).
Example:
tc class add dev $ife parent 1:0 classid 1:1 hfsc ls m2 100mbit ul m2 100mbit
tc class add dev $ife parent 1:1 classid 1:10 hfsc ls m1 80mbit d 10s m2 20mbit
tc class add dev $ife parent 1:1 classid 1:11 hfsc ls m2 20mbit
start B, keep it backlogged, let it run 6s (30s worth of vt as A is idle)
pause B briefly to force cl_cvtoff update in parent (whole 1:1 going idle)
start A, let it run 10s
pause A briefly to force rtsc_min()
At this point we would expect A to continue at 20mbit after a brief
moment of 80mbit. But instead A will use 80mbit for full 10s again. It's
the effect of first correcting A (during 'start A'), and then - after
unpausing - calculating rtsc_min() from old corrected and new uncorrected
curve.
The patch fixes this bug and keepis vt and fsc in sync (virtual times
are cumulative, not local to the backlog period).

So we should not send source-list change if there is a filter-mode change.
Here are two scenarios:
1. Group deleted and filter mode is EXCLUDE, which means we need send a
TO_IN { }.
2. Not group deleted, but has pcm->crcount, which means we need send a

At the same time, if the type is ALLOW or BLOCK, and have psf->sf_crcount,
we stop add records and decrease sf_crcount directly

The dhcp code only waits 1s between sending DHCP requests on different
devices and only accepts an answer for the device that sent out the last
request. Only the timeout at the end of a loop is increased iteratively
which favours only the last device. This makes it impossible to work
with a dhcp server that takes little more than 1s connected to a device
that is not the last one.
Instead of also increasing the inter-device timeout, teach the code to
handle delayed replies.
To accomplish that, make *ic_dev track the current ic_device instead of
the current net_device and adapt all users accordingly. The relevant
change then is to reset d to ic_dev on a reply to assert that the
followup request goes through the right device.

be2net: patch set
Patch 1 fixes the driver to workaournd a bug in the Lancer FW in the
vlan-config cmd processing. The FW in some cases clears the vlan-promisc
setting even if it cannot apply the vlan filter. The driver has no means
of knowing if the vlan-promisc setting has been cleared or not. This
patch now explicitly clears the vlan-promisc setting via the RX-Filter cmd
and then tries to program the vlan-list.
Patch 2 fixes the failure path in the vlan vid add code.
The driver currently removes a new vid from the adapter->vids[] array if
be_vid_config() returns an error, which occurs when there is an error in
HW/FW. This is wrong. After the HW/FW error is recovered from, we need the
complete vids[] array to re-program the vlan list.
Patch 3 fixes the ndo_set_rx_mode() path to avoid unnecessary multicast
list updates to the FW. Each time the ndo_set_rx_mode() routine is called,
the driver programs the multicast list in the adapter without checking
if there are any changes to the list. This leads to a flood of RX_FILTER
cmds when a number of vlan interfaces are configured over the device,
as the ndo_ gets called for each vlan interface. To avoid this, we now
use __dev_mc_sync() and __dev_uc_sync() API, but only to detect if there
is a change in the mc/uc lists. Now that we use this API, the code has to
be-designed to issue these API calls for each invocation of the ndo_ call.
Patch 4 replaces polling with sleeping in the FW completion path.
The ndo_set_rx_mode() and ndo_add/del_vxlan_port() calls may be called with
BHs disabled. The driver currently issues the required cmds to the FW in
these contexts and polls on completions from the FW, while BHs remain
disabled. This can cause either packet loss or packet reception to be
delayed on that CPU. This patch defers processing of the above cmds to a
separate workqueue. With this change, FW cmds are now issued only in process
context. Now that the FW cmds are issued only in process context, they can
sleep waiting for a completion instead of polling.

Commit 52253db924 ("sctp: also point GSO head_skb to the sk when
it's available") used event->chunk->head_skb to get the head_skb in
sctp_ulpevent_set_owner().
But at that moment, the event->chunk was NULL, as it cloned the skb
in sctp_ulpevent_make_rcvmsg(). Therefore, that patch didn't really
work.
This patch is to move the event->chunk initialization before calling
sctp_ulpevent_receive_data() so that it uses event->chunk when it's
valid.

vxlan driver has bypass for local vxlan traffic, but that
depends on information about all VNIs on local system in
vxlan driver. This is not available in case of LWT.
Therefore following patch disable encap bypass for LWT
vxlan traffic.
