pull-request: bpf-next 2021-02-16
The following pull-request contains BPF updates for your *net-next* tree.
There's a small merge conflict between 7eeba1706eba ("tcp: Add receive timestamp
support for receive zerocopy.") from net-next tree and 9cacf81f8161 ("bpf: Remove
extra lock_sock for TCP_ZEROCOPY_RECEIVE") from bpf-next tree. Resolve as follows:
[...]
lock_sock(sk);
err = tcp_zerocopy_receive(sk, &zc, &tss);
err = BPF_CGROUP_RUN_PROG_GETSOCKOPT_KERN(sk, level, optname,
&zc, &len, err);
release_sock(sk);
[...]

We configure the minimum and maximum number of various types of IPA
resources in ipa_resource_config(). It iterates over resource types
in the configuration data and assigns resource limits to each
resource group for each type.
Unfortunately, we are repeatedly initializing the resource data for
the first type, rather than initializing each of the types whose
limits are specified.
Fix this bug.

Some internal PHY's have their events like link change reported by the
MAC interrupt. We have PHY_IGNORE_INTERRUPT to deal with this scenario.
I'm not too happy with this name. We don't ignore interrupts, typically
there is no interrupt exposed at a PHY level. So let's rename it to
PHY_MAC_INTERRUPT. This is in line with phy_mac_interrupt(), which is
called from the MAC interrupt handler to handle PHY events.

The work queue is used to queue reset requests like CHANGE-PARAM or
FAILOVER resets for the worker thread. When the adapter is being removed
the adapter state is set to VNIC_REMOVING and the work queue is flushed
so no new work is added. However the check for adapter being removed is
racy in that the adapter can go into REMOVING state just after we check
and we might end up adding work just as it is being flushed (or after).
The ->rwi_lock is already being used to serialize queue/dequeue work.
Extend its usage ensure there is no race when scheduling/flushing work.

We have a number of unused flags defined today and since we are scarce
on space and may need to introduce new flags in the future remove and
shift every existing flag down into a contiguous assignment.
PHY_BCM_FLAGS_MODE_1000BX was only used internally for the BCM54616S
PHY, so we allocate a driver private structure instead to store that
flag instead of canibalizing one from phydev->dev_flags for that
purpose.

similarly as FAILVOER and MOBILITY events. If we unmap it
in the linux side, we will see errors like

Hardware comes up with default max frame size set to 1518. When using it
with switch it results in actual Ethernet MTU 1492:
1518 - 14 (Ethernet header) - 4 (Broadcom's tag) - 4 (802.1q) - 4 (FCS)
Above means hardware in its default state can't handle standard Ethernet
traffic (MTU 1500).
Define maximum possible Ethernet overhead and always set MAC max frame
length accordingly. This change fixes handling Ethernet frames of length
1506 - 1514.

default
The sja1105 driver has a limitation, extensively described under
Documentation/networking/dsa/sja1105.rst and
Documentation/networking/devlink/sja1105.rst, which says that when the
ports are under a bridge with vlan_filtering=1, traffic to and from
the network stack is not possible, unless the driver-specific
best_effort_vlan_filtering devlink parameter is enabled.
For users, this creates a 'wtf' moment. They need to go to the
documentation and find about the existence of this property, then maybe
install devlink and set it to true.
Having best_effort_vlan_filtering enabled by the kernel by default
delays that 'wtf' moment (maybe up to the point that it never even
happens). The user doesn't need to care that the driver supports
addressing the ports individually by retagging VLAN IDs until he/she
needs to use more than 32 VLAN IDs (since there can be at most 32
retagging rules). Only then do they need to think whether they need the
full VLAN table, at the expense of no individual port addressing, or
not.
But the odds that an sja1105 user will need more than 32 VLANs
terminated by the CPU is probably low. And, if we were to follow the
principle that more advanced use cases should require more advanced
preparation steps, then it makes more sense for ping to 'just work'
while CPU termination of > 32 VLAN IDs to require a bit more forethought
and possibly a driver-specific devlink param.
So we should be able to safely change the default here, and make this
driver act just a little bit more sanely out of the box.

Smatch is confused by the fact that a 32-bit BIT(port) macro is passed
as argument to the ocelot_ifh_set_dest function and warns:
ocelot_xmit() warn: should '(((1))) << (dp->index)' be a 64 bit type?
seville_xmit() warn: should '(((1))) << (dp->index)' be a 64 bit type?
The destination port mask is copied into a 12-bit field of the packet,
starting at bit offset 67 and ending at 56.
So this DSA tagging protocol supports at most 12 bits, which is clearly
less than 32. Attempting to send to a port number > 12 will cause the
packing() call to truncate way before there will be 32-bit truncation
due to type promotion of the BIT(port) argument towards u64.
Therefore, smatch's fears that BIT(port) will do the wrong thing and
cause unexpected truncation for "port" values >= 32 are unfounded.
Nonetheless, let's silence the warning by explicitly passing an u64
value to ocelot_ifh_set_dest, such that the compiler does not need to do
a questionable type promotion.

The function uses a goto-based loop, which may lead to an earlier error
getting discarded by a later iteration. Exit this ad-hoc loop when an
error was encountered.
The out-of-memory error path additionally fails to fill a structure
field looked at by xen_blkbk_unmap_prepare() before inspecting the
handle which does get properly set (to BLKBACK_INVALID_HANDLE).
Since the earlier exiting from the ad-hoc loop requires the same field
filling (invalidation) as that on the out-of-memory path, fold both
paths. While doing so, drop the pr_alert(), as extra log messages aren't
going to help the situation (the kernel will log oom conditions already
anyway).
This is XSA-365.

In particular -ENOMEM may come back here, from set_foreign_p2m_mapping().
Don't make problems worse, the more that handling elsewhere (together
with map's status fields now indicating whether a mapping wasn't even
attempted, and hence has to be considered failed) doesn't require this
odd way of dealing with errors.

Failure of the kernel part of the mapping operation should also be
indicated as an error to the caller, or else it may assume the
respective kernel VA is okay to access.
Furthermore gnttab_map_refs() failing still requires recording
successfully mapped handles, so they can be unmapped subsequently. This
in turn requires there to be a way to tell full hypercall failure from
partial success - preset map_op status fields such that they won't
"happen" to look as if the operation succeeded.
Also again use GNTST_okay instead of implying its value (zero).
This is part of XSA-361.

We may not skip setting the field in the unmap structure when
GNTMAP_device_map is in use - such an unmap would fail to release the
respective resources (a page ref in the hypervisor). Otoh the field
doesn't need setting at all when GNTMAP_device_map is not in use.
To record the value for unmapping, we also better don't use our local
p2m: In particular after a subsequent change it may not have got updated
for all the batch elements. Instead it can simply be taken from the
respective map's results.
We can additionally avoid playing this game altogether for the kernel
part of the mappings in (x86) PV mode.
