5be953e353 vdpa_sim: fix possible memory leak in vdpasim_net_init() and vdpasim_blk_init()
[ Upstream commit aeca7ff254 ]

Inject fault while probing module, if device_register() fails in
vdpasim_net_init() or vdpasim_blk_init(), but the refcount of kobject is
not decreased to 0, the name allocated in dev_set_name() is leaked.
Fix this by calling put_device(), so that name can be freed in
callback function kobject_cleanup().

8ee495a4c6 bnxt_en: Fix HDS and jumbo thresholds for RX packets
[ Upstream commit a056ebcc30 ]

The recent XDP multi-buffer feature has introduced regressions in the
setting of HDS and jumbo thresholds.  HDS was accidentally disabled in
the nornmal mode without XDP.  This patch restores jumbo HDS placement
when not in XDP mode.  In XDP multi-buffer mode, HDS should be disabled
and the jumbo threshold should be set to the usable page size in the
first page buffer.

4d3b78ca1f bnxt_en: Fix first buffer size calculations for XDP multi-buffer
[ Upstream commit 1abeacc197 ]

The size of the first buffer is always page size, and the useable
space is the page size minus the offset and the skb_shared_info size.
Make sure SKB and XDP buf sizes match so that the skb_shared_info
is at the same offset seen from the SKB and XDP_BUF.

build_skb() should be passed PAGE_SIZE.  xdp_init_buff() should
be passed PAGE_SIZE as well.  xdp_get_shared_info_from_buff() will
automatically deduct the skb_shared_info size if the XDP buffer
has frags.  There is no need to keep bp->xdp_has_frags.

Change BNXT_PAGE_MODE_BUF_SIZE to BNXT_MAX_PAGE_MODE_MTU_SBUF
since this constant is really the MTU with ethernet header size
subtracted.

Also fix the BNXT_MAX_PAGE_MODE_MTU macro with proper parentheses.

804e085008 net: dsa: mv88e6xxx: depend on PTP conditionally
[ Upstream commit 30e7255375 ]

PTP hardware timestamping related objects are not linked when PTP
support for MV88E6xxx (NET_DSA_MV88E6XXX_PTP) is disabled, therefore
NET_DSA_MV88E6XXX should not depend on PTP_1588_CLOCK_OPTIONAL
regardless of NET_DSA_MV88E6XXX_PTP.

Instead, condition more strictly on how NET_DSA_MV88E6XXX_PTP's
dependencies are met, making sure that it cannot be enabled when
NET_DSA_MV88E6XXX=y and PTP_1588_CLOCK=m.

In other words, this commit allows NET_DSA_MV88E6XXX to be built-in
while PTP_1588_CLOCK is a module, as long as NET_DSA_MV88E6XXX_PTP is
prevented from being enabled.

8df1dc04ce qlcnic: prevent ->dcb use-after-free on qlcnic_dcb_enable() failure
[ Upstream commit 13a7c8964a ]

adapter->dcb would get silently freed inside qlcnic_dcb_enable() in
case qlcnic_dcb_attach() would return an error, which always happens
under OOM conditions. This would lead to use-after-free because both
of the existing callers invoke qlcnic_dcb_get_info() on the obtained
pointer, which is potentially freed at that point.

Propagate errors from qlcnic_dcb_enable(), and instead free the dcb
pointer at callsite using qlcnic_dcb_free(). This also removes the now
unused qlcnic_clear_dcb_ops() helper, which was a simple wrapper around
kfree() also causing memory leaks for partially initialized dcb.

Found by Linux Verification Center (linuxtesting.org) with the SVACE
static analysis tool.

====================================

Kernel uses tcindex_change() to change an existing
filter properties.

Yet the problem is that, during the process of changing,
if `old_r` is retrieved from `p->perfect`, then
kernel uses tcindex_alloc_perfect_hash() to newly
allocate filter results, uses tcindex_filter_result_init()
to clear the old filter result, without destroying
its tcf_exts structure, which triggers the above memory leak.

To be more specific, there are only two source for the `old_r`,
according to the tcindex_lookup(). `old_r` is retrieved from
`p->perfect`, or `old_r` is retrieved from `p->h`.

  * If `old_r` is retrieved from `p->perfect`, kernel uses
tcindex_alloc_perfect_hash() to newly allocate the
filter results. Then `r` is assigned with `cp->perfect + handle`,
which is newly allocated. So condition `old_r && old_r != r` is
true in this situation, and kernel uses tcindex_filter_result_init()
to clear the old filter result, without destroying
its tcf_exts structure

  * If `old_r` is retrieved from `p->h`, then `p->perfect` is NULL
according to the tcindex_lookup(). Considering that `cp->h`
is directly copied from `p->h` and `p->perfect` is NULL,
`r` is assigned with `tcindex_lookup(cp, handle)`, whose value
should be the same as `old_r`, so condition `old_r && old_r != r`
is false in this situation, kernel ignores using
tcindex_filter_result_init() to clear the old filter result.

So only when `old_r` is retrieved from `p->perfect` does kernel use
tcindex_filter_result_init() to clear the old filter result, which
triggers the above memory leak.

Considering that there already exists a tc_filter_wq workqueue
to destroy the old tcindex_data by tcindex_partial_destroy_work()
at the end of tcindex_set_parms(), this patch solves
this memory leak bug by removing this old filter result
clearing part and delegating it to the tc_filter_wq workqueue.

Note that this patch doesn't introduce any other issues. If
`old_r` is retrieved from `p->perfect`, this patch just
delegates old filter result clearing part to the
tc_filter_wq workqueue; If `old_r` is retrieved from `p->h`,
kernel doesn't reach the old filter result clearing part, so
removing this part has no effect.

and Dmitry Vyukov]

9ae5bf0823 veth: Fix race with AF_XDP exposing old or uninitialized descriptors
[ Upstream commit fa349e396e ]

When AF_XDP is used on on a veth interface the RX ring is updated in two
steps.  veth_xdp_rcv() removes packet descriptors from the FILL ring
fills them and places them in the RX ring updating the cached_prod
pointer.  Later xdp_do_flush() syncs the RX ring prod pointer with the
cached_prod pointer allowing user-space to see the recently filled in
descriptors.  The rings are intended to be SPSC, however the existing
order in veth_poll allows the xdp_do_flush() to run concurrently with
another CPU creating a race condition that allows user-space to see old
or uninitialized descriptors in the RX ring.  This bug has been observed
in production systems.

To summarize, we are expecting this ordering:

CPU 0 __xsk_rcv_zc()
CPU 0 __xsk_map_flush()
CPU 2 __xsk_rcv_zc()
CPU 2 __xsk_map_flush()

But we are seeing this order:

CPU 0 __xsk_rcv_zc()
CPU 2 __xsk_rcv_zc()
CPU 0 __xsk_map_flush()
CPU 2 __xsk_map_flush()

This occurs because we rely on NAPI to ensure that only one napi_poll
handler is running at a time for the given veth receive queue.
napi_schedule_prep() will prevent multiple instances from getting
scheduled. However calling napi_complete_done() signals that this
napi_poll is complete and allows subsequent calls to
napi_schedule_prep() and __napi_schedule() to succeed in scheduling a
concurrent napi_poll before the xdp_do_flush() has been called.  For the
veth driver a concurrent call to napi_schedule_prep() and
__napi_schedule() can occur on a different CPU because the veth xmit
path can additionally schedule a napi_poll creating the race.

The fix as suggested by Magnus Karlsson, is to simply move the
xdp_do_flush() call before napi_complete_done().  This syncs the
producer ring pointers before another instance of napi_poll can be
scheduled on another CPU.  It will also slightly improve performance by
moving the flush closer to when the descriptors were placed in the
RX ring.

271dac5ff7 net: lan966x: Fix configuration of the PCS
[ Upstream commit d717f9474e ]

When the PCS was taken out of reset, we were changing by mistake also
the speed to 100 Mbit. But in case the link was going down, the link
up routine was setting correctly the link speed. If the link was not
getting down then the speed was forced to run at 100 even if the
speed was something else.
On lan966x, to set the speed link to 1G or 2.5G a value of 1 needs to be
written in DEV_CLOCK_CFG_LINK_SPEED. This is similar to the procedure in
lan966x_port_init.

The issue was reproduced using 1000base-x sfp module using the commands:
ip link set dev eth2 up
ip link addr add 10.97.10.2/24 dev eth2
ethtool -s eth2 speed 1000 autoneg off

The report is actually a false positive, since the only existing lock
nesting is the msk socket lock acquired by the mptcp work.
cancel_work_sync() is invoked without the relevant socket lock being
held, but under a different (the msk listener) socket lock.

We could silence the splat adding a per workqueue dynamic lockdep key,
but that looks overkill. Instead just tell lockdep the msk socket lock
is not held around cancel_work_sync().

be04181fd2 net: vrf: determine the dst using the original ifindex for multicast
[ Upstream commit f2575c8f40 ]

Multicast packets received on an interface bound to a VRF are marked as
belonging to the VRF and the skb device is updated to point to the VRF
device itself. This was fine even when a route was associated to a
device as when performing a fib table lookup 'oif' in fib6_table_lookup
(coming from 'skb->dev->ifindex' in ip6_route_input) was set to 0 when
FLOWI_FLAG_SKIP_NH_OIF was set.

With commit 40867d74c3 ("net: Add l3mdev index to flow struct and
avoid oif reset for port devices") this is not longer true and multicast
traffic is not received on the original interface.

Instead of adding back a similar check in fib6_table_lookup determine
the dst using the original ifindex for multicast VRF traffic. To make
things consistent across the function do the above for all strict
packets, which was the logic before commit 6f12fa7755 ("vrf: mark skb
for multicast or link-local as enslaved to VRF"). Note that reverting to
this behavior should be fine as the change was about marking packets
belonging to the VRF, not about their dst.

505d62e4c9 ice: xsk: do not use xdp_return_frame() on tx_buf->raw_buf
[ Upstream commit 53fc61be27 ]

Previously ice XDP xmit routine was changed in a way that it avoids
xdp_buff->xdp_frame conversion as it is simply not needed for handling
XDP_TX action and what is more it saves us CPU cycles. This routine is
re-used on ZC driver to handle XDP_TX action.

Although for XDP_TX on Rx ZC xdp_buff that comes from xsk_buff_pool is
converted to xdp_frame, xdp_frame itself is not stored inside
ice_tx_buf, we only store raw data pointer. Casting this pointer to
xdp_frame and calling against it xdp_return_frame in
ice_clean_xdp_tx_buf() results in undefined behavior.

To fix this, simply call page_frag_free() on tx_buf->raw_buf.
Later intention is to remove the buff->frame conversion in order to
simplify the codebase and improve XDP_TX performance on ZC.

8f679a0830 netfilter: nf_tables: perform type checking for existing sets
[ Upstream commit f6594c372a ]

If a ruleset declares a set name that matches an existing set in the
kernel, then validate that this declaration really refers to the same
set, otherwise bail out with EEXIST.

Currently, the kernel reports success when adding a set that already
exists in the kernel. This usually results in EINVAL errors at a later
stage, when the user adds elements to the set, if the set declaration
mismatches the existing set representation in the kernel.

Add a new function to check that the set declaration really refers to
the same existing set in the kernel.

3f9feffa8a drm/panfrost: Fix GEM handle creation ref-counting
[ Upstream commit 4217c6ac81 ]

panfrost_gem_create_with_handle() previously returned a BO but with the
only reference being from the handle, which user space could in theory
guess and release, causing a use-after-free. Additionally if the call to
panfrost_gem_mapping_get() in panfrost_ioctl_create_bo() failed then
a(nother) reference on the BO was dropped.

The _create_with_handle() is a problematic pattern, so ditch it and
instead create the handle in panfrost_ioctl_create_bo(). If the call to
panfrost_gem_mapping_get() fails then this means that user space has
indeed gone behind our back and freed the handle. In which case just
return an error code.

2ee0be3fa1 SUNRPC: ensure the matching upcall is in-flight upon downcall
[ Upstream commit b18cba09e3 ]

Commit 9130b8dbc6 ("SUNRPC: allow for upcalls for the same uid
but different gss service") introduced `auth` argument to
__gss_find_upcall(), but in gss_pipe_downcall() it was left as NULL
since it (and auth->service) was not (yet) determined.

When multiple upcalls with the same uid and different service are
ongoing, it could happen that __gss_find_upcall(), which returns the
first match found in the pipe->in_downcall list, could not find the
correct gss_msg corresponding to the downcall we are looking for.
Moreover, it might return a msg which is not sent to rpc.gssd yet.

We could see mount.nfs process hung in D state with multiple mount.nfs
are executed in parallel.  The call trace below is of CentOS 7.9
kernel-3.10.0-1160.24.1.el7.x86_64 but we observed the same hang w/
elrepo kernel-ml-6.0.7-1.el7.

PID: 71258  TASK: ffff91ebd4be0000  CPU: 36  COMMAND: "mount.nfs"
 #0 [ffff9203ca3234f8] __schedule at ffffffffa3b8899f

 #4 [ffff9203ca3236d8] gss_lookup_cred at ffffffffc0353633 [auth_rpcgss]
 #5 [ffff9203ca3236e8] rpcauth_lookupcred at ffffffffc0421581 [sunrpc]
 #6 [ffff9203ca323740] rpcauth_refreshcred at ffffffffc04223d3 [sunrpc]

 #9 [ffff9203ca323820] rpc_execute at ffffffffc0420a48 [sunrpc]

The scenario is like this. Let's say there are two upcalls for
services A and B, A -> B in pipe->in_downcall, B -> A in pipe->pipe.

When rpc.gssd reads pipe to get the upcall msg corresponding to
service B from pipe->pipe and then writes the response, in
gss_pipe_downcall the msg corresponding to service A will be picked
because only uid is used to find the msg and it is before the one for
B in pipe->in_downcall.  And the process waiting for the msg
corresponding to service A will be woken up.

Actual scheduing of that process might be after rpc.gssd processes the
next msg.  In rpc_pipe_generic_upcall it clears msg->errno (for A).
The process is scheduled to see gss_msg->ctx == NULL and
gss_msg->msg.errno == 0, therefore it cannot break the loop in
gss_create_upcall and is never woken up after that.

This patch adds a simple check to ensure that a msg which is not
sent to rpc.gssd yet is not chosen as the matching upcall upon
receiving a downcall.

ad8dc47585 ext4: correct inconsistent error msg in nojournal mode
[ Upstream commit 89481b5fa8 ]

When we used the journal_async_commit mounting option in nojournal mode,
the kernel told me that "can't mount with journal_checksum", was very
confusing. I find that when we mount with journal_async_commit, both the
JOURNAL_ASYNC_COMMIT and EXPLICIT_JOURNAL_CHECKSUM flags are set. However,
in the error branch, CHECKSUM is checked before ASYNC_COMMIT. As a result,
the above inconsistency occurs, and the ASYNC_COMMIT branch becomes dead
code that cannot be executed. Therefore, we exchange the positions of the
two judgments to make the error msg more accurate.

xattr cache. So the right label to goto is 'failed_mount3a'. Although
this did not cause any issues because the error handler validated if the
pointer is null. However this still made me confused when reading
the code. So it's still worth to modify to goto the right label.

906f421ac5 phy: qcom-qmp-combo: fix broken power on
[ Upstream commit 7a7d86d14d ]

The PHY is powered on during phy-init by setting the SW_PWRDN bit in the
COM_POWER_DOWN_CTRL register and then setting the same bit in the in the
PCS_POWER_DOWN_CONTROL register that belongs to the USB part of the
PHY.

Currently, whether power on succeeds depends on probe order and having
the USB part of the PHY be initialised first. In case the DP part of the
PHY is instead initialised first, the intended power on of the USB block
results in a corrupted DP_PHY register (e.g. DP_PHY_AUX_CFG8).

Add a pointer to the USB part of the PHY to the driver data and use that
to power on the PHY also if the DP part of the PHY is initialised first.

749fa62e49 perf probe: Fix to get the DW_AT_decl_file and DW_AT_call_file as unsinged data
[ Upstream commit a9dfc46c67 ]

DWARF version 5 standard Sec 2.14 says that

  Any debugging information entry representing the declaration of an object,
  module, subprogram or type may have DW_AT_decl_file, DW_AT_decl_line and
  DW_AT_decl_column attributes, each of whose value is an unsigned integer
  constant.

So it should be an unsigned integer data. Also, even though the standard
doesn't clearly say the DW_AT_call_file is signed or unsigned, the
elfutils (eu-readelf) interprets it as unsigned integer data and it is
natural to handle it as unsigned integer data as same as DW_AT_decl_file.
This changes the DW_AT_call_file as unsigned integer data too.

04116912f2 usb: dwc3: gadget: Ignore End Transfer delay on teardown
commit c4e3ef5685 upstream.

If we delay sending End Transfer for Setup TRB to be prepared, we need
to check if the End Transfer was in preparation for a driver
teardown/soft-disconnect. In those cases, just send the End Transfer
command without delay.

In the case of soft-disconnect, there's a very small chance the command
may not go through immediately. But should it happen, the Setup TRB will
be prepared during the polling of the controller halted state, allowing
the command to go through then.

In the case of disabling endpoint due to reconfiguration (e.g.
set_interface(alt-setting) or usb reset), then it's driven by the host.
Typically the host wouldn't immediately cancel the control request and
send another control transfer to trigger the End Transfer command
timeout.

00e2fad019 cifs: refcount only the selected iface during interface update
commit 7246210ecd upstream.

When the server interface for a channel is not active anymore,
we have the logic to select an alternative interface. However
this was not breaking out of the loop as soon as a new alternative
was found. As a result, some interfaces may get refcounted unintentionally.

There was also a bug in checking if we found an alternate iface.
Fixed that too.

9f9748bbe8 drm/i915: improve the catch-all evict to handle lock contention
commit 3f882f2d4f upstream.

The catch-all evict can fail due to object lock contention, since it
only goes as far as trylocking the object, due to us already holding the
vm->mutex. Doing a full object lock here can deadlock, since the
vm->mutex is always our inner lock. Add another execbuf pass which drops
the vm->mutex and then tries to grab the object will the full lock,
before then retrying the eviction. This should be good enough for now to
fix the immediate regression with userspace seeing -ENOSPC from execbuf
due to contended object locks during GTT eviction.

v2 (Mani)
  - Also revamp the docs for the different passes.
