Various fixes for tracing:
- Fix tp_printk command line option crashing the kernel With the code that can handle a buffer from a previous boot, the trace_check_vprintf() needed access to the delta of the address space used by the old buffer and the current buffer. To do so, the trace_array (tr) parameter was used. But when tp_printk is enabled on the kernel command line, no trace buffer is used and the trace event is sent directly to printk(). That meant the tr field of the iterator descriptor was NULL, and since tp_printk still uses trace_check_vprintf() it caused a NULL dereference. - Add ptrace.h include to x86 ftrace file for completeness - Fix rtla installation when done with out-of-tree build - Fix the help messages in rtla that were incorrect - Several fixes to fix races with the timerlat and hwlat code Several locking issues were discovered with the coordination between timerlat kthread creation and hotplug. As timerlat has callbacks from hotplug code to start kthreads when CPUs come online. There are also locking issues with grabbing the cpu_read_lock() and the locks within timerlat. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCZwAUghQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qmMCAP9Z+0sN/Tx+F+5LmrXV1R9UxRPykmpm 4NeZYEp+hAQSegD+MdHsEJLIDfmsZnGOBivmzfepuv35GMLrqQMIhhWQOA0= =/OQq -----END PGP SIGNATURE----- Merge tag 'trace-v6.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing fixes from Steven Rostedt: - Fix tp_printk command line option crashing the kernel With the code that can handle a buffer from a previous boot, the trace_check_vprintf() needed access to the delta of the address space used by the old buffer and the current buffer.

Merge branch 'ibmvnic-fix-for-send-scrq-direct'
Nick Child says:
====================
ibmvnic: Fix for send scrq direct
This is a v2 of a patchset (now just patch) which addresses a
bug in a new feature which is causing major link UP issues with
certain physical cards.
For a full summary of the issue:
1. During vnic initialization we get the following values from vnic
server regarding "Transmit / Receive Descriptor Requirement" (see
PAPR Table 584. CAPABILITIES Commands):
- LSO Tx frame = 0x0F , header offsets + L2, L3, L4 headers required
- CSO Tx frame = 0x0C , header offsets + L2 header required
- standard frame = 0x0C , header offsets + L2 header required
2. Assume we are dealing with only "standard frames" from now on (no
CSO, no LSO)
3. When using 100G backing device, we don't hand vnic server any header
information and TX is successful
4. When using 25G backing device, we don't hand vnic server any header
information and TX fails and we get "Adapter Error" transport events.
The obvious issue here is that vnic client should be respecting the 0X0C
header requirement for standard frames. But 100G cards will also give
0x0C despite the fact that we know TX works if we ignore it. That being
said, we still must respect values given from the managing server. Will
need to work with them going forward to hopefully get 100G cards to
return 0x00 for this bitstring so the performance gains of using
send_subcrq_direct can be continued.

ibmvnic: Inspect header requirements before using scrq direct
Previously, the TX header requirement for standard frames was ignored.
This requirement is a bitstring sent from the VIOS which maps to the
type of header information needed during TX. If no header information,
is needed then send subcrq direct can be used (which can be more
performant).
This bitstring was previously ignored for standard packets (AKA non LSO,
non CSO) due to the belief that the bitstring was over-cautionary. It
turns out that there are some configurations where the backing device
does need header information for transmission of standard packets. If
the information is not supplied then this causes continuous "Adapter
error" transport events. Therefore, this bitstring should be respected
and observed before considering the use of send subcrq direct.

netfilter: br_netfilter: fix panic with metadata_dst skb
Fix a kernel panic in the br_netfilter module when sending untagged
traffic via a VxLAN device.
This happens during the check for fragmentation in br_nf_dev_queue_xmit.
It is dependent on:
1) the br_netfilter module being loaded;
2) net.bridge.bridge-nf-call-iptables set to 1;
3) a bridge with a VxLAN (single-vxlan-device) netdevice as a bridge port;
4) untagged frames with size higher than the VxLAN MTU forwarded/flooded
When forwarding the untagged packet to the VxLAN bridge port, before
the netfilter hooks are called, br_handle_egress_vlan_tunnel is called and
changes the skb_dst to the tunnel dst. The tunnel_dst is a metadata type
of dst, i.e., skb_valid_dst(skb) is false, and metadata->dst.dev is NULL.
Then in the br_netfilter hooks, in br_nf_dev_queue_xmit, there's a check
for frames that needs to be fragmented: frames with higher MTU than the
VxLAN device end up calling br_nf_ip_fragment, which in turns call
ip_skb_dst_mtu.
The ip_dst_mtu tries to use the skb_dst(skb) as if it was a valid dst
with valid dst->dev, thus the crash.
This case was never supported in the first place, so drop the packet
instead.

Merge branch 'add-option-to-provide-opt_id-value-via-cmsg'
Vadim Fedorenko says:
====================
Add option to provide OPT_ID value via cmsg
SOF_TIMESTAMPING_OPT_ID socket option flag gives a way to correlate TX
timestamps and packets sent via socket. Unfortunately, there is no way
to reliably predict socket timestamp ID value in case of error returned
by sendmsg. For UDP sockets it's impossible because of lockless
nature of UDP transmit, several threads may send packets in parallel. In
case of RAW sockets MSG_MORE option makes things complicated. More
details are in the conversation [1].
This patch adds new control message type to give user-space
software an opportunity to control the mapping between packets and
values by providing ID with each sendmsg.
The first patch in the series adds all needed definitions and implements
the function for UDP sockets. The explicit check of socket's type is not
added because subsequent patches in the series will add support for other
types of sockets. The documentation is also included into the first
patch.
Patch 2/4 adds support for TCP sockets. This part is simple and straight
forward.
Patch 3/4 adds support for RAW sockets. It's a bit tricky because
sock_tx_timestamp functions has to be refactored to receive full socket
cookie information to fill in ID. The commit

net_tstamp: add SCM_TS_OPT_ID for RAW sockets
The last type of sockets which supports SOF_TIMESTAMPING_OPT_ID is RAW sockets. To add new option this patch converts all callers (direct and indirect) of _sock_tx_timestamp to provide sockcm_cookie instead of tsflags. And while here fix __sock_tx_timestamp to receive tsflags as __u32 instead of __u16.

net_tstamp: add SCM_TS_OPT_ID to provide OPT_ID in control message
SOF_TIMESTAMPING_OPT_ID socket option flag gives a way to correlate TX timestamps and packets sent via socket. Unfortunately, there is no way to reliably predict socket timestamp ID value in case of error returned by sendmsg. For UDP sockets it's impossible because of lockless nature of UDP transmit, several threads may send packets in parallel. In case of RAW sockets MSG_MORE option makes things complicated. More details are in the conversation [1]. This patch adds new control message type to give user-space software an opportunity to control the mapping between packets and values by providing ID with each sendmsg for UDP sockets. The documentation is also added in this patch.

net/mlx5: hw counters: Don't maintain a counter count
num_counters is only used for deciding whether to grow the bulk query buffer, which is done once more counters than a small initial threshold are present. After that, maintaining num_counters serves no purpose. This commit replaces that with an actual xarray traversal to count the counters. This appears expensive at first sight, but is only done when the number of counters is less than the initial threshold (8) and only once every sampling interval. Once the number of counters goes above the threshold, the bulk query buffer is grown to max size and the xarray traversal is never done again.

net/mlx5: hw counters: Drop unneeded cacheline alignment
The mlx5_fc struct has a cache for values queried from hw, which is
cacheline aligned. On x86_64, this results in:
struct mlx5_fc {
u32 id; /* 0 4 */
bool aging; /* 4 1 */
/* XXX 3 bytes hole, try to pack */
struct mlx5_fc_bulk * bulk; /* 8 8 */
/* XXX 48 bytes hole, try to pack */
/* --- cacheline 1 boundary (64 bytes) --- */
struct mlx5_fc_cache cache __attribute__((__aligned__(64)));
/* 64 24 */
u64 lastpackets; /* 88 8 */
u64 lastbytes; /* 96 8 */
/* size: 128, cachelines: 2, members: 6 */
/* sum members: 53, holes: 2, sum holes: 51 */
/* padding: 24 */
/* forced aligns: 1, forced holes: 1, sum forced holes: 48 */
} __attribute__((__aligned__(64)));
(output from pahole).
...So a 48+24=72 byte waste. As far as I can determine, this serves no
purpose other than maybe making sure that the values in the cache do not
span two cachelines in the worst case scenario, but that's not a valid
enough reason to waste 72 bytes per counter, especially since this code
is not performance-critical. There could potentially be hundreds of
thousands of counters (e.g. for connection-tracking), so this quickly
adds up to multiple MB wasted.
This commit removes the alignment, resulting in:
struct mlx5_fc {
[...]
/* size: 56, cachelines: 1, members: 6 */
/* sum members: 53, holes: 1, sum holes: 3 */
/* last cacheline: 56 bytes */
};

net/mlx5: hw counters: Replace IDR+lists with xarray
Previously, managing counters was a complicated affair involving an IDR, a sorted double linked list, two single linked lists and a complex dance between a non-periodic wq task and users adding/deleting counters. Adding was done by inserting new counters into the IDR and into a single linked list, leaving the wq to process the list and actually add the counters into the double linked list, maintained sorted with the IDR. Deleting involved adding the counter into another single linked list, leaving the wq to actually unlink the counter from the other structures and release it. Dumping the counters is done with the bulk query API, which relies on the counter list being sorted and unmutable during querying to efficiently retrieve cached counter values. Finally, the IDR data struct is deprecated. This commit replaces all of that with an xarray. Adding is now done directly, by using xa_lock. Deleting is also done directly, under the xa_lock. Querying is done from a periodic task running every sampling_interval (default 1s) and uses the bulk query API for efficiency. It works by iterating over the xarray: - when a new bulk needs to be started, the bulk information is computed under the xa_lock. - the xa iteration state is saved and the xa_lock dropped. - the HW is queried for bulk counter values. - the xa_lock is reacquired. - counter caches with ids covered by the bulk response are updated. Querying always requests the max bulk length, for simplicity. Counters could be added/deleted while the HW is queried. This is safe, as the HW API simply returns unknown values for counters not in HW, but those values won't be accessed. Only counters present in xarray before bulk query will actually read queried cache values. This cuts down the size of mlx5_fc by 4 pointers (88->56 bytes), which amounts to ~3MB / 100K counters. But more importantly, this solves the wq spinlock congestion issue seen happening on high-rate counter insertion+deletion.

net/mlx5: hw counters: Use kvmalloc for bulk query buffer
The bulk query buffer starts out small (see [1]) and as soon as the
number of counters goes past the initial threshold grows to max
size (32K entries, 512KB) with a retry scheme.
This commit switches to using kvmalloc for the buffer, which has a near
zero likelihood of failing, and thus the explicit retry scheme becomes
superfluous and is taken out. On the low chance the allocation fails, it
will still be retried every sampling_interval, when the wq task runs.

net/mlx5: hw counters: Make fc_stats & fc_pool private
The mlx5_fc_stats and mlx5_fc_pool structs are only used from fs_counters.c. As such, make them private there. mlx5_fc_pool is not used or referenced at all outside fs_counters. mlx5_fc_stats is referenced from mlx5_core_dev, so instead of having it as a direct member (which requires exporting it from fs_counters), store a pointer to it, allocate it on init and clear it on destroy. One caveat is that a simple container_of to get from a 'work' struct to the outermost mlx5_core_dev struct directly no longer works, so an extra pointer had to be added to mlx5_fc_stats back to the parent dev.

net: dsa: sja1105: fix reception from VLAN-unaware bridges
The blamed commit introduced an unexpected regression in the sja1105
driver. Packets from VLAN-unaware bridge ports get received correctly,
but the protocol stack can't seem to decode them properly.
For ds->untag_bridge_pvid users (thus also sja1105), the blamed commit
did introduce a functional change: dsa_switch_rcv() used to call
dsa_untag_bridge_pvid(), which looked like this:
err = br_vlan_get_proto(br, &proto);
if (err)
return skb;
/* Move VLAN tag from data to hwaccel */
if (!skb_vlan_tag_present(skb) && skb->protocol == htons(proto)) {
skb = skb_vlan_untag(skb);
if (!skb)
return NULL;
}
and now it calls dsa_software_vlan_untag() which has just this:
/* Move VLAN tag from data to hwaccel */
if (!skb_vlan_tag_present(skb)) {
skb = skb_vlan_untag(skb);
if (!skb)
return NULL;
}
thus lacks any skb->protocol == bridge VLAN protocol check. That check
is deferred until a later check for skb->vlan_proto (in the hwaccel area).
The new code is problematic because, for VLAN-untagged packets,
skb_vlan_untag() blindly takes the 4 bytes starting with the EtherType
and turns them into a hwaccel VLAN tag. This is what breaks the protocol
stack.
It would be tempting to "make it work as before" and only call
skb_vlan_untag() for those packets with the skb->protocol actually
representing a VLAN.
But the premise of the newly introduced dsa_software_vlan_untag() core
function is not wrong. Drivers set ds->untag_bridge_pvid or
ds->untag_vlan_aware_bridge_pvid presumably because they send all
traffic to the CPU reception path as VLAN-tagged. So why should we spend
any additional CPU cycles assuming that the packet may be VLAN-untagged?
And why does the sja1105 driver opt into ds->untag_bridge_pvid if it
doesn't always deliver packets to the CPU as VLAN-tagged?
The answer to the latter question is indeed more interesting: it doesn't
need to. This got done in commit

thermal: core: Free tzp copy along with the thermal zone

thermal: core: Reference count the zone in thermal_zone_get_by_id()
There are places in the thermal netlink code where nothing prevents
the thermal zone object from going away while being accessed after it
has been returned by thermal_zone_get_by_id().
To address this, make thermal_zone_get_by_id() get a reference on the
thermal zone device object to be returned with the help of get_device(),
under thermal_list_lock, and adjust all of its callers to this change
with the help of the cleanup.h infrastructure.

Merge branch 'net-switch-to-scoped-device_for_each_child_node'
Javier Carrasco says: ==================== net: switch to scoped device_for_each_child_node() This series switches from the device_for_each_child_node() macro to its scoped variant. This makes the code more robust if new early exits are added to the loops, because there is no need for explicit calls to fwnode_handle_put(), which also simplifies existing code. The non-scoped macros to walk over nodes turn error-prone as soon as the loop contains early exits (break, goto, return), and patches to fix them show up regularly, sometimes due to new error paths in an existing loop [1]. Note that the child node is now declared in the macro, and therefore the explicit declaration is no longer required. The general functionality should not be affected by this modification. If functional changes are found, please report them back as errors.
