tracefs/eventfs fixes and updates for v6.10:
Bug fixes:
- The eventfs directories need to have unique inode numbers. Make sure that
they do not get the default file inode number.
- Update the inode uid and gid fields on remount.
When a remount happens where a uid and/or gid is specified, all the tracefs
files and directories should get the specified uid and/or gid. But this
can be sporadic when some uids were assigned already. There's already
a list of inodes that are allocated. Just update their uid and gid fields
at the time of remount.
- Update the eventfs_inodes on remount from the top level "events" descriptor.
There was a bug where not all the eventfs files or directories where
getting updated on remount. One fix was to clear the SAVED_UID/GID
flags from the inode list during the iteration of the inodes during
the remount. But because the eventfs inodes can be freed when the last
referenced is released, not all the eventfs_inodes were being updated.
This lead to the ownership selftest to fail if it was run a second
time (the first time would leave eventfs_inodes with no corresponding
tracefs_inode).
Instead, for eventfs_inodes, only process the "events" eventfs_inode
from the list iteration, as it is guaranteed to have a tracefs_inode
(it's never freed while the "events" directory exists). As it has
a list of its children, and the children have a list of their children,
just iterate all the eventfs_inodes from the "events" descriptor and
it is guaranteed to get all of them.
- Clear the EVENT_INODE flag from the tracefs_drop_inode() callback.
Currently the EVENTFS_INODE FLAG is cleared in the tracefs_d_iput()
callback. But this is the wrong location. The iput() callback is
called when the last reference to the dentry inode is hit. There could
be a case where two dentry's have the same inode, and the flag will
be cleared prematurely. The flag needs to be cleared when the last
reference of the inode is dropped and that happens in the inode's
drop_inode() callback handler.
Clean ups:
- Consolidate the creation of a tracefs_inode for an eventfs_inode
A tracefs_inode is created for both files and directories of the
eventfs system. It is open coded. Instead, consolidate it into a
single eventfs_get_inode() function call.
- Remove the eventfs getattr and permission callbacks.
The permissions for the eventfs files and directories are updated
when the inodes are created, on remount, and when the user sets
them (via setattr). The inodes hold the current permissions so
there is no need to have custom getattr or permissions callbacks
as they will more likely cause them to be incorrect. The inode's
permissions are updated when they should be updated. Remove the
getattr and permissions inode callbacks.
- Do not update eventfs_inode attributes on creation of inodes.
The eventfs_inodes attribute field is used to store the permissions
of the directories and files for when their corresponding inodes
are freed and are created again. But when the creation of the inodes
happen, the eventfs_inode attributes are recalculated. The
recalculation should only happen when the permissions change for
a given file or directory. Currently, the attribute changes are
just being set to their current files so this is not a bug, but
it's unnecessary and error prone. Stop doing that.
- The events directory inode is created once when the events directory
is created and deleted when it is deleted. It is now updated on
remount and when the user changes the permissions. There's no need
to use the eventfs_inode of the events directory to store the
events directory permissions. But using it to store the default
permissions for the files within the directory that have not been
updated by the user can simplify the code.

selftest to fail if it was run a second time (the first time would
leave eventfs_inodes with no corresponding tracefs_inode).
Instead, for eventfs_inodes, only process the "events"
eventfs_inode from the list iteration, as it is guaranteed to have
a tracefs_inode (it's never freed while the "events" directory
exists). As it has a list of its children, and the children have a
list of their children, just iterate all the eventfs_inodes from
the "events" descriptor and it is guaranteed to get all of them.
- Clear the EVENT_INODE flag from the tracefs_drop_inode() callback.
Currently the EVENTFS_INODE FLAG is cleared in the tracefs_d_iput()
callback. But this is the wrong location. The iput() callback is
called when the last reference to the dentry inode is hit. There
could be a case where two dentry's have the same inode, and the
flag will be cleared prematurely. The flag needs to be cleared when
the last reference of the inode is dropped and that happens in the
inode's drop_inode() callback handler.
Cleanups:
- Consolidate the creation of a tracefs_inode for an eventfs_inode
A tracefs_inode is created for both files and directories of the
eventfs system. It is open coded. Instead, consolidate it into a
single eventfs_get_inode() function call.
- Remove the eventfs getattr and permission callbacks.
The permissions for the eventfs files and directories are updated
when the inodes are created, on remount, and when the user sets
them (via setattr). The inodes hold the current permissions so
there is no need to have custom getattr or permissions callbacks as
they will more likely cause them to be incorrect. The inode's
permissions are updated when they should be updated. Remove the
getattr and permissions inode callbacks.
- Do not update eventfs_inode attributes on creation of inodes.
The eventfs_inodes attribute field is used to store the permissions
of the directories and files for when their corresponding inodes
are freed and are created again. But when the creation of the
inodes happen, the eventfs_inode attributes are recalculated. The
recalculation should only happen when the permissions change for a
given file or directory. Currently, the attribute changes are just
being set to their current files so this is not a bug, but it's
unnecessary and error prone. Stop doing that.
- The events directory inode is created once when the events
directory is created and deleted when it is deleted. It is now
updated on remount and when the user changes the permissions.
There's no need to use the eventfs_inode of the events directory to
store the events directory permissions. But using it to store the
default permissions for the files within the directory that have
not been updated by the user can simplify the code"

tracing: Remove second argument of __assign_str()
The __assign_str() macro logic of the TRACE_EVENT() macro was optimized so that it no longer needs the second argument. The __assign_str() is always matched with __string() field that takes a field name and the source for that field: __string(field, source) The TRACE_EVENT() macro logic will save off the source value and then use that value to copy into the ring buffer via the __assign_str().

r8169: Fix possible ring buffer corruption on fragmented Tx packets.
An issue was found on the RTL8125b when transmitting small fragmented
packets, whereby invalid entries were inserted into the transmit ring
buffer, subsequently leading to calls to dma_unmap_single() with a null
address.
This was caused by rtl8169_start_xmit() not noticing changes to nr_frags
which may occur when small packets are padded (to work around hardware
quirks) in rtl8169_tso_csum_v2().
To fix this, postpone inspecting nr_frags until after any padding has been
applied.

eventfs: Do not use attributes for events directory
The top "events" directory has a static inode (it's created when it is and removed when the directory is removed). There's no need to use the events ei->attr to determine its permissions. But it is used for saving the permissions of the "events" directory for when it is created, as that is needed for the default permissions for the files and directories underneath it. For example: # cd /sys/kernel/tracing # mkdir instances/foo # chown 1001 instances/foo/events The files under instances/foo/events should still have the same owner as instances/foo (which the instances/foo/events ei->attr will hold), but the events directory now has owner 1001.

eventfs: Cleanup permissions in creation of inodes
The permissions being set during the creation of the inodes was updating
eventfs_inode attributes as well. Those attributes should only be touched
by the setattr or remount operations, not during the creation of inodes.
The eventfs_inode attributes should only be used to set the inodes and
should not be modified during the inode creation.
Simplify the code and fix the situation by:
1) Removing the eventfs_find_events() and doing a simple lookup for
the events descriptor in eventfs_get_inode()
2) Remove update_events_attr() as the attributes should only be used
to update the inode and should not be modified here.
3) Add update_inode_attr() that uses the attributes to determine what
the inode permissions should be.
4) As the parent_inode of the eventfs_root_inode structure is no longer
needed, remove it.
Now on creation, the inode gets the proper permissions without causing
side effects to the ei->attr field.

eventfs: Remove getattr and permission callbacks
Now that inodes have their permissions updated on remount, the only other places to update the inode permissions are when they are created and in the setattr callback. The getattr and permission callbacks are not needed as the inodes should already be set at their proper settings. Remove the callbacks, as it not only simplifies the code, but also allows more flexibility to fix the inconsistencies with various corner cases (like changing the permission of an instance directory).

tracefs: Clear EVENT_INODE flag in tracefs_drop_inode()
When the inode is being dropped from the dentry, the TRACEFS_EVENT_INODE
flag needs to be cleared to prevent a remount from calling
eventfs_remount() on the tracefs_inode private data. There's a race
between the inode is dropped (and the dentry freed) to where the inode is
actually freed. If a remount happens between the two, the eventfs_inode
could be accessed after it is freed (only the dentry keeps a ref count on
it).
Currently the TRACEFS_EVENT_INODE flag is cleared from the dentry iput()
function. But this is incorrect, as it is possible that the inode has
another reference to it. The flag should only be cleared when the inode is
really being dropped and has no more references. That happens in the
drop_inode callback of the inode, as that gets called when the last
reference of the inode is released.
Remove the tracefs_d_iput() function and move its logic to the more
appropriate tracefs_drop_inode() callback function.

eventfs: Update all the eventfs_inodes from the events descriptor
The change to update the permissions of the eventfs_inode had the
misconception that using the tracefs_inode would find all the
eventfs_inodes that have been updated and reset them on remount.
The problem with this approach is that the eventfs_inodes are freed when
they are no longer used (basically the reason the eventfs system exists).
When they are freed, the updated eventfs_inodes are not reset on a remount
because their tracefs_inodes have been freed.
Instead, since the events directory eventfs_inode always has a
tracefs_inode pointing to it (it is not freed when finished), and the
events directory has a link to all its children, have the
eventfs_remount() function only operate on the events eventfs_inode and
have it descend into its children updating their uid and gids.

Merge branch 'intel-interpret-set_channels-input-differently'
Jacob Keller says:
====================
intel: Interpret .set_channels() input differently
The ice and idpf drivers can trigger a crash with AF_XDP due to incorrect
interpretation of the asymmetric Tx and Rx parameters in their
.set_channels() implementations:
1. ethtool -l <IFNAME> -> combined: 40
2. Attach AF_XDP to queue 30
3. ethtool -L <IFNAME> rx 15 tx 15
combined number is not specified, so command becomes {rx_count = 15,
tx_count = 15, combined_count = 40}.
4. ethnl_set_channels checks, if there are any AF_XDP of queues from the
new (combined_count + rx_count) to the old one, so from 55 to 40, check
does not trigger.
5. the driver interprets `rx 15 tx 15` as 15 combined channels and deletes
the queue that AF_XDP is attached to.
This is fundamentally a problem with interpreting a request for asymmetric
queues as symmetric combined queues.
Fix the ice and idpf drivers to stop interpreting such requests as a
request for combined queues. Due to current driver design for both ice and
idpf, it is not possible to support requests of the same count of Tx and Rx
queues with independent interrupts, (i.e. ethtool -L <IFNAME> rx 15 tx 15)
so such requests are now rejected.

idpf: Interpret .set_channels() input differently
Unlike ice, idpf does not check, if user has requested at least 1 combined
channel. Instead, it relies on a check in the core code. Unfortunately, the
check does not trigger for us because of the hacky .set_channels()
interpretation logic that is not consistent with the core code.
This naturally leads to user being able to trigger a crash with an invalid
input. This is how:
1. ethtool -l <IFNAME> -> combined: 40
2. ethtool -L <IFNAME> rx 0 tx 0
combined number is not specified, so command becomes {rx_count = 0,
tx_count = 0, combined_count = 40}.
3. ethnl_set_channels checks, if there is at least 1 RX and 1 TX channel,
comparing (combined_count + rx_count) and (combined_count + tx_count)
to zero. Obviously, (40 + 0) is greater than zero, so the core code
deems the input OK.
4. idpf interprets `rx 0 tx 0` as 0 channels and tries to proceed with such
configuration.
The issue has to be solved fundamentally, as current logic is also known to
cause AF_XDP problems in ice [0].
Interpret the command in a way that is more consistent with ethtool
manual [1] (--show-channels and --set-channels) and new ice logic.
Considering that in the idpf driver only the difference between RX and TX
queues forms dedicated channels, change the correct way to set number of
channels to:
ethtool -L <IFNAME> combined 10 /* For symmetric queues */
ethtool -L <IFNAME> combined 8 tx 2 rx 0 /* For asymmetric queues */

ice: Interpret .set_channels() input differently
A bug occurs because a safety check guarding AF_XDP-related queues in

ice driver interpret the ethtool command differently.
How the bug occurs:
1. ethtool -l <IFNAME> -> combined: 40
2. Attach AF_XDP to queue 30
3. ethtool -L <IFNAME> rx 15 tx 15

nfc: nci: Fix handling of zero-length payload packets in nci_rx_work()
When nci_rx_work() receives a zero-length payload packet, it should not
discard the packet and exit the loop. Instead, it should continue
processing subsequent packets.

net: ti: icssg_prueth: Fix NULL pointer dereference in prueth_probe()
In the prueth_probe() function, if one of the calls to emac_phy_connect()
fails due to of_phy_connect() returning NULL, then the subsequent call to
phy_attached_info() will dereference a NULL pointer.
Check the return code of emac_phy_connect and fail cleanly if there is an
error.

tls: fix missing memory barrier in tls_init
In tls_init(), a write memory barrier is missing, and store-store
reordering may cause NULL dereference in tls_{setsockopt,getsockopt}.
CPU0 CPU1
----- -----
// In tls_init()
// In tls_ctx_create()
ctx = kzalloc()
ctx->sk_proto = READ_ONCE(sk->sk_prot) -(1)
// In update_sk_prot()
WRITE_ONCE(sk->sk_prot, tls_prots) -(2)
// In sock_common_setsockopt()
READ_ONCE(sk->sk_prot)->setsockopt()
// In tls_{setsockopt,getsockopt}()
ctx->sk_proto->setsockopt() -(3)
In the above scenario, when (1) and (2) are reordered, (3) can observe
the NULL value of ctx->sk_proto, causing NULL dereference.
To fix it, we rely on rcu_assign_pointer() which implies the release
barrier semantic. By moving rcu_assign_pointer() after ctx->sk_proto is
initialized, we can ensure that ctx->sk_proto are visible when
changing sk->sk_prot.

net: fec: avoid lock evasion when reading pps_enable
The assignment of pps_enable is protected by tmreg_lock, but the read
operation of pps_enable is not. So the Coverity tool reports a lock
evasion warning which may cause data race to occur when running in a
multithread environment. Although this issue is almost impossible to
occur, we'd better fix it, at least it seems more logically reasonable,
and it also prevents Coverity from continuing to issue warnings.

testing: net-drv: use stats64 for testing
Testing a network device that has large numbers of bytes/packets may
overflow. Using stats64 when comparing fixes this problem.
I tripped on this while iterating on a qstats patch for mlx5. See below
for confirmation without my added code that this is a bug.
Before this patch (with added debugging output):
$ NETIF=eth0 tools/testing/selftests/drivers/net/stats.py
KTAP version 1
1..4
ok 1 stats.check_pause
ok 2 stats.check_fec
rstat: 481708634 qstat: 666201639514 key: tx-bytes
not ok 3 stats.pkt_byte_sum
ok 4 stats.qstat_by_ifindex
Note the huge delta above ^^^ in the rtnl vs qstats.
After this patch:
$ NETIF=eth0 tools/testing/selftests/drivers/net/stats.py
KTAP version 1
1..4
ok 1 stats.check_pause
ok 2 stats.check_fec
ok 3 stats.pkt_byte_sum
ok 4 stats.qstat_by_ifindex
It looks like rtnl_fill_stats in net/core/rtnetlink.c will attempt to
copy the 64bit stats into a 32bit structure which is probably why this
behavior is occurring.
To show this is happening, you can get the underlying stats that the
stats.py test uses like this:
$ ./cli.py --spec ../../../Documentation/netlink/specs/rt_link.yaml \
--do getlink --json '{"ifi-index": 7}'
And examine the output (heavily snipped to show relevant fields):
'stats': {
'multicast': 3739197,
'rx-bytes': 1201525399,
'rx-packets': 56807158,
'tx-bytes': 492404458,
'tx-packets': 1200285371,
'stats64': {
'multicast': 3739197,
'rx-bytes': 35561263767,
'rx-packets': 56807158,
'tx-bytes': 666212335338,
'tx-packets': 1200285371,
The stats.py test prior to this patch was using the 'stats' structure
above, which matches the failure output on my system.
Comparing side by side, rx-bytes and tx-bytes, and getting ethtool -S
output:
rx-bytes stats: 1201525399
rx-bytes stats64: 35561263767
rx-bytes ethtool: 36203402638
tx-bytes stats: 492404458
tx-bytes stats64: 666212335338
tx-bytes ethtool: 666215360113
Note that the above was taken from a system with an mlx5 NIC, which only
exposes ndo_get_stats64.
Based on the ethtool output and qstat output, it appears that stats.py
should be updated to use the 'stats64' structure for accurate
comparisons when packet/byte counters get very large.
To confirm that this was not related to the qstats code I was iterating
on, I booted a kernel without my driver changes and re-ran the test
which shows the qstats are skipped (as they don't exist for mlx5):
NETIF=eth0 tools/testing/selftests/drivers/net/stats.py
KTAP version 1
1..4
ok 1 stats.check_pause
ok 2 stats.check_fec
ok 3 stats.pkt_byte_sum # SKIP qstats not supported by the device
ok 4 stats.qstat_by_ifindex # SKIP No ifindex supports qstats
But, fetching the stats using the CLI
$ ./cli.py --spec ../../../Documentation/netlink/specs/rt_link.yaml \
--do getlink --json '{"ifi-index": 7}'
Shows the same issue (heavily snipped for relevant fields only):
'stats': {
'multicast': 105489,
'rx-bytes': 530879526,
'rx-packets': 751415,
'tx-bytes': 2510191396,
'tx-packets': 27700323,
'stats64': {
'multicast': 105489,
'rx-bytes': 530879526,
'rx-packets': 751415,
'tx-bytes': 15395093284,
'tx-packets': 27700323,
Comparing side by side with ethtool -S on the unmodified mlx5 driver:
tx-bytes stats: 2510191396
tx-bytes stats64: 15395093284
tx-bytes ethtool: 17718435810
