tracing and tracefs fixes for v6.9
- Fix RCU callback of freeing an eventfs_inode. The freeing of the eventfs_inode from the kref going to zero freed the contents of the eventfs_inode and then used kfree_rcu() to free the inode itself. But the contents should also be protected by RCU. Switch to a call_rcu() that calls a function to free all of the eventfs_inode after the RCU synchronization. - The tracing subsystem maps its own descriptor to a file represented by eventfs. The freeing of this descriptor needs to know when the last reference of an eventfs_inode is released, but currently there is no interface for that. Add a "release" callback to the eventfs_inode entry array that allows for freeing of data that can be referenced by the eventfs_inode being opened. Then increment the ref counter for this descriptor when the eventfs_inode file is created, and decrement/free it when the last reference to the eventfs_inode is released and the file is removed. This prevents races between freeing the descriptor and the opening of the eventfs file. - Fix the permission processing of eventfs. The change to make the permissions of eventfs default to the mount point but keep track of when changes were made had a side effect that could cause security concerns. When the tracefs is remounted with a given gid or uid, all the files within it should inherit that gid or uid. But if the admin had changed the permission of some file within the tracefs file system, it would not get updated by the remount. This caused the kselftest of file permissions to fail the second time it is run. The first time, all changes would look fine, but the second time, because the changes were "saved", the remount did not reset them. Create a link list of all existing tracefs inodes, and clear the saved flags on them on a remount if the remount changes the corresponding gid or uid fields. This also simplifies the code by removing the distinction between the toplevel eventfs and an instance eventfs. They should both act the same. They were different because of a misconception due to the remount not resetting the flags. Now that remount resets all the files and directories to default to the root node if a uid/gid is specified, it makes the logic simpler to implement. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCZjXxzxQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qqzGAQCX8g7gtngGgwSsWqPW5GmecCifwFja k7cVEDhMYPnDeAEAkYi2ZBgJRkPsWPfMRClDK/DXP4woOo58asxtIxfTMgg= =mCkt -----END PGP SIGNATURE----- Merge tag 'trace-v6.9-rc6-2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing and tracefs fixes from Steven Rostedt: - Fix RCU callback of freeing an eventfs_inode.

eventfs: Have "events" directory get permissions from its parent
The events directory gets its permissions from the root inode. But this
can cause an inconsistency if the instances directory changes its
permissions, as the permissions of the created directories under it should
inherit the permissions of the instances directory when directories under
it are created.
Currently the behavior is:
# cd /sys/kernel/tracing
# chgrp 1002 instances
# mkdir instances/foo
# ls -l instances/foo
[..]
-r--r----- 1 root lkp 0 May 1 18:55 buffer_total_size_kb
-rw-r----- 1 root lkp 0 May 1 18:55 current_tracer
-rw-r----- 1 root lkp 0 May 1 18:55 error_log
drwxr-xr-x 1 root root 0 May 1 18:55 events
--w------- 1 root lkp 0 May 1 18:55 free_buffer
drwxr-x--- 2 root lkp 0 May 1 18:55 options
drwxr-x--- 10 root lkp 0 May 1 18:55 per_cpu
-rw-r----- 1 root lkp 0 May 1 18:55 set_event
All the files and directories under "foo" has the "lkp" group except the
"events" directory. That's because its getting its default value from the
mount point instead of its parent.
Have the "events" directory make its default value based on its parent's
permissions. That now gives:
# ls -l instances/foo
[..]
-rw-r----- 1 root lkp 0 May 1 21:16 buffer_subbuf_size_kb
-r--r----- 1 root lkp 0 May 1 21:16 buffer_total_size_kb
-rw-r----- 1 root lkp 0 May 1 21:16 current_tracer

eventfs: Do not treat events directory different than other directories
Treat the events directory the same as other directories when it comes to
permissions. The events directory was considered different because it's
dentry is persistent, whereas the other directory dentries are created
when accessed. But the way tracefs now does its ownership by using the
root dentry's permissions as the default permissions, the events directory
can get out of sync when a remount is performed setting the group and user
permissions.
Remove the special case for the events directory on setting the
attributes. This allows the updates caused by remount to work properly as
well as simplifies the code.

tracefs: Still use mount point as default permissions for instances
If the instances directory's permissions were never change, then have it
and its children use the mount point permissions as the default.
Currently, the permissions of instance directories are determined by the
instance directory's permissions itself. But if the tracefs file system is
remounted and changes the permissions, the instance directory and its
children should use the new permission.
But because both the instance directory and its children use the instance
directory's inode for permissions, it misses the update.
To demonstrate this:
# cd /sys/kernel/tracing/
# mkdir instances/foo
# ls -ld instances/foo
drwxr-x--- 5 root root 0 May 1 19:07 instances/foo
# ls -ld instances
drwxr-x--- 3 root root 0 May 1 18:57 instances
# ls -ld current_tracer
-rw-r----- 1 root root 0 May 1 18:57 current_tracer
# mount -o remount,gid=1002 .
# ls -ld instances
drwxr-x--- 3 root root 0 May 1 18:57 instances
# ls -ld instances/foo/
drwxr-x--- 5 root root 0 May 1 19:07 instances/foo/
# ls -ld current_tracer
-rw-r----- 1 root lkp 0 May 1 18:57 current_tracer
Notice that changing the group id to that of "lkp" did not affect the
instances directory nor its children. It should have been:
# ls -ld current_tracer
-rw-r----- 1 root root 0 May 1 19:19 current_tracer
# ls -ld instances/foo/
drwxr-x--- 5 root root 0 May 1 19:25 instances/foo/
# ls -ld instances
drwxr-x--- 3 root root 0 May 1 19:19 instances
# mount -o remount,gid=1002 .
# ls -ld current_tracer
-rw-r----- 1 root lkp 0 May 1 19:19 current_tracer
# ls -ld instances
drwxr-x--- 3 root lkp 0 May 1 19:19 instances
# ls -ld instances/foo/
drwxr-x--- 5 root lkp 0 May 1 19:25 instances/foo/
Where all files were updated by the remount gid update.

tracefs: Reset permissions on remount if permissions are options
There's an inconsistency with the way permissions are handled in tracefs.
Because the permissions are generated when accessed, they default to the
root inode's permission if they were never set by the user. If the user
sets the permissions, then a flag is set and the permissions are saved via
the inode (for tracefs files) or an internal attribute field (for
eventfs).
But if a remount happens that specify the permissions, all the files that
were not changed by the user gets updated, but the ones that were are not.
If the user were to remount the file system with a given permission, then
all files and directories within that file system should be updated.
This can cause security issues if a file's permission was updated but the
admin forgot about it. They could incorrectly think that remounting with
permissions set would update all files, but miss some.
For example:
# cd /sys/kernel/tracing
# chgrp 1002 current_tracer
# ls -l
[..]
-rw-r----- 1 root root 0 May 1 21:25 buffer_size_kb
-rw-r----- 1 root root 0 May 1 21:25 buffer_subbuf_size_kb
-r--r----- 1 root root 0 May 1 21:25 buffer_total_size_kb
-rw-r----- 1 root lkp 0 May 1 21:25 current_tracer
-rw-r----- 1 root root 0 May 1 21:25 dynamic_events
-r--r----- 1 root root 0 May 1 21:25 dyn_ftrace_total_info
-r--r----- 1 root root 0 May 1 21:25 enabled_functions
Where current_tracer now has group "lkp".
# mount -o remount,gid=1001 .
# ls -l
-rw-r----- 1 root tracing 0 May 1 21:25 buffer_size_kb
-rw-r----- 1 root tracing 0 May 1 21:25 buffer_subbuf_size_kb
-r--r----- 1 root tracing 0 May 1 21:25 buffer_total_size_kb
-rw-r----- 1 root lkp 0 May 1 21:25 current_tracer
-rw-r----- 1 root tracing 0 May 1 21:25 dynamic_events
-r--r----- 1 root tracing 0 May 1 21:25 dyn_ftrace_total_info
-r--r----- 1 root tracing 0 May 1 21:25 enabled_functions
Everything changed but the "current_tracer".
Add a new link list that keeps track of all the tracefs_inodes which has
the permission flags that tell if the file/dir should use the root inode's
permission or not. Then on remount, clear all the flags so that the
default behavior of using the root inode's permission is done for all
files and directories.

eventfs: Free all of the eventfs_inode after RCU
The freeing of eventfs_inode via a kfree_rcu() callback. But the content
of the eventfs_inode was being freed after the last kref. This is
dangerous, as changes are being made that can access the content of an
eventfs_inode from an RCU loop.
Instead of using kfree_rcu() use call_rcu() that calls a function to do
all the freeing of the eventfs_inode after a RCU grace period has expired.

eventfs/tracing: Add callback for release of an eventfs_inode
Synthetic events create and destroy tracefs files when they are created
and removed. The tracing subsystem has its own file descriptor
representing the state of the events attached to the tracefs files.
There's a race between the eventfs files and this file descriptor of the
tracing system where the following can cause an issue:
With two scripts 'A' and 'B' doing:
Script 'A':
echo "hello int aaa" > /sys/kernel/tracing/synthetic_events
while :
do
echo 0 > /sys/kernel/tracing/events/synthetic/hello/enable
done
Script 'B':
echo > /sys/kernel/tracing/synthetic_events
Script 'A' creates a synthetic event "hello" and then just writes zero
into its enable file.
Script 'B' removes all synthetic events (including the newly created
"hello" event).
What happens is that the opening of the "enable" file has:
{
struct trace_event_file *file = inode->i_private;
int ret;
ret = tracing_check_open_get_tr(file->tr);
[..]
But deleting the events frees the "file" descriptor, and a "use after
free" happens with the dereference at "file->tr".
The file descriptor does have a reference counter, but there needs to be a
way to decrement it from the eventfs when the eventfs_inode is removed
that represents this file descriptor.
Add an optional "release" callback to the eventfs_entry array structure,
that gets called when the eventfs file is about to be removed. This allows
for the creating on the eventfs file to increment the tracing file
descriptor ref counter. When the eventfs file is deleted, it can call the
release function that will call the put function for the tracing file
descriptor.
This will protect the tracing file from being freed while a eventfs file
that references it is being opened.

sound fixes for 6.9-rc7
As usual in a late stage, we received a fair amount of fixes for ASoC, and it became bigger than wished. But all fixes are rather device- specific, and they look pretty safe to apply.

spi: Fixes for v6.9
A few small fixes for v6.9, the core fix is for issues with reuse of a spi_message in the case where we've got queued messages (a relatively rare occurrence with modern code so it wasn't noticed in testing). We also avoid an issue with the Kunpeng driver by simply removing the debug interface that could trigger it, and address issues with confusing and corrupted output when printing the IP version of the AXI SPI engine. -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAmY0RbIACgkQJNaLcl1U h9Ao1wf/dSEewEiXc7VX1vVyF0LnHU71/36b/cJCLFErUNckHvDOa6Be3P0W8ThP WQrbpVizvSCr29hvyNwUtmWLdXFxjyj/69QsXT7NtNCofJTV9kQ5ILgtsj/Pe8Yr aVInONIqyuZlv3xEiRQIt+vnxmz3JM2zVdjFjcj1CrKpEbOob4VGUgwMLi0itvCJ F5WKiVDUMW/LnbEW5mPPyIPbAN1mKGKyGtW4Z9968/BYvUQzz5vzPOst0zvmkHJo SZ47n8G7rbcZXJB4TX62fOTp5gIm+/JQZKQ75MhmxlqYE4/ztZLsvqb9pG86c0+K NqJA/Yjs5rTE5oeIDwBUlSY8Orh0fA== =OIWj -----END PGP SIGNATURE----- Merge tag 'spi-fix-v6.9-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi Pull spi fixes from Mark Brown: "A few small fixes for v6.9, The core fix is for issues with reuse of a spi_message in the case where we've got queued messages (a relatively rare occurrence with modern code so it wasn't noticed in testing).

x86/xen: return a sane initial apic id when running as PV guest
With recent sanity checks for topology information added, there are now
warnings issued for APs when running as a Xen PV guest:
[Firmware Bug]: CPU 1: APIC ID mismatch. CPUID: 0x0000 APIC: 0x0001
This is due to the initial APIC ID obtained via CPUID for PV guests is
always 0.
Avoid the warnings by synthesizing the CPUID data to contain the same
initial APIC ID as xen_pv_smp_config() is using for registering the
APIC IDs of all CPUs.

drm/xe/display: Fix ADL-N detection
Contrary to i915, in xe ADL-N is kept as a different platform, not a subplatform of ADL-P. Since the display side doesn't need to differentiate between P and N, i.e. IS_ALDERLAKE_P_N() is never called, just fixup the compat header to check for both P and N. Moving ADL-N to be a subplatform would be more complex as the firmware loading in xe only handles platforms, not subplatforms, as going forward the direction is to check on IP version rather than platforms/subplatforms. Fix warning when initializing display: xe 0000:00:02.0: [drm:intel_pch_type [xe]] Found Alder Lake PCH ------------[ cut here ]------------ xe 0000:00:02.0: drm_WARN_ON(!((dev_priv)->info.platform == XE_ALDERLAKE_S) && !((dev_priv)->info.platform == XE_ALDERLAKE_P)) And wrong paths being taken on the display side.

The following two driver fixes: * The firewire-ohci driver for 1394 OHCI hardware does not fill time stamp for response packet when handling asynchronous transaction to local destination. This brings an inconvenience that the response packet is not equivalent between the transaction to local and remote. It is fixed by fulfilling the time stamp with hardware time.

x86/xen/smp_pv: Register the boot CPU APIC properly
The topology core expects the boot APIC to be registered from earhy APIC
detection first and then again when the firmware tables are evaluated. This
is used for detecting the real BSP CPU on a kexec kernel.
The recent conversion of XEN/PV to register fake APIC IDs failed to
register the boot CPU APIC correctly as it only registers it once. This
causes the BSP detection mechanism to trigger wrongly:
CPU topo: Boot CPU APIC ID not the first enumerated APIC ID: 0 > 1
Additionally this results in one CPU being ignored.
Register the boot CPU APIC twice so that the XEN/PV fake enumeration
behaves like real firmware.

swiotlb: initialise restricted pool list_head when SWIOTLB_DYNAMIC=y
Using restricted DMA pools (CONFIG_DMA_RESTRICTED_POOL=y) in conjunction

faddr2line reveals that the crash is in the list validation code:

include/linux/rculist.h:79
include/linux/rculist.h:106

because add_mem_pool() is trying to list_add_rcu() to a NULL

Fix the crash by initialising the 'mem->pools' list_head in
rmem_swiotlb_device_init() before calling add_mem_pool().

Merge branch 'net-gro-add-flush-flush_id-checks-and-fix-wrong-offset-in-udp'
Richard Gobert says: ==================== net: gro: add flush/flush_id checks and fix wrong offset in udp This series fixes a bug in the complete phase of UDP in GRO, in which socket lookup fails due to using network_header when parsing encapsulated packets. The fix is to add network_offset and inner_network_offset to napi_gro_cb and use these offsets for socket lookup. In addition p->flush/flush_id should be checked in all UDP flows. The same logic from tcp_gro_receive is applied for all flows in udp_gro_receive_segment. This prevents packets with mismatching network headers (flush/flush_id turned on) from merging in UDP GRO. The original series includes a change to vxlan test which adds the local parameter to prevent similar future bugs. I plan to submit it separately to net-next.

ipv4: Fix uninit-value access in __ip_make_skb()
KMSAN reported uninit-value access in __ip_make_skb() [1]. __ip_make_skb()
tests HDRINCL to know if the skb has icmphdr. However, HDRINCL can cause a
race condition. If calling setsockopt(2) with IP_HDRINCL changes HDRINCL
while __ip_make_skb() is running, the function will access icmphdr in the
skb even if it is not included. This causes the issue reported by KMSAN.
Check FLOWI_FLAG_KNOWN_NH on fl4->flowi4_flags instead of testing HDRINCL
on the socket.
Also, fl4->fl4_icmp_type and fl4->fl4_icmp_code are not initialized. These
are union in struct flowi4 and are implicitly initialized by
flowi4_init_output(), but we should not rely on specific union layout.
Initialize these explicitly in raw_sendmsg().

drm/panel: ili9341: Use predefined error codes
In one case the -1 is returned which is quite confusing code for
the wrong device ID, in another the ret is returning instead of
plain 0 that also confusing as readed may ask the possible meaning
of positive codes, which are never the case there. Convert both
to use explicit predefined error codes to make it clear what's going
on there.

drm/panel: ili9341: Respect deferred probe
GPIO controller might not be available when driver is being probed.
There are plenty of reasons why, one of which is deferred probe.
Since GPIOs are optional, return any error code we got to the upper
layer, including deferred probe. With that in mind, use dev_err_probe()
in order to avoid spamming the logs.

ALSA: hda/realtek: Fix build error without CONFIG_PM
The alc_spec.power_hook is defined only with CONFIG_PM, and the recent
fix overlooked it, resulting in a build error without CONFIG_PM.
Fix it with the simple ifdef and set __maybe_unused for the function.
We may drop the whole CONFIG_PM dependency there, but it should be
done in a separate cleanup patch later.

vxlan: Pull inner IP header in vxlan_rcv().
Ensure the inner IP header is part of skb's linear data before reading its ECN bits. Otherwise we might read garbage. One symptom is the system erroneously logging errors like "vxlan: non-ECT from xxx.xxx.xxx.xxx with TOS=xxxx". Similar bugs have been fixed in geneve, ip_tunnel and ip6_tunnel (see commit |

rxrpc: Clients must accept conn from any address
The find connection logic of Transarc's Rx was modified in the mid-1990s
to support multi-homed servers which might send a response packet from
an address other than the destination address in the received packet.
The rules for accepting a packet by an Rx initiator (RX_CLIENT_CONNECTION)
were altered to permit acceptance of a packet from any address provided
that the port number was unchanged and all of the connection identifiers
matched (Epoch, CID, SecurityClass, ...).
This change applies the same rules to the Linux implementation which makes
it consistent with IBM AFS 3.6, Arla, OpenAFS and AuriStorFS.

drm/xe/vm: prevent UAF in rebind_work_func()
We flush the rebind worker during the vm close phase, however in places like preempt_fence_work_func() we seem to queue the rebind worker without first checking if the vm has already been closed. The concern here is the vm being closed with the worker flushed, but then being rearmed later, which looks like potential uaf, since there is no actual refcounting to track the queued worker. We can't take the vm->lock here in preempt_rebind_work_func() to first check if the vm is closed since that will deadlock, so instead flush the worker again when the vm refcount reaches zero. v2: - Grabbing vm->lock in the preempt worker creates a deadlock, so checking the closed state is tricky. Instead flush the worker when the refcount reaches zero. It should be impossible to queue the preempt worker without already holding vm ref. Fixes: |
