ptrace: Cleanups for v5.18
This set of changes removes tracehook.h, moves modification of all of
the ptrace fields inside of siglock to remove races, adds a missing
permission check to ptrace.c
The removal of tracehook.h is quite significant as it has been a major
source of confusion in recent years. Much of that confusion was
around task_work and TIF_NOTIFY_SIGNAL (which I have now decoupled
making the semantics clearer).
For people who don't know tracehook.h is a vestiage of an attempt to
implement uprobes like functionality that was never fully merged, and
was later superseeded by uprobes when uprobes was merged. For many
years now we have been removing what tracehook functionaly a little
bit at a time. To the point where now anything left in tracehook.h is
some weird strange thing that is difficult to understand.
Eric W. Biederman (15):
ptrace: Move ptrace_report_syscall into ptrace.h
ptrace/arm: Rename tracehook_report_syscall report_syscall
ptrace: Create ptrace_report_syscall_{entry,exit} in ptrace.h
ptrace: Remove arch_syscall_{enter,exit}_tracehook
ptrace: Remove tracehook_signal_handler
task_work: Remove unnecessary include from posix_timers.h
task_work: Introduce task_work_pending
task_work: Call tracehook_notify_signal from get_signal on all architectures
task_work: Decouple TIF_NOTIFY_SIGNAL and task_work
signal: Move set_notify_signal and clear_notify_signal into sched/signal.h
resume_user_mode: Remove #ifdef TIF_NOTIFY_RESUME in set_notify_resume
resume_user_mode: Move to resume_user_mode.h
tracehook: Remove tracehook.h
ptrace: Move setting/clearing ptrace_message into ptrace_stop
ptrace: Return the signal to continue with from ptrace_stop
Jann Horn (1):
ptrace: Check PTRACE_O_SUSPEND_SECCOMP permission on PTRACE_SEIZE
Yang Li (1):

ucounts: Fix shm ucounts
The introduction of a new failure mode when the code was converted to
ucounts resulted in user_shm_lock misbehaving. The change simplifies
the code to make the code easier to follow and remove the known

net/smc: Send out the remaining data in sndbuf before close
The current autocork algorithms will delay the data transmission
in BH context to smc_release_cb() when sock_lock is hold by user.
So there is a possibility that when connection is being actively
closed (sock_lock is hold by user now), some corked data still
remains in sndbuf, waiting to be sent by smc_release_cb(). This
will cause:
- smc_close_stream_wait(), which is called under the sock_lock,
has a high probability of timeout because data transmission is
delayed until sock_lock is released.
- Unexpected data sends may happen after connction closed and use
the rtoken which has been deleted by remote peer through
LLC_DELETE_RKEY messages.
So this patch will try to send out the remaining corked data in
sndbuf before active close process, to ensure data integrity and
avoid unexpected data transmission after close.

net: dsa: bcm_sf2_cfp: fix an incorrect NULL check on list iterator
The bug is here:
return rule;
The list iterator value 'rule' will *always* be set and non-NULL
by list_for_each_entry(), so it is incorrect to assume that the
iterator value will be NULL if the list is empty or no element
is found.
To fix the bug, return 'rule' when found, otherwise return NULL.

net: bnxt_ptp: fix compilation error
The Broadcom bnxt_ptp driver does not compile with GCC 11.2.2 when
CONFIG_WERROR is enabled. The following error is generated:
drivers/net/ethernet/broadcom/bnxt/bnxt_ptp.c: In function ‘bnxt_ptp_enable’:
drivers/net/ethernet/broadcom/bnxt/bnxt_ptp.c:400:43: error: array
subscript 255 is above array bounds of ‘struct pps_pin[4]’
[-Werror=array-bounds]
400 | ptp->pps_info.pins[pin_id].event = BNXT_PPS_EVENT_EXTERNAL;
| ~~~~~~~~~~~~~~~~~~^~~~~~~~
In file included from drivers/net/ethernet/broadcom/bnxt/bnxt_ptp.c:20:
drivers/net/ethernet/broadcom/bnxt/bnxt_ptp.h:75:24: note: while
referencing ‘pins’
75 | struct pps_pin pins[BNXT_MAX_TSIO_PINS];
| ^~~~
cc1: all warnings being treated as errors
This is due to the function ptp_find_pin() returning a pin ID of -1 when
a valid pin is not found and this error never being checked.
Change the TSIO_PIN_VALID() function to also check that a pin ID is not
negative and use this macro in bnxt_ptp_enable() to check the result of
the calls to ptp_find_pin() to return an error early for invalid pins.
This fixes the compilation error.

TTY/Serial driver changes for 5.18-rc1
Here are the big set of tty and serial driver changes for 5.18-rc1.
Nothing major, some more good cleanups from Jiri and 2 new serial
drivers. Highlights include:
- termbits cleanups
- export symbol cleanups and other core cleanups from Jiri Slaby
- new sunplus and mvebu uart drivers (amazing that people are
still creating new uarts...)
- samsung serial driver cleanups
- ldisc 29 is now "reserved" for experimental/development line
disciplines
- lots of other tiny fixes and cleanups to serial drivers and
bindings
All of these have been in linux-next for a while with no reported
issues.

Staging driver update for 5.18-rc1
Here is the big set of staging driver updates for 5.18-rc1.
Loads of tiny cleanups for almost all staging drivers in here, nothing
major at all. Highlights include:
- remove the ashmem Android driver. It is long-dead and if
there are any legacy userspace applications still using it,
the Android kernel images will maintain it, the community
shouldn't care about it anymore
- wfx wifi driver major cleanups. Should be ready to merge out
of staging soon, and will coordinate with the wifi maintainers
after -rc1 is out
- major cleanups and unwinding of the layers of the r8188eu
driver. It's amazing just how many unneeded layers of
abstraction is in there, just when we think it's done, another
is found...
- lots of tiny coding style cleanups in many other staging
drivers.
There will be merge conflict with a fbtft change and the spi driver
changes in your tree, but it's pretty obvious what to do (the function
shouldn't return anything.)
All have been in linux-next for a while with no reported problems.

Driver core changes for 5.18-rc1
Here is the set of driver core changes for 5.18-rc1.
Not much here, primarily it was a bunch of cleanups and small updates:
- kobj_type cleanups for default_groups
- documentation updates
- firmware loader minor changes
- component common helper added and take advantage of it in many
drivers (the largest part of this pull request).
There will be a merge conflict in drivers/power/supply/ab8500_chargalg.c
with your tree, the merge conflict should be easy (take all the
changes).

mm: kfence: fix missing objcg housekeeping for SLAB
The objcg is not cleared and put for kfence object when it is freed,
which could lead to memory leak for struct obj_cgroup and wrong
statistics of NR_SLAB_RECLAIMABLE_B or NR_SLAB_UNRECLAIMABLE_B.
Since the last freed object's objcg is not cleared,
mem_cgroup_from_obj() could return the wrong memcg when this kfence
object, which is not charged to any objcgs, is reallocated to other
users.

32.2.4
Event Trace is a capability that exposes details about the asynchronous
events, when they are generated, and when their corresponding software
event handler completes execution. These include:
o Interrupts, including NMI and SMI, including the interrupt vector when
defined.
o Faults, exceptions including the fault vector.
— Page faults additionally include the page fault address, when in context.
o Event handler returns, including IRET and RSM.
o VM exits and VM entries.¹
— VM exits include the values written to the “exit reason” and “exit qualification” VMCS fields.
INIT and SIPI events.
o TSX aborts, including the abort status returned for the RTM instructions.
o Shutdown.
Additionally, it provides indication of the status of the Interrupt Flag
(IF), to indicate when interrupts are masked.

Add support for Intel CET-IBT, available since Tigerlake (11th gen), which is a
coarse grained, hardware based, forward edge Control-Flow-Integrity mechanism where any indirect CALL/JMP must target an ENDBR instruction or suffer #CP. Additionally, since Alderlake (12th gen)/Sapphire-Rapids, speculation is limited to 2 instructions (and typically fewer) on branch targets not starting with ENDBR. CET-IBT also limits speculation of the next sequential instruction after the indirect CALL/JMP [1]. CET-IBT is fundamentally incompatible with retpolines, but provides, as described above, speculation limits itself.

net/sched: act_ct: fix ref leak when switching zones
When switching zones or network namespaces without doing a ct clear in
between, it is now leaking a reference to the old ct entry. That's
because tcf_ct_skb_nfct_cached() returns false and
tcf_ct_flow_table_lookup() may simply overwrite it.
The fix is to, as the ct entry is not reusable, free it already at
tcf_ct_skb_nfct_cached().

USB/Thunderbolt patches for 5.18-rc1
Here is the big set of USB and Thunderbolt changes for 5.18-rc1.
Nothing major in here, just lots of little improvements and cleanups and
new device support. Highlights are:
- list iterator fixups for when we walk past the end of the list
(a common problem that was cut/pasted in almost all USB gadget
drivers)
- xen USB driver "hardening" for malicious hosts
- xhci driver updates and fixes for more hardware types
- xhci debug cable fixes to make it actually work again
- usb gadget audio driver improvements
- usb gadget storage fixes to work with OS-X
- lots of other small usb gadget fixes and updates
- USB DWC3 driver improvements for more hardware types
- Lots of other small USB driver improvements
- DTS updates for some USB platforms
Note, the DTS updates will have a merge conflict in your tree. The
fixup should be simple, but if not, I can provide a merged tree if
needed.
All of these have been in linux-next for a while with no reported
issues.

No vendor ever really shipped working support for this, and they are not interested in supporting it. With the NVMe support gone, we have nothing in the tree that supports this. Remove passing around of the hints. The only discussion point in this patchset imho is the fact that the file specific write hint setting/getting fcntl helpers will now return -1/EINVAL like they did before we supported write hints. No known applications use these functions, I only know of one prototype that I help do for RocksDB, and that's not used. That said, with a change like this, it's always a bit controversial. Alternatively, we could just make them return 0 and pretend it worked. It's placement based hints after all" * tag 'for-5.18/write-streams-2022-03-18' of git://git.kernel.dk/linux-block: fs: remove fs.f_write_hint fs: remove kiocb.ki_hint block: remove the per-bio/request write hint nvme: remove support or stream based temperature hint |

net: sparx5: switchdev: fix possible NULL pointer dereference
As the possible failure of the allocation, devm_kzalloc() may return NULL
pointer.
Therefore, it should be better to check the 'db' in order to prevent
the dereference of NULL pointer.

net/x25: Fix null-ptr-deref caused by x25_disconnect
When the link layer is terminating, x25->neighbour will be set to NULL
in x25_disconnect(). As a result, it could cause null-ptr-deref bugs in
x25_sendmsg(),x25_recvmsg() and x25_connect(). One of the bugs is
shown below.
(Thread 1) | (Thread 2)
x25_link_terminated() | x25_recvmsg()
x25_kill_by_neigh() | ...
x25_disconnect() | lock_sock(sk)
... | ...
x25->neighbour = NULL //(1) |
... | x25->neighbour->extended //(2)
The code sets NULL to x25->neighbour in position (1) and dereferences
x25->neighbour in position (2), which could cause null-ptr-deref bug.
This patch adds lock_sock() in x25_kill_by_neigh() in order to synchronize
with x25_sendmsg(), x25_recvmsg() and x25_connect(). What`s more, the
sock held by lock_sock() is not NULL, because it is extracted from x25_list
and uses x25_list_lock to synchronize.

qlcnic: dcb: default to returning -EOPNOTSUPP
Clang static analysis reports this issue
qlcnic_dcb.c:382:10: warning: Assigned value is
garbage or undefined
mbx_out = *val;
^ ~~~~
val is set in the qlcnic_dcb_query_hw_capability() wrapper.
If there is no query_hw_capability op in dcp, success is
returned without setting the val.
For this and similar wrappers, return -EOPNOTSUPP.
