TTY/Serial driver updates for 5.17-rc1
Here is the big set of tty/serial driver updates for 5.17-rc1.
Nothing major in here, just lots of good updates and fixes, including:
- more tty core cleanups from Jiri as well as mxser driver
cleanups. This is the majority of the core diffstat
- tty documentation updates from Jiri
- platform_get_irq() updates
- various serial driver updates for new features and hardware
- fifo usage for 8250 console, reducing cpu load a lot
- LED fix for keyboards, long-time bugfix that went through many
revisions
- minor cleanups
All have been in linux-next for a while with no reported problems.

locking: Allow to include asm/spinlock_types.h from linux/spinlock_types_raw.h
The printk header file includes ratelimit_types.h for its __ratelimit() based usage. It is required for the static initializer used in printk_ratelimited(). It uses a raw_spinlock_t and includes the spinlock_types.h. PREEMPT_RT substitutes spinlock_t with a rtmutex based implementation and so its spinlock_t implmentation (provided by spinlock_rt.h) includes rtmutex.h and atomic.h which leads to recursive includes where defines are missing. By including only the raw_spinlock_t defines it avoids the atomic.h related includes at this stage. An example on powerpc: | CALL scripts/atomic/check-atomics.sh |In file included from include/linux/bug.h:5, | from include/linux/page-flags.h:10, | from kernel/bounds.c:10: |arch/powerpc/include/asm/page_32.h: In function âclear_pageâ: |arch/powerpc/include/asm/bug.h:87:4: error: implicit declaration of function â=80=98__WARNâ=80=99 [-Werror=3Dimplicit-function-declaration] | 87 | __WARN(); \ | | ^~~~~~ |arch/powerpc/include/asm/page_32.h:48:2: note: in expansion of macro âWARN_ONâ=99 | 48 | WARN_ON((unsigned long)addr & (L1_CACHE_BYTES - 1)); | | ^~~~~~~ |arch/powerpc/include/asm/bug.h:58:17: error: invalid application of âsizeofâ=99 to incomplete type âstruct bug_entryâ=99 | 58 | "i" (sizeof(struct bug_entry)), \ | | ^~~~~~ |arch/powerpc/include/asm/bug.h:89:3: note: in expansion of macro âBUG_ENTRYâ=99 | 89 | BUG_ENTRY(PPC_TLNEI " %4, 0", \ | | ^~~~~~~~~ |arch/powerpc/include/asm/page_32.h:48:2: note: in expansion of macro âWARN_ONâ=99 | 48 | WARN_ON((unsigned long)addr & (L1_CACHE_BYTES - 1)); | | ^~~~~~~ |In file included from arch/powerpc/include/asm/ptrace.h:298, | from arch/powerpc/include/asm/hw_irq.h:12, | from arch/powerpc/include/asm/irqflags.h:12, | from include/linux/irqflags.h:16, | from include/asm-generic/cmpxchg-local.h:6, | from arch/powerpc/include/asm/cmpxchg.h:526, | from arch/powerpc/include/asm/atomic.h:11, | from include/linux/atomic.h:7, | from include/linux/rwbase_rt.h:6, | from include/linux/rwlock_types.h:55, | from include/linux/spinlock_types.h:74, | from include/linux/ratelimit_types.h:7, | from include/linux/printk.h:10, | from include/asm-generic/bug.h:22, | from arch/powerpc/include/asm/bug.h:109, | from include/linux/bug.h:5, | from include/linux/page-flags.h:10, | from kernel/bounds.c:10: |include/linux/thread_info.h: In function â=80=98copy_overflowâ=80=99: |include/linux/thread_info.h:210:2: error: implicit declaration of function â=80=98WARNâ=80=99 [-Werror=3Dimplicit-function-declaration] | 210 | WARN(1, "Buffer overflow detected (%d < %lu)!\n", size, count); | | ^~~~ The WARN / BUG include pulls in printk.h and then ptrace.h expects WARN (from bug.h) which is not yet complete.

alpha: Snapshot thread flags
Some thread flags can be set remotely, and so even when IRQs are disabled, the flags can change under our feet. Generally this is unlikely to cause a problem in practice, but it is somewhat unsound, and KCSAN will legitimately warn that there is a data race. To avoid such issues, a snapshot of the flags has to be taken prior to using them. Some places already use READ_ONCE() for that, others do not. Convert them all to the new flag accessor helpers.

memblock: use memblock_free for freeing virtual pointers
Rename memblock_free_ptr() to memblock_free() and use memblock_free()
when freeing a virtual pointer so that memblock_free() will be a
counterpart of memblock_alloc()
The callers are updated with the below semantic patch and manual
addition of (void *) casting to pointers that are represented by
unsigned long variables.

memblock: rename memblock_free to memblock_phys_free
Since memblock_free() operates on a physical range, make its name

alpha: move __udiv_qrnnd library function to arch/alpha/lib/
We already had the implementation for __udiv_qrnnd (unsigned divide for multi-precision arithmetic) as part of the alpha math emulation code. But you can disable the math emulation code - even if you shouldn't - and then the MPI code that actually wants this functionality (and is needed by various crypto functions) will fail to build. So move the extended-precision divide code to be a regular library function, just like all the regular division code is. That way ie is available regardless of math-emulation.

alpha: mark 'Jensen' platform as no longer broken
Ok, it almost certainly is still broken on actual hardware, but the
immediate reason for it having been marked BROKEN was a build error that
is fixed by just making sure the low-level IO header file is included
sufficiently early that the __EXTERN_INLINE hackery takes effect.
This was marked broken back in 2017 by commit

alpha: make 'Jensen' IO functions build again
The Jensen IO functions are overly copmplicated because some of the IO addresses refer to special 'local IO' ports, and they get accessed differently. That then makes gcc not actually inline them, and since they were marked "extern inline" when included through the regular <asm/io.h> path, and then only marked "inline" when included from sys_jensen.c, you never necessarily got a body for the IO functions at all. The intent of the sys_jensen.c code is to actually get the non-inlined copy generated, so remove the 'inline' from the magic macro that is supposed to sort this all out. Also, do not mix 'extern inline' functions (that may or may not be inlined and will not generate a function body if they are not) with 'static inline' (that _will_ generate a function body when not inlined). Because gcc will complain about this situation: error: ‘jensen_bus_outb’ is static but used in inline function ‘jensen_outb’ which is not static because gcc basically doesn't know whether to generate a body for that static inline function or not for that call site. So make all of these use that __EXTERN_INLINE marker. Gcc will generally not inline these things on use, and then generate the function body out-of-line in sys_jensen.c. This makes the core IO functions build for the alpha Jensen config. Not that the rest then builds, because it turns out Jensen also doesn't enable PCI, which then makes other drievrs very unhappy, but that's a separate issue.

alpha: Move setup.h out of uapi
Most of the contents of setup.h have no value for userspace applications. The file was probably moved to uapi accidentally. Keep the file in uapi to define the alpha-specific COMMAND_LINE_SIZE. Move all other defines to arch/alpha/include/asm/setup.h.

asm-generic changes for 5.15
The main content for 5.15 is a series that cleans up the handling of
strncpy_from_user() and strnlen_user(), removing a lot of slightly
incorrect versions of these in favor of the lib/strn*.c helpers
that implement these correctly and more efficiently.
The only architectures that retain a private version now are
mips, ia64, um and parisc. I had offered to convert those at all,
but Thomas Bogendoerfer wanted to keep the mips version for the
moment until he had a chance to do regression testing.
The branch also contains two patches for bitops and for ffs().

Most of that code I did not manage to get tested and reviewed before the merge window opened but a handful of very useful cleanups are ready to be merged. The first change is simply the removal of the bdflush system call. The code has now been disabled long enough that even the oldest userspace working userspace setups anyone can find to test are fine with the bdflush system call being removed. Changing m68k fsp040_die to use force_sigsegv(SIGSEGV) instead of calling do_exit directly is interesting only in that it is nearly the most difficult of the incorrect uses of do_exit to remove. The change to the seccomp code to simply send a signal instead of calling do_coredump directly is a very nice little cleanup made possible by realizing the existing signal sending helpers were missing a little bit of functionality that is easy to provide" * 'exit-cleanups-for-v5.15' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: signal/seccomp: Dump core when there is only one live thread signal/seccomp: Refactor seccomp signal and coredump generation signal/m68k: Use force_sigsegv(SIGSEGV) in fpsp040_die exit/bdflush: Remove the deprecated bdflush system call |

sock: allow reading and changing sk_userlocks with setsockopt
SOCK_SNDBUF_LOCK and SOCK_RCVBUF_LOCK flags disable automatic socket
buffers adjustment done by kernel (see tcp_fixup_rcvbuf() and
tcp_sndbuf_expand()). If we've just created a new socket this adjustment
is enabled on it, but if one changes the socket buffer size by
setsockopt(SO_{SND,RCV}BUF*) it becomes disabled.
CRIU needs to call setsockopt(SO_{SND,RCV}BUF*) on each socket on
restore as it first needs to increase buffer sizes for packet queues
restore and second it needs to restore back original buffer sizes. So
after CRIU restore all sockets become non-auto-adjustable, which can
decrease network performance of restored applications significantly.
CRIU need to be able to restore sockets with enabled/disabled adjustment
to the same state it was before dump, so let's add special setsockopt
for it.
Let's also export SOCK_SNDBUF_LOCK and SOCK_RCVBUF_LOCK flags to uAPI so
that using these interface one can reenable automatic socket buffer
adjustment on their sockets.

asm-generic: reverse GENERIC_{STRNCPY_FROM,STRNLEN}_USER symbols
Most architectures do not need a custom implementation, and in most
cases the generic implementation is preferred, so change the polariy
on these Kconfig symbols to require architectures to select them when
they provide their own version.
The new name is CONFIG_ARCH_HAS_{STRNCPY_FROM,STRNLEN}_USER.
The remaining architectures at the moment are: ia64, mips, parisc,
um and xtensa. We should probably convert these as well, but
I was not sure how far to take this series. Thomas Bogendoerfer
had some concerns about converting mips but may still do some
more detailed measurements to see which version is better.

tty: drop put_tty_driver
put_tty_driver() is an alias for tty_driver_kref_put(). There is no need for two exported identical functions, therefore switch all users of old put_tty_driver() to new tty_driver_kref_put() and remove the former for good.
