Pull vdso timer fixes from Thomas Gleixner: "A series of commits to deal with the regression caused by the generic VDSO implementation. The usage of clock_gettime64() for 32bit compat fallback syscalls caused seccomp filters to kill innocent processes because they only allow clock_gettime(). Handle the compat syscalls with clock_gettime() as before, which is not a functional problem for the VDSO as the legacy compat application interface is not y2038 safe anyway. It's just extra fallback code which needs to be implemented on every architecture. It's opt in for now so that it does not break the compile of already converted architectures in linux-next. Once these are fixed, the #ifdeffery goes away. So much for trying to be smart and reuse code..." * 'timers-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: arm64: compat: vdso: Use legacy syscalls as fallback x86/vdso/32: Use 32bit syscall fallback lib/vdso/32: Provide legacy syscall fallbacks lib/vdso: Move fallback invocation to the callers lib/vdso/32: Remove inconsistent NULL pointer checks |

ubsan: build ubsan.c more conservatively
objtool points out several conditions that it does not like, depending
on the combination with other configuration options and compiler
variants:
stack protector:
lib/ubsan.o: warning: objtool: __ubsan_handle_type_mismatch()+0xbf: call to __stack_chk_fail() with UACCESS enabled
lib/ubsan.o: warning: objtool: __ubsan_handle_type_mismatch_v1()+0xbe: call to __stack_chk_fail() with UACCESS enabled

lib/ubsan.o: warning: objtool: __ubsan_handle_type_mismatch_v1()+0x4a: call to stackleak_track_stack() with UACCESS enabled

lib/ubsan.o: warning: objtool: __ubsan_handle_type_mismatch_v1()+0x25: call to memcpy() with UACCESS enabled
The stackleak and kasan options just need to be disabled for this file
as we do for other files already. For the stack protector, we already
attempt to disable it, but this fails on clang because the check is
mixed with the gcc specific -fno-conserve-stack option. According to
Andrey Ryabinin, that option is not even needed, dropping it here fixes
the stackprotector issue.

kasan: remove clang version check for KASAN_STACK
asan-stack mode still uses dangerously large kernel stacks of tens of
kilobytes in some drivers, and it does not seem that anyone is working
on the clang bug.
Turn it off for all clang versions to prevent users from accidentally
enabling it once they update to clang-9, and to help automated build
testing with clang-9.

lib/vdso/32: Provide legacy syscall fallbacks
To address the regression which causes seccomp to deny applications the
access to clock_gettime64() and clock_getres64() syscalls because they
are not enabled in the existing filters.
That trips over the fact that 32bit VDSOs use the new clock_gettime64() and
clock_getres64() syscalls in the fallback path.
Add a conditional to invoke the 32bit legacy fallback syscalls instead of
the new 64bit variants. The conditional can go away once all architectures
are converted.

lib/vdso: Move fallback invocation to the callers
To allow syscall fallbacks using the legacy 32bit syscall for 32bit VDSO
builds, move the fallback invocation out into the callers.
Split the common code out of __cvdso_clock_gettime/getres() and invoke the
syscall fallback in the 64bit and 32bit variants.
Preparatory work for using legacy syscalls in 32bit VDSO. No functional
change.

lib/vdso/32: Remove inconsistent NULL pointer checks
The 32bit variants of vdso_clock_gettime()/getres() have a NULL pointer
check for the timespec pointer. That's inconsistent vs. 64bit.
But the vdso implementation will never be consistent versus the syscall
because the only case which it can handle is NULL. Any other invalid
pointer will cause a segfault. So special casing NULL is not really useful.
Remove it along with the superflouos syscall fallback invocation as that
will return -EFAULT anyway. That also gets rid of the dubious typecast
which only works because the pointer is NULL.

test_firmware: fix a memory leak bug
In test_firmware_init(), the buffer pointed to by the global pointer 'test_fw_config' is allocated through kzalloc(). Then, the buffer is initialized in __test_firmware_config_init(). In the case that the initialization fails, the following execution in test_firmware_init() needs to be terminated with an error code returned to indicate this failure. However, the allocated buffer is not freed on this execution path, leading to a memory leak bug. To fix the above issue, free the allocated buffer before returning from test_firmware_init().

kbuild: create *.mod with full directory path and remove MODVERDIR
While descending directories, Kbuild produces objects for modules, but do not link final *.ko files; it is done in the modpost. To keep track of modules, Kbuild creates a *.mod file in $(MODVERDIR) for every module it is building. Some post-processing steps read the necessary information from *.mod files. This avoids descending into directories again. This mechanism was introduced in 2003 or so. Later, commit |

lib/rbtree: avoid generating code twice for the cached versions
As was already noted in rbtree.h, the logic to cache rb_first (or rb_last) can easily be implemented externally to the core rbtree api. Change the implementation to do just that. Previously the update of rb_leftmost was wired deeper into the implmentation, but there were some disadvantages to that - mostly, lib/rbtree.c had separate instantiations for rb_insert_color() vs rb_insert_color_cached(), as well as rb_erase() vs rb_erase_cached(), which were doing exactly the same thing save for the rb_leftmost update at the start of either function. text data bss dec hex filename 5405 120 0 5525 1595 lib/rbtree.o-vanilla 3827 96 0 3923 f53 lib/rbtree.o-patch [dave@stgolabs.net: changelog addition] Link: http://lkml.kernel.org/r/20190628171416.by5gdizl3rcxk5h5@linux-r8p5 [akpm@linux-foundation.org: coding-style fixes] Link: http://lkml.kernel.org/r/20190628045008.39926-1-walken@google.com Signed-off-by: Michel Lespinasse <walken@google.com> Acked-by: Davidlohr Bueso <dbueso@suse.de> Acked-by: Peter Zijlstra (Intel) <peterz@infradead.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |

mm/ioremap: check virtual address alignment while creating huge mappings
Virtual address alignment is essential in ensuring correct clearing for all intermediate level pgtable entries and freeing associated pgtable pages. An unaligned address can end up randomly freeing pgtable page that potentially still contains valid mappings. Hence also check it's alignment along with existing phys_addr check.

lib/test_string.c: avoid masking memset16/32/64 failures
If a memsetXX implementation is completely broken and fails in the first
iteration, when i, j, and k are all zero, the failure is masked as zero
is returned. Failing in the first iteration is perhaps the most likely
failure, so this makes the tests pretty much useless. Avoid the
situation by always setting a random unused bit in the result on
failure.

lib/string.c: allow searching for NUL with strnchr
Patch series "lib/string: search for NUL with strchr/strnchr". I noticed an inconsistency where strchr and strnchr do not behave the same with respect to the trailing NUL. strchr is standardised and the kernel function conforms, and the kernel relies on the behavior. So, naturally strchr stays as-is and strnchr is what I change. While writing a few tests to verify that my new strnchr loop was sane, I noticed that the tests for memset16/32/64 had a problem. Since it's all about the lib/string.c file I made a short series of it all... This patch (of 3): strchr considers the terminating NUL to be part of the string, and NUL can thus be searched for with that function. For consistency, do the same with strnchr.

lib/mpi/longlong.h: fix building with 32-bit x86
The mpi library contains some rather old inline assembly statements that
produce a lot of warnings for 32-bit x86, such as:
lib/mpi/mpih-div.c:76:16: error: invalid use of a cast in a inline asm context requiring an l-value: remove the cast or build with -fheinous-gnu-extensions
udiv_qrnnd(qp[i], n1, n1, np[i], d);
~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~
lib/mpi/longlong.h:423:20: note: expanded from macro 'udiv_qrnnd'
: "=a" ((USItype)(q)), \
~~~~~~~~~~^~
There is no point in doing a type cast for the output of an inline
assembler statement, so just remove the cast here, as we have done for
other architectures in the past.

Convert the locking documents to ReST and add them to the kernel development book where it belongs. Most of the stuff here is just to make Sphinx to properly parse the text file, as they're already in good shape, not requiring massive changes in order to be parsed. The conversion is actually: - add blank lines and identation in order to identify paragraphs; - fix tables markups; - add some lists markups; - mark literal blocks; - adjust title markups. At its new index.rst, let's add a :orphan: while this is not linked to the main index.rst file, in order to avoid build warnings.

Driver Core and debugfs changes for 5.3-rc1
Here is the "big" driver core and debugfs changes for 5.3-rc1 It's a lot of different patches, all across the tree due to some api changes and lots of debugfs cleanups. Because of this, there is going to be some merge issues with your tree at the moment, I'll follow up with the expected resolutions to make it easier for you. Other than the debugfs cleanups, in this set of changes we have: - bus iteration function cleanups (will cause build warnings with s390 and coresight drivers in your tree) - scripts/get_abi.pl tool to display and parse Documentation/ABI entries in a simple way - cleanups to Documenatation/ABI/ entries to make them parse easier due to typos and other minor things - default_attrs use for some ktype users - driver model documentation file conversions to .rst - compressed firmware file loading - deferred probe fixes All of these have been in linux-next for a while, with a bunch of merge issues that Stephen has been patient with me for.

Char / Misc driver patches for 5.3-rc1
Here is the "large" pull request for char and misc and other assorted smaller driver subsystems for 5.3-rc1. It seems that this tree is becoming the funnel point of lots of smaller driver subsystems, which is fine for me, but that's why it is getting larger over time and does not just contain stuff under drivers/char/ and drivers/misc. Lots of small updates all over the place here from different driver subsystems: - habana driver updates - coresight driver updates - documentation file movements and updates - Android binder fixes and updates - extcon driver updates - google firmware driver updates - fsi driver updates - smaller misc and char driver updates - soundwire driver updates - nvmem driver updates - w1 driver fixes All of these have been in linux-next for a while with no reported issues.

SCSI sg on 20190709
This topic branch covers a fundamental change in how our sg lists are allocated to make mq more efficient by reducing the size of the preallocated sg list. This necessitates a large number of driver changes because the previous guarantee that if a driver specified SG_ALL as the size of its scatter list, it would get a non-chained list and didn't need to bother with scatterlist iterators is now broken and every driver *must* use scatterlist iterators. This was broken out as a separate topic because we need to convert all the drivers before pulling the trigger and unconverted drivers kept being found, necessitating a rebase.

Highlights:
- Add a new /proc/fs/nfsd/clients/ directory which exposes some long-requested information about NFSv4 clients (like open files) and allows forced revocation of client state. - Replace the global duplicate reply cache by a cache per network namespace; previously, a request in one network namespace could incorrectly match an entry from another, though we haven't seen this in production. This is the last remaining container bug that I'm aware of; at this point you should be able to run separate nfsd's in each network namespace, each with their own set of exports, and everything should work. - Cleanup and modify lock code to show the pid of lockd as the owner of NLM locks. This is the correct version of the bugfix originally attempted in |

Examples include splitting the revocation permit from the change-attributes permit, thereby allowing someone to be granted permission to revoke a key without allowing them to change the owner; also the ability to join a keyring is split from the ability to link to it, thereby stopping a process accessing a keyring by joining it and thus acquiring use of possessor permits. - Provide a keyctl to allow the granting or denial of one or more permits to a specific subject.
