dump_stack: avoid the livelock of the dump_lock
In the current code, we use the atomic_cmpxchg() to serialize the output
of the dump_stack(), but this implementation suffers the thundering herd
problem. We have observed such kind of livelock on a Marvell cn96xx
board(24 cpus) when heavily using the dump_stack() in a kprobe handler.
Actually we can let the competitors to wait for the releasing of the
lock before jumping to atomic_cmpxchg(). This will definitely mitigate
the thundering herd problem. Thanks Linus for the suggestion.

idr: Fix idr_alloc_u32 on 32-bit systems
Attempting to allocate an entry at 0xffffffff when one is already present would succeed in allocating one at 2^32, which would confuse everything. Return -ENOSPC in this case, as expected. Signed-off-by: Matthew Wilcox (Oracle) <willy@infradead.org> |

lib/vdso: Make clock_getres() POSIX compliant again
A recent commit removed the NULL pointer check from the clock_getres()
implementation causing a test case to fault.
POSIX requires an explicit NULL pointer check for clock_getres() aside of
the validity check of the clock_id argument for obscure reasons.
Add it back for both 32bit and 64bit.
Note, this is only a partial revert of the offending commit which does not
bring back the broken fallback invocation in the the 32bit compat
implementations of clock_getres() and clock_gettime().

But it's freed later. Kmemleak misses the allocation because its
pointer is stored in the generic radix tree sctp_stream::out, and the
generic radix tree uses raw pages which aren't tracked by kmemleak.
Fix this by adding the kmemleak hooks to the generic radix tree code.

The bulk of the fixes are dealing with a bunch of issues with the build system from the compat vDSO, which unfortunately led to some significant Makefile rework to manage the horrible combinations of toolchains that we can end up needing to drive simultaneously. We came close to disabling the thing entirely, but Vincenzo was quick to spin up some patches and I ended up picking up most of the bits that were left [*]. Future work will look at disentangling the header files properly. Other than that, we have some important fixes all over, including one papering over the miscompilation fallout from forcing CONFIG_OPTIMIZE_INLINING=y, which I'm still unhappy about. Harumph.

lib: Ignore kasan errors from find_next_bit and last bit
find_next_bit and find_last_bit code operates on the unsigned long *addr, and without knowing the size of the actual buffer passed to it, Kasan detects it as invalid Out of Bound read access. find_next_bit and find_last_bit implementation is very generic and it need not to be modified for the Kasan, so we are skipping it from the sanitization.

lib/string: Make memzero_explicit() inline instead of external
With the use of the barrier implied by barrier_data(), there is no need
for memzero_explicit() to be extern. Making it inline saves the overhead
of a function call, and allows the code to be reused in arch/*/purgatory
without having to duplicate the implementation.

lib: test_user_copy: style cleanup
While writing the tests for copy_struct_from_user(), I used a construct that Linus doesn't appear to be too fond of: On 2019-10-04, Linus Torvalds <torvalds@linux-foundation.org> wrote: > Hmm.

lib: introduce copy_struct_from_user() helper
A common pattern for syscall extensions is increasing the size of a
struct passed from userspace, such that the zero-value of the new fields
result in the old kernel behaviour (allowing for a mix of userspace and
kernel vintages to operate on one another in most cases).
While this interface exists for communication in both directions, only
one interface is straightforward to have reasonable semantics for
(userspace passing a struct to the kernel). For kernel returns to
userspace, what the correct semantics are (whether there should be an
error if userspace is unaware of a new extension) is very
syscall-dependent and thus probably cannot be unified between syscalls
(a good example of this problem is [1]).
Previously there was no common lib/ function that implemented
the necessary extension-checking semantics (and different syscalls
implemented them slightly differently or incompletely[2]). Future
patches replace common uses of this pattern to make use of
copy_struct_from_user().
Some in-kernel selftests that insure that the handling of alignment and
various byte patterns are all handled identically to memchr_inv() usage.

lib: untag user pointers in strn*_user
Patch series "arm64: untag user pointers passed to the kernel", v19. === Overview arm64 has a feature called Top Byte Ignore, which allows to embed pointer tags into the top byte of each pointer. Userspace programs (such as HWASan, a memory debugging tool [1]) might use this feature and pass tagged user pointers to the kernel through syscalls or other interfaces. Right now the kernel is already able to handle user faults with tagged pointers, due to these patches: 1. |

bug: move WARN_ON() "cut here" into exception handler
The original clean up of "cut here" missed the WARN_ON() case (that does
not have a printk message), which was fixed recently by adding an explicit
printk of "cut here". This had the downside of adding a printk() to every
WARN_ON() caller, which reduces the utility of using an instruction
exception to streamline the resulting code. By making this a new BUGFLAG,
all of these can be removed and "cut here" can be handled by the exception
handler.
This was very pronounced on PowerPC, but the effect can be seen on x86 as
well. The resulting text size of a defconfig build shows some small
savings from this patch:
text data bss dec hex filename
19691167 5134320 1646664 26472151 193eed7 vmlinux.before
19676362 5134260 1663048 26473670 193f4c6 vmlinux.after
This change also opens the door for creating something like BUG_MSG(),
where a custom printk() before issuing BUG(), without confusing the "cut
here" line.

lib/hexdump: make print_hex_dump_bytes() a nop on !DEBUG builds
I'm seeing a bunch of debug prints from a user of print_hex_dump_bytes() in my kernel logs, but I don't have CONFIG_DYNAMIC_DEBUG enabled nor do I have DEBUG defined in my build. The problem is that print_hex_dump_bytes() calls a wrapper function in lib/hexdump.c that calls print_hex_dump() with KERN_DEBUG level. There are three cases to consider here 1. CONFIG_DYNAMIC_DEBUG=y --> call dynamic_hex_dum() 2. CONFIG_DYNAMIC_DEBUG=n && DEBUG --> call print_hex_dump() 3. CONFIG_DYNAMIC_DEBUG=n && !DEBUG --> stub it out Right now, that last case isn't detected and we still call print_hex_dump() from the stub wrapper. Let's make print_hex_dump_bytes() only call print_hex_dump_debug() so that it works properly in all cases. Case #1, print_hex_dump_debug() calls dynamic_hex_dump() and we get same behavior. Case #2, print_hex_dump_debug() calls print_hex_dump() with KERN_DEBUG and we get the same behavior. Case #3, print_hex_dump_debug() is a nop, changing behavior to what we want, i.e. print nothing.

mm: remove quicklist page table caches
Patch series "mm: remove quicklist page table caches". A while ago Nicholas proposed to remove quicklist page table caches [1]. I've rebased his patch on the curren upstream and switched ia64 and sh to use generic versions of PTE allocation. [1] https://lore.kernel.org/linux-mm/20190711030339.20892-1-npiggin@gmail.com This patch (of 3): Remove page table allocator "quicklists". These have been around for a long time, but have not got much traction in the last decade and are only used on ia64 and sh architectures. The numbers in the initial commit look interesting but probably don't apply anymore. If anybody wants to resurrect this it's in the git history, but it's unhelpful to have this code and divergent allocator behaviour for minor archs. Also it might be better to instead make more general improvements to page allocator if this is still so slow.

In several places we need to be able to operate on pointers which have
gone via a roundtrip:
virt -> {phys,page} -> virt
With KASAN_SW_TAGS, we can't preserve the tag for SLUB objects, and the
{phys,page} -> virt conversion will use KASAN_TAG_KERNEL.
This patch adds tests to ensure that this works as expected, without
false positives which have recently been spotted [1,2] in testing.
