lib/lz4: explicitly support in-place decompression
commit 89b158635ad79574bde8e94d45dad33f8cf09549 upstream. LZ4 final literal copy could be overlapped when doing in-place decompression, so it's unsafe to just use memcpy() on an optimized memcpy approach but memmove() instead. Upstream LZ4 has updated this years ago [1] (and the impact is non-sensible [2] plus only a few bytes remain), this commit just synchronizes LZ4 upstream code to the kernel side as well. It can be observed as EROFS in-place decompression failure on specific files when X86_FEATURE_ERMS is unsupported, memcpy() optimization of commit |

kobject_uevent: remove warning in init_uevent_argv()
commit b4104180a2efb85f55e1ba1407885c9421970338 upstream. syzbot can trigger the WARN() in init_uevent_argv() which isn't the nicest as the code does properly recover and handle the error.

kasan: fix unit tests with CONFIG_UBSAN_LOCAL_BOUNDS enabled
commit f649dc0e0d7b509c75570ee403723660f5b72ec7 upstream. These tests deliberately access these arrays out of bounds, which will cause the dynamic local bounds checks inserted by CONFIG_UBSAN_LOCAL_BOUNDS to fail and panic the kernel. To avoid this problem, access the arrays via volatile pointers, which will prevent the compiler from being able to determine the array bounds. These accesses use volatile pointers to char (char *volatile) rather than the more conventional pointers to volatile char (volatile char *) because we want to prevent the compiler from making inferences about the pointer itself (i.e. its array bounds), not the data that it refers to.

crypto: poly1305 - fix poly1305_core_setkey() declaration
[ Upstream commit 8d195e7a8ada68928f2aedb2c18302a4518fe68e ]
gcc-11 points out a mismatch between the declaration and the definition
of poly1305_core_setkey():
lib/crypto/poly1305-donna32.c:13:67: error: argument 2 of type ‘const u8[16]’ {aka ‘const unsigned char[16]’} with mismatched bound [-Werror=array-parameter=]
13 | void poly1305_core_setkey(struct poly1305_core_key *key, const u8 raw_key[16])

In file included from lib/crypto/poly1305-donna32.c:11:

21 | void poly1305_core_setkey(struct poly1305_core_key *key, const u8 *raw_key);
This is harmless in principle, as the calling conventions are the same,
but the more specific prototype allows better type checking in the
caller.
Change the declaration to match the actual function definition.
The poly1305_simd_init() is a bit suspicious here, as it previously
had a 32-byte argument type, but looks like it needs to take the
16-byte POLY1305_BLOCK_SIZE array instead.

In case a PCI host driver's probe is deferred, the same I/O range may be

Fix this by (a) letting logic_pio_register_range() return -EEXIST if the
passed range already exists, so pci_register_io_range() will free it, and
by (b) making pci_register_io_range() not consider -EEXIST an error
condition.

udp: fix skb_copy_and_csum_datagram with odd segment sizes
commit 52cbd23a119c6ebf40a527e53f3402d2ea38eccb upstream.
When iteratively computing a checksum with csum_block_add, track the
offset "pos" to correctly rotate in csum_block_add when offset is odd.
The open coded implementation of skb_copy_and_csum_datagram did this.
With the switch to __skb_datagram_iter calling csum_and_copy_to_iter,
pos was reinitialized to 0 on each call.
Bring back the pos by passing it along with the csum to the callback.
Changes v1->v2
- pass csum value, instead of csump pointer (Alexander Duyck)

This causes build failures on platforms with an old awk, such as macOS and NetBSD.

lib/genalloc: fix the overflow when size is too big
[ Upstream commit 36845663843fc59c5d794e3dc0641472e3e572da ]
Some graphic card has very big memory on chip, such as 32G bytes.
In the following case, it will cause overflow:
pool = gen_pool_create(PAGE_SHIFT, NUMA_NO_NODE);
ret = gen_pool_add(pool, 0x1000000, SZ_32G, NUMA_NO_NODE);
va = gen_pool_alloc(pool, SZ_4G);
The overflow occurs in gen_pool_alloc_algo_owner():
....
size = nbits << order;
....
The @nbits is "int" type, so it will overflow.
Then the gen_pool_avail() will return the wrong value.
This patch converts some "int" to "unsigned long", and
changes the compare code in while.

lib/zlib: fix inflating zlib streams on s390
commit f0bb29e8c4076444d32df00c8d32e169ceecf283 upstream.
Decompressing zlib streams on s390 fails with "incorrect data check"
error.
Userspace zlib checks inflate_state.flags in order to byteswap checksums
only for zlib streams, and s390 hardware inflate code, which was ported
from there, tries to match this behavior. At the same time, kernel zlib
does not use inflate_state.flags, so it contains essentially random
values. For many use cases either zlib stream is zeroed out or checksum
is not used, so this problem is masked, but at least SquashFS is still
affected.
Fix by always passing a checksum to and from the hardware as is, which
matches zlib_inflate()'s expectations.

lib/syscall: fix syscall registers retrieval on 32-bit platforms
Lilith >_> and Claudio Bozzato of Cisco Talos security team reported
that collect_syscall() improperly casts the syscall registers to 64-bit
values leaking the uninitialized last 24 bytes on 32-bit platforms, that
are visible in /proc/self/syscall.
The cause is that info->data.args are u64 while syscall_get_arguments()
uses longs, as hinted by the bogus pointer cast in the function.
Let's just proceed like the other call places, by retrieving the
registers into an array of longs before assigning them to the caller's
array. This was successfully tested on x86_64, i386 and ppc32.

lib/strncpy_from_user.c: Mask out bytes after NUL terminator.
do_strncpy_from_user() may copy some extra bytes after the NUL
terminator into the destination buffer. This usually does not matter for
normal string operations. However, when BPF programs key BPF maps with
strings, this matters a lot.
A BPF program may read strings from user memory by calling the
bpf_probe_read_user_str() helper which eventually calls
do_strncpy_from_user(). The program can then key a map with the
destination buffer. BPF map keys are fixed-width and string-agnostic,
meaning that map keys are treated as a set of bytes.
The issue is when do_strncpy_from_user() overcopies bytes after the NUL
terminator, it can result in seemingly identical strings occupying
multiple slots in a BPF map. This behavior is subtle and totally
unexpected by the user.
This commit masks out the bytes following the NUL while preserving
long-sized stride in the fast path.

kasan: adopt KUNIT tests to SW_TAGS mode
Now that we have KASAN-KUNIT tests integration, it's easy to see that some KASAN tests are not adopted to the SW_TAGS mode and are failing. Adjust the allocation size for kasan_memchr() and kasan_memcmp() by roung it up to OOB_TAG_OFF so the bad access ends up in a separate memory granule. Add a new kmalloc_uaf_16() tests that relies on UAF, and a new kasan_bitops_tags() test that is tailored to tag-based mode, as it's hard to adopt the existing kmalloc_oob_16() and kasan_bitops_generic() (renamed from kasan_bitops()) without losing the precision. Add new kmalloc_uaf_16() and kasan_bitops_uaf() tests that rely on UAFs, as it's hard to adopt the existing kmalloc_oob_16() and kasan_bitops_oob() (rename from kasan_bitops()) without losing the precision. Disable kasan_global_oob() and kasan_alloca_oob_left/right() as SW_TAGS mode doesn't instrument globals nor dynamic allocas.

Driver core / Documentation fixes for 5.10-rc2
Here is one tiny debugfs change to fix up an API where the last user was successfully fixed up in 5.10-rc1 (so it couldn't be merged earlier), and a much larger Documentation/ABI/ update to the files so they can be automatically parsed by our tools. The Documentation/ABI/ updates are just formatting issues, small ones to bring the files into parsable format, and have been acked by numerous subsystem maintainers and the documentation maintainer. I figured it was good to get this into 5.10-rc2 to help with the merge issues that would arise if these were to stick in linux-next until 5.11-rc1. The debugfs change has been in linux-next for a long time, and the Documentation updates only for the last linux-next release.

docs: Kconfig/Makefile: add a check for broken ABI files
The files under Documentation/ABI should follow the syntax as defined at Documentation/ABI/README. Allow checking if they're following the syntax by running the ABI parser script on COMPILE_TEST. With that, when there's a problem with a file under Documentation/ABI, it would produce a warning like: Warning: file ./Documentation/ABI/testing/sysfs-bus-pci-devices-aer_stats#14: What '/sys/bus/pci/devices/<dev>/aer_stats/aer_rootport_total_err_cor' doesn't have a description Warning: file ./Documentation/ABI/testing/sysfs-bus-pci-devices-aer_stats#21: What '/sys/bus/pci/devices/<dev>/aer_stats/aer_rootport_total_err_fatal' doesn't have a description Acked-by: Jonathan Corbet <corbet@lwn.net> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org> Link: https://lore.kernel.org/r/57a38de85cb4b548857207cf1fc1bf1ee08613c9.1604042072.git.mchehab+huawei@kernel.org Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> |

random32: add noise from network and scheduling activity
With the removal of the interrupt perturbations in previous random32
change (random32: make prandom_u32() output unpredictable), the PRNG
has become 100% deterministic again. While SipHash is expected to be
way more robust against brute force than the previous Tausworthe LFSR,
there's still the risk that whoever has even one temporary access to
the PRNG's internal state is able to predict all subsequent draws till
the next reseed (roughly every minute). This may happen through a side
channel attack or any data leak.
This patch restores the spirit of commit

random32: make prandom_u32() output unpredictable
Non-cryptographic PRNGs may have great statistical properties, but are usually trivially predictable to someone who knows the algorithm, given a small sample of their output. An LFSR like prandom_u32() is particularly simple, even if the sample is widely scattered bits. It turns out the network stack uses prandom_u32() for some things like random port numbers which it would prefer are *not* trivially predictable. Predictability led to a practical DNS spoofing attack. Oops. This patch replaces the LFSR with a homebrew cryptographic PRNG based on the SipHash round function, which is in turn seeded with 128 bits of strong random key. (The authors of SipHash have *not* been consulted about this abuse of their algorithm.) Speed is prioritized over security; attacks are rare, while performance is always wanted. Replacing all callers of prandom_u32() is the quick fix. Whether to reinstate a weaker PRNG for uses which can tolerate it is an open question. Commit |

linux-kselftest-kunit-5.10-rc1
This Kunit update for Linux 5.10-rc1 consists of: - add Kunit to kernel_init() and remove KUnit from init calls entirely. This addresses the concern Kunit would not work correctly during late init phase. - add a linker section where KUnit can put references to its test suites. This patch is the first step in transitioning to dispatching all KUnit tests from a centralized executor rather than having each as its own separate late_initcall. - add a centralized executor to dispatch tests rather than relying on late_initcall to schedule each test suite separately. Centralized execution is for built-in tests only; modules will execute tests when loaded. - convert bitfield test to use KUnit framework - Documentation updates for naming guidelines and how kunit_test_suite() works. - add test plan to KUnit TAP format -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEPZKym/RZuOCGeA/kCwJExA0NQxwFAl+Mr68ACgkQCwJExA0N Qxy7HxAAuToPP6uUHwTC3KzVVE4hjP9a3t4hiD7kP/gI0umN+2nrccm6Vx6E+r9t Jkjiv9Yxj3riOkE5jJ8KriAx228mwz3N1yBEDfpp+8iCWOK3iOuFKKTTWOoZY4hf Enlf7n4Yp2TOEmIH0xwh/H67zl0+3FwT3fGWC6DDPXHuw+X+mGphCl9XPB70rZcT q/s0dwx1CmWBm30MgFXN+SZ7CgLP13lRAvkVO4t56/O1SkTbpCe7U1zqT2p5UoOY x7qvzs3pdCaWbpCsAqFWr46iECDHuVQjIgLuddOF/OgWVcCZlv7T7ESd7IDPHUPx DD3zYG0ODV0jKZHmpwkSojSbu3z6v5FnfhLpAcaHoEMBeRu5UIar7EjPHwqrqiU7 JqE7dBECmcD308sr9u0w44DK15nmsD3+njrBQ/AJmsWdg0wtnMvA01nAHKObbk0n 33aIu4Iny1dH35/rt9dV2DKT09f5r0ANCjoJMX8gu/li66FHGfULOaqr6KLLqi5X VPgHCKzyT9nD+Bc2LYzRWmhhAj+5Iwyglgpe9ZiOlPQ5i+hLvfPPAZxVYSbVA1Sk aVZi+ibKUqHSBfXcaLf/OKX7Csf4zni3F+WfFT5ZIC4Y6iEF+0tvS2HW2/pcUAN/ OSPYYmyqhwYIl8tvbQENgBsyU/K1rECxJpqWAznJLRCebkY5a/s= =0Sco -----END PGP SIGNATURE----- Merge tag 'linux-kselftest-kunit-5.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest Pull more Kunit updates from Shuah Khan: - add Kunit to kernel_init() and remove KUnit from init calls entirely.

RDMA 5.10 pull request
The typical set of driver updates across the subsystem:
- Driver minor changes and bug fixes for mlx5, efa, rxe, vmw_pvrdma, hns,
usnic, qib, qedr, cxgb4, hns, bnxt_re
- Various rtrs fixes and updates
- Bug fix for mlx4 CM emulation for virtualization scenarios where MRA
wasn't working right
- Use tracepoints instead of pr_debug in the CM code
- Scrub the locking in ucma and cma to close more syzkaller bugs
- Use tasklet_setup in the subsystem
- Revert the idea that 'destroy' operations are not allowed to fail at
the driver level. This proved unworkable from a HW perspective.
- Revise how the umem API works so drivers make fewer mistakes using it
- XRC support for qedr
- Convert uverbs objects RWQ and MW to new the allocation scheme
- Large queue entry sizes for hns
- Use hmm_range_fault() for mlx5 On Demand Paging

kgdb patches for 5.10-rc1
A fairly modest set of changes for this cycle. Of particular note are an earlycon fix from Doug Anderson and my own changes to get kgdb/kdb to honour the kprobe blocklist. The later creates a safety rail that strongly encourages developers not to place breakpoints in, for example, arch specific trap handling code. Also included are a couple of small fixes and tweaks: an API update, eliminate a coverity dead code warning, improved handling of search during multi-line printk and a couple of typo corrections.
