libfs: fix error cast of negative value in simple_attr_write()
The attr->set() receive a value of u64, but simple_strtoll() is used for
doing the conversion. It will lead to the error cast if user inputs a
negative value.
Use kstrtoull() instead of simple_strtoll() to convert a string got from
the user to an unsigned value. The former will return '-EINVAL' if it
gets a negetive value, but the latter can't handle the situation
correctly. Make 'val' unsigned long long as what kstrtoull() takes,
this will eliminate the compile warning on no 64-bit architectures.

mm/userfaultfd: do not access vma->vm_mm after calling handle_userfault()
Alexander reported a syzkaller / KASAN finding on s390, see below for complete output. In do_huge_pmd_anonymous_page(), the pre-allocated pagetable will be freed in some cases. In the case of userfaultfd_missing(), this will happen after calling handle_userfault(), which might have released the mmap_lock. Therefore, the following pte_free(vma->vm_mm, pgtable) will access an unstable vma->vm_mm, which could have been freed or re-used already. For all architectures other than s390 this will go w/o any negative impact, because pte_free() simply frees the page and ignores the passed-in mm. The implementation for SPARC32 would also access mm->page_table_lock for pte_free(), but there is no THP support in SPARC32, so the buggy code path will not be used there. For s390, the mm->context.pgtable_list is being used to maintain the 2K pagetable fragments, and operating on an already freed or even re-used mm could result in various more or less subtle bugs due to list / pagetable corruption. Fix this by calling pte_free() before handle_userfault(), similar to how it is already done in __do_huge_pmd_anonymous_page() for the WRITE / non-huge_zero_page case. Commit |

mm: memcg/slab: fix root memcg vmstats
If we reparent the slab objects to the root memcg, when we free the slab
object, we need to update the per-memcg vmstats to keep it correct for
the root memcg. Now this at least affects the vmstat of
NR_KERNEL_STACK_KB for !CONFIG_VMAP_STACK when the thread stack size is
smaller than the PAGE_SIZE.
David said:
"I assume that without this fix that the root memcg's vmstat would
always be inflated if we reparented"

mm: fix readahead_page_batch for retry entries
Both btrfs and fuse have reported faults caused by seeing a retry entry
instead of the page they were looking for. This was caused by a missing
check in the iterator.
As can be seen in the below panic log, the accessing 0x402 causes a
panic. In the xarray.h, 0x402 means RETRY_ENTRY.

mm: fix phys_to_target_node() and memory_add_physaddr_to_nid() exports
The core-mm has a default __weak implementation of phys_to_target_node()
to mirror the weak definition of memory_add_physaddr_to_nid(). That
symbol is exported for modules. However, while the export in
mm/memory_hotplug.c exported the symbol in the configuration cases of:
CONFIG_NUMA_KEEP_MEMINFO=y
CONFIG_MEMORY_HOTPLUG=y
...and:
CONFIG_NUMA_KEEP_MEMINFO=n
CONFIG_MEMORY_HOTPLUG=y
...it failed to export the symbol in the case of:
CONFIG_NUMA_KEEP_MEMINFO=y
CONFIG_MEMORY_HOTPLUG=n
Not only is that broken, but Christoph points out that the kernel should
not be exporting any __weak symbol, which means that
memory_add_physaddr_to_nid() example that phys_to_target_node() copied
is broken too.
Rework the definition of phys_to_target_node() and
memory_add_physaddr_to_nid() to not require weak symbols. Move to the
common arch override design-pattern of an asm header defining a symbol
to replace the default implementation.
The only common header that all memory_add_physaddr_to_nid() producing
architectures implement is asm/sparsemem.h. In fact, powerpc already
defines its memory_add_physaddr_to_nid() helper in sparsemem.h.
Double-down on that observation and define phys_to_target_node() where
necessary in asm/sparsemem.h. An alternate consideration that was
discarded was to put this override in asm/numa.h, but that entangles
with the definition of MAX_NUMNODES relative to the inclusion of
linux/nodemask.h, and requires powerpc to grow a new header.
The dependency on NUMA_KEEP_MEMINFO for DEV_DAX_HMEM_DEVICES is invalid
now that the symbol is properly exported / stubbed in all combinations
of CONFIG_NUMA_KEEP_MEMINFO and CONFIG_MEMORY_HOTPLUG.

compiler-clang: remove version check for BPF Tracing

Networking fixes for 5.10-rc5, including fixes from the WiFi (mac80211),
can and bpf (including the strncpy_from_user fix).
Current release - regressions:
- mac80211: fix memory leak of filtered powersave frames
- mac80211: free sta in sta_info_insert_finish() on errors to avoid
sleeping in atomic context
- netlabel: fix an uninitialized variable warning added in -rc4
Previous release - regressions:
- vsock: forward all packets to the host when no H2G is registered,
un-breaking AWS Nitro Enclaves
- net: Exempt multicast addresses from five-second neighbor lifetime
requirement, decreasing the chances neighbor tables fill up
- net/tls: fix corrupted data in recvmsg
- qed: fix ILT configuration of SRC block
- can: m_can: process interrupt only when not runtime suspended
Previous release - always broken:
- page_frag: Recover from memory pressure by not recycling pages
allocating from the reserves
- strncpy_from_user: Mask out bytes after NUL terminator
- ip_tunnels: Set tunnel option flag only when tunnel metadata is
present, always setting it confuses Open vSwitch
- bpf, sockmap:
- Fix partial copy_page_to_iter so progress can still be made
- Fix socket memory accounting and obeying SO_RCVBUF
- net: Have netpoll bring-up DSA management interface
- net: bridge: add missing counters to ndo_get_stats64 callback
- tcp: brr: only postpone PROBE_RTT if RTT is < current min_rtt
- enetc: Workaround MDIO register access HW bug
- net/ncsi: move netlink family registration to a subsystem init,
instead of tying it to driver probe
- net: ftgmac100: unregister NC-SI when removing driver to avoid crash
- lan743x: prevent interrupt storm on open
- lan743x: fix freeing skbs in the wrong context
- net/mlx5e: Fix socket refcount leak on kTLS RX resync
- net: dsa: mv88e6xxx: Avoid VLAN database corruption on 6097
- fix 21 unset return codes and other mistakes on error paths,
mostly detected by the Hulk Robot

selftest/bpf: Test bpf_probe_read_user_str() strips trailing bytes after NUL
Previously, bpf_probe_read_user_str() could potentially overcopy the trailing bytes after the NUL due to how do_strncpy_from_user() does the copy in long-sized strides. The issue has been fixed in the previous commit. This commit adds a selftest that ensures we don't regress bpf_probe_read_user_str() again.

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.

powerpc fixes for CVE-2020-4788
From Daniel's cover letter: IBM Power9 processors can speculatively operate on data in the L1 cache before it has been completely validated, via a way-prediction mechanism. It is not possible for an attacker to determine the contents of impermissible memory using this method, since these systems implement a combination of hardware and software security measures to prevent scenarios where protected data could be leaked. However these measures don't address the scenario where an attacker induces the operating system to speculatively execute instructions using data that the attacker controls. This can be used for example to speculatively bypass "kernel user access prevention" techniques, as discovered by Anthony Steinhauser of Google's Safeside Project. This is not an attack by itself, but there is a possibility it could be used in conjunction with side-channels or other weaknesses in the privileged code to construct an attack. This issue can be mitigated by flushing the L1 cache between privilege boundaries of concern. This patch series flushes the L1 cache on kernel entry (patch 2) and after the kernel performs any user accesses (patch 3). It also adds a self-test and performs some related cleanups. -----BEGIN PGP SIGNATURE----- iQJHBAABCAAxFiEEJFGtCPCthwEv2Y/bUevqPMjhpYAFAl+2aqETHG1wZUBlbGxl cm1hbi5pZC5hdQAKCRBR6+o8yOGlgG+hD/4njSFct2amqWfqDYR9b2OykWmnMQXn geookk5SbItQF7vh1q2SVA6r43s5ZAxgD5fezx4LgG6p3QU39+Tr0RhzUUHWMPDV UNGZK6x/N/GSYeq0bqvMHmVwS0FDjPE8nOtA8Hn2T9mUUsu9G0okpgYPLnEu6rb1 gIyS35zlLBh9obi3MfJzyln/AmCE7hdonKRtLAxvGiERJAyfAG757lrdjrwavyHy mwz+XPl5PF88jfO5cbcZT9gNHmZZPzVsOVwNcstCh2FcwuePv9dWe1pxsBxxKqP5 UXceXPcKM7VlRNmehimq7q/hfbget4RJGGKYPNXeKHOo6yfy7lJPiQV4h+5z2pSs SPP2fQQPq0aubmcO23CXFtZl4WRHQ4pax6opepnpIfC2vZ0HLXJtPrhMKcbFJNTo qPis6HWQPpIuI6l4MJfs+YO9ETxCR31Yd28qFAfPFoHlnQZTfx6NPhw8HKxTbSh2 Svr4X6Y14j3UsQgLTCArCXWAG/hlfRwxDZJ4AvR9EU0HJGDyZ45Y+LTD1N8bbsny zcYfPqWGPIanLcNPNFYIQwDZo7ff08KdmngUvf/Q9om60mP1hsPJMHf6VhPXj4fC 2TZ11fORssSlBSNtIkFkbjEG+aiWtWnz3fN3uSyT50rgGwtDHJzVzLiUWHlZKcxW X73YdxuT8fqQwg== =Yibq -----END PGP SIGNATURE----- Merge tag 'powerpc-cve-2020-4788' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux Pull powerpc fixes from Michael Ellerman: "Fixes for CVE-2020-4788.

spi: Fixes for v5.10
This is a relatively large set of fixes, the bulk of it being a series from Lukas Wunner which fixes confusion with the lifetime of driver data allocated along with the SPI controller structure that's been created as part of the conversion to devm APIs. The simplest fix, explained in detail in Lukas' commit message, is to move to a devm_ function for allocation of the controller and hence driver data in order to push the free of that after anything tries to reference the driver data in the remove path. This results in a relatively large diff due to the addition of a new function but isn't particularly complex. There's also a fix from sven van Asbroeck which fixes yet more fallout from the conflicts between the various different places one can configure the polarity of GPIOs in modern systems. Otherwise everything is fairly small and driver specific. -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAl+2qqsACgkQJNaLcl1U h9DN/gf+P85QtRuWq8hGt9cEywwvPXdYEifxlJuevO+RIzyrI7y6hc2AqmQ/ek2Q kRU39CVLzrm+P8GRX/K6wL8sSQmBVJSt25aWwYKiygidh4eFqmDKC5y/yQY+VIoW /MvFpdFOENDbAjRRK3l5x9BdwXsNPadjl7Ts2FGyjsBOOEWdXf9fApXju7oVHGki oDc35Z5o1DdwTdTD5B/uKP2VmevbrEmBceGZttaSUjyO4kJ9ehe+kJ1DuBu9QrTN GDu/J7oijbtYYfRi6DeMjVfUvvNK9c+6TQay91j0c6ZNW5TuYkZ0XS1vbpjwshQg wWPxA+uQ4YelNgRQ4H+PhzOKo0zv4A== =oG9R -----END PGP SIGNATURE----- Merge tag 'spi-fix-v5.10-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi Pull spi fixes from Mark Brown: "This is a relatively large set of fixes, the bulk of it being a series from Lukas Wunner which fixes confusion with the lifetime of driver data allocated along with the SPI controller structure that's been created as part of the conversion to devm APIs.

case where we can't determine if a regulator is enabled during boot.

ipv6: Remove dependency of ipv6_frag_thdr_truncated on ipv6 module

This dependency is forcing IPV6=y. Remove this dependency by moving ipv6_frag_thdr_truncated out of ipv6. This is the same solution as used with a similar issues: Referring to commit |

ALSA: mixart: Fix mutex deadlock
The code change for switching to non-atomic mode brought the
unexpected mutex deadlock in get_msg(). It converted the spinlock
with the existing mutex, but there were calls with the already holding
the mutex. Since the only place that needs the extra lock is the code
path from snd_mixart_send_msg(), remove the mutex lock in get_msg()
and apply in the caller side for fixing the mutex deadlock.

xfs: don't allow NOWAIT DIO across extent boundaries
Jens has reported a situation where partial direct IOs can be issued and completed yet still return -EAGAIN. We don't want this to report a short IO as we want XFS to complete user DIO entirely or not at all. This partial IO situation can occur on a write IO that is split across an allocated extent and a hole, and the second mapping is returning EAGAIN because allocation would be required. The trivial reproducer: $ sudo xfs_io -fdt -c "pwrite 0 4k" -c "pwrite -V 1 -b 8k -N 0 8k" /mnt/scr/foo wrote 4096/4096 bytes at offset 0 4 KiB, 1 ops; 0.0001 sec (27.509 MiB/sec and 7042.2535 ops/sec) pwrite: Resource temporarily unavailable $ The pwritev2(0, 8kB, RWF_NOWAIT) call returns EAGAIN having done the first 4kB write: xfs_file_direct_write: dev 259:1 ino 0x83 size 0x1000 offset 0x0 count 0x2000 iomap_apply: dev 259:1 ino 0x83 pos 0 length 8192 flags WRITE|DIRECT|NOWAIT (0x31) ops xfs_direct_write_iomap_ops caller iomap_dio_rw actor iomap_dio_actor xfs_ilock_nowait: dev 259:1 ino 0x83 flags ILOCK_SHARED caller xfs_ilock_for_iomap xfs_iunlock: dev 259:1 ino 0x83 flags ILOCK_SHARED caller xfs_direct_write_iomap_begin xfs_iomap_found: dev 259:1 ino 0x83 size 0x1000 offset 0x0 count 8192 fork data startoff 0x0 startblock 24 blockcount 0x1 iomap_apply_dstmap: dev 259:1 ino 0x83 bdev 259:1 addr 102400 offset 0 length 4096 type MAPPED flags DIRTY Here the first iomap loop has mapped the first 4kB of the file and issued the IO, and we enter the second iomap_apply loop: iomap_apply: dev 259:1 ino 0x83 pos 4096 length 4096 flags WRITE|DIRECT|NOWAIT (0x31) ops xfs_direct_write_iomap_ops caller iomap_dio_rw actor iomap_dio_actor xfs_ilock_nowait: dev 259:1 ino 0x83 flags ILOCK_SHARED caller xfs_ilock_for_iomap xfs_iunlock: dev 259:1 ino 0x83 flags ILOCK_SHARED caller xfs_direct_write_iomap_begin And we exit with -EAGAIN out because we hit the allocate case trying to make the second 4kB block. Then IO completes on the first 4kB and the original IO context completes and unlocks the inode, returning -EAGAIN to userspace: xfs_end_io_direct_write: dev 259:1 ino 0x83 isize 0x1000 disize 0x1000 offset 0x0 count 4096 xfs_iunlock: dev 259:1 ino 0x83 flags IOLOCK_SHARED caller xfs_file_dio_aio_write There are other vectors to the same problem when we re-enter the mapping code if we have to make multiple mappinfs under NOWAIT conditions. e.g. failing trylocks, COW extents being found, allocation being required, and so on. Avoid all these potential problems by only allowing IOMAP_NOWAIT IO to go ahead if the mapping we retrieve for the IO spans an entire allocated extent. This avoids the possibility of subsequent mappings to complete the IO from triggering NOWAIT semantics by any means as NOWAIT IO will now only enter the mapping code once per NOWAIT IO.

libbpf: Fix VERSIONED_SYM_COUNT number parsing
We remove "other info" from "readelf -s --wide" output when parsing GLOBAL_SYM_COUNT variable, which was added in [1]. But we don't do that for VERSIONED_SYM_COUNT and it's failing the check_abi target on powerpc Fedora 33. The extra "other info" wasn't problem for VERSIONED_SYM_COUNT parsing until commit [2] added awk in the pipe, which assumes that the last column is symbol, but it can be "other info". Adding "other info" removal for VERSIONED_SYM_COUNT the same way as we did for GLOBAL_SYM_COUNT parsing. [1] |
