cfg80211: fix locking in netlink owner interface destruction
Harald Arnesen reported [1] a deadlock at reboot time, and after
he captured a stack trace a picture developed of what's going on:
The distribution he's using is using iwd (not wpa_supplicant) to
manage wireless. iwd will usually use the "socket owner" option
when it creates new interfaces, so that they're automatically
destroyed when it quits (unexpectedly or otherwise). This is also
done by wpa_supplicant, but it doesn't do it for the normal one,
only for additional ones, which is different with iwd.
Anyway, during shutdown, iwd quits while the netdev is still UP,
i.e. IFF_UP is set. This causes the stack trace that Linus so
nicely transcribed from the pictures:
cfg80211_destroy_iface_wk() takes wiphy_lock
-> cfg80211_destroy_ifaces()
->ieee80211_del_iface
->ieeee80211_if_remove
->cfg80211_unregister_wdev
->unregister_netdevice_queue
->dev_close_many
->__dev_close_many
->raw_notifier_call_chain
->cfg80211_netdev_notifier_call
and that last call tries to take wiphy_lock again.

bpf, cpumap: Bulk skb using netif_receive_skb_list
Rely on netif_receive_skb_list routine to send skbs converted from xdp_frames in cpu_map_kthread_run in order to improve i-cache usage. The proposed patch has been tested running xdp_redirect_cpu bpf sample available in the kernel tree that is used to redirect UDP frames from ixgbe driver to a cpumap entry and then to the networking stack. UDP frames are generated using pktgen. Packets are discarded by the UDP layer. $ xdp_redirect_cpu --cpu <cpu> --progname xdp_cpu_map0 --dev <eth> bpf-next: ~2.35Mpps bpf-next + cpumap skb-list: ~2.72Mpps Rename drops counter in kmem_alloc_drops since now it reports just kmem_cache_alloc_bulk failures Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Acked-by: Jesper Dangaard Brouer <brouer@redhat.com> Link: https://lore.kernel.org/bpf/c729f83e5d7482d9329e0f165bdbe5adcefd1510.1619169700.git.lorenzo@kernel.org |

powerpc/papr_scm: Mark nvdimm as unarmed if needed during probe
In case an nvdimm is found to be unarmed during probe then set its NDD_UNARMED flag before nvdimm_create(). This would enforce a read-only access to the ndimm region. Presently even if an nvdimm is unarmed its not marked as read-only on ppc64 guests. The patch updates papr_scm_nvdimm_init() to force query of nvdimm health via __drc_pmem_query_health() and if nvdimm is found to be unarmed then set the nvdimm flag ND_UNARMED for nvdimm_create().

io_uring: maintain drain logic for multishot poll requests
Now that we have multishot poll requests, one SQE can emit multiple
CQEs. given below example:
sqe0(multishot poll)-->sqe1-->sqe2(drain req)
sqe2 is designed to issue after sqe0 and sqe1 completed, but since sqe0
is a multishot poll request, sqe2 may be issued after sqe0's event
triggered twice before sqe1 completed. This isn't what users leverage
drain requests for.
Here the solution is to wait for multishot poll requests fully
completed.
To achieve this, we should reconsider the req_need_defer equation, the
original one is:
all_sqes(excluding dropped ones) == all_cqes(including dropped ones)
This means we issue a drain request when all the previous submitted
SQEs have generated their CQEs.
Now we should consider multishot requests, we deduct all the multishot
CQEs except the cancellation one, In this way a multishot poll request
behave like a normal request, so:
all_sqes == all_cqes - multishot_cqes(except cancellations)
Here we introduce cq_extra for it.

io_uring: Check current->io_uring in io_uring_cancel_sqpoll
syzkaller identified KASAN: null-ptr-deref Write in io_uring_cancel_sqpoll. io_uring_cancel_sqpoll is called by io_sq_thread before calling io_uring_alloc_task_context. This leads to current->io_uring being NULL. io_uring_cancel_sqpoll should not have to deal with threads where current->io_uring is NULL. In order to cast a wider safety net, perform input sanitisation directly in io_uring_cancel_sqpoll and return for NULL value of current->io_uring. This is safe since if current->io_uring isn't set, then there's no way for the task to have submitted any requests.

exfat: speed up iterate/lookup by fixing start point of traversing cluster chain
When directory iterate and lookup is called, there's a buggy rewinding of start point for traversing cluster chain to the parent directory entry's first cluster. This caused repeated cluster chain traversing from the first entry of the parent directory that would show worse performance if huge amounts of files exist under the parent directory. Fix not to rewind, make continue from currently referenced cluster and dir entry. Tested with 50,000 files under single directory / 256GB sdcard, with command "time ls -l > /dev/null", Before : 0m08.69s real 0m00.27s user 0m05.91s system After : 0m07.01s real 0m00.25s user 0m04.34s system Signed-off-by: Hyeongseok Kim <hyeongseok@gmail.com> Reviewed-by: Sungjong Seo <sj1557.seo@samsung.com> Signed-off-by: Namjae Jeon <namjae.jeon@samsung.com> |

Merge branch 'CO-RE relocation selftests fixes'
Andrii Nakryiko says: ==================== Lorenz Bauer noticed that core_reloc selftest has two inverted CHECK() conditions, allowing failing tests to pass unnoticed. Fixing that opened up few long-standing (field existence and direct memory bitfields) and one recent failures (BTF_KIND_FLOAT relos). This patch set fixes core_reloc selftest to capture such failures reliably in the future. It also fixes all the newly failing tests. See individual patches for details. This patch set also completes a set of ASSERT_xxx() macros, so now there should be a very little reason to use verbose and error-prone generic CHECK() macro. v1->v2: - updated bpf_core_fields_are_compat() comment to mention FLOAT (Lorenz).

selftests/bpf: Fix field existence CO-RE reloc tests
Negative field existence cases for have a broken assumption that FIELD_EXISTS
CO-RE relo will fail for fields that match the name but have incompatible type
signature. That's not how CO-RE relocations generally behave. Types and fields
that match by name but not by expected type are treated as non-matching
candidates and are skipped. Error later is reported if no matching candidate
was found. That's what happens for most relocations, but existence relocations
(FIELD_EXISTS and TYPE_EXISTS) are more permissive and they are designed to
return 0 or 1, depending if a match is found. This allows to handle
name-conflicting but incompatible types in BPF code easily. Combined with
___flavor suffixes, it's possible to handle pretty much any structural type
changes in kernel within the compiled once BPF source code.
So, long story short, negative field existence test cases are invalid in their
assumptions, so this patch reworks them into a single consolidated positive
case that doesn't match any of the fields.

selftests/bpf: Fix BPF_CORE_READ_BITFIELD() macro
Fix BPF_CORE_READ_BITFIELD() macro used for reading CO-RE-relocatable
bitfields. Missing breaks in a switch caused 8-byte reads always. This can
confuse libbpf because it does strict checks that memory load size corresponds
to the original size of the field, which in this case quite often would be
wrong.
After fixing that, we run into another problem, which quite subtle, so worth
documenting here. The issue is in Clang optimization and CO-RE relocation
interactions. Without that asm volatile construct (also known as
barrier_var()), Clang will re-order BYTE_OFFSET and BYTE_SIZE relocations and
will apply BYTE_OFFSET 4 times for each switch case arm. This will result in
the same error from libbpf about mismatch of memory load size and original
field size. I.e., if we were reading u32, we'd still have *(u8 *), *(u16 *),
*(u32 *), and *(u64 *) memory loads, three of which will fail. Using
barrier_var() forces Clang to apply BYTE_OFFSET relocation first (and once) to
calculate p, after which value of p is used without relocation in each of
switch case arms, doing appropiately-sized memory load.
Here's the list of relevant relocations and pieces of generated BPF code
before and after this patch for test_core_reloc_bitfields_direct selftests.

This should cover most scenarios where people fall back to error-prone CHECK()s. Also extend ASSERT_ERR() to print out errno, in addition to direct error. Also convert few CHECK() instances to ensure new ASSERT_xxx() variants work as expected. Subsequent patch will also use ASSERT_TRUE/ASSERT_FALSE more extensively.

using conversions in the core rather than open coding in drivers.
Otherwise it's a good stack of cleanups and fixes plus a few new
drivers.
The conversion to new style transfer delay will cause an issue with a
newly added staging driver which has a straightforward resolution in
-next.

netfs: Miscellaneous fixes
Fix some miscellaneous things in the new netfs lib[1]:
(1) The kerneldoc for netfs_readpage() shouldn't say netfs_page().
(2) netfs_readpage() can get an integer overflow on 32-bit when it
multiplies page_index(page) by PAGE_SIZE. It should use
page_file_offset() instead.
(3) netfs_write_begin() should use page_offset() to avoid the same
overflow.
Note that netfs_readpage() needs to use page_file_offset() rather than
page_offset() as it may see swap-over-NFS.

Pull power management updates from Rafael Wysocki:
"These add some new hardware support (for example, IceLake-D idle
states in intel_idle), fix some issues (for example, the handling of
negative "sleep length" values in cpuidle governors), add new
functionality to the existing drivers (for example, scale-invariance
support in the ACPI CPPC cpufreq driver) and clean up code all over.

hwmon updates for v5.13
The most notable change is the removal of the amd_energy driver. It was
rendered all but unusable by making its attributes privileged-only to work
around a security issue. A suggested remedy was rejected by AMD, so the
only real solution was to remove the driver. For the future, we'll have
to make sure that no privileged-access-only drivers are accepted into the
hwmon subsystem in the first place. The hwmon ABI document was updated
accordingly.
Other changes:
PMBus drivers:
- Added driver for MAX15301
- Added driver for BluTek BPA-RS600
- Added driver for fsp-3y PSUs and PDUs
- Added driver for Infineon IR36021
- Added driver for ST STPDDC60
- Added support for TI TPS53676 to tps53679 driver
- Introduced PMBUS symbol namespace
This was made necessary by a suggestion to use its exported functions
from outside the hwmon subsystem.
- Minor improvements and bug fixes
New drivers:
- Driver for NZXT Kraken X42/X52/X62/X72
Driver enhancements:
- Added support for Intel D5005 to intel-m10-bmc-hwmon driver
- Added support for NCT6686D to nct6683 driver
Other:
- Converted sch5627 and amd9240 drivers to hwmon_device_register_with_info()
- Added support for fan drawers capability and present registers to mlxreg-fan
driver
- Added Dell Latitude E7440 to fan control whitelist in dell-smm driver
- Replaced snprintf in show functions with sysfs_emit
Done with coccinelle script for all drivers to preempt endless per-driver
submissions of the same change.
- Use kobj_to_dev()
Another coccinelle based change to preempt endless per-driver submissions
of the same change.
- Various minor fixes and improvements

iov_iter: Four fixes for ITER_XARRAY
Fix four things[1] in the patch that adds ITER_XARRAY[2]:
(1) Remove the address_space struct predeclaration. This is a holdover
from when it was ITER_MAPPING.
(2) Fix _copy_mc_to_iter() so that the xarray segment updates count and
iov_offset in the iterator before returning.
(3) Fix iov_iter_alignment() to not loop in the xarray case. Because the
middle pages are all whole pages, only the end pages need be
considered - and this can be reduced to just looking at the start
position in the xarray and the iteration size.
(4) Fix iov_iter_advance() to limit the size of the advance to no more
than the remaining iteration size.

powerpc: Free fdt on error in elf64_load()
There are a few "goto out;" statements before the local variable "fdt"
is initialized through the call to of_kexec_alloc_and_setup_fdt() in
elf64_load(). This will result in an uninitialized "fdt" being passed
to kvfree() in this function if there is an error before the call to
of_kexec_alloc_and_setup_fdt().
If there is any error after fdt is allocated, but before it is
saved in the arch specific kimage struct, free the fdt.

Merge tag 'for-5.13-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux
Pull btrfs updates from David Sterba:
"The updates this time are mostly stabilization, preparation and minor
improvements.
User visible improvements:
- readahead for send, improving run time of full send by 10% and for
incremental by 25%
- make reflinks respect O_SYNC, O_DSYNC and S_SYNC flags
- export supported sectorsize values in sysfs (currently only page
size, more once full subpage support lands)
- more graceful errors and warnings on 32bit systems when logical
addresses for metadata reach the limit posed by unsigned long in
page::index
- error: fail mount if there's a metadata block beyond the limit
- error: new metadata block would be at unreachable address
- warn when 5/8th of the limit is reached, for 4K page systems
it's 10T, for 64K page it's 160T
- zoned mode
- relocated zones get reset at the end instead of discard
- automatic background reclaim of zones that have 75%+ of unusable
space, the threshold is tunable in sysfs
Fixes:
- fsync and tree mod log fixes
- fix inefficient preemptive reclaim calculations
- fix exhaustion of the system chunk array due to concurrent
allocations
- fix fallback to no compression when racing with remount
- preemptive fix for dm-crypt on zoned device that does not properly
advertise zoned support
Core changes:
- add inode lock to synchronize mmap and other block updates (eg.
deduplication, fallocate, fsync)
- kmap conversions to new kmap_local API
- subpage support (continued)
- new helpers for page state/extent buffer tracking
- metadata changes now support read and write
- error handling through out relocation call paths
- many other cleanups and code simplifications"

"In this cycle, we would like to introduce a new feature called big

different pcluster size can be selected for each (sub-)files by
design.

which has been verified but I'd like warn it as experimental for a
while. This matches erofs-utils dev branch and I'll also release a new
userspace version for this later.
Apart from that, several improvements are also included: eg complete a
missing case for inplace I/O, optimize endio decompression logic for
non-atomic contexts and support adjustable sliding window size, ... In
addition to those, there are some cleanups as always.

net:emac/emac-mac: Fix a use after free in emac_mac_tx_buf_send
In emac_mac_tx_buf_send, it calls emac_tx_fill_tpd(..,skb,..).
If some error happens in emac_tx_fill_tpd(), the skb will be freed via
dev_kfree_skb(skb) in error branch of emac_tx_fill_tpd().
But the freed skb is still used via skb->len by netdev_sent_queue(,skb->len).
As i observed that emac_tx_fill_tpd() haven't modified the value of skb->len,
thus my patch assigns skb->len to 'len' before the possible free and
use 'len' instead of skb->len later.
