Lukas Bulwahn c6cc4f7241 alpha: remove the needless aliases osf_{readv,writev}
Commit 987f20a9dc ("a.out: Remove the a.out implementation") removes
CONFIG_OSF4_COMPAT and its functionality. Hence, sys_osf_{readv,writev}
are now just aliases of sys_{readv,writev}.

Remove these needless aliases.

Juergen Gross 3fac3734c4 xen/pv: support selecting safe/unsafe msr accesses
Instead of always doing the safe variants for reading and writing MSRs
in Xen PV guests, make the behavior controllable via Kconfig option
and a boot parameter.

The default will be the current behavior, which is to always use the
safe variant.

Refactor and rename xen_read_msr_safe() and xen_write_msr_safe() to
support both cases of MSR accesses, safe ones and potentially GP-fault
generating ones.

This will prepare to no longer swallow GPs silently in xen_read_msr()

Juergen Gross f90d98bdd0 xen/pv: fix vendor checks for pmu emulation
The CPU vendor checks for pmu emulation are rather limited today, as
the assumption seems to be that only Intel and AMD are existing and/or
supported vendors.

Fix that by handling Centaur and Zhaoxin CPUs the same way as Intel,
and Hygon the same way as AMD.

While at it fix the return type of is_intel_pmu_msr().

Kalle Valo abf93f3694 wifi: ath11k: mac: fix reading 16 bytes from a region of size 0 warning
Linaro reported stringop-overread warnings in ath11k (this is one of many):

drivers/net/wireless/ath/ath11k/mac.c:2238:29: error: 'ath11k_peer_assoc_h_he_limit' reading 16 bytes from a region of size 0 [-Werror=stringop-overread]

My further investigation showed that these warnings happen on GCC 11.3 but not
with GCC 12.2, and with only the kernel config Linaro provided:

https://builds.tuxbuild.com/2F4W7nZHNx3T88RB0gaCZ9hBX6c/config

I saw the same warnings both with arm64 and x86_64 builds and KASAN seems to be
the reason triggering these warnings with GCC 11.  Nobody else has reported
this so this seems to be quite rare corner case. I don't know what specific
commit started emitting this warning so I can't provide a Fixes tag. The
function hasn't been touched for a year.

I decided to workaround this by converting the pointer to a new array in stack,
and then copying the data to the new array. It's only 16 bytes anyway and this
is executed during association, so not in a hotpath.

So, it is necessary to extend the applied solution with commit 14a3aacf51
("iwlwifi: mvm: fix double list_add at iwl_mvm_mac_wake_tx_queue")
to all other cases where the station queues are invalidated and the related
lists are not emptied. Because, otherwise as before, if some new element is
added later to the list in iwl_mvm_mac_wake_tx_queue, it can match with the
old one and produce the same commented BUG.

That is, in order to avoid this problem completely, we must also remove the
related lists for the other cases when station queues are invalidated.

Checking the relevant rxd bits for the checksum information only indicates
if the checksum verification was performed by the hardware and doesn't show
actual checksum errors. Checksum errors are indicated in the info field of
the DMA descriptor. Fix packets erroneously marked as CHECKSUM_UNNECESSARY
by checking the extra bits as well.
Those bits are only passed to the driver for MMIO devices at the moment, so
limit checksum offload to those.

Felix Fietkau 47c44088ac wifi: mt76: fix receiving LLC packets on mt7615/mt7915
When 802.3 decap offload is enabled, the hardware indicates header translation
failure, whenever either the LLC-SNAP header was not found, or a VLAN header
with an unregcognized tag is present.
In that case, the hardware inserts a 2-byte length fields after the MAC
addresses. For VLAN packets, this tag needs to be removed. However,
for 802.3 LLC packets, the length bytes should be preserved, since there
is no separate ethertype field in the data.
This fixes an issue where the length field was omitted for LLC frames, causing
them to be malformed after hardware decap.

Anssi Hannula 455561fb61 can: kvaser_usb_leaf: Fix TX queue out of sync after restart
The TX queue seems to be implicitly flushed by the hardware during
bus-off or bus-off recovery, but the driver does not reset the TX
bookkeeping.

Despite not resetting TX bookkeeping the driver still re-enables TX
queue unconditionally, leading to "cannot find free context" /
NETDEV_TX_BUSY errors if the TX queue was full at bus-off time.

Fix that by resetting TX bookkeeping on CAN restart.

Anssi Hannula cd7f30e174 can: kvaser_usb: Fix use of uninitialized completion
flush_comp is initialized when CMD_FLUSH_QUEUE is sent to the device and
completed when the device sends CMD_FLUSH_QUEUE_RESP.

This causes completion of uninitialized completion if the device sends
CMD_FLUSH_QUEUE_RESP before CMD_FLUSH_QUEUE is ever sent (e.g. as a
response to a flush by a previously bound driver, or a misbehaving
device).

Fix that by initializing flush_comp in kvaser_usb_init_one() like the
other completions.

This issue is only triggerable after RX URBs have been set up, i.e. the
interface has been opened at least once.

Anssi Hannula 1499ecaea9 can: kvaser_usb_leaf: Fix overread with an invalid command
For command events read from the device,
kvaser_usb_leaf_read_bulk_callback() verifies that cmd->len does not
exceed the size of the received data, but the actual kvaser_cmd handlers
will happily read any kvaser_cmd fields without checking for cmd->len.

This can cause an overread if the last cmd in the buffer is shorter than
expected for the command type (with cmd->len showing the actual short
size).

Maximum overread seems to be 22 bytes (CMD_LEAF_LOG_MESSAGE), some of
which are delivered to userspace as-is.

Fix that by verifying the length of command before handling it.

This issue can only occur after RX URBs have been set up, i.e. the
interface has been opened at least once.

Linus Torvalds 5d170fe435 f2fs-for-6.1-rc1
This round looks fairly small comparing to the previous updates which includes
 mostly minor bug fixes. Nevertheless, as we've still interested in improving
 the stability, Chao added some debugging methods to diagnoze subtle runtime
 inconsistency problem.
 
 Enhancement
  - store all the corruption or failure reasons in superblock
  - detect meta inode, summary info, and block address inconsistency
  - increase the limit for reserve_root for low-end devices
  - add the number of compressed IO in iostat
 
 Bug fix
  - DIO write fix for zoned devices
  - do out-of-place writes for cold files
  - fix some stat updates (FS_CP_DATA_IO, dirty page count)
  - fix race condition on setting FI_NO_EXTENT flag
  - fix data races when freezing super
  - fix wrong continue condition check in GC
  - do not allow ATGC for LFS mode
 
 In addition, there're some code enhancement and clean-ups as usual.

The highlight of this PR is Christian's patch to allocate smaller buffers

 buffers when just 4 or 8k would be more than enough; this brings in nice
 performance improvements.

 "There are some small things here, plus one big one.

  The big one detected and refused to create W+X kernel mappings. This
  caused a bit of trouble and it is entirely disabled on 32-bit due to
  known unfixable EFI issues. It also oopsed on some systemd eBPF use,
  which kept some users from booting.

  The eBPF issue is fixed, but those troubles were caught relatively
  recently which made me nervous that there are more lurking. The final

Andrii Nakryiko f6ac03ebeb Merge branch 'Add _opts variant for bpf_*_get_fd_by_id()'
Roberto Sassu says:

====================
From: Roberto Sassu <roberto.sassu@huawei.com>

Add the _opts variant for bpf_*_get_fd_by_id() functions, to be able to
pass to the kernel more options, when requesting a fd of an eBPF object.

Pass the options through a newly introduced structure,
bpf_get_fd_by_id_opts, which currently contains open_flags (the other two
members are for compatibility and for padding).

open_flags allows the caller to request specific permissions to access a
map (e.g. read-only). This is useful for example in the situation where a
map is write-protected.

Besides patches 2-6, which introduce the new variants and the data
structure, patch 1 fixes the LIBBPF_1.0.0 declaration in libbpf.map.

Changelog

v1:
 - Don't CC stable kernel mailing list for patch 1 (suggested by Andrii)
 - Rename bpf_get_fd_opts struct to bpf_get_fd_by_id_opts (suggested by
   Andrii)
 - Move declaration of _opts variants after non-opts variants (suggested by
   Andrii)
 - Correctly initialize bpf_map_info, fix style issues, use map from
   skeleton, check valid fd in the test (suggested by Andrii)
 - Rename libbpf_get_fd_opts test to libbpf_get_fd_by_id_opts

Roberto Sassu a9c7c18b57 selftests/bpf: Add tests for _opts variants of bpf_*_get_fd_by_id()
Introduce the data_input map, write-protected with a small eBPF program
implementing the lsm/bpf_map hook.

Then, ensure that bpf_map_get_fd_by_id() and bpf_map_get_fd_by_id_opts()
with NULL opts don't succeed due to requesting read-write access to the
write-protected map. Also, ensure that bpf_map_get_fd_by_id_opts() with
open_flags in opts set to BPF_F_RDONLY instead succeeds.

After obtaining a read-only fd, ensure that only map lookup succeeds and
not update. Ensure that update works only with the read-write fd obtained
at program loading time, when the write protection was not yet enabled.

Finally, ensure that the other _opts variants of bpf_*_get_fd_by_id() don't
work if the BPF_F_RDONLY flag is set in opts (due to the kernel not
handling the open_flags member of bpf_attr).

Introduce bpf_link_get_fd_by_id_opts(), for symmetry with

bpf_link_get_fd_by_id(), and call bpf_link_get_fd_by_id_opts() with NULL as
opts argument, to prevent setting open_flags.

Currently, the kernel does not support non-zero open_flags for
bpf_link_get_fd_by_id_opts(), and a call with them will result in an error
returned by the bpf() system call. The caller should always pass zero
open_flags.

Linus Torvalds d4013bc4d4 bitmap patches for v6.1-rc1
From Phil Auld:
 drivers/base: Fix unsigned comparison to -1 in CPUMAP_FILE_MAX_BYTES
 
 From me:
 cpumask: cleanup nr_cpu_ids vs nr_cpumask_bits mess
 
 This series cleans that mess and adds new config FORCE_NR_CPUS that
 allows to optimize cpumask subsystem if the number of CPUs is known
 at compile-time.
 
 From me:
 lib: optimize find_bit() functions
 
 Reworks find_bit() functions based on new FIND_{FIRST,NEXT}_BIT() macros.
 
 From me:
 lib/find: add find_nth_bit()
 
 Adds find_nth_bit(), which is ~70 times faster than bitcounting with
 for_each() loop:
         for_each_set_bit(bit, mask, size)
                 if (n-- == 0)
                         return bit;
 
 Also adds bitmap_weight_and() to let people replace this pattern:
 	tmp = bitmap_alloc(nbits);
 	bitmap_and(tmp, map1, map2, nbits);
 	weight = bitmap_weight(tmp, nbits);
 	bitmap_free(tmp);
 with a single bitmap_weight_and() call.
 
 From me:
 cpumask: repair cpumask_check()
 
 After switching cpumask to use nr_cpu_ids, cpumask_check() started
 generating many false-positive warnings. This series fixes it.
 
 From Valentin Schneider:
 bitmap,cpumask: Add for_each_cpu_andnot() and for_each_cpu_andnot()
 
 Extends the API with one more function and applies it in sched/core.
