…aths

Several iso_pi(sk) fields (qos, qos_user_set, bc_sid, base, base_len,
sync_handle, bc_num_bis) are written under lock_sock in
iso_sock_setsockopt() and iso_sock_bind(), but read and written under
hci_dev_lock only in two other paths:

  - iso_connect_bis() / iso_connect_cis(), invoked from connect(2),
    read qos/base/bc_sid and reset qos to default_qos on the
    qos_user_set validation failure -- all without lock_sock.

  - iso_connect_ind(), invoked from hci_rx_work, writes sync_handle,
    bc_sid, qos.bcast.encryption, bc_num_bis, base and base_len on
    PA_SYNC_ESTABLISHED / PAST_RECEIVED / BIG_INFO_ADV_REPORT /
    PER_ADV_REPORT events. The BIG_INFO handler additionally passes
    &iso_pi(sk)->qos together with sync_handle / bc_num_bis / bc_bis
    to hci_conn_big_create_sync() while setsockopt may be mutating
    them.

Acquire lock_sock around the affected accesses in both paths.

The locking order hci_dev_lock -> lock_sock matches the existing
iso_conn_big_sync() precedent, whose comment documents the same
requirement for hci_conn_big_create_sync(). The HCI connect/bind
helpers do not wait for command completion -- they enqueue work via
hci_cmd_sync_queue{,_once}() / hci_le_create_cis_pending() and
return -- so the added hold time is comparable to iso_conn_big_sync().

The xfstests' test-case generic/637 fails with error:

FSTYP -- hfsplus
PLATFORM -- Linux/x86_64 hfsplus-testing-0001 6.15.0-rc4+ #8 SMP PREEMPT_DYNAMIC Thu May 1 16:43:22 PDT 2025
MKFS_OPTIONS -- /dev/loop51
MOUNT_OPTIONS -- /dev/loop51 /mnt/scratch

QA output created by 637
entries 7 and 8 have duplicate d_off 8
Found unlinked files in open dir (see xfstests-dev/results//generic/637.full for details)

Debugging of the hfsplus_readdir() logic showed this:

hfsplus: hfsplus_readdir(): 163 ctx->pos 0
hfsplus: hfsplus_readdir(): 189 ctx->pos 1
hfsplus: hfsplus_readdir(): 264 ctx->pos 2, ino 18
hfsplus: hfsplus_readdir(): 264 ctx->pos 3, ino 19
hfsplus: hfsplus_readdir(): 264 ctx->pos 4, ino 28
hfsplus: hfsplus_readdir(): 264 ctx->pos 5, ino 118
hfsplus: hfsplus_readdir(): 264 ctx->pos 6, ino 29
hfsplus: hfsplus_readdir(): 264 ctx->pos 7, ino 30
hfsplus: hfsplus_readdir(): 264 ctx->pos 8, ino 31
hfsplus: hfsplus_readdir(): 304 ctx->pos 8
hfsplus: hfsplus_unlink():420 dir->i_ino 17, inode->i_ino 28
hfsplus: hfsplus_readdir(): 141 ctx->pos 7
hfsplus: hfsplus_readdir(): 264 ctx->pos 7, ino 31
hfsplus: hfsplus_readdir(): 264 ctx->pos 8, ino 32
hfsplus: hfsplus_readdir(): 264 ctx->pos 9, ino 33

It means that hfsplus_readdir() stopped the processing of
folder's items on ctx->pos 8, then, item with ino 28 has
been deleted and hfsplus_readdir() re-started the logic
from ctx->pos 7. As a result, previous and new sets of
folder's items have overlapping values for the case of
d_off 8.

Currently, HFS+ has very complicated and fragile logic
of rd->file->f_pos correction in hfsplus_delete_cat().
This patch removes this logic and it stores the current
pos into hfsplus_readdir_data. Finally, if rd->pos == ctx->pos
then hfsplus_readdir() tries to find the position in
b-tree's node by means of hfsplus_cat_key. This position is
used to re-start the folder's content traversal.

    [ 447.220837] Disabling IRQ #44

The affected IOEXP nodes are missing interrupt pin configuration in
the device tree, causing the interrupt line to remain asserted and
resulting in repeated unhandled IRQ events.

Add the required interrupt-related properties for the affected IOEXP
devices to ensure proper interrupt handling and prevent the IRQ from
being disabled.

It seems that this happens on some systems for some reason, when the
ASSERT() macro calls the inline function verify_assert_printk_format()
to evaluate the format string and arguments, causing the NULL pointer
dereference on node->eb.

So change the assertion to check for a NULL node->eb before dereferencing
it. Also, while at it, make the assertion more useful by printing the
owner of the extent buffer as well as its level.
