for many other things, including iomap_begin and end, which causes a

simultaneous opens (gfs2_open -> gfs2_open_common -> gfs2_qa_get) can

gfs2: Return more useful errors from gfs2_rgrp_send_discards()
The bug that 895ee5709 ("gfs2: Make sure FITRIM minlen is rounded up to
fs block size") fixes was a little confusing as the user saw
"Input/output error" which masked the -EINVAL that sb_issue_discard()
returned.
sb_issue_discard() can fail for various reasons, so we should return its
return value from gfs2_rgrp_send_discards() to avoid all errors being
reported as IO errors.
This improves error reporting for FITRIM and makes no difference to the
-o discard code path because the return value from
gfs2_rgrp_send_discards() gets thrown away in that case (and the option
switches off). Presumably that's why it was ok to just return -EIO in
the past, before FITRIM was implemented.

We're having unresolved issues with the glock holder auto-demotion mechanism

for avoiding frequent short reads and writes until commit cc8f96fca13e
("gfs2: No short reads or writes upon glock contention"). Since then,
when the inode glock is lost, it is simply re-acquired and the operation
is resumed. This means that apart from the performance penalty, we
might as well drop the inode glock before faulting in pages, and
re-acquire it afterwards.

In gfs2_file_buffered_write, to increase the likelihood that all the
user memory we're trying to write will be resident in memory, carry out
the write in chunks and fault in each chunk of user memory before trying
to write it. Otherwise, some workloads will trigger frequent short
"internal" writes, causing filesystem blocks to be allocated and then
partially deallocated again when writing into holes, which is wasteful
and breaks reservations.
Neither the chunked writes nor any of the short "internal" writes are
user visible.

blocks that have been allocated for this write but haven't been used.
To compute the end of the allocation, gfs2_iomap_end() incorrectly
rounded the end of the attempted write down to the next block boundary
to arrive at the end of the allocation. It would have to round up, but
the end of the allocation is also available as iomap->offset +
iomap->length, so just use that instead.
In addition, use round_up() for computing the start of the unused range.

context stayed alive, but ctx->netdev became NULL, and the offload was
torn down without a proper fallback, so a bug was present, but a
different kind of bug.
Due to misunderstanding of the issue, the original patch dropped the
refcount_dec_and_test line for the context to avoid the alleged
premature deallocation. That line has to be restored, because it matches
the refcount_inc_not_zero from the same function, otherwise the contexts
that survived tls_device_down are leaked.
This patch fixes the described issue by restoring refcount_dec_and_test.
After this change, there is no leak anymore, and the fallback to
software kTLS still works.

mlxsw: Avoid warning during ip6gre device removal
IPv6 addresses which are used for tunnels are stored in a hash table
with reference counting. When a new GRE tunnel is configured, the driver
is notified and configures it in hardware.
Currently, any change in the tunnel is not applied in the driver. It
means that if the remote address is changed, the driver is not aware of
this change and the first address will be used.
This behavior results in a warning [1] in scenarios such as the
following:
# ip link add name gre1 type ip6gre local 2000::3 remote 2000::fffe tos inherit ttl inherit
# ip link set name gre1 type ip6gre local 2000::3 remote 2000::ffff ttl inherit
# ip link delete gre1
The change of the address is not applied in the driver. Currently, the
driver uses the remote address which is stored in the 'parms' of the
overlay device. When the tunnel is removed, the new IPv6 address is
used, the driver tries to release it, but as it is not aware of the
change, this address is not configured and it warns about releasing non
existing IPv6 address.
Fix it by using the IPv6 address which is cached in the IPIP entry, this
address is the last one that the driver used, so even in cases such the
above, the first address will be released, without any warning.
The ID register table should have one entry per ID register but
currently has two entries for ID_AA64ISAR2_EL1. Only one entry has an
override, and get_arm64_ftr_reg() can end up choosing the other, causing
the override to be ignored. Fix this by removing the duplicate entry.
While here, also make the check in sort_ftr_regs() more strict so that
duplicate entries can't be added in the future.

Bluetooth: Fix the creation of hdev->name
Set a size limit of 8 bytes of the written buffer to "hdev->name"
including the terminating null byte, as the size of "hdev->name" is 8
bytes. If an id value which is greater than 9999 is allocated,
then the "snprintf(hdev->name, sizeof(hdev->name), "hci%d", id)"
function call would lead to a truncation of the id value in decimal
notation.
Set an explicit maximum id parameter in the id allocation function call.
The id allocation function defines the maximum allocated id value as the
maximum id parameter value minus one. Therefore, HCI_MAX_ID is defined
as 10000.

i40e: i40e_main: fix a missing check on list iterator
The bug is here:
ret = i40e_add_macvlan_filter(hw, ch->seid, vdev->dev_addr, &aq_err);
The list iterator 'ch' will point to a bogus position containing
HEAD if the list is empty or no element is found. This case must
be checked before any use of the iterator, otherwise it will
lead to a invalid memory access.
To fix this bug, use a new variable 'iter' as the list iterator,
while use the origin variable 'ch' as a dedicated pointer to
point to the found element.

net/sched: act_pedit: really ensure the skb is writable
Currently pedit tries to ensure that the accessed skb offset
is writable via skb_unclone(). The action potentially allows
touching any skb bytes, so it may end-up modifying shared data.
The above causes some sporadic MPTCP self-test failures, due to
this code:
The above modifies a data byte outside the skb head and the skb is
a cloned one, carrying a TCP output packet.
This change addresses the issue by keeping track of a rough
over-estimate highest skb offset accessed by the action and ensuring
such offset is really writable.
Note that this may cause performance regressions in some scenarios,
but hopefully pedit is not in the critical path.

arm[64]/memremap: don't abuse pfn_valid() to ensure presence of linear map

Use the commonly accepted style to indicate to the compiler that we

for the fields we are initializing which makes the compiler happy.

fanotify: do not allow setting dirent events in mask of non-dir
Dirent events (create/delete/move) are only reported on watched
directory inodes, but in fanotify as well as in legacy inotify, it was
always allowed to set them on non-dir inode, which does not result in
any meaningful outcome.
Until kernel v5.17, dirent events in fanotify also differed from events
"on child" (e.g. FAN_OPEN) in the information provided in the event.
For example, FAN_OPEN could be set in the mask of a non-dir or the mask
of its parent and event would report the fid of the child regardless of
the marked object.
By contrast, FAN_DELETE is not reported if the child is marked and the
child fid was not reported in the events.
Since kernel v5.17, with fanotify group flag FAN_REPORT_TARGET_FID, the
fid of the child is reported with dirent events, like events "on child",
which may create confusion for users expecting the same behavior as
events "on child" when setting events in the mask on a child.
The desired semantics of setting dirent events in the mask of a child
are not clear, so for now, deny this action for a group initialized
with flag FAN_REPORT_TARGET_FID and for the new event FAN_RENAME.
We may relax this restriction in the future if we decide on the
semantics and implement them.

net: fix wrong network header length
When clatd starts with ebpf offloaing, and NETIF_F_GRO_FRAGLIST is enable,

network_header\transport_header\mac_header have been updated as ipv4 acts,
but other skbs in frag_list didnot update anything, just ipv6 packets.
udp_queue_rcv_skb will call skb_segment_list to traverse other skbs in
frag_list and make sure right udp payload is delivered to user space.
Unfortunately, other skbs in frag_list who are still ipv6 packets are
updated like the first skb and will have wrong transport header length.
e.g.before bpf_skb_proto_6_to_4,the first skb and other skbs in frag_list
has the same network_header(24)& transport_header(64), after
bpf_skb_proto_6_to_4, ipv6 protocol has been changed to ipv4, the first
skb's network_header is 44,transport_header is 64, other skbs in frag_list
didnot change.After skb_segment_list, the other skbs in frag_list has
different network_header(24) and transport_header(44), so there will be 20
bytes different from original,that is difference between ipv6 header and
ipv4 header. Just change transport_header to be the same with original.
Actually, there are two solutions to fix it, one is traversing all skbs
and changing every skb header in bpf_skb_proto_6_to_4, the other is
modifying frag_list skb's header in skb_segment_list. Considering
efficiency, adopt the second one--- when the first skb and other skbs in
frag_list has different network_header length, restore them to make sure
right udp payload is delivered to user space.

net: sfc: fix memory leak due to ptp channel
It fixes memory leak in ring buffer change logic.
When ring buffer size is changed(ethtool -G eth0 rx 4096), sfc driver
works like below.
1. stop all channels and remove ring buffers.
2. allocates new buffer array.
3. allocates rx buffers.
4. start channels.
While the above steps are working, it skips some steps if the channel
doesn't have a ->copy callback function.
Due to ptp channel doesn't have ->copy callback, these above steps are
skipped for ptp channel.
It eventually makes some problems.
a. ptp channel's ring buffer size is not changed, it works only
1024(default).
b. memory leak.
The reason for memory leak is to use the wrong ring buffer values.
There are some values, which is related to ring buffer size.
a. efx->rxq_entries
- This is global value of rx queue size.
b. rx_queue->ptr_mask
- used for access ring buffer as circular ring.
- roundup_pow_of_two(efx->rxq_entries) - 1
c. rx_queue->max_fill
- efx->rxq_entries - EFX_RXD_HEAD_ROOM
These all values should be based on ring buffer size consistently.
But ptp channel's values are not.
a. efx->rxq_entries
- This is global(for sfc) value, always new ring buffer size.
b. rx_queue->ptr_mask
- This is always 1023(default).
c. rx_queue->max_fill
- This is new ring buffer size - EFX_RXD_HEAD_ROOM.
sfc driver allocates rx ring buffers based on these values.
When it allocates ptp channel's ring buffer, 4086 ring buffers are
allocated then, these buffers are attached to the allocated array.
But ptp channel's ring buffer array size is still 1024(default)
and ptr_mask is still 1023 too.
So, 3062 ring buffers will be overwritten to the array.
This is the reason for memory leak.
Test commands:
ethtool -G <interface name> rx 4096
while :
do
ip link set <interface name> up
ip link set <interface name> down
done
In order to avoid this problem, it adds ->copy callback to ptp channel
type.
So that rx_queue->ptr_mask value will be updated correctly.

prevent that"
