Only print the warning message if you are writing to
"/proc/sys/kernel/unprivileged_bpf_disabled".
The kernel may print an annoying warning when you read
"/proc/sys/kernel/unprivileged_bpf_disabled" saying
WARNING: Unprivileged eBPF is enabled with eIBRS on, data leaks possible
via Spectre v2 BHB attacks!
However, this message is only meaningful when the feature is
disabled or enabled.

In one of our internal testing, we found a case where
- uapi struct bpf_tcp_sock is in vmlinux.h where vmlinux.h is not
generated from the testing kernel
- struct bpf_tcp_sock is not in vmlinux BTF
The above combination caused bpf load failure as the following
memory access
struct bpf_tcp_sock *tcp_sock = ...;
... tcp_sock->snd_cwnd ...
needs CORE relocation but the relocation cannot be resolved since
the kernel BTF does not have corresponding type.
Similar to other previous cases (nf_conn___init, tcp6_sock, mctcp_sock, etc.),
add the type to vmlinux BTF with BTF_EMIT_TYPE macro.

Stephen Veiss says:
====================
BPF selftests have ALLOWLIST and DENYLIST files, used to control which
tests are run in CI. These files are currently parsed by a shell
script. [1]
This patchset allows those files to be specified directly on the
test_progs command line (eg, as -a @ALLOWLIST).
This also fixes a bug in the existing test filter code causing
unnecessary duplicate top-level test filter entries to be created.

Improve test selection logic when using -a/-b/-d/-t options.
The list of tests to include or exclude can now be read from a file,
specified as @<filename>.
The file contains one name (or wildcard pattern) per line, and
comments beginning with # are ignored.
These options can be passed multiple times to read more than one file.

Split the logic to insert new tests into test filter sets out from

Fix the subtest insertion logic to reuse an existing top-level test

BTF_MEMBER_BITFIELD_SIZE
The btf_dump/struct_data selftest is failing with:
[...]
test_btf_dump_struct_data:FAIL:unexpected return value dumping fs_context unexpected unexpected return value dumping fs_context: actual -7 != expected 264
[...]
The reason is in btf_dump_type_data_check_overflow(). It does not use
BTF_MEMBER_BITFIELD_SIZE from the struct's member (btf_member). Instead,
it is using the enum size which is 4. It had been working till the recent
commit 4e04143c869c ("fs_context: drop the unused lsm_flags member")
removed an integer member which also removed the 4 bytes padding at the
end of the fs_context. Missing this 4 bytes padding exposed this bug. In
particular, when btf_dump_type_data_check_overflow() reaches the member
'phase', -E2BIG is returned.
The fix is to pass bit_sz to btf_dump_type_data_check_overflow(). In
btf_dump_type_data_check_overflow(), it does a different size check when
bit_sz is not zero.

latest clang
The selftest test_global_funcs/global_func1 failed with the latest clang17.
The reason is due to upstream ArgumentPromotionPass ([1]),
which may manipulate static function parameters and cause inlining
although the funciton is marked as noinline.
The original code:
static __attribute__ ((noinline))
int f0(int var, struct __sk_buff *skb)
{
return skb->len;
}
__attribute__ ((noinline))
int f1(struct __sk_buff *skb)
{
...
return f0(0, skb) + skb->len;
}
...
SEC("tc")
__failure __msg("combined stack size of 4 calls is 544")
int global_func1(struct __sk_buff *skb)
{
return f0(1, skb) + f1(skb) + f2(2, skb) + f3(3, skb, 4);
}
After ArgumentPromotionPass, the code is translated to
static __attribute__ ((noinline))
int f0(int var, int skb_len)
{
return skb_len;
}
__attribute__ ((noinline))
int f1(struct __sk_buff *skb)
{
...
return f0(0, skb->len) + skb->len;
}
...
SEC("tc")
__failure __msg("combined stack size of 4 calls is 544")
int global_func1(struct __sk_buff *skb)
{
return f0(1, skb->len) + f1(skb) + f2(2, skb) + f3(3, skb, 4);
}
And later llvm InstCombine phase recognized that f0()
simplify returns the value of the second argument and removed f0()
completely and the final code looks like:
__attribute__ ((noinline))
int f1(struct __sk_buff *skb)
{
...
return skb->len + skb->len;
}
...
SEC("tc")
__failure __msg("combined stack size of 4 calls is 544")
int global_func1(struct __sk_buff *skb)
{
return skb->len + f1(skb) + f2(2, skb) + f3(3, skb, 4);
}
If f0() is not inlined, the verification will fail with stack size
544 for a particular callchain. With f0() inlined, the maximum
stack size is 512 which is in the limit.
Let us add a `asm volatile ("")` in f0() to prevent ArgumentPromotionPass
from hoisting the code to its caller, and this fixed the test failure.

When using `bpftool map dump` with map_of_maps, it is usually
more convenient to show the inner map id instead of raw value.
We are changing the plain print behavior to show inner_map_id
instead of hex value, this would help with quick look up of
inner map with `bpftool map dump id <inner_map_id>`.
To avoid disrupting scripted behavior, we will add a new
`inner_map_id` field to json output instead of replacing value.
plain print:
```
$ bpftool map dump id 138

Now that ftrace supports direct call on arm64, BPF tracing programs work
on that architecture. This fixes the vast majority of BPF selftests
except for:
- multi_kprobe programs which require fprobe, not available on arm64 yet
- tracing_struct which requires trampoline support to access struct args
This patch updates the list of BPF selftests which are known to fail so
the BPF CI can validate the tests which pass now.

To correlate the hardware RX timestamp with something, add tracking of
two software timestamps both clock source CLOCK_TAI (see description in
man clock_gettime(2)).
XDP metadata is extended with xdp_timestamp for capturing when XDP
received the packet. Populated with BPF helper bpf_ktime_get_tai_ns(). I
could not find a BPF helper for getting CLOCK_REALTIME, which would have
been preferred. In userspace when AF_XDP sees the packet another
software timestamp is recorded via clock_gettime() also clock source
CLOCK_TAI.
Example output shortly after loading igc driver:
poll: 1 (0) skip=1 fail=0 redir=2
xsk_ring_cons__peek: 1
0x12557a8: rx_desc[1]->addr=100000000009000 addr=9100 comp_addr=9000
rx_hash: 0x82A96531 with RSS type:0x1
rx_timestamp: 1681740540304898909 (sec:1681740540.3049)
XDP RX-time: 1681740577304958316 (sec:1681740577.3050) delta sec:37.0001 (37000059.407 usec)
AF_XDP time: 1681740577305051315 (sec:1681740577.3051) delta sec:0.0001 (92.999 usec)
0x12557a8: complete idx=9 addr=9000
The first observation is that the 37 sec difference between RX HW vs XDP
timestamps, which indicate hardware is likely clock source
CLOCK_REALTIME, because (as of this writing) CLOCK_TAI is initialised
with a 37 sec offset.
The 93 usec (microsec) difference between XDP vs AF_XDP userspace is the
userspace wakeup time. On this hardware it was caused by CPU idle sleep
states, which can be reduced by tuning /dev/cpu_dma_latency.
View current requested/allowed latency bound via:
hexdump --format '"%d\n"' /dev/cpu_dma_latency
More explanation of the output and how this can be used to identify
clock drift for the HW clock can be seen here[1]:

The NIC hardware RX timestamping mechanism adds an optional tailored
header before the MAC header containing packet reception time. Optional
depending on RX descriptor TSIP status bit (IGC_RXDADV_STAT_TSIP). In
case this bit is set driver does offset adjustments to packet data start
and extracts the timestamp.
The timestamp need to be extracted before invoking the XDP bpf_prog,
because this area just before the packet is also accessible by XDP via
data_meta context pointer (and helper bpf_xdp_adjust_meta). Thus, an XDP
bpf_prog can potentially overwrite this and corrupt data that we want to
extract with the new kfunc for reading the timestamp.

This implements XDP hints kfunc for RX-hash (xmo_rx_hash).
The HW rss hash type is handled via mapping table.
This igc driver (default config) does L3 hashing for UDP packets
(excludes UDP src/dest ports in hash calc). Meaning RSS hash type is
L3 based. Tested that the igc_rss_type_num for UDP is either
IGC_RSS_TYPE_HASH_IPV4 or IGC_RSS_TYPE_HASH_IPV6.
This patch also updates AF_XDP zero-copy function igc_clean_rx_irq_zc()
to use the xdp_buff wrapper struct igc_xdp_buff.

Driver specific metadata data for XDP-hints kfuncs are propagated via tail
extending the struct xdp_buff with a locally scoped driver struct.
Zero-Copy AF_XDP/XSK does similar tricks via struct xdp_buff_xsk. This
xdp_buff_xsk struct contains a CB area (24 bytes) that can be used for
extending the locally scoped driver into. The XSK_CHECK_PRIV_TYPE define
catch size violations build time.
The changes needed for AF_XDP zero-copy in igc_clean_rx_irq_zc()
is done in next patch, because the member rx_desc isn't available
at this point.

When function igc_rx_hash() was introduced in v4.20 via commit 0507ef8a0372
("igc: Add transmit and receive fastpath and interrupt handlers"), the
hardware wasn't configured to provide RSS hash, thus it made sense to not
enable net_device NETIF_F_RXHASH feature bit.
The NIC hardware was configured to enable RSS hash info in v5.2 via commit
2121c2712f82 ("igc: Add multiple receive queues control supporting"), but
forgot to set the NETIF_F_RXHASH feature bit.
The original implementation of igc_rx_hash() didn't extract the associated
pkt_hash_type, but statically set PKT_HASH_TYPE_L3. The largest portions of
this patch are about extracting the RSS Type from the hardware and mapping
this to enum pkt_hash_types. This was based on Foxville i225 software user
manual rev-1.3.1 and tested on Intel Ethernet Controller I225-LM (rev 03).
For UDP it's worth noting that RSS (type) hashing have been disabled both for
IPv4 and IPv6 (see IGC_MRQC_RSS_FIELD_IPV4_UDP + IGC_MRQC_RSS_FIELD_IPV6_UDP)
because hardware RSS doesn't handle fragmented pkts well when enabled (can
cause out-of-order). This results in PKT_HASH_TYPE_L3 for UDP packets, and
hash value doesn't include UDP port numbers. Not being PKT_HASH_TYPE_L4, have
the effect that netstack will do a software based hash calc calling into
flow_dissect, but only when code calls skb_get_hash(), which doesn't
necessary happen for local delivery.
For QA verification testing I wrote a small bpftrace prog:

A new link type, BPF_LINK_TYPE_STRUCT_OPS, was added to attach
struct_ops to links. (226bc6ae6405) It would be helpful for users to
know which map is associated with the link.
The assumption was that every link is associated with a BPF program, but
this does not hold true for struct_ops. It would be better to display
map_id instead of prog_id for struct_ops links. However, some tools may
rely on the old assumption and need a prog_id. The discussion on the
mailing list suggests that tools should parse JSON format. We will maintain
the existing JSON format by adding a map_id without removing prog_id. As
for plain text format, we will remove prog_id from the header line and add
a map_id for struct_ops links.

Extend the bpf hashmap docs to include a brief description of the
internals of the LRU map type (setting appropriate API expectations),
including the original commit message from Martin and a variant on the
graph that I had presented during my Linux Plumbers Conference 2022
talk on "Pressure feedback for LRU map types"[0].
The node names in the dot file correspond roughly to the functions
where the logic for those decisions or steps is defined, to help
curious developers to cross-reference and update this logic if the
details of the LRU implementation ever differ from this description.

The cloned dynptr will point to the same data as its parent dynptr,
with the same type, offset, size and read-only properties.
Any writes to a dynptr will be reflected across all instances
(by 'instance', this means any dynptrs that point to the same
underlying data).
Please note that data slice and dynptr invalidations will affect all
instances as well. For example, if bpf_dynptr_write() is called on an
skb-type dynptr, all data slices of dynptr instances to that skb
will be invalidated as well (eg data slices of any clones, parents,
grandparents, ...). Another example is if a ringbuf dynptr is submitted,
any instance of that dynptr will be invalidated.
Changing the view of the dynptr (eg advancing the offset or
trimming the size) will only affect that dynptr and not affect any
other instances.
One example use case where cloning may be helpful is for hashing or
iterating through dynptr data. Cloning will allow the user to maintain
the original view of the dynptr for future use, while also allowing
views to smaller subsets of the data after the offset is advanced or the
size is trimmed.

bpf_dynptr_is_null returns true if the dynptr is null / invalid
(determined by whether ptr->data is NULL), else false if
the dynptr is a valid dynptr.
bpf_dynptr_is_rdonly returns true if the dynptr is read-only,
else false if the dynptr is read-writable. If the dynptr is
null / invalid, false is returned by default.

Add a new kfunc
int bpf_dynptr_adjust(struct bpf_dynptr_kern *ptr, u32 start, u32 end);
which adjusts the dynptr to reflect the new [start, end) interval.
In particular, it advances the offset of the dynptr by "start" bytes,
and if end is less than the size of the dynptr, then this will trim the
dynptr accordingly.
Adjusting the dynptr interval may be useful in certain situations.
For example, when hashing which takes in generic dynptrs, if the dynptr
points to a struct but only a certain memory region inside the struct
should be hashed, adjust can be used to narrow in on the
specific region to hash.

Pull networking updates from Paolo Abeni:
"Core:
- Introduce a config option to tweak MAX_SKB_FRAGS. Increasing the
default value allows for better BIG TCP performances
- Reduce compound page head access for zero-copy data transfers
- RPS/RFS improvements, avoiding unneeded NET_RX_SOFTIRQ when
possible
- Threaded NAPI improvements, adding defer skb free support and
unneeded softirq avoidance
- Address dst_entry reference count scalability issues, via false
sharing avoidance and optimize refcount tracking
- Add lockless accesses annotation to sk_err[_soft]
- Optimize again the skb struct layout
- Extends the skb drop reasons to make it usable by multiple
subsystems
- Better const qualifier awareness for socket casts
BPF:
- Add skb and XDP typed dynptrs which allow BPF programs for more
ergonomic and less brittle iteration through data and
variable-sized accesses
- Add a new BPF netfilter program type and minimal support to hook
BPF programs to netfilter hooks such as prerouting or forward
- Add more precise memory usage reporting for all BPF map types
- Adds support for using {FOU,GUE} encap with an ipip device
operating in collect_md mode and add a set of BPF kfuncs for
controlling encap params
- Allow BPF programs to detect at load time whether a particular
kfunc exists or not, and also add support for this in light
skeleton
- Bigger batch of BPF verifier improvements to prepare for upcoming
BPF open-coded iterators allowing for less restrictive looping
capabilities
- Rework RCU enforcement in the verifier, add kptr_rcu and enforce
BPF programs to NULL-check before passing such pointers into kfunc
- Add support for kptrs in percpu hashmaps, percpu LRU hashmaps and
in local storage maps
- Enable RCU semantics for task BPF kptrs and allow referenced kptr
tasks to be stored in BPF maps
- Add support for refcounted local kptrs to the verifier for allowing
shared ownership, useful for adding a node to both the BPF list and
rbtree
- Add BPF verifier support for ST instructions in
convert_ctx_access() which will help new -mcpu=v4 clang flag to
start emitting them
- Add ARM32 USDT support to libbpf
- Improve bpftool's visual program dump which produces the control
flow graph in a DOT format by adding C source inline annotations
Protocols:
- IPv4: Allow adding to IPv4 address a 'protocol' tag. Such value
indicates the provenance of the IP address
- IPv6: optimize route lookup, dropping unneeded R/W lock acquisition
- Add the handshake upcall mechanism, allowing the user-space to
implement generic TLS handshake on kernel's behalf
- Bridge: support per-{Port, VLAN} neighbor suppression, increasing
resilience to nodes failures
- SCTP: add support for Fair Capacity and Weighted Fair Queueing
schedulers
- MPTCP: delay first subflow allocation up to its first usage. This
will allow for later better LSM interaction
- xfrm: Remove inner/outer modes from input/output path. These are
not needed anymore
- WiFi:
- reduced neighbor report (RNR) handling for AP mode
- HW timestamping support
- support for randomized auth/deauth TA for PASN privacy
- per-link debugfs for multi-link
- TC offload support for mac80211 drivers
- mac80211 mesh fast-xmit and fast-rx support
- enable Wi-Fi 7 (EHT) mesh support
Netfilter:
- Add nf_tables 'brouting' support, to force a packet to be routed
instead of being bridged
- Update bridge netfilter and ovs conntrack helpers to handle IPv6
Jumbo packets properly, i.e. fetch the packet length from
hop-by-hop extension header. This is needed for BIT TCP support
- The iptables 32bit compat interface isn't compiled in by default
anymore
- Move ip(6)tables builtin icmp matches to the udptcp one. This has
the advantage that icmp/icmpv6 match doesn't load the
iptables/ip6tables modules anymore when iptables-nft is used
- Extended netlink error report for netdevice in flowtables and
netdev/chains. Allow for incrementally add/delete devices to netdev
basechain. Allow to create netdev chain without device
Driver API:
- Remove redundant Device Control Error Reporting Enable, as PCI core
has already error reporting enabled at enumeration time
- Move Multicast DB netlink handlers to core, allowing devices other
then bridge to use them
- Allow the page_pool to directly recycle the pages from safely
localized NAPI
- Implement lockless TX queue stop/wake combo macros, allowing for
further code de-duplication and sanitization
- Add YNL support for user headers and struct attrs
- Add partial YNL specification for devlink
- Add partial YNL specification for ethtool
- Add tc-mqprio and tc-taprio support for preemptible traffic classes
- Add tx push buf len param to ethtool, specifies the maximum number
of bytes of a transmitted packet a driver can push directly to the
underlying device
- Add basic LED support for switch/phy
- Add NAPI documentation, stop relaying on external links
- Convert dsa_master_ioctl() to netdev notifier. This is a
preparatory work to make the hardware timestamping layer selectable
by user space
- Add transceiver support and improve the error messages for CAN-FD
controllers

git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm
Pull device mapper updates from Mike Snitzer:
- Split dm-bufio's rw_semaphore and rbtree. Offers improvements to
dm-bufio's locking to allow increased concurrent IO -- particularly
for read access for buffers already in dm-bufio's cache.
- Also split dm-bio-prison-v1's spinlock and rbtree with comparable aim
at improving concurrent IO (for the DM thinp target).
- Both the dm-bufio and dm-bio-prison-v1 scaling of the number of locks
and rbtrees used are managed by dm_num_hash_locks(). And the hash
function used by both is dm_hash_locks_index().
- Allow DM targets to require DISCARD, WRITE_ZEROES and SECURE_ERASE to
be split at the target specified boundary (in terms of
max_discard_sectors, max_write_zeroes_sectors and
max_secure_erase_sectors respectively).
- DM verity error handling fix for check_at_most_once on FEC.
- Update DM verity target to emit audit events on verification failure
and more.
- DM core ->io_hints improvements needed in support of new discard
support that is added to the DM "zero" and "error" targets.
- Fix missing kmem_cache_destroy() call in initialization error path of
both the DM integrity and DM clone targets.
- A couple fixes for DM flakey, also add "error_reads" feature.
- Fix DM core's resume to not lock FS when the DM map is NULL;
otherwise initial table load can race with FS mount that takes
superblock's ->s_umount rw_semaphore.
- Various small improvements to both DM core and DM targets.

Pull io_uring updates from Jens Axboe:
- Cleanup of the io-wq per-node mapping, notably getting rid of it so
we just have a single io_wq entry per ring (Breno)
- Followup to the above, move accounting to io_wq as well and
completely drop struct io_wqe (Gabriel)
- Enable KASAN for the internal io_uring caches (Breno)
- Add support for multishot timeouts. Some applications use timeouts to
wake someone waiting on completion entries, and this makes it a bit
easier to just have a recurring timer rather than needing to rearm it
every time (David)
- Support archs that have shared cache coloring between userspace and
the kernel, and hence have strict address requirements for mmap'ing
the ring into userspace. This should only be parisc/hppa. (Helge, me)
- XFS has supported O_DIRECT writes without needing to lock the inode
exclusively for a long time, and ext4 now supports it as well. This
is true for the common cases of not extending the file size. Flag the
fs as having that feature, and utilize that to avoid serializing
those writes in io_uring (me)
- Enable completion batching for uring commands (me)
- Revert patch adding io_uring restriction to what can be GUP mapped or
not. This does not belong in io_uring, as io_uring isn't really
special in this regard. Since this is also getting in the way of
cleanups and improvements to the GUP code, get rid of if (me)
- A few series greatly reducing the complexity of registered resources,
like buffers or files. Not only does this clean up the code a lot,
the simplified code is also a LOT more efficient (Pavel)

it (Pavel)

Pull btrfs updates from David Sterba:
"Mostly core changes and cleanups, some notable fixes and two
performance improvements in directory logging.
The IO path cleanups are removing or refactoring old code, scrub main
loop has been completely rewritten also refactoring old code.
There are some changes to non-btrfs code, mostly trivial, the cgroup
punt bio logic is only moved from generic code.
Performance improvements:
- improve logging changes in a directory during one transaction,
avoid iterating over items and reduce lock contention (fsync time
4x lower)
- when logging directory entries during one transaction, reduce
locking of subvolume trees by checking tree-log instead
(improvement in throughput and latency for concurrent access to a
subvolume)
Notable fixes:
- dev-replace:
- properly honor read mode when requested to avoid reading from
source device
- target device won't be used for eventual read repair, this is
unreliable for NODATASUM files
- when there are unpaired (and unrepairable) metadata during
replace, exit early with error and don't try to finish whole
operation
- scrub ioctl properly rejects unknown flags
- fix global block reserve calculations
- fix partial direct io write when there's a page fault in the
middle, iomap will try to continue with partial request but the
btrfs part did not match that, this can lead to zeros written
instead of data
Core changes:
- io path:
- continued cleanups and refactoring around bio handling
- extent io submit path simplifications and cleanups
- flush write path simplifications and cleanups
- rework logic of passing sync mode of bio, with further cleanups
- rewrite scrub code flow, restructure how the stripes are enumerated
and verified in a more unified way
- allow to set lower threshold for block group reclaim in debug mode
to aid zoned mode testing
- remove obsolete time-based delayed ref throttling logic when
truncating items
- DREW locks are not using percpu variables anymore
- more warning fixes (-Wmaybe-uninitialized)
- u64 division simplifications
- error handling improvements
Non-btrfs code changes:
- push cgroup punt bio logic to btrfs code (there was no other user
of that), the functionality can be now selected separately by
BLK_CGROUP_PUNT_BIO
- crc32c_impl removed after removing last uses in btrfs code
- add btrfs_assertfail() to objtool table"
* tag 'for-6.4-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux: (147 commits)

commit 4bb7aac70b5d ("net: phy: fix circular LEDS_CLASS dependencies")
solved a build failure, but introduces a new config knob with a default
'y' value: PHYLIB_LEDS.
The latter is against the current new config policy. The exception
was raised to allow the user to catch bad configurations without led
support.
Anyway the current definition of PHYLIB_LEDS does not fit the above
goal: if LEDS_CLASS is disabled, the new config will be available
only with PHYLIB disabled, too.
Hide the mentioned config, to preserve the randconfig testing done so
far, while respecting the mentioned policy.

Pull remoteproc updates from Bjorn Andersson:
- Unnecessary type casts from the 'void *' rproc->priv pointer are
dropped throughout the subsystem.
- A kernel-doc error is corrected in the Mediatek SCPI IPI
implementation
- The firmware loading onto the IMX DSP remote processors is reworked
to avoid non-32bit memory operations. A module parameter is
introduced to assist development of firmware without communication
abilities in place. Error paths in imx_dsp_rproc_mbox_alloc() is
cleaned up
- The cluster configuration handling in the TI K3 R5 driver is
corrected and support for the single-R5 core found in the TI AM62x
SoC family is introduced
- The TI PRU driver device- to virtual-address translation is updated
to avoid compiler warning about the unsigned device-address always
being larger than 0
- The ST remoteproc driver is transitioned to use of_property_present()
- Issues with kicks arriving after the STM32 remote processor has been
shut down are mitigated by checking the processor's state before
handling them.
- Support for mailbox channels for communication with the remote
processors are added to the Xilinx R5 remoteproc driver. The naming
of carveouts are corrected and their parsing is reworked. For this a
couple of fixes targeting the mailbox subsystem are picked up here as
well.
- Reference counting of of_nodes are corrected in the ST, STM32, RCAR
and IMX remoteproc drivers

Pull rpmsg updates from Bjorn Andersson:
"The remove functions of the Qualcomm SMD and GLINK RPM platform
drivers are transitioned to the new void returning prototype. Likewise
is qcom_smd_unregister_edge() transitioned to void, as it
unconditionally returned 0.
An assumption about the ordering of the intent request acknowledgement
and advertisement of a new intent in the GLINK implementation is
corrected. Faulty error handling is corrected is improved in the TX
path, and duplicated code, in the same path, is cleaned up"
