When building SYN packet in tcp_syn_options(), MSS, TS, WS, and
SACKPERM are used without checking the remaining bytes in the
options area.
To keep that logic as is, we limit the TCP-AO MAC length in
tcp_ao_parse_crypto(). Currently, the limit is calculated as below.
MAX_TCP_OPTION_SPACE - TCPOLEN_TSTAMP_ALIGNED
- TCPOLEN_WSCALE_ALIGNED
- TCPOLEN_SACKPERM_ALIGNED
This looks confusing as (1) we pack SACKPERM into the leading
2-bytes of the aligned 12-bytes of TS and (2) TCPOLEN_MSS_ALIGNED
is not used. Fortunately, the calculated limit is not wrong as
TCPOLEN_SACKPERM_ALIGNED and TCPOLEN_MSS_ALIGNED are the same value.
However, we should use the proper constant in the formula.
MAX_TCP_OPTION_SPACE - TCPOLEN_MSS_ALIGNED
- TCPOLEN_TSTAMP_ALIGNED
- TCPOLEN_WSCALE_ALIGNED

What happens is that inside most classifiers the tcf_result is copied over
from a filter template e.g. *res = f->res which then implicitly overrides
the prior SKB_DROP_REASON_TC_{INGRESS,EGRESS} default drop code which was
set via sch_handle_{ingress,egress}() for kfree_skb_reason().

David Morley and Neal Cardwell started investigating and Neal pointed
that we had :
tcp_conn_request()
tcp_try_fastopen()
-> tcp_fastopen_create_child
-> child = inet_csk(sk)->icsk_af_ops->syn_recv_sock()
-> tcp_create_openreq_child()
-> copy req_usec_ts from req:
newtp->tcp_usec_ts = treq->req_usec_ts;
// now the new TFO server socket always does usec TS, no matter
// what the route options are...
send_synack()
-> tcp_make_synack()
// disable tcp_rsk(req)->req_usec_ts if route option is not present:
if (tcp_rsk(req)->req_usec_ts < 0)
tcp_rsk(req)->req_usec_ts = dst_tcp_usec_ts(dst);
tcp_conn_request() has the initial dst, we can initialize
tcp_rsk(req)->req_usec_ts there instead of later in send_synack();
This means tcp_rsk(req)->req_usec_ts can be a boolean.
Many thanks to David an Neal for their help.

The comment for idr_for_each_entry_ul() states
after normal termination @entry is left with the value NULL
This is not correct in the case where UINT_MAX has an entry in the idr.
In that case @entry will be non-NULL after termination.
No current code depends on the documentation being correct, but to
save future code we should fix it.
Also fix idr_for_each_entry_continue_ul(). While this is not documented
as leaving @entry as NULL, the mellanox driver appears to depend on
it doing so. So make that explicit in the documentation as well as in

However, SELinux/Smack started to read it in netlbl_req_setattr()

Commit 284904aa79 ("lsm: Relocate the IPv4 security_inet_conn_request()

TIPC bearer-related names including link names must be null-terminated
strings. If a link name which is not null-terminated is passed through
netlink, strstr() and similar functions can cause buffer overrun. This
causes the above issue.
This patch changes the nla_policy for bearer-related names from NLA_STRING
to NLA_NUL_STRING. This resolves the issue by ensuring that only
null-terminated strings are accepted as bearer-related names.
syzbot reported similar uninit-value issue related to bearer names [2]. The
root cause of this issue is that a non-null-terminated bearer name was

Add a mac_len test before all three eth_hdr(skb) calls under net/llc.
There are further uses in include/net/llc_pdu.h. All these are
protected by a test skb->protocol == ETH_P_802_2. Which does not
protect against this tun scenario.
But the mac_len test added in this patch in llc_fixup_skb will
indirectly protect those too. That is called from llc_rcv before any
other LLC code.
It is tempting to just add a blanket mac_len check in llc_rcv, but
not sure whether that could break valid LLC paths that do not assume
an Ethernet header. 802.2 LLC may be used on top of non-802.3
protocols in principle. The below referenced commit shows that used
to, on top of Token Ring.
At least one of the three eth_hdr uses goes back to before the start
of git history. But the one that syzbot exercises is introduced in
this commit. That commit is old enough (2008), that effectively all
stable kernels should receive this.
Fixes: f83f1768f8 ("[LLC]: skb allocation size for responses")

I often regenerate all YNL files in the tree to make sure they
are in sync with the codegen and specs. Generator rewrites
the files unconditionally, so since make looks at file modification
time to decide what to rebuild - my next build takes longer.
We already generate the code to a tempfile most of the time,
only overwrite the target when we have to.

objects from the pre-allocated object pool. Since the index of ring
array is a 32bit sequential counter, we can retry to push/pop the

The highlights for the driver support this time are
- Qualcomm platforms gain support for the Qualcomm Secure Execution
Environment firmware interface to access EFI variables on certain
devices, and new features for multiple platform and firmware drivers.
- Arm FF-A firmware support gains support for v1.1 specification features,
in particular notification and memory transaction descriptor changes.
- SCMI firmware support now support v3.2 features for clock and DVFS
configuration and a new transport for Qualcomm platforms.
- Minor cleanups and bugfixes are added to pretty much all the active
platforms: qualcomm, broadcom, dove, ti-k3, rockchip, sifive, amlogic,
atmel, tegra, aspeed, vexpress, mediatek, samsung and more.
In particular, this contains portions of the treewide conversion to
use __counted_by annotations and the device_get_match_data helper.

Pull SoC driver updates from Arnd Bergmann:
"The highlights for the driver support this time are
- Qualcomm platforms gain support for the Qualcomm Secure Execution
Environment firmware interface to access EFI variables on certain
devices, and new features for multiple platform and firmware
drivers.
- Arm FF-A firmware support gains support for v1.1 specification
features, in particular notification and memory transaction
descriptor changes.
- SCMI firmware support now support v3.2 features for clock and DVFS
configuration and a new transport for Qualcomm platforms.
- Minor cleanups and bugfixes are added to pretty much all the active
platforms: qualcomm, broadcom, dove, ti-k3, rockchip, sifive,
amlogic, atmel, tegra, aspeed, vexpress, mediatek, samsung and
more.
In particular, this contains portions of the treewide conversion to
use __counted_by annotations and the device_get_match_data helper"

There are a couple new SoCs that are supported for the first time:
- AMD Pensando Elba is a data processing unit based on Cortex-A72
CPU cores
- Sophgo makes RISC-V based chips, and we now support the CV1800B
chip used in the milkv-duo board and the massive sg2042 chip in the
milkv-pioneer, a 64-core developer workstation.
- Qualcomm Snapdragon 720G (sm7125) is a close relative of
Snapdragon 7c and gets added with some Xiaomi phones
- Renesas gains support for the R8A779F4 (R-Car S4-8) automotive
SoC and the RZ/G3S (R9A08G045) embedded SoC.
There are also a bunch of newly supported machines that use
already supported chips. On the 32-bit side, we have:
- USRobotics USR8200 is a NAS/Firewall/router based on the ancient
Intel IXP4xx platform
- A couple of machines based on the NXP i.MX5 and i.MX6 platforms
- One machine each for Allwinner V3s, Aspeed AST2600, Microchip
sama5d29 and ST STM32mp157
The other ones all use arm64 cores on chips from allwinner,
amlogic, freescale, mediatek, qualcomm and rockchip.

- Add support for "chunk mode" in the mlx5-vfio-pci variant driver,
which allows both larger device image sizes for migration, beyond
the previous 4GB limit, and also read-ahead support for improved
migration performance. (Yishai Hadas)
- A new bus master control interface for the CDX bus driver where
there is no in-band mechanism to toggle device DMA as there is
through config space on PCI devices. (Nipun Gupta)
- Add explicit alignment directives to vfio data structures to
reduce the chance of breaking 32-bit userspace. In most cases
this is transparent and the remaining cases where data structures
are padded work within the existing rules for extending data
structures within vfio. (Stefan Hajnoczi)
- Resolve a bug in the cdx bus driver noted when compiled with clang
where missing parenthesis result in the wrong operation.
(Nathan Chancellor)
- Resolve errors reported by smatch for a function when dealing
with invalid inputs. (Alex Williamson)
- Add migration support to the mtty vfio/mdev sample driver for
testing and integration purposes, allowing CI of migration without
specific hardware requirements. Also resolve many of the short-
comings of this driver relative to implementation of the vfio
interrupt ioctl along the way. (Alex Williamson)

- Update DM core to respect REQ_NOWAIT flag in normal bios so that
memory allocations are always attempted with GFP_NOWAIT.
- Add Mikulas Patocka to MAINTAINERS as a DM maintainer!
- Improve DM delay target's handling of short delays (< 50ms) by using
a kthread to check expiration of IOs rather than timers and a wq.
- Update the DM error target so that it works with zoned storage. This
helps xfstests to provide proper IO error handling coverage when
testing a filesystem with native zoned storage support.
- Update both DM crypt and integrity targets to improve performance by
using crypto_shash_digest() rather than init+update+final sequence.
- Fix DM crypt target by backfilling missing memory allocation
accounting for compound pages.
