smb client fixes for v7.3-rc3
A batch of bug fixes for the smb client:
- File type corruption fixes in reparse point handling: setting S_IFMT
bits without clearing the existing type first corrupted the file mode
(e.g. S_IFREG | S_IFCHR == S_IFLNK). Fixed in the WSL, POSIX and
native symlink reparse parsers. Also fixes an uninitialized SID
structure in the POSIX readdir path when parsing fails.
- Ownership mapping fixes: forceuid/forcegid mount options were
ignored in several code paths (SID-to-id mapping, WSL extended
attributes, POSIX extensions getattr), allowing an untrusted server
to dictate local file ownership despite explicit mount overrides.
- Heap overflow and overflow fixes in DACL rewriting: replacing short
SIDs with long ones could overflow the DACL buffer, and the u16
accumulator for DACL size could wrap around with enough ACEs.
- Reference count leak fixes in oplock break and deferred close:
duplicate oplock breaks on a queued work item leaked a
cifsFileInfo reference, and deferred close had a similar leak when
requeueing a running work item. Both cause busy-inode oopses on
unmount.
- DFS superblock use-after-free fix: the iterator callback stored a
raw superblock pointer without pinning it, racing with automount
expiry.
- One-byte slab OOB read in the native symlink parser when handling
share-root relative paths.
- Hardening of legacy SMB1 input: reject userspace-crafted
cifs.idmap key descriptions that bypass kernel origin checks, and
validate DataOffset in CIFSSMBRead() to prevent heap info
disclosure from a malicious server.
- DFS cache fix: defer metadata updates until target copying
succeeds to prevent partial-state cache entries on allocation
failure.

sunvdc: unmap LDC cookies when the descriptor send fails
__send_request() maps the request's pages into the LDC channel's map table (ldc_map_sg()), fills in the descriptor and marks it VIO_DESC_READY before ringing the doorbell via __vdc_tx_trigger(). When the trigger fails, the error path only prints a message: the descriptor stays READY and the cookies are never unmapped. The mapping is normally released in vdc_end_one() when the peer completes the descriptor - but a descriptor whose doorbell was never sent will never complete, and since dr->prod is not advanced on failure, the reset path (vdc_requeue_inflight(), which walks [cons, prod)) never visits it either. The map table entries are leaked permanently. Since commit |

selftests: ublk: install test_common.sh and trace/ scripts
Every ublk test script sources test_common.sh from its own directory:
. "$(cd "$(dirname "$0")" && pwd)"/test_common.sh
and test_generic_02/12 additionally run bpftrace against the scripts in
trace/. Neither test_common.sh nor trace/ is listed in TEST_FILES, so
"make install" does not copy them into the install directory and every
ublk test fails when run from there:
./test_generic_02.sh: line 4: .../kselftest_install/ublk/test_common.sh: No such file or directory
./test_generic_02.sh: line 8: _have_program: command not found
The bpftrace tests are affected even when bpftrace is installed: the
missing trace/*.bt makes bpftrace exit immediately, and the tests then
report a skip rather than a failure, which hides the problem.
Add both to TEST_FILES, matching how other selftests ship their sourced
helpers (see kexec/kexec_common_lib.sh and zram/zram_lib.sh).

selftests: tc-testing: test action batch failure cleanup
Add tests for cleanup after a batched RTM_NEWACTION request fails. Replace an existing gact action bound to a filter, then fail a later entry by requesting goto chain without a classifier context. Check that the bound action's reference count returns to its original value. Also cover a successfully initialized new action between the bound action and the failing entry, verifying that its reserved index can be reused. Repeat the bound action in another batch to check that each temporary reference to the same action is released.

net/sched: act_api: release all action references on NEWACTION failure
When a batched RTM_NEWACTION request replaces an existing action,
tcf_idr_check_alloc() takes a temporary reference on it. If a later
action fails to initialize, tcf_action_destroy() uses strict release
semantics to clean up the actions initialized so far. For an action
bound to a filter, the strict check returns -EPERM without dropping
the temporary reference.
This error also makes tcf_action_destroy() return before releasing
subsequent entries. Any new action initialized between the bound
action and the failing entry is leaked together with its reserved
IDR slot, preventing reuse of its index.
Use tcf_idr_release() to drop each reference held by the batch without
rejecting bound actions. This allows cleanup to continue through all
initialized entries and preserves the module reference release when
an action is destroyed. Explicit action deletion and flushing retain
their separate bind-count checks.

ALSA: hdspm: Add a new PCI device ID (1d18:3fc6) for RME HDSPe AIO PCI express audio
The RME HDSPe AIO PCI express audio card has a new PCI vendor ID (1d18) while keeping the same device ID (3fc6). The card seems working fine by just adding the new ID. While we're at it, use the standard macro to cleann up the existing PCI ID entry, too.

openvswitch: fix wrong flag value in get_ipv6_ext_hdrs()
The ESP and AH cases in get_ipv6_ext_hdrs() used IPPROTO_FRAGMENT instead
of OFPIEH12_FRAG when checking for out-of-order extension headers, causing
the fragment header to not be recognised as a valid predecessor.
The original code used IPPROTO_FRAGMENT (44) as a bitmask constant where
OFPIEH12_FRAG (1 << 4 = 16) was intended. IPPROTO_FRAGMENT encodes bits
2, 3 and 5 (OFPIEH12_AUTH | OFPIEH12_DEST | OFPIEH12_ROUTER), but not
bit 4 (OFPIEH12_FRAG). This caused incorrect OFPIEH12_UNSEQ verdicts in
both the ESP and AH arms: the ESP arm failed to whitelist OFPIEH12_FRAG,
while the AH arm accidentally whitelisted OFPIEH12_AUTH.
With the fix, a packet with two AH headers now also gets OFPIEH12_UNSEQ
in addition to OFPIEH12_UNREP, matching the ESP arm which already sets
UNSEQ on a repeat, which is the intended behavior.

ipmr: account multicast table and route memory
A netadmin in a user+net namespace can create many IPv4 and IPv6 multicast routing tables with MRT_TABLE and MRT6_TABLE. Each unseen id allocates an mr_table via the shared mr_table_alloc(), links it into the per-net list, and leaves it until netns teardown. Those objects were not charged to memcg, so the host unreclaimable slab grows with the table count. Account mr_table allocations with GFP_KERNEL_ACCOUNT and mark the IPv4/IPv6 MFC caches SLAB_ACCOUNT. This matches the established handling of IP addresses, routes and alternate interface names. Unresolved MFC entries are still allocated from softIRQ with GFP_ATOMIC and are not charged. They expire after 10 seconds and are bounded by the socket receive queue; see commit |

net: phy: dp83td510: handle the active-high LED polarity mode
dp83td510_led_polarity_set() only recognizes PHY_LED_ACTIVE_LOW, so
PHY_LED_ACTIVE_HIGH falls through to the default case and returns -EINVAL.
of_phy_led() propagates the error, of_phy_leds() drops the LEDs registered
so far and passes it on, and phy_probe() returns it. A device tree marking
a DP83TD510 LED as 'active-high', which leds/common.yaml allows and
ethernet-phy.yaml references for led@N nodes, thus leaves the mdio device
unbound, so phy_attach_direct() falls back to the genphy driver, which
cannot drive this 10BASE-T1L single-mode PHY, so the interface has no
usable link.
The callback initializes polarity to DP83TD510E_LED_POLARITY(index), which
is the active-high setting, so the request is already satisfied and only
the case label is missing.

net: macb: initialize PTP state before registering clock
gem_ptp_init() registers the PTP clock before initializing
bp->tsu_clk_lock and the TSU hardware. Since ptp_clock_register()
publishes the PTP character device, userspace may invoke PTP callbacks
before the lock and hardware are ready.
In addition, gem_ptp_init() is called from both the interface open and
resume paths. Reinitializing tsu_clk_lock there can reset the lock while
timestamp processing is using it.
This race is theoretical and has not been observed in practice.
Initialize tsu_clk_lock once during probe and initialize the TSU before
registering the PTP clock.

hsr_portdev_setup() skips promiscuous mode on non-master ports when
hsr->fwd_offloaded is set. fwd_offloaded is derived only from the ring
slaves' NETIF_F_HW_HSR_FWD bit, so this also skips it for the interlink
port, which never gets forwarding offload. Without promiscuous mode,
the interlink NIC drops unicast frames addressed to hsr_dev's MAC

ipv6: fix fib6 walker UAF on seq stop
ipv6_route_iter_active() treats a walker in FWS_U at the table root as
already unlinked. fib6_del_route() can move a still-linked walker into
that same state when the current leaf is the last route at the root,
so ipv6_route_native_seq_stop() skips fib6_walker_unlink(). The seq
private object can then be freed while it remains on
net->ipv6.fib6_walkers. A later route deletion walks the dangling list
and uses the freed walker.
Use the list head as membership state and reinitialize it when
unlinking. Keep the existing w->node check so a never-started iterator
with a zeroed private object is not treated as linked.
The same stop helper is used by /proc/net/ipv6_route and by the BPF
ipv6_route iterator. The BPF show path only widens the race.

net: stmmac: fix TX descriptor availability check for TSO traffic
stmmac_tso_xmit() estimates the number of free TX descriptors required by
a TSO skb as:
(skb->len - proto_hdr_len) / TSO_MAX_BUFF_SIZE + 1
which assumes the payload is split into TSO_MAX_BUFF_SIZE chunks. This
underestimates the descriptors actually consumed by stmmac_tso_allocator(),
since each fragment is mapped individually and so it needs at least one
descriptor regardless of its size. Moreover, one descriptor is used for
the L2/L3/L4 headers and, when the MSS changes, one more is consumed for
the MSS context descriptor.
For a highly fragmented TSO skb the check can therefore pass even when the
ring has too few free slots. stmmac_tso_allocator() then writes past the
available descriptors, overwriting descriptors still owned by the DMA
engine, corrupting the TX ring.
Add stmmac_tso_get_num_desc() to compute the exact number of descriptors
needed for the header, the linear payload and each fragment, plus the MSS
context descriptor when required, and use it in the availability check.

net/rds: fix tcp stream corruption with large pages
rds_message_map_pages() assigns PAGE_SIZE bytes to every
scatterlist entry, even when total_len ends in a partial page. The RDS
congestion map is defined as 8192 bytes, so on systems with PAGE_SIZE
greater than 8192 the scatterlist maps bytes beyond the end of the
congestion map. RDS-TCP transmits the SG contents according to those
lengths, so the extra bytes become part of the TCP RDS stream and are
interpreted as subsequent RDS message headers, corrupting the stream.
Limit the final scatterlist mapping to the number of bytes remaining.
This has no effect on systems with a 4K page size and allows RDS-TCP to
be used on systems with 16K and larger page sizes.
The RDS selftest, which previously hung on 16K pages, now passes.

net: mana: restore the XDP program pointer when pre-allocation fails
mana_xdp_set() publishes the new program into apc->bpf_prog before it
allocates anything, because mana_pre_alloc_rxbufs() sizes the buffers
from it via mana_get_rxbuf_cfg(). When that allocation fails the
function returns the error directly, skipping the err_dealloc_rxbuffs
label which is the only place that restores the previous pointer.
The attach is reported as failed, so the BPF core drops the reference it
held for the caller and the program can be freed, while apc->bpf_prog
still points at it. The next consumer of mana_xdp_get() - typically
mana_chn_setxdp() from mana_alloc_queues() on the following ifup, or
after a TX timeout reset - then calls bpf_prog_add() on freed memory.
This is reachable from an ordinary "ip link set dev ethX xdp obj ..."
whenever the per-queue RX buffer pre-allocation cannot be satisfied.
Restore the previous program on that error path.

The MT7530 internal GE PHY advertises EEE by hardware default, but its EEE support is defective: with EEE advertised, some link partners fail to establish a stable link. On a 2-pair (4-wire) cable where both ends advertise gigabit, 1000BASE-T training cannot succeed, and instead of falling back to 100 Mbps the port loops, so no link or DHCP lease is ever obtained.

====================
net: restore EEE on MediaTek switches and SoC MACs
Both drivers fill in phylink_config.lpi_capabilities and
lpi_timer_default but never lpi_interfaces. phylink treats a MAC as
supporting managed EEE only when the tx_lpi methods are implemented and
BOTH bitmaps are non-empty, which phylink_create() decides once and for
all, so EEE has been off on every mt753x port and on every mtk_eth_soc
MAC that uses mtk_phylink_ops since the two commits named in the
Fixes: tags. Because the tx_lpi methods ARE implemented, phylink takes
the other branch and calls phy_disable_eee(), which fills
eee_disabled_modes - so userspace cannot enable EEE either.
On an MT7981B board with an MT7531 switch, before these patches:
== lan1
Cannot get EEE settings: Not supported
== lan2
Cannot get EEE settings: Not supported
== lan3
Cannot get EEE settings: Not supported
== lan4
Cannot get EEE settings: Not supported
== wan
Cannot get EEE settings: Not supported
lan1-3 are the MT7531 internal PHYs, lan4 is an EN8811H on switch port
5 whose MAC side runs 2500BASE-X rate matched to a 1 Gbps media link,
and wan is the mtk_eth_soc MAC with its directly attached 1 Gbps PHY -
so both drivers are covered.
Each patch fills lpi_interfaces from supported_interfaces and leaves
2.5 Gbps out of both bitmaps for now. LPI above 1 Gbps is unvalidated
rather than unsupported: both MACs fold 2.5 Gbps onto their 1 Gbps
speed encoding, so the 1 Gbps EEE force bit is what would govern it.
MediaTek's SDK driver sets the force bits for 100 Mbps and 1 Gbps only,
EEE signalling on 2500BASE-X is outside 802.3, and the 1 us unit of the
wakeup timers is undocumented at 2.5 times the port clock.
The SoC MAC patch fills lpi_interfaces only on SoCs carrying a new
MTK_GMAC_EEE capability. mtk_mac_enable_tx_lpi() programs wake-up times
taken from MT7531's reset values, and the capability marks the SoCs
where those have been measured to work: MT7981 for now. The others keep
today's behaviour, EEE unreachable from userspace, until someone with
the hardware confirms them.
Neither driver sets eee_enabled_default, so LPI stays off until
userspace asks for it with ethtool --set-eee. The EEE advertisement is
a different matter: phylink stops force-clearing it, so a PHY that
advertises EEE out of reset advertises it again and the link may
negotiate EEE, without this MAC asserting LPI. MT7531's internal PHYs
and EN7528 are the exceptions, for the reasons in patch 1. Devicetree
eee-broken-* marks act at the PHY level and keep working, so a board
that already distrusts its PHYs stays protected: OpenWrt marks all
modes broken on MT7621's internal PHYs.
The two patches are independent and touch different subsystems; they
are sent together because they are the same bug.
Targeted at net as a regression fix with an active userspace lockout;
can be retargeted at net-next if maintainers prefer.

net: ethernet: mtk_eth_soc: populate lpi_interfaces to fix EEE support
phylink_create() decides once and for all that a MAC supports managed
EEE, and it requires the tx_lpi ops plus non-empty lpi_capabilities and
lpi_interfaces. mtk_add_mac() leaves lpi_interfaces empty.
So ever since EEE support was added, ethtool has answered "Not
supported" on every MAC that uses mtk_phylink_ops, and
phy_disable_eee() has locked userspace out of turning EEE on. MT7628
is unaffected, as rt5350_phylink_ops has no tx_lpi methods.
Leave 2.5 Gbps out of both bitmaps, and the xGMII modes that
mtk_mac_enable_tx_lpi() already refuses. MAC_MCR folds SPEED_2500 onto
MAC_MCR_SPEED_1000, so MAC_MCR_EEE1G would govern LPI on such a link,
and that is unvalidated rather than known unsupported: MediaTek's SDK
driver sets the EEE force bits for 100 Mbps and 1 Gbps only, and the
unit of the wakeup timers is undocumented with the port clock at
2.5 times the rate.
mtk_mac_enable_tx_lpi() programs wake-up times taken from MT7531's
reset values, and the SoC's own field has no reset value to fall
back on. Only MT7981 has been seen to exit LPI cleanly with them, so
the LPI interfaces sit behind a new MTK_GMAC_EEE capability that only
MT7981 sets; every other SoC keeps the current behaviour until it has
been confirmed.
LPI stays off until userspace enables it, but the EEE advertisement of
a PHY that advertises it out of reset comes back, since phylink stops
force-clearing it.

net: hinic: fix mailbox segment buffer overflow
check_mbox_seq_id_and_seg_len() validates that seq_id does not
exceed SEQ_ID_MAX_VAL (42) and seg_len does not exceed
MBOX_SEG_LEN (48). However, this allows the last segment
(seq_id=42) to carry a full 48-byte payload, writing to offset
42*48=2016 for 48 bytes (ending at byte 2064). The receive
buffer is only MBOX_MAX_BUF_SZ (2048) bytes, resulting in a
16-byte heap buffer overflow.
The hinic3 driver already handles this correctly by defining
MBOX_LAST_SEG_MAX_LEN and rejecting the last segment when it
exceeds the remaining buffer space. Apply the same fix to the
hinic driver.

Merge branch 'net-sched-cls_route-fix-bucket-retention-and-handle-recomputation'
Victor Nogueira says: ==================== net/sched: cls_route: fix bucket retention and handle recomputation Patch 1 is the v1 patch, unchanged. route4_change() can move an existing filter to a different top-level bucket, since route4_set_parms() recomputes the handle from TCA_ROUTE4_TO/FROM/IIF. The filter is unlinked from the old bucket, but the bucket itself is never freed once it goes empty, so route4_delete() keeps reporting *last=false after the last live filter is gone. That pins the empty tcf_proto and leaks it. The filters linked to a bucket are refcounted now, and the bucket is dropped from head->table[] as soon as the count reaches zero. Reviewing v1, Sashiko pointed out that the duplicate scan in route4_set_parms() compares against the wrong handle [1]. Patches 2 and 3 fix the two symptoms of that. Patch 2 makes the scan compare against nhandle. f->handle is the handle the filter has before the update, not the one it is about to be linked under, so a change that moves a filter into a chain already holding nhandle misses the collision and links a second filter under the same handle. The newcomer is then unreachable: route4_get() returns the incumbent, and route4_classify() stops at the first filter whose f->id matches. Patch 3 handles the mirror case. An in-place replace computes an nhandle that the filter being replaced already carries, so the scan finds that filter and rejects the request with -EEXIST. The older filter is passed to route4_set_parms() and skipped in the scan. Skipping it alone would rename the filter it replaces: the 0x7F00 order bits are carried in no attribute and were folded into nhandle on the create path alone, so an order 1 filter came back as order 0, and a sibling sharing its key could then no longer be replaced at all. They are carried over now whenever the request builds the key the filter already has, which leaves a request that does change the key renaming the filter as before. Patch 4 adds tdc coverage for all three, including the cross-bucket move case Sashiko noted route.json had no test for.

net/sched: cls_route: Fix in-place replace
Building on the previous patch, route4_set_parms rejects a duplicate by
scanning the destination chain for nhandle, but the scan doesn't exclude
the older version it is replacing, so an in-place replace will match
the older version's handle and fail.
Fix this by passing the older filter as a parameter to route4_set_parms
(replacing "new") and skipping it in the scan.
Excluding the older version is not enough on its own. nhandle is built
out of TCA_ROUTE4_TO, TCA_ROUTE4_FROM and TCA_ROUTE4_IIF alone, while the
0x7F00 bits, which only tell apart filters sharing one key, are folded in
on the create path. Letting the replace through would therefore rename
the filter it replaces: replacing handle 0x10101 stored it back as
0x10001, and a sibling at 0x10201 could then no longer be replaced at
all, since its own nhandle collided with the renamed filter.
tc filter add ... handle 0x10101 route from 1 to 1 classid 1:1
tc filter add ... handle 0x10201 route from 1 to 1 classid 1:2
tc filter replace ... handle 0x10101 route from 1 to 1 classid 1:9
... fh 0x00010001 flowid 1:9 to 1 from 1
... fh 0x00010201 flowid 1:2 to 1 from 1
tc filter replace ... handle 0x10201 route from 1 to 1 classid 1:8
Error: Handle 10001 is already in use.
So carry those bits over when the key the request builds is the key the
older filter already has. An in-place replace then keeps the handle
userspace named the filter by, while a request that does change the key
still renames it, as it did before.
