Linus Torvalds	5b33fc6492	Merge tag 'sched_ext-for-7.2' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/sched_ext ... Pull sched_ext updates from Tejun Heo: "Most of this continues the in-development sub-scheduler support, which lets a root BPF scheduler delegate to nested sub-schedulers. The dispatch-path building blocks landed in 7.1. A follow-up patchset in development will complete enqueue-path support for hierarchical scheduling. This cycle adds most of that infrastructure: - Topological CPU IDs (cids): a dense, topology-ordered CPU numbering where the CPUs of a core, LLC, or NUMA node form contiguous ranges, so a topology unit becomes a (start, length) slice. Raw CPU numbers are sparse and don't track topological closeness, which makes them clumsy for sharding work across sub-schedulers and awkward in BPF. - cmask: bitmaps windowed over a slice of cid space, so a sub-scheduler can track, for example, the idle cids of its shard without a full NR_CPUS cpumask. - A struct_ops variant that cid-form sub-schedulers register with, along with the cid-form kfuncs they call. - BPF arena integration, which sub-scheduler support is built on. The bpf-next additions let the kernel read and write the BPF scheduler's arena directly, turning it into a real kernel/BPF shared-memory channel. Shared state like the per-CPU cmask now lives there. - scx_qmap is reworked to exercise the new arena and cid interfaces. Additionally: - Exit-dump improvements: dump the faulting CPU first, expose the exit CPU to BPF and userspace, and normalize the dump header. - Misc kfuncs and cleanups: a task-ID lookup kfunc, __printf checking on the error and dump formatters, header reorganization, and assorted fixes" * tag 'sched_ext-for-7.2' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/sched_ext: (59 commits) sched_ext: Add scx_arena_to_kaddr() / scx_kaddr_to_arena() sched_ext: Make scx_bpf_kick_cid() return s32 sched_ext: Add scx_cmask_test() and scx_cmask_for_each_cid() tools/sched_ext: Order single-cid cmask helpers as (cid, mask) sched_ext: Order single-cid cmask helpers as (cid, mask) selftests/sched_ext: Fix dsq_move_to_local check sched_ext: Guard BPF arena helper calls to fix 32-bit build sched_ext: idle: Fix errno loss in scx_idle_init() sched_ext: Convert ops.set_cmask() to arena-resident cmask sched_ext: Sub-allocator over kernel-claimed BPF arena pages sched_ext: Require an arena for cid-form schedulers sched_ext: Add cmask mask ops sched_ext: Track bits[] storage size in struct scx_cmask sched_ext: Rename scx_cmask.nr_bits to nr_cids tools/sched_ext: scx_qmap: Fix qa arena placement sched_ext: Mark !CONFIG_EXT_SUB_SCHED dummy stubs static inline sched_ext: Replace tryget_task_struct() with get_task_struct() sched_ext: Add scx_task_iter_relock() and use it in scx_root_enable_workfn() sched_ext: Fix ops_cid layout assert sched_ext: Use offsetofend on both sides of the ops_cid layout assert ...	2026-06-17 12:10:11 +01:00
Linus Torvalds	83476cc97b	Merge tag 'cgroup-for-7.2' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup ... Pull cgroup updates from Tejun Heo: - Last cycle deferred css teardown on cgroup removal until the cgroup depopulated, so a css is not taken offline while tasks can still reference it. Disabling a controller through cgroup.subtree_control still had the same problem. This reworks the deferral from per-cgroup to per-css so that path is covered too. - New RDMA controller monitoring files: rdma.peak for per-device peak usage and rdma.events / rdma.events.local for resource-limit exhaustion. The max-limit parser was rewritten, fixing two input parsing bugs. - cpuset: fix a sched-domain leak on the domain-rebuild failure path and skip a redundant hardwall ancestor scan on v2. - Misc: pair the remaining lockless cgroup.max.* reads with WRITE_ONCE, assorted selftest robustness fixes, and doc path corrections. * tag 'cgroup-for-7.2' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup: (22 commits) cgroup: Migrate tasks to the root css when a controller is rebound docs: cgroup: Fix stale source file paths cgroup/cpuset: Free sched domains on rebuild guard failure cgroup: pair max limit READ_ONCE() with WRITE_ONCE() selftests/cgroup: enable memory controller in hugetlb memcg test cgroup/rdma: Drop unnecessary READ_ONCE() on event counters cgroup: Defer kill_css_finish() in cgroup_apply_control_disable() cgroup: Add per-subsys-css kill_css_finish deferral cgroup: Move populated counters to cgroup_subsys_state cgroup: Annotate unlocked nr_populated_* accesses with READ_ONCE/WRITE_ONCE cgroup: Inline cgroup_has_tasks() in cgroup.h cgroup/rdma: document rdma.peak, rdma.events and rdma.events.local cgroup/rdma: add rdma.events.local for per-cgroup allocation failure attribution cgroup/rdma: add rdma.events to track resource limit exhaustion cgroup/rdma: add rdma.peak for per-device peak usage tracking selftests/cgroup: check malloc return value in alloc_anon functions cgroup/cpuset: Skip hardwall ancestor scan in cpuset v2 in cpuset_current_node_allowed() selftests/cgroup: fix misleading debug message in test_cgfreezer_time_child selftests/cgroup: fix child process escaping to parent cleanup in test_cpucg_nice selftests/cgroup: Add NULL check after malloc in cgroup_util.c ...	2026-06-17 12:03:56 +01:00
Linus Torvalds	9c87e61e3c	Merge tag 'bpf-next-7.2' of git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next ... Pull bpf updates from Alexei Starovoitov: "Major changes: - Recover from BPF arena page faults using a scratch page and add ptep_try_set() for lockless empty-slot installs on x86 and arm64. This allows BPF kfuncs to access arena pointers directly. The 'arena_direct_access' stable branch was created for this work and was pulled into sched-ext and bpf-next trees (Tejun Heo, Kumar Kartikeya Dwivedi) - Lift old restriction and support 6+ arguments in BPF programs and kfuncs on x86 and arm64 (Yonghong Song, Puranjay Mohan) Other features and fixes: - Add 24-bit BTF vlen and reclaim unused bits in the BTF UAPI to ease addition of new BTF kinds (Alan Maguire) - Raise the maximum BPF call chain depth from 8 to 16 frames (Alexei Starovoitov) - Refactor object relationship tracking in the verifier and fix a dynptr use-after-free bug (Amery Hung) - Harden the signed program loader and reject exclusive maps as inner maps (Daniel Borkmann) - Replace the verifier min/max bounds fields with a circular number (cnum) representation and improve 32->64 bit range refinements (Eduard Zingerman) - Introduce the arena library and runtime (libarena) with a buddy allocator, rbtree and SPMC queue data structures, ASAN support and a parallel test harness.

Linus Torvalds	b85966adbf	Merge tag 'net-next-7.2' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next ... Pull networking updates from Jakub Kicinski: "Core & protocols: - Work on removing rtnl_lock protection throughout the stack continues. In this chapter: - don't use rtnl_lock for IPv6 multicast routing configuration - don't take rtnl_lock in ethtool for modern drivers - prepare Qdisc dump callbacks for rtnl_lock removal - Support dumping just ifindex + name of all interfaces, under RCU. It's a common operation for Netlink CLI tools (when translating names to ifindexes) and previously required full rtnl_lock. - Support dumping qdiscs and page pools for a specific netdev. Even tho user space wants a dump of all netdevs, most of the time, the OOO programming model results in repeating the dump for each netdev. Which, in absence of a cache, leads to a O(n^2) behavior. - Flush nexthops once on multi-nexthop removal (e.g. when device goes down), another O(n^2) -> O(n) improvement. - Rehash locally generated traffic to a different nexthop on retransmit timeout. - Honor oif when choosing nexthop for locally generated IPv6 traffic. - Convert TCP Auth Option to crypto library, and drop non-RFC algos. - Increase subflow limits in MPTCP to 64 and endpoint limit to 256. - Support MPTCP signaling of IPv6 address + port (ADD_ADDR). We need to selectively skip reporting of the standard TCP Timestamp option, because they won't fit into the header space together (12 + 30 > 40). - Support using bridge neighbor suppression, Duplicate Address Detection, Gratuitous ARP and unsolicited NA forwarding - in EVPN deployments, e.g. VXLAN fabrics (IPv4 and IPv6). - Improve link state reporting for upper netdevs (e.g. macvlan) over tunnel devices (again, mostly for EVPN deployments). - Support binding GENEVE tunnels to a local address. - Speed up UDP tunnel destruction (remove one synchronize_rcu()). - Support exponential field encoding in multicast (IGMPv3 and MLDv2). - Support attaching PSP crypto offload to containers (veth, netkit). - Add a new IPSec Netlink message XFRM_MSG_MIGRATE_STATE that allows migrating individual IPsec SAs independently of their policies. The existing XFRM_MSG_MIGRATE is tightly coupled to policy+SA migration, lacks SPI for unique SA identification, and cannot express reqid changes or migrate Transport mode selectors. The new interface identifies the SA via SPI and mark, supports reqid changes, address family changes, encap removal, and uses an atomic create+install flow under x->lock to prevent SN/IV reuse during AEAD SA migration. - Implement GRO/GSO support for PPPoE. - Convert sockopt callbacks in a number of protocols to iov_iter. Cross-tree stuff: - Remove support for Crypto TFM cloning (unblocked after the TCP Auth Option rework). This feature regressed performance for all crypto API users, since it changed crypto transformation objects into reference-counted objects. - Add FCrypt-PCBC implementation to rxrpc and remove it from the global crypto API as obsolete and insecure. Wireless: - Major rework of station bandwidth handling, fixing issues with lower capability than AP. - Cleanups for EMLSR spec issues (drafts differed). - More Neighbor Awareness Networking (Wi-Fi Aware) work (multicast, schedule improvements, multi-station etc.) - Some Ultra High Reliability (UHR) / IEEE 802.11bn (D1.4) work (e.g. non-primary channel access, UHR DBE support). - Fine Timing Measurement ranging (i.e. distance measurement) APIs. Netfilter: - Use per-rule hash initval in nf_conncount. This avoids unnecessary lock contention with short keys (e.g. conntrack zones) in different namespaces. - Various safety improvements, both in packet parsing and object lifetimes. Notably add refcounts to conntrack timeout policy. Deletions: - Remove TLS + sockmap integration. TLS wants to pin user pages to avoid a copy, and sockmap wants to write to the input stream. More work on this integration is clearly needed, and we can't find any users (original author admitted that they never deployed it). - Remove support for TLS offload with TCP Offload Engine (the far more common opportunistic offload is retained). The locking looks unfixable (driver sleeps under TCP spin locks) and people from the vendor that added this are AWOL. - Remove more ATM code, trying to leave behind only what PPPoATM needs, AAL5 and br2684 with permanent circuits. - Remove AppleTalk. Let it join hamradio in our out of tree protocol graveyard, I mean, repository. - Disable 32-bit x_tables compatibility (32bit binaries on 64bit kernel) interface in user namespaces. To be deleted completely, soon. - Remove 5/10 MHz support from cfg80211/mac80211. Drivers: - Software: - Support DEVMEM/DMABUF Tx over NETMEM_TX_NO_DMA devices (netkit) - bonding: add knob to strictly follow 802.3ad for link state - New drivers: - Alibaba Elastic Ethernet Adaptor (cloud vNIC). - NXP NETC switch within i.MX94. - DPLL: - Add operational state to pins (implement in zl3073x). - Add generic DPLL type, for daisy-chaining DPLLs (implement in ice). - Ethernet high-speed NICs: - Huawei (hinic3): - enhance tc flow offload support with queue selection, tunnels - nVidia/Mellanox: - avoid over-copying payload to the skb's linear part (up to 60% win for LRO on slow CPUs like ARM64 V2) - expose more per-queue stats over the standard API - support additional, unprivileged PFs in the DPU configuration - support Socket Direct (multi-PF) with switchdev offloads - add a pool / frag allocator for DMA mapped buffers for control objects, save memory on systems with 64kB page size - take advantage of the ability to dynamically change RSS table size, even when table is configured by the user - increase the max RSS table size for even traffic distribution - Ethernet NICs: - Marvell/Aquantia: - AQC113 PTP support - Realtek USB (r8152): - support 10Gbit Link Speeds and Energy-Efficient Ethernet (EEE) - support firmware loaded (for RTL8157/RTL8159) - support for the RTL8159 - Intel (ixgbe): - support Energy-Efficient Ethernet (EEE) on E610 devices - Ethernet switches: - Airoha: - support multiple netdevs on a single GDM block / port - Marvell (mv88e6xxx): - support SERDES of mv88e6321 - Microchip (ksz8/9): - rework the driver callbacks to remove one indirection layer - Motorcomm (yt921x): - support port rate policing - support TBF qdisc offload - support ACL/flower offload - nVidia/Mellanox: - expose per-PG rx_discards - Realtek: - rtl8365mb: bridge offloading and VLAN support - Ethernet PHYs: - Airoha: - support Airoha AN8801R Gigabit PHYs. - Micrel: - implement 3 low-loss cable tunables - Realtek: - support MDI swapping for RTL8226-CG - support MDIO for RTL931x - Qualcomm: - at803x: Rx and Tx clock management for IPQ5018 PHY - Motorcomm: - support YT8522 100M RMII PHY - set drive strength in YT8531s RGMII - TI: - dp83822: add optional external PHY clock - Bluetooth: - hci_sync: add support for HCI_LE_Set_Host_Feature [v2] - SMP: use AES-CMAC library API - Intel: - support Product level reset - support smart trigger dump - Mediatek: - add event filter to filter specific event - Realtek: - fix RTL8761B/BU broken LE extended scan - WiFi: - Broadcom (b43): - new support for a 11n device - MediaTek (mt76): - support mt7927 - mt792x: broken usb transport detection - mt7921: regulatory improvements - Qualcomm (ath9k): - GPIO interface improvements - Qualcomm (ath12k): - WDS support - replace dynamic memory allocation in WMI Rx path - thermal throttling/cooling device support - 6 GHz incumbent interference detection - channel 177 in 5 GHz - Realtek (rt89): - RTL8922AU support - USB 3 mode switch for performance - better monitor radiotap support - RTL8922DE preparations" * tag 'net-next-7.2' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next: (1778 commits) ipv4: fib_rule: Move fib4_rules_exit() to ->exit(). net: serialize netif_running() check in enqueue_to_backlog() net: skmsg: preserve sg.copy across SG transforms appletalk: move the protocol out of tree appletalk: stop storing per-interface state in struct net_device selftests/bpf: test that TLS crypto is rejected on a sockmap socket selftests/bpf: drop the unused kTLS program from test_sockmap selftests/bpf: remove sockmap + ktls tests tls: remove dead sockmap (psock) handling from the SW path tls: reject the combination of TLS and sockmap atm: remove orphaned uAPI for deleted drivers, protocols and SVCs atm: remove unused ATM PHY operations atm: remove the unused pre_send and send_bh device operations atm: remove the unused change_qos device operation atm: remove SVC socket support and the signaling daemon interface atm: remove the local ATM (NSAP) address registry atm: remove dead SONET PHY ioctls atm: remove the unused send_oam / push_oam callbacks atm: remove AAL3/4 transport support net: dsa: sja1105: fix lastused timestamp in flower stats ...	2026-06-17 08:17:00 +01:00

Jakub Kicinski	6af8971d91	selftests/bpf: drop the unused kTLS program from test_sockmap ... With the sockmap + kTLS tests gone, the BPF-side support in test_sockmap is dead: the tls_sock_map map and bpf_prog3 (which redirected skbs into it) are no longer referenced. Remove them, along with the now-unused bpf_write_pass() helper. bpf_prog3 was progs[2], so renumber the progs[] users in test_sockmap.c: the sockops program drops to progs[2] and the sk_msg tx programs to progs[3..7].

Change the option to match both documentation and the other timerlat tool, rtla-timerlat-top. - Extend coverage of runtime tests Cover both top and hist tools in all applicable test cases, add tests for a few uncovered options, and extend checks for some existing tests. - Add unit tests for actions rtla's actions feature is implemented in its source file and contains non-trivial parsing logic. Cover it with unit tests. - Stop record trace on interrupt Fix a bug where an interval exists after receiving a signal in which the main instance is stopped but the record instance is not, leading to discrepancies in reported results and sometimes rtla hanging. - Restore continue flag in actions_perform() Fix a bug where rtla always continues tracing after hitting a threshold even if the continue action was triggered just once, and add tests verifying that the flag is reset properly. - Migrate command line interface to libsubcmd Replace rtla's argument parsing using getopt_long() with libsubcmd, used by perf and objtool, to reuse existing code and auto-generate better help messages.

Add test_iou_zcrx_large_buf, which runs iou-zcrx with rx_buf_len > page size (-x 2) through a netkit-leased RX queue. The netkit ifindex is opaque to io_uring, but rx_page_size is honoured by the leased physical qops via netif_mp_open_rxq()'s lease redirect.

Neil Spring	ae57a55332	selftests: net: add local ECMP rehash test ... Add ecmp_rehash.sh with nine scenarios verifying that TCP rehash selects a different local ECMP path for IPv6: - SYN retransmission (forward path blocked during setup) - SYN/ACK retransmission (reverse path blocked during setup) - Midstream RTO (forward path blocked on established connection) - Midstream ACK rehash (reverse path blocked on established connection) - PLB rehash (ECN-driven congestion on established connection) - Hash policy 1 negative test (rehash attempted but path unchanged) - No flowlabel leak (client mp_hash does not alter on-wire flowlabel) - Dst rebuild consistency (dst invalidation does not change path) - Syncookie server path consistency (SYN-ACK and post-cookie ACKs use the same ECMP path) The policy 1 test verifies that fib_multipath_hash_policy=1 computes a deterministic 5-tuple hash, so txhash re-rolls do not change the ECMP path while TcpTimeoutRehash still increments. The flowlabel leak test sets auto_flowlabels=0 on the client and installs tc filters on client egress that drop TCP packets with nonzero flowlabel, confirming that the client's fl6->mp_hash does not leak into the on-wire IPv6 flow label. The PLB test needs DCTCP, a restricted congestion control. Rather than relax the host-global tcp_allowed_congestion_control (no per-netns equivalent), it pins dctcp on the test routes via the congctl route attribute, confined to the test namespaces. The dst rebuild test streams data, invalidates the cached dst by adding and removing a dummy route (bumping the fib6_node sernum), and verifies that traffic stays on the same path. The sernum change causes ip6_dst_check() to fail on the next transmit, triggering a fresh route lookup via inet6_csk_route_socket(). ECMP_REBUILD_ROUNDS=10 repeats the check to reduce the probability of a buggy kernel passing by chance with 2-way ECMP. The syncookie server path consistency test verifies that the server's SYN-ACK and subsequent ACKs use the same ECMP path. With syncookies, the request socket is freed after the SYN-ACK, so cookie_tcp_reqsk_init() must derive the same txhash (from the cookie) that was used for the SYN-ACK's route lookup. The syncookie test forces tcp_syncookies=2; it skips when CONFIG_SYN_COOKIES is not available. selftests/net/config selects it (and CONFIG_TCP_CONG_DCTCP for the PLB test).

Pull locking updates from Ingo Molnar: "Futex updates: - Optimize futex hash bucket access patterns (Peter Zijlstra) - Large series to address the robust futex unlock race for real, by Thomas Gleixner: "The robust futex unlock mechanism is racy in respect to the clearing of the robust_list_head::list_op_pending pointer because unlock and clearing the pointer are not atomic. The race window is between the unlock and clearing the pending op pointer. If the task is forced to exit in this window, exit will access a potentially invalid pending op pointer when cleaning up the robust list. That happens if another task manages to unmap the object containing the lock before the cleanup, which results in an UAF. In the worst case this UAF can lead to memory corruption when unrelated content has been mapped to the same address by the time the access happens. User space can't solve this problem without help from the kernel. This series provides the kernel side infrastructure to help it along: 1) Combined unlock, pointer clearing, wake-up for the contended case 2) VDSO based unlock and pointer clearing helpers with a fix-up function in the kernel when user space was interrupted within the critical section. ... with help by André Almeida: - Add a note about robust list race condition (André Almeida) - Add self-tests for robust release operations (André Almeida) Context analysis updates: - Implement context analysis for 'struct rt_mutex'.

The recent hardening against time moving backward requires that the related members of struct clocksource have been initialized, otherwise it clamps the readout to 0, which makes time stand sill and causes boot delays. - Fix a more than twenty year old PID reference count leak in an error path of the POSIX CPU timer code. - The usual small fixes, improvements and cleanups all over the place" * tag 'timers-core-2026-06-13' of gitolite.kernel.org:pub/scm/linux/kernel/git/tip/tip: (31 commits) posix-cpu-timers: Fix pid refcount leak in do_cpu_nanosleep() error path time/jiffies: Register jiffies clocksource before usage timers/migration: Temporarily disable per capacity hierarchies timers/migration: Turn tmigr_hierarchy level_list into a flexible array timers/migration: Deactivate per-capacity hierarchies under nohz_full timers/migration: Fix hotplug migrator selection target on asymetric capacity machines ntsync: Honour caller's time namespace for absolute MONOTONIC timeouts time/namespace: Export init_time_ns and do_timens_ktime_to_host() timers/migration: Update stale @online doc to @available timers: Fix flseep() typo in kernel-doc comment hrtimer: Fix the bogus return type of __hrtimer_start_range_ns() hrtimer: Return ktime_t from hrtimer_get_next_event()/hrtimer_next_event_without() clocksource: Clean up clocksource_update_freq() functions alarmtimer: Remove stale return description from alarm_handle_timer() selftests/posix_timers: Use CLOCK_THREAD_CPUTIME_ID for ITIMER_PROF measurements scripts/timers: Add timer_migration_tree.py timers/migration: Handle capacity in connect tracepoints timers/migration: Split per-capacity hierarchies timers/migration: Track CPUs in a hierarchy timers/migration: Abstract out hierarchy to prepare for CPU capacity awareness ...	2026-06-15 13:39:12 +05:30

Alexei Starovoitov	e4287bf34f	selftests/bpf: Work around llvm stack overflow in crypto progs ... clang 23 fails to build crypto_bench.c and crypto_sanity.c with "BPF stack limit exceeded". The progs fill a 408-byte bpf_crypto_params on the stack and pass it to bpf_crypto_ctx_create(). clang 23 copies the byte-aligned cipher/key globals into it one byte at a time through the stack, and keeps more than one copy of the struct around. Together that blows the 512-byte limit. Align the source arrays to 8 bytes so the copy is word-wise, and move params off the stack into a static .bss var. static keeps it out of the skeleton, where bpf_crypto_params is an incomplete type. Either change alone is not enough. Signed-off-by: Alexei Starovoitov <ast@kernel.org>	2026-06-15 00:19:44 -07:00

Leo Yan	62617d28d9	selftests/bpf: Avoid static LLVM linking for cross builds ... The BPF selftests prefer static LLVM linking, which works for native builds but can break cross builds. Its --link-static output may include host-only libraries that are unavailable for the cross compilation, causing link failures. Avoid static LLVM linking for cross builds and use shared LLVM libraries instead. Native builds keep the existing behavior.

Leo Yan	584f3b7a35	selftests/bpf: Use common CFLAGS for urandom_read ... The urandom_read helper and its shared library are built with $(CLANG) directly rather than through the normal selftest $(CC) rules. The CFLAGS variable can contain specific flags only for $(CC) but might be imcompatible for $(CLANG) and those flags are not necessarily valid for the clang-only urandom_read build. Split the BPF selftest local flags into COMMON_CFLAGS and append them to CFLAGS for the normal build path. Use COMMON_CFLAGS directly for urandom_read and liburandom_read.so, while still filtering out -static as before.

Leo Yan	f3846b3800	libbpf: Initialize CFLAGS before including Makefile.include ... tools/scripts/Makefile.include may expand EXTRA_CFLAGS in a future change. This could alter the initialization of CFLAGS, as the default options "-g -O2" would never be set once EXTRA_CFLAGS is expanded. Prepare for this by moving the CFLAGS initialization before including tools/scripts/Makefile.include, so it is not affected by the extended EXTRA_CFLAGS. Append EXTRA_CFLAGS to CFLAGS only after including Makefile.include and place it last so that the extra flags propagate properly and can override the default options. tools/scripts/Makefile.include already appends $(CLANG_CROSS_FLAGS) to CFLAGS, the Makefile appends $(CLANG_CROSS_FLAGS) again, remove the redundant append.
