2024-12-31ALSA: seq: Check UMP support for midi_version changeTakashi Iwai
When the kernel is built without UMP support but a user-space app requires the midi_version > 0, the kernel should return an error. Otherwise user-space assumes as if it were possible to deal, eventually hitting serious errors later.

2024-12-31RDMA/bnxt_re: Fix error recovery sequenceKalesh AP
Fixed to return ENXIO from __send_message_basic_sanity() to indicate that device is in error state. In the case of ERR_DEVICE_DETACHED state, the driver should not post the commands to the firmware as it will time out eventually. Removed bnxt_re_modify_qp() call from bnxt_re_dev_stop() as it is a no-op.

2024-12-31tracing: Have process_string() also allow arraysSteven Rostedt
In order to catch a common bug where a TRACE_EVENT() TP_fast_assign() assigns an address of an allocated string to the ring buffer and then references it in TP_printk(), which can be executed hours later when the string is free, the function test_event_printk() runs on all events as they are registered to make sure there's no unwanted dereferencing. It calls process_string() to handle cases in TP_printk() format that has "%s". It returns whether or not the string is safe. But it can have some false positives. For instance, xe_bo_move() has: TP_printk("move_lacks_source:%s, migrate object %p [size %zu] from %s to %s device_id:%s", __entry->move_lacks_source ? "yes" : "no", __entry->bo, __entry->size, xe_mem_type_to_name[__entry->old_placement], xe_mem_type_to_name[__entry->new_placement], __get_str(device_id)) Where the "%s" references into xe_mem_type_to_name[]. This is an array of pointers that should be safe for the event to access. Instead of flagging this as a bad reference, if a reference points to an array, where the record field is the index, consider it safe.

The root cause is a buggy MPTCP option len computation in some circumstances: the ADD_ADDR option should be mutually exclusive with DSS since the blamed commit. Still, mptcp_established_options_add_addr() tries to set the relevant info in mptcp_out_options, if the remaining space is large enough even when DSS is present. Since the ADD_ADDR infos and the DSS share the same union fields, adding first corrupts the latter. In the worst-case scenario, such corruption increases the DSS binary layout, exceeding the computed length and possibly overwriting the skb shared info. Address the issue by enforcing mutual exclusion in mptcp_established_options_add_addr(), too.

2024-12-30gve: trigger RX NAPI instead of TX NAPI in gve_xsk_wakeupJoshua Washington
Commit ba0925c34e0f ("gve: process XSK TX descriptors as part of RX NAPI") moved XSK TX processing to be part of the RX NAPI. However, that commit did not include triggering the RX NAPI in gve_xsk_wakeup. This is necessary because the TX NAPI only processes TX completions, meaning that a TX wakeup would not actually trigger XSK descriptor processing. Also, the branch on XDP_WAKEUP_TX was supposed to have been removed, as the NAPI should be scheduled whether the wakeup is for RX or TX.

2024-12-30Revert "ALSA: ump: Don't enumeration invalid groups for legacy rawmidi"Takashi Iwai
This reverts commit c2d188e137e77294323132a760a4608321a36a70. Although it's fine to filter the invalid UMP groups at the first probe time, this will become a problem when UMP groups are updated and (re-)activated. Then there is no way to re-add the substreams properly for the legacy rawmidi, and the new active groups will be still invisible. So let's revert the change. This will move back to showing the full 16 groups, but it's better than forever lost. Link: https://patch.msgid.link/20241230114023.3787-1-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>

The HP OMEN 8 (2022), corresponding to a board ID of 8A15, supports OMEN thermal profile and requires the timed profile quirk. Upon adding this ID to both the omen_thermal_profile_boards and omen_timed_thermal_profile_boards, significant bump in performance can be observed. For instance, SilverBench (https://silver.urih.com/) results improved from ~56,000 to ~69,000, as a result of higher power draws (and thus core frequencies) whilst under load: Package Power: - Before the patch: ~65W (dropping to about 55W under sustained load). - After the patch: ~115W (dropping to about 105W under sustained load). Core Power: - Before: ~60W (ditto above). - After: ~108W (ditto above). Add 8A15 to omen_thermal_profile_boards and omen_timed_thermal_profile_boards to improve performance.

2024-12-29virt: tdx-guest: Just leak decrypted memory on unrecoverable errorsLi RongQing
In CoCo VMs it is possible for the untrusted host to cause set_memory_decrypted() to fail such that an error is returned and the resulting memory is shared. Callers need to take care to handle these errors to avoid returning decrypted (shared) memory to the page allocator, which could lead to functional or security issues. Leak the decrypted memory when set_memory_decrypted() fails, and don't need to print an error since set_memory_decrypted() will call WARN_ONCE().

2024-12-29x86/fred: Clear WFE in missing-ENDBRANCH #CPsXin Li (Intel)
An indirect branch instruction sets the CPU indirect branch tracker (IBT) into WAIT_FOR_ENDBRANCH (WFE) state and WFE stays asserted across the instruction boundary. When the decoder finds an inappropriate instruction while WFE is set ENDBR, the CPU raises a #CP fault. For the "kernel IBT no ENDBR" selftest where #CPs are deliberately triggered, the WFE state of the interrupted context needs to be cleared to let execution continue. Otherwise when the CPU resumes from the instruction that just caused the previous #CP, another missing-ENDBRANCH #CP is raised and the CPU enters a dead loop. This is not a problem with IDT because it doesn't preserve WFE and IRET doesn't set WFE. But FRED provides space on the entry stack (in an expanded CS area) to save and restore the WFE state, thus the WFE state is no longer clobbered, so software must clear it. Clear WFE to avoid dead looping in ibt_clear_fred_wfe() and the !ibt_fatal code path when execution is allowed to continue. Clobbering WFE in any other circumstance is a security-relevant bug.

2024-12-29freezer, sched: Report frozen tasks as 'D' instead of 'R'Chen Ridong
Before commit: f5d39b020809 ("freezer,sched: Rewrite core freezer logic") the frozen task stat was reported as 'D' in cgroup v1. However, after rewriting the core freezer logic, the frozen task stat is reported as 'R'. This is confusing, especially when a task with stat of 'S' is frozen. This bug can be reproduced with these steps: $ cd /sys/fs/cgroup/freezer/ $ mkdir test $ sleep 1000 & [1] 739 // task whose stat is 'S' $ echo 739 > test/cgroup.procs $ echo FROZEN > test/freezer.state $ ps -aux | grep 739 root 739 0.1 0.0 8376 1812 pts/0 R 10:56 0:00 sleep 1000 As shown above, a task whose stat is 'S' was changed to 'R' when it was frozen. To solve this regression, simply maintain the same reported state as before the rewrite.

2024-12-27net: llc: reset skb->transport_headerAntonio Pastor
802.2+LLC+SNAP frames received by napi_complete_done with GRO and DSA have skb->transport_header set two bytes short, or pointing 2 bytes before network_header & skb->data. As snap_rcv expects transport_header to point to SNAP header (OID:PID) after LLC processing advances offset over LLC header (llc_rcv & llc_fixup_skb), code doesn't find a match and packet is dropped. Between napi_complete_done and snap_rcv, transport_header is not used until __netif_receive_skb_core, where originally it was being reset. Commit fda55eca5a33 ("net: introduce skb_transport_header_was_set()") only does so if not set, on the assumption the value was set correctly by GRO (and also on assumption that "network stacks usually reset the transport header anyway"). Afterwards it is moved forward by llc_fixup_skb. Locally generated traffic shows up at __netif_receive_skb_core with no transport_header set and is processed without issue. On a setup with GRO but no DSA, transport_header and network_header are both set to point to skb->data which is also correct. As issue is LLC specific, to avoid impacting non-LLC traffic, and to follow up on original assumption made on previous code change, llc_fixup_skb to reset the offset after skb pull. llc_fixup_skb assumes the LLC header is at skb->data, and by definition SNAP header immediately follows.

2024-12-27rtla/timerlat: Fix histogram ALL for zero samplesTomas Glozar
rtla timerlat hist currently computers the minimum, maximum and average latency even in cases when there are zero samples. This leads to nonsensical values being calculated for maximum and minimum, and to divide by zero for average. A similar bug is fixed by 01b05fc0e5f3 ("rtla/timerlat: Fix histogram report when a cpu count is 0") but the bug still remains for printing the sum over all CPUs in timerlat_print_stats_all. The issue can be reproduced with this command: $ rtla timerlat hist -U -d 1s Index over: count: min: avg: max: Floating point exception (core dumped) (There are always no samples with -U unless the user workload is created.) Fix the bug by omitting max/min/avg when sample count is zero, displaying a dash instead, just like we already do for the individual CPUs. The logic is moved into a new function called format_summary_value, which is used for both the individual CPUs and for the overall summary.
