2023-10-27Make out-of-swap checks more robust.Martin Pieuchot
Consider that the swap space is full when 99% of it is filled with pages that are no longer present in memory. This prevents deadlocks when out-of-swap if some swap ranges had I/O errors and have been marked as 'bad', or if some pages are unreachable by the pagedaemon and still holding some slots. Also introduce uvm_swapisfilled() to check if there are some free slots in the swap. Note that we consider the swap space completly filled if it is not possible to write a full cluster. This prevents deadlocks if a few slots are never allocated. ok miod@

2023-10-24Normally context switches happen in mi_switch() but there are 3 casesClaudio Jeker
where a switch happens outside. Cleanup these code paths and make the machine independent. - when a process forks (fork, tfork, kthread), the new proc needs to somehow be scheduled for the first time. This is done by proc_trampoline. Since proc_trampoline is machine dependent assembler code change the MP specific proc_trampoline_mp() to proc_trampoline_mi() and make sure it is now always called. - cpu_hatch: when booting APs the code needs to jump to the first proc running on that CPU. This should be the idle thread for that CPU. - sched_exit: when a proc exits it needs to switch away from itself and then instruct the reaper to clean up the rest. This is done by switching to the idle loop. Since the last two cases require a context switch to the idle proc factor out the common code to sched_toidle() and use it in those places. Tested by many on all archs. OK miod@ mpi@ cheloha@

2023-10-23Prevent wg(4) stuck on peer destruction.Vitaliy Makkoveev
While interface going down and output stopped, packets could rest in `if_snd' queue. So the (!ifq_empty(&sc->sc_if.if_snd)) condition will always be true and wg_peer_destroy() will sleep until interface became up and stuck packets transmitted. Check IFF_RUNNING flag within (!ifq_empty(&sc->sc_if.if_snd)) loop in wg_peer_destroy(). If the flag is not set that means interface is down, so drain the `if_snd' queue manually to prevent wg_peer_destroy() stuck. Problem reported and fix tested by Kirill Miazine. ok bluhm@
2023-10-22fix 40 MHz channel validation checks for the 2.4 GHz channel rangeStefan Sperling
Just like the 5 GHz channels, 2.4 GHz channels are spaced 5 MHz apart. 40 MHz wide channels hence span channels [N, N + 4] not [N, N + 1]. Adjust our secondary channel range checks accordingly.
2023-10-21ignore wide channel configs that do not appear in the 802.11ac specStefan Sperling
Wide channel configurations not listed in operating class tables of the 802.11ac spec can trigger regulatory assertion failures in iwm(4) firmware, and potentially other device firmware. Ignore non-standard channels configs such that we downgrade to 40MHz or even 20MHz to make such APs usable, albeit at lower speed. Found by dlg@ with a mikrotik AP advertising channel configs that do not appear as such in the spec: 80 MHz: |104|108|112|116| 40 MHz: |primary: 112|secondary above: 116| Either of these triggered iwm0: 0x000014FD | ADVANCED_SYSASSERT Fix tested by myself on iwx(4) AX200 and dlg@ on iwm(4) 7260. Johannes Berg helped with deciphering the error code, thanks!

2023-10-20Avoid assertion failure when splitting mbuf cluster.Alexander Bluhm
m_split() calls m_align() to initialize the data pointer of newly allocated mbuf. If the new mbuf will be converted to a cluster, this is not necessary. If additionally the new mbuf is larger than MLEN, this can lead to a panic. Only call m_align() when a valid m_data is needed. This is the case if we do not refecence the existing cluster, but memcpy() the data into the new mbuf. Reported-by: syzbot+0e6817f5877926f0e96a@syzkaller.appspotmail.com OK claudio@ deraadt@

2023-10-17clockintr: move callback-specific API behaviors to "clockrequest" namespaceScott Soule Cheloha
The API's behavior when invoked from a callback function is impossible to document. Move the special behavior into a distinct namespace, "clockrequest". - Add a 'struct clockrequest'. Basically a stripped-down 'struct clockintr' for exclusive use during clockintr_dispatch(). - In clockintr_queue, replace the "cq_shadow" clockintr with a "cq_request" clockrequest. They serve the same purpose. - CLST_SHADOW_PENDING -> CR_RESCHEDULE; different namespace, same meaning. - CLST_IGNORE_SHADOW -> CLST_IGNORE_REQUEST; same meaning. - Move shadow branch in clockintr_advance() to clockrequest_advance(). - clockintr_request_random() becomes clockrequest_advance_random(). - Delete dead shadow branches in clockintr_cancel(), clockintr_schedule(). - Callback functions now get a clockrequest pointer instead of a special clockintr pointer: update all prototypes, callers. No functional change intended.
2023-10-16Consider required constraint when moving pages from active to inactive lists.Martin Pieuchot
Make sure low pages are deactivated first when there is a shortage of inactive pages. Without this the system can have a ton of high pages on the active list and never swapout anything if there's a shortage of low pages. This prevents a deadlock on amd64 reported and tested by bluhm@. ok kettenis@

2023-10-12pflog(4) logs packet dropped by default rule with block.Alexander Bluhm
If a packet is malformed, it is dropped by pf(4). The rule referenced in pflog(4) is the default rule. As the default rule is a pass rule, tcpdump printed "pass" although the packet was actually dropped. To avoid confusion, change the action to drop. Then tcpdump prints "block". OK sashan@ kn@
2023-10-12timeout: add TIMEOUT_MPSAFE flagScott Soule Cheloha
Add a TIMEOUT_MPSAFE flag to signal that a timeout is safe to run without the kernel lock. Currently, TIMEOUT_MPSAFE requires TIMEOUT_PROC. When the softclock() is unlocked in the future this dependency will be removed. On MULTIPROCESSOR kernels, softclock() now shunts TIMEOUT_MPSAFE timeouts to a dedicated "timeout_proc_mp" bucket for processing by the dedicated softclock_thread_mp() kthread. Unlike softclock_thread(), softclock_thread_mp() is not pinned to any CPU and runs run at IPL_NONE. Prompted by bluhm@. Lots of input from bluhm@. Joint work with mvs@.

2023-10-11Prevent deref-after-free when tdb_timeout() fires on invalid new tdb.Tobias Heider
When receiving a pfkeyv2 SADB_ADD message, a newly created tdb can fail in tdb_init(), which causes the tdb to not get added to the global tdb list and an immediate dereference. If a lifetime timeout triggers on this tdb, it will unconditionally try to remove it from the list and in the process deref once more than allowed, causing a one bit corruption in the already freed up slot in the tdb pool. We resolve this issue by moving timeout_add() after tdb_init() just before puttdb(). This means tdbs failing initialization get discarded immediately as they only hold a single reference. Valid tdbs get their timeouts activated just before we add them to the tdb list, meaning the timeout can safely assume they are linked. Feedback from mvs@ and millert@ ok mvs@ mbuhl@
2023-10-11kernel: expand fixed clock interrupt periods to 64-bit valuesScott Soule Cheloha
Technically, all the current fixed clock interrupt periods fit within an unsigned 32-bit value. But 32-bit multiplication is an accident waiting to happen. So, expand the fixed periods for hardclock, statclock, profclock, and roundrobin to 64-bit values. One exception: statclock_mask remains 32-bit because random(9) yields 32-bit values. Update the initclocks() comment to make it clear that this is not an accident.

2023-10-10pf(4) must not pass packet if state cannot be created.Alexander Bluhm
The behavior of the PFRULE_SRCTRACK and max_states check was unintentionally changed by commit revision 1.964. If the state was not created due to some limit had been reached, pf still passed the packet. Restore the old logic by setting action to pass later, after the checks. In pf_test_rule() action is initialized to drop. OK sashan@
