2023-11-07selftests/bpf: get trusted cgrp from bpf_iter__cgroup directlyChuyi Zhou
Commit f49843afde (selftests/bpf: Add tests for css_task iter combining with cgroup iter) added a test which demonstrates how css_task iter can be combined with cgroup iter. That test used bpf_cgroup_from_id() to convert bpf_iter__cgroup->cgroup to a trusted ptr which is pointless now, since with the previous fix, we can get a trusted cgroup directly from bpf_iter__cgroup.

2023-11-07bpf: Let verifier consider {task,cgroup} is trusted in bpf_iter_regChuyi Zhou
BTF_TYPE_SAFE_TRUSTED(struct bpf_iter__task) in verifier.c wanted to teach BPF verifier that bpf_iter__task -> task is a trusted ptr. But it doesn't work well. The reason is, bpf_iter__task -> task would go through btf_ctx_access() which enforces the reg_type of 'task' is ctx_arg_info->reg_type, and in task_iter.c, we actually explicitly declare that the ctx_arg_info->reg_type is PTR_TO_BTF_ID_OR_NULL. Actually we have a previous case like this[1] where PTR_TRUSTED is added to the arg flag for map_iter. This patch sets ctx_arg_info->reg_type is PTR_TO_BTF_ID_OR_NULL | PTR_TRUSTED in task_reg_info. Similarly, bpf_cgroup_reg_info -> cgroup is also PTR_TRUSTED since we are under the protection of cgroup_mutex and we would check cgroup_is_dead() in __cgroup_iter_seq_show(). This patch is to improve the user experience of the newly introduced bpf_iter_css_task kfunc before hitting the mainline. The Fixes tag is pointing to the commit introduced the bpf_iter_css_task kfunc.

2023-11-07RISC-V: Probe misaligned access speed in parallelEvan Green
Probing for misaligned access speed takes about 0.06 seconds. On a system with 64 cores, doing this in smp_callin() means it's done serially, extending boot time by 3.8 seconds. That's a lot of boot time. Instead of measuring each CPU serially, let's do the measurements on all CPUs in parallel. If we disable preemption on all CPUs, the jiffies stop ticking, so we can do this in stages of 1) everybody except core 0, then 2) core 0. The allocations are all done outside of on_each_cpu() to avoid calling alloc_pages() with interrupts disabled. For hotplugged CPUs that come in after the boot time measurement, register CPU hotplug callbacks, and do the measurement there. Interrupts are enabled in those callbacks, so they're fine to do alloc_pages() in.

2023-11-07RISC-V: Show accurate per-hart isa in /proc/cpuinfoEvan Green
In /proc/cpuinfo, most of the information we show for each processor is specific to that hart: marchid, mvendorid, mimpid, processor, hart, compatible, and the mmu size. But the ISA string gets filtered through a lowest common denominator mask, so that if one CPU is missing an ISA extension, no CPUs will show it. Now that we track the ISA extensions for each hart, let's report ISA extension info accurately per-hart in /proc/cpuinfo. We cannot change the "isa:" line, as usermode may be relying on that line to show only the common set of extensions supported across all harts. Add a new "hart isa" line instead, which reports the true set of extensions for that hart.

2023-11-07Merge patch series "riscv: Add remaining module relocations and tests"Palmer Dabbelt
Charlie Jenkins <charlie@rivosinc.com> says: A handful of module relocations were missing, this patch includes the remaining ones. I also wrote some test cases to ensure that module loading works properly. Some relocations cannot be supported in the kernel, these include the ones that rely on thread local storage and dynamic linking. This patch also overhauls the implementation of ADD/SUB/SET/ULEB128 relocations to handle overflow. "Overflow" is different for ULEB128 since it is a variable-length encoding that the compiler can be expected to generate enough space for. Instead of overflowing, ULEB128 will expand into the next 8-bit segment of the location. A psABI proposal [1] was merged that mandates that SET_ULEB128 and SUB_ULEB128 are paired, however the discussion following the merging of the pull request revealed that while the pull request was valid, it would be better for linkers to properly handle this overflow. This patch proactively implements this methodology for future compatibility. This can be tested by enabling KUNIT, RUNTIME_KERNEL_TESTING_MENU, and RISCV_MODULE_LINKING_KUNIT.

2023-11-07net: phylink: initialize carrier state at creationKlaus Kudielka
Background: Turris Omnia (Armada 385); eth2 (mvneta) connected to SFP bus; SFP module is present, but no fiber connected, so definitely no carrier. After booting, eth2 is down, but netdev LED trigger surprisingly reports link active. Then, after "ip link set eth2 up", the link indicator goes away - as I would have expected it from the beginning. It turns out, that the default carrier state after netdev creation is "carrier ok". Some ethernet drivers explicitly call netif_carrier_off during probing, others (like mvneta) don't - which explains the current behaviour: only when the device is brought up, phylink_start calls netif_carrier_off. Fix this for all drivers using phylink, by calling netif_carrier_off in phylink_create.

2023-11-07vsock/virtio: remove socket from connected/bound list on shutdownFilippo Storniolo
If the same remote peer, using the same port, tries to connect to a server on a listening port more than once, the server will reject the connection, causing a "connection reset by peer" error on the remote peer. This is due to the presence of a dangling socket from a previous connection in both the connected and bound socket lists. The inconsistency of the above lists only occurs when the remote peer disconnects and the server remains active. This bug does not occur when the server socket is closed: virtio_transport_release() will eventually schedule a call to virtio_transport_do_close() and the latter will remove the socket from the bound and connected socket lists and clear the sk_buff. However, virtio_transport_do_close() will only perform the above actions if it has been scheduled, and this will not happen if the server is processing the shutdown message from a remote peer. To fix this, introduce a call to vsock_remove_sock() when the server is handling a client disconnect. This is to remove the socket from the bound and connected socket lists without clearing the sk_buff.

While adding a semicolon after the label would resolve this, it is more in line with the kernel as a whole to refactor this block into a standalone function, which means the goto a label construct can just be replaced with a return statement.

2023-11-07tg3: Fix the TX ring stallAlex Pakhunov
The TX ring maintained by the tg3 driver can end up in the state, when it has packets queued for sending but the NIC hardware is not informed, so no progress is made. This leads to a multi-second interruption in network traffic followed by dev_watchdog() firing and resetting the queue. The specific sequence of steps is: 1. tg3_start_xmit() is called at least once and queues packet(s) without updating tnapi->prodmbox (netdev_xmit_more() returns true) 2. tg3_start_xmit() is called with an SKB which causes tg3_tso_bug() to be called. 3. tg3_tso_bug() determines that the SKB is too large, ... if (unlikely(tg3_tx_avail(tnapi) <= frag_cnt_est)) { ... stops the queue, and returns NETDEV_TX_BUSY: netif_tx_stop_queue(txq); ... if (tg3_tx_avail(tnapi) <= frag_cnt_est) return NETDEV_TX_BUSY; 4. Since all tg3_tso_bug() call sites directly return, the code updating tnapi->prodmbox is skipped. 5. The queue is stuck now. tg3_start_xmit() is not called while the queue is stopped. The NIC is not processing new packets because tnapi->prodmbox wasn't updated. tg3_tx() is not called by tg3_poll_work() because the all TX descriptions that could be freed has been freed: /* run TX completion thread */ if (tnapi->hw_status->idx[0].tx_consumer != tnapi->tx_cons) { tg3_tx(tnapi); 6. Eventually, dev_watchdog() fires triggering a reset of the queue. This fix makes sure that the tnapi->prodmbox update happens regardless of the reason tg3_start_xmit() returned.

Filesystems that want to opt out of encoding non-decodable file ids for fanotify that don't support NFS export can do so by providing an empty export_operations struct. This also partially addresses (2) by generating f_fsid for simple filesystems as well as freevxfs. Remaining filesystems will be dealt with by separate patches.

Fixes include: - multiple snapshot deletion fixes - members_v2 fixups - deleted_inodes btree fixes - copygc thread no longer spins when a device is full but has no fragmented buckets (i.e. rebalance needs to move data around instead) - a fix for a memory reclaim issue with the btree key cache: we're now careful not to hold the srcu read lock that blocks key cache reclaim for too long - an early allocator locking fix, from Brian - endianness fixes, from Brian - CONFIG_BCACHEFS_DEBUG_TRANSACTIONS no longer defaults to y, a big performance improvement on multithreaded workloads" * tag 'bcachefs-2023-11-5' of https://evilpiepirate.org/git/bcachefs: (70 commits) bcachefs: Improve stripe checksum error message bcachefs: Simplify, fix bch2_backpointer_get_key() bcachefs: kill thing_it_points_to arg to backpointer_not_found() bcachefs: bch2_ec_read_extent() now takes btree_trans bcachefs: bch2_stripe_to_text() now prints ptr gens bcachefs: Don't iterate over journal entries just for btree roots bcachefs: Break up bch2_journal_write() bcachefs: Replace ERANGE with private error codes bcachefs: bkey_copy() is no longer a macro bcachefs: x-macro-ify inode flags enum bcachefs: Convert bch2_fs_open() to darray bcachefs: Move __bch2_members_v2_get_mut to sb-members.h bcachefs: bch2_prt_datetime() bcachefs: CONFIG_BCACHEFS_DEBUG_TRANSACTIONS no longer defaults to y bcachefs: Add a comment for BTREE_INSERT_NOJOURNAL usage bcachefs: rebalance_work btree is not a snapshots btree bcachefs: Add missing printk newlines bcachefs: Fix recovery when forced to use JSET_NO_FLUSH journal entry bcachefs: .get_parent() should return an error pointer bcachefs: Fix bch2_delete_dead_inodes() ...
2023-11-07parisc/pgtable: Do not drop upper 5 address bits of physical addressHelge Deller
When calculating the pfn for the iitlbt/idtlbt instruction, do not drop the upper 5 address bits. This doesn't seem to have an effect on physical hardware which uses less physical address bits, but in qemu the missing bits are visible.

2023-11-07nvme: common: make keyring and auth separate modulesArnd Bergmann
When only the keyring module is included but auth is not, modpost complains about the lack of a module license tag: ERROR: modpost: missing MODULE_LICENSE() in drivers/nvme/common/nvme-common.o Address this by making both modules buildable standalone, removing the now unnecessary CONFIG_NVME_COMMON symbol in the process. Also, now that NVME_KEYRING config symbol can be either a module or built-in, the stubs need to check for '#if IS_ENABLED' rather than a simple '#ifdef'.
