2022-11-25net: microchip: sparx5: Add VCAP filter keys KUNIT testSteen Hegelund
This tests the filtering of keys, either dropping unsupported keys or dropping keys specified in a list. Signed-off-by: Steen Hegelund <steen.hegelund@microchip.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2022-11-25net: microchip: sparx5: Support for displaying a list of keysetsSteen Hegelund
This will display a list of keyset in case the type_id field in the VCAP rule has been wildcarded. Signed-off-by: Steen Hegelund <steen.hegelund@microchip.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2022-11-25net: microchip: sparx5: Support for TC protocol allSteen Hegelund
This allows support of TC protocol all for the Sparx5 IS2 VCAP. This is done by creating multiple rules that covers the rule size and traffic types in the IS2. Each rule size (e.g X16 and X6) may have multiple keysets and if there are more than one the type field in the VCAP rule will be wildcarded to support these keysets.

2022-11-25net: loopback: use NET_NAME_PREDICTABLE for name_assign_typeRasmus Villemoes
When the name_assign_type attribute was introduced (commit 685343fc3ba6, "net: add name_assign_type netdev attribute"), the loopback device was explicitly mentioned as one which would make use of NET_NAME_PREDICTABLE: The name_assign_type attribute gives hints where the interface name of a given net-device comes from. These values are currently defined: ... NET_NAME_PREDICTABLE: The ifname has been assigned by the kernel in a predictable way that is guaranteed to avoid reuse and always be the same for a given device. Examples include statically created devices like the loopback device [...] Switch to that so that reading /sys/class/net/lo/name_assign_type produces something sensible instead of returning -EINVAL.

2022-11-25net: fec: don't reset irq coalesce settings to defaults on "ip link up"Rasmus Villemoes
Currently, when a FEC device is brought up, the irq coalesce settings are reset to their default values (1000us, 200 frames). That's unexpected, and breaks for example use of an appropriate .link file to make systemd-udev apply the desired settings (https://www.freedesktop.org/software/systemd/man/systemd.link.html), or any other method that would do a one-time setup during early boot. Refactor the code so that fec_restart() instead uses fec_enet_itr_coal_set(), which simply applies the settings that are stored in the private data, and initialize that private data with the default values.

2022-11-25octeontx2-pf: Fix pfc_alloc_status array overflowSuman Ghosh
This patch addresses pfc_alloc_status array overflow occurring for send queue index value greater than PFC priority. Queue index can be greater than supported PFC priority for multiple scenarios (e.g. QoS, during non zero SMQ allocation for a PF/VF). In those scenarios the API should return default tx scheduler '0'. This is causing mbox errors as otx2_get_smq_idx returing invalid smq value.

2022-11-25qlcnic: fix sleep-in-atomic-context bugs caused by msleepDuoming Zhou
The watchdog timer is used to monitor whether the process of transmitting data is timeout. If we use qlcnic driver, the dev_watchdog() that is the timer handler of watchdog timer will call qlcnic_tx_timeout() to process the timeout. But the qlcnic_tx_timeout() calls msleep(), as a result, the sleep-in-atomic-context bugs will happen.

2022-11-25vfs: fix copy_file_range() averts filesystem freeze protectionAmir Goldstein
Commit 868f9f2f8e00 ("vfs: fix copy_file_range() regression in cross-fs copies") removed fallback to generic_copy_file_range() for cross-fs cases inside vfs_copy_file_range(). To preserve behavior of nfsd and ksmbd server-side-copy, the fallback to generic_copy_file_range() was added in nfsd and ksmbd code, but that call is missing sb_start_write(), fsnotify hooks and more. Ideally, nfsd and ksmbd would pass a flag to vfs_copy_file_range() that will take care of the fallback, but that code would be subtle and we got vfs_copy_file_range() logic wrong too many times already. Instead, add a flag to explicitly request vfs_copy_file_range() to perform only generic_copy_file_range() and let nfsd and ksmbd use this flag only in the fallback path. This choise keeps the logic changes to minimum in the non-nfsd/ksmbd code paths to reduce the risk of further regressions.

2022-11-24bpf: Don't mark arguments to fentry/fexit programs as trusted.Alexei Starovoitov
The PTR_TRUSTED flag should only be applied to pointers where the verifier can guarantee that such pointers are valid. The fentry/fexit/fmod_ret programs are not in this category. Only arguments of SEC("tp_btf") and SEC("iter") programs are trusted (which have BPF_TRACE_RAW_TP and BPF_TRACE_ITER attach_type correspondingly) This bug was masked because convert_ctx_accesses() was converting trusted loads into BPF_PROBE_MEM loads.

2022-11-24Merge branch 'bpf: Add bpf_rcu_read_lock() support'Alexei Starovoitov
Yonghong Song says: ==================== Currently, without rcu attribute info in BTF, the verifier treats rcu tagged pointer as a normal pointer. This might be a problem for sleepable program where rcu_read_lock()/unlock() is not available. For example, for a sleepable fentry program, if rcu protected memory access is interleaved with a sleepable helper/kfunc, it is possible the memory access after the sleepable helper/kfunc might be invalid since the object might have been freed then. Even without a sleepable helper/kfunc, without rcu_read_lock() protection, it is possible that the rcu protected object might be release in the middle of bpf program execution which may cause incorrect result. To prevent above cases, enable btf_type_tag("rcu") attributes, introduce new bpf_rcu_read_lock/unlock() kfuncs and add verifier support. In the rest of patch set, Patch 1 enabled btf_type_tag for __rcu attribute. Patche 2 added might_sleep in bpf_func_proto. Patch 3 added new bpf_rcu_read_lock/unlock() kfuncs and verifier support. Patch 4 added some tests for these two new kfuncs. Changelogs: v9 -> v10: . if no rcu tag support in vmlinux btf, using bpf_rcu_read_lock/unlock() will cause verification error. . at bpf_rcu_read_unlock(), invalidate rcu ptr to PTR_UNTRUSTED instead of SCALAR_VALUE. . a few other comment changes and other minor changes. v8 -> v9: . remove sleepable prog check for ld_abs/ind checking in rcu read lock region. . fix a test failure with gcc-compiled kernel. . a couple of other minor fixes. v7 -> v8: . add might_sleep in bpf_func_proto so we can easily identify whether a helper is sleepable or not. . do not enforce rcu rules for sleepable, e.g., rcu dereference must be in a bpf_rcu_read_lock region. This is to keep old code working fine. . Mark 'b' in 'b = a->b' (b is tagged with __rcu) as MEM_RCU only if 'b = a->b' in rcu read region and 'a' is trusted. This adds safety guarantee for 'b' inside the rcu read region. v6 -> v7: . rebase on top of bpf-next. . remove the patch which enables sleepable program using cgrp_local_storage map. This is orthogonal to this patch set and will be addressed separately. . mark the rcu pointer dereference result as UNTRUSTED if inside a bpf_rcu_read_lock() region. v5 -> v6: . fix selftest prog miss_unlock which tested nested locking. . add comments in selftest prog cgrp_succ to explain how to handle nested memory access after rcu memory load. v4 -> v5: . add new test to aarch64 deny list. v3 -> v4: . fix selftest failures when built with gcc. gcc doesn't support btf_type_tag yet and some tests relies on that. skip these tests if vmlinux BTF does not have btf_type_tag("rcu"). v2 -> v3: . went back to MEM_RCU approach with invalidate rcu ptr registers at bpf_rcu_read_unlock() place. . remove KF_RCU_LOCK/UNLOCK flag and compare btf_id at verification time instead. v1 -> v2: . use kfunc instead of helper for bpf_rcu_read_lock/unlock. . not use MEM_RCU bpf_type_flag, instead use active_rcu_lock in reg state to identify rcu ptr's. . Add more self tests. . add new test to s390x deny list. ==================== Signed-off-by: Alexei Starovoitov <ast@kernel.org>

2022-11-24bpf: Add kfunc bpf_rcu_read_lock/unlock()Yonghong Song
Add two kfunc's bpf_rcu_read_lock() and bpf_rcu_read_unlock(). These two kfunc's can be used for all program types. The following is an example about how rcu pointer are used w.r.t. bpf_rcu_read_lock()/bpf_rcu_read_unlock(). struct task_struct { ... struct task_struct *last_wakee; struct task_struct __rcu *real_parent; ... }; Let us say prog does 'task = bpf_get_current_task_btf()' to get a 'task' pointer. The basic rules are: - 'real_parent = task->real_parent' should be inside bpf_rcu_read_lock region. This is to simulate rcu_dereference() operation. The 'real_parent' is marked as MEM_RCU only if (1). task->real_parent is inside bpf_rcu_read_lock region, and (2). task is a trusted ptr. So MEM_RCU marked ptr can be 'trusted' inside the bpf_rcu_read_lock region. - 'last_wakee = real_parent->last_wakee' should be inside bpf_rcu_read_lock region since it tries to access rcu protected memory. - the ptr 'last_wakee' will be marked as PTR_UNTRUSTED since in general it is not clear whether the object pointed by 'last_wakee' is valid or not even inside bpf_rcu_read_lock region. The verifier will reset all rcu pointer register states to untrusted at bpf_rcu_read_unlock() kfunc call site, so any such rcu pointer won't be trusted any more outside the bpf_rcu_read_lock() region. The current implementation does not support nested rcu read lock region in the prog.

2022-11-24compiler_types: Define __rcu as __attribute__((btf_type_tag("rcu")))Yonghong Song
Currently, without rcu attribute info in BTF, the verifier treats rcu tagged pointer as a normal pointer. This might be a problem for sleepable program where rcu_read_lock()/unlock() is not available. For example, for a sleepable fentry program, if rcu protected memory access is interleaved with a sleepable helper/kfunc, it is possible the memory access after the sleepable helper/kfunc might be invalid since the object might have been freed then. To prevent such cases, introducing rcu tagging for memory accesses in verifier can help to reject such programs. To enable rcu tagging in BTF, during kernel compilation, define __rcu as attribute btf_type_tag("rcu") so __rcu information can be preserved in dwarf and btf, and later can be used for bpf prog verification.

2022-11-24can: mcba_usb: Fix termination command argumentYasushi SHOJI
Microchip USB Analyzer can activate the internal termination resistors by setting the "termination" option ON, or OFF to to deactivate them. As I've observed, both with my oscilloscope and captured USB packets below, you must send "0" to turn it ON, and "1" to turn it OFF. From the schematics in the user's guide, I can confirm that you must drive the CAN_RES signal LOW "0" to activate the resistors. Reverse the argument value of usb_msg.termination to fix this. These are the two commands sequence, ON then OFF. > No. Time Source Destination Protocol Length Info > 1 0.000000 host 1.3.1 USB 46 URB_BULK out > > Frame 1: 46 bytes on wire (368 bits), 46 bytes captured (368 bits) > USB URB > Leftover Capture Data: a80000000000000000000000000000000000a8 > > No. Time Source Destination Protocol Length Info > 2 4.372547 host 1.3.1 USB 46 URB_BULK out > > Frame 2: 46 bytes on wire (368 bits), 46 bytes captured (368 bits) > USB URB > Leftover Capture Data: a80100000000000000000000000000000000a9 Signed-off-by: Yasushi SHOJI <yashi@spacecubics.com> Link: https://lore.kernel.org/all/20221124152504.125994-1-yashi@spacecubics.com Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de>
