The read and writes from the fifo are from a buffer, with various fields and data at predefined offsets. So, they should not be done to the same address(or port) in case of val_count greater than 1. Therefore, fix this by using iowrite32()/ioread32() instead of ioread32_rep()/iowrite32_rep(). Also, the write into FIFO must be performed with an offset from the message ram base address. Therefore, fix the base address to mram_base. Fixes: e3938177 ("can: m_can: Disable IRQs on FIFO bus errors") Link: https://lore.kernel.org/all/20210920123344.2320-1-a-govindraju@ti.comSigned-off-by:

When isotp_sendmsg() concurrent, tx.state of all TX processes can be ISOTP_IDLE. The conditions so->tx.state != ISOTP_IDLE and wq_has_sleeper(&so->wait) can not protect TX buffer from being accessed by multiple TX processes. We can use cmpxchg() to try to modify tx.state to ISOTP_SENDING firstly. If the modification of the previous process succeed, the later process must wait tx.state to ISOTP_IDLE firstly. Thus, we can ensure TX buffer is accessed by only one process at the same time. And we should also restore the original tx.state at the subsequent error processes.

Using wait_event_interruptible() to wait for complete transmission, but do not check the result of wait_event_interruptible() which can be interrupted.

When the session state is J1939_SESSION_DONE, j1939_tp_rxtimer() will give an alert "rx timeout, send abort", but do nothing actually. Move the alert into session active judgment condition, it is more reasonable. One of the scenarios is that j1939_tp_rxtimer() execute followed by j1939_xtp_rx_abort_one(). After j1939_xtp_rx_abort_one(), the session state is J1939_SESSION_DONE, then j1939_tp_rxtimer() give an alert.

When I added IGMPv3 support I decided to follow the RFC for computing the GMI dynamically: " 8.4. Group Membership Interval The Group Membership Interval is the amount of time that must pass before a multicast router decides there are no more members of a group or a particular source on a network. This value MUST be ((the Robustness Variable) times (the Query Interval)) plus (one Query Response Interval)." But that actually is inconsistent with how the bridge used to compute it for IGMPv2, where it was user-configurable that has a correct default value but it is up to user-space to maintain it. This would make it consistent with the other timer values which are also maintained correct by the user instead of being dynamically computed. It also changes back to the previous user-expected GMI behaviour for IGMPv3 queries which were supported before IGMPv3 was added. Note that to properly compute it dynamically we would need to add support for "Robustness Variable" which is currently missing. Reported-by:

In `test_no_sockets` we don't expect any sockets, indeed check_no_sockets() prints an error and exits if `sockets` list is not empty, so free_sock_stat() call is unnecessary since it would only be called when the `sockets` list is empty. This was discovered by a strange warning printed by gcc v11.2.1: In file included from ../../include/linux/list.h:7, from vsock_diag_test.c:18: vsock_diag_test.c: In function ‘test_no_sockets’: ../../include/linux/kernel.h:35:45: error: array subscript ‘struct vsock_stat[0]’ is partly outside array bound s of ‘struct list_head[1]’ [-Werror=array-bounds] 35 | const typeof(((type *)0)->member) * __mptr = (ptr); \ | ^~~~~~ ../../include/linux/list.h:352:9: note: in expansion of macro ‘container_of’ 352 | container_of(ptr, type, member) | ^~~~~~~~~~~~ ../../include/linux/list.h:393:9: note: in expansion of macro ‘list_entry’ 393 | list_entry((pos)->member.next, typeof(*(pos)), member) | ^~~~~~~~~~ ../../include/linux/list.h:522:21: note: in expansion of macro ‘list_next_entry’ 522 | n = list_next_entry(pos, member); \ | ^~~~~~~~~~~~~~~ vsock_diag_test.c:325:9: note: in expansion of macro ‘list_for_each_entry_safe’ 325 | list_for_each_entry_safe(st, next, sockets, list) { | ^~~~~~~~~~~~~~~~~~~~~~~~ In file included from vsock_diag_test.c:18: vsock_diag_test.c:333:19: note: while referencing ‘sockets’ 333 | LIST_HEAD(sockets); | ^~~~~~~ ../../include/linux/list.h:23:26: note: in definition of macro ‘LIST_HEAD’ 23 | struct list_head name = LIST_HEAD_INIT(name) It seems related to some compiler optimization and assumption about the empty `sockets` list, since this warning is printed only with -02 or -O3. Also removing `exit(1)` from check_no_sockets() makes the warning disappear since in that case free_sock_stat() can be reached also when the list is not empty.

Leonard Crestez says: ==================== tcp: md5: Fix overlap between vrf and non-vrf keys With net.ipv4.tcp_l3mdev_accept=1 it is possible for a listen socket to accept connection from the same client address in different VRFs. It is also possible to set different MD5 keys for these clients which differ only in the tcpm_l3index field. This appears to work when distinguishing between different VRFs but not between non-VRF and VRF connections. In particular: * tcp_md5_do_lookup_exact will match a non-vrf key against a vrf key. This means that adding a key with l3index != 0 after a key with l3index == 0 will cause the earlier key to be deleted. Both keys can be present if the non-vrf key is added later. * _tcp_md5_do_lookup can match a non-vrf key before a vrf key. This casues failures if the passwords differ. This can be fixed by making tcp_md5_do_lookup_exact perform an actual exact comparison on l3index and by making __tcp_md5_do_lookup perfer vrf-bound keys above other considerations like prefixlen. The fact that keys with l3index==0 affect VRF connections is usually not desirable, VRFs are meant to be completely independent. This behavior needs to preserved for backwards compatibility. Also, applications can just bind listen sockets to VRF and never specify TCP_MD5SIG_FLAG_IFINDEX at all. So far the combination of TCP_MD5SIG_FLAG_IFINDEX with tcpm_ifindex == 0 was an error, accept this to mean "key only applies to default VRF". This is what applications using VRFs for traffic separation want. This also contains tests for the second part. It does not contain tests for overlapping keys, that would require more changes in nettest to add multiple keys. These scenarios are also covered by my tests for TCP-AO, especially around this area: https://github.com/cdleonard/tcp-authopt-test/blob/main/tcp_authopt_test/test_vrf_bind.py Changes since V2: * Rename --do-bind-key-ifindex to --force-bind-key-ifindex * Fix referencing TCP_MD5SIG_FLAG_IFINDEX as TCP_MD5SIG_IFINDEX Link to v2: https://lore.kernel.org/netdev/cover.1634107317.git.cdleonard@gmail.com/ Changes since V1: * Accept (TCP_MD5SIG_IFINDEX with tcpm_ifindex == 0) * Add flags for explicitly including or excluding TCP_MD5SIG_FLAG_IFINDEX to nettest * Add few more tests in fcnal-test.sh.

Test that applications binding listening sockets to VRFs without specifying TCP_MD5SIG_FLAG_IFINDEX will work as expected. This would be broken if __tcp_md5_do_lookup always made a strict comparison on l3index. See this email: https://lore.kernel.org/netdev/209548b5-27d2-2059-f2e9-2148f5a0291b@gmail.com/ Applications using tcp_l3mdev_accept=1 and a single global socket (not bound to any interface) also should have a way to specify keys that are only for the default VRF, this is done by --force-bind-key-ifindex without otherwise binding to a device.

These options allow explicit control over the TCP_MD5SIG_FLAG_IFINDEX flag instead of always setting it based on binding to an interface. Do this by converting to getopt_long because nettest has too many single-character flags already and getopt_long is widely used in selftests. Signed-off-by:

Commit a86ed2cf ("ptp: Don't print an error if ptp_kvm is not supported") fixes the error message print on ARM platform by only concerning about the case that the error returned from kvm_arch_ptp_init() is not -EOPNOTSUPP. Although the ARM platform returns -EOPNOTSUPP if ptp_kvm is not supported while X86_64 platform returns -KVM_EOPNOTSUPP, both error codes share the same value 95. Actually kvm_arch_ptp_init() on X86_64 platform can return three kinds of errors (-KVM_ENOSYS, -KVM_EOPNOTSUPP and -KVM_EFAULT). The problem is that -KVM_EOPNOTSUPP is masked out and -KVM_EFAULT is ignored among them. This patch fixes this by returning them to ptp_kvm_init() respectively. Signed-off-by:

In the remove path, there is an attempt to free the aux_idx IDA whether it was allocated or not. This can potentially cause a crash when unloading the driver on systems that do not initialize support for RDMA. But, this free cannot be gated by the status bit for RDMA, since it is allocated if the driver detects support for RDMA at probe time, but the driver can enter into a state where RDMA is not supported after the IDA has been allocated at probe time and this would lead to a memory leak. Initialize aux_idx to an invalid value and check for a valid value when unloading to determine if an IDA free is necessary. Fixes: d25a0fc4 ("ice: Initialize RDMA support") Reported-by:

Currently if the VSI is rebuilt/removed and the RDMA PF driver is active the RDMA Tx queue scheduler node configuration will not be cleaned up. This will cause the rebuild/re-add of the VSI to fail due to the software structures not being correctly cleaned up for the VSI index. Fix this by always calling ice_rm_vsi_rdma_cfg() for all VSI. If there are no RDMA scheduler nodes created, then there is no harm in calling ice_rm_vsi_rdma_cfg(). This change applies to all VSI types, so if RDMA support is added for other VSI types they will also get this change. Fixes: 348048e7 ("ice: Implement iidc operations") Signed-off-by:

In icmp_build_probe(), the icmp_ext_echo_iio parsing should be done step by step and skb_header_pointer() return value should always be checked, this patch fixes 3 places in there: - On case ICMP_EXT_ECHO_CTYPE_NAME, it should only copy ident.name from skb by skb_header_pointer(), its len is ident_len. Besides, the return value of skb_header_pointer() should always be checked. - On case ICMP_EXT_ECHO_CTYPE_INDEX, move ident_len check ahead of skb_header_pointer(), and also do the return value check for skb_header_pointer(). - On case ICMP_EXT_ECHO_CTYPE_ADDR, before accessing iio->ident.addr. ctype3_hdr.addrlen, skb_header_pointer() should be called first, then check its return value and ident_len. On subcases ICMP_AFI_IP and ICMP_AFI_IP6, also do check for ident. addr.ctype3_hdr.addrlen and skb_header_pointer()'s return value. On subcase ICMP_AFI_IP, the len for skb_header_pointer() should be "sizeof(iio->extobj_hdr) + sizeof(iio->ident.addr.ctype3_hdr) + sizeof(struct in_addr)" or "ident_len". v1->v2: - To make it more clear, call skb_header_pointer() once only for iio->indent's parsing as Jakub Suggested. v2->v3: - The extobj_hdr.length check against sizeof(_iio) should be done before calling skb_header_pointer(), as Eric noticed.

sctp_make_strreset_req() makes repeated calls to sctp_addto_chunk() which will automatically account for padding on each call. inreq and outreq are already 4 bytes aligned, but the payload is not and doing SCTP_PAD4(a + b) (which _sctp_make_chunk() did implicitly here) is different from SCTP_PAD4(a) + SCTP_PAD4(b) and not enough. It led to possible attempt to use more buffer than it was allocated and triggered a BUG_ON.

Currently, mlxsw allows cooling states to be set above the maximum cooling state supported by the driver: # cat /sys/class/thermal/thermal_zone2/cdev0/type mlxsw_fan # cat /sys/class/thermal/thermal_zone2/cdev0/max_state 10 # echo 18 > /sys/class/thermal/thermal_zone2/cdev0/cur_state # echo $? 0 This results in out-of-bounds memory accesses when thermal state transition statistics are enabled (CONFIG_THERMAL_STATISTICS=y), as the transition table is accessed with a too large index (state) [1]. According to the thermal maintainer, it is the responsibility of the driver to reject such operations [2]. Therefore, return an error when the state to be set exceeds the maximum cooling state supported by the driver. To avoid dead code, as suggested by the thermal maintainer [3], partially revert commit a421ce08 ("mlxsw: core: Extend cooling device with cooling levels") that tried to interpret these invalid cooling states (above the maximum) in a special way. The cooling levels array is not removed in order to prevent the fans going below 20% PWM, which would cause them to get stuck at 0% PWM.

This reverts commit ec18e845. It turns out that there are user space programs which got broken by that change. One example is the "ifstat" program shipped by Debian: https://packages.debian.org/source/bullseye/ifstat which, confusingly enough, seems to not have anything in common with the much more familiar (at least to me) ifstat program from iproute2: https://git.kernel.org/pub/scm/network/iproute2/iproute2.git/tree/misc/ifstat.c root@debian:~# ifstat ifstat: /proc/net/dev: unsupported format.

Even if we fix this ancient and very "lightly" maintained program to parse the text output of /proc/net/dev in a more sensible way, this story seems bound to repeat again with other programs, and modifying them all could cause more trouble than it's worth. On the other hand, the reverted patch had no other reason than an aesthetic one, so reverting it is the simplest way out. I don't know what other distributions would be affected; the fact that Debian doesn't ship the iproute2 version of the program (a different code base altogether, which uses netlink and not /proc/net/dev) is surprising in itself.
