2020-09-09nvme-fabrics: allow to queue requests for live queuesSagi Grimberg
Right now we are failing requests based on the controller state (which is checked inline in nvmf_check_ready) however we should definitely accept requests if the queue is live. When entering controller reset, we transition the controller into NVME_CTRL_RESETTING, and then return BLK_STS_RESOURCE for non-mpath requests (have blk_noretry_request set). This is also the case for NVME_REQ_USER for the wrong reason. There shouldn't be any reason for us to reject this I/O in a controller reset. We do want to prevent passthru commands on the admin queue because we need the controller to fully initialize first before we let user passthru admin commands to be issued. In a non-mpath setup, this means that the requests will simply be requeued over and over forever not allowing the q_usage_counter to drop its final reference, causing controller reset to hang if running concurrently with heavy I/O.

2020-09-09powerpc/papr_scm: Limit the readability of 'perf_stats' sysfs attributeVaibhav Jain
The newly introduced 'perf_stats' attribute uses the default access mode of 0444, allowing non-root users to access performance stats of an nvdimm and potentially force the kernel into issuing a large number of expensive hypercalls. Since the information exposed by this attribute cannot be cached it is better to ward off access to this attribute from users who don't need to access to these performance statistics. Hence update the access mode of 'perf_stats' attribute to be only readable by root users.

2020-09-08f2fs: Return EOF on unaligned end of file DIO readGabriel Krisman Bertazi
Reading past end of file returns EOF for aligned reads but -EINVAL for unaligned reads on f2fs. While documentation is not strict about this corner case, most filesystem returns EOF on this case, like iomap filesystems. This patch consolidates the behavior for f2fs, by making it return EOF(0). it can be verified by a read loop on a file that does a partial read before EOF (A file that doesn't end at an aligned address). The following code fails on an unaligned file on f2fs, but not on btrfs, ext4, and xfs. while (done < total) { ssize_t delta = pread(fd, buf + done, total - done, off + done); if (!delta) break; ... } It is arguable whether filesystems should actually return EOF or -EINVAL, but since iomap filesystems support it, and so does the original DIO code, it seems reasonable to consolidate on that.

2020-09-08f2fs: fix indefinite loop scanning for free nidSahitya Tummala
If the sbi->ckpt->next_free_nid is not NAT block aligned and if there are free nids in that NAT block between the start of the block and next_free_nid, then those free nids will not be scanned in scan_nat_page(). This results into mismatch between nm_i->available_nids and the sum of nm_i->free_nid_count of all NAT blocks scanned. And nm_i->available_nids will always be greater than the sum of free nids in all the blocks. Under this condition, if we use all the currently scanned free nids, then it will loop forever in f2fs_alloc_nid() as nm_i->available_nids is still not zero but nm_i->free_nid_count of that partially scanned NAT block is zero. Fix this to align the nm_i->next_scan_nid to the first nid of the corresponding NAT block.

2020-09-08f2fs: Fix type of section block count variablesShin'ichiro Kawasaki
Commit da52f8ade40b ("f2fs: get the right gc victim section when section has several segments") added code to count blocks of each section using variables with type 'unsigned short', which has 2 bytes size in many systems. However, the counts can be larger than the 2 bytes range and type conversion results in wrong values. Especially when the f2fs sections have blocks as many as USHRT_MAX + 1, the count is handled as 0. This triggers eternal loop in init_dirty_segmap() at mount system call. Fix this by changing the type of the variables to block_t.

git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs David Howells says: ==================== rxrpc: Allow more calls to same peer Here are some development patches for AF_RXRPC that allow more simultaneous calls to be made to the same peer with the same security parameters. The current code allows a maximum of 4 simultaneous calls, which limits the afs filesystem to that many simultaneous threads. This increases the limit to 16. To make this work, the way client connections are limited has to be changed (incoming call/connection limits are unaffected) as the current code depends on queuing calls on a connection and then pushing the connection through a queue. The limit is on the number of available connections. This is changed such that there's a limit[*] on the total number of calls systemwide across all namespaces, but the limit on the number of client connections is removed. Once a call is allowed to proceed, it finds a bundle of connections and tries to grab a call slot. If there's a spare call slot, fine, otherwise it will wait. If there's already a waiter, it will try to create another connection in the bundle, unless the limit of 4 is reached (4 calls per connection, giving 16). A number of things throttle someone trying to set up endless connections: - Calls that fail immediately have their conns deleted immediately, - Calls that don't fail immediately have to wait for a timeout, - Connections normally get automatically reaped if they haven't been used for 2m, but this is sped up to 2s if the number of connections rises over 900. This number is tunable by sysctl. [*] Technically two limits - kernel sockets and userspace rxrpc sockets are accounted separately. ==================== Signed-off-by: David S.

2020-09-08ipv6: avoid lockdep issue in fib6_del()Eric Dumazet
syzbot reported twice a lockdep issue in fib6_del() [1] which I think is caused by net->ipv6.fib6_null_entry having a NULL fib6_table pointer. fib6_del() already checks for fib6_null_entry special case, we only need to return earlier. Bug seems to occur very rarely, I have thus chosen a 'bug origin' that makes backports not too complex.

We can use netdev_upper_dev_link() to describe the relationship between a DSA slave and a DSA master. To be precise, a DSA "slave" (switch port) is an "upper" to a DSA "master" (host port). The relationship is "many uppers to one lower", like in the case of VLAN. So, for that reason, we use the same function as VLAN uses. There might be a chance that somebody will try to take hold of this interface and use it immediately after register_netdev() and before netdev_upper_dev_link(). To avoid that, we do the registration and linkage while holding the RTNL, and we use the RTNL-locked cousin of register_netdev(), which is register_netdevice(). Since this warning was not there when lockdep was using dynamic keys for addr_list_lock, we are blaming the lockdep patch itself. The network stack _has_ been using static lockdep keys before, and it _is_ likely that stacked DSA setups have been triggering these lockdep warnings since forever, however I can't test very old kernels on this particular stacked DSA setup, to ensure I'm not in fact introducing regressions.

2020-09-08bpf: Permit map_ptr arithmetic with opcode add and offset 0Yonghong Song
Commit 41c48f3a98231 ("bpf: Support access to bpf map fields") added support to access map fields with CORE support. For example, struct bpf_map { __u32 max_entries; } __attribute__((preserve_access_index)); struct bpf_array { struct bpf_map map; __u32 elem_size; } __attribute__((preserve_access_index)); struct { __uint(type, BPF_MAP_TYPE_ARRAY); __uint(max_entries, 4); __type(key, __u32); __type(value, __u32); } m_array SEC(".maps"); SEC("cgroup_skb/egress") int cg_skb(void *ctx) { struct bpf_array *array = (struct bpf_array *)&m_array; /* .. array->map.max_entries .. */ } In kernel, bpf_htab has similar structure, struct bpf_htab { struct bpf_map map; ... } In the above cg_skb(), to access array->map.max_entries, with CORE, the clang will generate two builtin's. base = &m_array; /* access array.map */ map_addr = __builtin_preserve_struct_access_info(base, 0, 0); /* access array.map.max_entries */ max_entries_addr = __builtin_preserve_struct_access_info(map_addr, 0, 0); max_entries = *max_entries_addr; In the current llvm, if two builtin's are in the same function or in the same function after inlining, the compiler is smart enough to chain them together and generates like below: base = &m_array; max_entries = *(base + reloc_offset); /* reloc_offset = 0 in this case */ and we are fine. But if we force no inlining for one of functions in test_map_ptr() selftest, e.g., check_default(), the above two __builtin_preserve_* will be in two different functions. In this case, we will have code like: func check_hash(): reloc_offset_map = 0; base = &m_array; map_base = base + reloc_offset_map; check_default(map_base, ...) func check_default(map_base, ...): max_entries = *(map_base + reloc_offset_max_entries); In kernel, map_ptr (CONST_PTR_TO_MAP) does not allow any arithmetic. The above "map_base = base + reloc_offset_map" will trigger a verifier failure. ; VERIFY(check_default(&hash->map, map)); 0: (18) r7 = 0xffffb4fe8018a004 2: (b4) w1 = 110 3: (63) *(u32 *)(r7 +0) = r1 R1_w=invP110 R7_w=map_value(id=0,off=4,ks=4,vs=8,imm=0) R10=fp0 ; VERIFY_TYPE(BPF_MAP_TYPE_HASH, check_hash); 4: (18) r1 = 0xffffb4fe8018a000 6: (b4) w2 = 1 7: (63) *(u32 *)(r1 +0) = r2 R1_w=map_value(id=0,off=0,ks=4,vs=8,imm=0) R2_w=invP1 R7_w=map_value(id=0,off=4,ks=4,vs=8,imm=0) R10=fp0 8: (b7) r2 = 0 9: (18) r8 = 0xffff90bcb500c000 11: (18) r1 = 0xffff90bcb500c000 13: (0f) r1 += r2 R1 pointer arithmetic on map_ptr prohibited To fix the issue, let us permit map_ptr + 0 arithmetic which will result in exactly the same map_ptr.

The root bus checks rework in d84c572de1a3 ("PCI: rockchip: Use pci_is_root_bus() to check if bus is root bus") caused a regression whereby in rockchip_pcie_valid_device() if the bus parameter is the root bus and the dev value == 0, the function should return 1 (ie true) without checking if the bus->parent pointer is a root bus because that triggers a NULL pointer dereference.

2020-09-08rxrpc: Allow multiple client connections to the same peerDavid Howells
Allow the number of parallel connections to a machine to be expanded from a single connection to a maximum of four. This allows up to 16 calls to be in progress at the same time to any particular peer instead of 4. Signed-off-by: David Howells <dhowells@redhat.com>
2020-09-08rxrpc: Rewrite the client connection managerDavid Howells
Rewrite the rxrpc client connection manager so that it can support multiple connections for a given security key to a peer. The following changes are made: (1) For each open socket, the code currently maintains an rbtree with the connections placed into it, keyed by communications parameters. This is tricky to maintain as connections can be culled from the tree or replaced within it. Connections can require replacement for a number of reasons, e.g. their IDs span too great a range for the IDR data type to represent efficiently, the call ID numbers on that conn would overflow or the conn got aborted. This is changed so that there's now a connection bundle object placed in the tree, keyed on the same parameters. The bundle, however, does not need to be replaced. (2) An rxrpc_bundle object can now manage the available channels for a set of parallel connections. The lock that manages this is moved there from the rxrpc_connection struct (channel_lock). (3) There'a a dummy bundle for all incoming connections to share so that they have a channel_lock too. It might be better to give each incoming connection its own bundle. This bundle is not needed to manage which channels incoming calls are made on because that's the solely at whim of the client. (4) The restrictions on how many client connections are around are removed. Instead, a previous patch limits the number of client calls that can be allocated. Ordinarily, client connections are reaped after 2 minutes on the idle queue, but when more than a certain number of connections are in existence, the reaper starts reaping them after 2s of idleness instead to get the numbers back down. It could also be made such that new call allocations are forced to wait until the number of outstanding connections subsides. Signed-off-by: David Howells <dhowells@redhat.com>
2020-09-08rxrpc: Impose a maximum number of client callsDavid Howells
Impose a maximum on the number of client rxrpc calls that are allowed simultaneously. This will be in lieu of a maximum number of client connections as this is easier to administed as, unlike connections, calls aren't reusable (to be changed in a subsequent patch).. This doesn't affect the limits on service calls and connections. Signed-off-by: David Howells <dhowells@redhat.com>
