2019-11-25Merge branch 'maintainer-profile' into docs-nextJonathan Corbet
Patch series from Dan Williams: At last years Plumbers Conference I proposed the Maintainer Entry Profile as a document that a maintainer can provide to set contributor expectations and provide fodder for a discussion between maintainers about the merits of different maintainer policies. For those that did not attend, the goal of the Maintainer Entry Profile is to provide contributors documentation of patch submission considerations that may vary by subsystem. The session introduction was: The first rule of kernel maintenance is that there are no hard and fast rules. That state of affairs is both a blessing and a curse. It has served the community well to be adaptable to the different people and different problem spaces that inhabit the kernel community. However, that variability also leads to inconsistent experiences for contributors, little to no guidance for new contributors, and unnecessary stress on current maintainers. To be clear, the proposed document does not impose or suggest new rules. Instead it provides an outlet to document the existing unwritten policies in effect for a given subsystem. Over time the hope is that some of this variability can be up-levelled to new global process policy, but in the meantime it provides relief for communicating the guidelines that are being imposed on contributors. [jc: resolved merge conflicts with the MAINTAINERS file, added a patch to fix up various RST issues, and added a TOC section for the profiles.]

2019-11-25Maintainer Handbook: Maintainer Entry ProfileDan Williams
As presented at the 2018 Linux Plumbers conference [1], the Maintainer Entry Profile (formerly Subsystem Profile) is proposed as a way to reduce friction between committers and maintainers and encourage conversations amongst maintainers about common best practices. While coding-style, submit-checklist, and submitting-drivers lay out some common expectations there remain local customs and maintainer preferences that vary by subsystem. The profile contains documentation of some of the common policy questions a contributor might have that are local to the subsystem / device-driver, special considerations for the subsystem, or other guidelines that are otherwise not covered by the top-level process documents. The initial and hopefully non-controversial headings in the profile are: Overview: General introduction to how the subsystem operates Submit Checklist Addendum: Mechanical items that gate submission staging, or other requirements that gate patch acceptance. Key Cycle Dates: - Last -rc for new feature submissions: Expected lead time for submissions - Last -rc to merge features: Deadline for merge decisions Resubmit Cadence: When and preferred method to follow up with the maintainer Note that coding style guidelines are explicitly left out of this list. See Documentation/maintainer/maintainer-entry-profile.rst for more details, and a follow-on example profile for the libnvdimm subsystem.

2019-11-25cifs: Fix potential softlockups while refreshing DFS cachePaulo Alcantara (SUSE)
We used to skip reconnects on all SMB2_IOCTL commands due to SMB3+ FSCTL_VALIDATE_NEGOTIATE_INFO - which made sense since we're still establishing a SMB session. However, when refresh_cache_worker() calls smb2_get_dfs_refer() and we're under reconnect, SMB2_ioctl() will not be able to get a proper status error (e.g. -EHOSTDOWN in case we failed to reconnect) but an -EAGAIN from cifs_send_recv() thus looping forever in refresh_cache_worker().

2019-11-25Merge branch 'ib-guids' into rdma.git for-nextJason Gunthorpe
Danit Goldberg says: ==================== This series extends RTNETLINK to provide IB port and node GUIDs, which were configured for Infiniband VFs. The functionality to set VF GUIDs already existed for a long time, and here we are adding the missing "get" so that netlink will be symmetric and various cloud orchestration tools will be able to manage such VFs more naturally. The iproute2 was extended too to present those GUIDs. - ip link show <device> For example: - ip link set ib4 vf 0 node_guid 22:44:33:00:33:11:00:33 - ip link set ib4 vf 0 port_guid 10:21:33:12:00:11:22:10 - ip link show ib4 ib4: <BROADCAST,MULTICAST> mtu 4092 qdisc noop state DOWN mode DEFAULT group default qlen 256 link/infiniband 00:00:0a:2d:fe:80:00:00:00:00:00:00:ec:0d:9a:03:00:44:36:8d brd 00:ff:ff:ff:ff:12:40:1b:ff:ff:00:00:00:00:00:00:ff:ff:ff:ff vf 0 link/infiniband 00:00:0a:2d:fe:80:00:00:00:00:00:00:ec:0d:9a:03:00:44:36:8d brd 00:ff:ff:ff:ff:12:40:1b:ff:ff:00:00:00:00:00:00:ff:ff:ff:ff, spoof checking off, NODE_GUID 22:44:33:00:33:11:00:33, PORT_GUID 10:21:33:12:00:11:22:10, link-state disable, trust off, query_rss off ==================== Based on the mlx5-next branch from git://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux for dependencies * branch 'ib-guids': (35 commits) IB/mlx5: Implement callbacks for getting VFs GUID attributes IB/ipoib: Add ndo operation for getting VFs GUID attributes IB/core: Add interfaces to get VF node and port GUIDs net/core: Add support for getting VF GUIDs net/mlx5: Add new chain for netfilter flow table offload net/mlx5: Refactor creating fast path prio chains net/mlx5: Accumulate levels for chains prio namespaces net/mlx5: Define fdb tc levels per prio net/mlx5: Rename FDB_* tc related defines to FDB_TC_* defines net/mlx5: Simplify fdb chain and prio eswitch defines IB/mlx5: Load profile according to RoCE enablement state IB/mlx5: Rename profile and init methods net/mlx5: Handle "enable_roce" devlink param net/mlx5: Document flow_steering_mode devlink param devlink: Add new "enable_roce" generic device param net/mlx5: fix spelling mistake "metdata" -> "metadata" net/mlx5: fix kvfree of uninitialized pointer spec IB/mlx5: Introduce and use mlx5_core_is_vf() net/mlx5: E-switch, Enable metadata on own vport net/mlx5: Refactor ingress acl configuration ...

2019-11-25scripts/kallsyms: add sym_name() to mitigate cast uglinessMasahiro Yamada
sym_entry::sym is (unsigned char *) instead of (char *) because kallsyms exploits the MSB for compression, and the characters are used as the index of token_profit array. However, it requires casting (unsigned char *) to (char *) in some places since standard library functions such as strcmp(), strlen() expect (char *). Introduce a new helper, sym_name(), which advances the given pointer by 1 and casts it to (char *). Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

2019-11-25scripts/kallsyms: set relative_base more effectivelyMasahiro Yamada
Currently, record_relative_base() iterates over the entire table to find the minimum address, but it is not efficient because we sort the table anyway. After sort_symbol(), the table is sorted by address. (kallsyms parses the 'nm -n' output, so the data is already sorted by address, but this commit does not rely on it.) Move record_relative_base() after sort_symbols(), and take the first non-absolute symbol value. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
