2020-03-11IB/hfi1, qib: Ensure RCU is locked when accessing listDennis Dalessandro
commit 817a68a6584aa08e323c64283fec5ded7be84759 upstream. The packet handling function, specifically the iteration of the qp list for mad packet processing misses locking RCU before running through the list. Not only is this incorrect, but the list_for_each_entry_rcu() call can not be called with a conditional check for lock dependency. Remedy this by invoking the rcu lock and unlock around the critical section. This brings MAD packet processing in line with what is done for non-MAD packets.

2019-12-17RDMA/qib: Validate ->show()/store() callbacks before calling themViresh Kumar
commit 7ee23491b39259ae83899dd93b2a29ef0f22f0a7 upstream. The permissions of the read-only or write-only sysfs files can be changed (as root) and the user can then try to read a write-only file or write to a read-only file which will lead to kernel crash here. Protect against that by always validating the show/store callbacks.

[ Upstream commit 904bba211acc2112fdf866e5a2bc6cd9ecd0de1b ] The work completion length for a receiving a UD send with immediate is short by 4 bytes causing application using this opcode to fail. The UD receive logic incorrectly subtracts 4 bytes for immediate value. These bytes are already included in header length and are used to calculate header/payload split, so the result is these 4 bytes are subtracted twice, once when the header length subtracted from the overall length and once again in the UD opcode specific path. Remove the extra subtraction when handling the opcode. Fixes: 7724105686e7 ("IB/hfi1: add driver files") Reviewed-by: Michael J.

commit 09ce351dff8e7636af0beb72cd4a86c3904a0500 upstream. Fix potential memory corruption and panic in loopback for IB_WR_SEND variants. The code blindly assumes the posted length will fit in the fetched rwqe, which is not a valid assumption. Fix by adding a limit test, and triggering the appropriate send completion and putting the QP in an error state. This mimics the handling for non-loopback QPs.

2017-11-02License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseGreg Kroah-Hartman
Many source files in the tree are missing licensing information, which makes it harder for compliance tools to determine the correct license. By default all files without license information are under the default license of the kernel, which is GPL version 2. Update the files which contain no license information with the 'GPL-2.0' SPDX license identifier. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. How this work was done: Patches were generated and checked against linux-4.14-rc6 for a subset of the use cases: - file had no licensing information it it. - file was a */uapi/* one with no licensing information in it, - file was a */uapi/* one with existing licensing information, Further patches will be generated in subsequent months to fix up cases where non-standard license headers were used, and references to license had to be inferred by heuristics based on keywords. The analysis to determine which SPDX License Identifier to be applied to a file was done in a spreadsheet of side by side results from of the output of two independent scanners (ScanCode & Windriver) producing SPDX tag:value files created by Philippe Ombredanne. Philippe prepared the base worksheet, and did an initial spot review of a few 1000 files. The 4.13 kernel was the starting point of the analysis with 60,537 files assessed. Kate Stewart did a file by file comparison of the scanner results in the spreadsheet to determine which SPDX license identifier(s) to be applied to the file. She confirmed any determination that was not immediately clear with lawyers working with the Linux Foundation. Criteria used to select files for SPDX license identifier tagging was: - Files considered eligible had to be source code files. - Make and config files were included as candidates if they contained >5 lines of source - File already had some variant of a license header in it (even if <5 lines). All documentation files were explicitly excluded. The following heuristics were used to determine which SPDX license identifiers to apply. - when both scanners couldn't find any license traces, file was considered to have no license information in it, and the top level COPYING file license applied. For non */uapi/* files that summary was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 11139 and resulted in the first patch in this series. If that file was a */uapi/* path one, it was "GPL-2.0 WITH Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 WITH Linux-syscall-note 930 and resulted in the second patch in this series. - if a file had some form of licensing information in it, and was one of the */uapi/* ones, it was denoted with the Linux-syscall-note if any GPL family license was found in the file or had no licensing in it (per prior point). Results summary: SPDX license identifier # files ---------------------------------------------------|------ GPL-2.0 WITH Linux-syscall-note 270 GPL-2.0+ WITH Linux-syscall-note 169 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17 LGPL-2.1+ WITH Linux-syscall-note 15 GPL-1.0+ WITH Linux-syscall-note 14 ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5 LGPL-2.0+ WITH Linux-syscall-note 4 LGPL-2.1 WITH Linux-syscall-note 3 ((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3 ((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1 and that resulted in the third patch in this series. - when the two scanners agreed on the detected license(s), that became the concluded license(s). - when there was disagreement between the two scanners (one detected a license but the other didn't, or they both detected different licenses) a manual inspection of the file occurred. - In most cases a manual inspection of the information in the file resulted in a clear resolution of the license that should apply (and which scanner probably needed to revisit its heuristics). - When it was not immediately clear, the license identifier was confirmed with lawyers working with the Linux Foundation. - If there was any question as to the appropriate license identifier, the file was flagged for further research and to be revisited later in time. In total, over 70 hours of logged manual review was done on the spreadsheet to determine the SPDX license identifiers to apply to the source files by Kate, Philippe, Thomas and, in some cases, confirmation by lawyers working with the Linux Foundation. Kate also obtained a third independent scan of the 4.13 code base from FOSSology, and compared selected files where the other two scanners disagreed against that SPDX file, to see if there was new insights. The Windriver scanner is based on an older version of FOSSology in part, so they are related. Thomas did random spot checks in about 500 files from the spreadsheets for the uapi headers and agreed with SPDX license identifier in the files he inspected. For the non-uapi files Thomas did random spot checks in about 15000 files. In initial set of patches against 4.14-rc6, 3 files were found to have copy/paste license identifier errors, and have been fixed to reflect the correct identifier. Additionally Philippe spent 10 hours this week doing a detailed manual inspection and review of the 12,461 patched files from the initial patch version early this week with: - a full scancode scan run, collecting the matched texts, detected license ids and scores - reviewing anything where there was a license detected (about 500+ files) to ensure that the applied SPDX license was correct - reviewing anything where there was no detection but the patch license was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied SPDX license was correct This produced a worksheet with 20 files needing minor correction. This worksheet was then exported into 3 different .csv files for the different types of files to be modified. These .csv files were then reviewed by Greg. Thomas wrote a script to parse the csv files and add the proper SPDX tag to the file, in the format that the file expected. This script was further refined by Greg based on the output to detect more types of files automatically and to distinguish between header and source .c files (which need different comment types.) Finally Greg ran the script using the .csv files to generate the patches.

The following situation will result in a QP hang: - A prior SEND or RDMA_WRITE with immmediate consumed the last credit for a QP using RC receive buffer credits - The prior op is acked so there are no more acks - The peer ULP fails to post receive for some reason - An RDMA write sees that the credits are exhausted and waits - The peer ULP posts receive buffers - The ULP posts a send or RDMA write that will be hung The fix is to avoid the credit test for the RDMA write operation.

2017-06-27IB/rdmavt: Compress adjacent SGEs in rvt_lkey_ok()Mike Marciniszyn
SGEs that are contiguous needlessly consume driver dependent TX resources. The lkey validation logic is enhanced to compress the SGE that ends up in the send wqe when consecutive addresses are detected. The lkey validation API used to return 1 (success) or 0 (fail). The return value is now an -errno, 0 (compressed), or 1 (uncompressed). A additional argument is added to pass the last SQE for the compression. Loopback callers always pass a NULL to last_sge since the optimization is of little benefit in that situation.

2017-06-01RDMA/qib,hfi1: Fix MR reference count leak on write with immediateMike Marciniszyn
The handling of IB_RDMA_WRITE_ONLY_WITH_IMMEDIATE will leak a memory reference when a buffer cannot be allocated for returning the immediate data. The issue is that the rkey validation has already occurred and the RNR nak fails to release the reference that was fruitlessly gotten. The the peer will send the identical single packet request when its RNR timer pops. The fix is to release the held reference prior to the rnr nak exit. This is the only sequence the requires both rkey validation and the buffer allocation on the same packet.

2017-02-19IB/rdmavt, IB/hfi1, IB/qib: Correct ack count for passive (RTR) QPsMike Marciniszyn
The send complete for RC QPs mismanages the ack count when the responder side is only in RTR. A QP in that state cannot send requests, but it can be the target for operations that elicit responses. Adjust the RC completion logic to correct the count maintenance by reflecting RECV_OK in a new state test.
