2024-08-03tools: hv: lsvmbus: change shebang to use python3Anthony Nandaa1-1/+1
In many modern Linux distros, running `lsvmbus` returns the error: ``` /usr/bin/env: 'python': No such file or directory ``` because 'python' doesn't point anywhere. Now that python2 has reached EOL as of January 1, 2020 and is no longer maintained[1], these distros have python3 instead. Also, the script isn't executable by default because the permissions are set to mode 644. Fix this by updating the shebang in the `lsvmbus` to use python3 instead of python. Also fix the permissions to be 755 so that is executable by default, which matches other similar scripts in `tools/hv`. The script is also tested and verified that is compatible with python3.

2023-10-10hv/hv_kvp_daemon:Support for keyfile based connection profileShradha Gupta2-37/+235
Ifcfg config file support in NetworkManger is deprecated. This patch provides support for the new keyfile config format for connection profiles in NetworkManager. The patch modifies the hv_kvp_daemon code to generate the new network configuration in keyfile format(.ini-style format) along with a ifcfg format configuration. The ifcfg format configuration is also retained to support easy backward compatibility for distro vendors. These configurations are stored in temp files which are further translated using the hv_set_ifconfig.sh script. This script is implemented by individual distros based on the network management commands supported. For example, RHEL's implementation could be found here: https://gitlab.com/redhat/centos-stream/src/hyperv-daemons/-/blob/c9s/hv_set_ifconfig.sh Debian's implementation could be found here: https://github.com/endlessm/linux/blob/master/debian/cloud-tools/hv_set_ifconfig The next part of this support is to let the Distro vendors consume these modified implementations to the new configuration format.

Covert as follows: $(if A,A,B) --> $(or A,B) This patch also converts: $(if A, A, B) --> $(or A, B) Strictly speaking, the latter is not an equivalent conversion because GNU Make keeps spaces after commas; if A is not empty, $(if A, A, B) expands to " A", while $(or A, B) expands to "A".

2020-01-26Tools: hv: Reopen the devices if read() or write() returns errorsDexuan Cui3-31/+91
The state machine in the hv_utils driver can run out of order in some corner cases, e.g. if the kvp daemon doesn't call write() fast enough due to some reason, kvp_timeout_func() can run first and move the state to HVUTIL_READY; next, when kvp_on_msg() is called it returns -EINVAL since kvp_transaction.state is smaller than HVUTIL_USERSPACE_REQ; later, the daemon's write() gets an error -EINVAL, and the daemon will exit(). We can reproduce the issue by sending a SIGSTOP signal to the daemon, wait for 1 minute, and send a SIGCONT signal to the daemon: the daemon will exit() quickly. We can fix the issue by forcing a reset of the device (which means the daemon can close() and open() the device again) and doing extra necessary clean-up.

Commit ea81fdf0981d ("Tools: hv: vss: Skip freezing filesystems backed by loop") added skip for filesystems backed by loop device. However, it seems the detection of such cases is incomplete. It was found that with 'devicemapper' storage driver docker creates the following chain: NAME MAJ:MIN loop0 7:0 ..docker-8:4-8473394-pool 253:0 ..docker-8:4-8473394-eac... 253:1 so when we're looking at the mounted device we see major '253' and not '7'. Solve the issue by walking /sys/dev/block/*/slaves chain and checking if there's a loop device somewhere. Other than that, don't skip mountpoints silently when stat() fails. In case e.g. SELinux is failing stat we don't want to skip freezing everything without letting user know about the failure.

The existing KVP daemon only gets IP from the first NIC matching a MAC address, and may not be able to find the IP in this case.

2018-02-21tools: fix cross-compile var clobberingMartin Kelly1-1/+0
Currently a number of Makefiles break when used with toolchains that pass extra flags in CC and other cross-compile related variables (such as --sysroot). Thus we get this error when we use a toolchain that puts --sysroot in the CC var: ~/src/linux/tools$ make iio [snip] iio_event_monitor.c:18:10: fatal error: unistd.h: No such file or directory #include <unistd.h> ^~~~~~~~~~ This occurs because we clobber several env vars related to cross-compiling with lines like this: CC = $(CROSS_COMPILE)gcc Although this will point to a valid cross-compiler, we lose any extra flags that might exist in the CC variable, which can break toolchains that rely on them (for example, those that use --sysroot).

Normally with the --sysroot flag we would find unistd.h in the sdk directory in the sysroot: $ find [snip]/sdk/sysroots -path '*/usr/include/unistd.h' [snip]/sdk/sysroots/cortexa8hf-neon-poky-linux-gnueabi/usr/include/unistd.h The perf Makefile adds CC = $(CROSS_COMPILE)gcc if and only if CC is not already set, and it compiles correctly with the above toolchain. So, generalize the logic that perf uses in the common Makefile and remove the manual CC = $(CROSS_COMPILE)gcc lines from each Makefile. Note that this patch does not fix cross-compile for all the tools (some have other bugs), but it does fix it for all except usb and acpi, which still have other unrelated issues. I tested both with and without the patch on native and cross-build and there appear to be no regressions.

2017-11-28hv: kvp: Avoid reading past allocated blocks from KVP filePaul Meyer1-56/+14
While reading in more than one block (50) of KVP records, the allocation goes per block, but the reads used the total number of allocated records (without resetting the pointer/stream). This causes the records buffer to overrun when the refresh reads more than one block over the previous capacity (e.g. reading more than 100 KVP records whereas the in-memory database was empty before). Fix this by reading the correct number of KVP records from file each time.

2017-11-02License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseGreg Kroah-Hartman4-0/+4
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.

2017-08-16Tools: hv: vss: Skip freezing filesystems backed by loopAlex Ng1-0/+7
Since a loop device is backed by a file, a backup will already result in its parent filesystem being frozen. It's sufficient to just freeze the parent filesystem, so we can skip the loop device. This avoids a situation where a loop device and its parent filesystem are both frozen and then thawed out of order. For example, if the loop device is enumerated first, we would thaw it while its parent filesystem is still frozen. The thaw operation fails and the loop device remains frozen.
