pkey_alloc and the other pkey system calls are not implemented in valgrind: --64-- WARNING: unhandled amd64-linux syscall: 329 --64-- You may be able to write your own handler. --64-- Read the file README_MISSING_SYSCALL_OR_IOCTL. --64-- Nevertheless we consider this a bug. Please report --64-- it at http://valgrind.org/support/bug_reports.html. pkey_mprotect should be treated as mprotect with an extra argument (in which all bits are significant). For pkey_alloc and pkey_free, all bits in the arguments are significant. No special treatment is needed for them. On Intel, PKRU reads and writes need to be implemented as well. These instructions should be passed through to the host, after checking (for WRPKRU) that all bits are defined.
The Intel machines in Beaker can be found by hunting for the “pkru” flag. POWER has support as well (but you need 4.17 kernel or later, with upcoming fixes). The system calls are the same for POWER, and POWER8 machines have the necessary hardware support (unless they run under PowerKVM, but LPARs are fine). The PKRU register on POWER is called AMR.
This bug appears to have been reported against 'rawhide' during the Fedora 29 development cycle. Changing version to '29'.
This message is a reminder that Fedora 29 is nearing its end of life. Fedora will stop maintaining and issuing updates for Fedora 29 on 2019-11-26. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '29'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 29 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 29 changed to end-of-life (EOL) status on 2019-11-26. Fedora 29 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
