| * | | | docs: ABI: vdso: use the right format for ABIMauro Carvalho Chehab2020-10-301-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This ABI is not following the format described at ABI/README. Use it, filling in the blanks with the git log that added it, and using the current e-mail from Andy.

| * | | | docs: ABI: fix syntax to be parsed using ReST notationMauro Carvalho Chehab2020-10-3017-161/+271
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are a number of new changes at the ABI files that cause them to produce warnings when generating ABI output. Fix them.

Allow checking if they're following the syntax by running the ABI parser script on COMPILE_TEST. With that, when there's a problem with a file under Documentation/ABI, it would produce a warning like: Warning: file ./Documentation/ABI/testing/sysfs-bus-pci-devices-aer_stats#14: What '/sys/bus/pci/devices/<dev>/aer_stats/aer_rootport_total_err_cor' doesn't have a description Warning: file ./Documentation/ABI/testing/sysfs-bus-pci-devices-aer_stats#21: What '/sys/bus/pci/devices/<dev>/aer_stats/aer_rootport_total_err_fatal' doesn't have a description Acked-by: Jonathan Corbet <corbet@lwn.net> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org> Link: https://lore.kernel.org/r/57a38de85cb4b548857207cf1fc1bf1ee08613c9.1604042072.git.mchehab+huawei@kernel.org Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

The workaround requires a DMB SY before and after a PAR_EL1 register read. In addition, it's possible an interrupt (doing a device read) or KVM guest exit could be taken between the DMB and PAR read, so we also need a DMB before returning from interrupt and before returning to a guest. A deadlock is still possible with the workaround as KVM guests must also have the workaround. IOW, a malicious guest can deadlock an affected systems. This workaround also depends on a firmware counterpart to enable the h/w to insert DMB SY after load and store exclusive instructions. See the errata document SDEN-1152370 v10 [1] for more information.

This has the side-effect that the uaccess routines will not honour the PSTATE.TCO that may have been set by the user prior to a syscall. There is no issue in practice since PSTATE.TCO is expected to be used only for brief periods in specific routines (e.g. garbage collection). To control the tag checking mode of the uaccess routines, the user will have to invoke a corresponding prctl() call. Document the kernel behaviour w.r.t. PSTATE.TCO accordingly.

The same command may be successful if retried later, but the host needs to wait for specific zone states before it should expect a retry to succeed. Have the block layer provide an appropriate status for these conditions so applications can distinuguish this error for special handling.
