* ps(1): Fix formatting of the "command" field for kernel threads.Mark Johnston2020-07-281-4/+7
| | | | | | | | | | | | | | | | | | When -H is specified, for kernel threads the command is formatted as "<proc name>/<td name>" and truncated to MAXCOMLEN. But each of the proc name and td name may be up to MAXCOMLEN bytes in length. Also handle the ki_moretdname field to ensure that the full thread name gets printed. This is already handled correctly when formatting for "-o tdname".

* Add a workaround for a bug when setting the Raspberry GIO config and stateAndrew Turner2020-07-281-0/+11
| | | | | | | | | | | | The Raspberry Pi GPIO config and state messages incorrectly return with the tag length set to 0. We then check this value to have the response flag set. Work around this by setting the response flag when setting the GPIO config or state and this value is zero. Sponsored by: Innovate UK Notes: svn path=/head/; revision=363647

| | | | | | | | | | | | | | | | PowerPC support was fixed in r357596 by changing PCI bustag to BE as part of the solution, but this caused regression on mips. This change implements byte swapping of virtio PCI config area in the driver, leaving lower layer untouched.

* ssh: Remove AES-CBC ciphers from default server and client listsEd Maste2020-07-283-12/+2
| | | | | | | | | | | | | | | | | | | | | A base system OpenSSH update in 2016 or so removed a number of ciphers from the default lists offered by the server/client, due to known weaknesses. This caused POLA issues for some users and prompted PR207679; the ciphers were restored to the default lists in r296634. When upstream removed these ciphers from the default server list, they moved them to the client-only default list. They were subsequently removed from the client default, in OpenSSH 7.9p1. The change has persisted long enough. Remove these extra ciphers from both the server and client default lists, in advance of FreeBSD 13.

* Add initial driver for ACPI Platform Error Interfaces.Alexander Motin2020-07-279-0/+788
| | | | | | | | | | | | | | | | | | | | | | | | | APEI allows platform to report different kinds of errors to OS in several ways. We've found that Supermicro X10/X11 motherboards report PCIe errors appearing on hot-unplug via this interface using NMI. Without respective driver it ended up in kernel panic without any additional information. This driver introduces support for the APEI Generic Hardware Error Source reporting via NMI, SCI or polling. It decodes the reported errors and either pass them to pci(4) for processing or just logs otherwise. Errors marked as fatal still end up in kernel panic, but some more informative. When somebody get to native PCIe AER support implementation both of the reporting mechanisms should get common error recovery code. Since in our case errors happen when the device is already gone, there is nothing to recover, so the code just clears the error statuses, practically ignoring the otherwise destructive NMIs in nicer way.

Worse, since the kernel's array could theoretically change size over time, any use of that symbol in userland wouldn't be forwards compatible to new kernel versions.

* Fix the NFS server so that it sets va_birthtime.Rick Macklem2020-07-261-2/+6
| | | | | | | | | | | | | | | | | | | | r362490 marked that the NFSv4 attribute TimeCreate (va_birthtime) is supported, but it did not change the NFS server code to actually do it. As such, errors could occur when unrolling a tarball onto an NFSv4 mounted volume, since setting TimeCreate would fail with a NFSERR_ATTRNOTSUPP reply. This patch fixes the server so that it does TimeCreate and also makes sure that TimeCreate will not be set for a DS file for a pNFS server. A separate commit will add a check to the NFSv4 client for support of the TimeCreate attribute before attempting to set it, to avoid a problem when mounting a server that does not support the attribute. The failures will still occur for r362490 or later kernels that do not have this patch, since they indicate support for the attribute, but do not actually support the attribute.
