73fc0cbc87 fd-util: export get_max_fd() so that we can use it in tests 2021-10-27 17:56:36 +02:00

ab27b2fe56 exec-util: use close_all_fds_without_malloc() from freeze() 2021-10-27 17:56:36 +02:00

5cfa0798ba fd-util: split out close_all_fds() special case handling and call it from close_all_fds_without_malloc(), too 
The optimization is useful there too.

1f6639eac7 fd-util: close_all() check d_type 
Tiny optimization: check dirent's d_type before trying to parse
/proc/self/fd/ filenames, given we have that anyway.

c844f0a924 fd-util: always return 0 on success in close_all_fds() 
We never make use of the return value, and in case of close_range() we
don't even know how many fds got closed, hence don't pretend we knew.

f498720a34 fd-util: special case invocation of close_all_fds() with single exception fd 
Add special case optimization for a single exception fd. It's a
pretty common case in our codebase, and the optimization is simple
and means we don't need to copy/sort the exception array, so do it.

6663b509d8 bootctl: refuse parsing unknown special '@' entry ids 
Let's make sure '@' is never written as entry ID into any EFI variable,
as we want the ability to add new ids like this later on, with them
resulting in a clear error on older implementations.

cfee6b9551 change indicator used for later versions of VirtualBox (#21127) 
Detection of VirtualBox is accomplished in the existing code by *either* `innotek GmbH`
or `Oracle Corporation` existing in any of:

- /sys/class/dmi/id/product_name
- /sys/class/dmi/id/sys_vendor
- /sys/class/dmi/id/board_vendor
- /sys/class/dmi/id/bios_vendor

With Oracle's physical servers, both `/sys/class/dmi/id/sys_vendor` and
`/sys/class/dmi/id/board_vendor` contain `Oracle Corporation`, so those
servers are detected as `oracle` (VirtualBox).

VirtualBox has the following values in the latest versions:

- /sys/class/dmi/id/product_name: `VirtualBox`
- /sys/class/dmi/id/sys_vendor: `innotek GmbH`
- /sys/class/dmi/id/board_vendor: `Oracle Corporation`
- /sys/class/dmi/id/bios_vendor: `innotek GmbH`

Presumably the existing check for `innotek GmbH` is meant to detect
older versions of VirtualBox, while changing the second checked value
from `Oracle Corporation` to `VirtualBox` will reliably detect later and future
versions.

8f1daefce6 json: do something remotely reasonable when we see NaN/infinity 
JSON doesn't have NaN/infinity/-infinity concepts in the spec.
Implementations vary what they do with it. JSON5 + Python simply
generate special words "NAN" and "Inifinity" from it. Others generate
"null" for it.

At this point we never actually want to output this, so let's be
conservative and generate RFC compliant JSON, i.e. convert to null.

One day should JSON5 actually become a thing we can revisit this, but in
that case we should implement things via a flag, and only optinally
process nan/infinity/-infinity.

This patch is extremely simple: whenever accepting a
nan/infinity/-infinity from outside it converts it to NULL. I.e. we
convert on input, not output.

079f94edfa network: dhcp6: do not reconfigure/restart DHCPv6 clients when a new downstream appears 
Previously, when a downstream appears which requests delegated prefix to
be assigned, then possibly restart all DHCPv6 clients for another
interfaces.

This makes networkd always honor the UseDelegatedPrefix= setting, and
not restart DHCPv6 clients.
