Kernel 2.6.32-573.el6, released 2015-07-22 as part of RHEL 6.7, supports cap_last_cap file, so there is no need for a workaround. Signed-off-by: Kir Kolyshkin <kolyshkin@gmail.com>
sync.OnceValues is available since Go 1.21 and allows to have less global variables when using sync.Once. Signed-off-by: Kir Kolyshkin <kolyshkin@gmail.com>
slices.Sort was introduced in Go 1.21. As the code already imports slices, using slices.Sort allows to have one less package imported. Signed-off-by: Kir Kolyshkin <kolyshkin@gmail.com>
Replace init and the two global variables with two functions, capList and capStrList, wrapped in sync.OnceValues. This way, there is no runtime overhead of merely including this package, as these functions are executed as needed, not during program initialization. While at it: - rename getCapName to capName for brewity; - use slices.DeleteFunc in capList to filter the slice in place instead of making a copy (less garbage to collect); - improve AllCapabilities documentation. Note that currently neither function returns an error; this is a preparation for the next patch. Signed-off-by: Kir Kolyshkin <kolyshkin@gmail.com>
