dynld - load kernel module dynamically


bind -a #L /dev



Dynld serves a directory containing two files that control dynamic loading of modules. When a module is loaded, dynld(10.2)), checks the module's type against a type provided by the driver; the types must match. Currently the only supported module type is that of a device driver, Dev defined in dev(10.2)).

The control file dynld can only be opened by the host owner (see eve(10.2)). It accepts the following commands:

load dev name file [ [ tag ] dep ... ]
Load a module for device driver name from the given file. The optional tag is typically the MD5 or SHA1 hash of the file's contents, to identify a particular version of the driver.
unload dev name [ file [ tag ] ]
Unload the device driver identified by the given name, optionally qualified by the other parameters.

When read, dynld returns a list of the currently-loaded drivers, one per line, most recent first. Each line contain: the module's device type #x used in bind(1); its kernel address; its total text and data size in bytes; its name when loaded; the name of the file from which it was loaded; and its tag.

Dynsyms is a read-only text file that lists, one per line, the symbols exported by the running kernel for use by modules it loads. Each line contains: the symbol's kernel address, its type signature, and its name.




dynld(10.2), a.out(10.6),


Dynld does not currently check that a driver is no longer in use before unloading it.
