kmod 30
|
||||
=======
|
||||
|
||||
- Improvements
|
||||
- Stop adding duplicate information on modules.builtin.alias.bin, just use
|
||||
the modules.builtin.bin index
|
||||
|
||||
- Speedup depmod, particularly under qemu with emulated arch, by
|
||||
avoiding a lot of open/read/close of modules.alias.bin. On an
|
||||
emulated ARM rootfs, depmod with only 2 modules was taking ~32s
|
||||
vs ~0.07s now.
|
||||
|
||||
- Add kmod_module_new_from_name_lookup() which allows doing a lookup by
|
||||
module name, without considering the aliases. Other than that search
|
||||
order is similar to kmod_module_new_from_lookup().
|
||||
|
||||
- modinfo learned the --modname option to explicitely show information
|
||||
about the module, even if there is an alias with the same name. This
|
||||
allows showing information about e.g. kernel/lib/crc32.ko, even if
|
||||
kernel also exports a crc32 alias in modules.alias:
|
||||
|
||||
alias crc32 crc32_pclmul
|
||||
alias crc32 crc32_generic
|
||||
|
||||
Same behavior will be used to other modules and to aliases provided
|
||||
by user/distro.
|
||||
|
||||
- depmod.conf learned a new "excludedir" directive so distro/user can
|
||||
configure more directories to be excluded from its search, besides
|
||||
the hardcoded values "build" and "source".
|
||||
|
||||
- Better group modprobe options on help output under "Management, Query and General".
|
||||
|
||||
- modprobe learned a --wait <MSEC> option to be used together with -r
|
||||
when removing a module. This allows modprobe to keep trying the
|
||||
removal if it fails because the module is still in use. An exponential backoff
|
||||
time is used for further retries.
|
||||
|
||||
The wait behavior provided by the kernel when not passing O_NONBLOCK
|
||||
to delete_module() was removed in v3.13 due to not be used and the
|
||||
consequences of having to support it in the kernel. However there may
|
||||
be some users, particularly on testsuites for individual susbsystems, that
|
||||
would want that. So provide a userspace implementation inside modprobe for
|
||||
such users. "rmmod" doesn't have a --wait as it remains a bare minimal over
|
||||
the API provided by the kernel. In future the --wait behavior can be added
|
||||
to libkmod for testsuites not exec'ing modprobe for module removal.
|
||||
|
||||
- kmod_module_remove_module() learned a new flag to silence output when
|
||||
caller wants to handle them - this is particularly important for the
|
||||
--wait flag to modprobe, as it's not desired to keep seeing error messages
|
||||
while waiting for the module to be unused.
|
||||
|
||||
- Add SM3 hash algo support to modinfo output, as already available in the kernel.
|
||||
|
||||
- Bug Fixes
|
||||
- Fix modinfo output when showing information for a .ko module when running
|
||||
on a kernel that has that module as builtin.
|
||||
|
||||
- Fix kmod_module_new_from_lookup() returning > 0 rather than 0
|
||||
when it matches an alias.
|
||||
|
||||
- Fix modinfo segfault when module doesn't exist.
|
||||
|
||||
- Add missing function in the html documentation: kmod_get_dirname().
|
||||
|
||||
- Fix modprobe incorrectly handling number of arguments when prepending values from
|
||||
MODPROBE_OPTIONS environment variable.
|
||||
|
||||
- Fix modprobe -r --remove-dependencies and since "dependencies" was a
|
||||
misnomer, add the preferred argument option: "--remove-holders". This
|
||||
is the same name used by the kernel. It allows users to also remove
|
||||
other modules holding the one that is being removed.
|
||||
|
||||
- Fix off-by-one in max module name length in depmod.
|
||||
|
||||
- Infra/internal
|
||||
- Start some changes in the out-of-tree test modules in kmod so they are useful
|
||||
for being really inserted in the kernel rather than relying on kmod's mock
|
||||
interface. This helps manual testing and may be used to exercise to test
|
||||
changes in the kernel.
