ell-key-crypto kernel branch updated for v4.9
by Mat Martineau
Hello -
There's an updated ell-key-crypto branch on git.kernel.org:
https://git.kernel.org/cgit/linux/kernel/git/martineau/linux.git/
This is based on v4.9-rc5 of the kernel and includes:
* My keyctl restricted keyring patch set
* linux-fs/keys-blacklist (as a basis for upstreaming)
* linux-fs/keys-next (for keyctl crypto ops)
* A revert commit for an AF_ALG hash commit that caused a kernel crash
when ELL's unit/test-checksum was run
The nl80211 patches I had been carrying for iwd are part of v4.9.
The previous v4.8 key crypto kernel is tagged as ell-key-crypto-48
Relative to my Fedora 24 kernel 4.8 config, the following commands will
enable the required config options:
$ cp /boot/config-<recent kernel-version> .config
$ scripts/config --enable CONFIG_PKCS8_PRIVATE_KEY_PARSER
$ make olddefconfig

[PATCH] dbus: Don't send replies to messages with no reply flag
by Andrew Zaborowski
Kdbus doesn't store the cookies for messages that have the no reply flag
and throws error when a reply is sent with reply_cookie that it doesn't
know. It's not fatal, but we save some cycles by not sending the message
with both dbus versions.
We mark those replies with reply_serial == 0, rather than setting a
"discard" flag on the message, because the method call's serial is
effectively an invalid reply_serial value.

[PATCH 1/5] string: Add l_string_unwrap and simplify l_string_free
by Mat Martineau
This removes the "free a string object but return the internal data"
functionality of l_string_free. The option to not free everything was a
source of confusion.
l_string_unwrap is the same as the old l_string_free(ptr, false).
