12) The canonical patch format
12) More references for submitting patches
The canonical patch subject line is:
Subject: [PATCH 001/123] subsystem: summary phrase
The canonical patch message body contains the following:
- A "from" line specifying the patch author.
- An empty line.
- The body of the explanation, which will be copied to the
permanent changelog to describe this patch.
- The "Signed-off-by:" lines, described above, which will
also go in the changelog.
- A marker line containing simply "---".
- Any additional comments not suitable for the changelog.
- The actual patch (diff output).
The Subject line format makes it very easy to sort the emails
alphabetically by subject line - pretty much any email reader will
support that - since because the sequence number is zero-padded,
the numerical and alphabetic sort is the same.
The "subsystem" in the email's Subject should identify which
area or subsystem of the kernel is being patched.
The "summary phrase" in the email's Subject should concisely
describe the patch which that email contains. The "summary
phrase" should not be a filename. Do not use the same "summary
phrase" for every patch in a whole patch series.
Bear in mind that the "summary phrase" of your email becomes
a globally-unique identifier for that patch. It propagates
all the way into the git changelog. The "summary phrase" may
later be used in developer discussions which refer to the patch.
People will want to google for the "summary phrase" to read
discussion regarding that patch.
A couple of example Subjects:
Subject: [patch 2/5] ext2: improve scalability of bitmap searching
Subject: [PATCHv2 001/207] x86: fix eflags tracking
The "from" line must be the very first line in the message body,
and has the form:
From: Original Author <author@example.com>
The "from" line specifies who will be credited as the author of the
patch in the permanent changelog. If the "from" line is missing,
then the "From:" line from the email header will be used to determine
the patch author in the changelog.
The explanation body will be committed to the permanent source
changelog, so should make sense to a competent reader who has long
since forgotten the immediate details of the discussion that might
have led to this patch.
The "---" marker line serves the essential purpose of marking for patch
handling tools where the changelog message ends.
One good use for the additional comments after the "---" marker is for
a diffstat, to show what files have changed, and the number of inserted
and deleted lines per file. A diffstat is especially useful on bigger
patches. Other comments relevant only to the moment or the maintainer,
not suitable for the permanent changelog, should also go here.

Userspace usage.
/*****************************************/
2.6.14 has a new netlink socket implementation, which by default does not
allow to send data to netlink groups other than 1.
So, if to use netlink socket (for example using connector)
with different group number userspace application must subscribe to
that group. It can be achieved by following pseudocode:
s = socket(PF_NETLINK, SOCK_DGRAM, NETLINK_CONNECTOR);
l_local.nl_family = AF_NETLINK;
l_local.nl_groups = 12345;
l_local.nl_pid = 0;
if (bind(s, (struct sockaddr *)&l_local, sizeof(struct sockaddr_nl)) == -1) {
perror("bind");
close(s);
return -1;
}
{
int on = l_local.nl_groups;
setsockopt(s, 270, 1, &on, sizeof(on));
}
Where 270 above is SOL_NETLINK, and 1 is a NETLINK_ADD_MEMBERSHIP socket
option. To drop multicast subscription one should call above socket option
with NETLINK_DROP_MEMBERSHIP parameter which is defined as 0.
2.6.14 netlink code only allows to select a group which is less or equal to
the maximum group number, which is used at netlink_kernel_create() time.
In case of connector it is CN_NETLINK_USERS + 0xf, so if you want to use
group number 12345, you must increment CN_NETLINK_USERS to that number.
Additional 0xf numbers are allocated to be used by non-in-kernel users.
Due to this limitation, group 0xffffffff does not work now, so one can
not use add/remove connector's group notifications, but as far as I know,
only cn_test.c test module used it.
Some work in netlink area is still being done, so things can be changed in
2.6.15 timeframe, if it will happen, documentation will be updated for that
kernel.

===================
KEY REQUEST SERVICE
===================
The key request service is part of the key retention service (refer to
Documentation/keys.txt). This document explains more fully how that the
requesting algorithm works.
The process starts by either the kernel requesting a service by calling
request_key():
struct key *request_key(const struct key_type *type,
const char *description,
const char *callout_string);
Or by userspace invoking the request_key system call:
key_serial_t request_key(const char *type,
const char *description,
const char *callout_info,
key_serial_t dest_keyring);
The main difference between the two access points is that the in-kernel
interface does not need to link the key to a keyring to prevent it from being
immediately destroyed. The kernel interface returns a pointer directly to the
key, and it's up to the caller to destroy the key.
The userspace interface links the key to a keyring associated with the process
to prevent the key from going away, and returns the serial number of the key to
the caller.
===========
THE PROCESS
===========
A request proceeds in the following manner:
(1) Process A calls request_key() [the userspace syscall calls the kernel
interface].
(2) request_key() searches the process's subscribed keyrings to see if there's
a suitable key there. If there is, it returns the key. If there isn't, and
callout_info is not set, an error is returned. Otherwise the process
proceeds to the next step.
(3) request_key() sees that A doesn't have the desired key yet, so it creates
two things:
(a) An uninstantiated key U of requested type and description.
(b) An authorisation key V that refers to key U and notes that process A
is the context in which key U should be instantiated and secured, and
from which associated key requests may be satisfied.
(4) request_key() then forks and executes /sbin/request-key with a new session
keyring that contains a link to auth key V.
(5) /sbin/request-key execs an appropriate program to perform the actual
instantiation.
(6) The program may want to access another key from A's context (say a
Kerberos TGT key). It just requests the appropriate key, and the keyring
search notes that the session keyring has auth key V in its bottom level.
This will permit it to then search the keyrings of process A with the
UID, GID, groups and security info of process A as if it was process A,
and come up with key W.
(7) The program then does what it must to get the data with which to
instantiate key U, using key W as a reference (perhaps it contacts a
Kerberos server using the TGT) and then instantiates key U.
(8) Upon instantiating key U, auth key V is automatically revoked so that it
may not be used again.
(9) The program then exits 0 and request_key() deletes key V and returns key
U to the caller.
This also extends further. If key W (step 5 above) didn't exist, key W would be
created uninstantiated, another auth key (X) would be created [as per step 3]
and another copy of /sbin/request-key spawned [as per step 4]; but the context
specified by auth key X will still be process A, as it was in auth key V.
This is because process A's keyrings can't simply be attached to
/sbin/request-key at the appropriate places because (a) execve will discard two
of them, and (b) it requires the same UID/GID/Groups all the way through.
======================
NEGATIVE INSTANTIATION
======================
Rather than instantiating a key, it is possible for the possessor of an
authorisation key to negatively instantiate a key that's under construction.
This is a short duration placeholder that causes any attempt at re-requesting
the key whilst it exists to fail with error ENOKEY.
This is provided to prevent excessive repeated spawning of /sbin/request-key
processes for a key that will never be obtainable.
Should the /sbin/request-key process exit anything other than 0 or die on a
signal, the key under construction will be automatically negatively
instantiated for a short amount of time.
====================
THE SEARCH ALGORITHM
====================
A search of any particular keyring proceeds in the following fashion:
(1) When the key management code searches for a key (keyring_search_aux) it
firstly calls key_permission(SEARCH) on the keyring it's starting with,
if this denies permission, it doesn't search further.
(2) It considers all the non-keyring keys within that keyring and, if any key
matches the criteria specified, calls key_permission(SEARCH) on it to see
if the key is allowed to be found. If it is, that key is returned; if
not, the search continues, and the error code is retained if of higher
priority than the one currently set.
(3) It then considers all the keyring-type keys in the keyring it's currently
searching. It calls key_permission(SEARCH) on each keyring, and if this
grants permission, it recurses, executing steps (2) and (3) on that
keyring.
The process stops immediately a valid key is found with permission granted to
use it. Any error from a previous match attempt is discarded and the key is
returned.
When search_process_keyrings() is invoked, it performs the following searches
until one succeeds:
(1) If extant, the process's thread keyring is searched.
(2) If extant, the process's process keyring is searched.
(3) The process's session keyring is searched.
(4) If the process has a request_key() authorisation key in its session
keyring then:
(a) If extant, the calling process's thread keyring is searched.
(b) If extant, the calling process's process keyring is searched.
(c) The calling process's session keyring is searched.
The moment one succeeds, all pending errors are discarded and the found key is
returned.
Only if all these fail does the whole thing fail with the highest priority
error. Note that several errors may have come from LSM.
The error priority is:
EKEYREVOKED > EKEYEXPIRED > ENOKEY
EACCES/EPERM are only returned on a direct search of a specific keyring where
the basal keyring does not grant Search permission.
