[OE-core] [PATCH 3/4] syslinux: improve packaging

2011-05-02 Thread Otavio Salvador
Usually only parts of syslinux are used by products and thus syslinux
can be greatly reduced in size. This changes does it as:

 - syslinux: syslinux binary
 - syslinux-extlinux: extlinux binary
 - syslinux-mbr: mbr.bin
 - syslinux-chain: chain.c32
 - syslinux-pxelinux: pxelinux.0
 - syslinux-isolinux: isolinux.bin

[OE-core] RFC: Recipe based User Group addition, modification and deletion

2011-05-02 Thread Mark Hatle
RFC: Recipe based User  Group addition, modification and deletion

Problem:

In OE-Core we need a method for dynamically adding non-standard user and group
entries to the system.  This system must be flexible, extensible and easy to use
by the recipe authors.  We require this functionality in order to address
numerous system wide security requirements.  Among these requirements is the
necessity to enable non-root owned files (and eventually directories) in the
packages constructed by the build system.

Architecture:

The architecture design is based in part on the existing update-rc.d
infrastructure.  As such three choices for architecture were considered.  In
each of the descriptions below any references to the passwd file should also
assume a shadow file may exist, similarly any references to a group file should
assume a gshadow file may exist.

1) Enable a small set of native tools that can be used to manipulate the passwd
and group files in both pre and post install scripts as specified in the 
recipes.

The small set of tools should include: adduser, addgroup, moduser, modgroup,
deluser, delgroup, passwd and gpasswd.

This set of tools will enable the addition, modification and removal of specific
user and group entries, as well as enable the ability to set the corresponding
passwords for a given entry.  The tools in question also need to support shadow
password files.

In order to leverage the existing tooling it is expected that they will each be
modified to add a --root parameter that enables the program to either chroot
into a specific directory using the facilities provided by pseudo, or using the
item as an alternative mechanism to locate files on the disk.

A set of example pre and post install recipe instructions will be generated as
examples.

2) We add a new variable to the recipe syntax.  The variable will need to allow
a recipe to specify an arbitrary number of new users and groups, along with
their corresponding settings.

The update-rc.d.bbclass is used as an example for this item.  The new class
_useradd.bbclass_ will use a small number of variables to control user and group
creation.  As with update-rc.d, an 'inherit useradd' will be required in the
recipe to use this functionality.

The variable USERADD_PACKAGES will control which binary packages will have the
special user add code.  The corresponding USERADD_PARAM_pkg variable will
contain a list of parameters in the format of the command line useradd program
as document by useradd(8) man page.  Multiple parameters will be separated by a
semicolon (;).

For example, to add two new users for sendmail, you could use:

USERADD_PACKAGES = sendmail
USERADD_PARAM_sendmail = -u 47 -d /var/spool/mqueue -r -s /bin/true mailnull ;
-u 51 -d /var/spool/mqueue -r -s /bin/true smmsp

This would add two users, and their corresponding groups based on the rules of
the useradd program parameters.

For GROUP control, the vales would be changed to GROUPADD_PACKAGES and
GROUPADD_PARAM_pkg.  Note, many groups are automatically generated as part of a
useradd -- so specific group adds are only required in specific circumstances.

If both USERADD and GROUPADD are specified, the GROUPADD will always run before
the USERADD.  This ensures that new users can rely on similarly new groups.

Removal and modification of existing users is not supported by this approach.

The implementation of the actual add of user and group entries is up to the
packaging approach with a reasonable default approach specified.

3) Combine approaches 1 and 2.  Ensure that the recipe variable approach (2)
uses the mechanisms as implemented and defined in the command approach (1).

This will allow for the most flexibility, but also ensure that if a recipe needs
more then simple 'add' control it can be achieved.

---

It is recommended that the 3rd choice above be selected as the architecture for
the new functionality.  However, no matter which choice above is selected -- or
potentially even ones that are not listed above there are still some additional
items that will need to be resolved.

Any pre-installation steps will need to be preformed prior to the do_install()
stage of recipe building.  Otherwise the necessary user/group entries may not be
available which could lead to incorrect packaging occurring.  The passwd and
group files manipulated by this pre-install step will need to be global to the
sysroot, with PSEUDO specified to use this specific passwd and group file.
(PSEUDO_PASSWD environment variable specifies the path to a directory containing
a passwd and group file.)

The above will enable the ability to do, chown new_user:new_group path/file.
within a do_install() step.

During rootfs image creation, the pre-install steps will also need to be
executed prior to the package being installed -- or a suitable cleanup step run
that ensures the correct owners and groups for files (and directories) exist
after installation.  This will likely require changes to the various rootfs

 Hi

 I am trying to test this patch

 http://uclibc.org/~kraj/perf-tool-Fix-gcc-4.6.0-issues.patch

 to fix the build using gcc 4.6.0 but the kernel patching for yocto is
 not as usual as other recipes
 since it uses entire set of tooling around it.

 I tried to look around for documentation and few references I found

 https://wiki.pokylinux.org/wiki/Wind_River_Kernel

 discourages putting patches in metadata. and in another document it
 says it uses git to do patching but does not explain how.

 So if someone can explain in simple terms how to patch a linux-yocto
 would be really helpful from a
 developer POV or any documentation will be helpful.

 How do people develop/test patches on linux-yocto I understand
 eventually they are desired to be part
 of linux-yocto git but that comes after they are tried and tested locally

 I would have preferred to have the usual SRC_URI patching atleast for
 local testing. As of now
 it seems not to use normal OE recipe procedures.

 Are you actually not  seeing this work ? I put in place compatibility
 with existing patching via the SRC_URI for just this reason. A patch
 specified in the SRC_URI will be picked up by the tools and applied
 to the end of the BSP branch during the patching phase.


 if it worked. I would not be writing this email :)

 :) you never know, I didn't see your error message so I didn't want
 to presume.

 But I spoke too soon earlier, I had a bbappend in my layers that
 meant I was modifying the wrong SRC_URI to have your patch
 applied.

 When I modified the right SRC_URI like so:

 +SRC_URI = 
 git://git.yoctoproject.org/linux-yocto-2.6.37;protocol=git;nocheckout=1;branch=${KBRANCH},meta;name=machine,meta\
 +           file://perf-tool-Fix-gcc-4.6.0-issues.patch

 (i.e. the obvious way)

 I see the patch applied to the end of my BSP branch:

    GCC 4.6.0 in Fedora rawhide turned up some compile errors in tools/perf
    due to the -Werror=unused-but-set-variable flag.

    I've gone through and annotated some of the assignments that had side
    effects (ie: return value from a function) with the __used annotation,
    and in some cases, just removed unused code.

    In a few cases, we were assigning something useful, but not using it in

 I did modify the patch format slightly, since git am needs to be able to
 grok the patch for it to apply.

 Did you get any sort of error message when your patch didn't apply ?


yes it would not apply the patch and instead complained it could not
checkout a branch because tree was dirty
I dont have exact message handy. I will see if I can reproduce it

 Cheers,

 Bruce


 It has definitely worked during all the development cycles, so if you
 are seeing it not work, it's a bug and I'll fix it.

 Cheers,

 Bruce

 Hi Guys,

 Here is the design of network based PR service, please help to
 review and give you comment. Thanks a lot!

 Hi,

 looks good, just wondering if we can use the same mechanism for
 LOCALCOUNT numbers in SRCPV, we can even use same table if we
 prefix first column ie LOCALCOUNT_${PN} and CheckSum in 2nd column
 would be actuall git hash (from SRCREV or HEAD for AUTOREV) or 2nd
 table with similar structure.

 But it wont work very well if one builder is using AUTOREV and
 another one isn't, but that can be resolved by allowing only
 trusted builders with same configuration (wrt AUTOREV) to send such 
 tuples.

 Do we have at least 2 groups of users.
 1) trusted which increments PR when hash is not found
 2) public which can query PR for given hash (not sure what they should
    do if hash is not found)

 I think this points our something necessary.  There are manual
 indications of a change.  I.e. the current PR usage.  If I change
 the recipe, patches, etc I should expect to update the 'PR' to the
 next value.  However, if something ELSE changes (affecting the
 checksum), or an end user forgets to change the PR, the auto
 increment
 should be used.

 Why would you need to update the PR manually? Detecting changes in
 the recipe/patches/etc should all be handled by the checksumming.

 Checksums and timestamps are not enough to determine a logical
 progression of the components.

 We need something that informs the user where these changes fit in the
 grand scheme of things.  Are they newer or older then a recipe of the
 same name (and package version)?

 So this really allows us to visualize multiple levels of upstream work:

 Level 1 - Upstream version  (PV)

 Level 2 - Upstream (oe-core) recipe versioning (PR)

 ...

 Level N - Local build and configuration versioning (checksum based 
 auto incrementing)


 In a lot of projects 1, 2 and N are enough.. but it's understandable
 to add in other intermediate levels to indicate different upstreams along 
 the way.
 (Such as if a company has their own internal distribution..)

 I've seen cases where a level 3 exists to indicate a distribution version..

 Level N (when done manually) has usually captured major system
 configuration changes and rebuilding in order to enable solver tools to 
 upgrade properly.


 While the checksum will be able to point a unique instance of the
 recipe to a given PR... it doesn't guaranty any type of logical
 numbering.. other then a new checksum is a new (presumably larger) PR
 number.  By adding in the various levels of version information the
 checksum becomes more unique as it only refers to specific
 'upstream' revisions, and make it more logical that a level 1, 2, ... N 
 change means it's a newer version of the package.


 If a new PV(and/or PR) value comes, does the level N value need to be reset 
 to 0? Or should it continue to increase?


I am in favor of reseting it to 0

 Best Regards,
 Lianhao

I can't figure out one case that nfs root works and ext3 image doesn't...

Hi

I am seeing qemu segfaulting when booting ext3 image. The same rootfs
boots fine over nfs. It does not give any useful message
as to what happened. I am using the runqemu script. Same used to work
fine 3 weeks back. I tried to blame compilers but the behavior
is same irrespective of gcc version I use or even eglibc/uclibc

Its on x86_64/ubuntu 11.04 host.

Anyone experiencing it ? bisecting can be a long excercise for this.

Thanks
