[PATCH] patch for libsysfs sysfs directory handling
Here's a quick patch to:
1) Add an environment variable "SYSFS_PATH" that libsysfs will check
for when getting mount point before searching system's sysfs mount
point.
2) A quick fix to sysfs_get_link where the bug was.
I have tested this out with libsysfs and with udev. I couldn't test
with klibc because I haven't got the tree to build with klibc without
my changes either. I made the link but get an error finding
linux/linits.h. I will figure that out.
Please have a look at the patch. If it's agreeable, please test it. I
really want to add some generic path manipulation functions for the
sysfs_get_link error, rather than my patch's hack. But, I haven't had
time yet to do that. You really sounded like you needed this for
testing, so I'm sending it out to you. I should probably add a
function to set the env variable(?).
support subdirectory creation/removal for NAME="/devfs/is/crazy/video0"
create parent subdirs for device node if needed
remove subdirs when last node is removed
set uid/gid of node specified in udev.permissions
only numeric id's are supported cause we can't resolve with
klibc or libc before real /etc is mounted

[PATCH] udev init script
I integrated udev with Fedora Core. The main piece is simply building
/udev on boot, since we don't have an initramfs yet. We should also
clear out /udev on shutdown, for /udev directories mounted on persistent
media.
The attached script goes in /etc/init.d
Then do "chkconfig --add udev"
And the rest is handled automatically. I made it for Fedora but it will
probably work, with little change, on any Linux system.
Right now it only does sysfs-based discovery of block and tty devices,
since those are the only types of devices I have on my system. There is
a TODO in the script where we would add the other device types.
[PATCH] Fixup path for kernel includes when building with klibc.
Fixup path for kernel includes when building with klibc.
klibc expects the symlink klibc/linux to point to a relatively up
to date tree, use -Iklibc/linux/include to make linux/ and asm/
includes resolve properly, as these won't exist in the regular
klibc/klibc/include location.

[PATCH] man page update
here a new patch for the man page:
o namdev.permissions added
o corrected a few typos
o corrected text for config line format.
owner, group mode are only in namedev.permissions
(don't know what i was dreaming, while i wrote this :))
Here's the patch applying the latest libsysfs.
- adds the latest libsysfs code to udev
* new code includes dlist implementation, a generic linked list
implementation. Needed our own because LGPL
* rearranged structures
* provided more functions for accessing directory and attributes
- gets rid of ->directory->path references in namedev.c
- replaces sysfs_get_value_from_attributes with sysfs_get_classdev_attr

The problem is that the symlink is left dangling to an absolute location
in the build root, which won't exist on the installer's system. RPM 4.0
and on catches this.

[PATCH] udev: cool test scripts
This patch changes test.tty and test.block to add/remove each tty and
block device, respectively, on the system. Great way to
populate/unpopulate udev rapidly.
Its just a simple for loop over the sysfs entries.

[PATCH] udev spec file bits
Some spec file changes. Primarily, this makes the thing build without a
build root if so desired (i.e. build right out of /usr/src/redhat and
the standard file system). It should still build from a build root,
too.
Also:
- Add some Prereqs
- Pass RPM_OPT_FLAGS to make so we build with the RPM build
policy (i.e., optimizations, architecture, etc.)
- Specify the exact files in %files to make sure we install
everything properly and avoid a warning
This patch adds a callout config type to udev, so external programs can be
called to get serial numbers or id's that are not available as a sysfs
attribute.
1) removes the three database files for just one udevdb.tdb file.
2) adds udevdb_init() and udevdb_exit() functions
3) initializes database now in main() in udev.c.
The merge of tdb ended up breaking the ability to cross compile again, here's
a bk patch that yanks CC out of the tdb Makefile, and in turn falls back on
the exported CC value from the top-level Makefile which correctly sets it
based off of the CROSS value.
