[PATCH] major database cleanups Now we standardise on a struct udevice to pass around, and store in the database. This cleaned up the database code a lot.
2003-10-20 22:48:44 -07:00
#include "libsysfs/libsysfs.h"
[PATCH] udev - keep private data out of the database? Shouldn't we keep the temporary strings out of the database, or is this information useful for something? It cuts the length of the data from 628 to 275 bytes.
2004-02-12 22:51:44 -08:00

[PATCH] Build failure - missing linux/limits.h include? On Tuesday 25 November 2003 00:12, Chris Larson wrote: > udev fails to compile here unless I'm doing a KLIBC build.

I'd think it'd be best to add a #include <linux/limits.h> to > udev.h directly, since it uses PATH_MAX. No, don't include kernel headers directly if you can avoid it. The problem you are referring to seems to be with old tool chains, I have the same symptom with my s390 gcc-2.95/glibc-2.1.3. Including <sys/param.h> instead of <limits.h> seems to fix it.

[PATCH] add support for a main udev config file, udev.conf. the older udev.config file is now called udev.rules. This allows us to better control configuration values, and move away from the environment variables.

[PATCH] put config files and database in /etc/udev by default Can be overridden on the makefile line.

[PATCH] add initial libsysfs support... needs lots more cleanup, but is much nicer than doing this by hand...

#define OWNER_SIZE 30

[PATCH] set default owner/group in db - update I've edited the man page today, so this is alreay included :) Also a few more trivials: o added the defaults to udev.conf.in o removed class_dev from get_default_mode(), to match with Hanna's o changed size of mode_str to MODE_SIZE o changed a few char compares from from 0x00 to '\0'

[PATCH] more robust config file parsing in namedev.c After getting a number of different crashes for udev reading broken udev.config files, I decided to try to make the parser a little more robust. The behaviour is changed to stop reading the configuration file and logging the broken entry instead of silently ignoring it (is that good? It's easy to just print and continue). All strcpy()'s to a fixed length string are now implicitly limited to the bounds of the target string. I kept the -ENODEV return code for now, not sure if there should be different ones.

[PATCH] add udevtest program to build Also fix up some other dependancy issues in the Makefile. Thanks to Olaf Hering <olh@suse.de> for pointing them out.

[PATCH] enabled debugging.
2003-04-10 20:04:38 -07:00
[PATCH] add callout config type to udev 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.

[PATCH] set default owner/group in db. This patch fixes a bug where the udev database stored empty strings for Owner and Group if they were default. This patch stores the default value into the database if not set otherwise. See example output: crw------- 1 root root 4, 65 Jan 16 11:13 ttyS1 P: /class/tty/ttyS1 N: ttyS1 S: O: root G: root This is a bit of a hack. However, until udev supports setting the o/g values they will be root/root anyway so the database might as well reflect the truth instead of empty strings.

[PATCH] fix log option code so that it actually works for all udev programs. Also introduce boolean type for config file to use.
