[PATCH] replace fgets() with mmap() and introduce udev_lib.[hc] Here we replace the various fgets() with a mmap() call for the config file reading, due to the reported performance problems with klibc. Thanks to Patrick's testing, it makes a very small, close to nothing speed gain for libc users, but a 6 times speed increase for klibc users with a 1000 line config file. I've created a udev_lib.[hc] for this and also moved all the generic stuff from udev.h in there and uninlined the functions.

[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] udev - safer string handling - part three Here we truncate our input strings from the environment to our defined limit. It's a bit theroretical but better check for it. It cleans up some magic length definitions and removes the code duplication in udev, udevtest and udevsend. udevd needs to be killed after installation, cause the message size is changed with this patch. Should we do this with the 'make install', like we do with the '.udevdb'?

The device list is sorted in alphabetical order now and if there are only a few recently discovered devices, they are placed on top of the list. For those who want to have a look: http://vrfy.org/projects/udev/udevruler.png The patch applies on top of today's mmap() patch. The db format is changed to have the file and line number of the applied rule. So it should be easy to edit the matching rule with this beast. It compiles with "make all udevruler".

[PATCH] big cleanup of internal udev api Here is the first patch to cleanup the internal processing of the various stages of an udev event. It should not change any behavior, but if your system depends on udev, please always test it before reboot :) We pass only one generic structure around between add, remove, namedev, db and dev_d handling and make all relevant data available to all internal stages. All udev structures are renamed to "udev". We replace the fake parameter by a flag in the udev structure. We open the class device in the main binaries and not in udev_add, to make it possible to use libsysfs for udevstart directory crawling. The last sleep parameters are removed.

[PATCH] Make udev/udevstart be one binary Hi, The following patch makes udev/udevstart be a common binary. First, doing this grows udev by a total of 1.8kB (ppc32, stripped) whereas udevstart by itself is 6.4kB. I know you mentioned being able to replace udevstart with a script, but at 1.8kB I don't think it'll be easy to beat this with size there. Next, the following are by-eye timings of before, after, and with devfs on a slow, but still usable embedded platform (config stripped down to more-or-less bare for ramdisk): -- Embedded Planet RPX LITE, 64Mhz MPC 823e -- devfs : 15.333s, 15.253s, 14.988s (15.191s avg) udev-pristine : 18.675s, 18.079s, 18.418s (18.390s avg) udev-multi : 14.587s, 14.747s, 14.868s (14.734s avg) The patch ends up being rather large to add this, as in doing so I ended up making all refs (that I hit..) to devpath/subsystem be marked as 'const'.
