2005-04-26[PATCH] add RUN key to be able to run rule based notificationkay.sievers@vrfy.org
SUBSYSTEM=="block", RUN="/sbin/program" will execute the program only for block device events. ACTION="remove", SUBSYSTEM=="block", RUN"/sbin/program" will execute the program, if a block device is removed.

2005-04-26[PATCH] disable logging for udevstartkay.sievers@vrfy.org
The slow logging facilites on some systems are a reason for the reported slowness of udevstart. On one of my boxes udevstart is down from 9 second to 0.3 seconds.
2005-04-26[PATCH] Make dev.d/ handling a separate processing stagekay.sievers@vrfy.org
Move the logic when and how to call the dev.d/ scripts into the main processing path.
2005-04-26[PATCH] make the udev object available to more processing stageskay.sievers@vrfy.org
Remove the overwriting of main_argv[] hack and use the values from the udev object. Pass the udev object to call_foreach_file(). In the udevstart case, export SUBSYSTEM and UDEVSTART to the environment.
2005-04-26[PATCH] add ACTION to udev object to expose it to the whole processkay.sievers@vrfy.org
2005-04-26[PATCH] cleanup netif handling and netif-dev.d/ eventskay.sievers@vrfy.org
Here we supress the dev.d/ execution if we didn't change a network interface's name with a rule. This should solve the issue of two running dhclients for the same interface, cause the /etc/dev.d/net/hotplug.dev script that fakes the hotplug event runs with every udevstart for every interface and fakes a second identical hotplug event on bootup. With this patch netif interfaces are no longer stored in the udevdb. It is not needed, cause we don't have permissions or symlinks :) and all information is available in sysfs. This patch also moves the dev_d execution calls out of the udev_add/udev_remove. As with the former api-cleanup-patch we have all processed data in one udev struct and can place the execution calls where needed.
2005-04-26[PATCH] big cleanup of internal udev apikay.sievers@vrfy.org
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.
2005-04-26[PATCH] fix problems using scsi_id with udevstartkay.sievers@vrfy.org
when udevstart was running we didn't set the environment and the subsystem argument for the callouts the dev.d/ scripts. Here is a fix, that sets that with every udevstart iteration, corrects argv[0] to be the basename() only not the whole path and adds a test for invoking callouts without arguments.

We may just test if we are there > instead of the "device" match. How about something like this. It adds all the net devices without looking at the attributes and keeps the remaining logic like it is. It also removes certain levels of indirection and much simplifies the udevstart process. We surely don't need to open and close the udevdb for every node while iterating over the list. (We are about 5% faster on my box) It's not well tested, so it would be nice if someone can have a look at it, before a broken udevstart renders any system unbootable.
2005-04-26[PATCH] fix UDEV_NO_SLEEPtrini@kernel.crashing.org
Move setting UDEV_NO_SLEEP into main(). I thought about moving udev_init_config() around, but it still must be invoked in both udev and udevstart cases, and before udev_hotplug() is called. An alternative would be to have main() do: if (is_udevstart) { ... current ... } else { udev_init_config(); return udev_hotplug(); } And move setting UDEV_NO_SLEEP into udev_start(). I can redo it that way, if you prefer. Signed-off-by: Tom Rini <trini@kernel.crashing.org> Signed-off-by: Greg Kroah-Hartman <greg@kroah.com>
2005-04-26[PATCH] Make udev/udevstart be one binarytrini@kernel.crashing.org
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'.

Sorry, udevstart needs a small cleanup after my recent copy/pastes.
2005-04-26[PATCH] DEVPATH for netdevkay.sievers@vrfy.org
Here we change the DEVPATH for netdev's in the environment of the dev.d/ scripts to the name the device is renamed to. The original name doesn't exist in the kernel after rename.
2005-04-26[PATCH] udevd race conditions and performance, assorted cleanupschris_friesen@sympatico.ca
This patch covers a number of areas: 1) sysfs.h is fixed up to use the common dbg() macro. This fixes the case where DEBUG is defined but USE_LOG isn't. 2) udevstart.c is modified to include the proper headers, rather than getting them indirectly which can break depending on Makefile flags 3) udevd.c gets some major changes: a) I added a pipe from the signal handler. This fixes the race conditions that I mentioned earlier. Basically, the point of the pipe is to force the select() call to return immediately if a signal handler fired before we actually started the select() call. This then lets us run the appropriate code based on flags set in the signal handler proper. b) I added a number of flags to coalesce calls to common routines. This should make things slightly more efficient. c) since most calls will tend to come in with a sequence number larger than what has been received, I switched msg_queue_insert() to scan the msg_list backwards to improve performance. filename="udevd.diff"
2005-04-26[PATCH] udevstart fixesmd@Linux.IT
udevstart_no_retval: currently udevstart will always return rc=22 because of the error handling code. I completely removed it because it is not used, and returning a generic error to the init script is not much useful anyway.
2005-04-26[PATCH] overall trivial trivial cleanupkay.sievers@vrfy.org
Here I try to make the style a bit more consistant in the different files, so that new patches just copy the 'right' one :) Some "magic" numbers are replaced and udevtest.c is catched up with udev.
2005-04-26[PATCH] cleanup udevstartkay.sievers@vrfy.org
I just wanted to terminate the snprintf() strings, cause I can see a overflow with closed eyes after all the audit :) But then I changed a bit more to bring it in line with the style of the other files. I replaced the exec_udev() function with the one from udevd, cause we don't need to read the stdout from udev. Please have a look if it still works for you too and not only for usernames with 3 characters :)
2005-04-26[PATCH] add udevstart program based on a old patch from Harald Hoyer ↵greg@kroah.com
