From bbbe503ec1a5623a5a8abd003f46fdd8c3581054 Mon Sep 17 00:00:00 2001 From: "kay.sievers@vrfy.org" Date: Wed, 31 Mar 2004 23:12:57 -0800 Subject: [PATCH] netdev - udevdb+dev.d changes Here is a patch to change the netdev handling in the database and for the dev.d/ calls. I applies on top of the udevd.patch, cause klibc has no sysinfo(). o netdev's are also put into our database now. I want this for the udevruler gui to get a list of all handled devices. All devices in the db are stamped with the system uptime value at the creation time. 'udevinfo -d' prints it. o the DEVPATH value is the key for udevdb, but if we rename a netdev, the name is replaced in the kernel, so we add the changed name to the db to match with the remove event. NOTE: The dev.d/ scripts still get the original name from the hotplug call. Should we replace DEVPATH with the new name too? o We now only add a device to the db, if we have successfully created the main node or successfully renamed a netdev. This is the main part of the patch, cause I needed to clean the retval passing trough all the functions used for node creation. o DEVNODE sounds a bit ugly for netdev's so I exported DEVNAME too. Can we change the name? o I've added a UDEV_NO_DEVD to possibly skip the script execution and used it in udev-test.pl. udevstart is the same horror now, if you have scripts with logging statements in dev.d/ it takes minutes to finish, can we skip the scripts here too? o The get_device_type() function is changed to be more strict, cause 'udevinfo -a -p /block/' gets a class device for it and tries to print the major/minor values. o bugfix, the RESULT value has now a working newline removal and a test for this case. --- dev_d.c | 18 +++++++++++++----- 1 file changed, 13 insertions(+), 5 deletions(-) (limited to 'dev_d.c') diff --git a/dev_d.c b/dev_d.c index 9bb9507b9b..0910e4d323 100644 --- a/dev_d.c +++ b/dev_d.c @@ -64,11 +64,20 @@ static int run_program(char *name) void dev_d_send(struct udevice *dev, char *subsystem) { char dirname[256]; - char devnode[NAME_SIZE]; + char devname[NAME_SIZE]; - strfieldcpy(devnode, udev_root); - strfieldcat(devnode, dev->name); - setenv("DEVNODE", devnode, 1); + if (udev_dev_d == 0) + return; + + if (dev->type == 'b' || dev->type == 'c') { + strfieldcpy(devname, udev_root); + strfieldcat(devname, dev->name); + } else if (dev->type == 'n') { + strfieldcpy(devname, dev->name); + } + setenv("DEVNODE", devname, 1); /* FIXME: bad name for netif */ + setenv("DEVNAME", devname, 1); + dbg("DEVNAME='%s'", devname); strcpy(dirname, DEVD_DIR); strfieldcat(dirname, dev->name); @@ -81,4 +90,3 @@ void dev_d_send(struct udevice *dev, char *subsystem) strcpy(dirname, DEVD_DIR "default"); call_foreach_file(run_program, dirname, DEVD_SUFFIX); } - -- cgit v1.2.3-54-g00ecf
