From 8a0acf85f25d2fb4659aafbad7db2fe48a58307d Mon Sep 17 00:00:00 2001 From: "kay.sievers@vrfy.org" Date: Mon, 22 Mar 2004 22:18:34 -0800 Subject: [PATCH] [PATCH] make udevtest a real program :) Here are the missing pieces for udevtest. A simple man page is added, the blacklist is removed, cause it can't work without having a subsystem. The Makefile removes all manpages now with a uninstall and installs udevtest in /usr/bin/. Any old version from /sbin/ should be deleted by hand. The only expected argument is the sysfs devpath, here I changed it to be more tolerant to the input. The path may now be specified with or without a leading slash and optionally with the /sys moutpoint prepended. I hope this will end the confusion about the use of this program :) --- Makefile | 7 ++++- udevtest.8 | 17 +++++++++++ udevtest.c | 83 ++++++++++++++++++++++-------------------------------- 3 files changed, 56 insertions(+), 51 deletions(-) create mode 100644 udevtest.8 diff --git a/Makefile b/Makefile index 612911c44..000918573 100644 --- a/Makefile +++ b/Makefile @@ -382,10 +382,11 @@ install: install-initscript install-config install-dbus-policy all $(INSTALL_PROGRAM) -D $(DAEMON) $(DESTDIR)$(sbindir)/$(DAEMON) $(INSTALL_PROGRAM) -D $(SENDER) $(DESTDIR)$(sbindir)/$(SENDER) $(INSTALL_PROGRAM) -D $(INFO) $(DESTDIR)$(usrbindir)/$(INFO) - $(INSTALL_PROGRAM) -D $(TESTER) $(DESTDIR)$(sbindir)/$(TESTER) + $(INSTALL_PROGRAM) -D $(TESTER) $(DESTDIR)$(usrbindir)/$(TESTER) $(INSTALL_PROGRAM) -D $(STARTER) $(DESTDIR)$(sbindir)/$(STARTER) $(INSTALL_DATA) -D udev.8 $(DESTDIR)$(mandir)/man8/udev.8 $(INSTALL_DATA) -D udevinfo.8 $(DESTDIR)$(mandir)/man8/udevinfo.8 + $(INSTALL_DATA) -D udevtest.8 $(DESTDIR)$(mandir)/man8/udevtest.8 $(INSTALL_DATA) -D udevstart.8 $(DESTDIR)$(mandir)/man8/udevstart.8 $(INSTALL_DATA) -D udevd.8 $(DESTDIR)$(mandir)/man8/udevd.8 - ln -f -s udevd.8 $(DESTDIR)$(mandir)/man8/udevsend.8 @@ -408,6 +409,10 @@ uninstall: uninstall-dbus-policy - rm $(initdir)/udev - rm $(mandir)/man8/udev.8 - rm $(mandir)/man8/udevinfo.8 + - rm $(mandir)/man8/udevtest.8 + - rm $(mandir)/man8/udevstart.8 + - rm $(mandir)/man8/udevd.8 + - rm $(mandir)/man8/udevsend.8 - rm $(sbindir)/$(ROOT) - rm $(sbindir)/$(DAEMON) - rm $(sbindir)/$(SENDER) diff --git a/udevtest.8 b/udevtest.8 new file mode 100644 index 000000000..f23e21924 --- /dev/null +++ b/udevtest.8 @@ -0,0 +1,17 @@ +.TH UDEVTEST 8 "March 2004" "" "Linux Administrator's Manual" +.SH NAME +udevtest \- simulates a udev run to test the configured rules +.SH SYNOPSIS +.BI udevtest " sysfs_device_path" +.SH "DESCRIPTION" +.B udevtest +simulates a +.B udev +run for the given device, and prints out the node names +for the given device, the real udev would have created. +.SH "SEE ALSO" +.BR udev (8) +.SH AUTHORS +.B udevtest +was developed by Greg Kroah-Hartman with much help +from others. diff --git a/udevtest.c b/udevtest.c index e67d45257..95b85dd8b 100644 --- a/udevtest.c +++ b/udevtest.c @@ -37,6 +37,7 @@ char **main_argv; char **main_envp; + #ifdef LOG unsigned char logname[LOGNAME_SIZE]; void log_message (int level, const char *format, ...) @@ -51,72 +52,54 @@ void log_message (int level, const char *format, ...) } #endif -static char *subsystem_blacklist[] = { - "net", - "scsi_host", - "scsi_device", - "usb_host", - "pci_bus", - "pcmcia_socket", - "" -}; - -static int udev_hotplug(void) +int main(int argc, char *argv[], char *envp[]) { char *devpath; - char *subsystem; - int retval = -EINVAL; - int i; + char temp[NAME_SIZE]; + char subsystem[] = ""; + const int fake = 1; + + main_argv = argv; + main_envp = envp; + + info("version %s", UDEV_VERSION); - devpath = main_argv[1]; - if (!devpath) { - dbg("no devpath?"); + if (argv[1] == NULL) { + info("udevinfo expects the DEVPATH of the sysfs device as a argument"); goto exit; } - dbg("looking at '%s'", devpath); + + /* initialize our configuration */ + udev_init_config(); + + /* remove sysfs_path if given */ + if (strncmp(argv[1], sysfs_path, strlen(sysfs_path)) == 0) + devpath = argv[1] + strlen(sysfs_path); + else + if (argv[1][0] != '/') { + /* prepend '/' if missing */ + strfieldcpy(temp, "/"); + strfieldcat(temp, argv[1]); + devpath = temp; + } else { + devpath = argv[1]; + } + + info("looking at '%s'", devpath); /* we only care about class devices and block stuff */ if (!strstr(devpath, "class") && !strstr(devpath, "block")) { - dbg("not a block or class device"); + info("not a block or class device"); goto exit; } - /* skip blacklisted subsystems */ - subsystem = main_argv[1]; - i = 0; - while (subsystem_blacklist[i][0] != '\0') { - if (strcmp(subsystem, subsystem_blacklist[i]) == 0) { - dbg("don't care about '%s' devices", subsystem); - goto exit; - } - i++; - } - - /* initialize our configuration */ - udev_init_config(); - /* initialize the naming deamon */ namedev_init(); /* simulate node creation with fake flag */ - retval = udev_add_device(devpath, subsystem, 1); + udev_add_device(devpath, subsystem, fake); exit: - if (retval > 0) - retval = 0; - - return -retval; -} - -int main(int argc, char *argv[], char *envp[]) -{ - main_argv = argv; - main_envp = envp; - - dbg("version %s", UDEV_VERSION); - - return udev_hotplug(); + return 0; } - - -- 2.30.2
