Introduce a library routine to package the idiom: p = xmalloc(b, n); memcpy(p, b, n); and use it where possible.

2013-05-13mdev: use $DEVNAME in uevent sysfs file for device node nameNikolaus Voss
516530c932bd17d87c9eb4347a490be051e495f4 uses $DEVNAME variable for device node name. This is fine, but only works for hotplugging, "mdev -s" will behave differently when DEVNAME and basename(path) differ. This patch extracts the DEVNAME from the uevent sysfs file in make_device(), thus works for hot- and coldplugging; so using the environment DEVNAME on hotplug events is no longer necessary.

2013-02-27mdev: improve $SEQ handling; improve debug loggingDenys Vlasenko
Sequential run of concurrent mdev's was too simplistic: they waited for /dev/mdev.seq to match. This could sometimes cause cumulative loss of time on the order of a second. Added SIGCHLD signaling from exiting mdev to all other mdev's. Added debugging required to see that code actually works as intended. Example of /dev/mdev.log (with "woken up" elevated from dbg lvl 3 to 2): mdev[1023]: first seq written ^^^^ seq, not pid mdev[1023]: 35.022395 ACTION:add SUBSYSTEM:module DEVNAME:(null) DEVPATH:/module/lib80211 mdev[1023]: rule matched, line -1 ^^^^^^^ means "default rule" mdev[1023]: 35.022676 exiting ^^^^^^^^^ second,usec timestamp mdev[1024]: 35.069691 ACTION:add SUBSYSTEM:vc DEVNAME:vcs9 DEVPATH:/devices/virtual/vc/vcs9 mdev[1024]: dev 7,9 mdev[1025]: 35.069889 waiting for '1024' mdev[1026]: 35.069946 waiting for '1024' mdev[1027]: 35.070151 waiting for '1024' mdev[1024]: rule matched, line -1 mdev[1024]: mknod vcs9 (7,9) 20660 0:0 mdev[1024]: 35.070346 exiting mdev[1025]: woken up mdev[1026]: woken up mdev[1025]: 35.071213 ACTION:add SUBSYSTEM:vc DEVNAME:vcsa9 DEVPATH:/devices/virtual/vc/vcsa9 ^^^^^^^^^ took only a millisecond to start running after prev mdev exited mdev[1025]: dev 7,137 mdev[1027]: woken up mdev[1025]: rule matched, line -1 mdev[1025]: mknod vcsa9 (7,137) 20660 0:0 mdev[1025]: 35.072109 exiting function old new delta mdev_main 849 1372 +523 curtime - 59 +59 dirAction 87 134 +47 static.ts - 8 +8 keywords 19 12 -7 make_device 2189 2119 -70 Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
