2014-04-24udev: remove seqnum API and all assumptions about seqnumsKay Sievers
The way the kernel namespaces have been implemented breaks assumptions udev made regarding uevent sequence numbers. Creating devices in a namespace "steals" uevents and its sequence numbers from the host. It confuses the "udevadmin settle" logic, which might block until util a timeout is reached, even when no uevent is pending. Remove any assumptions about sequence numbers and deprecate libudev's API exposing these numbers; none of that can reliably be used anymore when namespaces are involved. Signed-off-by: Anthony G. Basile <blueness@gentoo.org>

2014-04-05Revisit issue #87: fails to build on linux headers 3.13Anthony G. Basile
We switch to defining _GNU_SOURCE as we do for cdrom_id.c for a more consistant approach to this issue. Signed-off-by: Anthony G. Basile <blueness@gentoo.org>
2014-04-04libudev: Fix redefinition of usec_t and nsec_t.Eric Le Bihan
The type definitions usec_t and nsec_t where defined twice: in path-util.h and util.h. time-util.h and time-util.c now gather the time-related functions and definitions (as in upstream systemd).

2014-03-28udev: persistent naming - we cannot use virtio numbers as they are not stableTom Gundersen
This reverts commit 8741f2defaf26aafe5ee0fd29954cfdf84ee519c: 'Add virtio-blk support to path_id' and commit e3d563346c4237af23335cc6904e0662efdf62ad: 'udev: net_id - handle virtio buses'. Distros may want to take note of this, as it changes behavior. Signed-off-by: Anthony G. Basile <blueness@gentoo.org>

2014-03-22Revisit issue #87: fails to build on linux headers 3.13Anthony G. Basile
Dropping <fcntl.h> in favor of <linux/fcntl.h> is incorrect. Yet uClibc needs O_CLOEXEC from <linux/fcntl.h>. So we re-introduce <fcntl.h> and include <linux/fcntl.h> only on uClibc systems to avoid redefinitions. Signed-off-by: Anthony G. Basile <blueness@gentoo.org>

2014-03-17input_id: Recognize buttonless joystick typesMartin Pitt
Input devices like rudders or pedals are joystick-like; they don't have buttons, but axes like RX, THROTTLE, or RUDDER. These don't interfere with other device types with absolute axes (touch screens, touchpads, and accelerometers), so it's fairly safe to mark them as ID_INPUT_JOYSTICK and thus hand out dynamic ACLs to the user. https://bugs.freedesktop.org/show_bug.cgi?id=70734
2014-03-17udev: properly detect reference to unexisting part of PROGRAM's resultLukas Nykryn
2014-03-17Use strlen even for constant stringsJosh Triplett
GCC optimizes strlen("string constant") to a constant, even with -O0. Thus, replace patterns like sizeof("string constant")-1 with strlen("string constant") where possible, for clarity. In particular, for expressions intended to add up the lengths of components going into a string, this often makes it clearer that the expression counts the trailing '\0' exactly once, by putting the +1 for the '\0' at the end of the expression, rather than hidden in a sizeof in the middle of the expression.

2014-03-15Fix issue #87: fails to build on linux headers 3.13Anthony G. Basile
Commit 80b10107cb added #include <linux/fcntl.h> in src/accelerometer and friends for builds on uclibc. This only works with glibc and musl systems with linux headers 3.9 but fails with linux headers 3.13. We keep <linux/fcntl.h> but drop <fcntl.h>. Signed-off-by: Anthony G.

2014-02-28cdrom_id: use the old MMC fallbackLukas Nykryn
https://bugzilla.redhat.com/show_bug.cgi?id=1038015 The problem seems to be that the your virtual DVD is emulating a really old DVD device, and doing it kind of strangely. > dracut:# /lib/udev/cdrom_id --debug /dev/sr0 > probing: '/dev/sr0' > INQUIRY: [IMM ][Virtual CD/DVD ][0316] > GET CONFIGURATION failed with SK=5h/ASC=24h/ACQ=00h So your virtual drive rejects the GET CONFIGURATION command as illegal. Other pre-MMC2 drives that don't accept this command usually return the error SK=5h,ASC=20h (invalid/unsupported command code), in which case cdrom_id tries an older method, and then ID_CDROM_MEDIA_TRACK_COUNT_DATA gets set and all the /dev/disk/by-label (etc) links get set up. The virtual drive returns the error SK=5h,ASC=24h (invalid field in Command Descriptor Block), which cdrom_id doesn't handle, so it gives up and the links never get made. The ideal solution would be to make the IMM to emulate a device that's less than 15 years old, but I'm not going to hold my breath waiting for that. So probably cdrom_id should also use the old MMC fallback when the error is SK=5h,ASC=24h, and then all of this would work as expected.

2014-02-02use memzero(foo, length); for all memset(foo, 0, length); callsGreg KH
In trying to track down a stupid linker bug, I noticed a bunch of memset() calls that should be using memzero() to make it more "obvious" that the options are correct (i.e. 0 is not the length, but the data to set). So fix up all current calls to memset(foo, 0, length) to memzero(foo, length). Signed-off-by: Anthony G. Basile <blueness@gentoo.org>

2014-01-20udev/udevadm-hwdb.c: remove usage of qsort_rrofl0r
while theoretically a nice interface, qsort_r on GLIBC was implemented with a prototype that shuffles the argument order around when compared to the traditional BSD implementations, yielding in 2 separate incompatible implementations. even worse, the arguments are all of pointer type so one would not even notice that the order is wrong and so this would yield in crashes or silent memory corruption. thus musl does not implement it, because configure scripts would check for its existance and use it unconditionally, even when assuming the BSD version. a more portable solution is to use TLS via __thread, which any modern GCC should provide. (even 3.4.6 on x86/x86_64 does so). Signed-off-by: Anthony G. Basile <blueness@gentoo.org>
