2014-04-26udev: warn when name_to_handle_at is not implementedZbigniew Jędrzejewski-Szmek
We have a bunch of reports from people who have a custom kernel and are confused why udev is not running. Issue a warning on error. Barring an error in the code, the only error that is possible is ENOSYS. https://bugzilla.redhat.com/show_bug.cgi?id=1072966
2014-04-26util: make sure all our name_to_handle_at() code makes use of file_handle_unionLennart Poettering

2014-04-26implement a union to pad out file_handleDave Reisner
Cases where name_to_handle_at is used allocated the full struct to be MAX_HANDLE_SZ, and assigned this size to handle_bytes. This is wrong since handle_bytes should describe the length of the flexible array member and not the whole struct. Define a union type which includes sufficient padding to allow assignment of MAX_HANDLE_SZ to be correct. Signed-off-by: Anthony G. Basile <blueness@gentoo.org>

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>
2014-04-04libudev: 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).

2014-02-02use 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>
2014-01-25src/libudev/util.h: import FORMAT_TIMESPAN_MAX for selinuxAnthony G. Basile
When configure --enable-selinux, we hit a compile time error with a missing definition of FORMAT_TIMESPAN_MAX. This was imported from upstream's src/shared/time-util.h into our src/libudev/util.h.

2014-01-09Add more _printf_'s for format-nonliteralsThomas Hindoe Paaboel Andersen
Clang is a bit more strict wrt format-nonliterals: http://clang.llvm.org/docs/LanguageExtensions.html#format-string-checking Adding these extra printf attributes also makes gcc able to find more problems. E.g. this patch uncovers a format issue in udev-builtin-path_id.c Some parts looked intetional about breaking the format-nonliteral check. I added some supression for warnings there.

2014-01-09libudev: always return NULL in _unref() APIsLennart Poettering
Returning anything else but NULL would suggest the caller's reference might still be valid, but it isn't, because the caller just invoked _unref() after all. This turns the return value into a typesafe shortcut that allows unreffing and resetting a reference in one line. In contrast to solutions for this which take a pointer to a pointer to accomplish the same this solution is just syntactic sugar the developer can make use of but doesn't have to, and this is particularly useful when immediately unreffing objects returned by function calls.

2014-01-09device-nodes: move device node specific code to own fileDave Reisner
In the process, rename udev_encode_string which is poorly named for what it does. It deals specifically with encoding names that udev creates and has its own rules: utf8 is valid but some ascii is not (e.g. path separators), and everything else is simply escaped. Rename it to encode_devnode_name. Adopted for eudev: Anthony G. Basile <blueness@gentoo.org> Signed-off-by: Anthony G. Basile <blueness@gentoo.org>
2014-01-09move utf8 functions from libudev-private.h to utf8.hDave Reisner
There's now some more obvious overlap amongst the two utf8 validation functions, but no more than there already was previously.

2013-09-10libudev: enumerate - do not try to match against an empty subsystemKay Sievers
2013-09-10libudev: enumerate: fix NULL-deref for subsystem-matchesDavid Herrmann
udev_device_get_subsystem() may return NULL if no subsystem could be figured out by libudev. This might be due to OOM or if the device disconnected between the udev_device_new() call and udev_device_get_subsystem(). Therefore, we need to handle subsystem==NULL safely. Instead of testing for it in each helper, we treat subsystem==NULL as empty subsystem in match_subsystem().

2013-09-10libudev: fix memleak when enumerating childsDavid Herrmann
We need to free udev-devices again if they don't match. Funny that no-one noticed it yet since valgrind is quite verbose about it. Fix it and free non-matching devices.
2013-09-10libudev-enumerate.c:udev_enumerate_get_list_entry() fixed possible stale pointerHarald Hoyer
If a realloc() happens in syspath_add(), the move_later pointer could point to an invalid memory region. Let move_later store the array index, instead of the pointer to the entry.
