2013-04-03lib: use O_CLOEXEC in libcommonKarel Zak1-2/+2
Signed-off-by: Karel Zak <kzak@redhat.com>
2013-01-08include: cleanup copyright headersKarel Zak1-1/+5
We use the code from include/ and lib/ on many places, so use public domain if possible or LGPL for code copied from libs. Signed-off-by: Karel Zak <kzak@redhat.com>

2012-05-10libuuid: avoid double open and leaking fd (reworked)Petr Uzel1-5/+3
This reverts commit 6126f7a53c57485a9a29ddd772765695f23c92e6 and fixes the double open and leaking descriptor in a different way, that is by using newly introduced function 'have_random_source()' to check whether good random source is available while deciding which uuid type to generate (random/time). This is better than calling random_get_fd() twice, passing the file descriptor down the stack and reusing it in next call to random_get_fd(). Signed-off-by: Petr Uzel <petr.uzel@suse.cz>
2012-05-04libuuid: avoid double open and leaking descriptorPetr Uzel1-3/+5
We are opening /dev/urandom twice in uuid_generate(): first to check if the file is available and then later __uuid_generate_random() again to actually get the random data. Moreover, descriptor from the first open is leaking. Fix by passign the descriptor down the stack and reusing it there.

2012-04-10lib: random utilitiesDavidlohr Bueso1-0/+120
Add a random number(s) generator specific file. The intial functions are based on what libuuid provide. I did some modifications like avoid WIN32 checks - this is util-LINUX. [kzak@redhat.com: - move jrand_seed to lib/randutils.c - use TLS for jrand_seed (like original code from libuuid) - use size_t for buffer sizes - add close() to random_get_bytes] Signed-off-by: Davidlohr Bueso <dave@gnu.org> Signed-off-by: Karel Zak <kzak@redhat.com>
