* libuuid: fix name-based UUIDsKarel Zak2018-08-311-18/+16Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current version is not fully compatible with RFC4122. It incorrectly encodes UUID variant xxxxxxxx-xxxx-Mxxx-Nxxx-xxxxxxxxxxxx where M is UUID version and N is UUID variant. $ python -c "import uuid ; print(uuid.uuid5(uuid.UUID(int=0), 'foo'))" aa752cea-8222-5bc8-acd9-555b090c0ccb ^^ Old version: $ uuidgen --namespace 00000000-0000-0000-0000-000000000000 --name 'foo' --sha1 aa752cea-8222-5bc8-8cd9-555b090c0ccb ^^ Fixed version: ./uuidgen --namespace 00000000-0000-0000-0000-000000000000 --name 'foo' --sha1; aa752cea-8222-5bc8-acd9-555b090c0ccb ^^ The patch uses uuid_unpack and uuid_pack. It makes code more readable and allow to access proper octens. The same way we already use for time and random based UUIDs.

* build-sys: remove generated headers from dist tar ballRuediger Meier2018-01-221-3/+1Star
| | | | | | | | | | | | | Headers should only be listed in either *_HEADERS or *_SOURCES, especially when we want nodist_*_HEADERS. Since all the generated headers are made by configure we don't even need to use BUILT_SOURCES or other tricks.

* libuuid: use access(2) when checking /dev/random availabilitySami Kerola2017-08-051-3/+2Star

* build: use --runstatedir instead of --localstatedirAndreas Henriksson2017-07-311-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The util-linux code was previously aligned to use @localstatedir@ and the util-linux build system was set to override the default to use /run. Current GNU Coding Standards introduced the @runstatedir@ variable for this purpose. Lets use that instead. The GNU default for @runstatedir@ is ${localstatedir}/run so util-linux still override the default to be /run to preserve the status quo from before. The only difference is that you'll now pass --runstatedir to override the location on the command line instead of --localstatedir. (FWIW, Debhelper in compat 11 will automatically start passing --runstatedir=/run to all autotools configured builds. It already passes --localstatedir=/var (to avoid it ending up with the GNU default /usr/local/var) which breaks the util-linux build system code that tries to default it to /run. This change will thus allow util-linux and debhelper to work better together and avoid the need for a package-specific override.)

* Only move shared libraries to /lib if they existsThomas Petazzoni2014-06-161-1/+1
| | | | | | | | | | | | | | | | | | In several Makemodule.am, there is a install-exec-hook-<library> target whose role is to move the shared library from /usr/lib to /lib, while keeping a symbolic link /usr/lib/libuuid.so -> ../../lib/<library>.so.<version>. However, when util-linux is built with --enable-static --disable-shared (as is needed on noMMU platforms that don't support shared libraries), no <library>.so is built, but the install-exec-hook-libuuid creates an invalid /usr/lib/<library>.so symbolic link, pointing to ../../lib (yes, the directory). This causes troubles later one when other libraries/programs are compiled with -l<library>, as gcc thinks a shared library is available because there's a file named /usr/lib/<library>.so.

* libuuid: avoid double open and leaking fd (reworked)Petr Uzel2012-05-102-11/+19
| | | | | | | | | | | | | | 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>
* libuuid: avoid double open and leaking descriptorPetr Uzel2012-05-042-8/+11
| | | | | | | | | | | | | 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.
