2011-09-29lib: [strutils] add strtod_or_err() functionSami Kerola1-0/+24
Signed-off-by: Sami Kerola <kerolasa@iki.fi>
2011-09-27lib,loopdev: fix use of logical '&&' with constant operandFrancesco Cosoleto1-2/+2
Found by clang. Signed-off-by: Francesco Cosoleto <cosoleto@gmail.com>
2011-09-27lib,path: use write_all()Heiko Carstens1-1/+2
From: Heiko Carstens <heiko.carstens@de.ibm.com> Since write() doesn't necessarily write the complete buffer with one call we better use write_all() which takes care of this. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com>
2011-09-27chcpu: convert to use lib/path.cHeiko Carstens1-0/+26
Use the common path access functions. In order to simplify chcpu also implement and use path_writestr() which writes a string to the path specified. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com>
2011-09-27lib,path: move path access functions from lscpu into lib/path.cHeiko Carstens1-0/+191
A couple of these functions already have been copied to chcpu.c, so it makes sense to move these functions into an own file. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com>
2011-09-13lib: do not attempt to close(0) in sysfs_deinit()Petr Uzel1-0/+1
If the 'open' fails we 'goto err' which runs 'sysfs_deinit()' on a 'cxt' which hasn't been fully initialised. The 'dir_fd' is still 0, so sysfs_deinit calls "close(0)".

2011-09-10chcpu,cpuset: reduce code duplication for cpu list parsingHeiko Carstens1-1/+6
Reduce code duplication and print better error message if an unsupported cpu number was passed. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com>
2011-09-10lib,cpuset: enforce stricter parsing of cpu listsHeiko Carstens1-4/+8
The current cpulist_parse() function ignores extra non-parsable characters at the end of the to be parsed cpu list string. E.g. it would accept something like "0bla" and just set bit 0 in the cpu set. Since such a string is invalid implement stricter parsing that makes sure that everything of the string has been succesfully parsed. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com>
2011-09-10lib,cpuset: fix stride handling in cpulist_parse()Heiko Carstens1-0/+2
If cpulist_parse() gets passed a cpu list with a stride value of 0 it will be stuck in an endless loop. E.g. the following cpu list will cause an endless loop: "0-2:0". Fix this by causing a parse error if the stride value is 0. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com>
2011-09-10lib,cpuset: fix odd placed braces in cpulist_parse()Heiko Carstens1-2/+2
The opening and closing braces for two following if statements within cpulist_parse() are placed in an odd manner. Just fix this to prevent broken code in the future. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com>
2011-09-10lib,cpuset: fix comments for cpu mask/list functionsHeiko Carstens1-2/+2
The comments for cpumask_parse() and cpulist_parse() each describe the wrong function. Just exchange the comments. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com>

2011-08-15cpuset: add option to allow cpulist_parse() to failHeiko Carstens1-2/+5
This is a preparation patch for chcpu. If a cpu should be added to a cpu_set where the cpu doesn't fit into the cpu_set this got silently ignored. Since the cpu-list is user space provided it should be checked if cpus are specified that are completely out of range of the system. In order to do that add a parameter which specifies if cpulist_parse() should fail if it parses a cpu-list with "impossible" cpus. The current callers have been converted so they behave like before.
