cpupower: Fix segfault due to incorrect getopt_long arugments

2014-01-08T17:42:11+00:00

commit f447ef4a56dee4b68a91460bcdfe06b5011085f2 upstream. If a user calls 'cpupower set --perf-bias 15', the process will end with a SIGSEGV in libc because cpupower-set passes a NULL optarg to the atoi call. This is because the getopt_long structure currently has all of the options as having an optional_argument when they really have a required argument. We change the structure to use required_argument to match the short options and it resolves the issue.

kbuild: Fix gcc -x syntax

2012-10-12T20:38:37+00:00

commit b1e0d8b70fa31821ebca3965f2ef8619d7c5e316 upstream. The correct syntax for gcc -x is "gcc -x assembler", not "gcc -xassembler". Even though the latter happens to work, the former is what is documented in the manual page and thus what gcc wrappers such as icecream do expect. This isn't a cosmetic change. The missing space prevents icecream from recognizing compilation tasks it can't handle, leading to silent kernel miscompilations. Besides me, credits go to Michael Matz and Dirk Mueller for investigating the miscompilation issue and tracking it down to this incorrect -x parameter syntax.

cpupower tool: allow to build in a separate directory

2012-03-03T13:40:10+00:00

This patch allows cpupower tool to generate its output files in a seperate directory. This is now possible by passing the 'O=' to the command line. This can be usefull for a normal user if the kernel source code is located in a read only location. This is patch stole some bits of the perf makefile.

cpupower tool: makefile: simplify the recipe used to generate cpupower.pot target

2012-03-03T13:40:10+00:00

Use the '-p' and '-o' switches to specify the pathname of the output file to xgettext(1). This avoids to move manually the output file if xgettext(1) succeeds. Signed-off-by: Franck Bui-Huu Signed-off-by: Dominik Brodowski

2012-03-03T13:40:10+00:00

UTIL_BINS and IDLE_OBJS variables are not defined at all, so there's no need to remove their content from the 'clean' target. Signed-off-by: Franck Bui-Huu Signed-off-by: Dominik Brodowski

cpupower: Remove unneeded code and by that fix a memleak

2012-03-03T13:40:10+00:00

Looks like some not needed debug code slipped in. Also this code: tmp = sysfs_get_idlestate_name(cpu, idlestates - 1); performs a strdup and the mem was not freed again. -> delete it. Signed-off-by: Thomas Renninger Signed-off-by: Dominik Brodowski
