2017-06-24lib/cmdline.c: fix get_options() overflow while parsing rangesIlya Matveychikov1-3/+3
When using get_options() it's possible to specify a range of numbers, like 1-100500. The problem is that it doesn't track array size while calling internally to get_range() which iterates over the range and fills the memory with numbers.

2017-04-18boot/param: Move next_arg() function to lib/cmdline.c for later reuseBaoquan He1-0/+57
next_arg() will be used to parse boot parameters in the x86/boot/compressed code, so move it to lib/cmdline.c for better code reuse. No change in functionality.

2014-10-03lib: Add a generic cmdline parse function parse_option_strDave Young1-0/+29
There should be a generic function to parse params like a=b,c Adding parse_option_str in lib/cmdline.c which will return true if there's specified option set in the params. Also updated efi=old_map parsing code to use the new function Signed-off-by: Dave Young <dyoung@redhat.com> Signed-off-by: Matt Fleming <matt.fleming@intel.com>

2012-03-08lib: reduce the use of module.h wherever possiblePaul Gortmaker1-1/+1
For files only using THIS_MODULE and/or EXPORT_SYMBOL, map them onto including export.h -- or if the file isn't even using those, then just delete the include. Fix up any implicit include dependencies that were being masked by module.h along the way. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>

2008-07-25lib: allow memparse() to accept a NULL and ignorable second parmRobert P. J. Day1-5/+11
Extend memparse() to allow the caller to use a NULL second parameter, which would represent no interest in returning the address of the end of the parsed string. In numerous cases, callers invoke memparse() to parse a possibly-suffixed string (such as "64K" or "2G" or whatever) and define a character pointer to accept the end pointer being returned by memparse() even though they have no interest in it and promptly throw it away. This (backward-compatible) enhancement allows callers to use NULL in the cases where they just don't care about getting back that end pointer.

2006-12-07[PATCH] get_options to allow a hypenated range for isolcpusDerek Fults1-1/+34
This allows a hyphenated range of positive numbers in the string passed to command line helper function, get_options. Currently the command line option "isolcpus=" takes as its argument a list of cpus. Format: <cpu number>,...,<cpu number> Valid values of <cpu_number> include all cpus, 0 to "number of CPUs in system - 1". This can get extremely long when isolating the majority of cpus on a large system. The kernel isolcpus code would not need any changing to use this feature. To use it, the change would be in the command line format for 'isolcpus=' Format: <cpu number>,...,<cpu number> or <cpu number>-<cpu number> (must be a positive range in ascending order.) or a mixture <cpu number>,...,<cpu number>-<cpu number> Signed-off-by: Derek Fults <dfults@sgi.com> Cc: "Randy.Dunlap" <rdunlap@xenotime.net> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-04-17Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds1-0/+120
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
