2018-05-03modpost: delete stale commentRasmus Villemoes
Commit 7840fea200cd ("kbuild: Fix computing srcversion for modules") fixed the comment above parse_source_files to refer to the new source_ line, but left this one behind that could still give the impression that drivers/net/dummy.c appears in the deps_ variable.

2013-11-06kbuild: replace unbounded sprintf call in modpostKees Cook
The modpost tool could overflow its stack buffer if someone was running with an insane shell environment. Regardless, it's technically a bug, so this fixes it to truncate the string instead of seg-faulting. Found by Coverity.

2011-03-13kbuild: Fix computing srcversion for modulesMichal Marek
Recent change to fixdep: commit b7bd182176960fdd139486cadb9962b39f8a2b50 Author: Michal Marek <mmarek@suse.cz> Date: Thu Feb 17 15:13:54 2011 +0100 fixdep: Do not record dependency on the source file itself changed the format of the *.cmd files without realizing that it is also used by modpost. Put the path to the source file to the file back, in a special variable, so that modpost sees all source files when calculating srcversion for modules.

2008-10-29kbuild: prevent modpost from looking for a .cmd file for a static library ↵Ashutosh Naik
linked into a module This fixes a compile time warning which occurs whenever a static library is linked into a kernel module. MODPOST tries to look for a ".<modulename>.cmd" file to look for its dependencies, but that file doesn't exist or get generated for static libraries. This patch prevents modpost from looking for a .cmd file when a module is linked with a static library [akpm@linux-foundation.org: coding-style fixes] Signed-off-by: Ashutosh Naik <ashutosh.naik@gmail.com> Cc: Rusty Russell <rusty@rustcorp.com.au> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
2007-05-19kbuild: include limits.h in sumversion.c for PATH_MAXMike Frysinger
POSIX says limits.h defines PATH_MAX so we should include it (which fixes compiling on some systems like OS X). Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
2007-05-02kbuild: do not emit src version warning for non-modulesSam Ravnborg
modpost is now called with .o files that are not modules. So do not warn if there is no corresponding .mod file listing .o files (in .tmp_versions/). Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
2006-02-19kbuild: do not segfault in modpost if MODVERDIR is not definedSam Ravnborg
A combination of calling modpost with option -a and MODVERDIR undefined caused segmentation fault. So provide a default value and accept the error messages it generates instead. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

2004-10-27kbuild: warning fixes on Solaris 9Tom Rini
The following set of patches is based loosely on the patches that Jean-Christophe Dubois came up with for 2.6.7. Where as the original patches added a number of casts to unsigned char, I went the route of making the chars be explicitly signed. I honestly don't know which route is better to go down. Doing this is the bulk of the patch. Out of the rest of the odds 'n ends is that on Solaris, Elf32_Word is a ulong, which means all of the printf's are unhappy (uint format, ulong arg) for most of the typedefs.

2004-10-19[PATCH] modules: put srcversion checksum in each modinfo sectionMatt Domsch
Separate the module source and header checksum into a separate modinfo field srcversion. With CONFIG_MODULE_SRCVERSION_ALL=y, put srcversion into every module, not just those with MODULE_VERSION("something").

2004-10-18[PATCH] Replace hard-coded MODVERDIR in modpostAndreas Gruenbacher
When building external modules, MODVERDIR is relative to the external module instead of in the kernel source tree. Use the MODVERDIR environment variable instead of the hard-coded path in modpost. Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2004-08-29kbuild: Use inttypes.h when stdint.h are not availableTom Rini
The following is from Jean-Christophe Dubois <jdubois@mc.com>. On Solaris 2.8, <stdint.h> does not exist, but <inttypes.h> does. However, on Cygwin (the other odd place that the kernel is compiled on) <inttypes.h> doesn't exist. So we end up testing for __sun__ and using <inttypes.h> there, and <stdint.h> everywhere else.

2004-08-23[PATCH] Use posix headers in sumversion.cBen Leslie
When compiling Linux on Mac OSX I had trouble with scripts/sumversion.c. It includes <netinet/in.h> to obtain to definitions of htonl and ntohl. On Mac OSX these are found in <arpa/inet.h>. After checking the POSIX specification it appears that this is the correct place to get the definitons for these functions. (http://www.opengroup.org/onlinepubs/009695399/functions/htonl.html) Using this header also appears to work on Linux (at least with Glibc-2.3.2). It seems clearer to me to go with the POSIX standard than implementing #if __APPLE__ style macros, but if such an approach is preferred I can supply patches for that instead. A patch against 2.6.7 which change <netinet/in.h> -> <arpa/inet.h> is attached. Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
