[PATCH] kbuild: fix buffer overflow in modpost

2006-03-17T15:51:25Z

Jiri Benc reported that modpost would stop with SIGABRT if used with long filepaths. The error looked like: > Building modules, stage 2. > MODPOST > *** glibc detected *** scripts/mod/modpost: realloc(): invalid next size: +0x0809f588 *** > [...] Fix this by allocating at least the required memory + SZ bytes each time. Before we sometimes ended up allocating too little memory resuting in the glibc detected bug above.

kbuild: set correct KBUILD_MODNAME when using well known kernel symbols as module names

2005-12-25T23:33:41Z

This patch fixes a problem when we use well known kernel symbols as module names. For example, if module source name is current.c, idle_stack.c or etc., we have a bad KBUILD_MODNAME value. For example, KBUILD_MODNAME will be "get_current()" instead of "current", or "(init_thread_union.stack)" instead of "idle_task". The trick is to define a stringify macro on the commandline - named KBUILD_STR for namespace reasons - and then to stringify the module name. There are a few uses of KBUILD_MODNAME throughout the tree but the usage is for debug and will not be harmed by this change so left untouched for now. While at it KBUILD_BASENAME was changed too. Any spinlock usage in the unix module would have created wrong section names without it. Usage in spinlock.h fixed so it no longer stringify KBUILD_BASENAME. Original patch from Ustyogov Roman - all bugs introduced by me. Signed-off-by: Sam Ravnborg

kbuild: Fix crc-error warning on modules

2005-12-25T20:18:11Z

This is the patch for the following issue: In include/linux/module.h, "__crc_" and "__ksymtab_" are hard coded to be the prefix for some kinds of symbols (CRC symbol and ksymtab section). But in script /mod/modpost.c, MODULE_SYMBOL_PREFIX##"__crc_" is used as the prefix to search CRC symbols. So if an architecture (such as h8300 or Blackfin) defines MODULE_SYMBOL_PREFIX as not NULL ("_"), modpost will always warn about "no invalid crc". And it is the same with KSYMTAB_PFX.

[SPARC]: Fix dot-symbol exporting for good.

2005-09-12T03:14:07Z

From: Al Viro Instead of playing all of these hand-coded assembler aliasing games, just translate symbol names in the name space ".sym" to "_Sym" at module load time. Signed-off-by: David S. Miller

[SPARC]: Deal with glibc changing macro names in modpost.c

2005-08-19T20:44:57Z

GLIBC 2.3.4 and later changed the STT_REGISTER macro to STT_SPARC_REGISTER, so we need to cope with that somehow. Original patch from fabbione, reposted by Ben Collins. Signed-off-by: David S. Miller

Linux-2.6.12-rc2

2005-04-16T22:20:36Z

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!
