[PATCH] kbuild: fix modpost segfault for 64bit mipsel kernel

2006-05-21T19:59:21+00:00

Here is an updated r_info layout fix.  Please apply "check SHT_REL
sections" patch before this.

64bit mips has different r_info layout.  This patch fixes modpost
segfault for 64bit little endian mips kernel.

[PATCH] kbuild: check SHT_REL sections

2006-05-21T19:59:21+00:00

I found that modpost can not detect section mismatch on mips and i386.  On
mips64, the modpost (with r_info layout fix) can detect it.  The current
modpst only checks SHT_RELA section but I suppose SHT_REL section should be
checked also.  This patch does not contain r_info layout fix.  I'll post an
updated r_info layout fix on next mail.

Check SHT_REL sections as like as SHT_RELA sections to detect section
mismatch.

Revert "kbuild: fix modpost segfault for 64bit mipsel kernel"

2006-05-08T20:38:42+00:00

This reverts commit c8d8b837ebe4b4f11e1b0c4a2bdc358c697692ed, which
caused problems for the x86 build. Quoth Sam:

  "It was discussed on mips list but apparently the fix was bogus.  I
   will not have time to look into it so mips can carry this local fix
   until we get a proper fix in mainline."

kbuild modpost - relax driver data name

Relax driver data name from *_driver to *driver.
This fixes the 26 section mismatch warnings in drivers/ide/pci.

kbuild: fix false section mismatch warnings

2006-04-14T22:35:22+00:00

Darren Jenkins  pointed out a
number of false positives where we referenced variables
from a _driver variable.
Fix it by check for that pattern and ignore it.

Randy.Dunlap  pointed out a similar
set of warnings for a number of scsi drivers.
In scsi world they misname their variables *_template or
*_sht so add these to list of variables that may have references
to .init.text with no warning.

Randy.Dunlap  also pointed out a scsi driver
with many references to .exit.text from .rodata. This is compiler
generated references and we already ignore these for .init.text, so
ignore them for .exit.text also.

kbuild: fix NULL dereference in scripts/mod/modpost.c

2006-04-11T11:37:07+00:00

before is NULL in this case, concluding from the surrounding code
it seems that after is the right one to use.

[PATCH] kbuild: fix buffer overflow in modpost

2006-03-17T15:51:25+00:00

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.  Based on patch originally submitted by: Jiri
Benc

kbuild: Fix bug in crc symbol generating of kernel and modules

2006-03-08T17:33:16+00:00

The scripts/genksyms/genksyms.c uses hardcoded "__crc_" prefix for
crc symbols in kernel and modules. The prefix should be replaced by
"MODULE_SYMBOL_PREFIX##__crc_" otherwise there will be warnings when
MODULE_SYMBOL_PREFIX is not NULL.

I am sorry my last patch for this issue is actually wrong. I revert
it in this patch.
