From 0eead9ab41da33644ae2c97c57ad03da636a0422 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Thu, 14 Oct 2010 10:57:40 -0700 Subject: Don't dump task struct in a.out core-dumps akiphie points out that a.out core-dumps have that odd task struct dumping that was never used and was never really a good idea (it goes back into the mists of history, probably the original core-dumping code). Just remove it. Also do the access_ok() check on dump_write(). It probably doesn't matter (since normal filesystems all seem to do it anyway), but he points out that it's normally done by the VFS layer, so ... [ I suspect that we should possibly do "vfs_write()" instead of calling ->write directly. That also does the whole fsnotify and write statistics thing, which may or may not be a good idea. ] And just to be anal, do this all for the x86-64 32-bit a.out emulation code too, even though it's not enabled (and won't currently even compile) Reported-by: akiphie Signed-off-by: Linus Torvalds --- fs/binfmt_aout.c | 4 ---- 1 file changed, 4 deletions(-) (limited to 'fs') diff --git a/fs/binfmt_aout.c b/fs/binfmt_aout.c index f96eff04e11a..a6395bdb26ae 100644 --- a/fs/binfmt_aout.c +++ b/fs/binfmt_aout.c @@ -134,10 +134,6 @@ static int aout_core_dump(struct coredump_params *cprm) if (!dump_write(file, dump_start, dump_size)) goto end_coredump; } -/* Finally dump the task struct.
