dump_write() analog, takes core_dump_params instead of file, keeps track of the amount written in cprm->written and checks for cprm->limit. Start using it in binfmt_elf.c... Signed-off-by: Al Viro

linux/coredump.h needs asm/siginfo.h

2012-10-19T21:07:47Z

Commit 5ab1c309b344 ("coredump: pass siginfo_t* to do_coredump() and below, not merely signr") added siginfo_t to linux/coredump.h but forgot to include asm/siginfo.h. This breaks the build for UML/i386. (And any other arch where asm/siginfo.h is not magically preincluded...)

coredump: pass siginfo_t* to do_coredump() and below, not merely signr

2012-10-05T18:05:16Z

This is a preparatory patch for the introduction of NT_SIGINFO elf note. With this patch we pass "siginfo_t *siginfo" instead of "int signr" to do_coredump() and put it into coredump_params. It will be used by the next patch. Most changes are simple s/signr/siginfo->si_signo/. Signed-off-by: Denys Vlasenko Reviewed-by: Oleg Nesterov Cc: Amerigo Wang Cc: "Jonathan M.

coredump: update coredump-related headers

2012-10-05T18:05:15Z

Create a new header file, fs/coredump.h, which contains functions only used by the new coredump.c. It also moves do_coredump to the include/linux/coredump.h header file, for consistency.

Un-inline the core-dump helper functions

2010-10-14T21:32:06Z

Tony Luck reports that the addition of the access_ok() check in commit 0eead9ab41da ("Don't dump task struct in a.out core-dumps") broke the ia64 compile due to missing the necessary header file includes. Rather than add yet another include () to make everything happy, just uninline the silly core dump helper functions and move the bodies to fs/exec.c where they make a lot more sense. dump_seek() in particular was too big to be an inline function anyway, and none of them are in any way performance-critical. And we really don't need to mess up our include file headers more than they already are. Reported-and-tested-by: Tony Luck Signed-off-by: Linus Torvalds

Don't dump task struct in a.out core-dumps

2010-10-14T17:57:40Z

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
