This reverts commit a069c266. It turns ou that not only was it missing a case (XFS) that needed it, but perhaps more importantly, people sometimes want to enable new modules that they hadn't had enabled before, and if such a module uses list_sort(), it can't easily be inserted any more. So rather than add a "select LIST_SORT" to the XFS case, just leave it compiled in. It's not all _that_ big, after all, and the inconvenience isn't worth it. Requested-by:

This adds separate I/O and memory specs, so we don't have to change the field width in a shared spec, which then lets us make all the specs const and static, since they never change. Signed-off-by:

Reducing the size of struct printf_spec is a good thing because multiple instances are commonly passed on stack. It's possible for type to be u8 and field_width to be s8, but this is likely small enough for now. Signed-off-by:

The caller of usbfs_conn_disc_event() in some cases (but not always) already holds usbfs_mutex, so trying to protect the event counter with that lock causes nasty deadlocks. The problem was introduced by commit 554f7696 ("USB: Remove BKL from poll()") when the BLK protection was turned into using the mutex instead. So fix this by using an atomic variable instead. And while we're at it, get rid of the atrocious naming of said variable and the waitqueue it is associated with. This also cleans up the unnecessary locking in the poll routine, since the whole point of how the pollwait table works is that you can just add yourself to the waiting list, and then check the condition you're waiting for afterwards - avoiding all races. It also gets rid of the unnecessary dynamic allocation of the device status that just contained a single word. We should use f_version for this, as Dmitry Torokhov points out. That simplifies everything further. Reported-and-tested-by:

The cs5535-gpio driver's get() function was returning the output value. This means that the GPIO pins would never work as an input, even if configured as an input. The driver should return the READ_BACK value, which is the sensed line value. To make that work when the direction is 'output', INPUT_ENABLE needs to be set. In addition, the driver was not disabling OUTPUT_ENABLE when the direction is set to 'input'. That would cause the GPIO to continue to drive the pin if the direction was ever set to output. This issue was noticed when attempting to use the gpiolib driver to read an external input. I had previously been using the char/cs5535-gpio driver. Signed-off-by:

Modify uid check in do_coredump so as to not apply it in the case of pipes. This just got noticed in testing. The end of do_coredump validates the uid of the inode for the created file against the uid of the crashing process to ensure that no one can pre-create a core file with different ownership and grab the information contained in the core when they shouldn' tbe able to. This causes failures when using pipes for a core dumps if the crashing process is not root, which is the uid of the pipe when it is created. The fix is simple. Since the check for matching uid's isn't relevant for pipes (a process can't create a pipe that the uermodehelper code will open anyway), we can just just skip it in the event ispipe is non-zero Reverts a pipe-affecting change which was accidentally made in : commit c46f739d : Author: Ingo Molnar <mingo@elte.hu> : AuthorDate: Wed Nov 28 13:59:18 2007 +0100 : Commit: Linus Torvalds <torvalds@woody.linux-foundation.org> : CommitDate: Wed Nov 28 10:58:01 2007 -0800 : : vfs: coredumping fix Signed-off-by:

User visible change. do_coredump() kills all threads which share the same ->mm but only the coredumping process gets the proper exit_code. Other tasks which share the same ->mm die "silently" and return status == 0 to parent. This is historical behaviour, not actually a bug. But I think Frank Heckenbach rightly dislikes the current behaviour. Simple test-case: #include <stdio.h> #include <unistd.h> #include <signal.h> #include <sys/wait.h> int main(void) { int stat; if (!fork()) { if (!vfork()) kill(getpid(), SIGQUIT); } wait(&stat); printf("stat=%x\n", stat); return 0; } Before this patch it prints "stat=0" despite the fact the child was killed by SIGQUIT. After this patch the output is "stat=3" which obviously makes more sense. Even with this patch, only the task which originates the coredumping gets "|= 0x80" if the core was actually dumped, but at least the coredumping signal is visible to do_wait/etc. Reported-by:Frank Heckenbach <f.heckenbach@fh-soft.de> Signed-off-by:

To solve this issue, this patch copies mm->flags to coredump_params.mm_flags at the beginning of do_coredump() and uses it instead of get_dumpable() while dumping core. This copy is also passed to binfmt->core_dump, since elf*_core_dump() uses dump_filter bits in mm->flags.

The current ELF dumper implementation can produce broken corefiles if program headers exceed 65535. This number is determined by the number of vmas which the process have. In particular, some extreme programs may use more than 65535 vmas. (If you google max_map_count, you can find some users facing this problem.) This kind of program never be able to generate correct coredumps. This patch implements ``extended numbering'' that uses sh_info field of the first section header instead of e_phnum field in order to represent upto 4294967295 vmas. This is supported by AMD64-ABI(http://www.x86-64.org/documentation.html) and Solaris(http://docs.sun.com/app/docs/doc/817-1984/). Of course, we are preparing patches for gdb and binutils.

By the next patch, elf_core_dump() and elf_fdpic_core_dump() will support extended numbering and so will produce the corefiles with section header table in a special case. The problem is the process of writing a file header offset of the section header table into e_shoff field of the ELF header. ELF header is positioned at the beginning of the corefile, while section header at the end. So, we need to take which of the following ways: 1. Seek backward to retry writing operation for ELF header after writing process for a whole part 2. Make offset calculation process and writing process totally sequential The clause 1. is not always possible: one cannot assume that file system supports seek function. Consider the no_llseek case. Therefore, this patch adopts the clause 2. Signed-off-by: -

elf_core_dump() and elf_fdpic_core_dump() use #ifdef and the corresponding macro for hiding _multiline_ logics in functions. This patch removes #ifdef and replaces ELF_CORE_EXTRA_* by corresponding functions. For architectures not implemeonting ELF_CORE_EXTRA_*, we use weak functions in order to reduce a range of modification. This cleanup is for my next patches, but I think this cleanup itself is worth doing regardless of my firnal purpose. Signed-off-by:
