15 years agoThe attached patch addresses the problem with getting the audit daemon
Steve Grubb [Fri, 6 May 2005 11:38:39 +0000]
The attached patch addresses the problem with getting the audit daemon
shutdown credential information. It creates a new message type
AUDIT_TERM_INFO, which is used by the audit daemon to query who issued the
shutdown.

It requires the placement of a hook function that gathers the information. The
hook is after the DAC & MAC checks and before the function returns. Racing
threads could overwrite the uid & pid - but they would have to be root and
have policy that allows signalling the audit daemon. That should be a
manageable risk.

The userspace component will be released later in audit 0.7.2. When it
receives the TERM signal, it queries the kernel for shutdown information.
When it receives it, it writes the message and exits. The message looks
like this:

type=DAEMON msg=auditd(1114551182.000) auditd normal halt, sending pid=2650
uid=525, auditd pid=1685

[PATCH] ppc64: remove asm/bootinfo.h include

The defines in bootinfo.h are not used, so the include can be removed.
According to Ben, birecs are not used on ppc64:

  on ppc64, we made the decision of enforcing the presence of an
  OF device-tree and either an OF-like client interface or a kexec
  like flattened tree.
  so if your bootloader want to say things to the kernel,
  it can do so by adding properties to the device-tree

Paul Mackerras [Fri, 6 May 2005 03:29:34 +0000]
[PATCH] ppc64: fix prom.c compile warning

The code in unflatten_device_tree knows that get_property is written to
only return with lenp equal to 1 when also returning a valid pointer.
The gcc 3.3.3 compiler is not able to prove this to itself, so it warns
about a possible uninitialized pointer dereference:

 .../arch/ppc64/kernel/prom.c: In function `unflatten_device_tree':
 .../arch/ppc64/kernel/prom.c:828:
 warning: `p' might be used uninitialized in this function

Unless it is desired to rework the interaction between the two
functions, this will keep the existing behavior but quiet the compiler.

Manu Abraham [Thu, 5 May 2005 23:16:01 +0000]
[PATCH] bttv: fix dst i2c read/write timeout failure.

Attached is a patch to bttv which fixes the following problems.

Affected cards and problems:
~~~~~~~~~~~~~~~~~~~~~~~~
o VP-1020 (200103A) Tuning problems, device detection.
o VP-1020 (DST-MOT) Errors during tuning, device detection fails in a while.
o VP-1030 (DST-CI) Tuning sometimes fails after CI commands.
o VP-2031 (DCT-CI) Tuning problems

The timeout happens before the actual timeout occured in the MCU
on the board, and hence the problems.

Changes: (bttv-i2c.diff)
~~~~~~~~~~~~~~~~~~~~~~~~
o Changed the custom wait queue to wait_event_interruptible_timeout()
      - Suggestion by Johannes Stezenbach.

o Fixed the wait queue timeout problem
      - This fixes the timeout problem on various cards.
      - This problem was visible as many
          * Cannot tune to channels, when signal levels are very low.
          * app_info does not work in some conditions for CI based cards
      - Smaller values worked good for newer cards, but the older cards
suffered, settled down to the worst case values that could happen in any
eventuality.

Christoph Hellwig [Thu, 5 May 2005 23:15:58 +0000]
[PATCH] DAC960: add support for Mylex AcceleRAID 4/5/600

This patch adds support for a new class of DAC960 controllers.  It's based
on the GPLed idac320 driver from IBM for Linux 2.4.18.  That driver is a
fork of the 2.4.18 version of DAC960 that adds support for this new type of
controllers (internally called "GEM Series"), that differ from other DAC960
V2 firmware controllers only in the register offsets and removes support
for all others.

This patch instead integrates support for these controllers into the DAC960
driver.

Thanks to Anders Norrbring for pointing me to the idac320 driver and
testing this patch.

No Signed-Off: line because all code is either copy & pasted from IBM's
idac320 driver or support for other controllers in the 2.6 DAC960 driver.

Note: the really odd formating matches the rest of the DAC960 driver.

15 years ago[PATCH] setitimer timer expires too early
Paulo Marques [Thu, 5 May 2005 23:15:49 +0000]
[PATCH] setitimer timer expires too early

It seems that the code responsible for this is in kernel/itimer.c:126:

p->signal->real_timer.expires = jiffies + interval;
add_timer(&p->signal->real_timer);

If you request an interval of, lets say 900 usecs, the interval given by
timeval_to_jiffies will be 1.

If you request this when we are half-way between two timer ticks, the
interval will only give 400 usecs.

If we want to guarantee that we never ever give intervals less than
requested, the simple solution would be to change that to:

p->signal->real_timer.expires = jiffies + interval + 1;

This however will produce pathological cases, like having a idle system
being requested 1 ms timeouts will give systematically 2 ms timeouts,
whereas currently it simply gives a few usecs less than 1 ms.

The complex (and more computationally expensive) solution would be to
check the gettimeofday time, and compute the correct number of jiffies.
This way, if we request a 300 usecs timer 200 usecs inside the timer
tick, we can wait just one tick, but not if we are 800 usecs inside the
tick. This would also mean that we would have to lock preemption during
these computations to avoid races, etc.

I've searched the archives but couldn't find this particular issue being
discussed before.

Attached is a patch to do the simple solution, in case anybody thinks
that it should be used.

[PATCH] __block_write_full_page race fix

When running
fsstress -v -d $DIR/tmp -n 1000 -p 1000 -l 2
on an ext2 filesystem with 1024 byte block size, on SMP i386 with 4096 byte
page size over loopback to an image file on a tmpfs filesystem, I would
very quickly hit
BUG_ON(!buffer_async_write(bh));
in fs/buffer.c:end_buffer_async_write

It seems that more than one request would be submitted for a given bh
at a time.

What would happen is the following:
2 threads doing __mpage_writepages on the same page.
Thread 1 - lock the page first, and enter __block_write_full_page.
Thread 1 - (eg.) mark_buffer_async_write on the first 2 buffers.
Thread 1 - set page writeback, unlock page.
Thread 2 - lock page, wait on page writeback
Thread 1 - submit_bh on the first 2 buffers.
=> both requests complete, none of the page buffers are async_write,
   end_page_writeback is called.
Thread 2 - wakes up. enters __block_write_full_page.
Thread 2 - mark_buffer_async_write on (eg.) the last buffer
Thread 1 - finds the last buffer has async_write set, submit_bh on that.
Thread 2 - submit_bh on the last buffer.
=> oops.

So change __block_write_full_page to explicitly keep track of the last bh
we need to issue, so we don't touch anything after issuing the last
request.

to thread.arch.faultinfo with one simple assignment.

Also, the number of macros necessary is reduced to

FAULT_ADDRESS(struct faultinfo)
    extracts the faulting address from faultinfo

FAULT_WRITE(struct faultinfo)
    extracts the "is_write" flag

SEGV_IS_FIXABLE(struct faultinfo)
    is true for the fixable segvs, i.e. (TRAP == 14)
    on i386

UPT_FAULTINFO(regs)
    result is (struct faultinfo *) to the faultinfo
    in regs->skas.faultinfo

GET_FAULTINFO_FROM_SC(struct faultinfo, struct sigcontext *)
    copies the relevant parts of the sigcontext to
    struct faultinfo.

On SIGSEGV, call user_signal() instead of handle_segv(), if the architecture
provides the information needed in PTRACE_FAULTINFO, or if PTRACE_FAULTINFO is
missing, because segv-stub will provide the info.

The benefit of the change is, that in case of a non-fixable SIGSEGV, we can
give user processes a SIGSEGV, instead of possibly looping on pagefault
handling.

Since handle_segv() sikked arch_fixup() implicitly by passing ip==0 to segv(),
I changed segv() to call arch_fixup() only, if !is_user.

Beginning of cross-build fixes.  Instead of expecting that mk_user_constants

box, we do what every architecture already does for asm-offsets.  Namely, have

This patch deals with mk_user_constants.  It doesn't assume any relationship
between target and build environment anymore - we pick all defines we need
from user-offsets.h.  Later patches will deal with the rest of mk_...  helpers

Paolo 'Blaisorblade' Giarrusso [Thu, 5 May 2005 23:15:17 +0000]
[PATCH] x86_64: make string func definition work as intended

In include/asm-x86_64/string.h there are such comments:

/* Use C out of line version for memcmp */
#define memcmp __builtin_memcmp
int memcmp(const void * cs,const void * ct,size_t count);

This would mean that if the compiler does not decide to use __builtin_memcmp,
it emits a call to memcmp to be satisfied by the C out-of-line version in
lib/string.c.  What happens is that after preprocessing, in lib/string.i you
may find the definition of "__builtin_strcmp".

Actually, by accident, in the object you will find the definition of strcmp
and such (maybe a trick intended to redirect calls to __builtin_memcmp to the
default memcmp when the definition is not expanded); however, this particular
case is not a documented feature as far as I can see.

Also, the EXPORT_SYMBOL does not work, so it's duplicated in the arch.

I simply added some #undef to lib/string.c and removed the (now duplicated)
exports in x86-64 and UML/x86_64 subarchs (the second ones are introduced by
another patch I just posted for -mm).

- Abolishing never-used macros
- Eliminating multiple #defines with the same purpose
- Removing pointless macros (cases where just expanding the
macro everywhere turns out clearer and more sensible)
- Removing some cases where macros which could be defined in
terms of each other weren't
- Moving imalloc() related definitions from pgtable.h to their
own header file (imalloc.h)
- Re-arranging headers to group things more logically
- Moving all VSID allocation related things to mmu.h, instead
of being split between mmu.h and mmu_context.h
- Removing some reserved space for flags from the PMD - we're

15 years ago[PATCH] x86 stack initialisation fix
Alexander Nyberg [Thu, 5 May 2005 23:15:03 +0000]
[PATCH] x86 stack initialisation fix

The recent change fix-crash-in-entrys-restore_all.patch

  childregs->esp = esp;

  p->thread.esp = (unsigned long) childregs;
- p->thread.esp0 = (unsigned long) (childregs+1);
+ p->thread.esp0 = (unsigned long) (childregs+1) - 8;

  p->thread.eip = (unsigned long) ret_from_fork;

introduces an inconsistency between esp and esp0 before the task is run the
first time.  esp0 is no longer the actual start of the stack, but 8 bytes
off.

This shows itself clearly in a scenario when a ptracer that is set to also
ptrace eventual children traces program1 which then clones thread1.  Now
the ptracer wants to modify the registers of thread1.  The x86 ptrace
implementation bases it's knowledge about saved user-space registers upon
p->thread.esp0.  But this will be a few bytes off causing certain writes to
the kernel stack to overwrite a saved kernel function address making the
kernel when actually running thread1 jump out into user-space.  Very
spectacular.

The testcase I've used is:
/* start with strace -f ./a.out */
#include <pthread.h>
#include <stdio.h>

void *do_thread(void *p)
{
for (;;);
}

int main()
{
pthread_t one;
pthread_create(&one, NULL, &do_thread, NULL);
for (;;);
return 0;
}

So, my solution is to instead of just adjusting esp0 that creates an
inconsitent state I adjust where the user-space registers are saved with -8
bytes.  This gives us the wanted extra bytes on the start of the stack and
esp0 is now correct.  This solves the issues I saw from the original
testcase from Mateusz Berezecki and has survived testing here.  I think
this should go into -mm a round or two first however as there might be some
cruft around depending on pt_regs lying on the start of the stack.  That
however would have broken with the first change too!

It's actually a 2-line diff but I had to move the comment of why the -8 bytes
are there a few lines up. Thanks to Zwane for helping me with this.

15 years ago[PATCH] Kconfig i18n support
Arnaldo Carvalho de Melo [Thu, 5 May 2005 22:09:46 +0000]
[PATCH] Kconfig i18n support

This patch adds i18n support for make *config, allowing users to have the
config process in their own language.

No printk was harmed in the process, don't worry, so all the bug reports,
kernel messages, etc, remain in english, just the user tools to configure
the kernel are internationalized.

Users not interested in translations can just unset the related LANG,
LC_ALL, etc env variables and have the config process in plain english,
something like:

LANG= make menuconfig

is enough for having the whole config process in english. Or just don't
install any translation file.

Translations for brazilian portuguese are being done by a team of
volunteers at:

http://www.visionflex.inf.br/kernel_ptbr/pmwiki.php/Principal/Traducoes

To start the translation process:

  make update-po-config

  This will generate the pot template named scripts/kconfig/linux.pot,
  copy it to, say, ~/es.po, to start the translation for spanish.

To test your translation, as root issue this command:

  msgfmt -o /usr/share/locale/es/LC_MESSAGES/linux.mo ~/es.po

  Replace "es" with your language code.

  Then execute, for instance:

  make menuconfig

The current patch doesn't use any optimization to reduce the size of the
generated .mo file, it is possible to use the config option as a key, but
this doesn't prevent the current patch from being used or the translations
done under the current scheme to be in any way lost if we chose to do any
kind of keying.

Thanks to Fabricio Vaccari for starting the pt_BR (brazilian portuguese)
translation effort, Thiago Maciera for helping me with the gconf.cc (QT
frontent) i18n coding and to all the volunteers that are already working on
the first translation, to pt_BR.

I left the question on whether to ship the translations with the stock kernel
sources to be discussed here, please share your suggestions.
