From: Jeff Dike <jdike@addtoit.com>, Paolo 'Blaisorblade' Giarrusso <blaisorblade@yahoo.it> Revert the following patch, because of miscompilation problems in different environments leading to UML not working *at all* in TT mode; it was merged lately in 2.6 development cycle, a little after being written, and has caused problems to lots of people; I know it's a bit too long, but it shouldn't have been merged in first place, so I still apply for inclusion in the -stable tree. Anyone using this feature currently is either using some older kernel (some reports even used 2.6.12-rc4-mm2) or using this patch, as included in my -bs patchset. For now there's not yet a fix for this patch, so for now the best thing is to drop it (which was widely reported to give a working kernel). "Convert the boot-time host ptrace testing from clone to fork. They were essentially doing fork anyway. This cleans up the code a bit, and makes valgrind a bit happier about grinding it."

We add a check of the return value of tty_ldisc_ref(), which is checked 7 out of 8 times, e.g.: 149 ld = tty_ldisc_ref(tty); 150 if (ld != NULL) { 151 if (ld->set_termios) 152 (ld->set_termios)(tty, &old_termios); 153 tty_ldisc_deref(ld); 154 } This defect was found automatically by Coverity Prevent, a static analysis tool. (akpm: presumably `ld' is never NULL. Oh well) Signed-off-by:Zaur Kambarov <zkambarov@coverity.com> Acked-by:

A problem was reported that the tpm driver was interfereing with networking on the 8139 chipset. The tpm driver was using a hard coded the memory address instead of the value the BIOS was putting the chip at. This was in the tpm_lpc_bus_init function. That function can be replaced with querying the value at Vendor specific locations. This patch replaces all calls to tpm_lpc_bus_init and the hardcoding of the base address with a lookup of the address at the correct vendor location. Signed-off-by:

As part of my timeofday rework, I've been looking at the NTP code and I noticed that the PPC architecture is apparently misusing the NTP's time_offset (it is a terrible name!) value as some form of timezone offset. This could cause problems when time_offset changed by the NTP code. This patch changes the PPC code so it uses a more clear local variable: timezone_offset. Signed-off-by:

1) netlink_release() should only decrement the hash entry count if the socket was actually hashed. This was causing hash->entries to underflow, which resulting in all kinds of troubles. On 64-bit systems, this would cause the following conditional to erroneously trigger: err = -ENOMEM; if (BITS_PER_LONG > 32 && unlikely(hash->entries >= UINT_MAX)) goto err; 2) netlink_autobind() needs to propagate the error return from netlink_insert(). Otherwise, callers will not see the error as they should and thus try to operate on a socket with a zero pid, which is very bad. However, it should not propagate -EBUSY. If two threads race to autobind the socket, that is fine. This is consistent with the autobind behavior in other protocols. So bug #1 above, combined with this one, resulted in hangs on netlink_sendmsg() calls to the rtnetlink socket. We'd try to do the user sendmsg() with the socket's pid set to zero, later we do a socket lookup using that pid (via the value we stashed away in NETLINK_CB(skb).pid), but that won't give us the user socket, it will give us the rtnetlink socket. So when we try to wake up the receive queue, we dive back into rtnetlink_rcv() which tries to recursively take the rtnetlink semaphore. Thanks to Jakub Jelink for providing backtraces. Also, thanks to Herbert Xu for supplying debugging patches to help track this down, and also finding a mistake in an earlier version of this fix. Signed-off-by:

Add "memory" clobbers to the x86 inline asm of strncmp and friends They don't actually clobber memory, but gcc doesn't even know they _read_ memory, so can apparently re-order memory accesses around them. Which obviously does the wrong thing if the memory access happens to change the memory that the compare function is accessing.. Verified to fix a strange boot problem by Jens Axboe. Signed-off-by: -

__cfq_get_queue(). __cfq_get_queue() finds an existing queue (struct cfq_queue) of the current process for the device and returns it. If it's not found, __cfq_get_queue() creates and returns a new one if __cfq_get_queue() is called with __GFP_WAIT flag, or __cfq_get_queue() returns NULL (this means that get_request() fails) if no __GFP_WAIT flag. On the other hand, in __make_request(), get_request() is called without __GFP_WAIT flag at the first time. Thus, the get_request() fails when there is no existing queue, typically when it's called for the first I/O request of the process to the device. Though it will be followed by get_request_wait() for general case, __make_request() will just end the I/O with an error (EWOULDBLOCK) when the request was for read-ahead. Signed-off-by:

The ELF core dump code has one use of off_t when writing out segments. Some of the segments may be passed the 2GB limit of an off_t, even on a 32-bit system, so it's important to use loff_t instead. This fixes a corrupted core dump in the bigcore test in GDB's testsuite. Signed-off-by:

This fixed a problem that showed up in the Fedora development tree a few weeks before the Fedora Core 4 release, initially as slab corruption, later as hard crashes on boot up, when slab debugging was disabled for the release. More details on the history at https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=158424 The problem is caused by sbp2's use of scsi_host->hostdata[0] to hold a scsi_id, without explicitly requesting space for it. Since hostdata is declared as a zero-sized array, we don't get any such space by default, so it must be explicitly requested. The patch below implements just that. Signed-off-by:
