2007-10-01[TCP]: secure_tcp_sequence_number() should not use a too fast clockEric Dumazet
TCP V4 sequence numbers are 32bits, and RFC 793 assumed a 250 KHz clock. In order to follow network speed increase, we can use a faster clock, but we should limit this clock so that the delay between two rollovers is greater than MSL (TCP Maximum Segment Lifetime : 2 minutes) Choosing a 64 nsec clock should be OK, since the rollovers occur every 274 seconds.

2007-10-01VT ioctl race fixSamuel Ortiz
When calling the RELDISP VT ioctl, we are reading vt_newvt while the console workqueue could be messing with it (through change_console()). We fix this race by taking the console semaphore before reading vt_newvt.

2007-09-29fix console change race exposed by CFSJan Lübbe
The new behaviour of CFS exposes a race which occurs if a switch is requested when vt_mode.mode is VT_PROCESS. The process with vc->vt_pid is signaled before vc->vt_newvt is set. This causes the switch to fail when triggered by the monitoing process because the target is still -1. [ If the signal sending fails, the subsequent "reset_vc(vc)" will then reset vt_newvt to -1, so this works for that case too. - Linus ] Signed-off-by: Jan Lübbe <jluebbe@lasnet.de> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

If hpet has been initialized before registering hpet driver, the callback function of hpet_resources will return the status code of -EBUSY, which is not defined in the ACPI exception table. So when ACPI checks the status code of callback function, it will report the unknown exception code. So the status code in ACPI is used instead of the generic error code in the ACPI callback function of hpet_resources.

2007-09-19mspec: handle shrinking virtual memory areasCliff Wickman
The shrinking of a virtual memory area that is mmap(2)'d to a memory special file (device drivers/char/mspec.c) can cause a panic. If the mapped size of the vma (vm_area_struct) is very large, mspec allocates a large vma_data structure with vmalloc(). But such a vma can be shrunk by an munmap(2). The current driver uses the current size of each vma to deduce whether its vma_data structure was allocated by kmalloc() or vmalloc(). So if the vma was shrunk it appears to have been allocated by kmalloc(), and mspec attempts to free it with kfree(). This results in a panic. This patch avoids the panic (by preserving the type of the allocation) and also makes mspec work correctly as the vma is split into pieces by the munmap(2)'s. All vma's derived from such a split vma share the same vma_data structure that represents all the pages mapped into this set of vma's. The mpec driver must be made capable of using the right portion of the structure for each member vma. In other words, it must index into the array of page addresses using the portion of the array that represents the current vma. This is enabled by storing the vma group's vm_start in the vma_data structure. The shared vma_data's are not protected by mm->mmap_sem in the fork() case so the reference count is left as atomic_t.

2007-08-31Do not use the ia64 clocksource on non-ia64 architecturesLinus Torvalds
The HPET clocksource in drivers/char/hpet.c was written as generic code for ia64, but it is not yet ready to replace the native HPET clocksource implementations that the i386/x86-64 architectures use. On x86[-64], trying to register this clocksource results in potentially multiple hpet-based clocksources being registered, and if the ia64 one is chosen on x86_64 some users have experienced hangs. Eventually all three architectures may end up using the same code, but that is not the case right now.

2007-08-11fix serial buffer memory leakAlan Cox
Patch c5c34d4862e18ef07c1276d233507f540fb5a532 (tty: flush flip buffer on ldisc input queue flush) introduces a race condition which can lead to memory leaks. The problem can be triggered when tcflush() is called when data are being pushed to the line discipline driver by flush_to_ldisc(). flush_to_ldisc() releases tty->buf.lock when calling the line discipline receive_buf function. At that poing tty_buffer_flush() kicks in and sets both tty->buf.head and tty->buf.tail to NULL. When flush_to_ldisc() finishes, it restores tty->buf.head but doesn't touch tty->buf.tail. This corrups the buffer queue, and the next call to tty_buffer_request_room() will allocate a new buffer and overwrite tty->buf.head. The previous buffer is then lost forever without being released. (Thanks to Laurent for the above text, for finding, disgnosing and reporting the bug) - Use tty->flags bits for the flush status. - Wait for the flag to clear again before returning - Fix the doc error noted - Fix flush of empty queue leaving stale flushpending [akpm@linux-foundation.org: cleanup] Signed-off-by: Alan Cox <alan@redhat.com> Acked-by: Paul Fulghum <paulkf@microgate.com> Cc: Laurent Pinchart <laurentp@cse-semaphore.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

This is only called at init time and only happens if the BIOS screws something up, so the leak is slight and it is probably not worth sending to 2.6.22.x. The driver would not initialize the interface in the case, and I have no reports of this happening. I have booted and run tests on a system with this patch. Note that the original patch was munged by the mailer, here's a new one. If we ever hit the "default:" case in the switch in try_init_dmi(), then we'll leak the storage allocated with kzalloc() and assigned to 'info'.

Remove fs.h from mm.h. For this, 1) Uninline vma_wants_writenotify(). It's pretty huge anyway. 2) Add back fs.h or less bloated headers (err.h) to files that need it. As result, on x86_64 allyesconfig, fs.h dependencies cut down from 3929 files rebuilt down to 3444 (-12.3%).

2007-07-29[WATCHDOG] Fix pcwd_init_module crashWim Van Sebroeck
Fix for the problem detected by Ingo Molnar: enabling CONFIG_PCWATCHDOG=y crashes bzImage bootup. The reason for this can be found in drivers/makefile We first do: obj-y += char/ and later we do: obj-y += base/ block/ misc/ mfd/ net/ media/ So if we put a platform or isa or usb bus driver in char/watchdog (which is called from the Makefile in drivers/char/Makefile) then we didn't have the different device drivers initialized yet (they are in drivers/base and drivers/usb and ...) This fix makes sure that we compile the watchdog drivers after drivers/base, drivers/misc, drivers/pci and drivers/usb. We also do the compile after hwmon because in the future the watchdog temperature support will use the hwmon system. Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
