* [PATCH] Fix signal sending in usbdevio on async URB completionHarald Welte2005-10-10
| | | | | | | | | | | | | | | | | | | | | | | | | | If a process issues an URB from userspace and (starts to) terminate before the URB comes back, we run into the issue described above. This is because the urb saves a pointer to "current" when it is posted to the device, but there's no guarantee that this pointer is still valid afterwards. In fact, there are three separate issues: 1) the pointer to "current" can become invalid, since the task could be completely gone when the URB completion comes back from the device. 2) Even if the saved task pointer is still pointing to a valid task_struct, task_struct->sighand could have gone meanwhile. 3) Even if the process is perfectly fine, permissions may have changed, and we can no longer send it a signal. So what we do instead, is to save the PID and uid's of the process, and introduce a new kill_proc_info_as_uid() function.

* | | [PATCH] i386: fix stack alignment for signal handlersMarkus F.X.J. Oberhumer2005-10-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes the setup of the alignment of the signal frame, so that all signal handlers are run with a properly aligned stack frame. The current code "over-aligns" the stack pointer so that the stack frame is effectively always mis-aligned by 4 bytes. But what we really want is that on function entry ((sp + 4) & 15) == 0, which matches what would happen if the stack were aligned before a "call" instruction. Signed-off-by: Markus F.X.J.

* | | [PATCH] ide: Workaround PM problemBenjamin Herrenschmidt2005-10-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The logic in ide_do_request() doesn't guarantee that both drives will be serviced after a call. It may "forget" to service one in some circumstances, including when one of the drive is suspended (it will eventually fail to service the slave when the master is suspended for example). This prevents the wakeup requests that gets queued on wakeup from sleep from beeing serviced in some cases when 2 drives are sharing an IDE bus. The problem is deep enough in the way this code works (and there are probably a few other problematic but rare corner cases) and fixing it would require some major rethinking of the way IDE decides which channel to service. This is not 2.6.14 material. However, in the meantime, Bart has accepted this simple workaround that will fix the crash on wakeup from sleep since this specific corner case is actually hitting users to get into 2.6.14.

* | [PATCH] x86_64: Set up safe page tables during resumeRafael J. Wysocki2005-10-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The following patch makes swsusp avoid the possible temporary corruption of page translation tables during resume on x86-64. This is achieved by creating a copy of the relevant page tables that will not be modified by swsusp and can be safely used by it on resume. The problem is that during resume on x86-64 swsusp may temporarily corrupt the page tables used for the direct mapping of RAM. If that happens, a page fault occurs and cannot be handled properly, which leads to the solid hang of the affected system. This leads to the loss of the system's state from before suspend and may result in the loss of data or the corruption of filesystems, so it is a serious issue. Also, it appears to happen quite often (for me, as often as 50% of the time). The problem is related to the fact that (at least) one of the PMD entries used in the direct memory mapping (starting at PAGE_OFFSET) points to a page table the physical address of which is much greater than the physical address of the PMD entry itself. Moreover, unfortunately, the physical address of the page table before suspend (i.e. the one stored in the suspend image) happens to be different to the physical address of the corresponding page table used during resume (i.e. the one that is valid right before swsusp_arch_resume() in arch/x86_64/kernel/suspend_asm.S is executed). Thus while the image is restored, the "offending" PMD entry gets overwritten, so it does not point to the right physical address any more (i.e. there's no page table at the address pointed to by it, because it points to the address the page table has been at during suspend). Consequently, if the PMD entry is used later on, and it _is_ used in the process of copying the image pages, a page fault occurs, but it cannot be handled in the normal way and the system hangs. In principle we can call create_resume_mapping() from swsusp_arch_resume() (ie. from suspend_asm.S), but then the memory allocations in create_resume_mapping(), resume_pud_mapping(), and resume_pmd_mapping() must be made carefully so that we use _only_ NosaveFree pages in them (the other pages are overwritten by the loop in swsusp_arch_resume()). Additionally, we are in atomic context at that time, so we cannot use GFP_KERNEL. Moreover, if one of the allocations fails, we should free all of the allocated pages, so we need to trace them somehow. All of this is done in the appended patch, except that the functions populating the page tables are located in arch/x86_64/kernel/suspend.c rather than in init.c. It may be done in a more elegan way in the future, with the help of some swsusp patches that are in the works now. [AK: move some externs into headers, renamed a function] Signed-off-by: Rafael J.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 44456d37b59d8e541936ed26d8b6e08d27e88ac1, between 2.6.13-rc3 and -rc4, was a "nice cleanup" which broke something. Revert the offending part. It broke because: a) because this part doesn't fall under the description b) the author didn't know what he was doing here c) the author didn't try to compile the existing code and see that it worked perfectly. d) the author didn't ask us what was happening e) you didn't either, and somebody there should have learned that UML is a bit different. In fact, UML is special in linking to host libc and using its includes. In particular, since host includes always define both __BIG_ENDIAN and __LITTLE_ENDIAN, ntohll() macros started thinking to be in a big-endian world; and on-disk compatibility was broken. Many thanks go to Nix for reporting the problem and correctly diagnosing an endianness problem. Btw, this patch restores the previous code, which worked; but the definitions would be uncorrect if used in kernelspace files. Next patch addresses that.
