* fat: Fix and cleanup timestamp conversionOGAWA Hirofumi2008-11-066-72/+130
| | | | | | | | | | | | | This cleans date_dos2unix()/fat_date_unix2dos() up. New code should be much more readable. And this fixes those old functions. Those doesn't handle 2100 correctly. 2100 isn't leap year, but old one handles it as leap year. Also, with this, centi sec is handled and is fixed.

* atmel_serial: keep clock off when it's not neededDavid Brownell2008-11-061-3/+14
| | | | | | | | | | | | | | | | | | | | | | The atmel_serial driver is mismanaging its clock by leaving it on at all times ... the whole point of clock management is to leave it off unless it's actively needed, which conserves power!! Although the kernel doesn't actually hang without my fix, it does discard quite a lot of early console output. The result still looks correct: usart users= 1 on 35000000 Hz, for atmel_usart.0 usart users= 0 off 35000000 Hz, for atmel_usart.2 when using ttyS0 as serial console.

* fbdev: fix fb_compat_ioctl() deadlocksGeert Uytterhoeven2008-11-061-24/+39
| | | | | | | | | | | | | | | | | | | | | | | | | commit 3e680aae4e53ab54cdbb0c29257dae0cbb158e1c ("fb: convert lock/unlock_kernel() into local fb mutex") introduced several deadlocks in the fb_compat_ioctl() path, as mutex_lock() doesn't allow recursion, unlike lock_kernel(). This broke frame buffer applications on 64-bit systems with a 32-bit userland. commit 120a37470c2831fea49fdebaceb5a7039f700ce6 ("framebuffer compat_ioctl deadlock") fixed one of the deadlocks. This patch fixes the remaining deadlocks: - Revert commit 120a37470c2831fea49fdebaceb5a7039f700ce6, - Extract the core logic of fb_ioctl() into a new function do_fb_ioctl(), - Change all callsites of fb_ioctl() where info->lock is already held to call do_fb_ioctl() instead, - Add sparse annotations to all routines that take info->lock.

* memory hotplug: fix page_zone() calculation in test_pages_isolated()Gerald Schaefer2008-11-061-2/+3
| | | | | | | | | | | | | | | | | My last bugfix here (adding zone->lock) introduced a new problem: Using page_zone(pfn_to_page(pfn)) to get the zone after the for() loop is wrong. pfn will then be >= end_pfn, which may be in a different zone or not present at all. This may lead to an addressing exception in page_zone() or spin_lock_irqsave(). Now I use __first_valid_page() again after the loop to find a valid page for page_zone().

* ext3: wait on all pending commits in ext3_sync_fsArthur Jones2008-11-061-6/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In ext3_sync_fs, we only wait for a commit to finish if we started it, but there may be one already in progress which will not be synced. In the case of a data=ordered umount with pending long symlinks which are delayed due to a long list of other I/O on the backing block device, this causes the buffer associated with the long symlinks to not be moved to the inode dirty list in the second phase of fsync_super. Then, before they can be dirtied again, kjournald exits, seeing the UMOUNT flag and the dirty pages are never written to the backing block device, causing long symlink corruption and exposing new or previously freed block data to userspace. This can be reproduced with a script created by Eric Sandeen <sandeen@redhat.com>: #!/bin/bash umount /mnt/test2 mount /dev/sdb4 /mnt/test2 rm -f /mnt/test2/* dd if=/dev/zero of=/mnt/test2/bigfile bs=1M count=512 touch /mnt/test2/thisisveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryverylongfilename ln -s /mnt/test2/thisisveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryverylongfilename /mnt/test2/link umount /mnt/test2 mount /dev/sdb4 /mnt/test2 ls /mnt/test2/ umount /mnt/test2 To ensure all commits are synced, we flush all journal commits now when sync_fs'ing ext3.

* hugetlb: pull gigantic page initialisation out of the default pathAndy Whitcroft2008-11-063-8/+33
| | | | | | | | | | | | | | | | | | As we can determine exactly when a gigantic page is in use we can optimise the common regular page cases by pulling out gigantic page initialisation into its own function. As gigantic pages are never released to buddy we do not need a destructor. This effectivly reverts the previous change to the main buddy allocator. It also adds a paranoid check to ensure we never release gigantic pages from hugetlbfs to the main buddy.

* hugetlbfs: handle pages higher order than MAX_ORDERAndy Whitcroft2008-11-062-1/+64
| | | | | | | | | | | | | | | | | | | | | | | | | | When working with hugepages, hugetlbfs assumes that those hugepages are smaller than MAX_ORDER. Specifically it assumes that the mem_map is contigious and uses that to optimise access to the elements of the mem_map that represent the hugepage. Gigantic pages (such as 16GB pages on powerpc) by definition are of greater order than MAX_ORDER (larger than MAX_ORDER_NR_PAGES in size). This means that we can no longer make use of the buddy alloctor guarentees for the contiguity of the mem_map, which ensures that the mem_map is at least contigious for maximmally aligned areas of MAX_ORDER_NR_PAGES pages. This patch adds new mem_map accessors and iterator helpers which handle any discontiguity at MAX_ORDER_NR_PAGES boundaries. It then uses these to implement gigantic page versions of copy_huge_page and clear_huge_page, and to allow follow_hugetlb_page handle gigantic pages.

| | | | | | | | | | | | | | | | | __scm_destroy() walks the list of file descriptors in the scm_fp_list pointed to by the scm_cookie argument. Those, in turn, can close sockets and invoke __scm_destroy() again. There is nothing which limits how deeply this can occur. The idea for how to fix this is from Linus. Basically, we do all of the fput()s at the top level by collecting all of the scm_fp_list objects hit by an fput(). Inside of the initial __scm_destroy() we keep running the list until it is empty.

| | | | | | | | | | | | | | | | | | | | The current code read nothing but zeros on big-endian (wrong part of the 32bits). This caused poor performance on big-endian machines. Though this issue did not cause the system to crash, the performance is significantly better with the fix so I view it as critical bug fix.

| * mv643xx_eth: fix SMI bus access timeoutsLennert Buytenhek2008-11-031-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The mv643xx_eth mii bus implementation uses wait_event_timeout() to wait for SMI completion interrupts. If wait_event_timeout() would return zero, mv643xx_eth would conclude that the SMI access timed out, but this is not necessarily true -- wait_event_timeout() can also return zero in the case where the SMI completion interrupt did happen in time but where it took longer than the requested timeout for the process performing the SMI access to be scheduled again. This would lead to occasional SMI access timeouts when the system would be under heavy load. The fix is to ignore the return value of wait_event_timeout(), and to re-check the SMI done bit after wait_event_timeout() returns to determine whether or not the SMI access timed out.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While adding support for MIGRATE/KMADDRESS in strongSwan (as specified in draft-ebalard-mext-pfkey-enhanced-migrate-00), Andreas Steffen noticed that XFRMA_KMADDRESS attribute passed to userland contains the local address twice (remote provides local address instead of remote one). This bug in copy_to_user_kmaddress() affects only key managers that use native XFRM interface (key managers that use PF_KEY are not affected). For the record, the bug was in the initial changeset I posted which added support for KMADDRESS (13c1d18931ebb5cf407cb348ef2cd6284d68902d 'xfrm: MIGRATE enhancements (draft-ebalard-mext-pfkey-enhanced-migrate)').

Endpoint A Endpoint B UDP Echo request -----------> (IPv4, Dst port=7) <---------- UDP Echo Reply (IPv4, Src port=7) This bug is come from this patch cb75994ec311b2cd50e5205efdcc0696abd6675d. It do counter UDP[6]_MIB_INDATAGRAMS until udp[v6]_recvmsg. Because xinetd used IPv6 socket to receive UDP messages, thus, when received UDP packet, the UDP6_MIB_INDATAGRAMS will be increased in function udpv6_recvmsg() even if the packet is a IPv4 UDP packet.
