From: Harald Welte <laforge@gnumonks.org> [disclaimer: This was posted on the linuxppc list before, BenH asked me=20 to re-post it to lkml] The prism54 (http://prism54.org) driver for my cardbus adapter works with 2.4.x, but not 2.6.x on a Titanium G4 Powerbook IV. On 2.6.x the error message was PCI:0001:02:00.0 Resource 0 [00000000-00001fff] is unassigned After investigating differences in the PCI code of 2.4.x and 2.6.x, i noticed that 2.4.x/arc/ppc/kernel/pci.c:pcibios_update_resource() contained a couple of lines that unset the IORESOURCE_UNSET bitflag. In 2.6.x, this is handled by the generic PCI core in drivers/pci/setup-res.c:pci_update_resource() code. However, the code is missing the 'res->flags &=3D ~IORESOURCE_UNSET' part. The below fix re-adds that section from 2.4.x.=20 I'm not sure wether this belongs into the arch-independent PCI api. Anyway, on PPC it seems to be needed for certain cardbus devices. Any comments welcome.

qlogic's 16k maximum I/O size bites again. Neil says: The problems we fixed were all to do with normal IO. This one is resync IO. The problem here is that raid1 always does resync in RESYNC_BLOCK_SIZE (=64k) IOs and if the device doesn't cope - tough. The simple fix is to #define RESYNC_BLOCK_SIZE to PAGE_SIZE in md/raid1.c The better fix is to rewrite the raid1 resync code to use bio_add_page. This means we have to build the read request and the write requests at the same time, and then when a bio_add_page fails, we back-out the last page from the bios that have one too many, and then do the read followed by the writes. I have some code the nearly does this, but I haven't got it actually working yet and I am on leave until mid January. I would recommend doing fs/drivers/md/raid1.c: -#define RESYNC_BLOCK_SIZE (64*1024) +#define RESYNC_BLOCK_SIZE PAGE_SIZE for now.

From: Jon Burgess <mplayer@jburgess.uklinux.net> The iso9660 filesystem code checks that the "sbsector" option is positioned within the first 660Mb of the disk. Today the iso9660 filesystem is used on DVD's which are much bigger than 660Mb and this check prevents the sbsector option being used to specify the location of the superblock of multisession DVD's. With this check removed I can mount the second session on a DVD-R by specifying the sbsector, even though the firmware on that drive returns bogus data for the TOC. If an invalid large sector number is entered then a "request beyond end of device" error is reported elsewhere in the block code, but appears to do no damage.

From: "Seth, Rohit" <rohit.seth@intel.com> We recently covered a bug in mm/mmap.c on IA-64. While unmapping a address space, unmap_region calls free_pgtables to possibly free the pages that are used for page tables. Currently no distinction is made between freeing a region that is mapped by normal pages vs the pages that are mapped by hugepages. Architecture specific code needs to handle cases where PTEs corresponding to a region that is mapped by hugepages is properly getting unmapped. Attached please find a patch that makes the required changes in generic part of kernel. We will need to send a separate IA-64 patch to use this new semantics. Currently, so not to disturb the PPC (as that is the only arch that had ARCH_HAS_HUGEPAGE_ONLY_RANGE defined) we are mapping back the definition of new function hugetlb_free_pgtables to free_pgtables.

From: Mark Haverkamp <markh@osdl.org> This fixes a problem similar to the patch I submitted on 11/20 http://marc.theaimsgroup.com/?l=linux-kernel&m=106936439707962&w=2 In this case, though, the result is an: "Incorrect number of segments after building list" message. The macro __BVEC_START assumes a bi_idx of zero when the dm code can submit a bio with a non-zero bi_idx. The code has been tested on an 8 way / 8gb OSDL STP machine with a 197G lvm volume running dbt2 test.

From: Michael Hunold <hunold@convergence.de> the Linux-on-a-CD system Knoppix has nearly all framebuffer drivers for 2.4.23 compiled in. Additionally, it surpresses most kernel messages by lowering the kernel log level. Two framebuffer drivers (clgenfb.c and hgafb.c), however, use KERN_ERR to say that their particular card has *not* been found which is very annoying. Especially the clgenfb.c driver simply says on bootup: > Couldn't find PCI device which can really confuse newbie users. I've already send a patch that fixes this for 2.4 -- Marcelo and Geert Uytterhoeven have already ack'ed it. The same change should be done for 2.6, too IMHO. The appended patch replaces two KERN_ERR with KERN_INFO and additionally makes the cirrusfb.c message more descriptive.

From: IWAMOTO Toshihiro <iwamoto@valinux.co.jp> I found linux-2.6.0-test11 leaks memory when execve fails. I've also checked the bitkeeper tree and the problem seems to be unchanged. The attached patch is a partial backout of bitkeeper rev. 1.87 of fs/exec.c. I guess the original change was a simple mistake. (free_arg_pages() is a NOP when CONFIG_MMU is defined).

From: "H. Peter Anvin" <hpa@zytor.com> This patch fixes the "non-terminating inflate" problem that Russell King complained about on LKML earlier today. I chose to use "goto" much like zlib does, in order to not require setjmp/longjmp inside the kernel. It's a bit ugly, but it also lets each function chose how it needs to be terminated on error, which is a good thing.

From: OGAWA Hirofumi <hirofumi@mail.parknet.co.jp> Michal Rokos <m.rokos@sh.cvut.cz> The problem is: even if vfat_striptail_len() counts len of name without trailing dots and sets len to the correct value, utf8_mbstowcs() doesn't care about len and takes whole name. So dirs and files with dots can be created on vfat fs.

From: David Mosberger <davidm@napali.hpl.hp.com> This patch makes /proc/PID/maps report the range from FIXADDR_USER_START to FIXADDR_USER_END as a final pseudo-vma. This is consistent with the notion that reading /proc/PID/maps tells you about every page containing data that the process can in fact access, and with things such as ptrace allowing access to this memory. Without this, userland tools that want to look at all of a process's accessible pages need special-case knowledge about things such as the vsyscall DSO page. With this change, existing code that iterates over the /proc/PID/maps lines will cover those pages like any other. For example, this lets gdb's "gcore" command synthesize a core file from a live process that contains the vsyscall DSO page as a real core dump would, using its existing generic iterator code and no new special cases.

From: Chris Bajumpaa <cbajumpa@or8.net> This patch fixes a problem with the TSC failing on via686a/KX133 motherboards either reverting to using the pit or deadlocking the machine alltogether under heavy load. (Specifically Abit KA7/KA7-100). Message from the log: Dec 18 18:20:37 grinder kernel: Losing too many ticks! Dec 18 18:20:37 grinder kernel: TSC cannot be used as a timesource. (Are you running with SpeedStep?) Dec 18 18:20:37 grinder kernel: Falling back to a sane timesource. The snippet of code that was missing from timer_tsc.c comes from timer_pit.c.

From: Matthew Dobson <colpatch@us.ibm.com> The code to parse the EBDA (Extended BIOS Data Area) for Summit boxen is broken because it does not handle Lookout boxen (external boxes full of additional PCI slots). This patch cleans up some ugliness in arch/i386/kernel/summit.c as well as fixing the code to handle Lookout boxen and various other configurations of PCI buses. Without this, Summit PCI bus to node mappings are totally hosed with Lookout boxen attatched. This patch depends upon the GENERICARCH fix.

From: Matthew Dobson <colpatch@us.ibm.com> Trying to build a kernel with both CONFIG_X86_GENERICARCH and CONFIG_NUMA on results in a compile error. This patch fixes that build problem by adding a config option for NUMA on Summit which is used to correctly conditionally compile arch/i386/kernel/summit.c and properly ifdef the function calls used in generic code. Please apply.

From: Stephen Smalley <sds@epoch.ncsc.mil> This patch against 2.6.0 adds a control to the SELinux module over the inheritance of signal-related state upon security context transitions in order to protect the new security context. If the permission is not granted by the policy for a given pair of contexts, then transitions between them will clear itimers, flush all pending signals, forcibly flush signal handlers, and unblock all signals. Roland McGrath provided input and feedback on the patch. Please apply, or let James Morris and me know if you'd like this to be resubmitted later. Thanks.

From: Stephen Smalley <sds@epoch.ncsc.mil> This patch removes the use of nameidata by selinux_inode_permission, as this appears to be unsafe in certain cases (e.g. path_walk call from rpc_lookup_parent), leading to an Oops if d_path is subsequently called by avc_audit on the (mnt,dentry) pair to generate a pathname for an audit message. The change does not affect the ability of SELinux to perform its permission check (which only requires the inode), only the set of information that is available for audit messages. We'll investigate better approaches for the SELinux audit generation in the future.
