2007-01-26[PATCH] knfsd: replace some warning ins nfsfh.h with BUG_ON or WARN_ONNeilBrown
A couple of the warnings will be followed by an Oops if they ever fire, so may as well be BUG_ON. Another isn't obviously fatal but has never been known to fire, so make it a WARN_ON.

2007-01-26[PATCH] knfsd: fix an NFSD bug with full sized, non-page-aligned readsNeilBrown
NFSd assumes that largest number of pages that will be needed for a request+response is 2+N where N pages is the size of the largest permitted read/write request. The '2' are 1 for the non-data part of the request, and 1 for the non-data part of the reply. However, when a read request is not page-aligned, and we choose to use ->sendfile to send it directly from the page cache, we may need N+1 pages to hold the whole reply. This can overflow and array and cause an Oops. This patch increases size of the array for holding pages by one and makes sure that entry is NULL when it is not in use.

2007-01-26[PATCH] i386 vDSO: use VM_ALWAYSDUMPRoland McGrath
This patch fixes core dumps to include the vDSO vma, which is left out now. It removes the special-case core writing macros, which were not doing the right thing for the vDSO vma anyway. Instead, it uses VM_ALWAYSDUMP in the vma; there is no need for the fixmap page to be installed. It handles the CONFIG_COMPAT_VDSO case by making elf_core_dump use the fake vma from get_gate_vma after real vmas in the same way the /proc/PID/maps code does. This changes core dumps so they no longer include the non-PT_LOAD phdrs from the vDSO. I made the change to add them in the first place, but in turned out that nothing ever wanted them there since the advent of NT_AUXV. It's cleaner to leave them out, and just let the phdrs inside the vDSO image speak for themselves.

2007-01-26[PATCH] Fix CONFIG_COMPAT_VDSORoland McGrath
I wouldn't mind if CONFIG_COMPAT_VDSO went away entirely. But if it's there, it should work properly. Currently it's quite haphazard: both real vma and fixmap are mapped, both are put in the two different AT_* slots, sysenter returns to the vma address rather than the fixmap address, and core dumps yet are another story. This patch makes CONFIG_COMPAT_VDSO disable the real vma and use the fixmap area consistently. This makes it actually compatible with what the old vdso implementation did.

2007-01-24[MIPS] Fix wrong checksum calculation on 64-bit MIPSAtsushi Nemoto
The commit 8e3d8433d8c22ca6c42cba4a67d300c39aae7822 ([NET]: MIPS checksum annotations and cleanups) broke 64-bit MIPS. The problem is the commit replaces some unsigned long with __be32. On 64bit MIPS, a __be32 (i.e. unsigned int) value is represented as a sign-extented 32-bit value in a 64-bit argument register. So the address 192.168.0.1 (0xc0a80001) is passed as 0xffffffffc0a80001 to csum_tcpudp_nofold() but the asm code in the function expects 0x00000000c0a80001, therefore it returns a wrong checksum. Explicit cast to unsigned long is needed to drop high 32bit. Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2007-01-23[NETFILTER]: Fix iptables ABI breakage on (at least) CRISPatrick McHardy
With the introduction of x_tables we accidentally broke compatibility by defining IPT_TABLE_MAXNAMELEN to XT_FUNCTION_MAXNAMELEN instead of XT_TABLE_MAXNAMELEN, which is two bytes larger. On most architectures it doesn't really matter since we don't have any tables with names that long in the kernel and the structure layout didn't change because of alignment requirements of following members. On CRIS however (and other architectures that don't align data) this changed the structure layout and thus broke compatibility with old iptables binaries. Changing it back will break compatibility with binaries compiled against recent kernels again, but since the breakage has only been there for three releases this seems like the better choice.

2007-01-23[MIPS] SMTC: Instant IPI replay.Ralf Baechle
SMTC pseudo-interrupts between TCs are deferred and queued if the target TC is interrupt-inhibited (IXMT). In the first SMTC prototypes, these queued IPIs were serviced on return to user mode, or on entry into the kernel idle loop. The INSTANT_REPLAY option dispatches them as part of local_irq_restore() processing, which adds runtime overhead (hence the option to turn it off), but ensures that IPIs are handled promptly even under heavy I/O interrupt load.

2007-01-23[PATCH] resierfs: avoid tail packing if an inode was ever mmappedVladimir Saveliev
This patch fixes a confusion reiserfs has for a long time. On release file operation reiserfs used to try to pack file data stored in last incomplete page of some files into metadata blocks. After packing the page got cleared with clear_page_dirty. It did not take into account that the page may be mmaped into other process's address space. Recent replacement for clear_page_dirty cancel_dirty_page found the confusion with sanity check that page has to be not mapped. The patch fixes the confusion by making reiserfs avoid tail packing if an inode was ever mmapped. reiserfs_mmap and reiserfs_file_release are serialized with mutex in reiserfs specific inode. reiserfs_mmap locks the mutex and sets a bit in reiserfs specific inode flags. reiserfs_file_release checks the bit having the mutex locked. If bit is set - tail packing is avoided. This eliminates a possibility that mmapped page gets cancel_page_dirty-ed.

2007-01-22[PATCH] x86: fix PDA variables to work during bootJames Bottomley
The current PDA code, which went in in post 2.6.19 has a flaw in that it doesn't correctly cycle the GDT and %GS segment through the boot PDA, the CPU PDA and finally the per-cpu PDA. The bug generally doesn't show up if the boot CPU id is zero, but everything falls apart for a non zero boot CPU id. The basically kills voyager which is perfectly capable of doing non zero CPU id boots, so voyager currently won't boot without this. The fix is to be careful and actually do the GDT setups correctly.

2007-01-22[POWERPC] atomic_dec_if_positive sign extension fixRobert Jennings
On 64-bit machines, if an atomic counter is explicitly set to a negative value, the atomic_dec_if_positive function will decrement and store the next smallest value in the atomic counter, contrary to its intended operation. The comparison to determine if the decrement will make the result negative was done by the "addic." instruction, which operates on a 64-bit value, namely the zero-extended word loaded from the atomic variable. This patch uses an explicit word compare (cmpwi) and changes the addic. to an addi (also changing "=&r" to "=&b" so that r0 isn't used, and addi doesn't become li). This also fixes a bug for both 32-bit and 64-bit in that previously 0x80000000 was considered positive, since the result after decrementing is positive. Now it is considered negative. Also, I clarify the return value in the comments just to make it clear that the value returned is always the decremented value, even if that value is not stored back to the atomic counter.

libata didn't used to init qc->dma_dir to any specific value on qc initialization and command translation path didn't set qc->dma_dir if the command doesn't need data transfer. This made non-data commands to have random qc->dma_dir. This usually doesn't cause problem because LLDs usually check qc->protocol first and look at qc->dma_dir iff the command needs data transfer but this doesn't hold for all LLDs. It might be worthwhile to rename qc->dma_dir to qc->data_dir as we use the field to tag data direction for both PIO and DMA protocols. This problem has been spotted by James Bottomley.

In order to fix this, NFS has hooked the releasepage() method and tries to write the page out between the call to unmap_mapping_range() and the call to remove_mapping(). This, however leads to deadlocks in the page reclaim code, where the page may be locked without holding a reference to the inode or dentry. Fix is to add a new address_space_operation, launder_page(), which will attempt to write out a dirty page without releasing the page lock.

2007-01-11[PATCH] Fix sparsemem on CellDave Hansen
Fix an oops experienced on the Cell architecture when init-time functions, early_*(), are called at runtime. It alters the call paths to make sure that the callers explicitly say whether the call is being made on behalf of a hotplug even, or happening at boot-time. It has been compile tested on ppc64, ia64, s390, i386 and x86_64.

+m is really correct for a RMW instruction, but some older gccs error out. I finally gave in and ifdefed it. This fixes compilation errors with some compiler version. Signed-off-by: Andi Kleen <ak@suse.de>
