[PATCH 08/12] PCI: remove initial bios sort of PCI devices on x86
We currently keep 2 lists of PCI devices in the system, one in the driver core, and one all on its own. This second list is sorted at boot time, in BIOS order, to try to remain compatible with older kernels (2.2 and earlier days). There was also a nosort option to turn this sorting off, to remain compatible with even older kernel versions, but that just ends up being what we have been doing from 2.5 days... Unfortunately, the second list of devices is not really ever used to determine the probing order of PCI devices or drivers[1]. That is done using the driver core list instead. This change happened back in the early 2.5 days. Relying on BIOS ording for the binding of drivers to specific device names is problematic for many reasons, and userspace tools like udev exist to properly name devices in a persistant manner if that is needed, no reliance on the BIOS is needed. Matt Domsch and others at Dell noticed this back in 2006, and added a boot option to sort the PCI device lists (both of them) in a breadth-first manner to help remain compatible with the 2.4 order, if needed for any reason. This option is not going away, as some systems rely on them. This patch removes the sorting of the internal PCI device list in BIOS mode, as it's not needed at all anymore, and hasn't for many years. I've also removed the PCI flags for this from some other arches that for some reason defined them, but never used them. This should not change the ordering of any drivers or device probing. [1] The old-style pci_get_device and pci_find_device() still used this sorting order, but there are very few drivers that use these functions, as they are deprecated for use in this manner. If for some reason, a driver rely on the order and uses these functions, the breadth-first boot option will resolve any problem.

[PATCH 11/12] PCI: remove pcibious_fixup_ghosts()
This function was obviously never being used since early 2.5 days as any device that it would try to remove would never really be removed from the system due to the PCI device list being held in the driver core, not the general list of PCI devices. As we have not had a single report of a problem here in 4 years, I think it's safe to remove now.

[ 027/101] staging: zram: Fix handling of incompressible pages
3.6-stable review patch. If anyone has any objections, please let me know. -- From: Nitin Gupta ngu...@vflare.org commit c8f2f0db1d0294aaf37e8a85bea9bbc4aaf5c0fe upstream. Change 130f315a (staging: zram: remove special handle of uncompressed page) introduced a bug in the handling of incompressible pages which resulted in memory allocation failure for such pages. When a page expands on compression, say from 4K to 4K+30, we were trying to do zsmalloc(pool, 4K+30). However, the maximum size which zsmalloc can allocate is PAGE_SIZE (for obvious reasons), so such allocation requests always return failure (0). For a page that has compressed size larger than the original size (this may happen with already compressed or random data), there is no point storing the compressed version as that would take more space and would also require time for decompression when needed again. So, the fix is to store any page, whose compressed size exceeds a threshold (max_zpage_size), as-it-is i.e. without compression. Memory required for storing this uncompressed page can then be requested from zsmalloc which supports PAGE_SIZE sized allocations. Lastly, the fix checks that we do not attempt to decompress the page which we stored in the uncompressed form -- we just memcpy() out such pages.

3.6-stable review patch. If anyone has any objections, please let me know. -- From: Ian Abbott abbo...@mev.co.uk commit 1d1171ffda585c1cab7bd7cf4bd8f8fd5923fb4a upstream. `pc263_detach()` is called by the comedi core to clean up if either `pc263_attach()` or `pc263_attach_pci()` returns an error. It sets `thisboard` to the return value of `comedi_board(dev)` and assumes it is non-null. This is a valid assumption if `pc263_attach()` fails, but not if `pc263_attach_pci()` fails, leading to a possible NULL pointer dereference. Check `thisboard` at the top of `pc263_detach()` and return early if it is `NULL`. This is okay because no other resources need cleaning up in this case.

[ 35/54] ARM: SAMSUNG: Add naming of s3c64xx-spi devices
3.4-stable review patch. If anyone has any objections, please let me know. -- From: Heiko Stuebner he...@sntech.de commit 308b3afb97dc342e9c4f958d8b4c459ae0e22bd7 upstream. Commit a5238e360b71 (spi: s3c64xx: move controller information into driver data) introduced separate device names for the different subtypes of the spi controller but forgot to set these in the relevant machines. To fix this introduce a s3c64xx_spi_setname function and populate all Samsung arches with the correct names. The function resides in a new header, as the s3c64xx-spi.h contains driver platform data and should therefore at some later point move out of the Samsung include dir. Tested on a s3c2416-based machine.

[ 52/54] staging: comedi: amplc_pc236: fix invalid register access during detach
3.4-stable review patch. If anyone has any objections, please let me know. -- From: Ian Abbott abbo...@mev.co.uk commit aaeb61a97b7159ebe30b18a422d04eeabfa8790b upstream. `pc236_detach()` is called by the comedi core if it attempted to attach a device and failed. `pc236_detach()` calls `pc236_intr_disable()` if the comedi device private data pointer (`devpriv`) is non-null. This test is insufficient as `pc236_intr_disable()` accesses hardware registers and the attach routine may have failed before it has saved their I/O base addresses. Fix it by checking `dev-iobase` is non-zero before calling `pc236_intr_disable()` as that means the I/O base addresses have been saved and the hardware registers can be accessed. It also implies the comedi device private data pointer is valid, so there is no need to check it.

The command cancellation code doesn't check whether find_trb_seg() couldn't find the segment that contains the TRB to be canceled. This could cause a NULL pointer deference later in the function when next_trb is called.

[ 07/54] genalloc: stop crashing the system when destroying a pool
3.4-stable review patch. If anyone has any objections, please let me know. -- From: Thadeu Lima de Souza Cascardo casca...@linux.vnet.ibm.com commit eedce141cd2dad8d0cefc5468ef41898949a7031 upstream. The genalloc code uses the bitmap API from include/linux/bitmap.h and lib/bitmap.c, which is based on long values. Both bitmap_set from lib/bitmap.c and bitmap_set_ll, which is the lockless version from genalloc.c, use BITMAP_LAST_WORD_MASK to set the first bits in a long in the bitmap. That one uses (1 bits) - 1, 0b111, if you are setting the first three bits. This means that the API counts from the least significant bits (LSB from now on) to the MSB. The LSB in the first long is bit 0, then. The same works for the lookup functions. The genalloc code uses longs for the bitmap, as it should. In include/linux/genalloc.h, struct gen_pool_chunk has unsigned long bits[0] as its last member. When allocating the struct, genalloc should reserve enough space for the bitmap. This should be a proper number of longs that can fit the amount of bits in the bitmap. However, genalloc allocates an integer number of bytes that fit the amount of bits, but may not be an integer amount of longs. 9 bytes, for example, could be allocated for 70 bits. This is a problem in itself if the Least Significat Bit in a long is in the byte with the largest address, which happens in Big Endian machines. This means genalloc is not allocating the byte in which it will try to set or check for a bit. This may end up in memory corruption, where genalloc will try to set the bits it has not allocated. In fact, genalloc may not set these bits because it may find them already set, because they were not zeroed since they were not allocated. And that's what causes a BUG when gen_pool_destroy is called and check for any set bits. What really happens is that genalloc uses kmalloc_node with __GFP_ZERO on gen_pool_add_virt. With SLAB and SLUB, this means the whole slab will be cleared, not only the requested bytes. Since struct gen_pool_chunk has a size that is a multiple of 8, and slab sizes are multiples of 8, we get lucky and allocate and clear the right amount of bytes. Hower, this is not the case with SLOB or with older code that did memset after allocating instead of using __GFP_ZERO. So, a simple module as this (running 3.6.0), will cause a crash when rmmod'ed.

[ 16/54] sysfs: sysfs_pathname/sysfs_add_one: Use strlcat() instead of strcat()
3.4-stable review patch. If anyone has any objections, please let me know. -- From: Geert Uytterhoeven ge...@linux-m68k.org commit 66081a72517a131430dcf986775f3268aafcb546 upstream. The warning check for duplicate sysfs entries can cause a buffer overflow when printing the warning, as strcat() doesn't check buffer sizes. Use strlcat() instead. Since strlcat() doesn't return a pointer to the passed buffer, unlike strcat(), I had to convert the nested concatenation in sysfs_add_one() to an admittedly more obscure comma operator construct, to avoid emitting code for the concatenation if CONFIG_BUG is disabled.

[ 11/54] SUNRPC: Get rid of the xs_error_report socket callback
3.4-stable review patch. If anyone has any objections, please let me know. -- From: Trond Myklebust trond.mykleb...@netapp.com commit f878b657ce8e7d3673afe48110ec208a29e38c4a upstream. Chris Perl reports that we're seeing races between the wakeup call in xs_error_report and the connect attempts. Basically, Chris has shown that in certain circumstances, the call to xs_error_report causes the rpc_task that is responsible for reconnecting to wake up early, thus triggering a disconnect and retry. Since the sk-sk_error_report() calls in the socket layer are always followed by a tcp_done() in the cases where we care about waking up the rpc_tasks, just let the state_change callbacks take responsibility for those wake ups.

[ 08/54] ARM: 7559/1: smp: switch away from the idmap before updating init_mm.mm_count
3.4-stable review patch. If anyone has any objections, please let me know. -- From: Will Deacon will.dea...@arm.com commit 5f40b909728ad784eb43aa309d3c4e9bdf050781 upstream. When booting a secondary CPU, the primary CPU hands two sets of page tables via the secondary_data struct: (1) swapper_pg_dir: a normal, cacheable, shared (if SMP) mapping of the kernel image (i.e. the tables used by init_mm). (2) idmap_pgd: an uncached mapping of the .idmap.text ELF section. The idmap is generally used when enabling and disabling the MMU, which includes early CPU boot. In this case, the secondary CPU switches to swapper as soon as it enters C code: struct mm_struct *mm = init_mm; unsigned int cpu = smp_processor_id(); /* * All kernel threads share the same mm context; grab a * reference and switch to it. */ atomic_inc(mm-mm_count); current-active_mm = mm; cpumask_set_cpu(cpu, mm_cpumask(mm)); cpu_switch_mm(mm-pgd, mm); This causes a problem on ARMv7, where the identity mapping is treated as strongly-ordered leading to architecturally UNPREDICTABLE behaviour of exclusive accesses, such as those used by atomic_inc. This patch re-orders the secondary_start_kernel function so that we switch to swapper before performing any exclusive accesses.

[ 10/54] mm: fix XFS oops due to dirty pages without buffers on s390
3.4-stable review patch. If anyone has any objections, please let me know. -- From: Jan Kara j...@suse.cz commit ef5d437f71afdf4afdbab99213add99f4b1318fd upstream. On s390 any write to a page (even from kernel itself) sets architecture specific page dirty bit. Thus when a page is written to via buffered write, HW dirty bit gets set and when we later map and unmap the page, page_remove_rmap() finds the dirty bit and calls set_page_dirty(). Dirtying of a page which shouldn't be dirty can cause all sorts of problems to filesystems. The bug we observed in practice is that buffers from the page get freed, so when the page gets later marked as dirty and writeback writes it, XFS crashes due to an assertion BUG_ON(!PagePrivate(page)) in page_buffers() called from xfs_count_page_state(). Similar problem can also happen when zero_user_segment() call from xfs_vm_writepage() (or block_write_full_page() for that matter) set the hardware dirty bit during writeback, later buffers get freed, and then page unmapped. Fix the issue by ignoring s390 HW dirty bit for page cache pages of mappings with mapping_cap_account_dirty(). This is safe because for such mappings when a page gets marked as writeable in PTE it is also marked dirty in do_wp_page() or do_page_fault(). When the dirty bit is cleared by clear_page_dirty_for_io(), the page gets writeprotected in page_mkclean(). So pagecache page is writeable if and only if it is dirty. Thanks to Hugh Dickins for pointing out mapping has to have mapping_cap_account_dirty() for things to work and proposing a cleaned up variant of the patch. The patch has survived about two hours of running fsx-linux on tmpfs while heavily swapping and several days of running on out build machines where the original problem was triggered.

[ 04/54] gen_init_cpio: avoid stack overflow when expanding
3.4-stable review patch. If anyone has any objections, please let me know. -- From: Kees Cook keesc...@chromium.org commit 20f1de659b77364d55d4e7fad2ef657e7730323f upstream. Fix possible overflow of the buffer used for expanding environment variables when building file list. In the extremely unlikely case of an attacker having control over the environment variables visible to gen_init_cpio, control over the contents of the file gen_init_cpio parses, and gen_init_cpio was built without compiler hardening, the attacker can gain arbitrary execution control via a stack buffer overflow. $ cat usr/crash.list file foo ${BIG}${BIG}${BIG}${BIG}${BIG}${BIG} 0755 0 0 $ BIG=$(perl -e 'print A x 4096;') ./usr/gen_init_cpio usr/crash.list *** buffer overflow detected ***: ./usr/gen_init_cpio terminated This also replaces the space-indenting with tabs.

[ 060/101] USB: quatech2: fix port-data memory leaks
3.6-stable review patch. If anyone has any objections, please let me know. -- From: Johan Hovold jhov...@gmail.com commit 40d04738491d7ac1aa708ba434ff3480ec9e1b96 upstream. Fix port-data memory leak by moving port data allocation and deallocation to port_probe and port_remove. Since commit 0998d0631001288 (device-core: Ensure drvdata = NULL when no driver is bound) the port private data is no longer freed at release as it is no longer accessible. Note that this also fixes memory leaks in the error path of attach where the write urbs were not freed on errors. Make sure all interface-data deallocation is done in release by moving the read urb deallocation from disconnect. Note that the write urb is killed during close so that the call in disconnect was superfluous. Compile-only tested.

[ 075/101] ARM: at91: at91sam9g10: fix SOC type detection
3.6-stable review patch. If anyone has any objections, please let me know. -- From: Ivan Shugov ivan.shu...@gmail.com commit 3d9a0183dd3423353e9e363bcc261c1220d05f9f upstream. Newer at91sam9g10 SoC revision can't be detected, so the kernel can't boot with this kind of kernel panic: AT91: Impossible to detect the SOC type CPU: ARM926EJ-S [41069265] revision 5 (ARMv5TEJ), cr=00053177 CPU: VIVT data cache, VIVT instruction cache Machine: Atmel AT91SAM9G10-EK Ignoring tag cmdline (using the default kernel command line) bootconsole [earlycon0] enabled Memory policy: ECC disabled, Data cache writeback Kernel panic - not syncing: AT91: Impossible to detect the SOC type [c00133d4] (unwind_backtrace+0x0/0xe0) from [c02366dc] (panic+0x78/0x1cc) [c02366dc] (panic+0x78/0x1cc) from [c02fa35c] (at91_map_io+0x90/0xc8) [c02fa35c] (at91_map_io+0x90/0xc8) from [c02f9860] (paging_init+0x564/0x6d0) [c02f9860] (paging_init+0x564/0x6d0) from [c02f7914] (setup_arch+0x464/0x704) [c02f7914] (setup_arch+0x464/0x704) from [c02f44f8] (start_kernel+0x6c/0x2d4) [c02f44f8] (start_kernel+0x6c/0x2d4) from [20008040] (0x20008040) The reason for this is that the Debug Unit Chip ID Register has changed between Engineering Sample and definitive revision of the SoC. Changing the check of cidr to socid will address the problem. We do not integrate this check to the list just above because we also have to make sure that the extended id is disregarded.
