| * gen_init_cpio: Avoid race between call to stat() and call to open()Jesper Juhl2010-12-29
| | | | | | | | | | | | | | | | | | | | | | | | | | In usr/gen_init_cpio.c::cpio_mkfile() a call to stat() is made based on pathname, subsequently the file is open()'ed and then the value of the initial stat() call is used to allocate a buffer. This is not safe since the file may change between the call to stat() and the call to open(). Safer to just open() the file and then do fstat() using the filedescriptor returned by open.

| * modpost: Fix address calculation in reloc_location()Olof Johansson2010-12-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes a segfault in modpost that is observed when the gold linker is used to link the input objects. The problem is that reloc_location (modpost.c) is computing the address of the relocation target incorrectly. Here, elf->hdr points to the beginning of the ELF file in memory, sechdr points to the relocation section header, section is the index of the section being relocated, and sechdrs[section].sh_offset would be the offset of that section, relative to the beginning of the ELF file. Adding elf->hdr + sechdrs[section].sh_offset gives you the address of the beginning of the section, and adding r->r_offset to that gives you the address of the location to be relocated. You do not need to subtract sechdrs[section].sh_addr from that -- the result of this is an address outside the file, and causes the segfault when addend_386_rel tries to dereference it. This bug is not observed when GNU ld is used to link the inputs. The object file ubuntu/omnibook/omnibook.o is the result of an ld -r of several other files. When GNU ld does an ld -r, it sets the vaddr field for each section to 0, but gold lays out the section addresses sequentially instead: Section Headers: [Nr] Name Type Addr Off Size ES Flg Lk Inf Al [ 0] NULL 00000000 000000 000000 00 0 0 0 [ 1] .text PROGBITS 00000000 000034 004794 00 AX 0 0 4 [ 2] .data PROGBITS 0000b9d0 0047c8 0009c0 00 WA 0 0 4 [ 3] .bss NOBITS 000162f8 005188 00013c 00 WA 0 0 4 [ 4] .rodata.str1.1 PROGBITS 00004f2d 0052c4 001b1a 01 AMS 0 0 1 [ 5] .init.text PROGBITS 00004794 006dde 0005fa 00 AX 0 0 1 [ 6] .exit.text PROGBITS 00004d8e 0073d8 00018a 00 AX 0 0 1 ... So the bug in the tool remained undiscovered because the section's vaddr always happened to be 0.

| * kbuild: fix interaction of CONFIG_IKCONFIG and KCONFIG_CONFIGBen Gardiner2010-12-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If you try to build a kernel with KCONFIG_CONFIG set (to a value not equal to .config) and that config sets CONFIG_IKCONFIG then the build will fail with: make[1]: *** No rule to make target `.config', needed by \ `kernel/config_data.gz'. Stop. because the kernel/Makefile contains a direct reference to .config. This issue has been present since the introduction of KCONFIG_CONFIG in 14cdd3c402bf7c66f0bcd76e290f0770a54a4b21.

This causes Kconfig warnings when it is selected by various architectures, such as warning: (ARCH_VEXPRESS && <choice> || ARCH_RPC && <choice> || MACH_VPAC270 && ARCH_PXA || MACH_REALVIEW_PB11MP && ARCH_REALVIEW || MACH_REALVIEW_PBA8 && ARCH_REALVIEW || MACH_REALVIEW_PBX && ARCH_REALVIEW || MACH_BAST_IDE && ARCH_S3C2410 || MACH_ANUBIS && ARCH_S3C2410) selects HAVE_PATA_PLATFORM which has unmet direct dependencies (ATA && ATA_SFF) Since this option is only used to control visibility of the CONFIG_PATA_PLATFORM option and isn't itself visible in the menu, it is straightforward to simply remove these dependencies rather than adjust all the architectures.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have a memory leak in drivers/hid/hid-picolcd.c::picolcd_debug_out_report() in an error path.. We are not always freeing the memory allocated to 'buff' - this patch makes sure we always kfree() what we allocate with kmalloc() when it is no longer needed.

The first one is an emulation of a touchscreen by sending left and right button, and the second mode is the one used in dual-touch (sending trackingID, touch and else). In case of a suspend/resume, the device switch back to the first mode described above (with left and right buttons). This adds a hook in .reset_resume for the device to be switched to the correct mode (I just copied the code in mosart_probe).

The device has 2 modes. The first one is an emulation of a touchscreen by sending left and right button, and the second mode is the one used in dual-touch (sending trackingID, touch and else). That's why there is a hid report containing left and right buttons (9000001 and 9000002). The point is that xorg relies on these fields to determine if it's a touchpad or a touchscreen. Clearing the report (return -1) makes xorg detecting it out of the box as a quite pleasant (dual)touchscreen.

This would be fine in the normal mode, but the driver puts the device in multitouch mode where no relative events are generated. Also, userspace software depends on accurate axis information for device type detection. Thus, ignoring the relative axes from the Magic Trackpad is best.
