2015-07-18configfs: fix kernel infoleak through user-controlled format stringNicolas Iooss2-3/+3
Some modules call config_item_init_type_name() and config_group_init_type_name() with parameter "name" directly controlled by userspace. These two functions call config_item_set_name() with this name used as a format string, which can be used to leak information such as content of the stack to userspace. For example, make_netconsole_target() in netconsole module calls config_item_init_type_name() with the name of a newly-created directory. This means that the following commands give some unexpected output, with configfs mounted in /sys/kernel/config/ and on a system with a configured eth0 ethernet interface: # modprobe netconsole # mkdir /sys/kernel/config/netconsole/target_%lx # echo eth0 > /sys/kernel/config/netconsole/target_%lx/dev_name # echo 1 > /sys/kernel/config/netconsole/target_%lx/enabled # echo eth0 > /sys/kernel/config/netconsole/target_%lx/dev_name # dmesg |tail -n1 [ 142.697668] netconsole: target (target_ffffffffc0ae8080) is enabled, disable to update parameters The directory name is correct but %lx has been interpreted in the internal item name, displayed here in the error message used by store_dev_name() in drivers/net/netconsole.c. To fix this, update every caller of config_item_set_name to use "%s" when operating on untrusted input. This issue was found using -Wformat-security gcc flag, once a __printf attribute has been added to config_item_set_name().

2015-07-18include, lib: add __printf attributes to several function prototypesNicolas Iooss12-30/+36
Using __printf attributes helps to detect several format string issues at compile time (even though -Wformat-security is currently disabled in Makefile). For example it can detect when formatting a pointer as a number, like the issue fixed in commit a3fa71c40f18 ("wl18xx: show rx_frames_per_rates as an array as it really is"), or when the arguments do not match the format string, c.f. for example commit 5ce1aca81435 ("reiserfs: fix __RASSERT format string"). To prevent similar bugs in the future, add a __printf attribute to every function prototype which needs one in include/linux/ and lib/. These functions were mostly found by using gcc's -Wsuggest-attribute=format flag.

2015-07-18s390/hugetlb: add hugepages_supported defineDominik Dingel1-0/+1
On s390 we only can enable hugepages if the underlying hardware/hypervisor also does support this. Common code now would assume this to be signaled by setting HPAGE_SHIFT to 0. But on s390, where we only support one hugepage size, there is a link between HPAGE_SHIFT and pageblock_order. So instead of setting HPAGE_SHIFT to 0, we will implement the check for the hardware capability.

2015-07-18mm: hugetlb: allow hugepages_supported to be architecture specificDominik Dingel1-9/+8
s390 has a constant hugepage size, by setting HPAGE_SHIFT we also change e.g. the pageblock_order, which should be independent in respect to hugepage support.

2015-07-18revert "s390/mm: make hugepages_supported a boot time decision"Dominik Dingel3-8/+4
Heiko noticed that the current check for hugepage support on s390 is a little bit too harsh as systems which do not support will crash. The reason is that pageblock_order can now get negative when we set HPAGE_SHIFT to 0. To avoid all this and to avoid opening another can of worms with enabling HUGETLB_PAGE_SIZE_VARIABLE I think it would be best to simply allow architectures to define their own hugepages_supported().

In case the gpiochip doesn't have the .dev field set, as is the case in here, it is not possible to reference this device in DT as a GPIO controller. A good example of this problem is that gpio-leds can not be used when connected to this chip, the gpio-leds driver bails out with -EPROBE_DEFER.

xgpio_save_regs() is used in this driver to setup the initial values of the registers in the hardware. The relevant registers at that time are: 0x0 -> channel 0 data (32 bits, one for each GPIO on this channel). 0x4 -> channel 0 tri, controls in/out status for each GPIO of this channel. 0x8 -> channel 1 data 0xC -> channel 1 tri gpio-xilinx.c defines these: XGPIO_DATA_OFFSET (0x0) XGPIO_TRI_OFFSET (0x4) XGPIO_CHANNEL_OFFSET 0x8 Before this patch, the "data" register value of channel 1 was written at 0x4 intead of 0x8 (overwriting the channel 0 "tri" register), and the "tri" register value for channel 1 was written at 0x8 instead of 0xC.
