f2abeef Laurent Dufour 17 July 2015, 23:23:58 UTC mm: clean up per architecture MM hook header files Commit 2ae416b142b6 ("mm: new mm hook framework") introduced an empty header file (mm-arch-hooks.h) for every architecture, even those which doesn't need to define mm hooks. As suggested by Geert Uytterhoeven, this could be cleaned through the use of a generic header file included via each per architecture asm/include/Kbuild file. The PowerPC architecture is not impacted here since this architecture has to defined the arch_remap MM hook.

3958b79 Nicolas Iooss 17 July 2015, 23:23:45 UTC configfs: fix kernel infoleak through user-controlled format string 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().

8db1486 Nicolas Iooss 17 July 2015, 23:23:42 UTC include, lib: add __printf attributes to several function prototypes 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.

7f9be77 Dominik Dingel 17 July 2015, 23:23:39 UTC s390/hugetlb: add hugepages_supported define 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.

41318bf Dominik Dingel 17 July 2015, 23:23:34 UTC revert "s390/mm: make hugepages_supported a boot time decision" 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().

2252607 Gregory Fong 18 June 2015, 01:00:40 UTC gpio: brcmstb: fix null ptr dereference in driver remove If a failure occurs during probe, brcmstb_gpio_remove() is called. In remove, we call platform_get_drvdata(), but at the time of failure in the probe the driver data hadn't yet been set which leads to a NULL ptr dereference in the remove's list_for_each. Call platform_set_drvdata() and set up list head right after allocating the priv struct to both avoid the null pointer dereference that could occur today. To guard against potential future changes, check for null pointer in remove.

In moving that call to the correct spot, I also moved some exceptional truncate code earlier as well, since the early error paths don't need to deal with it, and I renamed out4: to out_tx: so a future patch by Jan Kara doesn't need to deal with renumbering or confusing out-of-order labels.

Use drm_format_plane_cpp() instead. This also revealed a problem in that YUYV formats toggle the U/V data for odd pixel start address offsets. We try to rectify that by toggling the U/V swap, which for the most part works, but seemingly introduces a flicker for one scan frame of swapped U/V.

c426877 Yuval Shaia 12 July 2015, 08:24:09 UTC IB/ipoib: Scatter-Gather support in connected mode By default, IPoIB-CM driver uses 64k MTU. Larger MTU gives better performance. This MTU plus overhead puts the memory allocation for IP based packets at 32 4k pages (order 5), which have to be contiguous. When the system memory under pressure, it was observed that allocating 128k contiguous physical memory is difficult and causes serious errors (such as system becomes unusable). This enhancement resolve the issue by removing the physically contiguous memory requirement using Scatter/Gather feature that exists in Linux stack. With this fix Scatter-Gather will be supported also in connected mode. This change reverts some of the change made in commit e112373fd6aa ("IPoIB/cm: Reduce connected mode TX object size"). The ability to use SG in IPoIB CM is possible because the coupling between NETIF_F_SG and NETIF_F_CSUM was removed in commit ec5f06156423 ("net: Kill link between CSUM and SG features.")

4fabb59 Wengang Wang 06 July 2015, 06:35:11 UTC rds: rds_ib_device.refcount overflow Fixes: 3e0249f9c05c ("RDS/IB: add refcount tracking to struct rds_ib_device") There lacks a dropping on rds_ib_device.refcount in case rds_ib_alloc_fmr failed(mr pool running out). this lead to the refcount overflow. A complain in line 117(see following) is seen. From vmcore: s_ib_rdma_mr_pool_depleted is 2147485544 and rds_ibdev->refcount is -2147475448. That is the evidence the mr pool is used up. so rds_ib_alloc_fmr is very likely to return ERR_PTR(-EAGAIN). 115 void rds_ib_dev_put(struct rds_ib_device *rds_ibdev) 116 { 117 BUG_ON(atomic_read(&rds_ibdev->refcount) <= 0); 118 if (atomic_dec_and_test(&rds_ibdev->refcount)) 119 queue_work(rds_wq, &rds_ibdev->free_work); 120 } fix is to drop refcount when rds_ib_alloc_fmr failed.

a7f2f24 Tatyana Nikolova 02 July 2015, 17:47:44 UTC RDMA/core: Fixes for port mapper client registration Fixes to allow clients to make remove mapping requests, after they have provided the user space service with the mapping information, they are using when the service is restarted. 1) Adding IWPM_REG_VALID, IWPM_REG_INCOMPL and IWPM_REG_UNDEF registration types for the port mapper clients and functions to set/check the registration type. 2) If the port mapper user space service is not available to register the client, then its registration stays IWPM_REG_UNDEF and the registration isn't checked until the service becomes available (no mappings are possible, if the user space service isn't running). 3) After the service is restarted, the user space port mapper pid is set to valid and the client registration is set to IWPM_REG_INCOMPL to allow the client to make remove mapping requests.

As such, we should not attempt to query and report the clock offset to user space for VFs. Doing so causes query_device over VFs to fail with -ENOSUPP.

b356c1c Vaishali Thakkar 24 June 2015, 04:42:13 UTC IB/srpt: Convert use of __constant_cpu_to_beXX to cpu_to_beXX In little endian cases, the macro cpu_to_be{16,32,64} unfolds to __swab{16,32,64} which provides special case for constants. In big endian cases, __constant_cpu_to_be{16,32,64} and cpu_to_be{16,32,64} expand directly to the same expression. So, replace __constant_cpu_to_be{16,32,64} with cpu_to_be{16,32,64} with the goal of getting rid of the definitions of __constant_cpu_to_be{16,32,64} completely.
